: Disease overview:Systemic mastocytosis (SM) results from a clonal proliferation of abnormal mast cells (MC) in one or more extra-cutaneous organs. DIAGNOSIS: The major criterion is presence of multifocal clusters of morphologically abnormal MC in the bone marrow. Minor diagnostic criteria include elevated serum tryptase level, abnormal MC expression of CD25 and/or CD2, and presence of KITD816V. Risk stratification: The 2008 World Health Organization (WHO) classification of SM has been shown to be prognostically relevant...

OBJECTIVE: To evaluate the outcome of patients treated with second-line chemotherapy for methotrexate-resistant low-risk GTN at the Sheffield Centre, UK between 2001 and 2015, including the novel use of single-agent carboplatin as a strategy to reduce exposure to combination chemotherapy. METHODS: 392 low-risk GTN patients were treated with first-line methotrexate. The selection of chemotherapy regimen following methotrexate-resistance depended on the volume of residual disease as indicated by the serum hCG value at the time, with patients switching to either single-agent dactinomycin at an hCG level<150IU/L from 2001-2010 and <300IU/L since 2010, or to combination treatment with etoposide/dactinomycin (EA) above these thresholds...

Inhibitors of the B cell receptor (BCR) represent an attractive therapeutic option for patients with chronic lymphocytic leukemia. Recently approved inhibitors of Bruton's tyrosine kinase (ibrutinib) and phosphatidylinositol 3-kinase (idelalisib), are promising agents because they are generally well tolerated and highly effective. These agents may be particularly important in the treatment of older patients who are less able to tolerate the myelosuppression (and infections) associated with chemoimmunotherapy...

OBJECTIVE Glioblastoma (GBM) is a highly aggressive malignancy that requires a multidisciplinary therapeutic approach of surgery, chemotherapy, and radiation therapy, but therapy is frequently limited by side effects. The most common adverse effect of chemotherapy with temozolomide (TMZ) is myelosuppression. It remains unclear whether the degree of bone-marrow suppression might serve as a biomarker for treatment outcome. The aim of the current study was to investigate whether the degree of bone-marrow toxicity in patients treated with TMZ correlates with overall survival (OS) and MRI-based time to progression (progression-free survival [PFS])...

BACKGROUND: Gemcitabine is currently the standard chemotherapy for the adjuvant treatment of pancreatic cancer. This chemotherapeutic agent is generally well-tolerated, myelosuppression and gastrointestinal toxicity being common side effects. Nevertheless, gemcitabine-induced pulmonary toxicity has been rarely reported. Despite its low incidence, the spectrum of pulmonary injury is wide, including potentially fatal conditions. We report a case of acute interstitial pneumonia related to gemcitabine, completely solved with Imatinib Mesylate (IM)...

PURPOSE: Docetaxel is used to treat many cancers, and neutropenia is the dose-limiting factor for its clinical use. A population pharmacokinetic-pharmacodynamic (PK-PD) model was introduced to predict the development of docetaxel-induced neutropenia in Japanese patients with non-small cell lung cancer (NSCLC). METHODS: Forty-seven advanced or recurrent Japanese patients with NSCLC were enrolled. Patients received 50 or 60 mg/m(2) docetaxel as monotherapy, and blood samples for a PK analysis were collected up to 24 h after its infusion...

The recent rise in the use of linezolid to treat a variety of resistant pathogens has uncovered many side effects. Some patients develop lactic acidosis, myelosuppression, optic or peripheral neuropathies, and myopathies. We evaluated an elderly patient who presented to the Emergency Room with linezolid toxicity and a novel neurologic complication characterized by bilateral globi pallidi necrosis. Mitochondrial ribosome inhibition was described to be the predisposing factor. The patient belongs to the mitochondrial J1 haplotype known to be associated with side effects of the drug...

Central clonal deletion has been considered the critical factor responsible for the robust state of tolerance achieved by chimerism-based experimental protocols, but split-tolerance models and the clinical experience are calling this assumption into question. Although clone-size reduction through deletion has been shown to be universally required for achieving allotolerance, it remains undetermined whether it is sufficient by itself. Therapeutic Treg treatment induces chimerism and tolerance in a stringent murine BM transplantation model devoid of myelosuppressive recipient treatment...

BACKGROUND: Nanoparticle albumin-bound paclitaxel (nab-paclitaxel) and nedaplatin (NDP) are used for the treatment of patients with cervical cancer. However, to the authors' knowledge, the use of this combination regimen among patients with advanced, recurrent, or metastatic cervical cancer has rarely been reported. METHODS: Patients with pathologically confirmed, stage IVB (FIGO staging 2009), recurrent or metastatic cervical cancer were eligible. Nab-paclitaxel at a dose of 175 mg/m(2) plus NDP at a dose of 80 mg/m(2) was administered intravenously every 3 weeks...

UNLABELLED: Today due to improvements in cancer treatment there is an increasing number of long-term cancer survivors, many of whom suffer from infertility caused by malignancy itself and chemo- or radiotherapy. Also, anticancer therapy may cause myelosuppression. Presently granulocyte colony stimulating factor (G-CSF) is used for prevention and treatment of myelosuppression. Another treatment option used to decrease intoxication and ameliorate side effects of cancer therapy is sorption technology...

Myelofibrosis is a BCR-ABL-negative myeloproliferative neoplasm characterized by abnormal hematopoiesis. Alterations to the Janus kinase-signal transducer and activator of transcription pathway result in dysregulation of gene transcription and cell proliferation. Patients with symptomatic myelofibrosis present with a variety of signs and symptoms including, but not limited to myelosuppression, marked splenomegaly, abdominal discomfort, fatigue, and blood transfusion-dependence. Traditional myelosuppressive therapies including hydroxyurea, azacitidine, and cladribine aim to reduce constitutional symptoms and control the burden of disease...

Linezolid (LZD), severed as the first oxazolidinone antibiotic, was active against multidrug-resistant gram-positive strains. LZD can induce thrombocytopenia, anemia and leukocytopenia. Currently, reports on pure red cell aplasia (PRCA) cases induced by LZD are relatively rare (4-7). In this paper, we reported a patient with PRCA twice induced by LZD. A 37-year-old man was diagnosed with myelodysplatic syndrome (MDS) and underwent allo-HSCT from an unrelated donor with ABO blood type and leukocyte antigen (HLA)-matching...

Myelosuppression is the most common dose-limiting adverse effect of chemotherapies. In the present study, we investigated the involvement of nuclear erythroid 2-related factor 2 (Nrf2) in cyclophosphamide-induced myelosuppression in mice, and evaluated the potential of activating Nrf2 signaling as a preventive strategy. The whole blood from Nrf2(-/-) mice exhibited decreased antioxidant capacities, while the bone marrow cells, peripheral blood mononuclear cells and granulocytes from Nrf2(-/-) mice were more susceptible to acrolein-induced cytotoxicity than those from wild type mice...
