Purpose There is a growing demand for BRCA1/ 2 mutation ( BRCAm) testing in patients with ovarian cancer; however, the limited number of genetic counselors presents a potential barrier. To facilitate more widespread BRCAm testing in ovarian cancer, pretest counseling by the oncology team could shorten testing turnaround times and ease the pressure on genetic counselors. Patients and Methods The prospective, observational Evaluating a Streamlined Onco-genetic BRCA Testing and Counseling Model Among Patients With Ovarian Cancer (ENGAGE) study evaluated a streamlined, oncologist-led BRCAm testing pathway...

Colorectal cancer is one of the most common malignancies. Aberrant expressed microRNAs (miRNAs) have been demonstrated to have strong associations with colorectal cancer by repressing their targets. Therefore, miRNAs are thought to have significant promise in the diagnosis and prognosis of colorectal cancer. Previous studies indicated that miR-155 and collagen triple helix repeat containing 1 (CTHRC1) were both involved in pathogenesis of colorectal cancer, but the underlying mechanisms of miR-155 and CTHRC1 are still unknown...

Melanoma is an aggressive skin cancer; an early detection of the primary tumor may improve its prognosis. Despite many genes have been shown to be involved in melanoma, the full framework of melanoma transformation has not been completely explored. The characterization of pathways involved in tumor restraint in in vitro models may help to identify oncotarget genes. We therefore aimed to probe novel oncotargets through an integrated approach involving proteomic, gene expression and bioinformatic analysis We investigated molecular modulations in melanoma cells treated with ascorbic acid, which is known to inhibit cancer growth at high concentrations...

BACKGROUND: Acute respiratory failure (ARF) is the leading reason for intensive care unit (ICU) admission in immunocompromised patients. High-flow nasal oxygen (HFNO) therapy is an alternative to standard oxygen. By providing warmed and humidified gas, HFNO allows the delivery of higher flow rates via nasal cannula devices, with FiO2 values of nearly 100%. Benefits include alleviation of dyspnea and discomfort, decreased respiratory distress and decreased mortality in unselected patients with acute hypoxemic respiratory failure...

Here we present the application of deep neural network (DNN) ensembles trained on transcriptomic data to identify the novel markers associated with the mammalian embryonic-fetal transition (EFT). Molecular markers of this process could provide important insights into regulatory mechanisms of normal development, epimorphic tissue regeneration and cancer. Subsequent analysis of the most significant genes behind the DNNs classifier on an independent dataset of adult-derived and human embryonic stem cell (hESC)-derived progenitor cell lines led to the identification of COX7A1 gene as a potential EFT marker...

Platelet transfusion in patients, particularly in onco-haematology, is frequent and can become chronic in some cases. Post-transfusion alloimmunization is often seen, in practice. The risk of this is significantly improved in multitransfused patients. Several classes of antigens binding on platelets (HLA and HPA) are involved and also red blood cell antigens (residual red blood cells in platelet concentrates). Platelet alloimmunization causes a poor transfusion response, refractoriness and, more rarely, post-transfusion purpura...

In the era of evidence-based medicine, clinicians aim to establish standards of care from randomized studies. Following, personalized medicine has emerged, as new individualized biomarkers could help to predict sensitivity to specific treatment. In this paper, we show that, for diffuse low-grade glioma, some specificities - dual goal of both survival and functional gain, long duration of the disease with multistep treatments, multiparametric evaluation of the onco-functional balance of each treatment modality - call for a change of paradigm...

Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignant diseases worldwide. It is refractory to conventional treatments, and consequently has a documented 5-year survival rate as low as 7%. Increasing evidence indicates that activated pancreatic stellate cells (PSCs), one of the stromal components in tumor microenvironment (TME), play a crucial part in the desmoplasia, carcinogenesis, aggressiveness, metastasis associated with PDAC. Despite the current understanding of PSCs as a "partner in crime" to PDAC, detailed regulatory roles of PSCs and related microenvironment remain obscure...

