萧山区1990-2004年大肠癌发病与饮食相关研究

目的：了解萧山区1990-2004年大肠癌的流行病学特征、变化趋势及其相关因素。方法：通过肿瘤登记系统收集1990-2004年大肠癌发病资料，分析15年大肠癌流行特征和变化趋势；并与同期萧山区居民的人均食品消费量进行生态学相关性分析。结果：萧山区大肠癌平均发病率为16．09／10万。占全部肿瘤的9．25％，居第四位；男女性大肠癌发病率随年龄的增长而上升，高发病年龄在45岁以上的年龄组。男性大肠癌发病率高于女性。直肠癌发病率高于结肠癌，但结肠癌的发病趋势比直肠癌快。萧山区大肠癌的发病率与植物油、家禽、猪肉等的人均消费量呈统计学正相关。结论：大肠癌发病率呈上升趋势，饮食因素可能起较大的作用，须针对发病特征及相关影响因素。采取积极有效的预防措施。
