Active clinical trials for "Retinoblastoma"

The purpose of this study is to test the safety of the treatment combination of alternating standard chemotherapy and another (melphalan) chemotherapy at different interval schedules. Researchers want to find out what effects, good and/or bad, the treatment combination has on the patients and their retinoblastoma.

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 purpose of this trial is to evaluate proton beam radiation therapy as an alternative to external photon beam irradiation in children with retinoblastoma as a means of local tumor control and ocular retention.

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.

Primary Objectives: To investigate the response rate (complete response plus partial response) of temozolomide for 8 weeks (2 cycles), in patients with retinoblastoma metastatic to the central nervous system (mass only) in two strata: A. Initial diagnosis (mass) B. At relapse (mass) To determine hematologic toxicity: absolute neutrophil count (ANC), platelets and hemoglobin count. Secondary Objectives: To determine the response in other metastatic sites (non target) (orbit, bone marrow, bone, lung, liver and others) To determine the remission rate and time to relapse on temozolomide. To document the response of leptomeningeal metastasis (cerebrospinal fluid) to temozolomide

The purpose of this study is to find out about the quality of life and health in patients who had retinoblastoma in one eye (unilateral retinoblastoma), who either received treatment with chemotherapy injected directly into an artery leading to the eye (intra-arterial chemotherapy) or removal of the eye (enucleation). By quality of life, the investigators mean how the participants are feeling about being satisfied with things in their life, including, physical health, emotional health, and their ability to carry out daily activities. The investigators want to see if either treatment option would affect quality of life differently. The investigators hope that this information will help us provide better care to future children with retinoblastoma and better follow-up care for survivors of retinoblastoma.

To study the effectiveness and safety profiles of photodynamic therapy (PDT) for the treatment of human 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.

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.
