SHOW NOTES

First, Dr. Spratt defines high risk prostate cancer and discusses how to evaluate non-specific PSMA PET findings. He notes the importance of standardized systems to avoid over-calling such findings and discusses the role of CT scans and MRI scans when necessary. Finally, the doctors emphasize the importance of synthesizing PSMA PET findings into their decision-making. Next, the doctors discuss the use of germline and genomic testing, specifically Decipher testing, to characterize the tumor. Germline testing can determine eligibility for neoadjuvant PARP inhibitor trials, and biomarkers have the potential to improve radiation therapy outcomes. Although they quickly summarize the NCCN guidelines, they also emphasize the importance of patient counseling to determine the right treatment plan.

Then, the doctors move on to discuss the different radiation treatments available for treating high-risk prostate cancer, such as conventional fractionation, brachytherapy, and ultrahypofractionated radiotherapy. They also explain the use of protons in treating high-risk prostate cancer, which is difficult because of the lack of high-level evidence and financial benefit when using protons compared to conventional radiation treatments.

Finally, they wrap up the episode by explaining the correlation between early PSA responses and the success of radiation therapy. Surgery and radiation are often used together in treating most cancers, and how combining both can cut down the chances of PSA recurrence.
