Retinoblastoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Treatment Option Overview
Treatment planning by a multidisciplinary team of cancer specialists, including a pediatric oncologist, ophthalmologist, and radiation oncologist, who have experience treating ocular tumors of childhood is required to optimize treatment planning.
Purpose of This Summary
This PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about cervical cancer prevention. It is intended as a resource to inform and assist clinicians who care for cancer patients. It does not provide formal guidelines or recommendations for making health care decisions.

Decrease risk of late sequelae from treatment, particularly subsequent neoplasms.
The type of treatment required depends on both the extent of the disease within the eye and whether the disease has spread beyond the eye, either to the brain or to the rest of the body. Eyes with glaucoma and those in which glaucoma resulted in buphthalmia are significantly associated with high-risk pathology risk factors and the occurrence of microscopically residual tumor. Enucleation is reserved for patients with advanced unilateral intraocular disease with no hope for useful vision in the affected eye. Subsequent risk of extraocular recurrence may be increased in the presence of high-risk histopathologic features such as massive choroid invasion, scleral invasion, and optic nerve invasion.[4,5]; [Level of evidence: 3iiDi] Clinical features predictive of these histological findings include eyes with glaucoma, especially those that have become buphthalmic. Routine bone marrow biopsy and lumbar puncture are not indicated, except when there is a high level of suspicion that the tumor has spread beyond the globe.[7,8] Examples include patients with an abnormal complete blood count or those whose tumors show massive choroidal involvement and which extend beyond the lamina cribrosa on pathologic examination of the enucleated specimen.
It is not uncommon for patients with retinoblastoma to have extensive disease within one eye at diagnosis, with either massive tumors involving more than one-half of the retina, multiple tumors diffusely involving the retina, or obvious seeding of the vitreous. For those with bilateral disease, systemic therapy may be used to treat the more severe eye.[9,10] There are data suggesting that the use of systemic chemotherapy may decrease the risk of development of trilateral retinoblastoma.
