Abstract: | OBJECTIVES: To determine the importance of margin status and other prognostic factors associated with the recurrence and survival of patients with squamous cell vulvar carcinoma. METHODS: Data were analyzed using Kaplan-Meier methods and Cox proportional hazards regression. All slides were re-reviewed by two gynecologic pathologists. RESULTS: Ninety patients (median age: 69) were treated for vulvar carcinoma from 1984 to 2002, including 28 FIGO stage I, 20 stage II, 26 stage III and 16 with stage IV disease. Sixty-three (70%) patients underwent complete radical vulvectomies and 27 (30%) had modified radical vulvectomies. Nineteen (20%) patients received adjuvant radiotherapy. Five-year disease-specific survival rates were 100%, 100%, 86% and 29% for stages I-IV, respectively. None of the 30 patients with a pathologic margin distance >8 mm had local recurrence. Of the 53 women with tumor-free pathologic margin of <8 mm, 12 (23%) had a local recurrence. Moreover, women with >2 positive groin nodes had significantly higher recurrence risk compared to those with <2 metastatic groin nodes (p<0.001). On multivariate analysis, positive groin nodes and margin distance were important prognostic factors for recurrence. Moreover, stage, tumor size, margin distance, and depth of invasion were significant independent predictors for disease-specific survival. The median follow-up was 58 months (range: 2-188). CONCLUSIONS: Pathologic margin distance is an important predictor of local vulvar recurrence. Our data suggest that a > or =8-mm pathologic margin clearance leads to a high rate of loco-regional control. |
