TNM v1.7 changes:

  • Colon and Rectum, Combined T table: When one of Clinical T or Path T is missing, the Combined T table for Colon and Rectum was not handling T4. T4 has been added.
  • General: if Clin and Path T, N, M and Stage Group are all set to 88, then the Derived Combined T, N, M and Stage Group will be set to 88. This happened without error for most schemas, but Prostate was incorrectly returning an error messages.
