摘要 目的探讨非小细胞肺癌(NSCLC)组织3'-脱氧-3'-18F-氟代胸苷(18F-FLT)PET显像所示18F-FLT高摄取区与肿瘤细胞高增殖区的一致性。方法选择12例初治、接受根治性手术切除治疗的NSCLC患者。术前3 d行18F-FLT PET CT检查,以最大标准摄取值(SUVmax)的80%为阈值勾画FLT的高摄取区。术后取得完整的肿块并按在体方向还原,4 mm层厚制作肺癌病理大切片并行HE染色及Ki-67染色,Ki-67指数>20%的区域为高表达区,PET图像与病理图像进行配准后比较高摄取区与高表达区位置是否相同。结果 12例患者成功制作病理切片并顺利阅片。5例18F-FLT高摄取区与Ki-67高表达区一致。结论 NSCLC组织18F-FLT高摄取区与Ki-67高表达所代表的肿瘤细胞高增殖区并非完全一致。
