Abstract

AIM: The study aimed to unveil the effect of TK1 expression on the clinicopathological significance and prognosis in patients with lung cancer. Results & methodology: Studies for meta-analysis were selected according to a thorough literature search in databases (PubMed, EMBASE and Chinese databases). Ten studies containing 1393 lung cancer patients were investigated in our analysis. The TK1 overexpression was associated with poorer overall survival(OS) in lung cancer patients (hazard ratio = 1.881; 95% CI:1.318-2.684, Z = 3.48; p = 0.001). Furthermore, The TK1 expression is associated with the clinicopathological features of lung cancer patients (tumor type, age, lymph node metastasis, distant metastasis and tumor, node, metastasis [TNM] stages). Discussion & conclusion: The TK1 expression might have a supportive implication in assessing biological behavior and prognosis of lung cancer patients.
