Hormonal activity of epithelial ovarian tumours in post-menopausal women

Concentrations of progesterone and oestradiol in peripheral serum and tumour cyst fluid were measured in 42 post-menopausal women with epithelial ovarian tumours (17 cancer, 6 borderline malignant, 19 benign tumours) and in 19 post-menopausal women without ovarian neoplasms. The hormonal response of the endometrium was assessed, progestogen and oestrogen receptor content in the tumour tissue case recorded, and tumour deoxyribonucleic acid (DNA) ploidy was measured by flow cytometry.

No significant differences were found between the mean serum steroid levels in patients with malignant, borderline or benign tumours, but the mean serum levels of oestradiol in patients with malignant or benign ovarian tumours were higher than those in the controls. Endometrial hormonal activity was seen in 19% of the samples studied. Malignant and benign mucinous epithelial tumours were the types most frequently associated with hormonal activity. Increased levels of sex steroids were seen in the cyst fluid of serous malignant and borderline malignant tumours, while benign tumours were inactive.

The steroid receptor content of the various tumour types did not vary significantly. Ten (59%) out of 17 ovarian carcinomas were found to be aneuploid and 41% diploid as measured by flow cytometry. No significant differences in serum levels of progesterone and oestradiol were found between aneuploid and diploid ovarian carcinomas.

These results contribute to our knowledge of the hormonal activity of epithelial ovarian tumours in post-menopausal women.     

Inhibin expression in ovarian-type stroma in mucinous cystic neoplasms of the pancreas.

Mucinous cystic neoplasms (MCNs) of the pancreas are typically found in middle-aged to elderly women and contain ovarian-type stroma in the cyst wall. Whether the resemblance of this stroma to ovarian stroma is only morphologic or has more functional similarity is still unclear. Estrogen receptors (ER) and progesterone receptors (PR) have been shown to be expressed in a wide variety of tissues and tumors, including the ovarian-type stroma of MCN. Inhibin, on the other hand, has been shown to have a more restricted expression, limited to ovarian sex cord-stromal components and placental cells, and has recently been shown to be expressed in pancreatic MCNs. However, it is still unclear whether this expression is limited to MCNs of the pancreas and whether it has any diagnostic role. Seven cases of MCN (4 mucinous cystadenoma, 2 borderline MCN, and 1 mucinous cystadenocarcinoma with microinvasion), 6 cases of intraductal papillary mucinous tumor, 1 of mucinous cystic tumor of uncertain classification, 2 of mucinous noncystic adenocarcinoma, 4 of serous cystadenoma, and 4 solid pseudopapillary neoplasms were selected for this study. Five cases with normal pancreatic tissue were included as controls. Immunohistochemical stains for alpha-inhibin, ER, and PR were performed on a representative section from each case on formalin-fixed, paraffin-embedded tissue sections using a standard indirect immunoperoxidase method. All cases of MCN were in female patients with an average age of 55.3 years, showing ovarian-type stroma and clusters of alpha-inhibin-positive luteinized theca-like cells. In all these cases, moderate to strong PR positivity was also noted in the ovarian-type stroma, including many of the alpha-inhibin-positive luteinized theca-like cells. ER was expressed in 2 cases. The epithelial cells of MCNs were all negative for ER, PR, and alpha-inhibin staining. Of the other tumors, 4 solid pseudopapillary neoplasms showed positivity for only PR in the tumor cells. The remaining tumors were negative for all markers. In conclusion, the finding of alpha-inhibin positivity in MCN with ovarian-type stroma further supports its similarity to true ovarian stromal tissue and may suggest a role of complex hormonal interaction in the pathogenesis. In addition, its limited expression in MCNs of the pancreas may be diagnostically useful in difficult cases.     

