Collaboration for success: the Global Initiative for Childhood Cancer in Latin America.

The Global Initiative for Childhood Cancer (GICC) aims to increase the cure rate for children with cancer globally by improving healthcare access and quality. The Pan American Health Organization (PAHO), St. Jude Children's Research Hospital (St. Jude), and collaborators have joined efforts to improve outcomes of children with cancer in Latin America and the Caribbean (LAC) using the CureAll framework. In this article, we describe the process of developing regional resources aimed at accelerating the GICC implementation in LAC. In March 2021, PAHO formed regional working groups to develop core projects aligned with CureAll pillars and enablers. Seven working groups emerged from regional dialogues: early detection, nursing, psychosocial, nutrition, supportive care, treatment abandonment, and palliative care. PAHO arranged regular online meetings under the mentorship and support of St. Jude regional/transversal programs and international mentors. Between April and December 2021, 202 multidisciplinary experts attended 43 online meetings to promote the dialogue between stakeholders to improve childhood cancer outcomes. Fourteen technical outputs were produced: four regional snapshots, four technical documents, two virtual courses, one set of epidemiological country profiles, one educational content series for parents/caregivers, and two communication campaigns. The ongoing dialogue and commitment of PAHO, St. Jude, LAC working committees, and international collaborators are essential foundations to successfully accelerate GICC implementation. This is achievable through the development of materials of regional and global relevance. Further research and evaluation are needed to determine the impact of these strategies and resources on childhood cancer outcomes in LAC and other regions.

Morphological Harbingers of ARMC5-Pathogenic Variant-Related Bilateral Macronodular Adrenocortical Disease.

Bilateral macronodular adrenocortical disease (BMAD) is a neoplastic disease associated with a high frequency of germline disease. Armadillo repeat containing 5 (ARMC5) pathogenic variants (PVs) have not been widely studied to determine the morphological and immunohistochemical characteristics of BMAD. We carried out a detailed morphologic review of 22 surgical specimens excised from patients with BMAD and compared them with PV of ARMC5 (PV + , n = 14) and those without (PV - , n = 8), and further comparing them with a control group of adrenals excised from patients with renal cancer (n = 11). No patients presented with a genetic syndrome related to BMAD. Overt Cushing's syndrome was present in 12/22 patients, 10 PV + and 2 PV - (p = 0.074). We also evaluated the expression of Ki-67, BCL-2, BAX, p53, CYP11B1, and ARMC5 protein. The pseudo-glandular and trabecular architectural patterns were strongly associated with the PV + group (both p < 0.001), as well as capsular extrusion (p < 0.001). There was no predictive value in the distinction of ARMC5 variants in Hsiao subtyping. ARMC5 diffuse cytoplasmic staining was observed in all 11 control samples. The ARMC5 expression was significantly lower in BMAD than in the control group (p < 0.001). In all the specimens, expression of BCL-2 was identified only in the medulla, and expression of BAX was observed in adrenocortical cells. CYP11B1 diffuse immunoexpression was identified in all the specimens of BMAD and in the fasciculata zone in the control group. The mitotic count and Ki-67 proliferation index was very low in all three groups (controls, PV + , and PV - BMAD). None of the specimens stained positive for the p53 protein. Although our series is limited, the presence of pseudo-glandular and/or trabecular patterns and capsular extrusion indicated the presence of pathogenic variants of ARMC5 in BMAD. The gland enlargement does not seem to be related to the increase of mitotic count or a higher proliferation index (Ki-67).

Sociodemographic Disparities in Presentation and Survival of Pediatric Bone Cancers.

Osteosarcoma (OST) and Ewing sarcoma (ES) are the most common pediatric bone cancers. Patients with metastatic disease at diagnosis have poorer outcomes compared with localized disease. Using the Surveillance, Epidemiology, and End Results registries, we identified children and adolescents diagnosed with OST or ES between 2004 and 2015. We examined whether demographic and socioeconomic disparities were associated with a higher likelihood of metastatic disease at diagnosis and poor survival outcomes. In OST, Hispanic patients and those living in areas of high language isolation were more likely to have metastatic disease at diagnosis. Regardless of metastatic status, OST patients with public insurance had increased odds of death compared to those with private insurance. Living in counties with lower education levels increased odds of death for adolescents with metastatic disease. In ES, non-White adolescents had higher odds of death compared with white patients. Adolescents with metastatic ES living in higher poverty areas had increased odds of death compared with those living in less impoverished areas. Disparities in both diagnostic and survival outcomes based on race, ethnicity, and socioeconomic factors exist in pediatric bone cancers, potentially due to barriers to care and treatment inequities.

