Conditions: Retinoblastoma
Keywords: Retinoblastoma intra-arterial chemotherapy angiography
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 10
Healthy volunteers: no

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.

Arms:
arm 1: Single group assignment of patients with intraocular retinoblastoma, unilateral or bilateral.

Interventions: intervention 1: Melphalan hydrochloride
Intervention descriptions: intervention 1: 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.
