Up to 80% of biliary tract cancer (BTC) patients relapse within 3 years after surgery and the efficacy of second‐line treatment remains dismal for patients who progressed on gemcitabine and cisplatin chemotherapy. Median overall survival of patients with palliative chemotherapy is less than 1 year. The feasibility and safety of targeted therapies plus immunotherapies remain scanty currently, and patients with recurrent or advanced BTCs often experience a rapid decline in Eastern Cooperative Oncology Group (ECOG) performance status. This case report is the first report suggesting a 17-month progression-free survival (PFS), partial response, and another 11-month PFS after progressive disease of anlotinib plus toripalimab in advanced BTC with high ECOG performance status. We report a 67-year-old Chinese male with BTC. He was observed with progressive disease after surgical resection, adjuvant chemotherapy, palliative chemotherapy, and diagnosed with American Joint Committee on Cancer clinical stage IV (cT3N0M1) extrahepatic BTC. The patient experienced a rapid decline in performance status, and he received oral anlotinib and toripalimab with informed consent. MRI scans showed partial response on 22 June 2022. PET-CT showed that tumor activity has been inhibited on 8 March 2023. He achieved 17 months of PFS. Although the patient developed solitary lung metastasis, he had a continuous survival benefit from treatment of anlotinib plus toripalimab after lung radiotherapy. Until the writing of the case draft, he had achieved another 11 months of PFS. The present case suggests that anlotinib plus toripalimab might be a potential effective treatment for advanced BTCs patients with high ECOG performance status.
