Is Tumor Size the Best Predictor of Outcome for Papillary Thyroid Cancer

Background There are many risk classification schemes that determine both treatment and outcome for patients with papillary thyroid cancer. Most of these formulas often utilize tumor size as the key predictor of outcome. Furthermore, there is no clear consensus regarding the treatment of small papillary cancers. Therefore, we reviewed our experience in order to determine which factors best predict outcome for papillary thyroid cancer. In addition, we sought to establish a tumor size threshold beyond which papillary cancers require treatment.
