Carfilzomib, lenalidomide, and dexamethasone in relapsed refractory multiple myeloma: a prospective real-life experience of the Regional Tuscan Myeloma Network.

Introduction: Carfilzomib, a potent, irreversible, selective proteasome inhibitor has demonstrated consistent results in relapsed/refractory multiple myeloma (RRMM) combined with lenalidomide and dexamethasone (KRd). No prospective studies are yet available that analyzed the efficacy of the KRd combination.

Methods: Herein, we report a multicenter prospective observational study on 85 patients who were treated with KRd combination as the second or third line of treatment, according to standard practice.

Daratumumab in AL Amyloidosis: A Real-Life Experience of the "RTM" (Regional Tuscan Myeloma Network).

Systemic amyloidosis arises from monoclonal CD38+ plasma cells that produce misfolded immunoglobulin light chains, which form amyloid fibrils that are deposited into different tissues, leading to organ damage. Daratumumab is a human IgG/k monoclonal antibody that targets CD38, a glycoprotein uniformly expressed on human plasma cells. Daratumumab has been utilized in recent years with unprecedented responses in multiple myeloma.

Real-Life Experience with Pomalidomide plus Low-Dose Dexamethasone in Patients with Relapsed and Refractory Multiple Myeloma: A Retrospective and Prospective Study.

The treatment of Myeloma after the second relapse is still challenging. The aim of the study was to investigate the outcomes of the POM-DEX regimen in real clinical practice. We retrospectively and prospectively analyzed 121 patients with MM treated with POM-DEX in three Italian sites in Tuscany.

Ectopic ILT3 controls BCR-dependent activation of Akt in B-cell chronic lymphocytic leukemia.

The high proportion of long-term nonprogressors among chronic lymphocytic leukemia (CLL) patients suggests the existence of a regulatory network that restrains the proliferation of tumor B cells. The identification of molecular determinants composing such network is hence fundamental for our understanding of CLL pathogenesis. Based on our previous finding establishing a deficiency in the signaling adaptor p66Shc in CLL cells, we undertook to identify unique phenotypic traits caused by this defect.

Bruton Kinase Inhibitors in Chronic Lymphocytic Leukemia.

Abnormality of the B-cell receptor (BCR) signaling is correlated to origin of many B-cell malignancies. Bruton's tyrosine kinase (BTK), is described as a possible target in a many B-cell neoplasms. Ibrutinib is the most used inhibitor of BTK and has great tolerability and efficacy in chronic lymphocytic leukemia.

Second Generation Proteasome Inhibitors in Multiple Myeloma.

Bortezomib was the first proteasome inhibitor (PI) discovered and demonstrated great efficacy in myeloma, both in vitro and in patients. However, still many patients ultimately relapse and there is the need for novel therapies. A second generation of PI have been discovered, potentially more effective ands some also orally administered.

Human Cytotoxic T Lymphocytes Form Dysfunctional Immune Synapses with B Cells Characterized by Non-Polarized Lytic Granule Release.

Suppression of the cytotoxic T cell (CTL) immune response has been proposed as one mechanism for immune evasion in cancer. In this study, we have explored the underlying basis for CTL suppression in the context of B cell malignancies. We document that human B cells have an intrinsic ability to resist killing by freshly isolated cytotoxic T cells (CTLs), but are susceptible to lysis by IL-2 activated CTL blasts and CTLs isolated from immunotherapy-treated patients with chronic lymphocytic leukemia (CLL).

Evolving treatments in multiple myeloma patients with renal failure.

The introduction of novel agents in multiple myeloma therapy has dramatically improved survival in latest years. Great progress has also been detected in particular poor clinical situation such as acute renal failure in which survival was dismal in the past. Treatment with bortezomib, thalidomide and dialysis associated with high cut-off (HCO) filters can recover more than two thirds of myeloma patients with an end stage renal failure.

Therapeutic advancements in multiple myeloma.

Multiple myeloma survival has significantly improved in the latest years due to a broad spectrum of novel agents available for treatment. The introduction of thalidomide, bortezomib, and lenalidomide together with autologous stem-cell transplantation has considerably increased complete remission rate and progression-free survival resulting ultimately in prolonged survival in myeloma patients. Moreover, novel strategies of treatment such as consolidation and maintenance are being used to further implement responses.

Chemoimmunotherapy with oral low-dose fludarabine, cyclophosphamide and rituximab (old-FCR) as treatment for elderly patients with chronic lymphocytic leukaemia.

Median age at diagnosis for chronic lymphocytic leukaemia (CLL) patients is now 72 years, thus a consistent number of patients may not tolerate standard doses i.v. of fludarabine, cyclophosphamide and rituximab (FCR), the best available therapy, due to unacceptable myelotoxicity and risk of severe infections.
