    Ovarian yolk sac tumors (YSTs) usually occur in the young women and have been rarely documented in perimenopausal and postmenopausal women. The different age distribution supposes their complex nomenclature and histogenesis. We report a case of bilateral ovarian epithelial carcinoma with right ovarian YST component in a postmenopausal woman. The patient was treated by surgery and adjuvant combination chemotherapy of taxol and carboplatin for 6 courses and has been clinically free of tumor for 6 months. The correlation between the YST and the epithelial components always confuse us. Ovarian yolk sac tumors are not a discrete entity and represent a multifaceted group of neoplasms. The conjunction of multi antibodies help in differential diagnoses. In addition to a thorough case description, the literature concerning this entity is reviewed and discussed. PMID:25550883

    Malignant transformation of a mature teratoma in the ovary is a rare event, with an approximate rate of only 1-2%. Here, we report an ovarian tumor with a unique combination of epithelial and non-epithelial malignant components, including mature teratoma elements. A 59 year-old postmenopusal woman underwent total hysterectomy and bilateral salpingo-oophorectomy to remove a huge solid mass of the right ovary. The ovarian tumor was 16 × 12 × 4.5 cm in dimensions, composed of red-brown and greyish-white tissue with several cystic areas. Microscopically, atypical cells immunopositive for both CD31 and CD34 formed irregular ectatic vascular patterns with a high MIB-1 labeling index in red-brown areas. In contrast, tubule-cystic and papillary structures were lined by HNF-1β-immunopositive atypical cuboidal and hobnail cells with clear cytoplasm in greyish-white areas. In addition, normal-looking epithelial and stromal components, including mature squamous, cuboidal and ciliated epithelial cells, and adipose tissues, were observed in red-brown areas, suggesting an ovarian tumor combining angiosarcoma, clear cell adenocarcinoma, and mature teratoma features. We could demonstrate identical X-chromosome inactivation patterns among all three components by human androgen receptor gene (HUMARA) assays, pointing to complex inter-relationships regarding their pathogenesis. These observations suggest that a malignant tumor composed of two characteristic phenotypes arose in mature teratoma. PMID:22827762

    Bony metastases from ovarian cancer are rare, tend to affect the axial skeleton and are associated with abdomino-pelvic disease. The median time interval between diagnosis of ovarian carcinoma and presentation of bony metastases is 44 months (1). We describe a rare case of high grade left ovarian serous / endometrioid adenocarcinoma presenting with a pathological right femoral fracture 4 weeks following diagnosis and optimal debulking of the ovarian tumour. Orthopaedic surgeons must be vigilant when planning treatment of fractures presenting in patients with a history of ovarian cancer. PMID:24960734

    We report our experience with prostatic-type tissue in ovarian teratomas, and in particular we highlight a case of prostatic-type adenocarcinoma arising within a mature cystic ovarian teratoma in a 32-yr-old woman. On gross examination, the cyst consisted of typical features of a dermoid cyst. Closer examination revealed a single 1.5-cm solid nodule within the cyst. Microscopically, it was composed of a small cyst-like structure lined by urothelium and to one side glandular and stromal tissue consistent with prostate parenchyma. Within the prostatic-type tissue, there were malignant glands morphologically and immunohistochemically supportive of prostatic-type adenocarcinoma Gleason score 3+3=6. There were also areas consistent with high-grade prostatic intraepithelial neoplasia. Although there are several reports in the literature of benign prostatic-type tissue arising within ovarian as well as testicular teratomas, to our knowledge, prostatic-type adenocarcinoma arising in a mature ovarian teratoma is an extremely rare phenomenon, with only 1 previous report in the literature.

    MicroRNAs (miRNAs) can serve as biomarkers in human cancer. To determine the clinical value of urinary miRNAs for ovarian serous adenocarcinoma, we collected urine samples from 39 ovarian serous adenocarcinoma patients, 26 patients with benign gynecological disease and 30 healthy controls. The miRNA microarray data showed that only miR-30a-5p was upregulated and 37 miRNAs were downregulated in the urine samples of ovarian serous adenocarcinoma patients, when compared to healthy controls, which was confirmed after conducting quantitative PCR. The upregulation of urinary miR-30a-5p was closely associated with early stage of ovarian serous adenocarcinoma as well as lymphatic metastasis. Receiver operator characteristic (ROC) analysis demonstrated the potential use of urinary miR-30a-5p as a diagnostic marker for ovarian serous adenocarcinoma. Furthermore, a lower urine level of miR-30a-5p was found in 20 gastric cancer and 20 colon carcinoma patients when compared to ovarian serous adenocarcinoma, suggesting that the upregulation of urinary miR-30a-5p may be specific for ovarian serous adenocarcinoma. miR-30a-5p was also upregulated in ovarian serous adenocarcinoma tissues and cell lines, while urinary miR-30a-5p from ovarian cancer patients was notably reduced following the surgical removal of ovarian serous adenocarcinoma, suggesting that urinary miR-30a-5p was derived from the ovarian serous adenocarcinoma tissue. Notably, miR-30a-5p was concentrated with exosomes from the ovarian cancer cell supernatant or urine from ovarian serous adenocarcinoma patients, supporting a pathway for excretion into the urine. The results also showed that the knockdown of miR-30a-5p significantly inhibited the proliferation and migration of ovarian cancer cells. In summary, to the best of our knowledge, the present study provided the first evidence of increased miR-30a-5p in the urine of ovarian serous adeno-carcinoma patients, while the inhibition of miR-30a-5p suppressed the

    Ovarian clear cell adenocarcinoma has a relatively poor prognosis among the ovarian cancer subtypes because of its high chemoresistance. Differential diagnosis of clear cell adenocarcinoma from other ovarian surface epithelial tumors is important for its treatment. Napsin A is a known diagnostic marker for lung adenocarcinoma, and expression of napsin A is reported in a certain portion of thyroid and renal carcinomas. However, napsin A expression in ovarian surface epithelial tumors has not previously been examined. In this study, immunohistochemical analysis revealed that in 71 of 86 ovarian clear cell adenocarcinoma patients (83%) and all of the 13 patients with ovarian clear cell adenofibroma, positive napsin A staining was evident. No expression was observed in 30 serous adenocarcinomas, 11 serous adenomas or borderline tumors, 19 endometrioid adenocarcinomas, 22 mucinous adenomas or borderline tumors, 10 mucinous adenocarcinomas, or 3 yolk sac tumors of the ovary. Furthermore, expression of napsin A was not observed in the normal surface epithelium of the ovary, epithelia of the fallopian tubes, squamous epithelium, endocervical epithelium, or the endometrium of the uterus. Therefore, we propose that napsin A is another sensitive and specific marker for distinguishing ovarian clear cell tumors (especially adenocarcinomas) from other ovarian tumors. PMID:24721826

    The presence of cancer stem-like cells (CSCs) has been demonstrated to be associated with tumor metastasis, chemoresistance, and rapid recurrence of various tumors. The impact of CSC-related markers in the metastasis and prognosis of ovarian cancer has not been well established. In this study, the protein expression of musashi-1 and ALDH1 was measured using immunohistochemistry. Results demonstrated that the percentage of positive musashi-1 and ALDH1 expression were significantly higher in ovarian serous adenocarcinomas, mucinous adenocarcinomas and clear cell adenocarcinomas than in cystadenomas and normal tissues. The percentage of positive musashi-1 and ALDH1 expression were significantly lower in patients identified with clinical stage I or II ovarian adenocarcinomas without lymph node metastasis compared to patients with clinical stage III or IV tumors and lymph node metastasis. The expression of musashi-1 and ALDH1 was found to be highly consistent in ovarian adenocarcinomas. Univariate Kaplan-Meier analysis showed a negative correlation between musashi-1 or ALDH1 expression and overall survival. Multivariate Cox regression analysis showed that positive expression of musashi-1 or ALDH1 in ovarian adenocarcinoma was an independent predictor of poor prognosis. Our study suggested that musashi-1 and ALDH1 expression are closely related to metastasis of ovarian adenocarcinoma. The positive expression of musashi-1 and ALDH1 might be a poor-prognostic factor of ovarian adenocarcinoma. PMID:25971681

    Pancreatic adenocarcinoma up-regulated factor (PAUF) expression is elevated in both ovarian tumors and pancreatic adenocarcinoma. However, PAUF expression in ovarian tumors according to histologic subtype and grade has not been investigated. In this study, we examined various clinicopathologic features of 24 patients with mucinous cystadenoma (MCA), 36 with mucinous borderline tumors (MBTs), and 46 with mucinous adenocarcinomas (MACs) according to PAUF expression status assessed using immunohistochemistry. We found that MACs more frequently stained positive for PAUF than did MCAs and MBTs (P < 0.0001). Although there was no significant differences with respect to other clinicopathologic characteristics of MACs according to PAUF expression status, patients with PAUF-weakly positive and PAUF-strongly positive MACs tended to have a shorter overall survival (OS) than those with PAUF-negative MAC, determined using a Kaplan-Meier analysis (P = 0.1885). After adjusting for various clinicopathologic parameters, PAUF positivity of MACs was a significant predictive factor for disease-free survival (DFS) (negative vs. weakly positive: P = 0.045, hazard ratio [HR] = 57.406, 95% confidence interval [CI]: 1.090-3022.596; and negative vs. strongly positive: P = 0.034, HR = 97.890, 95% CI: 1.412-6785.925). In conclusion, PAUF was more frequently expressed in MAC than in its benign and borderline counterparts, and was associated with a poor OS and DFS in MAC patients. Therefore, we suggest that PAUF may be a practical biomarker for histopathological categorization and a prognostic marker for patients with an ovarian mucinous tumor. PMID:25197383

    BACKGROUND In cervical adenocarcinoma, surgical treatment involves bilateral oophorectomy, which affects the long-term quality of life. The aim of our study was to access the incidence of ovarian metastasis in early-stage cervical adenocarcinoma and to suggest an algorithm for the triage of these patients to preserve the ovaries. MATERIAL AND METHODS A total 101 patients with cervical adenocarcinoma who had undergone radical hysterectomy with pelvic lymphadenectomy and bilateral oophorectomy were included in this study. Data on the clinicopathologic characteristics of the cases were collected and low risk factors for ovarian metastasis in early-stage cervical adenocarcinoma were analyzed. RESULTS The ovary metastasis rate of cervical adenocarcinoma in this study was 4.95%, while it is only 2% in stage IB1. Pathological grade, LSVI, lymph node status, tumor size, depth of stromal invasion, and involvement of the junction of the cervix and the body of the uterus were associated with ovarian metastasis, while LSVI, lymph node status, depth of stromal invasion, and involvement of the junction of the cervix and the body of the uterus were associated with ovarian metastasis in stage IB. Multivariate analysis revealed that LVSI and lymph node metastasis were independent risk factors for ovarian metastasis in all stages of cervical adenocarcinoma, but involvement of the junction of the cervix and the body of the uterus was an independent risk factor for ovarian metastasis in stage IB. CONCLUSIONS The incidence of ovarian metastasis in cervical adenocarcinoma is low. Our study suggests that ovarian preservation is safe and feasible in patients with no risk factors for ovarian metastasis. Further prospective studies are warranted. PMID:26852916

    Dermoid cysts are common benign ovarian germ cell neoplasms. Occasionally, one of the mature elements undergoes malignant transformation resulting in the formation of a somatic malignancy; most commonly this is squamous carcinoma. We report a unique case where 2 separate malignancies arose within a dermoid cyst, one a signet ring mucinous adenocarcinoma and the other a pulmonary-type adenocarcinoma. There have been only occasional earlier case reports of a possible pulmonary-type adenocarcinoma arising in a dermoid cyst. In the case we report, the pulmonary-type adenocarcinoma was closely associated with a bronchial structure and exhibited diffuse positive immunohistochemical staining with TTF1, PE10, and napsin A. Molecular studies revealed no evidence of epidermal growth factor receptor mutation, a molecular alteration which may be found in primary pulmonary adenocarcinoma. PMID:23026196

    Epithelial ovarian cancer is an aggressive gynecological malignancy with a high mortality rate. Resistance against chemotherapeutic agents often develops in ovarian cancer patients, contributing to high recurrence rates. The multidrug resistance 1 (MDR1/ABCB1) gene encodes P-glycoprotein, which affects the pharmacokinetic properties of anticancer agents. We previously reported that the Caudal-related homeobox transcription factor CDX2 transcriptionally regulates MDR1 expression in colorectal cancer. CDX2 is a factor that influences cancer cell differentiation, malignancy, and cancer progression. We hypothesized that profiling of CDX2 and MDR1 expression could be an effective strategy for predicting anticancer drug resistance. We studied the expression of these factors in clinical samples from ovarian cancer patients. We found that endogenous MDR1 expression was positively associated with CDX2 expression in ovarian mucinous adenocarcinoma. Using ovarian mucinous adenocarcinoma cell lines, we also observed decreased MDR1 expression following inhibition of CDX2 by RNA interference. In addition, CDX2 overexpression in MN-1 cells, which display low endogenous CDX2, resulted in upregulation of MDR1 expression. CDX2 induced MDR1-dependent resistance to vincristine and paclitaxel, which was reversed by treatment with the MDR1-specific inhibitor verapamil. Our findings show that CDX2 promotes upregulation of MDR1 expression, leading to drug resistance in ovarian mucinous adenocarcinoma. Therefore, our study demonstrates the potential of novel chemotherapy regimens based on CDX2 status and MDR1 expression in ovarian mucinous adenocarcinoma. PMID:27060927

    In this communication, the authors summarize their characterization of eight ovarian adenocarcinoma-derived cell lines for level of neu gene amplification, expression of neu transcripts and protein, and intraperitoneal tumorigenicity in nude mice. Two of the eight cell lines in our study (SKOV3 and YAOVBIX1) exhibited five- to ninefold neu DNA sequence amplification, accompanied by up to 200-fold overexpression of transcripts and protein (p185). Both of these cell lines expressed a major approximately 7.5 kb neu-complementary transcript not previously reported in other neu-positive tumor cell lines. One pair of cell lines (YAOVBIX1 and YAOVBIX3), isolated from a single ovarian carcinoma patient's ascites sample differed dramatically in regard to level of neu gene amplification and expression. Immunohistochemical staining of the primary ovarian tumor from which these two lines were derived demonstrated populations of both neu-positive and neu-negative malignant epithelial cells. Seven of the eight ovarian carcinoma lines produced intra-abdominal tumors after intraperitoneal injection into nude mice, irrespective of level of neu gene expression. This study demonstrates tumor cell heterogeneity with regard to neu gene amplification and expression in an ovarian adenocarcinoma, reveals the overexpression of novel neu-complementary transcripts in two independently isolated ovarian adenocarcinoma cell lines, and suggests that neu gene expression is not required for intraperitoneal tumorigenicity of ovarian carcinoma xenografts in a nude mouse model system.

    Lymphoepithelioma-like carcinoma (LELC), an undifferentiated carcinoma with intense lymphoplasmacytic infiltrates, is commonly reported in the nasopharynx and occasionally in other organs. Pure type of LELC has previously been reported in the gallbladder. Mixed type could be reportable in comparison with other organs. Here we present a case of an 83-year-old man with mixed LELC and adenocarcinoma in the gallbladder. To the best of our knowledge, this is the first case of mixed LELC and adenocarcinoma in the gallbladder. PMID:27621754

    An 11-year-old Quarter Horse mare was presented with ventral edema and pleural effusion, secondary to a disseminated ovarian adenocarcinoma. Bilateral thoracocentesis yielded 30 L of thin, blood-tinged fluid, which was a modified transudate. Cytologic examination of the fluid revealed large atypical cells, suggestive of carcinomatous neoplasia. Similar cells were found in the peritoneal fluid. The mare was euthanatized. Necropsy revealed a 35-cm diameter mass in the cranial mediastinum, ventral to the trachea. The left ovary was 25 cm in diameter and most of the parenchyma was replaced by red or brown friable tissue, containing numerous 1-to 3-mm cysts. Papillary adenocarcinoma of the ovary was diagnosed, based on the appearance and arrangement of tumor cells in the ovary, sublumbar and tracheobronchial lymph nodes, and mediastinal mass. Ovarian neoplasia should be considered in the differential diagnosis of pleural effusion in the horse. PMID:4030465

    Introduction. Nonbacterial thrombotic endocarditis (NBTE) is a rare manifestation of hypercoagulability in patients with malignant neoplasms. Case Report. A fifty-six-year-old woman presented to the emergency service; the clinical workup revealed deep vein thrombosis in right leg and bilateral massive PTE. As the abdominal sections on the spiral CT revealed a giant pelvic mass of ovarian origin, she was referred to our hospital's gynecologic oncology department. She was scheduled for surgery under enoxaparin. She described numbness on one side of her face. Cranial imaging findings revealed acute ischemic cerebral lesions and transesophageal echocardiogram showed vegetation on the aortic cusp. Under anticoagulation treatment, she underwent hysterectomy with bilateral salpingo-oophorectomy and infracolic omentectomy. After tumor resection, her neurological symptoms dissolved with aggressive anticoagulant treatment. Pathology result was synchronous endometrial and ovarian adenocarcinoma. Discussion. NBTE is a rare condition often associated with advanced malignancies. Peripheral embolism and venous thrombosis are complications that have been associated with NBTE due to hypercoagulable state. These disorders could be resistant to routine anticoagulant treatment. In case of a thrombotic complication due to ovarian malignancy, surgical resection of the primary tumor may increase the effect of anticoagulant treatment. PMID:26576308

    Central nervous system involvement by ovarian serous adenocarcinoma is rare. We report a case of a 60-year-old woman that developed brain metastasis as isolated site of relapse 4.5 years after a complete resection and adjuvant chemotherapy for a stage Ic disease. She proceeded to a craniotomy with resection of the lesion and, subsequently, to a whole brain radiotherapy. Nineteen months later, she developed carcinomatous meningitis as isolated site of recurrence. Patient was submitted to intrathecal chemotherapy with methotrexate; however, she died from progressive neurologic involvement disease few weeks later. PMID:25506007

    Sixteen cases of mucinous adenocarcinoma of the cervix that were associated with a mucinous tumor of one or both ovaries are reported. The patients ranged from 25 to 70 (average, 44) years of age; two of them had the Peutz-Jeghers syndrome. Eight patients complained of abdominal swelling; most of the remainder had symptoms of uterine origin. Twelve patients had bilateral and four had unilateral ovarian tumors, which were typically large and cystic. Microscopic examination of most of the ovarian tumors revealed various combinations of benign-appearing, borderline, and carcinomatous mucinous epithelium within the same specimen. Most of the cervical tumors were deeply invasive; 10 of them were of the adenoma malignum type. Although there were varying degrees of uncertainty in individual cases, consideration of several features including the extent and distribution of disease in the abdomen, the comparative histology of the tumors, and the pattern of ovarian involvement suggested that 10 of the ovarian tumors were independent primary tumors, three were metastatic from the cervix, and in three cases the ovaries contained both primary and metastatic tumors.

    A 12-year-old female common mynah ( Acridotheres tristis ) was examined because of dyspnea and coelomic enlargement. Abdominal radiographs revealed hepatomegaly and a coelomic mass of unknown origin. Both brightness mode (2-dimensional; 2D) and 3-dimensional (3D) ultrasonography were performed to identify the origin of the mass. Ultrasonographic findings distinguished the mass from the liver and revealed high vascularization of the mass and a moderate increase in echogenicity of the liver. Three-dimensional ultrasonographic histogram analysis of the mass was performed. The mynah was treated with supportive care but died after 3 days. Histopathologic examination showed ovarian adenocarcinoma, with concurrent mild to moderate hepatopathy. In diagnostic imaging using ultrasound in birds, 3D ultrasonography allows perspective images of the internal organs to be obtained and is potentially superior to 2D ultrasonography in evaluating irregularly shaped objects.

    When compared with other epithelial ovarian cancers, the clinical characteristics of ovarian clear cell adenocarcinoma (CCC) include 1) a higher incidence among Japanese, 2) an association with endometriosis, 3) poor prognosis in advanced stages, and 4) a higher incidence of thrombosis as a complication. We used high resolution comparative genomic hybridization (CGH) to identify somatic copy number alterations (SCNAs) associated with each of these clinical characteristics of CCC. The Human Genome CGH 244A Oligo Microarray was used to examine 144 samples obtained from 120 Japanese, 15 Korean, and nine German patients with CCC. The entire 8q chromosome (minimum corrected p-value: q = 0.0001) and chromosome 20q13.2 including the ZNF217 locus (q = 0.0078) were amplified significantly more in Japanese than in Korean or German samples. This copy number amplification of the ZNF217 gene was confirmed by quantitative real-time polymerase chain reaction (Q-PCR). ZNF217 RNA levels were also higher in Japanese tumor samples than in non-Japanese samples (P = 0.027). Moreover, endometriosis was associated with amplification of EGFR gene (q = 0.047), which was again confirmed by Q-PCR and correlated with EGFR RNA expression. However, no SCNAs were significantly associated with prognosis or thrombosis. These results indicated that there may be an association between CCC and ZNF217 amplification among Japanese patients as well as between endometriosis and EGFR gene amplifications. PMID:25658832

    A 26-year-old unmarried woman with irregular menstruation for 4 years was admitted for an intrauterine space-occupying mass. Pathological examination before surgery showed moderately to poorly differentiated endometrial adenocarcinoma. The patient underwent laparoscopically assisted epifascial panhysterectomy with bilateral salpingo-oophorectomy. Pathological examination of the surgical specimens reported moderately to poorly differentiated endometrial adenocarcinoma and stage II clear cell carcinoma. The patient then received chemotherapy and remained alive without evidence of recurrence. Young women with polycystic ovarian syndrome are at high risk of developing endometrial carcinoma, but concurrent clear cell carcinoma is rare. Careful evaluation before and after treatment are essential to improve the patients prognosis. PMID:27222196

    Only five cases of recurrence of malignant mixed Mullerian tumor (carcinosarcoma) from the ovarian carcinoma have been published in the literature to our knowledge. A 64-year-old woman first underwent a total abdominal hysterectomy and bilateral salpingo-oophorectomy because of pelvic mass. Histological diagnosis was serous papillary carcinoma of the left ovary. After six courses of chemotherapy, CA125 level returned to normal range. However, she had persistent multiple mediastinal and para-aortic lymphadenopathies in spite of additional six courses of chemotherapy. Then she underwent the second operation about 2 years after primary surgery. Multiple excisional biopsies were taken from subcutaneous tissue, over the bowels and the left external iliac artery. The histopathological diagnosis which was confirmed by immunohistochemical study was malignant mixed Mullerian tumor for all metastatic foci. A rare case of ovarian serous papillary carcinoma recurring as malignant mixed Mullerian tumor is reported. PMID:26713165

    Mature ovarian teratomas rarely undergo transformation into malignancy. Carcinomas, mostly squamous cell carcinoma, are the most common malignancy arising in mature cystic teratoma. In the present report we describe a 13-year-old girl who developed a large mass in her ovary. Fine needle biopsy identified intestinal type mucinous adenocarcinoma, which was also identified in the full surgical specimen. Extensive sampling of the surgical specimen also identified areas of mature cystic teratoma. Interestingly, molecular analysis of DNA extracted from various components of the lesion identified KRAS mutation in the carcinoma, borderline mucinous tumor and benign intestinal-type epithelium but not in the epidermal component of the teratoma. To the best of our knowledge this is the first report of KRAS mutation in mucinous carcinoma originating in mature cystic teratoma. We discuss the importance of extensive tissue sampling to differentiate between carcinoma originating in teratoma and metastatic colorectal carcinoma to the ovary. Additionally, the identification of KRAS mutation in the morphologically benign intestinal-type epithelium indicated that it is an early event in the carcinogenic sequence and that the molecular pathway of carcinogenesis in teratoma is similar to that in the carcinogenic process of somatic tissue.

    A 50-year-old female patient was diagnosed with Stage IV ovarian serous adenocarcinoma with multiple lymph node metastases. The CA-125 level normalized after four cycles of neoadjuvant chemotherapy (NACT) using paclitaxel, nedaplatin, and bevacizumab (BEV) before surgery. A positron emission tomography-computed tomography (PET-CT) scan showed significantly reduced bilateral adnexal masses after NACT fluorodeoxyglucose (FDG) metabolism in multiple lymph nodes was inhibited significantly, and the number and sites of metastatic lesions were decreased. The patient underwent optimal cytoreductive surgery. Chemotherapy was continued after surgery and image-guided radiation therapy (IGRT) (40 Gy) was applied for the remaining lymph nodes in the pelvic cavity and cervicothoracic region. No sign of recurrence has been observed in this patient nine months after surgery. The patient achieved a satisfactory outcome and no serious side effects were observed. Therefore, addition of BEV to NACT is a new method for the pre-operative treatment of advanced ovarian cancer. PMID:26189267

    Background Non Small Cell Lung Cancer is a highly heterogeneous tumor. Histologic intratumor heterogeneity could be ‘major’, characterized by a single tumor showing two different histologic types, and ‘minor’, due to at least 2 different growth patterns in the same tumor. Therefore, a morphological heterogeneity could reflect an intratumor molecular heterogeneity. To date, few data are reported in literature about molecular features of the mixed adenocarcinoma. The aim of our study was to assess EGFR-mutations and ALK-rearrangements in different intratumor subtypes and/or growth patterns in a series of mixed adenocarcinomas and adenosquamous carcinomas. Methods 590 Non Small Cell Lung Carcinomas tumor samples were revised in order to select mixed adenocarcinomas with available tumor components. Finally, only 105 mixed adenocarcinomas and 17 adenosquamous carcinomas were included in the study for further analyses. Two TMAs were built selecting the different intratumor histotypes. ALK-rearrangements were detected through FISH and IHC, and EGFR-mutations were detected through IHC and confirmed by RT-PCR. Results 10/122 cases were ALK-rearranged and 7 from those 10 showing an intratumor heterogeneity of the rearrangements. 12/122 cases were EGFR-mutated, uniformly expressing the EGFR-mutated protein in all histologic components. Conclusion Our data suggests that EGFR-mutations is generally homogeneously expressed. On the contrary, ALK-rearrangement showed an intratumor heterogeneity in both mixed adenocarcinomas and adenosquamous carcinomas. The intratumor heterogeneity of ALK-rearrangements could lead to a possible impact on the therapeutic responses and the disease outcomes. PMID:26422230

    Ovarian mucinous tumors with mural nodules are rare. The mural nodules are microscopically divergent neoplasms of varying sizes that may be benign (eg, sarcoma-like and carcinosarcoma-like), or malignant (eg, anaplastic carcinoma and sarcoma). The K-RAS gene mutation in ovarian mucinous neoplasms with mural nodules has not been previously reported. This is a case report of a 25-year-old female diagnosed with ovarian invasive mucinous adenocarcinoma with mural nodule of high-grade sarcoma. The mucinous tumor component demonstrated a K-RAS codon 12/13 mutation (p.G12V, c.35 G>T), whereas the sarcomatous component demonstrated a K-RAS codon 12/13 mutation (p.G12D, c.35 G>A). Although both tumor components revealed a mutation in codon 12 of K-RAS, they were of different nucleotide substitutions, indicating that these 2 tumor components were of different clonal origins. However, the fact that the 2 mutations identified in the tumor components are the most common mutations reported in mucinous tumors of the ovary, raises the possibility that sarcomatous mural nodules simply represent a form of dedifferentiation in mucinous tumors.

