This view displays the TNM formula.Please select appropriate value from the list for T/N/M/G variables. The result will be displayed, based on your selection of variables.

Neoadjuvant Pathological T (yT)

ypT Category ypT Criteria
ypTX Primary tumor cannot be assessed
ypT0 No evidence of primary tumor
ypT1 Tumor less than or equal to 2 cm in greatest dimension limited to the thyroid
ypT1a Tumor less than or equal to 1 cm in greatest dimension limited to the thyroid
ypT1b Tumor greater than 1 cm but less than or equal to 2 cm in greatest dimension limited to the thyroid
ypT2 Tumor greater than 2 cm but less than or equal to 4 cm in greatest dimension limited to the thyroid
ypT3 Tumor greater than 4 cm limited to the thyroid, or gross extrathyroidal extension invading only strap muscles
ypT3a Tumor greater than 4 cm limited to the thyroid
ypT3b Gross extrathyroidal extension invading only strap muscles (sternohyoid, sternothyroid, thyrohyoid, or omohyoid muscles) from a tumor of any size
ypT4 Includes gross extrathyroidal extension beyond the strap muscles
ypT4a Gross extrathyroidal extension invading subcutaneous soft tissues, larynx, trachea, esophagus, or recurrent laryngeal nerve from a tumor of any size
ypT4b Gross extrathyroidal extension invading prevertebral fascia or encasing the carotid artery or mediastinal vessels from a tumor of any size
Neoadjuvant Pathological N (pY)
ypN Category ypN Criteria
ypNX Regional lymph nodes cannot be assessed
ypN0 No evidence of locoregional lymph node metastasis
ypN0a One or more cytologically or histologically confirmed benign lymph nodes
ypN1 Metastasis to regional nodes
ypN1a Metastasis to level VI or VII (pretracheal, paratracheal, or prelaryngeal/Delphian, or upper mediastinal) lymph nodes. This can be unilateral or bilateral disease.
ypN1b Metastasis to unilateral, bilateral, or contralateral lateral neck lymph nodes (levels I, II, III, IV, or V) or retropharyngeal lymph nodes

Definition of Distant Metastasis (M)- Neoadjuvant Pathological M (pY)

ypM Category ypM Criteria
cM0 No distant metastasis
cM1 Distant metastasis
pM1 Microscopic evidence of distant metastasis
