Abstract:

Objective Meta-analysis was applied to comprehensively review published studies on sporadic duodenal neoplasm (SDN) and colorectal neoplasm (CRN, mainly including colorectal adenoma and colorectal cancer). Methods Fifteen documents (14 case-control studies +1 cross-sectional study) satisfying the inclusion criteria were subject to meta analysis with Review Manager 5.3 software, OR value and 95% C I were selected as meta-analysis indicators, and inverted funnel plot was developed to test the heterogeneity of results and calculate combined effect values. Results A total sample size of 205 959 including 1 286 cases in the case group and 204 673 cases in the control group were included. Moderate heterogeneity ( I 2=44%, P=0.03) was considered in the results of case-control studies through meta-analysis, and subgroup analysis showed that the site of SDN occurrence may be a potential source of heterogeneity in studies. The results of grouping according to different outcomes showed that SDN increased the onset risk of CRN at all stages (colorectal adenoma O R=2.29, 95% C I=1.74-3.02; colorectal cancer O R=2.87, 95% C I=1.96-4.02; advanced adenoma O R=2.83, 95% C I=2.27-3.53; advanced neoplasm O R=3.60, 95% C I=2.14-6.07).The grouping was made according to the different sites and number of CRN, the results showed that multiple tumors in left colon was certainly related to SDN ( O R=1.37, 95% C I=1.16-1.62; O R=9.30, 95% C I=1.41-61.44). Conclusion The risks of various CRN in SDN patients will increase, especially, it is more significantly correlated with advanced and multiple CRN lesions located in the left colon.
