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)
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)
PURPOSE Initial lymphoma staging requires bone marrow assessment in aggressive lymphomas. Bone marrow lymphoma infiltration is routinely assessed by bone marrow biopsy (BMB), considered as the "gold standard". The aim of this study was to compare the performance of BMB, whole-body MRI and PET/CT for evaluation of BM infiltration. METHODS Patients with(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)
BACKGROUND No effective standard treatment exists for patients with radioiodine-refractory, advanced differentiated thyroid carcinoma. We aimed to assess efficacy and safety of vandetanib, a tyrosine kinase inhibitor of RET, VEGFR and EGFR signalling, in this setting. METHODS In this randomised, double-blind, phase 2 trial, we enrolled adults (aged ≥18(More)
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)
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)
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)
BACKGROUND Adrenocortical carcinoma is a rare cancer that has a poor response to cytotoxic treatment. METHODS We randomly assigned 304 patients with advanced adrenocortical carcinoma to receive mitotane plus either a combination of etoposide (100 mg per square meter of body-surface area on days 2 to 4), doxorubicin (40 mg per square meter on day 1), and(More)
BACKGROUND Multiple endocrine neoplasia type 2B (MEN 2B) is an exceptional syndrome, for which the optimal age of thyroidectomy is poorly established and the course of medullary thyroid carcinoma (MTC) is ill-defined. PATIENTS All the 18 patients with a MEN 2B syndrome examined at the Institut Gustave Roussy were included in a single-center retrospective(More)
