Abstract:
Objective The onset and progression of lung cancer correlate closely to individual genetic background .This study evaluated the correlation between the onset risk of lung cancer and short tandem repeat (STR) polymorphisms in order to find a new pathway for investigating the pathogenesis of lung cancer . Methods Using PCR and electrophoresis on 15 STR loci , we studied the gene and genotype frequencies of peripheral vein blood specimens from 120 lung cancer patients and 156 healthy individuals in Nan-jing area.According to the differences in the allele distribution of the 15 STR loci, we evaluated the susceptive and/or resistant factors relevant to lung cancer . Results There were statistically significant differences between the lung cancer patients and healthy controls at alleles 10, 15.2, and 16 of the loci CSF1PO, D19S433, and D3S1358 (P<0.05, OR>1), as well as at alleles 14 and 14.2 of the loci CSF1PO and D19S433 (P<0.05, OR<1). Conclusion It is possible that alleles 10, 15.2 and 16 of the loci CSF1PO, D19S433, and D3S1358 are susceptive factors and alleles 14 and 14.2 of the loci CSF1PO and D19S433 are resistant factors relevant to lung cancer .
