Inclusion criteria

Inclusion criteria: [ Prospective study ] 1.Patients with localised prostate cancer who received radical prostatectomy (including laparoscopic surgery ) on and after 1st May 2002 (regardless of enforcement of neo-adjuvant therapy and adjuvant therapy). 2.Patients with PSA measurement by the equimolar PSA kit ( except for Merkit-M ) before enforcement of radical prostatectomy. 3.Patients with at least six or more systematic biopsies enforced under the ultrasonic guide. 4.Patients with evaluable clinical stage by TNM classification of malignant tumors ( UICC 1992.Ver.4 ). 5.Patients whose follow-up observation is possible, while measuring PSA periodically after enforcement of radical prostatectomy. (However, follow-up will not be done for patients who undergone adjuvant therapy.) The following patients who filled all of these five conditions. A: Neo-Adjuvant hormone therapy non-enforcing patients. B: Neo-Adjuvant hormone therapy enforcement patients. (Regardless of contents and period ) [ Retrospective study ] 1.Patients with localised prostate cancer patients who underwent radical prostatectomy (including laparoscopic surgery ) from 1st January 1997 to 30th April 2002 (Regardless of neo-adjuvant therapy and adjuvant therapy). 2.And other items are the same as the prospective study, except for the same standards for a positive study will be applied.
