RESUMO
The need for pelvic treatment in patients with node-positive vulvar cancer (VSCC) and the value of pelvic lymphadenectomy (LAE) as a staging procedure to plan adjuvant radiotherapy (RT) is controversial. In this retrospective, multicenter analysis, 306 patients with primary node-positive VSCC treated at 33 gynecologic oncology centers in Germany between 2017 and 2019 were analyzed. All patients received surgical staging of the groins; nodal status was as follows: 23.9% (73/306) pN1a, 23.5% (72/306) pN1b, 20.4% (62/306) pN2a/b, and 31.9% (97/306) pN2c/pN3. A total of 35.6% (109/306) received pelvic LAE; pelvic nodal involvement was observed in 18.5%. None of the patients with nodal status pN1a or pN1b and pelvic LAE showed pelvic nodal involvement. Taking only patients with nodal status ≥pN2a into account, the rate of pelvic involvement was 25%. In total, adjuvant RT was applied in 64.4% (197/306). Only half of the pelvic node-positive (N+) patients received adjuvant RT to the pelvis (50%, 10/20 patients); 41.9% (122/291 patients) experienced recurrent disease or died. In patients with histologically-confirmed pelvic metastases after LAE, distant recurrences were most frequently observed (7/20 recurrences). Conclusions: A relevant risk regarding pelvic nodal involvement was observed from nodal status pN2a and higher. Our data support the omission of pelvic treatment in patients with nodal status pN1a and pN1b.
RESUMO
INTRODUCTION: Younger women are particularly affected by the increase in the incidence of vulvar cancer. The purpose of this study was to investigate how clinical characteristics differ depending on the patient´s age and what role the age of initial diagnosis plays in the prognosis. Patients andMethods: Included patients were divided into groups aged below or above 50 years. The disease-free survival (DFS) was calculated and a multivariate discriminant analysis was conducted. RESULTS: Of the 300 patients, 79 were ≤50 years and 221 were >50 years. The median age was 64 years (19-96 years). There were no differences between the groups regarding lymph node (LN) status and distant metastasis, but T1 tumours were more frequent in patients ≤50 years (77% vs. 62%, p = 0.02). The DFS only differed between the groups when there were no LN metastases. The nodal status was the predominant prognostic factor for the DFS regardless of age. In node-free patients, the 5-year DFS was 49% for the ≤50 years group and 89% for the >50 years group (p = 0.008), whereas there was no difference if a LN was involved. CONCLUSION: In node-free patients, the risk for recurrence is lower for patients older than 50 years.
