"Study suggests that rs1233255 SNP in PMS1 is associated with acute adverse events (AEs) and three SNPs including rs4920657 rs5743030 and rs5743100 in PMS1 are associated with survival of rectal cancer patients receiving postoperative chemoradiotherapy (CRT). Therefore these polymorphisms may be potential independent biomarkers for predicting AEs and prognosis in rectal cancer patients receiving postoperative CRT."xsd:string
