摘要 目的:探讨^(18)FDG PET-CT诊断食管癌淋巴结转移的优势及确定淋巴结放疗靶区的可行性。方法:选取本院于2016年7月—2017年7月收治的28例食管癌患者,探讨PET-CT在诊断淋巴结转移的优势,另以PET-CT、CT检查为基础,明确临床靶区(CTVN)与淋巴结大体肿瘤靶区(GTVN),依据术后病理检测结果,剖析在淋巴结放疗靶区确定中PET-CT的应用价值。结果:CT确定12例GTVN(GTVN-CT)与病理相一致,PET-CT确定18例GTVN(GTVN-PET-CT)与病理相符。PET-CT造成GTV缩小的3例共涉及3组淋巴结,其中,临床靶区缩小1例;GTVN-PET-CT>GTVN-CT的12例共涉及淋巴结22组,其中CTVN亦扩大8例。GTVN-PET-CT>GTVN-CT亚组分析结果得知,PET-CT确定淋巴结GTV准确率较CT,明显高于后者(P<0.05)。结论:PET-CT在诊断淋巴结转移中具有突出优势,可将其当作确定与优化食管癌淋巴结放疗靶区的优先工具。
