Abstract

Purpose
We aimed to evaluate the postoperative complications of laparoscopic colorectal cancer (CRC) surgery and the adverse events of postoperative chemotherapy in elderly patients compared to younger patients and to identify the factors influencing the termination of postoperative chemotherapy.
Methods
Between June 2015 and May 2018, 188 patients with CRC underwent laparoscopic surgery with curative intent. Patients aged ≥ 70 were defined as elderly. Postoperative complications and adverse events of chemotherapy were assessed by using the Clavien-Dindo classification and the Common Terminology Criteria for Adverse Events, respectively. The clinicopathological factors were analyzed retrospectively.
Results
Seventy-eight patients were considered elderly with a mean age of 77.5 ± 5.5 years. Overall postoperative complications occurred in 68 patients (36.2%). Age and primary tumor location were independent predictors of overall postoperative complications. Smoking history was the only independent predictor of major postoperative complications. Of 113 patients who were recommended postoperative chemotherapy, 90 patients (79.6%) received postoperative chemotherapy. Overall adverse events occurred in 40 patients (44.4%). The American Society of Anesthesiologists physical status classification and chemotherapy regimen were significantly associated with overall adverse events. The chemotherapy regimen was the only factor significantly associated with severe adverse events. Of 90 patients, postoperative chemotherapy could not be completed in 11 (12.2%). Age was the only factor significantly associated with stopping postoperative chemotherapy (P = 0.003).
Conclusion
This study shows that laparoscopic CRC surgery and postoperative chemotherapy were feasible in elderly patients. Further efforts are needed to ensure that elderly patients have the opportunity to make informed decisions regarding postoperative chemotherapy.
