Advanced anaplastic thyroid carcinoma with positive expression of PD-L1 response to immune checkpoint inhibitors: A case report.

ABSTRACT: Anaplastic thyroid carcinoma (ATC) is one rare type of thyroid carcinoma without standard systemic treatment for advanced disease. Recent evidence has demonstrated promising efficacy of immune checkpoint inhibitors, particularly those targeting programmed death-1 (PD-1)/programmed death ligand 1 (PD-L1), in a variety of solid tumors. However, there have been no research of immune checkpoint inhibitors plus chemotherapy in ATC. Here, we present the case of a 37-year-old man with metastatic ATC with positive PD-L1 expression, who achieved long-term remission of 34 months after later-line treatment with zimberelimab (a PD-1 inhibitor) and nab-paclitaxel, followed by single-agent zimberelimab maintenance therapy. After three cycles of the combination treatment, the thyroid lesion and the liver
