Abstract
The activity of sequentially administered hormonal therapy was investigated over 25 days in 25 patients with epithelial ovarian carcinoma who had estrogen receptor (ERc)-positive tumors. Patients received ethinyl estradiol (EE) (50 micrograms/d) on days 1 to 7 and medroxyprogesterone acetate (MPA) (400 mg/d) on days 8 to 25. Twenty-three patients completed one or more courses of treatment. There were no complete responses (CR). Four partial responses (PR) with durations of 9, 4, 3, and 1 months were seen. Two incomplete responses with durations of 6 and 4 months were also seen. Six patients had stable disease (SD), and 11 patients had progression. The overall response rate was 17% and may represent a modest improvement in response over those in previously published studies conducted with MPA alone. No significant toxic effects were noticed, and some patients reported an improved sense of well-being. However, two patients experienced depression with this treatment. The mean ERc values in responders, patients with SD, and nonresponders were 70.0, 36.7, and 47.9 fmol/mg cytosolic protein, respectively. Future studies of hormonal therapy in patients with ovarian carcinoma should attempt to identify more reliable indices for determining sensitivity to these agents.

Abstract
Metastasis of one tumor to another is an intriguing and rare phenomenon. Lung and breast malignancies are common donor tumors, while renal cell carcinoma and meningioma serve as frequent recipients. We report a case of malignant carcinoid of the ileum with metastasis to adenocarcinoma of the ovary. Histologic examination of the ovary showed a clear dimorphic pattern consisting of uniform polygonal cells arranged in an insular pattern and highly pleomorphic epithelioid cells forming small glands or solid nests. Immunocytochemical studies firmly established the distinct identity of the two tumors.

Abstract
The pattern of cytoplasmic membrane gangliosides and two cellular features which have been reported to be related to the expression of different membrane gangliosides, namely adhesion to solid substrates and susceptibility to the lytic activity of immune effector cells, have been investigated in drug sensitive A2780 human ovarian cancer cells and in two treatment-induced multidrug resistant sublines (A2780-DX1 and A2780-DX3). The total membrane gangliosides content of A2780 sensitive cells was comparable to that of the two multidrug resistant (MDR) sublines, but the acquisition of the MDR phenotype was characterized by an increased expression of the polysialylated gangliosides (particularly the disialoganglioside GDIa) and decreased expression of the monosialoganglioside GM2. The kinetics of cellular adhesion (both to plastic culture dishes and to extracellular matrix coated dishes) were similar in the three cell lines, indicating that the gangliosides profile seems not to be relevant for cell adhesivity to the above mentioned substrates. When human peripheral blood lymphocytes in toto (PBL) and two lymphokine activated (LAK) T cell subpopulations (CD3+4-8- and CD3-16+) were used as effector cells against A2780 (sensitive) and A2780-DX3 (highly resistant) cells, cytolysis of target cells was more efficient against the A2780-DX3 subline, suggesting a possible role of the ganglioside GD1a as a target structure for LAK immunotherapy.

Abstract
A comparative immunocytochemical study was performed on endometriotic epithelial versus endometrial epithelial and normal mesothelial cells in order to obtain further evidence for either the endometrial implantation or mesothelial metaplasia theory. The three cell types could not be distinguished by keratin subtyping, using monoclonal antibodies (MAbs) to keratins 5, 7, 8, 14, 18, and 19. The epithelial markers HMFG-2 and BW 495/36, and a newly developed MAb NEND-3 (against endometrial cells) discriminated between generally negatively reacting mesothelial cells and positively reacting endometrial and endometriotic epithelial cells. The MAb NEND-3 appeared to be specific for endometrial (and endometriotic) epithelial cells since no reactivity with other epithelial cell types was found. Typing with MAbs against ovarian carcinoma related antigens (OV-TL 3, OV-TL 10 and OC 125) did not permit sufficient distinction. The marker profile of cultured endometrial, endometriotic and mesothelial cells confirmed the immunocytochemical findings on frozen sections. Although the data are consistent with the endometrial implantation theory, mesothelial metaplasia can not be excluded with regard to the histogenesis of endometriosis since metaplastic mesothelium may express different antigen markers.