    Epithelial ovarian cancer (EOC) consists of 5 major histotypes: high-grade serous carcinoma (HGSC), endometrioid carcinoma (EC), clear cell carcinoma (CCC), mucinous carcinoma (MC), and low-grade serous carcinoma (LGSC). Each can have a broad spectrum of morphologic appearances, and 1 histotype can closely mimic histopathologic features more typical of another. Historically, there has been a relatively high frequency of mixed, defined by 2 or more distinct histotypes present on the basis of routine histopathologic assessment, histotype carcinoma diagnoses (3% to 11%); however, recent immunohistochemical (IHC) studies identifying histotype-specific markers and allowing more refined histotype diagnoses suggest a much lower incidence. We reviewed hematoxylin and eosin-stained slides from 871 cases of EOC and found the frequency of mixed carcinomas to be 1.7% when modern diagnostic criteria are applied. Through international collaboration, we established a cohort totaling 22 mixed EOCs, consisting of 9 EC/CCC, 4 EC/LGSC, 3 HGSC/CCC, 2 CCC/MC, and 4 other combinations. We interrogated the molecular differences between the different components of each case using IHC, gene expression, and hotspot sequencing analyses. IHC data alone suggested that 9 of the 22 cases were not mixed tumors, as they presented a uniform immuno-phenotype throughout, and these cases most probably represent morphologic mimicry and variation within tumors of a single histotype. Synthesis of molecular data further reduces the incidence of mixed carcinomas. On the basis of these results, true mixed carcinomas with both morphologic and molecular support for the presence of >1 histotype within a given tumor represent <1% of EOCs. PMID:26099008

    Cancer stem-like cells (CSCs)/cancer-initiating cells (CICs) are defined as a small population of cancer cells that have high tumorigenicity. Furthermore, CSCs/CICs are resistant to several cancer therapies, and CSCs/CICs are therefore thought to be responsible for cancer recurrence after treatment and distant metastasis. In epithelial ovarian cancer (EOC) cases, disease recurrence after chemotherapy is frequently observed, suggesting ovarian CSCs/CICs are involved. There are four major histological subtypes in EOC, and serous adenocarcinoma and clear cell adenocarcinoma are high-grade malignancies. We therefore analyzed ovarian CSCs/CICs from ovarian carcinoma cell lines (serous adenocarcinoma and clear cell adenocarcinoma) and primary ovarian cancer cells in this study. We isolated ovarian CSCs/CICs as an aldehyde dehydrogenase 1 high (ALDH1high) population from 6 EOC cell lines (3 serous adenocarcinomas and 3 clear cell adenocarcinomas) by the ALDEFLUOR assay. ALDH1high cells showed greater sphere-forming ability, higher tumorigenicity and greater invasive capability, indicating that ovarian CSCs/CICs are enriched in ALDH1high cells. ALDH1high cells could also be isolated from 8 of 11 primary ovarian carcinoma samples. Immunohistochemical staining revealed that higher ALDH1 expression levels in ovary cancer cases are related to poorer prognosis in both serous adenocarcinoma cases and clear cell adenocarcinoma cases. Taken together, the results indicate that ALDH1 is a marker for ovarian CSCs/CICs and that the expression level of ALDH1 might be a novel biomarker for prediction of poor prognosis. PMID:23762304

    The clinico-pathological findings are presented in a case of Peutz-Jeghers syndrome associated with a bilateral mammary invasive ductal carcinoma, a well-differentiated mucinous adenocarcinoma of the cervix and microscopic, bilateral ovarian sex cord tumors with annular tubules. The sex cord tumor with annular tubules was described in 1970 by SCULLY, who recognized its striking association with the Peutz-Jeghers syndrome. Two cases of adenocarcinoma of the cervix and another case of uterine adenocarcinoma of unspecified localization associated with Peutz-Jeghers syndrome were found in the literature. It is possible that women with Peutz-Jeghers syndrome run an increased risk of developing adenocarcinoma of the uterine cervix. PMID:644282

    Hollow cell ball structure is often found in the ascites of adenocarcinoma patients. How to form a hollow cell ball structure was studied in vivo and in vitro, using the human cell lines derived from ovarian and endometrial adenocarcinomas. The hollow cell ball structure was formed by horizontal rotation culture of 1 x 10(7) single-suspended cells for 24 hours or by transplanting 1 x 10(6) single-suspended cells into the peritoneal cavity of nude mouse for 24 hours. At one month after transplantation hemi-cyst and hollow cell ball structure were formed in the outermost layer of the grafted tumor on the intraperitoneal serous membrane in the nude mouse. And also great number of floating hollow cell ball structure in the ascites were observed. These results suggest that mechanisms of formation of hollow cell ball structure found in the ascites; one by cell aggregate of single cells, sometimes inner cells of cell aggregate fall into necrosis or secretes mucus inside and make a hollow cell ball structure and another by the removed as the hollow cell ball structure grown from hemi-cyst on the surface of intraperitoneal grafted tumor.

    Introduction An extremely rare case of mixed squamous cell and glandular papilloma of the lung is reported. The correlation between the radiological and the pathological features as well as the clinical pitfall in making a diagnosis is discussed. Presentation of case An asymptomatic 68-year-old female with a cigarette smoking habit presented with a small nodule in her peripheral lung. A wedge resection was performed though it failed on-site diagnosis which was instead obtained following pathological scrutiny. The postsurgical course was excellent with no recurrence of disease. Discussion A small ground glass nodule gradually enlarged and transformed to a partially solid nodule a year and a half later. This transformation falsely made us suspect an early adenocarcinoma development. Eventually, the extremely rare subtype of pulmonary papilloma, with biphasic glandular and squamous cells, had been demonstrated to obstruct the peripheral bronchiole; and the adjoining alveoli had filled with a large volume of mucus. These pathological features seemed to have constituted the inner solid portion and the marginal ground glass portion respectively in the CT images, mimicking invasive lepidic adenocarcinoma. Conclusion Both pre- and intra-operative diagnoses are difficult mainly because of the rareness of the disease, however, mixed squamous cell and glandular papilloma may be considered in case the presence of primary adenocarcinoma is not validated.

    Adenosquamous carcinoma (ASC) and sarcomatoid carcinoma (SC) of the prostate are rare, but highly aggressive tumors. The occurrence of mixed carcinomas in the prostate is even more rarely reported. The present study reports the case of a 62-year-old male who was diagnosed with prostatic adenocarcinoma accompanied by multiple bone metastases, as shown by a needle biopsy and skeletal computed tomography scan. The patient was treated with hormonal therapy, but thereafter, specimens from a transurethral resection of the prostate (TURP) were found to be composed of three histologically distinct elements: ASC, SC and adenocarcinoma. The level of p53 was evaluated by immunohistochemistry in detail, and it was found that this was significantly increased in the TURP samples compared with the needle biopsy samples. The abnormal level of p53 was likely associated with the prognosis of the patient; the patient succumbed to prostate carcinoma two months after the confirmation of the diagnosis. PMID:25295118

    Introduction. Neuroendocrine carcinoma (NEC) of pancreas is a rare tumor with aggressive progression and poor prognosis. Its coexistence with adenocarcinoma poses significant clinical problems and has not been addressed in the literature. Methods. We describe a case of a 51-year-old male who underwent pancreatoduodenectomy due to pancreatic head tumor 1.5 × 1 × 1.4 cm. Histological examination of the specimen revealed a mixed neoplasm: (1) a well differentiated adenocarcinoma, neoplastic blasts of which are extended focally to the submucosa without invading the muscular layer, and (2) a low differentiated NEC consisting of solid clusters and pagetoid formations. All 18 lymph nodes of the specimen were free of neoplastic disease and the surgical margins of the specimen were tumor-free. No adjuvant treatment was administered and two months after the operation the patient developed liver metastasis. FNA cytology of the hepatic lesions revealed low grade carcinoma with neuroendocrine characteristics. Five lines of chemotherapy were administered: VP + CDDP, paclitaxel + ifosfamide + Mesna + CDDP, Folfox + Avastin, Folfiri + Avastin, and CAV. During his treatment he revealed PD and succumbed to his disease 13 months after the operation. Conclusion. Coexistence of NEC with adenocarcinoma of the pancreas is a very rare entity presenting significant challenges regarding its adjuvant treatment and the treatment of distant relapse. PMID:27610261

    Peutz-Jeghers syndrome is characterized by multiple polyps throughout the gastrointestinal tract in association with mucocutaneous pigmentation. Although Peutz-Jeghers syndrome polyps are hamartomas, frequent association of this syndrome with both gastrointestinal and non-gastrointestinal tumours had led to reassessment of the cancer risk in this hereditary disorder. The most common gynaecological tumors in this syndrome are adenoma malignum of the uterine cervix and ovarian sex cord tumor, particularly sex cord tumor with annular tubules. The question of malignant change in a polyp or of the association of gastro intestinal carcinomas still discuss. The authors report a case of Peutz-Jeghers syndrome in a young patient who developed a colonic adenocarcinoma in a hamartomatous polyp together with an incidentally discovered bilateral malignant sex cord tumours. We discuss its association with certain benign and malignant tumors and the risk of rare complications of these hamartomatous polyps. Although malignant tumors are increasingly reported in association with the Peutz-Jeghers syndrome, to our knowledge, there have been no previous reports of such an association in the literature.

    A disodium phosphonooxymethyl prodrug of the antitumor agent triptolide was prepared from the natural product in three steps (39% yield) and displayed excellent aqueous solubility at pH 7.4 (61 mg/mL) compared to the natural product (17 μg/mL). The estimated shelf life (t90) for hydrolysis of the prodrug at 4 °C and pH 7.4 was found to be two years. In a mouse model of human colon adenocarcinoma (HT-29), the prodrug administered intraperitoneally was effective in reducing or eliminating xenograft tumors at dose levels as low as 0.3 mg/kg when given daily and at 0.9 mg/kg when given less frequently. When given via intraperitoneal and oral routes at daily doses of 0.6 and 0.9 mg/kg, the prodrug was also effective and well tolerated in a mouse model of human ovarian cancer (A2780). PMID:26596892

    Ovarian Cancer (OC) is one of the leading causes of cancer-associated death among women. The underlying biochemical cause of OC proliferation is usually attributed to the over-expression of Chondroitin Sulphate Proteoglycans (CSPGs) wherein the CS-E subgroup plays a major role in tumor cell proliferation by over-expressing vascular endothelial growth factor (VEGF). We hereby hypothesize that by targeting the OC extracellular matrix using a CS-E-specific antibody, GD3G7, we could provide spatial delivery of crosslinkers and anti-VEGF agents to firstly induce in vivo crosslinking and complexation (arresting) of CS-E into a "biogel mass" for efficient and effective detection, detachment and reduction of tumorous tissue, and secondly inhibit angiogenesis in OC. It is further proposed that the antibody-assisted targeted delivery of CS-E crosslinkers can bind to highly anionic CS-E to form a polyelectrolyte complex to inhibit the formation of ovarian tumor spheroids that are responsible for spheroid-induced mesothelial clearance and progression of OC. The hypothesis also describes the potential in vivo "On-The-Spot" CSPG crosslinkers such as sodium trimetaphosphate (physical crosslinker), 1,12-diaminododecane (chemical crosslinker), poly(ethylene glycol) diglycidyl ether (synthetic polymer), and chitosan (natural polyelectrolyte-forming agent). In conclusion, this hypothesis proposes in vivo spatial crosslinking of CSPGs as a potential theranostic intervention strategy for OC-a first in the field of cancer research. PMID:27438831

    A subset of women with uterine cancer exhibiting defective mismatch repair (MMR) proteins and microsatellite instability (MSI) may have Lynch syndrome, which also confers a risk for colorectal cancer and other cancers in the patient and in her family. Screening algorithms based on clinical and pathologic criteria are effective in determining which patients with uterine cancer are most likely to benefit from definitive genetic testing for Lynch syndrome. Ovarian cancer, particularly endometrioid adenocarcinoma, is also associated with Lynch syndrome, although the risk is much smaller than for uterine cancer. This study evaluated whether the morphologic criteria [tumor-infiltrating lymphocytes (TILs), peritumoral lymphocytes (PTLs), dedifferentiated morphology)] currently used to screen uterine cancer for further Lynch syndrome testing can be applied to ovarian cancer. Among 71 patients with pure ovarian endometrioid adenocarcinoma treated at a single institution, 13% had a tumor with TILs, 3% had PTLs, and none had dedifferentiated morphology. Overall, 10% of tumors had abnormal MMR protein status, defined as complete immunohistochemical loss of expression of MLH1, MSH2, MSH6, and/or PMS2. Each of these tumors with abnormal MMR status demonstrated MSI using a polymerase chain reaction-based assay evaluating 5 mononucleotide repeat markers. No relationship was found between patient age, TILs, PTLs, or a spectrum of other morphologic variables and MMR protein status/MSI. Only 1/7 tumors with abnormal MMR/MSI had TILs/PTLs. Among 14 patients who died, 12 (86%) had normal MMR status. Among 7 patients with tumors with abnormal MMR/MSI, 5 (71%) were alive without disease. Concurrent uterine tumor was present in 5/7 patients whose ovarian tumor had abnormal MMR/MSI. This study suggests that the morphologic criteria used to screen patients with uterine cancer for further Lynch syndrome testing are not applicable in patients with ovarian cancer. Although abnormal MMR/MSI did

    A recent exome-sequencing study revealed prevalent mitogen-activated protein kinase 1 (MAPK1) p.E322K mutation in cervical carcinoma. It remains largely unknown whether ovarian carcinomas also harbor MAPK1 mutations. As paralogous gene mutations co‑occur frequently in human malignancies, we analyzed here a total of 263 ovarian carcinomas for the presence of MAPK1 and paralogous MAPK3 mutations by DNA sequencing. A previously unreported MAPK1 p.D321N somatic mutation was identified in 2 out of 18 (11.1%) ovarian mixed germ cell tumors, while no other MAPK1 or MAPK3 mutation was detected in our samples. Of note, OCC‑115, the MAPK1‑mutated sample with bilateral cancerous ovaries affected, harbored MAPK1 mutation in the right ovary while retained the left ovary intact, implicating that the genetic alterations underlying ovarian mixed germ cell tumor may be different, even in patients with similar genetic backgrounds and tumor microenvironments. The results of evolutionary conservation and protein structure modeling analysis implicated that MAPK1 p.D321N mutation may be pathogenic. Additionally, mutations in protein phosphatase 2 regulatory subunit α (PPP2R1A), ring finger protein 43 (RNF43), DNA directed polymerase ε (POLE1), ribonuclease type III (DICER1), CCCTC‑binding factor (CTCF), ribosomal protein L22 (RPL22), DNA methyltransferase 3α (DNMT3A), transformation/transcription domain‑associated protein (TRRAP), isocitrate dehydrogenase (IDH)1 and IDH2 were not detected in ovarian mixed germ cell tumors, implicating these genetic alterations may be not associated with MAPK1 mutation in the development of this malignancy. The present study identified a previously unreported MAPK1 mutation in ovarian mixed germ cell tumors for the first time, and this mutation may be actively involved in the tumorigenesis of this disease.

    Mixed lineage kinase 3 (MLK3) is a mitogen-activated protein kinase kinase kinase (MAP3K) that activates MAPK signaling pathways and regulates cellular responses such as proliferation, migration and apoptosis. Here we report high levels of total and phospho-MLK3 in ovarian cancer cell lines in comparison to immortalized nontumorigenic ovarian epithelial cell lines. Using small interfering RNA (siRNA)-mediated gene silencing, we determined that MLK3 is required for the invasion of SKOV3 and HEY1B ovarian cancer cells. Furthermore, mlk3 silencing substantially reduced matrix metalloproteinase (MMP)-1, -2, -9 and -12 gene expression and MMP-2 and -9 activities in SKOV3 and HEY1B ovarian cancer cells. MMP-1, -2, -9 and-12 expression, and MLK3-induced activation of MMP-2 and MMP-9 requires both extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK) activities. In addition, inhibition of activator protein-1 (AP-1) reduced MMP-1, MMP-9 and MMP-12 gene expression. Collectively, these findings establish MLK3 as an important regulator of MMP expression and invasion in ovarian cancer cells. -- Highlights: Black-Right-Pointing-Pointer Ovarian cancer cell lines have high levels of total and phosphorylated MLK3. Black-Right-Pointing-Pointer MLK3 is required for MMP expression and activity in ovarian cancer cells. Black-Right-Pointing-Pointer MLK3 is required for invasion of SKOV3 and HEY1B ovarian cancer cells. Black-Right-Pointing-Pointer MLK3-dependent regulation of MMP-2 and MMP-9 activities requires ERK and JNK.

    Background The molecular biology and cellular origins of mixed type endometrial carcinomas (MT-ECs) are poorly understood, and a Type II component of 10 percent or less may confer poorer prognoses. Methodology/Principal Findings We studied 10 cases of MT-EC (containing endometrioid and serous differentiation), 5 pure low-grade endometrioid adenocarcinoma (EAC) and 5 pure uterine serous carcinoma (USC). Endometrioid and serous components of the MT-ECs were macrodissected and the expression of 60 candidate genes compared between MT-EC, pure USC and pure EAC. We found that four genes were differentially expressed when MT-ECs were compared to pure low-grade EAC: CDKN2A (P = 0.006), H19 (P = 0.010), HOMER2 (P = 0.009) and TNNT1 (P = 0.006). Also while we found that even though MT-ECs closely resembled the molecular profiles of pure USCs, they also exhibit lower expression of PAX8 compared to all pure cases combined (P = 0.035). Conclusion Our data suggest that MT-EC exhibits the closest molecular and epidemiological similarities to pure USC and supports clinical observations that suggest patients with MT-EC should receive the same treatment as patients with pure serous carcinoma. Novel specific markers of MT-EC could be of diagnostic utility and could represent novel therapeutic targets in the future. PMID:26132201

    AIM: To discriminate between adenocarcinomas that are primary to the ovary and metastatic to the ovary, especially of colonic and breast origin, by immunohistochemistry, using stepwise discriminant analysis or a decision tree. METHODS: 312 routinely processed, formalin fixed tissue specimens were used. The tumours were divided into a learning set (n = 159), composed of primary tumours of ovary, breast, and colon, and a test set, comprising 134 metastases from these sites and an additional 19 primary ovarian carcinomas. The immunohistochemical panel was composed of antibodies against cytokeratin 7 (CK7) and 20 (CK20), CA125, vimentin, carcinoembryonic antigen (CEA), gross cystic disease fluid protein-15 (GCDFP-15), and the oestrogen receptor (ER). The staining results of the tumours were expressed as the product of the staining intensity and the percentage of positive tumour cells. Analyses were first performed on the learning set and then evaluated on the test set. RESULTS: Although the immunostaining patterns showed a considerable overlap between the three types of adenocarcinoma, the breast carcinomas were typically positive for GCDFP-15 and often for ER, and negative for vimentin. Ovarian carcinomas were always positive for CK7 and to a lesser extent for CA125. Colonic carcinomas showed prominent positivity for CEA and CK20, while no staining was seen for ER and vimentin. In discriminant analysis, six antibodies (alpha CK7, alpha CK20, alpha CA125, alpha CEA, alpha ER, and alpha GCDFP-15) appeared to be necessary for optimal classification: 89% of the learning set and 82% of the test set were classified correctly. In the decision tree, only four antibodies (alpha CK7, alpha CEA, alpha ER, and alpha GCDFP-15) were used to obtain a correct classification score of 89% for the learning set and 84% for the test set. CONCLUSIONS: Using a semiquantitative assessment of the immunostaining results by a restricted panel of six antibodies with stepwise discriminant

    Mixed germ cell tumors of the ovary have rarely been reported in veterinary species. A 3-year-old intact female Labrador Retriever dog was presented for lethargy, abdominal distention, and a midabdominal mass. An exploratory laparotomy revealed a large (23 cm in diameter) left ovarian tumor and multiple small (2-3 cm in diameter) pale tan masses on the peritoneum and abdominal surface of the diaphragm. Histological examination of the left ovary revealed a mixed germ cell tumor with a yolk sac component with rare Schiller-Duval bodies and a teratomatous component comprised primarily of neural differentiation. The abdominal metastases were solely comprised of the yolk sac component. The yolk sac component was diffusely immunopositive for cytokeratin with scattered cells reactive for α-fetoprotein and placental alkaline phosphatase. Within the teratomatous component, the neuropil was diffusely immunopositive for S100, neuron-specific enolase, and neurofilaments with a few glial fibrillary acidic protein immunopositive cells. Ovarian germ cell tumors may be pure and consist of only 1 germ cell element or may be mixed and include more than 1 germ cell element, such as teratoma and yolk sac tumor. PMID:23604259

    Introduction: Malignant Mixed Mullerian Tumor (MMMT) is a very rare tumor, accounting for less than 1% of all ovarian cancers. Case Presentation: We present a 64-year-old woman with stage III MMMT of ovary that was treated with platinum-based chemotherapy after optimal cytoreductive surgery. After 25 months of being disease free, she had a pelvic recurrence and a good response to chemoradiotherapy. Conclusions: Optimal cytoreductive surgery and chemotherapy may be the best treatment in MMMT but more discussion and experiences are needed regarding the effectiveness of radiotherapy.

