title: [Histopathological effect of neoadjuvant chemohormonal therapy for prostatic cancer].
abstract: To improve the therapeutic results in prostatic cancer, radical prostatectomy or total cystoprostatectomy were performed with chemohormonal therapy before operation. Radical prostatectomies were conducted in eight patients with localized prostatic cancer and total cystoprostatectomies in ten patients with severe cystic infiltration. The administration schedule of chemohormonal therapy was as follows: prior to operation, 30-60 mg/sqm/day of etoposide was administered for 7 days every 3 weeks, 250-500 mg/day of diethylbestrol diphosphate for 30 days, and 3.6 mg of LH-RH agonist was also administered. Sixteen of the subjects survived, and were socially rehabilitated (14 cases of NED, 1 case of NC and 1 case of PD) and 2 of the subjects died of cancer. Histopathological findings showed 9 cases of poorly differentiated adenocarcinoma, 4 cases of well differentiated adenocarcinoma and 5 cases of moderately differentiated adenocarcinoma. Histopathological effect of neoadjuvant chemohormonal therapy in surgical specimen showed that 2 of the subjects had grade 0a effect, grade 0b in 7 cases, grade 1 in 5 cases and grade 2 in 4 cases.
