Children’s Hospital Los Angeles Identifies Molecular Markers to Increase Precision in Treatment of Retinoblastoma
Retinoblastoma is a cancer of the eye that occurs in infants and toddlers and can lead to loss of vision, loss of one or both eyes, and even death. Unlike most tumors, these cannot be biopsied because of the risk of spreading cancer to the rest of the body. In 2017, Jesse Berry, MD, surgeon and ocular oncologist at Children’s Hospital Los Angeles, discovered that fluid removed from the eye during treatment of retinoblastoma contained tumor DNA and functioned as a liquid biopsy—providing information about the tumor and opening the door to earlier diagnosis and treatment.
