Abstract
Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.The RMS2005 study included two phase III randomized trials for high-risk (HR) and observational trials for low (LR), standard (SR), and very high-risk (VHR) patients who have been partially reported. Herein, we present a comprehensive report of results achieved for the complete unselected nonmetastatic cohort and analyze the evolution of treatment in comparison with previous European protocols. After a median follow-up of 73.1 months, the 5-year event-free survival (EFS) and overall survival (OS) of the 1,733 patients enrolled were 70.7% (95% CI, 68.5 to 72.8) and 80.4% (95% CI, 78.4 to 82.3), respectively. The results by subgroup: LR (80 patients) EFS 93.7% (95% CI, 85.5 to 97.3), OS 96.7% (95% CI, 87.2 to 99.2); SR (652 patients) EFS 77.4% (95% CI, 73.9 to 80.5), OS 90.6% (95% CI, 87.9 to 92.7); HR (851 patients) EFS 67.3% (95% CI, 64.0 to 70.4), OS 76.7% (95% CI, 73.6 to 79.4); and VHR (150 patients) EFS 48.8% (95% CI, 40.4 to 56.7), OS 49.7% (95% CI, 40.8 to 57.9). The RMS2005 study demonstrated that 80% of children with localized rhabdomyosarcoma could be long-term survivors. The study has established the standard of care across the European pediatric Soft tissue sarcoma Study Group countries with the confirmation of a 22-week vincristine/actinomycin D regimen for LR patients, the reduction of the cumulative ifosfamide dose in the SR group, and for HR disease, the omission of doxorubicin and the addition of maintenance chemotherapy.

Abstract
Introduction: Pain is the main symptom described in cancer patients. Objective: To assess pain classification and management in pediatric patients with primary bone cancer over time: admission, during treatment and follow-up, and to investigate factors associated with pain classification at the last assessment. Method: Retrospective cohort study of osteosarcoma and Ewing's sarcoma cases in individuals <19 years old treated at a single cancer referral site and followed up by a multidisciplinary team. The primary endpoint was pain score at the last assessment. Secondary outcome: evolution of pharmacological treatment. Results: 142 patients were included. The frequency of pain assessment increased during the study period from 53.5% at admission to 68.3% during treatment and 85.9% in follow-up. Of the patients who had pain assessed, 65.8% had pain at admission and 26.2% at the end of the study. There was an increase in the use of strong opioids and antidepressants. In the last evaluation, 56 patients (39.4%) were at the end-of-life and this was not associated with more pain (p=0.68). Meanwhile, those who had more pain used strong opioids (p=0.01) or steroids (p=0.03). Conclusion: Pain management during treatment resulted in increased use of strong opioids and antidepressants with pain reduction, revealing that pain control is possible. In the last assessment, end-of-life patients no longer had pain and patients with pain were the ones who used strong opioids and steroids at the most, showing the difficulty of pain control in some patients.

Abstract
PURPOSE Outcome for patients with metastatic rhabdomyosarcoma (RMS) is poor. This study presents the results of the MTS 2008 study with a pooled analysis including patients from the concurrent BERNIE study. PATIENTS AND METHODS In MTS 2008, patients with metastatic RMS received four cycles of ifosfamide, vincristine, and actinomycin D (IVA) plus doxorubicin, five cycles of IVA, and 12 cycles of maintenance chemotherapy (low-dose cyclophosphamide and vinorelbine). The BERNIE study randomly assigned patients to the addition or not of bevacizumab to the same chemotherapy. Local therapy (surgery/radiotherapy) was given to the primary tumor and all metastatic sites when feasible. RESULTS MTS 2008 included 270 patients (median age, 9.6 years; range, 0.07-20.8 years). With a median follow-up of 50.3 months, 3-year event-free survival (EFS) and overall survival (OS) were 34.9% (95% CI, 29.1 to 40.8) and 47.9% (95% CI, 41.6 to 53.9), respectively. In pooled analyses on 372 patients with a median follow-up of 55.2 months, 3-year EFS and OS were 35.5% (95% CI, 30.4 to 40.6) and 49.3% (95% CI, 43.9 to 54.5), respectively. Patients with ≤ 2 Oberlin risk factors (ORFs) had better outcome than those with ≥ 3 ORFs: 3-year EFS was 46.1% versus 12.5% (P < .0001) and 3-year OS 60.0% versus 26.0% (P < .0001). Induction chemotherapy and maintenance appeared tolerable; however, about two third of patients needed dose adjustments during maintenance. CONCLUSION Outcome remains poor for patients with metastatic RMS and multiple ORFs. Because of the design of the studies, it was not possible to determine whether the intensive induction regimen and/or the addition of maintenance treatment resulted in apparent improvement of outcome compared with historical cohorts. Further studies, with novel treatment approaches are urgently needed, to improve outcome for the group of patients with adverse prognostic factors.

Abstract
PURPOSE In the last few decades, interest in palliative care and advance care planning has grown in Brazil and worldwide. Empirical studies are needed to reduce therapeutic obstinacy and medical futility in the end-of-life care of children with incurable cancer. The aim of this study was to investigate the effects of do-not-resuscitate-like (DNRL) orders on the quality of end-of-life care of children with incurable solid tumors at a cancer center in Brazil. METHODS A retrospective observational cohort study of 181 pediatric patients with solid tumors followed at the Pediatric Oncology Department of the Brazilian National Cancer Institute, Rio de Janeiro, Brazil, who died due to disease progression from 2009 to 2013. Medical records were reviewed for indicators of quality of end-of-life care, including overtreatment, care planning, and care at death, in addition to documentation of the diagnosis of life-limiting illness and the presence of a DNRL order. Data were summarized using descriptive statistics. Univariate and multivariate logistic regression analyses were used to examine associations between demographics, disease, treatment, and indicators of end-of-life care with a DNRL order. RESULTS A documented DNRL order was associated with lower odds of dying in the intensive care unit or emergency room (80%), dying within 30 days of endotracheal tube placement (80%), or cardiopulmonary resuscitation (CPR) administration at the time of death (96%). CONCLUSION Placement of DNRL orders early in the disease process is critical in reducing futile treatment in pediatric patients with incurable cancer.

