Hello and welcome to the ASCO Guidelines podcast series. My name is Shannon McKernin, and today I'm interviewing Dr. Shlomo Koyfman from the Cleveland Clinic, lead author on "Management of the Neck in Squamous Cell Carcinoma of the Oral Cavity and Oropharynx: ASCO Clinical Practice Guideline." Thank you for being here today, Dr. Koyfman. It's a pleasure. So first, can you give us a general overview of what this guideline covers? Yeah, so this is an exciting guideline because it covers a topic that we don't usually think about in head and neck cancer in a formal way, and that is management of the neck in squamous cell cancer of the oral cavity and the oropharynx. So there's a lot of literature and guidelines out there on how to manage oropharynx cancer, which is becoming a more and more common cancer, especially in the HPV-positive era, less so on oral cavity. But a lot of times it's focused on people who don't get surgery, chemoradiation, or people who do get surgery and TORS, Transoral Robotic Surgery, and different approaches. But rarely do we have something focus on management of the neck per se, which is really, really important in these cancers and often overlooked in favor of the primary tumor itself. So these guidelines really take us through some salient questions in how to manage the neck in these two cancers. And what are the key recommendations of this guideline? The recommendations came off of six fundamental questions, three in oral cavity and three in oropharynx. There are some commonalities between the two and some differences. A lot of the fundamental questions revolve around surgical quality, and neck dissection is the standard surgical approach for management of the neck in these patients. And as we enter the quality era, how do we define benchmarks of surgical quality, which is one thing that it deals with. The other is when to do adjuvant therapy like adjuvant radiation or chemoradiation. We also deal with when to do surgery for the neck or to do nonoperative approaches like radiation or chemoradiation. And then lastly, how do you follow patients after you've treated them? So those are kind of the salient issues that we dealt with. And what we came out with was nothing earth shatteringly new, but I think the way it was organized and systematically put together, I think it's going to be really, really helpful for people. So some of the most important findings that this recommendation does, I think this is the first that incorporates surgical quality, as I mentioned before. So specifically neck dissection should have 18 or more nodes as multiple studies have shown that that's associated with better outcomes. And similarly we define for different diseases of oral cavity and oropharynx, and depending on what kind of tumor it is and where, what nodal levels should be dissected or treated, whether surgically or nonsurgically, and when to do just one side of the neck versus both sides of the neck. So I think there's a lot of good guidance there in terms of the surgical quality. From a standpoint of adjuvant therapy, we define pretty clearly indications for when after surgery for oral cavity cancer, for example, when radiation should be added and when chemoradiation should be added, and I think that's very helpful. And especially for the neck itself, there's been confusion about what happens if I have 30 nodes taken out and they're all negative but I have a big, large primary tumor. What do I do with the neck? Do I radiate it? Do I not radiate it at one side, both sides? And this guideline gives some pretty clear guidance in different scenarios about how to think about that, which is pretty novel and really important, I think. I get questions about this all the time. It comes up in tumor boards all the time, and it's pretty practical. And mostly what we say is if you have a primary tumor that's like a T3 or T4 oral cavity cancer or it approaches midline, either a contralateral neck dissection should be done or radiation should be done to the contralateral neck. And even if you have a lot of lymph nodes taken out and they're negative, if you have very high-risk primary tumor features like very large tumor or multifocal perineural invasion, those kinds of things, even with a negative neck dissection we still typically do treat the neck. So the next recommendation that's really helpful is who can be observed after surgery? And specifically low-volume N1 you can consider observing in oral cavity cancer, whereas N2 or N3 patients all need radiation or chemoradiation in the setting of extranodal extension and positive margins. We did come out pretty firmly advocating for bolus cisplatin 100 milligrams per meter squared every three weeks as recent studies suggest that weekly cisplatin or other regimens are not as effective, and we were pretty clear about that. We were pretty synchronized with recent ASCO-endorsed guidelines in oropharynx cancer that say similar things. In addition, one of the very important questions that comes up is a surgeon will say, well, I'm cutting out the neck tumor, and I know it comes to midline and he's got a bunch of nodes on the right side, but do I really need to do a left neck dissection? Aren't you going to radiate it anyway? And that comes up all the time. Is radiation adequate to manage a clinically negative neck in oral cavity cancer and oropharynx cancer? I think in oropharynx cancer everybody feels pretty comfortably yes. I think in oral cavity cancer it's been somewhat controversial. We favor neck dissections when possible, but if radiation is known to be happening, especially to an elective contralateral neck, that that is adequate therapy. However, we're pretty strong in the fact that neck dissections are the tried and true way to treat oral cavity cancer and that in a T2 or above tumor where a neck dissection is indicated, just resecting the primary and leaving the neck to elective radiation is not something that we thought there was enough evidence for to advocate, and we still advocate classic neck dissection first followed by adjuvant radiotherapy as indicated. One area of controversy that we did touch on is the issue of early stage tongue cancers and whether they need a neck dissection at all. And we came down pretty consistently with all of the co-authors on the guideline that we advocated for a neck dissection for all patients with oral cavity cancer unless it is a very small tumor that we define with very compliant patient who is amenable to very rigorous follow-up that has been done in Europe and