Brief summary
The purpose of this study is to show that chemotherapy delivered directly through the artery supplying the eye (ophthalmic artery) to patients with retinoblastoma is a safe and effective treatment alternative to conventional systemic chemotherapy, external beam radiation, and surgical removal of the eye.
Detailed description
Delivering the chemotherapeutic agent in the arterial system through the ophthalmic artery transforms the treatment of retinoblastoma from systemic chemotherapy to local chemotherapy. Administration of the drug directly to the targeted site thus avoids the complications and adverse events associated with toxicity from systemic, rather than local, chemotherapy.
Interventions
Drug administered intra-arterially (injection in the artery). Standard dose: 2.5mg (3-6 month old) 3.0 mg (6-12 month old) 4.0 mg (1-3 year old) 5.0 mg (\>3 years old) Dose modification: decrease standard dose by 25% if there are signs of toxicity. Increase the dose by 25% if there is inadequate tumor response. Frequency: 2 treatment cycles at 3-4 week intervals, with a third treatment cycle administered if the tumor requires it. Dose not to exceed 0.5mg/kg, per treatment cycle.

Eligibility
Inclusion criteria
* Patients newborn to 18 years old. * Patients with intraocular retinoblastoma, unilateral or bilateral, who would be treated either by systemic chemotherapy, EBR, or enucleation would be considered for this study.
Exclusion criteria
* Patients over the age of 18. * Patients with small, localized intraocular Rb amenable to focal therapy (laser or cryotherapy). * Patients with extraocular disease evident on MRI (extension into the optic nerve), massive choroidal/uveal invasion (grade IIC or IID per ARET0332) or disease outside the globe evident on MRI or physical examination. * Documented hypercoagulable disorders or vasculopathies. * Laboratory

| Intra-arterial Chemotherapy IAC is offered to all patients with intraocular Rb who are deemed eligible after evaluation under anesthesia (EUA),with the exception of those few patients for whom focal modalities (i.e., laser or cryotherapy) would be effective.In cases of bilateral disease, both eyes would be treated sequentially during the same procedure utilizing the same femoral access site.
Two cycles of IAC will be performed at 3 to 4 week intervals. Melphalan dosing: 3-6 mth-old, 2.5mg; 3-12 mth-old, 3mg; 1-3 yr-old, 4mg; \>3 yr-old, 5mg. For those tumors that have shown appropriate response and are amenable to local therapies, then no additional IAC will be performed. If the tumors do not regress after 2 cycles, then a third cycle of IAC will be offered. Local therapies (laser, cryotherapy) will not be given during the EUAs conducted prior to each treatment session, but will be allowed after toxicity and response has been assessed 3-4 weeks after the final cycle of intra-arterial therapy. | 10 |
