Relationship Between The Upregulation Of Notch1 Signaling And The Clinical Characteristics Of Patients With Papillary Thyroid Carcinoma In East Asia

PurposeMany studies have aimed to clarify the relationship between Notch1 signaling and papillary thyroid carcinoma(PTC),but the results have been inconsistent to date.In the present study,a systematic review and meta-analysis were performed to analyze the relationship between Notch1 signaling and the clinical characteristics of PTC.MethodsLiterature databases,including PubMed(Medline),Embase and China National Knowledge Infrastructure(CNKI),were searched for relevant studies from inception to April 2018.A total of five studies,including 421 patients with PTC from China and South Korea,were included in the meta-analysis.ResultsThe results revealed that the upregulation of Notch1 signaling was positively correlated with lymph node metastasis in patients with PTC(OR=3.25,95%CI:1.14-9.23,P=0.03).Additionally,positive correlations were found between Notch1 signaling and tumor size(OR=4.34,95%CI:1.66-11.38,P=0.003),capsular invasion(ORF=3.49,95%CI:1.90-6.41,P<0.0001)and clinical stage of PTC(OR=2.31,95%CI:1.05-5.11,P=0.04).ConclusionsThe Notch1 signaling pathway may play a catalytic role in the progression of PTC,and upregulation of Notch1 signaling may have significant predictive value for the clinical prognosis of PTC.
