Parathyroid Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Metastatic Parathyroid Cancer
Metastatic disease can appear shortly after the initial diagnosis and operation or for up to 20 years later. Because of the difficulty in making a histologic diagnosis, the appearance of recurrent or metastatic disease in a patient previously operated on for hypercalcemia can be the first indicator that the tumor was malignant. Approximately 50% of the patients who experience recurrence will have distant metastases. The most common site of distant metastasis is the lung.[4,5] Some patients experience years of survival even after the diagnosis of distant metastases. Aggressive surgical resection has been associated with a 30% long-term survival in retrospective series.[3,6] (Refer to the PDQ summary on Hypercalcemia for more information.)
A link to a list of current clinical trials is included for each treatment section. For some types or stages of cancer, there may not be any trials listed. Check with your doctor for clinical trials that are not listed here but may be right for you.
Monoclonal Gammopathy of Undetermined Significance
Treatment of monoclonal gammopathy of undetermined significance (MGUS) is usually watchful waiting. Regular blood tests to check the level of M protein in the blood and physical exams to check...
Chemotherapy. Anecdotal reports show that short-term remissions with chemotherapy are possible.[5,10]
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with metastatic parathyroid cancer. 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.
