Abstract:	Objective To investigate whether certain polymorphisms are correlated with leiomyoma susceptibility, i.e., interleukin (IL)-1, IL-2, IL-4, IL-8, IL-12, and IL-18, which are all immunomodulatory cytokines that play important roles in host immune responses against cancers. Setting Departments of gynecology and genetics in a medical center. Patient(s) Women were divided into: [1] a leiomyoma group (n = 162) and [2] a nonleiomyoma group (n = 156). Intervention(s) Genotyping for the IL-1β-511 promoter, IL-1β exon 5, IL-1Ra, IL-2 114, IL-4 −590 intron 3, IL-8 3′-UTR 2767, IL-12Rβ1 codon 378, and IL-18 105 were evaluated by polymerase chain reaction-restriction fragment length polymorphism. Main Outcome Measurement(s) Genotypes and allelic frequencies in both groups were compared. Result(s) Proportions of IL-12Rβ1 codon 378 CC/CG/GG in the leiomyoma and nonleiomyoma groups were: [1] 7.4%/43.8%/48.8% and [2] 11.5%/54.5%/34%, respectively. Distributions of other polymorphisms in both groups were not significantly different. Proportions of IL-1β-511 promoter CC/CT/TT were: [1] 22.8%/50%/27.2% and [2] 21.8%/57.1%/21.1% in the leiomyoma and nonleiomyoma groups, respectively. The IL-1β exon 5 E1 homozygote/heterozygote/E2 homozygote were: [1] 96.3%/3.7%/0% and [2] 96.9%/3.1%/0% in the leiomyoma and nonleiomyoma groups, respectively. Alleles I/II/III/IV/V for IL-1Ra were: [1] 92.6%/7.1%/0.3%/0/0% and [2] 93.9%/5.7%/0%/0.4/0% in the leiomyoma and nonleiomyoma groups, respectively. The IL-2 114 G homozygote/heterozygote/T homozygote were: [1] 27.8%/49.4%/22.8% and [2] 20.5%/53.2%/26.3% in the leiomyoma and nonleiomyoma groups, respectively. The IL-4 −590 intron 3 RP1 homozygote/heterozygote/RP2 homozygote were: [1] 64.8%/32.7%/2.5% and [2] 69.2%/26.9%/3.9% in the leiomyoma and nonleiomyoma groups, respectively. The IL-8 3′-UTR 2767 A homozygote/heterozygote/G homozygote were: [1] 14.2%/43.8%/42% and [2] 20.5%/41.7%/37.8% in the leiomyoma and nonleiomyoma groups, respectively. The IL-18 AA/AC/CC were: [1] 56.8%/40.7%/2.5% and [2] 59%/39.7%/1.3% in the leiomyoma and nonleiomyoma groups, respectively. Conclusion(s) The IL-12Rβ1 codon 378 G homozygote and G allele are related to a higher susceptibility to leiomyoma. The IL-1β-511 promoter, IL-1β exon 5, and IL-1Ra, IL-2 114, IL-4 −590 intron 3, IL-8 3′-UTR 2767, and IL-18 105 gene polymorphisms are not correlated with the development of leiomyoma.
