  • [Title] Synchronous ovarian endometrioid adenocarcinoma and endocervical mucinous adenocarcinoma.
  • OBJECTIVE: We report a rare case of synchronous cancer consisting of ovarian endometrioid adenocarcinoma and endocervical mucinous adenocarcinoma.
  • Computed tomography showed an 18 x 16 cm right pelvic tumor, with both cystic and solid components, ascites and bilateral massive pleural effusion.
  • Cytology of the pleural effusion showed no malignant cells.
  • Histology showed moderately to poorly differentiated endometrioid adenocarcinoma of the right ovary with extensive lymphovascular permeation, as well as paraaortic and bilateral pelvic lymph node metastases.
  • Extensive tumor thrombi were observed in the lymphovascular channels of the left ovary, bilateral tubes and uterus.
  • The final surgical-pathologic stage of ovarian endometrioid adenocarcinoma was stage IIIc and of endocervical mucinous adenocarcinoma was stage IA1.
  • Adjuvant chemotherapy with carboplatin and paclitaxel was prescribed postoperatively, but the malignancy was not controlled due to lung, brain and vulva metastases.
  • Diagnosis should be based on histologic examination and requires appropriate treatment for both tumors.

  • [Title] Frequent activating mutations of PIK3CA in ovarian clear cell carcinoma.
  • Ovarian clear cell carcinoma (CCC) is one of the most malignant types of ovarian carcinomas, particularly at advanced stages.
  • Unlike the more common type of ovarian cancer, high-grade serous carcinoma, ovarian CCC is often resistant to platinum-based chemotherapy, and therefore an effective treatment for this tumor type at advanced stages is urgently needed.
  • In this study, we analyzed 97 ovarian CCCs for sequence mutations in KRAS, BRAF, PIK3CA, TP53, PTEN, and CTNNB1 as these mutations frequently occur in other major types of ovarian carcinomas.
  • The samples included 18 CCCs for which affinity-purified tumor cells from fresh specimens were available, 69 microdissected tumors from paraffin tissues, and 10 tumor cell lines.
  • These findings demonstrate that ovarian CCCs have a high frequency of activating PIK3CA mutations.
  • We therefore suggest that the use of PIK3CA-targeting drugs may offer a more effective therapeutic approach compared with current chemotherapeutic agents for patients with advanced-stage and recurrent CCC.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Antisense suppression of pygopus2 results in growth arrest of epithelial ovarian cancer.
  • In epithelial ovarian cancer, constitutively active Wnt signaling is restricted to one (endometrioid) tumor subtype.
  • The purpose of this study was to determine the level of expression and growth requirements of human Pygopus2 (hPygo2) protein in epithelial ovarian cancer.
  • EXPERIMENTAL DESIGN: Expression and subcellular localization of hPygo2 was determined in epithelial ovarian cancer cell lines and tumors using Northern blot, immunoblot, and immunofluorescence.
  • Immunohistochemistry was done on 125 archived patient epithelial ovarian cancer tumors representing all epithelial ovarian cancer subtypes.
  • T-cell factor-dependent transcription levels were determined in epithelial ovarian cancer cells using TOPflash/FOPflash in vivo assays.
  • RESULTS: All six epithelial ovarian cancer cell lines and 82% of the patient samples overexpressed nuclear hPygo2 compared with control cells and benign disease.
  • Depletion of hPygo2 by antisense oligonucleotides in both Wnt-active (TOV-112D) and Wnt-inactive serous (OVCAR-3, SKOV-3) and clear cell (TOV-21G) carcinoma cell lines halted growth, assessed using tissue culture, anchorage-independent, and xenograft assays.
  • CONCLUSIONS: hPygo2 is unexpectedly widely expressed in, and required in the absence of, Wnt signaling for malignant growth of epithelial ovarian cancer, the deadliest gynecologic malignancy.
  • These findings strongly suggest that inhibition of hPygo2 may be of therapeutic benefit for treating this disease.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Increase in expression of the copper transporter ATP7A during platinum drug-based treatment is associated with poor survival in ovarian cancer patients.
  • PURPOSE: The Cu efflux transporter ATP7A is overexpressed in some cisplatin-resistant ovarian carcinoma cell lines.
  • We examined the expression of ATP7A in the major normal human organs and in several types of human malignancies and sought to determine whether ATP7A expression changed during treatment of ovarian carcinomas with Pt-containing regimens.
  • EXPERIMENTAL DESIGN: ATP7A expression was quantified by immunohistochemical staining using microarrays containing normal and malignant tissues, and standard sections of 54 paired tumor samples obtained from ovarian carcinoma patients before and after at least two cycles of platinum-based therapy.
  • ATP7A was expressed in some of the most common human malignancies, including prostate (7 of 7), breast (10 of 10), lung (8 of 8), colon (5 of 8), and ovary (6 of 7), as well as in a wide variety of other types of malignancy.
  • ATP7A staining was detected in 28 of 54 ovarian carcinomas before treatment.
  • Patients with increased ATP7A expression after treatment (18 of 54) exhibited poorer actuarial survival (P<0.0057 by log-rank test).
  • Expression of ATP7A either before or after treatment was not associated with other clinical factors.
  • CONCLUSIONS: Although ATP7A is not detectable in most normal tissues it is expressed in a considerable fraction of many common tumor types.
  • Enrichment of the tumor for ATP7A-expressing cells during platinum drug-based treatment of ovarian cancers is associated with poor survival.

