Oesophageal-cancer-derived death in the population of Belgrade in a period 1989-2006

BACKGROUND/AIM: Oesophageal cancer is the sixth most common cause of death from all malignant tumors in the world (fifth in men, eighth in women). This cancer was estimated to account for about 529 000 new cases and about 442 000 deaths in the year 2007. In the year 2002 the highest standardized mortality rates (per 100 000 habitants) of oesophageal carcinoma were noticed in the East Asia (men/women: 18.8/7.7) and East Africa (18.6/7.8), while the lowest were noticed in the Middle Africa (1.4/0.2) and West Africa (1.3/0.5). The aim of this descriptive epidemiologic study was to analyze epidemiologic situation of oesophageal cancer in Belgrade population during the period 1989-2006, using mortality data. METHODS: Mortality data were collected from the City Organization for Statistics. In data analysis we used mortality rates which were standardized directly using those of the world population as the standard, and proportions. A denominator for mortality rates was calculated using the Belgrade population which was an average of the two latest register years (1991 and 2002). In order to analyze trend mortality from oesophageal cancer we used linear trend. RESULTS: In Belgrade deaths from oesophageal cancer accounted for about 5.2% of all malignant tumors of intestinal system in male population, and 2.4% in female population. This cancer is, according to standardized mortality rates (per 100 000 habitants), on the fifth place in Belgrade population behind colorectal, stomach, pancreatic, liver and cholecystic cancer. During the period 1989-2006 in Belgrade 44 persons died from oesophageal carcinoma on the average each year, mainly men (75%), and the rest were women (25%). In male population during the same period we noticed a significant increase in trend mortality (y = 1.61 + 0.06x, p = 0.001), while in female population the increase of mortality was not significant. The male/female oesophageal cancer mortality ratio was 3:1. Mortality rates for oesophageal cancer rise with age in both sexes and they are highest in the age group of 70 and more years. Significant increase in mortality from oesophageal cancer was noticed in age groups 20-29 and over 70 in male population, and age group 40-49 in female population. CONCLUSION: Increasing trend in oesophageal mortality suggests the necessity for improving measures of primary prevention including education about risk factors for this carcinoma (smoking, alcohol consumption, hot food and drinks), early diagnosis, and treatment.
