Aim:To define the impact of polymorphisms in genes involved in platinum-taxane and estrogen activity in the outcome of platinum-based treated ovarian cancer patients (OCP).Patients & Methods:Two hundred and thirty OCP were analyzed for 124 germ-line polymorphisms to generate a prognostic score for overall survival (OS), progression-free survival (PFS) and platinum-free interval (PFI).Results:ABCG2rs3219191D>I,UGT1Ars10929302G>A andUGT1Ars2741045T>C polymorphisms were significantly associated with all three parameters (OS, PFS and PFI) and were used to generate a score. Patients in high-risk group had a poorer OS (hazard ratio [HR]: 1.8; 95% CI: 1.3-2.7; p = 0.0019), PFS (HR: 2.0; 95% CI: 1.4-2.9; p < 0.0001) and PFI (HR: 1.9; 95% CI: 1.4-2.8; p = 0.0002) compared with those in low-risk group.Conclusion:The prognostic-score including polymorphisms involved in drug and estrogen pathways stratifies OCP according to OS, PFS and PFI.

Abstract

Aim:To define the impact of polymorphisms in genes involved in platinum-taxane and estrogen activity in the outcome of platinum-based treated ovarian cancer patients (OCP).Patients & Methods:Two hundred and thirty OCP were analyzed for 124 germ-line polymorphisms to generate a prognostic score for overall survival (OS), progression-free survival (PFS) and platinum-free interval (PFI).Results:ABCG2rs3219191D>I,UGT1Ars10929302G>A andUGT1Ars2741045T>C polymorphisms were significantly associated with all three parameters (OS, PFS and PFI) and were used to generate a score. Patients in high-risk group had a poorer OS (hazard ratio [HR]: 1.8; 95% CI: 1.3-2.7; p = 0.0019), PFS (HR: 2.0; 95% CI: 1.4-2.9; p < 0.0001) and PFI (HR: 1.9; 95% CI: 1.4-2.8; p = 0.0002) compared with those in low-risk group.Conclusion:The prognostic-score including polymorphisms involved in drug and estrogen pathways stratifies OCP according to OS, PFS and PFI.
