Thyroid cancers from the Cancer Registry of Singapore over a ten . year period were analysed in two separate periods 1968-'72 and 1973-'77. Biopsy materials were reviewed and classified according to the WHO Classification of thyroid cancers. The crude incidence rates per 100.000 population per year was 1 in males and 3 in females. No definite ethnic group differences were observed. Papillary carcinoma was by far the commonest cancer followed by follicular carcinoma. Comparison between the two periods of study revealed a slight tendency to decline in incidence among the females. The papillary-follicular carcinoma ratio showed a progressive increase with time. The incidence of undifferentiated carcinoma had also declined over the same period. This may reflect changes in the environment which have an influence on the incidence and histological types of thyroid cancers in Singapore.
对新加坡癌症登记处十年期间的甲状腺癌进行了分析，分为两个不同时间段：1968 - 1972年和1973 - 1977年。根据世界卫生组织甲状腺癌分类对活检材料进行了审查和分类。每年每10万人口的粗发病率男性为1例，女性为3例。未观察到明确的种族差异。乳头状癌是迄今为止最常见的癌症，其次是滤泡状癌。两个研究时间段的比较显示女性发病率有轻微下降趋势。乳头状 - 滤泡状癌比例随时间呈逐渐上升趋势。同期未分化癌的发病率也有所下降。这可能反映了环境变化对新加坡甲状腺癌的发病率和组织学类型产生了影响。
