Predictors for long‐term survival after interdisciplinary salvage surgery for advanced or recurrent gynecologic cancers

Abstract

We wanted to identify factors which allow predicting long-term survival after pelvic exenteration (PE) for locally advanced or recurrent gynecologic malignancies. All patients undergoing PE at our institution from 1983 to 2002 were screened. In 203 cases data were obtainable and analyzed with respect to factors predicting outcome considering morbidity, mortality, and survival. Follow-up data and data concerning late complications not documented in our records were obtained by telephone interviews. Mean age was 55 (22-77) years. PE was performed for locally advanced (36%) or recurrent (64%) cervical (n = 133), endometrial (n = 26), vaginal (n = 23), vulvar (n = 10), and ovarian cancer (n = 11, cases with rectum and/or bladder resections). In 13.4% (n = 26) the intent of the procedure was palliation in the remaining cure. Procedures performed were anterior (n = 91), posterior (45), or total (n = 67) PE. 53% of patients underwent preoperative radio-chemotherapy, 11.8% as a neoadjuvant treatment. Mean OR time was 8.1 hr, an average of 5.6 units of packed red blood cells were perioperatively transfused. Microscopically complete resection was achievable in n = 69 patients. Perioperative mortality was 1% (n = 2). Seventy-one percent (n = 144) of patients were available for follow-up. Five-year overall survival in patients treated with a curative intent was 21%, 5-year survival in those patients with complete resection was 32%. Forty-two percent of patients with a complete resection without lymph node involvement, age 30-50, curative intention, and the absence of a pelvic sidewall infiltration survived 5 years or longer. In our series a 5-year survival rate of over 40% could be achieved for nodal-negative patients without pelvic sidewall infiltration when treated with curative intent and after complete resection.
