NCT00032344
Colorectal cancer is a leading cause of cancer death in the United States. Mortality remains high because most colorectal cancers are detected after there has been regional or distant spread, precluding curative surgical resection. With this in mind, screening strategies have been recommended for asymptomatic individuals which hope to reduce mortality from colon cancer by detecting and removing premalignant adenomatous polyps or early malignant lesions. Screening of asymptomatic individuals over age 50 with sigmoidoscopy and fecal occult blood tests has been advocated by the American Cancer Society. However, current screening will identify only 50% of patients who have adenomatous polyps. More sensitive tests for polyp detection, like colonoscopy, are costly, require extensive resources and are unlikely to be used for screening large populations. Ideal screening would identify patients with the highest risk of cancer and target more sensitive screening tests at this population. The identification of low cost, easily collectible risk factors which can be used to target patients for the more sensitive screening tests is the primary purpose of this study. Since a major segment of the veteran population is over the age of 50, there will be a substantial impact in reduction of both mortality and morbidity due to colon cancer and attendant cost savings to the VA for treatment if such risk factors can be identified. Phase I is a cross-sectional study designed to identify risk factors for large (\>1 cm) adenomatous polyps. Approximately 3200 asymptomatic subjects (age 50-75) have completed risk factor assessment, medical and dietary histories, and have undergone complete colonoscopy examination. This will identify for comparison purposes a polyp-free control group and is the first large prospective study to include such a group. Data at colonoscopy will characterize the prevalence, size and distribution of adenomatous polyps. This will permit an assessment of sensitivity of sigmoidoscopy in this population. In addition, tissue from normal rectal mucosa will be analyzed for evidence of cell proliferation activity. The primary focus of Phase I is a risk factor analysis. A multivariate analysis will be performed to determine the relationship of historical and environmental factors as well as cell proliferation activity with the presence of adenomatous polyps. A cohort consisting of a subgroup of polyp patients (large and small) and matched polyp-free controls will be tracked longitudinally to determine polyp occurrence/recurrence rates. Phase II of the study is a long-term follow-up study designed to evaluate the relative risk of two repeat colonoscopies. Phase III is an extension in follow-up of an additional five years, a total of ten years in all, to include all study patients. The primary focus will be on documenting long-term mortality and medical outcomes as well as occurrence/reoccurrence of neoplasia with special emphasis on ten-year cancer rates.
NCT00002575
RATIONALE: Less invasive types of surgery may help reduce the number of side effects and improve recovery. It is not yet known which type of surgery is more effective for colon cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of laparoscopic-assisted colectomy with open colectomy in treating patients who have colon cancer.
NCT00023751
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining surgery with chemotherapy and radiation therapy may kill more tumor cells and prevent recurrence of the cancer. PURPOSE: Phase II trial to study the effectiveness of surgery with or without chemotherapy and radiation therapy in treating patients who have stage I rectal cancer.
NCT00724503
This study is a randomized multi-center trial that will assess the effect of adding Selective Internal Radiation Therapy (SIRT), using SIR-Spheres microspheres®, to a standard chemotherapy regimen of FOLFOX as first line therapy in patients with non-resectable liver metastases from primary colorectal adenocarcinoma. Treatment with the biologic agent bevacizumab, if part of the standard of care at participating institutions, is allowed within this study at the discretion of the treating Investigator.
NCT02119676
The purpose of this study was to determine if ruxolitinib, in combination with regorafenib, is safe and effective in the treatment of metastatic colorectal cancer.
NCT00836992
RATIONALE: Gathering information about patients' quality of life during radiation therapy for cancer may help doctors plan the best treatment. PURPOSE: This randomized clinical trial is studying quality of life in patients undergoing radiation therapy for primary lung cancer, head and neck cancer, or gastrointestinal cancer.
NCT01383343
This phase I trial studies the side effects and best dose of sorafenib tosylate when given together with bevacizumab, irinotecan hydrochloride, leucovorin calcium, and fluorouracil in treating patients with colorectal cancer that has spread to other parts of the body. Drugs used in chemotherapy, such as irinotecan hydrochloride, leucovorin calcium, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. Sorafenib tosylate and bevacizumab may also block tumor growth in different ways by targeting certain cells. Giving sorafenib tosylate and bevacizumab together with combination chemotherapy may be a better treatment for colorectal cancer.
NCT02033551
This is an extension study to evaluate the safety of Veliparib monotherapy or in combination with Carboplatin plus Paclitaxel or modified Folinic Acid/Fluorouracil/Irinotecan (FOLFIRI) in subjects with solid tumors.
NCT00003674
RATIONALE: Dalteparin may be effective in inhibiting the growth of blood vessels in tumors, decreasing the risk of metastatic cancer, preventing the formation of blood clots, and improving quality of life in treating patients with advanced cancer that has not responded to previous treatment. It is not yet known if standard therapy is more effective with or without dalteparin in treating advanced breast, lung, colorectal, and prostate cancer. PURPOSE: Randomized double blinded phase III trial to compare the effectiveness of standard therapy with or without dalteparin in treating patients who have advanced breast, lung, colorectal, or prostate cancer that has not responded to previous chemotherapy or hormone therapy.
NCT00003834
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients with liver metastases from colorectal cancer.
NCT01936961
The purpose of this study is to use Immunochemotherapy +/- Hypofractionated Radiation for complete response in solid tumors
NCT00642603
This 2-arm study was designed to evaluate the efficacy and safety of 2 treatment regimens of Xeloda and Avastin, with either irinotecan or oxaliplatin administered for the first 12 cycles, as first line treatment in patients with metastatic colorectal cancer. Patients were randomized to receive 2-weekly cycles of treatment with either: 1) Xeloda, Avastin and oxaliplatin; or 2) Xeloda, Avastin and irinotecan. After 9 cycles, patients continued to receive maintenance treatment with Xeloda + Avastin. The anticipated time on study treatment was until disease progression, and the target sample size was 100-500 individuals.

NCT00911170
This is a phase 3, randomized, double-blind, placebo-controlled multi-center study evaluating the efficacy of pegfilgrastim to reduce the incidence of febrile neutropenia (FN) in patients with newly diagnosed, locally-advanced or metastatic colorectal cancer receiving first-line treatment with bevacizumab and either 5-fluorouracil, Oxaliplatin, Leucovorin (FOLFOX) or 5-fluorouracil, Irinotecan, Leucovorin (FOLFIRI). This study will also investigate the effect of adding pegfilgrastim to bevacizumab and either FOLFOX or FOLFIRI by evaluating overall survival, progression-free survival, and overall response rate in each arm at regular intervals over a maximum of 60 months follow-up.
NCT00873756
This is a multicenter, open-label study enrolling a total of up to 23 patients.
NCT00153816
Extensive experimental and observational data suggest that intake of calcium and of vitamin D exert protective effects on colorectal neoplasia. Building on their previous work, the investigators will investigate the chemopreventive effect of vitamin D in the large bowel, to study whether calcium with vitamin D is more effective than calcium alone, and to confirm their positive finding regarding calcium. The goal of this study is the development of chemopreventive combinations that will reduce risk of colorectal neoplasia sufficiently to permit the lengthening of surveillance intervals in most patients and to clarify important issues regarding the mechanisms of colorectal carcinogenesis and chemoprevention.
