U.S. Incidence of Thyroid Cancer Plateaued in 2009

From 2009 to 2016, the prevalence of thyroid cancer reached a plateau and possibly started to decline, consistent with a studies letter published in the Dec. 24/31 trouble of the Journal of the American Medical Association.

Ann E. Powers, from the Icahn School of Medicine at Mount Sinai in New York City, and colleagues examined trends in age-adjusted thyroid most cancers prevalence from 1992 to 2016 inside the Surveillance, Epidemiology, and End Results thirteen registry.

The researchers discovered that from 1992 to 2009, there has been an increase in thyroid most cancers prevalence within the United States from five.7 to 13.8 according to 100,000; the best annual percent change (APC; 6.6 percentage; 95 percentage confidence interval [CI], 6.2 to 7.0 percent) turned into from 1998 to 2009. From 2009 to 2014, the price of growth slowed significantly (incidence, thirteen.eight to 14.7 in keeping with 100,000; APC, 2.0 percentage; 95 percent CI, 0.3 to 3.7 percentage). The prevalence of thyroid most cancers has been stable seeing that 2014 (14.7 to 14.1 in keeping with 100,000; APC, −2.four percent; 95 percentage CI, −7.5 to 3.1 percentage). From 1992 to 2009, the prevalence of subcentimeter thyroid cancers elevated regularly from 1.2 to 4.7 according to 100,000, with the greatest APC from 1996 to 2009 (9.1 percent; 95 percentage CI, 8.four to 9.eight percentage). From 2009 to 2013, the trend stabilized (incidence, four.7 to five.three per 100,000; APC, 2.9 percent; 95 percent CI, −2.5 to eight.6 percentage) and then decreased from 2013 to 2016 (incidence, five.3 to four.7 in keeping with 100,000; APC, −3.7 percent; 95 percent CI, −8.7 to 1.7 percentage).

“Although a real decline within the prevalence of thyroid cancer is a possible reason behind these converting developments, less extensive workup of thyroid nodules is more likely,” the authors write.
