Filter by:RATIONALE: Measuring levels of transforming growth factor-beta (TGF-beta) in the blood of patients with epithelial cancers (head and neck, lung, breast, colorectal, and prostate) may help doctors predict how patients will respond to treatment with radiation therapy. PURPOSE: This research study is measuring levels of TGF-beta in patients with epithelial cancers who are undergoing radiation therapy.
RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors understand how patients respond to treatment. PURPOSE: This laboratory study is looking at gene expression in patients with advanced or metastatic colorectal cancer receiving bevacizumab.
This research trial studies tissue samples from patients with stage II colon cancer treated on Cancer and Leukemia Group B (CALGB)-9581 or CALGB-90903. Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer. It may also help doctors understand how patients respond to treatment.
RATIONALE: Collecting and storing samples of blood and tissue from patients undergoing colonoscopy to study in the laboratory may help doctors learn more about colon cancer and identify biomarkers related to colon cancer in the future. PURPOSE: This laboratory study is collecting blood and tissue samples for future colon cancer biomarker studies in patients undergoing colonoscopy.
RATIONALE: Studying samples of blood in the laboratory may help doctors predict which patients will develop hypersensitivity to cetuximab. PURPOSE: This research study is looking at hypersensitivity to cetuximab in patients with head and neck cancer or advanced colorectal cancer previously treated with cetuximab.
RATIONALE: Studying the genes expressed in samples of tissue from patients with cancer may help doctors identify biomarkers related to cancer. PURPOSE: This laboratory study is using gene expression profiling to evaluate normal tissue and tumor tissue from patients with colon cancer that has spread to the liver, lungs, or peritoneum.
RATIONALE: Diagnostic procedures, such as radionuclide imaging using bispecific antibody, may help find colorectal cancer cells and learn the extent of disease. PURPOSE: This phase I trial is studying how well a bispecific antibody works in finding tumor cells in patients with colorectal cancer.
Colorectal cancer is a major public health concern in Alberta. Colorectal Cancer is the fourth most common diagnosed cancer and second overall in terms of cancer deaths in Canada. One in 14 males and 1 in 16 females aged 50-74 will be diagnosed with colorectal cancer and will have an overall 1 in 28 chance of dying from colorectal cancer. While colorectal cancer is surgically curable if diagnosed in the early stages, with five year survival rates of 90% versus 10% if detected at more advanced stages, less than 20 % of all individuals in this age bracket traditionally have undergone colorectal cancer screening. Colorectal cancer often presents with non-specific symptoms where non-cancerous polyps are commonly found. If these polyps are left in place, they may grow over time and progress from a non-cancerous mass to symptomatic cancerous tumors; therefore, early screening in those patients without symptoms may thereby prevent the progression from a non-cancerous to cancerous finding. The hypothesis, or theory being studied in the SCOPE Pilot research study, is that implementation of a colorectal screening program would decrease colorectal cancer prevalence, increase the long-term survival ratio for patients, and decrease burden on the health care system. Moreover, early detection and treatment of colorectal cancer has the potential to increase the lifespan of patients and decrease health care costs. The SCOPE Pilot Research study will recruit 1000 individuals between the ages of 50 - 74 of average to high risk for developing colorectal cancer as determined by their referring Gastroenterologists. Those patients who are ages 40-50 will also be eligible if they have a personal or family history of colorectal cancer. Patients referred to the SCOPE Pilot program will be further screened for eligibility, and if no exclusion criterion is present, will be invited to attend an education session and research program. The SCOPE Pilot research study will compare the current fecal occult blood testing (FOBT - Hemoccult II) with newly available FOBT blood testing along with colonoscopy therapy. It will also encompass educational information, risk stratification, screening for both average and high risk patients, and colonoscopy.
RATIONALE: Screening may help doctors find colorectal cancer sooner, when it may be easier to treat. Finding out what affects a patient's decision to undergo screening tests may help increase the number of patients who undergo regular screening for cancer. It is not yet known whether personalized invitations to undergo colorectal cancer screening are more effective than standard screening reminders. PURPOSE: This randomized phase III trial is studying ways to increase colorectal cancer screening in African Americans.
This is a multicenter study designed to evaluate the response rate of S-1 plus Leucovorin (1 week on and 1 week off) as first -line treatment for patients with metastatic colorectal cancer.
