Clinical course and treatment of patients with differentiated

Abstract

The aim of the study was to analyze the clinical course and therapy in patients with differentiated thyroid carcinoma (DTC) diagnosed in Poland within the year 1995. The group of 478 patients with thyroid cancer (57.7% of all thyroid cancer cases diagnosed this year in Poland) was analyzed. Patients were diagnosed or treated in Maria Skłodowska-Curie Memorial Cancer Center and Institute of Oncology, Gliwice Branch. Detailed analysis was performed in 352 patients with DTC who were treated by surgery. 292 patients (60%) received adjuvant radioiodine therapy. Hormonal (L-thyroxine) treatment was administered to all patients. In 37 patients (8.6%) local recurrence was observed. 10-year overall survival was 96.4% and disease-free survival was respectively 68%. The comparison of Polish data to analysis in German population published by Holtzer et al. (Cancer, 2000) was also performed in this study. We conclude that DTC therapy, currently recommended in our country, gives satisfactory results and that clinical outcome and therapeutic methods are similar both in Poland and Germany.
