There are about 2459 clinical studies being (or have been) conducted in New Zealand. 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 may kill more tumor cells. PURPOSE: This randomized phase III trial is studying two different combination chemotherapy regimens and comparing how well they work in treating children with low-grade astrocytomas or other residual tumors of the brain.
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: 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 whether combination chemotherapy alone or combination chemotherapy plus radiation therapy is more effective for childhood kidney cancer. PURPOSE: Phase III trial to compare the effectiveness of combination chemotherapy with or without radiation therapy in treating children who have kidney 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. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. It is not yet known which therapy regimen is most effective for treating patients with kidney tumors. PURPOSE: Phase III trial to compare the effectiveness of chemotherapy with or without radiation therapy, surgery, and/or peripheral stem cell or bone marrow transplantation in treating young patients with kidney tumors.
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy may fight breast cancer by blocking the uptake of estrogen. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with hormone therapy may kill more tumor cells. It is not yet known which treatment regimen is more effective for breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of hormone therapy during or after combination chemotherapy or hormone therapy alone in treating perimenopausal or postmenopausal women who have stage II or stage IIIA breast cancer.
RATIONALE: Removing axillary lymph nodes may be effective in stopping the spread of breast cancer cells. It is not yet known if surgery to remove breast cancer is more effective with or without lymph node removal. PURPOSE: Randomized phase III trial to compare the effectiveness of breast surgery with or without removal of axillary lymph nodes in treating women who have stage I or stage IIA breast cancer.
