Description:
This data item records the grade of a solid primary tumor that has been resected following neoadjuvant therapy. If AJCC staging is being assigned, the tumor must have met the surgical resection requirements in the AJCC manual.
Record the highest grade documented from the surgical treatment resection specimen of the primary site following neoadjuvant therapy.
For cases diagnosed January 1, 2018, and later, this data item, along with Grade Clinical and Grade Pathological, replaces NAACCR Data Item Grade [440] as well as SSF’s for cancer sites with alternative grading systems (e.g., breast [Bloom-Richardson], prostate [Gleason]).
Rationale:
Grade is a measure of the aggressiveness of the tumor. Grade and cell type are important prognostic indicators for many cancers. For some sites, grade is required to assign the post-neoadjuvant stage group.
For those cases that are eligible AJCC staging, the recommended grading system is specified in the AJCC Chapter. The AJCC Chapter-specific grading systems (codes 1-5) take priority over the generic grade definitions (codes A-E, L, H, 9). For those cases that are not eligible for AJCC staging, if the recommended grading system is not documented, the generic grade definitions would apply.
