WebIf cancer has spread to other neck lymph nodes, a modified radical neck dissection (a more extensive removal of lymph nodes from the neck) is often done. Radioactive iodine (RAI) treatment is sometimes used after thyroidectomy for early stage cancers (T1 or T2), but the cure rate with surgery alone is excellent. WebMutation of NRAS can be found in follicular carcinomas, follicular-variant papillary thyroid carcinomas, and follicular adenomas. In this case, the surgeon’s gross assessment of the thyroid nodule contributed to the decision-making process by reducing suspicion of a classic papillary carcinoma or a widely invasive follicular carcinoma.
