There are about 25435 clinical studies being (or have been) conducted in United Kingdom. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
RATIONALE: Diagnostic procedures, such as breast duct endoscopy, may improve the ability to detect breast cancer earlier and plan more effective treatment. PURPOSE: This phase II trial is studying how well breast duct endoscopy works in assessing cellular atypia (abnormal cells) in the breast ducts of women with a genetic risk for breast cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving combination chemotherapy before surgery may shrink the tumor so it can be removed during surgery. Giving more chemotherapy after surgery may kill any remaining tumor cells. It is not yet known which chemotherapy regimen after surgery is most effective in treating Wilm's tumor. PURPOSE: Phase III trial to study the effectiveness of chemotherapy before and after surgery in treating children who have Wilm's tumor.
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. It is not yet known which regimen of combination chemotherapy is more effective in treating esophageal cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of two regimens of combination chemotherapy in treating patients who are undergoing surgery for esophageal cancer.
RATIONALE: Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. Combining chemotherapy with peripheral stem cell transplant may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Combining isotretinoin and monoclonal antibodies may kill any remaining tumor cells following surgery. It is not yet known which treatment regimen is more effective in treating neuroblastoma. PURPOSE: This randomized phase III trial is studying how well combination chemotherapy with or without filgrastim before surgery, high-dose chemotherapy, and radiation therapy followed by isotretinoin with or without monoclonal antibody work in treating patients with neuroblastoma.
OBJECTIVES: I. Document the clinical course of severe chronic neutropenia (SCN). II. Monitor and assess long term safety of primary treatment in SCN patients in the United States, Canada, Europe, and Australia. III. Study the incidence and outcome of adverse events such as osteoporosis, splenomegaly, cytogenetic abnormalities, myelodysplastic syndrome, and leukemia. IV. Evaluate growth and development and hematologic parameters. V. Monitor for clinically significant changes in primary treatment response over time. VI. Establish a physician network to increase the understanding of SCN. VII. Establish a demographic database to allow for future research.
RATIONALE: Surgery may be an effective treatment for neuroblastoma. PURPOSE: This phase II trial is studying how well surgery works in treating patients with neuroblastoma.
