Impact of Chemotherapy Educational Videos for Patients with Acute Myeloid Leukemia.

Patient education in acute myeloid leukemia (AML) has become increasingly complex with the introduction of new treatments and chemotherapy regimens. Video education presents an opportunity to supplement traditional patient education and address some of the gaps associated with standard methods. This single-center study sought to assess the potential impact of supplemental video education on patients receiving induction chemotherapy for AML. Participants were consented to be randomized to receive their education with or without a supplemental video designed for their treatment regimen. We then provided a survey to each participant to assess knowledge retention, anxiety, and overall satisfaction with their care. Patients that received video education were found to have significantly improved knowledge retention compared to those that did not. There were no differences detected in anxiety or patient satisfaction. Video education appears to be an effective supplemental method for patient education in AML. Limitations include the single-center nature of the study at an urban academic medical center with a relatively well-educated, primarily Caucasian, younger population. Future research is warranted to assess the video in a diverse set of languages and to explore its broader benefits.

Tumor lysis syndrome in patients with acute myeloid leukemia treated with venetoclax and hypomethylating agents with or without dose ramp-up.

Venetoclax with hypomethylating agents (HMAs) is an important treatment for patients with acute myeloid leukemia (AML) who cannot tolerate intensive chemotherapy. However, there is limited data on the safety of venetoclax without a dose ramp-up in patients with AML. A retrospective cohort analysis of patients with AML treated with HMA/venetoclax (HMA/Ven) with or without a dose ramp-up, or HMA alone from 6/30/2014-8/22/2022 was conducted. The primary endpoint was the incidence of laboratory and/or clinical tumor lysis syndrome (TLS) by day 10. Of 225 patients, 111 patients received HMA alone or HMA/Ven with a dose ramp-up and 114 received HMA/Ven with no dose ramp-up. The incidence of TLS was similar between the control and no dose ramp-up groups, with rates of 5.4% and 5.3% respectively (p = 0.962). TLS incidence was comparable in patients with and without a dose ramp-up, suggesting that a dose ramp-up may not be mandatory in patients with AML.

Gilteritinib clinical activity in relapsed/refractory FLT3 mutated acute myeloid leukemia previously treated with FLT3 inhibitors.

Gilteritinib is approved for the treatment of relapsed/refractory (R/R) acute myeloid leukemia (AML) with an FLT3-mutation (FLT3mut+ ). However, the gilteritinib phase 3 ADMIRAL study (Perl et al NEJM 2019) was conducted prior to widespread adoption of either midostaurin as a component of standard intensive induction and consolidation or posttransplant FLT3 inhibitor maintenance. We performed a retrospective analysis using data from 11 US centers and where we identified 113 patients who received gilteritinib alone or as combination therapy for the treatment of R/R FLT3mut+ AML. The composite complete remission (CR) rate (CRc, defined as CR + CRi + CR with incomplete platelet recovery [CRp]) was 48.7% (n = 55). The CRc rate after treatment with gilteritinib in patients who were treated with only prior 7+3 and midostaurin with or without consolidation was 58% with a median survival of 7.8 months. Survival was longest in patients who obtained a CR, particularly a cMRD (clinical minimal or measurable residual disease) negative response; this remained significant after censoring at the time of stem cell transplant. The mitogen-activated protein kinase pathway activating mutations that are known for gilteritinib resistance (NRAS, KRAS, and PTPN11) had lower CRc (35% vs. 60.5%) and lower median overall survival than patients' whose leukemia did not express these mutations (4.9 months vs. 7.8 months) (HR 2.4; 95% CI 1. 5.4) p value <.01.
