[PMID: 34688803 DOI: 10.1016/j.jep.2021.114770] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/31/2021] [Revised: 10/11/2021] [Accepted: 10/19/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The bulb of Eleutherine bulbosa (Mill.) Urb. is an indigenous medicinal plant traditionally used among Dayak people for the management of diabetes, breast cancer, hypertension, stroke, and fertility problems in women. The bulb has been reported with a potent cytotoxic potential but with limited underlying mechanisms. AIM OF THE STUDY This study aimed to investigate the cytotoxic properties of E. bulbosa ethanolic bulb extracted under optimised extraction condition on retinoblastoma cancer cells (WERI-Rb-1) through in vitro cell culture bioassays. The optimised extraction condition has been determined in the previous reports. MATERIALS AND METHODS Cytotoxic assay was analysed through MTT assay. Comparison between non-optimised and optimised extraction condition from E. bulbosa ethanolic bulb extract was evaluated. Morphological assessment of apoptotic cells was conducted through acridine orange propidium iodide (AOPI) staining using fluorescence microscopy. Apoptosis assay was carried out through Annexin V-FITC and cell cycle analysis through PI staining. The effect of varying concentrations (IC25, IC50, IC75) of the optimised E. bulbosa ethanolic bulb extract was observed. The mRNA expression was also conducted to confirm the underlying mechanism. RESULTS The optimised E. bulbosa ethanolic bulb extract markedly suppressed the proliferation of retinoblastoma cancer cells significantly with an IC50 value of 15.7 μg/mL as compared to non-optimised extract (p < 0.01). Fluorescence microscopy revealed that retinoblastoma cancer cells manifested early features of apoptosis-like membrane blebbing, chromatin condensation and formation of apoptotic bodies in a dose-dependent manner. The number of apoptotic cells were greatly observed in early and late apoptosis through Annexin V-FITC and the extract also induced cell arrestment as compared to the untreated group. The apoptosis was confirmed with the upregulation of Bax, Bad, p53, Caspase 3, Caspase 8, and Caspase 9 genes meanwhile, Bcl-2, BcL-xL, Nrf-2, and HO-1 genes were downregulated. CONCLUSION The optimised E. bulbosa ethanolic bulb extract induced a significant cell death and cell cycle arrestment on retinoblastoma cancer cells. It could be suggested that the induction of apoptosis in retinoblastoma cancer cells may be due to the synergistic effect of the bioactive compounds extracted under optimised extraction condition. Our findings indicated that E. bulbosa bulb could be promising chemotherapeutic potential to treat retinoblastoma cancer cells.

Abstract
BACKGROUND Retinoblastoma (RB) outcomes in Thailand are unfavorable compared to those of developed countries. This study aims to determine whether the clinical outcomes of patients with RB significantly improved after the implementation of new therapeutic approaches and which clinical factors affect survival and globe-saving outcomes. METHODS The medical records of patients newly diagnosed with RB and treated at Siriraj Hospital between January 2005 and December 2018 were reviewed retrospectively. Clinical data, treatments, and outcomes were collected and analyzed. RESULTS In 194 eyes (144 patients), leukocoria was the most common presenting feature (76.8%); 129 (66.5%) eyes were staged in group E of the International Classification of Intraocular Retinoblastoma. Of the 149 enucleated eyes, 35 had high-risk histopathological features, mostly choroidal invasion; 45 eyes (23.2%) could be salvaged. The 5-year overall survival rate was 90.3%, an improvement compared to the previous study. The 5-year enucleation-free survival rates of Groups A and B, C, D and E were 100%, 83.1%, 36.7% and 16.6% respectively. Factors associated with a lower survival rate were interval from symptom onset to diagnosis >3 months (hazard ratio (HR): 5.8: 95% confidence interval (CI): 1.637, 20.579) and buphthalmos (HR: 12.57: 95% CI: 3.936, 40.153). Factors associated with high-risk features were secondary glaucoma (HR: 11.016: 95% CI: 1.24, 98.10) and pseudohypopyon (HR: 14.110: 95% CI: 2.16, 92.05). CONCLUSIONS Survival rates and globe-saving rates appear to have improved; however, advanced-stage presentation remains the major hindrance. Further studies with a larger cohort and longer follow-up are warranted.

Abstract
Retinoblastoma is the most common ocular malignancy of childhood. With an estimated 300 cases annually in the United States, retinoblastoma is nevertheless considered a rare tumor. Although retinoblastoma primarily affects younger children, diagnosis during the neonatal age range is less common. However, an understanding of patients at risk is critical for appropriate screening. Early detection and treatment by a multidisciplinary specialty team maximizes the chance for survival and ocular/vision salvage while minimizing treatment-related toxicity. Testing for alterations in the RB1 gene has become standard practice, and informs screening and genetic counseling recommendations for patients and their families.

MiR-486-3p inhibits the proliferation, migration and invasion of retinoblastoma cells by targeting ECM1. Biosci Rep 2020; 40:224127. [PMID: 32401301 PMCID: PMC7273916 DOI: 10.1042/bsr20200392] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2020] [Revised: 05/06/2020] [Accepted: 05/12/2020] [Indexed: 11/19/2022] Open
Abstract
It has been reported that miR-486-3p expression is decreased in retinoblastoma (RB) tumor tissues, however, its function in RB has been less reported. The present study aimed to explore the regulatory effects of miR-486-3p on RB cells. The expression of miR-486-3p in RB tissues and cells was detected by quantitative real-time polymerase chain reaction (qRT-PCR). Cell viability, proliferation, apoptosis, migration and invasion ability were determined by cell counting kit-8 (CCK-8) kit, clone formation assay, flow cytometry, scratch assay and transwell, respectively. Targetscan 7.2 and dual-luciferase reporter were used to verify target genes for miR-486-3p. The expressions of apoptosis-related proteins and ECM1 were detected by Western blot. The miR-486-3p expression was decreased in RB tissues and cells. In RB cells, overexpression of miR-486-3p inhibited cell proliferation, migration and invasion, while promoted apoptosis. Moreover, overexpression of miR-486-3p decreased Bcl-2 expression, while increased the expressions of Bax and Cleaved Caspase-3 (C caspase-3). ECM1 was the target gene of miR-486-3p, and miR-486-3p inhibited the expression of ECM1. Furthermore, ECM1 partially reversed the inhibitory effect of miR-486-3p on the proliferation, migration and invasion of RB cells. MiR-486-3p inhibited the proliferation, migration and invasion of RB by down-regulating ECM1.

