Consensus recommendations on the management of toxicity associated with CD3×CD20 bispecific antibody therapy.

Bispecific antibodies (BsAb) that target CD3 and CD20 represent a new milestone in the treatment of patients with B-cell non-Hodgkin lymphoma. These drugs have demonstrated remarkable single-agent activity in patients with heavily pretreated disease, and 3 drugs have so far received regulatory approvals in various countries. However, BsAbs can potentially lead to severe toxicity associated with T-cell activation, particularly cytokine release syndrome (CRS).

Results from a Real-World Multicenter Analysis of 482 Patients with Chronic Lymphocytic Leukemia Treated with Ibrutinib: A Look at Racial Differences.

Background: Despite recent approvals of lifesaving treatments for chronic lymphocytic leukemia (CLL), real-world data on the tolerability of the Bruton tyrosine kinase inhibitor ibrutinib for CLL treatment are lacking, especially in Black patients.

Objective: To expand upon a previously reported retrospective chart review of ibrutinib-treated patients with CLL to increase the number of sites and the enrollment period in first-line (1L) and relapsed/refractory (R/R) settings with a subanalysis based on ethnicity.

Patients And Methods: Adults with CLL who initiated ibrutinib treatment from five centers were followed for ≥ 6 months.

CNS relapse in patients with DLBCL treated with lenalidomide plus R-CHOP (R2CHOP): analysis from two phase 2 studies.

Central nervous system (CNS) relapse of diffuse large B-cell lymphoma (DLBCL) is a devastating event occurring in ~ 5% of patients treated with R-CHOP. We hypothesized that adding lenalidomide to R-CHOP (R2CHOP) may decrease the risk of CNS relapse. We analyzed records for patients with DLBCL from two R2CHOP trials.

Functional and clinical relevance of VLA-4 (CD49d/CD29) in ibrutinib-treated chronic lymphocytic leukemia.

The Bruton's tyrosine kinase (BTK) inhibitor ibrutinib, which antagonizes B cell receptor (BCR) signals, demonstrates remarkable clinical activity in chronic lymphocytic leukemia (CLL). The lymphocytosis experienced by most patients under ibrutinib has previously been attributed to inhibition of BTK-dependent integrin and chemokine cues operating to retain the tumor cells in nodal compartments. Here, we show that the VLA-4 integrin, as expressed by CD49d-positive CLL, can be inside-out activated upon BCR triggering, thus reinforcing the adhesive capacities of CLL cells.

Management of patients with chronic lymphocytic leukemia at high risk of relapse on ibrutinib therapy.

The past two decades have witnessed a paradigm shift in the management of patients with chronic lymphocytic leukemia (CLL), particularly with the introduction of targeted therapies to clinical practice. Ibrutinib is an irreversible inhibitor of Bruton's tyrosine kinase (BTK) and has shown significant efficacy and tolerability, even in heavily treated patients. Despite improvement in outcomes, patients do ultimately relapse.

Frequency, risk factors, and outcomes of central nervous system relapse in lymphoma patients treated with dose-adjusted EPOCH plus rituximab.

Background: Central nervous system (CNS) relapse in non-Hodgkin lymphoma (NHL) is a rare but serious complication that carries a poor prognosis. The use of infusional etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (EPOCH-R) for frontline treatment of diffuse large B cell lymphoma (DLBCL) is increasing, though little is known about incidence of and risk factors for CNS relapse with this regimen PATIENTS AND METHODS: We completed a chart review of patients with NHL who received EPOCH-R as front line therapy. Data obtained included baseline and treatment characteristics including if patients received CNS directed therapy.

Immunotherapy for multiple myeloma: Current status and future directions.

Multiple myeloma (MM) is a plasma cell neoplasm which constitutes about 10% of all hematologic malignancies and has been in the limelight of fast-track development of novel drugs that have contributed to the transformation of a rapidly lethal disease into a chronic illness with significant improvement in quality of life. Nonetheless, MM remains an incurable disease in many patients. Immunotherapy has been one of the approaches that had the highest hope for curing this disease.

Interobserver variability of mitotic index and utility of PHH3 for risk stratification in gastrointestinal stromal tumors.

Objectives: Accurate grading of gastrointestinal stromal tumors (GISTs), based on mitotic index, can be problematic.

Methods: In this study, we compared interobserver variability in detecting mitosis on H&E with PHH3 immunohistochemistry (IHC). In addition, we examined the correlation between H&E mitosis and Ki-67 and the association of PHH3 and Ki-67 with overall survival.

Relationship of serum imatinib trough level and response in CML patients: long term follow-up.

One hundred and three patients with Philadelphia chromosome or BCR-ABL positive chronic myeloid leukemia (CML) in chronic phase who were on oral imatinib were included in this study. The study aimed to assess the relationship between imatinib trough serum levels and clinical outcome (as determined by molecular response) in Jordanian CML patients who have been on imatinib therapy for at least 12 months. The mean trough imatinib serum level in the group with complete molecular response (CMR) was 2891±856 ng/ml, the group with major molecular response (MMR) was 2337±434 ng/ml, the group with complete cytogenetic response (CCyR) was 1817±563 ng/ml, and the group without CCyR was 1723±673 ng/ml.
