Abstract
Of the different modalities used to treat retinoblastoma, a chemothermotherapeutic regimen combining carboplatin and thermotherapy (also termed focal therapy), and the application of melphalan as a monotherapy, are particularly successful. Some studies indicate that melphalan shows potential when applied in combination with focal therapy, and yet is not applied in this combination. Here we describe a series of synthetically modified melphalan derivatives that display enhanced cytotoxicity relative to melphalan itself, with some displaying further enhancements in cytotoxicity when applied in combination with heat (used as a model for thermotherapy). The synthetic approach, which involves modifying melphalan with perfluorous chains of varying lengths via an ester linker, could lead to a more effective treatment option for retinoblastoma with reduced side-effects, which is a key limitation of melphalan.

Comparing efficacy and side effects of two systemic chemotherapy regimens for eye-preserving therapy in children with retinoblastoma. Pediatr Blood Cancer 2022; 69:e29362.

Abstract
BACKGROUND Eye-preserving therapy in retinoblastoma comprises systemic chemotherapy, but studies analyzing the efficacy of different chemotherapy regimens are scarce. METHODS The efficacy and side effects of two different eye-preserving chemotherapy regimens containing either vincristine, etoposide, and carboplatin (VEC) or cyclophosphamide, vincristine, etoposide, and carboplatin (CyVEC) were compared in a prospective non-interventional observational study including children diagnosed with retinoblastoma between 2013 and 2019 in Germany and Austria. Event-free eye survival (EFES) and overall eye survival (OES) of all 164 eyes treated with both regimens and risk factors were investigated. RESULTS The EFES after VEC (2-year EFES 72.3%) was higher than after CyVEC (2-year EFES 50.4%) (plogrank < .001). The OES did not differ significantly between the two treatment groups (plogrank = .77; 2-year OES VEC: 82.1% vs. CyVEC: 84.8%). Advanced International Classification of Retinoblastoma (ICRB) group was prognostic for a lower EFES (plogrank < .0001; 2-year EFES ICRB A/B/C 71.3% vs. ICRB D/E 43.0%) and OES (plogrank < .0001; 2-year OES ICRB A/B/C 93.1% vs. ICRB D/E 61.5%). The multivariate analysis showed that age at diagnosis older than 12 months and ICRB A/B/C were associated with better EFES. No second malignancies or ototoxicities were reported after a follow-up of median 3.1 years after diagnosis of retinoblastoma (range 0.1-6.9 years). CONCLUSIONS Despite omitting cyclophosphamide, the EFES was higher after VEC chemotherapy that contains higher doses of carboplatin compared to CyVEC. The major risk factor for enucleation was advanced ICRB tumor grouping. Randomized clinical trials on efficacy and side effects of eye-preserving chemotherapy are required to tailor treatment protocols for retinoblastoma patients.

Effect of Intravenous Chemotherapy Regimen on Globe Salvage Success Rates for Retinoblastoma Based on Disease Class-A Meta-Analysis. Cancers (Basel) 2021; 13:cancers13092216. [PMID: 34066325 PMCID: PMC8125212 DOI: 10.3390/cancers13092216] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 04/17/2021] [Accepted: 04/27/2021] [Indexed: 02/08/2023] Open
Abstract
Simple Summary Intravenous chemoreduction (IVCRD) has been the standard of care for treatment of retinoblastoma (RB). Since survival rates exceed 95–98%, the goals of treatment have now shifted to emphasize eye salvage and vision preservation in addition to patient survival. Consequently, there has been a shift towards combining standard IVCRD with intravitreal chemotherapy or altogether replacing IVCRD with intra-arterial chemotherapy. As more data from intravitreal chemotherapy and intra-arterial chemotherapy are being published, there are claims of improved globe salvage rates resulting in more widespread use of these newer treatment modalities. However, there are no published randomized controlled trials comparing these to IVCRD head-to-head. To evaluate the relative efficacy of these new therapies, it is critical to determine the true success rates of IVCRD regimens alone. Therefore, it is both timely and essential to determine the baseline IVCRD success rates so that an evidence-based assessment of new and emerging therapies can be determined. Abstract To evaluate the relative efficacy of novel retinoblastoma treatments, eye classification-specific success rates for current standard-of-care intravenous chemotherapy regimens must be known. This meta-analysis included studies if: (1) patients received intravenous chemotherapy for retinoblastoma, (2) globe salvage data was reported, (3) only intravenous chemoreduction (with/without local consolidation) was used. The outcome measure was globe salvage success without need for salvage radiotherapy, subdivided by disease classification and chemotherapy regimen. Data from 27 studies (1483 eyes) were pooled. By Reese–Ellsworth classification, globe salvage rates were 85% (95%CI:73–92%) for Group I, 78% (95%CI:70–85%) for Group II, 68% (95%CI:56–78%) for Group III, 47% (95%CI:34–60%) for Group IV, and 35% (95%CI:26–45%) for Group V (Va: 35% [95%CI:21–54%]; Vb: 42% [95%CI:29–56%]; those without sub-classification: 31% [95%CI:19–47%]). By International Classification, globe salvage rates were 93% (95%CI:80–97%) for Group A, 83% (95%CI:73–89%) for Group B, 73% (95%CI:54–86%) for Group C, 40% (95%CI:31–51%) for Group D, and 19% (95%CI:5–50%) for Group E. Standard carboplatin-etoposide-vincristine out-performed two-drug regimens (odds ratio (OR) = 1.9 (95%CI:1.3–3.0) for Groups I-IV and OR = 2.1 (95%CI:1.3–3.4) for Group V; p = 0.002 for each). For eyes with diffuse vitreous seeds (Vb), an enhanced regimen out-performed standard chemotherapy (OR = 2.4 [95%CI:1.3–4.7]; p = 0.004). In conclusion, two-drug regimens were less effective for all eyes, whereas enhanced regimens were more effective for eyes with vitreous seeds. Novel therapies can now be compared to these baseline globe salvage rates.

Abstract
Retinoblastoma is lethal by metastasis if left untreated, so the primary goal of therapy is to preserve life, with ocular survival, visual preservation and quality of life as secondary aims. Historically, enucleation was the first successful therapeutic approach to decrease mortality, followed over 100 years ago by the first eye salvage attempts with radiotherapy. This led to the empiric delineation of a window for conservative management subject to a "state of metastatic grace" never to be violated. Over the last two decades, conservative management of retinoblastoma witnessed an impressive acceleration of improvements, culminating in two major paradigm shifts in therapeutic strategy. Firstly, the introduction of systemic chemotherapy and focal treatments in the late 1990s enabled radiotherapy to be progressively abandoned. Around 10 years later, the advent of chemotherapy in situ, with the capitalization of new routes of targeted drug delivery, namely intra-arterial, intravitreal and now intracameral injections, allowed significant increase in eye preservation rate, definitive eradication of radiotherapy and reduction of systemic chemotherapy. Here we intend to review the relevant knowledge susceptible to improve the conservative management of retinoblastoma in compliance with the "state of metastatic grace", with particular attention to (i) reviewing how new imaging modalities impact the frontiers of conservative management, (ii) dissecting retinoblastoma genesis, growth patterns, and intraocular routes of tumor propagation, (iii) assessing major therapeutic changes and trends, (iv) proposing a classification of relapsing retinoblastoma, (v) examining treatable/preventable disease-related or treatment-induced complications, and (vi) appraising new therapeutic targets and concepts, as well as liquid biopsy potentiality.

