Résumé
The aim of the study was to assess the survival rates and surgery-related toxicity in patients with locally advanced squamous cell vulvar cancer (LAVC) managed by upfront chemoradiation (CRT) with/without following by surgery. CRT is the primary treatment for patients with unresectable locally advanced squamous cell vulvar carcinoma (LAVC), followed by surgery in case of residual tumor. Patients with AJCC stage II-IV squamous cell vulvar carcinoma referred to Gynecologic Oncology Unit at Fondazione Policlinico Universitario Agostino Gemelli I.R.C.C.S. from January 2016 to February 2023, managed by upfront CRT, were included. 63 patients were included, 21 (33 %) had complete response (cCR) to CRT, 26 (41 %) had partial response (cPR), 1 (2 %) stable disease (cSD), 15 (24 %) had disease progression (cPD). In the whole population, cPR/SD and cPD were associated with reduced PFS (p < 0.001) and overall survival (OS) (p < 0.001), p16 expression was associated with improved PFS (p < 0.001) and OS (p = 0.001). Among patients with clinical residual disease after CRT, 23 patients undergoing surgery experienced improved PFS (p = 0.003) and OS (p = 0.003) compared to those receiving other treatments. Eight (35 %) patients experienced severe (grade ≥ III) postoperative complications; vulvar and groin wound dehiscence/infection were the most common complications; one (4 %) patient died in the postoperative. Patients with pathological residual disease experienced worse PFS (p = 0.013) and OS (p = 0.034). Clinical response to CRT and p16 expression strongly predict survival in LAVC. Surgery for residual disease might be associated with improved survival but is burdened by high rates of complications. Pathologic residual disease correlates with high recurrence rates and poor survival.
