Importance: Clarifying the underutilization of treatment intensification (TI) for metastatic castration-sensitive prostate cancer (mCSPC) may improve implementation of evidence-based medicine and survival outcomes.
Objective: To investigate physicians' beliefs about TI in mCSPC to understand the gap between evidence-based guidelines and clinical practice.
Design, Setting, And Participants: This survey study analyzed data from the Adelphi Real World retrospective survey, which comprised physician surveys that were linked to medical record reviews of US adult patients treated for mCSPC between July 2018 and January 2022.
Background: Previous studies have shown that Black men receive worse prostate cancer care than White men. This has not been explored in metastatic castration-sensitive prostate cancer (mCSPC) in the current treatment era.
Methods: We evaluated treatment intensification (TI) and overall survival (OS) in Medicare (2015-2018) and Veterans Health Administration (VHA; 2015-2019) patients with mCSPC, classifying first-line mCSPC treatment as androgen deprivation therapy (ADT) + novel hormonal therapy; ADT + docetaxel; ADT + first-generation nonsteroidal antiandrogen; or ADT alone.
