Similar results were also seen in squamous cell lung carcinoma (P=0.003 for larger tumor size, P=0.017 for advanced TNM stage and P=0.003 for positive lymph node metastasis; Supplementary Table 1), whereas in lung adenocarcinomas, overexpression of Lasp1 showed no significant associations with clinicopathological features, as well as with different histological subtypes, including TRU (terminal respiratory unit) status, EGFR mutation and KRAS mutation (Supplementary Table 2). Here, KRAS is linked to squamous cell lung carcinoma.
