We further examined predictive power of the 496 GI-related lncRNAs on prognosis of NSCLC patients and constructed the GIrLncSig comprising 11 GI-related lncRNAs (SCAT1, AC002401.4, AL079303.1, AL121761.1, TM4SF19-AS1, AC027288.1, AC019117.3, AC079949.2, AC026369.3, AL355472.2, and MMP2-AS1). This evidence concerns the gene TM4SF19 and non-small cell lung carcinoma.
