Zhongguo shiyan zhenduanxue, 2020 垂体腺瘤是起源于腺垂体的良性肿瘤,约占颅内肿瘤10.5%[-15.6%1],根据Fernandez等人的研究,随着检查技术的发展,近年来临床上垂体腺瘤的发病率上升至75-113/10万人[2],一些垂体腺瘤表现出侵袭性、术后复发等特性[3]。Ki-67是一种抗原,反应肿瘤增殖能力,可以在多种肿瘤中表达,如肺癌、前列腺癌、乳腺癌、子宫癌、

Zhongguo shiyan zhenduanxue, 2021 乳腺癌是一种临床上较为常见的妇科恶性肿瘤,严重威胁着我国女性生命健康[1]。在乳腺癌患者中,有很多患者由于病灶转移至其他脏器而引发死亡。据资料显示,乳腺癌转移十分迅速,在早期检查时就发生转移者可达10%,而仅有20%的患者在确诊乳腺癌后可生存5年以上[2]。因此,危及乳腺癌患者生命的关键在于乳腺癌的复发和转移。对于以往乳腺癌的诊断,常采用影像学方法来检查乳腺癌原发病灶。然而,该方法只有病灶肿物直径大于5mm时才可被捕捉到,故无法及时发现肿瘤是否转移[3]。因此,对于乳腺癌转移和诊断的研究,

The Study of DNA Ploid Analysis and the Expression of Ki-67 to the Early Diagnosis of Breast Tumor [PDF]
, 2013 目的：评价乳管灌洗液中脱落细胞DNA倍体分析及Ki-67表达对乳腺肿瘤早期诊断的价值，以提高早期乳腺癌的诊断率，并通过脱落细胞Ki-67的表达情况进一步评估乳腺癌的恶性程度。 方法：对乳头溢液的患者进行乳管镜检查，收集乳管灌洗液，共60例，分为乳管镜下非肿块组（I组）30例，乳管镜下肿块组（II组）30例。对其分别进行HE染色行细胞学检查，Feulgen染色行DNA倍体分析，采用配对资料的X2检验，并进一步行关联性分析，分析两者与术后病理的相关性，以确定其诊断价值 ...

Zhongguo shiyan zhenduanxue, 2015 乳腺叶状肿瘤（Phyllodes tumour,PT）,原名乳腺叶状囊肉瘤,1838年由Mailer首次描述并命名,但由于该名称常引起误解,自1982年起WHO开始使用中性名称"叶状肿瘤"。该肿瘤最典型的特征是形成叶状结构,突向囊腔内,由间质和上皮两种成分组成,生物学行为难以预测。叶状肿瘤可以侵犯邻近乳腺组织,还可以复发、转移和恶变。目前WHO按照组织学特征将PT分为良性、交界性和恶性 ...
