Filter by:The purpose of the study was to determine if treating a limited volume of normal tissue surrounding the tumor or tumor bed using conformal radiation therapy would achieve similar rates of disease control compared to standard radiation therapy. The study was also conducted to examine the effect of irradiation on neurological, endocrine and cognitive function.
Studies have provided evidence that residual microscopic malignant cells in autologous bone marrow or blood stem cell grafts can contribute to posttransplant relapse. Researchers are currently exploring different methods in an attempt to purify or "purge" the stem cell product to minimize the risk of tumor contamination. The CD133+ antigen is a protein contained on or "expressed" on numerous cells in the human body including specific hematopoietic progenitor (blood forming) cells. However, this antigen is not expressed on certain cancer cells including neuroblastoma. A technique using the investigational CliniMACS cell sorting device has been developed in an effort to filter out only those stem cells that express this CD133+ antigen in order to infuse a hematopoietic stem cell product with no tumor contamination potential. The primary objective of this study is to establish safety of treating patients with a high dose chemotherapy regimen of Busulfan and Melphalan followed by autologous CD133+ hematopoietic stem cell support. Transplants recipients are expected to achieve engraftment as defined by an absolute neutrophil count of greater than or equal to 500/mm3 for three consecutive days by day 42-post infusion. Thus, safety of the treatment plan will be evaluated in terms of failure to engraft by this specific time period.
RATIONALE: Cyproheptadine and megestrol may improve appetite and help prevent weight loss in children with cancer. PURPOSE: This phase II trial is studying how well cyproheptadine and megestrol work in improving appetite and preventing weight loss in children with cachexia caused by cancer or cancer treatment.
RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Giving a chemotherapy drug before surgery may shrink the tumor so that it is no longer present by conventional imaging and tumor markers from serum and cerebrospinal fluid. Radiation therapy uses high-energy x-rays to damage tumor cells. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Combining different types of therapy may kill more tumor cells. PURPOSE: This Phase II trial is studying how well neoadjuvant chemotherapy with or without surgery and with or without high dose chemotherapy and peripheral stem cell transplantation, can increase response rates prior to radiation therapy and increase progression free and overall surviving patients with newly diagnosed intracranial germ cell tumors.
RATIONALE: Electroacupuncture may help to reduce or prevent delayed nausea and vomiting in patients treated with chemotherapy. PURPOSE: This randomized clinical trial is studying the effectiveness of electroacupuncture in treating delayed nausea and vomiting in patients who are receiving chemotherapy for newly diagnosed childhood sarcoma, neuroblastoma, nasopharyngeal cancer, germ cell tumors, or Hodgkin 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. 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: 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 I trial to study the effectiveness of combination chemotherapy plus radiation therapy in treating patients with newly diagnosed brain stem glioma.
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 radiation therapy with chemotherapy may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of etoposide plus radiation therapy followed by combination chemotherapy in treating children with newly diagnosed advanced medulloblastoma.
RATIONALE: Drugs used in chemotherapy, such as carboplatin and vincristine, 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. Combining carboplatin and vincristine with radiation therapy followed by adjuvant chemotherapy may kill more tumor cells. PURPOSE: Randomized phase II trial to study the effectiveness of combination chemotherapy plus radiation therapy followed adjuvant chemotherapy in treating young patients who have newly diagnosed high-risk CNS embryonal tumors.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctors to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy plus peripheral stem cell transplantation in treating infants with malignant brain or spinal cord tumors.
