Derived Staging

Derived staging information is given so that the user may compare these codes to their manual codes in the earlier exercises.

Stage Code

  • T: cT4
  • N: pN2
  • M: cM0
  • AJCC Stage: IIIC
  • Summary Stage: 4, regional by both direct extension and regional lymph nodes

Note: Derived Stage is different from directly coded Stage because CS allows use of CT information to be included in lymph node assessment.
