Lancet Sub-Journal: Over 80% of thyroid cancers in my country are overdiagnosed!

Globally, the incidence of thyroid cancer has risen sharply in the past three decades , especially among young adults and even adolescents.

The incidence of thyroid cancer has risen sharply in the past three decades.

There may be an over-diagnosis problem behind the “high incidence” of diagnosing thyroid cancer-that is, a diagnosed cancer may not cause symptoms or death in a lifetime.

In March, French cancer surveillance at Lyon IARC (IARC) published in the " Lancet Diabetes research on and Endocrinology" (The Lancet Diabetes & Endocrinology) shows across 25 countries / regions by histologic classification The data shows that the incidence of thyroid cancer, especially papillary subtype cancer, has increased rapidly in recent years, and the analysis is caused by excessive screening for the disease .

The incidence of Lancet diabetic thyroid cancer, especially papillary subtype cancer, has increased rapidly in recent years, and the analysis is due to excessive screening for the disease .

In some countries, overdiagnosis of thyroid cancer accounts for 60-90% of confirmed cases.

A recent study jointly conducted by IARC and Sun Yat-sen University Cancer Center has shown that the age-standardized incidence rates for women and men are 16.

There is about a 45-fold difference between the regions with the lowest and highest incidence.

The incidence of females ranges from 0.

An obvious epidemiological feature of the overdiagnosis of thyroid cancer observed on a global scale is that the increase in incidence is usually accompanied by a change in the age of diagnosis: the peak appears at around middle age (35-64 years) , not like 20 It appeared in old age (65-84 years) before the 1980s.

The peak appears around middle age (35-64 years old) The peak appears around middle age (35-64 years old)

In fact, in 2008-2012, when comparing the incidence rate with the age at diagnosis, many regions in China followed this pattern, similar to an "inverted U shape.

At the same time, the researchers calculated the overdiagnosis based on the difference between the observed and expected age-specific incidence.

During 2008-12, 83.

In summary, over-diagnosis of thyroid cancer is an example of medical waste, which is a major challenge to improve the equality of medical services and reduce government expenditures at the same time.
