[Clinico-pathological study on prostatic cancer, stage A using step section technic].
Of 52 male bladder cancer cases treated with radical cystectomy, 12 cases (23.9%) were incidentally diagnosed as stage A prostatic cancer. Histological analysis was done according to the "general rules for clinical and pathological studies on prostatic cancer." The average age of the prostatic cancer cases was 62.0 years with a range of 50 to 78 years. Three cases were of well differentiated adenocarcinoma, and 9 cases were of moderately differentiated adenocarcinoma. Six cases were at pT1, 3 at pT2, and 3 at pT3. One case was stage A1, and 11 were stage A2 cases. Perineural and capsular invasions were found in 3 cases each. Neither lymphatic nor vascular invasion was found in any case, and no evidence of seminal vesicular, urethral, bladder and rectal invasion was found in any case. Lymph node metastasis was not found in any of the 3 pelvic lymph node dissected cases.
