Patients taking imatinib (Gleevec) for CML, or chronic myelogenous leukemia, and in remission after two years of treatment, have a mortality rate similar to that of the general population, according to a new study. The article offers the first evidence that a disseminated cancer, not amenable to surgery, can be controlled to the point of giving patients a normal life expectancy.

Nonspecific Capillary Proliferation and Vasculopathy Indicate Skin Hypoxia in Erythromelalgia [Study]

Posted by rob on under Uncategorized | Comments are off for this article

Conclusions  Histopathologic analysis is not useful as a routine diagnostic tool in EM because no morphological changes are specific to EM. The capillary proliferation and vasculopathy are assumed to be a consequence of intermittent skin hypoxia (vascular hypothesis of pathogenesis). Whether the proliferation is a consequence of EM or a pathogenic factor in the development of the disease is uncertain. (Source: Archives of Dermatology)

Imatinib mesylate versus allogeneic hematopoietic stem cell transplantation for patients with chronic myelogenous leukemia in the accelerated phase

Posted by rob on under Uncategorized | Comments are off for this article

The relative merits of allogeneic hematopoietic stem cell transplantation (allo-HSCT) and imatinib for chronic myelogenous leukemia in the accelerated phase (AP-CML) have not previously been evaluated. This cohort study was designed to compare the outcomes of imatinib (n = 87) versus allo-HSCT (n = 45) for AP-CML. A multivariate analysis of the total population revealed that a CML duration ≥ 12 months, hemoglobin < 100 g/L, and peripheral blood blasts ≥ 5% were independent adverse prognostic factors for both overall survival (OS) and progression-free survival (PFS). Both treatments resulted in similar survival in low-risk (no factor) patients, with 6-year event-free survival (EFS), OS, and PFS rates of more than 80.0%. Intermediate-risk (any factor) patients showed no difference i…

Bcr-Abl ubiquitination and Usp9x inhibition block kinase signaling and promote CML cell apoptosis

Posted by rob on under Uncategorized | Comments are off for this article

We describe a novel approach to targeting key proteins in CML cells with a ubiquitin-cycle inhibitor, WP1130. Bcr-Abl is rapidly modified with K63-linked ubiquitin polymers in WP1130-treated CML cells, resulting in its accumulation in aggresomes, where is it unable to conduct signal transduction. Induction of apoptosis because of aggresomal compartmentalization of Bcr-Abl was observed in both imatinib-sensitive and -resistant cells. WP1130, but not Bcr-Abl kinase inhibitors, directly inhibits Usp9x deubiquitinase activity, resulting in the down-regulation of the prosurvival protein Mcl-1 and facilitating apoptosis. These results demonstrate that ubiquitin-cycle inhibition represents a novel and effective approach to blocking Bcr-Abl kinase signaling and reducing Mcl-1 levels to engage CML …

Effective posttransplant antitumor immunity is associated with TLR-stimulating nucleic acid-immunoglobulin complexes in humans

Posted by rob on under Uncategorized | Comments are off for this article

Donor lymphocyte infusion (DLI), whereby donor mononuclear cells are infused into patients, is one of the few effective immunotherapeutic strategies that generate long-lasting tumor remissions. We previously demonstrated that chronic myelogenous leukemia (CML) patients treated with DLI develop high-titer plasma antibodies specific for CML-associated antigens, the majority of which have been reported to bind nucleic acids These observations led us to predict that circulating antibody-antigen complexes in DLI-responsive patients carry nucleic acids that can engage innate immune sensors. Consistent with this, we report here that post-DLI plasma from 5 CML patients that responded to DLI treatment induced massive upregulation of MIP-1α, IP-10, and IFN-α in normal blood mononucle…

Down?regulation of thanatos?associated protein 11 by BCR?ABL promotes CML cell proliferation through c?Myc expression