Abstract
The distribution of argyrophil cells in epithelial ovarian tumors was studied in 127 cases. The results showed that not only mucinous tumors and endometrioid tumors contained argyrophil cells, but also some serous tumors expressed argyrophilia. 31% of serous tumors including 40% of serous adenocarcinomas contained variable numbers of argyrophil cells. Argyrophilia has been demonstrated in mucinous tumors, endometrioid tumors and Brenner tumors before. However, this is the first time the presence of argyrophilia in serous tumors has been noticed. Moreover, the argyrophil cells in 5 serous carcinomas showed reactivity with Neuroendocrine (chromogranin A) antibody but not with serotonin. The expression pattern of argyrophilia in the serous tumors was different from that of the mucinous tumors; in the former, argyrophil granules appeared in apical portions or throughout the cytoplasm of single or clustered cells. In addition, the argyrophilia in some serous tumors and endometrioid tumors decreased after diastase digestion. Ultrastructurally, no typical neurosecretory granule was found in the argyrophilic serous tumors. The findings in this study suggest that argyrophilia could be quite frequently found in ovarian epithelial tumors and in itself is not a very specific differential characteristic of carcinoid tumors. The argyrophilia found in a variety of epithelial ovarian tumors might lend additional support to the histogenesis and close relationship between the common epithelial tumors of the ovary.

Abstract
The expression patterns of intermediate filament proteins of primary and metastatic endometrial (n = 18) and ovarian (n = 24) adenocarcinomas were analyzed by immunocytochemistry using a panel of specific antibodies and by gel electrophoresis of cytoskeletal preparations, followed by immunoblotting. All cells of all endometrial adenocarcinomas studied contained the "simple epithelial"-type cytokeratins (CKs) 8, 18, and (mostly) 19, with variable numbers of cells also positive for CK 7 and vimentin. In addition, most of these tumors contained individual cells or groups of cells that were positive for the stratification-related CKs 4, 5, 6, 13, 14, and 17. The latter CKs were often associated with squamous cell foci, but were also found in some single (nonsquamous) tumor cells, indicative of early stages of squamous cell differentiation. Ovarian carcinomas of various histologic types and grades contained predominantly CKs 7, 8, 18, and 19. Serous, endometrioid, and anaplastic tumors, but not mucinous and clear cell tumors, also contained minor amounts of stratification-related CKs in variable combinations, mostly including CK 4. In all tumor types except mucinous tumors, vimentin was consistently detected in variable proportions of tumor cells which, however, were rather low in anaplastic carcinomas. Surprisingly, glial filament protein was detected in a minor proportion (< or = 20%) of tumor cells in seven of 14 serous and endometrioid ovarian carcinomas and in three of 18 endometrial carcinomas. These different intermediate filament expression patterns of müllerian duct-type carcinomas, only partly related to the morphologic appearance of the specific type of tumor, might reflect the multipotentiality of differentiation of müllerian duct-derived epithelia. Cytoskeletal features of potential diagnostic value, especially in metastatic carcinomas, are discussed.

Abstract
The pNR-2/pS2 protein is regulated by oestrogens in breast cancer cell lines. This report describes a systematic survey of pNR-2/pS2 expression in a number of common epithelial tumours. Expression was evaluated immunohistochemically in an archival series using antisera raised against the C-terminus of the pNR-2/pS2 protein. Expression of pNR-2/pS2 by malignant epithelial tumours was widespread. Intense immunohistochemical staining was found in tumour cells in a proportion of pancreatic (6/8), large intestinal (7/12), gastric (9/16) and endometrial (4/12) carcinomas. Positive staining for the pNR-2/pS2 protein was also found in both benign and malignant ovarian epithelial tumours and was very significantly associated with mucinous differentiation (P less than 0.00001). Small numbers of carcinomas of bladder (2/10) and prostate (2/7) showed less intense staining and single examples of cervical carcinoma (1/7) and lung carcinoma (1/19) stained positively. None of the renal carcinomas (0/16) examined stained positively. Positive staining showed no correlation with gender. Although there are reports of oestrogen receptor expression in most of the tumour types considered, the possibility of other regulatory influences must also be considered. The pNR-2/pS2 protein may well have a more general role in human epithelial neoplasia than hitherto realised.

