Notes

C739 Thyroid gland

Note 1: This schema is based on the UICC chapter Thyroid, pages 58-62.

Note 2: The determination of TNM stage group from T, N, and M for thyroid depends on histologic type, grade, and age. The Histologies, Grade, Stage table shows the selection of the TNM Stage table based on histology and grade. For papillary and follicular carcinomas, age is also needed for the selection; if age at diagnosis is unknown, TNM stage will be derived as unknown for these histologies.

Note 3: In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the Thyroid Gland chapter on page 276 of the SS2000 on-line manual.