Posted by rob on under Uncategorized | Comments are off for this article

AbstractBcr?Abl activates various signaling pathways in chronic myelogenous leukemia (CML) cells. The proliferation of Bcr?Abl transformed cells is promoted by c?Myc through the activation of Akt, JAK2 and NF??B. However, the mechanism by which c?Myc regulates CML cell proliferation is unclear. In the present study, we investigated the role of thanatos?associated protein 11 (THAP11), which inhibits c?Myc transcription, in CML cell lines and in hematopoietic progenitor cells derived from CML patients. The induction of THAP11 expression by Abl kinase inhibitors in CML cell lines and in CML?derived hematopoietic progenitor cells resulted in the suppression of c?Myc. In addition, over?expression of THAP11 inhibited CML cell proliferation. In colony forming cells derived fr…

Chromosome 20q deletion: a recurrent cytogenetic abnormality in patients with chronic myelogenous leukemia in remission.

Posted by rob on under Uncategorized | Comments are off for this article

We describe 10 patients with CML in hematologic and cytogenetic remission with del(20q) detected by conventional cytogenetics. There were 6 men and 4 women with a median age of 56 years. All patients initially had BCR-ABL1 and t(9;22) (q34;q11.2) and achieved morphologic and cytogenetic remission after therapy. del(20q) was identified before (2/10 [20%]), at the time of (3/10 [30%]), or after (5/10 [50%]) cytogenetic remission and was not associated with morphologic evidence of dysplasia. At last follow-up, no patients had a myelodysplastic syndrome (MDS). Leukocyte and platelet counts were normal; 4 of 10 patients had mild anemia. Nine patients have remained in morphologic and cytogenetic remission with stable del(20q). BCR-ABL1 fusion transcript levels were absent or low (median, 0.01%)….

Chronic Myelogenous Leukemia: Monitoring Response to Therapy

Posted by rob on under Uncategorized | Comments are off for this article

Abstract  Molecular monitoring is a key component of the management of patients with chronic myeloid leukemia. The current recommendation
is that molecular monitoring be performed in place of cytogenetic assessment when a major molecular response (MMR) is achieved.
With the more potent kinase inhibitors nilotinib and dasatinib now approved as front-line therapy, more patients will achieve
an MMR and will benefit from molecular monitoring. There is a strong correlation between certain BCR-ABL1 levels and the cytogenetic response, which means that molecular monitoring may act as a surrogate for cytogenetic response,
but only if the BCR-ABL1 values are converted to the international reporting scale. Furthermore, improvements in the limit of BCR-ABL1 detection and reduction of in…

Annual Clinical Updates in Hematological Malignancies: A Continuing Medical Education Series: Polycythemia vera and essential thrombocythemia: 2011 update on diagnosis, risk?stratification, and management

Posted by rob on under Uncategorized | Comments are off for this article

AbstractDisease overview:Polycythemia vera (PV) and essential thrombocythemia (ET) are myeloproliferative neoplasms primarily characterized by erythrocytosis and thrombocytosis, respectively. Other disease features include leukocytosis, splenomegaly, thrombohemorrhagic complications, vasomotor disturbances, pruritus, and a small risk of disease progression into acute leukemia or myelofibrosis.Diagnosis:Diagnosis is based on JAK2 mutation status (PV and ET), serum erythropoietin (Epo) level (PV), and bone marrow histopathology (ET). The presence of a JAK2 mutation and subnormal serum Epo level confirm a diagnosis of PV. Differential diagnosis in ET should include chronic myelogenous leukemia and prefibrotic myelofibrosis.Risk stratification:Current risk stratification in PV and ET is design…

Drug therapy of cancer

Posted by rob on under Uncategorized | Comments are off for this article

Abstract  Cancer chemotherapy was introduced at the same time as antibacterial chemotherapy but has not been nearly such a success.
However, there is a growing optimism in oncology today due to the introduction of several more or less target-specific drugs
as complements to the conventional cytotoxic drugs introduced half a century ago. The success in the treatment of chronic
myelogenous leukemia by imatinib, inhibiting the bcr-abl-activated tyrosine kinase and thereby interrupting the signal transduction
pathways that lead to leukemic transformation with impressive survival benefit, has paved the way for this new optimism. Another
success story is the introduction of trastuzumab in breast cancers overexpressing the HER-2 receptor. In contrast, there has
been little progres…
