卵巢浆液性交界性肿瘤中clusterin的表达

目的探讨凋亡抑制因子clusterin在卵巢浆液性肿瘤中发生、发展的作用及其与bcl-2、Ki-67表达的关系。方法免疫组化sP法检测clusterin、bcl-2、Ki-67在20例卵巢浆液性囊腺瘤,28例浆液性交界性肿瘤,26例浆液性囊腺癌标本中的表达。结果clusterin在囊腺瘤、交界性肿瘤、囊腺癌中的阳性率分别为40％,67．9％,96．2％。囊腺癌中的clusterin与Ki-67的表达水平均明显高于囊腺瘤（P〈0．05）和SBOT（P〈0．05）。交界性肿瘤中有腹水的患者clusterin阳性率要明显高于无腹水者（P=0．0390）,Ki-67在有腹膜种植的患者阳性率要明显高于无腹膜种植者（P=0．0473）。且两者的表达成正相关。结论clusterin基因可能通过抑制凋亡在卵巢浆液性肿瘤的发生发展中起重要作用。clusterin与Ki-67结合起来分析可能作为鉴别SBOT与浆液性癌的辅助指标。     

卵巢浆液性及黏液性交界性肿瘤的研究进展

长期以来对卵巢交界性肿瘤（borderline ovarian tumors,BOT）命名及病理诊断标准一直存在不同的意见。经过30余年的探索,对其本质认识逐步深入,特别是2003年8月在美国马里兰州贝塞斯达举行的卵巢交界性肿瘤工作会议,就卵巢交界性肿瘤的某些病理学方面的分歧取得了较一致的意见。本文就近年卵巢浆液性及黏液性交界性肿瘤的命名、形态学特征、病理诊断以及预后等方面的进展作如下综述。     

卵巢黏液性交界性肿瘤的诊断

卵巢上皮性肿瘤的分类中,交界性肿瘤的诊断受人重视,它既是卵巢肿瘤病理学的一大进展,提出了特殊的概念和规律[1],又引起了混淆和争议.     

卵巢浆液性肿瘤的电镜诊断

对20例卵巢浆液性肿瘤进行了电镜观察,并与光镜观察对比。提出分支管道样腔、纤毛及顶浆分泌是浆液性肿瘤电镜诊断的主要指标。而核不规则形伴细桥和分叶核形成、核内胞浆包涵体及畸形核仁是确认细胞指征。纤毛杆的大量出现是肿瘤细胞分化成熟的表现,但纤毛杆缺如不一定是不成熟的征象。核糖体丰富及粗面內质网减少是癌细胞分化低下的表现?疚奶致哿私盒韵傧宋龅拿?认为改成浆液性纤维腺瘤更符合肿瘤命名原则。     

卵巢交界性浆液性肿瘤17例临床病理分析

目的对卵巢交界性浆液性肿瘤的临床特征、病理学特点进行分析,探讨其诊断及鉴别诊断。方法收集17例卵巢交界性浆液性肿瘤患者的临床资料,对组织病理学表现进行分析,并复习相关文献。结果17例卵巢交界性浆液性肿瘤患者,年龄42~65岁,平均年龄51.2岁。17例患者中有4例患者常有下腹不适和腹胀、尿频等症状,有5例患者有经期延长与出血量多的症状,还有2例患者因肿瘤破溃导致急腹症。结论卵巢交界性浆液性肿瘤的患者,预后相当好,5年生存率为90%。但仍有10%的患者预后不好。     

卵巢浆液性交界瘤近期讨论的诊断问题

卵巢浆液性交界瘤（serous-borderline ovarian tumrs．SBOT）肿瘤分型、腹膜种植以及浆液性癌的诊断一直意见不一。2003年在美国Bethesda成立了卵巢交界瘤工作组,对以往文献中报道的卵巢交界瘤的报道资料进行了分析。Bell认为卵巢浆液性微乳头交界瘤（micripapillary type serons-bordedine ovarian tumors）与典型的S-BOT比较,差异不明显,因而将前者留在交界瘤范围内比较适当。     

