Prostate cancer (PCa), in particular, is known to cause significant psychosocial distress during the duration of a patient's treatment due to its uncertainty and demasculinizing side effects. Prostate cancer support groups (PCSGs) have been proven to be beneficial, yet are underutilized by the majority of PCa patients and physicians. A thorough review of the literature was performed for articles pertaining to prostate cancer support groups. We sought to identify factors contributing to the psychological burden of the disease, factors that influenced patients to join, and barriers to participation in a PCSG. Additionally, the characteristics and format of PCSGs, as well as outcomes (i.e. quality of life), were evaluated.
