用石蜡大切片法观察根治术后转归截然不同的102例贲门腺癌标本,分析癌侵犯脉管情况及宿主间质反应的表现。生存5年以上与2年内死于癌的两组间淋巴管与血管阳性例数均有显著差异。癌侵犯脉管以淋巴管最多,且常为多数性。受侵脉管越多、管径越大、预后越差。观察到癌前缘间质中血管周围淋巴细胞套状浸润及血管壁纤维组织增生,认为均是宿主对癌侵犯脉管的抵抗反应表现。
Large paraffin sections were used to observe 102 cases of cardiac adenocarcinoma specimens that were completely different after radical resection and analyzed the appearance of tumor invasion and host interstitial reactions. There were significant differences in the number of lymphatic vessels and vascular positives between the two groups who died of cancer within 5 years and 2 years. Cancer invades the vasculature with the most lymphatic vessels, and is often the majority. The more invasive vessels, the larger the diameter, the worse the prognosis. The infiltration of perivascular lymphocytes and the proliferation of vascular wall tissue in the interstitial space of the cancer were observed, which was considered to be the host’s resistance to the invasion of cancer.
