摘要
目的通过18F-FDG PET/CT和MSCT联合扫描判断胸内淋巴结是否转移,评价贴壁生长为主型肺腺癌的预后价值。方法回顾性分析39例进行18 F-FDG PET/CT和MSCT联合扫描的贴壁生长为主型肺腺癌患者的资料。结果单因素回归分析显示:SUVmax,TDR,mDmax以及AIS比例对于判断胸内淋巴结是否有转移有统计学意义。mDmax的AUC与SUVmax,TDR和AIS比例的AUC相比较均有统计学意义。SUVmax,TDR,mDmax及AIS比例之间有显著相关性。结论贴壁生长为主型肺腺癌患者术前行18F-FDG PET/CT和MSCT联合扫描有助于判断是否发生胸内淋巴结转移,特别是当患者无法进行手术时。
Objective To evaluate the clinical usefulness value of PET/CT comlined with MSCT scan for lepidic predom inant adenocarcinoma （LPA） features. Methods PET/CT and MSCT scan were performed in thirtynine patients with fo cal peripheral LPAs. Results Univariate analysis revealed that SUVmax, TDR, mDmax, the ratio of adenocarcinoma in situ （AIS） component were related to intrathoracic lymph node metastases. The AUC of mDmax was significant lower than the AUC of SUVmax, TDR and AUC of the ratio of AIS component. There was significant correlation between SU Vmax, TDR, mDmax and the ratio of AIS component. Conclusion PET/CT combined with MSCT scan were performed in patients with LPAs at preoperative stages, which can predict the incidence of intrathoracic lymph node metastases, e ven for inoperable patients.
