    Abstract:
    OBJECTIVES: Endoscopic submucosal dissection (ESD) has advantages over conventional endoscopic mucosa resection. The number of elderly patients (more than 75 years old) with early gastric cancer (EGC) has been steadily increasing. We sought to assess clinical outcomes of ESD for EGC in elderly. METHODS: ESD was performed for patients with EGC, who fulfilled the criteria for ESD: mucosal cancer without ulcer findings irrespective of tumor size; mucosal cancer with ulcer findings 3 cm or less in diameter; and minute submucosal invasive cancer 3 cm or less in size. Two hundred and sixty elderly patients (> or =75 years old) with 279 lesions, and 401 non-elderly patients with 434 lesions were enrolled to this study. The patients underwent ESD and then received periodic endoscopic follow-up and metastatic surveys for 6-89 months (median: 30 months). Resectability (en-bloc or piecemeal resection), curability (curative or noncurative resection), completeness (complete or incomplete resection), complications, and survival rates were assessed. RESULTS: The one-piece resection rate was significantly lower in elderly patients (93.9%) than in non-elderly patients (97.9%). The complete resection rate was significantly lower in elderly patients (87.4%) than in non-elderly patients (96.6%). Pneumonia, but not bleeding or perforation, developed in association with ESD more frequently in the elderly patients by 2.2%. Local tumor recurrence was quite rare, and the overall and disease-free survival rates were acceptable irrespective of age. CONCLUSION: En-bloc and complete resections were achieved less frequently in elderly patients, but the long-term outcomes in elderly EGC patients may be excellent, and ESD is a feasible treatment in the elderly.
