Background: Thymoma is a rare mediastinal neoplasm originating from thymic epithelial cells, often associated with paraneoplastic syndromes. These syndromes can manifest as a range of autoimmune disorders, including myasthenia gravis, pure red cell aplasia, and aplastic anemia. Clinical trials involving the use of immune checkpoint inhibitors (ICIs) in thymoma have been complicated by a high incidence of immune-related adverse effects (irAEs).

Chimeric antigen receptor T-cell (CAR-T) therapies are effective in many hematologic malignancies; however, adverse events including cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) can affect a significant number of patients. Those who develop refractory CRS or ICANS have few treatment options. Siltuximab, a monoclonal antibody binding circulating interleukin-6, has been proposed to have clinical activity in both CRS and ICANS.

Article Synopsis
  • * In a Phase 2 trial with 20 patients in complete remission, N-803 was administered subcutaneously at day 60 after transplant, leading to enhanced NK cell proliferation and antitumor responses without causing significant immune exhaustion.
  • * Patients receiving more than 4 doses of N-803 experienced a significant decrease in relapse rates over two years, supporting its safety and potential efficacy for preventing relapse in AML and MDS after hematopoietic stem cell transplant.

Article Synopsis
  • Patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) have limited treatment options, prompting the investigation of magrolimab (M) combined with rituximab (R), and M combined with gemcitabine-oxaliplatin (M+R-GemOx) for long-term disease control.
  • In a study involving 132 patients, M+R achieved an objective response rate (ORR) of 24%, while M+R-GemOx showed a higher ORR of 52%, with notable complete response (CR) rates of 12% and 39%, respectively.
  • Both treatments were generally well tolerated, though common side effects included fatigue and anemia, with

Background: mutations (m) define the most treatment-refractory acute myeloid leukemia (AML) subtype. Optimal treatment approaches have not been established in this setting. We reviewed our institutional experience to identify therapy sequencing, treatment response, and survival patterns in these patients.
