Independent and joint results of way of life, human leukocyte antigen polymorphisms on sex-specific most cancers threat: findings from the UK Biobank

Abstract

Introduction: Immune genetic variation and way of life components collectively affect most cancers susceptibility, however their interactions in most cancers growth stay unclear. We evaluated the impartial and joint results of way of life profiles and classical HLA alleles on general and site-specific most cancers dangers utilizing sex-stratified analyses in a sex-specific method. Methods: Among 159,744 males and 175,037 ladies of European ancestry within the UK Biobank, 50 frequent HLA alleles from 11 classical HLA genes have been imputed. A wholesome way of life index incorporating weight loss plan, smoking, alcohol consumption, bodily exercise, and adiposity labeled individuals into favorable, intermediate, or poor way of life classes. Independent results of HLA polymorphisms and way of life components on most cancers threat have been assessed utilizing logistic regression and Cox proportional hazards fashions, respectively. Additive and multiplicative interactions have been evaluated for cancers related to each way of life and HLA alleles utilizing Cox mannequin. Results: During a median follow-up of 13 years, 35,132 incident cancers occurred. Poor way of life elevated general most cancers threat by 38% in males and 44% in ladies. Several HLA alleles have been related to lung, prostate, and non-Hodgkin lymphoma dangers in males and kidney and endometrial most cancers dangers in ladies. Significant additive interactions have been noticed between poor way of life and a cluster of AH8.1-related HLA alleles (HLA-B*08:01, DQA1*05:01, DQB1*02:01, and or DRB1*03:01) for lung most cancers in males (relative extra threat on account of interplay (RERI)=2.63–3.24), and between poor way of life and HLA-A*24:02 for kidney most cancers in ladies (RERI=3.24, 95percentCI=1.20–5.28). Discussion: In sex-stratified analyses, unhealthy life markedly amplified lung most cancers threat in males and kidney most cancers threat in ladies amongst carriers of particular HLA threat alleles. HLA-risk-allele carriers present sex-specific vulnerability in most cancers threat, with unhealthy life markedly amplifying lung most cancers threat in males and kidney most cancers threat in ladies. These findings warrant impartial replication, notably in non-European populations and in datasets with straight typed or sequenced HLA alleles.
