Promising new treatment for eye cancer in children

St. Jude Children's Research Hospital scientists have demonstrated a new locally applied treatment for the eye cancer retinoblastoma. The new treatment, tested on mice, reduced the size of the tumor and also did not cause the side effects common with chemotherapy.

This targeted therapy uses a customized drug to disable a specific molecule inside a growing cancer cell. It is delivered locally to the site of the disease, rather than using systematic treatment. Dr. Dyer, Ph. D., associate member of the St. Jude Department of Developmental Neurobiology said "The findings suggest that this treatment not only could offer children with retinoblastoma more effective and less toxic treatment, it could also increase the chance that their vision can be preserved by eliminating the tumor and preventing its spread from the eye to the rest of the body".

Retinoblastoma occurs in about 5,000 young children worldwide each year, arising from the immature retina, which is the part of the eye responsible for detecting light and color. A report on this work appears in the November 2nd issue of the journal Nature.
