Biliary Tract Neoplasms
Conditions
Brief summary
The purpose of this study is to assess the safety and efficacy of Gemcitabine/cisplatin combined with Adebrelimab and Mecapegfilgrastim in neoadjuvant treatment of potentially resectable Biliary Tract Neoplasms.
Detailed description
After being informed about the study and potential risks, patients giving written informed consent will undergo a 1-week screening period to determine eligibility for study entry. At week 0, patients who meet the eligibility requirements will be receive Gemcitabine/cisplatin combined with Adebrelimab and Mecapegfilgrastim three weeks a cycle, surgery was performed after 4 cycles.
Interventions
Adebrelimab (1200 mg) every three weeks intravenously; Mecapegfilgrastim (6 mg) every three weeks intravenously; Gemcitabine (1000 mg/m2) every three weeks on days 1 and 8 intravenously; Cisplatin (25 mg/m2) every three weeks on days 1 and 8 intravenously
