浆膜腔积液中转移性腺癌与间皮细胞的病理学研究   总被引:1,自引:0,他引:1  
目的探讨浆膜腔积液中转移性腺癌与反应性间皮细胞增生的鉴别.方法选取胸、腹水转移癌48例及反应性间皮细胞增生30例,采用常规涂片HE染色观察两者形态学特点,并应用免疫细胞化学SP法检测HBME-1、calretinin、E-cadherin、MOC-31和BerEP4的表达.结果腺癌和间皮细胞两者形态各有特点,但是分化好的腺癌和明显增生的间皮细胞仅从常规涂片难以鉴别;免疫细胞化学显示反应性间皮细胞HBME-1和calretinin阳性率为86.7%和76.7%;而腺癌细胞只有少量表达,特异性高达95.8%和100%.MOC-31、E-cadherin和BerEP4对转移性腺癌细胞阳性率为70.8%、77.1%和88.4%,间皮细胞表达很少,特异性分别为90%、93.3%、93%.两者对5种抗体的表现差异显著.结论应用常规涂片和免疫细胞化学相结合的方法对鉴别转移性腺癌和间皮细胞增生有很大的帮助,最好应用一组抗体综合分析判断,HBME-1、Calretinin、E-cadherin、MOC-31及BerEP4是目前非常有效的组合.  相似文献

The clinical introduction of new methods for processing fluid samples and the application of supplementary methods for improving the diagnostic accuracy of the pattern of pleurisy is very important for differential diagnosis. The possibilities of using immunocytochemical assay in the practical work of a clinical diagnostic (cytological) laboratory were studied in 96 patients, including 78 and 18 patients with pleural and ascitic fluids, respectively). A Cytospin-IV centrifuge was used for immunocytochemical assay by the routine procedure. The Streptadivin-biotin LSAB2 and EnVision+ test systems were employed to visualize an antigen/antibody reaction. Diaminobenzidine (DAB) was used as a chromogen. A set of markers, comprising 11 antibodies, was applied to the verification of a neoplasm from serous cavities. Mesothelioma was diagnosed in 65 patients. Epithelial mesothelioma was identified in 62 (95.4%) cases. Mesothelioma cells were positive to vimentin and ceratins, calretinin, mesothelin, and thrombomodulin. In 31 cases, adenogenic carcinoma metastases to the serous cavities were typified by an immunopositive reaction to CEA, Ber-EP4, EMA, and cytokeratins and a negative reaction to calretinin, mesothelin, and thrombomodulin. There was occasionally a positive reaction to CD-15 and vimentin.  相似文献

In some cancer types, certain genes behave as molecular switches, with on and off expression states. These genes tend to define tumor subtypes associated with different treatments and different patient survival. We hypothesized that clinically relevant molecular switch genes exist in epithelial ovarian cancer. To test this hypothesis, we applied a bimodal discovery algorithm to a publicly available ovarian cancer expression microarray data set, GSE9891 [285 tumors: 246 malignant serous (MS), 20 endometrioid (EM), and 18 low malignant potential (LMP) ovarian carcinomas]. Genes with robust bimodal expression patterns were identified across all ovarian tumor types and also within selected subtypes: 73 bimodal genes demonstrated differential expression between LMP versus MS and EM; 22 bimodal genes distinguished MS from EM; and 14 genes had significant association with survival among MS tumors. When these genes were combined into a single survival score, the median survival for patients with a favorable versus unfavorable score was 65 versus 29 months (P < 0.0001, hazard ratio = 0.4221). Two independent data sets [high-grade, advanced-stage serous (n = 53) and advanced-stage (n = 119) ovarian tumors] validated the survival score performance. We conclude that genes with bimodal expression patterns not only define clinically relevant molecular subtypes of ovarian carcinoma but also provide ideal targets for translation into the clinical laboratory.  相似文献

Abstract:
Objective To explore the clinical values of combined detection of serum CA125, CA72-4 and HE4 levels in the early diagnosis of ovarian cancer. Methods The serum levels of CA125, CA72-4 and HE4 in 111 patients with ovarian cancer, 130 patients with benign ovarian disease and 90 healthy female controls were measured by electrochemical luminescence immunoassay (ECLIA) and enzyme-linked immunosorbent assay (ELISA) methods. The diagnostic values of the three markers were analyzed separately and combinedly in ovarian cancer. Results The serum levels of CA125, CA72-4 and HE4 of ovarian cancer patients were significantly higher than those of benign ovarian disease patients and healthy controls(Ps < 0. 01). The positive expression rate of HE4(63.5%) in patients with stage Ⅰ ovarian cancer was significantly higher than that of CA125(55. 8%) and CA72-4 (42. 6%)(Ps < 0. 05) . The combined detection of the three markers may improve the overall accuracy of the early diagnosis of ovarian cancer to 75.8%. The diagnostic sensitivity of serum CA125 was relatively higher in serous cystadenocarcinoma, endometrioid carcinoma and poorly differentiated adenocarcinoma; the diagnostic sensitivity of serum CA72-4 was relatively higher in mucinous cystadenocarcinoma and endometrioid carcinoma; the diagnostic sensitivity of serum HE4 was relatively higher in serous cystadenocarcinoma and endometrioid carcinoma. Conclusion CA125 can serve as the first choice of tumor maker in the diagnosis of ovarian cancer, and the combined detection of serum levels of CA125, CA72-4 and HE4 may increase the diagnostic sensitivity of stage Ⅰ ovarian cancer.  相似文献

