彝族恶性肿瘤现况

Current status of malignant tumor in Chinese Yi populations

目的：了解彝族恶性肿瘤发病情况，分析影响防治相关因素。方法：收集凉山州第一人民医院3年的恶性肿瘤病历资料，分析彝族恶性肿瘤发病特征和影响发病的有关因素。结果：彝族肿瘤患者就诊年龄分布，男性高峰在50～60岁，女性高峰在40-50岁，与汉族年龄越大发病越多有差异。肿瘤顺位，彝汉也有不同，彝族男性首位肿瘤是胃癌，汉族是肺癌，彝族女性首位肿瘤是宫颈癌，汉族是卵巢癌。彝族肝癌患者就诊人数占第二位，为全部肿瘤就诊者构成的17．43％。结论：彝族消化道肿瘤就诊者构成比高，不良生活习惯可能是原因之一。