Survival analysis of young adults from a Brazilian cohort of non-small cell lung cancer patients.

BACKGROUND: The influence of age at diagnosis in non-small cell lung cancer (NSCLC) prognosis is unclear. OBJECTIVES: To compare in a Brazilian cohort of NSCLC patients of different age groups: 1) The overall survival; 2) Clinical features and treatment options. METHODS: This is a retrospective cohort study using a hospital-based registry, for NSCLC patients registered in years 2000-2009. Patients were grouped into three age groups: Young adults (YA: < 40 years), middle-aged (MA: 40-64 years) and elderly (E: ≥ 65 years). Kaplan-Meier was used to estimate overall survival and Cox regression for hazard ratios (HRs) and 95% confidence intervals. RESULTS: 17,422 NSCLC patients were included: 370 YA (2.1%), 8,697 MA (49.9%) and 8,355 E (48.0%). Compared with older age groups, the YA group had a higher proportion of females, patients diagnosed with adenocarcinoma and metastatic disease (63.2%). Overall survival was longer in YA in the entire cohort and in all clinical stages (CSs) (p < 0.001). For YA, higher education level was a good prognosis factor (compared with illiterate and incomplete elementary); advanced or metastatic disease (compared with early-stage disease) and treatment based in radiotherapy or chemotherapy (CT) (without surgery), compared with treatment combinations with surgery, were poor prognostic factors. Young men (but not women) had lower HR of death compared with older groups; YA had lower HR of death in all CSs compared with patients from older groups. A higher percentage of YA were treated with surgery or CT in early-stage disease compared with older groups. Besides that, YA and MA patients treated with surgery or CT had a better prognosis than elderlies. Conclusions: In this Brazilian cohort of NSCLC patients, most young individuals were diagnosed with metastatic disease. YA presented longer survival than older age groups in all CSs, but mainly in CS I/II and III, where some patients may achieve long remissions or cure.

Childhood cancer mortality trends in the Americas and Australasia: An update to 2017.

BACKGROUND: Marked reductions in childhood cancer mortality occurred over the last decades in high-income countries and, to a lesser degree, in middle-income countries. This study aimed to monitor mortality trends in the Americas and Australasia, focusing on areas showing unsatisfactory trends. METHODS: Age-standardized mortality rates per 100,000 children (aged 0-14 years) from 1990 to 2017 (or the last available calendar year) were computed for all neoplasms and 8 leading childhood cancers in countries from the Americas and Australasia, using data from the World Health Organization database. A joinpoint regression was used to identify changes in slope of mortality trends for all neoplasms, leukemia, and neoplasms of the central nervous system (CNS) for major countries. RESULTS: Over the last decades, childhood cancer mortality continued to decrease by approximately 2% to 3% per year in Australasian countries (ie, Japan, Korea, and Australia), by approximately 1.5% to 2% in North America and Chile, and 1% in Argentina. Other Latin American countries did not show any substantial decrease. Leukemia mortality declined in most countries, whereas less favorable trends were registered for CNS neoplasms, particularly in Latin America. Around 2016, death rates from all neoplasms were 4 to 6 per 100,000 boys and 3 to 4 per 100,000 girls in Latin America, and 2 to 3 per 100,000 boys and approximately 2 per 100,000 girls in North America and Australasia. CONCLUSIONS: Childhood cancer mortality trends declined steadily in North America and Australasia, whereas they were less favorable in most Latin American countries. Priority must be given to closing the gap by providing high-quality care for all children with cancer worldwide. LAY SUMMARY: Advances in childhood cancer management have substantially improved the burden of these neoplasms over the past 40 years, particularly in high-income countries. This study aimed to monitor recent trends in America and Australasia using mortality data from the World Health Organization. Trends in childhood cancer mortality continued to decline in high-income countries by approximately 2% to 3% per year in Japan, Korea, and Australia, and 1% to 2% in North America. Only a few Latin American countries showed favorable trends, including Argentina, Chile, and Mexico, whereas other countries with limited resources still lagged behind.

