EHD1 and lung cancer: Likewise, in TCGA lung cancer samples, patients in early stages (stages I and II) with low EHD1 expression had a longer OS and DFS than those with high EHD1 expression (P = 0.004 and 0.007, respectively), indicating that EHD1 level may indicate NSCLC patient prognosis during early clinical stages, although there was no significant difference in the OS and DFS of advanced patients (Fig. 5e, f).
