Radioembolization with Yttrium-90 Microspheres for the Treatment of Liver Metastases of Pancreatic Adenocarcinoma: A Multicenter Analysis.
PURPOSE: To retrospectively assess the efficacy and safety of radioembolization with yttrium-90 (
MATERIALS AND METHODS: Thirty-three patients with metastatic pancreatic adenocarcinoma that progressed despite systemic chemotherapy and other treatments directed at primary tumors and metastases were treated with
RESULTS: Imaging results showed partial response in 8 patients (42%), stable disease in 7 (37%), and progressive disease in 4 (21%). Median overall survival times after radioembolization and diagnosis of the primary tumor were 8.1 (95% CI, 4.8-12.5) and 20.8 (95% CI, 14.2-29.0) months, respectively. Radioembolization did not produce major hepatic toxicity, and changes in liver enzyme levels were rarely grade ≥ 3 during the 12-week follow-up. The exceptions were 3 patients with grade 3 increased alkaline phosphatase (week 2) and bilirubin levels (week 4), increased bilirubin level (week 12), and decreased albumin level (week 12), respectively. Most reported complications were grade ≤ 2, with 2 patients showing short-term radioembolization-related grade 3 abdominal distention, abdominal pain, fatigue, or ascites.
CONCLUSIONS: Yttrium-90 radioembolization provided a meaningful survival benefit in patients with liver metastases from pancreatic adenocarcinoma that progressed despite previous therapies. Adverse events and liver toxicity were tolerable and only occasionally severe (grade ≥ 3)
Short-term imaging response after drug-eluting embolic trans-arterial chemoembolization delivered with the Surefire Infusion System<sup>®</sup> for the treatment of hepatocellular carcinoma
<div><p>Purpose</p><p>To review the initial imaging responses after drug-eluting embolic trans-arterial chemoembolization (DEE-TACE) delivered with the Surefire Infusion System <sup>®</sup> for the treatment of hepatocellular carcinoma (HCC).</p><p>Methods</p><p>Single center retrospective evaluation of patients who underwent DEE-TACE for HCC, delivered with SIS. Information was gathered from available medical records. Treatment response rates were assessed using the modified Response Evaluation Criteria in Solid Tumors criteria. Assessment of adverse events was categorized per Common Terminology Criteria for Adverse Events version 4.03.</p><p>Results</p><p>Twenty-two patients with 39 hepatocellular carcinoma lesions were treated with the surefire infusion system. Complete response was demonstrated in 32% of patients and 54% of lesions after a single treatment session. Overall disease response was demonstrated in 91% of patients and 85% of lesions after a single treatment. No grade 3 or higher elevations in liver function tests were demonstrated in the short-term.</p><p>Conclusion</p><p>SIS delivered DEE-TACE leads to a higher than expected initial response in patients with HCC.</p></div
