Objective: To investigate clinical and laboratory toxicity in patients with unresectable liver metastases, treated with yttrium-90 radioembolization (90Y-RE). Methods: Patients with liver metastases treated with 90Y-RE, between February 1st 2009 and March 31st 2012, were included in this study. Clinical toxicity assessment was based on the reporting in patient’s charts. Laboratory investigations at baseline and during a four-month follow-up were used to assess laboratory toxicity according to the Common Terminology Criteria for Adverse Events version 4.02. The occurrence of grade 3–4 laboratory toxicity was stratified according to treatment strategy (whole liver treatment in one session versus sequential sessions). Response assessment was performed at the level of target lesions, whole liver and overall response in accordance with RECIST 1.1 at 3- and 6 months post-treatment. Median time to progression (TTP) and overall survival were calculated by Kaplan-Meier analysis. Results: A total of 59 patients, with liver metastases from colorectal cancer (n = 30), neuroendocrine tumors (NET) (n = 6) and other primary tumors (n = 23) were included. Clinical toxicity after 90Y-RE treatment was confined to grade 1–2 events, predominantly post-embolization symptoms. No grade 3–4 clinical toxicity was observed, whereas laboratory toxicity grade 3–4 was observed in 38% of patients. Whole liver treatment in one session was not associated with increased laboratory toxicity. Three-months disease control rates for target lesions, whole liver and overall response were 35%, 21% and 19% respectively. Median TTP was 6.2 months for target lesions, 3.3 months for the whole liver and 3.0 months for overall response. Median overall survival was 8.9 months. Conclusion: The risk of severe complications or grade 3–4 clinical toxicity in patients with liver metastases of various primary tumors undergoing 90Y-RE is low. In contrast, laboratory toxicity grade 3–4 can be expected to occur in more than one-third of patients without any clinical signs of radiation induced liver disease. [ABSTRACT FROM AUTHOR] |
