“…So far, several studies have reported on the association between XRCC1 polymorphisms and development of several types of cancers, including non-small cell lung cancer, gastric cancer, cervical cancer, hepatocellular carcinoma, pancreatic cancer, ovarian cancer, colorectal cancer, and thyroid cancer (Liu et al, 2012;Abdel-Fatah et al, 2013;Feng et al, 2014;Wang and Ai, 2014;Xia et al, 2014;Cătană et al, 2015;Han et al, 2015;Huang et al, 2015;Xu et al, 2015;Zhao and Chen, 2015;Ghosh et al, 2016). Liu et al (2015) observed a significant relationship between the XRCC1 Arg399Gln polymorphism and risk of cervical cancer in a meta-analysis comprising 2051 cervical cancer patients and 2919 control subjects.…”
