Active clinical trials for "Neoplasms"

Lung neuroendocrine tumor (LNT) represents approximately 20% of all lung cancers. The classification of LNT relies upon morphology. Recently, in the World Health Organization (WHO) classification, Ki-67 rate has been proposed for classi fication. It is, however, known that Ki-67 count has a poor interlaboratory reproducibly. For that reason, our team has looked for a new biomarker. GLUT1 protein a facilitative glucose transporter protein which has ubiquitous expression in mammalian. GLUT1 is overexpressed in many human cancers. But, no study has evaluated the GLUT1 staining as an aid diagnosis in LNT. The team have assessed the GLUT1 immunohistochemical staining in 36 LNT and to assess its diagnostic value.

This study aims to assess the 6- and 12-month venous thromboembolism (VTE) and bleeding incidence from the start of cancer diagnosis in a retrospective cohort of patients with esophageal cancer. Additionally, the predictive value of the Khorana score and several other VTE and bleeding prediction scores and risk factors will be evaluated.

As part of an oral treatment regimen in ambulatory practice, certain uses in connection with drug consumption associated could alter treatment outcomes observed in randomized clinical trials. The increase in progression-free survival in myeloma may be accompanied by an impaired quality of life and a resurgence of pain symptoms over time, which could potentially lead to medication overuse involving painkillers but also psychotropic drugs. These combined consumption may affect survival through mechanisms of pharmacological or non-pharmacological interactions. As part of this project, we wish to explore the scheme of adherence to myeloma drugs, and thus validate the decision diagram of hypothesis of not adequate of drug use in ambulatory conditions, from observational data. This discrepancy could result from poor adherence or suboptimal drug use but also from concomitant exposures to other drugs which may interact with myeloma. Before considering a study of greater magnitude that could address the consequences of non optimal drug use on clinical response criteria, such as duration of response or survival, it seems appropriate to confirm these assumptions within ' an exploratory study.

Carcinoid tumors of the lung are considered to be a low-grade malignancy. Surgical resection is considered the standard approach. Recent data has shown that a complete endoscopic treatment could be considered. An endoscopic treatment is can be a alternative to invasive surgery.

The aim of our study is to compare MAP (mean adenoma per colonoscopy) with ADR (adenoma detection rate) and PDR (polyp detection rate) of all colonoscopists in our department

The primary objective is to confirm the specificity of a multi-target stool DNA test (mt-sDNA), Cologuard, in an average risk population, ages 45-49.

The intra-alveolar form of Pneumocystis jiroveci pneumonia (PjP) is a common pathology in immunocompromised patients, particularly those infected with HIV. The diagnosis is based on the detection of Pj in a LBA. Intra-tissue granulomatous form (PGP) is a rare entity observed in non-HIV immunocompromised patients. In this case, the LBA is mostly non-contributory and the diagnosis is based solely on the detection of cysts on histological examination on biopsy of a pulmonary nodule. For many years, it has been clearly demonstrated that the use of a specific PCR clearly improves the biological diagnosis of PcP. However, in case of granulomatous form this method is not implemented because the diagnostic hypothesis is not mentioned. In 2018, two cases of PGP were diagnosed at 3-month intervals at Montpellier University Hospital Center. The diagnostic confirmation was obtained with PCR Pj. In this context the investigators will investigate the interest of implementing PCR Pj on biopsies on pulmonary nodules from hospitalized patients between 2015 and 2018. In all selected patients, histopathological aspect of the nodule was compatible with a PGP and, no other diagnosis has been confirmed (infectious, tumoral, inflammatory ...). Finally, 17 patients were selected to check retrospectively, if the presence of Pj could be at the origin of the pathology.

The primary objective of this sub-study, 2018-10B, is to collect blood specimens to assess new biomarkers for the detection of Colorectal Cancer (CRC).

For bone lesions treated with chemotherapy or targeted therapy, particularly for sarcomas that originate in bones, Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 is spurious because bone lesions are typically located in irregularly shaped bones, are difficult to measure accurately, and usually respond more slowly to treatment than soft tissue lesions. Positron Emission Tomography Response Criteria in Solid Tumors (PERCIST) allows for response to be measured in the absence of anatomic changes through assessment of metabolic activity. It does not, however, account for morphologic changes. This study evaluated whether clinical imaging findings of sarcomas after preoperative chemotherapy correlate with tumor responses by pathological evaluation using the rate of necrosis to develop reliable and quantitative clinical response criteria.

This study aims to determine if a deep neural artificial intelligence (AI) network (NeuralSeg) can learn how to assign the Canada Lymph Node Score to lymph nodes examined by endobronchial ultrasound transbronchial needle aspiration(EBUS-TBNA), using the technique of segmentation. Images will be created from 300 lymph nodes videos from a prospective library and will be used as a derivation set to develop the algorithm. An additional100 lymph node images will be prospectively collected to validate if NeuralSeg can correctly apply the score.
