Is 131I thyroid remnant ablation recommended for papillary papillary cancer?

Recently, however, 131I ablation is not uniformly recommended for cancers smaller than 10 mm, and its use is debated for papillary tumours with diameter between 10 and 20 mm. Indeed, the decision about subsequent 131I thyroid remnant ablation is recommended as “individualized and selective”.

What is iodine-131 for thyroid ablation?

The purpose of Iodine-131 for thyroid ablation is to destroy all functioning thyroid tissue. It has been shown that the use of thyroid hormones after surgery decreases the recurrence rate of cancer — a rate that is further decreased when radioiodine is used postsurgically.

What is the role of radioiodine (131I) in the treatment of thyroid cancer?

In DTC patients, total thyroidectomy has been for many decades routinely followed by the administration of radioiodine (131I) activity to destroy remnant thyroid tissue. Several reasons are in favour to routine ablation of postoperative thyroid remnants.
