Abstract
OBJECTIVE: To retrospectively evaluate the safety and feasibility of endoscopic submucosal dissection (ESD) for the treatment of early gastric cancer (EGC) in elderly patients ≥75 years of age. PATIENTS AND METHODS: One hundred seventy-one patients (187 lesions) treated with ESD from January 2010 to September 2013 were enrolled in our study. Subjects were classified into two groups: elderly (age ≥75 years) or non-elderly (age <75 years). Clinicopathological characteristics, resectability, curability, complications, rates of local recurrence, and residual disease were evaluated. Association of clinicopathological characteristics of the lesions with immediate bleeding was analyzed. RESULTS: No significant differences in clinical characteristics were observed. The incidences of comorbidity were significantly different between the elderly group and the non-elderly group (P<.001). Of the elderly patients, 54.3% had two or more underlying diseases compared with 18.4% of the non-elderly patients (P<.001). Of the 98.0% of elderly patients and 97.1% of younger patients who received en bloc resection, curative resection reached 94.1% and 96.3%, respectively. Immediate bleeding occurred in 15.2% of the elderly group and 4.8% of the non-elderly group (P=.044). Operation time differed significantly (P=.039). No apparent discrepancy was observed in perforation and delayed bleeding. The differences in the invasion depth were considered between the two groups (P=.001). Logistic regression analysis revealed that the rate of immediate bleeding was associated with invasion depth (P=.003). There were no differences in the follow-up period and rates of local recurrence and residual disease. CONCLUSIONS: ESD is safe and feasible for elderly patients in the era of a graying population. Higher risk of immediate bleeding and longer operation time should be concerned.
