Background: Leukemic transformation is an unfavorable event emerging in a minority of patients with myelofibrosis (MF) and carrying a poor prognosis. Patients with post-MF acute myeloid leukemia (AML) may be treated with curative or noncurative intent, but there is no standard of care. The use of hypomethylating agents has been correlated with limited activity and low overall survival rates, while ruxolitinib has been proven to have modest antileukemic activity.
Case Presentation: In this case study, we present the case of a 67-year-old female patient with post-polycythemia vera MF who developed AML and was successfully treated with a combination of 5-azacytidine and ruxolitinib, without any significant toxicity.
Summary: To our knowledge, this is the first report of a patient with post-MF AML achieving a complete remission with a combination of ruxolitinib and a hypomethylating agent. This combination is actively studied in phase I/II clinical trials and may be proven effective in this hard-to-treat group of patients.

CAR-T Therapy Beyond B-Cell Hematological Malignancies.

January 2025
Hematology, St. Eugenio Hospital, ASL Roma2, 00144 Rome, Italy.
Despite the advances of CAR-T cells in certain hematological malignancies, mostly from B-cell derivations such as non-Hodgkin lymphomas, acute lymphoblastic leukemia and multiple myeloma, a significant portion of other hematological and non-hematological pathologies can benefit from this innovative treatment, as the results of clinical studies are demonstrating. The clinical application of CAR-T in the setting of acute T-lymphoid leukemia, acute myeloid leukemia, solid tumors, autoimmune diseases and infections has encountered limitations that are different from those of hematological B-cell diseases. To overcome these restrictions, strategies based on different molecular engineering platforms have been devised and will be illustrated below.

Perturbations in intermediary metabolism contribute to the pathogenesis of acute myeloid leukemia (AML) and can produce therapeutically actionable dependencies. Here, we probed whether alpha-ketoglutarate (aKG) metabolism represents a specific vulnerability in AML. Using functional genomics, metabolomics, and mouse models, we identified the aKG dehydrogenase complex, which catalyzes the conversion of aKG to succinyl CoA, as a molecular dependency across multiple models of adverse-risk AML.

Background: BCL-2 was the first gene identified to have antiapoptotic effects, and venetoclax is an oral selective BCL-2 inhibitor, which has great potential in the treatment of patients with acute myeloid leukemia (AML) who are not candidates for intensive therapy. Notably, posaconazole, an oral antifungal drug, is also a strong factor that can affect blood venetoclax concentrations. To the best of our knowledge, the relationship between BCL-2 expression, posaconazole, and venetoclax, as well as their influence on treatment efficacy and the prognosis of patients with AML, has not been reported.

Methods: Our study was a retrospective analysis of adult patients hospitalized with a primary diagnosis of ALL or AML, using the Nationwide Inpatient Sample (NIS) database for 2020.
To Cut (Minimally Invasively) Is to Cure: Robotic Lobectomy for Pulmonary Mucormycosis.

Pulmonary mucormycosis is a rapidly progressive and highly morbid disease commonly found in immunosuppressed patients. Rapid diagnosis and treatment are essential, with thoracotomy and video-assisted thoracoscopic surgery techniques previously described for surgical resection of infected lobes. Here we present the case of a patient with acute myeloid leukemia and nonresolving pneumonia treated with robotic left upper lobectomy.