Abstract
We examined samples of tumors of human breast, ovary, and colon of various degrees of malignancy for the expression of p53 protein, using a panel of anti-p53 antibodies and peroxidase immunohistochemistry. Of 66 tumor cases (24 cases of ovarian carcinoma, 23 cases of colon adenocarcinoma, and 19 cases of breast carcinoma), 36 (53%) showed high levels of expression of p53 using a human-specific antibody, and 16 (24%) showed high expression of a mutant form of p53. In the mutant p53-positive breast tumor samples, six (86%) were positive for HER-2/neu reactivity, compared with colon (0/4) and ovarian tumors (1/5). The pattern of p53 intracellular localization and tissue distribution, and the relationship between the expression of mutant p53 and cell differentiation, were also examined; poorly differentiated cells showed either overexpression of p53 or higher levels of mutant p53 in comparison with more normal cells.

Abstract
The relationship between tumour ploidy and qualitative and quantitative histopathology was assessed in a series of 95 ovarian carcinomas. 67% of the tumours were non-diploid (DNA aneuploid). 56% of the early stage (I-II) tumours were non-diploid and 81% of the tumours in advanced (III-IV) stages were aneuploid. Histological grading failed to show a clear relationship between increasing malignancy grade and ploidy. There was a close association between DNA ploidy and nuclear perimeter, area and shortest and longest nuclear diameter: the nuclei of non-diploid tumours were generally larger. Also the number of mitotic figures per square millimeter of epithelium in the microscope image (volume-corrected mitotic index, M/V-index) differed significantly between near-diploid and non-diploid tumours. Discriminant analysis showed that 74% of the learning-set tumours (67% of the test set tumours) could be correctly classified in low-ploidy and high-ploidy categories with morphometric features (nuclear perimeter, M/V-index and volume percentage of epithelium). Characteristic features of non-diploid ovarian tumours--rapid proliferation and large nuclear size--could be assessed with morphometric methods which allowed a relatively large aneuploid tumour group to be distinguished.

Abstract
In the present study, ras oncogene product p21 was analyzed immunohistochemically in rat ovarian tumors induced by 7,12 dimethylbenz (a) anthracene (DMBA). 1) After 28-38 (average 35.6) weeks, the tumors -6 adenomas, 30 adenocarcinomas, 3 sarcomas, one mixed müllerian tumor and 2 epidermal cysts--were produced in the rat ovaries. 2) The p21 positive reactions could be seen in the cytoplasm of the tumor cells. The positive rates were as follows: adenomas 83%, adenocarcinomas 57%, sarcomas 67%, mixed müllerian tumors 0%, epidermal cysts 100%, in which the positive reactions were obtained in squamous cells. Both of the serial-allografted tumor and DMBA-OC-1 were positive. 3) The present study showed that the ras oncogene is not a specific gene in ovarian sarcoma or in other tumors. 4) The present study has suggested that the ras oncogene plays a role in tumor genesis including benign tumors, by showing p21 positive in adenomas and epidermal cysts.

Abstract
Selenium (Se) concentration was determined in 150 samples of serum, 135 samples of hair and 96 samples of ovarian tissue from patients with malignant or benign ovarian tumors and normal subjects. The serum Se level in patients with malignant ovarian tumors was significantly lower than that in patients with benign ovarian tumors and normal subjects. No difference of Se concentrations of hair among different groups was observed. Se level in malignant ovarian tumor tissue was significantly higher than that in benign ovarian tumor tissue and normal ovarian tissue. The low serum Se level in patients with malignant ovarian tumors was probably the result of protective migration of Se from blood to the cancer tissue.

