TNM v2.0 changes:
Derived SEER Combined Tand
Derived SEER Combined N: the logic tables for calculating
Combined Nwere updated so that if
RX Summ Surg/
Rad Seq or
RX Summ Systemic/
Sur Seq = 2, 4 or 7, the patient will be considered to have received neoadjuvant therapy. 7 (Surgery both before and after therapy) has been added to the list of codes considered to be neoadjuvant therapy.
- Field Validation tables: due to the change from fixed column formatting to XML, the validation tables for all fields were reviewed and any leading and trailing spaces were removed.
TNM v2.0 Review and Conversion:
After TNM 2.0 has been deployed, reprocess the cases diagnosed in 2016-2017
Recalculate the Derived SEER Combined fields
No changes are expected in the
Derived SEER Clin Stage Group,
Derived SEER Path Stage Group,
Derived SEER Combined Mor any of the Derived SEER Combined Source fields. (This can always be applied. Calculation tables were updated. No review necessary.)
