There are about 25435 clinical studies being (or have been) conducted in United Kingdom. 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. Combining more than one drug may kill more cancer cells. Steroids, such as dexamethasone or prednisolone, may help relieve some of the side effects of chemotherapy. It is not yet known which regimen of chemotherapy plus steroid therapy is more effective in treating patients with multiple myeloma. PURPOSE: Randomized phase III trial to compare the effectiveness of two different regimens of chemotherapy plus steroid therapy in treating patients with multiple myeloma that has recurred for the first time.
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 combination chemotherapy regimen is more effective in treating older patients with acute myeloid leukemia. PURPOSE: Randomized phase III trial to compare the effectiveness of two different combination chemotherapy regimens in treating older patients with acute myeloid leukemia in first remission.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Bone marrow transplantation may allow doctors to give higher doses of chemotherapy drugs and kill more cancer cells. It is not yet known whether high dose chemotherapy plus bone marrow transplantation is more effective than high dose chemotherapy alone for intermediate- or high-grade non-Hodgkin's lymphoma. PURPOSE: Randomized phase III trial to compare the effectiveness of high dose chemotherapy with or without bone marrow transplantation in treating patients who have intermediate- or high-grade non-Hodgkin's lymphoma.
RATIONALE: Hormone therapy may stop the growth of cancer cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining hormone therapy with chemotherapy may kill more cancer cells. It is not yet known which hormone therapy and chemotherapy regimen is most effective for acute lymphoblastic leukemia. PURPOSE: Randomized phase III trial to compare the effectiveness of different steroid therapy and chemotherapy regimens in treating children who have acute lymphoblastic leukemia.
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 combination chemotherapy regimen is more effective for non-Hodgkin's lymphoma. PURPOSE: Randomized phase III trial to compare the effectiveness of different regimens of combination chemotherapy in treating children who have newly diagnosed non-Hodgkin's lymphoma.
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using exemestane or tamoxifen may fight breast cancer by blocking the uptake of estrogen. It is not yet known whether exemestane is more effective than tamoxifen in treating breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of exemestane with that of tamoxifen in treating postmenopausal women with primary breast cancer who have already received 2-3 years of tamoxifen following surgery.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not known whether giving chemotherapy in addition to standard therapy is a more effective treatment for lung cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of standard therapy given with or without combination chemotherapy in treating patients with 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. Giving drugs in different forms may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of doxorubicin in treating women with advanced metastatic breast cancer.
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by reducing the production of estrogen. It is not yet known if prolonged tamoxifen is more effective than shorter tamoxifen therapy following curative treatment for breast cancer. PURPOSE: This randomized phase III trial is studying giving tamoxifen over a prolonged period of time to see how well it works compared to giving tamoxifen over a shorter period of time in treating patients who have had a breast tumor removed.
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: Randomized phase III trial to compare the effectiveness of carboplatin plus vincristine in treating children and adolescents with low grade glioma.
