title: Chemoradiation as primary or adjuvant treatment for locally advanced carcinoma of the vulva.
abstract: OBJECTIVE
  To determine the impact of primary or adjuvant chemotherapy and radiation (CRT) on the survival rates of patients with locally advanced vulvar carcinoma.
  
  
  METHODS
  Between 1973 and 1998, 54 patients with vulvar cancer were treated with radiation therapy, among which 20 received CRT, while 34 patients received radiation therapy (RT) alone. Of the 20 patients, 14 were treated for primary or recurrent disease (pCRT), and 6 after radical vulvectomy for high-risk disease (aCRT). Of the 34 patients, 12 were treated primarily (pRT) and 22 received adjuvant treatment (aRT). Chemotherapy consisted of 2 courses of 5-fluorouracil (5-FU) and mitomycin C administered during RT. Six patients received cisplatin in place of mitomycin C. In CRT groups, radiation was administered to the vulva, pelvic, and inguinal lymph nodes to a median dose of 45 Gy with additional 6-17 Gy to gross disease. In RT groups, the median dose to the microscopic diseases was 45 Gy. Nine patients received external beam boost and 16 patients received supplementary brachytherapy in the forms of (226)Ra or (241)Am plaques to sites of macroscopic disease.
  
  
  RESULTS
  Overall survival was superior in the patients treated with pCRT versus pRT with statistical significance (p = 0.04). There was also a statistically significant improvement in disease-specific (p = 0.03) and relapse-free survival (p = 0.01) favoring pCRT. No statistically significant trends of improved survival rates favoring aCRT over aRT were observed.
  
  
  CONCLUSIONS
  Concurrent radiation therapy and chemotherapy decreases local relapse rate, improves disease-specific and overall survival over RT alone as primary treatment for locally advanced vulvar cancer.