    Mixed adenoneuroendocrine carcinomas, spindle cell carcinomas, and clear cell carcinomas are all rare tumors in the biliary tract. We present the first case, to our knowledge, of an extrahepatic bile duct carcinoma composed of all three types. A 65-year-old man with prior cholecystectomy presented with painless jaundice, vomiting, and weight loss. CA19-9 and alpha-fetoprotein (AFP) were elevated. Cholangioscopy revealed a friable mass extending from the middle of the common bile duct to the common hepatic duct. A bile duct excision was performed. Gross examination revealed a 3.6 cm intraluminal polypoid tumor. Microscopically, the tumor had foci of conventional adenocarcinoma (CK7-positive and CA19-9-postive) surrounded by malignant-appearing spindle cells that were positive for cytokeratins and vimentin. Additionally, there were separate areas of large cell neuroendocrine carcinoma (LCNEC). Foci of clear cell carcinoma merged into both the LCNEC and the adenocarcinoma. Tumor invaded through the bile duct wall with extensive perineural and vascular invasion. Circumferential margins were positive. The patient's poor performance status precluded adjuvant therapy and he died with recurrent and metastatic disease 5 months after surgery. This is consistent with the reported poor survival rates of biliary mixed adenoneuroendocrine carcinomas. PMID:24804133

    Background: This research was conducted to introduce a patient with rare ovarian mixed germ cell tumor, presented as molar pregnancy. Case Presentation: The patient was a 16 year old woman admitted with diagnosis of molar pregnancy. Abdominal enlargement was the only complaint. She had a large pelvic mass in physical examination. The first diagnosis was molar pregnancy due to previous ultrasonic reports and positive βeta HCG. Urine pregnancy test was positive. As suction curettage was performed for her, surprisingly, the size of uterus was normal and no molar tissue was found in pathologic examination. At intraoperative ultrasound exam, an extra-uterine heterogeneous mass was found. Extra-uterine mass was confirmed by CT and MRI done after suction curettage. Mixed germ cell tumor was confirmed by histological examination after laparatomy and removing tumoral mass. Finally, she received Bleomycin, Etoposide and Cisplatin (BEP) regimen in four courses and Vincristine, Actinomycin D (Dactinomycin) and Cyclophosphamide (VAC) regimen in two courses and Diphereline for saving the other ovary. Conclusion: Some young patients misinterpret the early symptoms of an ovarian neoplasm as those of pregnancy which can lead to a delay in the diagnosis. PMID:27141469

    Ovarian Cancer (OC) is one of the leading causes of cancer-associated death among women. The underlying biochemical cause of OC proliferation is usually attributed to the over-expression of Chondroitin Sulphate Proteoglycans (CSPGs) wherein the CS-E subgroup plays a major role in tumor cell proliferation by over-expressing vascular endothelial growth factor (VEGF). We hereby hypothesize that by targeting the OC extracellular matrix using a CS-E-specific antibody, GD3G7, we could provide spatial delivery of crosslinkers and anti-VEGF agents to firstly induce in vivo crosslinking and complexation (arresting) of CS-E into a “biogel mass” for efficient and effective detection, detachment and reduction of tumorous tissue, and secondly inhibit angiogenesis in OC. It is further proposed that the antibody-assisted targeted delivery of CS-E crosslinkers can bind to highly anionic CS-E to form a polyelectrolyte complex to inhibit the formation of ovarian tumor spheroids that are responsible for spheroid-induced mesothelial clearance and progression of OC. The hypothesis also describes the potential in vivo “On-The-Spot” CSPG crosslinkers such as sodium trimetaphosphate (physical crosslinker), 1,12-diaminododecane (chemical crosslinker), poly(ethylene glycol) diglycidyl ether (synthetic polymer), and chitosan (natural polyelectrolyte-forming agent). In conclusion, this hypothesis proposes in vivo spatial crosslinking of CSPGs as a potential theranostic intervention strategy for OC—a first in the field of cancer research. PMID:27438831

    Malignant germ cell tumors of the ovary are very rare and account for about 2-5% of all ovarian tumors of germ origin. Most patients are adolescent and young women, approximately two-thirds of them are under 20 years of age, occasionally in postmenopausal women. But clear cell carcinoma usually occurs in older patients (median age: 57-year old), and closely related with endometriosis. Here we report a case of a 55-year old woman with right ovarian mass that discovered by B ultrasonic. Her serum levels of human chorionic gonadotropin (hCG) and α-fetoprotein (AFP) were elevated. Pathological examination revealed the tumor to be a mixed germ cell tumor (yolk sac tumor, embryonal carcinoma and mature teratoma) with clear cell carcinoma in a background of endometriosis. Immunohistochemical staining showed SALL4 and PLAP were positive in germ cell tumor area, hCG, CD30 and OCT4 were positive in epithelial-like cells and giant synctiotrophoblastic cells, AFP, AAT, CD117 and Glyp3 were positive in yolk sac component, EMA and CK7 were positive in clear cell carcinoma, CD10 was positive in endometrial cells of endometriotic area. She was treated with surgery followed by seven courses of chemotherapy. She is well and serum levels of hCG and AFP have been decreased to normal levels. PMID:25674278

    Thirty-three patients with advanced-stage ovarian adenocarcinomas, with no prior chemotherapy, were treated with weekly cisplatin (DDP) for four courses followed by five monthly courses of one of two randomly assigned multidrug combinations. These combinations were high-dose methotrexate-leucovorin plus cyclophosphamide (MECY) or cyclophosphamide, hexamethylmelamine, doxorubicin, and DDP (CHAD). Patients with no clinically measurable disease after 6 months of therapy were evaluated by laparoscopy. In the absence of disease progression at the time of the laparoscopy the study design called for a repeat cycle of four weekly DDP courses and another five monthly courses of the assigned multidrug combination. All patients with no evidence of disease after 1 year of treatment had a second-look laparoscopy which, if negative, was followed by a second-look laparotomy. This report includes all of the consecutively entered patients observed for a minimum of 1 year or to death. DDP-MECY and DDP-CHAD were similarly active for overall response rates and complete response rates according to laparoscopic criteria. However, DDP-MECY had a statistically significantly lower relapse rate (P less than 0.02) and a statistically significantly higher negative second-look laparotomy rate than did DDP-CHAD. Using all entered patients, with no exclusions from analysis, eight of 17 patients (47%) treated with DDP-MECY had negative second-looks after 1 year of treatment. This compares with one of 16 (6%) negative second-looks in patients treated with DDP-CHAD (P less than 0.02). The high negative second-look rate with DDP-MECY is exciting. Positive cytologic washings at the 6-month laparoscopic evaluation were highly predictive that residual disease would be found at the 1-year second-look surgery. Only one patient with positive peritoneal cytology after 6 months of treatment was found to have a negative second-look after 1 year of therapy. PMID:6439408

    In the following study, extremely low frequency electromagnetic fields (EL-EMF) radiation was used to restore sensitivity in the cisplatin-resistant A2780 ovarian cancer cells. For this purpose A2780 cells were treated with different doses of cisplatin and EL-EMF (50 Hz, 200 gauss, and 2 h) alone. Cytotoxicity was the measurement using MTT assay. After calculating IC50 for cisplatin (90 µg/ml) a lower concentration from IC50 (30 and 60 µg/ml) was used to be combined with EL-EMF. We compare the effects of each cisplatin, EL-EMF and combination groups using acridine orange-propidium iodide (AO/PI) and DAPI staining, caspase 3/9 activation assay and Annexin/PI assay. We also assessed changes in P53 and Matrix metalloproteinases 2 (MMPs) gene expression with semi-quantitative RT-PCR. Results indicated an EL-EMF-dependent proliferative decrease which was found <10 %, and occurred independently of cisplatin. The decreased proliferation rate for 30 and 60 µg/ml cisplatin was about 20 and 40 %, respectively, while for synergistic groups 30 and 60 µg/ml cisplatin with 2 h EL-EMF exposer, showed 47 and 71 % decrease in viability in rats. DAPI staining indicated that chromatin break down significantly increased in synergistic groups. Acridine orange staining also confirmed MTT assay results. Caspase activity significantly increased in the combined groups. Semi-quantitative RT-PCR showed that in synergistic groups of cisplatin and EL-EMF, expression of P53 was increased but the expression level of MPP-2 gene decreased. Results from this study showed that changes generated by the non-invasive EL-EMF can make resistant cells sensitive to cisplatin. PMID:26370097

    2016-01-01

    Malignant Mixed Mullerian Tumour of the Ovary (OMMMT), also referred to as carcinosarcoma is a very rare tumour accounting for less than 1% of all ovarian cancers. Due to the rarity of OMMMT, little is known about the disease course and outcome of women with these tumours. It is important to evaluate because of its aggressive behaviour with extremely unfavourable prognosis. These tumours are composed of both malignant epithelial and mesenchymal elements. Current data in the literature is still limited to small case series and case reports, therefore, its optimal treatment is somewhat controversial. In the current report, we introduce a case of OMMMT which was successfully treated with Platinum-based combination chemotherapy after optimal cytoreductive surgery. The clinical manifestations, pathologic characteristics, diagnosis and management of these tumours are reviewed here. Although the most effective treatment is currently unknown, optimal cytoreductive surgery and platinum-based chemotherapy appears to improve the outcomes. Despite the aggressive nature of this tumour and its poor response to the treatment, management works best when cancer is found early. The stage of the disease is the most important prognostic factor. Therefore, the crucial question is how to diagnose the cancer at earlier stages rather than seeking the optimal treatment.

Immunohistochemical stains that may be useful in the differential diagnosis of metastatic colorectal tumors to the ovary and primary ovarian tumors are detailed. PMID:21160859

There are no documented cases of endometrial adenocarcinoma recurring as metaplastic carcinoma. We report of a case of endometrial adenocarcinoma, endometrioid type, recurring as metaplastic carcinoma showing sarcomatous differentiation. The tumor evolution in this case supports the prevailing opinion that Müllerian carcinosarcomas are derived from carcinomas and represent tumor progression. PMID:18412798

    We performed phylogenetic analysis of high-grade serous ovarian cancers (68 samples from seven patients), identifying constituent clones and quantifying their relative abundances at multiple intraperitoneal sites. Through whole-genome and single-nucleus sequencing, we identified evolutionary features including mutation loss, convergence of the structural genome and temporal activation of mutational processes that patterned clonal progression. We then determined the precise clonal mixtures comprising each tumor sample. The majority of sites were clonally pure or composed of clones from a single phylogenetic clade. However, each patient contained at least one site composed of polyphyletic clones. Five patients exhibited monoclonal and unidirectional seeding from the ovary to intraperitoneal sites, and two patients demonstrated polyclonal spread and reseeding. Our findings indicate that at least two distinct modes of intraperitoneal spread operate in clonal dissemination and highlight the distribution of migratory potential over clonal populations comprising high-grade serous ovarian cancers.

    Purpose This trial was undertaken to 1) determine the feasibility of enrolling asymptomatic ovarian cancer patients with Ca-125 elevation to a trial with the PKCι inhibitor, auranofin, and 2) understand patients’ perceptions of Ca-125 monitoring. Methods Asymptomatic ovarian cancer patients with Ca-125 elevation received auranofin 3 mg orally twice/day and were evaluated. Patients participated in interviews about Ca-125 monitoring. Results Ten patients were enrolled in slightly over 6 months, exceeding our anticipated rate. Four manifested stable Ca-125 levels for 1 month or longer. The median progression-free survival was 2.8 months (95% confidence interval: 1.3, 3.8 months); auranofin was well tolerated. One patient had baseline and monthly Ca-125 levels of 5570, 6085, 3511, and 2230 units/mL, respectively, stopped auranofin because of radiographic progression at 3 months, and manifested an increase in Ca-125 to 7168 units/mL approximately 3 months later. Patient interviews revealed: 1) the important role of Ca-125 in cancer monitoring; 2) ardent advocacy for Ca-125 testing; and 3) evolution toward the Ca-125 assuming a life of its own. Conclusions This study showed feasibility; and patients favored Ca-125 monitoring. One patient had a decline in Ca-125, suggesting that PKCι inhibition merits further study in ovarian cancer.

    Malignant transformation of a mature cystic teratoma (MCT) is an infrequent, often asymptomatic event. We report the first example of a struma ovarii with a focus of follicular variant of papillary thyroid carcinoma (a), mucinous adenocarcinoma (b), and strumal carcinoid tumor (c)—all three arising in one mature cystic teratoma of the ovary. From our reviews, we found limited data to guide management when these malignant foci occur within an MCT. Consideration should be given to thyroidectomy followed by total-body scanning and serum studies for foci of thyroid carcinoma and adjuvant therapy with thyroidectomy and radioablation if residual disease is identified (a). Additionally, extrapolating from data for mucinous adenocarcinomas, consideration could be given to adjuvant chemotherapy after appropriate staging (b). Strumal carcinoid tumors should be treated as tumors of low malignant potential. Observation is appropriate if after complete staging, no invasive implants are noted (c). PMID:23029627

    Present available information regarding ovarian tumors in hens is incomplete in most aspects, and this lack of knowledge hampers use of hens as models for study of ovarian cancer. A study of 466 hens ranging from 2 to 7 years of age and covering a period of more than 3 years has provided much needed information relative to reproductive tract neoplasia. On the basis of this study, it is apparent that hens have a high rate of ovarian tumors, but that such tumors are uncommon in hens less than 2 years of age. Adenocarcinomas with a high degree of morphologic variability are the most common ovarian tumors in hens. Hormonal imbalance does not appear to be a factor in the development of these adenocarcinomas. Steroidogenic and morphologically distinctive granulosa cell tumors originating from follicles in atrophic ovaries represent another common ovarian tumor type. Unique to the hen are oviductal adenocarcinomas. These tumors arise from the albumin-secreting glands of the oviduct, occur with relatively high frequency, and must be differentiated from ovarian adenocarcinomas. Images PLATE 1. PLATE 2. PLATE 3.

    Although PEGylation allows a drug delivery vehicle to have prolonged blood circulation time, it faces the problem of reduced cellular uptake. Removal of the polyethylene glycol (PEG)-shell at the appropriate time through tumor-microenvironment triggers could be a feasible solution to this problem. Here, paclitaxel (PTX)-loaded mixed micelles (PTX-mM) self-assembled from stearate-modified hyaluronic acid (SHA), mPEG-b-poly(β-amino ester) (mPEG-b-PAE), and ethylene acetyl-b-poly(β-amino ester) (EA-b-PAE) were developed. In the preparation of PTX-mM, SHA micelles were coated with EA-b-PAE followed by coloading of PTX and mPEG-b-PAE. PTX-mM were capable of extracellular pH-triggered PEG-detachment and poly(β-amino ester) (PAE)-mediated endosomal escape. When the pH was changed from pH 7.4 to pH 6.8, the particle size of PTX-mM significantly decreased from 97.5 ± 4.4 to 71.5 ± 2.3 nm. It also resulted in rapid and complete release of mPEG-b-PAE from PTX-mM as monitored using quartz crystal microbalance (QCM) technology. PTX-mM capable of PEG detachment provided significant enhancement of PTX accumulation in SKOV-3 cells compared to PEG nondetachable PTX-mM. Interestingly, intracellular transport studies using confocal laser scanning microscopy (CLSM) showed that EA-b-PAE could promote the escape of micelles from endolysosomes. The half-maximal inhibitory concentration (IC50) of PTX-mM against SKOV-3 cells was 5.7 μg/mL, and PTX-mM containing 20 μg/mL of PTX induced apoptosis in 53.0% of the cell population. PTX-mM exhibited a highly prolonged elimination half-life (t1/2, 2.83 ± 0.37 h) and improved area under the curve (AUC, 7724.82 ± 1190.75 ng/mL/h) than the PTX-loaded SHA micelles (PTX-M). Furthermore, PTX-mM showed the highest tumor inhibition rate (64.9%) and the longest survival time (53 days) against the SKOV-3 ovarian cancer xenograft models among all formulations. Taken together, the results suggested that PTX-mM have potential as an efficient

    We report the case of a 19-year-old woman experiencing lower abdominal distension and pain. Laboratory tests indicated elevated serum levels of Alpha-Fetoprotein (AFP) and human Chorionic Gonadotropin (hCG). A large mass was detected in the abdomen by physical examination and by transvaginal ultrasonography. Exploratory laparotomy was performed, and a smooth-surfaced, spherical, solid tumor was found on the left ovary, measuring 11.5 x 9.9 x 6.9 cm. Histological evaluation revealed that the tumor consisted of a combination of immature teratoma, Yolk Sac Tumor, and embryonal carcinoma; this is a very rare combination in mixed germ cell tumors.

    Yolk sac tumor (YST) occurs rarely in older women, either in association with a variety of ovarian epithelial tumors or, considerably less often, without an identifiable epithelial precursor. The patients often have elevated serum levels of α-fetoprotein that roughly correlate with the amount of the YST component. In postmenopausal women with an ovarian mass and elevated serum levels of α-fetoprotein, a tumor of this type should be suspected. Endometrioid carcinoma is the most common putative precursor, and the tumor is often associated with an endometriotic cyst; however, malignant Müllerian mixed tumor and mucinous neoplasms have also been reported as precursors. We report 4 cases of YST in postmenopausal women. Of the 3 cases with an identified epithelial component, 1 was serous carcinoma, another was clear cell adenocarcinoma, and the third was an admixture of endometrioid and clear cell adenocarcinoma arising from an endometriotic cyst. Although a precursor epithelial ovarian neoplasm, typically a malignancy (somatic carcinoma), is usually identified, no precursor neoplasm was observed in 1 of our cases and in 5 cases from the literature. We believe that YSTs in older women, whether or not an epithelial component is detected histologically, constitute a single entity that is distinct from YSTs in younger patients and should be treated aggressively. Neoplasms with a YST component in older women are less responsive to the chemotherapy currently used for ovarian germ cell tumors; therefore, adjuvant therapy should include platinum-based chemotherapy designed to treat both epithelial ovarian cancer and germ cell tumors. Of the 24 reported cases, including our own, 17 died of neoplasms within 25 months and another was living with disease at 2 months. However, 2 more recent patients treated aggressively with platinum-based chemotherapy designed to treat both epithelial and germ cell tumor components with stage 1 disease are living and have been disease free >1

  11. Regulation of microRNA biosynthesis and expression in 2102Ep embryonal carcinoma stem cells is mirrored in ovarian serous adenocarcinoma patients

    PubMed Central

    2009-01-01

    Background Tumours with high proportions of differentiated cells are considered to be of a lower grade to those containing high proportions of undifferentiated cells. This property may be linked to the differentiation properties of stem cell-like populations within malignancies. We aim to identify molecular mechanism associated with the generation of tumours with differing grades from malignant stem cell populations with different differentiation potentials. In this study we assessed microRNA (miRNA) regulation in two populations of malignant Embryonal Carcinoma (EC) stem cell, which differentiate (NTera2) or remain undifferentiated (2102Ep) during tumourigenesis, and compared this to miRNA regulation in ovarian serous carcinoma (OSC) patient samples. Methods miRNA expression was assessed in NTera2 and 2102Ep cells in the undifferentiated and differentiated states and compared to that of OSC samples using miRNA qPCR. Results Our analysis reveals a substantial overlap between miRNA regulation in 2102Ep cells and OSC samples in terms of miRNA biosynthesis and expression of mature miRNAs, particularly those of the miR-17/92 family and clustering to chromosomes 14 and 19. In the undifferentiated state 2102Ep cells expressed mature miRNAs at up to 15,000 fold increased levels despite decreased expression of miRNA biosynthesis genes Drosha and Dicer. 2102Ep cells avoid differentiation, which we show is associated with consistent levels of expression of miRNA biosynthesis genes and mature miRNAs while expression of miRNAs clustering to chromosomes 14 and 19 is deemphasised. OSC patient samples displayed decreased expression of miRNA biosynthesis genes, decreased expression of mature miRNAs and prominent clustering to chromosome 14 but not 19. This indicates that miRNA biosynthesis and levels of miRNA expression, particularly from chromosome 14, are tightly regulated both in progenitor cells and in tumour samples. Conclusion miRNA biosynthesis and expression of mature mi

    The primary origin of some ovarian mucinous tumors may be challenging to determine, because some metastases of extraovarian origin may exhibit gross, microscopic, and immunohistochemical features that are shared by some primary ovarian mucinous tumors. Metastases of primary colorectal, appendiceal, gastric, pancreatic, and endocervical adenocarcinomas may simulate primary ovarian mucinous cystadenoma, mucinous borderline tumor, or mucinous adenocarcinoma. Recently, immunohistochemical expression of SATB2, a transcriptional regulator involved in osteoblastic and neuronal differentiation, has been shown to be a highly sensitive marker of normal colorectal epithelium and of colorectal adenocarcinoma. SATB2 expression has not been reported in normal epithelium of the female reproductive tract. Therefore, we hypothesized that SATB2 may be of value in distinguishing ovarian metastases of colorectal adenocarcinoma from primary ovarian mucinous tumors and from primary ovarian endometrioid tumors. Among primary ovarian tumors, SATB2 staining was observed in 0/22 mucinous cystadenomas that lacked a component of mature teratoma, 4/12 mucinous cystadenomas with mature teratoma, 1/60 mucinous borderline tumors, 0/17 mucinous adenocarcinomas, 0/3 endometrioid borderline tumors, and 0/72 endometrioid adenocarcinomas. Among ovarian metastases, SATB2 staining was observed in 24/32 (75%) colorectal adenocarcinomas; 8/10 (80%) low-grade appendiceal mucinous neoplasms; and 4/4 (100%) high-grade appendiceal adenocarcinomas. No SATB2 staining was observed in any ovarian metastasis of pancreatic, gastric, gallbladder, or endocervical origin. Evaluation of primary extraovarian tumors showed the highest incidences of SATB2 staining among primary colorectal adenocarcinomas (71%), primary appendiceal low-grade mucinous neoplasms (100%), and primary appendiceal high-grade adenocarcinomas (100%). Similar to their metastatic counterparts, none of the primary pancreatic or gastric

    Sox10 is a transcription factor regulating the development of several cell lineages and is involved in tumor development. However, the clinicopathological relevance of Sox10 expression in ovarian cancer has not been examined. We assessed expression of Sox10 in ovarian epithelial tumors by immunohistochemistry and assessed its prognostic value by analyzing the correlation between its expression and clinicopathological factors. We used tissue microarrays including 244 ovarian epithelial tumors. Sox10 staining was found in the cytoplasm or nucleus of tumor cells. Malignant serous, mucinous, and endometrioid tumors were significantly more likely to express Sox10 than benign and borderline tumors. Expression patterns in adenocarcinomas were different for histologic subtypes: nuclear Sox10 staining was common in clear-cell adenocarcinomas and serous adenocarcinomas, whereas all cases of mucinous and endometrioid tumors were negative for nuclear staining. Nuclear Sox10 staining was also associated with chemoresistance and shorter overall survival in ovarian adenocarcinomas, notably in high-grade serous adenocarcinoma. Sox10 is expressed in many ovarian carcinomas, suggesting that it might be involved in oncogenesis of ovarian carcinoma. Expression pattern of Sox10 differs between histological subtypes. Nuclear Sox10 expression is an independent indicator of poor prognosis in ovarian adenocarcinomas, notably in high-grade serous adenocarcinomas. PMID:26951260

    The 2015 WHO classification of tumors of the lung, pleura, thymus and heart has just been published with numerous important changes from the 2004 WHO classification. The most significant changes involve (1) use of immunohistochemistry throughout the classification, (2) integration of molecular testing for personalized strategies for advanced lung cancer patients, (3) a new classification for small biopsies and cytology, (4) a new classification of lung adenocarcinoma as proposed by the 2011 IASLC/ATS/ERS, (5) restriction of the diagnosis of large cell carcinoma only to resected tumors that lack any clear morphologic or immunohistochemical differentiation. Regarding adenocarcinoma, the terms bronchioloalveolar carcinoma (BAC) and mixed subtype adenocarcinoma have been suppressed and replaced for the former by the term adenocarcinoma in situ (AIS) as a preinvasive lesion to join atypical adenomatous hyperplasia (AAH). A new category has been defined, the minimally invasive adenocarcinoma (MIA), and invasive adenocarcinomas are now classified according to the predominant subtype after subtyping by semi-quantitatively percentage of various subtypes present in 5% increments. The term "lepidic" is restricted to a non-invasive component (previously classified as BAC) present as part of an invasive adenocarcinoma. "Invasive mucinous adenocarcinoma" is used for formerly adenocarcinomas classified as mucinous BAC, excluding tumors that meet criteria for AIS or MIA. The subtypes of clear cell and signet ring adenocarcinoma are discontinued, as well the term of mucinous cystadenocarcinoma, included in the category of colloid adenocarcinoma. Thus new classification of lung adenocarcinoma is sustained by genetics and has clinical impact for therapeutic strategies. PMID:26791238

    Cytogenetic studies of ovarian cancer have been conducted in the Medicine Branch, NCI, National Institutes of Health for 5 years. A total of 72 patients were studied by direct preparation and/or 1- to 3-day short-term culture of ascites (86 samples), pleural fluid (4 samples), and tumor (2 samples). Repeat examinations (1-24 months later) were performed in 7 of the 72 patients. Forty-four patients (62%) were successfully analyzed with banding techniques: 6 patients had adenocarcinoma, 7 had serous adenocarcinoma, 13 had serous papillary adenocarcinoma, 7 had serous papillary cystadenocarcinoma, 2 had mucinous adenocarcinoma, 6 had undifferentiated or poorly differentiated adenocarcinoma, 1 had clear cell adenocarcinoma, and 2 were not classified. Of these 44 patients, 29 had received prior chemotherapy, 14 were untreated, and in 1 patient the treatment status was unknown. Aneuploidy was observed in all patients and there was considerable variation in the chromosome numbers (even within single samples), often ranging from diploidy to triploidy to tetraploidy. All 44 patients had numerical abnormalities and 39 had structural abnormalities. The chromosomes most frequently involved in structural abnormalities (in decreasing order according to the number of patients involved) were #1, #3, #2, #4, #9, #10, #15, #19, #6, and #11; the least involved chromosomes were #21 and #5. Clone formation and the number of chromosomes involved in structural abnormalities increased with duration of disease and were more extensive in patients treated with chemotherapy than in patients treated with surgery alone. Our data did not show a deletion of chromosome #6 (6q-) to be specific for ovarian cancer. PMID:6690026

    A 71-year-old female patient underwent urgent laparotomy due to severe right lower quadrant abdominal pain and fever. Macroscopically duplex coecal and transverse colon cancer as well as a sigmoid or left ovarian cancer were suspected. Pathological findings revealed synchronous left ovarian and transverse colonic neoplasms. Both primaries metastatized to their regional lymph nodes. Furthermore, the ovarian cancer infiltrating the sigmoid colon gave distant metastasis in the coecum, too. Ovarian cancer histology showed papillary adenocarcinoma, and transverse colon cancer was a tubular adenocarcinoma. The affected lymph nodes were clearly distinguished by immunohistochemistry staining: ovarian metastases were CK7 positive, and colonic metastases were CK20 and CEA positive. The patient was treated with combinated chemotherapy: FOLFOX-4 two weekly and paclitaxel monotherapy every other week. The patient tolerated this combined treatment well. The authors conclude that multiple synchronous neoplasms can be treated with individualized chemotherapeutic protocol with good efficacy and few adverse reactions. PMID:26027602

    Ovarian carcinomas are a heterogeneous group of neoplasms traditionally sub-classified based on type and degree of differentiation. Although current clinical management of ovarian carcinoma largely fails to take this heterogeneity into account, it is becoming evident that each major histological type has characteristic genetic defects that deregulate specific signaling pathways in the tumor cells. Moreover, within the most common histological types, the molecular pathogenesis of low-grade versus high-grade tumors appears to be largely distinct. Mouse models of ovarian carcinoma have been developed that recapitulate many of the morphological features, biological behavior, and gene expression patterns of selected subtypes of ovarian cancer. Such models will likely prove useful for studying ovarian cancer biology and for pre-clinical testing of molecularly targeted therapeutics, which may ultimately lead to better clinical outcomes for women with ovarian cancer.

    Ovarian cancer metastasis to the spinal cord is quite rare, and few case reports have been published previously. Herein, we present a case of a patient who was treated for ovarian cancer and was thought to be disease free for 17 months, then presented with lower limb weakness. She was found to have a T11-T12 metastatic intramedullary spinal cord lesion. On pathology, the diagnosis of metastatic ovarian adenocarcinoma was made. This report highlights the importance of maintaining a low threshold for ovarian cancer metastases to the spinal cord when patients present with neurologic sequelae, even in the setting of normal laboratory values, as early detection can prevent permanent neurological consequences.

