Abstract
AIM: Diabetes mellitus (DM) is thought to be associated with an increased risk of non-Hodgkin's lymphoma (NHL), although the evidence so far remains inconsistent. Thus, our study aimed to further assess this association. METHODS: Electronic searches were performed of the PubMed, Web of Science and Embase databases up to 11 March 2019. A random-effects model was used to calculate summary relative risks (RRs) with corresponding 95% confidence intervals (CIs). RESULTS: A total of 20 articles including data from 35 cohort studies matched our inclusion criteria, and 31 RRs were calculated for type 2 DM; the summary RR was 1.20 (95% CI: 1.12-1.30, I2 = 84.7%). Also, four RRs were calculated for type 1 DM, and the result was significant (RR: 1.55, 95% CI: 1.15-2.08, I2 = 0.0%). The results of subgroup analyses demonstrated that the association between DM and NHL was much more substantial in an Asian population, while sensitivity analyses suggested the robustness of a positive association between DM and NHL risk. In addition, the RR of NHL correlated negatively with duration of DM, with the highest risk found in patients within 1-2 years of DM diagnosis. CONCLUSION: Our study findings suggest a moderate increase in risk of NHL in type 1 and 2 DM patients. Future studies should investigate the effects of duration of DM and antidiabetes interventions on NHL risk.
