Surgical outcomes for colorectal cancer patients including the elderly

The aim of this study was to compare the short- and long-term outcome of older and younger colorectal cancer patients resected for cure.

Three hundred and forty-six consecutive colorectal cancer patients who underwent some form of surgery were analyzed. One hundred and forty-four patients were < 65 years old (group 1), 151 patients were 65-79 years old (group 2), and 51 patients were 80 years or more (group 3).

The overall perioperative mortality rate was 1.7% (n = 6). The median length of hospital stay was 19 days (range: 3-86 days). By univariate analysis, intraoperative bleeding (500 mL or more) (P = 0.009), duration of operations (240 min or more) (P = 0.03), and the presence of rectal cancer (P = 0.001), were strongly associated with higher incidence of postoperative complications. In multiple logistic regression analysis, only rectal cancer (P = 0.02) was significantly associated with serious postoperative complications. No age-related difference was noted concerning 5-year cancer-specific survival rates for patients with < 65, 65-79, and > or = 80 years who underwent surgery for cure (85%, 76%, and 69%, respectively) (P = 0.3). Using logistic regression analysis, tumor stage (P = 0.0001) and perioperative blood transfusions (500 mL or more) (P = 0.05) were strongly associated with outcome.

Colorectal curative surgery for malignancy can be performed safely in the elderly with acceptable morbidity and mortality rates and long-term survival.