Clinical and genetic associations for carboplatin-related ototoxicity in children treated for retinoblastoma: A retrospective noncomparative single-institute experience. Pediatr Blood Cancer 2018; 65:e26931. [PMID: 29350448 DOI: 10.1002/pbc.26931] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2017] [Revised: 11/22/2017] [Accepted: 11/24/2017] [Indexed: 12/31/2022]
Abstract
BACKGROUND Children with retinoblastoma treated with carboplatin chemotherapy risk moderate to severe, irreversible hearing loss. Based on published evidence, we hypothesized that ototoxicity risk is associated with clinical parameters and variants in candidate genes in drug metabolism pathways (methyltransferases [thiopurine S-methyltransferase, TPMT] and [catechol-O-methyltransferase, COMT], and drug transporter ABCC3). PROCEDURE We retrospectively reviewed clinical records of patients with retinoblastoma treated with carboplatin chemotherapy regarding age (at diagnosis and chemotherapy initiation), chemotherapy sessions (cycles number, drug doses, and cumulative carboplatin dose), and hearing loss (defined as ototoxicity ≥grade 2 by at least one classification system). Blood samples were genotyped for genetic variants in TPMT (rs12201199, rs1800460), COMT (rs4646316, rs9332377), and ABCC3 (rs1051640) by quantitative PCR and confirmed by allele-specific PCR. Univariate statistical tests, receiver-operating characteristic analysis, and Kaplan-Meier curves were used to examine the association between hearing loss, clinical factors, and variants in candidate genes. RESULTS Audiometric data and stored DNA were available for 71 patients with retinoblastoma (88% carried an RB1 pathogenic variant allele). Median carboplatin cumulative dose was 1,400 mg/m2 (260-5,148 mg/m2 ). Ototoxicity occurred in 18 patients (25%), strongly associated with age at diagnosis (P = 0.01) and age at chemotherapy initiation (OR = 4.99, P = 0.008). The highest likelihood ratio of hearing loss was associated with chemotherapy initiation <4.25 months of age. Ototoxicity was not associated with any tested genetic variants. CONCLUSIONS We observed a 25% prevalence of ototoxicity in patients with retinoblastoma treated with carboplatin, higher than previously published. Age at chemotherapy initiation was associated with carboplatin-induced ototoxicity, with children <4.25 months of age at highest risk.

Abstract
BACKGROUND AND OBJECTIVE To describe the ocular toxicity of intravitreal carboplatin and etoposide phosphate (VP16P) in Dutch-Belted rabbits. MATERIALS AND METHODS Twenty-two adult male Dutch-Belted rabbits (Cohort 1) each received a single, bilateral intravitreal injection (0.05 mL). For Cohort 1, safety was assessed via electroretinograms (ERGs) and ocular examination. Of nine total groups in Cohort 1, the first five received the following single agents: Group 1: normal saline; Group 2: VP16P 75 µg; Group 3: VP16P 100 µg; Group 4: carboplatin 4 µg; and Group 5: carboplatin 8 µg. Groups 6 through 9 received the following combination of carboplatin/ VP16P, respectively: Group 6: 8 µg/75 µg, Group 7: 8 µg/50 µg, Group 8: 4 µg/50 µg, and Group 9: 2 µg/25 µg. Cohort 2 consisted of 15 Dutch-Belted rabbits in seven groups (Groups 10 through 16), each receiving a single, bilateral intravitreal injection. For Cohort 2, safety was assessed via histopathology. RESULTS Groups 2 through 8 demonstrated a statistically significant decrease (relative to Group 1) in at least one ERG waveform amplitude obtained 4 weeks postinjection (P < .05). Group 9 (carbo 2 µg/VP16P 25 µg) did not manifest ERG toxicity. Fundoscopic toxicity consisted of slight-to-moderate attenuation of vessels in rabbits receiving doses above carbo 4 µg/VP16P 50 µg. Histopathologic retinal toxicity (Cohort 2) was dose-dependent, ranging from full-thickness atrophy in rabbits receiving the highest dose to normal in rabbits receiving carbo 2 µg/VP16P 25 µg. CONCLUSIONS Combined carboplatin and VP16P may be compatible for intravitreal injection therapy, and a single dose of 2 µg/25 µg appears to be safe in a rabbit model. These agents may be a safer alternative to intravitreal melphalan (Alkeran; GlaxoSmithKline, Brentford, United Kingdom) for the treatment of vitreous seeds in retinoblastoma.

Abstract
OBJECTIVES This study examined the recent trend in use and costs of antineoplastic agents for treatment of eye malignancies in Taiwan from 2009 to 2012. We also forecasted use and costs of targeted therapies up to and including year 2016 based on the current patterns. DESIGN Retrospective observational study focusing on the usage of targeted therapies for treatment of eye malignancy. SETTING The monthly claims data for eye malignancy-related antineoplastic agents were retrieved from Taiwan's National Health Insurance Research Database (2009-2012). MAIN OUTCOME MEASURES We calculated the number of prescriptions and costs for each class of medications, and analysed their time trends. In addition, using a time series design with ARIMA models, we estimated the market share by prescription volume and the proportion of costs for targeted therapies for year 2016. RESULTS The market share by prescription volume of targeted therapies grew from 1.56% in 2009 to 9.98% in 2012 among all antineoplastic agents, and the proportion of costs for targeted therapies rose from 15.12% in 2009 to 58.88% in 2012. Especially, the proportion of costs for protein kinase inhibitors grew from 25.62% to 45.28% among all antineoplastic agents between 2010 and 2012. The market share by prescription volume and the proportion of costs for targeted therapies for treatment of eye malignancies were predicted to reach 27.33% and 91.39% by the fourth quarter in 2016, respectively. CONCLUSIONS This is the first study that examined and forecasted use and costs of targeted therapies for treatment of eye malignancies in Taiwan. Our findings indicate that, compared with other classes of drugs, targeted therapies are having a more and more relevant share among all treatment strategies for eye malignancies in Taiwan, and due to their high costs they are likely to cause great economic burden.

Abstract
PURPOSE The aim is to report the 10-year retrospective experience of systemic chemotherapy for a population-based group of patients with hereditary retinoblastoma at a national referral centre. The outcomes include control rates, treatment side-effects, adjuvant therapy, failure rate, survival, secondary cancers and visual acuity. METHODS All patients (n = 24, 46 eyes) diagnosed with retinoblastoma and treated with systemic chemotherapy at a national referral centre during 2001-2011 were included. Data were extracted from medical records. RESULTS The patients were followed for a mean of 60 months (range 13-144). Four-six cycles of VEC was administered to all newly diagnosed group B/C/D/E eyes with bilateral disease and 83% (38 of 46) responded to the treatment. None of the patients discontinued chemotherapy because of adverse reactions. Altogether 26% (12 of 46) of the eyes received second-line therapy (other than thermotherapy, cryotherapy and chemotherapy). The failure rate was 35% (16 of 46) and mortality rate 0%. None of the patients developed CNS manifestations (metastases or trilateral retinoblastoma). One of the patients developed a second primary tumour (osteosarcoma) 4 years following retinoblastoma diagnosis. Altogether 17% (4 of 24) patients received radiation therapy, 28% (13 of 46) of the eyes had to be enucleated, and one patient underwent bilateral enucleation. The age-correlated visual acuity was mean of 73% of expected visual acuity. CONCLUSION Group A/B retinoblastomas have a distinct chemotherapy response, while group C/D/E tumours do not respond as well. The success rate was 65%; while patients have a good prognosis for life, approximately one-third of all hereditary cases received radiation therapy or underwent enucleation.

