Active clinical trials for "Colorectal Neoplasms"

The purpose of this phase III study is to evaluate the safety and efficacy of the combination of eflornithine and sulindac compared to single agent sulindac or eflornithine in reducing the number of polyps in patients with familial adenomatous polyposis (FAP).

The Family Colorectal Cancer Awareness and Risk Education Project (Family CARE Project) is designed to determine whether a personalized telephone plus mailed print cancer risk assessment and behavior change counseling intervention is more effective than a targeted mailed print intervention in promoting risk appropriate screening in individuals with a family history of the disease. The project targets people residing in both rural and urban areas, allowing an examination of differential intervention effects with regard to place of residence.

The human body has a natural stress response to surgery, including the formation of blood clots. This response to surgery has been shown to increase metastases (the spread of cancer cells to other organs in the body). These metastases cannot be seen at the time of surgery but when they grow into new tumors, the cancer has recurred (come back). A blood thinner called "low molecular weight heparin" (LMWH) can suppress the development of metastases after surgery in animal experiments. The investigators want to see if giving patients with colorectal cancer the blood thinner, LMWH, around the time of surgery can decrease the chance of their cancer spreading to other organs (metastases) and coming back (recurrence). The investigators need 1075 patients to answer our scientific question. Patients who give informed consent will be randomly put into one of two groups, the experimental group and the control group. The patients in the control group will be treated with LMWH starting a few hours after surgery and every day until they leave the hospital. This is how most patients are treated after colon cancer surgery (standard care). The patients in the experimental group will be treated with LMWH for a longer period of time, starting on the day they agree to have surgery and continuing for two months after surgery. All the patients will be followed for at least three years after surgery to find out if their cancer has recurred (come back). If LMWH treatment around the time of surgery reduces the chance of recurrence in patients with colorectal cancer, it would improve the health and quality of life for these patients.

The purpose is to study the efficacy (effectiveness) of a new drug, MK-0646, in metastatic colorectal cancer. MK-0646 is an investigational or experimental anti-cancer agent that has not yet been approved by the U.S. Food and Drug Administration (FDA) for use in metastatic colorectal cancer or any other disease. This study will assess whether adding MK-0646 to an FDA-approved standard of care chemotherapy improves participants' duration of progression-free survival. MK-0646 is believed to inhibit the receptor of a protein called IGF-1 (Insulin-like Growth Factor) which is thought to contribute to cancer development and growth. However, there is no guarantee that MK-0646 will slow cancer development and growth. Other purposes of this study include: looking at the safety and tolerability of MK-0646 comparing MK-0646 + standard of care chemotherapy with placebo + standard of care chemotherapy (placebo is a substance that looks like an active drug but has no active ingredient) The standard of care chemotherapy in this study is called FOLFOX 7. FOLFOX 7 includes the drugs oxaliplatin with leucovorin, 5-Fluorouracil (5-FU), and bevacizumab.

The purpose of this study is to determine if ginger root extract when taken daily for 28 days is able to decrease levels of inflammatory chemicals called eicosanoids in the gut tissue of people who are at normal risk and those at increased of developing colorectal cancer compared to people taking placebo.

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: To determine whether a communication tool provided to patients will initiate a conversation with their primary care physicians about CRC screening, especially via colonoscopy. To determine whether this tool will impact referral patterns for screening, especially, although not primarily, among poor and underserved populations. 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

This randomized, open-label study will evaluate the safety and efficacy of Avastin (Bevacizumab) added to standard mFOLFOX6 chemotherapy in treatment-naïve patients with Stage IV metastatic colorectal cancer. According to K-RAS gene mutation status, patients will be assigned or randomized to receive either Avastin 5 mg/kg intravenously (iv) on Day 1 of each 2-week cycle or cetuximab 400 mg/m2 iv on Day 1 followed by 250 mg/m2 iv every week, in addition to mFOLFOX6 every 2 weeks. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs.

The purpose of this study is to demonstrate efficacy of the Avantis Third Eye Retroscope auxiliary imaging system. The primary objective of this study is to assess the degree to which incorporating the Third Eye Retroscope auxiliary imaging system in a screening colonoscopy setting results in the detection of additional polyps. Specifically, the primary goals are to estimate (1) the proportion of polyps detected under this protocol that would have been missed without the Third Eye Retroscope, and (2) the proportion of patients found under this protocol to have polyps who would have incorrectly been classified as polyp-free had the Third Eye Retroscope not been used.

The aim of the study is to determine if Iressa added to chemotherapy with Irinotecan, 5Fluorouracil and Leucovorin can prolong the period of time without any disease worsening (Time to Progression) in patients with metastatic colorectal cancer.

The follow up of colorectal cancer after curative surgery has to find loco-regional relapses or synchronous metastases, and to detect adenomas and new cancer on the rest of the colon. The increase of survival after relapse of the colorectal cancer depends on the possibility of curative action or after chemotherapy response. This is a Phase III open-labeled, multicenter, multidisciplinary, randomised study, comparing 2 arms of 188 patients (i.e. 376 total patients). Study Period (date of first inclusion/last inclusion): 3 years. Follow Up: 3 years. The primary objective is the evaluation of PET performance in the earlier relapse detection of the colorectal cancer relapse in comparison with conventional control (including carcinoembryonic [CEA] levels and other classic radiological exams).
