Abstract

Objective To evaluate the outcomes of patients receiving Y- 90 SIR-Spheres in patients with multiple liver metastases from different tumors. Methods: 29 consecutive patients with multiple liver metastases from colorectal (13), Islet cell tumors (9), carcinoid tumors (4) or non-small cell lung cancer (3) who were treated with Y-90 SIR-Spheres between March, 2003 and February, 2006 were included. Only patients who had follow-up radiological exams at our institution were included. Data regarding Y-90 SIR-Spheres dose, lobe of liver treated, and chemotherapy (CTx) administered were collected. Patients’ outcomes were evaluated based on radiological evidence of change in size and number of liver metastases. Results: The study population included 8 females and 21 males at a mean age of 60y. The mean Y-90 SIR-Spheres dose administered was 39.8 mCi. Both lobes of the liver, the right lobe only or the left lobe only were treated in 26, 2, 1 patients, respectively. Sixteen patients received Y-90 SIR-Spheres after CTx failure, 5 patients as adjuvant therapy after completion of CTx, 7 patients as concurrent therapy and one patient refused repeat CTx. The mean interval between the last CTx and Y-90 SIR-Spheres was 108 days. Four patients (14%) demonstrated radiological improvement and 9 (31%) were stable for a mean interval of 2.8 mo. after Y-90 SIR-Spheres infusion. Sixteen patients (55%) demonstrated continued progress of liver metastases. Conclusion: Y-90 SIR-Spheres therapy is useful in reducing or stabilizing multiple liver metastases from a variety of tumors.
