中文摘要:
      目的:研究p53 、p16 蛋白表达与鼻咽癌CT 表现的关系。方法:经病理证实鼻咽癌50 例, 全部病例做鼻咽轴位平扫, 部 分病例同时做冠状扫描。应用免疫组化SABC 法检测所有病例中的p53 、p16 蛋白的表达。结果:鼻咽癌及鼻咽粘膜慢性炎症中 p53 蛋白表达率分别为60%和10%, p16 蛋白表达率分别为32 %和85%, p53 、p16 表达在两者间的差异有极显著意义(P<0 .005)。 p53 蛋白表达与鼻咽癌分化程度及CT 表现为副鼻窦受累, 颅底骨质破坏相关(P<0 .05)。p16 蛋白表达与鼻咽癌预后及CT 表现 为颈部淋巴结转移相关(P<0.05)。p53 与p16 有相关性(P<0.005)。结论:p53、p16 在鼻咽发生、发展中起重要作用, p53 蛋白表 达与鼻咽癌分化程度、浸润深度、颅底侵犯有一定相关性, p16 蛋白表达与鼻咽癌颈部淋巴结转移和预后有一定相关性, p53、p16 可作为评价鼻咽癌CT 表现恶性度及预后的指标。
英文摘要:
      Objective :To study the relationship between the expression of p53 and p16 protein and CT findings of nasopharyngeal carcinoma( NPC).Mathods :50 patients of NPC were confirmed by biopsy .Axial CT plain scans in all cases, using 6~ 8mm axial scans with 6~ 8 mm spacing , and coronary slice scaning in some cases were performed.And all cases were examined for expression of p53 and p16 protein by immunohistochemical method .Results:1.The positive expression of p53 and p16 in nasopharyngeal carcinoma and chronic nasopharyngeal mucosa inflammation were 60%(30/50), 32 %(16/ 50), 10%(2/20), 85 %(17/20).The difference between p53 and p16 expression was significant (p<0.005).2.p53 protein expression was correlated with histodifferentiation (p<0 .05), tumors with undifferentiated cell had strong p53 abnormal expression.3 .No significant difference was found among clinical stages for p53 , p16 protein expression.4.p16 protein expression was correlated with prognosis and cervical lumph node metastasis (p <0 .05).5.p53 protein expression was correlated with accessory nasal sinuses involvement and skull base destruction (p<0.05).6 .Relationship was found between p53 and p16 gene expression(p<0.005).Conclusion: p53 and p16 might play an important role in the pathegesis and development of nasopharyngeal carcinoma .p53 protein expression was correlated with histodifferentiation, invasive depth and skull base destruction ;p16 protein expression , prognosis and cervical lumphnode metastasis.p16 and p53 could be served as indicator for predicting prognosis and malignancy of CT findings of nasopharyngeal carcinoma .
