Filter by:Background: - Researchers are trying to learn what causes certain types of cancer to spread to other organs in the body (metastasis). Cancer tumors may produce a very small number of specific cells (cancer stem cells) that cause the tumors to grow in other organs throughout the body. - By examining cancer tumor tissue, normal tissue, blood, bone marrow, and other body fluids, researchers may determine whether these samples contain cancer stem cells. Cancer stem cells may provide information on whether the cancer will come back or spread before other routine x-ray studies or lab tests indicate its presence. Objectives: - To acquire a collection of solid organ cancer stem cells for future study. - To analyze solid organ cancer stem cells from various types of cancer on a genetic level. - To determine if solid organ cancer stem cells are present in the blood or bone marrow. Eligibility: - Patients 16 years of age and older who have solid organ cancer (cancer in the liver, colon, rectum, anus, pancreas, stomach, breast, skin, muscles, fat, connective tissue, uterus, ovary, cervix, vagina, vulva, or inner lining of the abdomen) or a precancerous growth, and who are scheduled to have a biopsy or surgery to remove the cancer as part of their treatment. Design: - This is a prospective trial designed to procure solid organ cancer stem cells before either surgery or biopsy. - All patients registered to this trial will undergo surgery to extirpate their cancer in the NCI - Prior to surgery or biopsy, 8 tablespoons of blood will be drawn. - During the surgery or biopsy, a sample of normal tissue will be removed along with the cancerous or precancerous tissue. If separate consent is given, samples of bone marrow will also be taken. - After discharge, patients will return to the clinic for routine visits every month for the first 3 months following surgery, and then about every 3 months for 2 years, and then every 6 months for 3 years. During the visits, patients will have routine blood and imaging studies done, and researchers will take additional blood samples (about 8 tablespoons at each visit) and optional bone marrow samples (4 teaspoons every 6 months) to be used for research.
The study is expected to identify a safe dose of BMS-754807 to be given in combination with a standard dose of cetuximab and the recommended dose or dose range for Phase II studies. The study is also intended to collect first data on the effects of the combination of BMS-754807 with cetuximab on tumors of patients with colorectal cancer or squamous cell cancer of the head and neck for whom cetuximab-containing therapies have not been effective
RATIONALE: Palonosetron hydrochloride may prevent nausea and vomiting caused by radiation therapy. It is not yet known whether palonosetron hydrochloride is more effective than a placebo in preventing nausea and vomiting. PURPOSE: This randomized phase II trial is studying the side effects of palonosetron hydrochloride and to see how well it works in preventing nausea and vomiting caused by radiation therapy in patients with primary abdominal cancer.
RATIONALE: Counting the number of circulating cancer cells in samples of blood from patients with metastatic cancer may help doctors find out how much the cancer has spread. PURPOSE: This research study is looking at the number of circulating cancer cells in patients with metastatic breast cancer, ovarian cancer, colon cancer, or pancreatic cancer.
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. The use of vitamin D may keep colorectal cancer from forming in patients with colon polyps. PURPOSE: This randomized phase I trial is studying a vitamin D supplement to see how well it works compared with a placebo in preventing colorectal cancer in African Americans with colon polyps.
Colon cancer is the second leading cause of cancer death in North America. These deaths are preventable with proper screening. Fecal occult blood testing, virtual colonoscopy, and standard (optical) colonoscopy are all options for colon cancer screening, but it is not known which is the best at preventing death from colon cancer. A large study comparing these three tests is desperately needed. In this pilot study, the investigators want to find out what percentage of patients will show up for their screening test once enrolled. This will provide crucial information for the successful execution of the larger study.
The purpose of this study is to evaluate whether patient outreach is effective at increasing compliance with preventative screenings for those patients who, based on national quality standards, have become newly eligible for screening measures. We hypothesize that educational outreach may increase completion rates.
The primary objective of the Phase II portion of this study is to assess the efficacy of KRN330 in combination with irinotecan after first-line or adjuvant FOLFOX (5-fluorouracil, leucovorin, and oxaliplatin)/CapOx (capecitabine and oxaliplatin) treatment failure in patients with metastatic colorectal cancer.
Measuring tumor response to treatment based on computed tomography (CT) and/or magnetic resonance imaging (MRI) has been a widely debated issue (response criteria in solid tumors [RECIST] and World Health Organization criteria). Furthermore, early identification of nonresponding patients is of great importance because the rates of response of common malignant solid tumors to chemotherapy are in the range of only 20-30%. Therefore, quantitative imaging of tumor metabolism with 18F-FDG PET/CT may provide important advantages and thus reduce side effects and costs of ineffective therapy. However, the evidence to date for the use of 18F-FDG-PET/CT with this indication is limited. The purpose of the present trial is to determine the impact of 18F-FDG PET/CT in the management of advanced colorectal cancer. The aim is also to confirm whether a metabolic response can be used as a surrogate end point in monitoring treatment response in this cancer type. The study consists of 40 patients with advanced colorectal cancer patients. All patients will be studied with 18F-FDG PET/CT combined with diagnostic contrast enhanced abdominal CT before the start of chemotherapy and re-evaluated 4-5 weeks after the initiation of therapy. Effect of this metabolic and anatomic change in therapy are evaluated and correlated to survival, morbidity, and treatment -related costs. Histopathologic confirmation of response is evaluated whenever possible. The data will be collected between 2008 and 2012.
This is a multi-center, 2-part phase 1b/2 study of AMG 655 in combination with AMG 479 to be conducted in the United States and Spain. Part 1 is a dose escalation segment to identify a dose of AMG 655 in combination with AMG 479 that is safe and tolerable. Part 2 will evaluate the safety and estimate the efficacy of AMG 655 at the dose selected in Part 1 in combination with AMG 479 for the treatment of patients with advanced NSCLC (non-squamous histology; squamous histology), CRC, pancreatic cancer, ovarian cancer, and sarcoma.
