Cancer in the Eastern Region of Saudi Arabia: A population-based study (1987-1988)

Abstract

This study presents the findings of the first population-based tumor registry in the Eastern region (ER). Data on all cancer sites, in 1987 and 1988, were captured from all health facilities in the ER. A regional population census was obtained from regional health authorities. Cancer deaths were obtained from death registries. Age-specific rate, crude incidence rate (CIR), age-standardized incidence rate (ASR) and relative age-standardized incidence rate (%ASR) were compared with available population-based data from 137 tumor registries. 1559 primary cancer cases were captured. The CIR and ASR/100,000/year for cancer among Saudi males were respectively 59.8 and 125.7. The corresponding rates among Saudi females were 43.6 and 95.5. These rates rank very low on the international scale. Cancer sites with the highest %ASR among Saudi males were lung, lymphomas, leukemias, urinary bladder and tumors of uncertain primary. For Saudi females, these sites were breast, leukemias, tumors of brain and nervous system, thyroid and tumors of uncertain primary. Lung cancer was the leading cause of death from cancer among Saudi males. The first regional population-based cancer registry in Saudi Arabia was established in 1987. The overall cancer ASR in the ER is low. The leading cancer sites with the highest %ASR are lung in Saudi males and breast in Saudi females.
