Therapeutic alternatives are particularly limited for patients without actionable driver mutations. Here, we report a case of BRAF V600E wild-type, PD-L1-positive (tumor proportion score of 80%) anaplastic thyroid cancer with residual/relapsed disease following surgery and subsequent progression on multi-targeted tyrosine kinase inhibitor therapy. The patient was thereafter treated with a combination of pembrolizumab, nabpaclitaxel and carboplatin, resulting in a sustained near-complete response lasting over 30 months, accompanied by a manageable safety profile. The favorable response in this case suggests that further evaluation of this triplet regimen could be considered for anaplastic thyroid cancer, though this remains a speculative premise requiring validation. Further studies are also needed to clarify the underlying mechanisms of this combination and to identify predictive biomarkers for patient selection.  \nARTICLE HISTORY  \nReceived 21 September 2025 Revised 8 December 2025 Accepted 18 December 2025  \nKEYWORDS  \nAnaplastic thyroid cancer; pembrolizumab;  \nimmunotherapy;  \nchemotherapy; case report  \nIntroduction  \nAnaplastic thyroid cancer (ATC) is a rare but highly lethal type ofthyroid cancer. While it accounts for only 1–2% of all thyroid cancers, ATC contributes to more than half of thyroid cancer-related deaths. 1 Unlike differentiated thyroid cancer (DTC), which has a standardized treatment approach centered on radioiodine therapy with proven efficacy and well-documented adverse effects,2 ATC is resistant to radioiodine therapy due to the loss of sodium iodide symporter expression. Although there have been some improvements in survival for the last 2 decades, ATC still has a poor prognosis with a median overall survival (OS) less than 12 months.3 Chemotherapeutic drugs including taxanes, doxorubicin and platinum agents have been used in inoperable ATC but they rarely lead to responses and long-term survival.4–6 Approximately one-third of ATCs harbor a BRAF V600E mutation. In this subset of patients, the BRAF/MEK targeted combination therapy of dabrafenib and trametinib has been reported to achieve an objective response rate (ORR) of 56% and a median OS of 14.5 months.7 For patients who progress on BRAF/MEK targeted therapy or those without a BRAF V600E mutation, antiangiogenic agents have shown modest efficacy.8,9 Lenvatinib, for instance, is approved for ATC in Japan based on a phase II clinical trial in which it achieved an ORR of 24% and a median OS of 10.6 months in 17 ATC patients.10 Immunotherapy, particularly immune checkpoint inhibitors (ICIs), is currently undergoing clinical evaluation for ATC. A multicenter phase II study tested the PD-1 inhibitor spartalizumab on 42 ATC patients and showed that a small proportion of patients benefited from ICI monotherapy, with an ORR of 19% and a median OS of 5.9 months. 11  \nCombining chemotherapy with immunotherapy might be able to improve clinical efficacy by synergistically boosting immune response, modifying the immunosuppressive tumor microenvironment (TME), and overcoming resistance, potentially improving patient survival. 12 The NCCN guidelines recommend paclitaxel combined with carboplatin as a first-line regimen for ATC.
