age, tumor size, local invasion and distant metastasis are independent predictive variables …

Background Numerous prognostic factors have been studied for survival in patients with
papillary thyroid carcinoma (PTC), although there are few multivariate studies that include …

Hypothesis The prognosis of papillary thyroid carcinoma has been stratified into low-and
high-risk groups. Patients in the high-risk group can be substratified on the basis of …

We have analyzed data on a group of 269 patients with papillary thyroid carcinoma followed
on average for 12 years to determine (1) if a prognostic classification scheme can be used to …

(PTC) currently available in the literature. Background: Various staging systems or risk group …

From a multivariate analysis of more than 20,600 patient-years' experience with papillary
thyroid carcinoma (PTC), we devised a prognostic scoring system based on patient age …
