Cll stem cell transplant

OBJECTIVE: This study assessed healthcare costs of first-line treatment failure (TF) in patients with chronic lymphocytic leukemia (CLL), a subtype of non-Hodgkin's lymphoma. METHODS: Pre-diagnosis treatment-naïve adults with ≥2 CLL diagnoses initiated on an antineoplastic agent (index date) after their first CLL diagnosis with ≥12 and ≥6 months of continuous observation pre- and post-index, respectively, were selected from the Truven Health MarketScan® Research Databases...

OBJECTIVE: To describe the characteristics of patients suffering from secondary immunodeficiencies (SID) associated with hematological malignancies (HM), who started immunoglobulins replacement therapy (IgRT), physicians' expectations regarding IgRT and IgRT modalities. METHODS: Non-interventional, prospective French cross-sectional study. RESULTS: The analysis included 231 patients (66±12 years old) suffering from multiple myeloma (MM) (N=64), chronic lymphoid leukemia (CLL) (N=84), aggressive non-Hodgkin B-cell lymphoma (aNHL) (N=32), indolent NHL (N=39), acute leukemia (N=6), Hodgkin disease (N=6)...

Infections are one of the most common causes of mortality in immunocompromised patients. In patients diagnosed with hematologic malignancies, treatment with stem cell transplants (SCT) or T-cell suppressing chemotherapy increases the risk of central nervous system (CNS) infections, of which toxoplasmosis is the most common. We report the case of a 63 year-old woman with chronic lymphocytic leukemia (CLL) that presented with gait instability and visual changes. Intracranial lesions were noted on initial neuro-imaging...

Context: This named patient program evaluated the safety and efficacy of ibrutinib, a selective inhibitor of Bruton's tyrosine kinase in Indian patients with relapsed/refractory chronic lymphocytic leukemia (CLL, with/without chromosome 17 deletion [del17p]) and mantle cell lymphoma (MCL). Subjects and Methods: The eight enrolled patients (relapsed/refractory CLL: n = 6 [4/6 patients with del17p] and relapsed/refractory MCL: n = 2) had median age of 55 years (range, 52-60) and had received a median of 3 (CLL patients) and 4 (MCL patients) prior therapies...

The treatment landscape of chronic lymphocytic leukemia (CLL) has been challenged by the advent of novel classes of drugs, such as B-cell receptor (BCR)-inhibitors and BCL-2 antagonists. In selected high-risk patients, the choice to start allogeneic hematopoietic stem cell transplantation (alloHCT) or continue these agents is a matter of debate. Furthermore, published data about the impact on the feasibility of alloHCT and the optimal timing of administration are limited. Here we present a case of relapsed TP53 mutated CLL treated with ibrutinib as a bridge to alloHCT, discussing risks and benefits of different treatment options in a "real life" situation...

Based on the available literature, mostly derived from retrospective or non-randomized phase I or II studies, it is difficult to define an optimized treatment approach for patients developing Richter's syndrome (RS). Early recognition of chronic lymphocytic leukemia (CLL) patients presenting clinical features suspected for a transformation is useful to avoid exposing them to multiple lines of therapy that, being targeted to CLL progression, have poor efficacy against RS. Because of the low specificity (~ 50-60%) of clinical signs of RS (such as rapid and discordant bulky localized lymphadenopathies, elevated LDH levels, emergent physical deterioration, and/or fever in the absence of infection), a 18 FDG PET/CT and a biopsy are recommended to confirm RS...

Limited studies have reported on outcomes for lymphoid malignancy patients receiving alternative donor allogeneic stem cell transplants. We have previously described combining CD34-selected haploidentical grafts with umbilical cord blood (haplo-cord) to accelerate neutrophil and platelet engraftment. Here, we examine the outcome of patients with lymphoid malignancies undergoing haplo-cord transplantation at the University of Chicago and Weill Cornell Medical College. We analyzed 42 lymphoma and chronic lymphoblastic leukemia (CLL) patients who underwent haplo-cord allogeneic stem cell transplantation...

Purpose: We determined the safety, pharmacokinetics, pharmacodynamics and recommended phase II dose of the base excision repair blocker methoxyamine combined with fludarabine. Materials and Methods: This was a phase I study with intravenous fludarabine (25 mg/m2 , days 1-5), and methoxyamine (15 mg/m2 -120 mg/m2 , once). A maximum of six cycles were given. Adult patients with relapsed/refractory hematologic malignancies, excluding acute myeloid leukemia, were eligible...

INTRODUCTION: In recent years, considerable progress has been made in the treatment of patients with chronic lymphocytic leukemia (CLL), and new potent drugs have become available. Therefore, the CLL working party revised the Dutch guidelines. Not only efficacy but also quality of life and socio-economic impact were taken into account in the formulation of treatment recommendations. MATERIALS AND METHODS: The working party discussed a set of questions regarding diagnostic tests and treatment and wrote the draft guideline...

Chronic lymphocytic leukemia (CLL) has a highly variable clinical course. About 2-10% of CLL patients develop aggressive histological transformation, most commonly to diffuse large B cell lymphoma (DLBCL), historically called Richter transformation (RT). Clinical features suggestive of RT include elevated LDH and non-specific symptoms such as fever, weight loss, and lymphadenopathy. 18-fluorodeoxyglucose (18-FDG) uptake is increased on PET scan (standardized uptake value max most commonly ≥ 10). PET/CT study can identify optimal site for excisional biopsy, which is the gold standard for RT diagnosis, as well as aid in disease staging and prognostication...