Abstract
PURPOSE To analyze the clinical manifestations and treatment outcomes for patients with retinoblastoma in Singapore from 1997 to 2010. METHODS Medical records of 51 patients (67 eyes) diagnosed as having retinoblastoma were analyzed. Data on laterality, genetics, presentation, disease severity, treatment, and prognosis were collected. RESULTS The mean age of presentation was 25.7 ± 19.9 months. Sixteen (31.4%) of the patients had bilateral disease, of whom 2 had an associated pineal tumor. Leukocoria was the most common sign. Two had metastasis at diagnosis. Only 3 patients (5.9%) had a family history. Using the International Intraocular Retinoblastoma Classification, 6.0% were Group A, 6.0% were Group B, 3.0% were Group C, 38.8% were Group D, and 49.2% were Group E. Chemotherapy and focal therapy were administered for 4 of 35 (12.9%) patients with unilateral retinoblastoma (50% had successful globe preservation) and 13 of 16 (81.3%) patients with bilateral retinoblastoma (42.3% had successful globe preservation). Overall, globe preservation was achieved in 100% of Groups A, B, and C, and 23.1% of Group D cases. The 5-year survival rate overall, for unilateral retinoblastoma, and for bilateral retinoblastoma was 91%, 97%, and 76% respectively. CONCLUSION The overall 5-year survival rate is comparable to international data in most developed countries. However, most patients presented with advanced disease, making the rate of globe preservation lower than in some developed countries. Better education of the public and healthcare professionals may increase awareness and enable early detection of the disease.

Abstract
Retinoblastoma is a deadly eye cancer in children, leading to death in 50%-70% of children in undeveloped nations who are diagnosed with it. This malignancy is the most common intraocular tumor in childhood worldwide. The good prognosis in developed nations is related to early detection and advanced treatments. With the advent of intraarterial chemotherapy, neurosurgeons have taken a central role in the treatment of this pediatric condition. Intraarterial chemotherapy is a novel treatment for retinoblastoma whereby chemotherapeutic agents are precisely delivered into the ophthalmic artery, minimizing systemic toxicity. This procedure has shown impressive results and has allowed a dramatic decrease in the rate of enucleation (eye removal) in advanced and refractory retinoblastoma. Recent reports have raised some concerns about the risk of ocular vasculopathy, radiation-related toxicity, and the potential for metastatic disease after intraarterial chemotherapy. In the authors' experience of more than 3 years, tumor control is excellent with globe salvage at 67% and vascular events less than 5%, mostly related to improvement in technique. The role of this novel approach in the management of retinoblastoma has yet to be defined. As more centers are adopting the technique, the topic will decidedly become the focus of intensive future research. In this paper, the authors review and discuss current data regarding intraarterial chemotherapy for retinoblastoma.

Abstract
Many advances in the field of management of retinoblastoma emerged in the past few years. Patterns of presentation of retinoblastoma in the Middle East region differ from Western community. The use of enucleation as a radical method of eradicating advanced disease is not easily accepted by patient's family. We still do see stage E, failed or resistant retinoblastoma and advanced extraocular disease ensues as a result of delayed enucleation decision. In this review, we discuss updates in management of retinoblastoma with its implication on patients in our part of the world. Identifying clinical and high risk characteristics is important prognostically and are discussed for further management of retinoblastoma cases.

Occurrence of sectoral choroidal occlusive vasculopathy and retinal arteriolar embolization after superselective ophthalmic artery chemotherapy for advanced intraocular retinoblastoma. Retina 2011; 31:566-73. [PMID: 21273941 DOI: 10.1097/iae.0b013e318203c101] [Citation(s) in RCA: 87] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
BACKGROUND Superselective ophthalmic artery chemotherapy (SOAC) has recently been proposed as an alternative to intravenous chemoreduction for advanced intraocular retinoblastoma. Preliminary results appear promising in terms of tumor control and eye conservation, but little is known regarding ocular toxicity and visual prognosis. In this study, we report on the vascular adverse effects observed in our initial cohort of 13 patients. METHODS The charts of 13 consecutive patients with retinoblastoma who received a total of 30 injections (up to 3 injections of a single agent per patient at 3-week interval) of melphalan (0.35 mg/kg) in the ophthalmic artery between November 2008 and June 2010 were retrospectively reviewed. RetCam fundus photography and fluorescein angiography were performed at presentation and before each injection. Vision was assessed at the latest visit. RESULTS Enucleation and external beam radiotherapy could be avoided in all cases but one, with a mean follow-up of 7 months. Sectoral choroidal occlusive vasculopathy leading to chorioretinal atrophy was observed temporally in 2 eyes (15%) 3 weeks to 6 weeks after the beginning of SOAC and retinal arteriolar emboli in 1 eye 2 weeks after injection. There was no stroke or other clinically significant systemic side effects except a perioperative transient spasm of the internal carotid artery in one patient. Vision ranged between 20/1600 and 20/32 depending on the status of the macula. CONCLUSION Superselective ophthalmic artery chemotherapy was effective in all patients with no stroke or other systemic vascular complications. Unlike intravenous chemoreduction, SOAC is associated with potentially sight-threatening adverse effects, such as severe chorioretinal atrophy secondary to subacute choroidal occlusive vasculopathy or central retinal artery embolism, not to mention the risk of ophthalmic artery obstruction, which was not observed in this series. Further analysis of the risks and benefits of SOAC will define its role within the therapeutic arsenal. Meanwhile, we suggest that SOAC should be given in one eye only and restricted to advanced cases of retinoblastoma, as an alternative to enucleation and/or external beam radiotherapy.

Abstract
The transfection efficiency of wild-type p53 ( wtp53) was investigated in retinoblastoma (RB) Y79 cells using an ultrasound microbubble technique. A human RB nude mouse xenograft tumour model was also used to investigate whether this technique could deliver wtp53 into solid tumours. Reverse transcription–polymerase chain reaction (RT–PCR) demonstrated that wtp53 was successfully transfected into Y79 cells in the plasmid with microbubbles and ultrasound group and in the plasmid with liposomes group, but not in the plasmid with ultrasound group or in the untreated control group. Flow cytometry showed that apoptosis was highest in the microbubbles and ultrasound group (25.58%) compared with the plasmid with liposomes group (19.50%), and the other two groups (< 10%). RT–PCR also showed that the wtp53 gene was successfully transfected into solid tumours in the plasmid with microbubbles and ultrasound group. This study provides preliminary evidence in support of a potential new approach to RB gene therapy.

Abstract
PURPOSE To compare the expression of pregnane xenobiotic receptor and certain multi-drug resistance proteins in retinoblastoma. METHODS Using tissue microarray analyses, we studied 62 pathology specimens for expression of pregnane xenobiotic receptor, multi-drug resistance 1/P glycoprotein, multi-drug resistance proteins 1, 2, and 4, and breast cancer resistant protein. RESULTS Comparing tumors treated with primary enucleation with tumors treated with chemotherapy and/or radiation showed no significant differences in the expression of multi-drug resistance proteins or pregnane xenobiotic receptor. Pregnane xenobiotic receptor was correlated with multi-drug resistance protein 2 expression (p < 0.001). CONCLUSION Our results indicate selection, rather than induction, of chemoresistant cells as a cause for treatment failure in managing retinoblastoma with primary systemic chemotherapy.