Abstract
BACKGROUND Medulloblastoma (MB),the most common malignant brain tumor of childhood has survival outcomes exceeding 80% for standard-risk and 60% for high-risk patients in high-income countries (HICs). These results have not been replicated in low- and middle-income countries (LMICs), where 80% of children with cancer live. METHODS This is a retrospective review of 114 children aged 3-18 years diagnosed with MB from 1997 to 2016 at National Cancer Institute (INCA). Sociodemographic, clinical, and treatment data were extracted from the medical records and summarized descriptively. Overall survival (OS) and progression-free survival (PFS) were calculated using the Kaplan-Meier method. RESULTS The male-to-female ratio was 1.32 and the median age at diagnosis was 8.2 years. Headache (83%) and nausea/vomiting (78%) were the most common presenting symptoms. Five-year OS was 59.1% and PFS was 58.4%. The OS for standard-risk and high-risk patients was 69% and 53%, respectively. The median time to diagnosis interval was 50.5 days and the median time from surgery to radiation therapy initiation was 50.4 days. Patients who lived >40 km from INCA fared better (OS = 68.2% vs. 51.1%, p = .032). Almost 20% of families lived below the Brazilian minimum wage. Forty-five patients (35%) had metastatic disease at admission. Gross total resection was achieved in 57% of the patitents. CONCLUSIONS Although there are considerable barriers to deliver effective MB treatment in countries like Brazil, the OS seen in the present study demonstrates that good outcomes are not only feasible but can and should be increased with appropriate interventions.

Abstract
BACKGROUND Changesin nutritional status can constitute a risk factor for reduced tolerance and effectiveness of antineoplastic treatment. Knowledge of the nutritional status of pediatric patients is important for implementing interventions to improve outcomes. We aimed to evaluate nutritional status at diagnosis and throughout therapy in pediatric patients with solid tumors. OBJECTIVES To study the prevalence of malnutrition at diagnosis, compare different assessment tools, and examine longitudinal changes in nutritional status during the treatment of pediatric patients with solid tumors in a Brazilian institution. METHODS This prospective single-center study enrolled patients with solid tumors (age <19 years) from June 2017 to May 2018. Nutritional evaluations were performed at diagnosis and after 3 and 6 months of treatment. z-Scores for height for age (H/A) and body mass index for age (BMI/A) were calculated using the Anthro/AnthroPlus software and mid-upper arm circumference (MUAC) percentile was used for nutritional classification. RESULTS The prevalence of nutritional status at diagnosis was 29.3% malnourished, 49.5% adequate, and 21.2% overweight/obese. Nutritional status improved during the first 3 months of treatment, with a reduction in the proportion of malnourished patients and an increased number of patients with adequate nutritional status. CONCLUSIONS The two combined indices, BMI/A and MUAC, facilitated the diagnosis of a greater number of patients with solid tumors who had nutritional alterations. A high prevalence of malnutrition was present at diagnosis. Nutritional status improved in the first 3 months of treatment and could be related to the multidisciplinary institutional approach following the diagnosis.

Abstract
BACKGROUND Little is known about socioeconomic status (SES) and its effects in childhood cancer survival. This study aims to discuss the association between SES and survival of patients with retinoblastoma (RB) from a tertiary treatment center. PROCEDURE A retrospective cohort study was conducted, including all patients with RB referred to the Brazilian National Institute of Cancer in Rio de Janeiro (January 2000-December 2016). RESULTS Data from 160 patients were analyzed with mean age at diagnosis of 22.85 months (SD ± 14.29). Eighty-three patients (51.9%) had an interval to diagnosis equal to or longer than six months, and 13 children (8.1%) abandoned treatment. Five-year overall survival rate for all patients was 78.8% (95% CI, 72.4%-85.9%). In a multivariate model, patients whose fathers had more than nine years of study had a lower death risk. Patients from families having more than one child under five years had a 213% higher risk of death compared with those living with no other small child. Treatment abandonment also had a profound effect on death risk. CONCLUSION Childhood cancer is notably important considering the potential years of life lost. RB has even more important elements, as the possibility of vision loss in cases with delayed diagnosis. Family characteristics seem to be highly related to RB survival, especially in low- and middle-income countries, where inequalities are still a public health issue. Strategies to improve survival should focus not only on large-scale settings such as improving national healthcare systems but also on more personalized actions that might help to mitigate disparities.

