Giving chemotherapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether chemotherapy is more effective when given alone or together with surgery in treating patients with colorectal cancer.\n\nPURPOSE: This randomized phase II/III trial is studying how well chemotherapy works and compares it with surgery followed by chemotherapy in treating patients with metastatic colorectal cancer that can not be removed by surgery.', 'detailedDescription': 'OBJECTIVES:\n\n* To determine whether overall survival is improved in patients with asymptomatic, unresectable metastatic colorectal cancer treated with chemotherapy alone versus surgery followed by chemotherapy.\n\nOUTLINE: This is a multicenter study. Patients are randomized to 1 of 2 treatment arms.\n\n* Arm I (control arm): Patients receive systemic chemotherapy according to standard local practice. Patients who develop symptoms from their primary tumor receive treatment as required including surgery, if indicated.\n* Arm II (experimental arm): Patients undergo surgery at the discretion of the surgeon. Beginning 8 weeks after completion of surgery, patients receive chemotherapy according to standard local practice.\n\nPatients complete quality-of-life questionnaires (EQ-5D) at baseline and then periodically during and after completion of study treatment.\n\nAfter completion of study treatment, patients are followed every 3 months.\n\nPeer Reviewed and Funded or Endorsed by Cancer Research UK'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'DISEASE CHARACTERISTICS:\n\n* Histologically or cytologically confirmed colorectal cancer\n\n * Metastases which are unresectable at presentation\n* No known unresectable primary tumor on CT/MRI scan\n* Primary tumor does not require immediate or emergency intervention including surgery, radiotherapy, laser, or stenting\n\n * Patients who are treated with colonic stents are eligible\n* No unequivocal extensive peritoneal metastases\n\nPATIENT CHARACTERISTICS:\n\n* WHO performance status 0-1\n* Must be fit for systemic chemotherapy and surgery\n* Hemoglobin \\> 10.0 g/dL\n* WBC \\> 3.0 x 10\\^9/L\n* Platelet count \\> 100 x 10\\^9/L\n* Bilirubin \\< 25 μmol/L\n* GFR \\> 50 mL/min\n* Not pregnant or nursing\n* Negative pregnancy test\n* Fertile patients must use effective contraception during and for 3 months (female) or up to 2 months (male) after completion of study therapy\n* No history of malignant disease within the past 5 years except for nonmelanomatous skin cancer or carcinoma in situ of the cervix\n* No serious medical co-morbidity (e.g., uncontrolled inflammatory bowel disease, uncontrolled angina, recent \\[within the past 6 months\\] myocardial infarction, or another serious medical condition) judged to compromise ability to tolerate chemotherapy and/or surgery\n\nPRIOR CONCURRENT THERAPY:\n\n* See Disease Characteristics\n* Concurrent participation in a trial of chemotherapy, if eligible, allowed\n* Concurrent short-course radiotherapy for operable rectal cancer allowed'}, 'identificationModule': {'nctId': 'NCT01086618', 'briefTitle': 'Chemotherapy With or Without Surgery in Treating Patients With Metastatic Colorectal Cancer That Cannot Be Removed by Surgery', 'organization': {'class': 'NIH', 'fullName': 'National Cancer Institute (NCI)'}, 'officialTitle': 'A Randomized Trial of Initial Surgery in Advanced Asymptomatic Colorectal Cancer Patients Receiving Chemotherapy for Metastatic Disease', 'orgStudyIdInfo': {'id': 'CDR0000667364'}, 'secondaryIdInfos': [{'id': 'UCL-08/0079'}, {'id': 'UCL-ISAAC'}, {'id': 'ISRCTN10963271'}, {'id': 'EU-21008'}, {'id': 'CRUK-C32436/A10431'}, {'id': 'EUDRACT-2008-005911-16'}, {'id': 'MREC-09/H1102/60'}, {'id': 'NCRI-UCL-08/0079'}]}, 'armsInterventionsModule': {'interventions': [{'name': 'systemic chemotherapy', 'type': 'DRUG'}, {'name': 'adjuvant therapy', 'type': 'PROCEDURE'}, {'name': 'quality-of-life assessment', 'type': 'PROCEDURE'}, {'name': 'therapeutic conventional surgery', 'type': 'PROCEDURE'}]}, 'contactsLocationsModule': {'locations': [{'zip': 'NW1 2BU', 'city': 'London', 'state': 'England', 'country': 'United Kingdom', 'facility': 'University College Hospital', 'geoPoint': {'lat': 51.50853, 'lon': -0.12574}}], 'overallOfficials': [{'name': 'Austin Obichere, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University College London Hospitals'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University College London Hospitals', 'class': 'OTHER'}}}}
