Methods. Six cycles of carboplatin 560 mg/m2 on day 1, etoposide<br />
150 mg/m2 on days 1 and 2, and vincristine 1.5 mg/m2 on day 1 were<br />
prescribed. Patients less than 36 months of age were dosed on a per<br />
kilogram basis (conversion: 30 kg = 1 m2). Toxicity was graded according<br />
to the National Cancer Institute Common Toxicity and Adverse Event<br />
Criteria, Version 3.0.<br />
Results. Five hundred and twenty-one cycles were administered to 93<br />
patients. The median age was 28 months (range, 2-77). Three patients<br />
were under 6 months of age at initiation of chemotherapy. Grade 3-4<br />
myelosuppression (anemia or thrombocytopenia or neutropenia)<br />
was noted in 3% of cycles. Fever and neutropenia occurred in 2 % of<br />
cycles. All other Grade 3 and higher toxicities were seen in less than 1%<br />
of cycles administered. No patient had documented hearing loss and<br />
no patient developed a second malignancy. There were no treatment<br />
related deaths.<br />
Conclusions. Standard dose CEV is associated with a very low rate of<br />
toxicity. Pediatric ophthalmologists and oncologists should not hesitate<br />
to recommend this life preserving treatment.<br />

Purpose. Intraocular retinoblastoma treatments often associate chemotherapy<br />
and focal treatments. The protocols vary and may combine two or three drugs,<br />
and different number of cycles associated to the local adjuvant treatments. A<br />
first prospective protocol of conservative treatments in our institution showed<br />
the efficacy of the use of two courses of chemoreduction with etoposide and<br />
carboplatin, followed by chemothermotherapy using carboplatin as a single<br />
agent. In order to decrease the possible long term toxicity of chemotherapy<br />
due to etoposide a prospective randomized chemoreduction protocol was<br />
conducted using vincristine and carboplatin vs. etoposide carboplatin<br />
Methods. The study was proposed when intial tumor characteristics<br />
did not allow front-line local treatments. The phase II randomized study<br />
of reduction chemotherapy used treatments vincristin carboplatin<br />
or etoposide carboplatin, and followed by local treatment including<br />
chemothermotherapy with carboplatin only. Primary endpoint was the<br />
need for secondary enucleation or EBRT not exceeding 40% at two years.<br />
Results. 55 children, 65 eyes were included in the study (May 2004- August 2009).<br />
32 eyes (27 children) were treated conservatively in the arm etoposidecarboplatin<br />
and 33 (28 children) eyes in the arm vincristin carboplatin.<br />
At two years after treatment 23/33 (69.7%) eyes were treated and salvaged<br />
without EBRT or enucleation in the arm vincristin-carboplatin and 26/32<br />
(81.2%) in the arm etoposide and carboplatin.<br />
Conclusions. Neoadjuvant chemotherapy by two cycles of vincristine and<br />
carboplatin followed by chemothermotherapy (laser diode hyperthermia<br />
combined to carboplatine as single drug) does not seem to offer an optimal<br />
local control.<br />

Purpose. To evaluate the outcome of 105 eyes with intraocular<br />
retinoblastoma treated with conservative treatment.<br />
Methods. Retrospective review of 85 consecutive patients with<br />
intraocular retinoblastoma (34 unilateral cases and 51 bilateral cases).<br />
Results. A total of 105 eyes, 9 group A eyes (9%), 22 group B eyes (21%),<br />
17 group C eyes (16%), 43 group D eyes (41%) and 14 group E eyes (13%)<br />
were treated.<br />
Systemic chemotherapy associated with local therapy was performed<br />
as first treatment in 97 eyes (92%). Periocular carboplatin injection<br />
(20mg/2ml) was used in 13 group D eyes (30%) and in 7 group E eyes<br />
(50%) associated with systemic chemotherapy.<br />
Disease progression was observed in 57% (n=60 eyes) during the first<br />
treatment period (B-32%, C-35%, D-86% and E-86%). Enucleation was<br />
performed in 28 eyes (27%).<br />
Recurrence appeared in 18 eyes from 77 eyes initially saved, after<br />
a mean follow up of 7 months (range 4-12 months). Seven eyes were<br />
enucleated.<br />
Considering all forms of conservative treatments and excluding EBRT,<br />
the final eye salvage rate was respectively: 100%/100% for group A,<br />
95%/95% for group B, 88%/82% for group C, 49%/40% for group D,<br />
54%/54% for group D with periocular carboplatin and 28%/14% for<br />
group E.<br />
A total of 70 eyes (67%) were saved.<br />
Conclusions. Conservative treatment for intraocular retinoblastoma<br />
using systemic chemotherapy associated with local therapy is very<br />
efficient for initial disease. Most of the enucleations (80%) were<br />
indicated during the first treatment period. Recurrence appear most in<br />
the first year of follow up.<br />
