摘要: BACKGROUND AND STUDY AIMS: Endoscopic mucosal resection (EMR) of early gastric cancer is a minimally invasive procedure. The incidence and characteristics metachronous multiple cancers were investigated in retrospective study patients with after EMR treatment. PATIENTS METHODS: A total 143 who had undergone treatment periodically followed up endoscopic examinations for 24 months or longer. RESULTS: median period follow-up was 57 (range - 157 months). None the died cancer, there no treatment-related deaths. Five other diseases. Of 20 (14 %) cancers, 15 treated by EMR. One patient differentiated submucosal four undifferentiated underwent surgery. Sixteen (11 synchronous lesions within 1 year initial About half located same third stomach as primary lesion, most similar macroscopic type to lesions. Most type.
