B-Lymphoblastic Leukemia with BCR::ABL1-like Features After Long-term Lenalidomide Therapy.

Lenalidomide, a derivative of thalidomide, is a type of immunomodulatory drug (IMiD) that has been standard therapy for multiple myeloma (MM) and other hematologic malignancies for almost two decades. The success of these drugs in MM has contributed to increased survival of patients and, as a result, patients are at risk for a secondary primary malignancy (SPM), some of which occur as a result of treatment for MM. MM patients have an increased risk for acute myeloid leukemia (AML) and Kaposi sarcoma.

Clinical outcomes of patients diagnosed with mutated myeloid neoplasms.

SETBP1 mutations (m) have been previously reported in myeloid neoplasms and are associated with poor prognostic co-mutations and cytogenetic abnormalities. We retrospectively analyzed the charts of 113 patients diagnosed with myeloid neoplasms with SETBP1m. The most common diagnosis was MDS (31%).

Predictors of Local Control With Palliative Radiotherapy for Multiple Myeloma.

Introduction: We performed a retrospective analysis of patients with multiple myeloma (MM) receiving palliative radiotherapy (RT) and assessed factors associated with local control, with a focus on dose/fractionation and cytogenetics.

Materials And Methods: We included patients who received palliative RT for MM at our institution. Cytogenetics were collected via fluorescence in situ hybridization.
