Single Nucleotide Polymorphisms in DNA Repair Genes (XRCC1, XRCC2, XRCC3) and Their Association with Radiotherapy Toxicity among Head and Neck Cancer Patients:A Study from South-Western Maharashtra.

ABSTRACT:

Background

The genetic polymorphisms in DNA repair genes and their correlation with normal tissue toxicity in response to radiation therapy has not been consistently proven in many of the studies done in head and neck cancers (HNC). This study was intended to investigate the association of most common single nucleotide polymorphisms of DNA repair genes with acute radiation induced toxicities such as skin reactions and oral mucositis in normal tissue from HNC patients receiving radiotherapy from South-Western Maharashtra.

Methods

Two hundred HNC patients receiving radiotherapy were enrolled in this study and the radiation injuries in the form of skin reactions and oral mucositis were recorded. Three single nucleotide polymorphisms (SNPs) rs1799782, rs25489) rs25487 of XRCC1 g
