An intelligent non-invasive system for automated diagnosis of anemia exploiting a novel dataset.

Anemia is a condition in which the oxygen-carrying capacity of red blood cells is insufficient to meet the body's physiological needs. It affects billions of people worldwide. An early diagnosis of this disease could prevent the advancement of other disorders.

Neutrophil-to-Lymphocyte Ratio Is a Major Prognostic Factor in Non-small Cell Lung Carcinoma Patients Undergoing First Line Immunotherapy With Pembrolizumab.

Background/aim: Lung cancer is one of the most common malignant neoplastic diseases and by far the leading cause of cancer death worldwide. Recently, immune checkpoint inhibitors (ICIs) have received increasing attention for playing a crucial role in non-small cell lung cancer (NSCLC). Biomarkers, such as programmed cell death-ligand 1 (PD-L1) and tumor mutational burden (TMB), seemed to be helpful in selecting patients who are more likely to benefit from ICI treatment: however, their role has not yet been fully clarified.

Evaluation of prognostic histological parameters proposed for pleural mesothelioma in diffuse malignant peritoneal mesothelioma. A short report.

Introduction: Diffuse malignant peritoneal mesothelioma (DMPM) is a rare malignant neoplasm with poor survival that shares some similarities with the best-known pleural variant, pleural mesothelioma. The recent European Reference Network on Rare Adult Cancers (EURACAN)/International Association for the Study of Lung Cancer (IASLC) proposals attempted to improve the histological diagnosis and patient risk stratification. Herein, we investigated whether the pathology recommendations and suggestions of the pleural proposals were applicable to diffuse malignant peritoneal mesothelioma.

Integration of Lipidomics and Transcriptomics Reveals Reprogramming of the Lipid Metabolism and Composition in Clear Cell Renal Cell Carcinoma.

Clear cell renal cell carcinoma (ccRCC) is fundamentally a metabolic disease. Given the importance of lipids in many cellular processes, in this study we delineated a lipidomic profile of human ccRCC and integrated it with transcriptomic data to connect the variations in cancer lipid metabolism with gene expression changes. Untargeted lipidomic analysis was performed on 20 ccRCC and 20 paired normal tissues, using LC-MS and GC-MS.

Diffuse malignant peritoneal mesothelioma (DMPM) is a rare malignant neoplasm with a poor survival. Although some advances in knowledge have been obtained for the pleural form, much less is known about DMPM. Advantages in terms of prognosis are still limited and strong efforts need to be made.

Pancreatic Enzyme Replacement Therapy in Pancreatic Cancer.

Pancreatic cancer is an aggressive malignancy and the seventh leading cause of global cancer deaths in industrialised countries. More than 80% of patients suffer from significant weight loss at diagnosis and over time tend to develop severe cachexia. A major cause of weight loss is malnutrition.

Management of kidney cancer patients: 2018 guidelines of the Italian Medical Oncology Association (AIOM).

In the past two decades, the treatment landscape for patients with metastatic renal cell carcinoma has significantly changed thanks to the approval of several targeted molecular therapies (VEGF and mTOR inhibitors) and recently immune-checkpoint inhibitors. The Italian Association of Medical Oncology (AIOM) Renal Cell Cancer (RCC) Guidelines Panel has developed clinical guidelines to provide evidence-based information and recommendations to oncologists, urologists and all professionals involved in the management of patients with renal cell cancer.

Homotypic and Heterotypic Activation of the Notch Pathway in Multiple Myeloma-Enhanced Angiogenesis: A Novel Therapeutic Target?

Interactions of multiple myeloma (MM) cells with endothelial cells (ECs) enhance angiogenesis and MM progression. Here, we investigated the role of Notch signaling in the cross talk between ECs and MM cells enabling angiogenesis. MMECs showed higher expression of Jagged1/2 ligands, of activated Notch1/2 receptors, and of Hes1/Hey1 Notch target genes than ECs from monoclonal gammopathy of undetermined significance patients, suggesting that homotypic activation of Notch pathway occurs in MM.

Genomic changes of chromosomes 8p23.1 and 1q21: Novel mutations in malignant mesothelioma.

