Gastrointestinal Stromal Tumors Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Resistant / Refractory Gastrointestinal Stromal Tumors
Eventual development of resistance to both imatinib and sunitinib is nearly universal. There is no standard therapy when this occurs, and patients should be considered for investigational therapy. Additional oral TKIs are under investigation. For example, in a preliminary case series, nilotinib has shown biological activity, with unknown impact on survival.
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...
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.
