This is a 2 arms study concerning patients with primary GIST who followed an Imatinib adjuvant treatment for 3 years after surgery and who have a high risk of recurrence.

In the first arm, patients will continue Imatinib treatment for 3 more years, allowing to determine if the continuation of this treatment is efficient for disease control, in terms of Disease Free Survival improvement.

In the second arm, patients will discontinue the Imatinib treatment, as standard practice. This arm will allow to determine if the re-introduction of Imatinib at relapse is still an efficient treatment for the control of disease.