Abstract
Although choroid plexus papillomas (CPP) and primary choroid plexus carcinomas (CPC) are rare neoplasms of the central nervous system, they have been the subject of a number of immunohistochemical studies. To date, no unique or specific marker for these neoplasms has been found, however. Normal choroid plexus is a major site of transthyretin (TTR) synthesis, and recently this protein has been proposed as a possible specific marker of choroid plexus differentiation in tumors. In this study, we performed immunohistochemistry for TTR on 13 choroid plexus tumors (six CPP and seven CPC) and on 23 carcinomas metastatic to the brain, four of which had a papillary architecture. We also included four ovarian teratomas that contained choroid plexus elements. Two of the CPP had diffuse staining for TTR, while the four others stained only focally. Five of the CPC stained only focally and less intensely than the control, while one case was negative. Only one CPC stained as strongly and diffusely as normal choroid plexus. Two of the papillary and six of the nonpapillary metastases had focal staining similar to that seen in the five focally positive CPC. The choroid plexus elements of the ovarian teratomas stained as strongly as the positive control. These findings indicate that TTR immunoreactivity is not restricted to primary choroid plexus tumors. Furthermore, most choroid plexus carcinomas stain only weakly or not at all. This limits the usefulness of TTR immunohistochemistry in the diagnosis of primary choroid plexus neoplasms and in the distinction of CPC from metastatic carcinoma.

Abstract
One hundred five patients with Stage III or IV epithelial ovarian cancer whose disease had persisted or recurred after primary surgery and first-line chemotherapy were given tamoxifen (20 mg orally twice daily) and evaluated for response. Eighteen percent of the patients responded: 10% demonstrated a complete response (CR) and 8% showed a partial response (PR). Thirty-eight percent of the patients had short-term disease stabilization. CR had a median duration of 7.5 months, with the longest lasting 17 months. For patients with PR or stable disease, the median duration of response was 3 months (maximum duration, 9 months). When estrogen receptors of tumor tissue from patients demonstrating CR were evaluated, eight of nine (89%) had elevated estrogen receptor levels. This contrasts with patients who had stable or progressive disease as only 59% of them had measurable estrogen receptors (P = 0.16).

Abstract
OC-125 is a monoclonal antibody raised against tumor cells from a patient with serous cystadenocarcinoma and reacting with an antigen CA-125 on the surface of ovarian epithelial cancer cells. We investigated whether immunohistochemical determination of CA-125 in cell samples from the peritoneal cavity could be used to discriminate between non-specific inflammatory changes in the mesothelium and malignant ovarian tumour cells. Three categories of patients were investigated: patients with disseminated serous or endometrioid ovarian carcinomas, patients with non-specific inflammatory changes in the peritoneal cavity and patients subjected to simple hysterectomy with no pathological changes in the mesothelium. In all cases of ovarian cancer CA-125 positive cells could be detected in the peritoneal fluid; none of the other categories showed positive reaction for CA-125. The results suggest that OC-125 may be a valuable adjunct in differentiating neoplastic from other cells in ascitic fluid from patients with some types of ovarian cancer.

Abstract
Using an immunoradiometric assay, Cathepsin-D (Cath-D) concentrations were measured in the cytosol of 68 normal and neoplastic human ovarian tissues. Cath-D levels were higher in malignant tumours than in normal tissue samples (P less than 0.01) and benign tumours (P less than 0.01). In six out of seven cases, metastatic deposits showed Cath-D concentrations higher than the respective primary tumours. Using 12 of 17 pmols.mg-1 protein as cut-off levels, the Cath-D status (high or low) was not related to any pathological parameter. Moreover, no correlation was found between Cath-D levels and receptors for oestrogen, progesterone and epidermal growth factor. Our results indicate that ovarian tumours produce Cath-D. Further studies are needed to evaluate whether this protein could represent a prognostic factor for this neoplasia.

Abstract
We examined the histologic, immunohistochemical, and clinical features of a series of 23 endometrial, five cervical, and one ovarian carcinosarcomas (malignant mixed müllerian [mesodermal] tumors) and nine associated distant peritoneal metastases. The primary tumors all showed epithelial differentiation (cytokeratin and/or epithelial membrane antigen expression) of the carcinomatous component, while sarcomatous areas showed epithelial differentiation in all but one case. The metastases showed uniform staining for cytokeratin (eight of eight cases) and epithelial membrane antigen (eight of eight cases), including the spindle cell component that was present in four of nine cases. Desmin significantly changed the interpretation of rhabdomyosarcoma differentiation by refuting putative rhabdomyoblasts in two cases and identifying rhabdomyoblasts in two other cases where they were unrecognized on hematoxylineosin staining. S100 protein was positive in all five cases with chondrosarcoma differentiation. Muscle-specific actin and vimentin were positive in the sarcomatous component of all cases and in the carcinomatous component of seven and 10 cases, respectively. After immunostaining, heterologous elements were present in 18 of 29 cases (11 cases of rhabdomyosarcoma, three cases of chondrosarcoma, three cases of mixed rhabdomyosarcoma and chondrosarcoma, and one case of liposarcoma). Only six of 27 patients with follow-up were disease free for 12 months or longer (associated with stage I or II disease, smaller size, no lymphatic invasion in the resection specimen, and no invasion of the outer two thirds of myometrium). Presence and type of heterologous elements, grade of sarcomatous or carcinomatous components, histologic type of carcinomatous component, gross appearance, presence of necrosis, or use of chemotherapy or radiotherapy did not affect outcome. Carcinosarcomas are clinically aggressive distinctive mixed epithelial-stromal neoplasms with histologic and immunohistochemical features that overlap with metaplastic carcinoma in many cases.