Abstract
BACKGROUND Retinoblastoma with macroscopic optic nerve (ON) invasion depicted by imaging at diagnosis remains a major problem and carries a poor prognosis. We sought to describe the treatment and outcome of these high-risk patients. METHODS Retrospective mono-institutional clinical, radiological, and histological review of patients with uni- or bilateral retinoblastoma with obvious ON invasion, defined by radiological optic nerve enlargement (RONE) depicted by computed tomography scan or magnetic resonance imaging (MRI), was performed. RESULTS Between 1997 and 2014, among the 936 patients with retinoblastoma treated at Institut Curie, 11 had detectable RONE. Retinoblastoma was unilateral in 10 and bilateral in one. Median age at diagnosis was 28 months (range, 11-96). ON enlargement extended to the orbital portion in three patients, to the optic canal in five, to the prechiasmatic portion in two, and to the optic chiasm in one. Nine patients received neoadjuvant chemotherapy and partial response was obtained in all. Enucleation was performed in 10/11 patients-by an anterior approach in three and by anterior and subfrontal approaches in seven. Three patients had a positive ON resection margin (2/3 after primary enucleation). All enucleated patients received adjuvant treatment (conventional chemotherapy: 10, high-dose chemotherapy: seven, radiotherapy: five). Leptomeningeal progression occurred in four patients. Seven are in first complete remission (median follow up: 8 years [3.5-19.4]). CONCLUSION Neoadjuvant chemotherapy and microscopic complete resection have a pivotal role in the management of retinoblastoma with RONE. MRI is recommended for initial and pre-operative accurate staging. Surgery should be performed by neurosurgeons in case of posterior nerve invasion. Radiotherapy is required in case of incomplete resection.

Abstract
BACKGROUND Chimeric antigen receptor (CAR)-based T cell therapy is in early clinical trials to target the neuroectodermal tumor, neuroblastoma. No preclinical or clinical efficacy data are available for retinoblastoma to date. Whereas unilateral intraocular retinoblastoma is cured by enucleation of the eye, infiltration of the optic nerve indicates potential diffuse scattering and tumor spread leading to a major therapeutic challenge. CAR-T cell therapy could improve the currently limited therapeutic strategies for metastasized retinoblastoma by simultaneously killing both primary tumor and metastasizing malignant cells and by reducing chemotherapy-related late effects. METHODS CD171 and GD2 expression was flow cytometrically analyzed in 11 retinoblastoma cell lines. CD171 expression and T cell infiltration (CD3+) was immunohistochemically assessed in retrospectively collected primary retinoblastomas. The efficacy of CAR-T cells targeting the CD171 and GD2 tumor-associated antigens was preclinically tested against three antigen-expressing retinoblastoma cell lines. CAR-T cell activation and exhaustion were assessed by cytokine release assays and flow cytometric detection of cell surface markers, and killing ability was assessed in cytotoxic assays. CAR constructs harboring different extracellular spacer lengths (short/long) and intracellular co-stimulatory domains (CD28/4-1BB) were compared to select the most potent constructs. RESULTS All retinoblastoma cell lines investigated expressed CD171 and GD2. CD171 was expressed in 15/30 primary retinoblastomas. Retinoblastoma cell encounter strongly activated both CD171-specific and GD2-specific CAR-T cells. Targeting either CD171 or GD2 effectively killed all retinoblastoma cell lines examined. Similar activation and killing ability for either target was achieved by all CAR constructs irrespective of the length of the extracellular spacers and the co-stimulatory domain. Cell lines differentially lost tumor antigen expression upon CAR-T cell encounter, with CD171 being completely lost by all tested cell lines and GD2 further down-regulated in cell lines expressing low GD2 levels before CAR-T cell challenge. Alternating the CAR-T cell target in sequential challenges enhanced retinoblastoma cell killing. CONCLUSION Both CD171 and GD2 are effective targets on human retinoblastoma cell lines, and CAR-T cell therapy is highly effective against retinoblastoma in vitro. Targeting of two different antigens by sequential CAR-T cell applications enhanced tumor cell killing and preempted tumor antigen loss in preclinical testing.

