Abstract:
Objective: To analyze the associations of Notch 1 expression with the lymph node metastasis and distant metastasis of papillary thyroid carcinoma (PTC) by Meta analysis. Methods: Computer retrieve was conducted in PubMed (MEDLINE), Cochrane Library, EMBASE, China Journal Full-text Database (CNKI), China Biology Medicine disc (CBMdisc) to search the studies which were about the association of Notch1 signal with the lymph node and distant metastases of PTC, and published from 2010 to 2017. The literatures were screened and evaluated, then the information was extracted independently by 2 researchers according to the literature selection criteria. Meta analysis was performed using RevMan 5.3 and STATA 12.0 software. The odds ratio (OR) and 95% confidence interval (CI) were calculated. The sensitivity analysis and publication bias test were performed. Results: A total of 7 clinical case-control studies involving 743 patients with PTC were selected. Meta-analysis showed that the expression of Notch1 was significantly positively correlated with lymph node metastasis of PTC (OR = 4.68, 95% CI: 3.00-7.30), furthermore the test for overall effect showed that Z = 6.80 and P < 0.000 01. However, there was no significant correlation between Notch1 expression and the distant metastasis of PTC (OR = 1.59, 95% CI: 0.88-2.89), the test for overall effect showed that Z and P values were 1.53 and 0.1 3 respectively. Conclusion: The Notch1 signaling pathway plays a promoting role in the lymph node metastasis of PTC, which suggests that the expression of Notch1 has a certain predictive value for the clinical prognosis of PTC.
