We report a retrospective study on the efficacy, adverse events and the factors for continuous docetaxel (DOC) therapy for patients with castration-resistant prostate cancer (CRPC). Between April 2007 and April 2015, 37 CRPC patients were treated with DOC therapy at Kanazawa Medical University Hospital. DOC was administered every 3 weeks at 70 mg/m2. Prostatic specific antigen (PSA) level, adverse events, cycles of DOC therapy, survival time and clinical passage were examined. Fifteen patients showed a decrease in PSA level of 50% or more, 9 patients showed less than 50% decrease in PSA level and 13 patients showed no decrease in PSA level. Adverse effect of grade 3 consisted of neutropenia in 29.7% and leukocytopenia in 10.8%. The median number of treatment cycles was 11.7 courses. The patients were divided into two groups ; the first group comprised of 26 patients who received short-term DOC therapy (≤10 cycles) and the second group comprised of 11 patients who received long-term DOC therapy (≥11 cycles). The 1-year survival rate was 59 and 100% for the short-term and long-term groups, respectively. Long-term treatment was related to pretreatment PSA nadir, time to progression of CRPC and serum lactate dehydrogenase level.