Abstract
Background Retinoblastoma (Rb) is the most common intraocular tumor diagnosed in children in Brazil. However, detailed information is lacking regarding patient clinical demographics. This study aimed to determine the clinical profile of patients with Rb who were treated in a public university hospital in southern Brazil from 1983 to 2012. Methods: Patients’ medical records were reviewed to retrospectively identify patients with a principal diagnosis of Rb. Rb was classified as hereditary or non-hereditary. Clinical staging was reviewed by an ophthalmologist. Statistical analysis was performed using SPSS. Results Of 165 patients with a diagnosis of Rb during this period, 140 were included in the study. Disease was unilateral in 65.0 % of patients, bilateral in 32.9 %, and trilateral in 2.1 %. The mean age at onset of the first sign/symptom was 18.1 month, and 35.7 % of patients were diagnosed during the first year of life. The most common presenting signs were leukocoria (73.6 %) and strabismus (20.7 %). The mean age at diagnosis was 23.5 months, and time to diagnosis was 5.4 months. In patients with clinical features of hereditary Rb, both onset of the first sign/symptom and diagnosis were at an earlier age than in patients without these features (12.3 vs 21.6 months [P = 0.001] and 15.9 vs 28.0 months [P < 0.001], respectively). However, there was no significant difference in overall survival between the two groups. Ocular stage at diagnosis was advanced in 76.5 % (Reese V) and 78.1 % (International Classification D or E). Of patients with unilateral and bilateral disease, 35.2 % and 34.8 %, respectively, had extraocular disease at diagnosis; 10.7 % had metastatic disease at diagnosis. Enucleation was observed in 88.1 % and exenteration in 11.9 % of patients; 93.6 % patients were followed until 2012, and 22.9 % relapsed. Overall survival was 86.4 %. Conclusions Most Rb diagnoses are still diagnosed in advanced stages of the disease, considerably reducing overall survival time and the rate of eye and vision preservation.

Abstract
In the developed world, retinoblastoma is an uncommon yet highly curable ocular malignancy of childhood affecting 40-50 children in the UK each year. The presenting signs, most commonly leukocoria and squint, should alert the primary care physician or secondary care physician to examine for the red reflex, the absence of which is an indication for urgent ophthalmology assessment. Diagnosis is made by clinical examination and staging may include bone marrow sampling, lumbar puncture and MRI scanning. CT should be avoided to reduce radiation exposure in a population of whom a proportion are at considerable risk of second malignancies. Although enucleation is necessary for many children, over recent years there has been a growing emphasis on conservative management in an attempt to reduce the need for enucleation and avoid the adverse late effects associated with external beam radiotherapy. This review will describe approaches to treatment in the UK and how the stage, laterality and position of the tumour within the eye influence treatment choices.

Abstract
While advances in the treatment of pediatric cancers have increased cure rates, children with metastatic or recurrent solid tumors have a dismal prognosis despite initial transient responses to therapy. Autologous hematopoietic stem cell transplantation takes advantage of the steep dose-response relationship observed with many chemotherapeutic agents. While clearly demonstrated to improve outcomes in patients with metastatic neuroblastoma, autologous hematopoietic stem cell transplantation is also frequently used to treat patients with other high-risk diseases such as Ewing sarcoma, osteosarcoma, rhabdomyosarcoma, Wilms' tumor, retinoblastoma, germ cell tumors, lymphomas and brain tumors. Most published experience consists of retrospective, single-arm studies; randomized clinical trials are lacking, due in part to the rarity of pediatric cancers treatable by autologous hematopoietic stem cell transplantation. These published literature demonstrate that autologous hematopoietic stem cell transplantation results in most cases in equivalent or superior outcomes when compared with conventional therapies. However, patient heterogeneity, patient selection, graft characteristics and processing and the varied conditioning regimens are additional factors to consider. Since the inception of autologous hematopoietic stem cell transplantation, regimen-related toxicity has markedly decreased and the vast majority of treatment failures are now due to disease recurrence. Prospective clinical trials are needed to identify specific high-risk patient populations, with randomization (when possible) to compare outcomes of patients undergoing autologous hematopoietic stem cell transplantation with those receiving standard therapy. In addition, investigators need to better define the role of autologous hematopoietic stem cell transplantation in these solid tumors, particularly in combination with other therapeutic modalities such as immunotherapy and novel cell processing methodologies.

Abstract
Children with solid tumors, most of which are malignant, have an excellent prognosis when treated on contemporary regimens. These regimens, which incorporate chemotherapeutic agents and treatment modalities used for many decades, have evolved to improve relapse-free survival and reduce long-term toxicity. This review discusses the evolution of the treatment regimens employed for management of the most common solid tumors, emphasizing the similarities between contemporary and historical regimens. These similarities allow the use of historical patient cohorts to identify the late effects of successful therapy and to evaluate remedial interventions for these adverse effects.

Abstract
Retinoblastoma remains incurable in many regions of the world. The major obstacles to cure are delayed diagnosis, poor treatment compliance, and lack of evidence-based recommendations for clinical management. Although enucleation is curative for intraocular disease, in developing countries retinoblastoma is often diagnosed after the disease has disseminated beyond the eye. A SIOP-PODC committee generated guidelines for the clinical management of retinoblastoma in developing countries and developed a classification system based on the resources available in those settings. Recommendations are provided for staging and treatment of unilateral and bilateral retinoblastoma and counseling of families for whom compliance is an issue.

Abstract
BACKGROUND Data on long-term outcomes of survivors of extra-ocular retinoblastoma are lacking. The authors sought to provide the first report characterizing long-term outcomes among survivors of extra-ocular retinoblastoma. PROCEDURE Retrospective analysis of long-term medical outcomes in 19 survivors of extra-ocular retinoblastoma treated between 1992 and 2009. Severity of outcomes was graded using Common Terminology Criteria for Adverse Events. All patients received intensive multimodality therapy for their extra-ocular disease after management of their primary intra-ocular disease, including conventional chemotherapy (n = 19, 100%), radiotherapy (n = 15, 69%), and/or high-dose chemotherapy with autologous stem cell transplant (n = 17, 89%). RESULTS The median follow-up was 7.8 years from diagnosis of extra-ocular retinoblastoma (range 2-17.8 years). The most common long-term non-visual outcomes were hearing loss (n = 15, 79%), short stature (n = 7, 37%), and secondary malignancies [SMN] (n = 6, 31%). Sixty-eight percent of survivors exhibited ≥2 non-visual long-term outcomes of any grade. Except short stature, which was not graded for severity, Grade 3-4 outcomes were limited to: ototoxicity (n = 8; n = 4 require hearing aids), SMNs (n = 6), and unequal limb length (n = 1). Five patients who developed SMNs carried a known RB1 mutation. SMNs developed at a median of 11.1 years after initial diagnosis; two patients died of their SMN. Long-term cardiac, pulmonary, hepatobiliary, or renal conditions were not identified in any survivors. CONCLUSION Long-term outcomes are commonly seen in extra-ocular retinoblastoma survivors but the majority are mild-moderate in their severity. Longer comprehensive follow-up is needed to fully assess treatment-related outcomes but the information collected to date may affect management decisions for children with extra-ocular disease.

