    Abstract:
    PURPOSE: The only possibility of a surgical cure in patients with locally advanced primary or recurrent rectal cancer would be an extended resection such as pelvic exenteration and sacral resection. The aim of this study was to evaluate the safety, tolerability, and survival benefits of these procedures. METHODS: Between 1988 and 1999, 64 patients with locally advanced primary or recurrent rectal cancer underwent abdominoperineal resection, with sacral resection in 9 patients, anterior pelvic exenteration in 8 patients, total pelvic exenteration in 27 patients, and total pelvic exenteration with sacral resection in 20 patients. RESULTS: Rates of morbidity, reoperation, and mortality were 50, 4.5, and 0 percent in 22 patients with primary cancer, and 60, 2.4, and 2.4 percent in 42 patients with recurrent disease, respectively. Major complications, such as sepsis, intra-abdominal abscess, and enteric fistula caused one hospital death and reoperation in two patients. In 21 patients who underwent curative resection for primary cancer, the overall five-year survival rates were 74.1 percent for Dukes B and 47.4 percent for Dukes C, although the difference was not statistically significant. Thirty patients with recurrent cancer who underwent curative resection had significantly improved survival, with a five-year survival rate of 22.9 percent, compared with 12 patients who underwent palliative resection, resulting in a survival rate of 0 percent (P = 0.0065). CONCLUSIONS: Pelvic exenteration and sacral resection for primary or recurrent rectal cancer are tolerable procedures with a low mortality rate. Although they provide a survival benefit if curative resection is possible, the associated morbidity remains high and should be followed up closely.
