A study was made of 89 cases of alimentary malignancies in Arab patients in the Eastern Province of Saudi Arabia. The pattern of alimentary involvement observed was colo-rectum 43%, stomach 34%, oesophagus 19% and small intestine 4.5%. This finding was in contrast to previous studies in Saudi Arabia which had reported the upper alimentary tract, particularly the oesophagus, as the site most frequently affected. Of the patients 80% were Saudis. The male:female ratio was 3.9:1. A striking feature was the youthfulness of several patients, 44% being under fifty years of age. There were only three cases of alimentary lymphoma. Although colo-rectal schistosomiasis was a moderately frequent finding in the population studied, there was no pathological evidence to support an aetiological association between bilharziasis and large bowel malignancy.
对沙特阿拉伯东部省份阿拉伯患者中的89例消化道恶性肿瘤病例进行了研究。观察到的消化道受累模式为：结肠直肠癌占43%，胃占34%，食管占19%，小肠占4.5%。这一发现与沙特阿拉伯此前的研究形成对比，此前的研究报告称上消化道，尤其是食管，是最常受累的部位。患者中80%为沙特人。男女比例为3.9:1。一个显著特点是有几名患者较为年轻，44%的患者年龄在50岁以下。仅有3例消化道淋巴瘤。尽管在研究人群中结肠直肠血吸虫病是较为常见的发现，但没有病理学证据支持血吸虫病与大肠恶性肿瘤之间存在病因学关联。