  • We evaluated whether tracer FDG uptake, quantified as an SUV by PET in ovarian epithelial tumors, correlates with clinical stage, tumor grade, cell proliferation and glucose metabolism, all of which are biomarkers for response to chemotherapy, prognosis and overall survival in ovarian cancer patients.
  • Seventeen patients suspected of having ovarian cancer by physical examination, tumor marker analysis and anatomic imaging (such as sonography, CT and/or MRI) underwent whole-body FDG-PET within the 2 weeks prior to surgery.
  • Seventeen epithelial ovarian tumor specimens (13 malignant tumors, 5 at stage I, 2 at stage II, 6 at stage III; 2 borderline tumors; and 2 benign lesions) were available for pathologic evaluation.
  • Therefore, glucose consumption, as determined by analysis of SUVs in FDG-PET, may be a noninvasive biomarker for ovarian epithelial tumors.

  • [Title] Immunohistochemical localization of metallothionein in benign and malignant epithelial ovarian tumors.
  • Metallothioneins (MTs) are a group of low-molecular-weight proteins that are overexpressed in a variety of human neoplasms and are related to differentiation and prognosis in some tumor types.
  • This study investigated immunohistochemically detectable metallothionein expression in benign and malignant ovarian surface epithelial tumors of serous, mucinous, and endometrioid types.
  • Of the malignant tumors, MT expression was found in 68% of endometrioid, 56% of mucinous, and 52% of serous neoplasms.
  • The overexpression of MT in malignant as opposed to benign ovarian surface epithelial tumors may suggest a role in tumorigenesis.
  • Whether high MT expression is an independent prognostic factor and increased expression indicates chemotherapy resistance in ovarian cancer, as has been previously suggested, should be determined by further studies.

  • [Title] Ovarian endometrioid adenocarcinoma arising from an endometriotic cyst in a postmenopausal woman under tamoxifen therapy for breast cancer: a case report.
  • BACKGROUND: Ovarian cancer arising from an endometriotic cyst in a postmenopausal woman under tamoxifen therapy is rare.
  • CASE: We herein report the case of a 67-year-old woman with a history of breast cancer, taking tamoxifen citrate 20 mg/day for 4 years, who underwent an operation for left ovarian tumor.
  • The postoperative histological diagnosis was endometrioid adenocarcinoma in an endometriotic cyst with a gradual transition of the degree of cellular atypia noted from typical endometriotic epithelium, to atypical endometriosis, and finally to adenocarcinoma.
  • CONCLUSION: Tamoxifen may cause malignant transformation of endometriosis through atypical endometriosis even in the postmenopausal state.
  • Atypical endometriosis may act as a precancerous lesion in the process of tamoxifen-induced malignant transformation of endometriosis.

  • [Title] Malignant mixed müllerian tumor with malignant neuroectodermal components (teratoid carcinosarcoma) of the ovary: Report of a case with clinicopathologic findings.
  • Malignant mixed müllerian tumor (MMMT) or carcinosarcoma of the female genital tract is a rare neoplasm.
  • Malignant ovarian tumor composed of müllerian epithelial tumor and malignant germ cell tumor is also rare, with most cases composed of endometrioid adenocarcinoma and yolk sac tumor.
  • Ovarian MMMT with malignant neuroectodermal components resembling immature teratoma is extremely rare.
  • The resected tumor measuring over 20 cm in diameter consisted of cystic and solid components and was very fragile.
  • Microscopic examination showed a heterogenous mixed tumor composed of malignant epithelial, malignant mesodermal and malignant neuroectodermal components.
  • There was no tumor immunoreactivity to alpha-fetoprotein, carcinoembryonic antigen, human chorionic gonadotropin, and inhibin.
  • In spite of aggressive combination chemotherapy and three times of laparotomy, the patient died of disease 3 years 10 months after the initial treatment.
  • This quite rare ovarian tumor closely resembled nasopharyngeal tumors described as 'teratoid carcinosarcoma' is biologically aggressive.
  • We report the fourth case of ovarian teratoid carcinosarcoma.
  • Further cases need to be accumulated to make diagnosis and to determine a successful treatment modality.

