The study participants are required to have a histologically verified GIST with a high risk of GIST recurrence despite complete removal of all macroscopic GIST tissue at surgery. The high/very high risk of recurrence is defined as one of the following: 1) the largest tumor diameter is over 10 cm; 2) the mitosis count is high (over 10 mitoses per 50 high power microscope fields, HPFs); 3) the largest tumor diameter over 5 cm and the mitosis count is over 5/50 HPFs; 4) tumor spillage has taken place into the abdominal cavity at the time of surgery or following spontaneous tumor rupture. All study participants will receive imatinib 400 mg/day orally, but the duration of imatinib administration will be determined randomly (either for 12 or for 36 months). The study participants will be followed up using blood tests and computed tomography (or MRI) of the abdomen. The computed tomography examinations will be performed at 6 month intervals for a median of 5 years. A total of 280 patients will be entered into the study. The study hypothesis is that adjuvant imatinib may prevent some of the GIST recurrences, and that there may be a difference in the rate of GIST recurrence between the two groups.', 'detailedDescription': 'This is an open-label, randomized, prospective, phase III, multicenter study carried out in the Nordic countries and in Germany. Following macroscopically complete surgery, the study participants will be allocated to receive imatinib either for 12 or for 36 months. At randomization, the patients are stratified into 2 strata: 1) local disease (1 GIST tumor); 2) intra-abdominal implants or resectable intra-abdominal/hepatic metastases, or intra-abdominal spillage is present, or R1 surgery has been carried out (microscopic disease has been left behind). The imatinib dose is 400 mg/day administered with food. Imatinib dose adjustments are made as per protocol.\n\nMedical history, current medication, weight, height, and ECOG performance status are recorded prior to study entry. Physical examination, blood cell counts, blood biochemistry, pregnancy test, chest X-ray or CT, and CT or MRI of the abdomen and pelvis are carried out/measured prior to study entry. FDG-PET is an optional staging examination. Research serum samples are collected for banking prior to initiating imatinib and at 6-month intervals during the study. Tumor tissue is reviewed centrally to confirm the histological diagnosis of GIST, and KIT and PDGFRA gene mutation analyses will be performed from stored GIST tissue.\n\nThe study participants are monitored during adjuvant treatment and following adjuvant treatment. Physical examination, weight and ECOG performance status are assessed at 4- to 26-week intervals. Adverse events are collected using structured forms at the times of the evaluation visits. Blood cell counts and blood biochemistry are measured at 2- to 6-week intervals during imatinib therapy, and at 6-month intervals following completion of adjuvant therapy. CT or MRI examinations of the abdomen and pelvis are performed at 6-month intervals during the study.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age 18 or older\n* Histologically documented diagnosis of GIST\n* Resectable GIST\n* GIST removed at open surgery\n* Immunohistochemical documentation of GIST (immunostaining for KIT/CD117)\n* High risk of tumor recurrence as defined as one of the following: 1) the largest tumor diameter greater than 10.0 cm (measured by a pathologist, with any mitotic count); 2) mitotic count over 10 mitoses per 50 high power fields (HPFs) (with any tumor size); the largest tumor diameter larger than 5.0 cm and the mitotic count is over 5/50 HPFs; 4) tumor spillage into the abdominal cavity at surgery (or tumor rupture).
