Prognostic significance of the genetic variant of lymphotoxin alpha (p.Thr60Asn) in egyptian patients with advanced hepatocellular carcinoma

BackgroundHepatocellular carcinoma (HCC) is one of the most common malignancies worldwide in terms of mortality, and susceptibility is attributed to genetic, lifestyle, and environmental factors. Lymphotoxin alpha (LTA) has a crucial role in communicating the lymphocytes with stromal cells and provoking cytotoxic effects on the cancer cells. There are no reports on the contribution of the LTA (c.179 C>A; p.Thr60Asn; rs1041981) gene polymorphism to HCC susceptibility. The main aim of this study is to investigate the association of LTA (c.179 C>A; p.Thr60Asn; rs1041981) variant with the HCC risk in the Egyptian population.MethodsThis case-control study included 317 participants (111 HCC patients, and 206 healthy controls). The LTA (c.179 C>A; p.Thr60Asn; rs1041981) polymorphism was assessed by tetra-primer amplification refractory mutation system polymerase chain reaction (T-ARMS-PCR) technique.ResultsThe frequencies of the dominant and recessive models (CA + AA; AA) of the LTA (c.179 C>A; p.Thr60Asn; rs1041981) variant were statistically significant among HCC patients in comparison to controls (p = 0.01; p = 0.007; respectively). The A-allele of LTA (c.179 C>A; p.Thr60Asn; rs1041981) variant was statistically significant in HCC patients in comparison to controls (p < 0.001).ConclusionThe LTA (c.179 C>A; p.Thr60Asn; rs1041981) polymorphism was independently associated with an increased risk for hepatocellular carcinoma in the Egyptian population.

Automated summary

This study investigated the association between LTA (c.179 C>A; p.Thr60Asn; rs1041981) polymorphism and hepatocellular carcinoma (HCC) in the Egyptian population. The results showed that LTA (c.179 C>A; p.Thr60Asn; rs1041981) polymorphism is independently associated with an increased risk for HCC.
