Increasing incidence and characteristics of differentiated thyroid cancer in Huntington, West Virginia.
Since 1985, we have observed an increasing number of differentiated thyroid cancer cases in Huntington, West Virginia. We describe tumor incidence, patient and tumor characteristics, treatment modalities, and tumor recurrence and death. One hundred seventeen patients with differentiated thyroid cancer were identified between 1976 and 1999. Data were collected from patient records in our practice and the tumor registries at the three hospitals serving our community. The annual incidence of differentiated thyroid cancer increased significantly from fewer than 3 cases per 100,000 prior to 1996 to 9.4 cases per 100,000 in 1999. The median age at diagnosis was 49 years (range, 16-80). The median tumor size was 2.5 cm (range, 1.2-10). Forty-seven percent of the patients had bilateral disease, 28% had three or more tumors, 44% had thyroid capsular invasion, and 16% had gross extrathyroid invasion at surgery. Twenty-two percent had cervical lymph node involvement and 9% had distant metastases at diagnosis. During 1-month to 23-year follow-up, 11% had recurrence, and 5% died of thyroid cancer. In summary, differentiated thyroid cancer has increased dramatically in our community. The tumors appear to be aggressive at diagnosis as reflected by the high percentage of tumors with bilateral, multicentric, and locally invasive disease.[1]References