Carcinoma-associated fibroblasts (CAFs) play a key onco-supportive role during prostate cancer (PCa) development and progression. We previously reported that the reactive oxygen species (ROS)-producing enzyme NADPH oxidase 4 (Nox4) is essential for TGFβ1-mediated activation of primary prostate human fibroblasts to a CAF-like phenotype. This study aimed to further investigate the functional relevance of prostatic Nox4 and determine whether pharmacological inhibition of stromal Nox4 abrogates paracrine-mediated PCa-relevant processes...

OBJECTIVES: Definitive diagnosis of invasive candidiasis (IC) may be difficult to achieve in patients with haematological malignancy (PHM). We aimed to evaluate the performance of BDG for the diagnosis and the follow-up of IC in PHM. PATIENTS AND METHODS: We retrospectively reviewed the serological data of BDG assay in adult and paediatric PHM, who developed candidemia or chronic disseminated candidiasis (CDC) through a 4-year period. Sensitivity and kinetics of BDG were determined for both clinical forms...

Malignant transformation of cells is often accompanied by the loss of the primary cilium, a protruding microtubule-based sensory organelle, suggesting that it plays an "onco-suppressive" role. Therefore, restoration of the primary cilium is being explored as a new therapeutic approach to attenuate tumor growth. Recently, several commonly used chemotherapeutic drugs have been identified to induce the primary cilium in pancreatic cancer cells. The mechanisms by which these drugs re-express the cilium remain, however, enigmatic...

Background: Although oncologic testicular sperm extraction (onco-TESE) has been increasingly practiced, the evidence of onco-TESE performed in patients with testicular cancer is insufficient. Furthermore, in bilateral testicular cancer, accounting for 0.5%-1% of testicular cancers, onco-TESE is more challenging and has been insufficiently reported. Case presentation: Here we report the case of a 25-year-old man who underwent onco-TESE from his residual single testis with a nonseminomatous germ cell tumor that occurred 5 years after orchiectomy of the contralateral testis...

BACKGROUND: Renal complications are a relevant clinical issue in patients with cancer; conversely, cancer in patients affected by kidney diseases is a growing problem mainly due to the aging of the general population. Onco-Nephrology is a novel subspecialty addressing these issues. SUMMARY: Acute kidney injury (AKI) is an important cause of morbidity and mortality in cancer patients, and recognizes a number of different causes, which can impact, directly and indirectly, on kidney function...

The effectiveness of chemotherapy is largely limited by drug resistance. In the past few decades, modulation of anticancer drug resistance plays little role in benefit of clinical outcomes due to complex drug resistance mechanisms. Mitophagy, an important mitochondrial quality control system, selectively degrades excessive or damaged mitochondria by autophagy. Accumulating reports are suggesting that dysregulation of mitophagy contributes to neoplastic progression and drug resistance in various types of tumors...

Depending on the function of their target genes, microRNAs (miRNAs) act as either tumor suppressors or oncogenes. Therefore, miRNAs represent a novel therapeutic strategy for prevention and management of cancer by targeting of onco-miRNAs or mimicking of tumor suppressor miRNAs. Herein, we identified novel tumor suppressor miRNAs and investigated their molecular mechanisms. To identify novel tumor suppressor miRNAs, we used 532 human miRNA mimic libraries and measured cell viability using MTS assays. The function of miR-4779 was then analyzed using cell cycle analyses and apoptosis, colony forming, and soft agar assays...

In Japan, cardiovascular diseases are frequent complications in cancer patients owing to the rapidly aging population and changes in the overall lifestyle. In addition, new anticancer therapies have substantially improved the prognosis of cancer patients. Cardiotoxicity, also referred to as cancer treatment-related cardiac dysfunction, has become an important cause of morbidity and mortality in cancer patients. Cardiotoxicity may consist of hypertension, arrhythmia, thromboembolism, coronary artery disease, valvular disease, and left ventricular dysfunction which may progress to heart failure...

Cancer and cardiovascular disease are 2 major disease of the Japanese cause of death. Both patients with cancer complicated with cardiovascular disease and patients with cancer developing cardiovascular disorder during cancer therapyare increasing recently. Because aging is the onset risk factor, as for these, it is predicted that the patients with both cancer and cardiovascular disease increase more and more by the arrival of the aging society. Recently, the new research field called cardiooncology( or onco-cardiology)has been established, and the cooperation of medical oncologist and cardiologist becomes indispensable...
