A worldwide journey of thyroid cancer incidence centred on tumour histology
Menée à partir des données de 25 pays sur la période 1998-2012, cette étude analyse l'évolution de l'incidence du cancer de la thyroïde par sous-type histologique
Over the past three decades, the incidence of thyroid carcinoma has been increasingglobally. Data from 2006 to 2012 indicate an annual incidence rate of thyroid cancerof around 5·4% in men and 6·5% in women. Furthermore, with the mean incidence increasing by 6·2% per year, thyroid canceris the fifth most common malignancy diagnosed in women, and the most common cancerin women younger than 25 years. Approximately 37 200 new cases of thyroid cancer were diagnosed in the USA alonein 2009, compared to 56 460 new cases reported only a few years later in 2012. Cases of papillary thyroid carcinoma are mainly responsible for this increased incidence;the rates of other forms of thyroid cancer have remained relatively stable over time.Papillary thyroid carcinoma represents around 90% of all diagnosed thyroid cancers.As of 2017, new diagnoses of thyroid cancer only included 4·4% follicular carcinomas,1·5% Hürthle cell carcinomas, 1·5% medullary carcinomas, and less than 1% anaplasticcarcinomas. Of note, many previous large studies reporting epidemiologic data for thyroid cancerhave originated from the USA; there are few data for the worldwide incidence of thyroidcancer.
