Rpl28 Promoter Polymorphism Rs4806668 Is Associated With Reduced Survival In Folfiri-Treated Metastatic Colorectal Cancer Patients
Cancer Research(2019)
摘要
Fluorouracil (5-FU), folinic acid, and irinotecan (FOLFIRI) is a standard treatment of metastatic colorectal cancer (mCRC). Our study aimed to investigate genetic variability in candidate genes in relation to patients9 outcomes using two independent cohorts of 417 FOLFIRI-treated mCRC cases recruited in Canada and Italy. We used a haplotype-tagging polymorphism (htSNP) approach to maximize the coverage of genetic variability of the selected genes and genotyping was performed using time-of-flight mass spectrometry iPLEX Sequenom Technology. Associations between polymorphisms and clinical outcomes were tested using Cox proportional hazards model adjusted for covariates. Of the genes tested, RPL28 encodes a ribosomal protein and its silencing was shown to enhance sensitivity to 5-FU and irinotecan in vitro. 1 RPL28 rs4806668Gu003eT was associated with a shorter progression-free survival (PFS) in the Canadian (hazard ratio (HR) 3.23, P = 0.013), Italian (HR 3.28, P = 0.021) and combined (HR 3.36, P This work is supported by the Canadian Institutes of Health Research. 1 Allen et al.
