ABSTRACT
Background:
The purpose of this study was to investigate the genotype frequencies of CYP3A4*1B and CYP3A5*3 in lung cancer patients which may be useful in determining the patients’ predisposition to platinum based therapies, and may be helpful for individualized drug dosing and improved therapeutics and disease management.Results:
We evaluated these two common polymorphisms in south Indian population, based on case-control study of 126 lung cancer cases and 111 controls using a PCR-RFLP-based assay. The investigation of the CYP3A4*1B gene polymorphism revealed, no significant difference in distribution between the lung cancer patients and the controls (p=0.65) . The distribution of CYP3A5*3 homozygous genotypes and heterozygous plus homozygous genotypes were significantly associated (p=0.0004 & p=0.0001) with lung cancer patients, and the *3/*3 genotype had a 4.38 fold increased risk for lung cancer. In our study *1A/*1B heterozygous genotype patients were found to constitute a major percentage of patients receiving Gemcitabine plus carboplatin therapy.Conclusions:
In conclusion, the results of our study indicated a relationship between CYP 3A4*1B and CYP3A5*3 polymorphisms and genetic predispositions to lung cancer. Thus detection of CYP3A4*1B/CYP3A4 and CYP3A5*3/CYP3A5 genotype frequencies in Indian population may be important in view of interindividualized drug dosing, improved therapeutics and disease management.
