Abstract
Background
Studies regarding the long‐term outcomes of endoscopic submucosal dissection (ESD) performed in older patients with colorectal tumors are limited. Therefore, in this study, we aimed to analyze the long‐term outcomes of older patients with colorectal tumors who underwent ESD and identify prognostic factors.
Methods
The data of patients aged ≥ 75 years who underwent ESD for colorectal tumors (adenoma and Tis/T1 colorectal cancer) at a single center were retrospectively analyzed. Prognostic factors for overall survival were analyzed using the Kaplan–Meier method and the Cox proportional hazard model.
Results
Of the 156 patients included, 51 patients died during the follow‐up period, among whom two deaths were due to colorectal cancer. The univariate analysis revealed that an age ≥83 years, Charlson Comorbidity Index ≥2, prognostic nutritional index p
= 0.0008) and NLR ≥3 (hazard ratio, 1.98; 95% CI: 1.02–3.81;
p
= 0.042) as independent prognostic factors.
Conclusions
CCI and NLR may be useful parameters for decision‐making in older patients undergoing colorectal ESD.
