To further explore the critical efficiency of XPC in the survival of NSCLC patients, we analyzed the relationship between the XPC mRNA expression level and the survival of NSCLC patients from 2437 lung tumors using publicly available datasets (2015 version) (http://kmplot.com/analysis/index.php?p=service&cancer=lung). The gene discussed is XPC; the disease is non-small cell lung carcinoma.
