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 tumor cells from dividing so they stop growing or die. Combining radiation therapy with chemotherapy may kill more tumor cells. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy plus radiation therapy with radiation therapy alone in treating patients with early-stage Hodgkin's disease.
RATIONALE: Palliative chemotherapy may help patients with advanced colorectal cancer live longer and more comfortably. PURPOSE: Randomized phase III trial to compare the effectiveness of and quality of life following three different palliative chemotherapy regimens in treating patients with advanced metastatic or recurrent colorectal cancer.
RATIONALE: Interferon alfa may interfere with the growth of cancer cells. Low doses of interferon alfa may be as effective as high doses. PURPOSE: Randomized phase III trial to compare the effectiveness of low-dose or high-dose interferon alfa in treating patients who have newly diagnosed chronic myelogenous leukemia.
RATIONALE: Radiation therapy may kill any tumor cells remaining after surgery. PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared to no further therapy in treating women with stage I, stage II, or stage III breast cancer that has been surgically removed.
RATIONALE: Patients with xeroderma pigmentosum are more likely to develop skin lesions in sun-affected areas. These skin lesions, such as actinic keratoses, can develop into skin cancer. T4N5 liposome lotion may reduce actinic keratoses or other sun-induced skin damage in patients with xeroderma pigmentosum. PURPOSE: Randomized double-blinded phase III trial to compare treatment using T4N5 liposome lotion with treatment using placebo in reducing actinic keratoses and other sun-induced skin damage in patients with xeroderma pigmentosum.
RATIONALE: Interferon alfa may interfere with the growth of cancer cells. It is not known whether giving high-dose or low-dose interferon alfa is more effective than no further therapy in treating patients with stage III melanoma. PURPOSE: Randomized phase III trial to compare the effectiveness of high- or low-dose interferon alfa with that of no further therapy following surgery in treating patients who have stage III melanoma.
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 intravenous infusion or intrahepatic infusion of fluorouracil and leucovorin in treating patients with colorectal cancer metastatic to the liver.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: Randomized phase III trial to compare the effectiveness of different treatment regimens in treating patients who have 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. It is not yet known which combination chemotherapy regimen is most effective in treating older patients with multiple myeloma. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without cyclophosphamide and prednisone in treating older patients with multiple myeloma.
The International Breast Cancer Intervention Study I (IBIS-I) was designed to investigate the use of tamoxifen in preventing breast cancer in women with a higher risk of developing the disease. Recruitment of women to IBIS-I ended in March 2001 and it recruited 7154 women from 36 centres in 9 countries. The results of the study showed that tamoxifen reduced the incidence of breast cancer by one third in these high risk women but with some serious side effects. IBIS-II was designed to continue the work started in IBIS-I by examining the role of anastrozole in the prevention of breast cancer which we hope will reduce breast cancer by even more than tamoxifen with less serious side effects.
