Molecular pathological epidemiology(MPE) is a multidisciplinary and transdisciplinary study field,which has emerged as an integrated approach of molecular patho-logy and epidemiology,and investigates the relationship between exogenous and endogenous exposure factors,tumor molecular signatures,and tumor initiation,progression,and response to treatment.Molecular epidemiology broadly encompasses MPE and conventional-type molecular epidemiology.Hepatocellular carcinoma(HCC) is the third most common cause of cancer-associated death worldwide and remains as a major public health challenge.Over the past few decades,a number of epidemiological studies have demonstrated that diabetes mellitus(DM) is an established independent risk factor for HCC.However,how DM affects the occurrence and development of HCC remains as yet unclearly understood.MPE may be a promising approach to investigate the molecular mechanisms of carcinogenesis of DM in HCC,and provide some useful insights for this pathological process,although a few challenges must be overcome.This review highlights the recent advances in this field,including:(1) introduction of MPE;(2) HCC,risk factors,and DM as an established independent risk factor for HCC;(3) molecular pathology,molecular epidemiology,and MPE in DM and HCC;and(4) MPE studies in DM and risk of HCC.More MPE studies are expected to be performed in future and I believe that this field can provide some very important insights on the molecular mechanisms,diagnosis,personalized prevention and treatment for DM and risk of HCC.
