老年男性甲状腺结节性病变发展规律的探讨

The regularity of the occurrence and development of thyroid nodules in the 803 elderly male

目的探讨男性老年及老年前期甲状腺结节性病变的发生、发展变化规律。方法回顾性分析803例经超声诊断并随访10年以上的男性甲状腺结节性病变患者,根据结节长径的大小,由小至大分为五组进行统计分析。结果五组甲状腺结节第0年多数为多发性结节;少数单发结节者经10年随访有69例演变为多发性,26例仍为单发性。第2组甲状腺结节第5年及第10年增长绝对值与第1组比较无显著性差异(P>0.05);而第2组、第3组、第4组、第5组甲状腺结节第5年及第10年增加的百分比与第1组比较均有显著性差异(P<0.01)。结论男性老年人甲状腺结节随着年龄的增大而发病率增加,但增长缓慢,多数患者呈多发性,也有单发性演变为多发性。

Objective To study the regularity of the occurrence and development of thyroidnodules in elderly male. Methods The 803 elderly cases with ultrasound-diagnosed thyroid nodules followed up ten years were analyzed. According to the longest diameters, The basal sizes of the thyroid nodules were divided into five groups. Results The majority of thyroid nodules in the zero year were multiple, while 69 eases who had the single ones transmuted to multiple nodules after ten years follow-up, 26 eases kept single. In the fifth and tenth year, the increased sizes of group 2 had no difference compared to those of group 1 （ P 〉 0.05）. The increased pereentages in group 2.3.4,5 were signifieantly different from group 1 （ P 〈 0.01 ）. Conclusion The prevalence of thyroid nodule in the elderly male is slowly increasing with age, and the thyroid nodules are multiple or transmited to multiple nodules from single one in the majority.