Abstract
BACKGROUND Carboplatin plays an important role in the conservative management of retinoblastoma, but is associated with risk of ototoxicity in these young children whose sensory prognosis may be also compromised by their loss of vision. This retrospective study analyzed the impact of carboplatin on hearing in the context of conservative management of children with retinoblastoma. METHODS Data for 175 children treated at the Institut Curie between 1994 and 2002 were analyzed. RESULTS Median age at diagnosis was 8 months (0-60). Carboplatin was administered on 3 days (200 mg/m(2)/day) or 5 days (160 mg/m(2)/day) with etoposide and with diode-laser therapy at the dose of 560 mg/m(2) (chemothermotherapy). Median cumulative dose of carboplatin was 2,880 mg/m(2) (560-6,160). Ototoxicity was investigated by pure-tone audiometry and scored by Brock's grading scale before and after treatment. The median follow-up of hearing assessment was 5 years (1.8-11). Ototoxicity was detected in 8 children: 3 grade 1, 1 grade 2, and 2 grade 4. The two patients with grade 4 hearing-loss required a hearing aid. Two children developed bilateral high frequency hearing-loss, considered to be secondary to carboplatin but with less than Brock grade 1. Ototoxicity was observed for a median cumulative dose of carboplatin of 3,120 mg/m(2) (1,200-5,830). Only one child developed ototoxicity during treatment. All other cases were discovered after the last dose of carboplatin with a median interval of 3.7 years (0-7.6). No other risk factor for ototoxicity was able to account for these lesions. CONCLUSION Children receiving carboplatin require long-term audiometric follow-up.

Abstract
BACKGROUND Retinoblastoma is the most common intraocular tumor of childhood. Vision salvage rates in advanced cases are less than ideal, and the optimal treatment for intraocular retinoblastoma has not been established. We report the results of an institutional retinoblastoma treatment trial to determine the vision salvage rates and toxicity of a regimen combining carboplatin and etoposide with focal retinal therapy. PROCEDURE Twenty-nine patients diagnosed with retinoblastoma in 48 eyes were treated between 1992 and 2004 with at least six cycles of carboplatin and etoposide combined with focal retinal therapy. RESULTS The response rate of eyes after six cycles of chemotherapy was 85.4%. Twenty-two eyes were enucleated, but only seven eyes received EBRT. The vision salvage rate without EBRT was 82.6% for eyes with Reese-Ellsworth (R-E) groups I-IV tumors and 20% for eyes with R-E group V tumors. The vision salvage rate without EBRT for eyes with Murphree groups A and B tumors was 77.3% but was only 26.9% for eyes with groups C and D tumors. Acute side effects were minimal. CONCLUSIONS The combination of carboplatin and etoposide with focal therapy is a well-tolerated regimen that has acceptable vision salvage rates for R-E groups I-IV and Murphree groups A and B retinoblastoma. This combination avoids the use of EBRT and the toxicity of additional chemotherapy agents. However, patients with R-E group V and Murphree groups C and D retinoblastoma have poorer outcomes and require more intensive therapy.

Abstract
PURPOSE To report the incidence of new tumor formation in hereditary retinoblastoma patients treated with primary systemic chemotherapy. DESIGN Noncomparative retrospective case series. PARTICIPANTS Fifty-eight consecutive patients with hereditary retinoblastoma treated with primary systemic chemotherapy. METHODS The charts of 58 consecutive patients with hereditary retinoblastoma treated between January 1996 and August 2005 were reviewed. Data extracted included gender, age at diagnosis, family history of retinoblastoma, laterality of disease, tumors per eye, Reese-Ellsworth grouping of affected eyes, starting and ending dates for chemotherapy, number of cycles of chemotherapy, chemotherapy regimen, need for external beam radiotherapy and/or enucleation, and development and location (macula, midzone, and periphery) of new tumors after the start of systemic chemotherapy. MAIN OUTCOME MEASURE New tumor formation after treatment with primary systemic chemotherapy. RESULTS Of the 58 patients, 48 had bilateral involvement at diagnosis. Median age at diagnosis was 6.6 months. Thirteen patients had a positive family history. Of the eyes with tumor (n = 106) at diagnosis, 52 (49%) were in Reese-Ellsworth groups I to III, whereas 54 (51%) were in group IV or V. Seven patients (12%) with a median age of 1.6 months at diagnosis formed 36 new tumors in 11 eyes after the start of chemotherapy. Median time from initiation of chemotherapy to detection of the first new tumor was 3 months (range, 1-15). Cumulative incidence of new tumor formation at 2 years was 10+/-3%. An age of <6 months at diagnosis, family history of retinoblastoma, and Reese-Ellsworth grouping of I to III were found to correlate significantly with an increased incidence of new tumor formation (P<0.001, P<0.001, and P = 0.021, respectively). Median follow-up for all patients was 5 years (range, 1-10.1). CONCLUSION New tumors continue to form in patients with hereditary retinoblastoma despite treatment with primary systemic chemotherapy. Younger patients and those with a positive family history are more likely to have new tumors formed. However, chemotherapy may impact small previously undetected lesions by slowing their growth and facilitating later focal consolidation.

Abstract
OBJECTIVE To determine tumor control rates, complication rates, and visual acuity (VA) for patients with macular retinoblastoma undergoing systemic chemotherapy and foveal diode laser ablation. DESIGN Noncomparative retrospective case series. PARTICIPANTS All patients with retinoblastoma in the macula at the Bascom Palmer Eye Institute between 1991 and 2004 were evaluated. Patients included in the study were managed by the same clinician with a planned therapeutic strategy. METHODS Patients with Reese-Ellsworth groups I to IV disease underwent 4 to 9 cycles of systemic chemotherapy with vincristine, etoposide, and carboplatin, and patients with group V disease underwent 6 to 10 cycles with or without cyclosporine. All tumors underwent repetitive diode laser ablation (2-24 sessions) applied to the foveal and extrafoveal portions of tumors at each visit until tumors were deemed inactive for at least 6 months. MAIN OUTCOME MEASURES Recurrence requiring external beam radiation therapy or enucleation; VA; and complications including iris atrophy, peripheral focal lens opacity, peripheral anterior synechiae, and foveal neovascular membrane. RESULTS Forty-four eyes of 33 patients were treated. Eyes were classified as Reese-Ellsworth group I (1 [2%]), II (6 [12%]), III (3 [7%]), IV (5 [9%]), or V (29 [67%]). Thirty-eight eyes (86%) had successful tumor control and avoided enucleation at a median follow-up of 36 months. At 3 years, tumor control rates were 100% for Reese-Ellsworth groups I to IV and 83% for group V. All eyes requiring enucleation were in Reese-Ellsworth group V. No eyes required external beam radiation. The most common complications were iris atrophy (61%) and focal lens opacity (14%). Strabismus was noted in 16% of eyes. Snellen VA measured 20/40 or better in 36% of eyes, 20/80 or better in 57%, and 20/400 or better in 86%. An increasing number of laser applications and chemotherapy cycles was not associated with decreased VA, strabismus, or development of an afferent pupillary defect but was associated with development of local complications. CONCLUSIONS A unique approach to the application of diode laser therapy characterized by repetitive foveal treatments and aggressive chemotherapy resulted in tumor control rates that exceed those previously published. Furthermore, despite laser application directly to the fovea, 57% of patients retained 20/80 or better vision.

