title: [Relationship between polymorphism of hypoxia inducible factor-1alpha and cervical cancer in Han population in Sichuan Province of China].
abstract: OBJECTIVE
  To investigate the relationship between single nucleotide polymorphism (SNP) of hypoxia inducible factor-1alpha (HIF-1alpha) C1772T and genetic susceptibility to and clinical-pathological features of cervical cancers in Han population in Sichuan province of China.
  
  
  METHODS
  A case control study was undertaken in Sichuan province of China, with 97 patients with uterine cervical cancer as case group and 117 negative for intraepithelial lesion or malignancy (NILM) patients as control group. Their gene types in HIF-1alpha C1772T were identified with a combination of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).
  
  
  RESULTS
  The distribution of the frequencies of T/T, T/C and C/C genotypes in the two groups differed significantly (P < 0.01); T allele frequency in the patients with cervical cancer was much higher than that in the controls (P < 0.01). There were no significant differences in the distributions of T/T, T/C and C/C genotypes among cervical cancer patients at different FIGO stages, pathological grading, stromal invasive depth, lymph node metastasis and vascular invasions (P > 0.05).
  
  
  CONCLUSIONS
  T/C and T/T genotypes of HIF-1alpha C1772T are genetic susceptibility factors for cervical cancer in Han population in Sichuan province of China. HIF-1alpha C1772T SNP probably has no relationship with clinical-pathological features of cervical cancer.
