Abstract
AimColorectal cancer resection in the elderly may be associated with significant morbidity. This study aimed to assess perioperative morbidity in elderly patients undergoing colorectal cancer resection and to investigate risk factors for postoperative complications.Materials and MethodsConsecutive patients aged ≥ 75 years undergoing colorectal cancer resection with curative intent between January 2014 and December 2021 at our institution were included. We evaluated risk factors for postoperative complications, length of hospital stays (LOS), 30-day readmission, and 90-day mortality rates.ResultsA total of 843 patients underwent colorectal cancer resection during the study period, of whom 202 patients were 75 years or older. Advanced age was associated with postoperative complications (Clavien–Dindo score > 3b, p = 0.001). Sarcopenia, preoperative plasma albumin < 3.5 g/dL, and open and urgent surgery were significantly correlated with major complications (p = 0.015, p = 0.022, p = 0.003, and p < 0.001, respectively). LOS was longer in elderly patients with a modified 5-item Frailty Index (5-mFI) ≥ 2 and low preoperative serum albumin levels, as well as following open surgery (p = 0.006, p = 0.001 and p < 0.001, respectively). Sarcopenia and preoperative plasma albumin < 3.5 g/dL were predictors for 90-day mortality (p = 0.004 and p > 0.001).ConclusionAdvanced age, sarcopenia, preoperative hypoalbuminemia, 5-mFI ≥ 2, and open or urgent surgery may serve as predictors for postoperative morbidity in the elderly population.