Abstract
Surgery consists in the mainstay of treatment in most gliomas, but in many cases, a resection is not feasible. Liquid biopsy is an ideal tool providing a minimally invasive method through plasma or CSF sampling to assess cell-free tumor DNA (ctDNA). Here we explore the feasibility of detecting DNA in plasma exosomes (exoDNA) extracted from glioma patients and further investigate its use in identifying molecular alterations. Exosomes were isolated from 2ml of plasma from 24 patients (13 LGG, 8 HGG, 3 DIPG) and fully characterized by nanoparticle tracking analysis and transmission electron microscopy. DNA was extracted from 13 samples (exoDNA) so far. Five patients had confirmed point mutations in the primary tumor (3BRAFV600E; 1FGFR1N546K; 1H3.3), additionally, 3 samples were collected from clinically diagnosed DIPG patients to inquire H3K27M mutations. DNA was extracted successfully from all exosome samples; a pre-amplification step was needed and direct sequencing was carried out for BRAFV600E. FGFR1N546K and H3K27M mutations were sought in patients with positive tumors. Wildtype BRAF fragment was identified in 12/13samples (1 patient failed sequencing). However, none of the five tumor positive patients nor the DIPG patients had mutations detected at the exo-DNA level. There is growing evidence that CSF may be the ideal source of ctDNA in brain tumor patients, therefore although we could not detect mutations in plasma DNA we are currently analyzing CSF exoDNA and cell-free DNA to evaluate if this proves a successful strategy and weather exoDNA is more representative of the tumor content.

Abstract
PURPOSE To describe the incidence and risk factors of communication, swallowing, and orofacial myofunctional disorders in a cohort of children and adolescents with cancer and benign neoplasms. METHODS A prospective cohort study conducted with children aged ⩾ 2 years and adolescents of both genders admitted at the Pediatric Oncology Department of the Instituto Nacional de Câncer (INCA) between March 2014 and April 2015. Study participants were submitted to a Speech-Language Pathology (SLP) assessment at three different times: (T1) at hospital admission; (T2) six months after admission; (T3) one year after admission. RESULTS One hundred and sixty individuals were evaluated. At the time of hospital admission, 68 individuals (42.5%) presented with some type of SLP disorder. After one year of follow-up, 22.8% of the patients had developed new impairments. The occurrence of new speech-language disorders had a statistically significant association with the tumor site. In the risk analysis for the development of speech-language disorders with respect to the primary tumor site, compared to other sites, the central nervous system (CNS) tumor group was 8.29 times more likely to present some new alterations, while the head and neck (HN) tumor group had a 10.36-fold higher risk. CONCLUSION An incidence of 22.8% for communication, swallowing, and orofacial myofunctional disorders was observed. The development of these disorders was greater in individuals with tumors in the CNS and in the HN region.

Abstract
BACKGROUND For more than three decades, standard treatment for rhabdomyosarcoma in Europe has included 6 months of chemotherapy. The European paediatric Soft tissue sarcoma Study Group (EpSSG) aimed to investigate whether prolonging treatment with maintenance chemotherapy would improve survival in patients with high-risk rhabdomyosarcoma. METHODS RMS 2005 was a multicentre, open-label, randomised, controlled, phase 3 trial done at 102 hospitals in 14 countries. We included patients aged 6 months to 21 years with rhabdomyosarcoma who were considered to be at high risk of relapse: those with non-metastatic incompletely resected embryonal rhabdomyosarcoma occurring at unfavourable sites with unfavourable age (≥10 years) or tumour size (>5 cm), or both; those with any non-metastatic rhabdomyosarcoma with nodal involvement; and those with non-metastatic alveolar rhabdomyosarcoma but without nodal involvement. Patients in remission after standard treatment (nine cycles of ifosfamide, vincristine, dactinomycin with or without doxorubicin, and surgery or radiotherapy, or both) were randomly assigned (1:1) to stop treatment or continue maintenance chemotherapy (six cycles of intravenous vinorelbine 25 mg/m2 on days 1, 8, and 15, and daily oral cyclophosphamide 25 mg/m2, on days 1-28). Randomisation was done by use of a web-based system and was stratified (block size of four) by enrolling country and risk subgroup. Neither investigators nor patients were masked to treatment allocation. The primary outcome was disease-free survival in the intention-to-treat population. Secondary outcomes were overall survival and toxicity. This trial is registered with EudraCT, number 2005-000217-35, and ClinicalTrials.gov, number NCT00339118, and follow-up is ongoing. FINDINGS Between April 20, 2006, and Dec 21, 2016, 371 patients were enrolled and randomly assigned to the two groups: 186 to stop treatment and 185 to receive maintenance chemotherapy. Median follow-up was 60·3 months (IQR 32·4-89·4). In the intention-to-treat population, 5-year disease-free survival was 77·6% (95% CI 70·6-83·2) with maintenance chemotherapy versus 69·8% (62·2-76·2) without maintenance chemotherapy (hazard ratio [HR] 0·68 [95% CI 0·45-1·02]; p=0·061), and 5-year overall survival was 86·5% (95% CI 80·2-90·9) with maintenance chemotherapy versus 73·7% (65·8-80·1) without (HR 0·52 [95% CI 0·32-0·86]; p=0·0097). Toxicity was manageable in patients who received maintenance chemotherapy: 136 (75%) of 181 patients had grade 3-4 leucopenia, 148 (82%) had grade 3-4 neutropenia, 19 (10%) had anaemia, two (1%) had thrombocytopenia, and 56 (31%) had an infection. One (1%) patient had a grade 4 non-haematological toxicity (neurotoxicity). Two treatment-related serious adverse events occurred: one case of inappropriate antidiuretic hormone secretion and one of a severe steppage gait with limb pain, both of which resolved. INTERPRETATION Adding maintenance chemotherapy seems to improve survival for patients with high-risk rhabdomyosarcoma. This approach will be the new standard of care for patients with high-risk rhabdomyosarcoma in future EpSSG trials.

