Most of the vulvar squamous cell carcinomas are treated mainly by surgery, supplemented by radiotherapy. Before surgery, the pathological type and depth of infiltration need to be clarified by tumor tissue biopsy. Surgical treatment includes vulvar tumor resection and inguinal lymph node dissection. Vulvar tumor resection is divided into extensive vulvectomy, modified extensive vulvectomy and enlarged vulvectomy, and inguinal lymph node dissection is divided into radical inguinal lymph node dissection, inguinal anterior lymph node dissection and inguinal lymph node biopsy. The vulva is relatively moist, and the skin mucosa has poor tolerance to radiation and poor tolerance to radiotherapy, so there is a limitation of irradiation dose, and it is difficult to reach the radical radiotherapy dose. Therefore, there is a limitation of irradiation dose and it is difficult to reach the radical radiation therapy dose. If the vulvar cancer is treated with radiotherapy alone, the efficacy is poor and the local recurrence rate is high. Therefore, radiotherapy is usually used as part of preoperative and postoperative adjuvant treatment or comprehensive treatment for advanced vulvar cancer, and it can also be used for advanced lesion reduction and improving the prognosis of vulvar cancer patients.
