本文应用维多利亚兰和HE的复合染色对100例大肠癌手术标本进行了血管浸润的研究,其阳性率为69％。血管浸润程度和病理类型有关,和淋巴管浸润成正相关。随着浸润深度的增加,血管浸润阳性率增高,程度加重。生长形态和血管浸润有关。大肠癌血管浸润可以反映其生物学特性。 In this paper, the vascular infiltrative study was performed on 100 colorectal cancer surgical specimens using the complex staining of Victorian blue and HE. The positive rate was 69%. The extent of vascular invasion is related to the pathological type and positively related to lymphatic infiltration. As the depth of infiltration increases, the positive rate of vascular infiltrate increases and the degree increases. The growth pattern is related to vascular invasion. Colorectal cancer vascular infiltration can reflect its biological characteristics.
