摘要: 对53例星形细胞瘤进行增殖细胞核抗原(PCNA)的免疫组化观察。按照Daumas-Duport方法,本组病例Ⅱ级星形细胞瘤14例,Ⅲ级14例,Ⅳ级25例;它们的PCNA阳性细胞标记指数分别为2.99%,9.73%和38.06%。结果表明:PCNA标记指数随着肿瘤组织病理分级的增高而增大,而且小细胞增殖区的标记指数明显高于多形性瘤细胞区。PCNA能反映肿瘤细胞的增殖速率。此项研究可用于判断星形细胞瘤的恶性程度,为临床判断病人的预后提供一个有价值的指标。

Abstract: Immunohistochemical study of PCNA in 53 cases of astrocytomas was reported. According to the criterion of Daumas-Duport's histological grading,the above mentioned astrocytomas included 14 cases of grade Ⅱ,14 cases of grade Ⅲ and 25 cases of grade Ⅳ. The mean values of immunohistochemical labeling indices (LI) of PCNA are 2.99%,9.73%and 38.06% respectively. The result showed that there existed a positive relation between the histological grading of astrocytomas and the immunohistochemical LIof PCNA,and LIof PCNAin the proliferating areas of small cell type were higher than that of proliferating areas of multiform cell type. PCNA can reflect the proliferating ratio of tumors. We can apply this work for judging the malignancy of astrocytomas and providing a valuable index for clinical prognosis of patients.

Key words: proliferating cell nuclear antigen (PCNA), immunohistochemistry, astrocytomas