Abstract
BACKGROUND High rates of treatment abandonment have been considered one of the major limitations to achieving high cure rates of childhood cancer in developing countries. The aims of this study were to report the prevalence and factors associated with treatment abandonment for children diagnosed with solid tumors in one reference center in Brazil and to describe effective strategies to prevent it. PROCEDURES A retrospective review was conducted using data from 1139 children (0-18 years) treated for solid tumors at the Brazilian National Cancer Institute, during the period between January 2012 and December 2017. Treatment abandonment was defined as recommended by the International Society of Pediatric Oncology. The impact of implementing a patient-tracking system was evaluated. Descriptive statistics were used to analyze patient characteristics. Chi-square test was used for statistical analysis, with the significance level <0.05. RESULTS Of 1139 patients, 1.66% refused or abandoned treatment. Although from 2012 to 2013 there was an increase in the abandonment rate, it then decreased by 63.8% from 2013 to 2017 (2.5% to 0.9%). In the multivariate model, only retinoblastoma diagnosis was associated with abandonment (odds ratio = 5.0; 95% confidence interval, 1.2-20.4; P = 0.025). In our cohort, abandonment rates were not associated with increased death. CONCLUSION Monitoring missed appointments, and early interventions to address issues associated with providing resources to help families during treatment were effective in achieving very low abandonment rates.

Abstract
OBJECTIVE Rhabdomyosarcoma (RMS) represents the most common soft tissue sarcoma that affects children. Treatment involves chemoradiotherapy. This study aimed at evaluating the long-term alterations to teeth and cranial bones in children, teenagers, and young adults after oncologic treatment. STUDY DESIGN We conducted a cross-sectional study of patients undergoing treatment for head and neck RMS between 1988 and 2011. We evaluated demographic, clinical, and treatment data and performed panoramic radiography, cephalometry, and photography. RESULTS We evaluated 27 long-term survivors, most of whom had been treated between ages 0 to 5 years (51.9%). The total radiation dose applied was 50.4 Gy, and the chemotherapy combination included vincristine, actinomycin D, and cyclophosphamide in 51.9% of the cases. We observed 603 dental alterations, among which 377 (62.7%) occurred in patients ages 0 to 5 years, and root shortening was the most frequent alteration observed (24.2%). With regard to facial bones, 74% of the patients had some level of facial asymmetry, 70.4% had reduced facial depth, 48.4% had mandibles of short size, and 77.8% had reduced facial height. CONCLUSIONS Children submitted to RMS treatment involving chemotherapy and radiotherapy displayed significant dental and craniofacial alterations, especially when treatment occurred between ages 0 and 5 years.

Abstract
BACKGROUND Alveolar rhabdomyosarcoma (aRMS) with lymph node involvement (N1 classification) accounts for up to 10% of all cases of RMS. The prognosis is poor, and is comparable to that of distant metastatic disease. In the European Paediatric Soft Tissue Sarcoma Study Group (EpSSG) RMS2005 protocol, patients with a histologic diagnosis of aRMS/N1 received intensified chemotherapy with systematic locoregional treatment. METHODS Patients with aRMS/N1 were enrolled prospectively after primary surgery/biopsy and fusion status was assessed in tumor samples. All patients received 9 cycles of induction chemotherapy and 6 months of maintenance therapy. Local treatment included radiotherapy to the primary site and lymph nodes with or without secondary surgical resection. RESULTS A total of 103 patients were enrolled. The clinical characteristics of the patients were predominantly unfavorable: 90% had macroscopic residual disease after initial surgery/biopsy, 63% had locally invasive tumors, 77% had a tumor measuring >5 cm, and 81% had disease at unfavorable sites. Fusion genes involving forkhead box protein O1 (FOXO1) were detected in 56 of 84 patients. Events occurred in 52 patients: 43 developed disease recurrence, 7 had disease that was refractory to treatment, and 2 patients developed second neoplasms. On univariate analysis, unfavorable disease site, tumor invasiveness, Intergroup Rhabdomyosarcoma Study group III, and fusion-positive status correlated with worse prognosis. The 5-year event-free survival rate of patients with fusion-positive tumors was 43% compared with 74% in patients with fusion-negative tumors (P = .01). On multivariate analysis, fusion positivity and tumor invasiveness proved to be unfavorable prognostic markers. CONCLUSIONS Fusion status and tumor invasiveness appear to have a strong impact on prognosis in patients with aRMS/N1. Fusion status will be used to stratify these patients in the next EpSSG RMS study, and treatment will be intensified in patients with fusion-positive tumors.

Abstract
PURPOSE Describe the prevalence of communication, swallowing and orofacial myofunctional disorders in a group of children and adolescents at the time of registration at a cancer hospital. METHODS A cross-sectional study conducted with children aged ≥2 and adolescents, of both genders, admitted to the Pediatric Oncology Section of the Instituto Nacional de Câncer José de Alencar Gomes da Silva (INCA) from March 2014 to April 2015 for investigation and/or treatment of solid tumors. A protocol was used to record the sociodemographic and clinical information and findings of the speech-language pathology clinical evaluation, which included aspects of the oral sensorimotor system, swallowing, speech, language, voice, and hearing. RESULTS Eighty-eight children/adolescents (41.3%) presented some type of speech-language disorder. The most frequent speech-language disorders were orofacial myofunctional disorder, dysphonia, and language impairments, whereas the less frequent ones were dysacusis, tongue paralysis, and trismus. Site of the lesion was the clinical variable that presented statistically significant correlation with presence of speech-language disorders. CONCLUSION High prevalence of speech-language disorders was observed in children and adolescents at the time of admission at a cancer hospital. Occurrence of speech-language disorders was higher in participants with lesions in the central nervous system and in the head and neck region.

