[Effect of hereditary factors on tolerance for surgical treatment in patients with lung cancer].
Genetic polymorphism at 10 independent loci (ABO, RH, HP, GC, PI, TF, ACP1, PGM1, GLO1, and PTC) was studied in male patients with lung squamous cell carcinoma. These patients were divided into two groups, depending on their tolerance for surgical intervention and on the postoperative course: (1) patients with an uneventful postoperative period and (2) patients with postoperative complications. The genetic structure of the combined sample at the loci studied did not differ from that of the control group consisting of health people (population control). Genotypic differences might manifest at the postoperative stage rather than at the onset of the disease, and determine the presence of postoperative complications. However, comparative analysis of the two groups of patients revealed their polar divergence in respect to phenotype and gene frequencies at certain loci. Moreover, the genotypic structure of patients in both groups differed from that in the combined sample and in the population control. In the group with postoperative complications, higher frequencies of the alleles GC*1F, ACP1*A, and HP*2 were observed. By contrast, the group of patients with an uneventful postoperative period demonstrated prevalence of the alternative alleles of these loci: GC*2, ACP1*B, and HP*1. The greatest difference in the distribution of informative allele frequencies was observed between the group of patients with postoperative complications and the control group. This is evidence that these groups significantly differ in their genetic structure. Such divergence is largely determined by the polymorphic multifunctional systems of serum proteins.