in some other places with, specifically, people trained in careful neck ultrasound techniques. So all of those really help guide, both in early stage and more advanced stage, how to manage the neck and oral cavity cancer. And in oropharynx cancer, again, many of the same quality metrics apply. We have some guidance about when doing transoral robotic surgery how to reduce bleeding risk by ligating feeding blood vessels, which is an important addition. We also discuss the fact that, as opposed to lateralized oral cavity patients where a unilateral either neck dissection of radiation is often indicated, in oropharynx cancer the group felt very strongly that bilateral neck should be treated. And typically if tumors extend to midline or involve the posterior oropharyngeal wall, which has bilateral drainage, that either bilateral neck dissection should be performed in those cases or a unilateral neck dissection can be done as long as adjuvant radiation is planned to both necks. Finally, a couple of very important questions of who should not be treated surgically and who should be treated with a nonoperative chemoradiation based approach. In oral cavity cancer, as long as they were not metastatic, we felt people should be resected as long as they were surgically resectable and medically operable. In oropharynx cancer, however, anybody who had unequivocal extranodal extension of nodes into soft tissues or involvement to the carotid artery or extensive cranial-nerve involvement or skull-based involvement by extensive nodal disease are not good candidates for surgery and should be preferentially treated with chemoradiation. That was pretty strong. And finally, the other thing we gave clarity on is when we treat oropharynx cancer with chemoradiation, how do we follow them and when do we decide to do a neck dissection or not? And essentially we recommended a PET CT scan at 12 weeks. And as long as that was negative, a neck dissection should not be done. If you don't have a PET scan and you just have high quality CT or MRI but all of the neck disease has resolved, similarly there should be no neck dissection. And then most importantly, the situation we all face which is very complex is what happens when you have a PET CT done three to four months after treatment and you have small nodes that are still there? You have a little bit of uptake. The FDG avidity is much less than it was. There still is a lesion there, but it's much better and the patient is feeling well. And we felt pretty comfortable not doing a standard neck dissection on those patients but rather following them closely with a follow-up CT scan two to three months later and continual assessment and reserving surgery for obvious progressive disease. So why is this guideline so important, and how will it change practice? So this guideline is really important because head and neck cancer being not the most common cancer, and especially because head and neck cancer is not really one disease-- there's so many different diseases. Even oral cavity and oropharynx, there's quite a bit of variability in how we think about it. There's not a one size fits all recipe for how to manage people properly, and that leads to a lot of confusion and sometimes doubt as to what the best thing to do is in these patients. And that is a very common thing. So I think the most important reason why these guidelines are helpful is they're really clear. They give really clear guidelines of if you're going to do surgery, here's the expectations of what nodal levels to take out and how many nodes to take out. Here's when you should do adjuvant radiation. Here's when you should do adjuvant chemoradiation. Here's when you should treat one side of the neck. Here's when you should treat both sides of the neck. If you're not going to do surgery, here's when you do radiation. And for oropharynx cancer, here's when you can consider surgery. Here's where surgery is not the best idea. And when you treat them and if you do surgically, here's how you do it. If you do with radiation, here are the nodes that should be treated, the nodal levels. And finally, after you do that, how do you watch and act to make sure that people don't fail? So I feel like all of those things lend a lot of clarity to some complicated decision-making processes for these patients, and this really lends clarity to that, which should help kind of lend consistency of practice. That's really our goal. Our goal was there a lot of great docs taking care of these patients out there, but patients are treated in very different ways depending on who they're seeing and where you go. Our goal was to try to increase the consistency of how people are treated no matter where they are. And if practitioners, surgeons, radiation oncologists, medical oncologists see this guideline and kind of follow it and, of course, reach out with any questions at any time, then what we'll be able to do is kind of harmonize the way patients are treated in this country, which should help, I think, the quality of care. And finally, how will these guideline recommendations affect patients? They're going to affect patients because right now a lot of patients get great care, but there are some patients that are not getting ideal care either because maybe they're in parts of the country that don't have the same access to resources or they're in places where the volume of these kind of very complicated and yet not so common diseases aren't seen as high and there's confusion about how to manage them or what the quality metrics are. I think patients are going to be affected knowing, hey, if I'm going to have a neck dissection, here's what I should be asking to make sure my surgeon knows to do and does consistently to make sure it's of high quality. Here's where I think I should be treated with surgery, maybe I shouldn't be treated with surgery, and here's how to follow me. Because there is a lot of variability in how patients are treated, and sometimes there's too many surgeries being done, not enough surgeries being done. If they're being done, maybe they're not the best quality. Even if we don't treat with surgery and we do chemoradiation, we're watching them and we may not be following them as closely, and then people may be recurring and we're not picking it up closely enough. So I think it's going to harmonize, for patients, the way they're ultimately treated. If everybody in the country is treated relatively compatible with this guideline, I think the standard of care will go up across the board. Great.

