EXPRESSION OF P53 PROTEIN AND PROLIFERATING CELL NUCLEAR ANTIGEN IN HUMAN GESTATION TROPHOBLASTIC DISEASE

To study the relationship between p53 protein, proliferating cell nuclear antigen (PCNA) expression and benign or malignant gestational trophoblastic disease (MGTD). Methods: The histotomic sections of 48 patients with gestational trophoblastic disease and 24 patients of normal chorionic villi were stained using immunohistochemistry. The monoclonal antibodies were used to determine p53 protein and PCNA. Results: The frequency of p53 and PCNA positive expression were significantly different among the chorionic villi of normal pregnancy, hydratidiform mole (HM) and MGTD. But neither p53 nor PCNA has any relation with the clinical staging or metastasis of MGTD. Conclusion: Both P53 and PCNA are valuable in diagnosis of human gestational trophoblastic disease.

p53蛋白和增殖细胞核抗原在妊娠滋养细胞疾病中的表达

目的 观察p53蛋白、增殖细胞核抗原(PCNA)与妊娠滋养细胞疾病(GTD)及其良恶性之间的关系。方法 对48例GTD和24例正常妊娠绒毛组织的石蜡标本进行p53蛋白和PCNA免疫组化染色,比较各类疾病中二者的阳性率。结果 p53蛋白与PCNA在正常绒毛、良性葡萄胎、恶性滋养细胞疾病3组中表达均有极显著性差异(P<0.01)。结论 p53蛋白和PCNA在GTD的生物行为中有着相似的意义。

滋养细胞增生与病变恶性程度相关性研究进展

妊娠滋养细胞肿瘤是一组早期即可出现转移的肿瘤,如何及早、准确的预测此类疾病发展预后受到很多学者的关注。目前,增殖标记物在肿瘤预后的预测方面的意义受到越来越多的重视。该文分析了近几年对K i-67、增殖细胞核抗原、核仁组成区相关嗜银蛋白等3种细胞增殖标记物在滋养细胞疾病中的研究成果,综述其在滋养细胞疾病中增殖程度与病变恶性程度的关系。
