Papillary and follicular variant of papillary carcinoma of the thyroid: Initial presentation and response to therapy

FVPTC presented with larger original tumor size and higher tumor stage but a lower local invasion rate and recurrence rate than patients with PTC despite similar therapies. These data suggest that FVPTC and PTC carry similar prognoses in early stages and that FVPTC may have a reduced predilection for local invasion. Although further studies with longer follow-up are required, these results do not suggest that FVPTC warrants more aggressive therapy than PTC.
