TACE Associated to Systemic Bevacizumab for the Treatment of Refractory Liver Metastases From Colorectal Cancer

Transarterial chemoembolization (TACE) is an effective, minimally invasive therapy that is widely used for unresectable colorectal cancer liver metastases (CRC-LM) treatment. Chemoembolization, however, induces a hypoxic micro-environment, which increases neo-angiogenesis, and may promote early progression. For this reason, efficacy may be improved by associating TACE with an angiogenesis inhibitor, such as bevacizumab.
The use of FOLFIRI associate to Bevacizumab is part of clinical practice and is commonly used for the therapy of patients with CRC-LM both wild type and mutant.
This case-control observational study aim to compare patients treated with TACE using Irinotecan-loaded embolics followed by systemic Bevacizumab versus patients treated with FILFIRI+ Bevacizumab
