About

Conservative treatments of retinoblastoma (RETINO 2011) 1. -Multicentric non randomised, phase II study for the patients treated by chemoreduction (VP16, carboplatin) followed by chemothermotherapy without laser treatment at day 8 2. -Multicentric non randomised, phase II study for the patients with bilateral very asymmetric dis-ease (Group D eye on one of the eye) or unilateral presentation groups B/C/D according to the age and vitreous seeding 3. - Multicentric non randomised, phase II study for the patients treated by 6 cycles of three drugs regimen and local treatments for bilateral group D eyes or on the only eye.

Inclusion criteria

Study 1 inclusion criteria: * Patients affected by unilateral retinoblastoma groups A, B (according to the age), group C (according to the age and vitreous seeding),or bilateral retinoblastoma groups A, B, C (excluding the eyes with macular threat and bilateral group D eyes or on the only remaining eye) amenable to a conservative treatment (at least on one eye in bilateral disease) but needing initial chemotherapy because of the location, the size of the lesion (more than 4 mm of diameter), a vision threat or risks of intravitreal relapse making those patients not amenable to chemothermotherapy first line. * Patients less than six months of age with unilateral retinoblastoma groups B, C, D, or bilateral very asymmetric with one eye group D and the other amenable to local treatments without chemotherapy. * Children from 0 to 6 years old. Study 2 inclusion criteria: * Patients affected by unilateral or bilateral retinoblastoma group B (according to the age), group C (according to the age and vitreous seeding), or group D. * Patients affected by bilateral retinoblastoma very asymmetric with a group D eye that can be treated by intraarterial chemotherapy by Melphalan and the other amenable to local treatments without chemotherapy. * Children from 6 months to 6 years old. Study 3 inclusion criteria: * Children affected of bilateral group D retinoblastoma or on the only eye amenable to conservative treatment. * Children from 0 to 6 years old. Common inclusion criteria: * Patients not previously treated by chemotherapy or radiotherapy for this tumour or another cancer. * No contra-indications to the study treatments * Possible long term follow-up. * Written informed consent of the parents or the legal representative. * Patients having social security cover.

Exclusion criteria

Study 1 exclusion criteria: * Patients for whom a local treatment is possible without initial chemotherapy (tumour smaller than 4 mm and located far from optic nerve head or macula). * Patients with an unilateral group D with massive tumour or group E eyes needing enucleation first line or after initial chemotherapy (in case of buphthalmia or suspected optic nerve invasion or extrascleral extension). * Patients affected by bilateral retinoblastoma very asymmetric with a group D eye that can be treated by intraarterial chemotherapy by Melphalan and the other amenable to local treatments without chemotherapy. * Patients with bilateral retinoblastoma and bilateral group D eyes or on the only remaining eye or presenting a bilateral macular threat requiring conservative treatment by a 6 cycles, three drugs regimen. Study 2 exclusion criteria: * Patients with a unilateral group D (extensive) or B or C but covering the optic nerve head or group E eyes for which enucleation is warranted first line or after chemotherapy (in case of buphthalmia or suspected optic nerve invasion or extrascleral extension). * Patients with unilateral group D eye with tumour volume of more than 50% of eye volume, for whom a massive choroidal invasion could be associated (on clinical or imaging criteria) and for which enucleation is warranted. Study 3 exclusion criteria: * Patients for whom a local treatment is possible without chemoreduction (tumour smaller than 4 mm, distant from macula and from optic nerve head). * Patients affected by bilateral retinoblastoma very asymmetric with a group D eye that can be treated by intraarterial chemotherapy by Melphalan and the other amenable to local treatments without chemotherapy. * Patients with bilateral retinoblastoma without macular threat or groups A, B, C than can be treated with chemoreduction by VP16 and Carboplatin then chemothermotherapy without laser at day 8. Common exclusion criteria: * Patients older than 6 years old. * Patients with extraocular retinoblastoma. * Patients with a disease being a contra-indication to chemotherapy. * Patients anteriorly treated by chemotherapy. * Patients anteriorly treated by external beam irradiation. * Patients anteriorly treated for another cancer. * Follow-up not possible due to geographic distance from the center or for social or psychological reasons. * Parents not having accepted the therapeutic strategy after explanations by the investigator. * Contra-indication to the use of one of the drugs used in the study.

Drug: VP16, carboplatin
(IA) Intraarterial Melphalan
Other group
Description:
