The level of lncRNA KTN1-AS1 is correlated with TNM stage (p = 0.0029), histological grade (p = 0.012) and lymph node metastasis (p = 0.020), and the high expression of KTN1-AS1 can reduce the OS of NSCLC patients (Liu et al., 2020). This evidence concerns the gene KTN1 and non-small cell lung carcinoma.
