Diagnosis: Patients with untreated Group C/D/E unilateral Retinoblastoma at presentation without an indication for immediate enucleation (neovascular glaucoma or orbital pain) (Stratum A), or patients with a history of bilateral retinoblastoma and recurrent and/or refractory intraocular retinoblastoma where chemotherapy, external beam radiation and/or enucleation remain the only known option for disease control (Stratum B).
Therapeutic Options: Chemotherapy, External Beam Radiation therapy and/or Enucleation
Lansky 50 for patients ≤ 10 years of age; Karnofsky ≥ 50 for patients > 10 years of age. Patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.
Prior Therapy: Stratum A: No prior therapy is allowed. Stratum B: Patients must have local relapsed/refractory disease after receiving standard upfront therapy involving at least one chemotherapeutic regimen. There is no limit to prior chemotherapeutic regimens permitted. Prior radiation therapy is permitted.
Patients must have recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study, as described below:
- Myelosuppressive chemotherapy: patients must not have received myelosuppressive chemotherapy within 3 weeks of study enrollment.
- Biologic therapies: Patients must not have received biologic anti-cancer agents within one week of study enrollment.
- Radiation therapy: Four weeks must have elapsed since external beam radiation therapy, if given.
Adequate Bone Marrow Function Defined as:
- Peripheral absolute neutrophil count (ANC) greater than or equal to 750/uL
- Platelet count greater than or equal to 75,000/uL (transfusion independent, defined as not receiving platelet transfusions within a 7-day period prior to enrollment)
- Hemoglobin greater than or equal to 8.0 gm/dL (may receive RBC transfusions)
Adequate Renal Function Defined as:
-Maximum serum creatinine based on age as follows: 1 to < 2 years-08 mg/dL; 6 to < 10 years-1 mg/dL; 10 to < 13 years-1.2 mg/dL; 13 to 15 years-1.5 mg/dL for boys and 1.4 mg/dL for girls.
OR

Adequate Liver Function Defined As:
- Bilirubin (sum of conjugated + unconjugated) less than or equal to 1.5 x upper limit of normal (ULN) for age
- SGPT (ALT) less than or equal to 5 x upper limit of normal (ULN) for age
- Serum albumin greater than or equal to 2 g/dL
Informed Consent: All patients and/or their parents or legal guardians must sign a written informed consent. Assent, when appropriate, will be obtained according to institutional guidelines.
