Abstract

Objectives and methods: Vulvar carcinomas are rare genital malignancies. While advanced primary cancer chemoradiation is often preferred over pelvic exenteration (PE), PE is often the only therapy available in cases of recurrence. In a retrospective study, we analyzed predictive factors and outcomes of patients who underwent exenteration for vulvar cancer in our department during the past 10 years.

Results: We identified 27 patients; 9 of them suffered from primary disease, and 18 had experienced a recurrence. A total of 18 patients presented with stage FIGO III, and 9 patients presented with stage IV. In 10 patients, the disease had spread to the inguinal lymph nodes, and in 3 patients, it had also spread to the pelvic nodes. At the end of surgery, all patients were macroscopically tumor free, which was confirmed microscopically in 20 patients (74%, R0), with the other 7 patients having microscopic tumor remnants. For all patients, median time of survival was 37 months, the five-year survival rate (5YSR) was 62%, and the overall survival (OS) was 59%. Patients with tumor-free lymph nodes had an OS of 76% and a 5YSR of 83% vs. 40% and 36%, respectively, for patients with tumorous spread to the nodes (p=0.03). The 5YSR correlated to the degree of resection (R0 vs. R1, 74% vs. 21%, p=0.01).

Conclusion: PE is a therapeutic option in advanced primary or relapsed vulvar carcinoma, offering median- to long-term survival for many patients. Carcinomatous spread to regional lymph nodes and complete resection are the most important prognostic factors.
