Homoharringtonine (HHT) has antileukemic activity in patients with Philadelphia chromosome (Ph) positive chronic myelogenous leukemia (CML). Combinations of HHT, interferon-α (IFN-α), and cytarabine (ara-C) have been studied in various CML phases. The objectives of this study were to evaluate the efficacy and toxicity profiles of a combination regimen of simultaneous HHT and IFN-α therapy in patients with chronic-phase CML who were not exposed ...

Gouty arthritis is caused by the deposition of monosodium urate (MSU) crystals in joints. Despite many treatment options for gout, there is a substantial need for alternative treatments for patients unresponsive to current therapies. Tyrosine kinase inhibitors have demonstrated therapeutic benefit in experimental models of antibody-dependent arthritis and in rheumatoid arthritis in humans, but to date, the potential effects of such inhibitors on gouty arthritis has not been evaluated. Here we demonstrate that treatment with the tyrosine kinase inhibitor imatinib mesylate (imatinib) can suppress inflammation induced by injection of MSU crystals into subcutaneous air pouches or into the ankle joint of wild type mice. Moreover, imatinib treatment also largely abolished the lower levels of inflammation which developed in IL-1R1-/- or KitW-sh/W-sh mice, indicating that this drug can inhibit IL-1-independent pathways, as well as mast cell-independent pathways, contributing to pathology in this model. ...

We read with interest the article by Kim et al.1 in which the authors provided the efficacy and safety data of radotinib (IY5511HCL), an oral BCR-ABL1-specific 2nd generation tyrosine kinase inhibitor (TKI), in 77 patients with chronic phase-chronic myeloid leukemia (CP-CML) in a multinational phase II trial. After a median duration of radotinib exposure of approximately 12 months and a median follow up of 23.4 months, the complete cytogenetic response (CCyR) rate was 47% by 12 months, and the overall and progression-free survival rates at 12 months were 96.1% and 86.3%, respectively. Thrombocytopenia, hepatotoxicity, hyperbilirubinemia and hyperglycemia were the most common hematologic and non-hematologic adverse events (AEs). The authors implied that radotinib was effective and relatively well tolerated in patients with CP-CML, and CCyR rates were higher in patients without BCR-ABL1 mutations.1. Although most of the CP-CML patients do well under imatinib, some of them develop resistance, and ...

N2 - The oxidative cycloaddition of benzamides and alkynes has been developed. The reaction utilizes Rh(III) catalysts in the presence of Cu(II) oxidants, and is proposed to proceed by N-H metalation of the amide followed by ortho C-H activation. The resultant rhodacycle undergoes alkyne insertion to form isoquinolones in good yield. The reaction is tolerant of extensive substitution on the amide, alkyne, and arene, including halides, silyl ethers, and unprotected aldehydes as substituents. Unsymmetrical alkynes proceed with excellent regioselectivity, and heteroaryl carboxamides are tolerated leading to intriguing scaffolds for medicinal chemistry. A series of competition experiments shed further light on the mechanism of the transformation and reasons for selectivity.. AB - The oxidative cycloaddition of benzamides ...

N2 - Gastrointestinal stromal tumor (GIST) is a devastating disease in the metastatic setting, but its natural history has been dramatically altered by the development of small molecule tyrosine kinase inhibitors, most notably imatinib. Although patients with advanced GIST live much longer today than they did in the past, imatinib-refractory disease remains a tremendous problem. For disease that is refractory to imatinib and sunitinib, regorafenib is an excellent option. In this review, we discuss the biology and clinical work establishing regorafenib as the standard of care for advanced GIST refractory to both imatinib and sunitinib..

TY - JOUR. T1 - Nilotinib. T2 - A novel Bcr-Abl tyrosine kinase inhibitor for the treatment of leukemias. AU - Jabbour, Elias. AU - El Ahdab, Samih. AU - Cortes, Jorge. AU - Kantarjian, Hagop. PY - 2008/7/1. Y1 - 2008/7/1. N2 - The successful introduction of the tyrosine kinase inhibitors has initiated a new era in the management of chronic myeloid leukemia (CML). Imatinib mesilate therapy has significantly improved the prognosis of CML. A minority of patients in chronic-phase CML - and more patients in advanced phases - are resistant to imatinib, or develop resistance during treatment. This is attributed, in 40 - 50% of cases, to the development of mutations in the Bcr-Abl tyrosine kinase domain that impair imatinib binding. Nilotinib (Tasigna®) is a novel potent selective oral kinase inhibitor. Preclinical and clinical investigations demonstrate nilotinib effectively overcomes imatinib resistance, and has induced high rates of hematologic and cytogenetic responses in CML post imatinib ...

