甲状腺癌相关因素研究

研究证明肥胖为 DTC 发病危险因素；碘能增加甲状腺乳头状癌的发病风险，却能降低滤泡癌的发病风险；维生素 D 能降低 DTC 的发病风险，但仍没有足够证据证明维生素 A、C、E 能降低 DTC的发病风险；酒精可能降低 DTC 发病风险，但内在机制仍不清楚；摄入外源毒素增加 DTC 发病风险。明确保护因素与危险因素对于 DTC 的预防工作有十分重要的意义。

Research in thyroid carcinoma related factors

Recent studies have revealed that obease increases the risk of differentated thyroid carcino-ma (DTC);iodine increases the risk of papillary thyroid carcinoma wheras decreases the risk of follicular thy-roid carcinoma;vitamin D decreases the risk of DTC,but there are not enough evidences to prove that vitamin A,C and E can decrease the risk of DTC;alcohol may decrease the risk of DTC,but the mechanism is still un-known;xenobiotics increases the risk of DTC.It is essential for DTC prevention to clarify the protection and risk factors.
