Purpose of review 

In this review, we evaluate recent findings related to the association between obesity and thyroid cancer.

Recent findings 

During the last several decades, the prevalence of obesity and thyroid cancer have been increasing in parallel on a global scale. Current evidence suggests that the growing incidence of differentiated thyroid cancer (DTC) is pathogenically linked to the spread of obesity, but the biological mechanisms that may explain this connection have been only partially described. Furthermore, unlike other tumors, data on the impacts of obesity on the aggressiveness of DTC and response to treatment of DTC remain conflicting.

Summary 

Emergent knowledge regarding the links between obesity and thyroid cancer suggests a relevant role for obesity as a risk factor for DTC, with no apparent impact on its aggressiveness.

肥胖是甲状腺癌的危险因素

审查目的 

在这篇综述中，我们评估了肥胖与甲状腺癌之间相关性的最新发现。

最近的发现 

在过去的几十年中，肥胖和甲状腺癌的发病率在全球范围内呈平行上升趋势。目前的证据表明，分化型甲状腺癌（DTC）发病率的增长与肥胖的传播具有致病性，但可能仅部分描述了可能解释这种联系的生物学机制。此外，与其他肿瘤不同，肥胖对DTC侵袭性的影响以及对DTC治疗反应的数据仍然相互矛盾。

概要 

关于肥胖症和甲状腺癌之间联系的新兴知识表明，肥胖症是DTC的危险因素，但对它的侵袭性没有明显影响。
