Chromosomal rearrangements (CR) initiate leukemogenesis in approximately 50 % of acute myeloid leukemia (AML) patients; however, limited targeted therapies exist due to a lack of accurate molecular and genetic biomarkers of refractory mechanisms during treatment. Here, we investigated the pathological landscape of treatment resistance and relapse in 16 CR-AML patients by monitoring cytogenetic, RNAseq, and genome-wide changes among newly diagnosed, refractory, and relapsed AML. First, in FISH-diagnosed KMT2A (MLL gene, 11q23)/AFDN (AF6, 6q27)-rearrangement, RNA-sequencing identified an unknown CCDC32 (15q15.

Inotuzumab ozogamicin (InO) has been combined with low-intensity chemotherapy, with modest improvements over historical controls, and dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (DA-EPOCH) treatment is safe and active for newly diagnosed ALL.
Objective: To assess the safety and clinical activity of DA-EPOCH and InO in adults with relapsed or refractory B-ALL.
Objectives: We recently performed a single-arm phase II trial of DA-EPOCH in adults with acute lymphoblastic leukemia (ALL). We sought to compare these results to those with standard Hyper-CVAD.
Methods: We created a retrospective matched cohort of patients who received Hyper-CVAD (n = 69) at our center and otherwise met eligibility criteria for the DA-EPOCH trial (n = 53).
Persistent symptomatic coronavirus disease 2019 (COVID-19) is a distinct clinical entity among patients with hematologic cancer and/or profound immunosuppression. The optimal medical management is unknown. We describe 2 patients who had symptomatic COVID-19 for almost 6 months and were successfully treated in the ambulatory setting with extended courses of nirmatrelvir-ritonavir.

Here, we evaluated adding sorafenib to cladribine, high-dose cytarabine, granulocyte colony-stimulating factor, and mitoxantrone (CLAG-M) in a phase 1/2 trial of 81 adults aged ≤60 years with newly diagnosed AML. Forty-six patients were treated in phase 1 with escalating doses of sorafenib and mitoxantrone.

Twenty days of nirmatrelvir/ritonavir and 10 days of IV remdesivir led to full recovery.

ATO is converted from inorganic arsenic (iAs) to methylated (MAs) and dimethylated (DMAs) metabolites, which are excreted in the urine. Methylation of iAs is important in detoxification, as iAs exposure is deleterious to health.

Twenty-seven patients receiving ATO during induction were categorized as obese ( = 16) or non-obese ( = 11) based on body mass index (BMI) ≥30 kg/m in this retrospective study. Doses were held or modified due to composite adverse effects in 9 (56%) obese patients and 7 (64%) non-obese patients ( = 1.

Acute pancreatitis is one of the rare complications that is reported with vemurafenib use. As severe pancreatitis can be life threatening, physicians should be vigilant of this side effect and promptly treat patients that develop clinical signs and symptoms while receiving vemurafenib.

Since the International Randomized Study of Interferon and STI571 trial (IRIS trial) in 2003, treatment with tyrosine kinase inhibitors (TKIs) has become the standard of care for patients with newly diagnosed CML in the chronic phase. Dasatinib is a second-generation TKI and is generally well tolerated, with cytopenias, gastrointestinal (GI) symptoms and fluid retention being the most commonly observed side effects.

Proximal tubules are a target for paraproteinemic diseases. Cast nephropathy, light chain deposition diseases, and amyloidosis are frequently encountered in patients with multiple myeloma. Rarely, a subset of patients develop light chain Fanconi syndrome (LCFS).