Abstract
Retinoblastoma is an aggressive eye cancer of infancy and childhood. Survival and the chance of saving vision depend on severity of disease at presentation. Retinoblastoma was the first tumour to draw attention to the genetic aetiology of cancer. Despite good understanding of its aetiology, mortality from retinoblastoma is about 70% in countries of low and middle income, where most affected children live. Poor public and medical awareness, and an absence of rigorous clinical trials to assess innovative treatments impede progress. Worldwide, most of the estimated 9000 newly diagnosed patients every year will die. However, global digital communications present opportunities to optimise standards of care for children and families affected by this rare and often devastating cancer. Parents are now leading the effort for widespread awareness of the danger of leucocoria. Genome-level technologies could make genetic testing a reality for every family affected by retinoblastoma. Best-practice guidelines, online sharing of pathological images, point-of-care data entry, multidisciplinary research, and clinical trials can reduce mortality. Most importantly, active participation of survivors and families will ensure that the whole wellbeing of the child is prioritised in any treatment plan.

Abstract
Survival of retinoblastoma is >90% in developed countries but there are significant differences with developing countries in stage at presentation, available treatment options, family compliance, and survival. In low-income countries (LICs), children present with advanced disease, and the reasons are socioeconomic and cultural. In middle-income countries (MICs), survival rates are better (>70%), but there is a high prevalence of microscopically disseminated extraocular disease. Programs for eye preservation have been developed, but toxicity-related mortality is higher. Although effective treatment of microscopically extraocular disease improved the outcome, worldwide survival will be increased only by earlier diagnosis and better treatment adherence.

Abstract
Purpose Initial response of intraocular retinoblastoma to chemotherapy has encouraged primary chemotherapy instead of primary enucleation for eyes with clinical features suggesting high risk of extraocular extension or metastasis. Upfront enucleation of such high-risk eyes allows pathologic evaluation of extraocular extension, key to management with appropriate surveillance and adjuvant therapy. Does chemotherapy before enucleation mask histologic features of extraocular extension, potentially endangering the child's life by subsequent undertreatment? Methods We performed retrospective analysis of 100 eyes with advanced retinoblastoma enucleated with, or without, primary chemotherapy, in Beijing Tongren Hospital, retrospectively, from October 31, 2008. The extent of retinoblastoma invasion into optic nerve, uvea, and anterior chamber on histopathology was staged by pTNM classification. The treatment groups were compared for pathologic stage (Cochran-Armitage trend test) and disease-specific mortality (competing risks methods). Results Children who received chemotherapy before enucleation had lower pTNM stage than primarily enucleated children (P = .01). Five patients who received pre-enucleation chemotherapy died as a result of extension into brain or metastasis. No patients who had primary enucleation died. For children with group E eyes, disease-specific survival (DSS) was lower with pre-enucleation chemotherapy (n = 45) than with primary enucleation (n = 37; P = .01). Enucleation longer than 3 months after diagnosis was also associated with lower DSS (P < .001). Conclusion Chemotherapy before enucleation of group E eyes with advanced retinoblastoma downstaged pathologic evidence of extraocular extension, and increased the risk of metastatic death from reduced surveillance and inappropriate management of high-risk disease, if enucleation was performed longer than 3 months after diagnosis.

Abstract
Trilateral retinoblastoma is characterized by the presence of retinoblastoma with an intracranial tumor. The incidence is low and prognosis poor. Due to the paucity of information regarding successful treatment, we report the case of a 6 month old female referred for leukocoria and found to have an associated suprasellar tumor and pineal enhancement. The patient, treated with standard infant brain tumor therapy, remains alive without signs of active disease 35 months after diagnosis; no surgery or irradiation was used. Early diagnosis of trilateral retinoblastoma may facilitate the use of less intensive therapeutic approaches and result in excellent outcomes in these patients.

Abstract
BACKGROUND Few prospective studies about the management of unilateral retinoblastoma with pathology risk factors (PRFs) have been published. METHODS Patients (n = 114) were divided into four groups: Group 1 (initial chemoreduction) (n = 17). Groups 2 and 3, included patients initially enucleated with no, or lower risk PRFs: (n = 65) and with higher risk PRFs (n = 30), respectively. The later included postlaminar optic nerve involvement (PLONI) (n = 23), tumor at resection margin of optic nerve (n = 5) or isolated scleral invasion (n = 2). Group 3 received adjuvant chemotherapy including a total eight cycles of carboplatin and etoposide, alternating with cyclophosphamide, idarubicin, and vincristine. Orbital radiotherapy (45 Gy) was given to patients with invasion to the resection margin. Group 4 included patients with metastatic disease (n = 2). They were given neoadjuvant therapy followed by surgery and high-dose chemotherapy and autologous stem cell rescue. RESULTS Five-year event-free survival is 0.94 (1 for Group 1, 0.94 for Group 2, 0.96 for Group 3, and 0 for Group 4). Events included. Group 2: Systemic relapse (n = 2) and combined orbital and CNS relapse (n = 1). Relapsing patients had PLONI (n = 2) and isolated focal choroidal invasion (n = 1). Group 3: CNS relapse (n = 1) in a patient with tumor at the resection margin of optic nerve. Group 4: CNS relapse (n = 2). Only one relapsed patient survived. Eight of 17 eyes treated conservatively were preserved. CONCLUSIONS The survival of patients with unilateral retinoblastoma was excellent and 60% were spared from adjuvant treatment. Our intensive regimen was likely to be effective for prevention of metastasis in patients with higher risk PRFs.

