  Purpose

The primary objective of this protocol is to evaluate the response rate of bilateral disease participants who have at least one eye with advanced intra-ocular retinoblastoma (stratum B) using upfront therapy with chemotherapy delivered directly to the eye. The main biology objective is to improve our understanding of the biology and tumorigenesis (how tumor develops) of retinoblastoma when biology specimens are available. As clinicians, the primary goal of the investigators for children with retinoblastoma is to provide optimal therapy using multiple treatment approaches [chemotherapy (into the vein and directly into membrane of eyeball), cryotherapy (freeze and destroy tumor), thermotherapy (laser or heat to destroy tumor), radiation therapy, and surgical removal of eye if needed) in an attempt to preserve the eye and vision whenever possible, while still curing the disease. Therefore, all children with non-metastatic retinoblastoma at St. Jude will be offered enrollment on this study.

PRIMARY OBJECTIVE:

  • To evaluate the response (complete + partial response) rate of bilateral disease participants who have at least one eye with advanced intraocular retinoblastoma (Stratum B) to two upfront courses of therapy consisting of subconjunctival carboplatin and systemic topotecan.

SECONDARY OBJECTIVES:

  • To evaluate the ocular survival of eyes and event-free survival of participants by strata.
  • To prospectively analyze intraocular disease tissue for participants with at least one eye undergoing enucleation in order to identify the mechanism of RB1 bi-allelic inactivation. Participants may undergo upfront enucleation (due to advanced disease at diagnosis) or may receive enucleation due to progressive disease during protocol therapy.

Primary Outcome Measures:
  • Response rate (complete or partial response) [ Time Frame: After two upfront courses of chemotherapy (approximately two months after patient enrollment) ] [ Designated as safety issue: No ]
    Stratum B patients, those Stratum B patients who had no significant subretinal seeding and received vincristine and topotecan are not evaluable for this primary objective.


Secondary Outcome Measures:
  • ocular survival [ Time Frame: at end of study (approximately three years after the last patient enrollment) ] [ Designated as safety issue: Yes ]
    Ocular survival per eye will be defined as the time interval from study enrollment to date of enucleation or to date of last contact for eyes that have not been enucleated.

  • Event-free survival [ Time Frame: at end of study (approximately three years after the last patient enrollment) ] [ Designated as safety issue: No ]
    Event-free survival per eye will be defined as the time interval from date on study to date of first event (where an event includes external beam radiation or enucleation) or to the date of last contact for eyes without events.

  • The mechanism (or frequencies) for each RB1 biallelic inactivation [ Time Frame: At end of study (approximately one year after the last patient is enrolled on study) ] [ Designated as safety issue: No ]
    The tumor tissue samples will be obtained from participant who has at least one eye undergoing enucleation.

Arms Assigned Interventions
Experimental: Stratum A

Participants with early bilateral or unilateral (unifocal or multifocal) retinoblastoma (R-E I-III, IC A-B; R-E IV with IC A or B; or IC C with limited sub-retinal seeding), and participants with bilateral disease in whom the advanced eye has been enucleated upfront (without any high risk histopathology) and the remaining eye has early stage disease (as defined above).

Interventions (see detailed description): vincristine, carboplatin, topotecan, filgrastim or PEG-filgrastim, and focal therapy including cryotherapy, laser photocoagulation, thermo-therapy, plaque radiotherapy.

Drug: topotecan
Given IV over 30 minutes.
Other Names:
  • TOPO
  • Hycamtin(R)
Drug: filgrastim
Given subcutaneously 24-36 hours after chemotherapy for 7-10 days, until absolute neutrophil count (ANC) is >2,000/µL on one occasion after the expected nadir.
Other Names:
  • G-CSF
  • Neupogen(R)
Drug: PEG-filgrastim
Given subcutaneously 24-36 hours after chemotherapy for 7-10 days, until ANC is >2,000/µL on one occasion after the expected nadir.

Focal treatments will be administered any time after the second course of chemotherapy. In select cases of very early stage retinoblastoma, participants may receive focal therapies only and chemotherapy will be held at the discretion of the treating team. If there is any evidence of progression or unsatisfactory results, the participant will begin chemotherapy as per Stratum A. For selected participants an effort will be made to perform sequential chemo-thermotherapy. In these cases, carboplatin will be administered one or two hours prior to thermotherapy. In some participants, additional doses of carboplatin may be required after the completion of the 8 scheduled courses in order to achieve tumor control through thermotherapy.
Other Names:

  • plaque radiotherapy
  • thermo-chemotherapy
  • episcleral plaque brachytherapy
Experimental: Stratum B

Participants considered candidates for conservative management including those:

  1. Participants with bilateral retinoblastoma who have R-E IV-V and IC D in one eye
  2. Participants with advanced unilateral (unifocal or multifocal) retinoblastoma (R-E IV-V and IC D-E) who demonstrate foveal sparing by the tumor during EUA. Due to foveal sparing, these patients have potential for vision preservation.

EBRT will be administered to any eye in which the disease is considered to be not controllable with focal treatments alone, and in participants with enucleated eyes in which high risk of orbital and/or central nervous system disease is documented histologically (high-risk group with disease extension beyond the sclera or cornea, or beyond the cut end of the optic nerve). EBRT will be administered using standard techniques practices with the objective of limiting dose to normal tissues including the hypothalamic-pituitary unit, supratentorial brain, orbit, cochleae and contralateral eye when indicated. Participants will be evaluated on an individual basis to determine whether they might benefit from referral for proton therapy.
