Classification of 3097 patients from the Japanese Melanoma Study database using the American Joint Committee on Cancer Eighth Edition Cancer Staging System

The American Joint Committee on Cancer (AJCC) released the 8th Edition of its Cancer Staging Manual in 2017[1] and it was first implemented in January 2018. The new edition includes several major changes to TNM categories, prognostic stage groups, and criteria, especially among the Stage 3 subclasses. This latest new staging system was created based on data for 43792 patients who had Stage I through III melanoma at initial diagnosis and had received treatment since 1998. The database included patient data from 10 institutes in the United States, Europe, and Australia; thus, less Asian populations were perhaps underrepresented in their analyses.
