LDOC1 and squamous cell lung carcinoma: Kaplan–Meier analysis demonstrated that patients with stage IV lung cancers, including lung squamous cell carcinoma (LSQC, n = 19) and lung adenocarcinoma (n = 47), expressing low LDOC1 levels had a significantly shorter (p = 0.004, log-rank test) overall survival than patients expressing high LDOC1 levels (Figure 2D).
