调查河南省肿瘤介入诊疗现状，为微创事业发展策略提供可靠数据。

采用网上电子问卷形式对省297家肿瘤介入专委会会员医院行实名制调查，调查内容为医院级别、职称构成、年手术量等14个方面，并基于医院级别行分层分析。

问卷有效回复率89.2%（265/297）。调查表明：（1）全省肿瘤介入从业者2 201人，每医院平均8.3人，主要来源为介入科和肿瘤科，占84.9%；（2）高级职称218人，占9.9%；（3）35～50岁人数最多，为1 035人，占47%；（4）设备情况为有平板DSA 207家，占78.1%，CT导向165家，占62.3%；（5）有介入病房155家，占58.5%；（6）手术量超500台/年的有88家，占33.2%；（7）介入术式前三分别为TACE、穿刺活检、置管治疗；（8）主要技术学习途径，省内学习209家，占78.7%；（9）有远程医疗中心的208家，占78.5%。三级医院在科室构成、职称构成、年龄结构、病房设置、年手术量、是否有远程会诊中心六方面，与非三级医院比较，有统计学差异（P<0.05）。

河南肿瘤介入事业整体发展良好，以DSA下血管介入为主，CT/US导向介入增长迅猛，应加强非三级医院介入学科建设。
