Results

Most of castration-resistant prostate cancer patients were classified into good-risk group according to the Armstrong risk classification and the Armstrong risk classification could predict
prognosis in docetaxel-treated castration-resistant prostate cancer patients.

Other related information

Castration-resistant prostate cancer patients who received 2 or more docetaxel cycles are selected for this study. The patients are classified into good-, intermediate-, and poor-risk groups according to the Armstrong risk classification. Overall survival and prostate-specific antigen responses are calculated and compared between the risk groups.
