Squamous vulvar cancer: a clinically based individualization of treatment

Objective: The aim of the study was to evaluate treatment results in 211 patients with previously untreated squamous cell vulvar cancer who were primary managed by surgery at the Gynecologic Oncology Unit of Alexandra Hospital, in terms of en bloc radical vulvectomy (N = 105), modified radical vulvectomy with three different incisions technique (N = 60), and radical hemivulvectomy (N = 46) with inguinofemoral lymphadenectomy.

Methods: The surgical stage of disease, nodal status, lesion location and focality, marginal status, tumor size, physical and performance status, surgical modality used, and finally complications and recurrence rates were the analyzed factors for both survival and disease remission.

Results: The overall 5-year survival was 70.1%. The 5-year survival for node-positive patients was 53.8% versus 79.7% for node-negative patients. Unifocal lesions had a 5-year survival of 76% compared with 50% of multifocal lesions. Posterolateral lesions had a better 5-year survival than that of anterior central lesions (79.5% vs 54. 4%). The marginal status of the surgical specimen was a significant predictor of both survival and recurrence. There was a significant difference in complications related to the en bloc radical vulvectomy in terms of wound breakdown, infection, and wound cellulitis.

Conclusions: Modified radical procedures are equally effective with the en bloc radical vulvectomy for the management of early (stage I/II) vulvar cancer. In advanced disease concervative surgery in an individualized approach could also effectively be applied.
