Filter by:45 individuals were subdivided into 3 groups, 15 patients with oral premalignant lesions, 15 patients with oral malignant lesions and 15 control individuals. Levels of chemerin and MMP-9 were evaluated in serum and saliva of these subjects utilizing the ELISA technique.
Phase 1 Part (Complete): Open-label, sequential dose escalation study of pelabresib in patients with previously treated Acute Leukemia, Myelodysplastic Syndrome, Myelodysplastic/Myeloproliferative Neoplasms, and Myelofibrosis. Phase 2 Part: Open-label study of CPI-0610 with and without Ruxolitinib in patients with Myelofibrosis. CPI-0610 is a small molecule inhibitor of bromodomain and extra-terminal (BET) proteins.
The objective of this study is to determine whether we can use minimally invasive techniques to gain access to exfoliated ductal epithelial cells for whole genome sequencing. 1. To examine women with nipple aspiration, ductoscopy and ductal lavage and collect exfoliated cells from two ducts per woman. 2. To collect a blood sample at the time of the examination in order to obtain the woman's baseline genomic sequence. 3. De-identified samples will then have DNA and RNA extracted and whole genome sequencing and transcriptome analysis performed by Covance and Illumina. 4. Comparisons will be made within a breast (two ducts) and between the duct and blood as well as between women.
Epithelial Ovarian cancer (EOC) is the leading cause of death among gynaecologic malignancies in western civilized countries, with an estimated prevalence in Europe and the US of 752,600 in 2007 and 59,828 deaths annually. State-of-the-art diagnostic tests for EOC include transvaginal ultrasonography and serum cancer antigen (CA-125) measurements; the specificity of these diagnostic tools however is low, and both tests are not effective enough at detecting EOC early enough to improve clinical outcomes. Definitive diagnosis of EOC still relies on histological or cytological confirmation. These findings underline the importance for an effective test for early detection of EOC. In the current project we will obtain a lavage of the uterine cavity. It will be investigated whether cells from EOCs or genetic material from those cells can be detected in the lavage fluid. Aim of this study: There is a clear clinical need for a diagnosis test to detect EOC at an earlier stage.
Single operater pancreatico-cholangioscopy is performed through the working channel of conventional duodenoscopes. A visual evaluation of the biliary and pancreatic ductal systems is completed and obvious or suspicious macroscopic lesions are targeted by biopsy forceps. Evaluation of the usefulness of probe based confocal laser endomicroscopy in the evaluation of suspected premalignant lesions in the biliary duct and in the pancreas.
This pilot research trial studies factors affecting patient participation in Acquired Immune Deficiency Syndrome (AIDS) Malignancy Clinical Trials Consortium clinical trials. Determining how patients makes decisions about participating in a clinical trial may help doctors plan clinical trials in which more patients are willing to participate and are satisfied with their decision to participate.
In industrialized countries, cervical cancer is a well controlled disease thanks to the diffusion of Pap test and, in particular, to organized screening programs, which are able to detect and treat pre-invasive lesions (cervical intraepithelial neoplasia, CIN). The human papilloma virus (HPV) has been recognised as the necessary, but not sufficient, cause of cervical cancer, so a new screening test based on the identification of high risk (HR) HPV types has been developed(HPV DNA test). This test has demonstrated to be more effective than cytology in reducing the incidence and the mortality of cervical cancer, but it is less specific, so the use of a test triage is necessary to reduce the number of colposcopies and the risk of over-diagnosis (due to the potential regressivity of pre-invasive lesions). Until now, the triage test used is the cytology (Pap test). Recently specific biomarkers (mRNA and p16 tests) have been introduced for high grade CIN, targeting the molecular alterations strictly associated to transformation rather than simply detecting HR-HPV infections. These tests are more specific than HPV DNA test with a modest reduction of sensitivity for high-grade lesions. This is a multicenter randomised trial nested into some Italian screening programs based on the use of HPV DNA test as primary test. All women with positive HPV DNA test will be tested for cytology and also for mRNA and p16. Women with positive cytology will be referred to colposcopy, while women with negative cytology will be randomized into two arms. This study aims to evaluate if mRNA and p16 could be used as test of triage of HPV DNA or as a primary screening test with direct sending in colposcopy. In particular the main objectives are: - Measuring the cumulative detection rate of CIN2+ in the five years following a HPV DNA positive test and mRNA or p16 negative. - Measuring the potential reduction of overdiagnosis of using mRNA or p16 test instead of DNA, with direct sending in colposcopy - Measuring the reduction of overdiagnosis of cytological triage or triage with mRNA or p16 compared to the direct sending in colposcopy in women with HPV DNA test positive. Secondary objectives are: - to assess the feasibility of mRNA testing in primary screening - to validate the sample techniques for the new tests - to standardize quality controls for the the new tests
This study is intended to determine the positive predictive value (PPV) and negative predictive value (NPV) of the multiprotein classifier based on the observed study prevalence of Non-Small Cell Lung Cancer (NSCLC) in the study participants.
The primary objective is to identify a panel of plasma and/or serum proteins that differentiates the absence or presence of lung malignancy in samples obtained from subjects enrolled in this IRB/EC approved study with pulmonary nodules.
To evaluate clinical outcome for patients receiving treatment of suspected premalignant and malignant gastrointestinal lesions at Interventional Endoscopy Services. The primary outcome is curative endoscopic resection. Secondary outcomes include resection technique utilized, rates of en bloc resection and adverse event rates, including infection, bleeding, perforation and death, and one-year survival rates.
