Old and new perspectives in the management of high-risk, locally advanced or recurrent, and metastatic vulvar cancer

During the last decades there has been a continuing evolution in the surgical approach of squamous cell carcinoma of the vulva that has been traditionally treated with radical vulvectomy and bilateral inguinal-femoral lymphadenectomy. Patients with T1 tumour are usually treated with radical local excision, if the lesion is unifocal and the remainder of the vulva is normal. Patients with T1a disease have no risk of groin metastases and do not need lymphadenectomy, whereas those with T1b disease need ipsilateral inguinal-femoral lymphadenectomy if the lesion is lateral, and bilateral lymphadenectomy if the lesion is midline. Modifications of the surgical technique of deep femoral lymphadenectomy and the mapping of sentinel node can offer new interesting therapeutic perspectives. Postoperative adjuvant pelvic and groin irradiation is warranted for patients with two or more or macroscopically involved groin nodes. Locally advanced squamous cell carcinoma of the vulva has been long surgically treated with en-block radical vulvectomy and bilateral inguinal-femoral lymphadenectomy plus partial resection of urethra, vagina or anum, or by exenteration, with severe postsurgical complications, poor quality of life, and unsatisfactory survival rates. 5-Fluorouracil [5-FU] or 5-FU- and cisplatin-based chemotherapy concurrent with irradiation followed by tailored surgery represents an attractive therapeutic option for advanced disease, planned to avoid such ultra-radical surgical procedures and, hopefully, to improve patient outcome. Chemotherapy has also been used in neoadjuvant setting, with contrasting and generally unsatisfactory results, and in palliative treatment of patients with distant metastases. Surgery is the primary treatment also for vulvar malignancies other than squamous cell carcinoma, whereas the clinical usefulness of adjuvant irradiation or chemotherapy is still to be defined. Primary chemoradiation can be also used for advanced carcinoma of the Bartholin gland or for advanced adenocarcinoma associated with extramammary Paget's disease. The drugs used for chemotherapy of metastatic melanomas or sarcomas of the vulva are the same employed for the melanomas or sarcomas developed in other sites. (c) 2006 Elsevier Ireland Ltd.
