Abstract

Vulvar squamous cell carcinoma (SCC) is the most frequent vulvar neoplasia. While the primary role of surgery is widely accepted, large population studies are needed to compare survival between diverse treatment modalities and to identify independent prognostic factors to help council patients and guide oncological treatment. The U.S. National Cancer Index, Surveillance, Epidemiology and End Results (SEER) program data between 2000 and 2018 was screened for all squamous cell carcinoma affecting the vulva. Raw data was processed with IBM SPSS. Demographic, clinical-pathological and treatment data were studied. Overall survival (OS) was calculated using the Kaplan-Meier method and subgroups were compared using the log rank test. A multivariate cox regression was conducted to identify independent prognostic factors. A total of 11,360 patients were identified with a median age of 65. Median overall survival was 101 months. Surgery as a primary treatment is the therapeutic sequence associated with the best overall survival. Multivariate cox-regression did not meet proportional hazard assumption. Age, pathological grade, stage at diagnosis, treatment sequence and the use of chemotherapy were identified as independent prognostic factor. Surgery alone is the treatment sequence offering the best overall survival. Surgery should be offered to all eligible patients.
