There are about 243 clinical studies being (or have been) conducted in Cyprus. 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. Bicalutamide and goserelin may fight prostate cancer by reducing the production of testosterone. It is not yet known if radiation therapy is more effective with or without bicalutamide and goserelin in treating prostate cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy with or without bicalutamide and goserelin in treating patients who have localized prostate cancer.
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Radiation therapy to the brain may be effective in preventing brain metastases. It is not yet known if radiation therapy is effective following chemotherapy in preventing brain metastases. PURPOSE: Randomized phase III trial to determine the effectiveness of radiation therapy in preventing brain metastases in patients who have received chemotherapy for extensive-stage small cell lung cancer.
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.
