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.
NCT00025025
RATIONALE: Screening tests may help doctors detect cancer cells early and plan more effective treatment for colorectal cancer. PURPOSE: Randomized screening trial to compare the effectiveness of fecal occult blood testing with that of DNA-based testing of stool and blood in identifying colorectal cancer.
NCT01397747
The primary objective is to determine the sensitivity and specificity of the Exact Colorectal Cancer (CRC) screening test for colorectal cancer, using colonoscopy as the reference method. Lesions will be confirmed as malignant by histopathologic examination. The secondary objective is to compare the performance of the Exact CRC screening test to a commercially available FIT assay, both with respect to cancer and advanced adenoma. Lesions will be confirmed as malignant or precancerous by colonoscopy and histopathologic examination.
NCT00075868
RATIONALE: Octreotide may be effective in preventing or controlling diarrhea in patients who are undergoing chemoradiotherapy for anal or rectal cancer. It is not yet known whether octreotide is effective in treating diarrhea. PURPOSE: This randomized phase III trial is studying octreotide in preventing or reducing diarrhea in patients who are undergoing chemoradiotherapy for anal or rectal cancer.
NCT00103142
RATIONALE: Vaccines made from a gene-modified virus and a person's white blood cells may make the body build an effective immune response to kill tumor cells. Biological therapies, such as Granulocyte-macrophage colony-stimulating factor (GM-CSF), may stimulate the immune system in different ways and stop tumor cells from growing. Combining different types of biological therapies may kill more tumor cells. PURPOSE: This randomized phase II trial is studying giving vaccine therapy together with dendritic cells to see how well it works compared to giving vaccine therapy together with GM-CSF in treating patients with liver or lung metastases from colorectal cancer removed by surgery.
NCT01773980
The goal of this project is to develop and pilot test an innovative approach for overcoming barriers to cancer screening among women with physical disabilities (WWD) in rural Oregon. Many studies have shown that people with disabilities receive fewer indicated cancer screening services and are more likely to have poor cancer-related outcomes, such as late stage at diagnosis, compared to those without disabilities.
NCT01260168
The objective of this study is to confirm the sensitivity of a stool DNA test for detection of colorectal cancer and pre-cancer. Another objective is to provide anonymous, clinically characterized specimens for a bio-repository for future colorectal cancer-related test development.
NCT00656838
FIBER is 4-year study that will evaluate the implementation of a large-scale population-based colorectal cancer screening patient reminder and coordinated follow-up program. The CRC screening program began in 2007 with Kaiser Permanente Northwest (KPNW),a not-for- profit, integrated health system in Oregon and Washington. FIBER consists of 1)a practical randomized controlled trial at the start of the program, followed by 2) a longer-term cohort study as all remaining eligible patients receive the program, and 3)a qualitative evaluation. FIBER will evaluate the factors that are associated with implementation success across multiple levels: patient, primary care provider (PCP) team, specialists (gastroenterologists, general surgeons, pathologists), and other health plan staff and systems.
NCT00027833
RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Tetanus toxoid may make tumor cells more sensitive to chemotherapy and vaccine therapy. PURPOSE: Randomized phase II trial to study the effectiveness of chemotherapy and vaccine therapy with or without tetanus toxoid compared with chemotherapy alone in treating patients who have metastatic colorectal cancer.
NCT00012389
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if irinotecan is more effective with or without oxaliplatin in treating metastatic colorectal cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of irinotecan with or without oxaliplatin in treating patients who have metastatic colorectal cancer.
NCT00077337
RATIONALE: Drugs used in chemotherapy, such as FR901228, work in different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: This phase II trial is studying how well FR901228 works in treating patients with unresectable locally advanced or metastatic colorectal cancer.
NCT00008281
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known which regimen of chemotherapy is more effective for metastatic colorectal cancer. PURPOSE: Phase III trial to compare the effectiveness of three chemotherapy regimens in treating patients who have metastatic colorectal cancer.
NCT00016198
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: Randomized phase II trial to study the effectiveness of combining fluorouracil and leucovorin with or without oxaliplatin in treating patients who have recurrent metastatic colorectal cancer.
NCT00005833
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of R115777 in treating patients who have recurrent or advanced colorectal cancer.
NCT00009737
This 2 arm study will compare the safety and efficacy of oral Xeloda, or 5-fluorouracil in combination with leucovorin, in patients who have undergone surgery for colon cancer. Patients will be randomized to receive either Xeloda 1250mg/m2 po bid on days 1-14 every 21 days, or leucovorin 20mg/m2 iv + 5-fluorouracil 425mg/m2 iv daily from day 1 to day 5 every 28 days. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.
NCT01189227
RATIONALE: Drugs used in chemotherapy work in different ways to kill tumor cells or stop them from growing. Giving combination chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving combination chemotherapy after surgery may kill any remaining tumor cells. It is not yet known whether giving combination chemotherapy before and after surgery is more effective than giving combination chemotherapy after surgery. PURPOSE: This randomized phase III trial is studying giving combination chemotherapy before and after surgery to see how well it works compared to giving combination chemotherapy after surgery in treating patients with colorectal cancer with liver metastases that could be removed by surgery.
NCT00003571
RATIONALE: Analyzing the structure of genes found in a person's cancer cells may help doctors improve methods of treating patients with colon cancer. PURPOSE: Clinical trial to study the genes of patients treated with chemotherapy for colon cancer.
NCT00048971
RATIONALE: Genetic testing may help predict how patients will respond to chemotherapy drugs and may help doctors plan more effective treatment with fewer side effects. PURPOSE: Genetic study to determine how genes affect the severity of diarrhea in patients with stage III colon cancer who are receiving chemotherapy.
NCT00006786
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Bevacizumab may stop the growth of colorectal cancer by stopping blood flow to the tumor. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy plus bevacizumab in treating patients who have advanced colorectal cancer.
