With the help of the Gene Expression Profiling Interactive Analysis (GEPIA) database (http://gepia.cancer-pku.cn/detail.php?gene=RGS1), it was noticed that increased tumour RGS1 only exhibited a weak correlating trend (without statistical significance) with shortened DFS (P = 0.190, supporting information Figure S1A) and OS (P = 0.380, supporting information Figure S1B) in NSCLC patients; regrettably, blood RGS1 lacked relevant data. Here, RGS1 is linked to neoplasm.
