Abstract
BACKGROUND There is little information on the outcome of patients with retinoblastoma and tumor at the resection margin of the optic nerve. PROCEDURE Retrospective evaluation of three successive prospective protocols. Twenty-six consecutive patients were analyzed (International Staging System-IRSS-stage 2 = 21, stage 3 = 5) from three successive prospective protocols (1988-2006). Patients with stage 2 were enucleated upfront and those with stage 3 had neoadjuvant chemotherapy followed by enucleation and adjuvant therapy. Both groups received adjuvant chemotherapy and orbital radiotherapy after enucleation. Patients in protocol 1 received 1 year of the lower-dose chemotherapy regimen including cyclophosphamide, vincristine and doxorubicin along with intrathecal chemotherapy. Patients of protocols 2 and 3 received a more intense and shorter intravenous regimen including carboplatin and etoposide alternating with cyclophosphamide, idarubicin and vincristine with no intrathecal treatment. The components of protocol 2 and 3 were similar except for the dose of carboplatin which was 10% lower in protocol 3. RESULTS Thirteen were treated in protocol 1 and 13 in protocols 2 and 3. The probability of event-free survival was 0.70 at 5 years. Events included: CNS relapse = 3, second malignancies = 3, death in complete remission = 2. There were no significant differences in outcome between protocols or stages. Endocrinological disturbances related to the hypothalamus-hypophysis axis were evident in 6/8 patients evaluated. Severe orbital sequelae occurred in 12 cases. CONCLUSIONS A substantial number of patients with tumor at the resection margin of the optic nerve can be cured with current therapy; however, therapy related sequelae are frequent.

Abstract
The primary goal of phase II window studies in cancer is testing new single agents or combination therapies for newly diagnosed patients who are less likely to have multiple-drug-resistant tumours than the typical phase II patients who have failed one or more chemotherapeutic regimens. In addition, by utilizing newly diagnosed patients, one can assess the responsiveness in a population more representative of where the phase II agent might be applied in a true phase III setting. In general, the outcome of a patient on a phase II window study can be categorized as response, stable disease, or early disease progression. Phase II window studies sometimes require early stopping rules for both insufficient response rate and excessive early progression rates. In this paper, one-stage and two-stage designs for phase II window studies are developed, requiring the monitoring of two rates. It is shown that the power function is monotone in response rate and early disease progression rate. Consequently, the significance level and power are easy to compute. Computational procedures are described and examples are provided. The proposed method can be applied to other studies with categorical outcomes.

Abstract
Retinoblastoma is a rare eye tumor of childhood that arises in the retina. It is the most common intraocular malignancy of infancy and childhood; with an incidence of 1/15,000–20,000 live births. The two most frequent symptoms revealing retinoblastoma are leukocoria and strabismus. Iris rubeosis, hypopyon, hyphema, buphthalmia, orbital cellulites and exophthalmia may also be observed. Sixty per cent of retinoblastomas are unilateral and most of these forms are not hereditary (median age at diagnosis two years). Retinoblastoma is bilateral in 40% of cases (median age at diagnosis one year). All bilateral and multifocal unilateral forms are hereditary. Hereditary retinoblastoma constitutes a cancer predisposition syndrome: a subject constitutionally carrying an RB1 gene mutation has a greater than 90% risk of developing retinoblastoma but is also at increased risk of developing other types of cancers. Diagnosis is made by fundoscopy. Ultrasound, magnetic resonance imaging (MRI) and computed tomography (CT) scans may contribute to diagnosis. Management of patients with retinoblastoma must take into account the various aspects of the disease: the visual risk, the possibly hereditary nature of the disease, the life-threatening risk. Enucleation is still often necessary in unilateral disease; the decision for adjuvant treatment is taken according to the histological risk factors. Conservative treatment for at least one eye is possible in most of the bilateral cases. It includes laser alone or combined with chemotherapy, cryotherapy and brachytherapy. The indication for external beam radiotherapy should be restricted to large ocular tumors and diffuse vitreous seeding because of the risk of late effects, including secondary sarcoma. Vital prognosis, related to retinoblastoma alone, is now excellent in patients with unilateral or bilateral forms of retinoblastoma. Long term follow-up and early counseling regarding the risk of second primary tumors and transmission should be offered to retinoblastoma patients.

