Prospective Evaluation of XRCC-1 as a Biopredictor for Survival Outcomes in Patients of Head and Neck Squamous Cell Carcinoma (HNSCC): A Meta-analysis
Abstract Background: Epidemiologic studies have demonstrated that X-ray repair cross-complementary group 1 (XRCC1) is one of the susceptibility factors in head and neck squamous cell carcinoma(HNSCC) patients. However, its clinical prognostic impact remains controversial. Thus, a meta-analysis was performed to clarify the survival value of XRCC1 in HNSCC patients.Methods: Following the Preferred Reporting Items or Systematic Reviews Meta Analyses (PRISMA) 2020 guidelines, literature searches were systematically performed by PubMed, EMBASE and Web of Science with a manual retreive to evaluate the prognostic consequence of XRCC1 in HNSCC patients. Hazard ratios (HRs) and 95% confidence intervals (CIs) were collected to estimate the correlation between XRCC1 and the survival outcomes of HNSCC patients.Results: Ten studies including 2086 HNSCC patients who satisfied the inclusion and exclusion criteria were included in this meta-analysis. The meta-analysis showed that high XRCC1 expression and Arg399Gln and Arg194Trp were significantly correlated with poorer overall survival (OS), with HRs of 1.97 (95% CI, 1.36–2.84, P<0.001), 1.30 (95% CI, 1.12–1.51, P<0.001), and 1.65 (95% CI, 1.18–2.32 P<0.05), respectively.Conclusion: XRCC1 was associated with poorer survival outcomes in HNSCC patients. Hence, XRCC1 is a potential therapeutic target for HNSCC.
