What is treatment for medullary carcinoma?

MANAGEMENT OF PERSISTENT OR RECURRENT MEDULLARY THYROID CARCINOMA

Is medullary carcinoma curable?

Together, you and your doctor will develop a treatment plan for medullary carcinoma. Some doctors feel that a true medullary carcinoma may only require surgery without any additional (or adjuvant) treatments, such as chemotherapy or radiation therapy.

How does medullary carcinoma start?

Medullary thyroid cancer starts as a growth of abnormal cancer cells within the thyroid. These special cells are the parafollicular C cells. In the hereditary form of medullary thyroid cancer, the growth of these cells is due to a mutation in the RET gene which was inherited.

Is medullary carcinoma aggressive?

Medullary thyroid cancer is a rare aggressive type of thyroid neoplasia. Significant predictors for MTC are age, gender, clinical presentation, TNM stage, distant metastases and extent of thyroidectomy.

What clinical management or treatment is suggested for MTC?

Doxorubicin (Adriamycin) and dacarbazine (DTIC) are the two agents with the most extensive track record, and dacarbazine is currently recommended as a treatment option for patients with disseminated, symptomatic disease. Doxorubicin was first tested in MTC patients in the 1970s.
