Objective:
To describe the efficacy of conservative management of retinoblastoma by an association of conservative ocular therapies and chemothermotherapy.
Design:
Phase II prospective nonrandomized trial.
Participants:
Eighty-three children were included (115 eyes).
Methods:
Conservative ocular therapies and chemothermotherapy (intravenous carboplatin followed by transpupillary thermotherapy to the tumor) after chemoreduction by 2 cycles of carboplatin and etoposide.
Main Outcome Measures:
Use of external beam therapy and ocular tumor control.
Results:
One hundred fifteen of the 147 affected eyes were eligible for conservative management. Nineteen children had unilateral lesions (22.8%), and 64 (77.1%) had bilateral lesions. Sixty-six children received neoadjuvant chemotherapy before ocular therapy, which consisted of one or a combination of several techniques: chemothermotherapy (65 children [86 eyes]) with a mean of 3 cycles per child, thermotherapy alone (22 children [24 eyes]), cryoapplication (49 children [58 eyes]), and iodine 125 brachytherapy (26 children [29 eyes]). Tumor control was achieved for 97 eyes (84%). At the end of the study, external beam radiotherapy (EBR) was necessary for a total of 9 children (11%) and 13 eyes (12%). Enucleation was necessary for a total of 23 eyes (20%), because of complications in 5 cases.
Conclusions:
Neoadjuvant chemotherapy with 2 cycles of carboplatin and etoposide followed by ocular therapy and chemothermotherapy achieves satisfactory tumor control and permits a low need for EBR.

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