Abstract
BACKGROUND Stage 4b retinoblastoma (central nervous system metastatic disease) has been lethal in virtually all cases reported. Here we describe a series of eight patients treated with intensive chemotherapy, defined as the intention to include high-dose chemotherapy with autologous hematopoietic stem cell rescue. PROCEDURE Induction chemotherapy included cyclophosphamide and/or carboplatin with a topoisomerase inhibitor. High-dose chemotherapy regimens were carboplatin and thiotepa with or without etoposide (n = 3) or carboplatin, etoposide, and cyclophosphamide (n = 2). RESULTS Seven patients had leptomeningeal disease and one patient had only direct extension to the CNS via the optic nerve. Three patients had stage 4b disease at the time of original diagnosis of the intra-ocular retinoblastoma; five had later onset at a median of 12 months (range 3-69 months). One patient died of toxicity (septicemia and multi-organ system failure) during induction and two had disease progression prior to high-dose chemotherapy. Five patients received high-dose chemotherapy at a median of 6 months (range 4-6) post-diagnosis of stage 4b disease. Two patients survive event-free at 40 and 101 months; one was irradiated following recovery from the high-dose chemotherapy. CONCLUSIONS Intensive multimodality therapy may be beneficial for some patients with stage 4b retinoblastoma. Longer follow-up will determine whether it has been curative.

Abstract
BACKGROUND We previously reported promising pilot results treating patients with stage 4a metastatic retinoblastoma with combined intensive conventional chemotherapy, high-dose chemotherapy with autologous hematopoietic stem cell rescue, and radiation therapy and now present an expanded and updated series. PROCEDURE Fifteen patients with bone marrow (n = 14), bone (n = 10), orbit (n = 9), and/or liver (n = 4) disease were treated. Induction chemotherapy usually consisted of vincristine, cyclophosphamide, cisplatin, and etoposide. The high-dose chemotherapy regimen included carboplatin and thiotepa alone (n = 1) or with etoposide (n = 5) or topotecan (n = 7). RESULTS Bone marrow cleared at first post-initiation of chemotherapy examination in all patients and stem cells were harvested after a median of 3.5 cycles of chemotherapy (range 3-6 cycles). Two patients progressed prior to high-dose chemotherapy and died. Thirteen received high-dose chemotherapy at a median of 6 months post-diagnosis of metastases (range 4-8 months). Ten are retinoblastoma-free in first remission at a median follow-up of 103 months (range 34-202 months) while three recurred (two in the CNS, one in the mandible) 14-20 months post-diagnosis of metastases. Retinoblastoma-free and event-free survival at 5 years are 67% (95% confidence interval 38-85%) and 59% (95% confidence interval 31-79%). Six of the 10 survivors received radiation therapy. Three patients developed secondary osteosarcoma 14, 4, and 9 years after diagnosis of metastatic disease. CONCLUSIONS Intensive multimodality therapy including high-dose chemotherapy with autologous hematopoietic stem cell rescue was curative for the majority of patients with stage 4a metastatic retinoblastoma treated. The contribution of external beam radiation therapy is unclear.

Abstract
BACKGROUND Trilateral retinoblastoma has been lethal in virtually all cases previously reported. We describe a series of 13 patients treated with intensive chemotherapy, defined as the intention to include high-dose chemotherapy with autologous hematopoietic stem cell rescue. PROCEDURE Induction chemotherapy generally included vincristine, cisplatin or carboplatin, cyclophosphamide, and etoposide. Hematopoietic stem cells typically were harvested after the first or second cycle of induction chemotherapy, usually from peripheral blood. High-dose chemotherapy regimens were thiotepa-based (n = 7) or melphalan and cyclophosphamide (n = 3). RESULTS Trilateral sites were pineal (n = 11) and suprasellar (n = 2); 7 patients had localized (M-0) disease and six had leptomeningeal dissemination (M-1+). Five patients had trilateral retinoblastoma at original diagnosis of intra-ocular retinoblastoma; eight later developed trilateral disease at a median of 35 months (range 3-60 months) following diagnosis of intra-ocular retinoblastoma. One patient died of toxicity (septicemia and multi-organ system failure) during induction and three developed disease progression prior to high-dose chemotherapy. Nine patients received high-dose chemotherapy at a median of 5 months (range 4-9) post-diagnosis of trilateral disease. Five patients survive event-free at a median of 77 months (range 36-104 months) and never received external beam radiation therapy. Four of seven patients with M-0 disease survive event-free versus only one of six patients with M-1+ disease. CONCLUSIONS Intensive chemotherapy is potentially curative for some patients with trilateral retinoblastoma, especially those with M-0 disease.