    Estrogen signaling influences the development and progression of ovarian tumors, but the underlying mechanisms are not well understood. In a previous study we demonstrated that impairment of estrogen receptor alpha (ERα)-mediated olfactomedin 4 (OLFM4) expression promotes the malignant progression of endometrioid adenocarcinoma, and we identified OLFM4 as a potential target of miR-486-5p. In this study we investigated the role of OLFM4 in ovarian serous adenocarcinoma. Ovarian serous adenocarcinoma tissues had reduced OLFM4 expression. Expression of OLFM4 was positively correlated with ERα expression, and estrogen (E2) treatment in ovarian cancer cells induced OLFM4 expression in an ERα-dependent manner. In contrast to ERα, miR-486-5p levels were inversely correlated with OLFM4 expression in ovarian serous adenocarcinoma. Ovarian cancer cells transfected with miR-486-5p mimics showed decreased OLFM4 mRNA expression, and ovarian cancer cells treated with E2 showed reduced cellular miR-486-5p levels. OLFM4 knockdown enhanced proliferation, migration, and invasion by ovarian cancer cells. Low expression of OLFM4 was also associated with high tumor FIGO stage and poor tumor differentiation. These results suggest OLFM4 is downregulated by miR-486-5p, which contributes to ovarian cancer tumorigenesis. Conversely, estrogen receptor signaling downregulates miR-486-5p and upregulates OLFM4 expression, slowing the development and progression of ovarian cancer. PMID:26871282

    Ovarian carcinoma is the most lethal gynecological malignancy among women and its poor prognosis is mainly due to metastasis. Chemokine receptor CCR9 is primarily expressed by a small subset of immune cells. The interactions between CCL25 and CCR9 have been implicated in leukocyte trafficking to the small bowel, a frequent metastatic site for ovarian cancer cells. We have previously shown that ovarian cancer cells express CCR9 and play an important role in cell migration, invasion and survival in the presence of its natural ligand in vitro. In this study, we have evaluated the expression of CCR9 and CCL25 in ovarian cancer cells and clinical samples. Ovarian cancer tissue microarrays from University of Alabama at Birmingham and AccuMax were stained for CCR9 and CCL25. Aperio ScanScope was used to acquire 80X digital images and expression analysis of CCR9 and CCL25. Flow cytometry and the Image stream system were used to conform the expression of CCR9 and CCL25 in ovarian cancer cells. Our results show significantly higher (p<0.001) expression of CCR9 and CCL25 in serous adenocarcinoma followed by serous papillary cystadenoma, endometrioid adenocarcinoma, mucinous adenocarcinoma, cystadenoma, mucinous boderline adenocarcinoma, clear cell carcinoma, granulosa cell tumor, dysgerminoma, transitional cell carcinoma, Brenner tumor, yolk sac tumor, adenocarcinoma and fibroma cases, compared to non-neoplastic ovarian tissue. Similar to tissue expression, CCR9 was also significantly expressed by the ovarian cancer cell lines (OVCAR-3 and SK-OV-3) in comparison to normal adult ovarian epithelial cell. We provide the first evidence that CCR9 and its natural ligand CCL25 are highly expressed by ovarian cancer tissue and their expression correlates with histological subtypes. Expression of this chemokine receptor and its ligand CCL25 within primary tumor tissue further suggests a potential role of this chemokine-receptor axis in ovarian cancer progression. PMID:21637913

We encountered a case of ovarian CCAC arising from benign and borderline adenofibromas of the clear cell and endometrioid types with endometriosis in a 53-year-old woman. Regions of the adenofibromas showed transformation to CCAC and regions of the endometriosis showed atypical endometriotic cysts. This case demonstrates that CCAC can arise from CCAF or endometriosis.

    2016-01-01

    Introduction Synchronous gynecologic primary cancers are uncommon. When present, the most frequent malignancies consist of endometrial and ovarian carcinomas. Here we report an exceedingly rare case of concurrent uterine adenocarcinoma and leiomyosarcoma. Case presentation A 60 year-old female presented with four years of postmenopausal bleeding. An endometrial sampling showed grade 2 endometrioid adenocarcinoma. She proceeded with hysterectomy that contained an anterior endometrial mass and a posterior myometrial mass. The final pathology demonstrated concurrent uterine adenocarcinoma and leiomyosarcoma. Discussion To the best of our knowledge, this is the third reported case of simultaneous uterine adenocarcinoma and leiomyosarcoma. As this presentation is infrequent with limited literature, this caused a clinical management conundrum. Unfortunately, the follow-up PET scan suggested possible recurrence or metastasis three months after the surgery. Conclusion Simultaneous uterine adenocarcinoma and leiomyosarcoma is an exceptionally rare event. As the experience is limited, a multidisciplinary approach in managing these patients may be the best option currently available. PMID:27022754

    Pancreatic cancer is one of the deadliest cancers with a very poor prognosis. Recently, there has been a significant increase in research directed towards identifying potential biomarkers that can be used to diagnose and provide prognostic information for pancreatic cancer. These markers can be used clinically to optimize and personalize therapy for individual patients. In this review, we focused on 3 biomarkers involved in the DNA damage response pathway and the necroptosis pathway: Chromodomain-helicase-DNA binding protein 5, chromodomain-helicase-DNA binding protein 7, and mixed lineage kinase domain-like protein. The aim of this article is to review present literature provided for these biomarkers and current studies in which their effectiveness as prognostic biomarkers are analyzed in order to determine their future use as biomarkers in clinical medicine. Based on the data presented, these biomarkers warrant further investigation, and should be validated in future studies. PMID:27096031

    The objective of this teaching case is to report the excellent results of using lattice radiation therapy (LTR) for the treatment of a large metastasis from ovarian carcinosarcoma. This new technical concept extrapolates the traditional spatially fractionated radiation therapy (GRID) technique to advanced three-dimensional (3D) high-dose radiation therapy using modern instrumentation in radiation oncology. We report a case of a 61-year-old female with a large metastatic mass from ovarian carcinosarcoma treated by this procedure with excellent clinical and image-based follow-up results for more than four years.

    From December 2000 until 2010, the researchers at Royan Institute conducted a wide range of investigations on ovarian tissue cryopreservation with the intent to provide fertility pres- ervation to cancer patients that were considered to be candidates for these services. In 2010, Royan Institute established the Royan Human Ovarian Tissue Bank as a subgroup of the Embryology Department. Since its inception, approximately 180 patients between the ages of 747 years have undergone consultations. Ovarian samples were cryopreserved from 47 patients (age: 7-35 years) diagnosed with cervical adenocarcinoma (n=9); breast carcinoma (n=7), Ewing’s sarcoma (n=7), opposite side ovarian tumor (n=7), endometrial adenocarci- noma (n=4), malignant colon tumors (n=3), as well as Hodgkin’s lymphoma, major thalas- semia and acute lymphoblastic leukemia (n=1-2 patients for each disease). Additionally, two patients requested ovarian tissue transplantation after completion of their treatments.

    Ovarian cancer is not a single disease and can be subdivided into at least five different histological subtypes that have different identifiable risk factors, cells of origin, molecular compositions, clinical features and treatments. Ovarian cancer is a global problem, is typically diagnosed at a late stage and has no effective screening strategy. Standard treatments for newly diagnosed cancer consist of cytoreductive surgery and platinum-based chemotherapy. In recurrent cancer, chemotherapy, anti-angiogenic agents and poly(ADP-ribose) polymerase inhibitors are used, and immunological therapies are currently being tested. High-grade serous carcinoma (HGSC) is the most commonly diagnosed form of ovarian cancer and at diagnosis is typically very responsive to platinum-based chemotherapy. However, in addition to the other histologies, HGSCs frequently relapse and become increasingly resistant to chemotherapy. Consequently, understanding the mechanisms underlying platinum resistance and finding ways to overcome them are active areas of study in ovarian cancer. Substantial progress has been made in identifying genes that are associated with a high risk of ovarian cancer (such as BRCA1 and BRCA2), as well as a precursor lesion of HGSC called serous tubal intraepithelial carcinoma, which holds promise for identifying individuals at high risk of developing the disease and for developing prevention strategies.

    Backgrounds. Magnifying endoscopy with narrow-band imaging (NBI-ME) is useful for diagnosing differentiated early gastric cancer (D-EGC). D-EGC is classified as high- or low-grade based on its glandular architectural and cytological atypia. Low-grade, well-differentiated tubular adenocarcinoma (LG-tub1) mixed with high-grade tub1 (HG-tub1) and/or other histological types (M-LG-tub1) may indicate a primitive high-risk malignant lesion compared to histologically simple-type LG-tub1 (S-LG-tub1). Because LG-tub1 is occasionally difficult to diagnose due to its unclear demarcation under conventional white light endoscopy, early precise diagnoses are important. Methods. We compared NBI-ME and postendoscopic submucosal dissection histological findings for 30 S-LG-tub1 and 15 M-LG-tub1 lesions. We classified the NBI-ME findings of S-LG-tub1 (and not D-EGC) into four patterns. The differential diagnosis between M-LG-tub1 and S-LG-tub1 depended on the presence of more than one of these patterns without or with other patterns (referred to as “limited-to-four-pattern [LFP] sign-positive” and “sign-negative”, resp.). Result. The sensitivity, specificity, accuracy, positive and negative predictive values, and intraobserver and interobserver agreement, using the “LFP sign” for the differential diagnosis between M-LG-tub1 and S-LG-tub1, were 87.9%, 91.7%, 88.9%, 96.7%, 73.3%, and k = 0.842 and k = 0.737, respectively. Conclusion. NBI-ME may be useful in differentiating between high-risk M-LG-tub1 and low-risk S-LG-tub1. PMID:27127502

    We have earlier demonstrated that breast cancer and small-cell lung cancer express functional NMDA receptors that can be targeted to promote cancer cell death. Human ovarian cancer tissues and human ovarian cancer cell lines (SKOV3, A2008, and A2780) have now been shown to also express NMDA-receptor subunit 1 (GluN1) and subunit 2B (GluN2B). Seventeen ovarian cancers in two arrays were screened by immunohistochemistry using polyclonal antibodies that recognize an extracellular moiety on GluN1 and on GluN2B. These specimens comprised malignant tissue with pathology diagnoses of serous papillary cystadenocarcinoma, endometrioid adenocarcinoma, and clear-cell carcinoma. Additionally, archival tissues defined as ovarian adenocarcinoma from ten patients treated at this institute were also evaluated. All of the cancerous tissues demonstrated positive staining patterns with the NMDA-receptor antibodies, while no staining was found for tumor-adjacent normal tissues or sections of normal ovarian tissue. Human ovarian adenocarcinoma cell lines (A2008, A2780, SKOV3) were demonstrated to express GluN1 by Western blotting, but displayed different levels of expression. Through immunocytochemistry utilizing GluN1 antibodies and imaging using a confocal microscope, we were able to demonstrate that GluN1 protein is expressed on the surface of these cells. In addition to these findings, GluN2B protein was demonstrated to be expressed using polyclonal antibodies against this protein. Treatment of all ovarian cell lines with antibodies against GluN1 was found to result in decreased cell viability (P<0.001), with decreases to 10%-25% that of untreated cells. Treatment of control HEK293 cells with various dilutions of GluN1 antibodies had no effect on cell viability.

    Serum amyloid A (SAA) is an acute phase protein which is expressed primarily in the liver as a part of the systemic response to various injuries and inflammatory stimuli; its expression in ovarian tumors has not been described. Here, we investigated the expression of SAA in human benign and malignant ovarian epithelial tumors. Non-radioactive in situ hybridization applied on ovarian paraffin tissue sections revealed mostly negative SAA mRNA expression in normal surface epithelium. Expression was increased gradually as epithelial cells progressed through benign and borderline adenomas to primary and metastatic adenocarcinomas. Similar expression pattern of the SAA protein was observed by immunohistochemical staining. RT-PCR analysis confirmed the overexpression of the SAA1 and SAA4 genes in ovarian carcinomas compared with normal ovarian tissues. In addition, strong expression of SAA mRNA and protein was found in the ovarian carcinoma cell line OVCAR-3. Finally, patients with ovarian carcinoma had high SAA serum levels, which strongly correlated with high levels of CA-125 and C-reactive protein. Enhanced expression of SAA in ovarian carcinomas may play a role in ovarian tumorigenesis and may have therapeutic application. PMID:20713982

    Human epididymis protein 4 (HE4) is a recognized biomarker in ovarian and endometrial cancer and over-expressed in pancreatic adenocarcinoma. The diagnostic value of HE4 in pancreatic adenocarcinoma remains unknown. Here we elucidate mRNA, protein and serum level of HE4 in pancreatic adenocarcinoma. HE4 mRNA level in tumor adjacent tissues and pancreatic adenocarcinoma tissues were tested by real time-PCR. Tissue microarray containing normal, adenocarcinoma, and adjacent pancreatic tissue was tested by immunohistochemistry (IHC). Serum level of HE4, carbohydrate antigen 19-9 (CA19-9), carbohydrate antigen 15-3 (CA15-3) and carbohydrate antigen 125 (CA125) were detected by ELISA assay in control and tumor patients. Further we compared the sensitivity and specificity of determining HE4, CA19-9, CA15-3, and CA125 for diagnosis of pancreatic adenocarcinoma and assessed the complementary diagnostic value of HE4, CA19-9, CA15-3 and CA125. Real time PCR showed significantly increased HE4 mRNA level in pancreatic adenocarcinoma compared with control. Result of IHC showed that HE4 significantly higher expressed in the human pancreatic carcinoma tissues than in both normal and adjacent non-tumorous pancreatic tissues, and the staining intensity is inversely correlated with the clinical stage. HE4 was highly expressed in early stage of pancreatic adenocarcinoma. Serum HE4 level is higher in cases with pancreatic adenocarcinoma than in the controls. Serum HE4 levels could research to a sensitivity of 45.83% and specificity of 93.75% when the Cutoff was set at 4.59 ng/mL. The Combined HE4 and CA19-9 increased the sensitivity to 83.33%; and interestingly, the combination of HE4 with CA15-3 led to the most powerful sensitivity of 87.5%. Combined with CA19-9 and CA15-3, HE4 could be a potential biomarker to improve the diagnostic power for pancreatic adenocarcinoma. PMID:25642754

    A catalogue of molecular aberrations that cause ovarian cancer is critical for developing and deploying therapies that will improve patients' lives. The Cancer Genome Atlas project has analysed messenger RNA expression, microRNA expression, promoter methylation and DNA copy number in 489 high-grade serous ovarian adenocarcinomas and the DNA sequences of exons from coding genes in 316 of these tumours. Here we report that high-grade serous ovarian cancer is characterized by TP53 mutations in almost all tumours (96%); low prevalence but statistically recurrent somatic mutations in nine further genes including NF1, BRCA1, BRCA2, RB1 and CDK12; 113 significant focal DNA copy number aberrations; and promoter methylation events involving 168 genes. Analyses delineated four ovarian cancer transcriptional subtypes, three microRNA subtypes, four promoter methylation subtypes and a transcriptional signature associated with survival duration, and shed new light on the impact that tumours with BRCA1/2 (BRCA1 or BRCA2) and CCNE1 aberrations have on survival. Pathway analyses suggested that homologous recombination is defective in about half of the tumours analysed, and that NOTCH and FOXM1 signalling are involved in serous ovarian cancer pathophysiology.

    Optical imaging methods have the potential to detect ovarian cancer at an early, curable stage. Optical imaging has the disadvantage that high resolution techniques require access to the tissue of interest, but miniature endoscopes that traverse the natural orifice of the reproductive tract, or access the ovaries and fallopian tubes through a small incision in the vagina wall, can provide a minimally-invasive solution. We have imaged both rodent and human ovaries and fallopian tubes with a variety of endoscope-compatible modalities. The recent development of fiber-coupled femtosecond lasers will enable endoscopic multiphoton microscopy (MPM). We demonstrated two- and three-photon excited fluorescence (2PEF, 3PEF), and second- and third-harmonic generation microscopy (SHG, THG) in human ovarian and fallopian tube tissue. A study was undertaken to understand the mechanisms of contrast in these images. Six patients (normal, cystadenoma, and ovarian adenocarcinoma) provided ovarian and fallopian tube biopsies. The tissue was imaged with three-dimensional optical coherence tomography, multiphoton microscopy, and frozen for histological sectioning. Tissue sections were stained with hematoxylin and eosin, Masson's trichrome, and Sudan black. Approximately 1 μm resolution images were obtained with an excitation source at 1550 nm. 2PEF signal was absent. SHG signal was mainly from collagen. 3PEF and THG signal came from a variety of sources, including a strong signal from fatty connective tissue and red blood cells. Adenocarcinoma was characterized by loss of SHG signal, whereas cystic abnormalities showed strong SHG. There was limited overlap of two- and three- photon signals, suggesting that three-photon imaging can provide additional information for early diagnosis of ovarian cancer.

    We report a case of massive intra-abdominal undifferentiated carcinoma derived from a tiny well-differentiated endometrioid adenocarcinoma of the ovary. The patient, a 56-year-old woman, who presented with a large intra-abdominal mass, underwent cytoreductive surgery with hysterectomy and bilateral salpingo-oophorectomy. Macroscopically, the intra-abdominal mass was composed of fragile and solid tumor components with extensive necro-hemorrhagic areas, mimicking a primary peritoneal tumor. Both ovaries were apparently normal in size, but a cut section of the right ovary revealed a 2-cm solid and cystic tumor showing focal rupture to the peritoneal surface. The intra-abdominal tumor consisted of pleomorphic cells without specific differentiation, showing diffuse sheet-like proliferation. The right ovarian tumor was a histologically well-differentiated endometrioid adenocarcinoma. Both the intra-abdominal undifferentiated tumor and the ovarian adenocarcinoma cells were immunohistochemically positive for keratin AE1/3, Ber-EP4, and CD10. Epithelial membrane antigen was positive only in the ovarian adenocarcinoma component, and vimentin was diffusely positive only in the intra-abdominal undifferentiated tumor component. Calretinin was negative in both tumor components. Allelotype analysis using 24 polymorphic markers located on 12 chromosomal arms showed that the intra-abdominal undifferentiated carcinoma and ovarian adenocarcinoma components had a high concordance rate (88%) of allelic patterns including identical allelic loss patterns at 7 chromosomal loci, suggesting a common genetic lineage. These data suggest that ovarian endometrioid adenocarcinoma, even when small in size, can give rise to a massive undifferentiated carcinoma filling the peritoneal cavity. PMID:20567143

    Epithelial ovarian cancer is diagnosed less than 25% of the time when the cancer is confined to the ovary, leading to 5-year survival rates of less than 30%. Therefore, there is an urgent need for early diagnostics for ovarian cancer. Our study using glycotranscriptome comparative analysis of endometrioid ovarian cancer tissue and normal ovarian tissue led to the identification of distinct differences in the transcripts of a restricted set of glycosyltransferases involved in N-linked glycosylation. Utilizing lectins that bind to glycan structures predicted to show changes, we observed differences in lectin-bound glycoproteins consistent with some of the transcript differences. In this study, we have extended our observations by the use of selected lectins to perform a targeted glycoproteomic analysis of ovarian cancer and normal ovarian tissues. Our results have identified several glycoproteins that display tumor-specific glycosylation changes. We have verified these glycosylation changes on glycoproteins from tissue using immunoprecipitation followed by lectin blot detection. The glycoproteins that were verified were then analyzed further using existing microarray data obtained from benign ovarian adenomas, borderline ovarian adenocarcinomas, and malignant ovarian adenocarcinomas. The verified glycoproteins found to be expressed above control levels in the microarray data sets were then screened for tumor-specific glycan modifications in serum from ovarian cancer patients. Results obtained from two of these glycoprotein markers, periostin and thrombospondin, have confirmed that tumor-specific glycan changes can be used to distinguish ovarian cancer patient serum from normal serum.

    Pancreatic adenocarcinoma remains the fourth leading cause of cancer-related death and is one of the most aggressive malignant tumors with an overall 5-year survival rate of less than 4%. Surgical resection remains the only potentially curative treatment but is only possible for 15%-20% of patients with pancreatic adenocarcinoma. About 40% of patients have locally advanced nonresectable disease. In the past, determination of pancreatic cancer resectability was made at surgical exploration. The development of modern imaging techniques has allowed preoperative staging of patients. Institutions disagree about the criteria used to classify patients. Vascular invasion in pancreatic cancers plays a very important role in determining treatment and prognosis. There is no evidence-based consensus on the optimal preoperative imaging assessment of patients with suspected pancreatic cancer and a unified definition of borderline resectable pancreatic cancer is also lacking. Thus, there is much room for improvement in all aspects of treatment for pancreatic cancer. Multi-detector computed tomography has been widely accepted as the imaging technique of choice for diagnosing and staging pancreatic cancer. With improved surgical techniques and advanced perioperative management, vascular resection and reconstruction are performed more frequently; patients thought once to be unresectable are undergoing radical surgery. However, when attempting heroic surgery, a realistic approach concerning the patient’s age and health status, probability of recovery after surgery, perioperative morbidity and mortality and life quality after tumor resection is necessary.

    Aims A subset of colorectal carcinomas (CRCs) architecturally and cytologically resembles adenomatous change, making them difficult to diagnose on biopsy. This subset has not been well-characterized to date. Methods and results For 35 carcinomas with adenomatous-like areas (cytologic and surface architectural appearance that would be insufficient to warrant a diagnosis of adenocarcinoma if evaluated on biopsy), we recorded staging information, molecular data, clinical outcome, whether precursor adenoma was present, and whether prior biopsy had been diagnosed as malignant. Despite advanced T-category in 23 (66%) tumors, only 7 (20%) had nodal metastases, and only 5 patients (15%) developed distant metastases. Fifteen cases (43%) had been diagnosed as adenoma on biopsy. Twenty-one resections (60%) showed no residual associated adenoma, including 9 called adenoma on biopsy. Median follow-up was 44 months. Four patients (12%) died of disease; 22 were alive at last follow-up. KRAS mutation was seen in 14/24 (58%), and 4/17 (24%) were microsatellite-unstable. Patients had significantly improved survival compared to a cohort of patients with conventional well-differentiated CRC after controlling for age and stage (p=0.011). Conclusions Adenoma-like adenocarcinoma is an uncommon variant of CRC with a low rate of metastasis and good prognosis. Biopsy diagnosis of this lesion may be challenging. PMID:25913616

    Combined ovarian tumors are found in common pathologic practice due to amazing potential of ovarian tissue to copy almost every tissue of human body and imitate many neoplasms of various other organs in a very flexible way. A multicystic tumor is presented in this case report of 35-year-old woman. It consisted of a cyst with sebum and hair and cavities with papillomatous projections and mucus. The ovarian tumor was diagnosed a mature cystic teratoma presenting mainly as dermoid cyst and mucinous adenocarcinoma in situ, arising within atypical proliferative mucinous tumor. This report demonstrates how histoformative properties are reflected in ovarian tumorigenesis. Such a stunning histoformativity makes ovaries the possible site of primary origin for malignant tumors that mimic extra ovarian differentiation. In the authors' point of view, the diagnosis of primary ovarian mucinous tumor within cystic teratoma is firm, whenever simultaneous extraovarian involvement by mucinous neoplasm is excluded.

    Physiological reproductive aging occurs as a result of a decrease in the number and quality of oocytes in ovarian cortex follicles. Although the reason for the decrease in the quality of the pool and follicular oocytes is not fully understood, endocrine, paracrine, genetic, and metabolic factors are thought to be effective. Nowadays, in order to understand the mechanisms of ovarian aging, genomic research has gained importance. The effect of co-factors, such as telomerase and ceramide, in the ovarian aging process is only getting ascertained with new research studies. The most important tests in the assessment of ovarian aging are antral follicle count and anti-Mullerian hormone. PMID:25317048

    A long-term follow-up study of 92 patients with ovarian endometriosis treated with microsurgical techniques showed that although endometriosis may persist in many patients, only seven patients required repeat ovarian surgery. Microsurgical techniques are to be recommended for the treatment of ovarian endometriosis and the prevention of postoperative adhesive disease of the ovaries. PMID:3372697

    Despite the prevalence and significant morbidity resulting from estrogen receptor positive (ER(+)) breast adenocarcinomas, there are only a few models of this cancer subtype available for drug development and arguably none for studying etiology. Those models that do exist have questionable clinical relevance. Given our goal of developing luminal models, we focused on six cell lines derived by minimal mutagenesis from normal human breast cells, and asked if any could generate clinically relevant xenografts, which we then extensively characterized. Xenografts of one cell line, 184AA3, consistently formed ER(+) adenocarcinomas that had a high proliferative rate and other features consistent with "luminal B" intrinsic subtype. Squamous and spindle cell/mesenchymal differentiation was absent, in stark contrast to other cell lines that we examined or others have reported. We explored intratumoral heterogeneity produced by 184AA3 by immunophenotyping xenograft tumors and cultured cells, and characterized marker expression by immunofluorescence and flow cytometry. A CD44(High) subpopulation was discovered, yet their tumor forming ability was far less than CD44(Low) cells. Single cell cloning revealed the phenotypic plasticity of 184AA3, consistent with the intratumoral heterogeneity observed in xenografts. Characterization of ER expression in cultures revealed ER protein and signaling is intact, yet when estrogen was depleted in culture, and in vivo, it did not impact cell or tumor growth, analogous to therapeutically resistant ER(+) cancers. This model is appropriate for studies of the etiology of ovarian hormone independent adenocarcinomas, for identification of therapeutic targets, predictive testing, and drug development.

