There are about 3194 clinical studies being (or have been) conducted in Portugal. 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 more than one drug, and giving them before surgery, may shrink the tumor so that it can be removed during surgery. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy followed by surgery in treating infants who have newly diagnosed neuroblastoma.
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: Phase II trial to study the effectiveness of different combination chemotherapy regimens in treating infants who have newly diagnosed neuroblastoma.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving a chemotherapy drug before surgery may shrink the tumor so that it can be removed during surgery. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy followed by surgery in treating infants who have newly diagnosed neuroblastoma.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving chemotherapy drugs before surgery may shrink the tumor so that it can be removed during surgery. PURPOSE: Phase III trial to determine the effectiveness of combination chemotherapy given before surgery in treating children who have localized neuroblastoma.
RATIONALE: Biological therapies such as BCG use different ways to stimulate the immune system and stop tumor cells from growing. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with biological therapy may kill more tumor cells. It is not yet known if BCG is more effective with or without mitomycin. PURPOSE: Randomized phase II trial to compare the effectiveness of BCG plus mitomycin with that of BCG alone in treating patients who have bladder 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 paclitaxel in treating patients who have refractory or recurrent endometrial 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 liposomal lurtotecan in treating patients who have metastatic or locally recurrent head and neck cancer.
RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Currently patients with breast cancer are treated with one of several very similar combinations of drugs. Analysis of biomarkers in tumor tissue may help doctors predict how well patients with breast cancer will respond to treatment and help doctors choose the best drug regimen to treat each patient. PURPOSE: This randomized phase III trial is studying giving different regimens of chemotherapy and comparing how well they work in treating women with large operable or locally advanced or inflammatory breast cancer. This study is also looking at whether analyzing a specific biomarker (p53) in tumor tissue may help doctors predict how well patients will respond to treatment and help doctors choose the best drug to treat each patient.
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 E7070 in treating patients who have stage IV melanoma.
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 paclitaxel in treating patients who have locally advanced, metastatic, or recurrent cancer of the vulva.
