title: The efficacy of endoscopic mucosal resection in the diagnosis and treatment of group III gastric lesions.
abstract: BACKGROUND
  The efficacy of endoscopic mucosal resection (EMR) in diagnosing and treating group III lesions was analyzed.
  
  
  METHODS
  Forty-three patients, with group III lesions confirmed by histopathological examination of the biopsy specimens, were included. All of these patients underwent EMR. The final diagnosis after EMR broadly classified the lesions as adenocarcinoma or adenoma. The clinicopathological features and therapeutic results were analyzed.
  
  
  RESULTS
  Adenocarcinoma was identified in 16 patients (37.2%) and adenoma in 27 patients (62.8%). There were no differences in gender, age, lesion site, macroscopic type, or maximum diameter between the two groups. A significant difference in the maximum diameter of elevated lesions (p<0.05) was found between adenocarcinomas and adenomas, with the elevated lesions of adenocarcinomas measuring more than 10 mm. No residual focus recurrence was found among the adenomas.
  
  
  CONCLUSIONS
  We conclude that EMR is effective and useful in diagnosing and treating group III lesions.
