The thyroid cancer recurrence rate is reported to range from 7% to 14%. Recurrence is usually detected within the first decade after the initial disease diagnosis. Large lymph node metastasis is considered the strongest predictor for thyroid cancer recurrence. Post-treatment surveillance for recurrent disease depends on the cancer type and staging.
Thyroid scan. A thyroid scan using a radioactive iodine uptake test can be used in viewing the thyroid. [20] A scan using iodine-123 showing a hot nodule, accompanied by a lower than normal TSH, is strong evidence that the nodule is not cancerous, as most hot nodules are benign. [21]
Poorly differentiated thyroid carcinoma is malignant neoplasm of follicular cell origin showing intermediate histopathological patterns between differentiated and undifferentiated thyroid cancers. [ 1 ]
The MACIS system of estimating the prognosis of papillary thyroid cancer was developed by Clive S. Grant at the Mayo Clinic and was based on careful evaluation of a large group of patients. It is probably the most reliable staging method available. [35]
Squamous-cell carcinoma of the thyroid is biologically aggressive malignant neoplasm which is associated with rapid growth of neck mass followed by infiltration of thyroid-adjacent structures. Patients usually demonstrate dysphagia , dyspnea and voice changes, as well as local pain in the neck.
Medullary thyroid cancer is a form of thyroid carcinoma which originates from the parafollicular cells (C cells), which produce the hormone calcitonin. [1] Medullary tumors are the third most common of all thyroid cancers and together make up about 3% of all thyroid cancer cases. [2] MTC was first characterized in 1959. [3]
Anaplastic thyroid cancer (ATC), also known as anaplastic thyroid carcinoma, is an aggressive form of thyroid cancer characterized by uncontrolled growth of cells in the thyroid gland. This form of cancer generally carries a very poor prognosis due to its aggressive behavior and resistance to cancer treatments. [1] The cells of anaplastic ...
The prognosis of thyroid cancer is related to the type of cancer and the stage at the time of diagnosis. For the most common form of thyroid cancer, papillary, the overall prognosis is excellent with 97%, 95%, and 90% 10, 15 and 20 year overall survival respectively. [58] The 5 year survival of all thyroid cancers, with treatment, is 98%. [10]
