- Abstract
- Purpose This study is aimed to evaluate the clinical outcomes of surgical treatment for nonagenarian patients with colorectal cancer. Methods This retrospective single-center study included patients diagnosed with colorectal cancer at the age of >= 90 years between 2004 and 2018. Patient demographics were compared between the operation and nonoperation groups (NOG). Perioperative outcomes, histopathological outcomes, and postoperative complications were evaluated. Overall survival was analyzed using Kaplan-Meier methods and log-rank test. Results A total of 31 patients were included (16 men and 15 women), and the median age was 91 (range: 90-96) years. The number of patients who underwent surgery and who received nonoperative management was 20 and 11, respectively. No statistical differences in baseline demographics were observed between both groups. None of these patients were treated with perioperative chemotherapy or radiotherapy. Surgery comprised 18 (90.0%) colectomies and 2 (10.0%) transanal excisions. Short-term (<= 30 days) and long-term (31-90 days) postoperative complications occurred in 7 (35.0%) and 4 (20.0%) patients, respectively. No complications needed reoperation, such as anastomosis leakage or bleeding. No postoperative mortality occurred within 30 days: 90-day postoperative mortality occurred in two patients (10.0%), respectively. The median overall survival of the operation group was 31.6 (95% confidence interval: 26.7-36.5) and that of NOG was 12.5 months (95% CI: 2.4-22.6) (P = 0.012). Conclusion Surgical treatment can be considered in carefully selected nonagenarian patients with colorectal cancer in terms of acceptable postoperative morbidity, with better overall survival than the nonsurgical treatment.
