Pituitary Tumors Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Thyrotropin-Producing Tumors Treatment
Standard Treatment Options for Thyrotropin-Producing Tumors
Standard treatment options for thyrotropin-producing tumors include the following:
- Surgery (usually a transsphenoidal approach), with or without adjuvant radiation therapy.[1,2]
- Somatostatin analogues, such as octreotide.[3,4]
Transsphenoidal surgery is the treatment of choice for patients with thyrotropic adenomas. Adjuvant radiation therapy may be employed when surgery is known to be noncurative even if the patient is still euthyroid because relapse is inevitable, and the full effect of radiation therapy requires months or years.
Medical therapy may be required for patients who still have hyperthyroid symptoms despite surgery and external radiation. Somatostatin analogues are the drugs of choice for treatment; however, the efficacy of treatment may wane with time.[1,2,3,4]
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with pituitary tumor. 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.