    Ovarian metastasis of colorectal cancer is relatively rare. The present study reports two cases of synchronous ovarian metastasis from colorectal cancer, which were managed by cytoreductive surgery. In case one, a 60-year-old female patient presented with a multilocular pelvic tumor and ascites. Virtual colonoscopy revealed a mass in the sigmoid colon; however, no tumor cells were identified on histological examination. Ovarian metastasis from sigmoid colon cancer was suspected and adnexectomy was subsequently performed. Histological examination of the excised tumor revealed adenocarcinoma. Immunohistochemical analysis of the resected tumor revealed positive staining for cytokeratin (CK)20 and caudal-type homeobox 2 (CDX2), and negative staining for CK7, estrogen receptor, progesterone receptor and inhibin. The immunohistological results supported the diagnosis of ovarian metastasis from sigmoid colon cancer. In case two, a 56-year-old female patient presented with a multilocular pelvic tumor and ascites. Colonoscopy identified a rectal tumor, and histological examination revealed moderately-differentiated adenocarcinoma, which was confirmed by cytological analysis of ascites. Subsequently, ovarian metastasis from rectal cancer with peritoneal dissemination was diagnosed, and left ovariectomy and transverse colostomy were performed. Histological examination of the excised tumor revealed moderately-differentiated adenocarcinoma, and immunohistochemical investigation revealed positive staining for CK20 and CDX2, but negative staining for CK7. These immunohistological results indicated ovarian metastasis from rectal cancer. Both patients recovered well and are currently undergoing regular follow-up examinations. The observations from the two cases indicate that ovarian metastases of primary colorectal cancer may present as pelvic tumors and, thus, preoperative examination of the gastrointestinal tract is required. Furthermore, even in cases of widespread colorectal

    A 35-year-old woman underwent laparoscopic radical hysterectomy, pelvic lymphadenectomy and ovarian transposition for stage IB2 cervical adenocarcinoma. She received adjuvant concurrent chemoradiation for poor pathologic risk factors but had tumor recurrence 20 months after the surgery. Transposed ovaries were uninvolved in the recurrence and progression. Salvage chemotherapy and radiotherapy were given. Despite systemic chemotherapy and repeat pelvic radiotherapy, the patient was able to maintain ovarian function. Ovarian transposition in cervical cancer is an easily performed procedure that does not alter the prognosis of the disease in some cases. Present recommendations for its use should be reevaluated so that more premenopausal cancer patients may benefit from this underutilized procedure. PMID:23653838

    Gastric and esophageal adenocarcinomas are one of the main causes of cancer-related death worldwide. While the incidence of gastric adenocarcinoma is decreasing, the incidence of gastroesophageal junction adenocarcinoma is rising rapidly in Western countries. Considering that surgical resection is currently the major curative treatment, and that the 5-year survival rate highly depends on the pTNM stage at diagnosis, gastroesophageal adenocarcinoma management is very challenging for oncologists. Several treatment strategies are being evaluated, and among them systemic chemotherapy, to decrease recurrences and improve overall survival. The MAGIC and FNCLCC-FFCD trials showed a survival benefit of perioperative chemotherapy in patients with operable gastric and lower esophageal cancer, and these results had an impact on the European clinical practice. New strategies, including induction chemotherapy followed by preoperative chemoradiotherapy, targeted therapies in combination with perioperative chemotherapy and the new cytotoxic regimens, are currently assessed to improve current standards and help developing patient-tailored therapeutic interventions.

    Pancreatic ductal adenocarcinoma (PDAC) stands as the poorest prognostic tumor of the digestive tract, with a 5-year survival rate of less than 5%. Therapeutic options for unresectable PDAC are extremely limited and there is a pressing need for expanded therapeutic approaches to improve current options available with gemcitabine-based regimens. With PDAC displaying one of the most prominent desmoplastic stromal reactions of all carcinomas, recent research has focused on the microenvironment surrounding PDAC cells. Secreted protein acid and rich in cysteine (SPARC), which is overexpressed in PDAC, may display tumor suppressor functions in several cancers (e.g., in colorectal, ovarian, prostate cancers, and acute myelogenous leukemia) but also appears to be overexpressed in other tumor types (e.g., breast cancer, melanoma, and glioblastoma). The apparent contradictory functions of SPARC may yield inhibition of angiogenesis via inhibition of vascular endothelial growth factor, while promoting epithelial-to-mesenchymal transition and invasion through matrix metalloprotease expression. This feature is of particular interest in PDAC where SPARC overexpression in the stroma stands along with inhibition of angiogenesis and promotion of cancer cell invasion and metastasis. Several therapeutic strategies to deplete stromal tissue have been developed. In this review, we focused on key preclinical and clinical data describing the role of SPARC in PDAC biology, the properties, and mechanisms of delivery of drugs that interact with SPARC and discuss the proof-of-concept clinical trials using nab-paclitaxel.

    Sixteen women with adenocarcinoma of the cervical stump were treated over a 15-year period. The median survivals of 40 months for stage IB and 17 months for stages II and III were significantly worse compared with those for patients treated for cervical adenocarcinoma of the intact uterus or squamous carcinoma of the cervical stump. The poor results were due to both local and distant failure. Implications regarding tumor radiosensitivity and adjuvant therapy in these high-risk patients are discussed.

    2011-01-01

    Summary The Cancer Genome Atlas (TCGA) project has analyzed mRNA expression, miRNA expression, promoter methylation, and DNA copy number in 489 high-grade serous ovarian adenocarcinomas (HGS-OvCa) and the DNA sequences of exons from coding genes in 316 of these tumors. These results show that HGS-OvCa is characterized by TP53 mutations in almost all tumors (96%); low prevalence but statistically recurrent somatic mutations in 9 additional genes including NF1, BRCA1, BRCA2, RB1, and CDK12; 113 significant focal DNA copy number aberrations; and promoter methylation events involving 168 genes. Analyses delineated four ovarian cancer transcriptional subtypes, three miRNA subtypes, four promoter methylation subtypes, a transcriptional signature associated with survival duration and shed new light on the impact on survival of tumors with BRCA1/2 and CCNE1 aberrations. Pathway analyses suggested that homologous recombination is defective in about half of tumors, and that Notch and FOXM1 signaling are involved in serous ovarian cancer pathophysiology. PMID:21720365

    An exploratory laparotomy on a mixed-breed bitch of an estimated age of 5 years revealed that she had undergone ovariectomy in the past, but a cystic structure was present in the area of the right ovary and a whitish mass, approximately 3 cm in diameter, in the area of the left ovary. These structures were removed together with an apparently normal uterus. Histological examination of the cyst showed a thin layer of connective tissue, while the left ovarian mass revealed ovarian tissue and highly differentiated nervous tissue, confirmed through immunohistochemistry. A presumptive diagnosis of mature ovarian teratoma was made. Although teratomas generally contain recognizable elements from more than one of the three germ cell layers, they can also be monophasic, when there is only one germ layer component. Ovarian teratomas are rare in the dog and never before have been reported in an ovarian fragment. PMID:23279574

    The recognition of bronchioloalveolar carcinoma (BAC) as distinct from adenocarcinoma of the lung, is controversial. Using strict pathologic criteria, 43 consecutive patients with BAC were matched by year of diagnosis and compared with a similar number of patients with adenocarcinoma, and for contrast, with those with squamous and oat cell carcinoma of the lung. We demonstrated that BAC is not sex related, and is not as smoking related as the other neoplasms. Unlike epidermoid carcinoma, BAC does not show a predilection for those occupations requiring manual labor. Also, BAC is frequently distinguishable radiologically from the other three by being smaller and peripheral. A pleural tag and an air bronchogram in a mass are rather specific, and BAC is less likely to have large airway involvement and adenopathy. The percentage of patients who were free of tumor after 2 yr was greater in the BAC group than in the others, but the overall survival rate between the BAC group and the adenocarcinoma group was not. Based on inter-observer variability, there is some overlap pathologically between these 2 groups. However, when the overlap between the adenocarcinoma and the BAC groups is compared with that between the adenocarcinoma and the squamous cell carcinoma groups, the difference is not significant. We conclude that BAC should be considered a distinct clinical entity. PMID:6278997

    Most upper esophageal malignancies are squamous cell carcinomas, rarely adenocarcinomas arising from Barrett's esophagus and very rarely adenocarcinomas from heterotopic gastric mucosa without evidence of Barrett's especially in the cervical part of the esophagus. We report a case of adenocarcinoma of the polypoid type in the upper esophagus (cervical esophagus) arising from ectopic gastric mucosa, in a 60 year-old man who presented with progressive dysphagia. Accurate diagnosis by esophagogram revealed a large mass in the cervical esophagus; CAT scan showed intraluminal mass at the level of thoracic inlet, esophagogastroscopy showed a fleshy polyp (3.2cm x 3.0cm) at 20 cm from the incisors with a biopsy confirming moderately differentiated adenocarcinoma with no evidence of Barrett's esophagus. Through a left cervical approach and resection of medial third of clavicle, the tumor was removed by partial esophagectomy followed by lymph node dissection, and proved to be T1NOMO, stage I (AJCC staging 6th ed.). Post operatively, the patient received chemoradiation with no evidence of recurrence or metastasis in six years of follow up. It seems this tumor has a much better prognosis than adenocarcinomas arising from Barrett's. To our knowledge only 19 cases have been reported in literature so far. PMID:16110768

    Combined ovarian germ cell and neuroendocrine tumors are rare. Only few cases of hyperinsulinism due to ovarian ectopic secretion have been hypothesized in the literature. An ovarian tumor was diagnosed in a 76-year-old woman, referred to our department for recurrent hypoglycemia with hyperinsulinism. In vivo tests, in particular fasting test, rapid calcium infusion test, and Octreotide test were performed. Ectopic hyperinsulinemic hypoglycemia was demonstrated in vivo and hypoglycemia disappeared after hysteroadnexectomy. Histological exam revealed an ovarian germ cell tumor with neuroendocrine and Yolk sac differentiation, while immunostaining showed insulin positivity in neuroendocrine cells. A cell culture was obtained by tumoral cells, testing Everolimus, and Pasireotide. Insulin was detected in cell culture medium and Everolimus and Pasireotide demonstrated their potentiality in reducing insulin secretion, more than controlling cell viability. Nine cases of hyperinsulinism due to ovarian ectopic secretion reported in literature have been reviewed. These data confirm the ovarian tissue potentiality to induce hyperinsulinemic hypoglycemic syndrome after neoplastic transformation. PMID:25896552

    Claudins are a family of proteins and the most important component of the tight junction. They constitute a paracellular barrier that controls the flow of molecules in the intercellular space of an epithelium. Although it seems that claudin should be down regulated in cancer cell, some claudins are, in fact highly elevated in various human cancers, including ovarian cancer. Whereas the functional significance of claudin overexpression in ovarian carcinoma is unclear, these proteins are important for migration, invasion, and survival of ovarian cancer cells. They clearly represent a general pathway in tumorigenesis, are a novel marker for ovarian cancer and may become a target for therapy or diagnosis of this disease. PMID:24591894

    Ovarian mucinous tumors (OMTs) of the intestinal type share morphologic features with primary tumors of other sites, and it can often be difficult to distinguish primary ovarian from metastatic mucinous tumors. MUC1, MUC2, MUC5AC, and MUC6 expressions were studied by immunohistochemistry in 36 OMTs of intestinal type (17 malignant, 19 borderline), 18 pancreatic, 12 biliary, 15 esophageal, 9 gastric, and 7 colorectal/appendiceal adenocarcinomas. All samples were from primary sites, except for colorectal tumors which were from ovarian metastases. Borderline and malignant OMTs show similar mucin immunoprofile, being strongly and uniformly positive for MUC5AC (97.2% of cases), whereas only focally positive for MUC1 (19.4%), MUC2 (38.9%), and MUC6 (22.2%). The positive frequencies of pancreatic adenocarcinomas for MUC1, MUC2, MUC5AC, and MUC6, respectively, were 100%, 16.7%, 94.4%, and 61.1%; for biliary (cholangiocarcinomas) were 91.7%, 0%, 16.7%, and 8.3%; for esophageal carcinomas were 73.3%, 33.3%, 53.3%, and 26.7%; for gastric carcinomas were 44.4%, 44.4%, 44.4%, and 0% and for lower gastrointestinal tract cancers were 28.6%, 85.7%, 42.9%, and 0%. Our study shows that OMTs are usually MUC5AC+/MUC1-, which is different from pancreatic, biliary, esophageal, gastric, and colorectal/appendiceal carcinomas. We recommend that these mucin stains be added to the panel of immunostains to differentiate metastatic tumors to the ovary from primary OMTs. PMID:24487472

    Despite the poor prognosis of ovarian cancer and the importance of early diagnosis, there are no reliable noninvasive biomarkers for detection in the early stages of disease. Therefore, to identify novel ovarian cancer markers with potential utility in early-stage screening protocols, we have undertaken an unbiased and comprehensive analysis of gene expression in primary ovarian tumors and normal human ovarian surface epithelium (HOSE) using Serial Analysis of Gene Expression (SAGE). Specifically, we have generated SAGE libraries from three serous adenocarcinomas of the ovary and, using novel statistical tools, have compared these to SAGE data derived from two pools of normal HOSE. Significantly, in contrast to previous SAGE-based studies, our normal SAGE libraries are not derived from cultured cell lines. We have also compared our data with publicly available SAGE data obtained from primary tumors and "normal" HOSE-derived cell lines. We have thus identified several known and novel genes whose expressions are elevated in ovarian cancer. These include but are not limited to CLDN3, WFDC2, FOLR1, COL18A1, CCND1, and FLJ12988. Furthermore, we found marked differences in gene expression patterns in primary HOSE tissue compared with cultured HOSE. The use of HOSE tissue as a control for these experiments, along with hierarchical clustering analysis, identified several potentially novel biomarkers of ovarian cancer, including TACC3, CD9, GNAI2, AHCY, CCT3, and HMGA1. In summary, these data identify several genes whose elevated expressions have not been observed previously in ovarian cancer, confirm the validity of several existing markers, and provide a foundation for future studies in the understanding and management of this disease.

    Introduction Ovarian cancer is the second most common malignancy in women, the most common cause of gynecologic cancer deaths, and most patients have advanced stage disease at the time of diagnosis. The purpose of this study was to estimate the 5-year survival of patients with epithelial ovarian cancer based on age, tumor histology, stage of disease, and type of treatment. Methods This study was conducted on 120 patients with epithelial ovarian cancer referred to Shahid Sadoughi hospital and Shah Vali oncology clinic of Yazd from 2006 to 2012. Demographic data and patient records were studied to evaluate the treatment outcome, pathology of the tumor, and stage of disease. Finally, the overall survival rate and tumor-free survival of patients was assessed. Results The mean patient age was 53.87± 14.11 years. Most participants had stage I (36.7%) or stage II (35%) disease. Serous adenocarcinoma (57.6%) was the most common pathology found in patients with epithelial ovarian cancer. The overall survival of patients in this study was significantly associated with the histological tumor type (p = 0.000) and disease stage (p = 0.0377). Stage I (84.18%) and serous adenocarcinoma (72.81%) demonstrated the best survival. The tumor-free survival rates were not associated with histology types (p = 0.079), surgical procedure (p = 0.18), or chemotherapy (p = 0.18). Conclusion The survival of patients with epithelial ovarian cancer was significantly associated with disease stage. Serous adenocarcinoma also had the best prognosis among the pathologies studied. Therefore, early detection of ovarian cancer can substantially increase the survival rate. PMID:26516450

    SALL4 is a transcription factor originally identified as a homeotic gene essential for organ development. Early studies suggested that SALL4 is a useful marker to identify testicular and ovarian germ cell tumors. The aim of the study was to evaluate the diagnostic potential of SALL4 immunohistochemistry. Immunohistochemical staining was performed on a tissue microarray (TMA) with 3966 samples from 94 different tumor types and on a further TMA with 492 esophagus carcinomas. SALL4 immunostaining was by far most prevalent and most intensive in testicular tumors with a positivity rate of 93.1 % in seminomas, 80 % in mixed germ cell tumors (embryonic carcinomas/yolk sac tumors), and 18.5 % in teratomas, respectively. However, SALL4 expression is not specific to germ cell tumors. We observed SALL4 positivity in non-germ cell tumors as carcinomas of the kidney (28.9 % of chromophobe, 34.4 % of clear cell carcinoma), in intestinal type adenocarcinoma of the stomach (10.9 %), in adenocarcinoma (10.5 %) and squamous cell carcinoma (7.2 %) of the esophagus, and in malignant melanoma (8.1 %) and invasive urothelial bladder carcinoma (20 %). SALL4 expression was not found in lymphomas, in soft tissue tumors or breast tumors. At analysis of esophagus carcinoma TMA, no significant association was seen between SALL4 expression and overall survival in adenocarcinoma. However, SALL4 expression was strongly associated with worse overall survival in squamous cell carcinoma. SALL4 expression can be found at relevant frequencies in various tumors of different primary sites. SALL4 expression in squamous cell carcinoma of the esophagus may constitute a sign of dedifferentiation leading to poor patient prognosis. PMID:26818834

    Opium use has been associated with higher risk of cancers of the esophagus, bladder, larynx, and lung; however, no previous study has examined its association with gastric cancer. There is also little information on the associations between hookah (water pipe) smoking or the chewing of tobacco products and the risk of gastric cancer. In a case-control study in Golestan Province of Iran, we enrolled 309 cases of gastric adenocarcinoma (118 noncardia, 161 cardia and 30 mixed-location adenocarcinomas) and 613 matched controls. Detailed information on long-term use of opium, tobacco products and other covariates were collected using structured and validated lifestyle and food frequency questionnaires. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were obtained using conditional logistic regression models. Opium use was associated with an increased risk of gastric adenocarcinoma, with an adjusted OR (95% CI) of 3.1 (1.9-5.1), and this increased risk was apparent for both anatomic subsites (cardia and noncardia). There was a dose-response effect, and individuals with the highest cumulative opium use had the strongest association (OR: 4.5; 95% CI: 2.3-8.5). We did not find a statistically significant association between the use of any of the tobacco products and risk of gastric adenocarcinoma, overall or by anatomic subsite. We showed, for the first time, an association between opium use and gastric adenocarcinoma. Given that opium use is a traditional practice in many parts of the world, these results are of public health significance. PMID:23319416

    Serous adenocarcinoma of the cervix (SACC) is a very rare tumor. Our study aimed to characterize the immune profile and human papillomavirus (HPV) status of SACC, in comparison with other serous adenocarcinomas arising in the female genital tract. The pathological specimens obtained from 81 patients with serous carcinoma of the uterine cervix (n = 12), 29 endometrium, 20 ovary and 20 patients with mucinous carcinoma of the uterine cervix were reviewed. We assessed the expression of WT-1, p53, p16, HER2, CEA, and CA125 by immunohistochemistry and HPV DNA by PCR in 12 SACC samples. Their immune profile was compared with that of uterine papillary serous carcinoma (UPSC), ovarian serous adenocarcinoma (OSA), and mucinous endocervical adenocarcinoma (MEA). WT-1 and HER2 were expressed in very few SACC samples (0 and 0%, respectively), but p16, CA125, CEA and p53 were present in 100, 92, 58 and 50%, respectively. The difference in WT-1 expression between SACC and UPSC, MEA is not significant, but SACC differ significantly from OSA (p < 0.01). HPV DNA (type 16 or 18) was detected in 4 of the 12 SACC. The immunophenotype of SACC was similar to UPSC, whereas the frequency of expression of WT-1 was significantly lower in SACC than OSA. It appeared that p53 expression was associated with worse clinical outcome in patients with SACC, and that HPV infection was related to its occurrence. PMID:25370301

    Objectives Ovarian cancer is the fourth leading cause of cancer-related death among women in the US largely due to late detection secondary to unreliable symptomology and screening tools without adequate resolution. Optical coherence tomography (OCT) is a recently emerging imaging modality with promise in ovarian cancer diagnostics, providing non-destructive subsurface imaging at imaging depths up to 2 mm with near-histological grade resolution (10–20 μm). In this study, we developed the first ever laparoscopic OCT (LOCT) device, evaluated the safety and feasibility of LOCT, and characterized the microstructural features of human ovaries in vivo. Methods A custom LOCT device was fabricated specifically for laparoscopic imaging of the ovaries in patients undergoing oophorectomy. OCT images were compared with histopathology to identify preliminary architectural imaging features of normal and pathologic ovarian tissue. Results Thirty ovaries in 17 primarily peri or post-menopausal women were successfully imaged with LOCT: 16 normal, 5 endometriosis, 3 serous cystadenoma, and 4 adenocarcinoma. Preliminary imaging features developed for each category reveal qualitative differences in the homogeneous character of normal post-menopausal ovary, the ability to image small subsurface inclusion cysts, and distinguishable features for endometriosis, cystadenoma, and adenocarcinoma. Conclusions We present the development and successful implementation of the first laparoscopic OCT probe. Comparison of OCT images and corresponding histopathology allowed for the description of preliminary microstructural features for normal ovary, endometriosis, and benign and malignant surface epithelial neoplasms. These results support the potential of OCT both as a diagnostic tool and imaging modality for further evaluation of ovarian cancer pathogenesis. PMID:19481241

    Epidemiological studies have demonstrated associations between endometriosis and certain histotypes of ovarian cancer, including clear cell, low-grade serous and endometrioid carcinomas. We aimed to determine whether the observed associations might be due to shared genetic aetiology. To address this, we used two endometriosis datasets genotyped on common arrays with full-genome coverage (3194 cases and 7060 controls) and a large ovarian cancer dataset genotyped on the customized Illumina Infinium iSelect (iCOGS) arrays (10 065 cases and 21 663 controls). Previous work has suggested that a large number of genetic variants contribute to endometriosis and ovarian cancer (all histotypes combined) susceptibility. Here, using the iCOGS data, we confirmed polygenic architecture for most histotypes of ovarian cancer. This led us to evaluate if the polygenic effects are shared across diseases. We found evidence for shared genetic risks between endometriosis and all histotypes of ovarian cancer, except for the intestinal mucinous type. Clear cell carcinoma showed the strongest genetic correlation with endometriosis (0.51, 95% CI = 0.18-0.84). Endometrioid and low-grade serous carcinomas had similar correlation coefficients (0.48, 95% CI = 0.07-0.89 and 0.40, 95% CI = 0.05-0.75, respectively). High-grade serous carcinoma, which often arises from the fallopian tubes, showed a weaker genetic correlation with endometriosis (0.25, 95% CI = 0.11-0.39), despite the absence of a known epidemiological association. These results suggest that the epidemiological association between endometriosis and ovarian adenocarcinoma may be attributable to shared genetic susceptibility loci. PMID:26231222

    Cavitation in pulmonary metastases is thought to be uncommon. To date, few cases of pulmonary metastases originating from ovarian cancer and showing cavitation have been reported. We report a patient with multiple cavitation in pulmonary metastases from ovarian mucinous cystadenocarcinoma. A 28-year-old woman was admitted to our hospital presenting with cough and fever. The patient had undergone right ovariectomy for ovarian mucinous cystadenocarcinoma at the age of 23 years. Her chest radiograph on admission showed multiple cavities associated with infiltration in both lungs. Histological sections obtained by transbronchial lung biopsy revealed mucus-secreting adenocarcinoma, and a diagnosis of metastatic lung cancer from the ovary was made. Computed tomographic (CT) scans of the chest demonstrated various findings, including multiple thick-walled cavities, thin-walled cavities, air-space consolidations, ground glass opacities, and centrilobular nodular shadows formed by aspiration of the mucinous secretions. It is important to recognize that cavitation can occur in pulmonary metastases from ovarian cancer. PMID:11530393

    The AT-rich interacting domain‑containing protein 1A gene (ARID1A) encodes ARID1A, a member of the SWI/SNF chromatin remodeling complex. Mutation of ARID1A induces changes in expression of multiple genes (CDKN1A, SMAD3, MLH1 and PIK3IP1) via chromatin remodeling dysfunction, contributes to carcinogenesis, and has been shown to cause transformation of cells in association with the PI3K/AKT pathway. Information on ARID1A has emerged from comprehensive genome‑wide analyses with next‑generation sequencers. ARID1A mutations have been found in various types of cancer and occur at high frequency in endometriosis‑associated ovarian cancer, including clear cell adenocarcinoma and endometrioid adenocarcinoma, and also occur at endometrial cancer especially in endometrioid adenocarcinoma. It has also been suggested that ARID1A mutation occurs at the early stage of canceration from endometriosis to endometriosis‑associated carcinoma in ovarian cancer and also from atypical endometrial hyperplasia to endometrioid adenocarcinoma in endometrial cancer. Therefore, development of a screening method that can detect mutations of ARID1A and activation of the PI3K/AKT pathway might enable early diagnosis of endometriosis‑associated ovarian cancers and endometrial cancers. Important results may also emerge from a current clinical trial examining a multidrug regimen of temsirolimus, a small molecule inhibitor of the PI3K/AKT pathway, for treatment of advanced ovarian clear cell adenocarcinoma with ARID1A mutation and PI3K/AKT pathway activation. Also administration of sorafenib, a multikinase inhibitor, can inhibit cancer proliferation with PIK3CA mutation and resistance to mTOR inhibitors and GSK126, a molecular‑targeted drug can inhibit proliferation of ARID1A‑mutated ovarian clear cell adenocarcinoma cells by targeting and inhibiting EZH2.

