Aim Of The Study: The aim of the project was to investigate regional differences in thyroid stimulating hormone (TSH), and free thyroxine (fT4) concentrations and iodine status in comparable German and European cohort studies.
Methods: Sex- and age-stratified TSH, fT4, and urine iodine concentrations of thyroid-healthy participants (age group 45-75 years) of the HNR (Heinz Nixdorf Recall) Study in the Ruhr region of Germany, the southern German KORA (Cooperative Health Research in the Augsburg Region) and northeastern German SHIP (Study of Health in Pomerania) studies, as well as the Norwegian HUNT (Nord-Trøndelag Health) study (age group 40-79 years), the English EPIC (European Prospective Investigation of Cancer)-Norfolk study, and the Dutch Rotterdam study were compared. The TSH reference range for the HNR study population was calculated and compared to the KORA and SHIP studies.
Introduction: Primary squamous cell carcinoma (PSCC) of the thyroid is an exceptionally rare malignancy accounting for <1% of all primary thyroid cancers. Therapy is multimodal including surgery, radiotherapy, and chemotherapy but with no consensus for management and therapy. Here, we describe a case of a male patient who presented with a BRAF V600E-mutated PSCC of the thyroid gland showing response to combined dabrafenib and trametinib therapy over a period of >12 months.

Only recently, toxicity in long-time TKI usage was analysed. However, little is known about the impact of TKI discontinuation on MTC disease course after longer-term therapy.
