鼻咽癌筛查成本效果的初步分析
Get PDF目的:评价鼻咽癌新筛查方案的成本和效果。方法:在鼻咽癌高发区中山市进行鼻咽癌筛查,统计癌检出率、早诊率、人均筛查成本、发现早期病例平均费用和早期发现成本系数等指标。结果:共筛查16 712人,确诊鼻咽癌25例,检出率149.59/10万,早诊率76.0%,治疗率100.0%。筛查成本41.56元/人,发现病例费用27 779.82元,发现早期病例费用36 552.40元,按我国人均GDP计算,早期发现成本系数(EDCI)为1.71,按中山市人均GDP计算,EDCI为0.65。结论:相对常见恶性肿瘤鼻咽癌筛查成本较高,但在高发区筛查可以显著提高早诊率,并降低治疗费用