Childhood cancer in Latin America: from detection to palliative care and survivorship.

BACKGROUND: Treatment options for childhood cancer have improved substantially, although in many low- and middle-income countries survival is lagging behind. Integral childhood cancer care involves the whole spectrum from detection and diagnosis to palliative and survivorship care. METHODS: Based on a literature review and expert opinions, we summarized current practice and recommendations on the following aspects of childhood cancer in Latin America: diagnostic processes and time to diagnosis, stage at diagnosis, treatments and complications, survivorship programs and palliative care and end-of-life services. RESULTS: Latin America is a huge and heterogeneous continent. Identified barriers show similar problems between countries, both logistically (time and distance to centers, treatment interruptions) and financially (cost of care, cost of absence from work). Governmental actions in several countries improved the survival of children with cancer, but difficulties persist in timely diagnosis and providing adequate treatment to all childhood cancer patients in institutions with complete infrastructure. Treatment abandonment is still common, although the situation is improving. Cancer care in the region has mostly focused on acute treatment of the disease and has not adequately considered palliative and end-of-life care and monitoring of survivors. CONCLUSIONS: Decentralizing diagnostic activities and centralizing specialized treatment will remain necessary; measures to facilitate logistics and costs of transportation of the child and caretakers should be implemented. Twinning actions with specialized centers in high income countries for help in diagnosis, treatment and education of professionals and family members have been shown to work. Palliative and end-of-life care as well as childhood cancer survivorship plans are needed.

Trends in prostate cancer mortality in the state of São Paulo, 2000 to 2015.

OBJECTIVE To estimate the magnitude and identify patterns of change in prostate cancer mortality in the state of São Paulo and in the 17 regional health care networks, according to age groups from 50 years onwards, in the period between 2000 to 2015. METHODS Age-adjusted mortality rates (per 100,000 men) were calculated by the direct method using the Segi world population as standard. Joinpoint regression was used to calculate the average annual percent change (AAPC), with a confidence interval of 95% (95%CI), by regional network and age group (50-59, 60-69, 70-79 and 80 years or more). RESULTS For the state of São Paulo, age-adjusted mortality rates were 15.2, 13.3 and 11.9 per 100,000 men, respectively, in the periods between 2000 to 2005, 2006 to 2010 and 2011 to 2015, with a significant decrease trend (AAPC = -2.10%; 95%CI -2.42 - -1.79) each year. Among the 17 networks, 11 presented significant mean annual reductions, ranging from -1.72% to -3.05%. From the age of 50 onwards, there was a sharper reduction in the groups from 50 to 59 (AAPC = -2.33%; 95%CI -3.04 - -1.62) and 60 to 69 years (AAPC = -2.84%; 95%CI - 3.25 - -2.43). CONCLUSION Although reductions in mortality are still slight, they indicate progress in prostate cancer control actions. Screening actions and changes in therapeutic behaviors in recent decades may be modifying incidence and survival, resulting in changes in the mortality profile. More detailed studies will be useful in understanding the factors that lead to the interregional variations found.

Trends in prostate cancer mortality in the state of São Paulo, 2000 to 2015 / Tendências na mortalidade por câncer de próstata no estado de São Paulo, 2000 a 2015

