Abstract： 目的探讨18F-脱氧葡萄糖-正电子发射体层显像(18F-FDG PET)在非小细胞肺癌(NSCLC)临床分期中的价值.方法 105例NSCLC患者于放射治疗前行18F-FDG PET检查,进行PET分期,并将PET分期和CT分期结果进行比较分析.结果 18F-FDG PET扫描使38例NSCLC患者分期改变,其中分期升级31例,分期降级7例.21例分期升级者PET检查发现了远处转移灶,其治疗方案由根治性治疗改为姑息性治疗;6例分期降级者进行了根治性手术治疗,其中5例PET分期与病理分期一致.PET发现远处转移灶的几率随PET扫描前分期的升级而上升,其中Ⅰ期10.0%(2/20),Ⅱ期14.3%(3/21),Ⅲ期25.0%(16/64).结论 18F-FDG PET显像改变了36.2%(38/105)NSCLC患者的临床分期,影响了其治疗策略.18F-FDG PET显像对NSCLC患者的临床分期有重要的参考价值.
