Organ-sparing surgery of penile cancer: higher rate of local recurrence yet no impact on overall survival

Purpose To report on the oncological outcome of organ-sparing surgery (OSS) compared to (total or partial) penectomy regarding recurrence patterns and survival in squamous cell carcinoma (SCC) of the penis. Methods This was a retrospective study of all patients with penile SCC and eligible follow-up data of at least 2 years at our institution. Patients with tumors staged ≥ pT1G2 underwent invasive lymph node (LN) staging by dynamic sentinel-node biopsy or modified inguinal lymphadenectomy. Radical inguinal lymphadenectomy was performed when LNs were palpable at diagnosis and in those with a positive LN status after invasive nodal staging. Follow-up visits were assessed, and local, regional and distant recurrences were defined and analyzed. Results 55 patients were identified with a mean follow-up of 63.7 months. Surgical management was OSS in 26 patients (47.2%) and partial or total penectomy in 29 cases (52.8%). Histopathological staging was: pTis (12.7%), pTa (16.3%), pT1a (18.2%), pT1b (5.5%), pT2 (29.1%) and pT3 (18.2%), respectively. Patients in the penectomy group were significantly older (mean 68 vs. 62 years; p = 0.026) with a higher rate of advanced tumor stage (≥ pT2: 44.8% vs. 11.5%; p = 0.002). The local recurrence rate was 42.3% ( n = 11) following OSS compared to 10.3% ( n = 3) after penectomy ( p = 0.007). Kaplan–Meier curves showed no significant differences between the two groups regarding metastasis-free and overall survival. Conclusions OSS is associated with a higher local recurrence rate compared to penectomy, yet it has no negative impact on overall and metastasis-free survival.
