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 tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of vinorelbine in treating children with recurrent or refractory 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 idarubicin and cladribine in treating children who have recurrent acute myeloid leukemia.
RATIONALE: Surgery alone may be effective in treating children with neuroblastoma. PURPOSE: Phase III trial to study the effectiveness of surgery alone in treating children who have 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. Combination chemotherapy plus surgery may be an effective treatment for neuroblastoma. PURPOSE: This phase III trial is studying how well combination chemotherapy followed by surgery works in treating young patients with neuroblastoma.
RATIONALE: Drugs used in chemotherapy work in 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 whether chemotherapy is more effective with or without radiation therapy in treating patients who have rhabdomyosarcoma. PURPOSE: Phase III trial to compare the effectiveness of chemotherapy with or without radiation therapy in treating patients who have newly-diagnosed rhabdomyosarcoma.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell transplantation may allow doctors to give higher doses of chemotherapy and kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy followed by peripheral stem cell transplantation in treating children who have recurrent or refractory Hodgkin's lymphoma or non-Hodgkin's lymphoma.
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. Combining radiation therapy with chemotherapy may kill more tumor cells. It is not yet known which chemotherapy regimen is more effective when combined with radiation therapy for treating medulloblastoma. PURPOSE: Randomized phase III trial to compare two combination chemotherapy treatments plus radiation therapy in treating children with newly diagnosed medulloblastoma.
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, surgery, and radiation therapy in treating children who have advanced soft tissue 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 cancer cells. It is not yet known which chemotherapy regimen is more effective for metastatic colorectal cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of intrahepatic floxuridine, leucovorin, and dexamethasone with that of systemic fluorouracil and leucovorin in treating patients who have unresectable liver metastases from colorectal cancer.
Phase I trial to study the effectiveness of topotecan in treating children with refractory leukemia. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die.
