TGFB1 and neoplasm: To construct an lncRNA‐based model that could provide information on patient prognosis and therapeutic benefit, we first used correlation analysis to obtain 2654 lncRNAs that were significantly associated with the biological processes that trigger tumour metastasis and chemotherapy resistance, including angiogenesis, hypoxia, EMT and TGFβ signalling activation.16, 17, 18 Then, by consistently using the bootstrap and LASSO regression methods, we selected 52 robust stroma‐related prognostic lncRNAs to build a novel prognostic model, the SLS model.