Abstract
RESUMO O presente trabalho é um relato de caso que descreve os achados fonoaudiológicos e de qualidade de vida apresentados por uma adolescente com um tumor do sistema nervoso central acometida pela mielinólise extrapontina. A mielinólise extrapontina é uma doença desmielinizante aguda que pode ser causada por variações abruptas na osmolaridade sérica, como o que ocorre na rápida correção da hiponatremia. Os dados foram obtidos a partir da avaliação clínica fonoaudiológica, de questionários pediátricos sobre a qualidade de vida e dados contidos no prontuário médico. A paciente apresentou mutismo, disartria e disfagia decorrentes da mielinólise extrapontina, com impactos significativos na sua comunicação verbal, alimentação e qualidade de vida. Os escores de qualidade de vida após a mielinólise extrapontina apresentaram piora quando comparados aos do período anterior à doença. Recebeu atendimento fonoaudiológico hospitalar e ambulatorial. Foram observadas evoluções nos padrões de fala, deglutição e mobilidade das estruturas orofaciais, com reversão parcial dos déficits neurológicos. A atuação fonoaudiológica, como parte de uma equipe multiprofissional de saúde, é de grande importância na reabilitação funcional dos pacientes acometidos por esta doença.

Abstract
BACKGROUND Metronomic chemotherapy (MC) consists of the administration of a low dose of chemotherapy on a daily or weekly basis without a long break to achieve an antitumoral effect through an antiangiogenic effect or stimulation of the immune system. The potential effect of MC with continuous oral cyclophosphamide and methotrexate in patients with high-grade operable osteosarcomas (OSTs) of the extremities was investigated. METHODS Patients with high-grade OSTs who were 30 years old or younger were eligible for registration at diagnosis. Eligibility for randomization included 1) nonmetastatic disease and 2) complete resection of the primary tumor. The study design included a backbone of 10 weeks of preoperative therapy with methotrexate, adriamycin, and platinum (MAP). After surgery, patients were randomized between 2 arms to complete 31 weeks of MAP or receive 73 weeks of MC after MAP. The primary endpoint was event-free survival (EFS) from randomization. RESULTS There were 422 nonmetastatic patients registered (May 2006 to July 2013) from 27 sites in 3 countries (Brazil, Argentina and Uruguay), and 296 were randomized to MAP plus MC (n = 139) or MAP alone (n = 157). At 5 years, the EFS cumulative proportions surviving in the MAP-MC group and the MAP-alone group were 61% (standard error [SE], 0.5%) and 64% (SE, 0.5%), respectively, and they were not statistically different (Wilcoxon [Gehan] statistic = 0.724; P =.395). The multivariate analysis showed that necrosis grades 1 and 2, tumor size, and amputation were associated with shorter EFS. CONCLUSIONS According to the current follow-up, EFS with MAP plus MC is not statistically superior to EFS with MAP alone in patients with high-grade, resectable OSTs of the extremities.

Abstract
Purpose Retinoblastoma is the most common intraocular malignancy of childhood. In most cases, parents are the first to notice leukocoria and other symptoms before undergoing a prolonged period of stress before diagnosis. The purpose of this study was to determine prediagnostic intervals of patients with retinoblastoma at an oncology tertiary center (Instituto Nacional de Cancer) in Rio de Janeiro, Brazil, and relate them to stage at diagnosis, eye salvage, and survival. Methods Parents or caregivers of children with retinoblastoma registered between January 2006 and September 2013 were interviewed using a semistructured individually applied questionnaire, concerning their trajectory before registration. Results Out of 76 patients, 39 (51%) were girls, 52 (68%) had unilateral retinoblastoma, and 24 (32%) had bilateral retinoblastoma, totaling 100 affected eyes. The most common stage of diagnosis was the intraocular group, with 63 (83%) patients; nine (12%) were extraocular, and four (5%) had metastatic disease. During the follow-up time of 37 ± 24.5 months, 10 (13%) patients died and 70 (70%) eyes were enucleated. Mean family interval was 1.6 ± 2.6 months, mean medical interval was 5.0 ± 6.2 months, mean referral interval was 0.2 ± 1.4 months, and mean overall interval was 7.1 ± 6.9 months. In univariate analysis, age at diagnosis, maternal education, medical interval, and overall interval were significantly related to advanced stage at diagnosis and survival. In multivariate analysis, maternal education and medical interval were significantly related to advanced stage at diagnosis and survival. No variables affected eye salvage. Conclusion Medical interval was responsible for 70% of the overall interval; therefore, programs or campaigns targeting retinoblastoma early diagnosis should focus emphasize in medical awareness.

Abstract
Prognostic markers that can help identifying precocious risk of unfavorable outcomes in patients with childhood adrenocortical tumors (ACTs) are still unclear. This observational and retrospective study aimed to identify clinical and pathology prognostic factors of recurrence and death in a tertiary cancer center population. Clinical, pathology, demographic, staging, and therapy data from patients with childhood ACT (median age: 3.6 years) treated at the Brazilian National Institute of Cancer between 1997 and 2015 were assessed. Univariate and bivariate analyses were used to study the association of clinical and pathology characteristics with recurrence and mortality. Recurrence and disease-related mortality were the main outcomes. Twenty-seven patients were included. Complete tumor resection was performed in 21 cases. The median tumor size was 8.2 cm. Mitotane was the most common adjuvant/palliative therapy (n = 13). Recurrence occurred in 6 patients, after a median time of 7.2 months, and was more common among those with larger tumors (P =.008), higher Weiss score (P =.001), and microscopic tumoral necrosis (P =.002). Ten patients died from the disease. Older age (P =.04), larger tumor size (P =.002), metastatic disease (P =.003), previous recurrence (P =.003), incomplete resection (P =.002), intraoperative tumor spillage (P =.005), higher Weiss score (P =.03), microscopic necrosis (P =.005), and capsular invasion (P =.02) were all associated with increased death risk. Even though complete tumor resection was performed in most cases, a considerable number of cases of childhood ACT resulted in recurrence and death. Early identification of unfavorable outcomes is essential to determine ideal therapy and appropriate surveillance.

