Some Epidemiological Measures of Cancer in Kuwait: National Cancer Registry Data from 2000-2009

Abstract

Cancer is the second cause of death in Kuwaiti people after cardiovascular diseases. This study is the first in the country to describe epidemiological measures related to cancer in this population. Data obtained from the Kuwait cancer registry included all Kuwaiti patients between years 2000-2009. Analyses were conducted using age-specific rates, the age-standardization-direct method, 95% confidence intervals (95% CI), cumulative risk by the age of 74 years, limited-duration prevalence, mortality and forecasting to year 2029. It was noted that the commonest cancer sites were colorectal with an age standardized incidence rate (ASIR) of 16.1/100,000 in males and breast (49.4/100,000) in the female population. The trend of cancer incidence (1974-2009) showed no statistically significant change. First causes of death due to cancer were female breast 8(6.4-9.6)/100,000 and lung (males) 8.1/100,000 (6.6-10.0). The risk of developing cancer by the age of 74 was 13.4% (1/8) and 14.3% (1/7) in males and females respectively, and the risk of dying from cancer in the same age group was 1/17 and 1/23. By the end of 2009, prevalent cases represented 0.52% of the Kuwaiti population. In the year 2029, the total number of cancer cases is expected to reach 1200 cases compared to 889 cases in 2009. The most common cancers in Kuwait (breast, colorectal and lung) are largely preventable. Prompt and effective interventional prevention programs that vigorously involve diet, anti-smoking and physical activity for both sexes are urgently required.
