A systematic review on the safety and efficacy of yttrium-90 radioembolization for unresectable, chemorefractory colorectal cancer liver metastases

Abstract

Introduction: The management of unresectable, chemorefractory colorectal cancer liver metastases (CRCLM) is a clinical dilemma. Yttrium-90 (Y90) radioembolization is a potentially safe and effective treatment for patients with CRCLM who have failed conventional chemotherapy regimens. Methods: A systematic review of clinical studies before November 2012 was performed to examine the radiological response, overall survival and progression-free survival of patients who underwent Y90 radioembolization of unresectable CRCLM refractory to systemic therapy. The secondary objectives were to evaluate the safety profile of this treatment and identify prognostic factors for overall survival. Results: Tw..
