HOW WE APPROACH CONSERVATIVE TREATMENT OF RETINOBLASTOMA IN SOUTH
AMERICA IN THE ERA OF LOCAL OCULAR TREATMENTS. A CONSENSUS OF THE GRUPO
AMERICA LATINA DE ONCOLOGIA PEDIATRICA (GALOP)
Abstract
Local therapies replaced systemic chemotherapy for ocular preservation
in retinoblastoma. In middle income countries, these techniques pose
specific challenges mostly related to more advanced disease at
diagnosis. The Grupo de America Latina de Oncologia Pediatrica (GALOP
developed a consensus document for the management of conservative
therapy for retinoblastoma. Intra-arterial chemotherapy (OAC) is the
preferred therapy, except those with less advanced disease or age
younger than 6 months. OAC allowed for the elimination of the use of
external beam radiotherapy in our setting. Intravitreal chemotherapy is
the preferred treatment for vitreous seeding. Enucleation is the
treatment of choice for advanced eyes.
