Article Synopsis
- Retinoblastoma is the most common eye cancer in children, and challenges in diagnosis and treatment remain, especially in low- and middle-income countries.
- A systematic review identified 21 studies focused on strategies like surveillance, genetic counseling, education, public assistance, and international partnerships that can improve diagnosis and treatment access.
- Proposed initiatives from the review aim to enhance clinical outcomes for retinoblastoma patients, emphasizing the need for systematic implementation of these strategies.
Purpose: There is a paucity of studies investigating cancer disparities in groups defined by ethnicity in transitioning economies. We examined the influence of ethnicity on mortality for the leading cancer types in São Paulo, Brazil, comparing patterns in the capital and the northeast of the state.
Methods: Cancer deaths were obtained from a Brazilian public government database for the Barretos region (2003-2017) and the municipality of São Paulo (2001-2015).
Background: This study examined the spatial pattern of the colorectal cancer (CRC) in the 18 municipalities that compose the Regional Health Department of Barretos (RHD-V), which is in the northeast of the state of São Paulo, Brazil.
Methods: All incident cases and deaths from CRC between 2002 and 2016 were included. Age-standardized rates (ASR) for incidence and mortality per 100,000 person-years were used to evaluate the spatial distribution for the total and five-year periods.
Article Synopsis
- Thyroid cancer cases are rising, particularly due to better detection of less aggressive tumors; the study explores the correlation between thyroid cancer incidence and mortality rates across different socioeconomic status (SES) groups in São Paulo.
- Data was collected from cancer registries and death records, revealing that São Paulo had significantly higher thyroid cancer cases and incidences than Barretos, with a notable trend showing higher incidence rates in higher SES areas in São Paulo.
- The results suggest that as SES increases, so does the incidence of thyroid cancer, indicating that overdiagnosis could be contributing to the high rates observed, especially in São Paulo.
Article Synopsis
- Cancer is a major health issue in Brazil, with increasing incidence and mortality rates, analyzed by small geographic areas in São Paulo.
- The study utilized cancer registries and government data from 2001 to 2017, presenting age-standardized cancer rates through thematic maps.
- Key findings indicate that prostate and breast cancers have high incidence rates in Barretos, while lung cancer shows the highest mortality in both regions, with SES influencing the cancer profiles significantly.
Background: Cancer disparities exist between and within countries; we sought to compare cancer-specific incidence and mortality according to area-level socioeconomic status (SES) in the State of São Paulo, Brazil.
Methods: Cancer cases diagnosed 2003-2017 in the Barretos region and 2001-2015 in the municipality of São Paulo were obtained from the respective cancer registries. Corresponding cancer deaths were obtained from a Brazilian public government database.
Intra-urban spatial variability of breast and cervical cancer mortality in the city of São Paulo: analysis of associated factors.
Rev Bras Epidemiol
January 2023
Objective: To identify spatial variability of mortality from breast and cervical cancer and to assess factors associated in the city of São Paulo.
Methods: Between 2009 and 2016, 10,124 deaths from breast cancer and 2,116 deaths from cervical cancer were recorded in the Mortality Information System among women aged 20 years and over. The records were geocoded by address of residence and grouped according to Primary Health Care coverage areas.
Objective: To perform a bibliometric analysis of studies that evaluated the barriers to access to cancer palliative care (PC).
Methods: This was a bibliometric review using MEDLINE; EMBASE; Web Of Science; LILACS and the Cochrane Library. A search was conducted with the terms Barriers, Palliative Care and Cancer.
Breast cancer is the most frequently diagnosed type of cancer and is the leading cause of death from cancer in the female population. Screening mammograms and early treatment are the most frequently used means to attempt to reduce this mortality and are promoted during Pink October, an annual awareness-raising campaign. However, recent studies have correlated the increase in screening with higher morbidity and mortality, due to overdiagnosis and overtreatment.

In Brazil, the number of cancer cases for the several next years (2020-2022) is expected to increase up to 625,000. Thus, translational research has been vital to determine the potential risk, prognostic, and predictive biomarkers in cancer.

Cancer Epidemiol Biomarkers Prev
September 2021
Background: Tobacco or human papillomavirus (HPV)-related oropharyngeal squamous cell carcinomas (OPSCC) represent different clinical and epidemiologic entities. This study investigated the prevalence of HPV-positive and HPV-negative OPSCC in a reference cancer hospital in Brazil and its association with clinical and demographic data, as well as its impact on overall survival.
Methods: HPV infection was determined by p16-IHC in pre-treatment formalin-fixed paraffin-embedded samples from all patients with OPSCC diagnosed at Barretos Cancer Hospital between 2008 and 2018.
Objective: To verify the spatial pattern of mortality from breast and cervical cancer in areas of primary health care, considering socioeconomic conditions.
Methods: This is an ecological study, from January 2000 to December 2016. The study area is the municipality of São Paulo, Brazil, and its 456 coverage areas of primary health units.
Background: Despite widespread evidence that air pollution is carcinogenic, there is little evidence from low-middle income countries, especially related to childhood malignancies. We examined the role of traffic related pollution on lymphohematopoietic malignancies among under-14 s in Sao Paulo.
Methods: All incident cases between 2002 and 2011 were collected from a population-based registry.
Traffic-related air pollution is being associated with hematologic cancer in young individuals. This study performed a spatial analysis of the hematologic cancer incidence and mortality among younger people, using a Bayesian approach, to associate with traffic density in the city of São Paulo, Brazil. Two databases were employed: incidence (2002-2011) and mortality (2002-2013).
View Article and Find Full Text PDFPollution related to traffic is a major problem in urban centers and a large portion of the population is vulnerable to its health effects. This study sought to identify a potential association between hospital admissions due to respiratory tract cancer and vehicular traffic density in the city of São Paulo, Brazil. It is an ecological study of the public (Hospital Inpatient Authorization - AIH, in Portuguese) and private (Hospital Inpatient Communication - CIH, in Portuguese) health care systems, from 2004 to 2006, geocoded by individuals' residential addresses.
View Article and Find Full Text PDFBackground: Multiple lines of evidence have associated exposure to ambient air pollution with an increased risk of respiratory malignancies. However, there is a dearth of evidence from low-middle income countries, including those within South America, where the social inequalities are more marked.
Objectives: To quantify the association between exposures to traffic related air pollution and respiratory cancer incidence and mortality within São Paulo, Brazil.
Geography of Microcephaly in the Zika Era: A Study of Newborn Distribution and Socio-environmental Indicators in Recife, Brazil, 2015-2016.
Public Health Rep
