BACKGROUND: Estramustine phosphate sodium (EMP) frequently causes side-effects such as gastrointestinal discomfort, nausea, and edema in extremities. We analyzed single nucleotide polymorphisms (SNP) in the 17beta-hydroxysteroid dehydrogenase (HSD17B) genes, which are involved in the metabolism of EMP, to predict the risk of EMP side-effects in prostate cancer patients.METHODS: We performed genotyping of SNP in the HSD17B genes of 44 Japanese patients with newly diagnosed prostate cancer. The association of SNP and individual EMP side-effects was evaluated.RESULTS: Peripheral edema occurred more frequently in patients with C/C genotype of IMS-JST123219 than in those with C/G genotype (OR: 5.47, 95% CI: 1.27-23.64). Haplotype analysis showed that appetite loss was associated with the G allele of IMS-JST123219 and the T allele of IMS-JST123218 (OR: 9.13, 95% CI: 1.15-72.76).CONCLUSIONS: These preliminary data demonstrated that analyses of SNP in the HSD17B genes might predict the occurrence of side-effects from EMP.