Abstract
AIM To obtain baseline knowledge about the current use of intra-arterial chemotherapy (SSOAIC) in centers worldwide. METHODS A survey including questions about the use of SSOAIC was emailed to retinoblastoma experts. RESULTS Seventy-nine (response rate 69.9%) doctors from 63 centers in 35 countries responded. Thirty-one centers from 19 countries use SSOAIC. Twelve performed more than 50 procedures. Melphalan is the most commonly used drug but 15 centers use more than one drug. First line therapy for advanced unilateral disease is the most common use of SSOAIC (74.2%). Centers with larger experience (>50 applications) were less likely using melphalan alone (P=0.06) and significantly more likely using SSOAIC in more situations such as second line in preference to radiotherapy P=0.05. Nineteen (61.2%) stated that SSOAIC improved their results and 21 (77.8%) reported less toxicity compared to other treatments. Three centers reported that SSOAIC did not improve their results. There were regional variations in the use of SSOAIC which is used more frequently as secondary treatment in Europe compared to the USA and Japan. Ten centers identified cost is the major limiting factor for SSOAIC. CONCLUSION SSOAIC is used in an increasing number of centers worldwide with regional variations. Centers with more experience in SSOAIC use it in more situations including other drugs than melphalan. The majority of the centers using this technique reported improved results and few complications.

Abstract
OBJECTIVES Childhood cancer mortality has substantially declined worldwide as a result of significant advances in global cancer care. Because limited information is available in Brazil, we analyzed trends in childhood cancer mortality in five Brazilian regions over 29 years. METHODS Data from children 0-14 years old were extracted from the Health Mortality Information System for 1979 through 2008. Age-adjusted mortality rates, crude mortality rates, and age-specific mortality rates by geographic region of Brazil and for the entire country were analyzed for all cancers and leukemia. Mortality trends were evaluated for all childhood cancers and leukemia using joinpoint regression. RESULTS Mortality declined significantly for the entire period (1979-2008) for children with leukemia. Childhood cancer mortality rates declined in the South and Southeast, remained stable in the Middle West, and increased in the North and Northeast. Although the mortality rates did not unilaterally decrease in all regions, the age-adjusted mortality rates were relatively similar among the five Brazilian regions from 2006-2008. CONCLUSIONS Childhood cancer mortality declined 1.2 to 1.6% per year in the South and Southeast regions.

Abstract
The most frequent epigenetic alterations in Wilms tumor (WT) occur at WT2, assigned to 11p15. WT2 consists of two domains: telomeric domain 1 (DMRH19) that contains the IGF2 gene and an imprinted maternally expressed transcript (H19) and centromeric domain 2 (KvDMR) that contains the genes KCNQ1, KCNQ1OT1 and CDKN1C. In this work, we used pyrosequencing and MS-MLPA to compare the methylation patterns of DMRH19/KvDMR in blood and tumor samples from 40 WT patients. Normal constitutional KvDMR methylation indicated that most of the epigenetic alterations in WT occur at DMRH19. Constitutional DMRH19 hypermethylation (HM DMRH19) was observed in two patients with Beckwith-Wiedemann syndrome. Pyrosequencing and MS-MLPA showed HM DMRH19 in 28/34 tumor samples: 16/34 with isolated HM DMRH19 and 12/34 with concomitant HM DMRH19 and KvDMR hypomethylation, indicating paternal uniparental disomy. With the exception of one blood sample, the MS-MLPA and pyrosequencing findings were concordant. Diffuse or focal anaplasia was present in five tumor samples and was associated with isolated somatic HM DMRH19 in four of them. Constitutional 11p15 methylation abnormalities were present in 5% of the samples and somatic abnormalities in the majority of tumors. Combined analysis of DMRH19/KvDMR by pyrosequencing and MS-MLPA is beneficial for characterizing epigenetic anomalies in WT, and MS-MLPA is useful and reliable for estimation of DNA methylation in a clinical setting.

Abstract
Wilms' tumor (WT) is a heterogeneous neoplasia characterized by a number of genetic abnormalities, involving tumor suppressor genes, oncogenes and genes related to the Wnt signaling pathway. Somatic biallelic inactivation of WT1 is observed in 5-10% of sporadic WT. Somatic mutations in exon 3 of CTNNB1, which encodes β-catenin, were initially observed in 15% of WT. WTX encodes a protein that negatively regulates the Wnt/β-catenin signaling pathway and mediates the binding of WT1. In this study, we screened germline and somatic mutations in selected regions of WT1, WTX and CTNNB1 in 43 WT patients. Mutation analysis of WT1 identified two single-nucleotide polymorphisms, one recurrent nonsense mutation (p.R458X) in a patient with proteinuria but without genitourinary findings of Denys-Drash syndrome (DDS) and one novel missense mutation, p.C428Y, in a patient with Denys-Drash syndrome phenotype. WT1 SNP rs16754A>G (R369R) was observed in 17/43 patients, and was not associated with significant difference in age at diagnosis distribution, or with 60-month overall survival rate. WTX mutation analysis identified five sequence variations, two synonymous substitutions (p.Q1019Q and p.D379D), a non-synonymous mutation (p.F159L), one frameshift mutation (p.157X) and a novel missense mutation, p.R560W. Two sequence variations in CTNNB1 were identified, p.T41A and p.S45C. Overall survival of bilateral cases was significantly lower (p=0.005). No difference was observed when survival was analyzed among patients with WT1 or with WTX mutations. On the other hand, the survival of two patients with the CTNNB1 p.T41A mutation was significantly lower (p=0.000517) than the average.

