我国部分地区PET／CT检查人群和病种构成分析

Analysis of the proportion of the patients referred to PET/CT in some areas of China

目的了解我国PET／CT使用实际状况，为推广PET／CT提供数据。方法收集10家三甲医院PET／CT中心2006年6月-8月共3018例PET／CT受检者资料进行分析。结果（1）检查目的：诊断肿瘤、体格检查和其他目的的受检者构成比分别为63．0％，32．9％和4．1％。（2）诊断：PET／CT诊断恶性肿瘤的真阳性率93．5％；PET／CT为38．6％的单纯转移癌受检者找到原发灶；在病理检查结果为良性病变，但临床仍要求鉴别占位性病变良恶性的受检者中，PET／CT发现23．3％的受检查者有恶性肿瘤。（3）受检者个人情况：不同月收入受检者例数前3位的组内构成比：〉6000元者30．4％，4001～6000元者28．8％，2001～4000元者18．6％；不同医疗社会保障受检者例数前3位的组内构成比：自费医疗者55．6％，国家基本医疗保险者26．5％，公费医疗者11．4％；不同职业受检者例数前3位的组内构成比：机关事业单位工作人员21．9％，退休人员15．6％，企业领导11．8％；不同受教育程度受检者例数前3位的组内构成比：大学（含大专）48．2％，高中（含中专或技校）21．3％，初中13．8％。结论PET／CT在肿瘤学中有重要的临床应用价值。如何充分利用现有资源，充分发挥其效益是亟待解决的问题。

Objective The aim of this study was to analyze the current practical status of PET/CT application in China and for provision of data in support of promoting the utility of this imaging modality. Methods All 3018 PET/CT cases from 10 hospitals in the top 3 rankings were recruited in the data analysis from June to August, 2006. Results （ 1 ） Reason for referral ： the proportions of patients referred for oncologic diagnosis, check-up and other reasons were 63.0% , 32.9% and 4. 1% , respectively. （2） Diagnosis： PET/CT had a 93.5% true positive value in diagnosing malignant tumors, 38.6% success rate in identifying the primary malignancy in patients presented with metastases, and 23.3% discovery rate of malignancy in patients with space-occupying lesions pathologically diagnosed as benign but clinically requested to differentiate between benignity and malignancy. （3） Patient data： the proportion of patients in the top 3 income groups （monthly） was： 〉 ￥ 6000, 30.4% ; ￥ 4001 - 6000, 28.8% ; and ￥ 2001 - 4000, 18. 6%. The proportion of patients in the top 3 medical insurance or security category： self-paid or uninsured, 55.6% ; national basic insurance scheme, 26.5% ; public paid fund, 11.4%. The top 3 groups of patients categorized according to profession were： departmental officials, 21.9% ; retiree, 15.6% ; company leaders, 11.8%. The top 3 groups according to level of education were： university （including college）, 48.2% ; high school （including technical training schools）, 21.3% ; primary school, 13.8%. Conclusions PET/ CT holds an essential clinical value in oncology. It is an utmost issue on how to fully utilize the existing resources with a purpose to achieve maximal benefit and return.
