Feasibility and benefit of fluorine 18-fluoro-2-deoxyglucose-guided surgery in the management of radioiodine-negative differentiated thyroid carcinoma metastases.

Background: Fluorine 18-fluoro-2-deoxyglucose (FDG) positron emission tomography ((18)F-FDG PET) can be used to visualize metastases in patients with differentiated thyroid carcinoma that does not take up radioiodine ((131)I). This study was aimed at evaluating the feasibility of (18)F-FDG radio-guided surgery in patients with radioiodine-negative differentiated thyroid cancer.

Methods: Ten patients received a mean activity of 265 MBq of (18)F-FDG 30 minutes before operation.

[Complications of Bricker ileal conduit urinary diversion: analysis of a series of 246 patients].

Objective: The objective of this retrospective study was to evaluate the mortality and early and late morbidities of Bricker ileal conduit urinary diversion.

Patients And Methods: Between January 1990 and December 2002, 246 Bricker ileal conduit urinary diversion was performed in our centre in 164 males (67%) and 82 females (33%) with a mean age of 64 years (range: 9 to 90 years). Bricker diversion was performed in 73.

Management and prognosis of metastases to the thyroid gland.

Background: Intrathyroid metastases (ITM) of extrathyroid cancer are rare and have a poor prognosis. The aim of this work was to identify the sites of primary cancers and the treatment and prognosis of these lesions.

Study Design: This retrospective study was carried out on patients treated between 1982 and 2002 in the surgical departments of the University hospitals of Poitiers, Limoges, Tours, and Nantes, France.

Elevated (> or = 10%) MIB-1 proliferative index correlates with poor outcome in gastric stromal tumor patients: a study of 35 cases.

Mitotic activity and tumor size are currently regarded as the most powerful prognostic indicators for patients with gastrointestinal stromal tumor (GIST). This retrospective study evaluated the prognostic accuracy of MIB-1 proliferative index (PI) in combination with these two indicators in 35 GIST patients. Within a high-risk group, determined initially by tumor size and mitotic count, overall survival was significantly shorter for patients whose tumors had PI > or = 10% MIB-1 positive cells.
