Increased trend of thyroid cancer in childhood over the last 30 years in EU countries: a call for the pediatric surgeon.

UNLABELLED

Given the increasing incidence of thyroid cancer cases affecting the pediatric population in Europe, an epidemiological analysis of the available data is essential in order to update standards of care and recommend diagnostic and therapeutic strategies coherent to the new epidemiological trend. An observational study was conducted, considering the time interval 1991-2012, acquiring data collected by the International Agency for Research on Cancer (IARC) through the "Cancer Incidence in 5 continents plus" (CI5 plus) project and dividing patients into four groups of age (0-4, 5-9, 10-14, 15-19 years old). Data retrieved were compared to the latest report from Global Cancer Observatory, collected through the GLOBOCAN 2020 project, dividing patients in two groups: age 10-14, 15-19. Our findings highlighted an increasing prevalence of thyroid cancer rates in patients aged from 10 to 15 years old and from 15 to 19 years old, mainly in the female population, in Belarus (from 1991 to 2007), Cyprus, and Italy (from 2008 to 2012). Moreover, a further increase in incidence was highlighted in Italy according to data from GLOBOCAN 2020, with respect to other European countries.

CONCLUSION

An increasing prevalence of thyroid cancer is seen in age groups 10-19. Further research is required to understand the underlying cause and concomitantly identify the most proper screening and diagnostic techniques of thyroid nodules. Indeed, this is crucial to reach optimal surgical standards and better prognosis, possibly with more conservative approaches and maybe less postoperative complications.

WHAT IS KNOWN

• Thyroid cancer is the 4th most common malignancy in children.

WHAT IS NEW

• In the last decades, an increasing pattern has been recorded. • In the US, it has outlined breast cancers as the most common cancer in females.
