Active clinical trials for "Retinoblastoma"

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.

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.

The purpose of this study is to compare the RetCam (Clarity Medical Systems, Pleasanton, CA) to a new prototype pediatric imaging system, COSMOS, produced by Phoenix Clinical Incorporated (PCI) (Pleasanton, CA).

This is a Phase I trial with new experimental drugs such as simvastatin in combination with topotecan and cyclophosphamide in the hopes of finding a drug that may work against tumors that have come back or that have not responded to standard therapy. This study will define toxicity of high dose simvastatin in combination with topotecan and cyclophosphamide and evaluate for cholesterol levels and IL6/STAT3 pathway changes as biomarkers of patient response.

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.

The purpose of this study is to find out how often hearing loss occurs in patients with retinoblastoma after receiving treatment with intra-arterial carboplatin.

This study will evaluate a uniform chemotherapy protocol for nonmetastatic extraocular retinoblastoma

This is a dose-escalation study aimed to assess the toxicity (and marginally the activity) of periocular topotecan in patients with relapsed-resistant retinoblastoma.

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.

Retinoblastoma is an unusual cancer of early childhood involving tumor is both eyes or, in certain circumstances, one eye only. This condition is the result of an abnormal gene which makes both retinas (the back of the eye) vulnerable to develop multiple tumors. Growths in the eye impair vision temporarily or permanently. These tumors are malignant, which means that they can grow within the eye, spread outside of the eye, and be fatal if untreated. Standard therapy for bilateral retinoblastoma includes removal of one eye if vision cannot be save and radiation treatment of either eye in which vision might be saved. Radiation controls tumor growth in the majority of cases. Another standard method is cryotherapy (freezing a tumor to kill it). Chemotherapy (medicines used to kill tumor cells) has been used in the past for tumor in or outside the eye, but is not standard. Hyperthermia, increasing the temperature of a tumor to kill it, is widely performed, and can be done to a retinoblastoma tumor by a laser; this method is not standard. The problem with removal of an eye is that any hope of vision is lost. The problems with radiation include incomplete control of tumor, injury to the eye or surrounding tissue with decreased growth, and that (due to the abnormal retinoblastoma gene) children are very susceptible to develop other tumors, especially in the tissue which was given radiation. The doctors at Children's Memorial Hospital are using a newer form of treatment, including laser hyperthermia, chemotherapy and cryotherapy to decrease retinoblastoma tumors. Some may be controlled indefinitely, reducing the number of eyes that need radiation or removal. OBJECTIVES To find out how well chemotherapy plus cryotherapy and laser hyperthermia work on retinoblastoma tumors. To find out whether vision can be saved and tumors controlled without radiation or removal of the eye.
