This phase I trial studies the side effects and the best dose of a combination of chemotherapy and melphalan or melphalan alone in treating younger patients newly diagnosed with retinoblastoma within the eyeball (intra-ocular) that has spread to other places in the body and usually cannot be cured or controlled with treatment. Drugs used in chemotherapy, such as carboplatin, etoposide, vincristine sulfate, and melphalan, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. The treatment for intra-ocular retinoblastoma is either a standard combination of carboplatin, etoposide, and vincristine sulfate chemotherapy given into the vein (systemic) or melphalan chemotherapy given into the artery that feeds the eye (intra-arterial). However, either treatment alone may not be able to control advanced retinoblastoma. Giving a combination of standard chemotherapy and melphalan or melphalan alone in different interval schedules may be a better treatment for advanced intra-ocular retinoblastoma.

PRIMARY OBJECTIVES:
I. To determine the safety and tolerability of administration of selective intra-arterial (IA) melphalan in combination with systemic chemotherapy (carboplatin, etoposide, and vincristine; CEV) in a cohort of patients with newly diagnosed advanced intraocular retinoblastoma.
II. To determine the dose-limiting toxicity (DLT) and minimum tolerated dosing interval for combination IA melphalan therapy and CEV.
SECONDARY OBJECTIVES:
I. To describe response rates after IA melphalan combined with systemic chemotherapy in patients with newly diagnosed advanced intraocular retinoblastoma.
II. To describe ocular event-free survival with the use of combination IA therapy and systemic chemotherapy in this patient population.
III. To describe the salvage rate with triple IA therapy after failure of IA melphalan.
IV. To describe ocular event-free survival for unilateral retinoblastoma with only IA chemotherapy for Group C or Group A/B that have failed local therapy.
V. To describe visual outcomes using a standardized age-based assessment.
TERTIARY OBJECTIVES:
I. To describe melphalan pharmacokinetics after intra-arterial administration to the retina.
OUTLINE: Patients are assigned to 1 or 2 treatment cohorts.
COHORT I*: Patients receive carboplatin intravenously (IV) over 60 minutes on day 1, etoposide IV over 60 minutes on days 1-2, and vincristine sulfate IV over 1 minute on day 1 of weeks 1, 8, 15, and 22; OR weeks 1, 7, 13, and 19; OR 1, 6, 11, and 16: OR 1, 5, 9, and 13. Patients also receive melphalan intra arterially (IA)* over 15 minutes once in weeks 5, 12, 19, and 26; OR weeks 5, 11, 17, and 23: OR weeks 4, 10, 16, and 22; OR weeks 4, 9, 14, and 19.
COHORT II*: Patients receive melphalan IA over 15 minutes once in weeks 5, 12, 19, and 26; OR weeks 5, 11, 17, and 23; OR weeks 4, 10, 16, and 22; OR weeks 4, 9, 14, and 19.
NOTE*: Patients without improvement or progression after first course, which includes a course of systemic chemotherapy (CEA) and IA melphalan therapy, receive triple IA therapy comprising melphalan, topotecan hydrochloride, and carboplatin.
After completion of study treatment, patients are followed up monthly for 3 months, every 3 months for 1 year, and then every 6 months for 1 year.
