title: Interleukin 1 receptor antagonist (IL-1RA) polymorphism in women with cervical cancer.
abstract: BACKGROUND
  Several studies suggest that immunological components play a key role in the development of cervical cancer. Polymorphism in the IL-1 RA gene was associated with various malignant diseases. Data is lacking for cervical cancer.
  
  
  METHODS
  In a prospective study we analysed the polymorphism of IL-1RA in 113 women with cervical cancer and 107 with benign diseases. Genomic DNA fragments were amplified by PCR.
  
  
  RESULTS
  The distribution of genotype frequencies was different between the study and control group with respect to allele 2 heterozygotes (24.8% vs. 13.1%; p = 0.04) but not in the frequencies of allele 1/3 and homozygous allele 2. There were no differences between IL-1 RA 1/2 polymorphism and all other alleles in tumour stage, grading, recurrence status and age.
  
  
  CONCLUSIONS
  This data supports the role for allele 2 of the gene encoding for IL1-RA as a genetic determinant of cervical cancer.
