The main research interest of Dr. Chévez-Barrios and her laboratory is the study of retinoblastoma, including cancer stem cells, suicide gene therapy for retinoblastoma, the study of metastatic properties of retinoblastoma and preclinical models of the tumor. Other topics of interest are ocular gene therapy, cataractogenesis, vascular proliferation in hypoxic ocular diseases and corneal diseases. Dr. Chévez-Barrios’ laboratory is currently participating in a project on gene therapy for retinoblastomas in collaboration with the Texas Children’s Cancer Center, the Center for Gene Therapy of Texas Children's Hospital and Baylor College of Medicine. Pre-clinical studies and a phase 1 clinical trial of vitreous seed of retinoblastoma have been completed. The phase II clinical trial is in preparation.

Dr. Chévez-Barrios is a committee member responsible for evaluating all enucleated eyes from the prospective multicenter study of the ARET0332 Children’s Oncology Group protocol on “A Study of Unilateral Retinoblastoma With and Without Histopathologic High-Risk Features and the Role of Adjuvant Chemotherapy.” She is is also interested in the biological differences between retinoblastoma cell lines that have the capability of producing metastasis, and those that behave less aggressively and remain as intraocular tumors.