Abstract
OBJECTIVE Our objective for this study was to examine the impact of the modern management of intraocular retinoblastoma on the patient and the family. METHODS This study comprises a retrospective, noncomparative case series of 25 consecutive patients with multifocal, intraocular retinoblastoma that was treated with primary systemic chemotherapy. Medical charts were reviewed, and the following data were extracted: patients' age and gender, laterality of disease, and Reese-Ellsworth classification of each eye as well as the number of central venous lines placed, cycles of chemotherapy received, outpatient appointments, examinations under anesthesia, focal therapies administered, computed tomography/MRI, radiation treatments, anesthetic procedures administered, and miles traveled. RESULTS Twenty patients with bilateral and 5 with unilateral intraocular retinoblastoma (median age: 9.3 months) had 895 outpatient appointments and underwent 698 examinations under anesthesia with 230 focal therapies, 347 days of radiotherapy, 226 computed tomography scans/MRIs, and 38 central venous line placements. A total of 1272 anesthetic procedures (median: 50) were performed with no major complication. In all, patients traveled 822312 miles (median: 22214 miles) to receive their care. The median follow-up was 82 months. CONCLUSIONS Successful retinoblastoma management requires close surveillance, aggressive consolidation, and numerous anesthetic procedures, all of which the patients and the families must endure. There is a significant impact on the patient, the family, and hospital resources.

Abstract
To evaluate the efficacy of conservative management of intraocular retinoblastoma with chemoreduction combined with local therapy with or without plaque radiation in the preservation of the eye, and avoidance of external beam radiation therapy (EBRT) (success rate). From 1995 to 2000, 84 newly diagnosed patients with intraocular retinoblastoma were admitted to the Pediatric Department of the Hospital do Cancer A.C. Camargo, São Paulo, Brazil. All children were treated with 2 to 6 cycles of chemotherapy (carboplatin, vincristine, and etoposide) plus local therapy (cryotherapy, laser photocoagulation, and thermotherapy), or plaque radiation therapy during and/or after the chemotherapy. The Mann-Whitney test was used to compare means of quantitative variables. The chi test or the Fisher exact test were employed to verify the association between the outcome and the independent variables. For all tests alpha=5% was adopted. Success rate was higher for patients with bilateral tumors (54%) than for children with unilateral tumors (19%) (P=0.003). For patients with Reese-Ellsworth stages I, II, and III, no statistically significant differences in the success rates were noted in the group of unilateral (50%) and bilateral tumors (79.1%) (P=0.179). Among children with Reese-Ellsworth stages IV and V, the success rate was significantly higher for patients with bilateral tumors (40.7%) than for those with unilateral (0%) (P=0.012). Chemoreduction combined with local therapy, with or without plaque radiotherapy, is efficacious in avoiding enucleation and the use of external beam radiation therapy for children with intraocular retinoblastoma.

Abstract
PURPOSE To evaluate vincristine and carboplatin with intensive focal treatments in the management of intraocular retinoblastoma. DESIGN Noncomparative, retrospective interventional case series. METHODS SETTING Institutional. PATIENT POPULATION Sixteen patients (11 bilateral, 5 unilateral) with intraocular retinoblastoma. Interventional procedures: Patients were treated with eight courses of vincristine and carboplatin. Intensive focal treatments were administered after two courses of chemotherapy. MAIN OUTCOME MEASURES Avoidance of external beam radiotherapy (EBRT) and eye survival. RESULTS Twenty eyes (74.1%) were classified as Reese-Ellsworth Group V. All eyes responded to chemotherapy. With a median follow-up of 23 months (range 10 to 33 months) and a median of 5.5 focal treatments per eye (range 0 to 19 treatments), ocular survival was 81%. Eight eyes (30%) in five patients received EBRT. CONCLUSIONS Vincristine and carboplatin combined with intensive focal treatments is an effective regimen for patients with intraocular retinoblastoma. This treatment regimen has outcomes comparable to those of more toxic regimens and merits further evaluation.

Abstract
PURPOSE To evaluate the response/recurrence rate and the outcome in intraocular retinoblastoma treated with chemoreduction and focal therapy, the authors performed a retrospective review of their patients. METHODS The series included 46 newly diagnosed patients with unilateral or bilateral intraocular retinoblastoma (58 eyes) receiving carboplatin/etoposide chemotherapy associated with focal therapy (laser or cryotherapy). The mean follow-up was 53 months (range 11-125). RESULTS Fifty-one eyes (88%) presented with complete response after four to eight courses of chemotherapy combined with focal treatment. The response rate was 100% in group 1, 94% in group 2, 100% in group 3, 83% in group 4, and 70% in group 5 (5 vs. 1-4, P < 0.03; 5-4 vs. 1-3, P < 0.025). Twenty-nine eyes (57%) relapsed after a mean of 7 months (range 2-36). The relapse rate was 30% in group 1, 27.% in group 2, 67% in group 3, 80% in group 4, and 100% in group 5 (5 vs. 1-4, P < 0.001; 4-5 vs. 1-3, P < 0.001). Seven of 18 cases achieved a second complete response with further conservative treatment (total courses 8-14). Twenty-nine eyes (50%) were treated without external-beam radiotherapy or enucleation: 90% in group 1, 69% in group 2, 67% in group 3, 33% in group 4, and 6% in group 5 (5 vs. 1-4, P < 0.01; 5-4 vs. 1-3, P < 0.001). Ten eyes (17%) required external-beam radiotherapy and 21 eyes (36%) enucleation. The ocular salvage rate was 67%. CONCLUSIONS Although all groups of patients with intraocular retinoblastoma responded to carboplatin/etoposide chemotherapy associated with focal therapy, all the cases in group 5 relapsed. This approach is questionable in group 5, in which could be justified to delay aggressive treatment in a very young child.

Abstract
BACKGROUND/AIM Retinoblastoma is the commonest primary intraocular tumour in children. Chemotherapy now plays a big part in the treatment of these tumours. There is not much information about the role of the multidrug resistance proteins (MDR)-P-glycoprotein (P-gp) and vault protein lung resistance protein (LRP)-in retinoblastoma. The authors investigated the expression of P-gp and LRP in retinoblastoma and correlated them clinicopathologically. METHODS Among 60 retinoblastomas, 40 tumours were not subjected to preoperative or postoperative chemotherapy and 20 tumours were subjected to postoperative chemotherapy. In this cohort 27 tumours had no invasion and 33 tumours had invasion of choroid, optic nerve, and orbit. P-gp and LRP expression were studied by immunohistochemistry. Immunoanalysis was done semiquantitatively. RESULTS Among the 60 tumours P-gp was expressed in 23 (38%) tumours and LRP was expressed in 35 (58%). P-gp was expressed in 11/27 (40%) tumours with no invasion and in 12/33 (36%) tumours with invasion. LRP was expressed in 15/27 (55%) tumours with no invasion and in 20/33 (60%) tumours with invasion. Both P-gp and LRP were negative in three tumours with invasion, which had later developed bone marrow metastasis. There was no correlation between P-gp and LRP expression with invasion, differentiation and laterality of the tumours and response to treatment. CONCLUSION Retinoblastoma expresses P-gp and LRP intrinsically before chemotherapy and none of these proteins predicted the response to chemotherapy. Thus, further studies are needed to understand the significance of the expression of the P-gp and LRP proteins in retinoblastoma.