RESUMO OBJETIVO Estimar a magnitude e identificar padrões de mudança na mortalidade por câncer de próstata no estado de São Paulo e nas 17 redes regionais de atenção à saúde, segundo grupos etários a partir dos 50 anos, no período de 2000 a 2015. MÉTODOS As taxas de mortalidade ajustadas por idade (por 100 mil homens) foram calculadas pelo método direto usando a população mundial de Segi como padrão. A análise de regressão Joinpoint foi utilizada para calcular as variações percentuais anuais médias (AAPC), com intervalo de confiança de 95% (IC95%), por rede regional e grupo etário (50-59, 60-69, 70-79 e 80 anos ou mais). RESULTADOS Para o estado de São Paulo, as taxas ajustadas de mortalidade foram de 15,2, 13,3 e 11,9/100 mil homens, respectivamente, nos períodos de 2000 a 2005, 2006 a 2010 e 2011 a 2015, com tendência de decréscimo significativo (AAPC = -2,10%; IC95% -2,42 - -1,79) a cada ano. Das 17 redes, 11 apresentaram reduções médias anuais significativas, que variaram entre -1,72% e -3,05%. A partir dos 50 anos, verificou-se redução mais acentuada nos grupos de 50 a 59 (AAPC = -2,33%; IC95% -3,04 - -1,62) e 60 a 69 anos (AAPC = -2,84%; IC95% -3,25 - -2,43). CONCLUSÕES Embora as reduções na mortalidade ainda sejam discretas, indicam progresso nas ações de controle do câncer de próstata. Ações de rastreamento e mudanças nas condutas terapêuticas nas últimas décadas podem estar modificando a incidência e a sobrevida, resultando em mudanças no perfil de mortalidade. Estudos mais detalhados serão úteis na compreensão dos fatores que levam às variações inter-regionais encontradas.

Use of a low-cost telecytopathology method for remote assessment of thyroid FNAs.

BACKGROUND: Rapid on-site evaluation is a great tool for optimizing the adequacy and quality of cytologic samples. The objective of the current study was to analyze a low-cost telecytopathology method for the remote assessment of thyroid fine-needle aspiration biopsies (FNABs), with comparison of the primarily rendered adequacy and diagnosis with the final conventional analysis. METHODS: Material collected from thyroid FNABs was immediately smeared onto glass slides and stained with Diff-Quik. A conventional microscope attached to a smart device was operated on-site by either a medical student or a pathology resident for Wi-Fi transmission of the images by Skype. The cytopathologist would remotely guide the screening of the slides, zooming in and out of areas of interest. Remote assessment included an analysis of material adequacy and a preliminary diagnosis. The quality of the transmission and the number of slides also were recorded. After a washout period of 3 weeks, final diagnosis and adequacy were assigned by conventional microscopy. RESULTS: The final agreement rate for adequacy between remote and conventional analysis was 90.5%. For diagnosis, the final agreement rate was 83.3%. The diagnosis agreement rate varied, depending on the quality of transmission: there was 88% agreement when the quality was excellent, 77.8% agreement when it was good, and 62.5% agreement when it was poor. CONCLUSIONS: Low-cost telecytopathology is an efficient method for the remote assessment of thyroid FNAB adequacy and diagnosis. The wide use of such technology in low-resource or remote centers may have a positive impact on the number of adequate or satisfactory samples, optimizing the management of patients who have thyroid nodules.

Older adults with cancer in the city of São Paulo: what factors determine the place of death?

OBJECTIVE: Investigate factors associated with death at home among older adults who died of cancer in a large city. METHODS: This is a descriptive study, including all cancer deaths (ICD C00-C97) occurring between 2006 and 2012, among residents of the city of São Paulo, 60 years of age or older. The data source was the Mortality Information System, and the proportion of deaths was calculated according to place of occurrence, gender, age, race/skin color, education, marital status, cancer type, hospital bed availability, and year of death. The chi-squared test was used to examine the associations between the place of death and sociodemographic and clinical variables. Logistic regression was used to identify factors associated with home death. Crude and adjusted odds ratios and the corresponding 95% confidence intervals were estimated. RESULTS: Most of the deaths occurred in hospitals (88.2%). There was a significant association between the place of death and the following variables: gender, race/skin color, education, age, marital status, cancer type, hospital bed availability, and year of death. In the multivariate analysis, all variables, except the availability of hospital beds, remained as independent predictors of death at home. CONCLUSIONS: There was a predominance of hospital deaths, with an increase in frequency in the period. Female gender, higher education, married or widowed status, and black race were associated with a decreased risk of death at home, while increasing age, Asian race, and solid neoplasms were associated with higher risk of dying at home.

Frequency of EBV associated classical Hodgkin lymphoma decreases over a 54-year period in a Brazilian population.