Introduction: Malignant mesothelioma is an aggressive malignancy of the thoracic cavity caused by prior asbestos exposure. In the peritoneum the mesothelioma is an extremely rare condition. In the present preliminary study, high-resolution array-comparative genomic hybridization (a-CGH) was performed to identify genetic imbalances in a series of malignant peritoneal mesothelioma cases.

Early tumor regrowth is a contributor to impaired survival in patients with completely resected advanced ovarian cancer. An exploratory analysis of the Intergroup trial AGO-OVAR 12.

Objective: Surgical assessment of residual tumor provides the strongest prognostic information in advanced ovarian cancer (AOC), with the best outcome observed after complete resection. Postoperative radiological assessment before initiation of chemotherapy can supplement the information obtained by surgical assessment; however, it may also reveal conflicting findings.

Methods: Patients with AOC enrolled in the AGO-OVAR 12 trial underwent baseline imaging before the first chemotherapy cycle.

Survival in clinical stage I endometrial cancer with single vs. multiple positive pelvic nodes: results of a multi-institutional Italian study.

Objective: To investigate survival outcomes in endometrioid endometrial cancer (EEC) patients with single vs. multiple positive pelvic lymph nodes.

Methods: We performed a retrospective evaluation of all consecutive patients with histologically proven International Federation of Gynecology and Obstetrics (FIGO) stage IIIC1 EEC who underwent primary surgical treatment between 2004 and 2014 at seven Italian gynecologic oncology referral centers.

The chick embryo chorioallantoic membrane as an in vivo experimental model to study human neuroblastoma.

The chick embryo chorioallantoic membrane (CAM) has long been a favored system for the study of tumor angiogenesis because at the stage of development when generally tumor grafts are placed (6-10 days of incubation), the chick's immunocompetent system is not fully developed and the conditions for rejection have not yet been established. All studies for mammalian neoplasms, including neuroblastoma, have used tumor cell lines, tumor bioptic specimens, cell suspensions derived from tumors, and mouse tumor xenografts bioptic specimens. CAM can also be used to study the effects of antiangiogenic molecules on tumor cell suspensions of tumor bioptic specimens.

A revisited concept. Tumors: Wounds that do not heal.

In 1986, Harold F. Dvorak, Professor of Pathology at Harvard Medical School Boston, published an essay in the New England Journal of Medicine entitled "Tumors: Wounds that do not heal" pointed out that similarities exist between tumor stroma generation and wound healing. Cancers share many features in common with tissue regeneration, including immune response, cell proliferation, cell migration, tissue remodeling, and cell death.

The use of the chick embryo chorioallantoic membrane as experimental model to study virus growth and to test the clonal selection hypothesis. The contribution of Sir Mac Farlane Burnet.

Sir Mac Farlane Burnet was the most honored of all Australian scientists. In 1960, Burnet shared the Nobel Prize for Medicine with Peter Medawar of Britain for the discovery of acquired immunological tolerance. He developed techniques for growing influenza viruses in the chorioallantoic membrane of the chick embryo.

Bcl6/p53 expression, macrophages/mast cells infiltration and microvascular density in invasive breast carcinoma.

To better understand the breast cancer progression and therapeutic resistance is crucial deepen the molecular mechanisms related to regulation of cells behavior in the tumor microenvironment. Inappropriate expression or activation of transcription factors in tumor breast microenvironment can lead to the malignant behavior of breast cancer cells. Bcl6 is a transcriptional factor that may play a role in the pathogenesis of breast cancer.

The role of the epithelial-to-mesenchymal transition (EMT) in diseases of the salivary glands.

The link between inflammatory microenvironment and cancer emerged in the last years as a decisive factor in the induction of the pathological epithelial-mesenchymal transition (EMT). The EMT induces changes of cell states converting the epithelial cells to mesenchymal cells when this program is fully executed and EMT has emerged as a central driver of tumor malignancy. Cellular pathways activated by chronic inflammation brought about by chronic infections, by immune-mediated diseases, or by dysregulated wound healing at sites of repetitive tissue injury, constitute risk factors or initial cell transformation and for cancer progression.

Historical overview of lymphangiogenesis.

