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.
This phase III trial is studying how well combination chemotherapy with or without radiation therapy works in treating young patients with newly diagnosed stage III or stage IV Wilms' tumor. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving more than one drug (combination chemotherapy) with or without radiation therapy may kill more tumor cells.
This phase III trial is studying vincristine, dactinomycin, and doxorubicin with or without radiation therapy or observation only to see how well they work in treating patients undergoing surgery for newly diagnosed stage I, stage II, or stage III Wilms' tumor. Drugs used in chemotherapy, such as vincristine, dactinomycin, and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors.Giving these treatments after surgery may kill any tumor cells that remain after surgery. Sometimes, after surgery, the tumor may not need additional treatment until it progresses. In this case, observation may be sufficient.
This randomized phase III trial studies the best individual therapy for women who have node-negative, estrogen-receptor positive breast cancer by using a special test (Oncotype DX), and whether hormone therapy alone or hormone therapy together with combination chemotherapy is better for women who have an Oncotype DX recurrence score of 11-25. Estrogen can cause the growth of breast cancer cells. Hormone therapy may fight breast cancer by blocking the use of estrogen by the tumor cells or by lowering the amount of estrogen the body makes. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving hormone therapy together with more than one chemotherapy drug (combination chemotherapy) has been shown to reduce the chance of breast cancer recurrence, but the benefit of adding chemotherapy to hormone therapy for women with node-negative, estrogen-receptor positive breast cancer is small. New tests may provide information about which patients are more likely to benefit from chemotherapy.
The purpose of this study is to compare the short and long term outcomes of people who have colon cancers removed either by laparotomy (a large cut in the abdominal wall) or by a laparoscopic assisted approach (keyhole surgery). This study involves 37 credentialled surgeons in 20 approved hospitals across Australasia and during the recruitment period (Jan 1998 to March 2005) 601 patients were recruited into the ALCCaS Trial.
This study is designed to evaluate the safety and antiviral activity of tenofovir disoproxil fumarate (TDF, tenofovir DF) compared to adefovir dipivoxil (ADV) for the treatment of HBeAg-positive chronic hepatitis B. Participants will receive either TDF or the approved hepatitis B therapy ADV. After 48 weeks all participants will be switched to open-label TDF.
This clinical trial is studying how well surgery and/or combination chemotherapy with or without radiation therapy or observation only work in treating young patients with newly diagnosed stage I or stage II lymphocyte predominant Hodgkin disease (LPHD). Surgery may be an effective treatment for LPHD. Drugs used in chemotherapy, such as doxorubicin, vincristine, prednisone, and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill cancer cells. Giving more than one drug (combination chemotherapy) with or without radiation therapy may kill more cancer cells.
RATIONALE: Drugs used in chemotherapy work in different ways to stop cancer cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage cancer cells. Giving combination chemotherapy together with radiation therapy may kill more cancer cells. PURPOSE: This clinical trial is studying how well giving chemotherapy together with radiation therapy works in treating patients with acute lymphoblastic leukemia that has relapsed in the CNS and/or testes.
This randomized phase III trial is studying how well standard-dose radiation therapy works compared to reduced-dose radiation therapy in children 3-7 years of age AND how well standard volume boost radiation therapy works compared to smaller volume boost radiation therapy when given together with chemotherapy in treating young patients who have undergone surgery for newly diagnosed standard-risk medulloblastoma. Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy, such as vincristine, cisplatin, lomustine, and cyclophosphamide, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving radiation therapy with chemotherapy after surgery may kill any remaining tumor cells. It is not yet known whether standard-dose radiation therapy is more effective than reduced-dose radiation therapy when given together with chemotherapy after surgery in treating young patients with medulloblastoma.
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using triptorelin, exemestane, and tamoxifen may fight breast cancer by blocking the use of estrogen. It is not yet known whether giving triptorelin together with exemestane is more effective than triptorelin and tamoxifen in treating hormone-responsive breast cancer. PURPOSE: This randomized phase III trial is studying triptorelin and exemestane to see how well they work compared to triptorelin and tamoxifen in treating premenopausal women with hormone-responsive breast cancer.
This is a Phase III study in patients with melanoma that has spread to the lymph nodes and/or a distant organ, and who have had all of their cancer surgically removed. The purpose of this study is to evaluate the ability of the CancerVax™ vaccine to prevent or slow the recurrence of melanoma.