Abstract
PURPOSE To evaluate the causes of chemoreduction failure in retinoblastoma and to analyze the associated factors for eventual treatment with external beam radiotherapy and enucleation. DESIGN Prospective noncomparative case series. PARTICIPANTS Seventy-one patients with 105 eyes with intraocular retinoblastoma that underwent chemoreduction therapy between October 1998 and January 2003. INTERVENTION A 6-treatment cycle of chemoreduction therapy with vincristine, etoposide, and carboplatin was administered at monthly intervals. Unresponsive disease was defined as persistence of retinal tumors, vitreous seeds, or subretinal seeds after the second treatment cycle, with no appreciable sign of regression. Eyes with unresponsive disease were enucleated after the second treatment. Eyes that responded to chemoreduction therapy received focal treatment, including indirect laser photocoagulation, transpupillary thermotherapy, cryotherapy, and ruthenium 106 episcleral plaque radiotherapy after the second chemoreduction treatment, if necessary, to achieve complete tumor regression. Recurrence was defined as the regrowth of retinal tumors, vitreous or subretinal seeds after an initial favorable response, and regression. Recurrent retinal tumor, vitreous seeds, or subretinal seeds were treated with focal treatments and 2 to 3 additional chemoreduction treatments. When these methods failed or were not applicable, external beam radiotherapy and/or enucleation was administered. MAIN OUTCOME MEASURES The use of external beam radiotherapy and enucleation for chemoreduction failure, which was defined as unresponsive or recurrent disease. RESULTS The mean follow-up was 25.7 months (range: 6-49). Ten of 105 eyes (9.5%) with unresponsive disease were enucleated after the second treatment. Of the remaining 95 eyes, 42 (44.2%) developed recurrence after chemoreduction. Recurrent disease failing to be treated successfully by other methods was treated with external beam radiotherapy in 26 of 95 eyes (27.4%) and enucleation in 22 of 95 eyes (23.2%). External beam radiotherapy was successful in preventing enucleation in 20 of 26 eyes (76.9%). Overall, the globe salvage rate was 69.5%, ranging from 36.1% for Reese-Ellsworth group V disease to 87.0% for groups I to IV disease. Histopathologically, 29 of 31 enucleated eyes (93.5%) had poorly differentiated or moderately differentiated retinoblastoma. Using multivariate logistic regression analysis, factors predictive of eventual treatment with external beam radiotherapy were female gender (P = 0.010), presence of subretinal seeds (P = 0.023), and a greater number of chemoreduction treatments (P = 0.027). By multivariate analysis, the factors associated with the need for eventual treatment with enucleation were recurrence of retinal tumors (P = 0.004), presence of vitreous seeds (P = 0.008), greater tumor thickness (P = 0.015), presence of subretinal fluid (P = 0.040), and older patient age (P = 0.042). CONCLUSIONS Chemoreduction failure in this article was defined as unresponsive or, more commonly, recurrent retinoblastoma. Older patient age, greater tumor thickness, presence of vitreous seeds and subretinal fluid at baseline, and retinal tumor recurrence after chemoreduction were factors associated with the need for enucleation.

Abstract
PURPOSE To determine the frequency and timing of new intraocular tumor formation in children with hereditary retinoblastoma initially treated with systemic carboplatin. DESIGN Retrospective, noncomparative case series. PARTICIPANTS This study included 34 children (57 eyes) with hereditary bilateral retinoblastoma initially treated with systemic carboplatin at the Robert M. Ellsworth Ophthalmic Oncology Center at NewYork-Presbyterian Hospital from 1994 through 2000. MAIN OUTCOME MEASURES New tumor formation after initial treatment with systemic carboplatin. RESULTS There were a total of 165 tumors in 57 eyes. There were 63 new tumors in 27 eyes (47%) after administration of systemic carboplatin, for a mean of 1.1 new tumors per eye. The mean patient age at time of new tumor presentation was 9 months, with 57% of new tumors developing within 4 months of carboplatin treatment. Kaplan-Meier analysis showed that children who were treated when younger than 6 months of age were more likely to have new tumors (60%) compared with those treated after 6 months of age (31%; P = 0.0182). CONCLUSIONS New intraocular tumors continue to develop after systemic carboplatin; most new tumors appeared within 4 months of treatment.

Abstract
PURPOSE To evaluate the efficacy of chemoreduction using vincristine and carboplatin in preventing or delaying external-beam radiotherapy (EBRT) or enucleation in patients with intraocular retinoblastoma. PATIENTS AND METHODS Twenty-five patients (43 eyes) with newly diagnosed intraocular retinoblastoma received primary treatment with eight courses of vincristine and carboplatin. Focal treatments were delayed until documentation of disease progression. Outcome measures for each eye were length of time to disease progression, avoidance or delay of EBRT, and globe survival. Event-free survival was defined as the length of time to EBRT or enucleation. RESULTS Disease in all eyes responded to chemotherapy and progressed in only two patients before completion of the eight courses of therapy. Disease in all but four eyes progressed and required focal treatments. Event-free survival estimates at 2 years were 59.2% +/- 12.0% for Reese-Ellsworth group I, II, and III eyes and 26.3% +/- 9.2% for group IV and V eyes. Nineteen eyes (44.2%) required EBRT and 13 eyes (30.2%) were enucleated. The ocular salvage rate was 83.3% for Reese-Ellsworth group I to III eyes and 52.6% for group IV and V eyes. For those patients receiving EBRT, the median time from enrollment to EBRT was 9.5 months (median age at EBRT, 21 months). CONCLUSION In combination with appropriate early intensive focal treatments, chemoreduction with vincristine and carboplatin, without etoposide, may be an alternative treatment for patients with early-stage intraocular retinoblastoma, although additional studies are needed. Patients with advanced intraocular disease require more aggressive treatments.

Abstract
AIM The role of neoadjuvant chemotherapy was studied when first line enucleation cannot be safely performed in unilateral extensive retinoblastoma (major buphthalmia or radiologically detectable optic nerve involvement). METHODS Six patients, referred for unilateral retinoblastoma, presented with major buphthalmia (two) or optic nerve invasion (four): they were treated by neoadjuvant chemotherapy using etoposide and carboplatin. RESULTS Good tumour response was observed in the two patients with buphthalmia and in three of four cases with optic nerve involvement. Meningeal progressive disease was observed in the last patient. The five patients without disease progression were then operated on: anterior enucleation in the patients with buphthalmia and enucleation via a double neurosurgical and ophthalmological approach with prechiasmatic optic nerve section in the other three cases. Postoperative chemotherapy was performed in these five patients. Local radiotherapy to the chiasmatic region and posterior part of the optic canal was necessary in only one patient. The non-operated patient died with disease progression 6 months after the diagnosis. The other five patients are alive with a follow up of 12, 15, 21, 36, and 40 months after stopping treatment. CONCLUSION Neoadjuvant chemotherapy can be useful in extensive unilateral retinoblastoma with buphthalmia and/or radiological optic nerve invasion at diagnosis.