The investigation of the lymphatic system has a very long and intriguing history, with several medical figures which brought important contributions. Work on the lymphatic system began in the 17th century, and by the beginning of the 19th century the anatomy of most of the lymphatic system had been described. This system is an essential component of the immune system, as well as vital to the maintenance of fluid homeostasis within the body.

Consensus guidelines for the use and interpretation of angiogenesis assays.

The formation of new blood vessels, or angiogenesis, is a complex process that plays important roles in growth and development, tissue and organ regeneration, as well as numerous pathological conditions. Angiogenesis undergoes multiple discrete steps that can be individually evaluated and quantified by a large number of bioassays. These independent assessments hold advantages but also have limitations.

Inhibition of mTOR complex 2 restrains tumor angiogenesis in multiple myeloma.

The mammalian Target of Rapamycin (mTOR) is an intracellular serine/threonine kinase that mediates intracellular metabolism, cell survival and actin rearrangement. mTOR is made of two independent complexes, mTORC1 and mTORC2, activated by the scaffold proteins RAPTOR and RICTOR, respectively. The activation of mTORC1 triggers protein synthesis and autophagy inhibition, while mTORC2 activation promotes progression, survival, actin reorganization, and drug resistance through AKT hyper-phosphorylation on Ser473.

Rhu-Epo down-regulates pro-tumorigenic activity of cancer-associated fibroblasts in multiple myeloma.

We have previously demonstrated that recombinant human erythropoietin (rHuEpo) is involved in the regulation of the angiogenic response in multiple myeloma (MM) through a direct effect on macrophages and endothelial cells isolated from the bone marrow of patients with MM. The aim of the present study was designed to determine the effects of rHuEpo on cancer-associated fibroblasts (CAFs) from monoclonal gammopathy of undetermined significance (MGUS) and MM patients by means of in vitro and in vivo assays. rHuEpo treatment reduces the expression of mRNA levels of fibroblast activation markers, namely alpha smooth actin (αSMA) and fibroblast activation protein (FAP) in MGUS and MM CAFs, and of pro-inflammatory and pro-angiogenic cytokines, including interleukin (IL)-6 and IL-8, vascular endothelial growth factor-A (VEGF-A), fibroblast growth factor-2 (FGF-2), and hepatocyte growth factor (HGF) in MM CAFs.

Laparoscopic surgery in the treatment of stage I adult granulosa cells tumors of the ovary: Results from the MITO-9 study.

Objective: Surgery represents the mainstay of treatment of stage I adult type granulosa cell tumors of the ovary (AGCTs). Because of the rarity and indolent course of the disease, no prospective trials are available. Open surgery has long been considered the traditional approach; oncological safety of laparoscopy is only supported by small series or case reports.

Targeting angiogenesis in multiple myeloma by the VEGF and HGF blocking DARPin protein MP0250: a preclinical study.

The investigational drug MP0250 is a multi-specific DARPin molecule that simultaneously binds and neutralizes VEGF and HGF with high specificity and affinity. Here we studied the antiangiogenic effects of the MP0250 in multiple myeloma (MM). In endothelial cells (EC) isolated from bone marrow (BM) of MM patients (MMEC) MP0250 reduces VEGFR2 and cMet phosphorylation and affects their downstream signaling cascades.

A new role of mast cells in arteriogenesis.

Arteriogenesis is defined as the growth of functional collateral arteries from pre-existing arterio-arteriolar anastomoses. The role of mast cells in arteriogenesis is largely unexplored. Recent evidences suggest that mast cells together with other inflammatory cells, including monocytes-macrophages, lymphocytes, NK cells and endothelial precursor cells (EPCs) may be involved in this process.

Mast cells and angiogenesis in pancreatic ductal adenocarcinoma.

Mast cells are recognized as critical components of the tumor stromal microenvironment in several solid and hematological malignancies, promoting angiogenesis and tumor growth. A correlation between mast cells infiltration, angiogenesis and tumor progression has been reported for pancreatic ductal adenocarcinoma as well. Mast cells contribute to the aggressiveness of the pancreatic ductal carcinoma enhancing the expression of several pro-angiogenic factors such as vascular endothelial growth factor, fibroblast growth factor-2, platelet-derived growth factor and angiopoietin-1 as well as stimulating the pancreatic cancer cells proliferation by IL-13 and tryptase.