    At birth, the mammalian ovary contains a finite number of primordial follicles, which once depleted, cannot be replaced. Xenobiotic exposures can destroy primordial follicles resulting in premature ovarian failure and, consequently, early entry into menopause. A number of chemical classes can induce premature ovarian failure, including environmental, chemotherapeutic and industrial exposures. While our knowledge on the mechanistic events that occur in the ovary with chemical exposures is increasing, our understanding of the ovary's capacity to metabolize such compounds is less established. This review will focus on three chemicals for which information on ovarian metabolism is known: trichloroethylene, 7,12-dimethylbenz[a]anthracene and 4-vinylcyclohexene. The current state of understanding of ovarian bioactivation and detoxification processes for each will be described. PMID:21616964

    Breast cancer is the most common malignant tumor in women of reproductive age, and fertility preservation counseling is now an integral part of the initial management of these patients. This article reports the case of a 33-year-old woman diagnosed with breast cancer and referred for oncofertility counseling before her treatment. Despite a previous negative cancer workup, a transvaginal ultrasound scan, performed for antral follicle count as part of the initial ovarian reserve assessment, revealed a synchronous ovarian adenocarcinoma. A BRCA1 mutation was confirmed weeks later. This report highlights the role of transvaginal ultrasound in the initial evaluation and reviews the risks associated with fertility preservation in breast cancer patients. PMID:25386809

    The S100P protein stimulates cell proliferation and survival, thereby contributing to tumor progression. The purpose of this study was to evaluate S100P expression in the three subtypes of mucinous cystic tumors, cystadenomas, borderline tumors, and adenocarcinomas. The authors examined nuclear S100P expression in 60 mucinous ovarian tumor specimens, including 24 specimens of mucinous cystadenoma, 15 of borderline tumors, and 21 of adenocarcinomas. Immunohistochemistry revealed S100P expression followed one of three patterns: (1) Expressed in most nuclei of mucinous epithelial cells, (2) sporadic (spotted or patchy) expression, or (3) absent or rarely expressed in the nuclei of mucinous epithelial cells. Most adenomas showed the first expression pattern, and borderline tumors often showed a patchy expression pattern. Adenocarcinomas generally demonstrated absence of S100P expression. These data suggest that S100P is a useful histological marker to differentiate between benign, borderline, and malignant mucinous tumors of the ovary. PMID:26050349

In a study by one member of the Breast Cancer Consortium of hereditary or familial ovarian cancer in southern Ontario, Canada, the author stated that "our distinction between hereditary and familial ovarian cancer is arbitrary. We have included families with three ovarian cancers or five or more cases of ovarian cancer or breast cancer in the hereditary group" [21]. The U.S. NIH Consensus Conference on Ovarian Cancer in its 1990 report did not define site-specific ovarian cancer in its statement that "less than 0.5% of women are at a significant risk (for the development of ovarian cancer) because of three hereditary ovarian cancer syndromes: (1) breast/ovarian cancer syndrome; (2) site-specific ovarian cancer; and (3) hereditary non-polyposis colorectal cancer (Lynch Syndrome II), colorectal, endometrial, GI, kidney, and ovarian cancer" [22]. With the "arbitrary" definition of site-specific ovarian cancer by the Breast Cancer Consortium and the absence of a definition by the NIH Consensus Conference on Ovarian Cancer, we continue to define familial or site-specific ovarian cancer as two or more first-degree or first- and second-degree relatives with ovarian cancer. As seen in Table 3, it can be very difficult to assess the risk of familial ovarian cancer. PRIMARY PERITONEAL CARCINOMA AFTER PROPHYLACTIC OOPHORECTOMY FOR A FAMILY HISTORY OF OVARIAN CANCER: In 1982, scientists from the National Cancer Institute reported that three women with a familial history of ovarian cancer developed widespread adenocarcinoma "indistinguishable histopathologically from ovarian cancer" 1, 5, and 11 years after undergoing prophylactic oophorectomy [23].

    Polymorphous low-grade adenocarcinomas (PLGA) are distinctive salivary gland neoplasms, with an almost exclusive propensity to arise from the minor salivary glands. PLGA frequently manifests as an asymptomatic, slow-growing mass within the oral cavity, which must be separated from adenoid cystic carcinoma and benign mixed tumor for therapeutic and prognostic considerations. We report a case of a 67-year-old male, who presented with a long-standing mass in the palate. This lesion was diagnosed as PLGA based on histopathological findings, which was further confirmed by the immunohistochemical marker. PMID:26604510

    Synchronous primary endometrial and ovarian cancers are uncommon. The purpose of this study was to evaluate the clinicopathological characteristics, treatment and prognosis of synchronous primary endometrial and ovarian cancers. The clinicopathological characteristics of 43 patients with synchronous primary endometrial and ovarian cancers in the Obstetrics and Gynecology Hospital of Fudan University between 1999 and 2009 were retrospectively reviewed. Our results revealed that the median age at the time of diagnosis was 51 years (range, 29–71). The common presenting symptoms were abnormal uterine bleeding (AUB, 65.12%), abdominal mass (25.58%), abdominal pain and abdominal fullness (39.53%). An elevated CA125 level was observed in the majority of patients (n=20, 76.9%). Endometrioid type accounted for 60.47% of uterine carcinomas and different pathological types, including serous adenocarcinoma, clear cell carcinoma, adenosquamous and acanthoadenocarcinoma, were also identified in synchronous primary endometrial and ovarian cancers. All patients underwent surgical intervention (hysterectomy and bilateral salpingo-oophorectomy with pelvic lymphadenectomy or debulking surgery). The 5-year survival rate was 86.05% and nine patients had recurrence (20.93%). The early stage group (FIGO stages I and II) had more favorable prognosis than the advanced stage group (FIGO stages III and IV; P<0.05). In conclusion, synchronous primary endometrial and ovarian cancers are different from either primary endometrial carcinoma or ovarian cancer and are usually identified at early stages with a good prognosis.

    Decreased E-cadherin expression permits dissociation and widespread dissemination of gastric adenocarcinoma cells. We studied the relationship between paranuclear E-cadherin distribution and the histopathologic characteristics of gastric adenocarcinomas. E-cadherin immunostains of 173 gastric adenocarcinoma sections revealed paranuclear; punctate to vesicular staining in 18% (16/87) of the intestinal-type adenocarcinomas, 30% (17/56) of the diffuse-type adenocarcinomas, and 30% (9/30) of the mired adenocarcinomas. These data suggest that in some gastric adenocarcinomas, there is a defect in transport of E-cadherin to the cell surface, which may prevent intercellular adhesion and encourage dissemination. Of 34 cancers with paranuclear E-cadherin staining, 20 (59%) had paranuclear staining within the nonneoplastic epithelium, but only 22.0% of 100 carcinomas with absent or membranous E-cadherin staining were accompanied by morphologically benign epithelium with paranuclear E-cadherin. In surface epithelium, paranuclear E-cadherin staining colocalized with Griffonia simplicifolia lectin II in the Golgi apparatus. The presence of paranuclear E-cadherin in cancer-associated benign epithelium suggests that the alteration in the E-cadherin molecule responsible for the paranuclear distribution may be an early change in gastric adenocarcinoma progression.

    Gastric-type adenocarcinoma of the uterine cervix (GAS) is a rare variant of mucinous endocervical adenocarcinoma not etiologically associated with human papillomavirus (HPV) infection, with minimal deviation adenocarcinoma (MDA) at the well-differentiated end of the morphologic spectrum. These tumors are reported to have worse prognosis than usual HPV associated endocervical adenocarcinoma (UEA). A retrospective review of GAS was performed from the pathology databases of 3 institutions spanning 20 years. Stage, metastatic patterns, and overall survival were documented. Forty GAS cases were identified, with clinical follow-up data available for 38. The tumors were subclassified as MDA (n=13) and non-MDA GAS (n=27). Two patients were syndromic (1 Li-Fraumeni, 1 Peutz-Jeghers). At presentation, 59% were advanced stage (FIGO II to IV), 50% had lymph node metastases, 35% had ovarian involvement, 20% had abdominal disease, 39% had at least 1 site of metastasis at the time of initial surgery, and 12% of patients experienced distant recurrence. The metastatic sites included lymph nodes, adnexa, omentum, bowel, peritoneum, diaphragm, abdominal wall, bladder, vagina, appendix, and brain. Follow-up ranged from 1.4 to 136.0 months (mean, 33.9 mo); 20/38 (52.6%) had no evidence of disease, 3/38 (7.9%) were alive with disease, and 15/38 (39.5%) died of disease. Disease-specific survival at 5 years was 42% for GAS versus 91% for UEA. There were no survival differences between MDA and non-MDA GAS. GAS represents a distinct, biologically aggressive type of endocervical adenocarcinoma. The majority of patients present at advanced stage and pelvic, abdominal, and distant metastases are not uncommon. PMID:26457350

    Pancreatic metastases are very uncommon and originate most commonly from lung, colon, breast and kidney cancer. Ovarian adenocarcinoma has been reported as a primary site of pancreatic metastasis, but its diagnosis has rarely being reported by endoscopic ultrasound guided fine needle aspiration (EUS-FNA). We report a case of multiple metastases to the pancreas from ovarian carcinoma occurring four years after original resection of the primary tumour. Our patient presented with severe epigastric pain which was initially treated as acute pancreatitis. Further imaging modalities showed multiple large pseudocystic lesions in the pancreatic head and body. Subsequent EUS-FNA confirmed that the lesions were metastatic disease from an advanced ovarian carcinoma. She underwent palliative chemotherapy and the pancreatic lesion showed receding size.

    We describe the case of a presumed metastatic adenocarcinoma discovered in the conjunctival limbus of a 75-year-old male with a history of prostate adenocarcinoma. After an initial clinical diagnosis of pinguecula and unsuccessful topical steroid therapy, the lesion was excised and sent for pathological evaluation and special staining. The histopathological evaluation was consistent with a diagnosis of adenocarcinoma, without evidence of lacrimal tissue. Surprisingly, results from special staining were most consistent with lung adenocarcinoma rather than that from a prostate origin. Systemic radiographic evaluation did not locate the primary tumour, and the patient did not present with any symptoms consistent with malignancy. Watchful waiting was chosen as the therapeutic strategy to manage the patient. This is the first report of an adenocarcinoma, likely metastatic, at the conjunctival limbus. PMID:27190113

    Ovarian mucinous tumors with mural nodules are rare surface epithelial-stromal tumors. The mural nodules are divergent neoplasms that may be benign or malignant. The latter may be in the form of a sarcoma, carcinosarcoma, anaplastic carcinoma, or a variety of other recognized histotypes of carcinoma, which raises the question of whether malignant mural nodules represent a form of dedifferentiation in ovarian mucinous tumors or whether they represent collision tumors. We recently reported the K-RAS gene mutation status in a case of ovarian mucinous adenocarcinoma with mural nodule of high-grade sarcoma. The mucinous and sarcomatous components revealed a mutation in codon 12 of the K-RAS gene of a different nucleotide substitution, indicating that these 2 tumor components were different clones of the same tumor. Herein, we are reporting another case of a 20-yr-old woman who presented with 22 cm pelvic mass, omental caking, and ascites. A diagnosis of invasive mucinous carcinoma with mural nodules of anaplastic carcinoma was rendered. K-RAS gene mutation studies revealed p.G12V, c.35G>T mutation in the 2 components of the tumor, which is the most common mutation reported in mucinous tumors of the ovary. The fact that sarcomatous or anaplastic carcinomatous mural nodules in ovarian mucinous tumors display the same K-RAS mutations as their underlying mucinous neoplasms provides supportive evidence that at least some malignant mural nodules represent a form of dedifferentiation in ovarian mucinous tumors, rather than a collision of 2 divergent tumor types.

    An 8-year-old neutered female Labrador retriever was presented with a 3-year history of intermittent haematuria. Ultrasonographic evaluation of the urinary bladder revealed a 2 × 3 × 0.5 cm intraluminal mass arising at the dome. The mass was excised via partial cystectomy. Histopathological examination revealed neoplastic epithelial cells arranged in sheets, irregularly-branching tubules and acini within a fibrovascular stroma. Neoplastic cells were cuboidal to polygonal with abundant foamy amphophilic cytoplasm, typically with a single, large, clear intracytoplasmic vacuole and eccentric nucleus ('signet ring' cells). Neoplastic tubules were often ectatic and contained abundant mucin. Immunohistochemically, the neoplastic cells had weak, cytoplasmic immunoreactivity for cytokeratin 7 and rare, but strong, nuclear immunoreactivity for CDX2. Based on the cellular morphology, immunolabelling characteristics and anatomical location, a diagnosis of adenocarcinoma of urachal origin was made. To the authors' knowledge, this is the first reported case of urachal adenocarcinoma in a dog. PMID:27009748

    Ovarian vein thrombosis (OVT) is a rare cause of abdominal pain that may mimic a surgical abdomen. It is most often diagnosed during the postpartum period. In this report, we present four cases of postoperative ovarian vein thrombosis. The complications of OVT can be significant, and the diagnosis relies on a careful examination of the radiographic findings. It can occur with lower quadrant abdominal pain, especially in the setting of recent pregnancy, abdominal surgery, pelvic inflammatory disease, or malignancy. Diagnosis can be made with confidence using ultrasound, computed tomography or magnetic resonance imaging. Treatment of ovarian vein thrombosis is particularly important in the post-partum patients, with anticoagulation therapy being the current recommendation. PMID:26526119

    Ovarian cancer is the most deadly gynecologic malignancy, with more than 15,000 deaths anticipated in 2012.1 While approximately 80% of patients will respond to frontline chemotherapy, more than 60% of patients will experience disease recurrence and only 44% will be alive at 5 years.1,2 Host anti-tumor immune responses are associated with a significant improvement in overall survival for women with ovarian cancer.3,4 By bolstering these responses, it may therefore be possible to significantly influence the prognosis of women with this lethal disease. In this review, we will focus on innovative immune-based strategies which are currently being investigated in the treatment of ovarian cancer. PMID:22906947

    A 19-year-old unmarried woman with regular menstrual cycles presented with symptoms of vague abdominal pain of 1 month duration. General condition fair. Per abdomen-a firm, non-tender mass corresponding to 26 weeks of gestation with smooth surface, upper and lateral borders well defined, lower border not palpable was observed. Ultrasonography: left ovarian tumour 28×19 cm with mixed echogenicity was seen in the pelvis extending superiorly into the abdominal cavity with fat, fluid contents, multiple septations. Right ovary measures 6×4 cm with 3.7 cm focal hyperechoic lesion. Uterus anteverted, normal size. No free fluid seen. CT confirmed the ultrasonography findings. Cancer antigen (CA) 125 was 52 IU/mL. Exploratory laparotomy followed by left ovariotomy and salpingectomy and right ovarian cystectomy was performed, leaving behind a significant amount of normal ovarian tissue. Cut section of the gross specimen of the left ovarian tumour-dermoid cyst-plenty of sebaceous fluid and a large tuft of hair. The right ovarian cystectomy revealed a dermoid cyst with hair and pellets of sebum. Histopathology showed bilateral dermoid ovarian cyst. PMID:25012889

    We report a very rare case of Peutz-Jeghers syndrome (PJS) composed of multiple genital tract tumors and mucinous adenocarcinoma. A 46-year-old woman presented to our hospital with lower abdominal pain resulting from PJS involves sex cord tumor with annular tubules (SCTAT), ovarian mucinous tumor, ovarian serous tumor, mucinous adenocarcinoma of colon. The CEA concentration is high before surgery, and decreases after the surgery and subsequent chemoradiotherapy. This case demonstrates a classic clinical presentation of a patient with PJS. PJS patients have increased risk of malignancy and early detection and regular surveillance of the high-risk patients with PJS is crucial. Surgery may be required for obstructive gastrointestinal lesions as well as those exhibiting malignant degeneration. PMID:25120832

    Retroperitoneal mucinous cystadenomas are rare lesions (less than 50 reported) characterized by presence of ovary like stroma of unknown origin. However, germinal component of ovary has never been found in them. The pancreas occasionally gives rise to mucinous cystadenomas, but they are always intrapancreatic. We report a unique case of a rare retroperitoneal mucinous cystadenomas with presence of ovarian follicles in a 45-year-old lady who presented with an abdominal mass. This was successfully excised. Though retroperitoneal mucinous cystadenomas are rare, presence of ovarian follicle (germ cell) in them has never been reported before. PMID:27358520

    Background Primary mucinous adenocarcinomas of the ovary are uncommon and their biologic behavior uncertain. Retrospective studies suggest that many mucinous carcinomas diagnosed as primary to the ovary were actually metastatic from another site. A prospective randomized trial provided an opportunity to estimate the frequency of mucinous tumors, diagnostic reproducibility, and clinical outcomes. Methods A phase III trial enrolled 4000 women with stage III or IV ovarian carcinoma, treated by surgical staging and debulking, with randomization to one of five chemotherapeutic arms. Slides and pathology reports classified as primary mucinous carcinoma were reviewed independently by three pathologists. Cases were re-classified as primary or metastatic to the ovary according to two methods. Overall survival (OS) of reclassified groups was compared with each other and with that of patients with serous carcinomas. Results Forty-four cases were classified as mucinous adenocarcinoma at review. Using either method, only about one third were interpreted by the three reviewers as primary mucinous carcinomas. Reproducibility of interpretations among the reviewers was high with unanimity of opinion in 30 of the 44 (68%) cases. The median survival (MS) did not differ significantly between the groups interpreted as primary or metastatic, but the OS was significantly less than that for women with serous carcinoma (14 vs 42 months, p<0.001). Conclusion Advanced stage mucinous carcinoma of the ovary is very rare and is associated with poor OS. Many mucinous adenocarcinomas that are diagnosed as primary ovarian neoplasms appear to be metastatic to the ovary. PMID:20862744

    Intestinal adenocarcinomas were identified in 76 adult deer from a closed herd of 193 breeding animals grazing pasture heavily infested with bracken fern (Pteridium aquilinum). Tumors were observed postmortem in 32 animals with rapid weight loss, and similar neoplasms were detected in a further 44 clinically normal deer at "cull." Tumors were located in distal ileum, cecum, and proximal colon and presented as single (26%) or multiple (74%), variably sized, pale-gray, firm, poorly circumscribed neoplasms with associated intestinal strictures. Histopathologically tumors were well-differentiated, locally infiltrative, low-grade adenocarcinomas of tubular (51%), mucinous (33.5%), or mixed (15.5%) types. Extraintestinal metastases were not observed. The high incidence of intestinal adenocarcinoma within this herd suggests a specific and novel syndrome, and genetic and/or environmental factors may be involved in the pathogenesis. PMID:24503440

    NFATc1 (nuclear factor of activated T‑cells c1) is associated with malignancy in several cancer models. However, the expression and function of NFATc1 in ovarian cancer remain elusive. In the present study, we investigated the role of NFATc1 in human epithelial ovarian cancer (EOC) using human ovarian adenocarcinoma SKOV3 cells and patient characteristics. NFATc1 expression was silenced by siRNA in the SKOV3 ovarian cancer cell line and in human ovarian cancer nude mouse xenografts. Real‑time PCR, western blotting, immunohistochemical staining, MTT, flow cytometry, transwell, erasion trace and mouse assays were used to detect NFATc1 expression, cell proliferation, apoptosis, cell invasion and migration, tumor growth and angiogenesis. Survival analysis was performed to assess the correlation between NFATc1 expression and survival. NFATc1 was overexpressed in the SKOV3 ovarian cancer cell line and in human serous/mucinous ovarian cancer tissues. The silencing of NFATc1 expression by siRNA reduced cell proliferation and migration and promoted apoptosis in vitro and decreased the ovarian cancer cell tumorigenesis in vivo in nude mice. NFATc1 overexpression in high‑grade serous ovarian carcinomas was an independent prognostic factor of poor overall survival and of early relapse (P<0.01) in a univariate analysis. Our present data provide evidence that NFATc1 is overexpressed in human serous/mucinous ovarian cancer and is associated with a poor prognosis. NFATc1 silencing regulates the cell cycle, apoptosis, invasion and migration. NFATc1 thus has the potential to be a therapeutic target and to be used in EOC diagnosis and prognosis. PMID:27350254

    2012-06-01

    Borderline ovarian tumours account for 10-20% of all epithelial ovarian cancer. Historically, standard primary surgery has included borderline ovarian tumours, omentectomy, peritoneal washing and multiple biopsies. As one-third of borderline ovarian tumours are diagnosed in women under the age of 40 years, fertility-sparing treatment has been more frequently used in the past 10 years. Fertility drugs are well tolerated in women with infertility after fertility-sparing surgery. Careful selection of candidates is necessary. Laparoscopic techniques can be used, but should be reserved for oncologic surgeons. This conservative treatment increases the rate of recurrence, albeit with no effect on survival. The pregnancy rate is nearly 50%, and most are achieved spontaneously. These women should be closely followed up. The question is whether this is acceptable from a gynaecologic oncologic point of view. For this reason, we will discuss recently published studies and gynaecologic oncologic concerns about the mode of fertility-sparing surgery and its consequences. PMID:22321906

    Objective of this article is to appraise diagnostic aspects and treatment modalities in childhood ovarian tumor in background of available evidence. Literature search on Pubmed revealed various aspects of epidemiology, histopathological diagnosis, and treatment of pediatric ovarian tumor. 85 % of childhood tumors are germ cell tumors. The varied histopathological picture in germ cell tumors poses a diagnostic and therapeutic challenge. Immunohistochemistry and newer genetic markers like SALL4 and karyopherin-2 (KPNA2) have been helpful in differentiating ovarian yolk sac tumor from dysgerminoma, teratomas, and other pictures of hepatoid, endometrioid, clear cell carcinomatous, and adenocarcinomatous tissues with varied malignant potential. Before platinum therapy, these tumors were almost fatal in children. Fertility-conserving surgery with bleomycin, etoposide, and cisplatin has dramatically changed the survival rates in these patients. This modality gives cancer cure with healthy offspring to female patients with childhood ovarian tumor. Evidence also supports this protocol resulting in successful pregnancy rates and safety of cytotoxic drugs in children born to these patients. PMID:24757335

    2016-07-01

    Here, we present a rare case of intestinal type adenocarcinoma arising in mature cystic teratoma (MCT) and review all previously reported similar cases with emphasis on the immunohistochemical characteristics of prior cases. Nine prior cases of intestinal type adenocarcinoma arising in MCT have been previously reported. Two of the prior cases as well as this case have been associated with CA19-9 elevation. CK20 is consistently strongly positive and CK7 is usually negative in cases of intestinal type adenocarcinoma arising in MCT. This contrasts with mucinous tumors of the ovary which are known to be usually CK7 strongly positive and inconsistently CK20 positive. The pattern of strong CK20 staining and often negative or weak CK7 staining is common to mucinous neoplasms arising in MCT. These findings suggest that the less common subset of primary mucinous ovarian tumors that have strong CK20 staining and partial or negative CK7 staining may represent a group of tumors with germ cell origin rather than the more common surface epithelial origin.

    Background Mature cystic teratomas (MCTs) are the most common germ cell tumors of the ovary. Malignant tranformation occurs in 1-2% of these neoplasms. Although most of the malignancies arising from MCTs are squamous cell carcinomas, adenocarcinoma of the gastrointestinal type is extremery rare. We herein present a case of adenocarcinoma of the intestinal type arising from a MCT. Case A 49-year-old female underwent surgery for a left ovarian tumor. The histology of the cyst walls revealed a MCT with a few hair shafts and a squamous layer, while another part of the tumor showed adenocarcinoma of the intestinal type. Five years after surgery, she is alive without disease. PMID:23216975

    Pancreatic ductal adenocarcinoma is characterized by a poor prognosis and a low median survival, despite improvements observed for many other solid tumours. Intensive research efforts have been undertaken during the last decades to discover new prognostic and treatment predictive biomarkers for pancreatic ductal adenocarcinoma. The mainstay of medical treatment for the disease has been the well-tolerated nucleoside analogue, gemcitabine. The only targeted agent currently used in pancreatic ductal adenocarcinoma patients is the epithelial growth factor receptor inhibitor erlotinib in combination with gemcitabine. Recently, treatment regimens such as a combination of fluorouracil-leucovorin-irinotecan-oxaliplatin (FOLFIRINOX) and the combination of nab-paclitaxel with gemcitabine have been introduced for metastatic pancreatic ductal adenocarcinoma. Although these treatment regimens significantly improve survival of patients, there are no good predictive biomarkers available that can be used to identify who would benefit most from them. Therefore, the search for predictive biomarkers that would facilitate personalization of chemotherapy is highly relevant. PMID:26769569

    Over the past three decades, the incidence of lung adenocarcinoma has increased worldwide. Most individuals with lung adenocarcinoma (especially women) are nonsmokers. Reported risk factors for the development of lung adenocarcinoma include cigarette smoking; exposure to cooking fumes, air pollution, second-hand smoke, asbestos, and radon; nutritional status; genetic susceptibility; immunologic dysfunction; tuberculosis infection; and asthma. Human papillomavirus (HPV) infection is a known risk factor for the development of squamous cell carcinoma (SCC), but it has not been thoroughly assessed as a potential risk factor for the development of pulmonary adenocarcinoma. More than 50% of people are infected with HPV during their lifetimes, either via intrauterine or postnatal infection. Recent studies involving Taiwanese patients have demonstrated a possible association between HPV infection and the risk of developing pulmonary adenocarcinoma. HPV transmission pathways have not yet been conclusively identified. The observation of certain types of HPV in association with cervical and oral SCC raises the possibility of sexual transmission of HPV from the cervix to the oral cavity, with subsequent transmission to the larynx and then to the lung. HPV infection and metaplasia in lung tissue may increase an individual's susceptibility to the tumorigenesis of pulmonary adenocarcinoma. Further epidemiologic and pathologic investigations will be necessary to establish a causal relation. PMID:15368331

    In the report, we describe the first case of laparoscopic ovarian transposition prior to pelvic radio-chemo therapy in a young female patient with advanced rectal cancer in Japan. A 14-year-old female visited a hospital because of consistent diarrhea and melena. Colonoscopy examination showed a bulky tumor of the rectum, which was diagnosed as moderately to poorly differentiated adenocarcinoma. The diagnosis was cT3N2aM1a (due to lymph node in pelvic side wall), cStage IVA. In an attempt to improve local control and sphincter preservation, neoadjuvant concurrent radio-chemo therapy was planned. Considering that pelvic irradiation particularly in young female might cause ovarian failure, laparoscopic ovarian transposition was carried out prior to pelvic irradiation. Sequentially the patient underwent low anterior resection of the rectum and lymphadenectomy including pelvic side wall. The menstruation was maintained with delay for 6 months after adjuvant chemotherapy. There is no evidence of cancer recurrence at 3 years after the surgery.In premenopausal patients with rectal cancer undergoing pelvic irradiation, laparoscopic ovarian transposition is one of the choices to prevent ovarian failure.

    Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) is a cell-cell adhesion receptor and is implicated in several cellular functions. It is rarely reported in ovarian tumors. The aim of this study is to determine the expression of CEACAM1 in ovarian tumors, trying to see whether CEACAM1 has different expression patterns as a function of histotype. Antigen expression was examined by immunohistochemistry with mouse anti-human antibody for CEACAM1. Immunohistochemistry was performed using avidin-biotin-diaminobenzide staining. The results were expressed as average score ± SD (0, negative; 8, highest) for each histotype. In ovarian tumors, the benign serous and mucinous cystadenoma negatively or weakly expressed CEACAM1, the malignant epithelial tumors strongly expressed CEACAM1, and there was significant difference between benign epithelial tumor and adenocarcinoma (P < .05). The well-differentiated serous adenocarcinoma expressed CEACAM1 mainly with membrane pattern, and the intermediately and poorly differentiated serous adenocarcinomas expressed CEACAM1 mainly with cytoplasmic pattern (P < .05). In addition, CEACAM1 expression is elevated in solid tumors of ovary but variable as a function of histotype. Compared with membranous expression, the cytoplasmic expression was observed almost in metastatic carcinoma that might decrease the adhesive interactions of the carcinoma cells with the surrounding cells, especially with tumor cells, and this could facilitate the tumor cells to metastasize to distant regions. So, we thought that cytoplasmic CEACAM1 might play an important role in tumor progression, especially in tumor metastasis. PMID:26653024

It indicates a reduction in quantity and quality of oocytes in women of reproductive age group. It may be age related as seen in advanced years of reproductive life or may occur in young women due to diverse etiological factors. Evaluating ovarian reserve and individualizing the therapeutic strategies are very important for optimizing the success rate. Majority or women with POR need to undergo in vitro fertilization to achieve pregnancy. However, pregnancy rate remains low despite a plethora of interventions and is associated with high pregnancy loss. Early detection and active management are essential to minimize the need for egg donation in these women. PMID:27382229

    Primary ovarian insufficiency (POI), also known as premature ovarian failure or premature menopause, is defined as cessation of menstruation before the expected age of menopause. Potential etiologies for POI can be divided into genetic, autoimmune, and iatrogenic categories. This review will try to summarize the genetic basis of POI focusing on recent data that are available using newer genetic techniques such as genome-wide association studies, whole-exome sequencing (WES), or next-generation sequencing techniques. By using these techniques, many genes have arisen that play some role in the pathophysiology of POI. Some of them have been replicated in other studies; however, the majority has not been proven yet to be unequivocally causative through functional validation studies. Elucidating the genetic and molecular basis of POI is of paramount importance not only in understanding ovarian physiology but also in providing genetic counseling and fertility guidance. Once additional variants are detected, it might become possible to predict the age of (premature) menopause in women at risk for POI. Women having certain perturbations of POI can be offered the option of oocyte cryopreservation, with later thawing and use in assisted reproductive technology at an appropriate age. PMID:27513024

    In this study, we compared the immunoreactivities of Bcl-2, Bax and p53 proteins in ovarian tumors and related the immunohistochemical findings to the histological type of the tumors. Formalin-fixed, paraffin wax-embedded tissue sections from 40 patients who had serous-mucinous borderline tumors and serous-mucinous adenocarcinoma of the ovary (n=10 each) were stained with hematoxylin-eosin (H&E). After histopathological examination, serial sections were stained immunohistochemically with primary antibodies to Bcl-2, Bax and p53 using an avidin-biotin-peroxidase method. A semi-quantitative grading system was used to compare the immunohistochemical staining intensities. The nuclear DNA fragmentation of apoptosis was determined using TUNEL method. As a result of immunohistochemical staining, increased immunoreactivity of Bcl-2 was observed in adenocarcinomas when compared to borderline tumors (P<0.001). Strong immunoreactivity of Bcl-2 and mild immunoreactivities of Bax and p53 were detected in ovarian adenocarcinomas. There were no significant statistical differences in the immunoreactivity of Bax among the histological type of ovarian tumors. Whereas a balance was observed between the immunoreactivities of Bcl-2 and Bax in the borderline cases, and this balance was strongly changed toward the anti-apoptotic Bcl-2 protein in patients with adenocarcinoma. TUNEL staining of sections indicated apoptotic cells in the serous borderline tumors were about 8-fold higher than in the serous adenocarcinoma. The results of this study on apoptosis-related factors might help to develop novel protective and therapeutic approaches, such as isoflavonoids and isothiocyanates, which were associated with decreased Bcl-2/Bax ratio, against the malignant epithelial ovarian tumors.

    Abstract Several uncommon primary pancreatic tumors, inflammatory conditions, metastasis to the pancreas and peripancreatic masses can mimic the appearance of pancreatic ductal adenocarcinoma (PDA). Differentiation between these lesions and PDA can be challenging, due to the overlap in imaging features; however, familiarity with their typical imaging features and clinical presentation may be helpful in their differentiation, as in some cases, invasive diagnostic tests or unnecessary surgery can be avoided. The different pathologies that can mimic PDA include inflammatory conditions such as the various forms of pancreatitis (chronic-focal mass-forming, autoimmune and groove pancreatitis), pancreatic neuroendocrine tumors, solid pseudopapillary tumors, metastasis (solid non-lymphomatous and hematologic), congenital variants (annular pancreas), as well as peripancreatic lesions (accessory spleen, adrenal masses, duodenal masses, lymph nodes and vascular lesions), and certain rare pancreatic tumors (e.g., acinar cell tumors, solid serous tumors, hamartoma and solitary fibrous tumors). The clinical presentation and imaging features of the most commonly encountered mimics of PDA are discussed in this presentation with representative illustrations. PMID:24060833

    The mortality rate of ovarian cancer remains high due to late diagnosis and recurrence. A fundamental step toward improving detection and treatment of this lethal disease is to understand its origin. A growing number of studies have revealed that ovarian cancer can develop from multiple extra-ovarian origins, including fallopian tube, gastrointestinal tract, cervix and endometriosis. However, the mechanism leading to their ovarian localization is not understood. We utilized in vitro, ex vivo, and in vivo models to recapitulate the process of extra-ovarian malignant cells migrating to the ovaries and forming tumors. We provided experimental evidence to support that ovulation, by disrupting the ovarian surface epithelium and releasing chemokines/cytokines, promotes the migration and adhesion of malignant cells to the ovary. We identified the granulosa cell-secreted SDF-1 as a main chemoattractant that recruits malignant cells towards the ovary. Our findings revealed a potential molecular mechanism of how the extra-ovarian cells can be attracted by the ovary, migrate to and form tumors in the ovary. Our data also supports the association between increased ovulation and the risk of ovarian cancer. Understanding this association will lead us to the development of more specific markers for early detection and better prevention strategies. PMID:25135607

    Anticancer drug sensitivity affects prognosis in ovarian carcinoma. Previously, we purified spectrin αII and βII tetramers from cisplatin-resistant ovarian serous adenocarcinoma cells and demonstrated that they contribute to platinum anticancer drug resistance. In this clinical study, we focused on the role of spectrin αII expression. It is our objective to demonstrate the potential of spectrin αII expression as a useful predictor of anticancer drug resistance and postoperative prognosis in epithelial ovarian carcinoma. Spectrin αII expression in the ovarian adenocarcinoma surgical specimens of 193 patients was examined by immunohistochemical staining. Staining strength was scored 3+, regarded as positive expression, and 2+, 1+, and 0, regarded as non-positive expression. Prognoses obtained from clinical records were evaluated by statistical analysis. In the 193 cases studied, positive spectrin αII expression was associated with worse overall survival when compared with non-positive expression (P < 0.001 by log-rank test), and spectrin αII expression was identified as an independent predictive factor of overall survival (hazard ratio[HR]: 3.77, 95% confidence interval[CI]: 1.77-8.00; P < 0.001 by multivariate Cox's proportional hazards model). In the study about progression-free survival, spectrin αII expression was not associated with prognoses. However, similar results as overall survival were obtained for survival after recurrence of the 92 recurrent cases (P = 0.0051 by log-rank test, HR: 4.49, 95% CI: 2.06-9.79; P < 0.001 by multivariate Cox's proportional hazards model). In a detailed overall survival study of 66 serous adenocarcinoma patients and 127 nonserous adenocarcinoma patients, similar results were also obtained. Spectrin αII expression is a useful predictor of anticancer drug resistance and postoperative prognosis in epithelial ovarian carcinoma.. PMID:26993048

    Malignant tumors with mixed glandular and neuroendocrine characteristics with at least 30% of each component are classified as mixed adenoneuroendocrine carcinoma (MANEC) by the World Health Organization 2010 classification. We report here a case of very well-differentiated adenocarcinoma accompanied by carcinoid tumor, categorized as MANEC. A 41-year-old Japanese man was clinically diagnosed with ascending colon cancer and underwent right hemicolectomy. Using an immunohistologic technique, the pathologic diagnosis was very well-differentiated adenocarcinoma accompanied by carcinoid tumor and marked eosinophil infiltration, which was categorized as MANEC. By immunohistochemical analysis, tumor cells of the carcinoid component exhibited very low proliferation activity. Our case was thought to be MANEC without high malignant potential. MANEC as per the World Health Organization 2010 classification seems to include tumors with diverse grades of malignancy, and it might need to have subclassifications according to the malignancy potential of the tumor cells.

    Multicellular 3D cancer cell culture (spheroids) resemble to in vivo tumors in terms of shape, cell morphology, growth kinetics, gene expression and drug response. However, these characteristics cause very limited drug penetration into deeper parts of the spheroids. In this study, we used multi drug resistant (MDR) ovarian cancer cell spheroid and in vivo tumor models to evaluate the co-delivery of paclitaxel (PCL) and a potent NF-κB inhibitor curcumin (CUR). PCL and CUR were co-loaded into the polyethylene glycol-phosphatidyl ethanolamine (PEG-PE) based polymeric micelles modified with Transferrin (TF) as the targeting ligand. Cytotoxicity, cellular association and accumulation into the deeper layers were investigated in the spheroids and compared with the monolayer cell culture. Comparing to non-targeted micelles, flow cytometry and confocal imaging proved significantly deeper and higher micelle penetration into the spheroids with TF-targeting. Both in monolayers and spheroids, PCL cytotoxicity was significantly increased when co-delivered with CUR in non-targeted micelles or as single agent in TF-targeted micelles, whereas TF-modification of co-loaded micelles did not further enhance the cytotoxicity. In vivo tumor inhibition studies showed good correlation with the 3D cell culture experiments, which suggests the current spheroid model can be used as an intermediate model for evaluation of co-delivery of anticancer compounds in targeted micelles.

    The aim of this study was to discuss the diagnostic and therapeutic dilemmas in cases of pregnant women with adnexal masses, reporting an interesting case with synchronous literature review. The patient, a gravida 2, para 1, 37 year-old woman was diagnosed with a large unilateral adnexal lesion during a scheduled third trimester ultrasound assessment. A large papillary papule with a network of blood vessels showing decreased resistance in blood flow was noticed as well. Surgical intervention revealed ascitic fluid and a large cystic mass arising from the right ovary. Cesarean section and right salpingooophorectomy, including the mass, were performed. Frozen section biopsy was positive for malignancy. Total hysterectomy and left salpingo-oophorectomy, total omentectomy, biopsies from the pelvic peritoneum, pelvic/para-aortic lymphadenectomy and appendicectomy followed. Histology showed mucinous ovarian adenocarcinoma Grade I Stage Ic according to FIGO classification. Surgical intervention, in cases of persisting adnexal lesions, is often necessary, even during pregnancy. PMID:24841681

    The relation of noncontraceptive estrogen use to epithelial ovarian cancer was evaluated in a case-control study conducted in hospitals mainly in the northeastern United States. There were 377 cases diagnosed within the year before hospital admission and 2,030 hospital controls; data were collected by interview in the hospital. Compared with women who never took noncontraceptive estrogens, the overall relative risk estimate for women whose estrogen use lasted at least one year and was not combined with progestogens or testosterone was 1.2 (95% confidence interval (CI) 0.8-1.9), after taking into account risk factors for ovarian cancer. There were 55 cases of the endometrioid, clear cell, or malignant mixed mesodermal cell type; the corresponding relative risk estimate was 0.9 (95% CI 0.3-3.0). There were 26 cases of undifferentiated cell type, with a relative risk estimate of 3.6 (95% CI 1.2-11). Relative risk estimates were similar in a subset of the cases (57%) for which pathology slides were reviewed. For estrogen use of long duration, use of high-dose preparations, or use in the distant past, the relative risk estimates were not significantly different from 1.0. The estimates were elevated for some categories of use, but not consistently--for example, for an interval of 5-9 years since estrogen use began (relative risk (RR) = 2.7), but not after shorter or longer intervals, and for use of conjugated estrogens with a dose of 0.3 mg (RR = 3.2) or 1.25 mg (RR = 2.4), but not for doses of 0.625 mg or 2.5 mg. The relative risk estimate was also elevated for use by nulliparous women (RR = 2.4). The results suggest that, overall, noncontraceptive estrogen use is not associated with the risk of epithelial ovarian cancer. Furthermore, our data do not support the hypothesis that estrogens increase the risk of endometrioid ovarian cancer. The elevated estimates could be due to multiple stratification of the data, but they should be explored in further studies, given the

    A cell strain (FU-GBC-1) was established from cancerous ascites of a 68-year-old male patient with well-differentiated adenocarcinoma of the gallbladder. By light and electron microscopy, the cultured cells showed the morphologic features of adenocarcinoma characterized by gland-like structures, intracellular microcystic spaces, and mucous production. Immunoperoxidase stains showed that FU-GBC-1 cells expressed several epithelial tumor antigens including CA 19-9, carcinoembryonic antigen (CEA), and epithelial membrane antigen (EMA). The cell strain has been in continuous culture up to passage 44 for 1 1/2 years, with the population doubling time of 120 hours. The cytogenetic analysis by a G-band technique showed a constant loss of chromosome Y in FU-GBC-1 cells. The modal chromosome number at passage 12 was 82 with a range of 77 to 85. Flow cytometry with an ethidium bromide technique additionally confirmed aneuploid DNA content (4C) in the cultured cells at passage 12 and 35. Inoculation of FU-GBC-1 cells into the dermis of BALB/c nude mice produced transplantable adenocarcinoma identical to the original tumor. Because no continuous cell lines of the well-differentiated type of gallbladder adenocarcinoma have been reported in the literature currently, the newly established cell strain we report may yield a useful system for studying the morphologic and biologic characteristics of gallbladder adenocarcinoma.

    The relation between various risk factors and adenocarcinoma of the lung was evaluated in a case-control study. Subjects were selected from the Colorado Central Cancer Registry from 1979-1982 in the Denver metropolitan area. A total of 102 (50 males and 52 females) adenocarcinoma case interviews and 131 (65 males and 66 females) control interviews were completed. The control group consisted of persons with cancers of the colon and bone marrow. The risk estimates associated with cigarette smoking were significantly elevated among males (odds ratio (OR) = 4.49) and females (OR = 3.95) and were found to increase significantly (p less than 0.01) with increasing levels of cigarette smoking for both males and females. For adenocarcinoma in females, the age- and smoking-adjusted odds ratios at different levels of passive smoke exposure followed an increasing overall trend (p = 0.05). After additional adjustment for potential confounders, prior cigarette use remained the most significant predictor of risk of adenocarcinoma among males and females. Analysis restricted to nonsmoking females revealed a risk of adenocarcinoma of 1.68 (95% confidence interval (Cl) = 0.39-2.97) for passive smoke exposure of four or more hours per day. Neither sex showed significantly elevated risk for occupational exposures, although males bordered on significance (OR = 2.23, 95% Cl = 0.97-5.12). The results suggest the need to develop cell type-specific etiologic hypotheses.

    In the past two decades, more than 20 viruses with selective tropism for tumor cells have been developed as oncolytic viruses (OVs) for treatments of a variety of malignancies. Of these viruses, eleven have been tested in human ovarian cancer models in preclinical studies. So far, nine phase I or II clinical trials have been conducted or initiated using four different types of OVs in patients with recurrent ovarian cancers. In this article, we summarize the different OVs that are being assessed as therapeutics for ovarian cancer. We also present an overview of recent advances in identification of key genetic or immune-response pathways involved in tumorigenesis of ovarian cancer, which provides a better understanding of the tumor specificities and oncolytic properties of OVs. In addition, we discuss how next-generation OVs could be genetically modified or integrated into multimodality regimens to improve clinical outcomes based on recent advances in ovarian cancer biology.

    This paper will focus on knowledge related to brain metastases from ovarian carcinoma. So far, less than 600 cases were documented in the literature with an incidence among ovarian carcinoma patients ranging from 0.29% to 11.6%. The ovarian carcinoma was usually an advanced-stage epithelial serous carcinoma, and the median interval between diagnosis of ovarian carcinoma and brain metastases was 2 years. Most often, brain metastases, affected the cerebrum, were multiple and part of a disseminated disease. Treatment of brain metastasis has evolved over the years from whole brain radiotherapy (WBRT) only to multimodal therapy including surgical resection or stereotactic radiosurgery followed by WBRT and/or chemotherapy. The median survival after diagnosis of brain metastases was 6 months; nevertheless, a significantly better survival was achieved with multimodal therapy compared to WBRT only. It is suggested that brain imaging studies should be included in the followup of patients after treatment for ovarian carcinoma. PMID:22191058

    Background: Ovarian transposition is the anatomical relocation of the ovaries from the pelvis to the abdomen. Transposition is beneficial in women who are to undergo pelvic radiation, because it allows maintenance of ovarian function and preservation of assisted reproductive capacity. Methods: The da Vinci surgical system (Intuitive Surgical™, Mountainview, CA, USA) was used to perform an endoscopic ovarian transposition. The ovaries were mobilized on their respective infundibulopelvic ligaments and sutured to the ipsilateral pericolic gutters. Results: A series of laboratory sessions using the da Vinci system was completed at our institution's training facility. Surgical experience included cadaveric pelvic dissection and abdominopelvic procedures on anesthetized porcine models. Additional didactic and laboratory training, including a certification examination, was obtained from Intuitive Surgical, Inc. The first clinical case of robotically assisted endoscopic ovarian transposition was performed. Conclusions: Robotically assisted endoscopy was successfully used for ovarian transposition.

    Introduction The issue of conserving the ovaries at hysterectomy in premenopausal women with benign gynecologic disease has been the subject of considerable controversy. Some clinicians prefer prophylactic oophorectomy in premenopausal women during hysterectomy to prevent future development of malignant changes in conserved ovaries. Other clinicians prefer to conserve apparently normal ovaries, because bilateral oophorectomy in premenopausal women results in an abrupt imbalance, sudden onset of menopausal symptoms, decreased libido, increased cardiovascular risk and osteoporosis. Material and methods Two hundred and twenty multipara women (who had completed their families), with benign uterine pathology were included in this prospective study for abdominal hysterectomy with bilateral ovarian preservation. Pre-operative vaginal ultrasound, Doppler studies, diagnostic hysteroscopy and endometrial biopsy were done followed by laboratory studies including Anti-mullerian hormone (AMH), follicle stimulating hormone (FSH) and estradiol for all studied women. Doppler studies, AMH, FSH and estradiol were repeated 6 and 12 months post-operative for assessment of the ovarian function and ovarian blood supply after hysterectomy. Results Pre-operative AMH, FSH and estradiol of the studied women were statistically insignificant compared to AMH, FSH and estradiol 6 and 12 months post-operative. Twelve months post-operative right and left ovarian volumes (6.92 ± 0.18 and 6.85 ± 0.19 cm3, respectively) were significantly larger than pre-operative right and left ovarian volumes (6.19 ± 0.22 and 5.86 ± 0.23 cm3, respectively), and, 12 months post-operative right and left ovarian pulsatility indices (2.92 ± 0.15 and 2.96 ± 0.16 cm/s, respectively) were significantly lower than pre-operative right and left ovarian pulsatility indices (3.45 ± 0.19 and 3.36 ± 0.2 cm/s, respectively).

    Background Ovarian adenocarcinoma is not generally discovered in patients until there has been widespread intraperitoneal dissemination, which is why ovarian cancer is the deadliest gynecologic malignancy. Though incompletely understood, the mechanism of peritoneal metastasis relies on primary tumor cells being able to detach themselves from the tumor, escape normal apoptotic pathways while free floating, and adhere to, and eventually invade through, the peritoneal surface. Our laboratory has previously shown that the Golgi glycosyltransferase, ST6Gal-I, mediates the hypersialylation of β1 integrins in colon adenocarcinoma, which leads to a more metastatic tumor cell phenotype. Interestingly, ST6Gal-I mRNA is known to be upregulated in metastatic ovarian cancer, therefore the goal of the present study was to determine whether ST6Gal-I confers a similarly aggressive phenotype to ovarian tumor cells. Methods Three ovarian carcinoma cell lines were screened for ST6Gal-I expression, and two of these, PA-1 and SKOV3, were found to produce ST6Gal-I protein. The third cell line, OV4, lacked endogenous ST6Gal-I. In order to understand the effects of ST6Gal-I on cell behavior, OV4 cells were stably-transduced with ST6Gal-I using a lentiviral vector, and integrin-mediated responses were compared in parental and ST6Gal-I-expressing cells. Results Forced expression of ST6Gal-I in OV4 cells, resulting in sialylation of β1 integrins, induced greater cell adhesion to, and migration toward, collagen I. Similarly, ST6Gal-I expressing cells were more invasive through Matrigel. Conclusion ST6Gal-I mediated sialylation of β1 integrins in ovarian cancer cells may contribute to peritoneal metastasis by altering tumor cell adhesion and migration through extracellular matrix.

    Some bioactive peptides derived from natural resources or synthesized by rational design have been proved to have very good anticancer effect. We studied the inhibition of PGPIPN, a hexapeptide derived from bovine β-casein, on the invasion and metastasis of human ovarian cancer cells in vitro and its molecular mechanism. The human ovarian cancer cells studied include the cell line SKOV3 as well as the primary ovarian cancer cells from ovarian tumor tissues of 37 patients at initial debulking surgery, diagnosed as serous ovarian adenocarcinoma. We showed that PGPIPN inhibited the invasion of ovarian cancer cells with Transwell chamber assay, the migration of ovarian cancer cells with cell scratch assay and colony formation of ovarian cancer cells. The expression (mRNAs and proteins) of genes relevant to invasion and metastasis, MTA1, and NM23H1 were analyzed by real-time PCR and western blotting. PGPIPN repressed the expression of MTA1, and promoted NM23H1. The effects of PGPIPN were dose-dependent. Thus, our study suggests that PGPIPN is a potential therapeutic agent for adjuvant therapy of human malignant ovarian tumors. PMID:26893013

    Hydrosalpinx in postmenopausal woman is rare. Most commonly it is due to primary ovarian malignancy with fallopian tube involvement or primary fallopian tube carcinoma. But hydrosalpinx with no malignancy in the fallopian tube, associated with synchronous malignancy of ovary and endometrium is rare. In a postmenopausal women, hydrosalpinx is commonly due to fallopian tube malignancy or rarely pelvic inflammatory disease. We present a rare and very interesting case of 65-year-old nulliparous postmenopausal women with bilateral hydrosalpinx and pyometra who was found to have papillary serous adenocarcinoma of the ovary and endometroid adenocarcinoma of endomertrium with normal fallopian tube. One should always suspect genital malignancy with this presentation, especially in this age group.

    The method of ultrasonography is high informative and widely used in diagnostics of ovarian hyperandrogenaemia. The majority of authors consider that a hyperplasia of a stroma is the main pathognomonic marker of polycystic ovaries (PCO). Still recently swell of a stroma was valued visually, that had subjective nature. We offer for the first time a way of diagnostics of stromal hyperplasia grounded on measurement of a volume of a stroma and ovary with ultrasound method, calculation of the ratio of a volume of the ovary to a volume of a stroma for every patient.

    The procedures used for programming and ovarian stimulation in GIFT are identical to those used for in-vitro fertilization. At the Baudelocque Hospital, the hypophyseal gonadal axis is suppressed by administering a gonadotrophin-releasing hormone analogue (Decapeptyl, D-Trp-6-LHRH). Programming for the week of GIFT is then possible by controlling three stages: the beginning of treatment, which is independent of the date of the patient's period, the duration of treatment, which has 5 days' maximum variation, and an end-point of suppressing the spontaneous LH surge.

    Primary ovarian lymphoma is a rare entity. We submit a case of a 34-year-old black patient presenting with a bilateral adnexal tumor. She underwent hysterectomy with double salpingo-oophorectomy followed by polychemotherapy treatment. Histology confirmed Epstein-Barr virus-positive bilateral Burkitt's lymphoma. The patient died from septic shock after a month of treatment. Endemic Burkitt's lymphoma has a predilection for the female genital tract, manifesting itself clinically as a pelvic mass and less frequently as a menstrual disorder. It is a rare entity in our environment but should be kept in mind when treating patients of African origin. PMID:19480266

    Malignant transformation or recurrence of intracranial mature teratoma is an extremely rare occurrence, compared to the usual ovarian counterpart. Previously, yolk sac tumor elements have been considered to be selective progenitors of enteric-type adenocarcinoma arising from intracranial germ cell tumors. However, the present case demonstrates the occurrence of enteric-type adenocarcinoma in recurrent intracranial mature cystic teratoma 12 years after gross total removal, a case of which has not previously been documented in the literature. The 11.5-cm long, dura mater-based tumor on the right fronto-temporal lobe displaced the brain; however, the patient had no neurologic symptoms or discomfort other than pus-like discharge on the scalp. Microscopic examinations revealed a small focus of adenocarcinoma and dysplastic colonic mucosa in the mature cystic teratoma. No immature elements were seen. The cystic wall was almost denuded and showed an exuberant xanthogranulomatous reaction with foreign-body type giant cells engulfing keratin materials and cholesterol clefts, suggesting that chronic inflammation due to repeated cyst wall rupture and the previous resection may contribute to malignant transformation. The adenocarcinoma showed strong immunohistochemical expression of CK20 and p53, but CK7 in patches. The molecular profile of the adenocarcinoma showed a mutation in KRAS and wild-type BRAF, which might be associated with malignant transformation of intracranial mature teratomas. In conclusion, the intracranial mature teratomas should require long-term follow-up, and clinicians, radiologists and pathologists should be aware of the potential for malignant progression of recurrent intracranial mature cystic teratoma despite gross total resection and no neurologic symptoms.

