Stage II Vulvar Cancer
(Refer to the Treatment Option Overview section of this summary for a more detailed discussion of the roles of surgery, node dissection, and radiation therapy.)
Standard treatment options:
- Radical local excision with bilateral inguinal node and femoral node dissection with a resection margin of at least 1 cm. Radical local excision with a margin of at least 1 cm has generally replaced radical vulvectomy, and separate incision has replaced en bloc inguinal node dissection. Large T2 tumors may require modified radical or radical vulvectomy. Adjuvant local radiation therapy may be indicated for surgical margins smaller than 8 mm, capillary-lymphatic space invasion, and thickness greater than 5 mm.[4,5]
- Radical excision and sentinel node dissection, reserving groin dissection for those with metastasis to the sentinel node(s).
- Some investigators recommend radical excision and groin nodal radiation therapy as a means to avoid the morbidity of lymph node dissection. However, radiation therapy may not achieve the same local control rates or survival rates as lymph node dissection in early-stage disease. A randomized trial to address this issue in patients with clinically localized vulvar disease was stopped early as a result of early emergence of worse outcomes in the radiation therapy group.[7,8] (Refer to the Role of Radiation Therapy section in this summary for more information.)
- For those few patients unable to tolerate radical surgery or deemed unsuitable for surgery because of site or extent of disease, radical radiation therapy may be associated with favorable survival.[9-12]
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with stage II vulvar cancer. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.References
