Undetectable Thyroglobulin Levels in Poorly Differentiated Thyroid Carcinoma Patients Free of Macroscopic Disease After Initial Treatment: Are They Useful?
Postoperative thyroglobulin levels in subset of patients with PDTC appear to have predictive value for recurrence. Patients with undetectable Tg have a low rate of recurrence.
It is interesting and necessary to explore the use of econometric tools in cost and cost effectiveness analysis to investigate the effect of a technology in everyday practice and to take into account patient and disease characteristics and uncertainty. Further research is however necessary to investigate how we can fully correct for selection bias when using observational data.
