Eligibility
Inclusion criteria
Inclusion criteria: 1. Male or female >=18 years of age; 2. Histopathologically confirmed HER2-expressing cholangiocarcinoma met the following criteria: HER2-expressing patients were defined as either HER2 + by immunohistochemical staining (IHC) and negative by fluorescence in situ hybridization (FISH), or HER21 + by IHC and ERBB2 amplification by NGS. Tumor stage: Recurrent or metastatic cholangiocarcinoma; Patients with local recurrence need to be confirmed by the investigator that radical surgical resection is not possible. 3. The ECOG score is 0 to 1; 4. No previous treatment with anti-HER2 drugs; 5. At the recurrence/metastasis stage, the patient did not receive any systematic antitumor therapy; 6. Patients with disease recurrence > 6 months after radical surgery; Patients who received adjuvant therapy (chemotherapy and/or radiotherapy) after surgery should be > 6 months after completion of adjuvant therapy; 7. The presence of at least one measurable lesion according to RECIST version 1.1; Lesions located within the field of previous radiotherapy may be considered measurable if progression is demonstrated; 8. Functional level of major organs must be required (no blood transfusion within 2 weeks prior to screening, no use of leukocytotropic or platelet-enhancing drugs); 9. Expected survival >=3 months; 10. Volunteer to participate in this study, sign informed consent, have good compliance and willing to cooperate with follow-up;
