Logistic regression analysis showed that old age, being male, having a family history of cancer, being located in the upper third of the stomach, and early T stage tumors were risk factors for MGC. Missed lesions were detected in 95 of the 322 MGC patients, and the risk factor for missed lesions was large\u2010sized main lesion. Fifty\u2010four of the 322 MGC patients had early gastric cancer in the upper third of the stomach, and 37.0% of those tumors were candidates for endoscopic submucosal dissection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Physicians should keep pretreatment risk factors for MGC in mind to avoid missing a synchronous lesion.
