BACKGROUND: The mean age of patients included in clinical trials does not reflect the current clinical practice for patients with B-cell non-Hodgkin lymphoma (B-NHL). We compared our outcomes for patients with B-NHL aged < 65 and > 65 years who were treated with 90-yttrium-ibritumomab tiuxetan therapy ((90)Y-IT).
PATIENTS AND METHODS: A total of 108 patients who had received (90)Y-IT according to the hospital protocol (ISCRTN36210045) were eligible. A quality of life (QoL) assessment using the Medical Outcomes Study short form 36-item survey was performed for patients aged > 65 years.
RESULTS: Of the 108 patients, 43 were aged > 65 years (mean age, 73.4 years; men 46.15%); 37 had follicular NHL (86.0%). Also, 27 patients had previously undergone < 2 therapy regimens (62.8%). The mean follow-up period was 45.2 months. The mean progression-free survival (PFS) period was 71.3 months, and the mean overall survival was 78.2 months. The median values were not reached. The overall response rate was 90.5%, and a complete response was observed in 36 of the 43 patients aged > 65 years (85.7%). Neutropenia (43.3%) and thrombocytopenia (45.2%) were the most frequent grade 3 and 4 toxicities. Five patients required a red blood cell transfusion and 11, a platelet transfusion. Five patients aged > 65 years (11.6%) developed a second tumor. These outcomes were similar to those for the younger patients. The QoL assessment showed scores similar to those of general population for general health and social functioning.
CONCLUSION: This is the largest cohort of NHL treated with RIT in a single institution in Spain. We observed a high response rate and prolonged PFS in patients with B-NHL, independent of patient age. Thus, consolidation RIT offers better outcomes with manageable toxicity.
