The purpose of this paper is to assess the relationship between gene polymorphism in angiogenesis-related genes and radiation responses in nasopharyngeal carcinoma (NPC) patients. The genotypes of 180 NPC patients were analyzed by Sequenom MassARRAY. The response evaluation criteria in solid tumours were used for assessing efficacies, and the criteria of the Radiation Therapy Oncology Group or European Organization for Research & Treatment of Cancer were utilized for evaluating acute toxic reactions in response to radiation. Statistical methods included chi-square test, uni- and multivariate logistic regression analyses. Genotypic carriers of rs1800541 GT were at an elevated risk of developing grade 3+ oral mucositis, and a genetic variant of rs5333 was a predictor for a lower occurring risk of grade 2+ radiation-induced xerostomia. EDN1 rs1800541, rs2071942 and rs5370 variants were associated with a significantly higher risk of severe myelosuppression. SNPs in such angiogenesis-related genes as EDN1 rs1800541, rs2071942 & rs5370 and EDNRA rs5333 may serve as useful biomarkers for predicting the outcomes of NPC patients.