Hello and welcome to the ASCO Guidelines podcast series. My name is Shannon McKernin, and today I'm interviewing Dr. Randy Taplitz from UC San Diego Health, lead author on Antimicrobial Prophylaxis for Adult Patients With Cancer-Related Immunosuppression: ASCO and IDSA Clinical Practice Guideline Update. Thank you for being here, Dr. Taplitz. Thank you. So first, can you give us a general overview of what this guideline covers? Yes. I mean, I think we're all aware that infection in the setting of neutropenia associated with cancer chemotherapy is really a major cause of morbidity in these patients. And it's also important to be aware that prevention and appropriate management of febrile neutropenia and infection should thus be a critical focus in cancer care. So the focus of this particular guideline was to evaluate the risk and benefits of antimicrobial prophylaxis in these patients and really to determine evidence-based best practices for prevention of infection and how to go about doing that. So In this guideline, what we do is we identify the groups at risk for febrile neutropenia and really recommend settings for which prophylaxis with antibacterial, antifungal, antiviral medications are indicated. And then as well make recommendations for consideration of vaccination and other measures such as respiratory etiquette, and hand hygiene, and the like that will help reduce the risk of infection in these vulnerable patients. So since this is an update of a 2013 guideline, what are the major changes? And can you tell us a little bit about the research that informed this update? Yes. Really, when you update a guideline, one is informed by review of articles that encompass, in this setting, randomized clinical trials as well as meta analysis of interventions to prevent microbial infections in patients with neutropenia or other types of immunosuppression. And one example of this-- I think one of the better examples-- is we reviewed a large meta analysis of antibiotic prophylaxis in neutropenic patients after chemotherapy that showed that for fluoroquinolone prophylaxis resulted in really significant reductions in all cause mortality and febrile episodes, particularly in patients who were high risk, meaning the hematologic malignancy population and stem cell transplant population. And in that particular population, in fact, the number needed to treat to prevent one death was 29. So therefore, in that high risk population, really as with prior guidelines, the fluoroquinolone prophylaxis is recommended. However, we also reviewed other articles that include emerging data on some of the risks of fluoroquinolone prophylaxis. So for instance, the effect of fluoroquinolone on the intestinal microbiome and its association with selection of fluoroquinolone-resistant bacteria such as Gram-negative rods, as well as selection of organisms such as Clostridium difficile and enterococcus. And then we also reviewed fluoroquinolone toxicities. So what is added to this guideline are some qualifying statements alerting clinicians to really be aware for these concerns and to consider what the clinical spectrum of things like Clostridium difficile infection, et cetera, look like. In terms of antifungal prevention, including pneumocystis prevention, we really haven't made any major changes to this guideline with the exception that in this new guideline, the panel has also started looking at complications associated with immunotherapy and actually makes a suggestion that people consider pneumocystis prophylaxis in the setting of prolonged steroid use when it's used to treat immune-related adverse events that we've begun to see in increasing numbers associated with agents like checkpoint inhibitors and other immunotherapies. In terms of viral infections, the updated guidelines recommend risk assessment for hepatitis B reactivation and then treatment in accordance with other ASCO guidelines and yearly influenza vaccine, as well as really endorsing other vaccines as described in the Infectious Disease Society of America Guideline for Vaccination in Immunocompromised Hosts. So really, those are the main new events since 2013. And what are the key recommendations of this guideline? So the key recommendations-- the first thing is what we call a risk assessment. So after-- what one does is carefully assess, really, what the risk of febrile neutropenia is. And that includes assessment of patient, what the cancer is, and what the treatment-related factors are. And then after they're risk adjusted and risk assessed, then we take, in turn, different forms of prophylaxis that we consider. And so the first one that we always consider is antibiotic prophylaxis against bacterial infections. And the recommendation is still with the fluoroquinolone. And that's recommended for most patients who are at high risk for febrile neutropenia or profound, really prolonged neutropenia, such as those getting therapy for AML, or myelodysplastic syndrome, or stem cell transplant recipients, particularly with myeloablative regimens. In the lower risk groups, such as those with most solid tumors, fluoroquinolone prophylaxis is not recommend. In terms of antifungal prophylaxis, what is recommended is an oral triazole or Micafungin-- for patients, again, at risk for profound protracted neutropenia such as that AML, MDS, stem cell transplant group during that period of neutropenia. When the risk of invasive aspergillus is high, such as in patients with AML or MDS during the neutropenia period while getting chemotherapy, then the consideration of a mold-active triazole is recommended and in addition should be considered in the context of stem cell transplant recipients with graft versus host disease. In terms of PCP prophylaxis, PCP preventive therapies are recommended for those at high risk for PCP, which include those on greater than what we say 20 milligrams of prednisone equivalent a day for over a month, or based on purine analog use. Viral prophylaxis for HSV is recommended for seropositive patients undergoing allogeneic stem cell transplant or leukemia induction. And then as I mentioned before, patients at risk for hepatitis B reactivation are recommended treatment with a nucleoside reverse transcriptase inhibitor. And this is more carefully discussed in the ASCO Provisional Clinical Opinion on Hepatitis-B Virus Screening for Patients With Cancer Before Therapy. It's also recommended that a yearly flu vaccine is given to patients as well as given to family, household contacts, and health care workers. Other vaccination recommendations are as per the Infectious Disease Society of America Guidelines for Vaccination of Immunocompromised Hosts. And then the other things that are recommended are really review and repeat recommendation of adherence with hand hygiene, with respiratory etiquette, which is recommended and really required for all health care workers. And that out patients with neutropenia from cancer chemotherapy should avoid high risk activities, which include really contact with environments that have high concentration of fungal spores such as construction and demolition, high intensity gardening, et cetera. So those are really a summary of the key recommendations of this guideline. And finally, how will these guideline recommendations affect patients? I think it's important to remember that to ensure best practices on infection prevention, the literature needs to be reviewed frequently and guidelines need to be updated. I don't think that these current guidelines will dramatically change the preventive strategies that are used for patients, with the exception of perhaps a few extra vaccines-- some newer indications for pneumocystis prevention, hepatitis B reactivation prevention, those kinds of things. However, I think in reviewing the literature, it becomes clear what will we will need to be thinking about in the coming years, what we will need to be assessing. And a couple of those things are the dramatic increase in the use of immune-based therapies and how that will affect infection risk in patients with or without neutropenia. We need to be considering the effects of routine antibiotic prophylaxis on the microbiome and the risks that that might incur. And we need to really understand how new vaccines can be utilized. So yeah, I think these areas are really ripe for research and need to be followed closely to ensure optimization of these preventive strategies for our patients in the future. Thank you for your time today, Dr. Taplitz. You're quite welcome. And thank you to all of our listeners for tuning into the ASCO Guidelines podcast series.

