There are about 2656 clinical studies being (or have been) conducted in Puerto Rico. 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. It is not yet known which regimen of combination chemotherapy is most effective for lymphoblastic lymphoma. PURPOSE: This randomized phase III trial is studying different regimens of combination chemotherapy to compare how well they work in treating children or adolescents with newly diagnosed stage III or stage IV lymphoblastic lymphoma.
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 docetaxel and gemcitabine in treating patients who have progressive regional or metastatic bladder cancer.
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 combining oxaliplatin with fluorouracil and leucovorin in treating patients who have recurrent or metastatic cancer of the esophagus or stomach.
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. Combining more than one chemotherapy drug with radiation therapy may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy combined with radiation therapy in treating patients who have metastatic rhabdomyosarcoma or sarcoma.
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 chemotherapy regimen is more effective for cervical cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of three different chemotherapy regimens in treating patients with stage IVB, recurrent, or persistent cervical cancer.
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. Chemoprotective drugs such as dexrazoxane may protect normal cells from the side effects of chemotherapy. PURPOSE: Phase III trial to study the effectiveness of three combination chemotherapy regimens plus dexrazoxane in treating patients who have newly diagnosed nonmetastatic osteosarcoma.
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. Combining more than one drug with radiation therapy may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of vincristine plus etoposide and radiation therapy in treating children who have newly diagnosed brain stem glioma.
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using raloxifene and tamoxifen may fight breast cancer by blocking the uptake of estrogen by the tumor cells. PURPOSE: Randomized double-blinded clinical trial to compare the effectiveness of raloxifene with that of tamoxifen in preventing breast cancer in postmenopausal women.
RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining monoclonal antibody therapy with chemotherapy may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of the monoclonal antibody trastuzumab plus carboplatin and paclitaxel in treating patients who have advanced non-small cell lung cancer.
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. PURPOSE: Phase II trial to study the effectiveness of docetaxel plus carboplatin in treating patients who have advanced cancer of the esophagus.
