Regional disparities of prostate cancer mortality in Ecuador: an examination of trends and correlates from 2004 to 2019

BACKGROUND

Prostate cancer is the leading cause of cancer death in Ecuadorian men. However, there is a lack of information regarding the evolution of prostate cancer mortality rates in Ecuador and its regions in the last few decades.

OBJECTIVE

The aim of this study was to report prostate cancer mortality rates in Ecuador and its geographical areas and observe the evolution of these rates between 2004 and 2019.

METHODS

An observational ecological study was conducted, analysing data for prostate cancer deaths from 2004 to 2019 in Ecuador. Age standardized mortality rates (ASMR) were calculated per 100,000 men using the world standard population with the direct method proposed by SEGI. Joinpoint regression analysis was performed to examine mortality trends. We used a Cluster Map to explore relationships among regions between 2015 and 2019.

RESULTS

Ecuador reported 13,419 deaths by prostate cancer between 2004 and 2019, with the Coastal region accounting for 49.8% of the total deaths. The mean age at death was 79 years (± 10 years), 91.7% were elderly (more than 65 years old) and had primary education (53%). Deaths by prostate cancer were more frequently reported among mestizos (81.4%). There were no significant variations in these percentages in Ecuador and its regions during the study period. Carchi province had the highest mortality rate in 2005 and 2019 (> 13 deaths per 100,000). Heterogeneity in the evolution of mortality rates was reported among the provinces of Ecuador. Azuay decreased in the first few years, and then increased from 2010 to 2019, whereas Guayas and Pichincha decreased throughout the whole period.

CONCLUSION

Although prostate cancer mortality rates in Ecuador have remained stable over the past few decades, there are significant disparities among the different regions. These findings suggest the need for the development of national and provincial registration measures, integrated healthcare actions, and targeted interventions to reduce the burden of prostate cancer in the Ecuadorian population.

Validated quantitative needs assessment differences in the management of children with central nervous system cancer between Brazil, an upper middle-income country, and the United States of America, a high income country

BACKGROUND

Pediatric cancer cure rates differ among high-income countries (HIC) and upper middle-income countries (UMIC). We have compared individual capacities of two major referral pediatric centers from a HIC and an UMIC caring for children with central nervous system (CNS) cancer.

METHODS

A quantitative needs assessment questionnaire and key informant interviews, distributed in March of 2017, were used to evaluate the treatment of children with CNS cancer at Grupo de Apoio ao Adolescente e à Criança com Câncer (GRAACC) children's cancer center in São Paulo, Brazil and Nationwide Children's Hospital (NCH) in Columbus, Ohio, United States of America (USA).

RESULTS

Both hospitals had 24-hour pediatric oncology, nursing and intensivist coverage. Supportive care available at both institutions included social workers, psychologists, child life specialists, and physical/occupational/speech therapists. Differences included two part-time neuroradiologists and one pathologist specializing in neuropathology at IOP/GRAACC/UNIFESP, whereas eight full-time neuroradiologists and two neuropathologists at NCH/OSU. There were four pediatric neurosurgeons on staff at each hospital; however, there were only 2 operative days per week at IOP/GRAACC/UNIFESP, compared with 7 days at NCH/OSU. Additionally, time to initiation of radiation therapy at IOP/GRAACC/UNIFESP extended 2-4 weeks compared with less than 1 week at NCH/OSU.

CONCLUSIONS

Center-specific differences in resources exist in highly specialized hospitals caring for children with CNS cancer in HIC and UMIC. This quantitative needs assessment may facilitate the development of targeted strategies for effective interventions to improve on the management of children with CNS cancers.

Tamizaje masivo: una revisión de la literatura sociológica

RESUMEN Se provee una revisión de la literatura sociológica a partir de 79 obras referentes a cribados de cáncer y se excluyeron los cribados genéticos prenatal y neonatal. El tamizaje implica el monitoreo de poblaciones aparentemente sanas para rastrear una determinada condición. El rastreo invirtió la concepción tradicional de comprensión sobre las enfermedades al disminuir los umbrales de definición de enfermedad y rompió con la distinción médica tradicional entre enfermos y sanos. A partir de entonces, la práctica clínica comenzó a buscar enfermedades en personas asintomáticas, y así también modificó los comportamientos de los pacientes, que pasaron a ser responsables del cuidado de sí mismos.

Advancing Reliable Data for Cancer Control in the Central America Four Region

The Central America Four (CA-4) region, comprising Guatemala, Honduras, El Salvador, and Nicaragua, is the largest low- and middle-income country region in the Western Hemisphere, with over 36 million inhabitants. The CA-4 nations share a common geography, history, language, and development indices, and unified with open borders in 2006. The growing CA-4 cancer burden among the noncommunicable diseases is expected to increase 73% by 2030, which argues for a regional approach to cancer control. This has driven efforts to establish population-based cancer registries as a central component of the cancer control plans. The involvement of international and academic partners in an array of initiatives to improve cancer information and control in the CA-4 has accelerated over the past several years. Existing data underscore that the infectious cancers (cervical, stomach, and liver) are a particular burden. All four countries have committed to establishing regional population-based cancer registries and have advanced significantly in pediatric cancer registration. The challenges common to each nation include the lack of national cancer control plans and departments, competing health priorities, lack of trained personnel, and sustainability strategies. General recommendations to address these challenges are outlined. The ongoing regional, international, and academic cooperation has proven helpful and is expected to continue to be a powerful instrument to contribute to the design and implementation of long-term national cancer control plans.

Patterns of cervical cancer care in Argentina: Applying ASCO recommendations adjusted by local resources

There are significant differences in cervical cancer incidence and mortality between low-middle and high-income countries. The American Society of Clinical Oncology (ASCO) resource-stratified clinical practice guideline was designed to provide an appropriate cervical cancer treatment based on the best available evidence in scenarios with different diagnostic and therapeutic resources. Argentina, a Latin American high middle income country, shows however, that cervical cancer rates are similar to those of low-income countries. In addition, significant disparities in incidence and mortality are described throughout the country. The present article describes the current pattern of care of cervical cancer in Argentina and establishes recommendations adjusted to local resources in different regions of the country according to the ASCO guideline.

Cancer registration for cancer control in Latin America: a status and progress report

Cancer incidence by type has been included as a core indicator in the World Health Organization (WHO) Global Monitoring Framework for the Prevention and Control of Noncommunicable Diseases. The Global Initiative for Cancer Registry Development (GICR), coordinated by the International Agency for Research on Cancer (IARC), supports low- and middle-income countries to reduce disparities in cancer information for cancer control by increasing the coverage and quality of cancer registration. A baseline assessment has been performed at the IARC Regional Hub for Latin America using secondary and public information sources. Countries have been categorized according to the following criteria for population-based cancer registries (PBCRs): 1) "has no established PBCR (but some registration activity)," 2) "has established PBCR(s) but none of high-quality," and 3) "has established, high-quality PBCR(s) (regional or national)." Currently, in LatinAmerica, most countries have cancer control plans in place; PBCRs cover approximately20% of the region's population, though only 7% are deemed as having high-quality information. No information is available on the extent of use of the information generated by PBCRs for cancer control purposes. Though there are important advances in cancer registration in the region, there is still much to be done. This report also outlines key elementsfor improving cancer surveillance in the region, including 1) involvement of local stakeholders and experts, 2) integration of cancer registries into existing surveillance systems(accounting for the complexities and particularities of cancer surveillance), 3) improvementin data availability and quality, 4) enhanced communication and dissemination, and 5) better linkages between cancer registries and cancer planning and cancer research.
