Q: Question: Does minimal extrathyroid extension affect the relapse-free survival of patients with papillary thyroid carcinoma measuring 4 cm or less over the age of 45 years?
Answer: These findings suggest that tumors with minimal extension should be classified to have the same T grade as those without such extension, and upstaging of such tumors is therefore not appropriate.
A:
no
