In this issue, two interesting studies are published by Ito et al. in an attempt to subclassify thyroid cancer T and N staging. The AJCC 8th edition defines T staging by size and by extent of extrathyroidal extension (intraoperative findings) and N staging by compartment involvement (N1a—central, and N1b—lateral) [1]. The authors used a large cohort of thyroid cancer patients treated at a tertiary well-known center in Japan to further evaluate subgroups of patients that warrant re-staging. With… 


Prognostic Value of Extranodal Tumor Extension in Papillary Thyroid Carcinoma: Proposal for Upstaging of Cases with Extranodal Tumor Extension
The prognostic significance of extranodal tumor extension (LNEx) in PTC is investigated and LNEx-positive patients younger than 55 years in Stage I and those aged 55 or older in Stage II are re-staged to II and III, respectively.
Subclassification of Tumor Extension and Nodal Metastasis in Papillary Thyroid Cancer to Improve Prognostic Accuracy of the Eighth Edition of the Tumor–Node–Metastasis Classification
Subdivision of clinical tumor extension and node metastasis further improves the TNM-8th for PTC and identifies poor risk patients more accurately.
