Comparing the Prognostic Value of the Eighth Edition of the American Joint Committee on Cancer/Tumor Node Metastasis Staging System Between Papillary and Follicular Thyroid Cancer

Abstract

In a European population of patients with DTC, the eighth edition of the AJCC/TNM staging system is a better predictor for both OS and DSS than the previous seventh edition for both PTC and FTC. Furthermore, differences in survival rates between PTC and FTC that were present using the seventh edition disappeared using the eighth edition, implying that this new edition is predicting well, regardless of DTC subtype.
