Between 1960 and 1987, 414 patients with invasive squamous cell carcinoma of the penis were referred to the Brazilian National Cancer Institute. Inguinal metastases were demonstrated by lymphadenectomy in 39% of the 23 patients with stage N0, 49% of 92 with stages N1 and N2, and 100% of 18 with stage N3 disease. We analyzed the followup of 350 patients who underwent surgical treatment. In 224 patients (64%) amputation or some form of penile surgery was done initially, while 102 (29%) underwent amputation and lymphadenectomy, and 24 (7%) underwent palliative surgery for advanced squamous cell carcinoma. The statistics revealed a better 5-year survival rate for the patients who underwent lymphadenectomy concomitantly with penile surgery compared to those who underwent delayed lymphadenectomy (p < 0.001). Patients in whom systematic lymphadenectomy was negative had a better prognosis than those with positive systematic lymphadenectomy results (p < 0.001). The latter patients had a better prognosis compared with those in whom delayed lymphadenectomy was positive (p = 0.0103). Patients with well and moderately differentiated carcinoma had a higher survival rate at 5 years than did those with poorly differentiated carcinoma (p < 0.001 and p = 0.003, respectively). All deaths from metastatic disease occurred within 24 months among the patients who underwent systematic lymphadenectomy and within 5 years after simple penile surgery. In the short term, surgical debulking combined with reconstruction techniques allowed for improved quality of life in patients with advanced local-regional disease.