Hello, and welcome to the ASCO Guidelines Podcast series. My name is Shannon McKernin. And today, I'm interviewing Dr. Manish Shah from New York Presbyterian Weill Cornell Medical Center, senior author on "Treatment of Patients with Early-Stage Colorectal Cancer: ASCO Resource-Stratified Guideline." Thank you for being here today, Dr. Shah. Thank you, it's a pleasure and honor to be here. So first, can you give us a general overview of what this guideline covers? Yes, absolutely. So the "Treatment of Patients with Early-Stage Colorectal Cancer" is a resource-stratified guideline. And it focuses on the management of patients with early-stage colon cancer. It's different than the surveillance and screening guideline that was written simultaneously for ASCO as another resource-stratified guideline. We felt that this was a big enough topic that we should keep it separate. So it really talks about the management of pre-malignant lesions, as well as early-stage colon cancers, as well as rectal cancers. And the other aspect of this is that we really focused on how the guideline may apply in settings where there-- they don't have maximal resources, so basic or limited settings as well. So I would like to talk a little bit about how the guideline was created, because I think that's an important aspect. And it distinguishes it from typical other ASCO Guidelines. So the management of colon cancer or colorectal cancer, there's a lot of literature on this. And there are several guidelines that have been produced by colorectal cancer societies, or surgical societies, or from other countries like the EORTC, or Japan, or Korea, or even the UK. So in fact, there were, I think, 30 to 40 different guidelines that we reviewed. And we felt that, instead of doing a new literature search to kind of rehash much of the same information, we reviewed all the guidelines for certain quality measures to then select a handful of guidelines that we would use as the reference for each of our key questions or key points. And this was done in a formal process, the first by ASCO and Sarah, who was the ASCO staff who wrote the guideline, along with the members of the guideline panel. And in this process, I think that we have a pretty comprehensive guideline that covers the questions with the best evidence available. So what are the key recommendations of this guideline? Yeah, so we addressed some several questions with regard to key recommendations. The first question, for example, was, what's the optimal treatment for patients with colon cancer that would be clinical stage 1 through 3c? And we distinguish that from a non-obstructing cancer to obstructing cancers as well, because the management would be very different. And what we really sort of focused on is that these patients should have resection following oncologic principles. Then ideally, they should have an en bloc resection by a surgical oncologist to give the patients the best chance of care. But I think what's unique to resource-stratified guidelines, and what we have to do is sort of highlight the care that would be achieved in settings that have less resources. So a non-obstructing colon cancer in a basic setting should still have surgery and should still undergo an en bloc resection following standard oncologic principles. So that was, for example, one of the key points that was uniform across all the settings. Other things were how to manage [INAUDIBLE] colon cancer. So in more enhanced and maximal settings, sometimes there might be opportunity to place a colonic stent, for example, by either a colorectal surgeon or by someone who has specialized training in the placement of these stents. And that would be a preferred approach in both the enhanced and maximal guidelines, whereas in a more basic setting, the recommendation was to perform a resection and possibly, if required, if a resection was not possible, a diversion to overcome the obstruction in that localized setting. There were other recommendations that were also important. So for example, in early-stage rectal cancer, so clinical stage 1, T1 and 0 rectal cancer, in a maximal setting, these are sort of low-risk cancers without adverse features like high-grade or involvement of lymphovascular structures. The surgical oncologist and/or colorectal surgeon might consider a local excision such as the TEM procedure, which is a transendomucoscal resection. And in basic or limited settings, we would still recommend surgery in that setting following TME principles to achieve clear margins and a good surgical outcome, because we felt that, in basic-limited settings, the skill and the equipment necessary to do a local excision may not be available. Another recommendation that might highlight the differences between basic and limited settings versus a more maximal setting is the optimal strategy for post-treatment surveillance. So this is after resection of the stage 1 to 3 colorectal cancer. What would be the best way to monitor and surveil patients? And this is the recognition that the purpose of surveillance is to identify recurrence early at a time point where the patient may still be amenable to having local regional resection or resection of the metastatic lesion to change the outcome. So the current ASCO guidelines are to perform a medical history, and physical examination, and a CEA every six months for three to five years, have an abdominal and chest CT scan, in high-risk patients, every 6 to 12 months for three years, and a colonoscopy one year after the surgery, and then every five years or so after that, as indicated, up to age of 75. And that's what we recommended in the maximal and enhanced settings. But in a more basic setting, the recommendation was similarly medical history and physical exam every six months for three years, a CEA every six months for three years, a chest X-ray and abdominal ultrasound twice in the first three years, and a colonoscopy once i the first two years. And then if a colonoscopy is not available, we recommended a double-contrast barium enema or, for left-side tumors, a sigmoidoscopy to try to surveil the local regional extent of the the disease. So I think what we're trying to highlight is that we think that we can