Abstract
We describe a case of goblet cell carcinoid of the vermiform appendix, which metastasized to the bilateral ovaries, uterus, vagina and peritoneum three years and four months after appendectomy. The appendiceal tumor showed transmural infiltration of carcinoembryonic antigen-positive goblet cell-type tumor cells, intermingled with a small number of argyrophilic cells immunoreactive for serotonin and chromogranin A. The presence of neurosecretory-type granules was confirmed ultrastructurally in some mucin-negative tumor cells. The pattern of proliferation was typical of carcinoid tumor originating from the lower-most part of the mucosa, and showed lymphatic permeation. The metastatic lesions in the pelvic organs showed either diffuse infiltration of goblet cell-type tumor cells or mucinous cystadenocarcinoma-like features, the latter being evident in the right ovary. No neuroendocrine component was identified in the metastatic deposits. The kinship of appendiceal goblet cell carcinoid to adenocarcinoma is discussed.

Abstract
A prospective study was undertaken to compare flow cytometric (FCM) analysis to conventional cytologic evaluation for the detection of malignant cells in peritoneal fluids (peritoneal lavages and ascitic fluids) from women with gynecologic diseases. The 94 peritoneal fluids analyzed came from 63 cancer patients (with epithelial ovarian carcinomas) and 31 control patients (with benign gynecologic diseases). The FCM DNA histograms were generated using propidium iodide as a DNA fluorochrome. Samples for cytologic analysis were stained with the standard May-Grünwald-Giemsa or Papanicolaou stains. Of the 94 samples, 90 were evaluable cytologically while 70 were suitable for FCM analysis. The sensitivities were 55% for FCM DNA analysis and 80% for cytologic analysis. FCM DNA analysis had a 30% false-positive rate; cytologic analysis produced no false-positive results. These results indicate that there is no advantage in employing FCM analysis instead of conventional cytologic evaluation for the detection of malignant cells in peritoneal fluids from gynecologic cases.

Abstract
A case of ovarian carcinoid tumor of the trabecular type is presented. The small carcinoid tumor was found incidentally in a resected dermoid cyst. Histologically, the tumor was surrounded by a smooth muscle layer with focal stromal invasion. Non-carcinoid papillary mucosa and a few small glands, simulating the mucosa of the fallopian tube and remnant müllerian glands, respectively, were also present adjacent to the carcinoid tumor and enclosed by the same smooth muscle layer. The tumor cells revealed argyrophilia, and were positive for peptide tyrosine tyrosine (PYY) in the cytoplasm and for CEA in part of the luminal surface. This case was considered to be a rare ovarian carcinoid tumor arising from a dermoid cyst, without association of struma ovarii. PYY may be a potential marker for determining the histogenesis of ovarian carcinoid tumors.

Abstract
The metallothionein content of ovarian tumours is considerably higher than that found in normal ovaries (greater than 100-fold differences in mean values, P less than 0.001). There was no difference between the metallothionein content of tumours from patients who had completed chemotherapy, usually with a regimen containing a platinum drug, and tumours from untreated patients. Similarly, the level of metallothionein was not influenced by response to therapy, age, stage, histology, or tumour cell differentiation state. These data do not support the hypothesis that metallothionein content is a major determinant of tumour sensitivity in ovarian cancer.

