title: [Prognosis after radical surgery in prostatic cancer patients with lymph nodes metastases].
abstract: We investigated prognosis of clinically localized prostatic adenocarcinoma patients who revealed to have had lymph nodes metastases by undergoing radical surgery. Eighty six patients were operated during the last 15 years under the clinical diagnosis of A2, 9 patients, B1, 15 B2, 13 and C, 49, respectively. Total prostatectomy was done to 51, total cystoprostatectomy to 33 and total pelvic excentration to 2 patients. Of these patients, 22.2% with stage A2, 20.2% with B1, 7.7% with B2 and 43.8% with C had positive nodes and the rate of positive nodes in stage C was significantly higher than that in other stages (p < 0.01). Regarding histological differentiation, 15.4% of well, 23.7% of moderate and 51.6% of poor by differentiated had positive nodes and the rate of positive nodes in poor by differentiated was significantly higher (p < 0.01). In 2 of 21 cases whose lymph nodes were dissected to the level of the aortic bifurcation, positive nodes were detected only in the external and common iliac areas. These two cases were missed, i.e., "false negative" if limited nodes dissection was performed. All patients with positive nodes were treated with hormonal therapy. The 5-year cancer specific survival rate of patients with positive (n = 27) and negative (n = 59) nodes were 66.4% and 92.4%, respectively. The prognosis of patients with positive nodes were significantly worse than that of patients with negative nodes (p < 0.001). Among 27 patients with positive nodes, significant prognostic factor was not number or extent of positive nodes, but histological differentiation.(ABSTRACT TRUNCATED AT 250 WORDS)
