Active clinical trials for "Colonic Neoplasms"

The purpose of this study is to test the safety and find the response rate of combining the dietary supplement, curcumin, with the standard of care, FDA-approved chemotherapy drug 5-fluorouracil (5FU, Adracil) and see what effects (good and bad) that the combined treatments have on colon cancer.

Registry participants with advanced malignancy or myelodysplasia will have a sample of their tumor or tissue analysed for genetic alterations using next generation sequencing (NGS) performed in a lab that has been certified to meet a high quality standard. Treatments and outcomes will be reported to the registry to allow further understanding of how genetic differences can lead to better diagnosis and treatments.

Purpose: To demonstrate the bioequivalence between Capecitabine Tablets 500 mg of Qilu Pharmaceutical Co., Ltd, China in comparison with XELODA® (Capecitabine) Tablets 500 mg, Distributed by Genentech USA, Inc. Design: two treatment, three period, three sequence, reference replicate crossover, single dose. Test Drug: Capecitabine Tablets; Reference drug: XELODA Sample size: Around 45 patients will be enrolled to have at least 39 evaluable patients in the study.

The purpose is to evaluate the effectiveness of high dose intravenous vitamin C (IVC) therapy plus very low carbohydrate diet (VLCD) for stage IV colon cancer (with KRAS and BRAF mutation ) with or without chemotherapy.

Background of the study: Colon cancer is the second leading cause of cancer-related death world wide. Although patients presenting with early disease (stage I-III) can be cured, prognosis varies from 90% in stage I to 50-80% in stage II and III. Therefore, prevention of metastases after early disease is of utmost importance. Derepression of Wnt targets may provide a novel target for therapy. Objectives: The primary objective of the study is to assess in patients with primary colon cancer whether short-course pre-operative treatment with decitabine can increase Wnt target gene expression as measured in resected tumors compared to pretreatment biopsies. The secondary objective of the study is to assess in patients with primary colon cancer whether short-course pre-operative treatment with decitabine can revert CpG methylation and induce more favorable tumor characteristics as measured in resected tumors compared to pretreatment biopsies. The tertiary objective is to compare changes in Wnt target gene expression, CpG methylation and tumor characteristics for Wnt methylated and nonmethylated tumors as measured in resected tumors compared to pretreatment biopsies and identify new stratification markers.

Screening colonoscopy has been shown to be less effective in preventing colorectal cancer in the proximal colon compared to the distal colon. Possible reasons for this include bowel preparation often being worse in the proximal colon as well as flat depressed lesions being more common in the proximal colon. Retroflexion is commonly regarded as standard practice in the rectum, but retroflexion in the proximal colon is not currently routinely performed due to concerns of perforation and possibly because of the increased time required. Proximal colon retroflexion has been shown to be safe and effective without any complications, but data regarding ability to retroflex with certain types of colonoscopes is limited. Endoscopists interchangeably use standard adult colonoscopes or pediatric colonoscopes. Studies have not been performed to comparatively evaluate the success rates of standard adult and pediatric colonoscopes and whether either type of instrument confers a greater polyp detection rate.

This trial is to evaluate the safety and efficacy of using MASTER, a robotics enhanced endosurgical system to perform endoscopic submucosal dissection (ESD) of gastric/colon cancer in human.

This study aims to compare the outcomes of patients who undergo single-port laparoscopic colectomy and conventional laparoscopic colectomy for colonic neoplasia (large polyp not amenable to endoscopic removal/ cancer) through a randomized controlled trial. After informed consent, patients will be randomized to have either conventional or single-port laparoscopic colectomy by a team of surgeons with good experience in laparoscopic colorectal surgery. Patients' demographic, operative detail and post-operative outcomes including operating time, blood loss, complications, pain score, analgesic requirement, resumption of gastrointestinal function and length of hospital stay will be recorded prospectively. The patients will be blinded to the type of treatment that they have received during the first three days after operation (post-operative pain and analgesic requirement will be recorded in these period). Patients will have long term up to record for cancer recurrence and survival. The results of two groups of patients will be compared scientifically to assess if single-incision laparoscopic colectomy results in any difference in outcomes when compared to conventional laparoscopic colectomy.

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Heating mitomycin C to several degrees above normal body temperature and infusing it into the area around the tumor may kill more tumor cells. Giving mitomycin C after surgery may kill any remaining tumor cells. It is not yet known whether standard therapy is more effective with or without surgery followed by mitomycin C. PURPOSE: This randomized phase III trial is studying standard therapy with or without surgery and mitomycin C in treating patients with advanced limited peritoneal dissemination of colon cancer

This study is designed to investigate the dietary influence of grapes in colon cancer prevention. A natural compound found in the skin of grapes, resveratrol, may protect against cancer by acting as an antioxidant (a chemical compound or substance that helps reduce damages due to oxygen). This compound is known to block colon cancer cell lines from growing in the laboratory. The purpose of this study is to determine the minimum amount of resveratrol-rich fresh red grapes needed to exhibit such signs of prevention.
