[Impact of the Age-Adjusted Charlson Comorbidity Index on Postoperative Complications after Gastric Cancer Surgery].

The primary objective of this retrospective study was to examine the association between the age-adjusted Charlson comorbidity index(aCCI)score and postoperative complications after gastric cancer surgery.A total of 237 patients who underwent distal/total gastrectomy for gastric cancer between 2012 and 2020 were enrolled in this study. The aCCI and CCI were calculated by weighting individual comorbidities. The correlations between the clinicopathologic features, including CCI or aCCI, and postoperative complications were analyzed statistically.Univariate and multivariate analyses demonstrated that both the CCI- and aCCI- high classifications were significant risk factors for postoperative complications.The aCCI exhibits a suitable predictive ability for patients undergoing gastric surgery. Although patients with a CCI≤2 showed little risk, patients with an aCCI≥5 were at a high surgical risk and should receive very careful attention for postoperative complication(s).
