There are about 13446 clinical studies being (or have been) conducted in Belgium. 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. 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 radiation therapy plus chemotherapy is more effective than radiation therapy alone in treating patients with head and neck cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of high-dose radiation therapy alone with high-dose radiation therapy plus cisplatin in treating patients with head and neck cancer who have undergone surgery to remove the cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Colony-stimulating factors such as G-CSF may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. It is not yet known whether chemotherapy and surgery plus G-CSF is more effective than chemotherapy and surgery alone in treating patients with osteosarcoma. PURPOSE: Randomized phase III trial to compare the effectiveness combination chemotherapy and surgery with or without G-CSF in treating patients who have newly diagnosed osteosarcoma.
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, giving the drugs in different ways, and combining radiation therapy and surgery with chemotherapy may kill more tumor cells. PURPOSE: Randomized phase III trial to compare radiation therapy alone before surgery with radiation therapy plus fluorouracil and leucovorin before surgery, with and without fluorouracil and leucovorin after surgery in patients with rectal cancer that can be surgically removed.
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 regimen of combination chemotherapy is more effective for acute myeloid leukemia or myelodysplastic syndrome. PURPOSE: Randomized phase III trial to compare the effectiveness of different combination chemotherapy regimens in treating children who have newly diagnosed acute myeloid leukemia or myelodysplastic syndrome.
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells and may be an effective treatment for prostate cancer. PURPOSE: Randomized phase III trial to compare radiation therapy with no further treatment in treating patients with stage III prostate cancer following radical prostatectomy.
RATIONALE: Radiolabeled monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. This may be an effective treatment for prostate cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of strontium or radiation therapy in treating patients with prostate cancer that is refractory to hormone therapy who have painful bone metastases.
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known whether receiving radiation therapy or no further therapy after surgery is more effective for cancer of the uterus. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy with that of no further therapy in treating patients who have stage I or stage II cancer of the uterus that has been surgically removed.
The purpose of this study is to see if it is safe and effective to use IM862 to treat Kaposi's sarcoma (KS) in AIDS patients.
The purpose of this study is to compare the safety and effectiveness of SCH 56592 with that of fluconazole in the treatment of OPC (a fungal infection of the throat) in HIV-positive patients.
To evaluate the effectiveness of atovaquone (566C80) compared to a standard antipneumocystis agent, (SMX/TMP), for the treatment of mild to moderate Pneumocystis carinii pneumonia (PCP) in AIDS patients. To compare the safety of short-term (21 days) treatment with 566C80 and SMX/TMP in AIDS patients with an acute episode of PCP. Standard therapies for acute treatment of PCP involve either SMX/TMP or pentamidine isetionate. Although both treatments are equally effective, side effects prevent completion of therapy in 11-55 percent of patients.
