Medullary Thyroid Cancer

continued...

Overall survival (OS) was not different at 24 months; longer follow-up will be required since only 47 patients had died at the time of analysis, and there was a crossover to the study drug on progression from placebo, making analysis of OS problematic. Vandetanib has significant side effects, including diarrhea, rash, hypertension, and QT prolongation. Quality of life was not formally assessed in this trial.[9]

Palliative chemotherapy has been reported to produce occasional responses in patients with metastatic disease.[10,11,12,13] No single drug regimen can be considered standard. Some patients with distant metastases will experience prolonged survival and can be managed expectantly until they become symptomatic.

Current Clinical Trials

Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with thyroid gland medullary carcinoma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

General information about clinical trials is also available from the NCI Web site.