B cell lineage acute lymphoblastic leukemia (ALL) arises in virtually all cases from B cell precursors that are arrested at pre-B cell receptor-dependent stages. The Philadelphia chromosome-positive (Ph(+)) subtype of ALL accounts for 25-30% of cases of adult ALL, has the most unfavorable clinical outcome among all ALL subtypes and is defined by the oncogenic BCR-ABL1 kinase and deletions of the IKAROS gene in ,80% of cases. Here, we demonstrate that the pre-B cell receptor functions as a tumor suppressor upstream of IKAROS through induction of cell cycle arrest in Ph(+) ALL cells. Pre-B cell receptor-mediated cell cycle arrest in Ph(+) ALL cells critically depends on IKAROS function, and is reversed by coexpression of the dominant-negative IKAROS splice variant IK6. IKAROS also promotes tumor suppression through cooperation with downstream molecules of the pre-B cell receptor signaling pathway, even if expression of the pre-B cell receptor itself is compromised. In this case, IKAROS redirects ...

However, limitations to the successful use of imatinib mesylate as a single agent include the problem of resistance, seen chiefly in patients with advanced-phase disease. This review summarizes the clinical results to date with imatinib mesylate and briefly discusses the problem of resistance before describing potential strategies, including the use ...

The added value of 2nd generation tyrosine kinase inhibitors (TKIs) is currently perhaps the most-discussed issue in chronic myeloid leukemia (CML) research and treatment. Therefore, with their recently published article "Second-generation tyrosine kinase inhibitors improve the survival of patients with chronic myeloid leukemia in whom imatinib therapy has failed", Ibrahim et al.1 focussed on an important topic. However, in our opinion, the methodological approach used in this paper is not always appropriate.. The choice of the historical control group treated with interferon-alfa seems not to be optimal. Even before the imatinib era, progress had been made in the treatment of CML as the results of the consecutive German studies and of the French CML-study group show.2-4 We doubt that the results of the 20-year old MRC trial represent an appropriate comparator group for the results achieved by the use of 2nd generation tyrosine kinase inhibitors. Furthermore, the authors use two different ...

Y1 - 2009/12/15. N2 - Gastrointestinal stromal tumors (GIST) are the most common type of sarcoma in the gastrointestinal tract. Surgery is the primary treatment modality, but many patients suffer disease recurrence or metastasis. Fortunately, the management of advanced GIST has been revolutionized by the use of small molecule kinase inhibitors that target the underlying pathogenetic mutant kinases found in the vast majority of cases. Approximately 85% of GISTs have oncogenic mutations in KIT, allowing for constitutive kinase activation that is responsible for cellular proliferation and survival. About 5 to 7% of GISTs have activating mutations of the homologous platelet-derived growth factor receptor alpha (PDGFRA) kinase. The progression-free and overall survival of patients with advanced disease is greatly ...

Chronic myelogenous leukemia (CML) is an uncommon type of cancer of the bone marrow - the spongy tissue inside bones where blood cells are made. CML causes an increased number of white blood cells in the blood.. The term "chronic" in chronic myelogenous leukemia indicates that this cancer tends to progress more slowly than acute forms of leukemia. The term "myelogenous" (my-uh-LOHJ-uh-nus) in chronic myelogenous leukemia refers to the type of cells affected by this cancer.. Chronic myelogenous leukemia can also be called chronic myeloid leukemia and chronic granulocytic leukemia. It typically affects older adults and rarely occurs in children, though it can occur at any age.. Advances in treatment have contributed to a greatly improved prognosis for people with chronic myelogenous leukemia. Most people will achieve remission and live for many years after diagnosis. ...

N2 - The anaerobic parasitic protozoa Tritrichomonas foetus is found incapable of de novo pyrimidine biosynthesis by its failure to incorporate bicarbonate, aspartate, or orotate into pyrimidine nucleotides or nucleic acids. Uracil phosphoribosyltransferase in the cytoplasm provides the major pyrimidine salvage for the parasite. Exogenous uridine and cytidine are mostly converted to uracil by uridine phosphorylase and cytidine deaminase in T. foetus prior to incorporation. T. foetus cannot incorporate labels from exogenous uracil or uridine into DNA; it has not detectable dihydrofolate reductase or thymidylate synthetase and is resistant to methotrexate, pyrimethamine, trimethoprim, and 5-bromovinyldeoxyuridine at millimolar concentrations.