Abstract
OBJECTIVE Cerebrospinal fluid (CSF) metastasis is the most difficult type of retinoblastoma metastasis to cure, even with bone marrow transplant. Most metastatic retinoblastoma cells express P-glycoprotein causing multidrug resistance (MDR). P-glycoprotein-rich blood vessels form blood-brain and blood-eye barriers, inhibit drug entry into central nervous system (CNS) and eyes. High-dose craniospinal radiation is too morbid for treatment of young children. To cure CSF metastasis without radiation, we designed an intensive multimodality chemotherapy regimen. METHOD After left eye enucleation, a 4-month-old boy with bilateral International Intraocular Retinoblastoma Classification Group E eyes and CSF metastasis was treated with 7-cycle high-dose carboplatin and etoposide, standard-dose vincristine, and high-dose/short-infusion cyclosporine to inhibit P-glycoprotein. Intraventricular drugs, non-substrate of P-glycoprotein (cytarabine), or less susceptible to MDR (topotecan), contributed to treatment of the metastasis. On achieving complete response, he was consolidated with supralethal-dosage carboplatin, etoposide, and cyclophosphamide, and his bone marrow rescued with autologous cord blood stem cells. RESULTS Following 1-cycle systemic chemotherapy and 2-dose intraventricular chemotherapy, the CSF metastasis cleared. The right eye tumor regressed completely. The patient remains in remission 8.3 years after diagnosis and 7.8 years post-transplant. CONCLUSION Intensive multimodality chemotherapy can cure CSF metastasis in retinoblastoma without incurring extreme morbidity from craniospinal radiation.

Abstract
Introduction: Retinoblastoma is a very rare disease. There were 30 cases of retinoblastoma diagnosed and treated at National University Hospital (NUH).
Materials and Methods: A retrospective chart review was performed on the medical records of 30 patients who were diagnosed with retinoblastoma between 1995 and 2008 at the Department of Paediatrics, National University Hospital, Singapore.
Results: The median age at diagnosis was 1.6 years (range, 0-5.9) with a median follow-up of 1.8 years (range, 0.1 to 11.6). The median time from presenting signs to the time of diagnosis was 5.2 months (range, 0-25.2). Common presenting signs of retinoblastoma were identified; the most common of which were leukocoria (50.0%), squinting (13.3%), poor vision (10.0%), strabismus (6.6%) and unknown (33.3%). Of the 30 patients, 10 were from Singapore whilst the other 20 patients were from the surrounding countries. Twelve patients had bilateral disease at the time of diagnosis, while 18 had unilateral disease. Staging information was available in 27 patients. Enucleation was performed in 25 of 30 patients. Radiation therapy was given in 3 patients in 1995 (bilateral disease), 2001 (bilateral disease) and 2003 (unilateral disease). At the time of analysis, 19 patients were alive with no evidence of disease. Overall 5-year survival for the cohort was 88.1% [95% confidence interval (CI), 88.0-100] and event-free survival for the whole cohort was 74.2% (95% CI, 55.8-92.6).
Conclusion: In our limited experience, the importance of collaboration and standardisation of the staging system, raising awareness and education of primary healthcare providers and parents are strongly stressed.

Abstract
PURPOSE To provide an overview of the current clinical management of retinoblastoma by discussing the trends in the categorization, treatment, and recent advances in molecular diagnostics as well as therapy for retinoblastoma. DESIGN Literature review and commentary. METHODS Selected articles from the medical literature and the authors' clinical and research experience were reviewed critically. RESULTS Retinoblastoma has evolved from a deadly childhood cancer to a largely curable cancer within the past 40 years. Current treatment strategies aim to salvage the eye and provide the best visual outcome possible. Using the international classification system to stratify intraocular retinoblastoma into treatment groups, the multicenter Children's Oncology Group treatment protocols use 2- to 3-drug chemoreduction with focal consolidative therapy for most categories of disease. Furthermore, collaborative efforts are being directed toward a better understanding of genotype-phenotype relationships in retinoblastoma that will be useful in the multidisciplinary management of this disease. Molecular targeting therapy is emerging as a potential strategy to individualize therapy. Finally, improvements in local drug delivery methods and vehicles are providing solutions for the problem of systemic toxicity from existing chemotherapy regimens. CONCLUSIONS The management of retinoblastoma has become a prototype for other ophthalmic diseases and systemic cancers in which genetic information and molecular targets are being used to design more elegant treatment strategies.

Abstract
PURPOSE To provide an overview of the current literature surrounding the detection and management of retinoblastoma as well as care for the long-term survivor to serve as a guide for advanced practice nurses. DATA SOURCES Comprehensive review of the literature on retinoblastoma including case studies, journal reviews, retrospective studies, and briefs. CONCLUSIONS Retinoblastoma is a pediatric intraocular malignancy usually detected in the primary care setting. Typically asymptomatic, primary care providers will often identify the presence of retinoblastoma upon routine eye exam. Prompt diagnosis and commencement of treatment are paramount as delay in diagnosis leads to higher morbidity and mortality. Treatment options vary depending on the extent of disease. IMPLICATIONS FOR PRACTICE Although current survival rates for retinoblastoma exceed 90%, individual visual outcome and survival are dependent upon early detection and prompt referral. In addition to research and education of survivors and families, advanced practice nurses play a key role in early detection and maintaining the current survival rate.

Abstract
Treatment of retinoblastoma must be individualized. Most patients with unilateral, non-metastatic retinoblastoma can be cured with enucleation alone. In patients with histologic risk factors, adjuvant chemotherapy is recommended, with the addition of orbital radiation for patients with trans-scleral involvement or tumor present at the level of the cut end of the optic nerve. Patients with metastases require intensive chemotherapy and consolidation with autologous hematopoietic stem cell rescue. Patients with bilateral or multifocal disease represent a major challenge. Cure of the disease is the first priority, but the therapeutic approach also has to consider eye and vision preservation. The approach is conservative, and only eyes with very advanced disease are enucleated upfront. Patients are treated with chemotherapy and intensive focal treatments, with the aim of delaying or avoiding radiation therapy and enucleation. For patients with early intraocular stage (Reese-Ellsworth groups I-III and International Groups A-B), the two-drug combination of vincristine and carboplatin is recommended. Patients with more advanced intraocular disease (Reese-Ellsworth groups IV-V and International Groups C-D) require more intensive chemotherapy. Standard of care for these patients incorporates etoposide into the regimen. Effective agents with good intraocular penetration, such as topotecan, are being investigated. Because most failures are secondary to progression of the vitreous seeds, subconjunctival carboplatin is added in cases with poor response of the vitreous tumors. Patients must be monitored very closely, with examinations under anesthesia every 4 to 6 weeks, and focal treatments are applied during the procedure. These include cryotherapy for small anterior tumors, thermotherapy and laser photocoagulation for small posterior tumors, and brachytherapy for larger tumors. New treatment approaches under development include the refinement of periocular chemotherapy administration using slow-release devices, the use of suicide gene therapy with local delivery of the herpes simplex thyrosine kinase gene (followed by systemic administration of ganciclovir), and the development of small-molecule inhibitors of the MDMX-p53 interaction.

