Deferasirox drives ROS-mediated differentiation and induces interferon-stimulated gene expression in human healthy haematopoietic stem/progenitor cells and in leukemia cells.

Background: Administration of the iron chelator deferasirox (DFX) in transfusion-dependent patients occasionally results in haematopoiesis recovery by a mechanism remaining elusive. This study aimed to investigate at a molecular level a general mechanism underlying DFX beneficial effects on haematopoiesis, both in healthy and pathological conditions.

Methods: Human healthy haematopoietic stem/progenitor cells (HS/PCs) and three leukemia cell lines were treated with DFX.

Is there a role for immunotherapy in malignant pleural mesothelioma?

Malignant pleural mesothelioma (MPM) is a very aggressive malignancy, mainly caused by asbestos exposure. Patients with MPM have a poor prognosis that remained substantially unchanged in the last few years and limited effective therapeutic options with no recognized second or further-line therapy. In this context, also in view of the positive results observed in other tumor types, immunotherapy could play a relevant role.

Real life experience with frontline azacitidine in a large series of older adults with acute myeloid leukemia stratified by MRC/LRF score: results from the expanded international E-ALMA series (E-ALMA+).

Azacitidine (AZA) prolonged overall survival (OS) in the AZA-AML-001 trial. However, few subjects were randomized to AZA or intensive chemotherapy (IC). The Medical Research Council (MRC) and the Leukemia Research Foundation (LRF) developed a score for older AML patients receiving IC or non-intensive regimens, whereas the E-ALMA study validated a score for survival and response in elderly patients receiving AZA in daily practice.

Progress and challenges in the treatment of small cell lung cancer.

Small cell lung cancer (SCLC) is a very aggressive malignancy characterized by high cellular proliferation and early metastatic spread. In fact, although SCLC is a chemosensitive and radiosensitive disease, the initial responsiveness to chemotherapy is usually followed by development of resistance and the prognosis remains poor with a median survival of less than 12 months in patients with extensive disease (ED-SCLC). Furthermore, no significant progress has been made over the last years, with no newly approved drug.

Genetic interaction of P2X7 receptor and VEGFR-2 polymorphisms identifies a favorable prognostic profile in prostate cancer patients.

VEGFR-2 and P2X7 receptor (P2X7R) have been described to stimulate the angiogenesis and inflammatory processes of prostate cancer. The present study has been performed to investigate the genetic interactions among VEGFR-2 and P2X7R SNPs and their correlation with overall survival (OS) in a population of metastatic prostate cancer patients. Analyses were performed on germline DNA obtained from blood samples and SNPs were investigated by real-time PCR technique.

Dietary glycemic load and risk of cognitive impairment in women: findings from the EPIC-Naples cohort.

Cognitive impairment is a common cause of morbidity in the elderly. The relationship between dietary habits and cognitive impairment in a female population living in the metropolitan area of Naples, in the Mediterranean part of Italy, has been evaluated in the Naples EPIC prospective cohort study. The study cohort, enrolled between 1993 and 1997, is composed of 5062 women aged 30-69 years.
