Kadish staging system
The modified Kadish system:
A: Confined to Nasal Cavity
B: Extends to Paranasal Sinus
C: Local Extension (orbit or cribriform plate)
D: Distant metastases
1) (which added category D to the original Kadish system 2)).
This classification appears to correlate with survival. 3) Alternative systems by Biller et al 4) and Dulguerov and Calcaterra 5) attempt to subdivide the Kadish C classification; however, the more popular modified Kadish staging system is more frequently used.
