甲状腺结节的发生、发展与基因因素、自身免疫、电离辐射、年龄、碘摄入量等多种因素相关。既往研究发现通过触诊可发现的结节占2%~7%,如今高分辨率超声在甲状腺领域的应用,其检出率有很大提高,也有通过颈部血管超声、CT、MRI等影像学检查的广泛开展而意外发现的。甲状腺癌是最常见的内分泌恶性肿瘤,据美国甲状腺协会2006年的报道,其发病率达5%~10%,近年来呈逐年攀升趋势。澳大利亚甲状腺癌的发病率从1973年至2002年在男性人群增长了177.8%,女性人群增长了252.2%[1]。而我国尚缺乏全国范围的流行病学资料,但根据现有资料显示我国甲状腺结节发病率也在逐年上升。对于甲状腺结节的首要目的是明确其性质,通常借助于实验室检查、超声、甲状腺显像及细胞学检查(FNAB)。
The occurrence and development of thyroid nodules are related to many factors such as genetic factors, autoimmunity, ionizing radiation, age, iodine intake and so on. Previous studies have found that palpation can be found by palpation 2% to 7%, now high-resolution ultrasound in the thyroid field, the detection rate has greatly improved, but also through the neck of the blood vessels, CT, MRI and other images Unexpected discovery of a wide range of school examinations. Thyroid cancer is the most common endocrine malignant tumor. According to the report of the American Thyroid Association in 2006, the incidence of thyroid cancer is 5% -10%, which shows a gradual increase in recent years. The incidence of thyroid cancer in Australia increased by 177.8% in the male population and 252.2% in the female population from 1973 to 2002 [1]. However, there is still a lack of epidemiological data in our country, but according to the available data, the incidence of thyroid nodules in our country is also increasing year by year. The primary purpose for thyroid nodules is to clarify their properties, usually with the aid of laboratory tests, ultrasound, thyroid imaging and cytology (FNAB).
