CarT multiple myeloma

Amyloidosis is a group of diseases characterized by an irreversible and extracellular deposition of fibrillar, amorphous protein known as amyloid in different organs and tissues. Amyloid deposits may occur locally in tissues or may involve various organs, resulting in a wide range of clinical manifestations. Amyloidosis of the head and neck is rarely seen and can reflect some plasma cell dyscrasia that affects B lymphocytes. Deposition of amyloid on the tongue is very rare and accounts for less than 9% of all types of amyloidosis...

The novel clinical data for myeloma that were presented in the 2017 Annual Meeting of the American Society of Hematology are summarized here. Studies with curative approach (CESAR) or prolonging progression-free survival (CENTAURUS) for patients with high-risk smoldering multiple myeloma (SMM) are described. Updated data from large phase III studies for patients with newly diagnosed MM (NDMM) who are eligible for autologous stem cell transplantation (ASCT) (EMN02, MRC XI) are described, along with the results of studies using novel anti-myeloma drug combinations for induction, consolidation, and maintenance as first-line therapy...

Chimeric antigen receptor T cell (CART) therapy has dramatically changed the therapeutic prospects for B cell malignancies. Over the last decade CD19-redirected CART have demonstrated the ability to induce deep, long-lasting remissions and possibly cure patients with relapsing B cell neoplasms. Such impressive results with CART19 fostered efforts to expand this technology to other incurable malignancies that naturally do not express CD19, such as acute myeloid leukemia (AML), Hodgkin lymphoma (HL) and multiple myeloma (MM)...

Myelomatous pleural effusion is a very rare presentation of multiple myeloma. A 65-year-old male patient presented to us with complaints of dyspnea and left-sided chest pain. His contrast enhanced computed tomography of the thorax showed left-sided pleural effusion with multiple pleural nodules. His pleural fluid cytology shows malignant plasma cells with eccentric nuclei and cart wheel chromatin and a few cells showing binucleation and multinucleation suggestive of plasma cell myeloma. His pleural fluid and serum electrophoresis showed a distinct band in the gamma globulin region (M-spike)...

BACKGROUND: Treatment of B cell malignancies with adoptive transfer of T cells with a CD19-specific chimeric antigen receptor (CAR) shows remarkable clinical efficacy. However, long-term persistence of T cells targeting CD19, a pan-B cell marker, also depletes normal B cells and causes severe hypogammaglobulinemia. Here, we developed a strategy to target B cell malignancies more selectively by taking advantage of B cell light Ig chain restriction. We generated a CAR that is specific for the κ light chain (κ...

Chimeric antigen receptors redirect T cells to surface antigens. Discovery and validation of appropriate target antigens expands the possible indications for chimeric-antigen receptor (CAR) T cells. CS1 is expressed at high levels by multiple myeloma cells, but also to some extent on other lymphocytes. CS1 may be a viable target for CAR T cells in multiple myeloma.

The DNA microarray technology enables the identification of the large number of genes involved in the complex deregulation of cell homeostasis taking place in cancer. Using Affymetrix microarrays, we have compared the gene expression profiles of highly purified malignant plasma cells from nine patients with multiple myeloma (MM) and eight myeloma cell lines to those of highly purified nonmalignant plasma cells (eight samples) obtained by in vitro differentiation of peripheral blood B cells. Two unsupervised clustering algorithms classified these 25 samples into two distinct clusters: a malignant plasma cell cluster and a normal plasma cell cluster...

A method is developed for obtaining tree-structured relative risk estimates for censored survival data. The first step of a full likelihood estimation procedure is used in a recursive partitioning algorithm that adopts most aspects of the widely used Classification and Regression Tree (CART) algorithm of Breiman et al. (1984, Classification and Regression Trees, Belmont, California: Wadsworth). The performance of the technique is investigated through stimulation and compared to the tree-structured survival methods proposed by Davis and Anderson (1989, Statistics in Medicine 8, 947-961) and Therneau, Grambsch, and Fleming (1990, Biometrika 77, 147-160)...
