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.
This study compares the effects of balloon technology and microcatheter technology on the eye protection rate of neuroblastoma
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.
Retinoblastoma is the most common intraocular tumor in children..IAC--Targeted Treatment for Intraocular Retinoblastoma,Is minimally invasive procedure that infuse chemotherapy select into the ophthalmic artery, its can increasing the drug concentration reaching the tumor and reducing systemic toxicity compared with traditional intravenous treatment.: one is Ballon technique , another is selective ophthalmic artery infusion.This study evaluates the difference of Ballon technique and selective ophthalmic artery infusion effect in the treatment of retinoblastoma. Half of participants will receive, Ballon technique while the other half will receive selective ophthalmic artery infusion