Abstract
BACKGROUND/AIM The combination of chemotherapy and transpupillary thermotherapy, thermochemotherapy (TCT) has become an established part of the treatment plan in advanced retinoblastoma. The aim of this study was to identify safe indications, the complications as well as the limitations of this new treatment for retinoblastoma. METHODS Tumour response and side effects of TCT with an indirect laser ophthalmoscope (spot size about 400 micro m) in 55 tumours of 26 children with bilateral retinoblastoma were analysed. Using the Reese-Ellsworth classification system, nine of 35 eyes were classified as type I, 13 eyes as type II, 10 eyes as type III, and three eyes as type V. The mean age of the children was 0.74 (SD 0.61) years. The mean tumour height was 3.5 (2.3) mm with a mean diameter of 6.1 (4.1) mm. Treatment parameters were 4.3 (1.6) (median 5) thermochemotherapy sessions with a mean energy of 539 (211) mW and a mean duration of 13.5 (5.6) minutes. Chemotherapy courses (vincristine, etoposide, and carboplatin) were repeated every 3 weeks. The mean follow up period was 1.25 (0.6) years. RESULTS Local recurrence occurred in 21 tumours (38%), with a mean onset of 3.2 (2.9) months after TCT. The risk of tumour recurrence was correlated with tumour height. The recurrence rate was 17% for tumours with a height less than 2 mm, 37% for tumours with a height between 2 and 4 mm, and 63% for larger retinoblastomas. Multivariate analysis identified fish flesh regression after TCT (p = 0.0007) as the most important risk factor for tumour recurrence besides tumour height (p = 0.001) and the necessity of increased laser power during TCT sessions (p = 0.018). Complications during therapy included transient corneal opacification in two eyes (6%), focal iris atrophy (three eyes, 8.5%), peripheral lens opacity (two eyes, 6%), circumscribed transient retinal detachment (one eye, 3%) and diffuse choroidal atrophy (one eye, 3%). CONCLUSION TCT using an indirect laser ophthalmoscope with a spot size of about 400 micro m was efficient for retinoblastoma with a tumour height less than 4 mm. In larger tumours, the recurrence rate was unacceptably high. Fish flesh regression after TCT correlates with a higher rate of local tumour recurrence. Treatment related complications occurred in less than 9% of the treated eyes.

Abstract
BACKGROUND To assess the efficacy of chemotherapy (chemoreduction) plus local treatments as an alternative to external beam and enucleation for intraocular retinoblastoma. MATERIALS AND METHODS A prospective study was performed on 21 patients with retinoblastoma treated in our institution from September 1997 to December 2000 to study the ocular outcome of those 33 eyes. RESULTS There were 9 unilateral and 12 bilateral retinoblastoma cases. There were 12 eyes with Reese-Ellsworth group I-IV and 21 eyes with group V. Among 33 eyes, nine eyes (27%) were initially managed by enucleation. The remaining 24 eyes (73%) were initially treated with chemoreduction (maximum of six cycles of carboplatin, vincristine, etoposide) or chemothermotherapy. Among those 24 eyes, 20 were successfully treated with local treatments (thermotherapy plus cryotherapy in 16 eyes and thermotherapy plus cryotherapy plus (125)I plaque radiotherapy in 4 eyes), enucleation eventually underwent in two eyes and was proposed but refused in one child with bilateral group V retinoblastoma. With a median follow-up of 21 months, conservative management without external beam radiation was successful in all 12 eyes with group I-IV and in a total of 20/33 eyes (60%). Among the nine cases of unilateral retinoblastoma, eight were enucleated but among the 24 eyes with bilateral retinoblastoma, 19 (79%) were successfully treated with conservative therapy. CONCLUSIONS It may be possible to eradicate viable tumor in all eyes with Reese-Ellsworth group I-IV retinoblastoma by chemoreduction followed by local treatments. Although 8 out of 21 eyes (38%) with group V retinoblastoma may be salvaged after chemoreduction and local therapies, enucleation remained the treatment of choice in those eyes with total retinal detachment and diffuse vitreous seeding.

Abstract
AIMS To evaluate how tumour size, retinal location, and patient age affect the outcome of retinoblastoma foci treated with chemotherapy. METHODS Retrospective review of retinoblastoma foci treated with primary chemotherapy alone. Individual tumours were coded with regard to their largest basal diameter, location within the eye (macula, macula to equator, equator to ora serrata), and patient's age at diagnosis. Successfully treated tumours required no further intervention while those requiring additional treatment were coded as failures. RESULTS 56 (72%) tumours responded successfully to chemotherapy alone while 22 (28%) required additional therapy. 26 of 31 macular tumours (84%) and 30 of 47 extramacular tumours (64%) responded to chemotherapy (p <0.060). Relative to size, 46 of 60 tumours (77%) greater than 2 mm in basal diameter were successfully treated with chemotherapy, while only 10 of 18 tumours (56%) less than or equal to 2 mm responded (p <0.088). Among the eight tumour foci diagnosed in children less than 2 months of age, five (63%) failed to respond to chemotherapy alone (p <0.032). CONCLUSION Retinoblastoma is more likely to respond to primary chemotherapy if it is located in the macula and if the patient is older than 2 months of age. Tumours measuring less than 2 mm in diameter may be less responsive to this treatment.

Abstract
BACKGROUND Orbital growth retardation, after enucleation and/or external beam radiation for retinoblastoma (RB), is a serious late effect. We measured orbital volumes of RB survivors treated at Hadassah University Hospital, Jerusalem, between 1980-1998. PROCEDURE Forty-five orbits of 28 children with RB (17 bilateral, 11 unilateral) were examined. Thirty-six orbits were irradiated, 19 enucleated, and 10 both enucleated and irradiated. The orbital volumes were calculated from a three-dimensional orbital CT reconstruction. The orbits of RB survivors were compared to age-matched controls. RESULTS The mean age at diagnosis was 13 months, mean follow-up time was 56 months. The mean volume of RB orbits (14.4 cc) was statistically significantly smaller than control orbits (17.8 cc). There was no difference between the mean volume of orbits treated with enucleation, irradiation or both. The orbital volume of children treated before the age of 12 months was statistically significantly smaller than those treated later. There was no difference between mean volume of fellow orbits in unilateral RB and controls. The mean orbital asymmetry index in control children (2.6%) was statistically significantly smaller than in RB survivors (14%). CONCLUSIONS There was a significant orbital growth retardation after enucleation and/or irradiation for RB. There was no difference between mean orbital volumes after enucleation, radiation or both. Orbital growth retardation was most prominent in children treated in the first year of life. Although small in number, our study suggests that deferring enucleation and/or irradiation until after the age of 12 months may reduce long-term complications.

Abstract
Chemotherapy has been used to treat a multitude of eye cancers. We attempted to review the role of chemotherapy in the treatment of ocular, adnexal, and orbital malignancies by conducting an extensive search of the medical literature. Unfortunately, the published reports typically contain few patients with limited follow-up, precluding definitive recommendations. For most eye cancers, multicenter trials will offer the potential to gather the numbers of patients required to determine the clinical utility of chemotherapy.

