Retinoblastoma: animal models.

Employment of animal models in basic research has significantly advanced the understanding of fundamental processes underlying tumorigenesis in retinoblastoma, including elucidating the complex role of pRb and other related protein products in cell cycle regulation, apoptosis, DNA damage responses, and terminal differentiation. The evolution of therapy for retinoblastoma has also been facilitated through translational research using in vivo models, including xenograft and genetically engineered systems. In retinoblastoma, these models provide a valuable preclinical context for testing the efficacy and safety of conventional chemotherapy, radiotherapy, or novel agents on tumor growth, tissue invasion, and metastasis.

Posterior pole tumor update.

This chapter focuses on the diagnosis and management of choroidal melanoma in light of recent findings from the COMS. Retinoblastoma is emphasized to describe recent trends in primary treatment away from EBRT and toward chemoreduction with local therapy. In addition, vascular and glial tumors of the retina and tumors of the retinal pigment epithelium are described because of the association between these lesions and systemic disease. Recent advances in treatment and genetic testing for these diseases are discussed. Finally, ocular metastasis, intraocular lymphoid tumors, and intraocular leukemia are included because of their importance in determining systemic treatment and prognosis. The chapter gives an overview of important posterior pole tumors and highlights recent developments in the management of each intraocular disease process.
