Experimental Device to Improve Colonoscopy
ColonoscopyLooping2 moreThis study will test the use of a new device called a segmental stiffening wire (SSW) in colonoscopy to correct a problem called looping. Colonoscopy is the best test for detecting early colon cancer and removing growths called polyps, which can become colon cancer. Sometimes the flexible tube (colonoscope) used in the procedure loops at a certain point as it advances through the colon, making it difficult to move further and causing the patient pain from excessive stretching of the colon. The SSW is designed to prevent this by stiffening the part of the tube that would otherwise form the loop. Healthy subjects between 50 and 80 years of age and healthy subjects 40 years and older who have a family history of colon cancer may be eligible for this study. Participants undergo colonoscopy a day after self-administering a bowel cleansing preparation. The first part of the procedure is done similarly to that of a flexible sigmoidoscopy, and no sedation or pain medication is used. The colonoscope is inserted into the rectum and advanced about one-third the length of the colon. Pain or discomfort should be mild to moderate cramping and a feeling of having to move the bowels. The subject is asked to score his or her pain level at this point using a standard pain scale. If there is pain, the procedure is stopped and an x-ray is taken to determine if the colonoscope has looped. If it has, the loop is undone and the SSW is used. Another x-ray is then taken to document that the loop has been prevented with the SSW, and the procedure is completed as per standard medical practice. Subjects are taken to the recovery area, informed of the test results and then discharged home in the care of an accompanying adult.

Therasphere® for Treatment of Unresectable Primary Liver Cancer and Metastatic Liver Cancer
CarcinomaHepatocellular1 moreThe purpose of this protocol is to provide supervised and limited access to Therasphere® treatment for patients with primary liver cancer and chemotherapy refractory liver metastasis who cannot be treated by surgical removal of the affected part of the liver. Patient response to treatment and any side effects of Therasphere® treatment will be examined.

Inflammatory Cytokines in Symptom Production in Multiple Myeloma
Multiple MyelomaThe goal of this research study is to learn about the pain and/or other symptoms that patients may experience either while you are being monitored by your doctor before a decision is made to start you on treatment for your MM, or during and after treatment for MM, and how these symptoms may affect therapy. A second goal is to learn how differences in genes may affect the symptom burden from cancer and cancer therapy.

Evaluation of Four Reconstructions After Total Gastrectomy
Gastric CancerNutritionThere are four capital reconstructions after total gastrectomy which is widely used in China. Life quality is the only standard to evaluate postoperative results of different reconstructions. In order to determine the best reconstruction after total gastrectomy, we designed this study to compare life qualities of four reconstructions.

Role of CXCR2 Ligands/CXCR2 Biological Axis in Pancreatic Cancer
Chronic PancreatitisPancreatic CancerThe investigators hypothesize that the CXCR2 ligands/CXCR2 biological axis plays an important role in promoting angiogenesis in PC; and that the genetic changes and the microenvironment of the tumor regulate the expression of CXCR2 ligands/CXCR2 in PC in order to potentiate their angiogenic phenotype. A corollary of this hypothesis is that the cell surface receptors (CXCR2) and the intracellular signaling pathways that mediate the angiogenic responses induced by ELR+ CXC-chemokines are potential targets for novel therapeutic interventions in PC.

Survey on QUality of Life In myeloDisplasia (SQUID)
Myelodysplastic SyndromesThe purpose of this study is to evaluate the correlation between quality of life (QoL) and hemoglobin in patients affected by myelodysplastic syndrome and to compare the MDS (MyeloDisplastic Syndrome) patient's self-assessed QoL according to physician's evaluation

Motion Correction in Dynamic Contrast Enhanced Magnetic Resonance Imaging (MRI) in Ovarian Cancer:...
Ovarian CancerThe purpose of this study is to develop new image analysis method using Dynamic Contrast Enhanced Magnetic Resonance Imaging (DCE-MRI) for ovarian cancer. MRI is not currently part of the standard care for ovarian cancer. In this method, a contrast agent is used to make ovarian cancer visible during imaging.

A Longitudinal Study of Plasma EBV DNA in Nasopharyngeal Carcinoma From Both Endemic and Non-Endemic...
Mouth CancerLip Cancer3 moreTo determine the prognostic implication of plasma Epstein-Bar Virus (EBV) DNA concentrations, as measured by quantitative polymerase chain reaction (PCR) in patients with nasopharyngeal carcinoma (NPC). To relate pretreatment plasma EBV DNA concentration to WHO classification of these tumors both in endemic and non-endemic areas. To determine whether pretreatment plasma EBV DNA can serve as a prognostic factor for both endemic and non-endemic patient populations.