Abstract
PURPOSE The Soft Tissue Sarcoma Committee of the Children's Oncology Group has conducted five upfront window trials in patients with newly diagnosed metastatic rhabdomyosarcoma to identify promising new treatment agents. PATIENTS AND METHODS This pooled analysis identified a total of 420 patients (115 from Intergroup Rhabdomyosarcoma Study III [IRS-III] and 305 from the five window trials). We assessed window therapy response rate, failure-free survival (FFS), and overall survival (OS). RESULTS Response rates (complete + partial response) assessed at week 6 of window therapy ranged from 41% to 55% and did not predict FFS (P = .073) or OS (P = .31). FFS was influenced by trial (P = .048); patients enrolled onto IRS-III and the ifosfamide/etoposide and ifosfamide/doxorubicin trials fared best. When grouped and compared with topoisomerase I poison trials, ifosfamide/topoisomerase II inhibitor trials had superior FFS (P = .013). However, there was no difference in survival. CONCLUSION Upfront phase II window trials can efficiently provide robust estimates of activity for new agents and combinations in newly diagnosed patients with high-risk rhabdomyosarcoma. Our data indicate that, for some phase II window trials, the risk of treatment failure may be increased but that the trend towards lower survival for some of the window trials compared with IRS-III is not statistically significant. Window nonresponders did not suffer worse FFS or OS than patients who responded to window therapy. Finally, these results provide a rationale for incorporating ifosfamide, etoposide, doxorubicin, and topoisomerase I poisons in future trials of high-risk metastatic rhabdomyosarcoma.

Abstract
INTRODUCTION Retinoblastoma (RB) is the most frequent malignant eye tumor in childhood. In developing countries advanced stages are common. The purpose of this paper is to present our 21-year clinical experience with metastatic extra ocular RB patients treated with 5 different chemotherapy schemas at a single Mexican Pediatric referral center. MATERIALS AND METHODS A retrospective analysis was carried out reviewing the clinical characteristics of patients with metastatic RB. The information analyzed included the delay in diagnosis after first symptoms, age, sex, ocular staging, and anatomic site of metastases, treatment scheme, initial response and status at the last contact or date of death. RESULTS Eighty-one patients were included; age range was from 3 to 80 months. The most common site of metastasis was central nervous system (83.9%). From those patients treated with chemotherapy (n = 74), 89.2% presented a complete initial response (n = 66). Early mortality occurred in 7 cases before any treatment. Fifty-six received treatment and died with progressive disease. All patients without radiotherapy died with tumor activity (n = 15). The use of cisplatin was related with longer disease free intervals; no other variable was related with survival. Four patients were alive and disease free at 33 to 144.3 months of follow up from diagnosis. The prevalent cause of death was tumor progression. CONCLUSIONS In our experience, metastatic RB has a very high mortality rate in spite of the use of different chemotherapy regimens.

Abstract
AIMS To describe the outcome of patients with non-metastatic unilateral retinoblastoma with high risk histopathological features after primary enucleation, and to clarify the need and results of adjuvant therapy. PATIENTS AND METHODS From 1980 to 2001 adjuvant therapy was recommended only to patients with scleral involvement, post-laminar optic nerve involvement (PLONI) with either a positive margin or associated choroidal involvement, or (before 1994) isolated PLONI. RESULTS 108 of 224 patients had at least one high risk feature (choroidal, scleral, anterior chamber, and/or PLONI). Patients with isolated choroidal (n = 55) or anterior chamber (n = 2) invasion, and most with PLONI without other risk factors (n = 21) were not treated; three relapsed but are long term survivors after intensive therapy. Four with isolated PLONI received adjuvant chemotherapy and none relapsed. Three of 11 with PLONI and concomitant choroidal or scleral involvement who received adjuvant therapy relapsed, versus two of four not treated. Two of five with scleral disease relapsed. All 12 with cut end involvement received adjuvant treatment and none relapsed. In the total group, all four patients who relapsed after adjuvant therapy died. CONCLUSIONS Relapsing patients can be rescued with intensive therapy. Those with isolated choroidal or PLONI have a good prognosis without adjuvant therapy. Patients with PLONI with a positive margin have a good prognosis if treated with combined therapy. Those with scleral involvement or PLONI with concomitant choroid disease may benefit from adjuvant therapy.