ThinPrep evaluation of fluid samples aspirated from cystic ovarian masses

The cytological evaluation of ovarian cystic fluid using ThinPrep has not been reported. To determine the diagnostic accuracy of ThinPrep cytology in distinguishing between benign and nonbenign ovarian cystic lesions, we examined 65 fluid samples aspirated during intraoperative consultation with subsequent histologic correlation. One ThinPrep slide was prepared from each sample aspirated from surgically removed ovarian cystic masses and reviewed blindly by a panel of three cytopathologists. The parameters used in cytological evaluation were cellularity, cell types, cellular arrangement, and background. Four samples were acellular and excluded from the study. The consensus cytologic diagnoses were compiled for 61 cases which were assigned to one of the following diagnostic categories: negative for malignant cells (40 cases), atypical cytology (13 cases), and suspicious or positive for malignancy (8 cases). Histologic correlation of the cytological benign/negative cases showed that 26/40 (65%) were histologically benign and 14/40 were false-negative (35%, 5 carcinomas and 9 borderline tumors) with 10 of these cases being mucinous tumors. Most false-negative cytologic samples (11/14 or 79%) did not have an epithelial component. Of the 21 cytological nonbenign diagnoses (atypical/suspicious/positive), 15 (71%) were confirmed on histology (10 carcinomas and 5 borderline tumors). However, a nonbenign cytologic diagnosis was rendered in 6 histologically benign cases, including 2 serous cystadenomas, 1 mucinous cystadenoma, 1 serous cystadenofibroma, 1 endometriosis, and 1 corpus luteal cyst. The diagnostic sensitivity by ThinPrep evaluation of ovarian cystic masses is 81% (26/32) for benign and 52% (15/29) for nonbenign lesions. Our results concluded that ThinPrep examination of ovarian cystic fluid is not accurate in distinguishing benign from malignant cysts, given the significant number of false-negative diagnoses. Major contributing factors include sparse cellularity of the fluid samples and mucinous differentiation of the tumors.

Fascin and EMMPRIN expression in primary mucinous tumors of ovary: A tissue microarray study

ObjectivesThe aim of this study was to compare the expressions of fascin and EMMPRIN in primary malignant, borderline and benign mucinous ovarian tumors, and to investigate the relationship of these markers with tumor progression and their applicability to differential diagnosis.Materials and methodsAn immunohistochemical study was performed for fascin and EMMPRIN using the tissue microarray technique. Eighty-one cases were included in the study; there were 37 benign, 25 borderline and 19 malignant primary mucinous ovarian tumors. For each case, a total staining score was determined, consisting of scores for extent of staining and intensity of staining. The cases were allocated to negative, weakly positive and strongly positive staining categories, according to the total staining score.ResultsBoth of the markers were significantly negative in benign tumors as compared with borderline and malignant tumors. There was no significant difference between borderline and malignant groups for both markers. Sixty-eight percent of malignant tumors were stained positive by fascin, while this rate was 40% for borderline mucinous tumors. All malignant tumors were strongly stained positive for EMMPRIN, while this rate was 92% for borderline mucinous tumors. The rest of the cases stained weakly positive. No significant difference in staining score was found between fascin and EMMPRIN expression.ConclusionsIn ovarian primary mucinous tumors, fascin and EMMPRIN may play an important role in tumor progression from benign tumor to carcinoma. In that context, EMMPRIN and fascin expression may have potential application in the differential diagnosis of some diagnostically problematic mucinous ovarian tumors. However, the differential diagnostic applicability of EMMPRIN appears to be more limited than that of fascin due to its wide spectrum of staining in mucinous ovarian tumors.     

Cystadenoma of spermatic cord resembling ovarian serous epithelial tumour of low malignant potential: immunohistochemical study suggesting Müllerian differentiation

A cystic lesion of the spermatic cord resembling an ovarian serous epithelial tumour of low malignant potential or borderline malignancy is reported. Immunohistochemical staining and electronmicroscropic examination suggested epithelial rather than mesothelial differentiation of the cyst lining cells. There was strong positive immunohistochemical staining of cyst lining cells for CA 125, providing evidence for Müllerian differentiation. A flow cytometric analysis of nuclear DNA content revealed a diploid profile.
