Abstract
Objective Carcinosarcoma of the ovary is a rare pathological type of ovarian cancer that is highly aggressive and occurs most frequently in the female reproductive tract at the site of the uterus. Herein, we explore the clinicopathological features, diagnosis, differential diagnosis, and treatment options for carcinosarcoma of the ovary. Methods We analyzed the clinical data of a case of carcinosarcoma, observed its histological morphology and immunohistochemical characteristics, detected the homologous recombination repair deficiency gene mutation, and reviewed the relevant literature. Results A 76-year-old menopausal woman visited our hospital because of abdominal distension, difficulty in urination, and constipation. Ultrasonography demonstrated abnormalities in the uterus and pelvic cavity, suggesting that the patient should undergo surgery. Immunohistochemical findings of carcinosarcoma of the right ovary were as follows: CK fraction (+), vimentin fraction (+), CK5/6 foci (+), p16 (+), p53 in approximately 70% (+), WT-1 foci (+), ER foci (+), PR part (+), Her-2 (1+), CK7 fraction (+), CK20 foci (+), CD99 fraction (+), CD10 fraction (+), CD56 foci (+), c-kit foci (+), SMA part (+), desmin foci (+), PD-L1 (-), SALL4 (-), OCT3/4 (-), p63 (-), p40 (-), D2-40 (-), inhibin (-), PLAP (-), CD30 (-), and Ki67 hotspot in approximately 80% (+). The patient underwent tumor cytoreduction and adjuvant chemotherapy. Currently, she is being followed up for 16 months and has a good general condition. Conclusion The diagnosis of carcinosarcoma relies on histopathological examination and differentiation of carcinosarcoma from immature teratoma. The current therapeutic regimen for carcinosarcoma is still based on tumor cytoreduction and platinum-containing chemotherapy; research on targeted therapy is still in progress.

Abstract
Gynaecological carcinosarcomas are the most lethal gynaecological malignancies that are often highly resistant to standard chemotherapy. They are composed of both carcinomatous and sarcomatous components and are associated with high rates of metastatic disease. Due to their rarity, molecular studies have been carried out on relatively few tumours, revealing a broad spectrum of heterogeneity. In this review, we have collated the gene mutations, gene expression, epigenetic regulation and protein expression reported by a number of studies on gynaecological carcinosarcomas. Based on these results, we describe potential therapeutics that may demonstrate efficacy and present any pre-clinical studies that have been carried out. We also describe the pre-clinical models currently available for future research to assess the potential of molecularly matched therapies. Interestingly, over-expression of many biomarkers in carcinosarcoma tumours often doesn't correlate with a worse prognosis. Therefore, we propose that profiling the mutational landscape, gene expression, and gene amplification/deletion may better indicate potential treatment strategies and predict response, thus improving outcomes for women with this rare, aggressive disease.

Potent cytotoxic effects of Calomeria amaranthoides on ovarian cancers. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2011; 30:29. [PMID: 21401934 PMCID: PMC3068115 DOI: 10.1186/1756-9966-30-29] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/16/2010] [Accepted: 03/14/2011] [Indexed: 11/17/2022]
Abstract
Background Ovarian cancer remains the leading cause of death from gynaecological malignancy. More than 60% of the patients are presenting the disease in stage III or IV. In spite of combination of chemotherapy and surgery the prognosis stays poor for therapy regimen. Methods The leaves of a plant endemic to Australia, Calomeria amaranthoides, were extracted and then fractionated by column chromatography. In vitro cytotoxicity tests were performed with fractions of the plant extract and later with an isolated compound on ovarian cancer cell lines, as well as normal fibroblasts at concentrations of 1-100 μg/mL (crude extract) and 1-10 μg/mL (compound). Cytotoxicity was measured after 24, 48 and 72 hours by using a non-fluorescent substrate, Alamar blue. In vivo cytotoxicity was tested on ascites, developed in the abdomen of nude mice after inoculation with human OVCAR3 cells intraperitoneally. The rate of change in abdomen size for the mice was determined by linear regression and statistically evaluated for significance by the unpaired t test. Results Two compounds were isolated by chromatographic fractionation and identified by 1H-NMR, 13C-NMR and mass spectrometry analyses, EPD, an α-methylene sesquiterpene lactone of the eremophilanolide subtype, and EPA, an α-methylene carboxylic acid. Cytotoxicity of EPD for normal fibroblasts at all time points IC50 was greater than 10 μg/mL, whereas, for OVCAR3 cells at 48 hours IC50 was 5.3 μg/mL (95% confidence interval 4.3 to 6.5 μg/mL). Both, the crude plant extract as well as EPD killed the cancer cells at a final concentration of 10 μg/mL and 5 μg/mL respectively, while in normal cells only 20% cell killing effect was observed. EPA had no cytotoxic effects. Changes in abdomen size for control versus Cisplatin treated mice were significantly different, P = 0.023, as were control versus EPD treated mice, P = 0.025, whereas, EPD versus Cisplatin treated mice were not significantly different, P = 0.13. Conclusions For the first time both crude plant extract from Calomeria amaranthoides and EPD have been shown to have potent anti-cancer effects against ovarian cancer.

