Y1 - 2015 N1 - T2 - Gynecologic Oncology: Clinical Practice and Surgical Atlas AB - Primary vaginal cancer is an uncommon gynecologic malignancy and constitutes only 1% to 2% of gynecologic malignancies. Because of its rarity, there are specific guidelines for the diagnosis of primary vaginal cancer. A malignancy located in the vagina and not involving any adjacent pelvic organs is considered to be a primary vaginal cancer. If the malignancy extends to the cervix or vulva, it is considered a primary lesion of the nonvaginal site. Based on the observation that 95% of patients with recurrent cervical cancer will experience relapse within 5 years, all squamous cell carcinomas identified in the vagina within this period are defined as recurrences. Only those squamous cell carcinomas found more than 5 years after the diagnosis of cervical cancer are defined as primary vaginal cancers.1 If there is a history of endometrial cancer, a diagnosis of adenocarcinoma in the vagina is usually considered a recurrence regardless of the time from primary treatment.
