BACKGROUND Dermatologic adverse events(DAEs)are associated with a better outcome in patients with hepatocellular carcinoma(HCC)irrespective of the therapeutic agent *** exact mechanisms associated with the development of DAEs are unknown although several studies point to direct toxicity of tyrosine kinase inhibitors(TKIs)to the skin or an immune-mediated reaction triggered by the oncologic *** is the case in other conditions,individual genetic variants may partially explain a higher risk of *** To evaluate the contribution of several gene variants to the risk of developing DAEs in HCC patients treated with *** We first analyzed 27 single-nucleotide polymorphisms(SNPs)from 12 genes selected as potential predictors of adverse event(AE)development in HCC patients treated with sorafenib[Barcelona Clinic Liver Cancer 1(BCLC1)cohort].Three additional cohorts were analyzed for AGT1(rs699)and AGT2(rs4762)polymorphisms-initially identified as predictors of DAEs:BCLC2(n=79),Northern Italy(n=221)and Naples(n=69)cohorts,*** relation between SNPs and DAEs and death were assessed by univariate and multivariate Cox regression models,and presented with hazard ratios and their 95%confidence intervals(95%CI).RESULTS The BCLC1 cohort showed that patients with arterial hypertension(AHT)(HR=1.61;P value=0.007)and/or AGT SNPs had an increased risk of ***,AGT2(rs4762)AA genotype was found to be linked to a statistically significant increased probability of DAEs(HR=5.97;P value=0.0201,AA vs GG)in the Northern Italy cohort by multivariate analysis adjusted for BCLC stage,ECOG-PS,diabetes and *** value of this genetic marker was externally validated in the cohort combining the BCLC1,BCLC2 and Naples cohorts[HR=3.12(95%CI:1.2-8.14),P value=0.0199,AGT2(rs4762)AA vs AG genotype and HR=2.73(95%CI:1.18-6.32)P value=0.0188,AGT2(rs4762)AA vs GG genotype].None of the other gene variants tested were found to be associated with the risk of D

Colorectal cancer （CRC） is one of the most common neoplasms and an important cause of mortality worldwide （http：//globocan. ***]）. Approximately 35% of the variation in CRC susceptibility is likely due to heritable factors （Lichtenstein et al., 2000}. Genetic variations in the human genome include single nucleotide variants （SNVs）, short insertions and deletions, and larger structural variants resulting in gain or loss of genomic DNA larger than 1 kb, such as copy number variants （CNVs）. Leaving aside the importance of CNVs in sporadic tumor development, these variants can also be present in the germline DNA of healthy individuals from the general population and be considered polymorphic.
