Câncer da tiróide: aumento na ocorrência da doença ou simplesmente na sua detecção?

Abstract: Não há como negar que estão sendo diagnosticados mais casos e estes estão sendo mais bem tratados (2). A popularização da ultra-sonografi a e da citologia aspirativa por agulha fi na, métodos simples, de custo relativamente baixo, de ampla disponibilidade e grande sensibilidade é seguramente responsável pelo aumento da incidência que vem sendo registrado em todo o mundo. A diminuição da mortalidade se deve à melhora das condições socioeconômicas e de acesso da população ao sistema de saúde, à ampla divulgação … Show more

“…Although the incidence of thyroid cancers has presented a marked increase, the mortality rates have remained stable indicating that a pool of formerly undiagnosed tumors would possibly never present a clinical evolution (Davies & Welch 2006). However, the reasons why DTC incidence has been increasing are still controversial (Ward & Graf 2008). A series of studies have claimed that this was only a matter of diagnosis (Davies & Welch 2006, Grodski et al 2008, Sprague et al 2008, but the increasing incidence does not comprise only tumors less than 1 cm of extent favored by better imaging tests, but also larger tumors, making it difficult to believe that changes in incidence are exclusively due to improvements in diagnosis and health access (Enewold et al 2009).…”

“…Indeed, thyroid cancer is the most common endocrine cancer, with an incidence rate of 7.57 per 100,000 women and 1.49 per 100,000 men in Brazil (10), though recent data indicate an increase in incidence worldwide (2,(11)(12)(13)(14). Interestingly, this increase is not accompanied by a proportional increase in mortality, suggesting the potential diagnosis of earlystage cancer associated with a lower risk of recurrence or the potential occurrence of overdiagnosis, which means diagnosing a disease that would never cause symptoms or death during a patient's expected life span (2,(15)(16)(17)(18).…”

“…The incidence of cancer has grown around the world during the last years mainly due to the large increase in the number of cases of small lesions detected because the aging population is obtaining better access to health care and sensitive diagnostic tools [1]. Although there are lines of evidence that a large number of these small tumors would never become clinically important [2], part of these lesions evolve, and despite the general good prognosis of differentiated thyroid cancer, up to 10–15% of patients have an aggressive form of the disease, which will contribute to the 1,850 deaths from thyroid cancer estimated to occur in 2013 in the USA [3].…”
