Abstract

Background: Although vulvar Paget's Disease (VPD) is a rare skin cancer associated with an excellent prognosis, high recurrence rates are associated with impaired quality of life. Objectives: Our objective was to investigate the epidemiological and clinical features of VPD diagnosed in a French administrative area (Franche Comte). Methods: This retrospective study investigated clinical, histologic, therapeutic and follow-up data of patients with VPD diagnosed between 1981 and 2021, including data from the Doubs cancer registry. Results: Among the 21 patients included (19 intra-epithelial and 2 invasive VPD), the median time to diagnosis was 24 months [0-110 months], with a median age of 72 years [38-88 years]. An associated cancer was present in 6 patients (29 %). At 5 years of follow-up, the recurrence rate was 26 %, but then increased to 42 % after a median follow-up of 145 months [31-503 months]. Among the 14 patients first surgically treated, incomplete resection (positive margins) was observed in all patients (100 %), associated with a postoperative recurrence rate of 86 % which was much higher than the rate observed in patients first topically treated (20 %). Postoperative adjuvant therapy (surgical revision, laser, imiquimod) significantly increased the recurrence-free survival (p < 0.001). Conclusions: Postoperative recurrence of VPD is frequent, mainly after 5 years, proving the importance of prolonged follow-up. Recurrence-free survival was significantly higher after postoperative adjuvant treatment.
