Summary
The prevalence of thyroid cancer occurring with hyperthyroidism is significant. Careful diagnosis is essential to exclude thyroid cancer in hyperthyroid patients.
Area of Science:
- Endocrinology
- Oncology
- Surgical Pathology
Background:
- Hyperthyroidism is a common endocrine disorder.
- Thyroid cancer incidence is increasing globally.
- Co-occurrence of these conditions requires investigation.
Purpose of the Study:
- To evaluate the prevalence of thyroid cancer in patients with hyperthyroidism.
- To determine the incidence of hyperthyroidism in patients with thyroid cancer.
Main Methods:
- Retrospective study of 394 hyperthyroid patients and 245 thyroid cancer patients.
- Data collected from January 1983 to June 1998.
- Analysis of coincidental diagnoses.
Main Results:
- Thyroid cancer and hyperthyroidism coincided in 12 patients.
- Incidence of thyroid cancer in hyperthyroidism was 3.0%.
- Incidence of hyperthyroidism in thyroid cancer was 4.9%.
Conclusions:
- The prevalence of co-occurring thyroid cancer and hyperthyroidism is notable.
- Exclusionary diagnostics for thyroid cancer are crucial in hyperthyroid patients.
