简要总结
Phase I/II trial to study the effectiveness of combining yttrium Y 90 ibritumomab tiuxetan with rituximab in treating patients who have localized or recurrent lymphoproliferative disorder after an organ transplant. Monoclonal antibodies such as yttrium Y 90 ibritumomab tiuxetan and rituximab can locate cancer cells and either kill them or deliver radioactive cancer-killing substances to them without harming normal cells
详细描述
OBJECTIVES:
I. Determine the safety and tolerability of yttrium Y 90 ibritumomab tiuxetan (IDEC-Y2B8) in patients with post-transplant lymphoproliferative disorder.
II. Determine the safety and toxicity profile of IDEC-Y2B8 and rituximab in these patients.
III. Correlate the Epstein-Barr virus viral load with response and relapse in patients treated with this regimen.
OUTLINE: This is a multicenter, dose-escalation study of yttrium Y 90 ibritumomab tiuxetan (IDEC-Y2B8).
