Tang J, et al. - In this retrospective analysis, researchers used data from the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) program to investigate if radioactive iodine (RAI) therapy could improve the survival rates of papillary thyroid cancer (PTC) patients. They used multivariate Cox proportional hazard regressions to obtain disease-specific survival (DSS). Based on the findings, RAI ablation was recommended for patients with tumor < 2 cm and distant metastasis or patients with tumor > 2 cm and one of the following risk factors: gross extrathyroidal extension, age >45 years, or lymph node and distant metastases.
