Receipt of definitive therapy in elderly patients with unfavorable-risk prostate cancer.

Older age was significantly associated with a decreased likelihood of receiving definitive therapy and an increased likelihood of receiving primary ADT in this national cohort of patients with intermediate-risk or high-risk prostate cancer. Notably, approximately 40% to 45% of patients aged ≥80 years did not receive definitive therapy. These findings are alarming given the dismal outcomes of conservatively managed unfavorable-risk prostate cancer. Cancer 2017;123:4832-40. © 2017 American Cancer Society.