The epidemiology of classical Hodgkin lymphoma varies significantly in populations with different socioeconomic conditions. Among other changes, improvement in such conditions leads to a reduction in the association with EBV infection and predominance of the nodular sclerosis subtype. This study provides an overview of the epidemiology of 817 cases of classical Hodgkin lymphoma diagnosed in five reference hospitals of the State of Sao Paulo, Brazil, over 54 years (1954-2008). The cases were distributed in 3 periods (1954-1979; 1980-1999; and 2000-2008). EBV-positive cases decreased from 87% to 46%. In children and adolescents (<15 years) and in young adults (15-45 years), EBV-positive cases decreased respectively from 96% to 64%, and from 85% to 32%. The percentage of male patients declined from 80% to 58%. In older patients (>45 years), the decrease in EBV infection was not significant. Nodular Sclerosis was the most common subtype in all periods. These results support the hypothesis that, in the Brazilian State of Sao Paulo, classical Hodgkin lymphoma has changed and now shows characteristics consistent with Pattern III observed in populations that experienced a similar socioeconomic transition.

RESUMO OBJETIVO Investigar os fatores associados ao óbito domiciliar entre idosos que morreram por câncer em uma cidade de grande porte. MÉTODOS Estudo descritivo, incluindo todos os óbitos por câncer (CID C00-C97) ocorridos entre 2006 e 2012, entre residentes do município de São Paulo com 60 anos de idade ou mais. A fonte de dados foi o Sistema de Informações de Mortalidade e a proporção de óbitos foi estimada segundo local, sexo, faixa etária, raça/cor, escolaridade, estado civil, tipo de câncer, disponibilidade de leitos hospitalares e ano do óbito. O teste qui-quadrado foi utilizado para investigar as associações entre o local do óbito e as variáveis sociodemográficas e clínicas. A regressão logística foi empregada para identificar fatores associados à morte domiciliar. Foram estimadas as razões de chance brutas e ajustadas e os intervalos de confiança de 95%. RESULTADOS A maioria dos óbitos ocorreu em hospitais (88,2%). Houve associação significativa entre o local de óbito e as seguintes variáveis: sexo, raça/cor, escolaridade, faixa etária, estado civil, tipo de câncer, disponibilidade de leitos hospitalares e ano do óbito. Na análise multivariada, todas as variáveis, exceto a disponibilidade de leitos hospitalares, permaneceram como preditores independentes de óbito domiciliar. CONCLUSÕES Houve predomínio de óbitos hospitalares, com aumento na frequência no período. O sexo feminino, maior escolaridade, o status de casado ou viúvo e a raça negra foram associados à menor chance de óbito domiciliar, enquanto o aumento da idade, a raça/cor amarela e as neoplasias sólidas estiveram associados à maior chance de morrer em casa.

Death Within 1 Month of Diagnosis in Childhood Cancer: An Analysis of Risk Factors and Scope of the Problem.

Purpose Despite advances in childhood cancer care, some patients die soon after diagnosis. This population is not well described and may be under-reported. Better understanding of risk factors for early death and scope of the problem could lead to prevention of these occurrences and thus better survival rates in childhood cancer. Methods We retrieved data from SEER 13 registries on 36,337 patients age 0 to 19 years diagnosed with cancer between 1992 and 2011. Early death was defined as death within 1 month of diagnosis. Socioeconomic status data for each individual's county of residence were derived from Census 2000. Crude and adjusted odds ratios and corresponding 95% CIs were estimated for the association between early death and demographic, clinical, and socioeconomic factors. Results Percentage of early death in the period was 1.5% (n = 555). Children with acute myeloid leukemia, infant acute lymphoblastic leukemia, hepatoblastoma, and malignant brain tumors had the highest risk of early death. On multivariable analysis, an age younger than 1 year was a strong predictor of early death in all disease groups examined. Black race and Hispanic ethnicity were both risk factors for early death in multiple disease groups. Residence in counties with lower than median average income was associated with a higher risk of early death in hematologic malignancies. Percentages of early death decreased significantly over time, especially in hematologic malignancies. Conclusion Risk factors for early death in childhood cancer include an age younger than 1 year, specific diagnoses, minority race and ethnicity, and disadvantaged socioeconomic status. The population-based disease-specific percentages of early death were uniformly higher than those reported in cooperative clinical trials, suggesting that early death is under-reported in the medical literature. Initiatives to identify those at risk and develop preventive interventions should be prioritized.

Use of cytology as an auxiliary diagnostic tool in autopsies.

