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: Radiation therapy uses high-energy x-rays to damage tumor cells and may be a less invasive treatment and cause fewer side effects than complete axillary lymph node dissection. It is not yet known which treatment is more effective for invasive breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of complete axillary lymph node dissection with that of axillary radiation therapy in treating women who have invasive breast cancer.
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 glufosfamide in treating patients who have recurrent glioblastoma multiforme.
The purpose of this study is to compare the effectiveness of treatment with BMS-232632 to that of efavirenz (EFV) when both are used with zidovudine (ZDV) and lamivudine (3TC).
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving chemotherapy with peripheral stem cell transplant or bone marrow transplant may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. It is not yet known whether high-dose chemotherapy plus peripheral stem cell or bone marrow transplant is more effective than chemotherapy alone in treating small cell lung cancer. PURPOSE: This randomized phase III trial is studying how well chemotherapy followed by peripheral stem cell or bone marrow transplant works compared to chemotherapy alone in treating patients with limited-stage or extensive-stage small cell lung cancer.
This 2 arm study will compare the safety and efficacy of oral Xeloda, or 5-fluorouracil in combination with leucovorin, in patients who have undergone surgery for colon cancer. Patients will be randomized to receive either Xeloda 1250mg/m2 po bid on days 1-14 every 21 days, or leucovorin 20mg/m2 iv + 5-FU 425mg/m2 iv daily from day 1 to day 5 every 28 days. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.
RATIONALE: Interleukin-2 may stimulate a person's white blood cells to kill more cancer cells. PURPOSE: Phase I trial to study the effectiveness of interleukin-2 in treating children who have undergone bone marrow transplantation for acute myeloid leukemia.
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 and shrink tumors so they can be removed during surgery. PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy before surgery in treating women who have locally advanced, inflammatory, or large surgically removable breast cancer.
RATIONALE: Drugs used in chemotherapy work in 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. It is not yet known which chemotherapy regimen combined with radiation therapy and/or surgery is more effective in treating Ewing's sarcoma or primitive neuroectodermal tumor. PURPOSE: Randomized phase III trial to compare the effectiveness of different chemotherapy regimens combined with radiation therapy and/or surgery in treating patients who have Ewing's sarcoma or primitive neuroectodermal tumor.
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 gemcitabine in treating children who have relapsed or refractory acute lymphoblastic leukemia or acute myelogenous leukemia.
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 for treating anaplastic large cell lymphoma. PURPOSE: This randomized phase III trial is studying several different regimens of combination chemotherapy to compare how well they work in treating children with anaplastic large cell lymphoma.
