KRT17 and lung adenocarcinoma: Subgroup analysis showed that the high expression of KRT17 was only associated with sex (p = 0.002) in lung squamous cell carcinoma, while the high expression of KRT17 was associated with degree of differentiation (p = 0.036), advanced TNM stage (p = 0.005), and lymph node metastasis (p = 0.011) in lung adenocarcinoma (Wang et al., 2019).
