Giving imatinib mesylate after surgery may kill any remaining tumor cells. It is not yet known whether imatinib mesylate is more effective than observation only in treating gastrointestinal stromal tumor.\n\nPURPOSE: This randomized phase III trial is studying imatinib mesylate to see how well it works compared to observation only in treating patients who have undergone surgery for localized gastrointestinal stromal tumor.', 'detailedDescription': 'OBJECTIVES:\n\nPrimary\n\n* Assess whether there is a difference in overall survival between intermediate and high-risk localized GIST patients undergoing complete surgery alone and those undergoing complete surgery plus adjuvant imatinib mesylate 400 mg daily for two years Secondary\n* Assess whether there is a difference in relapse-free survival and relapse-free interval between GIST undergoing complete surgery alone and those undergoing surgery + adjuvant Imatinib mesylate 400 mg daily for two years.\n* Determine the safety of this drug in these patients.\n\nOUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified according to participating center, risk category (high vs intermediate), tumor site (gastric vs other), and resection level (R0 vs R1).\n\n* Arm I: Patients receive adjuvant oral imatinib mesylate once daily for 2 years in the absence of disease progression or unacceptable toxicity.\n* Arm II: Patients are observed (without receiving further antitumoral therapy) every 3 months for 2 years.\n\nAfter completion of study treatment, patients in arm I are followed every 3 months for 2 years. All patients are then followed every 4 months for 3 years and at least annually thereafter.\n\nPROJECTED ACCRUAL: A total of 900 patients will be accrued for this study within 3.5 years.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '120 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'DISEASE CHARACTERISTICS:\n\n* Histologically confirmed gastrointestinal stromal tumor\n\n * Localized disease\n* Meets 1 of the following criteria:\n\n * At high-risk of relapse, defined by 1 of the following criteria:\n\n * Tumor size \\> 10 cm\n * Mitotic rate \\> 10/50 high-power field (HPF)\n * Tumor size \\> 5 cm AND mitotic rate \\> 5/50 HPF\n * At intermediate-risk of relapse, defined by 1 of the following criteria:\n\n * Tumor size \\< 5 cm AND mitotic rate 6-10/50 HPF\n * Tumor size 5-10 cm AND mitotic rate \\< 5/50 HPF\n* Tumor must stain positive for Kit (CD117) by polyclonal DAKO antibody staining\n* Must have undergone complete resection of the primary tumor at least 2 weeks, but no more than 3 months, before study entry\n\n * Meets criteria for 1 of the following resection levels:\n\n * R0 (clear margins)\n * R1, defined by 1 of the following criteria:\n\n * Margins of resection are contaminated by tumor, but no macroscopic tumor is left behind\n * Intraoperative tumor rupture\n * Shelling-out procedure\n * Endoscopic maneuver\n * No residual macroscopic disease after surgery\n\n * Regional positive lymph nodes allowed provided they have been macroscopically excised\n* No distant metastases\\*, including any of the following:\n\n * Peritoneal lesion not contiguous to the primary tumor\n * Liver metastases\n * Hemoperitoneal metastases NOTE: \\*Even if a complete resection (R0) was performed\n\nPATIENT CHARACTERISTICS:\n\nAge\n\n* 18 and over\n\nPerformance status\n\n* WHO 0-2\n\nLife expectancy\n\n* Not specified\n\nHematopoietic\n\n* Absolute neutrophil count ≥ 1,500/mm\\^3\n* Platelet count ≥ 100,000/mm\\^3\n* Hemoglobin ≥ 9 g/dL (transfusions allowed)\n\nHepatic\n\n* Bilirubin ≤ 1.5 times upper limit of normal (ULN)\n* AST or ALT ≤ 2.5 times ULN\n* No uncontrolled liver disease\n* No chronic viral hepatitis at risk of reactivation\n\nRenal\n\n* Creatinine \\< 1.5 times ULN\n* No uncontrolled chronic renal disease\n\nCardiovascular\n\n* No New York Heart Association class III-IV cardiac disease\n* No congestive heart failure\n* No myocardial infarction within the past 2 months\n\nOther\n\n* Not pregnant or nursing\n* Negative pregnancy test\n* Fertile patients must use effective contraception during and for up to 3 months after study participation\n* No uncontrolled diabetes\n* No uncontrolled active infection\n* No HIV infection\n* No psychological, familial, sociological, or geographical condition that would preclude study compliance or participation\n* No other severe and/or uncontrolled medical disease\n* No other malignancy within the past 5 years except adequately treated basal cell or squamous cell skin cancer or carcinoma in situ of the cervix\n\nPRIOR CONCURRENT THERAPY:\n\nBiologic therapy\n\n* No other prior molecular targeted or biologic therapy\n* No concurrent filgrastim (G-CSF) or sargramostim (GM-CSF) to support blood counts\n* No concurrent anticancer biologic agents\n\nChemotherapy\n\n* No prior chemotherapy for gastrointestinal stromal tumors\n* No concurrent anticancer chemotherapy\n\nEndocrine therapy\n\n* Not specified\n\nRadiotherapy\n\n* No prior radiotherapy\n* No concurrent anticancer radiotherapy\n\nSurgery\n\n* See Disease Characteristics\n* Prior non-curative surgery allowed (e.g., surgery with main diagnostic intent or emergency surgery with symptomatic intent)\n\nOther\n\n* No prior imatinib mesylate\n* No prior randomization to this study\n* No concurrent therapeutic anticoagulation with coumarin derivatives\n\n * Concurrent therapeutic low-molecular weight heparin or mini-dose coumarin derivatives (equivalent to oral warfarin 1 mg/day) allowed for prophylaxis of central venous catheter thrombosis\n* No other concurrent antitumoral therapy\n* No other concurrent anticancer agents\n* No other concurrent investigational drugs'}, 'identificationModule': {'nctId': 'NCT00103168', 'briefTitle': 'Imatinib Mesylate or Observation Only in Treating Patients Who Have Undergone Surgery for Localized Gastrointestinal Stromal Tumor', 'organization': {'class': 'NETWORK', 'fullName': 'European Organisation for Research and Treatment of Cancer -