Abstract
PURPOSE To report our experience with topotecan in children with relapsed/refractory metastatic and intraocular retinoblastoma. PATIENTS AND METHODS Topotecan was administered intravenously as a 30-min infusion at a dose of 2 mg/m2/d for five consecutive days and repeated after three weeks. If obvious progression was detected by physical examination in patients with overt extraocular disease or if progressive disease was noted after fundoscopic examination in patients with intraocular disease, a second cycle was not administered. Response was evaluated at Week 6. RESULTS Nine patients (6 extraocular, 3 intraocular) were treated from November 1998 to March 2002. A total of 16 cycles were administered. In patients with extraocular disease, there were three partial responses, two cases of stable disease, and one case of progressive disease. Two patients with relapsed/resistant intraocular disease had partial response. allowing local therapy to be performed, and the third patient had progressive disease. The drug was well-tolerated. No patient developed fever or documented infections. No other serious toxicity was found. CONCLUSION Topotecan is active in extraocular and relapsed/resistant intraocular retinoblastoma. The role of this drug in the treatment of retinoblastoma should be explored in further studies.

Abstract
BACKGROUND The objectives of this prospective study were to avoid adjuvant treatment for patients with intraocular disease and patients with postlaminar optic nerve invasion (PL-ONI) without full choroidal or scleral invasion. Adjuvant chemotherapy (Regimen 1) was given to patients with scleral invasion, PL-ONI without cut section, and full choroidal and/or scleral invasion. A more intensive regimen of higher dose intravenous chemotherapy (Regimen 2) and local radiotherapy was given to patients with PL-ONI and compromise at the cut end and to patients with overt extraocular disease. METHODS Six-month intravenous chemotherapy included carboplatin plus etoposide alternating with cyclophosphamide plus vincristine (Regimen 1) and the same drugs at higher dosage plus idarubicin (Regimen 2). Chemoreduction with carboplatin and vincristine with or without etoposide was given to selected patients (n = 39 patients). RESULTS From 1994 to 2001, 169 patients were evaluable at the Hospital Garrahan (Buenos Aires, Argentina). One hundred eighteen patients with intraocular disease had a 5-year disease free survival (DFS) rate of 0.98, including 54 patients with choroidal invasion. None of 22 patients with isolated PL-ONI developed recurrent disease, whereas 2 of 8 patients with concomitant risk factors had tumor recurrences and died. Three of 5 patients with scleral invasion survived, and 7 of 10 patients with cut-end ONI survived. The only patient with metastatic disease that survived (n = 6) had only lymph node invasion. CONCLUSIONS Adjuvant therapy can be avoided in patients with intraocular and isolated PL-ONI. Patients with PL-ONI who also had other risk factors required intensive adjuvant therapy, such as patients with cut-end and overt extraocular disease. Metastatic disease was not found to be curable with this approach.

Abstract
BACKGROUND Overt extraocular retinoblastoma is common in developing countries and little information about its treatment is available. The aim of this study is to report our experience in the treatment of these cases using a uniform approach. PROCEDURE Patients with overt extraocular retinoblastoma including orbital extension, preauricular lymph node invasion and/or metastatic disease on diagnosis or after extraocular relapse admitted to the Hospital JP Garrahan from August 1987 to December 2000 were retrospectively reviewed. Patients were treated according to two different protocols (1987-1993 and 1994-2000). Treatment included: neoadjuvant combination chemotherapy followed by limited surgery in case of orbital extension (enucleation or resection of residual orbital mass) and adjuvant chemotherapy and radiotherapy. Chemotherapy included cyclophosphamide, vincristine, etoposide, doxorubicin (in protocol 87), idarubicin (in protocol 94), cisplatin (in protocol 87), and carboplatin (in protocol 94). RESULTS Forty-one patients were included. Fifteen of them had orbital or preauricular disease and had a 5-year event-free survival (pEFS) of 84%. Twenty-six had distant metastatic disease and non survived 5-years. One patient died of toxicity and one died in complete remission. One patient had a secondary leukemia. The remaining adverse events included CNS and/or systemic relapse. CONCLUSIONS This treatment strategy was highly efficacious for patients with orbital and/or lymph node extension. Orbital exenteration is not necessary for these patients. Those patients with distant metastatic or CNS disease were not curable with this approach.
