CHEST美国胸科医师学会官方微信平台报道：正电子发射计算机断层显像（PET）通常用于可疑肺癌的诊断。计算机生物电导（CB）是预测肺中的可疑异常是良性还是恶性的一种无创手段。在该研究中，研究人员发现在对可疑病变进行活组织检查前，将CB与PET结合可提高电脑断层扫描检测到的潜在癌性病变的诊断效果。
在这项前瞻性分析中，研究人员发现，与仅依赖PET相比，CB结果与PET相结合可提高区分恶性与良性条件的能力。
“在中国，肺癌是癌症死亡的主要原因，且会对健康带来巨大的负担和费用。经证明， CB测量结果与标准PET扫描结合是帮助诊断肺癌患者的一个有用、无创诊断工具”， 复旦大学附属中山医院Yang Dawei博士说道。
在2016年的世界《胸科》大会上，还将分享其它的研究成果。该项研究论文摘要可在 《胸科》期刊网站查阅。
Combining computed bioconductance measurement with PET could improve evaluation of suspicious lung lesion found by CT
Positron Emission Tomography (PET) is used commonly in the diagnosis of suspected lung cancer. Computed bioconductance (CB) being investigated as a non-invasive way to predict whether an suspicious abnormality in the lung is benign or malignant. In this study, researches found that CB combined with PET before biopsy of suspicious lesions could improve diagnostic effectiveness of potentially cancerous lesions detected by CT scan.
In this prospective analysis, researchers found CB results combined with PET improved the ability to distinguish malignant from benign conditions compared with PET alone.
“In China, lung cancer is the leading cause of cancer mortality and causes huge health burdens and expense. Adding CB measurement to standard PET scanning could prove to be a useful, non-invasive diagnostic tool for aiding diagnosis of patients with lung cancer” said Dr. Dawei Yang, lead author, Zhongshan Hospital Fudan University in Shanghai, China.
Further study results will be shared at CHEST World Congress 2016. The study abstract can be viewed on the journal CHEST website.
