Usage

In AJCC terminology, examples of N categories include ‘ycN0’, for post-therapy clinical stagin indicating no evidence of lymph node involvement, and ‘pN1’, indicating regional lymph node involvement to a small extent, with specific thresholds for the lymph node groups and number of lymph nodes involved. Other N categories refer to increasing lymph node involvement. Please note allowable N categories may vary between clinical, pathologic, and other classifications, and the N category prefix must align with Observation.code. The full set of allowable clinical, pathologic, and other (recurrence/retreatment/autopsy) N categories, along with current descriptions, can be accessed through the AJCC Staging Manual and any applicable updates and corrections, as well as the AJCC API.

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
