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. 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 use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known if chemotherapy is more effective with or without radiation therapy in treating brain metastases. PURPOSE: Randomized phase III trial to compare the effectiveness of chemotherapy with or without radiation therapy to the brain in treating patients who have stage IV melanoma with asymptomatic brain metastases.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. It is not yet known which chlorambucil regimen is more effective in treating advanced chronic lymphocytic leukemia. PURPOSE: Randomized phase III trial to determine the effectiveness of different regimens of chlorambucil in treating patients who have advanced chronic lymphocytic leukemia.
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.
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 glufosfamide in treating patients who have recurrent glioblastoma multiforme.
The purpose of this study is to compare the effectiveness of treatment with BMS-232632 to that of efavirenz (EFV) when both are used with zidovudine (ZDV) and lamivudine (3TC).
This 2 arm study will compare the safety and efficacy of oral Xeloda, or 5-fluorouracil in combination with leucovorin, in patients who have undergone surgery for colon cancer. Patients will be randomized to receive either Xeloda 1250mg/m2 po bid on days 1-14 every 21 days, or leucovorin 20mg/m2 iv + 5-FU 425mg/m2 iv daily from day 1 to day 5 every 28 days. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.
