Newswise — African Americans exhibit a significantly lower rate of thyroid cancer than white Americans, raising some significant questions about whether detection efforts in blacks are insufficient, according to a new study.
The research, first presented at the American Academy of Otolaryngology-Head and Neck Surgery Foundation's Annual Meeting & OTO EXPO in Washington, DC, shows the incidence of thyroid cancer in black Americans is half that of white Americans.
The thyroid cancer trend is contrary to other types of cancers in black Americans, who are more likely than other ethnic groups to develop cancer and die from it. Using the National Cancer Institute's SEER database and the Agency for Healthcare Research & Quality's HCUP database, the authors determined that since 1973, instances of thyroid cancer in whites increased by over 150 percent, while instances among blacks over the same period increased by only 73 percent; it would take an extra 1,800 cases of thyroid cancer a year in blacks to equalize the rates. The study also determined that black patients tend to be diagnosed at an older age and with larger tumors.
Patients diagnosed with thyroid cancer were also less likely to be uninsured, and more likely to live in wealthier areas (based on ZIP codes).
The authors believe that more aggressive detection efforts in blacks could result in increases in diagnoses compared with what is currently being reported. They also suggest that further research in to the genetic and environmental basis for this difference is warranted.
