Filter by:Retinoblastoma (RB) is the most common intraocular malignancy in children and accounts for 11% of all cancers in children under the age of 1 year. Although the incidence of RB is low, approximately 1/15,000 ~ 1/20,000, it tends to metastasize to the intracranial area through the optic nerve pathway leading to poor prognosis for patients with RB. Currently, with the emergence of new administration routes, such as intravitreal and intrarterial chemotherapy, the rate of eye preservation has been effectively improved. However, the use of high doses of chemotherapeutic agents may lead to visual impairments due to long-term retinal toxicity and some tumors recur or become resistant to chemotherapeutic agents after treatment. In such cases, ocular resection is the only option to prevent extraocular metastasis and death. Therefore, studies on retinoblastoma are currently focused on finding new targeted therapies to increase anti-tumor activity and reduce side effects. In this study, a novel targeting NUDT21 siRNA drug will be used to treat patients with refractory retinoblastoma. This drug promotes tumor apoptosis by regulating the 3'UTR plus tail of SMC1A, which makes the proliferative activity of tumor cells weaken and achieves tumor control. At the same time, since the targeted drug only focuses on tumor cells, it has reduced side effects compared with existing local chemotherapy regimens. Based on the above background, this study will explore the feasibility and effectiveness of intravitreal injection of NUDT21 siRNA in patients with refractory retinoblastoma through a two-center prospective study.
Rationale: Currently baseline brain MRI (magnetic resonance imaging) with extended follow-up of pineal cysts is systematically performed in all new retinoblastoma (Rb) patients, because children with hereditary retinoblastoma have an increased risk of primitive neuroectodermal tumors (PNET) that are histopathologically identical to the retinal tumors (1). The prevalence of developing a PNET in combination with unilateral or bilateral hereditary Rb is 5-15% (2). Treatment is difficult and the prognosis is poor as only few survivors are reported. Only patients with small asymptomatic PNETs (<15 mm) are potentially curable. Objective: The main objective of this prospective multicenter study is to evaluate the current strategy of baseline MRI screening of the brain in newly diagnosed retinoblastoma patients, with extended follow-up of selected patients with simple and complicated pineal cysts. Study design: The investigators propose a prospective cohort study (part of a larger multicenter study) to investigate the diagnostic accuracy and survival of baseline MRI screening of the pineal gland in new patients with retinoblastoma, with extended follow-up of selected patients with pineal cysts for early detection of pineoblastoma. Study population: Within the European Retinoblastoma Imaging Collaboration (ERIC) about 150 new retinoblastoma patients are diagnosed every year. About 10 percent of all new retinoblastoma patients will be diagnosed at the VUmc. According to our sample size calculations the investigators will need 334 Rb patients. Main study parameters/endpoints: The primary endpoint of the study is pineoblastoma or supra- / parasellar PNET on MRI (index test). Because a gold standard will not be available, tumor cells in cerebrospinal fluid, histopathological confirmation, clinical disease progression during follow-up, and/or follow-up MRI diagnostics will be used as a composite reference standard in case of a positive index test and clinical diagnosis of pineoblastoma or supra- / parasellar PNET within one year of the last MRI will be used as a composite reference standard in case of a negative index test.
Patients with heritable retinoblastoma are at risk to develop an intracranial brain tumor, which is often fatal. The investigators intend to look at the incidence and survival of trilateral retinoblastoma (which is a brain tumor that can either be located in the pineal gland or elsewhere in the brain) in retinoblastoma patients globally. All retinoblastoma patients from participating centers will be included. The investigators hypothesize that the apparent incidence of trilateral retinoblastoma (especially the usually later diagnosed pineal trilateral retinoblastoma) in low-income countries will be lower because of low chances of surviving the ocular tumors at about 50% and also because of possible under-diagnosis. Therefore, as retinoblastoma care improves in low-income countries the incidence of (pineal) trilateral retinoblastoma might go up. Knowledge about incidence and survival can help improve health practices in parts of the world where this might be needed. Therefore this global study firstly aims 1) to evaluate survival after trilateral retinoblastoma and factors influencing survival and 2) to evaluate incidence of trilateral retinoblastoma by country income level. The study will run from 2024 through 2027.
A retrospective crosssectional observational study of the effects of oncological treatment and frequent general anesthesia on neuropsychological development, psychosocial functioning (in terms of anxiety, depression, peer relations, perceived cognitive functioning and potential trauma) and health related quality of life in children and young adults who were treated or screened for retinoblastoma.
Newborn screening (NBS) is a global initiative of systematic testing at birth to identify babies with pre-defined severe but treatable conditions. With a simple blood test, rare genetic conditions can be easily detected, and the early start of transformative treatment will help avoid severe disabilities and increase the quality of life. Baby Detect Project is an innovative NBS program using a panel of target sequencing that aims to identify 126 treatable severe early onset genetic diseases at birth caused by 361 genes. The list of diseases has been established in close collaboration with the Paediatricians of the University Hospital in Liege. The investigators use dedicated dried blood spots collected between the first day and 28 days of life of babies, after a consent sign by parents.
The purpose of this study is to evaluate the safety and efficacy of TAS-116 with palbociclib in two groups of patients: - Patients with advanced breast cancer that has become worse after taking palbociclib alone - Patients with cancers that have an abnormality in a gene called the "retinoblastoma gene".
This phase II trial tests the safety and side effects of adding melphalan (by injecting it into the eye) to standard chemotherapy in early treatment of patients with retinoblastoma (RB). RB is a type of cancer that forms in the tissues of the retina (the light-sensitive layers of nerve tissue at the back of the eye). It may be hereditary or nonhereditary (sporadic). RB is considered harder to treat (higher risk) when there are vitreous seeds present. Vitreous seeds are RB tumors in the jelly-like fluid of the eye (called the vitreous humor). The term, risk, refers to the chance of the cancer not responding to treatment or coming back after treatment. Melphalan is in a class of medications called alkylating agents. It may kill cancer cells by damaging their deoxyribonucleic acid (DNA) and stopping them from dividing. Other chemotherapy drugs given during this trial include carboplatin, vincristine, and etoposide. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Vincristine is in a class of medications called vinca alkaloids. It works by stopping cancer cells from growing and dividing and may kill them. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill cancer cells. Adding melphalan to standard chemotherapy early in treatment may improve the ability to treat vitreous seeds and may be better than standard chemotherapy alone in treating retinoblastoma.
Retinoblastoma is the most common eye cancer of childhood. Eye-preserving therapies require routine monitoring of retinoblastoma regression and recurrence to guide corresponding treatment. In the current study, we develop a deep learning algorism that can simultaneously identify retinoblastoma tumours on Retcam images and distinguish between active and inactive retinoblastoma tumours. This algorism will be validated through a prospectively collected dataset.
The purpose of this study is to determine the effect of 3 cycles of chemotherapy(CEV) in the treatment of Stage I enucleated retinoblastoma.
