Overview
Staging
- No generally accepted staging system is available for anaplastic thyroid cancer. All patients are considered to have stage IV disease.
- Undifferentiated (anaplastic) carcinomas are highly malignant cancers of the thyroid. They may be subclassified as small cell or large cell carcinomas. Both grow rapidly and extend to structures beyond the thyroid. Both small cell and large cell carcinomas present as hard, ill-defined masses, often with extension into the structures surrounding the thyroid. Small cell anaplastic thyroid carcinoma must be carefully distinguished from lymphoma. This tumor usually occurs in an older age group and is characterized by extensive local invasion and rapid progression. Five-year survival with this tumor is poor. Death is usually from uncontrolled local cancer in the neck, usually within months of diagnosis.[1]
