Cognition in patients treated with targeted therapy for chronic myeloid leukemia: a controlled comparison.

This controlled comparison study evaluated objective and subjective cognitive function and their relationships with patient-reported symptoms (depression, fatigue, insomnia) in patients receiving tyrosine kinase inhibitors (TKIs) for chronic myeloid leukemia (CML) and non-cancer controls. Patients with CML in chronic phase treated with the same oral TKI for ≥6 months (n = 90) and non-cancer controls (n = 87) completed a neurocognitive battery and self-report measures. Patients demonstrated worse overall neuropsychological performance (p = .05) and verbal memory (p = .02) compared to controls. Patients were not more likely to meet criteria for impaired cognitive performance compared to controls (ps>.26). Patients reported worse subjective global and domain-specific cognitive complaints and less satisfaction with cognitive function compared to controls (ps < .05). Patients also reported greater fatigue and insomnia symptoms (ps < .001). In both groups, greater fatigue, insomnia, and depressive symptoms were associated with worse subjective cognition (ps < .01). Longitudinal studies are needed to examine changes in cognitive function in patients before and during TKI treatment.

Efficacy of bendamustine and rituximab as first salvage treatment in chronic lymphocytic leukemia and indirect comparison with ibrutinib: a GIMEMA, ERIC and UK CLL FORUM study.

We performed an observational study on the efficacy of ben-damustine and rituximab (BR) as first salvage regimen in chronic lymphocytic leukemia (CLL). In an intention-to-treat analysis including 237 patients, the median progression-free survival (PFS) was 25 months. The presence of del(17p), unmutated IGHV and advanced stage were associated with a shorter PFS at multivariate analysis. The median time-to-next treatment was 31.3 months. Front-line treatment with a chemoimmunotherapy regimen was the only predictive factor for a shorter time to next treatment at multivariate analysis. The median overall survival (OS) was 74.5 months. Advanced disease stage (i.e. Rai stage III-IV or Binet stage C) and resistant disease were the only parameters significantly associated with a shorter OS. Grade 3-5 infections were recorded in 6.3% of patients. A matched-adjusted indirect comparison with ibrutinib given second-line within Named Patient Programs in the United Kingdom and in Italy was carried out with OS as objective end point. When restricting the analysis to patients with intact 17p who had received chemoimmunotherapy in first line, there was no difference in OS between patients treated with ibrutinib (63% alive at 36 months) and patients treated with BR (74.4% alive at 36 months). BR is an efficacious first salvage regimen in CLL in a real-life population, including the elderly and unfit patients. BR and ibrutinib may be equally effective in terms of OS when used as first salvage treatment in patients without 17p deletion.
