Polymorphisms of HLA-DQB1 predict survival of hepatitis B virus-related hepatocellular carcinoma patients receiving hepatic resection.

Objective: Human leukocyte antigen (HLA)-DQB1 genetic polymorphisms are associated with an increased risk of hepatitis B virus-related hepatocellular carcinoma (HBV-related HCC). We aimed to evaluate the influence of genetic polymorphisms in HLA-DQB1 exon region and neighboring single nucleotide polymorphisms (SNPs rs9275572 and rs2244546) on survival of HBV-related HCC patients undergoing hepatic resection.

Methodology: All SNPs were genotyped by sequencing DNA isolated from tumor samples of 483 patients with HBV-related HCC.

XRCC1 rs25487 genetic variant and TP53 mutation at codon 249 predict clinical outcomes of hepatitis B virus-related hepatocellular carcinoma after hepatectomy: A cohort study for 10 years' follow up.

Aim: To investigate the effects of rs25487 (the DNA repair gene: x-ray repair complementing defective repair in Chinese hamster cells 1 [XRCC1]) and codon 249 mutation (TP53 gene) on clinical outcomes of post-hepatectomy hepatitis B virus (HBV)-related HCC.

Methods: The XRCC1 rs25487 polymorphism and TP53 mutation at codon 249 of 485 hepatitis B surface antigen positive patients subjected to hepatectomy were genotyped via direct sequencing. SPSS software version 16.
