4 cm in greatest dimension, limited to the thyroid gland. T3: Tumor more than 4 cm
in greatest dimension and limited to the thyroid gland, or tumor of any size with
minimal extrathyroid extension (e.g., extension to sternothyroid muscle or perithyroid
soft tissues). N0: No regional lymph node metastasis. N1a: Metastasis to pretracheal,
paratracheal or prelaryngeal/Delphian lymph nodes (Level VI lymph nodes). N1b: Metastasis
