Abstract:
Objective To investigate and evaluate the detection and the variety of histology type constituent of the thyroid malignant tumor before and after universal salt iodization.Methods 1011 clinical pathological data of thyroid malignant tumor confirmed pathologically from 1961 to 2000 was retrospectively analyzed.The detection rate of thyroid malignant tumor,the constituent ratios of each histology type and the changes of age and sex distribution in main types of thyroid malignant tumor were determined.Results The total detection rate of thyroid malignant tumor after universal salt iodization (USI) (0.69%) were obviously increased compared with before universal salt iodization(0.46%,P40 years old) than before USI(≤40 years old).The incidence rates of thyroid malignant tumor in female patients were higher than male patients before and after USI.Conclusion The proportion and average age of thyroid malignant tumor increases after USI.The histological types of thyroid carcinoma have changes after USI:the proportion of PC increases obviously,the proportion of FC decreases accordingly.The average age of thyroid malignant tumor sufferers tends to increase and the peak ages of PC,FC and UC raise after USI.
