Decreasing the dose of radioiodine for remnant ablation does not increase structural recurrence rates in papillary thyroid carcinoma.

Background: Our aim was to compare the rate of structural recurrence between patients who had lesser doses of radioactive iodine (RAI) and those who had traditional greater doses for remnant ablation after total thyroidectomy for papillary thyroid carcinoma (PTC).

Methods: A retrospective cohort study of patients who had undergone thyroidectomy and RAI for PTC was undertaken. We divided the cohort into those who had < or =3 GBq (75 mCi) RAI (group A) and those who had >3 GBq (75 mCi) RAI (group B).

Patterns of structural recurrence in papillary thyroid cancer.

Background: Papillary thyroid carcinoma (PTC) is uncommonly associated with tumor-related mortality, although local recurrence can be a frequent and difficult problem. This study was conducted to clarify the pattern of structural locoregional recurrence in PTC.

Material And Method: A retrospective cohort study of patients undergoing surgical intervention for PTC was undertaken.
