Retinoblastoma is the most common intraocular malignancy in infancy and childhood. The overall survival rate of retinoblastoma was reported to exceed 95% when children were early diagnosed with localized intraocular phase. The advanced retinoblastoma cases with central nervous system metastasis (CNS)is associated with exceedingly poor prognosis. CNS metastasis is the main cause of death in retinoblastoma. Meningeal involvement combined with spinal cord membrane involvement might be due to the meninges invasion and/or the spreading of CSF. As the most sensitive drug to retinoblastoma tumor cells in vitro, melphalan is the most important drug in the local treatment of retinoblastoma, and it is also an irreplaceable drug in the current eye preservation treatment, which greatly improves the success rate of eye preservation for advanced retinoblastoma. According to the research and the practice of vitreous injection (melphalan), the drug concentration in vitreous can effectively kill retinoblastoma tumor cells. It is reasonable to speculate that the tumor cells in CSF can be effectively killed by melphalan. Therefore, based on the above background, this study will explore the effectiveness and feasibility of intrathecal injection of melphalan in patients with CNS metastasis of retinoblastoma through a multicenter prospective study.

Study Type
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies. |

Trial ID:
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries. |
NCT04903678 |
Phase
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |
