Patients with Stage D2 prostate cancer relapsing on endocrine treatment have a grim prognosis. The role of a second-line hormonal treatment is debatable. We analyzed retrospectively, response and survival among 119 men (57 black, 62 white) progressing on a variety of first-line hormonal therapy. Sixty-one received a second-line hormonal treatment. Fifty-eight received only supportive therapy after first line therapy was discontinued. Age and race were not a factor in survival. Based on this retrospective study the optimal management for progressive metastatic prostate cancer cannot be delineated. However, the best results were in patients treated with diethylstilbestrol (DES) as a single treatment or when employed as either first or second treatment in patients receiving two therapies. The other modalities, e.g., bilateral orchiectomy, LH-RH analogues, and anti-androgens resulted in comparable outcomes when used either as single treatment or in combinations. Further clarification of the trends shown in this report require randomized controlled studies.