help patients for the management of localized early-stage colon cancer, both for treatment as well as for surveillance, and that these recommendations may vary a little bit in more limited settings, but with these recommendations, we can provide the best care for patients overall. And so why is this guideline so important? And how will it change practice? I think that the guideline is really important, because we recognize that we're practicing medicine in the United States, or in Europe, or wherever you practice, but the levels of resources that are available to us are not uniform. And so we really are getting to the aspect that cancer care is a global proposition. And ASCO should reflect that. And so the intention of these resource-stratified guidelines is to try to provide guidance into the best management for the indication across the spectrum of resources that are available. Interestingly, we've also heard from many people who practice in more resource-limited settings that they can use these guidelines to sort of advocate for their own area, to say that, based on our availability, we fit in a criteria that's basic or limited, but we really want to be an enhanced setting, and lobby their governments or their local officials to say, these are areas that we can improve on to take us to the next level, literally. And finally, how will these guideline recommendations affect patients? Yeah, at the end of the day, I think it's very important that we remind ourselves that we're doing this to improve patient care overall. I think, in maximal and enhanced settings, the guidelines kind of reiterate the best practices across [INAUDIBLE] of guidelines that were reviewed. So I think that's a very important thing. And they unify the treatment plan across different practices. But I think most importantly, in basic and limited settings, it provides a benchmark for what should be done. I think, for me, one key thing was that, even in basic and limited settings, we don't want to compromise oncology principles for a surgical resection. You know, it's not appropriate to just resect the tumor but leave some tumor behind to relieve an obstruction. We still need to manage that appropriately. And that is the expectation in a basic setting, for example. So I think that, overall, wherever you are, this guideline provides recommendations to help manage the patient across the resources that are available to you. I think that's very important, because we live in a heterogeneous environment where resources are not uniform across the world. Great, thank you for your discussion of this important guideline.

Hello and welcome to the ASCO Guidelines Podcast Series. My name is Shannon McKernin. And today, I'm interviewing Dr. Lynn Henry from the University of Utah Huntsman Cancer Institute, lead author on "Role of Patient and Disease Factors in Adjuvant Systemic Therapy Decision-Making for Early-Stage, Operable Breast Cancer: Update of the ASCO Endorsement of CCO Guideline." Thank you for being here today, Dr. Henry. Thank you very much for the invitation. So this guideline was updated to incorporate new data from the TAILORx and the MINDACT trials. So can you give us an overview of these trials and their results? Sure. So patients with hormone receptor-positive, HER2 negative breast cancer, are generally treated with anti-estrogen treatment and are sometimes also recommended to have chemotherapy. Since these tumors don't always respond well to chemotherapy, tests have been developed that provide more information about how much benefit, in terms of reduction of the likelihood of cancer coming back, an individual patient is likely to get from treatment with chemotherapy. It is important that the benefit of a treatment outweighs the risk of toxicity from the treatment. Two of those tests are called Oncotype DX and MammaPrint. And they have recently been tested in large clinical trials. So TAILORx is a large prospective trial that tested the Oncotype DX assay. In the Oncotype DX assay, a tumor is tested to get more information about how likely a cancer is to return and how much benefit the patient is likely to get from chemotherapy. Scores on this assay can range from 0 to 100. Previously, a study showed that patients whose tumors had scores of 10 or less, and who received five years of anti-estrogen treatment, were very unlikely to have their tumors return. So chemotherapy is not recommended for them. For patients with higher scores, above 30, we also already knew that chemotherapy is likely to decrease the chance of cancers in those patients, and, so, therefore, we generally recommend chemotherapy for women with higher scores. In the TAILORx trial, the recently reported trial, more than 6,700 women with hormone receptor-positive, HER2 negative, lymph node-negative breast cancer had their tumors tested and were found to have Oncotype DX recurrent scores between 11 and 25, which is in that intermediate range or at the higher end of the low range. Before this trial was conducted, many people with tumors like these, in the intermediate range, were treated with both chemotherapy and endocrine therapy because we weren't sure how much benefit they would obtain from chemotherapy, and we didn't want to leave out a potentially helpful treatment. In this trial, patients were randomized, or randomly assigned by a computer, to treatment with chemotherapy followed by endocrine therapy or to treatment with endocrine therapy alone. The trial was mainly looking at whether leaving out chemotherapy would increase the likelihood of invasive cancer returning. And, luckily, overall, the trial showed that the likelihood of cancer returning in those patients who got endocrine therapy alone, without chemotherapy, wasn't significantly different compared to those who were treated with chemotherapy followed by endocrine therapy. They also looked, specifically, at the group of women who were 50 years of age or younger. So mostly premenopausal women. Now, this was an exploratory question, meaning it provides information that may be correct, but it hasn't been as fully tested as the main question about what do we do for all women? In these younger women, there appeared to be some benefit from