Final answer:
Immunotherapy and targeted therapy are treatment options for late-stage vulvar cancer. Palliative care can also be provided. Stem cell transplant is not typically used.
Step-by-step explanation:
To treat late-stage vulvar cancer, immunotherapy is one option that can be used. Immunotherapy attempts to stimulate the immune system to destroy cancer cells. It is usually used in conjunction with other forms of treatment, such as surgery or chemotherapy. Targeted therapy, which involves using drugs to specifically target molecules involved in cancer growth, is another possible treatment option. Palliative care can also be provided to manage symptoms and improve the patient's quality of life. Stem cell transplant, on the other hand, is not typically used as a treatment for late-stage vulvar cancer.
