The geographic variation and sex disparity in oesophageal cancer across Central and South America may reflect differences in the prevalence of tobacco smoking and alcohol consumption which highlights the need to implement and/or strengthen tobacco and alcohol control policies. Maté consumption, obesity, diet and Helicobacter pylori infection may also explain the variation in oesophageal cancer rates but these relationships should be evaluated. Continuous monitoring of oesophageal cancer rates is necessary to provide the basis for cancer prevention and control in the region.
Background: Uruguay is the southamerican country which has the highest cancer incidence and mortality rates. The National Cancer Registry collects data on cancer cases nationwide since 1989 and has reached high quality standards in the last decades. This is the first report on incidence trends. Methods: Data from the National Cancer Registry of all new cases of invasive cancer from twelve sites diagnosed in 2002-2015 was analyzed. Age-standardized rates were calculated. Trends of incidence rates were analyzed using joinpoint regression models. Results For both, men and women, incidence rates trends for all cancer sites, colo-rectal and bladder cancer remained stable. Esophageal and gastric cancers descend while Thyroid and kidney cancer incidence increased. In men lung cancer decreased; testicular cancer increased, and prostate cancer increased at the beginning of the period and decreased in the final years. In women; lung cancer increased, breast cancer remained stable and cervical cancer presented a significant decline from 2005 to 2010 and reached a plateau since then. Conclusion: Cancer incidence dynamics are complex and affected not only by Public Health policies such as tobacco control, vaccination and screening programs, but also by environmental and life style changes and the attitude of the medical community towards the application of diagnostic and therapeutic tools. The aim of this paper is to analyze cancer incidence time trends in the country and provide possible explanations to them.
Uruguay has the highest colorectal cancer incidence rates in Latin America. Previous studies reported a stable incidence and a slight increase in mortality among males. We aimed to assess colorectal cancer incidence (2002–2017) and mortality trends (1990–2017) by age groups and sex, using data from the National Cancer Registry. Annual percent changes (APCs) were estimated using joinpoint regression models. We included 27,561 colorectal cancer cases and 25,403 deaths. We found an increasing incidence among both males and females aged 40–49, with annual increases of 3.1% (95%CI: 1.21–5.03) and 2.1% (95%CI: 0.49–3.66), respectively, and an increasein the rate in older males (70+) of 0.60% (95%CI: 0.02–1.20) per year between 2002 and 2017. Mortality remained stable among those younger than 50, whereas it decreased for older females aged 50–69 and 70+ (APC: −0.61% (−1.07–0.14) and −0.68% (−1.02–0.34), respectively), and increased for the oldest males (70+; APC: 0.74 (0.47–1.01)). In conclusion, we found rising colorectal cancer incidence accompanied by stable mortality in young adults. Sex disparities were also found among the older adults, with a more favorable pattern for females. Exposures to dietary and lifestyle risk factors, and inequalities in access to and awareness of screening programs, are probably among the main underlying causes and deserve further investigation.
Background: Uruguay has the highest cancer incidence and mortality rates in Latin America. The National Cancer Registry of Uruguay, which has been in operation since 1992, provides epidemiological information on incidence and mortality at the country level. Objective: The objective of this article is to update the incidence and mortality figures by reporting the information for the period 2013-2017. Methods: All incident cases of invasive neoplasias except non-melanoma of the skin and all cancer deaths that occurred from 2013 to 2017 were analyzed. Age-standardized rates were calculated by the direct method, using the world standard population. Complementary, incidence (2002-2017) and mortality (1990-2017) trends were studied for the leading sites. Results: Among females, the most common cancers are breast, colon and rectum, lung, cervix and thyroid. The most frequent cancers in males are prostate, lung, colon and rectum, bladder and kidney. Lung, prostate and colorectal cancer are the leading causes of cancer death in males while breast cancer is the first cause of cancer death among females. Conclusions: Although cancer mortality has declined monotonously since 1990, cancer control is a challenge for Uruguay, wherein breast, lung and prostate cancer have very high incidence while the country must still make an effort to reduce other cancers that are very common in economically less favored countries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