chemotherapy in those whose tumors had scores from 21 to 25, and, also possibly, in those whose tumors had scores from 16 to 20. Therefore, we still consider giving chemotherapy to younger women with Oncotype DX scores in the middle range, from 16 to 25, but not to women over age 50. So that was the TAILORx trial. The MINDACT trial was a bit different. It was testing the MammaPrint assay and the trial also included primarily women with hormone receptor-positive, HER2 negative breast cancer. But in this case, most women's sorry lymph nodes were negative, although a few women had up to three lymph nodes involved. In that trial, patient's risk of disease recurrence was assessed in two ways. First, it was assessed based on clinical factors. So the size of the tumor, how many lymph nodes were involved, and the estrogen receptor, progesterone receptor, and HER2 receptors. Second, it was assessed based on genomic factors-- that was using the MammaPrint test. So if patients were low for both clinical factors and genomic factors, they only were treated with anti-estrogen therapy. If they were high for both clinical factors and genomic factors, then they were treated with chemotherapy followed by anti-estrogen therapy. However, if they were high for one and low for the other, then they were randomized to either endocrine therapy alone or chemotherapy followed by endocrine therapy. So it was a little bit of a confusing trial. In the MINDACT trial, those patients who were thought to be high risk based on their clinical risk, so the size of the tumor, the number of lymph nodes, but then found to be low risk on the MammaPrint assay. They found that there was no benefit to treatment with chemotherapy in terms of how likely a woman was to develop distant metastatic disease. And if they were low risk, based on the clinical assessment, then there didn't appear to be a benefit of actually doing the test, the assay, because chemotherapy wouldn't be recommended for the patient, regardless of the results. So that was the MINDACT trial. So what are the new and updated recommendations for the guideline? Yes, so in this guideline, we, based on the TAILORx trial, we made new recommendations for use of the Oncotype DX results. All of these results apply to women with hormone receptor-positive, HER2 negative, lymph node-negative breast cancer. So for women older than age 50, if they have an Oncotype score of 25 or lower, then clinicians may offer endocrine therapy and no chemotherapy. However, for women age 50 or under, if they have an Oncotype score of 15 or lower, 15, then, clinicians may offer endocrine therapy and no chemotherapy. But if the score is 16 to 25, then chemotherapy can be considered in addition to endocrine therapy. So it made a difference in that gray area in the middle. For all women with score 26 to 30, chemotherapy may be considered. And for scores above 30, chemotherapy should definitely be considered. The data from the MammaPrint trial actually aren't that new. Results from that trial were originally published in 2016. However, that was after the original guideline was published, so we wanted to add these results to these updated guidelines for completeness. For a patient with hormone receptor-positive, HER2 negative, node-negative breast cancer, who is thought to be at high clinical risk of breast cancer recurrence, if the MammaPrint assay shows low genomic risk, then treatment with chemotherapy can be avoided. If a patient is thought to be at low clinical risk, the MammaPrint should not be used as chemotherapy can be avoided regardless. And for a patient with hormone receptor-positive, HER2 negative breast cancer, but who has one to three positive lymph nodes, who is thought to be at high clinical risk of breast cancer recurrence, if the MammaPrint assay shows low genomic risk, then it is possible that chemotherapy could be avoided, especially if only one lymph node is involved. So I think the bottom line for this part is that both of these tests-- there are now women who previously would have been recommended to have chemotherapy that maybe now we can avoid chemotherapy based on using these assays on their tumors. So why are these changes so important and how will they affect practice? Yes, that's a good question. Before the publication of the TAILORx trial, we had good information about how to treat patients who had either very low or very high Oncotype scores. But we really weren't sure how best to treat those patients who scores fell in the middle. Now, we have important information to guide decisions about chemotherapy for patients with intermediate scores. For many patients with scores in this range, these new results mean they will be able to avoid chemotherapy and just get endocrine therapy. While these results don't give us answers for every patient, they do provide more information that oncologists can use when having discussions with patients about the benefits and risks of chemotherapy. And what does this mean for patients with early-stage invasive breast cancer? And what should they talk to their doctors about? So as a result of both of these trials, we now have additional tools that can help oncologists provide more individualized treatment recommendations for patients and really assess whether or not chemotherapy, in addition to endocrine therapy, is likely to provide benefits. Knowing which patients' tumors will respond to chemotherapy can help some patients avoid unwanted side effects from a treatment that's not likely to actually give them much benefit. Now, these tests aren't appropriate for everyone and don't provide all the answers, but they are an important step in the right direction for providing more personalized treatment for women newly-diagnosed with certain types of breast cancer. Patients should talk with their doctors about whether these tests are right for them when they're making important decisions about whether or not they should receive treatment with chemotherapy. Great. Thank you, Dr. Henry, for this informative overview of the guideline. Keeping these clinical practice guidelines updated is really crucial and it takes a lot of careful thought to ensure these recommendations represent the evidence.