Abstract
Background Childhood cancer differs from most common adult cancers, suggesting a distinct aetiology for some types of childhood cancer. Our objective in this study was to test the difference in incidence rates of 4 non-CNS embryonic tumours and their correlation with socioeconomic status (SES) in Brazil. Methods Data was obtained from 13 Brazilian population-based cancer registries (PBCRs) of neuroblastoma (NB), Wilms'tumour (WT), retinoblastoma (RB), and hepatoblastoma (HB). Incidence rates by tumour type, age, and gender were calculated per one million children. Correlations between social exclusion index (SEI) as an indicator of socioeconomic status (SES) and incidence rates was investigated using the Spearman's test. Results WT, RB, and HB presented with the highest age-adjusted incidence rates (AAIRs) in 1 to 4 year old of both genders, whereas NB presented the highest AAIR in ≤11 month-olds. However, differences in the incidence rates among PBCRs were observed. Higher incidence rates were found for WT and RB, whereas lower incidence rates were observed for NB. Higher SEI was correlated with higher incidences of NB (0.731; p = 0.0117), whereas no SEI correlation was observed between incidence rates for WT, RB, and HB. In two Brazilian cities, the incidence rates of NB and RB were directly correlated with SEI; NB had the highest incidence rates (14.2, 95% CI, 8.6-19.7), and RB the lowest (3.5, 95% CI, 0.7-6.3) in Curitiba (SEI, 0.730). In Natal (SEI, 0.595), we observed just the opposite; the highest incidence rate was for RB and the lowest was for NB (4.6, 95% CI, 0.1-9.1). Conclusion Regional variations of SES and the incidence of embryonal tumours were observed, particularly incidence rates for NB and RB. Further studies are necessary to investigate risk factors for embryonic tumours in Brazil.

Abstract
Spindle epithelial tumor with thymus-like element (SETTLE) is a rare malignant neoplasm of the thyroid, occurring predominantly in children, adolescents, and young adults. SETTLE usually presents itself as a thyroid mass, without metastases at diagnosis. It is believed to derive from branchial pouch or thymic remnant tissue showing primitive thymic differentiation. This article reports the clinical, cytological, histological and immunohistochemical features of a SETTLE in a 3-year-old girl. Microscopic exam revealed a nodular, highly cellular neoplasm displayed in the classic biphasic pattern, with mixture of prominent spindle cell component and a minor glandular component lined by mucinous or respiratory-type epithelium. The immunohistochemical study showed strong and diffuse positivity for pan-CK, vimentin and smooth muscle actin. The present case is the first SETTLE case reported in Brazil. To date, the patient described remains without evidence of recurrence or metastasis 5 years after surgery.

Abstract
The Brazilian Population-Based Cancer Registry (PBCR) was started in 1967; today there are 20 PBCRs in Brazil. We report the first descriptive analysis of the incidence of childhood cancer based on data from 14 PBCRs, corresponding to 15% of the child and adolescent population in Brazil. Data were obtained from registry databases, including information on population coverage and data quality indicators. The International Classification of Childhood Cancer was used. Age-adjusted rates were calculated by world population. Incidence by cancer registry, age, sex, and cancer type were calculated per 1,000,000 children. Age-adjusted rates per 1,000,000 children/adolescents ranged from 92 to 220 among the 14 PBCRs. The principal groups of cancers were leukemia, lymphoma and central nervous tumors. The median incidence rate of childhood cancer in the 14 PBCRs was 154.3 per million; children 1-4 years of age had the highest incidence rates. The Brazilian PBCRs provide important information about pediatric cancer incidence in an emerging country. The observed incidence rates of childhood leukemia were similar to previous reported rates, and the age-specific incidence rates of retinoblastoma (0-4 years of age) were higher than those for developed countries. These data can be used as baseline incidence rates of childhood and adolescent cancer in Brazil in future epidemiological studies.

Abstract
Brainstem gliomas constitute 10% of brain tumors in children and less than 2% in adults. Since therapeutic options are limited and brainstem gliomas are associated with a high morbidity and mortality, we sought to analyze the prognostic factors associated with a better outcome. We reviewed the records of 86 patients with brainstem gliomas treated between 1996 and 2006. We recorded demographic and clinical variables as well as radiological findings and survival. Patients were divided in two groups regarding overall survival: late progressors (survival >or=12 months) or early progressors (survival<12 months). Of 86 patients with brainstem gliomas, 55.8% were females. The mean age at diagnosis was 14.2 years (range 1 to 52 years). Twenty-four (27.9%) patients were adults. Lesions were located at pons in 75.6% of patients, midbrain in 15.1% and medulla in 9.3%. There was no difference between early and late progressors concerning gender, age at onset, location at pons, presence of necrosis or contrast enhancement observed at MRI or surgical resection. In both univariate and multivariate analysis, only a short duration of symptoms before diagnosis (<3 months) was associated with a worst prognosis (odds ratio 5.59, 95% CI 1.94 to 16, p=0.0014). A short duration of symptoms, which may imply a more aggressive tumor, was associated with a worst prognosis in patients with brainstem gliomas. This information may be useful in the selection of patients for future therapeutic trials.

