Intraocular Retinoblastoma

Retinoblastoma is one of highly curable diseases; today the total 5-year survival rate in patients with retinoblastoma exceeds 95%. The article summarizes the current world experience on treatment of patients with intraocular retinoblastoma. The treating skills of intraocular malignant tumor in children are a balance between the patient’s life and the preservation of an eye and its visual functions. The complex and challenging task is the treatment of common intraocular retinoblastoma groups «C», «D», «E» when the large size or localization of the tumor does not allow performing the local (focal) destruction of the tumor. As a rule, in such cases neoadjuvant chemotherapy (CT) is performed at the first stage in order to reduce the size of the tumor for further focal therapy. However, the analysed data on the effectiveness of neoadjuvant CT in combination with focal or radiotherapy demonstrated the limited possibilities of the proposed therapy. Local drug delivery in cancer therapy became a real breakthrough in the organ-preserving treatment of children with large intraocular retinoblastoma. The most widely used current methods of local drug delivery are intravitreal (IVitC) and selective intra-arterial chemotherapy (SIAC) as monotherapy or in combination with neoadjuvant CT and focal therapy which significantly increased the percentage of preserved eyes without radiotherapy administration or damage to the patient survival. The review discusses the different IVitC and SIAC techniques, chemotherapy schemes, dosages of chemotherapy, immediate and long-term complications of treatment.

Drug Delivery Devices

Background: Many drugs are delivered intranasally for local or systemic effect, typically in the form of droplets or aerosols. Because of the high cost of in vivo studies, drug developers and researchers often turn to in vitro or in silico testing when first evaluating the behavior and properties of intranasal drug delivery devices and formulations. Recent advances in manufacturing and computer technologies have allowed for increasingly realistic and sophisticated in vitro and in silico reconstructions of the human nasal airways. Objective: To perform a summary of advances in understanding of intranasal drug delivery based on recent in vitro and in silico studies. Conclusion: The turbinates are a common target for local drug delivery applications, and while nasal sprays are able to reach this region, there is currently no broad consensus across the in vitro and in silico literature concerning optimal parameters for device design, formulation properties and patient technique which would maximize turbinate deposition. Nebulizers are able to more easily target the turbinates, but come with the disadvantage of significant lung deposition. Targeting of the olfactory region of the nasal cavity has been explored for potential treatment of central nervous system conditions. Conventional intranasal devices, such as nasal sprays and nebulizers, deliver very little dose to the olfactory region. Recent progress in our understanding of intranasal delivery will be useful in the development of the next generation of intranasal drug delivery devices.
