Filter by: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. Combining more than one drug or combining chemotherapy with surgery may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy and surgery in treating patients who have newly diagnosed metastatic osteosarcoma.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Colony-stimulating factors such as G-CSF may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. It is not yet known whether chemotherapy and surgery plus G-CSF is more effective than chemotherapy and surgery alone in treating patients with osteosarcoma. PURPOSE: Randomized phase III trial to compare the effectiveness combination chemotherapy and surgery with or without G-CSF in treating patients who have newly diagnosed osteosarcoma.
The suppression of IGF-I and growth hormone may significantly alter the pathobiology of osteosarcoma. SMS 201-955 pa LAR is a long acting analog of Somatostatin which inhibits the pituitary release of growth hormone, reducing levels of circulating IGF-I . Additional data on tamoxifen usage has also demonstrated a reduction in circulating IGF-I levels. The degree of suppression of IGF-I and growth hormone will be determined at two dose levels of SMS 291-955 pa LAR. Tamoxifen will be added to two of the cohorts to determine if the additive effects of tamoxifen and SMS 201-955 pa LAR will lead to additional reduction of circulating IGF-I and growth hormone levels. Arginine-stimulated GH tests to assess levels of growth hormone in the blood will be administered pre-treatment evaluation up to three times, one time on weeks 2, 8, 16, 28, 40, 52, and one month post last dose of SMS 201-955 pa LAR. The four cohorts for this study will receive 60 or 90 mg SMS 201-955 pa LAR injectable every four weeks for up to 52 weeks. Two of the cohorts will receive 10 mg Tamoxifen on a daily basis.
The study is designed to determine if the administration of multi-drug adjuvant chemotherapy for patients with primary non-metastatic osteogenic sarcoma, both prior to and after the definitive surgical procedure for their primary tumor is superior as a treatment strategy to the current approach of giving drugs only after the definitive surgical procedure has been performed. An effort will be made as well to determine if the administration of pre-definitive surgery, chemotherapy leads to an increase in the proportion of the patients suitable for a limb salvage primary surgical procedure.
This protocol is designed to test the feasibility of the administration of vincristine, adriamycin and cytoxan, alternating with the newly developed regimen ifosfamide VP-16 as well as the efficacy of this therapy in addition to radiotherapy in producing complete responses and disease-free survival in patients with Ewing's sarcoma, primitive sarcoma of bone, peripheral neuroepithelioma, and soft tissue sarcoma. This will not be a randomized study but will be comparable to the large data base of similar patients treated on successive Pediatric Branch studies.
