It is known that a great extent of radiation is emitted from the medical instruments used in hospitals and that radiation exposure can cause thyroid cancer. However, the correlation between occupational radiation exposure in hospitals and thyroid disease is not extensively recognized.
The subjects of the study were female nurses, who worked at a single hospital and female, who had undergone a health examination at the same hospital during the same period. The 1,024 nurses and 2,631 healthy women were enrolled for the present study. All the participants were screened using thyroid ultrasonography, and fine-needle aspiration & cytology was performed on potentially malignant nodules.
Thyroid nodules were present in 315 nurses (30.8%) and 1,023 health check-up female (38.9%). Typically, 107 nurses (10.4%) and 201 health check-up female (7.6%) had suspicious nodule and were further tested with ultrasonography guided fine-needle aspiration & cytology. The 16 nurses (1.6%) and 38 health check-up female (1.4%) were diagnosed with thyroid cancer. The prevalence of thyroid nodules was enhanced in both the groups and a significant increase was noted in health check-up female group (P<0.05); however, no difference was seen in the incidence of thyroid cancer in both the groups (P>0.05).
In our study, working in a hospital does not increase the prevalence of thyroid nodules or thyroid cancer.
众所周知，医院使用的医疗器械会发出大量辐射，且辐射暴露可导致甲状腺癌。然而，医院职业辐射暴露与甲状腺疾病之间的相关性尚未得到广泛认可。
本研究的对象为在同一家医院工作的女护士以及同期在该医院接受健康检查的女性。本研究共纳入1024名护士和2631名健康女性。所有参与者均接受甲状腺超声检查，对潜在恶性结节进行细针穿刺及细胞学检查。
315名护士（30.8%）和1023名健康检查女性（38.9%）存在甲状腺结节。其中，107名护士（10.4%）和201名健康检查女性（7.6%）有可疑结节，并进一步接受超声引导下细针穿刺及细胞学检查。16名护士（1.6%）和38名健康检查女性（1.4%）被诊断为甲状腺癌。两组甲状腺结节的患病率均有所增加，健康检查女性组有显著增加（P<0.05）；然而，两组甲状腺癌的发病率未见差异（P>0.05）。
在我们的研究中，在医院工作不会增加甲状腺结节或甲状腺癌的患病率。