  • [Title] Expression of glutathione S-transferase pi (GST-pi) in human malignant ovarian tumors.
  • OBJECTIVES: In recent years, glutathione S-transferase pi (GST-pi) has attracted much attention and has been studied as a mechanism of multidrug resistance of tumors to anticancer drugs.
  • In the present study, we immunohistologically measured the expression of GST-pi in tumor tissues using surgical specimens obtained from patients with malignant ovarian tumors.
  • METHODS: Of 137 patients with malignant ovarian tumors treated and managed during a period of 20 years since the establishment of Tsukuba University Hospital, 117 patients were selected as subjects because of the presence of complete data on their clinical courses as well as paraffin blocks preserved in a good condition.
  • Stainability was graded as 0 when GST-pi was completely absent, 1 when less than 20% of tumor cells were stained, 2 when 20--60% were stained, and 3 when more than 60% were stained.
  • RESULTS: When the correlation between stainability and clinical outcomes was analyzed with Kaplan--Meier method, excluding stage Ia cases that did not receive adjuvant chemotherapy at our hospital, significantly better clinical outcomes were observed in the low stainable group, compared with the high stainable group (P<0.01--0.05, Cox--Mantel test, Wilcoxon's test).
  • CONCLUSION: Since the stainability for GST-pi was high in tumors of histological types with strong resistance to anticancer drugs, and better clinical outcomes were observed in cases having a lower stainability score, the expression of GST-pi was thought to play some role in the resistance of malignant ovarian tumors to anticancer drugs.

  • [Title] TP53 and ovarian cancer.
  • Ovarian cancer represents the fourth most frequent type of cancer among females and is the leading cause of death from gynecological cancer in the western world.
  • This review describes gene alterations in ovarian cancer.
  • Specific emphasis is placed on genetic alterations and the prevalence of TP53 (p53) gene alterations in the distinct biological ovarian tumors (benign, borderline, and malignant) and histological subtypes (serous, mucinous, endometrioid, clear cell), as well as in BRCA1-associated hereditary ovarian cancer.
  • Although multi-modality treatment regimens, including cytoreductive surgery and cisplatin-containing combination chemotherapy, have usefully prolonged survival, the overall cure rate of the disease has not changed dramatically.
  • Ovarian cancer is difficult to eradicate completely by surgery and many patients have only a partial response to postoperative chemotherapy and/or many will develop chemotherapy resistance.
  • All these important factors contribute to the poor prognosis of ovarian cancer patients.
  • In this review, the putative prognostic or predictive value of TP53 in ovarian cancer is addressed.

  • [Title] [Differential diagnosis of ovarian metastases].
  • Ovarian metastases comprise 7-10% of all malignant ovarian tumors.
  • The detection of ovarian metastases is difficult because primary ovarian tumors are a morphologically very heterogeneous group, and metastases can simulate an primary ovarian tumor perfectly.
  • A correct diagnosis, however, is most important in order to avoid an unnecessary and ineffective chemotherapy.
  • Therefore, every morphologically unusual ovarian tumor should raise doubts.
  • In addition, mucinous and endometrioid tumors may also be metastatic in nature.

  • [Title] Glypican-3 expression in primary and recurrent ovarian carcinomas.
  • The identification of glypican-3 (GPC3) expression in malignant neoplasms is potentially of interest because GPC3 might represent a therapeutic target.
  • Tissue microarrays containing tissue cylinders from 308 patients with ovarian carcinomas were used for an immunohistochemical study.
  • There were 255 serous, 38 endometrioid, and 15 clear-cell carcinomas included.
  • From 76 patients, paired tissue samples of primary serous ovarian carcinomas and their corresponding recurrences after platinum-based chemotherapy were available.
  • Glypican-3 was expressed in a total of 17.9% of ovarian carcinomas and was strongly associated with the clear-cell histotype (P = 0.0001).
  • Glypican-3 expression was not associated with tumor stage.
  • In conclusion, our data show that GPC3 is observed in a significant fraction of primary and corresponding recurrent ovarian carcinomas.
  • Glypican-3 may therefore represent a potential target for (second-line) therapy in ovarian cancer.

