AIM The goal of this study was to estimate the cumulative activity of (131)I to be administered to patients with distant metastases from thyroid carcinoma. METHODS A total of 444 patients were treated from 1953-1994 for distant metastases from papillary and follicular thyroid carcinoma: 223 had lung metastases only, 115 had bone metastases only, 82 had(More)
BACKGROUND It is not clear whether the administration of radioiodine provides any benefit to patients with low-risk thyroid cancer after a complete surgical resection. The administration of the smallest possible amount of radioiodine would improve care. METHODS In our randomized, phase 3 trial, we compared two thyrotropin-stimulation methods (thyroid(More)
CONTEXT Germline mutations in SDHx genes cause hereditary paraganglioma. OBJECTIVE The aim of the study was to assess the indications for succinate dehydrogenase (SDH) genetic testing in a prospective study. DESIGN A total of 445 patients with head and neck and/or thoracic-abdominal or pelvic paragangliomas were recruited over 5 yr in 20 referral(More)
The new WHO classification of gastroenteropancreatic (GEP) neuroendocrine tumors (NET) implies that G3 neoplasms with mitotic index >20 and/or Ki67 index >20% are neuroendocrine carcinomas (NEC), described as poorly differentiated, small or large cell types, by analogy with lung NEC. To characterize the subgroup of non-small-cell-type GEP and thoracic NET(More)
CONTEXT Reliable prognostic factors are needed in papillary thyroid cancer patients to adapt initial therapy and follow-up schemes to the risks of persistent and recurrent disease. OBJECTIVE AND SETTINGS: To evaluate the respective prognostic impact of the extent of lymph node (LN) involvement and tumor extension beyond the thyroid capsule, we studied a(More)
CONTEXT Mitotane is highly effective in the long-term management of Cushing's syndrome but has a slow onset of action. Mitotane combined with fast-acting steroidogenesis inhibitors might avoid the need for emergency bilateral adrenalectomy in patients with severe hypercortisolism. OBJECTIVE Our objective was to assess the efficacy and safety of(More)
UNLABELLED A retrospective study was performed on 101 consecutive medullary thyroid cancer (MTC) patients who underwent at Institut Gustave-Roussy (IGR) total thyroidectomy with central and bilateral lymph node dissection. At histology, lymph node metastases were found in 55% of patients. In sporadic MTC, lymph node metastases were observed in the central(More)
OBJECTIVE To analyze the yield and rate of node metastases (pN1) for prophylactic central (CND) and lateral neck dissection (LND) for papillary thyroid carcinoma, the risk factors for pN1, and outcomes. BACKGROUND Prophylactic CND and LND are not routinely employed. Adjuvant radioiodine treatment may be modulated, however, by surgical staging of the neck.(More)
PURPOSE Because calcitonin level remains elevated after initial treatment in many medullary thyroid carcinoma (MTC) patients without evidence of disease in the usual imaging work-up, there is a need to define optimal imaging procedures. PATIENTS AND METHODS Fifty-five consecutive elevated calcitonin level MTC patients were enrolled to undergo neck and(More)
To assess and compare the performance of CT and 18F-FDG-PET/CT in the evaluation of peritoneal carcinomatosis (PC). Thirty consecutive patients with PC and scheduled for a surgery underwent a CT of the abdomen and pelvis and a whole-body 18F-FDG PET/CT. The extent of PC was assessed precisely using the peritoneal cancer index combining the distribution of(More)
