Filter by:The investigators are testing subtenon carboplatin in combination with vincristine and topotecan given by vein in the hopes of finding a drug combination that may be effective against retinoblastoma that has come back (recurrent) or is resistant to other treatment (refractory). The goals of this study are: - To decide if the drug combination is a useful treatment for recurrent or refractory retinoblastoma - To test the safety of the drug combination and to see what kind of effects (good and bad) can be expected from the drug combination - To measure visual changes before and after the study therapy - To use a special MRI scan to measure brain function involved in vision processing, both before and after the study therapy In this study, the investigators are also testing a new experimental way of giving carboplatin "subtenon carboplatin". The carboplatin will be given directly in the eye through a needle placed under the covering of the eye. This is to try to get more carboplatin to the retinoblastoma inside the eye.
Retinoblastoma is a cancer of the eye that occurs exclusively in children. The treatment for retinoblastoma may include surgery, chemotherapy, radiation and local treatments to the eye such as freezing (cryotherapy) and local radiation (brachytherapy). In some cases, a child with retinoblastoma will have active cancer in a single remaining eye with useful vision. In such cases, it is sometimes necessary to remove this eye. In such cases, the injection of chemotherapy directly into the artery that supplies the eye and the tumor may lead to regression of the tumor without the need to remove the eye. This form of treatment was pioneered by a group in New York (Abramson et al). In this study the investigators will assess the efficacy and safety of the technique in a group of children with retinoblastoma.
Conventional treatments of retinoblastoma involves laser photocoagulation, cryotherapy (freezing of the tumor), plaque radiotherapy,external beam radiotherapy, and intravenous chemotherapy. Enucleation (removing of the eye)is the last option when the tumor cannot be controlled otherwise. However,many children with retinoblastoma present with advanced intraocular disease for which enucleation is the only option. Intra-arterial chemotherapy (Chemosurgery)delivers anti-tumor drug directly into the ophthalmic artery (the artery feeding the eye) in order to increase the dose of drug reaching the tumor while minimizing toxicity to the rest of the body.
This laboratory study is collecting and storing tissue, blood, and bone marrow samples from young patients with cancer. Collecting and storing samples of tissue, blood, and bone marrow from patients with cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer.
The purpose of this study is to determine whether an increase in the dose of carboplatin in treatment of advanced intraocular (group C and D) retinoblastoma helps in avoiding radiotherapy and improves the rate of globe salvage.
Over the past 15 years, intravenous chemotherapy has become the most popular conservative (eye-saving) method for retinoblastoma treatment because it is often effective and usually safe. In recent years, there has been much interest in providing highly focused (focal) chemotherapy to a diseased organ including the liver, brain, and eye. With focused chemotherapy, the chemotherapy drugs are injected directly into the ophthalmic artery (the artery that supplies blood to the eye). A benefit of focal chemotherapy delivery is that it decreases the chance of toxicity to other organs such as bone marrow suppression (causing low blood counts) and the development of other cancers in the future.
This phase II trial is studying the side effects and how well cixutumumab works in treating patients with relapsed or refractory solid tumors. Monoclonal antibodies, such as cixutumumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them.
Retinoblastoma is a childhood tumor of the retina that affects approximately 1 in 18,000 children. Retinoblastoma is more prevalent in Central America, where most patients present with advanced intraocular and extraocular disease. Therefore, we have formed collaboration with Central American investigators to provide us with frozen retinoblastoma tumors from patients undergoing routine enucleation. The objective of this protocol is to begin to identify the mutations and gene expression changes that occur in retinoblastoma cells following RB1 gene inactivation in order to more effectively target chemotherapy for treating bilateral retinoblastoma.
This laboratory study is looking at genetic mutations and environmental exposure in young patients with retinoblastoma and in their parents and young healthy unrelated volunteers. Gathering information about gene mutations and environmental exposure may help doctors learn more about the causes of retinoblastoma in young patients.
The purpose of this study is to find out about the quality of life and health in a group of adults who had retinoblastoma when they were children. By quality of life, we mean how you are feeling about being satisfied with things in your life, including your physical health, your emotional health, and your ability to carry out daily activities. We hope that this information will help us provide better care to future children with retinoblastoma and better follow-up care for survivors of retinoblastoma.