Abstract
Although external-beam radiation therapy (EBRT) has been an effective treatment modality in patients with bilateral advanced retinoblastoma, it significantly increases the risk of second malignancies and facial deformities. This study aimed to evaluate the efficacy of tandem high-dose chemotherapy and autologous stem cell rescue (HDCT/ASCR) for treatment, instead of EBRT, in children with bilateral advanced retinoblastoma. Fourteen patients with bilateral retinoblastoma received chemotherapy, and local therapy was provided whenever possible. When at least one functional eye could not be saved by chemoreduction and local therapy, tandem HDCT/ASCR was provided to avoid EBRT. As a result, nine patients received tandem HDCT/ASCR. The toxicities were tolerable and there was no TRM. All nine patients who received tandem HDCT/ASCR had at least one functional eye without EBRT, and in two patients, both eyes were saved. No second malignancy has developed to date. HDCT/ASCR might be an effective treatment for bilateral advanced retinoblastoma, especially in cases in which at least one functional eye could not be preserved with chemoreduction and local therapy alone, and where EBRT was unavoidable. Long-term follow-up and further studies are needed to evaluate the efficacy and toxicity of HDCT/ASCR as an alternative treatment to EBRT.

Abstract
Following from the publication of the International Retinoblastoma Staging System, an open internet discussion group was created at the www.cure4kids.org resource. The results of a survey distributed among participants are discussed. Although most patients with retinoblastoma were treated under prospective protocols, there was a wide variation in the definition of risk criteria and in the criteria for giving adjuvant chemotherapy following enucleation. Definition of high-risk histological features and the criteria for use of adjuvant therapy will be standardized in future studies. Internet meetings are a valuable mechanism for enabling participation from under-resourced countries in the development of cooperative studies.

Abstract
OBJECTIVE To assess the outcome and determine risk factors for extraocular relapse in patients with retinoblastoma who had been enucleated after failure of chemoreduction. METHODS Retrospective study (1995-2002) at three institutions. Pathological risk factors (PRF) were defined as invasion of the anterior segment, choroid, post-laminar optic nerve, subarachnoid space, or sclera according to the local pathology report. Extraocular relapse was defined as an event. RESULTS One hundred twenty-two patients were included (17 had bilateral enucleation). Chemoreduction included vincristine, carboplatin, and etoposide (n=80, 65.6%), vincristine, and carboplatin (n=17, 13.9%), or carboplatin (n=25, 20.5%). Thirty-five also received external beam radiotherapy (28.7%). PRF included: 39 with choroidal involvement, 9 with anterior segment, 9 with scleral, and 2 with post-laminar optic nerve with subarachnoid invasion. Adjuvant chemotherapy was given to eight patients (6.5%) because of scleral invasion. Four patients had an extraocular relapse after enucleation, two of whom survive after intensive treatment including stem cell rescue. Five-year probability of event-free survival is 0.96. Only scleral invasion and bilateral enucleation were significantly associated with extraocular relapse. CONCLUSIONS The risk of extraocular relapse is low after enucleation following failure of chemoreduction. Patients who underwent bilateral enucleation and those with scleral invasion are at higher risk of extraocular relapse.

Abstract
Trilateral retinoblastoma (TRb) is a well-known syndrome associating hereditary retinoblastoma (Rb) with an intracranial neuroblastic tumor arising usually in the pineal region, rarely at the suprasellar or parasellar site. It develops in most cases after diagnosis of Rb. The outcome is usually fatal because of secondary spinal dissemination. Pineal cysts have recently been reported as a benign variant of TRb. We report the unusual presentation of a TRb in a 12-month-old boy with extensive bilateral Rb, a voluminous suprasellar tumor, pineal cyst, and leptomeningeal disease. The special features of this "quadrilateral" Rb are discussed.

Abstract
BACKGROUND Although intra-retinal tumor has long been staged presurgically according to the Reese-Ellsworth (R-E) system, retinoblastoma differs from other pediatric neoplasms in never having had a widely accepted classification system that encompasses the entire spectrum of the disease. Comparisons among studies that consider disease extension, risk factors for extra-ocular relapse, and response to therapy require a universally accepted staging system for extra-ocular disease. PROCEDURE A committee of retinoblastoma experts from large centers worldwide has developed a consensus classification that can encompass all retinoblastoma cases and is presented herein. Patients are classified according to extent of disease and the presence of overt extra-ocular extension. In addition, a proposal for substaging considering histopathological features of enucleated specimens is presented to further discriminate between Stage I and II patients. RESULTS The following is a summary of the classification system developed-Stage 0: Patients treated conservatively (subject to presurgical ophthalmologic classifications); Stage I: Eye enucleated, completely resected histologically; Stage II: Eye enucleated, microscopic residual tumor; Stage III: Regional extension [(a) overt orbital disease, (b) preauricular or cervical lymph node extension]; Stage IV: Metastatic disease [(a) hematogenous metastasis: (1) single lesion, (2) multiple lesions; (b) CNS extension: (1) prechiasmatic lesion, (2) CNS mass, (3) leptomeningeal disease]. A proposal is also presented for substaging of enucleated Stages I and II eyes. CONCLUSIONS The proposed staging system is the product of an international effort to adopt a uniform staging system for patients with retinoblastoma to cover the whole spectrum of the disease.

