Description

A total of 42 patients with hormone-refractory prostate cancer received E-E therapy. Oral estramustine phosphate (EMP) was administered twice daily for a total daily dose of 560 mg every day and oral etoposide (E-E therapy, 50 mg/body/day) was given on days 1-21 and stopped on days 22-35. Treatment was continued until the disease progression was confirmed radiographically or PSA had increased from base line of at least 25%. The median follow-up period after E-E therapy was 77.4 months (range : 12.5 to 122.3). Nineteen patients (43%) achieved a PSA decrease of 50% or greater. The median survival time of the patients who had a decrease of 50% or greater in the PSA value (PSA responder) was 29.3 months and the patients who did not (PSA non-responder) was 14.1 months (p = 0.01). There were no significant differences between PSA responders and non-responders when taking into account variables. Excluding those patients with only PSA elevation, the survival time was 14.9 months with no significant difference between PSA responders and non-responders. The toxicities (grade 3 or more) were identified as anemia, leukocytopenia thrombocytopenia, cardiovascular events, and gastrointestinal and hepatic disorders, which occurred in 0, 5, 2, 2, 14, and 2% of the patients, respectively. E-E therapy was considered to be an active oral regimen and well-tolerated for outpatients with hormone-refractory prostate cancer in Japanese patients.
