Correlation between the extent of nodal involvement and survival following groin dissection for carcinoma of the penis.

Between 1962 and 1986, 208 inguinal and 143 ilio-inguinal lymphadenectomies were performed on 201 patients with carcinoma of the penis. The crude 5-year survival rate was 95% for patients with negative nodes, 76% when only inguinal nodes were positive, and 0% when the pelvic nodes were positive. The adverse prognostic factors were (1) involvement of > 3 inguinal nodes, (2) perinodal infiltration in the inguinal area, and (3) pelvic node involvement.
