KIF18A and neoplasm: In colorectal cancer, Kif18A expression is associated with tumor stage, lymph node invasion, lymphatic invasion, venous invasion, and peritoneal dissemination.[14] In hepatocellular carcinoma, Kif18A expression is associated with high levels of α-fetoprotein, tumor size, TNM stage, and portal vein thrombus.[15] In breast cancer, Kif18A is associated with lymph node metastasis.[21] Therefore, Kif18A might play an oncogenic role in the occurrence and development of NSCLC.
