MSCT在肺癌术后肺功能的预测中的应用

Application of MSCT in the Prediction of Lung Function After Lung Cancer Surgery

目的探究多层螺旋CT(MSCT)在肺癌术后肺功能预测中的价值。方法选择2017年2月至2018年2月间我院胸外科收治的拟行肺切除肺癌患者纳入研究,所有患者均于术前及术后2个月时进行MSCT扫描及临床肺功能检查,根据术前CT测得的肺容量、肺功能检查测得的第一秒用力呼气量(FEV1)、用力肺活量(FVC)及手术切除范围估算患者术后FEV1、FVC,并与术后肺功能检查测定的FEV1、FVC进行比较,分析相关性。结果术前MSCT肺功能预测FEV1、FVC与术后临床肺功能检查所测FEV1、FVC比较差异均无统计学意义(P>0.05);MSCT预测肺癌患者术后FEV1及FVC指标与术后临床肺功能检查所测FEV1、FVC均呈正相关(r=0.912、0.927,P<0.05)。结论 MSCT在肺癌切除术术后肺功能中具有较高的预测价值,可作为肺癌切除术前风险评估指导工具。

Objective To investigate the value of multi-slice spiral CT(MSCT)in the prediction of lung function after lung cancer surgery.Methods Patients with lung cancer who underwent selective pneumonectomy in thoracic surgery of the hospital from February 2017 to February 2018 were enrolled.All patients underwent MSCT scan and clinical lung function examination before and at 2 months after surgery.The lung volume measured by preoperative CT,forced expiratory volume in 1 s(FEV1),forced vital capacity(FVC)and surgical resection range measured by lung function examination were performed to estimate postoperative FEV1 and FVC.And they were compared with FEV1 and FVC measured by postoperative lung function examination.The correlation was analyzed.Results There was no significant difference in FEV1 and FVC measured by preoperative MSCT and postoperative clinical lug function examination(P>0.05).The postoperative FEV1 and FVC in patients with lung cancer predicted by MSCT were positive correlated with those measured by postoperative clinical lung function examination(r=0.912,0.927,P<0.05).Conclusion MSCT is of high predictive value in lung function after lung cancer resection,which can be used as a guiding tool of preoperative risk assessment for lung cancer resection.