I am Dr. Charles Shapiro, professor of medicine at the Mt. Sinai Hospital in New York. And I'm co-chair of the guideline "Medical-Related Osteonecrosis of the Jaw." And I'm happy to be here. Thank you all for being here today to discuss this guideline on the podcast. So first, can you give us a general overview of what this guideline covers. Sure. So you know, ASCO and MASCC, as well as ISOO decided that it would be great to provide a practical evidence-based approach in a multidisciplinary type setting to address this important topic that impacts all of our professions, that being medication-related osteonecrosis of the jaw. It's terminology and its definition and the path that's varied and even part of this publication identifies the need for us to move forward with a concise definition and similar terminology, that being medication-related osteonecrosis of the jaw. Medication-related osteonecrosis of the jaw is defined as the presence of an exposed or bone that is probable by a probe in a patient that has a history or is undergoing present use of a bone-modifying agent. This being in the absence of any patients having received any radiation to the head and neck and the absence of metastatic lesions to the jaw. The importance of us identifying this definition and agreeing on the terminology allows us to move forward in future publication to better compare outcome and provide better prevention and treatment for our patients moving forward. And what are the key recommendations of this guideline? There are six clinical questions associated with this clinical practice guideline as well as a series of recommendations built within each of the clinical questions. Clinical question one is directed to the preferred terminology and definition for osteonecrosis of the jaw, both of the maxilla and the mandible, as associated with pharmacologic therapies in oncology patients. The panel recommends that the term medication-related osteonecrosis of the jaw, MROJ, be used when referring to bone necrosis associated with pharmacologic therapies. As Dr. Saunders has described, the definition contains three key elements-- current or previous treatment with a bone-modifying agent or angiogenic inhibitor, exposed bone, or bone that can be probed through an intra or extra-oral fistula in the maxillofacial region and that has persisted for longer than eight weeks. And third, no history of radiation therapy to the jaws and no history of metastatic disease to the jaws. Clinical question two is directed to specific steps that should be taken to reduce the risk of MRONJ. The recommendation begins with emphasizing the absolute importance of interprofessional communication of the oncology team with the dental team in advance of initiating the bone-modifying agent. For patients with cancer who are scheduled to receive a bone-modifying agent in a non-urgent setting, a comprehensive oral care assessment, including dental examination and periodontal examination and an oral radiographic exam when feasible to do so should be undertaken prior to initiating the BMA therapy. Once the dental care plan has been developed, it should be discussed with the dental team, the patient, and the rest of the oncology team and then implemented based on medically necessary dental procedures. These procedures should be performed prior to the initiation of the bone-modifying agent. Once the bone-modifying agent is implemented, there should be ongoing followup by the dentist on a routine schedule, for example, every six months following initiation of the BMA therapy. It's also important to realize that there are a series of modifiable risk factors which should be emphasized with the patient. For example, poor oral health, invasive dental procedures, ill-fitting dentures, uncontrolled diabetes mellitus, and tobacco use are all factors that have been associated with development of a MRONJ. All of these modifiable risk factors should be addressed, where appropriate, with the patient in advance of the bone-modifying agent. As far as elective dental alveolar surgery, these procedures, if they are not medically necessary, for example, extractions or alveoloplasties or implants, they should not be performed during active therapy with a bone-modifying agent being given at an oncologic dose. Now, exceptions to this may be considered when a dental specialist with expertise in prevention and treatment of MROJ has reviewed the benefits and risks of the proposed invasive procedures with the patient and the oncology team. In general, however, elective dental alveolar surgical procedures should be deferred while the patient is undergoing active therapy with a bone-modifying agent. If the dental alveolar surgery is performed, the patient should be evaluated by a dental specialist on a systematic and frequently scheduled basis, for example, every six to eight weeks until there is full mucosal coverage of the surgical site. And once again, communication between the dental team and the rest of the oncology team is absolutely paramount in assuring ongoing comprehensive care of the patient. Interestingly, there are still questions in the literature relative to whether or not there should be temporary discontinuation of bone-modifying agents prior to dental alveolar surgery. Unfortunately, there remains insufficient evidence to support or refute the need for discontinuation of the bone-modifying agent prior to dental alveolar surgery. And so the administration of the bone-modifying agent may be deferred at the discretion of the treating physician, in conjunction with discussion with the patient and the oral health provider. So it really becomes an individual judgment call by the treating physician relative to whether or not to temporarily discontinue the bone-modifying agent prior to dental alveolar surgery. Clinical question three involves the staging of MROJ. There are a number of well-established staging systems in the literature addressing severity and extent of MROJ. For example, the 2014 American Academy of Oral and Maxillofacial Surgeons Staging System is one example. Another example is the National Cancer Institute's Common Terminology Criteria For Adverse Events. And there is a 2017 International Task Force on O and J Staging System