Chemokines may control the macrophage infiltrate found in many solid tumors. In human ovarian cancer, in situ hybridization detected mRNA for the macrophage chemokine monocyte chemoattractant protein-1 (MCP-1) in 16/17 serous carcinomas, 4/4 mucinous carcinomas, 2/2 endometrioid carcinomas, and 1/3 borderline tumors. In serous tumors, mRNA expression mainly localized to the epithelial areas, as did immunoreactive MCP-1 protein. In the other tumors, both stromal and epithelial expression were seen. All tumors contained variable numbers of cells positive for the macrophage marker CD68. MCP-1 mRNA was also detected in the stroma of 5/5 normal ovaries. RT-PCR demonstrated mRNA for MCP-1 in 7/7 serous carcinomas and 6/6 ovarian cancer cell lines. MCP-1 protein was detected by ELISA in ascites from patients with ovarian cancer (mean 4.28 ng/ml) and was produced primarily by the cancer cells. Human MCP-1 protein was also detected in culture supernatants from cell lines and in ascites from human ovarian tumor xenografts which induce a peritoneal monocytosis in nude mice. We conclude that the macrophage chemoattractant MCP-1 is produced by epithelial ovarian cancer and that the tumor cells themselves are probably a major source. MCP-1 may contribute to the accumulation of tumor-associated macrophages, which may subsequently influence tumor behavior.  相似文献

Peritoneal mesothelial cell culture and biology.   总被引:2,自引:0,他引:2  
The peritoneal mesothelium is composed of an extensive monolayer of mesothelial cells that lines the body's serous cavity and internal organs and was previously thought to act principally as a protective nonadhesive lubricating surface to facilitate intracoelomic movement. With the introduction of peritoneal dialysis over three decades ago, there has been much interest in the cell biology of peritoneal mesothelial cells. Independent studies have highlighted specific properties of the peritoneal mesothelial cell, including antigen presentation, regenerative properties, clearance of fibrin; synthesis of cytokines, growth factors, and matrix proteins; and secretion of lubricants to protect the tissue from abrasion, adhesion, infection, and tumor dissemination. It is now evident that the mesothelium is not merely a passive membrane but, rather, a dynamic membrane that contributes substantially to the structural, functional, and homeostatic properties of the peritoneum. Since peritoneal mesothelial cells in culture possess immunohistochemical markers identical to mesothelial stem cells, the culture of mesothelial cells offers researchers an essential tool to assess their morphologic, structural, and functional properties. This review will discuss current procedures to isolate peritoneal mesothelial cells from human omental specimens, animal sources, and spent dialysate. Furthermore, the functional and morphologic properties of mesothelial cells are discussed, together with the potential use of mesothelial cell culture in research and clinical applications.  相似文献

The ultrastructure of selected gynecologic neoplasms   总被引:1,自引:0,他引:1  
Several articles have been published recently that discuss the role of electron microscopy in the diagnosis and study of gynecologic neoplasms. It becomes apparent from those works and the review just presented that, although an ultrastructural study is not necessary for reaching a diagnosis of many of these tumors, it may be necessary or supportive in identifying the more poorly differentiated ones. Furthermore, electron microscopy is valuable in providing evidence for the histogenesis of some of these neoplasms. Unfortunately for the pathologist, a certain level of morphologic differentiation (and an absence of metaplasia) in a cell is usually necessary for these goals to be achieved. For example, an adenomatoid tumor (see the article by Dr. Srigley, Mr. Toth, and Mr. Edwards in this issue) of the fallopian tube can readily be accepted as being composed of mesothelial cells, because both the neoplastic cells and normal mesothelial cells have the same highly differentiated features of long, slender microvilli, prominent intercellular junctions, and many microfilaments. On the other hand, there is very little resemblance between the granulosa cells of a granulosa-cell tumor and mature mesothelial cells. Thus, if one of the theories of histogenesis of granulosa cells were correct--namely, that they are derived ultimately from mesothelial lining--the ultrastructural evidence would rest on recognizing a similarity between the two types of cells at an earlier stage of differentiation. The neoplastic granulosa cell has differentiated along a separate, specialized line in which the ultrastructural resemblance to the parent cell is partly, if not completely, lost. Another example of the type of information that electron microscopy can provide is in relation to the common epithelial tumors. There is good evidence that the serous tumors in this group arise from mesothelium, although ultrastructurally their differentiation has veered from a mesothelial direction to one in which the cells have a complement of organelles related to secretory activity. Paradoxically, the mucinous cystic tumors, which have been classified traditionally as tumors of surface epithelial origin, are now thought to be of germ-cell origin in some cases, as examples of monophyletic teratomas. The ultrastructural evidence for this conclusion rests on the presence of anchoring filaments in the microvilli of the neoplastic cells, similar to those of normal intestinal epithelium, and on an admixture of various types of gastrointestinal cells, including those that contain dense-core granules (argentaffin cells).(ABSTRACT TRUNCATED AT 400 WORDS)  相似文献

