Vulvar cancer is a cancer of the vulva, the outer portion of the female genitals.[1] It most commonly affects the labia majora.[1] Less often, the labia minora, clitoris, or Bartholin's glands are affected.[1] Symptoms include a lump, itchiness, changes in the skin, or bleeding from the vulva.[1]
Risk factors include vulvar intraepithelial neoplasia (VIN), HPV infection, genital warts, smoking, and many sexual partners.[1][3] Most vulvar cancers are squamous cell cancers.[4] Other types include adenocarcinoma, melanoma, sarcoma, and basal cell carcinoma.[3] Diagnosis is suspected based on physical examination and confirmed by tissue biopsy.[1] Routine screening is not recommended.[3]
Prevention may include HPV vaccination.[5] Standard treatments may include surgery, radiation therapy, chemotherapy, and biologic therapy.[1] Vulvar cancer newly affected about 44,200 people and resulted in 15,200 deaths globally in 2018.[6] In the United States, it newly occurred in about 6,070 people with 1,280 deaths a year.[2] Onset is typically after the age of 45.[2] The five-year survival rate for vulvar cancer is around 71% as of 2015.[2] Outcomes, however, are affected by whether spread has occurred to lymph nodes.[4]
