The occurrence of hypothyroidism in the treatment of mRCC with TKIs is a major side effect. A comprehensive search was performed in Pubmed, Cochrane Library, Institute for Scientific Information, and CKNI. The following keywords and descriptors were used during the search and were combined in a number of sequences in English and Chinese languages: protein kinase inhibitors (including sunitinib, pazopanib, tivozanib, cabozantinib, axitinib, sorafenib), hypothyroidism and renal cell carcinoma.Results: Scholars have studied the clinical relationship between hypothyroidism and TKI treatment and its molecular biology mechanism. Most studies hold that hypothyroidism occurring during TKI therapy may serve as potential biomarkers of response and efficacy of treatment, but there is no consensus on this point.Conclusion: The mechanism of hypothyroidism occurring is still unclear. Therefore, more studies are needed to clarify whether better outcomes are associated with TKI-induced hypothyroidism in mRCC patients, helping to maximize the treatment outcome of mRCC patients.Keywords: metastatic renal cell carcinoma, mRCC, tyrosine kinase inhibitors, TKIs, hypothyroidism, progression-free survival, PFS, overall survival, OS
