Low yield of residual vulvar carcinoma and dysplasia upon re-excision for close or positive margins

Academic Article


  • Objectives The objectives of this study are to determine the utility of re-excision after a primary diagnosis of vulvar carcinoma by assessing the frequency of residual carcinoma found upon re-excision and to quantitate the wound breakdown and carcinoma recurrence rates. Methods We reviewed 1122 cases of VIN or vulvar carcinoma. Women who underwent re-excisional procedures, as part of their initial surgical treatment were identified. Associations between the margin status of the original excisional sample and histology of re-excision, as well as association between the depth of invasion upon initial excision and histology of re-excision were analyzed with Chi-square tests. Results We identified 84 evaluable patients, 72 with stage I disease, 4 with stage II, and 7 with stage III disease. Upon the initial excisional procedure, 33 patients (39%) had carcinoma-positive margins, 27 patients had VIN-positive margins (32%) and 24 patients (28%) had negative margins (> 1 mm). Upon re-excision, 1/24 (4%) patients with negative margins, 2/27 (7%) patients with VIN-positive margins, and 11/33 (33%) patients with carcinoma-positive margins were found to have carcinoma in the re-excision specimens (p < 0.0001, χ2 = 31). Deeper tumor invasion of the initial excisional specimen (1-12 mm) was associated with a higher chance of finding carcinoma upon re-excision (range 18-42%, depending on depth of invasion) (p = 0.015, χ2 = 19). Nineteen patients (23%) had vulvar wound breakdown post re-excision. Twelve patients (15%) experienced recurrences. Conclusions The yield of micro- or invasive carcinoma at re-excision is low, with a high wound breakdown rate. Re-excision should be considered for patients with margins positive for carcinoma, especially for women with deep invasion, while women with VIN or close but clear margins may be followed. © 2013 Elsevier Inc.
