Cytokine-mediated CAR T therapy resistance in AML.

Acute myeloid leukemia (AML) is a rapidly progressive malignancy without effective therapies for refractory disease. So far, chimeric antigen receptor (CAR) T cell therapy in AML has not recapitulated the efficacy seen in B cell malignancies. Here we report a pilot study of autologous anti-CD123 CAR T cells in 12 adults with relapsed or refractory AML.

Characteristics and risk factors for thrombosis in POEMS syndrome: A retrospective evaluation of 230 patients.

Thromboses are prevalent in POEMS syndrome, but few risk factors for POEMS-associated thrombosis have been identified. The objective of this study is to identify novel risk factors for POEMS-associated thrombosis. In this retrospective cohort of 230 POEMS patients, 27% developed thrombosis.

MASS-FIX for the detection of monoclonal proteins and light chain N-glycosylation in routine clinical practice: a cross-sectional study of 6315 patients.

Immunoenrichment-based matrix assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS), termed MASS-FIX, offers several advantages over immunofixation for the detection and isotyping of serum monoclonal protein, including superior sensitivity and specificity, the ability to differentiate therapeutic monoclonal antibodies, and the rapid identification of light chain (LC) N-glycosylation. We identified 6315 patients with MASS-FIX performed at our institution since 2018. Of these, 4118 patients (65%) with a wide array of plasma cell disorders (PCD), including rare monoclonal gammopathies of clinical significance, had a positive MASS-FIX.

Metaphase cytogenetics and plasma cell proliferation index for risk stratification in newly diagnosed multiple myeloma.

Metaphase cytogenetic abnormalities, plasma cell proliferation index (PCPro), and gain 1q by fluorescence in situ hybridization (FISH) are associated with inferior survival in newly diagnosed multiple myeloma (MM) treated with novel agents; however, their role in risk stratification is unclear in the era of the revised International Staging System (R-ISS). The objective of this study was to determine if these predictors improve risk stratification in newly diagnosed MM when accounting for R-ISS and age. We studied a retrospective cohort of 483 patients with newly diagnosed MM treated with proteasome inhibitors and/or immunomodulators.

Development of thrombocytopenia during first-line treatment and survival outcomes in newly diagnosed multiple myeloma.

The prognostic significance of novel agent-induced thrombocytopenia in newly diagnosed multiple myeloma (MM) is unknown. We identified 665 newly diagnosed patients receiving proteasome inhibitors and/or immunomodulators with pretreatment platelet counts ≥100,000/µL. Median progression-free survival (PFS) was 1.

Time to plateau as a predictor of survival in newly diagnosed multiple myeloma.

Response rates in newly diagnosed multiple myeloma have improved dramatically with the introduction of highly effective novel therapies. However, survival in patients achieving optimal responses to initial treatment can vary significantly, and new prognostic indicators are required to improve risk stratification. We investigated the relationship between time to plateau (T ) and survival in 1099 newly diagnosed patients treated with novel agents at our institution from 2005 to 2015.
