To evaluate the time needed for TSH elevation (\\> 30 mUI/L) on placebo vs. L-T3.', 'detailedDescription': "Patients with well differentiated thyroid cancer (DTC) need whole-body scintigraphy (WBS) and thyroglobulin (Tg) measurement in order to detect recurrence. Classically, withdrawal from levothyroxine (L-T4) during 4-6 weeks is needed for TSH elevation (\\> 30mUI/L), to allow iodine uptake and Tg production. As a result, patients become hypothyroid with impaired quality of life and a potential for tumour flare-up. Recombinant hTSH before WBS prevents hypothyroidism but is not yet approved for radioiodine treatment and is an expensive therapy. L-T3 substitution during the first 2-3 weeks of withdrawal is an alternative used empirically to prepare patients; however, no data exists to prove its benefit upon reducing hypothyroidism.\n\nObjectives: 1) To compare the hypothyroid state in patients prepared either by placebo or L-T3 following L-T4 withdrawal. 2) To evaluate the time needed for TSH elevation (\\> 30 mUI/L) on placebo vs. L-T3.\n\nMethod: At the time of L-T4 withdrawal or after thyroidectomy, patients with DTC awaiting WBS or radioiodine treatment were randomized in two groups (double-blind): L-T3 (50 mg qd) or an identical placebo for 3 weeks, after which treatment was stopped for 2 weeks. A validated questionnaire of signs and symptoms of hypothyroidism (Billewicz's scale) was administered every 2 weeks until the WBS. TSH, fT4 and fT3 were measured weekly."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients with well-differentiated thyroid cancer, with total thyroidectomy\n* 18 y.o. or older\n\nExclusion Criteria:\n\n* Use of rhTSH for Whole Body Scintigraphy preparation\n* Non stable cardiac arrythmias\n* Any condition impairing TSH elevation(glucocorticoid use, hypopituitarism)\n* Allergy to Liothyronine\n* Inability to give a consent'}, 'identificationModule': {'nctId': 'NCT00223158', 'briefTitle': 'Evaluation Study of L-T3 Utility in the Follow-up of Patients With Thyroid Cancer', 'organization': {'class': 'OTHER', 'fullName': 'Université de Sherbrooke'}, 'officialTitle': 'L-T3 Preparation for I131 Whole Body Scintigraphy: A Randomized Controlled Trial', 'orgStudyIdInfo': {'id': 'CRC 03-52-R1'}}, 'armsInterventionsModule': {'interventions': [{'name': 'Liothyronine', 'type': 'DRUG'}]}, 'contactsLocationsModule': {'locations': [{'zip': 'J1H 5N4', 'city': 'Sherbrooke', 'state': 'Quebec', 'country': 'Canada', 'facility': 'Centre Hospitalier Universitaire de Sherbrooke', 'geoPoint': {'lat': 45.40008, 'lon': -71.89908}}], 'overallOfficials': [{'name': 'Rébecca Leboeuf, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Université de Sherbrooke'}, {'name': 'Marie-France Langlois, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Université de Sherbrooke'}, {'name': 'Patrice Perron, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Université de Sherbrooke'}, {'name': 'André Carpentier, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Université de Sherbrooke'}, {'name': 'Jean Verreault, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Université de Sherbrooke'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Patrice Perron', 'class': 'OTHER'}, 'collaborators': [{'name': 'Theramed co.', 'class': 'UNKNOWN'}], 'responsibleParty': {'type': 'SPONSOR_INVESTIGATOR', 'investigatorTitle': 'MD', 'investigatorFullName': 'Patrice Perron', 'investigatorAffiliation': 'Université de Sherbrooke'}}}}
