Résumé
Hypothyroidism is a common adverse reaction in clinical multi-target tyrosine kinase inhibitor (TKI) and may be used as a predictor of efficacy of TKI drugs.Studies show that hypothyroidism is significantly associated with good prognosis in patients with renal cell carcinoma treated with multi-target TKI,which may be related to inhibition of vascular endothelial growth factor receptor pathway,potential off-target effects and inhibition of cell proliferation.Whereas in the patients with hepatocellular carcinoma who received multi-target TKI therapy,hypothyroidism is an indicator of poor prognosis,which is related to the T3/TR pathway regulating liver cancer growth and invasion.The predictive function and mechanism of thyroid hormone levels in different tumor patients receiving multi-target TKI drugs are different,and further research is still needed.
