Abstract

From 1980 to 1988, 101 patients underwent radical nephrectomy for renal cell carcinoma. Among them, extensive lymphadenectomy was done in 47 patients, and not in the rest of patients. According to cellular grade, tumor size. cell type and stage, survival rates of the two groups were compared. Survival rate of the renal cell carcinoma was decreased in high grade, large size and non-clear cell type, and so they correlated with prognosis. No difference of survival rate was found between extensive lymphadenectomized patients and non-extensive lymphadenectomized patients according to these prognostic factors. Also, no difference or survival rate `in each stage was found between above two groups. An extensive lymphadenectomy is unlikely to increase survival, but we have difficulty in compare the two groups because cases of this study is limited and nodal metastasis can not be confirmed in non-extensive lymphadenectomized patients. Therefore, more randomized controlled study must be performed for accurate result.
