Active clinical trials for "Neoplasms"

Several reports have examined Programmed Death 1 (PD-1) expression on tumor-infiltrating T-cells, and its correlation with prognosis has been discussed. However, Programmed Death 1 (PD1)/Programmed Death Ligand 1 (PDL1) expression on the peripheral blood T-cells of cancer patients, particularly in those with lung cancer, has not been sufficiently studied. The purpose of this study is evaluate the expression of PD1 and PDL1 in subpopulations of peripheral blood and tumor cells patients with lung cancer non-small cell (NSCLC), associating with clinicopathological features of the patients studied.

The purpose of the research study is intended to use specimens (such as tissue) and medical information in the Laboratory of Musculoskeletal Oncology at the Van Andel Research Institute for laboratory research in Grand Rapids, Michigan. Small tissue samples of cutaneous neurofibromas will be collected as part of this research. The samples will help researchers learn more about cutaneous neurofibroma and help them better understand NF1. There are many different types of studies, both now and in the future, that can be done using the specimens they receive. These include using the specimens and information to look for new ways to diagnose and treat Neurofibromatosis Type 1 (NF1). The specimens may be used to study how genes affect health and disease, or how genes affect the way a disease or condition responds to treatment. Some of these studies may lead to new products, such as treatments or tests for diseases. Through this study, we hope to find better ways to understand and treat NF1 in the future.

This data base has been set in order to gather oncogeriatric information from elderly patients with pancreatic cancer who underwent an oncogeriatric evaluation. ONCOGEPAN database gathers data from deux institutions (Institut Paoli-Calmettes and Assistance Publique des Hôpitaux de Marseille) involved in Marseille SIRIC (Integrated Cancer Research Site).

BACAP is a biobank dedicated to the pancreatic adenocarcinoma funded by institut national institue du cancer (INCa) and coordinated by Dr Barbara Bournet from Toulouse hospital. This base includes clinical data and biological samples such as blood, serum, plasma, saliva, DNA and RNA from tumors cells. The mission of this prospective project is to make available to the scientific community a clinical biological base from patients with pancreatic adenocarcinoma

Treatment of a stage IV NSCLC is based on chemotherapy and requires before each session to check clinically, biologically and radiologically absence of infection. This biological evaluation is based on the CRP rate. Lots of infections may occur in this situation and could reduce by three the patient's life duration. However it is very important to make as early as possible a correct diagnosis of infection. CRP rate is classically higher for those patients even without any infection. In comparison with CRP, Procalcitonin (PCT) is well-known for its better sensibility and specificity for the infection diagnosis but has never been study in case of active cancer. The aim of this study is to evaluate the Procalcitonin basal rate for those patients suffering from NSCLC. It could be a simple and reliable method to use. So the investigators decided to include each new patient with NSCLC stage IV coming for his first-line chemotherapy without any infection sign, and to realize a Procalcitonin dosage before the start of the treatment. This sample will be analyzed at the chemical laboratory and the result will not be communicated to the patient physician. A new clinical evaluation will be realized either at the hospital or by phone at day 7 to search any sign of infection. In absence of infection, patient will be reevaluated at day 14, 21 and 30. In case of infection, a new Procalcitonin (and CRP) dosage will be performed.

Magnetic resonance imaging (MRI) has been widely used for problem-solving tool in the evaluation of hepatic lesions, and it has been shown to have better sensitivity than CT for detection of colorectal liver metastases, especially for lesions which are smaller than 1 cm. After introduction of a liver-specific hepatobiliary MR contrast agent, gadoxetic acid, gadoxetic acid-enhanced MRI (Gd-EOB-MRI) has been increasingly used for evaluation of liver lesion including CRLM. However, compared to conventional MRI with extracellular contrast agent (ECA-MRI), Gd-EOB-MRI has different pharmacodynamic characteristics, and is more expensive due to higher cost of gadoxetic acid and needs longer scan time to obtain hepatobiliary phase which is generally acquired 15 to 20 minutes after contrast injection. The purpose of this study was to compare the clinical outcome and diagnostic performance of Gd-EOB-MRI and ECA-MRI for evaluation of focal hepatic lesion in newly diagnosed colorectal cancer.

observational prospective study, designed for patients with colorectal cancer receiving for the first time 5-FU or capecitabine, with or without other chemotherapy combinations.

Early monitoring of antineoplastic treatment benefit is a central medical need. Radiologic assessment for documentation of response is done after several months of treatment usually. This implies that patients not responding are exposed to unnecessary toxicity. According to several reports showing the correlation of the amount of circulating tumour DNA with tumour burden we aim to investigate its early dynamic change at the beginning and during antineoplastic treament until radiologic response assessment. Blood samples necessary for that are taken within the scope of clinical routine care. We hypothesize that the changes of circulating tumour DNA correlate with the radiological findings.

From the medical records of a series of patients operated on for incident grade II and III glioma, the primary objective is to evaluate the correlation between the molecular profile of tumours and preoperative imaging data (by FDG and FDOPA PET-scan and multimodal MRI).

Myeloproliferative neoplasms (MPNs), including polycythemia vera, essential thrombocythemia, and primary myelofibrosis, may lead to gastroesophageal varices. The quality of life, morbidity, and mortality of MPN patients mainly depend on disease-related symptoms, thromboembolic and hemorrhagic complications. Previous studies have shown that JAK2 V617F has a prominent role in vascular risk and MPN-associated gastroesophageal varices. Portal vein thrombosis and portal cavernoma frequently occur in the MPN population and the management of gastroesophageal varices in these patients are sometimes technically difficult. The aim of this study is to investigate the the characteristics of patients with gastroesophageal varices and portal caver cavernoma with or without JAK2 mutation.
