Differentiated thyroid cancer and outcome in iodine deficiency.

Aims: Factors influencing prognosis and long-term outcome of thyroid cancer have been described by several groups. We wished to asses the previously described prognostic factors in a moderately iodine deficient region in Hungary.

Methods: Four hundred and fifty-four out of 492 patients who had surgery for papillary thyroid cancer (PTC, 386 cases) and follicular thyroid cancer (FTC, 106 cases) between 1971 and 1998 were analyzed.

[PET scanning in head and neck cancer].

INTRODUCTION: FDG (fluorine-labeled deoxy-glucose) and 11C-methionine positron emission tomography was evaluated in the diagnostics of head and neck cancer. PET scans were applied for identifying/staging relapse after oncotherapy or searching unknown primary tumor with metastatic lymph nodes of the neck. METHODS: Retrospective analysis of 22 patients examined by 17 (18)FDG and 15 (11)C-methionine PET scan.
