Filter by: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.
To study the clinical characteristics and treatment outcomes of patients who experienced inadvertent trauma before diagnosis of retinoblastoma.
Digital case management systems have the potential to increase compliance with protocol-driven treatment, reduce treatment abandonment and ultimately help to close the discrepancy in pediatric cancer outcomes between Low and Middle Income Countries (LMICs) and high-income countries (HICs). The investigators aim to adapt an open-source digital case management platform to incorporate standardized pediatric oncology protocols. Effectiveness will be evaluated by provider protocol compliance (primary outcome) and patient treatment abandonment rates using the digital case management system as compared to historic controls. The study population will include patients diagnosed with Burkitt lymphoma, Diffuse large B-cell lymphoma (DLBCL) or retinoblastoma at Bugando Medical Centre in Tanzania.
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.
Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.
This is a phase I, open-label, non-randomized study that will enroll pediatric and young adult research participants with relapsed or refractory non-CNS solid tumors to evaluate the safety, feasibility, and efficacy of administering T cell products derived from the research participant's blood that have been genetically modified to express a EGFR-specific receptor (chimeric antigen receptor, or CAR) that will target and kill solid tumors that express EGFR and the selection-suicide marker EGFRt. EGFRt is a protein incorporated into the cell with our EGFR receptor which is used to identify the modified T cells and can be used as a tag that allows for elimination of the modified T cells if needed. On Arm A of the study, research participants will receive EGFR-specific CAR T cells only. On Arm B of the study, research participants will receive CAR T cells directed at EGFR and CD19, a marker on the surface of B lymphocytes, following the hypothesis that CD19+ B cells serving in their normal role as antigen presenting cells to T cells will promote the expansion and persistence of the CAR T cells. The CD19 receptor harbors a different selection-suicide marker, HERtG. The primary objectives of the study will be to determine the feasibility of manufacturing the cell products, the safety of the T cell product infusion, to determine the maximum tolerated dose of the CAR T cells products, to describe the full toxicity profile of each product, and determine the persistence of the modified cell in the subject's body on each arm. Subjects will receive a single dose of T cells comprised of two different subtypes of T cells (CD4 and CD8 T cells) felt to benefit one another once administered to the research participants for improved potential therapeutic effect. The secondary objectives of this protocol are to study the number of modified cells in the patients and the duration they continue to be at detectable levels. The investigators will also quantitate anti-tumor efficacy on each arm. Subjects who experience significant and potentially life-threatening toxicities (other than clinically manageable toxicities related to T cells working, called cytokine release syndrome) will receive infusions of cetuximab (an antibody commercially available that targets EGFRt) or trastuzumab (an antibody commercially available that targets HER2tG) to assess the ability of the EGFRt on the T cells to be an effective suicide mechanism for the elimination of the transferred T cell products.
Children having selective ophthalmic artery chemotherapy for retinoblastoma under general anaesthesia may experience troubles during the procedure. The troubles are transient, may be severe and include hypoxemia, hypotension and bradycardia. All children having such trouble always fully recovered without any sequelae or prolonged length of stay. The investigators suspect that these phenomenons are caused by transient pulmonary hypertension.The objective is to see whether transient pulmonary hypertension and right-sided heart failure is present during theses phenomenon by trans-thoracic echocardiography.
The purpose of this study is to see if there is a difference between the development of the brain (neurodevelopment) in children who have been treated for retinoblastoma with multiple anesthetic exposures, compared with brain development in children who have never had anesthesia.
This protocol provides guidelines for the management of non-metastatic unilateral retinoblastoma and introduces an innovative adjuvant therapy for higher risk patients based upon the results of the Grupo de America Latina de Oncologia Pediatrica (GALOP) I study. Conservative therapy will be not protocolized.
A patient undergoing ophthalmic arterial chemosurgery may experience a sudden, profound decrease in lung compliance when the microcatheter is in the ICA or ophthalmic artery. However, underlying pathophysiology of the respiratory complication is unknown. In this study, the investigators are going to investigate the relation between underlying balance of parasympathetic and sympathetic tone and the respiratory complications by analyzing heart rate beat-to-beat variability.
