A Study of c-Kit Mutation as MRD in Acute Myeloid Leukemia

C-Kit is involved in an essential pathway of disease occurrence and is closely related to the poor prognosis of patients. However, the clinical significance of c-Kit mutation as molecular MRD monitoring is still unclear. What are the differences and advantages of using c-Kit mutation as MRD in prognostic assessment compared with other MRDs (MFC or RUNX1::RUNX1T1) widely used today? Existing data suggest that patients with one positive and one negative MRD results obtained by two different techniques have a higher risk of recurrence than patients with two negative MRD results but a lower risk of recurrence than patients with two positive MRD results. Therefore, can combining multiple MRD markers, including c-Kit mutations, overcome the shortcomings of a single molecular marker as MRD monitoring? Therefore, this project intends to confirm the clinical significance of quantitative detection of c-Kit mutation as MRD in acute myeloid leukemia.

Safety and Efficacy of Avapritinib in Relapsed or Refractory Pediatric CBF-AML With KIT Mutation

The purpose of this study is to evaluate the efficacy and safety of avapritinib in relapsed or refractory pediatric core binding factor acute myeloid leukemia with KIT mutation.

Efficiency of Imatinib Treatment After 10 Years of Treatment in Patients With Gastrointestinal Stromal Tumours (GIST) (Gist-Ten)

This is a 2 arms study concerning patients under imatinib treatment for at least 10 years of treatment with locally advanced/metastatic GIST. In the first arm, patients will discontinue Imatinib treatment. This arm will allow to determine if the re-introduction of Imatinib at relapse is still an efficient treatment for the control of disease. In the second arm, patients will continue Imatinib treatment, allowing to determine if the continuation of this treatment is efficient for disease control, by the rate of non-progression disease.
