简要总结
Phase II, multi-centric, open-label, study.
Disseminated diffuse large B-cell lymphoma in patients older than 60: evaluation of fractionated radio-immunotherapy with 90Y-DOTA-hLL2 as a consolidation therapy after first line of chemotherapy.
详细描述
Initial treatment: 6 courses of CHOP-R 14 with evaluation of response before C4 (observation of no change or progression at this time will get the patient off study).
Consolidation : fractionated RIT (8 weeks after the end of R-CHOP: 2 injections of 15 mCi/m2 of 90Y-DOTA-hLL2 and hLL2 at day 1 and day 8).
