title: [Results of radical nephrectomy associated with regional lymphadenectomy for renal cell carcinoma].
abstract: Between January, 1975 and December, 1989, 86 patients with renal cell carcinoma received radical nephrectomy associated with lymphadenectomy at our institutions. Pathological examination revealed lymph node metastasis in 15 patients (17.4%). The incidence of lymph node metastasis increased in accordance with the aggravation of tumor stage (p less than 0.01) and grade (p less than 0.05). Patients with a rapidly growing tumor showed higher incidence of lymph node metastasis than patients with a slow growing tumor (p less than 0.01). Regional lymph node metastases were found in 3 of the 41 patients with a slow growing tumor. Since these 3 patients are surviving with no evidence of disease for 38.7 months on average, the regional lymphadenectomy was considered to have been effective for their survival. Nine of the 25 patients with a rapid growing tumor had progressive lymph node metastasis. Four of them had apparent tumor thrombi as well as lymph node metastasis, and 2 of them had distant metastasis. These patients showed poor prognosis even after operation. Lymphadenectomy was of no value to the patients with apparent tumor thrombi and/or distant metastasis.
