Filter by:This is a retrospective genetic analysis of stored tumor tissue samples to evaluate the distribution of Recurrence Score® and gene groups of stage II colon cancer in African American (AA) and Caucasian individuals. Other covariant factors in the medical chart will be analyzed as well. Three institutions will contribute patients to this study with a total patient number goal of approximately 200 with approximately 100 being AA and approximately 100 being Caucasian. As enrollment in this study proceeds a Caucasian subject will be matched for every African American enrolled.
This is a blinded randomized controlled trial in patients undergoing laparoscopic colon surgery. The aim of this study is to assess whether spinal analgesia with a mixture of bupivacaine and morphine provides better pain relief than systemic morphine in a group of patients undergoing colonic resection and using the Enhanced Recovery After Surgery (ERAS) program. Twenty patients will receive spinal analgesia and twenty patients will receive only Patient Control Analgesia (PCA).
This study is a parallel translational study of a Randomized Phase III trial Investigating the Role of Oxaliplatin duration (6 Cycles Versus 12 Cycles) in modified FOLFOX-6 Regimen as Adjuvant Therapy for Patients with Stage II/III Colon Cancer (MIDAS trial: protocol NCCCTS-467) . Patients participating in the trial will be provided with the informed consent of this parallel study, and peripheral blood and tumor tissue of those who signed the consent will be collected for germline polymorphism analysis and gene expression profile study .
The purpose of this project is to examine whether the risk of developing ovarian cancer is increased in Danish women with congenital missing teeth as a result of their failure to develop (hypodontia). Should this prove to be the case, these women could be offered regular clinical controls and prophylactic removal of their ovaries when menopause enters and the ovaries are no longer functional (producing hormones). If there is a connection between congenital hypodontia and the development of different types of cancer, the investigators will perform a genetic screening in families with increased risk of cancer and hypodontia for changes in relevant genes, based on the current literature. The investigators hereby search for new genes, which in a changed form leads to an increased risk of cancer and thereby enables us to perform genetic screening in risk families.
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 sets up the final study end point and three detailed goals as the following. The main objective of study: This trial is done to assess the safety and benefit of early adjuvant chemotherapy from 10 to 14 days after surgery compared with conventional commencement after 2weeks for treatment of patients with colon cancer. Detailed goal of study: The primary endpoint: This study is designed to assess whether early commencement of adjuvant chemotherapy improves the 3-year disease-free survival, overall survival and recurrence rate. The secondary endpoint: This study aims to compare short-term cumulative complications between early and conventional commencement of adjuvant chemotherapy after laparoscopic resection of colon cancer. This study will also assess the quality of life and side effects of chemotherapy.
It can be difficult to obtain the perspective of patients who have had bowel surgery. This study is being done because the investigators are trying to find out whether patient-reported outcomes, (results reported to investigators by the patient), on a regular basis, will help the investigators provide better patient care and symptom management. Therefore, the purpose of this study is to determine if it is possible and if it is useful to their medical care for patients who have had bowel surgery to complete surveys about their symptoms on a regular basis. In this study the surveys are completed from home, by web or by telephone, every month for 6 months. The results of this study will guide the design of large research studies on cancer-related bowel function. The purpose of this study is to develop a bowel function questionnaire for patients with colorectal cancer. The questionnaire will be used in future clinical trials to assess bowel function.
The study concerns a survey of attitudes of the public on issues around personal responsibility for health and the use of financial incentives to promote health in the U.S. and Germany. All data are gathered anonymously through online platforms. Two separate professional panel providers are used for access to members of the public. All participants are people who have voluntarily joined a survey panel in the past through an informed consent process and currently serve as panel members.
Background: - Some breast cancer cells have specific proteins (receptors) on their surface that make the tumor grow faster than normal cells. One of these receptors is called HER2/neu. - An FDA-approved drug called Herceptin attaches to HER2/neu if it is present on the cancer cell. - Indium-Herceptin is an agent in which a tiny amount of radioactivity called Indium has been attached to a tiny amount of Herceptin. Objectives: -To see if Indium-Herceptin provides information about the characteristics of the breast cancer in women whose tumors express HER2/neu and those whose tumors do not. Eligibility: -Women 18 years or older with primary or metastatic breast cancer who have not received treatment with herceptin for at least 6 months before enrollment into the study. Design: - Tissue from the patient s original breast or tumor biopsy is analyzed for HER2/neu status. - Patients have a physical examination and review of medical records. - Patients receive an injection of Indium-Herceptin, followed by scanning with a gamma camera that detects the radioactivity in the Indium-Herceptin. - Patients return to the clinic 1, 2, 3 and 7 days later for repeat imaging to determine the best time to image after injection of Indium-Herceptin. - Blood samples are obtained every day of scanning to monitor the effects, if any, of the Indium-Herceptin and to see how fast the agent leaves the body.
Metformin is drug that is normally used to treat people with diabetes. New research has discovered that metformin may also kill cancer stem cells. These cancer stem cells make up only a small portion of a cancer, but may be responsible for resistance to chemotherapy or for causing recurrence of the cancer. The purpose of this study is to determine the effect of metformin on colorectal cancer tumors. The study is designed to develop the methods to test tumors for cancer stem cells and then to determine the difference between treating with metformin and not treating with metformin with regard to the cancer stem cells. This research is investigational because the effect of metformin on cancer stem cells is not known in humans. Also, in patients who are not diabetic, metformin would normally not be given prior to surgery.
