BARRIOS, Enrique et al. Tendencias de la mortalidad por cáncer en Uruguay 1953-1997. Rev. Méd. Urug. [online]. 2002, vol.18, n.2, pp.167-174. ISSN 1688-0390.

Summary Trends in cancer mortality in Uruguay between 1953 and 1997 were evaluated using the data obtained by the Statistics Division of the Ministry of Public Health. The National Institute of Statistics determined risk population. Specific mortality rates and age-adjusted mortality rates were calculated using the world population standards for different anatomic sites or groups of anatomic sites. In order to determine relative risks (RR) of death for each period, data were adjusted by Poisson regressive models. The definitive model included age and period as explicative variables. Lung cancer in men constantly increased until the period 1983-1987 (RR 1.78), followed by a significant decrease (RR for the last period was 1.69). Prostatic cancer increased during the whole period (RR 1.70). On the other hand, gastric and oesophageal cancers showed a remarkable decrease (RR 0.41 and 0.66 respectively). Colo-rectal cancer exhibited an increase until the early 80s becoming stable along the last three five years-periods. For women, rates of mammal cancer significantly increased during the whole period (RR 1.32), broncho-pulmonary cancer showed a notable increase during the last decade (RR 1.58) and recently kidney and ovarian cancers also showed significant increases. Gastric and oesophageal cancers rates decreased along the whole period (RR 0.31 and 0.33). Colo-rectal cancer rate stabilized during the last two decades after an initial increase. Life style changes would be the main causes of these observed trends.