BACKGROUND: The use of minimally invasive procedures in autopsies such as image-guided fine-needle aspiration may facilitate family acceptance and, therefore, increase the number of postmortem examinations. The objective of the current study was to validate the use of cytology in a prospective set of conventional autopsies. METHODS: All lesions and organs sampled for histological examination were concomitantly evaluated by scrape cytology of exactly the same location. The cytopathologist and the surgical pathologist were blinded to each other's microscopic findings. Final cytological and histological diagnoses were divided into 6 main diagnostic groups: normal, neoplasms (benign and malignant), inflammatory conditions, adaptive processes, degeneration, and cardiovascular disorders. Cytohistological agreement was assessed with Cohen's κ coefficient. The simple percentage agreement was also reported for each diagnostic group and for all different organs sampled in the postmortem examinations. RESULTS: Two hundred eleven samples were studied from 36 consecutive autopsies (21 males and 15 females; median age, 58 years). Complete cytohistological agreement was achieved for 151 samples (71.6%) with a κ coefficient of 0.43 (moderate correlation). When samples were divided by diagnostic group, the best results were seen in normal specimens (93.8%) and neoplasms (82.3%). Organs with the best performance included the thyroid, cerebellum, lymph nodes, and adrenal glands (all with 100% agreement), the brain (90.5%), and the pancreas (84.6%). CONCLUSIONS: Cytology showed a good correlation with histology, particularly for neoplastic cases and specimens with minimal pathological alterations, and could be used as an alternative diagnostic method in partial or restricted postmortem examinations.

An Increased Risk of Second Malignant Neoplasms After Rhabdomyosarcoma: Population-Based Evidence for a Cancer Predisposition Syndrome?

BACKGROUND: Rhabdomyosarcoma survivors have an increased risk of developing second malignant neoplasms (SMN); this risk is traditionally attributed to the effects of multidisciplinary management required for cure. However, the impact of constitutional predisposition has not been properly analyzed. METHODS: We analyzed the risk of SMN among 1,151 children diagnosed with rhabdomyosarcoma and reported to the Surveillance, Epidemiology, and End Results registries (SEER-9) from 1973 to 2010. Standardized incidence ratios (SIR) and corresponding 95% confidence intervals (CI) were calculated using SEERStat 8.1.2. RESULTS: Children with pleomorphic and embryonal rhabdomyosarcoma had an increased risk of developing a SMN (SIR = 15.77, 95%CI 1.91-56.96 and SIR = 5.6, 95%CI 3.32-8.85, respectively). The risk was age-dependent; the highest was among children <2 years (SIR = 13.38, 95%CI 4.34-31.22) and the lowest was in children >10 years (SIR = 3.35, 95%CI 1.53-6.35). The risk for the youngest patients was higher for those with embryonal rhabdomyosarcoma (SIR = 14.72, 95%CI 4.01-37.70) compared to other histiotypes. Additionally, the risk of SMN was independent of the use of radiation to the primary (SIR = 6.50, 95%CI 3.97-10.03 and SIR = 4.57, 95%CI 2.09-8.68, for children receiving and not receiving radiation, respectively). The pattern of SMN observed was consistent with the Li-Fraumeni spectrum. CONCLUSIONS: Children with rhabdomyosarcoma are at high risk of developing SMN. This risk is higher for a subgroup of young children with pleomorphic and embryonal histologies, and is independent of the use of radiation. This suggests that a subgroup of children with pleomorphic and embryonal rhabdomyosarcoma may have a constitutional cancer predisposition.

Ethnicity, race, and socioeconomic status influence incidence of Langerhans cell histiocytosis.