Abstract
Women with breast cancer have an increased risk of developing primary ovarian tumors. Because a differential diagnosis between primary and metastatic tumors may be difficult in poorly differentiated ovarian neoplasms, breast carcinoma markers may be helpful in establishing the primary site of origin. Gross cystic disease fluid protein-15 (GCDFP-15), a well-known marker of apocrine differentiation, has been reported as a highly specific and sensitive breast carcinoma marker. To evaluate the usefulness of GCDFP-15 as a marker for metastatic breast cancer, we have studied, by the avidin-biotin-peroxidase technique, 14 cases of breast cancer metastatic to the ovary and compared them with 32 primary ovarian tumors and seven cases of ovarian metastases other than breast in origin. Two cases of primary ovarian cancer metastatic to the breast were also included. A strong cytoplasmic immunostaining was found in 10 of 14 cases (71%) of ovarian metastasis from breast carcinoma, and in most cases a characteristic paranuclear staining was noted. All primary ovarian tumors were negative. Ovarian metastases from tumors other than breast and both cases of ovarian carcinoma metastatic to the breast were negative. These results are highly significant (P less than .00001) and demonstrate the value of GCDFP-15 in establishing a primary breast origin among neoplasms of unknown origin involving the ovaries.

Abstract
We describe an ovarian mucinous cystadenocarcinoma with several sarcoma-like mural nodules (SLMN). The distinction between these lesions and foci of anaplastic carcinoma is important because of the poor prognosis of the latter. We have studied the potential value of immunohistochemistry in the differential diagnosis of these two lesions. In contrast to an anaplastic carcinoma, which was largely composed of keratin-positive cells, SLMN were negative or only focally positive. Therefore, in distinguishing SLMN from foci of anaplastic carcinoma, keratin strains may be added to other gross and microscopical differential features, such as size, demarcation, and presence or lack of obvious carcinomatous elements.

Abstract
Recently, hematopoietic growth factors have been implicated in protean nonhematopoietic processes. In the current study, expression of macrophage colony-stimulating factor (M-CSF) and its receptor (the c-fms proto-oncogene) was investigated in 42 samples of gynecologic tissues. There were 15 samples of normal ovarian and uterine tissue or benign conditions of these organs; 11 samples of primary ovarian cancer tissue; seven samples of metastatic ovarian cancer tissue; and nine samples of primary endometrial cancer tissue. Steady state transcript levels were assessed by Northern Blot analysis. Macrophage colony-stimulating factor (M-CSF) expression was not observed in any of the specimens of benign abnormalities or of normal organs; c-fms expression was detected in two of 15 (13%) of these specimens, albeit at very low levels. In contrast, 14 (78%) of 18 ovarian tumor specimens, and five (55%) of nine endometrial tumor specimens expressed M-CSF. Similarly, 16 (89%) of 18 ovarian tumor specimens and six (67%) of nine endometrial tumor specimens expressed c-fms. Most positive malignant tissues (19 [86%] of 22) showed coexpression of M-CSF and c-fms. Of interest, M-CSF and c-fms mRNA were detected in tumor, but not in adjacent normal tissue. Furthermore, M-CSF and c-fms transcripts were produced by all metastatic tumors, including two cases in which the corresponding primary tumor from the same patient was negative. Because M-CSF mediates its effects by binding to its receptor, the increased levels of both these gene products in gynecologic malignancies suggest that an interaction between M-CSF and c-fms may participate in the development of ovarian and endometrial carcinomas and especially in progression to the metastatic state.

Abstract
Primary tumours from 40 patients with epithelial ovarian cancer, treated at St Thomas's Hospital over a 10-year period, were studied for the immunocytochemical expression of the following tumour markers in formalin-fixed paraffin embedded material: carcinoembryonic antigen (CEA), epithelial membrane antigen (EMA), cytokeratin (CAM 5.2), and DD9. An indirect immunoperoxidase staining technique was used. All of the tumours were positive for EMA and CAM 5.2, and 30% of them were positive for both CEA and DD9. The absence of CEA and DD9 may be of value in differentiating between metastatic abdominal adenocarcinomas of ovarian origin and those of gastrointestinal origin, but no indication of prognosis was obtained using these epithelial markers. The strong and widespread staining of all the tumours for EMA suggests that this may be a useful marker for detecting metastatic or recurrent disease by immunoscintigraphy.