for MROJ that is available as well. So there are at least three well-established, widely utilized staging systems for MROJ. Having said this, it's important in the view of the panel that the same staging system should be used throughout an individual patient's MROJ course of care. And optimally, the staging should be performed by a clinician experienced with the management of MROJ. Clinical question four involves management of MROJ directly. Here, the recommendations talk in terms of initial treatment of MROJ, which is centered in conservative measures. Now, these conservative measures may include antimicrobial mouth rinses, antibiotics if clinically indicated, effective oral hygiene, and conservative surgical intervention such as a removal of a superficial bone spicule. In cases, however, of refractory MROJ, more advanced MROJ, aggressive surgical interventions, for example, mucosal flap elevations, bloc resections of necrotic bone may be used if MROJ is persisting and severely affects function despite conservative initial treatment. Clinical question five involves bone-modifying agents and whether they should be temporarily discontinued after a diagnosis of MROJ has been established. And once again, there is insufficient evidence to support or refute the discontinuation of the bone-modifying agents after a diagnosis of MROJ has been established. The bone-modifying agent may be deferred at the discretion of the treating physician, again in discussion with the patient and the oral health care provider. And finally, clinical question six involves what outcome measures that should be utilized in clinical practice to describe the response of MROJ lesion to treatment. During the course of MROJ treatment, the dentist, dental specialist, should communicate with a medical oncologist in an ongoing way, both the objective and subjective status of the lesion. The guideline presents a scale that can be utilized to describe the trajectory of the MROJ-- resolved, improving, stable, or progressive. The clinical course of MROJ may impact both local and systemic treatment decisions relative to the cessation or the recommencement of bone-modifying agents. So once again, it becomes very, very important that the ongoing interprofessional communication relative to the clinical course of MROJ-- resolved, improving, stable, or progressive-- be discussed with the oncology team. Great. Thank you, Dr. Peterson. So on that last note, how can oncologists, dental specialists, and dentists all work together to manage medication-related osteonecrosis of the jaw? Throughout these guidelines, we do emphasize the importance of collaboration among the cancer care team, dentist, and dental specialists in order to coordinate care and modify risk factors. It is very important that cancer care team and the dental care team speak the same language. Therefore, we spend time on clarifying the definitions, the diagnostic criteria, and staging of MROJ. As been said earlier, we have developed a new system to evaluate the response to treatment, which is based both on objective findings and symptoms. By using this scale, oncologists and dentists would be able to communicate more easily for the benefit of the patients. We emphasized the need for multidisciplinary discussion in a few critical points throughout the course of bone-modifying agent therapy. And it is most important in case of a planned oral surgery in a patient without MROJ or before aggressive surgical treatment of refractory MROJ. And how will these guideline recommendations affect patients, and what should they talk to their doctors about? There are a number of things that patients, providers, dental specialists, and medical oncologists can do to lessen the risk and prevent MROJ. Because the key to MROJ is prevention. Once MROJ is established, it's difficult to treat, impacting a patient's quality of life. So we want to prevent, reduce the risk of developing MROJ. Patients can do a number of things-- pursue good oral hygiene, stop smoking, or reduce smoking, and control their diabetes, for example. Those things lessen the risk of MROJ. Providers, dental providers, dental specialists, who are specialized in the area or providers, dentists otherwise in the community, when they encounter a patient that's contemplating bone-modifying agents, they can do what's called a complete dental screening exam, which involves a complete examination of the mouth, Panorex X-rays and X-rays as clinically indicated. We want to identify work in the mouth that needs to be repaired before initiating bone-modifying agents. That way, we don't have to deal with an emergent situation when it could be preventable prior to bone-modifying agents, because one of the single highest risk factors for MROJ is emergent dental work while you're on bisphosphonate or another anti-resorptive agent-- bone-modifying agents. So a dental screening exam is critical to prevent or reduce the risk of MROJ. And medical oncologists have a role too in communication with the dental specialists and really think hard about the indications for bone-modifying agents, whether it be for osteoporosis, whether it be for metastatic disease, and whether it be for anti-cancer effects. And finally, where can both patients and clinicians go to get more information on this topic or to find a dentist or a dental specialist? Now, as far as websites, ASCO, MASCC, and ISSO all have websites you can go to to find out more information about MROJ. Yeah, I think that's great advice. Our links for additional information are listed in the Clinical Practice Guideline as well. This is a really first step at a framework in trying to manage a side effect that affects our patients but is very multidisciplinary. And like Dr. Shapiro was saying, really the best way to prevent this is with proper communication between the dentist and the oncologist and making the patient aware of what is needed prior to commencement of these treatments. Well, it certainly sounds as though there are some important considerations for clinicians and patients. And I really hope that this guideline is widely read and makes a real impact on the management of osteonecrosis and the communication between oncologists, dental specialists, and dentists.
