Abstract:
Objective To investigate the clinical value of vitamin D receptor ( VDR) gene polymorphism in lung cancer screening .Methods From January 2017 to September 2017 ,2000 lung cancer screening patients in the Fifth People's Hospital of Foshan were selected in the research .The VDR gene polymorphism was determined by phenol-chloroform method .DNA was extracted from the peripheral blood of patients ,different VDR genotypes [ Bsm1 bb and Bb),Apal(aa,Aa and AA)] were analyzed by univariate analysis to determine the correlation between lung cancer and VDR gene polymorphism and lung cancer incidence by multivariate non -conditional logistic regression analysis, thus to explore the relationship between different VDR genotypes and risk factors of lung cancer . Results The level of serum vitamin D in the non -lung cancer patients was (46.5 ±2.3) ng/L,which was signifi-cantly higher than (26.5 ±1.1)ng/L in the lung cancer patients (t=49.614,P=0.000).The Bsm1bp genotype, Apal aa genotype and Apal Aa genotype were the risk factors of lung cancer .The Bsm1bp and Apal Aa genotypes were independent risk factors of lung cancer .Conclusion The Bsm1 locus and Apal locus Aa genotype in VDR receptor are high risk population of lung cancer .Therefore,we should pay more attention to the clinical screening and avoid misdiagnosis and missed diagnosis .