卵巢交界性粘液性和浆液性瘤

通过78例粘液性和浆液性交界瘤的随访,进一步阐明交界瘤是介于良恶性之间的一类肿瘤。其病理特点为:有一定程度组织结构和细胞形态的异型性,但无明显的间质浸润。其临床分期绝大多数为Ⅰ期。5年存活率分别为84%与78%。加强对交界性瘤这一概念的认识,将有助于临床制定正确的治疗方案。

Genetic alterations of serous borderline tumors of the ovary compared to stage I serous ovarian carcinomas

Borderline tumors of the ovary comprise 10-20% of all epithelial ovarian tumors, and are placed between clearly benign and obviously malignant ovarian tumors. The issue of whether borderline tumors are precursors of invasive carcinoma or distinct clinical entities, however, is still the subject of discussion. To increase our understanding in relation to this issue, the aim of our study was to analyze both serous borderline and invasive ovarian tumors, and to investigate early carcinogenesis in serous ovarian tumors. Using comparative genomic hybridization, we compared cytogenetic changes in borderline ovarian tumors and stage I invasive tumors. The average number of genetic alterations differed significantly between the borderline and the invasive tumors (1.9 and 9.2, respectively). The most common genetic alterations among the borderline tumors were loss of chromosome 17, 20q, and 18p, and gain of 12p13 approximately q23. These changes were also found among the invasive tumors in a similar percentage. In conclusion, we found four distinct cytogenetic alterations that might be early events in serous ovarian tumors, and that might also characterize a subgroup of borderline ovarian tumors that may have the potential to progress and develop malignancy.     

Differential diagnosis of borderline serous and mucinous ovarian tumors

Electron microscopic study of borderline serous and mucinous ovarian tumours was carried out and revealed marked heterogeneity of both types of these tumours. On the basis of the remote results of surgical treatment of the patients the most dangerous subtype from the point of view of its malignancy, the so-called proliferating, tumour with atypical epithelium, was established.     

Morphology of serous borderline ovarian tumors

The paper provides the results of the examination of ovarian serous borderline tumors in 68 patients followed up during different periods (up to 22 years) after surgery. More valuable information on the course and prognosis of the disease will be provided by taking into account both the process stages and structural features of extra-ovarian implants rather than by detecting the foci of initial invasive growth in the primary tumor. Among 4 peritoneal neoplasia types defined by the author, the desmoplastic reaction occurring around the tubal type tumor cells in particular, should be regarded as the most unfavourable type. The author believes that the serous borderline tumor of the ovary is not a separate nosological entity but a step in progressive malignant transformation of mesothelial tubal epithelium similar to definition of well differentiated carcinoma given by the traditional classification.

目的：观察卵巢交界瘤的临床病理学特点,探索肿瘤不同组织学改变的意义。方法：对45例卵巢浆液性和粘液性交界瘤进行回顾性分析,肿瘤分期按国际妇产科联合会（FIGO）标准,Ⅰ期34例,Ⅱ期4例,Ⅲ期7例。结果：45例卵巢浆液性和粘液性交界瘤占同期卵巢上皮恶性肿瘤的25．4％,浆液性同粘液性交界瘤的比为1：1．3,11例生长于卵巢表面的浆液性交界瘤中,9例出现腹膜种植,2例为浸润性种植,7例为非浸润性种植。2例浆液性交界瘤和1例粘液性交界瘤分别于术后5、4和1年复发。33例交界瘤经2－9年随访,按Kaplan-Meier法5年生存率为100％。结论：卵巢浆液性交界瘤预后较好,卵巢表面生长的浆液性交界瘤常伴有腹膜种植。     

Peritoneal serous borderline tumors: report of two cases

Two cases of serous borderline tumors of the peritoneum are reported. These rare tumors may show variable histological features. The lack of peritoneal invasion, which may be difficult to assess, with minimal or no ovarian involvement are major features for the diagnosis. These tumors should be distinguished from other peritoneal neoplasms such as serous carcinomas because of their good prognosis after surgical therapy alone.