Abstract
Central nervous system (CNS) involvement is not rare in extraocular retinoblastoma, and it is not surprising to find it in view of its route of spread. However, although spinal recurrence presenting as spinal cord compression (SCC) is a form of CNS involvement, it is extremely rare. This report describes two patients with unilateral retinoblastoma with spinal recurrence presenting as SCC. The first patient developed erythematous swelling of the right foot and weakness of the bilateral lower limbs at 7 months after left enucleation. Examination revealed pitting edema of bilateral feet and muscle power of 2+ to 3+, with intact sensory function. The second patient developed weakness of the bilateral lower limbs, and defecative and urinary difficulty for 2 days at 8 months after left enucleation. Examination revealed pitting edema of bilateral feet and muscle power of 2+, with defective sensory function. Both patients received surgery and local irradiation after SCC. The first patient refused chemotherapy and survived only 4 months due to disease progression. The second patient received systemic and intrathecal chemotherapy, and survived 19.5 months without disease progression. Spinal recurrence with SCC should be suspected when leg weakness or bowel or bladder disturbance occurs in patients with retinoblastoma.

Abstract
There is general agreement that bone marrow (BM) examination for staging in patients with retinoblastoma should be limited to cases with advanced disease. However, there are limited data about the yield of sampling multiple sites with aspirations and biopsies and immunocytology. Our policy for BM examination included: 2 aspirates and 2 biopsies at the posterior iliac crest scheduled only for cases with postlaminar optic nerve extension (n=56), scleral invasion (n=10) or orbital (n=5) or metastatic disease at diagnosis (n=7) or at extraocular relapse (n=18). Immunocytology with the antibodies 3A7 or 3F8 for the ganglioside GD2 was performed. From 1/1994 to 3/2005, 277 newly diagnosed patients and 5 at extraocular relapse were included. BM invasion was not found in any of the 66 patients enucleated with disease confined to the globe, but was found in 11/27 of those with overt extraocular disease. There were 2/11 cases with at least 1 negative aspirate with positive biopsy and/or immunocytology for GD2. GD2 positivity was found in 9/9 cases. A more aggressive BM evaluation has a low yield in enucleated patients with high-risk features but disease limited to the globe. However, in cases with overt extraocular dissemination, the use of BM biopsy and immunocytology for GD2 allowed for the detection of cases that would have been missed by aspirations alone. GD2 was intensively expressed and it may also be used to monitor disease response and the presence of minimal residual disease.

Abstract
BACKGROUND Bone marrow involvement in retinoblastoma patients is rare in the more industrialized nations. The purpose of the current study was to determine the frequency of bone marrow involvement in our series of retinoblastoma patients and to investigate whether the use of four bone marrow aspirates (BMA) and two bone marrow biopsies (BMB) has greater sensitivity for the detection of metastatic disease compared to what has been previously reported. METHODS Retrospective analysis of the charts of 54 patients with retinoblastoma was performed. We performed 265 BMA, 134 BMB (4 aspirates and 2 biopsies per evaluation), and 67 lumbar punctures (LPs) in 54 patients with retinoblastoma. RESULTS There were no patients found with bone marrow or cerebrospinal fluid (CSF) involvement at the time of the initial diagnosis. Although no patient died of distant metastases, two patients developed metastatic disease at recurrence, involving the bone marrow and other sites. For these two patients all four aspirates and two biopsies were positive for disease at the time of recurrence. CONCLUSIONS Despite the use of four BMA and two BMB (as opposed to one bone marrow aspirate that is routinely performed in other centers), the detection of patients with metastatic disease was similar to what has been previously reported. Based on these data more aggressive evaluation of the bone marrow in retinoblastoma patients with clinically limited disease using four aspirates and two biopsies cannot be supported.

Abstract
The prognosis of patients with metastatic retinoblastoma is poor with conventional chemotherapy and radiation. Since retinoblastoma is highly chemosensitive, dose-escalation of chemotherapeutic agents with stem cell support should be promising. We report our experience with high-dose chemotherapy (HDC) and autologous stem cell transplantation (SCT) in patients with metastatic retinoblastoma. Five patients with metastatic retinoblastoma underwent HDC with autologous SCT following conventional chemotherapy and local radiation therapy. Stem cells (bone marrow in four and peripheral blood stem cells in one) were collected after marrow involvement was cleared. Melphalan was a key drug in all patients, and was administered in combination with other agents such as cisplatin, cyclophosphamide, carboplatin or thiotepa. Three patients are currently alive disease-free at 113, 107 and 38 months, respectively, from the time of SCT. They had no central nervous system (CNS) involvement. The two patients who died of disease had CNS involvement. No long-term sequelae of HDC have been noted. Our treatment strategy using HDC appears to be effective for treating metastatic retinoblastoma without CNS involvement.

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
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
Extraocular retinoblastoma is associated with a very poor outcome. At Children's Hospital Los Angeles, 10 of 207 patients with retinoblastoma had extraocular disease. Four patients with no histopathologic risk factors developed extraocular disease. All patients with direct extension into the central nervous system or with distant metastatic disease died. One of three patients with trilateral retinoblastoma and one patient with regional recurrence are alive after autologous bone marrow transplant. Patients with extraocular retinoblastoma who achieve remission may benefit from consolidation of their therapy with autologous bone marrow transplant.
