Pattern of primary gastrointestinal tract malignancy among Saudi nationals: A retrospective study.
This histopathological reports from the central laboratory of Riyadh Central Hospital for between 1404 to 1406H (1984 to 1986) were reviewed retrospectively to determine the pattern of primary cancer of the gastrointestinal tract among Saudi nationals. During the study period, a total of 32,990 histopathological examinations were conducted. Neoplasms were identified in 4683 cases (14.2%); 1772 (37.8%) were malignant and 2911 (62.2%) were benign. The stomach (31%), liver (20%), and esophagus (19%) were the most commonly involved organs. The proportional frequencies of gastrointestinal malignancies differ from those seen in Western countries, although the age and sex distribution are similar. The possible etiological factors are discussed and the need for a cancer registry emphasized.
