Inclusion Criteria

Inclusion Criteria:<br><br> - Patient must be < 18 years of age at enrollment<br><br> - Patient must have newly diagnosed intraocular (localized) retinoblastoma and meet<br> one of the following criteria:<br><br> - Unilateral Group D retinoblastoma with vitreous seeding; OR<br><br> - Bilateral retinoblastoma with worst eye Group D, with vitreous seeding present<br> and the contralateral eye is Group A-C; OR<br><br> - Bilateral Group D retinoblastoma with at least one eye with vitreous seeding;<br> OR<br><br> - Bilateral retinoblastoma with one Group D eye with vitreous seeding and one<br> Group E eye where the Group E eye has been enucleated prior to any therapy.<br> Note exclusion for high-risk features<br><br> - Bilateral retinoblastoma with one Group D eye with vitreous seeding and one<br> Group E eye where the Group E eye has not been enucleated prior to any therapy<br> at the discretion of the treating physician. Note exclusion for patients with<br> evidence of metastatic or extra orbital spread<br><br> - Patients must have a performance status corresponding to Eastern Cooperative<br> Oncology Group (ECOG) scores of 0, 1 or 2. Use Karnofsky for patients > 16 years of<br> age and Lansky for patients =<16 years of age<br><br> - Peripheral absolute neutrophil count (ANC) >= 750/uL (must be performed within 7<br> days prior to enrollment unless otherwise indicated)<br><br> - Platelet count >= 75,000/uL (transfusion independent) (must be performed within 7<br> days prior to enrollment)<br><br> - A serum creatinine based on age/gender as follows (must be performed within 7 days<br> prior to enrollment; must be repeated prior to the start of protocol therapy if > 7<br> days have elapsed from their most recent prior assessment):<br><br> - 1 month to < 6 months = 0.4 (male and female)<br><br> - 6 months to < 1 year = 0.5 (male and female)<br><br> - 1 to < 2 years = 0.6 (male and female)<br><br> - 2 to < 6 years = 0.8 (male and female)<br><br> - 6 to < 10 years = 1.0 (male and female)<br><br> - 10 to < 13 years = 1.2 (male and female)<br><br> - 13 to < 16 years = 1.5 (male) and 1.4 (female)<br><br> - >= 16 years = 1.7 (male) and 1.4 (female) OR - a 24-hour urine Creatinine<br> clearance >= 70 mL/min/1.73 m^2 OR - a glomerular filtration rate (GFR) >= 70<br> mL/min/1.73 m^2. GFR must be performed using direct measurement with a nuclear<br> blood sampling method OR direct small molecule clearance method (iothalamate or<br> other molecule per institutional standard)<br><br> - Note: Estimated GFR (eGFR) from serum creatinine, cystatin C or other estimates<br> are not acceptable for determining eligibility<br><br> - For patients < 1 month of age, serum creatinine levels must be < 1.5 x the<br> treating institution's creatinine upper limit of normal (ULN) for patients<br> < 1 month of age or the creatinine clearance or radioisotope GFR must be<br> >= 70 mL/min/1.73 m^2<br><br> - Total bilirubin =< 1.5 x upper limit of normal (ULN) for age (must be performed<br> within 7 days prior to enrollment; must be repeated prior to the start of protocol<br> therapy if > 7 days have elapsed from their most recent prior assessment)<br><br> - Serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) =< 135<br> U/L (must be performed within 7 days prior to enrollment; must be repeated prior to<br> the start of protocol therapy if > 7 days have elapsed from their most recent prior<br> assessment)<br><br> - Note: For the purpose of this study, the ULN for SGPT (ALT) has been set to the<br> value of 45 U/L<br><br>Exclusion Criteria:<br><br> - Patients with evidence of metastatic or extra-orbital spread<br><br> - Patients must not have an invasive infection at time of protocol entry<br><br> - Patients must not have had any prior anti-cancer therapy other than cryotherapy<br> and/or laser therapy (green or infrared) to the study eye(s) and non-study eye,<br> including systemic chemotherapy, intra-arterial chemotherapy, radioactive plaque,<br> brachytherapy, or radiation therapy.<br><br> - Note: A study eye is defined as being Group D with vitreous seeding. Patients<br> may have had enucleation of one eye as long as the remaining eye is Group D<br> with vitreous seeds<br><br> - Patients with bilateral disease who undergo enucleation of a Group E eye prior to<br> initiation of therapy and show evidence of high-risk histopathology features in the<br> enucleated eye. High-risk histopathology includes choroid involvement >= 3 mm, post<br> lamina optic nerve involvement, full thickness scleral invasion or optic nerve<br> invasion to the cut end<br><br> - Female patients who are pregnant since fetal toxicities and teratogenic effects have<br> been noted for several of the study drugs. A pregnancy test is required for female<br> patients of childbearing potential<br><br> - Lactating females who plan to breastfeed their infants<br><br> - Sexually active patients of reproductive potential who have not agreed to use an<br> effective contraceptive method for the duration of their study participation<br><br> - All patients and/or their parents or legal guardians must sign a written informed<br> consent<br><br> - All institutional, Food and Drug Administration (FDA), and National Cancer Institute<br> (NCI) requirements for human studies must be met
