Nutrition in oncologic patients during antiblastic treatment.

Cancer may induce weight loss and cachexia, and cancer treatment may contribute to nutritional impairment. Here, we review the literature on the mechanisms of cancer cachexia and the pharmacological interventions both in use in clinical practice and currently under development. Based on this analysis, several nutritional proposals for cancer patients are suggested and the importance of good nutritional status in candidates for hematopoietic stem cell transplantation is highlighted

Surface-antigen expression profiling of B cell chronic lymphocytic leukemia: from the signature of specific disease subsets to the identification of markers with prognostic relevance

Studies of gene expression profiling have been successfully used for the identification of molecules to be employed as potential prognosticators. In analogy with gene expression profiling, we have recently proposed a novel method to identify the immunophenotypic signature of B-cell chronic lymphocytic leukemia subsets with different prognosis, named surface-antigen expression profiling. According to this approach, surface marker expression data can be analysed by data mining tools identical to those employed in gene expression profiling studies, including unsupervised and supervised algorithms, with the aim of identifying the immunophenotypic signature of B-cell chronic lymphocytic leukemia subsets with different prognosis. Here we provide an overview of the overall strategy employed for the development of such an "outcome class-predictor" based on surface-antigen expression signatures. In addition, we will also discuss how to transfer the obtained information into the routine clinical practice by providing a flow-chart indicating how to select the most relevant antigens and build-up a prognostic scoring system by weighing each antigen according to its predictive power. Although referred to B-cell chronic lymphocytic leukemia, the methodology discussed here can be also useful in the study of diseases other than B-cell chronic lymphocytic leukemia, when the purpose is to identify novel prognostic determinants

Primary Non-Hodgkin\u2bcs Lymphoma of the Vulva

The aim of this study was to add a new case of primary non-Hodgkin's malignant lymphoma of the vulva to the literature and to review the current literature.We searched the PubMed/MEDLINE databases for previous case reports using the key words "non-Hodgkin's malignant lymphoma of the vulva,'' "vulvar lymphoma,'' and "primary vulvar non-Hodgkin's lymphoma.'' We found 29 cases of primary vulvar non-Hodgkin's malignant lymphoma of the vulva reported until 2015. Among them, only 8 cases of diffuse large B-cell lymphoma (DLBCL), classified according to the most recent 2008 WHO classification, were reported.Moreover, only few studies reported the therapeutic management and clinical follow-up of patients affected by this condition.Due to its uncommon presentation, the primary non-Hodgkin's malignant lymphoma of the vulva can be undiagnosed; thus gynecologists, oncologists, and pathologists should be aware of this condition, as a correct diagnosis is essential for an appropriate therapeutic management

miR-335-laden B Cell-Derived Extracellular Vesicles Promote SOX4-Dependent Apoptosis in Human Multiple Myeloma Cells

Multiple myeloma (MM) is characterized by the accumulation of malignant plasma cells in the bone marrow. Despite novel therapies, MM still remains an incurable cancer and new strategies are needed. Increased expression of the transcription factor Sex-determining region Y-related high-mobility-group box transcription factor 4 (SOX4) has been correlated with tumor development and progression through a variety of distinct processes, including inhibition of apoptosis, increased cell invasion and metastasis, and induction and maintenance of cancer-initiating cells. The role of SOX4 in MM is largely unknown. Since SOX4 is a known target of miR-335, we used miR-335 to assess whether SOX4 modulation could promote apoptosis in MM cells. Using an MM cell model we show that miR-335 acts both on SOX4-related genes (AKT, PI3K) and hypoxia-inducible factor 1-alpha (Hif1-α). In addition, we show miR-335-laden extracellular vesicles induced in B cells (iEVs) are also effective in targeting SOX4, causing apoptosis. Collectively, we propose that miR-335-laden iEVs could be developed as a novel form of gene therapy in MM