This is the first reported case of perforation and haemorrhage of a Meckel's diverticulum leading to the incidental finding of a gastrointestinal stromal tumour within the diverticulum. Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract, however, when symptomatic, it is often misdiagnosed at presentation. Common complications presenting in adults include bleeding, obstruction, diverticulitis and perforation. Tumours within a Meckel's diverticulum are a rare but recognised complication. We discuss the management of a gastrointestinal tumour within the diverticulum. A 59-year-old Caucasian man presented with acute right iliac fossa pain with localized peritonism. At surgery, he was found to have a perforated and haemorrhagic Meckel's diverticulum, associated with a gastrointestinal stromal tumour within the apex of the diverticulum. The absence of necrosis and a low mitotic rate indicated primary resection with subsequent computed tomography surveillance to be

Gastrointestinal stromal tumor (GIST) is a rare malignancy of mesenchymal origin. The true incidence of GIST has historically been underestimated as these tumors were commonly misclassified as leiomyomas, leiomyosarcomas, and leiomyoblastomas.1 The term gastric stromal tumor was first proposed in 1983 to describe gastric wall tumors that lacked the ultrastructural features of smooth muscle cells and the immunohistochemical characteristics of Schwann cells.2 Mazur and Clark2 examined 28 gastric wall tumors that were originally classified by light microscopy as leiomyomas or leiomyosarcomas and, using electron microscopy, determined that some of these tumors lacked features expected in cells derived from smooth muscle. Additionally, using immunohistochemistry to identify the neuroectoderm marker S-100, they found that the majority of tumors failed to show evidence of a nerve sheath origin. They postulated that this subset of tumors that did not appear from a smooth muscle origin or peripheral ...

BACKGROUND: The cause of chronic myeloid leukemia (CML) is a constitutively active BCR-ABL tyrosine kinase. Imatinib inhibits this kinase, and in a short-term study was superior to interferon alfa plus cytarabine for newly diagnosed CML in the chronic phase. For 5 years, we followed patients with CML who received imatinib as initial therapy. METHODS: We randomly assigned 553 patients to receive imatinib and 553 to receive interferon alfa plus cytarabine and then evaluated them for overall and event-free survival; progression to accelerated-phase CML or blast crisis; hematologic, cytogenetic, and molecular responses; and adverse events. RESULTS: The median follow-up was 60 months. Kaplan-Meier estimates of cumulative best rates of complete cytogenetic response among patients receiving imatinib were 69% by 12 months and 87% by 60 months. An estimated 7% of patients progressed to accelerated-phase CML or blast crisis, and the estimated overall survival of patients who received imatinib as initial ...

PRIMARY OBJECTIVES:. I. To evaluate the safety, tolerability, and pharmacokinetic (PK) and pharmacodynamic (PD) profile of AMG 386 (trebananib) when administered alone and in combination with low-dose cytarabine in adult patients with: untreated AML considered ineligible for standard induction chemotherapy; refractory and/or relapsed AML following at least one cycle of prior therapy who are not currently eligible for stem cell transplantation.. SECONDARY OBJECTIVES:. I. To evaluate clinical responses in AML patients following AMG 386 therapy alone or in combination with low-dose cytarabine therapy.. II. To characterize the biological changes occurring in AML patients treated with AMG 386 alone or in combination with low-dose cytarabine, specifically: alteration in angiopoietin (Ang)1, Ang2, Tie2, vascular endothelial growth factor (VEGF), and VEGF receptor (VEGFR) expression; changes in bone marrow vascularization and hypoxia; changes in gene and/or micro ribonucleic acid (microRNA) expression; ...

ABCB1 polymorphism as prognostic factor in breast cancer patients treated with docetaxel and doxorubicin neoadjuvant chemotherapy. (2014). Among 216 patients, those with the 3435TT genotype had a longer overall survival than CC/CT. ABCB1 3435TT genotype had a higher blood concentration than CC/CT for docetaxel. These higher values in the C3435TT were associated with increased toxicities of neutropenia (low count of a type of white blood cell) and diarrhea. This study showed that the genetic polymorphism of ABCB1 C3435T might be associated with a longer overall survival. Our results also suggest that the prediction of docetaxel toxicity might be possible for C3435T polymorphism. Effect of polymorphisms within methotrexate pathway genes on methotrexate toxicity and plasma levels in adults with hematological malignancies. (2014). [1] Individuals respond differently to the cancer drug methotrexate (MTX) and experience differences in toxicity. The authors evaluated the impact of SNPs within the MTX ...

TREATMENT WITH LOW-DOSE CYTARABINE IN ELDERLY PATIENTS (AGE 70 YEARS OR OLDER) WITH ACUTE MYELOID LEUKEMIA: A SINGLE INSTITUTION EXPERIENCE

CML progresses gradually. It is often slow growing for many years. Eventually, it may transform itself into acute myelogenous leukemia (AML). This is a more aggressive type of leukemia. It progresses much more rapidly and is more serious.. Cancer occurs when cells in the body become abnormal. They divide without control or order. Leukemia is cancer of the white blood cells and their parent cells. Leukemia cells do not function normally. They cannot do what normal blood cells do. In this case they can not fight infections. This means that the person is more likely to become infected with viruses or bacteria. The cancerous cells also overgrow the bone marrow. This forces other normal components, like platelets out. Platelets are needed to help the blood clot. As a results people with leukemia may bleed more easily.. ...