Abstract
PURPOSE To evaluate the efficacy of first-line chemotherapy (CT) in preventing external-beam radiotherapy (EBR) and/or enucleation in patients with retinoblastoma (Rbl). PATIENTS AND METHODS Twenty-four patients with newly diagnosed unilateral or bilateral Rbl received CT associated with local treatment (LT). Two to five courses of etoposide and carboplatin were administered at 3- to 4-week intervals, depending on tumor response, and were completed each time by LT. RESULTS Tumor response was observed in all eyes. Twenty-one of 24 patients showed a complete response (CR) that persisted at a median follow-up (FU) of 31 months (range, 4 to 41 months). Among the three patients who relapsed, two were lost to FU and one died of progressive disease. CR was achieved by CT and LT alone in 15 (71.4%) of 21 patients with less advanced disease (groups I to III). Six other patients with advanced disease (groups IV and V) experienced treatment failure and needed salvage treatment by EBR and/or enucleation. The difference between the two patient groups with regard to disease stage was statistically significant (P <.0001). EBR could be avoided in 13 (68.4%) of 19 patients, who presented with groups I to III (15 eyes) and group V (one eye) disease, whereas enucleation could be avoided in only two (40%) of five. CONCLUSION CT combined with intensive LT is effective in patients with groups I to III Rbl, permitting the avoidance of EBR in the majority of these young children and, thus, reducing the risk of long-term sequelae. This is in contrast with the disappointing results for patients with groups IV and V Rbl, in whom EBR and/or enucleation was needed.

Abstract
OBJECTIVE This study aimed to evaluate the causes of rhegmatogenous retinal detachment in children with retinoblastoma and to assess the surgical approach and results of retinal reattachment surgery. DESIGN The study design was a retrospective review of all children in whom a rhegmatogenous retinal detachment developed after treatment for retinoblastoma over a 20-year period. PARTICIPANTS Nine children, 5 to 33 months of age, participated. MAIN OUTCOME MEASURES Assessment of the treatment methods for retinoblastoma, apparent cause of the rhegmatogenous retinal detachment, interval from the most recent retinoblastoma treatment until repair of the rhegmatogenous retinal detachment, method of surgical repair, and long-term anatomic and visual results were measured. RESULTS Rhegmatogenous retinal detachment was diagnosed in nine eyes of nine children with treated retinoblastoma. Prior treatment of retinoblastoma included cryotherapy (n = 5), laser photocoagulation (n = 1), external beam radiation therapy (n = 7), and systemic chemotherapy (n = 4). An atrophic retinal hole was present at the most recent site of cryotherapy in three eyes and of laser photocoagulation in one eye. Extreme retinal thinning with a possible retinal break was noted in two eyes at a cryotherapy site. A dialysis was noted in one eye, and a retinal break could not be detected in two eyes. Treatment of retinoblastoma tumors was performed between 1 week and 15 years before retinal reattachment surgery. The retinal detachment was repaired externally with a scleral buckling procedure in seven eyes, with subretinal fluid drainage in five eyes, and without drainage in two eyes. Cytologic evaluation of subretinal fluid was performed in three eyes and showed no tumor cells. The retinal detachment was repaired by pars plana vitrectomy in one eye, and the vitrectomy specimen showed no tumor cells. In one child, the retinal detachment was not repaired. The retina remained attached after surgery in five eyes with follow-up ranging from 5 to 115 months. In three eyes, retinal redetachment associated with recurrent viable intraocular retinoblastoma was noted after surgery, necessitating enucleation. In no case was orbital or metastatic retinoblastoma detected at follow-up. CONCLUSIONS Rhegmatogenous retinal detachment in children with treated retinoblastoma generally originates from an atrophic retinal hole at the site of prior cryotherapy or laser photocoagulation. If there appears to be complete regression of the intraocular tumor after treatment, surgical repair of the rhegmatogenous retinal detachment may be approached cautiously.

Abstract
PURPOSE The principal objectives of this study were to estimate the incidence of second tumors among children treated for heritable retinoblastoma during a 50-year period and to investigate the relationship between these tumors and previous radiation therapy. METHODS The records of all retinoblastoma patients examined at the Mayo Clinic from 1941 through 1990 were retrospectively reviewed. The therapeutic modality used to manage the tumor, the occurrence of any second malignancy, and current follow-up on all patients were evaluated. RESULTS Eighty-two (46%) of 180 children with retinoblastoma had bilateral tumors (76 patients) or unilateral disease and a positive family history (six patients) and were followed for an average of 21.8 years (range, 1 month to 53 years). The Kaplan-Meier estimates of second nonocular tumors among the 82 patients with heritable retinoblastoma were 12% at 10 years, 16% at 25 years, and 30% at 40 years. Although 14 of the 15 patients who developed second malignancies had received radiation therapy, only four of the malignancies occurred within the field of irradiation. CONCLUSIONS The relatively low incidence of second tumors among long-term survivors of heritable retinoblastoma in this series of patients occurred predominantly outside the field of irradiation. The variable incidence of second nonocular malignancies in previous reports may reflect variations in radiation technique and dosage.

Abstract
BACKGROUND: Retinoblastoma is the most common intraocular malignancy of infants and children. With early diagnosis and treatment, survival is greater than 90%; however, patients with a germline retinoblastoma mutation have a substantial risk of having a second high-grade malignancy. METHODS: The recent developments in the diagnosis and treatment of retinoblastoma are reviewed. RESULTS: Identification of the retinoblastoma germline mutation is now possible with the discovery of the retinoblastoma gene. Patients with the germline mutation have a 51% cumulative risk over 50 years of developing a second malignancy. Several pilot studies using primary chemotherapy for retinoblastoma have shown promising results. CONCLUSIONS: Risk assessment and genetic counseling have become more precise with the development of laboratory methods to identify the retinoblastoma gene. The development of primary chemotherapy regimens to reduce the size of retinoblastoma tumors may decrease the need for radiation therapy and thereby reduce the risk of radiation-related malignancies in patients with the germline mutation.

Abstract
OBJECTIVE This study aimed to investigate the relationship in bilateral retinoblastoma survivors between the incidence of second tumors and the age when external beam radiation (EBR) was used. DESIGN A retrospective analysis of patients diagnosed with retinoblastoma was performed by examining records for background information and treatment information as well as reviewing documentation of patients with second nonocular tumors. Two telephone interviews were conducted for follow-up as well as inquiries directed to tumor registries and state databases. PARTICIPANTS The original study included 1729 patients treated in New York and Boston; the current study includes only the 1506 patients treated in New York. Of those, 816 patients were diagnosed with bilateral retinoblastoma, had sufficient treatment data to be useful, and survived at least 1 year from diagnosis. MAIN OUTCOME MEASURES The subjects were observed for evidence of the development of second nonocular tumors. RESULTS There was a significant decrease in tumor-free survival among patients treated with EBR before the age of 12 months, but no significant difference between the group treated with EBR after the age of 12 months and the group not treated with EBR. For tumors in the field of radiation, patients treated with early EBR showed a significant decrease in tumor-free survival when compared to patients treated with late EBR, with no significant difference between late radiation and no radiation. There were no significant differences between groups for tumors out of the field of radiation. Significant differences attributable to the use of EBR were found only for tumors of the skull and face bones and for tumors of the soft tissue of the head. CONCLUSIONS The long-term effect of radiation treatment on survivors of bilateral retinoblastoma is to increase the incidence and affect the distribution of second tumors. However, no increased risk is observed for tumors out of the field of radiation among patients who underwent radiation, and the risk for tumors in the field of radiation is heavily dependent on the age at which EBR is given and may be acceptably small to the patient after the age of 12 months.
