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 tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of nitrocamptothecin in treating patients who have glioblastoma multiforme.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. It is not yet known which regimen of chemotherapy is more effective for acute lymphoblastic leukemia. PURPOSE: This randomized phase III trial is comparing four regimens of combination chemotherapy to see how well they work in treating children with newly diagnosed acute lymphoblastic leukemia.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. 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 if combination chemotherapy plus peripheral stem cell transplantation is more effective with or without rituximab for non-Hodgkin's lymphoma. PURPOSE: This randomized phase III trial is studying giving combination chemotherapy and peripheral stem cell transplantation together with rituximab to see how well it works compared to combination chemotherapy and peripheral stem cell transplantation alone in treating patients with relapsed non-Hodgkin's lymphoma.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. It is not yet known which regimen of combination chemotherapy is more effective for childhood acute lymphoblastic leukemia. PURPOSE: This randomized phase III trial is comparing different regimens of combination chemotherapy to see how well they work in treating children with acute lymphoblastic leukemia.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage cancer cells. Combining chemotherapy with radiation therapy may kill more cancer cells. It is not yet known which combination chemotherapy regimen is most effective in treating Hodgkin's lymphoma. PURPOSE: Randomized phase III trial to compare the effectiveness of different regimens of combination chemotherapy with or without radiation therapy in treating patients who have Hodgkin's lymphoma.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Chemoprotective drugs, such as dexrazoxane, may protect normal cells from the side effects of chemotherapy. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without dexrazoxane in treating children who have Hodgkin's disease.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells and prevent the spread of cancer to the brain. It is not yet known if standard-dose radiation therapy is more effective than high-dose radiation therapy in preventing the spread of limited-stage small cell lung cancer cells to the brain. PURPOSE: This randomized phase III trial is comparing two different regimens of radiation therapy to see how well they work in treating patients with limited-stage small cell lung cancer in complete remission.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one chemotherapy drug with surgery may kill more tumor cells. It is not yet known if chemotherapy followed by surgery is more effective than surgery followed by chemotherapy for stomach cancer. PURPOSE: This randomized phase III trial is studying surgery followed by combination chemotherapy to see how well it works compared to combination chemotherapy followed by surgery in treating patients with locally advanced stomach cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Hydration with a saline solution may protect kidney cells from the side effects of chemotherapy. PURPOSE: Randomized phase II trial to compare the effectiveness of glufosfamide with or without hydration in treating patients who have pancreatic cancer that is metastatic or cannot be removed by surgery.
RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. It is not yet known whether vaccine therapy is more effective than observation alone for melanoma. PURPOSE: This randomized phase III trial is studying vaccine therapy to see how well it works compared to observation alone in treating patients with primary stage II melanoma.
