In summary, we found that the p53 p. Pro72Arg, MDM2 c.14 + 309T > G and MDM2 c.-461C > G polymorphisms are associated with toxicity risks following platinum-based chemotherapy treatment in advanced NSCLC patients.
This study investigated whether the functional polymorphisms in P53 pathway genes, P53 Arg72Pro (rs1042522), P73 G4C14-to-A4T14 (rs2273953 and rs1801173), and MDM2 T309G (rs2279744), alone or in combination, affect survival in advanced non-small cell lung cancer (NSCLC) patients.
The purpose of the study was to investigate whether polymorphisms of p53 codon 72 (Arg72Pro) and MDM2 SNP309 (309T>G) affect p53 expression and the clinical outcome of patients with advanced nonsmall cell lung cancer (NSCLC).
