Gastrointestinal Stromal Tumors Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Metastatic or Recurrent Gastrointestinal Stromal Tumors
The first two indications (1 and 2) identify subsets of patients with advanced disease that are selected for relative disease stability. Therefore, the favorable outcomes that have been noted in case series may be principally the result of selection bias rather than true benefit from surgery. Because the median time to the development of secondary resistance to imatinib has been found to be about 2 years, it has been suggested that surgery for metastatic or recurrent disease in patients on imatinib/sunitinib be performed before 2 years. Most experts would recommend considering surgery after 6 to 12 months of disease stability with TKI therapy. Drug therapy may be continued after surgery. Patients with generalized disease progression are managed medically and may be enrolled in clinical trials.
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with gastrointestinal stromal 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.