Abstract
BACKGROUND Investigating transmission of a constitutive, g78238C > T (R552X), RB1 mutation in four affected children descended from three different unaffected fathers and an unaffected mother. PROCEDURES Sequence data analyses and allele-specific PCR assays were used to investigate the presence of the mutation in four affected children, five unaffected sibs (or half-sibs), and the unaffected mother. Haplotyping was carried out for confirming that the children descended from different fathers. RESULTS Haplotyping excluded the possibility of paternal transmission of a de novo mutation and provided evidence of maternal germline mosaicism. The mutation was apparently absent in blood- and buccal cell-DNA of the mother who also showed a normal fundoscopy. CONCLUSIONS Our findings indicated that mosaicism was restricted to the maternal germline. The mutational event must have occurred at least 4 weeks post-conception, unlike the early mutational events of most mosaics, occurring between fertilization and the 8th day of conception. The implications of these findings are discussed in view that genetic counselling should discriminate between germline mosaicism and de novo events in pseudo-low-penetrant hereditary retinoblastoma.

Abstract
The recent International Symposium on Molecular epidemiology in Embryonal Tumours and Paediatric Leukaemia was held on 4-6 March 2008 in Rio de Janeiro, Brazil. It proved a very productive meeting in which studies relating to genetics, therapeutical trials, identification of risk factors in acute leukaemia neuroblastoma and Wilms' tumours were presented. Over 120 participants gathered for three days of fruitful discussions, including representatives of paediatrics, haematology, laboratory, epidemiology and pathology. Debates were held about strategies of applications of important biomarkers for clinical trials. Highlights of each of the scientific presentations are summarized below.

Abstract
PURPOSE To define a mitotane dose for pediatric patients with adrenocortical cancer (ACC) that maintains therapeutic plasma levels (TL) between 14 and 20 microg/mL and to verify its antitumor efficacy in association with 8 cycles of cisplatin, etoposide, and doxorubicin (CED). METHODS Powdered mitotane was dissolved in a medium chain triglyceride oil and administered to 11 children with ACC (2.4 to 15.4 y of age); an initial low dose was increased to 4 g/m2/d. Ten of the 11 children had a germline TP53 R337H mutation. Mitotane plasma levels were determined using high-performance liquid chromatography. RESULTS The mitotane dose to maintain TL in 7 patients ranged from 1.0 to 5.3 g/m2/d. Six children reached mitotane levels of 10 microg/mL in 3.6 months (1.5 to 5.0 mo), whereas 5 children took 8 months (6.5 to 12.5 mo). Minor to partial tumor remission was found in 5 patients (<1 y) and complete remission was found in 2 patients. Of the 3 patients who are alive at the time of report, 1 patient has been without disease for 16 months, and 2 patients have progressive disease. All patients had recurrent metastatic disease (2 to 9 times). Mitotane toxic effects were nausea, diarrhea, vomiting, neurologic alterations, gynecomastia, a rare case of hypertensive encephalopathy, and CED-related hematologic toxic effects. CONCLUSIONS Mitotane daily dose to maintain TL is variable and monitoring should start 1.5 months after the beginning of treatment. CED combined with mitotane is the best available pharmacologic treatment for ACC, but further studies are required to characterize different profiles of therapeutic response.

Abstract
RB1 mutations accountable for biallelic inactivation are crucial events in the development of retinoblastoma because a first mutation (M1) predisposes to retinoblastoma while a second mutation (M2) is required for tumor development. Mutational analyses of this gene showed a wide spectrum of genetic alterations (single base substitutions, insertions, or deletions, as well as small and large deletions). The most frequent second hit in retinoblastoma patients is loss of heterozygosity (LOH) followed by promoter methylation. Molecular analyses of RB1 mutations were conducted in 36 patients (20 unilateral and 16 bilateral) using polymerase chain reaction-mediated single-strand conformation polymorphism (SSCP) analysis, sequencing, and LOH analysis. Sixty-four amplified fragments showing abnormal SSCP patterns were sequenced, and mutations were confirmed in five patients (13.89%). Four mutations were located at coding regions, and a fifth one was found at an exon-intron junction. Two mutations were C-->T transitions, two were small-length deletions, and one was a G-->A transition. A total of 47.05% patients showed LOH. In one patient, the parental origin of the mutated allele was detected: the allele retained in the tumor was the paternal one. This work helps to characterize the spectrum of mutations in the Brazilian population, and to confirm that formaldehyde-fixed paraffin tissue can provide valuable information on the RB1 status in retinoblastoma patients.

Abstract
AIMS To carry out a retrospective study, screening for mutations of the entire coding region of RB1 and adjacent intronic regions in patients with retinoblastoma. METHODS Mutation screening in DNA extracts of formalin fixed, paraffin wax embedded tissues of 28 patients using combined "exon by exon" polymerase chain reaction mediated single strand conformational polymorphism analysis, followed by DNA sequencing. RESULTS Eleven mutations were found in 10 patients. Ten mutations consisted of single base substitutions; 10 were localised in exonic regions (eight nonsense, one missense, and one frameshift) and another one in the intron-exon splicing region. Three novel mutations were identified: a 2 bp insertion in exon 2 (g.5506-5507insAG, R73fsX77), a G to A transition affecting the last invariant nucleotide of intron 13 (g.76429G>A), and a T to C transition in exon 20 (g.156795T>C, L688P). In addition, eight C to T transitions, resulting in stop codons, were found in five different CGA codons (g.64348C>T, g.76430C>T, g.78238C>T, g.78250C>T, and g.150037C>T). Although specific mutation hotspots have not been identified in the literature, eight of the 11 mutations occurred in CGA codons and seven fell within the E1A binding domains (codons 393-572 and 646-772), whereas five were of both types-in CGA codons within E1A binding domains. CONCLUSIONS CGA codons and E1A binding domains are apparently more frequent mutational targets and should be initially screened in patients with retinoblastoma. Paraffin wax embedded samples proved to be valuable sources of DNA for retrospective studies, providing useful information for genetic counselling.
