Purpose: Tall cell (TCV) and diffuse sclerosing (DSV) variants are aggressive variants of papillary thyroid cancer (PTC). We compared the risk of recurrent/persistent disease in patients with TCV, DSV and classical PTC (cPTC) and evaluated the prognostic accuracy of initial vs. ongoing risk stratification. Methods: A consecutive series of DSV (n = 54), TCV (n = 72) and cPTC (n = 184) patients was retrospectively analyzed. TCV and DSV patients were first risk stratified for recurrent/persistent disease without considering the histotype as a risk factor and subsequently, 6â24 months after initial treatment, re-classified on the basis of the response to therapy (ongoing risk stratification). Results: Extrathyroidal extension was more frequent in DSV than in TCV and cPTC patients (pÂ

We compared the risk of recurrent/persistent disease in patients with TCV, DSV and classical PTC (cPTC) and evaluated the prognostic accuracy of initial vs. ongoing risk stratification. Methods: A consecutive series of DSV (n = 54), TCV (n = 72) and cPTC (n = 184) patients was retrospectively analyzed. TCV and DSV patients were first risk stratified for recurrent/persistent disease without considering the histotype as a risk factor and subsequently, 6â24 months after initial treatment, re-classified on the basis of the response to therapy (ongoing risk stratification). Results: Extrathyroidal extension was more frequent in DSV than in TCV and cPTC patients (pÂI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
