The incidence of thyroid cancer is increasing worldwide. This is not accompanied by a corresponding increase in mortality. In contrast, in most populations' thyroid cancer mortality has been decreasing in recent decades, although there are some notable exceptions. Relatively few studies focus on mortality and in Latin America we do not find evidence on the temporal trend of mortality. The study of the epidemiology of the thyroid cancer should be approached with a suitable methodology and with data based on the population. Trends should be expressed as an annual percentage of change and/or average annual rate of change. An appropriate method for analyzing trends in thyroid cancer mortality rates is the Joinpoint regression analysis. Previously published findings are described, and the methodology used is compared.
At the global level, Ecuador is one of the countries with the highest incidence rate of thyroid cancer. However, mortality data are scarce and not rigorous. It is important to raise awareness of updated and reliable population-based data on the trend of thyroid cancer mortality in Eccuador.
全球范围内甲状腺癌的发病率正在上升。但与之不相称的是，死亡率并没有相应增加。相反，在最近几十年，大多数人群的甲状腺癌死亡率一直在下降，尽管也有一些显著的例外。相对较少的研究关注死亡率，在拉丁美洲，我们没有发现关于死亡率时间趋势的证据。研究甲状腺癌的流行病学应该采用适当的方法，并使用基于人群的数据。趋势应该表示为年变化百分比和/或平均年变化率。分析甲状腺癌死亡率趋势的一种适当方法是 Joinpoint 回归分析。描述了之前发表的研究结果，并比较了所使用的方法。
在全球范围内，厄瓜多尔是甲状腺癌发病率最高的国家之一。然而，死亡率数据稀缺且不严谨。厄瓜多尔有必要提高对基于人群的甲状腺癌死亡率趋势的最新和可靠数据的认识。
