Filter by:This single site, single-arm, non-randomized, dose escalation phase I toxicity clinical trial will assess primarily the safety and secondarily the efficacy of episcleral topotecan in patients with active residual or recurrent intraocular retinoblastoma in at least one eye following completion of first-line therapy.
As the survival of children with retinoblastoma in high income countries is higher than 95% including the bilateral forms this study hopes to improve the outcome in low income countries in Africa by improving early diagnosis and early implementation of this protocol of therapeutic recommendations for treatment.
The purpose of this study is to evaluate different sutures for orbital implants in retinoblastoma patients.
Retinoblastoma is the most common pediatric eye malignancy and manifests between 1 and 5 years of age. The tumor is most often diagnosed by leukocoria ( white reflex in the pupil). There is often a significant delay in diagnosis and early diagnosis enables good life prognosis and better vision outcome.There is currently not a standardized screening protocol for detection of retinoblastoma. Vision screening methods are recommended for children 3-5 years of age. The investigators are attempting to use instrument based screening started from birth to detect leukocoria.
Children with retinoblastoma who may benefit from intra-arterial chemotherapy will receive up to 3 doses of melphalan and will be assessed for feasibility, toxicity, and response.
Rationale: Individuals with a cancer predisposition due to a mutation in the paradigm tumor suppressor gene RB1, have a high risk to develop the childhood cancer retinoblastoma (Rb). Biopsies are not possible in Rb, before treatment selection. Heritable Rb patients have also a high risk to develop other types of second primary, either childhood or adult, malignancies (SPMs), notably sarcomas and melanomas. Remarkably, SPMs are now the leading cause of death in heritable-Rb-survivors. Unfortunately, there are no well-developed regular surveillance protocols for SPMs in Rb survivors available right now. Recently, new non-invasive cancer test have been developed, based on either RNA-sequencing data from platelets (ThromboSeq), or on extracellular membrane vesicles (EVs) derived from tumor cells present in blood. Objective: - Determine the non-cancerous baseline in adult RB1-mutation carriers (heritable-Rb-survivors). - Contribute to the biobanking of blood and cancerous tissues from RB1-mutation carriers with SPMs. - The development of blood-based tests, either platelet or EV-based, for the detection of (the type of) tumors in RB1-mutation carriers. Study design: Cross-sectional multicenter trial. Study population: - 40 Rb patients (children), - 40 controls (children), - 153 Rb survivors (adults), - 153 controls (adults), - 10 Rb survivors with SPM (children/adults). Main study parameters/endpoints: - Determine the non-cancerous baseline in adult RB1-mutation carriers (heritable-Rb-survivors). - Contribute to the biobanking of blood and cancerous tissues from RB1-mutation carriers with SPMs. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Two blood samples totalling 10ml blood will be collected for every participant. Additionally, a short questionnaire has to be filled in concerning their and their family's cancer history. Blood draws will be done, when participants are already present in the hospital for other appointments, and thus no extra visits are required. For all children, blood will be collected through an already present IV, and so no extra venepuncture is required. Children have to be included because Rb is a tumor only present in this patient group.
This single-arm, non-randomized, dose escalation phase I clinical trial will assess primarily the safety and secondarily the efficacy of episcleral topotecan in patients with active de novo or recurrent intraocular retinoblastoma in at least one eye following completion of first-line therapy.
Retrospective review of 5-year long term outcomes of superselective intra-arterial chemotherapy treatment in retinoblastoma in a single institute. The treatment outcomes, globe salvage rates and complications of superselective intra-arterial chemotherapy both for treating naive patients (primary treatment group) and for patients who received systemic chemotherapy previously (secondary treatment group) were evaluated.
This trial studies health outcomes after treatment in patients with retinoblastoma. Gathering health information over time from patients and family members through vision assessments, samples of tissue and saliva, and questionnaires may help doctors learn more about what causes retinoblastoma, identify long-term health outcomes for patients with retinoblastoma, and find out which therapies may be the best for treating 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.
