目的:比较p53在子宫内膜样癌和高级别浆液性癌中的表达差异,探讨p53和p16在高级别浆液性癌中表达的相关性。方法:对我院2012~2015年66例高级别浆液性癌或子宫内膜样癌的石蜡包埋组织进行常规HE切片及p16,p53免疫组织化学染色;遵循双盲方式诊断;组织学诊断按WHO第四版标准进行分类,免疫组织化学判定标准为(-)(+-)(+)(++)(+++);再将免疫组化结果数值化,并作统计分析;统计分析运用卡方检验和线性相关分析,并采用SPSS19.0软件进行数值计算,P≤0.05认为具有统计学意义。结果:30例高级别浆液性癌p53表达情况:13例强表达,10例中强表达,7例弱表达,无阴性表达;p16表达情况:8例强表达,9例中等强度表达,10例弱表达,3例完全阴性;36例子宫内膜样癌中,仅1例p53呈强表达,3例中强表达,32例为阴性或弱阳性,同时有2例p16呈中强表达,其余的均为阴性或弱阳性。结论:高级别浆液性癌和子宫内膜样癌组织中p53蛋白含量存在显著的差异(P<0.005);高级别浆液性癌中,p16和p53显示出一定程度的相关性(P≤0.05)。
目的:比較p53在子宮內膜樣癌和高級彆漿液性癌中的錶達差異,探討p53和p16在高級彆漿液性癌中錶達的相關性。方法:對我院2012~2015年66例高級彆漿液性癌或子宮內膜樣癌的石蠟包埋組織進行常規HE切片及p16,p53免疫組織化學染色;遵循雙盲方式診斷;組織學診斷按WHO第四版標準進行分類,免疫組織化學判定標準為(-)(+-)(+)(++)(+++);再將免疫組化結果數值化,併作統計分析;統計分析運用卡方檢驗和線性相關分析,併採用SPSS19.0軟件進行數值計算,P≤0.05認為具有統計學意義。結果:30例高級彆漿液性癌p53錶達情況:13例彊錶達,10例中彊錶達,7例弱錶達,無陰性錶達;p16錶達情況:8例彊錶達,9例中等彊度錶達,10例弱錶達,3例完全陰性;36例子宮內膜樣癌中,僅1例p53呈彊錶達,3例中彊錶達,32例為陰性或弱暘性,同時有2例p16呈中彊錶達,其餘的均為陰性或弱暘性。結論:高級彆漿液性癌和子宮內膜樣癌組織中p53蛋白含量存在顯著的差異(P<0.005);高級彆漿液性癌中,p16和p53顯示齣一定程度的相關性(P≤0.05)。

Objective:To compare the expression of p53 in high grade serous carcinoma and endometrioid carcino-ma,and to explore the correlation between p16 and p53 in high grade serous carcinoma.Methods:Paraffin embedding tis-sues of 66 cases of serous carcinoma or endometrial carcinoma in our hospital from 2012 to 2015 were condected routine HE staining and immunohistochemical staining.Diagnosis was made based on the double blind method .The histological diag-nosis was made according to WHO fourth edition and immunostaining results were classified as:(-)、(+-)、(+)、(++)、(+++),then quantified and analyzed.P<0.05 was with statistical significance.χ2 test and Linear correlation analysis were used to do statistical analysis.Results:In 30 cases daignosed as high grade serous carcinoma,p53 was expressed strong in 13 cases,moderate intensity in 10 cases ,weak in 7cases .p16 was expressed strong in 8 cases,moderate intensi-ty in 9 cases,weak in 10 cases ,and negative in 3 case.In 36 cases of endometrioid carcinoma,p53 was expressed strong in only case ,with moderate intensity expression in 3cases ,and negative or weak expression in 32 cases.Among which, p16 was expressed moderate intensity in 2 cases ,negative and weak in the other cases.Conclusion:There is significant difference in the expression of p53 between serous carcinoma and endometrial carcinomas (P<0.005),and a certain de-gree of correlation exists between the expression of p16 and p53 in high grade serous carcinoma(P<0.05).