Chronic lymphocytic leukemia (CLL) is a common hematologic malignancy with many highly effective therapies. Chemorefractory disease, often characterized by deletion of chromosome 17p, has historically been associated with very poor outcomes, leading to the application of allogeneic hematopoietic stem cell transplantation (allo-HCT) for medically fit patients. Although the use of allo-HCT has declined since the introduction of novel targeted therapy for the treatment of CLL, there remains significant interest in understanding factors that may influence the efficacy of allo-HCT, the only known curative treatment for CLL...

Chronic lymphocytic leukemia (CLL) is characterized by clonal proliferation and accumulation of mature CD5-positive, CD10-negative, CD20 weakly positive, and CD23-positive B-cells within blood, bone marrow, lymph nodes, and spleen. In proliferation centers, the survival and growth of CLL cells requires a permissive microenvironment comprising T-cells, macrophages, and stromal cells. FISH analysis has revealed that almost 80% of CLL cases carry chromosomal abnormalities including the most frequent del (13q14) and the strongest poor prognostic factor del (17p), both related to TP53 mutations...

Secondary neoplasias are well known consequences of radiotherapy or chemotherapy for a primary cancer. In this report, we describe two rare secondary neoplasias occurring in the same patient: a meningioma-like intracranial tumor and high-risk myelodysplastic syndrome (MDS) of donor-cells origin, both diagnosed simultaneously, 8 years after an allogeneic hematopoietic stem cell transplantation (allo-HSCT) for chronic lymphocytic leukemia (CLL). Due to an engraftment failure during the first allo-HSCT of a matched related donor for CLL treatment, the salvage treatment was a second allo-HSCT...

The treatment landscape for chronic lymphocytic leukemia (CLL) is changing rapidly. Novel targeted agents such as ibrutinib, venetoclax, and idelalisib have had a significant effect on first-line, relapsed/refractory, and high-risk disease. Despite these advances, there are continuous needs for new treatment options, especially for patients in whom these novel therapies fail or those who cannot tolerate these novel therapies. In 2011, Porter et al reported the first successful use of autologous chimeric antigen receptor T cells (CARTs) directed against cluster of differentiation (CD)19 in 3 refractory CLL patients...

BACKGROUND: Patients with genetically high-risk relapsed/refractory chronic lymphocytic leukemia have shorter median progression-free survival (PFS) with kinase- and BCL2-inhibitors (KI, BCL2i). Allogeneic hematopoietic stem cell transplantation (alloHCT) may result in sustained PFS, especially in younger patients because of its age-dependent non-relapse mortality (NRM) risk, but outcome data are lacking for this population. PATIENTS AND METHODS: Risk factors for 2-year NRM and 8-year PFS were identified in patients < 50 years in an updated European Society for Blood and Marrow Transplantation registry cohort (n = 197; median follow-up, 90...

Patients with chronic lymphocytic leukemia (CLL) who progress to Richter transformation (RT) have a poor prognosis. Multi-agent chemotherapy regimens do not have good response rates. There are few case reports on the use of ibrutinib in RT. Here, we present a patient who was heavily pretreated for CLL, including allogeneic stem cell transplant, and progressed to RT. She had a mixed response to multi-agent chemotherapy and was started on ibrutinib. She had a complete response for 16 months on single-agent ibrutinib with minimal toxicity...

The role of cutaneous viral infections in the development of non-melanoma skin cancer (NMSC), including cutaneous squamous cell carcinoma (SCC), among chronic lymphocytic leukemia (CLL) and blood and marrow transplant (BMT) patients is not established. CLL (n = 977) and BMT (n = 3587) patients treated at the Moffitt Cancer Center were included in a retrospective cohort study. Human papillomavirus (HPV) and human polyomavirus (HPyV) DNA were examined in a subset of incident SCC tumors. Five-year cumulative incidence of NMSC was 1...

The best approach for allogeneic haematopoietic stem cell transplantations (alloHCT) in patients with chronic lymphocytic leukaemia (CLL) is unknown. We therefore analysed the impact of procedure- and centre-related factors on 5-year event-free survival (EFS) in a large retrospective study. Data of 684 CLL patients who received a first alloHCT between 2000 and 2011 were analysed by multivariable Cox proportional hazards models with a frailty component to investigate unexplained centre heterogeneity. Five-year EFS of the whole cohort was 37% (95% confidence interval [CI], 34-42%)...

The B-cell receptor (BCR) pathway plays an important role in the survival, proliferation and trafficking of cancer cells in a variety of B-cell malignancies. Recently, a number of agents have been developed to target various components of the BCR pathway. One such target is Bruton's tyrosine kinase (BTK), a Tec family kinase member found near the cell membrane that is involved in upstream BCR signaling. The biological function of BTK in several B-cell lymphoid malignancies has led to the development of the oral BTK inhibitor ibrutinib...

In patients with chronic lymphocytic leukemia (CLL), persistence of disease after allogeneic stem cell transplantation (alloSCT) can result in poor outcomes. In an effort to improve these outcomes, patients with persistent CLL who were 90 to 100 days beyond alloSCT with no evidence of graft-versus-host-disease (GVHD) were randomized to receive lenalidomide or standard care (withdrawal of immunosuppression followed by donor lymphocyte infusion). Lenalidomide was initiated at 5 mg every other day and increased to 10 mg daily, if tolerated, in each patient...