  • [Title] Classification of ovarian carcinomas based on pathology and molecular genetics.
  • Malignant epithelial tumours (carcinomas) are the most common ovarian cancers and the most lethal gynaecological malignancies.
  • Based on light microscopy and molecular genetics, ovarian carcinomas are subdivided into at least five main subtypes that account for over 95% of cases and are inherently different diseases, as indicated by differences in epidemiological and genetic risk factors, precursor lesions, patterns of spread, molecular events during oncogenesis, response to chemotherapy and outcome.
  • For successful subtype-specific treatment, reproducible pathological diagnosis of tumour cell type is critical.
  • Recent investigations have also demonstrated that a significant number of cancers traditionally thought to be primary ovarian tumours (particularly serous, endometrioid and clear cell carcinomas) originate in the fallopian tube and the endometrium and involve the ovary secondarily.
  • In this review we summarise recent advances in the molecular pathology, which have greatly improved our understanding of the biology of ovarian carcinoma and are also relevant to patient management.

  • [Title] In vitro chemoresistance and biomarker profiles are unique for histologic subtypes of epithelial ovarian cancer.
  • OBJECTIVES: To determine whether there is a relationship between histologic subtype of epithelial ovarian cancer and chemoresistance, we evaluated ovarian carcinomas of six histologic subtypes and correlated histology with in vitro drug response.
  • METHODS: In vitro drug response profiles for different histologic subsets of epithelial ovarian carcinomas exposed to standard relevant chemotherapy agents were determined in the Extreme Drug Resistance assay (EDR).
  • RESULTS: Of 5195 referred serial cases of epithelial ovarian cancer, there were 2660 papillary serous, 303 endometrioid, 142 mucinous, 102 clear cell, 952 undifferentiated carcinomas, and 42 tumors of low malignant potential.
  • For the samples as a whole, the incidences of extreme drug resistance to the tested chemotherapeutic agents were cisplatin 10%, carboplatin 16%, cyclophosphamide 16%, doxorubicin 40%, gemcitabine 21%, paclitaxel 22%, and topotecan 13%.
  • Endometrioid tumors were less resistant to cisplatin (10% vs. 6%) and doxorubicin (42% vs. 20%).
  • CONCLUSIONS: We found significant differences in the frequencies of extreme drug resistance to chemotherapeutic agents and biomarker expression among histologic subtypes of epithelial ovarian cancer.

  • [Title] Ovarian endometriosis associated with carcinoma and sarcoma: case report.
  • Endometriosis is a common clinical disorder that shares certain characteristics, metastasis and recurrence, with malignant neoplasms.
  • Most malignant ovarian tumors arising from endometriosis are clear cell carcinoma or endometrioid adenocarcinoma.
  • Few reports exist of sarcoma associated with endometriosis, and even fewer exist of multiple types of malignancies occurring simultaneously.
  • She was then referred to our institution for treatment recommendation.
  • The pathologic findings revealed bilateral endometrioid adenofibroma of low malignant potential, which was associated with endometrioid intraepithelial carcinoma in the left ovary and high-grade sarcoma in the right ovary.
  • The optimal treatment for endometriosis-associated ovarian cancer depends on the type of malignancy; simultaneously occurring multiple tumor types should be treated individually.

  • [Title] Tumor residual after surgical cytoreduction in prediction of clinical outcome in stage IV epithelial ovarian cancer: a Gynecologic Oncology Group Study.
  • PURPOSE: To identify factors predictive of poor prognosis in a similarly treated population of women with stage IV epithelial ovarian cancer (EOC).
  • RESULTS: The median PFS and OS for this group of stage IV ovarian cancer patients was 12 and 29 months, respectively.
  • Multivariate regression analysis revealed that histology, malignant pleural effusion, intraparenchymal liver metastasis, and residual tumor size were significant prognostic variables.
  • Patients with less than 5.0 cm of disease initially and significant disease and/or comorbidities precluding microscopic cytoreduction may be considered for alternative therapeutic options other than primary cytoreduction.