Abstract
OBJECTIVE To study whether interleukin-6 (IL-6) changes the expression of the anti-apoptic Bcl-2 protein in the prevention of cis-diaminedichloroplatinum (II) (CDDP)-induced apoptosis of human ovarian cancer cells. METHODS Comparative studies were performed on 3 ovarian cancer cell lines after 48 hours of exposure to 0.5-50 ng/ml IL-6, 2 micrograms/ml anti-IL-6 monoclonal antibody (anti-IL-6 mAb), 10 microM CDDP, 10 microM CDDP + 0.5-50 ng/ml IL-6, and 10 microM CDDP + 2 micrograms/ml anti-IL-6 mAb. Apoptosis was measured morphologically and by a DNA fragmentation assay. Bcl-2 protein levels were measured by an ELISA. RESULTS An increase in apoptosis was observed for each cell line after 48 hours of exposure to 10 microM CDDP. Although high doses of IL-6 decreased the percentage of apoptotic cells, this cytokine did not change the expression of the Bcl-2 protein. CONCLUSION CDDP-induced apoptosis was negatively controlled by IL-6. However, the anti-apoptic Bcl-2 protein level was not changed by IL-6 in the process of apoptosis in the ovarian cancer cell lines.

Abstract
A cell line was established from a mixed mullerian tumor of the ovary and designated LN1. Histopathologic analysis of the fresh tumor specimen demonstrated a highly aneuploid heterologous tumor comprised of undifferentiated mesodermal components with carcinomatous cells present as a smaller population. Long-term in vitro culture resulted in the establishment of a cell line that exhibits an epithelial-like morphology and expresses epithelial antigens cytokeratin, epithelial membrane antigen, and carcinoma antigen TAG-72. These cells also express mesenchymal intermediate filaments, vimentin, and desmin. Karyotypic analysis revealed a basic triploid pattern with multiple chromosomal abnormalities, most notably an isochromosome of the short arm of five present in three copies. Analysis of oncogene expression revealed that LN1 cells constitutively express mRNA for c-ras, c-erbB2, and p53. The expression of mRNA for cellular oncogenes correlated with the presence of corresponding oncoproteins, p21H-ras, p21K-ras, and p185erB2 and mutant p53 protein. In summary, coexpression of epithelial and mesenchymal antigens by LN1 cells lends support to the hypothesis that epithelial and mesenchymal elements comprising mixed mullerian tumors of the ovary are derived from a common stem cell precursor. Furthermore, this cell line represents a functional in vitro model to evaluate the biologic activities of these unusual and highly aggressive ovarian malignancies.

Abstract
The Rotating-Wall Vessel (RWV) is a novel in vitro cell culture system used to successfully culture a cell line derived from a heterologous mixed mullerian tumor cell of the ovary. Although the original tumor was comprised of both epithelial and mesodermal components, long-term culture in conventional flasks established a cell line from this tumor with homogeneous epitheliallike growth characteristics (1). Cells from Passage 36 were seeded into a Rotating-Wall Vessel containing Cytodex-3 microcarrier beads. Scanning electron micrographs of tumor cells cultured for 32 d in the RWV showed the presence of heterogeneous cell populations organized into three-dimensional tissuelike architecture. Immunocytochemical analysis confirmed the cellular heterogeneity, as demonstrated by expression of both epithelial and mesenchymal antigens. Reverse transcription polymerase chain reaction amplification demonstrated the presence of mRNA for cellular oncogenes HER-2/neu, H-ras, K-ras, and tumor suppressor p53. Thus, there are two advantages to propagation of tissue in the RWV culture system:(a) tissue diversification representing populations present in the original tumor, and (b) the three-dimensional freedom to organize tissues morphologically akin to those observed in vivo. These data indicate that the RWV culture system is suitable for generating large quantities of ovarian tumor cells in vitro that are amenable to immunocytochemical, oncogenic, morphologic characteristics demonstrated in vivo.

