Filter by:The purpose of this research study is to explore ways to improve appropriate colorectal cancer (CRC) screening in the elderly by attempting to target screening in those most likely to benefit and avoiding screening in those least likely to benefit.
This is a study to determine if using Narrow-Band Imaging of the colon, rather than the usual white light on the colon, will improve the detection of a type of polyp called serrated. The polyps are called serrated because of their appearance under the microscope after they have been removed. They tend to be located up high in the colon, far away from the rectum. They have been definitely shown to be a type of precancerous polyp and it is possible that using Narrow-Band Imaging will make it easier to see them, as they can be quite difficult to see with standard white light.
The Ohio Patient Navigator Research Program (OPNRP) proposes to alleviate disparities in relation to the timely diagnosis and treatment of breast, cervical and colorectal cancer in Columbus, OH.
The purpose of this study is to demonstrate that NIR fluorescence angiography using the PINPOINT Endoscopic Fluorescence Imaging System ("PINPOINT System" or "PINPOINT") can assess viability of colon tissue during laparoscopic left colectomy. This information will provide the surgeon with clinically relevant information in assessing whether or not the tissue has adequate blood supply in the lower section of the colon prior to a colectomy.
Participants will be recruited from the United States and Australia to take an online survey about colon cancer screening or prostate cancer screening. Individuals selected for both the prostate cancer survey and the colon cancer study will be randomized to take one of three survey types - balance sheet, rating and ranking or conjoint analysis. These surveys will help participants clarify their values and opinions about screening options for colon cancer or prostate cancer. Participants' responses to the online survey are measured at one point in time - the time at which the participant takes the survey.
The PeerScope System consists of Peer Medical camera heads, endoscopes, video system, light source and other ancillary equipment. The system is intended for endoscopic diagnosis, treatment and video observation of the digestive tract. The PeerScope system model B is indicated for use for endoscopy and endoscopic treatment within the lower digestive tract (including the anus, rectum, sigmoid colon, colon and ileocecal valve) of adults patients. Objective:To compare the additional diagnostic yield obtained by using the PeerScope System™ extended view vs. the diagnostic yield obtained by the Standard view colonoscopy. In addition, time measurements including time to cecum, time for withdrawal and overall procedure time will be analyzed and reported for each group.
Background: - Cancer and cancer treatments can cause symptoms and side effects. Pain, fatigue, and emotional distress are three common symptoms. Accurate reporting of these symptoms can improve treatment methods and outcomes. Even though symptom reporting is important to treatment, there is no method to collect and compare patient data from multiple cancer care centers. Researchers want to develop a method for collecting cancer patient symptom information from multiple centers. This method may help improve cancer treatment at hospitals and other care centers. Objectives: - To collect patient-reported symptom information from multiple cancer care centers. Eligibility: - Individuals at least 21 years of age who were treated for breast or colon cancer in the past year. - Participants will come from one of the participating cancer care centers. Design: - Participants will answer a short questionnaire about their symptoms during cancer treatment. Questions will ask about symptom severity and experiences. Other questions will ask how well the doctors and nurses managed the symptoms. - Participant responses will be compared with other medical and personal information. This information may include cancer type, age at diagnosis, and type of treatment. - Treatment will not be provided as part of this study.
The investigators aim is to study the efficacy of mentholyptus drops in improving the palatability of PEG-electrolyte solution used in bowel cleansing for colonoscopy. The study is a randomized controlled trial which will include patients undergoing elective colonoscopy at the American University of Beirut Medical Center. Patients will be randomized into one of two study arms using a computer generated randomization list. Patients assigned to the intervention arm will be asked to have candy (Halls®) during the whole 2 hours period while drinking the PEG solution unlike the control arm patients who will only receive the PEG solution. All patients will then be evaluated for the tolerability of the preparation while taking into account the palatability of the solution as main outcome and the remaining volume of the PEG solution and side effects as secondary outcomes.
Colorectal cancer is the third most common cancer diagnosed and third leading cause of cancer-related deaths in the United States for both men and women. The American Cancer Society (ACS) estimates about 108,070 new cases of colon cancer and 40,740 new cases of rectal cancer will be diagnosed, and about 49,960 deaths will occur as a result of this devastating disease in 2008. Over the last 20 years, the death rate for this cancer has been dropping as a result of screening and early detection of cancer. In 2007, ACS reported that early-stage colorectal cancer had a survival rate close to 80%, and up to 9,632 deaths could be prevented each year if eligible patients received screening when necessary. However, despite the proven efficacy of colorectal cancer (CRC) screening, only about 50% of eligible US patients are currently being screened. Specific Aims The central hypothesis of this proposal is that patient-initiated prompting of primary care physicians of the patient's interest in screening will increase referrals for CRC screening. The following three areas will be investigated during this research: 1. To determine whether a communication tool provided to patients will initiate a conversation with their primary care physicians about CRC screening, especially via colonoscopy. 2. To determine whether this tool will impact referral patterns for screening, especially, although not primarily, among poor and underserved populations. 3. To determine whether differences exist in regard to patient-physician communication patterns about screening among residents and faculties in the fields of internal medicine and family practice clinics. At the close of the investigators study, the investigators wish to organize quantifiable data demonstrating how patient-initiated prompting of primary care physicians for CRC screening increases early detection and decreases potential mortality from colorectal cancer. This data will inform a second, larger study to pursue the questions surrounding patient-initiated prompting in
Background: - The Common Terminology Criteria for Adverse Events (CTCAE) is a list of toxicities and side effects that may occur when people are having cancer treatment. Doctors and nurses use this list to describe the side effects patients experience from cancer treatment. We have developed a questionnaire to ask people having cancer treatment directly about common symptoms and side effects and to supply this information to their doctors and nurses. This questionnaire is known as PRO-CTCAE and is completed by a patient. - PRO-CTCAE was originally developed in English. Researchers want to develop a Spanish version of the patient questionnaire. To test whether the questions are well understood and whether it is easy to complete the questionnaire, the researchers will interview individuals whose primary language is Spanish and who are being treated for different types of cancer. Objectives: - To test a Spanish version of the PRO-CTCAE questionnaire. Eligibility: - Latinos at least 18 years of age who are having or have recently finished cancer treatments and whose main language is Spanish Design: - Participants will complete a questionnaire in Spanish with selected questions from the translated PRO-CTCAE. They will discuss their answers and any difficulties they might have had in understanding or answer the questions with an interviewer, who will take notes and record comments and suggestions. - Literacy is not required for this study. Participants may opt to have the questions read aloud to them by an interviewer.
