Abstract

背景与目的正电子发射断层成像检查(positron emission tomography, PET)作为非小细胞肺癌无创分期的手段有逐年增加的趋势,但是它在纵隔淋巴结分期中的作用尚不明了。本文探讨了电视纵隔镜检查术在PET肺癌纵隔淋巴结显像阳性病例中的临床价值。方法2003年11月-2008年11月,对宣武医院收治的术前PET检查提示纵隔淋巴结转移的肺癌患者行电视纵隔镜检查术。对纵隔淋巴结进行病理学检查,病理来自纵隔镜或开胸清扫的纵隔淋巴结,分析纵隔镜诊断纵隔淋巴结转移的敏感性、特异性等。结果本组61例肺癌患者中,男38例,女23例,平均年龄60岁(年龄41岁-81岁)。其中右肺癌41例,左肺癌20例。45例肺癌患者手术病理证实有纵隔淋巴结转移,其中10例N3的患者接受化疗,38例N2的患者给予2个周期的新辅助化疗,并根据检查结果确定是否接受开胸手术。16例无纵隔淋巴结转移的患者翻身行开胸探查、肺癌切除、纵隔淋巴结清扫术。PET的阳性预测值为73.8%(45/61)。电视纵隔镜在肺癌纵隔淋巴结分期中的敏感性、特异性、准确性、阳性预测值和阴性预测值分别为93.8%(45/48)、100%(13/13)、95.1%(58/61)、100%(45/45)、81.3%(13/16)。结论PET在肺癌纵隔淋巴结分期中的阳性预测值较低,电视纵隔镜仍然是肺癌纵隔淋巴结分期的金标准。
