Active clinical trials for "Intestinal Neoplasms"

RATIONALE: Monoclonal antibodies, such as alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from growing. Giving alemtuzumab together with combination chemotherapy may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of alemtuzumab when given together with combination chemotherapy and to see how well it works in treating patients with stage I , stage II , stage III, or stage IV peripheral T-cell lymphoma.

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is evaluating a tumor marker for testicular cancer, skin cancer, small intestine cancer, and pancreatic cancer.

Somatostatin receptors are overexpressed in GEP-NETs and can be visualized in vivo by radiolabeled somatostatin-analogs. During the last decades, conventional scintigraphy using 111In-DTPA-Octreotide (often named somatostatin receptor scintigraphy or SRS) was considered as the gold standard nuclear imaging technique in the evaluation of GEP-NETs. However, SRS may be suboptimal in this clinical setting because of the low intrinsic resolution of the technique and its selectivity for SST2 only. Its overall sensitivity is estimated to 60-70% (per lesion analysis), even when using the most recent SPECT-CT cameras. MRI have also a higher sensitivity than CT and SRS for the detection of liver metastases from GEP-NETs. In recent years, positron emission tomography (PET) imaging, a high resolution and sensitive technology, has gained an increasing role in oncology. It has also been evaluated in GEP-NETs with somatostatin agonists (SSTa) radiolabelled with Gallium-68 [68Ga], a positron emitter with very promising results. Its diagnostic sensitivity is clearly superior to SRS and many European centers have already replaced SRS by [68Ga]-PET-SSTa. Currently, three different [68Ga]-coupled peptides can be used in trials: DOTA-TOC, DOTA-TATE and DOTA-NOC with excellent affinities for SST2 (IC50: 2.5; 0.2 and 1.9 nM, respectively). Sensitivities of DOTA-TOC and DOTA-TATE PET/CT are quite similar. [68Ga]-DOTANOC which also binds to SST5 was recently found to detect significantly more lesions than the SST2-specific radiotracer [68Ga]-DOTATATE in patients with GEP-NETs but this requires further evaluation. It is therefore important to determine the interest of [68Ga]-DOTANOC combined with the standard diagnosis strategy in GEP-NETs and evaluate medicoeconomic impact of adding [68Ga]-DOTANOC in the work-up of patients. The investigators hypothesis is that [68Ga]-DOTANOC will modify the management in at least 20% of patients in a more adapted way according to the 2012 ENETS guidelines in comparison to the decision based on the standard imaging work up (multiphasic WB CT, liver MRI and SRS). 110 patients will be included prospectively in 5 different French experienced centers (Marseille, Bordeaux, Toulouse, Paris, Clermond-Ferrand).

This study evaluates the impact of Endorings™ assisted colonoscopy on the number of polyps detected per patient compared to standard colonoscopy without use of EndoRings™. Half of the participants will receive EndoRings™ assisted colonoscopy, while the other half will receive standard colonoscopy.

Deep learning technology has an increasing role in medical image applications and, recently, an artificial intelligence device has been developed and commercialized by Medtronic for identification of polyps during colonoscopy (GI-GENIUS). This kind of computer-aided detection (CADe) devices have demonstrated its ability for improving polyp detection rate (PDR) and the adenoma detection rate (ADR). However, this increase in PDR and ADR is mainly made at the expense of small polyps and non advanced adenomas. Colonoscopies after a positive fecal immunochemical test (FIT) could be the scenario with a higher prevalence of advanced lesions which could be the ideal situation for demonstrating if these CADe systems are able also to increase the detection of advanced lesions and which kind of advanced lesions are these systems able to detect. The CADILLAC study will randomize individuals within the population-based Spanish colorectal cancer screening program to receive a colonoscopy where the endoscopist is assisted by the GI-GENIUS device or to receive a standard colonoscopy. If our results are positive, that could suppose a big step forward for CADe devices, in terms of definitive demonstration of being of help for efectively identify also advanced lesions.

This study was conducted as a randomized controlled intervention study with repetitive measurements in a pretest-posttest order to examine the effect of nurse navigation program on compliance, quality of life and prevention of complications in patients with intestinal stoma. The study was completed with 30 experimental and 28 control group patients with intestinal stoma in six hospitals, two of which are training and research hospitals, located in Gaziantep city center, between January 1 and December 31, 2021. While counseling, remote support, written and visual trainings, informative messages, phone calls, and appointment scheduling were applied to the patients in the experimental group within the scope of the nurse navigation program, the patients in the control group received standard care

RATIONALE: Collecting information about the effect of hematologic cancer and its treatment on quality of life may help doctors learn more about the disease and plan the best treatment. PURPOSE: This phase I trial is studying quality of life in younger leukemia and lymphoma survivors.

Gastroentero-pancreatic neuroendocrine tumors (GEP-NETs) are a heterogenous group of neoplasms that arise from enterochromaffin cells of the gastrointestinal (GI) tract and pancreas. They account for 50-70% of all incident NETs. Due to the lack of symptoms in the early stage of disease and the frequency of nonspecific GI symptoms, GEP-NETs are difficult to diagnose. Identification of effective biomarkers (such as Chromogranin A) to improve GEP-NET diagnosis, as well as to assess treatment efficacy, relapse and prognosis, is important for improving outcomes for patients with GEP-NETs. The purpose of this study is to validate the performance of Brahms (BRAHMS) Chromogranin A II Kryptor (KRYPTOR) assay to monitor the course of disease in patients with well-defined GEP-NETs.

This study evaluates physical performance in cancer outpatients during a multimodal therapy. Half of the patients will receive physical exercise und nutrition program in combination with a specially formulated whey protein supplement, while the other half will receive standard care.

RATIONALE: Diagnostic procedures, such as visceral lymphatic mapping using isosulfan blue, may help find cancer of the pancreas, colon, stomach, small intestine, or gallbladder and find out how far the disease has spread. PURPOSE: This clinical trial is studying the side effects and how well visceral lymphatic mapping using isosulfan blue works in patients with cancer of the pancreas, colon, stomach, small intestine, or gallbladder.
