Filter by:To assess the efficacy of methotrexate in a genetically selected population of patients with advanced colorectal cancer, who have loss of a particular gene, MSH2. The efficacy of methotrexate will be evaluated by the proportion of cases that have a significant response to treatment (objective response rate).
The purpose of this interventional study is to investigate whether there is evidence that panitumumab in combination with XELOX (capecitabine plus oxaliplatin) chemotherapy will safely increase progression-free survival, above that of XELOX alone in subjects with KRAS wild-type metastatic colorectal cancer who have not responded to or progressed after first line therapy with irinotecan and a fluoropyrimidine. Further Objectives Exploratory objectives may include investigation of potential correlations between the treatment regimen and epidermal growth factor receptor (EGFR) expression, detection of the functional genetic polymorphisms of the EGFR gene, EGFR gene amplification (FISH), EGFR downstream protein and gene expression parameters, proteomics and epigenetics.
This trial is designed as a phase II evaluation of the effect of CY-503 or placebo on progression free survival (PFS) defined as the time from start of treatment until the objective observation of progressive disease (PD) or death from any course in patients with chemotherapy-refractory metastatic colorectal cancer.
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.
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.
The purpose of this study is to determine whether sorafenib in combination with chemotherapy has a positive effect on time to progression of the tumor or death for the treatment of large bowel cancer that has already progressed during a first chemotherapy.
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.
This phase 0 trial is studying whether 2 weeks of cetuximab and dasatinib will change tumor cells in patients with colorectal cancer and liver metastases that can be removed by surgery. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
