Abstract:
Objective:To explore the correlation between preoperative nutritional status and postoperative complications in elderly patients with right-sided colon cancer.Methods:A prospective registry database of 1, 196 patients undergoing curative surgery for right-sided colon cancer was collected from 52 top-tier hospitals nationwide between September 2021 and June 2022. The cohort included 627 males and 569 females, with an age range of 64(53, 71) years. Among these, 136 patients developed complications, while 1, 060 did not. Patients were divided into two groups based on age: the elderly group(≥65 years, n=571) and the middle-aged group(<65 years, n=625). Preoperative nutritional assessment indicators, clinical pathological data, and the incidence of complications within 30 days post-surgery were collected. For normally distributed quantitative data, mean ± standard deviation( ± s) was used, and the t-test was applied for intergroup comparisons. Non-normally distributed quantitative data were represented as M( Q1, Q3) and analyzed using the Wilcoxon rank-sum test; categorical data were compared using the chi-square test or Fisher′s exact test. In the analysis of risk factors for postoperative complications in elderly patients, univariate analysis was first conducted on all potential risk factors, followed by the inclusion of statistically significant variables from univariate regression into a multivariate logistic regression model. Results:The overall incidence of postoperative complications was 11.37%(136/1 196), with common complications includin wound infection(2.26%), intestinal obstruction (2.26%), anastomotic leakage(1.42%), deep vein thrombosis(1.42%), and chylous leakage(1.42%). In the elderly group, the proportion of patients with preoperative nutritional risk who developed complications was significantly higher than those without complications(66.20% vs. 53.40%, P=0.043). In the multivariate analysis, body mass index( OR=1.058, 95% CI: 1.005-1.117, P=0.031) and nutritional risk( OR=1.803, 95% CI: 1.066-3.126, P=0.031) were identified as independent risk factors for postoperative complications in elderly patients. Conclusions:There is a correlation between preoperative nutritional status and the occurrence of postoperative complications in elderly colon cancer patients, particularly with respect to body mass index and nutritional risk. These findings underscore the importance of preoperative nutritional assessment and intervention in elderly patients to reduce the risk of postoperative complications.
