Abstract:
Objective:To investigate the diagnosis and treatment principles of multiple primary colorectal carcinoma(MPCC).Methods:A retrospective analysis was made on 63 patients with MPCC admitted from January 1993 to January 2007 in our hospital. Results:The incidence of MPCC was 2.1%(63/3 021) with 31 cases being synchronous carcinoma(SC) and 32 cases diagnosed as metachronous carcinoma(MC). Male to female ratio was 2.5:1.Most tumors were located in rectum and sigmoid colon.A total of 34 cases(54.0%) were diagnosed by fiberoptic colonoscopy before operation.The diagnosis rate of SC by fiberoptic colonoscopy before operation and during operative exploration were all 38.7%(12 cases). The diagnosis rate of MC by fiberoptic colonoscopy before operation and during operative exploration were 68.7%(22 cases) and 6.25%(2 cases) respectively.The overall 5-year survival rate of the patients in SC was 45%(9/20),the overall 5-year survival rate of the patients in MC after the first operation was 72.4%(21/29). Conclusion:Clinician should improve the recognition of MPCC.Patients with colorectal carcinoma should undergo routine fibercolonscopy and standard radical excision. Periodic follow-up for the high-risk group should be highlighted.
