Filter by:This study will be carried out in children with diagnosis of cancer with tumors known to express N-glycolylated gangliosides. The disease must be resistant to conventional therapy. The acute toxicity and immune response will be evaluated. The expression of N-glycolylated gangliosides in tumors has previously been investigated in the tumor sample bank at this Hospital. The expression of N-glycolyl GM3 was shown in neuroblastoma, Ewing's sarcoma, Wilm's tumor and retinoblastoma. Gliomas and the aforementioned tumor types have a very bad prognosis when conventional treatment is ineffective. New therapeutic strategies have thus been examined, and several immunotherapeutic approaches, including dendritic cell vaccines, peptide vaccines and anti-idiotype vaccines are currently being assessed. Racotumomab is an anti-idiotype antibody capable of inducing anti-N-glycolyl GM3 antibodies in patients with melanoma, breast cancer and lung cancer. Dose escalation studies have shown the safety of racotumomab in the 0.5 to 2 mg dose range. The 1 mg dose level was selected for the ensuing clinical studies. This clinical trial in children involves three dose levels: 0.15 mg, 0.25 mg and 0.4 mg, owing to the difference in body surface between an adult (1.73 sq. m in average) and the candidate population for this study (0.55 to 0.7 sq. m).
Retinoblastoma treatment has become more and more focused in the last years. New treatments developed by Dr. Kaneko from Japan in 1995 are now being tested in clinical trials. Intra-arterial chemotherapy with Melphalan has shown success in some patients but with limited response when there is marked vitreal seeding. For these cases Intravitreal injections of Melphalan have been successful in Japan. In this study the same chemotherapy (melphalan) will be administered intravitreally (directly through the eye wall) and the response (short and long term) will be monitored.
This is a standard of care treatment guideline for high risk or relapsed solid tumors or CNS tumors consisting of a busulfan, melphalan, thiotepa conditioning (for solid tumors) or carboplatin and thiotepa conditioning (for CNS tumors) followed by an autologous peripheral blood stem cell transplant. For solid tumors, if appropriate, disease specific radiation therapy at day +60. For CNS tumors, the conditioning regimen and autologous peripheral blood stem cell transplant will be given for 3 cycles.
This study will test if giving topotecan directly into the blood vessel of the eye will improve the treatment of retinoblastoma. This method is referred to as "selective intra-ophthalmic artery chemotherapy" (SIOAC). The goals of this study are: - To find out if topotecan is an effective treatment for retinoblastoma when delivered directly to the ophthalmic artery (SIOAC delivery) - To find out what kind of effects (good and bad) can be expected when topotecan is given by SIOAC - To assess visual pathway function before and after the study therapy - To learn more about the pharmacology (how your body handles the drug) of topotecan when delivered directly to the ophthalmic artery
For selected cases with advanced Retinoblastoma (RTB) intraocular involvement(stage V of the Reese-Ellsworth classification) in which enucleation would usually be the standard therapeutic approach, in this project the investigators propose an alternative conservative treatment using intra-arterial chemotherapy with melphalan, via direct administration by catheterization of the ophthalmic artery.
The best treatment for recurrent cancers or those that do not respond to therapies is not known. Typically, patients with these cancers receive a combination of cancer drugs (chemotherapy), surgery, or radiation therapy. These treatments can prolong their life but may not offer a long-term cure. This study proposes using a drug called Sirolimus in combination with common chemotherapy drugs to treat patients with recurrent and refractory solid tumors. Sirolimus has been found to inhibit cell growth and to have anti-tumor activity in pediatric solid tumors in previous studies and, therefore, has the potential to increase the effectiveness of the chemotherapy drugs when given together. This study wil investigate the highest dose of Sirolimus that can be given orally with other oral chemotherapy drugs. Cohorts of 2 subjects will be started at the minimum dose. The dose will be increased in the next 2 subjects as long as there were no major reactions in the previous groups. This study will also seek to learn more about the side effects of sirolimus when used in this combination and what effects the drug has on the white cells and the immune system. Successful use of this drug will impact the cancer population greatly by providing an increased chance of survival to those with resistant or recurrent cancers.
The purpose of this study is to show that chemotherapy delivered directly through the artery supplying the eye (ophthalmic artery) to patients with retinoblastoma is a safe and effective treatment alternative to conventional systemic chemotherapy, external beam radiation, and surgical removal of the eye.
Phase II study of selective intra-arterial infusion of chemotherapy for intraocular retinoblastoma
Background: - Laboratory investigators who are studying common childhood cancers are interested in developing a tissue repository to collect and store blood, serum, tissue, urine, or tumors of children who have cancer or adults who have common childhood cancers. To develop this repository, additional samples will be collected from children and adults who have been diagnosed with common childhood cancers such as leukemia and tumors of the central nervous system. Objectives: - To collect and store blood, serum, tissue, urine, or tumor samples of children who have cancer or adults who have common childhood cancers. Eligibility: - Individuals who have been diagnosed with a common childhood cancer (e.g., leukemia) regardless of patient age. - Children, adolescents, and adults who have been diagnosed with a type of cancer more commonly found in adults. Design: - Extra blood, serum (the liquid part of blood), tissue, urine, or tumor samples will be collected from participants at a time when sampling is required for medical care or as part of a research study. - No additional procedures will be performed for the sole purpose of obtaining additional tumor tissue, aside from what is required for clinical care.
RATIONALE: Seneca Valley virus-001 may be able to kill certain kinds of tumor cells without damaging normal cells. Adding low dose cyclophosphamide (in part B of study) may help to kill even more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of Seneca Valley virus-001 in treating young patients with relapsed or refractory neuroblastoma, rhabdomyosarcoma, or rare tumors with neuroendocrine features.
