Transarterial Chemoembolization (TACE) Plus Bevacizumab for Liver Metastases

An Open-Label Pilot Study to Evaluate Efficacy and Safety of Bevacizumab Via Transarterial Chemoembolization (TACE) in Patients With Liver Metastases

Trans arterial chemoembolization (TACE) has emerged as a treatment option for chemotherapy-refractory diseases in Liver metastases. By delivering chemotherapy agents directly to the tumor site, TACE can maximize local drug concentrations and reduce systemic adverse reactions. Bevacizumab is a monoclonal antibody that functions as an angiogenesis inhibitor. It works by slowing the growth of new blood vessels by inhibiting vascular endothelial growth factor A (VEGF-A). The application of Bevacizumab during TACE has not been reported. In this study, we will evaluate the the overall survival (OS)、efficacy, and safety of the application of Bevacizumab during TACE in patients with Liver Metastases by designing an open, single-arm phase II clinical study.

Intervention / Treatment

Experimental: Bevacizumab Transarterial Chemoembolization; The procedure commences with local disinfection and anesthesia, followed by a percutaneous right femoral artery puncture, performed using a modified Seldinger technique. A 5-F Simmons Ⅰ catheter was introduced through a vascular sheath and positioned in the common hepatic artery with the guidance of digital subtraction angiography to identify the tumor-supplying vessels. A 2.8-F microcatheter catheter was advanced into the vessel supplying the hepatic tumor. In cases of bilobar disease, the initial treatment focus was on the lobe with the greatest tumor burden, with the contralateral lobe addressed in a subsequent TACE session scheduled 4-6 weeks apart. In the standard TACE protocol ( hepaspheres are loaded with Irinotecan at 50 mg for colon metastases and Idarubicin at 10 mg for breast metastases), Bevacizumab 50 mg-loaded hepaspheres was added. The procedure was monitored under fluoroscopy until arterial flow stasis was achieved.

Drug: Bevacizumab; Infusion of Bevacizumab-loaded hepaspher through transarterial chemoembolization.
