PURPOSE
To evaluate the efficacy and tolerability of chemotherapy, a geriatric assessment is recommended in elderly patients with cancer. We aimed to characterize and compare patients with aggressive lymphoma by objective response and survival status based on pre-treatment cancer-specific geriatric (C-SGA) and quality of life (QoL) assessments.

METHODS
Patients not eligible for anthracycline-based first-line therapy or intensive salvage regimens completed C-SGA and QoL assessment before and after a rituximab-bendamustine-lenalidomide (R-BL) treatment in a phase II clinical trial. Clinical outcomes were compared based on pre-treatment individual and summary C-SGA measures, their cutoff-based subcategories and QoL indicators, using Wilcoxon rank sum or chi-square tests.

RESULTS
A total of 57 patients (41 included in the clinical trial) completed a C-SGA. Participants with pre-treatment impaired functional status (Vulnerable Elders Survey-13 score ≥3) were more likely to experience worse outcomes: a higher proportion were non-responders, died before the median follow-up of 31.6 months (interquartile range (IQR) 27.9-37.9) or died during treatment. Non-responders were patients categorized as having possible depression (Geriatric Depression Scale-5 score ≥2) and with worse QoL scores for functional performance. Patients with worse C-SGA summary scores and with greater tiredness were more likely to die during treatment.

CONCLUSION
A pre-treatment impaired functional status is an important factor with respect to clinical outcomes in patients receiving an R-BL regimen. Individual geriatric and related QoL domains showed similar associations with clinical outcomes. Whether interventions targeting specific geriatric dimensions also translate in better symptom- or domain-specific QoL warrants further research.
