Solid Tumor Rules: January 2019 Update

The 2018 Solid Tumor Rules were published June 2018 without prior beta testing. As a result, registrars using the rules identified issues. Based on questions and suggestions received since release of the 2018 rules, we have added clarifications, additional notes and examples, and in a few sites, rules. A comprehensive change log has also been posted for reference. These revisions do not require you to review and or re-abstract 2018 cases.


IMPORTANT: We have added clarifications and specific criteria that must be met to code a histology identified only by ambiguous terminology. This information is in the Histology rules section of each revised site.


The updated rules published January 2019 apply to the following sites only:


• Breast

• Colon/Rectum

• Head & Neck

• Lung

• Kidney

• Malignant CNS

• Non-malignant CNS

• Urinary


The 2018 Solid Tumor are now available in a consolidated PDF file and can be accessed at the following site: https://seer.cancer.gov/tools/solidtumor/


Revision status for remaining 2007 Multiple Primary and Histology site rules:


We are currently working on revisions to the remaining two MP/H site groups. Release date of the final sites has not yet been determined. Based on the recent WHO 4th Ed Tumors of Skin, we do not expect major changes to the cutaneous melanoma rules.


Other sites:

We have identified the need to separate select sites into individual modules. These site-specific rules may be individual sections within the Other sites rules, or free-standing module. Revisions will be based on the following 4th Ed WHO Blue Books:

Tumors of Endocrine Organs

Female Reproductive Organs

Tumors of Soft Tissue & Bone

Tumors of Male Genital Organs (included in the Tumors of Urinary System BB)



The Solid Tumor module will be added to SEER*Educate soon. We will notify the registrar community when the module is available. Additional educational modules will be developed and available through NCRA free of charge.