  • [Title] [Clinical analysis of 25 cases of malignant transformation of endometriosis of the ovary].
  • OBJECTIVE: To study clinicopathologic characteristics, treatment and prognostic factors of malignant transformation of endometriosis of the ovary.
  • METHODS: From 1981 to 1999, a total of 25 patients with malignant transformation of endometriosis of the ovary were retrospectively analyzed.
  • Histological type: of the 25 cases, 14 were endometrioid carcinomas, 2 were clear-cell carcinomas, 2 were adenoacanthoma, 1 was serous papillary adenocarcinomas, 6 were mixed epithelium tumor of ovary.
  • The exact area of histologic transition from benign to malignant epithelium was observed in 25 patients.
  • CONCLUSIONS: The exact incidence and prevalence of malignant transformation in endomertriosis is unknown.
  • Radical tumor resection combined with chemotherapy is the main therapeutic approach for malignant transformation of endometriosis of the ovary.

  • [Title] [Advanced ovarian cancer with Sister Mary Joseph's nodule--a case report].
  • A metastatic umbilical tumor,which we call Sister Mary Joseph's nodule (SMJN), is a sign of poor prognosis despite the primary site of malignant tumor.
  • We describe here a patient with an advanced ovarian cancer and SMJN.
  • A 51-year-old woman was referred to our department for evaluation of an umbilical tumor.
  • As a result of systemic examination, the patient was diagnosed as stage IV ovarian cancer and rapidly underwent an optimal operation.
  • Postoperatively, the chemotherapy for advanced ovarian tumors was begun (paclitaxel 180 mg/m(2) and carboplatin AUC 5, 10 courses every 3 weeks).
  • The patient is well without signs of tumor recurrence or metastasis 10 months after the operation.
  • Forty percent of all navel neoplasms are malignant tumors.

  • [Title] Simultaneously detected primary malignant tumors of ovary and endometrium with unusual histology.
  • A case of a mucinous adenocarcinoma of the ovary with a synchronous endometroid tumor of the endometrium with focal features of undifferentiated carcinoma and deep myometrial invasion is reported.
  • A review of the literature revealed that our case is interesting in view of the fact that simultaneous presentation of primary ovarian and endometrial neoplasms is rare and usually related to low-stage ovarian lesions and well-differentiated and superficial endometrial carcinomas in contrast to our case with the focal features of undifferentiated carcinoma and the deep myometrial invasion.
  • The prognosis in most of the cases is surprisingly good even after total abdominal hysterectomy and bilateral oophorectomy alone without adjuvant chemotherapy or irradiation.

  • [Title] Ovarian nonsmall cell neuroendocrine carcinoma: a clinicopathologic and immunohistochemical study of 11 cases.
  • Nonsmall cell neuroendocrine carcinoma (NSCNEC) of the ovary is a rare and aggressive tumor commonly associated with other surface epithelial and germ cell neoplasms.
  • In 8 cases, NSCNEC was associated with other epithelial neoplasms, including mucinous neoplasms of low malignant potential, mucinous carcinoma, endometrioid carcinoma, mixed endometrioid and mucinous carcinoma, and a high-grade carcinoma, not otherwise specified.
  • In 2 cases, the tumor was associated with a mature cystic teratoma; one of them also containing an invasive moderately differentiated adenocarcinoma.
  • A single case was associated with a benign ovarian cyst.
  • NSCNEC represented anywhere from 10% to 90% of the ovarian tumor.
  • Seven patients were treated with total abdominal hysterectomy and bilateral salpingo-oophorectomy followed by chemotherapy.
  • One patient had a bilateral salpingo-oophorectomy with omentectomy and appendectomy followed by chemotherapy; 1 patient had a total abdominal hysterectomy with right salpingo-oophorectomy followed by chemotherapy; one had a bilateral salpingo-oophorectomy followed by chemotherapy, and one had a right salpingo-oophorectomy with appendectomy followed by chemotherapy.
  • In summary, ovarian NSCNEC is an aggressive tumor with a tendency to present at advanced stage and cause death within a mean of 17 months after diagnosis; however, some patients, particularly those with stage I disease and/or those who have received platinum-based therapy, may have a more favorable prognosis.

  • [Title] Role of endometriosis in cancer and tumor development.
  • In spite of these similarities, endometriosis is not considered a malignant disorder.
  • PTEN, a tumor suppressor commonly mutated (50%) in endometrial carcinoma, is found mutated in endometrioid carcinoma of the ovary, but not in other forms of ovarian cancer.
  • A recent study has shown that somatic mutations in the PTEN gene were identified in 20% of endometrioid carcinomas and 20.6% of solitary endometrial cysts, suggesting that inactivation of the PTEN tumor suppressor gene is an early event in the development of ovarian endometrioid carcinoma.
  • In addition to cancerous transformation at the site of endometriosis, there is recent evidence to indicate that having endometriosis itself may increase a woman's risk of developing non-Hodgkin's lymphoma, malignant melanoma, and breast cancer.
