There are about 9403 clinical studies being (or have been) conducted in Switzerland. 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: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. It is not yet known whether chlorambucil is more effective than observation in treating low-grade lymphoma of the stomach. PURPOSE: Randomized phase III trial to compare the effectiveness of chlorambucil with that of no further therapy following anti-Helicobacter therapy in treating patients with low-grade lymphoma of the stomach.
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: Phase III trial to study the effectiveness of combination chemotherapy in treating children who have Down syndrome and myeloproliferative disorder, acute myelogenous leukemia, or myelodysplastic syndrome.
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 combination chemotherapy regimen is more effective in treating advanced non-small cell lung cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of three different combination chemotherapy regimens in treating patients who have advanced non-small cell lung cancer.
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 radiation therapy with chemotherapy may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of etoposide plus radiation therapy followed by combination chemotherapy in treating children with newly diagnosed advanced medulloblastoma.
Phase I trial to study the effectiveness of raltitrexed in treating children with refractory acute leukemia. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die
RATIONALE: Diagnostic imaging procedures, such as radiolabeled monoclonal antibodies, may improve the ability to detect the residual disease in patients who have been treated for non-Hodgkin's lymphoma. PURPOSE: Phase II/III trial to study the effectiveness of monoclonal antibodies in detecting residual disease in patients who have been treated for non-Hodgkin's lymphoma.
RATIONALE: Diagnostic imaging procedures using radiolabeled monoclonal antibodies may improve the ability to detect and stage non-Hodgkin's lymphoma. PURPOSE: Phase III trial to study the effectiveness of a radiolabeled monoclonal antibody in the detection and staging of patients with non-Hodgkin's lymphoma.
RATIONALE: Questionnaires that measure quality of life may improve the ability to plan treatment for patients who have cancer of the esophagus. PURPOSE: This clinical trial studies quality-of-life assessments of patients with cancer of the esophagus who are receiving treatment.
RATIONALE: Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. It is not yet known which treatment regimen is more effective for lymphoma. PURPOSE: Randomized phase III trial to compare the effectiveness of different regimens of rituximab in treating patients who have follicular or mantle cell lymphoma.
RATIONALE: Vaccines may help the body build an immune response to kill tumor cells. PURPOSE: Randomized phase III trial to compare the effectiveness of vaccination with monoclonal antibody BEC2 and BCG with that of no further therapy in treating patients who have limited-stage small cell lung cancer.
