Active clinical trials for "Neoplasms"

Red cell transfusions are an important part of supportive cancer therapy. The iron in the transfused blood may build up in the body since the human body has no way to get rid of extra iron. Iron tends to build up in the liver and the heart muscle. It is unknown if iron build-up is present many years after completing cancer therapy. It is also not known if extra iron causes harm to internal organs. Researchers at St. Jude Children's Research Hospital (SJCRH) want to understand if iron build-up (called "iron overload") exists in survivors of leukemia. They also want to know if iron overload can cause injury to your organs if it is present. Liver iron accumulation has been documented in childhood cancer survivors, however, it is not known if iron associated organ toxicity is contributing to the long-term morbidity that has been well documented among these survivors. This study will investigate the prevalence of iron overload and the association of tissue iron burden with markers of organ dysfunction in leukemia survivors. This study will determine the prevalence of iron overload among long-term leukemia survivors that underwent blood transfusion. This study will use blood and magnetic resonance imaging (MRI) testing to determine iron overload of specified organs. Understanding the prevalence of iron overload could impact surveillance practices in leukemia survivors. PRIMARY OBJECTIVE: To determine the prevalence of iron overload in the liver [liver iron concentration (LIC) >3mg/g using R2* MRI measurements] and in the heart (T2* <20 ms) among long-term leukemia survivors transfused with ≥50ml/kg of packed red blood cells. SECONDARY OBJECTIVES: To examine the relationship between hepatic, cardiac, and endocrine dysfunction and transfusionally acquired iron overload as defined by R2* and T2* MRI among survivors of pediatric leukemias. To investigate the association between serum ferritin, transferrin saturation, non-transferrin-bound iron, and hepcidin measurements with R2* and T2* MRI-defined iron overload.

Prometheus's Onco dX assay platform provides technological breakthrough for immunoassay by obtaining a level of sensitivity down to single tumor cells without compromising specificity. This allows assessment of multiple TKI treatment targets, their activation status, as well as down stream signaling proteins using very tiny amount of tissue that can be obtained by FNA or CTCs. We planned this study to explore biomarkers predictive of clinical response to cetuximab-based treatment in metastatic colorectal cancer using the Prometheus Platform. We will also elucidate signal transduction pathway attributable to cetuximab resistance, monitor changes in the RTK activation status during cetuximab treatment using circulating tumor cells and analyze correlation between the quantity of circulating tumor cells and treatment response to cetuximab.

Lambert-Eaton Myasthenic Syndrome (LEMS) is a rare autoimmune disorder which affects the nerve-muscle junction. The major symptoms of LEMS are progressive muscle weakness. Many patients experience other symptoms like dry mouth or impotence. Congenital Myasthenia (CM) is an inherited disorder with similar affects and symptoms. 3,4-Diaminopyridine (DAP) is an experimental drug that has improved strength in some subjects with (LEMS). There are no other accepted treatments for LEMS and DAP has relatively few side effects.

schema : Prospective prognostic study The main objective is to study the value of the Comprehensive Geriatric Assessment in predicting the risk of post operative complications after lung resection for cancer.

The study aims to evaluate the molecular mechanism underlying the erythroid response observed in some patients with myelodysplasia, myelofibrosis and aplastic anemia treated with Deferasirox or Deferoxamina.

The purpose of this study is to establish the Six-Minute Walk Test, 10-Meter Walk Test, 30 Second Chair Stand, Linear Analog Scale of Function, and the Modifed Brief Fatigue Inventory as reliable and valid outcome measurements for patients with head and neck cancer.

Few data are currently available in the literature on pancreatic adenocarcinoma in France. About 8,000 new cases each year in France. The 5-year survival for all stages combined is <5%. This is the only digestive cancer in which mortality / incidence ratio is 98%. Epidemiological characteristics at diagnosis, the impact on the survival of recent advances related to surgery, adjuvant chemotherapy and new standard forms of adjuvant chemotherapy (FOLFIRINOX) are mispriced in real life. The development of new drugs and the development of Phase II and III require a better understanding of the state of this disease in the country. The main objective is to describe the characteristics of the pancreatic adenocarcinoma at diagnosis in France and make an inventory of diagnostic practices and support.

This is a study to assess the motion of pancreatic tumors during radiation therapy using Computed Tomography (CT) Scans and an Active Breathing Control (ABC) Device.

In the diagnosis of lung cancer, the cytological sample obtained during Bronchoscopy (FBS), has an increasingly important role in the characterization of malignancy. The cytological sample can be harvested during bronchoscopy by bronchial brushing, bronchial lavages or fine needle aspiration. Immunocytochemical staining allows not only to discriminate between small cell lung cancer versus non-small cell lung cancer (NSCLC), but also to identify the expression of specific markers such as TTF-1, CK7, CK20, 4A4, 34βE12 and p63. Thin Prep is a technique for cytological assay already validated and largely used in the immunocytochemical determination of gynaecologic specimens. Further Studies are required to asses the accuracy of this technique compared to conventional smear in cytological airway samples obtained by fine needle aspiration.
