目的:探讨双原发癌第二原发癌中 p53、CyclinD1和 Ki67表达的意义及其与双原发癌临床病理特征的相关性。方法:采用免疫组化法对43例符合标准并确诊为双原发恶性肿瘤的第二原发癌标本进行 p53、CyclinD1和 Ki67的检测。结果:p53、CyclinD1、Ki67在双原发癌第二原发癌标本的阳性表达率分别为60.5%、30.2%、65.1%。p53的阳性表达与间隔时间、病理分级、淋巴转移密切相关(P <0.05),CyclinD1及Ki67阳性表达与病理分级、淋巴转移密切相关(P <0.05);p53与 CyclinD1、Ki67的表达均呈正相关性(r=0.313,P =0.041;r =0.319,P =0.037)。结论:p53、CyclinD1、Ki67蛋白高表达与双原发癌第二原发癌的恶性生物学行为密切相关,联合检测 p53、CyclinD1、Ki67在双原发癌中的表达对评估预后具有指导意义,并提示第二原发癌在基因水平上可能出现了某种程度的异常,尚需进一步研究。
目的:探討雙原髮癌第二原髮癌中 p53、CyclinD1和 Ki67錶達的意義及其與雙原髮癌臨床病理特徵的相關性。方法:採用免疫組化法對43例符閤標準併確診為雙原髮噁性腫瘤的第二原髮癌標本進行 p53、CyclinD1和 Ki67的檢測。結果:p53、CyclinD1、Ki67在雙原髮癌第二原髮癌標本的暘性錶達率分彆為60.5%、30.2%、65.1%。p53的暘性錶達與間隔時間、病理分級、淋巴轉移密切相關(P <0.05),CyclinD1及Ki67暘性錶達與病理分級、淋巴轉移密切相關(P <0.05);p53與 CyclinD1、Ki67的錶達均呈正相關性(r=0.313,P =0.041;r =0.319,P =0.037)。結論:p53、CyclinD1、Ki67蛋白高錶達與雙原髮癌第二原髮癌的噁性生物學行為密切相關,聯閤檢測 p53、CyclinD1、Ki67在雙原髮癌中的錶達對評估預後具有指導意義,併提示第二原髮癌在基因水平上可能齣現瞭某種程度的異常,尚需進一步研究。

Objective:To Investigate the significance of p53,CyclinD1 and Ki67 expression,as well as their corre-lation with the histopathological characteristics in the second primary cancer of patients with double primary cancer. Methods:Immunohistochemical method was used to determine the p53,CyclinD1 and Ki67 score of the tissue sam-ples.Tissue samples were procured from the second primary cancer sites of 43 patients who met the diagnostic criteria of double primary cancer.Results:The expression rate of p53,CyclinD1 and Ki67 in the second primary cancer site were 60.5%,30.2% and 65.1% respectively.p53 expression showed statistically significant association with tumor occurrence interval,pathological grading and nodal metastasis(P <0.05).Positive correlation was detected between the expression of cyclinD1,Ki67 and the expression of p53(r =0.313,P =0.041;r =0.319,P =0.037).Conclu-sion:High expression rate of p53,CyclinD1 and Ki67 proteins in double primary cancer is highly associated with the malignant behavior of the secondary cancer site.It's detection plays the potentially valuable role in becoming a clinical prognostic factor.Further study is required in determining genetic alterations in the secondary cancer site.