The total cell count and cell differentiation of the overnight peritoneal dialysis effluent (PDE) was analysed in 34 long-term CAPD patients. The mean percentage and yield of mesothelial cells were 3.1% and 0.17 x 10(6) per PDE. There was a significant lower percentage and yield of mesothelial cells in the PDE of patients with a peritonitis incidence (PI) of more than 2 episodes a year. Independent of dwell time, a positive correlation between the total yield of leucocytes and the yield of mesothelial cells was found. No relation between the amount of phospholipids in the PDE and the yield of mesothelial cells could be shown. Mesothelial cells in the PDE are probably reflecting the turn-over rate of a reactive mesothelium. Whether a low turn-over rate of the mesothelium is causing or is caused by a high PI needs further investigation.  相似文献

Identification of metastatic malignant cells in body fluids and their distinction from reactive mesothelial cells is a common diagnostic problem. Application of the immunoalkaline phosphatase method using epithelial membrane antigen, cytokeratin, vimentin, carcinoembryonic antigen, lysozyme, and leukocyte common antigen (CD 45) is routinely performed in our Hematology Laboratory in conjunction with morphological examination of body fluids. Recently, we found that anti-Leu M5 (CD 11 c), a monoclonal antibody to human monocyte/macrophage, is frequently reactive to mesothelial cells. We then undertook a prospective study, adding anti-CD 11c to the above-listed antibody panel and applying to cytocentrifuge preparations of body fluid. The neoplastic cells in only 2 out of 34 cases (5.9%) with the diagnosis of metastatic carcinomas reacted positively for CD 11c. The neoplastic cells in four cases of malignant lymphoma were non-reactive for CD 11c. In addition, malignant cells on touch preparations of 25 carcinomas were also negative. Mesothelial cells in all 15 cases of reactive effusions and those mesothelial cells present in malignant effusions were positively stained with CD 11c, although the intensity of staining varied in different mesothelial cells of the same cases. We conclude that anti-CD 11c can be considered as a useful adjunct to the differential diagnosis of malignant effusions. © 1993 Wiley-Liss, Inc.  相似文献

BACKGROUNDPrimary ovarian mucinous carcinoma is a rare histologic subtype of epithelial ovarian carcinoma and exhibits considerable morphologic overlap with secondary tumour. It is hard to differentiate primary from metastatic ovarian mucinous carcinoma by morphological and immunohistochemical features. Because of the histologic similarity between primary ovarian mucinous carcinoma and metastatic gastrointestinal carcinoma, it has been hypothesized that ovarian mucinous carcinomas might respond better to non-gynecologic regimens. However, the standard treatment of advanced ovarian mucinous carcinoma has not reached a consensus.CASE SUMMARYA 56-year-old postmenopausal woman presented with repeated pain attacks in the right lower quadrant abdomen, accompanied by diarrhoea, anorexia, and weight loss for about 3 mo. The patient initially misdiagnosed as having gastrointestinal carcinoma because of similar pathological features. Based on the physical examination, tumour markers, imaging tests, and genetic tests, the patient was clinically diagnosed with ovary mucinous adenocarcinoma. Whether gastrointestinal-type chemotherapy or gynecologic chemotherapy was a favourable choice for patients with advanced ovarian mucinous cancer had not been determined. The patient received a chemotherapy regimen based on the histologic characteristics rather than the tumour origin. The patient received nine cycles of FOLFOX and bevacizumab. This was followed by seven cycles of bevacizumab maintenance therapy for 9 mo. Satisfactory therapeutic efficacy was achieved.CONCLUSIONThe genetic analysis might be used in the differential diagnosis of primary ovarian mucinous carcinoma and non-gynecologic mucinous carcinoma. Moreover, primary ovarian mucinous carcinoma patients could benefit from gastrointestinal-type chemotherapy.  相似文献

Prognostic value of cytologic peritoneal washings   总被引:2,自引:0,他引:2  
The following points summarize the important diagnostic and prognostic features of peritoneal cytology. Malignant cells in peritoneal fluid are most often indicative of secondary malignancies with short periods of patient survival except in some early-stage tumors of the female genital tract. Atypical reactive mesothelial cells can simulate malignant cells. Experienced cytologic evaluation is important. Peritoneal cytology is an integral part of the initial staging and follow-up of ovarian cancer. Many researchers feel that peritoneal cytology is important for prognosis in endometrial cancer, and cytologic evaluation is at present a part of some study protocols. There is a low yield of positive peritoneal cytologic findings in patients with early-stage cervical cancer, and cytologic assessment probably plays a small role when other poor prognostic factors are present. Thorough sampling of the peritoneal cavity and careful cytologic preparation are important for optimal diagnosis.  相似文献