BACKGROUND: Langerhans cell histiocytosis (LCH) is a rare disease, and its etiology is not well understood. Population-based studies may contribute to etiologic research by defining incidence patterns. This study was designed to evaluate the descriptive epidemiology of disseminated LCH in the United States, using data from population-based cancer registries. PROCEDURE: We analyzed the incidence and survival of disseminated LCH in children and adolescents (0-19 years) from 18 SEER registries during 2000-2009. Age-standardized incidence rates (ASIR) per million and rate ratios (RR) were calculated by gender, race, ethnicity, age, and socioeconomic variables (crowding, rural/urban, education, and poverty) using the SEER*Stat software 8.0.1. Relative survival (RS) estimates were calculated using Ederer II method. RESULTS: One hundred forty-five cases of disseminated LCH were recorded; ASIR was 0.70/million per year. Lower ASIR was observed for blacks (vs. whites) (RR = 0.41, 95% CI 0.18-0.81), while higher ASIR was noted for Hispanics (vs. non-Hispanics) (RR = 1.63, 95% CI 1.15-2.29). Risk of LCH was higher in crowded counties (RR = 1.84, 95% CI 1.31-2.58) and also in areas with low educational level (RR = 1.49, 95% CI 1.02-2.22). Five-year relative survival was 90.0% (95% CI 83.0-94.2). Important differences in survival were noted according to gender (male: RS = 96.0 vs. female: RS = 83.4%, P = 0.029) and age (<1 year: RS = 78.5, 1-4 years: RS = 95.6%, 5-19 years: RS = 100%, P = 0.004). CONCLUSIONS: This population-based study shows significant variations in the incidence of disseminated LCH by race and ethnic group, as well as the influence of socioeconomic factors. These data may provide clues to causation and point toward the need for analytical epidemiologic studies.

Tendências na incidência e mortalidade por acidentes de trabalho no Brasil, 1998 a 2008 / Trends in incidence and mortality due to occupational accidents in Brazil, 1998-2008 / Tendencias en la incidencia y la mortalidad por accidentes de trabajo en Brasil, 1998-2008

O objetivo do estudo foi avaliar as tendências na incidência e mortalidade por acidentes de trabalho no Brasil, de 1998 a 2008. Trata-se de estudo ecológico de séries temporais, que incluiu, para a análise, os acidentes de trabalho registrados nas estatísticas oficiais do Governo Federal. Foram calculadas as variações percentuais anuais (APC) nas taxas de incidência e de mortalidade, através da modelagem pelo método Joinpoint, usando o ano calendário como variável regressora. Observou-se tendência significativa de decréscimo na taxa de incidência de acidentes de trabalho, o mesmo ocorrendo para os acidentes de trabalho típicos. Para ambos, o número de casos aumentou nesse período. O número de casos de acidentes de trabalho de trajeto e sua incidência mostraram tendência significativa de aumento. O número de óbitos e a taxa de mortalidade registraram tendência de decréscimo. São discutidos como fatores contribuintes para o declínio das taxas de incidência de acidentes de trabalho e de mortalidade por esta causa: melhoria das condições de trabalho, maior crescimento do setor de serviços do que do setor industrial, subnotificação dos acidentes de trabalho e terceirização dos serviços. O aumento dos acidentes de trabalho de trajeto sugere a influência da violência dos centros urbanos.

The objective was to evaluate trends in incidence and mortality due to occupational accidents in Brazil from 1998 to 2008. This was a time-trend series study that included cases of occupational accidents recorded in official Federal government statistics. The authors calculated annual percentage changes (APC) in incidence and mortality rates with the Joinpoint method using the calendar year as a regressor variable. There was a significant downward trend in incidence rates of occupational accidents, and the same trend was observed in typical occupational accidents. However, the number of cases increased during this period. There was a statistically significant upward trend in the incidence and number of cases of commuting accidents. The number of deaths and mortality rates showed a downward trend. Several factors may have contributed to the decline in incidence and mortality rates for occupational accidents, including improvement in working conditions, a shift in the economy from industry to services, underreporting of occupational accidents, and outsourcing of services. The increase in commuting accidents suggests the influence of violence in urban areas.

El objetivo fue evaluar las tendencias en la incidencia y la mortalidad por accidentes de trabajo en Brasil, de 1998 a 2008. Se trata de un estudio ecológico de series temporales que incluyó el análisis de los accidentes de trabajo registrados en las estadísticas oficiales del Gobierno Federal. Se calculó el cambio porcentual anual en las tasas de incidencia y en las tasas de mortalidad por el método Joinpoint, utilizando el año natural como variable regresora. Hubo una tendencia significativa de disminución de las tasas de incidencia por accidentes de trabajo, lo mismo sucedió con los accidentes de trabajo típicos. Sin embargo, el número de casos ha aumentado. El número de casos de accidentes de trabajo de desplazamiento y sus tasas de incidencia mostró una tendencia en aumento. El número de muertes y tasas de mortalidad mostró una tendencia decreciente. Se discuten los factores que contribuyen a la disminución de tasas de incidencia y tasas de mortalidad por accidentes de trabajo: la mejora de las condiciones de trabajo, un mayor crecimiento del sector de servicios, en relación con el sector industrial, el subregistro de accidentes de trabajo, y servicios de outsourcing. El aumento de accidentes de trabajo durante el desplazamiento sugiere la influencia de la violencia en los centros urbanos.

