Vulvar cancer is a type of malignant tumor in the female reproductive system, commonly occurring in postmenopausal elderly women. The disease progresses to involve lymph node metastasis, and its clinical staging is either stage III or stage IV. If the disease spreads to the inguinal lymph nodes with no other site affected, then the clinical stage is considered stage III. If the vulvar cancer metastasizes to the pelvic lymph nodes, or distant locations such as the liver, lungs, or bones, then it is classified as stage IV. For cases of stage III and IV vulvar cancer, the main treatment methods are palliative surgery, radiation therapy, and chemotherapy. The treatment strategy primarily involves a combination of surgery and radiation therapy along with chemotherapy. For patients with stage III and IV vulvar cancer, the prognosis is generally poor.
