Surgical Treatment of Vulvar Cancer: Follow-up
Updated: Nov 20, 2008
Outcome and Prognosis
Overall survival for patients with vulvar carcinoma is excellent, especially in those with early-stage disease. Experience with modern treatment from the Mayo clinic shows that the overall survival rate for women with vulvar carcinoma is 75%, compared to an 89% actuarial survival rate for age-matched controls. The 5-year survival rates after surgery for vulvar cancer are as follows:
- Stage I - 90%
- Stage II - 81%
- Stage III - 68%
- Stage IV - 20%
Future and Controversies
A prophylactic quadrivalent vaccine was approved by the Food and Drug Administration (FDA) in 2006 for the prevention of anogenital lesions including genital warts, vulvar and vaginal intraepithelial neoplasia, and cervical lesions associated with HPV 6, 11, 16, and 18. The first study to demonstrate the efficacy with HPV type 16 vaccine was reported by Koutsky and colleagues in 2002.27 This vaccine contained virus-like particles (VLPs) that do not contain viral DNA. Two studies were subsequently published examining the efficacy of the quadrivalent vaccine. These studies demonstrated significant vaccine efficacy in decreasing the incidence of anogenital lesions caused by HPV 6, 11, 16, and 18.28,29
In the summer of 2008, the FDA approved marketing of the quadrivalent vaccine for the prevention of vulvar and vaginal cancer.30
Based on work in breast cancer and melanoma, a sentinel lymph node (SLN) can be identified and can be predictive of patients who will have other involved nodes. The technique of SLN dissection is attractive in vulvar carcinoma since most women will have negative lymph nodes. If the sentinel node dissection proves to be sufficiently sensitive, full groin node dissection could be limited only to women with positive lymph nodes. Currently, only a few early reports document the efficacy of this technique. A sentinel node can be identified in approximately 85% of women with isosulfan blue dye and 100% with the injection of Tc-99 labeled albumin. Early reports examining the sensitivity of this technique appear promising. The GOG is currently studying the feasibility and the sensitivity of sentinel lymph node dissection in women with vulvar carcinoma.31
The combination of chemotherapy with radiation in cervical cancer has produced marked improvement in survival for locally advanced disease. This concept appears to also be effective in locally advanced vulvar carcinoma. Chemotherapy combined with radiation also may improve the cure rate in women with positive groin node findings, but acceptance of routine chemoradiation in women with positive node findings will probably require prospective evaluation.
