There are about 25560 clinical studies being (or have been) conducted in Germany. 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: Testosterone can stimulate the growth of cancer cells. Bicalutamide and goserelin may fight prostate cancer by reducing the production of testosterone. It is not yet known which hormone therapy regimen is most effective for prostate cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of bicalutamide with that of observation followed by bicalutamide plus either goserelin or orchiectomy for patients who have prostate 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 oxaliplatin in treating women who have advanced or metastatic breast cancer that has not responded to previous chemotherapy.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if surgery alone or surgery combined with chemotherapy is more effective in treating stomach cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of surgery with or without combination chemotherapy in treating patients who have stage II, stage III, or stage IV stomach cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy used high-energy x-rays to damage tumor cells. It is not yet know whether chemotherapy followed by radiation therapy is more effective than chemotherapy given with radiation therapy for non-small cell lung cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of two different regimens of chemotherapy and radiation therapy in treating patients who have unresectable stage I, stage II, or stage III non-small cell lung cancer.
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Adjuvant radiation therapy may kill any remaining tumor cells following surgery or radiosurgery for brain metastases. PURPOSE: This randomized phase III trial is studying surgery or radiosurgery alone to see how well it works compared to surgery or radiosurgery and whole-brain radiation therapy in treating brain metastases in patients with solid tumors.
