The guidance synthesizes clinical, radiographic, and molecular features to support multimodal treatment algorithms based on risk–benefit assessments. Because evidence remains scarce for this rare but highly aggressive condition, the consensus is designed to provide practical direction for endocrinology, oncology, pathology, radiation oncology, and surgical teams in optimizing patient management.

Here, we provide consensus recommendations reached by a multidisciplinary group of endocrinologists, medical oncologists, pathologists, radiation oncology specialists, a surgeon and a medication reimbursement specialist, addressing more challenging forms of this malignancy, focused on radioactive iodine (RAI) -resistant or -refractory differentiated thyroid carcinoma (RAIRTC) . In this document we highlight clinical, radiographic, and molecular features providing the basis for these management plans. We distinguish differentiated thyroid cancers associated with more aggressive behavior from thyroid cancers manifesting as poorly differentiated and/or anaplastic carcinomas. Treatment algorithms based on risk-benefit assessments of different multimodal therapy approaches are also discussed.
