Low‐proliferation tumours in LUSC also exhibited poorer prognosis (Figure 4E,F) and pathways associated with tumour metastasis, including coagulation, EMT, angiogenesis and TGF‐β, were noticeably enriched in the low‐proliferation group of LUSC but were not detected in LUAD (Figure 4G). This evidence concerns the gene TGFB1 and neoplasm.
