Résumé
Objective To investigate the relationship between genetic single-nucleotide polymorphisms of ligase Ⅳ (LIG4) and heat shock protein B1 (HSPB1) and prognosis in nasopharyngeal carcinomas.Methods DNAs were extracted by phenol-chlorofrom method from peripheral blood samples of 168 nasopharyngeal carcinoma patients.Genetic single-nucleotide polymorphisms were divided by Taqman realtime polymerase chain reaction (PCR).All statistical analyses were performed with statistical product and service solutions v13.0.A p-value of less than 0.05 was confirmed as statistical significance.Single-factor and multiple-factor logistic analyses were used to calculate odds ratio (OR) and 95％ confidence interval (CI).Long-rank test and COX were also used.Results No relationship was found between the recurrence,metastasis and overall survival of nasopharyngeal carcinoma and genetic single-nucleotide polymorphisms of LIG4 and HSPB1 with single-factor and multiple-factor logistic analyses.Conclusions LIG4 rs1805388 and HSPB1 rs2868371 had no relationship with prognosis of nasopharyngeal carcinomas.
