Article Synopsis
  • The study compared the outcomes of AML patients treated with a combination of hypomethylating agents and venetoclax, focusing on various levels of remission defined by ELN 2022.
  • Among 120 patients, the best responses were complete remission (43.3%), partial remission (18.3%), incomplete remission (25.8%), and morphologic leukemia-free state (12.5%).
  • The results indicated that those with MLFS had a history of prior myeloid malignancies and had worse overall survival and relapse-free survival compared to those who achieved better response categories.

Article Synopsis
  • A retrospective study evaluated the impact of next-generation sequencing (NGS) mutations on outcomes in patients with secondary acute myeloid leukemia (sAML) who were treated with CPX-351 from 2017 to 2021.
  • Common mutations included DNMT3A, SRSF2, RUNX1, TET2, ASXL1, and BCOR, with a median overall survival (mOS) of 47 months for the cohort.
  • While patients who cleared their mutations experienced longer mOS and relapse-free survival (RFS) numerically, the differences were not statistically significant, and alloSCT improved RFS regardless of mutational status.

Leukoencephalopathy in the setting of multiple myeloma (MM) is a rare demyelinating condition, with few reported cases in literature. Daratumumab is a CD38 targeted monoclonal antibody that has been widely used for the management of MM. In the absence of central nervous system (CNS) disease, many medication-induced leukoencephalopathy cases reported with MM, including daratumumab-induced, are associated with progressive multifocal leukoencephalopathy (PML) and John Cunningham (JC) virus.

Diffuse large B-cell lymphoma (DLBCL) is the most common form of aggressive non-Hodgkin lymphoma. Approximately 40% of patients with DLBCL will experience disease relapse or will be refractory to first line chemoimmunotherapy, necessitating second-line salvage therapy. This has historically consisted of platinum-based chemotherapy regimens followed by autologous hematopoietic stem cell transplantation with curative intent for transplant-eligible patients or palliative chemotherapy for transplant-ineligible patients.

Introduction: Dose-adjusted (DA-) EPOCH (etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin) is a front-line treatment option for aggressive B-cell lymphomas. Due to regimen complexity, inpatient administration of DA-EPOCH has been historically required. Moffitt Cancer Center (MCC) developed an Inpatient/Outpatient (IPOP) program to facilitate administration of complicated regimens in the outpatient setting.

Historically, patients with acute myeloid leukemia received intensive chemotherapy requiring hospitalization, which can diminish quality of life and increase healthcare costs. The introduction of new therapies facilitated a shift toward outpatient therapy, which requires coordination of a multidisciplinary team, thorough patient evaluation, careful preparation and rigorous patient monitoring. Many patients are candidates for multiple treatment approaches; we generally employ CPX-351 (Vyxeos®) as an intensive outpatient approach and venetoclax (Venclyxto/Venclexta®) plus hypomethylating agents as a lower-intensity approach, with 2-3 visits/week during treatment.
