Chemoembolization Alone or Associated With Bevacizumab for Therapy of Colorectal Cancer Metastases: Preliminary Results of a Randomized Study.

AIM: to assess efficacy and safety of chemoembolization alone (TACE) and followed by bevacizumab (TACE-B) in patients with colorectal liver metastases (CRC-LM) (NCT03732235). PATIENTS AND METHODS: The study included 30 consecutive patients with CRC-LM. They were informed about the types of treatment available: TACE with irinotecan loaded into polythylene glycol embolics alone or followed by bevacizumab therapy. Each patient underwent self-randomization and 17 chose TACE, whereas 13 chose TACE-B.
RESULTS: Tumor response at 3 months was complete response in one (6%) and four (31%) patients, and partial response in two (13%) and six (46%) patients, after TACE and TACE-B, respectively. No complications were observed during TACE. Most TACE-related adverse events were correlated with post-embolic syndrome.
CONCLUSION: The preliminary results of the study showed that the TACE-B is feasible and tolerable. This study will be continued in order accrue a larger number of patients and longer follow-up. Copyright