Increase in the incidence of differentiated thyroid carcinoma in children, adolescents, and young adults: a population-based study.

OBJECTIVE: To investigate trends in incidence of differentiated thyroid carcinomas among children and adolescents and young adults. STUDY DESIGN: In this ecological time-trends study, we selected cases of differentiated thyroid carcinomas (1984-2010) in patients <30 years from Surveillance, Epidemiology, and End Results 9 cancer registries by using International Classification of Diseases for Oncology, 3rd edition, codes for papillary and follicular cancers. Patients with multiple other primary diseases before differentiated thyroid carcinomas were excluded. SEER*Stat software, version 8.0.4 (National Cancer Institute, Bethesda, Maryland) was used to calculate age-standardized rates (estimated per 1,000,000/persons) and annual percentage changes (APCs) were calculated by the Joinpoint model (Joinpoint software, version 4.0.4; National Cancer Institute). RESULTS: Rates ranged from 2.77 (1990) to 9.63 (2009) and from 18.35 (1987) to 50.99 (2009), for male and female subjects, respectively. A significant increasing trend in incidence was observed for both male (APC 3.44; 95% CI 2.60-4.28) and female (APC 3.81; 95% CI 3.38-4.24) patients. When a stratified analysis on the basis of tumor size was performed, significant increasing trends were noted for the following categories: <0.5 cm (females: APC 5.09, 95% CI 3.54-6.65), 0.5-0.9 cm (females: APC 8.45, 95% CI 7.09-9.82), 1.0-1.9 cm (males: APC 5.09, 95% CI 3.20-7.01; females: APC 3.42, 95% CI 2.78-4.07), and ≥2 cm (males: APC 2.62, 95% CI 1.64-3.60; females: APC 2.96, 95% CI 2.34-3.59). CONCLUSIONS: Incidence rates for differentiated thyroid carcinomas are increasing among children and adolescents and young adults in the US. The increasing trends for larger tumors rules out diagnostic scrutiny as the only explanation for the observed results. Environmental, dietary, and genetic influences should be investigated.

Bevacizumab as first-line therapy in advanced non-small-cell lung cancer: a brazilian center experience.

OBJECTIVES: Bevacizumab has been approved by the US Food and Drug Administration as a first-line therapy for metastatic non-small-cell lung cancer (NSCLC), in combination with carboplatin and paclitaxel. A single Latin American center experience was reviewed to determine the safety and efficacy of adding bevacizumab to first-line chemotherapy in a local population. METHODS: We retrospectively identified patients with non-squamous NSCLC treated with bevacizumab plus chemotherapy combinations as first-line chemotherapy between July 1, 2006, and January 30, 2011, at Sirio Libanes Hospital in Sao Paulo, Brazil. We collected data on patient characteristics, treatment combinations, toxicities, response to treatment, and survival. Overall survival (OS) and progression-free survival (PFS) were calculated by Kaplan-Meier analysis, and prognostic factors were identified by the Cox regression model. RESULTS: A total of 56 patients were included in the final analysis (median age 62.4 years; 70% male). In 35 patients (62.5%), bevacizumab was combined with carboplatin and paclitaxel, and in 16 patients (28.6%), it was combined with pemetrexed and carboplatin. The response rate evaluated by the reference clinical team reached 74.5%, the median PFS was 5.3 months, and the median OS was 14.8 months. In multivariate analysis, use of maintenance therapy was the only predictive factor for OS (hazard ratio 6.85, 95% confidence interval 2.94-15.22). No treatment-related deaths were identified, and the overall incidence of grade 3-4 non-hematologic toxicities was 16%. CONCLUSION: Our results confirm the efficacy and safety data of bevacizumab first-line combinations for NSCLC in a Brazilian population.