Abstract
BACKGROUND Tumors of borderline malignancy are still a controversial subgroup of ovarian neoplasms. The expression of several cell regulatory proteins was studied to characterize the molecular phenotype of these tumors, and to compare them with their benign and malignant counterparts. METHODS Specimens from 22 patients with tumors of borderline malignancy (11 serous and 11 mucinous tumors), 12 patients with benign tumors, and 16 patients with invasive ovarian carcinomas were evaluated for expression of epidermal growth factor receptor (EGFR), HER-2/neu, PTP1B, and p53 by immunohistochemical techniques. RESULTS One or both of the tyrosine kinase growth factor receptors EGFR and HER-2/neu was expressed by 42% of benign, 59% of borderline, and 81% of malignant ovarian tumors. EGFR was expressed in a significantly greater fraction of malignant lesions (69%) than borderline lesions (18%) (P< 0.004). EGFR expression was not observed among the 11 mucinous borderline tumors. HER-2/neu was expressed by 50% of borderline tumors and was not a marker for malignancy. The tyrosine phosphatase PTP1B was expressed by a similar fraction of benign (17%), borderline (27%), and malignant (19%) tumors. The number of cases studied precluded correlation of kinase and phosphatase activity. However, among 12 tumors with PTP1B expression, 9 also expressed EGFR or HER-2/neu. Overexpression of p53 was observed only in malignant serous tumors and was not found in malignant mucinous, borderline, or benign lesions. CONCLUSIONS Either EGFR or HER-2/neu was detected in a majority of borderline cancers. PTP1B was present only in a minority of these cancers. Frankly malignant serous lesions differed from borderline and benign tumors with regard to expression of EGFR and overexpression of p53.

Abstract
Clinical drug resistance poses a major problem in the successful treatment of ovarian cancer. Two genes, MDR1 and MRP, have been found to play a role in the multidrug resistance phenotype of a number of human tumors. Using a sensitive semiquantitative PCR assay we examined 53 primary untreated ovarian tumors for expression of both MDR1 and MRP genes. Approximately one-third of the tumors expressed MDR1 while all the tumors expressed varying levels of the MRP gene.

Abstract
Cancer of the ovary is the leading cause of death from gynecologic malignancy. To understand better these aggressive tumors, the development of in vitro models to study human ovarian cancer is critical. However, the establishment of long-term cell lines has been difficult, due to the generalized poor survival of patient tumor cells grown in primary culture. Satisfactory culture systems for ovarian tumor cells have therefore been limited. To study cellular interactions involved in the growth and differentiation of these tumors, a cell line was established from a mixed müllerian tumor of the ovary. This cell line, designated LN1, was cultured on microcarrier beads in the high aspect rotating-wall vessel. The tumor cells grown in this vessel readily proliferated without a requirement for cocultivation with a supportive cell layer. Evaluation of cellular morphology by phase contrast light microscopy and scanning electron microscopy revealed the presence of three-dimensional multicellular aggregates consisting of multiple cell-coated beads bridged together, as well as scattered aggregates of LN1 cells proliferating as spheroids free in suspension. In contrast to conventional culture systems, culture in the high aspect rotating-wall vessel facilitated the generation of multiple cell types that could be recovered. These results illustrate the ability of this culture system to provide the biological conditions necessary for pluripotent cell growth.

Abstract
To clarify the cellular origin and characteristics of malignant mixed müllerian tumor (MMMT), the authors investigated two cell lines (designated as FU-MMT-1 and FU-MMT-2) established from two patients with heterologous MMMT of the uterus. Both cell lines propagated continuously for 83 and 55 serial passages over 1.5 years, respectively. Morphologically, FU-MMT-2 was a mixture of carcinoma cells and sarcoma cells with predominance of carcinoma cells; FU-MMT-1 only had a sarcomatous element with distinct rhabdomyoblastic differentiation. Immunocytochemically, the sarcoma cells of each cell line expressed, not only myogenic and mesenchymal antigens (desmin, myoglobin, and vimentin), but also epithelial antigens, including epithelial membrane antigen and keratin. The carcinoma cells in FU-MMT-2 were positive for the epithelial antigens and vimentin and negative for desmin and myoglobin. Both lines had abnormal karyotypes; the modal chromosome numbers of FU-MMT-1 and FU-MMT-2 were 47 and 80, respectively. In addition, FU-MMT-1 had trisomy 8, and FU-MMT-2 had complex structural abnormalities. When transplanted into nude mice, FU-MMT-1 reproduced and maintained the characteristics of the original tumor. These cell lines and xenografts appear to provide a useful system for studying the biologic behavior, cytogenetic features, and histogenesis of MMMT. In conclusion, the presence of epithelial antigens in the sarcomatous and carcinomatous elements seemed to support the hypothesis that both elements are derived from a common stem cell.
