Survival strongly correlates with stage of disease at diagnosis, illustrating the need for early diagnosis. Calcitonin is a well-established tumour marker for MTC, but its use in the screening phase is limited by a high rate of fal...

Studies evaluating this 8th edition so far only comprised patients with papillary thyroid cancer (PTC) or made no distinction between PTC and follicular thyroid cancer (FTC). Therefore, we evaluated the prognostic value of the AJCC/TNM 8th edition in a European population with DTC, and subsequently distinguished PTC and FTC pa...
