Summary
Hürthle cell tumors present a diagnostic challenge with a 26% malignancy rate. Near-total thyroidectomy is recommended for fit patients, with node sampling for potential metastasis, to improve outcomes.
Area of Science:
- Endocrinology
- Oncology
- Surgical Pathology
Background:
- Hürthle cell tumors (HCTs) are rare thyroid neoplasms with variable clinical behavior.
- Management strategies for HCTs remain debated due to limited long-term data.
Purpose of the Study:
- To review a cohort of Hürthle cell tumor patients to inform an optimal treatment policy.
- To assess the incidence of malignancy, multicentricity, and associated thyroid conditions.
Main Methods:
- Retrospective review of 34 patients diagnosed with Hürthle cell tumor between 1971 and 1984.
- Analysis of patient demographics, clinical presentation, surgical management, and outcomes.
Main Results:
- A 26% incidence of malignancy was observed, with one death attributed to anaplastic transformation.
- Multicentric disease occurred in 18% of patients, with half being malignant.
- Contralateral Hürthle cell tumors developed in 12% after lobectomy; 30% had associated thyroid lesions, and 10% had hyperparathyroidism.
Conclusions:
- Near-total thyroidectomy is advocated for fit patients with Hürthle cell tumors.
- Lesser procedures may be suitable for debilitated patients or complex cases.
- Node sampling is recommended for early metastasis detection and improved survival.
