ConclusionsSamalizumab had a good safety profile and treatment was associated with reduced tumor burden in a majority of patients with advanced CLL. These preliminary positive results support further development of samalizumab as an immune checkpoint inhibitor.Trial registrationClinicalTrials.gov,NCT00648739 registered April 1, 2008.

We examined the impact of epitype in 1286 CLL patients from 4 independent cohorts representing a comprehensive view of CLL disease course and therapies. We found that epitype significantly predicted TTFT and OS among newly diagnosed CLL patients. Additionally, epitype predicted TTP and OS with 2 common CLL therapies: chemoimmunotherapy and ibrutinib. Epitype retained significance after stratifying by biologically related biomarkers, immunoglobulin heavy chain mutational status, and ZAP70 expression, as well as other common prognostic markers. Furthermore, among several biological traits enriched between epitypes, we found ...

eckman CA Abstract Innate drug sensitivity in healthy cells aids identification of lineage specific anti-cancer therapies and reveals off-target effects. To characterize the diversity in drug responses in the major hematopoietic cell types, we simultaneously assessed their sensitivity to 71 small molecules utilizing a multi-parametric flow cytometry assay and mapped their proteomic and basal signaling profiles. Unsupervised hierarchical clustering identified distinct drug responses in healthy cell subsets based on their cellular lineage. Compared to other cell types, CD19+/B and CD56+/NK cells were more sensitive ...

CONCLUSIONS: Further research is required in this area to establish prognostic and management recommendations. Increasing numbers of cases are being described. Positron emission tomography with computed tomography was not useful in our cohort for diagnosing progression. PMID: 31433844 [PubMed - as supplied by publisher]

Auer rods were first described in the cytoplasm of leukemia blasts by John Auer in 1906. Auer rods are commonly seen in myeloid progenitors, and serve as a diagnostic morphological feature of acute myeloid leukemia (AML) [1]. The differential diagnosis of hematopoietic neoplasms relies on the detection of cytoplasmic inclusions resembling Auer rods. Auer rod-like inclusions have been described in multiple myeloma [2], prolymphocytic leukemia (PLL) [3], B-cell acute lymphoblastic leukemia [4], chronic lymphocytic leukemia [4], splenic lymphoma [5] and nodal marginal zone lymphoma [6], which are quite distinct from the needl...
