Abstract:

BACKGROUND: Deciding whether to treat or conservatively manage patients with prostate cancer is challenging. Recent changes in guidelines, advances in treatment technologies, and policy can influence decision making surrounding management, particularly for those for whom the decision to treat is discretionary. Contemporary trends in management of newly diagnosed prostate cancer are unclear. METHODS: Using national Medicare data, men with newly diagnosed prostate cancer were identified between 2014 and 2019. Patients were classified by 5- and 10-year noncancer mortality risk. Multinomial logistic regression models were fit to assess adjusted trends in management over time. The primary outcome was management of prostate cancer: local treatment (inclusive of surgery, radiation, brachytherapy, or cryotherapy), hormone therapy, or observation. RESULTS: Local treatment was the most common form of management and stable across years (68%). Use of observation increased (21%-23%, P < .001) and use of hormone therapy decreased (11%-8%, P < 0.001). After stratifying by 10-year non-cancer mortality risk, observation increased among men with low (22.3%-26.1%, P < .001) and moderate (19.9%-23.5%, P < .001) mortality risk. Conversely, use of treatment increased among those with high (62.8%-68.0%, P  =  .004) and very high (45.5%-54.1%, P < .001) risk of noncancer mortality. These trends were similar across groups when stratified by 5-year noncancer mortality risk. CONCLUSION: Nationally, use of local treatment remains common and was stable throughout the study period. However, while local treatment declined among men with a lower risk of noncancer mortality, it increased among men with a higher risk of non-cancer mortality.
