  近日,北京协和医学院中国医学科学院肿瘤医院病理科和中国中医科学院广安门医院的研究人员共同发表论文,旨在探讨进展期食管胃交界腺癌临床病理特征、Siewert分型、Lauren分型与预后的关系,观察新版AJCC分期指南在食管胃交界腺癌中的适用性。研究指出,食管胃交界腺癌肿瘤最大径、浸润深度、分化程度、Lauren分型等临床病理特征与预后相关,其中AJCC第7版分期指南中所参照的食管癌N分期标准并不能揭示预后意义,提示食管胃交界腺癌有其独特的临床病理学特征,有必要研究并建立食管胃交界腺癌适用的分期标准,而不仅仅是参照食管癌或胃癌现有标准。该文发表在2012年第9期《世界华人消化杂志》上。

  回顾性分析319例具有完整随访资料的进展期食管胃交界腺癌的临床病理特征,采用Kaplan-Meier方法进行生存分析。

  319例进展期食管胃交界腺癌的1年、3年、5年总生存率分别为62%、44%和35%。局限型患者生存率高于浸润型;肿瘤最大径<5cm患者生存率比5cm以上患者高;肿瘤分化程度、浸润深度(T分期)和淋巴结转移与低生存率相关;按照AJCC第7版中N分期标准分组,组间未见生存差异,而将淋巴结转移数目以10为界,发现10个以上淋巴结转移的病例生存率显著低于10个以内者;Lauren弥漫型病例生存率显著低于肠型和混合型,而肠型和混合型之间无明显差异;Siewert三型病例之间生存率无明显差异。
