PurposeTo report the largest experience with brachytherapy as a conservative approach for the treatment of penile carcinoma.Methods and MaterialsWe examined the outcomes of 201 patients treated at our institution over 45 years for invasive squamous cell carcinoma of the glans penis by brachytherapy.ResultsWith a median follow-up of 10.7 years, local relapse as first failure was reported in 37 patients (18.9%), and 24 of 31 patients (77.4%) with local failure only were in complete remission after new treatment. At last follow-up 25 patients (12.4%) underwent partial surgery and 7 (3.5%) total penectomies for relapse. Fifty patients (24.8%) presented urethral stenosis requiring at least 1 dilatation, and 14 (7%) required limited surgeries for toxicities. At 5 years the estimated overall survival rate was 79% (95% confidence interval 73%-85%). The estimated original local control rate was 82% (95% confidence interval 76%-88%). Presence of inguinal lymph node metastasis and tumor size correlated with a poorer overall and disease-free survival in univariate and multivariate analyses. In univariate analysis, neutrophilia at diagnosis correlated with a higher probability of distant relapse (P=.025), and a dose ≥62 Gy correlated with better local control in N0 patients (P=.038). The risk of complication correlated with the dose, treated volume, and dose rate.ConclusionThis large institutional experience confirms the high local control achieved with brachytherapy for penile carcinoma, with the advantage of organ preservation. Most local relapses are efficiently salvaged by second-intent surgery.
