Estimates of stage-specific survival are altered by changes in the 2002 American Joint Committee on Cancer staging system for melanoma
Estimates of stage-specific survival were altered substantially by the changes made in the 2002 AJCC staging system for melanoma, particularly for Stage II. Stage subgroups that were added in the 2002 system resulted in a large diversity of risk within Stage III. This must be taken into account to stratify patients properly for clinical trials. The increased complexity of the 2002 system did not improve its predictive ability over the simpler 1997 system, highlighting the importance of developing individualized risk-prediction models.
