Prevalence and Risk Factors of Prostate Cancer
Prostate cancer is the most frequently diagnosed solid tumor in the United States, affecting approximately 300,000 men annually, and it stands as the leading malignancy worldwide. While it poses a significant public health issue, many diagnosed do not face a lethal outcome due to the relatively low lethality rate compared to other cancers like pancreatic or lung cancer. Genetic factors play a crucial role in risk, with about 50% of cases linked to heredity, including notable genes like BRCA2, which significantly increases susceptibility. Additionally, race, particularly among Black men who face a heightened risk for developing aggressive forms of the disease, and age, where men aged 80 have a 65-75% likelihood of developing prostate cancer, are essential considerations in understanding and addressing this disease's prevalence.
Screening and Clinical Presentation of Prostate Cancer
Screening for prostate cancer has evolved, with current guidelines recommending shared decision-making regarding prostate-specific antigen (PSA) testing, especially between the ages of 50 and 69 and earlier for higher-risk groups like Black men. Many men diagnosed with prostate cancer are asymptomatic, indicating that the disease is often indolent in its early stages. When symptoms do occur, they are typically related to urinary obstruction due to prostate enlargement rather than specific prostate cancer symptoms, complicating the screening process. As the approach to screening adjusts, clinicians also need to consider the patient’s age and overall health to determine the appropriateness and timing of screening.
Risk Stratification and Treatment Approaches
Risk stratification in prostate cancer diagnosis is critical as it informs treatment decisions based on factors like Gleason score, PSA levels, and clinical staging. Men with low-risk disease might enter active surveillance, avoiding immediate treatment because of a very low risk of mortality, whereas those with high-risk disease often require aggressive therapy. The treatment landscape for localized prostate cancer is nuanced, with options including surgery and radiation, tailored based on individual patient characteristics and preferences. For metastatic prostate cancer, the first-line treatment typically involves hormone therapy, often with GnRH agonists, and recent advancements emphasize initiating combination therapies early to prolong life and improve outcomes.
Prostate cancer is the most common nonskin cancer in men in the US and the second most common cancer in men worldwide. Author R.
