Filter by: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.
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 the research study is to learn more about the causes of retinoblastoma and to identify possible risk factors in the parents of patients with retinoblastoma. This kind of study is called an epidemiology study and is often done by interviewing people with and without the disease. In the case of a childhood disease, the researchers ask about experiences of the parents and children before the disease developed.
This is a dose-escalation study aimed to assess the toxicity (and marginally the activity) of periocular topotecan in patients with relapsed-resistant retinoblastoma.
RATIONALE: Radiolabeled monoclonal antibodies, such as iodine I 131 monoclonal antibody 3F8, can find tumor cells and carry tumor-killing substances to them without harming normal cells. This may be an effective treatment for central nervous system cancer or leptomeningeal metastases. PURPOSE: This phase II trial is studying the side effects and how well iodine I 131 monoclonal antibody 3F8 works in treating patients with central nervous system cancer or leptomeningeal cancer.
Retinoblastoma is a rare pediatric ocular tumor caused by germline and/or somatic mutations in the tumor suppressor gene RB1. Survivors of retinoblastoma, particularly those with the hereditary form of the disease (germline RB1 mutations) are highly susceptible to developing additional malignancies, which are a major cause of morbidity and mortality. Since 1984, REB has followed a cohort of 2136 (including 1,995 one-year) retinoblastoma survivors to investigate the contributions of treatment and genetic risk factors to second cancer etiology. The last systematic follow-up for second cancer incidence and cause-specific mortality was completed in 2009. As the cohort ages, we now propose to conduct another interview survey to collect information on newly diagnosed second cancers. Additionally, we propose to expand collection of germline DNA for additional molecular studies in survivors. Retinoblastoma survivors have now entered adult ages when epithelial tumors would be expected to occur with greater frequency. Given that the somatic mutations in the RB1 pathway have been identified in several epithelial tumors (bladder, brain, breast, esophagus, liver, lung, prostate) in addition to sarcomas, it is important to collect new information on these epithelial tumors, and to investigate whether the previously identified high risks of sarcomas and melanoma will persist as the cohort ages. Additionally, our understanding of genetic susceptibility to second cancers is limited. Given that this is the only cohort of long-term survivors of retinoblastoma being followed in the U.S., combined with the leadership role of REB in the study of second cancers, continued follow-up of this cohort will provide unique clinical and epidemiologic data on the long-term cumulative risk of second cancers in this distinctive cohort of childhood cancer survivors.
The purpose of this study is to investigate whether the prophylactic use of itraconazole is a better option than empirical use of itraconazole in the management (prevention and treatment) of fungal infection associated with high-dose chemotherapy and autologous hematopoietic stem cell transplantation in children with high-risk solid tumor.
