Background and AimThe existence of other primary tumors during the treatment and management of gastric cancer (GC) is an important issue. The present study investigated the prevalence and management of synchronous colorectal neoplasms (CRN) in surgically treated GC patients. MethodsOf 381 surgically treated GC patients, 332 (87.1%) underwent colonoscopy to detect CRN before surgery or within a year after surgery. ResultsCRN were synchronously observed in 140 patients (42.2%). Adenoma was observed in 131 patients (39.4%). Endoscopic resection was done in 18 patients with adenoma. Colorectal cancer (CRC) was observed in 16 patients (4.8%), superficial CRC in 13 and advanced CRC in three patients. Endoscopicresection of superficial CRC was carried out in seven patients, whereas simultaneous surgical resection of CRC was done in nine patients. CRN were more frequently observed in men. CRC was more frequently observed in GC patients with distant metastasis, albeit without significance. The overall survival of GC patients with CRN or CRC was poorer than that of patients without CRN or CRC. ConclusionSynchronous CRN were commonly associated with GC and screening colonoscopy should be offered to patients with GC.
