Abstract:
179 Background: Recently, genetic polymorphism in HSD3B1 has been shown to be associated with oncological outcome when treated with androgen-deprivation therapy (ADT) for prostate cancer. However, its impact on prognosis among different ethnicities remains unclear. Then, we aimed to investigate the significance of missense polymorphism in HSD3B1 gene encoding 3β-hydroxysteroid dehydrogenase among men treated with primary ADT for metastatic prostate cancer. Methods: This study included 104 Japanese patients with metastatic prostate cancer treated with primary ADT. The association of HSD3B1 (rs1047303, 1245C) with clinicopathological parameters and prognosis, including progression-free survival and overall survival, was examined. Results: Clinicopathological parameters were comparable between men with homozygous wild-type and men with heterozygous and homozygous variant types in HSD3B1 gene. Men carrying heterozygous and homozygous variant types in HSD3B1 gene showed higher progression risk [hazard ratio (95% confidence interval), 2.34 (1.08–4.49), P = 0.033], but not any-caused death risk [hazard ratio (95% confidence interval), 1.36 (0.52–2.92), P = 0.50] , compared with men carrying homozygous wild-type. Conclusions: This study confirmed the finding that HSD3B1 genetic variation is associated with high risk of progression in Japanese men treated with primary ADT for metastatic prostate cancer, suggesting universal significance among different ethnicities.
