So far, differential diagnosis is solved with the help of some markers that are frequently expressed in MTC (TTF1, calcitonin, and CEA). However, some of these markers are not absolutely specific of MTC and may be expressed in other tumors.

Moreover, there are not alternative treatments for low response or aggressive neoplasias. The availability of reliable prognostic markers that would allow the PTC to be identified based on their aggressiveness at the time of diagnosis would derive in an individualized treatment.
