There are 12 new SSDIs that are being proposed for implementation in 2021.
·
Breast and Colon: Treatment Effect (Primary Tumor)
·
Breast: Treatment Effect (Lymph Nodes)
·
Colon and Rectum: NRAS Mutational Analysis
·
Colon and Rectum: BRAF Mutational Analysis
·
Lung: EGRF Mutational Analysis
·
Lung: ALK Rearrangement by Molecular Methods
·
Pancreas: CA 19-9 Pre Tx-Lab Value
·
Neuroendocrine Tumors: Ki-67 (Ampulla of Vater, Appendix, Colon and Rectum, Pancreas, Small Intestine, Stomach)
·
Corpus Carcinoma and Carcinosarcoma: ER and PR
·
Esophagus and Stomach: HER2 Overall Summary
Each of these SSDIs has clinical significance for their cancers. The field testing will provide information to the NAACCR SSDI workgroup for
- Clarification of codes and coding instructions
- Needed revisions and/or modifications
- How often the information is available
- Feasibility of implementing the new SSDI
In addition to new SSDIs being tested, there will also be testing on changes to how the registry collects Neoadjuvant therapy. These changes will include a new data item that asks, "was neoadjuvant therapy given." This new data item will provide clear instructions on what is neoadjuvant therapy, along with codes determining if patient had neoadjuvant therapy or not.
