  abstract  = {Objective: The objective of this study was to study recurrence in patients with differentiated thyroid carcinoma who after initial therapy consisting of total thyroidectomy and I-131 ablation, were cured defined as a negative TSH-stimulated Tg-levels and a negative I-131 whole body scan (WBS) at the first follow-up after ablation. Methods: Retrospective data for differentiated thyroid carcinoma patients from three university hospitals were pooled. Out of 1993 patients, 526 cured patients were included. All patients received at least one more TSH-stimulated WBS and Tg-measurement within 5 years after initial treatment. Results: 12 patients (2.1\%) developed a recurrence after an average interval of 35 months (range: 12-59 months) following administration I-131 ablation. Overall disease-free survival according to the method of Kaplan-Meier was 96.6\%. There was no difference in disease-free survival between high- and low-risk patients (p=0.61). Recurrence was first discovered by Tg-measurement during levothyroxin therapy in 7 patients, and by TSH-stimulated Tg-measurement in 5 patients. I-131 WBS did not contribute to the detection of recurrences. Multivariate analysis showed that age TNM-stage (p=0.015) and histology (p=0.032) were independent predictors of disease-free survival. Conclusion: Recurrence is a rare event in patients with DTC who received total thyroidectomy with subsequent I-131 ablation, and who had a negative first follow-up TSH-stimulated I-131 WBS and negative concurrent Tg. In the study population there were no recurrences after more than 5 years of follow-up.},

  abstract  = {In der vorliegenden retrospektiven Analyse wurden Prognosefaktoren des differenzierten Schilddr{\"u}senkarzinomes untersucht anhand eines Patientenkollektiv von 1174 Patienten, die im Zeitraum von 01.01.1980 bis 31.12.2004 an der Klinik und Poliklinik f{\"u}r Nuklearmedizin der Universit{\"a}t W{\"u}rzburg eine Behandlung erhielten bzw. betreut wurden. Analysiert wurden sowohl tumorbezogene Prognosefaktoren wie Histologie, Tumorstadien, Lymphknotenstatus und Fernmetastasierung, zudem patientenspezifische Faktoren wie Alter und Geschlecht. Bez{\"u}glich dieser Prognosefaktoren konnten wir die Daten fr{\"u}herer Jahre am Patientengut der W{\"u}rzburger nuklearmedizinischen Klinik best{\"a}tigen. Außerdem wurde die Auswirkung auf das krankheitsfreie {\"U}berleben in Abh{\"a}ngigkeit der postoperativen Tumorfreiheit und nach einer erfolgten Radioiodtherapie untersucht. Die Ergebnisse werden kritisch in den Kontext der aktuellen Studienlage gestellt.},
