Objectives: Psychosocial interventions that mitigate psychosocial distress in cancer patients are important. The primary aim of this study was to examine the feasibility and acceptability of an adaptation of the Mindful Self-Compassion (MSC) program among adult cancer patients. A secondary aim was to examine pre-post-program changes in psychosocial wellbeing.

We analyzed 28 patients with PMBL treated with chemotherapy, of whom 25 (89%) also received rituximab and 17 (61%) radiotherapy. PET-CT scans were interpreted using visual analysis and a 5-point scale.

We sought to determine the utility of surveillance positron emission tomography-computed tomography (PET-CT) in patients with TrIL achieving complete metabolic remission (CMR) after primary therapy. We performed a retrospective analysis of patients with TrIL treated at Peter MacCallum Cancer Centre between 2002 and 2012 who achieved CMR after primary therapy who had ≥1 subsequent surveillance PET-CT.

However, sometimes unexpectedly poor CD34(+) cell yields are obtained. To determine the effect, if any, of a range of factors on the ability of the PB CD34(+) count to predict collection CD34(+) cell count, we performed a retrospective analysis on consecutive hematopoietic progenitor cell apheresis collections between 2004 and 2008.

The review then looks at the mobilisation of mesenchymal stromal cells, immune cells as well as malignant cells and what clinical implications there are.

Mobilization is most commonly performed with recombinant human G-CSF with or without chemotherapy, but a proportion of patients/donors fail to mobilize sufficient cells. BM disease, prior treatment, and age are factors influencing mobilization, but genetics also contributes.

Recombinant human cytokines have been the mainstay of therapeutic HSPC mobilization, particularly G-CSF. Even with currently used mobilization regimens using G-CSF with or without chemotherapy, up to 60% of patients can fail to mobilize enough HSPC for a transplant procedure.

We have previously identified a serine residue (Ser585) in the betac subunit of the granulocyte-macrophage colony-stimulating factor receptor that selectively and independently promotes cell survival. We now show that Ser585 phosphorylation is constitutive in 20 (87%) of 23 acute myeloid leukemia (AML) patient samples, indicating that this survival-only pathway is frequently deregulated in leukemia.

Data is lacking regarding risk factors for CNS relapse, and for those patients in whom CNS prophylaxis could be beneficial. We present single institution retrospective analysis of data of baseline features, clinical course, rate of CNS disease and putative risk factors in 62 patients with MCL (18 female, 44 male).
View Article and Find Full Text PDFThe recent explosion in the understanding of the cellular and molecular mechanisms underlying hematopoietic stem and progenitor cell (HSPC) mobilization has facilitated development of novel therapeutic agents, targeted at improving mobilization kinetics as well as HSPC yield. With the development of new agents comes the challenge of choosing efficient and relevant preclinical studies for the testing of the HSPC mobilization efficacy of these agents. This article reviews the use of the mouse as a convenient small animal model of HSPC mobilization and transplantation, and outlines the range of murine assays that can be applied to assess novel HSPC mobilizing agents.

Since bone marrow (BM) neutrophils play a central role in HSPC mobilization, we hypothesized that granulocyte colony-stimulating factor (G-CSF)-mediated mobilization would be enhanced by further expanding the size of the BM granulocyte pool.
Methods: We tested the potential of the retinoic acid receptor alpha (RARalpha) specific agonist VTP195183, and the pan-RAR agonist all-trans retinoic acid (ATRA), to enhance G-CSF-mediated mobilization of HSPC, in two mouse strains.
Opportunistic infection with invasive aspergillosis (IA) is increasingly frequent in immunocompromised patients, particularly in those with hematological malignancies. In this setting, IA typically involves the lung, with extra-pulmonary involvement usually occurring in the setting of disseminated infection. We report a case of localized gastrointestinal IA complicating induction chemotherapy for acute myeloid leukemia (AML).

We present the case of a 65-yr-old man who was successfully treated with alemtuzumab monotherapy for both disorders, but at a cost of severe infectious morbidity and prolonged pancytopenia.
