Relationship Between Thyroid Dysfunction and Ovarian Cancer

This review looks at the causes of the association between thyroid dysfunction (hyperthyroidism and hypothyroidism) and ovarian cancer (OC) risk. Epidemiological data have revealed that thyroid dysfunction, particularly hyperthyroidism, is associated with increased risk, progression, and mortality in patients with OC. In addition, research studies and databases have demonstrated that both the expression and localization of thyroid hormone receptors alpha (TRα) and beta (TRβ) and membrane thyroid hormone receptor integrin alpha V beta 3 (αvβ3) affect OC progression and survival in OC patients. Furthermore, this review described the levels of the thyroid hormones (THs) thyroxine (T₄) and 3,5,3'-triiodo-L-thyronine (T₃) in the blood of OC patients and their role in OC progression. Moreover, we present studies that reported the relationship between hyperthyroidism and hypothyroidism and the levels of metabolic hormones in the blood and the possible effects on metabolic reprogramming in OC cells. We also report data indicating the relationship between the treatment of thyroid dysfunction and OC progression. Finally, the cited case studies described the essential case of struma ovarii, which is OC, including thyroid tissue. This review describes the link between thyroid dysfunction and OC risk and progression, which may be important in treating OC patients with thyroid dysfunction.