    Ovarian yolk sac tumors are germ cell tumors that usually present in children and young women. Rarely, these tumors can arise in older women, usually in conjunction with surface epithelial tumors, suggesting divergent differentiation from the latter. The combination of mixed ovarian yolk sac tumor and high-grade serous carcinoma is rare, with only one case documented in the literature. We present a case of mixed ovarian yolk sac tumor and high-grade serous carcinoma in a postmenopausal woman, including a brief discussion of the immunohistochemical findings and differential diagnosis. Despite the rarity of mixed ovarian yolk sac tumor and surface epithelial tumors, it is important to recognize the biphasic nature of the tumor, which should prompt a thorough immunohistochemical evaluation. The therapeutic and prognostic implications of proper diagnosis cannot be overemphasized. PMID:26782153

    A case-control study of 150 ovarian cancer patients under the age of 50 and individually matched controls was done to study the influence of fertility and oral contraceptive use on the risk of ovarian cancer. The risk decreased with increasing numbers of live births, with increasing numbers of incomplete pregnancies, and with the use of oral contraceptives. These three factors can be amalgamated into a single index of protection--"protected time"--by considering them all as periods of anovulation. The complement of protected time--viz., "ovulatory age", the period between menarche and diagnosis of ovarian cancer (or cessation of menses) minus "protected time"--was strongly related to risk of ovarian cancer. Other factors found to be associated with increased ovarian cancer risk were obesity, cervical polyps, and gallbladder disease. Women who had an "immediate" intolerance to oral contraceptive use had a fourfold increased risk of ovarian cancer. 7 patients, but no controls, could recall a family history of ovarian cancer.

    A 22-year-old woman first presented in 2009 with abdominal distention. The diagnosis of stage IA right ovarian tumour was made by fertility-sparing surgery. In the subsequent years, the involvement of the left ovary and metastasis to the lungs prompted further surgical intervention and chemotherapy. By 2013, she experienced insidious, debilitating and diffuse musculoskeletal pain with trismus. Polymyositis or diffuse radiculitis was suspected. Imaging studies identified enhancing lesions in the thigh musculature, temporalis, parotid gland, pterygoid, masseter, tongue, cerebellum and leptomeninges. Biopsy of one of the thigh lesions confirmed the diagnosis of mucinous adenocarcinoma. She succumbed to the disease in November 2013. This case illustrates the aggressive nature of mucinous epithelial ovarian cancer and its resilience to conventional chemotherapy. On account of its high death rate, it is recommended that the epithelial-mesenchymal transition be researched and early therapy targeted at the k-ras oncogene initiated in spite of the tumour's lower initial staging.

By 2013, she experienced insidious, debilitating and diffuse musculoskeletal pain with trismus. Polymyositis or diffuse radiculitis was suspected. Imaging studies identified enhancing lesions in the thigh musculature, temporalis, parotid gland, pterygoid, masseter, tongue, cerebellum and leptomeninges. Biopsy of one of the thigh lesions confirmed the diagnosis of mucinous adenocarcinoma. She succumbed to the disease in November 2013. This case illustrates the aggressive nature of mucinous epithelial ovarian cancer and its resilience to conventional chemotherapy. On account of its high death rate, it is recommended that the epithelial–mesenchymal transition be researched and early therapy targeted at the k-ras oncogene initiated in spite of the tumour's lower initial staging.

    2015-08-01

    Resveratrol, a natural polyphenol found in grapes, berries, and medicinal plants, exhibits antioxidant and anti-inflammatory activities and has been proposed to be a longevity-prolonging agent. There is also growing evidence that resveratrol has cardioprotective properties and beneficial effects on both glucose and lipid metabolism. Recently, several studies have examined the use of resveratrol as a therapeutic agent to treat numerous pathological and metabolic disorders. Herein, we present insights into the mechanisms of action, biological effects, and current evidence of actions of resveratrol on the ovary. In vitro, resveratrol inhibits proliferation and androgen production by theca-interstitial cells. Resveratrol also exerts a cytostatic, but not cytotoxic, effect on granulosa cells, while decreasing aromatization and vascular endothelial growth factor expression. In vivo, resveratrol treatment reduced the size of adipocytes and improved estrus cyclicity in the previously acyclic rat model of polycystic ovary syndrome (PCOS). In addition, resveratrol increased the ovarian follicular reserve and prolonged the ovarian life span in rats. Taken together, resveratrol emerges as a potential therapeutic agent to treat conditions associated with androgen excess, such as PCOS. The efficacy of resveratrol in the treatment of gynecological conditions requires further investigation. PMID:26315293

    Primary ovarian insufficiency is a condition that represents impaired ovarian function on a continuum with intermittent ovulation. This condition commonly leads to premature menopause, defined as cessation of ovulation prior to the age of 40 years. Because there are potential immediate and long-term consequences of hypoestrogenism, a timely diagnosis is invaluable. This comprehensive review will discuss identifiable causes for primary ovarian insufficiency, including genetic disorders and metabolic abnormalities, as well as review current strategies for diagnosis, evaluation, and management of women with this condition.

    2014-01-01

    Understanding cancer cell signal transduction is a promising lead for uncovering therapeutic targets and building treatment-specific markers for epithelial ovarian cancer. To brodaly assay the many known transmembrane receptor systems, previous studies have employed gene expression data measured on high-throughput microarrays. Starting with the knowledge of validated ligand-receptor pairs (LRPs), these studies postulate that correlation of the two genes implies functional autocrine signaling. It is our goal to consider the additional weight of evidence that prognosis (progression-free survival) can bring to prioritize ovarian cancer specific signaling mechanism. We survey three large studies of epithelial ovarian cancers, with gene expression measurements and clinical information, by modeling survival times both categorically (long/short survival) and continuously. We use differential correlation and proportional hazards regression to identify sets of LRPs that are both prognostic and correlated. Of 475 candidate LRPs, 77 show reproducible evidence of correlation; 55 show differential correlation. Survival models identify 16 LRPs with reproduced, significant interactions. Only two pairs show both interactions and correlation (PDGFAPDGFRA and COL1A1CD44) suggesting that the majority of prognostically useful LRPs act without positive feedback. We further assess the connectivity of receptors using a Gaussian graphical model finding one large graph and a number of smaller disconnected networks. These LRPs can be organized into mutually exclusive signaling clusters suggesting different mechanisms apply to different patients. We conclude that a mix of autocrine and endocrine LRPs influence prognosis in ovarian cancer, there exists a heterogenous mix of signaling themes across patients, and we point to a number of novel applications of existing targeted therapies which may benefit ovarian cancer.

    Background Acrylamide is a probable human carcinogen formed during cooking of many common foods. Epidemiological studies of acrylamide and breast cancer risk have been null; however, positive associations with ovarian and endometrial cancers have been reported. We studied acrylamide intake and risk of breast, endometrial, and ovarian cancers in a prospective cohort study. Methods We assessed acrylamide intake among 88,672 women in the Nurses’ Health Study using food frequency questionnaires administered every four years. Between 1980 and 2006 we identified 6301 cases of invasive breast cancer, 484 cases of invasive endometrial adenocarcinoma, and 416 cases of epithelial ovarian cancer. We used Cox proportional hazards models to study the association between acrylamide and cancer risk. Results We found no association between acrylamide intake and breast cancer overall or according to estrogen and progesterone receptor status. We found an increased risk of endometrial cancer among high acrylamide consumers (adjusted relative risk [RR] for highest versus lowest quintile=1.41, 95% CI: 1.01–1.97, p-value for trend=0.03). We observed a non-significant suggestion of increased risk for ovarian cancer overall (RR 1.25, CI: 0.88–1.77, p-trend=0.12), with a significantly increased risk for serous tumors (RR 1.58, CI: 0.99–2.52, p-trend=0.04). Associations did not differ by smoking status. Conclusions We observed no association between acrylamide and breast cancer. Risk of endometrial cancer and possibly ovarian cancer was greater among high acrylamide consumers. Impact This is the second prospective study to report positive associations with endometrial and ovarian cancers. These associations should be further evaluated to inform public health policy.

    Background. Reproductive-aged women frequently receive both chemotherapy and endocrine therapy as part of their treatment regimen for early stage hormone receptor-positive breast cancer. Chemotherapy results in transient or permanent ovarian failure in the majority of women. The difficulty in determining which patients will recover ovarian function has implications for adjuvant endocrine therapy decision making. We hypothesized that pretreatment serum anti-Müllerian hormone (AMH) and inhibin B concentrations would predict for ovarian function following chemotherapy. Methods. Pre- and perimenopausal women aged 25–50 years with newly diagnosed breast cancer were enrolled. Subjects underwent phlebotomy for assessment of serum AMH, inhibin B, follicle-stimulating hormone, and estradiol prior to chemotherapy and 1 month and 1 year following completion of treatment. Associations among hormone concentrations, clinical factors, and biochemically assessed ovarian function were assessed. Results. Twenty-seven subjects were evaluable for the primary endpoint. Median age was 41. Twenty subjects (74.1%) experienced recovery of ovarian function within 18 months. Of the 26 evaluable subjects assessed prior to chemotherapy, 19 (73.1%) had detectable serum concentrations of AMH. The positive predictive value of a detectable baseline serum AMH concentration for recovery of ovarian function was 94.7%, and the negative predictive value was 85.7%. On univariate analysis, younger age and detectable serum AMH concentration at chemotherapy initiation were predictive of increased likelihood of recovery of ovarian function. Conclusion. Prechemotherapy assessment of serum AMH may be useful for predicting postchemotherapy ovarian function. This finding has implications for decision making about adjuvant endocrine therapy in premenopausal women treated with chemotherapy. PMID:24319018

  19. Copy neutral loss of heterozygosity is more frequent in older ovarian cancer patients

    2013-01-01

    Loss of heterozygosity (LOH) is a common type of genomic alterations in ovarian cancer. Analyzing 74,415 copy neutral LOH events in 513 serous ovarian adenocarcinomas samples from the Cancer Genome Atlas, we report that the frequency of LOH events increases with age. Similar trend is observed for chromosome 17, which is frequently implicated in ovarian cancer. The results are consistent when we analyze data from the Boston High-grade serous cancer (HGSC) cohort. We further show that germ line and somatic mutations in BRCA1 (in chromosome 17) and BRCA2 (in chromosome 13) loci are not necessary to establish the pattern. We also report significant age-related changes in expression patterns for several genes in the homologous recombination (HR) pathway such as BRCA1, RAD50, RAD52, XRCC2, XRCC3, and MRE11A in these patient samples. Furthermore, we develop a metric for pathway-level imbalance, and show that increased imbalance in the HR pathway i.e. increase in expression of some HR genes and decrease in expression of others - is common, and correlates significantly with the frequency of LOH events in the patient samples. Taken together, it is highly likely that aging and deregulation of HR pathway contribute to the increased incidence of copy-neutral loss of heterozygosity in ovarian cancer patients. PMID:23716468

    The present study screened potential genes related to lung adenocarcinoma, with the aim of further understanding disease pathogenesis. The GSE2514 dataset including 20 lung adenocarcinoma and 19 adjacent normal tissue samples from 10 patients with lung adenocarcinoma aged 45-73 years was downloaded from Gene Expression Omnibus. Differentially expressed genes (DEGs) between the two groups were screened using the t-test. Potential gene functions were predicted using functional and pathway enrichment analysis, and protein-protein interaction (PPI) networks obtained from the STRING database were constructed with Cytoscape. Module analysis of PPI networks was performed through MCODE in Cytoscape. In total, 535 upregulated and 465 downregulated DEGs were identified. These included ATP5D, UQCRC2, UQCR11 and genes encoding nicotinamide adenine dinucleotide (NADH), which are mainly associated with mitochondrial ATP synthesis coupled electron transport, and which were enriched in the oxidative phosphorylation pathway. Other DEGs were associated with DNA replication (PRIM1, MCM3, and RNASEH2A), cell surface receptor-linked signal transduction and the enzyme-linked receptor protein signaling pathway (MAPK1, STAT3, RAF1, and JAK1), and regulation of the cytoskeleton and phosphatidylinositol signaling system (PIP5K1B, PIP5K1C, and PIP4K2B). Our findings suggest that DEGs encoding subunits of NADH, PRIM1, MCM3, MAPK1, STAT3, RAF1, and JAK1 might be associated with the development of lung adenocarcinoma. PMID:26840709

    OBJECTIVE: This single-institution experience retrospectively reviews the outcomes in a group of patients treated 5 or more years ago by pancreaticoduodenectomy for periampullary adenocarcinoma. SUMMARY BACKGROUND DATA: Controversy exists regarding the benefit of resection for periampullary adenocarcinoma, particularly for pancreatic tumors. Many series report only Kaplan-Meier actuarial 5-year survival rates. There are believed to be discrepancies between the actuarial 5-year survival data and the actual 5-year survival rates. METHODS: From April 1970 through May 1992, 242 patients underwent pancreaticoduodenal resection for periampullary adenocarcinoma at The Johns Hopkins Hospital. Follow-up was complete through May 1997. All pathology specimens were reviewed and categorized. Actual 5-year survival rates were calculated. The demographic, intraoperative, pathologic, and postoperative features of patients surviving > or =5 years were compared with those of patients who survived <5 years. RESULTS: Of the 242 patients with resected periampullary adenocarcinoma, 149 (62%) were pancreatic primaries, 46 (19%) arose in the ampulla, 30 (12%) were distal bile duct cancers, and 17 (7%) were duodenal cancers. There was a 5.3% operative mortality rate during the 22 years of the review, with a 2% operative mortality rate in the last 100 patients. There were 58 5-year survivors, 28 7-year survivors, and 7 10-year survivors. The tumor-specific 5-year actual survival rates were pancreatic 15%, ampullary 39%, distal bile duct 27%, and duodenal 59%. When compared with patients who did not survive 5 years, the 5-year survivors had a significantly higher percentage of well-differentiated tumors (14% vs. 4%; p = 0.02) and higher incidences of negative resection margins (98% vs. 73%, p < 0.0001) and negative nodal status (62% vs. 31%, p < 0.0001). The tumor-specific 10-year actuarial survival rates were pancreatic 5%, ampullary 25%, distal bile duct 21%, and duodenal 59%. CONCLUSIONS

    Regenerating islet-deprived gene family, number 4 (REG4), is a novel marker for intestinal differentiation. We performed immunohistochemical studies on REG4, cytokeratin (CK)7, CK20, and caudal type homeobox 2 (CDX2) in 291 ovarian mucinous tumors. There were 226 primary tumors and 65 metastatic tumors. The primary tumors comprised 69/226 mucinous cystadenomas, 79/226 mucinous borderline tumors (64/79 intestinal-type and 15/79 endocervical-like tumors), and 78/226 mucinous carcinomas. We found that REG4 expression was significantly higher in mucinous borderline tumors (30/79, 38.0%) and primary mucinous carcinomas (26/78, 33.3%) than in mucinous cystadenomas (4/69, 5.8%; P<0.05). However, REG4 expression was more commonly associated with intestinal-type, borderline, mucinous tumors rather than the endocervical-like type (30/64 vs. 0/15, P<0.001). There was a significant correlation between the REG4 and CDX2 expression profiles in primary ovarian mucinous tumors (r=0.772, P<0.001). REG4, CDX2, and diffuse CK20 had higher expression frequencies in metastatic lower gastrointestinal adenocarcinoma than in primary mucinous tumors (P<0.01). The CK7/REG4 coordinate expression profile was comparable in diagnostic value to CK7/CK20 or CK7/CDX2 profile. We conclude that REG4 expression is common in mucinous borderline tumors of the intestinal type as it is absent in the endocervical-like form in this series. Expression of CK7/REG4 may contribute to the differential diagnosis between primary and metastatic ovarian mucinous tumors. PMID:23958547

    Objective: The aim of this study was to evaluate fertility-sparing therapy in young patients with endometrial carcinoma. Methodology: This prospective study was carried out on 8 patients with clinical and radio-graphic stage IA, well differentiated endometrioid adenocarcinoma of the endometrium in Alzahra hospital, Tabriz, Iran. Treatment comprised high-dose megestrol acetate. Dilatation and curettage was repeated every three months. Results: The mean age of the patients was 30 (SD,3.21) years (range 24-35). Of the 8 patients, 7 (87.5%) achieved complete response. The mean time to response was 6.5 months (range 3-9). Of the complete responders, 3 of 7(42.8%) had recurrence; one patient underwent immediate hysterectomy, and 2 were successfully treated with second-line therapy and both subsequently conceived. Conception occurred in 3 of 7 patients (42.8%), in two more than once, However successful pregnancy occurred only in two patients. One patient developed Concomitant ovarian adenocarcinoma. Conclusions: High dose progestin therapy can be an effective fertility-sparing treatment in young patients with well differentiated stage IA endometrial endometrioid cancer confined to endometrium. However, close follow up is required because of risks of conservative treatment. PMID:24353597

    Sclerosing stromal tumour (SST) of the ovary is an extremely rare and benign ovarian neoplasm, accounting for 6% of the sex cord stromal ovarian tumours subtype. Usually, it is found during the second and third decades of life. Patients commonly present with pelvic pain, a palpable pelvic mass or menstrual irregularity. We report a case of a 20-year-old woman reporting of mild pelvic pain, with normal laboratory data. On imaging examinations, a large right adnexal tumour was found, with features suggesting an ovarian sex cord tumour. The patient underwent right salpingo-oophorectomy, diagnosing a SST of the ovary. This paper also reviews the literature, and emphasises the typical pathological and imaging characteristics of these rare benign ovarian lesions, and their impact, in a conservative surgery.

    A few breakthroughs have been accomplished for the treatment of ovarian cancer, the most deadly gynecologic carcinoma, in the current era of targeted oncologic treatment. The estrogen receptor was the first target of such treatments with the introduction of tamoxifen four decades ago in breast cancer therapeutics. Attempts to duplicate the success of hormonal therapies in ovarian cancer met with mixed results, which may be due to an inferior degree of hormone dependency in this cancer. Alternatively, this may be due to the failure to clearly identify the subsets of ovarian cancer with hormone sensitivity. This article reviews the expression of hormone receptors by ovarian cancer cells, the prognostic value of these expressions, and their predictive capacity for response to hormonal agents. The possible ways ahead are briefly discussed. PMID:27053923

    Carbohydrate antigen 72-4 (CA72-4) is a human tumor-associated glycoprotein, commonly used as a tumor marker for diagnosing and predicting outcome in gastric and ovarian cancers. However, the relationship between serum CA72-4 levels and prognosis of pancreatic adenocarcinoma has not been fully elucidated. A total of 113 consecutive locally advanced pancreatic adenocarcinoma patients who underwent intensity-modulated radiation therapy (IMRT) with or without chemotherapy were enrolled in this study. Serum CA72-4 levels were analyzed using immunoenzymometric assays. The association between serum CA72-4 levels and prognosis was evaluated. Serum CA72-4 levels was related with lymph node metastasis (P<0.001). The median overall survival time was 14.0 months for patients with serum CA72-4 normal levels and 10.0 months for the elevated levels (P<0.001). Multivariate analysis identified that Serum CA72-4 concentration was a significant prognostic factor (P<0.001). The hazard ratio (HR) of elevated serum CA72-4 levels compared with normal serum CA72-4 levels was 2.34 (95% confidence interval [CI]: 1.46-3.73), after adjusted for gender and age. Based on this finding, Serum CA72-4 is a potential marker to predict lymph node metastasis and prognosis in pancreatic adenocarcinoma. PMID:25860937

    A new monoclonal antibody recognizing CEACAM6, which we named AP11, was generated by immunizing BALB/c mice with phytohemagglutinin-activated human peripheral blood mononuclear cells. This study aims to evaluate whether CEACAM6 can serve as a tumor marker using AP11. We examined the expression of CEACAM6 with AP11 in 11 human carcinoma cell lines by flow cytometry and 439 human tissues including 282 tumor tissues and 157 normal tissues by immunohistochemistry. CEACAM6 epitope recognized by AP11 was well preserved in formalin-fixed and paraffin-embedded tissues. Adenocarcinomas of the stomach (86%), colorectum (95%), pancreas (100%), and lung (83%), urinary bladder (100%), and mucinous ovarian tumors (88%) had a high rate of CEACAM6 immunoreactivity. We observed a variable expression of CEACAM6 in hepatocellular carcinomas (35%), squamous cell carcinomas of the lung (60%), renal cell carcinomas (14%), urothelial carcinomas (13%), serous carcinomas of the ovary (17%), and breast carcinomas (11%). Small-cell carcinomas of the lung, prostatic adenocarcinomas, papillary thyroid carcinomas, malignant melanomas, giant cell tumors, and osteosarcomas were negative for CEACAM6. All normal tissues of various organs were negative for CEACAM6. In conclusion, CEACAM6 as detected by AP11, may serve as a marker for mucin-producing adenocarcinomas of the gastrointestinal tract and ovary as well as non-small cell lung cancer. Thus, AP11 represents a valuable diagnostic tool for detecting CEACMA6-positive cancers. PMID:25427744

    A 11-year-old, spayed, female mixed breed-dog was presented with an abdominal mass that was detected 1 month ago. Upon abdominal palpation a large, firm, oval shaped, movable mass was found in the mid-abdominal region. Survey radiograph of the abdomen demonstrated an oval soft tissue dense mass located on the right side of the abdominal cavity. A large, heteregenous and cystic mass with solid components occupying the majority of the abdomen and a small, cystic mass with solid components caudal to the left kidney were identified by transabdominal ultrasonography. Computed tomography scans revealed bilateral ovarian masses, and a small volume of retroperitoneal fluid on the right side. A cystic, but otherwise solid mass located in the right ovary and small retained left ovary encapsulated in the ovarian bursa were excised surgically by midline laparotomy. Histopathological examination of the excised mass from the right side revealed a large cystic structure consistent with an ovarian cyst and multiple corpora lutea and follicles at different maturational stages were detected in the left ovary. The precise origin of the ovarian cyst could not be determined by morphological appearance. Immunohistochemical staining suggested a cyst of surface epithelial origin. At re-examination 6 months after the surgery, the bitch appeared healthy and the clinical findings were all normal. To our knowledge, the cyst described here is the largest reported in an incompletely ovariohysterectomized bitch. PMID:21535241

    Few cases of neuroendocrine carcinoma (NEC) of the gallbladder (GB-NEC) have been reported. Data obtained from the 10 patients with GB-NEC treated in our hospital between January 2008 and December 2012 were retrospectively analyzed and compared with those of 377 patients with gallbladder adenocarcinoma. GB-NEC accounted for 2.2% of all gallbladder cancers. The patients (8 females and 2 males) were 59.0 ± 10.0 years old. Four patients presented mixed adenocarcinoma, while six had pure NEC. Immunohistochemical examinations showed a positive rate of 100% for CgA, NSE, and CK; the positive rates for Syn, EMA, and CD56 were 88.9, 87.5, and 75%, respectively. TNM grades II, IVA, and IVB were found in 1, 2, and 7 patients, respectively. GB-NEC patients showed significantly higher N2 lymphatic metastasis rates than gallbladder adenocarcinoma patients (70.0 vs. 34.0%; P < 0.05). Two patients were treated with radical resection and the remaining 8 with palliative operation. The 1-, 2-, and 3-year survival rates were 20, 10, and 0%, respectively (median survival time, 3.0 m); the 1-, 2-, 3-, and 5-year survival rates for all gallbladder adenocarcinoma patients were 38.0, 31.0, 30.1, and 28.4%, respectively (median survival time, 6.0 m), the difference was statistically significant (P = 0.038). The results demonstrate that GB-NEC was mainly found in aged females and shows high malignancy. Its prognosis is poorer than that of gallbladder adenocarcinoma, and surgical resection combined with TACE, radiotherapy, and chemotherapy could increase patient survival. PMID:26339390

    Premature ovarian failure (POF) is clinically suspected by amenorrhea and confirmed by an elevated FSH serum level above 40 mUI/L (even 20 mUI/L) twice, in a woman before the age of 40. Prevalence of POF is between 1 to 2% in women. In 90% of cases, no aetiology is identified. Obvious causes are chemotherapy, pelvic radiotherapy, ovarian surgery and diethylstilbestrol exposure in utero. A karyotype should be performed as Turner Syndrome is the most frequent genetic cause of POF. Some X abnormalities such as X deletion or X autosome translocation can be found. FMR1 pre-mutation (fragile X syndrome) should be searched for, even though no cases of mental retardation are known, in the family. Other genetic abnormalities can be suggested by associated symptoms (i.e.: FOXL2, SF1 mutations). Auto-immune aetiology can be suspected if other auto-immune features are present, however, there are no reliable auto-antibodies to confirm auto-immunity in POF. Treatment of POF is based on hormonal replacement therapy in order to avoid estrogen deficiency, suppress vasomotor symptoms and avoid bone loss as well as cardiovascular risk. Estrogens should be associated with progesterone or a progestin, at least up to the age of 51. Patients with POF should be informed that spontaneous pregnancies may occur (in 5% of cases). In case of desire of pregnancy, the patient should be oriented to a specialized unit for in vitro fertilization with oocyte donation. Psychological support is essential and should be part of the treatment. POF is associated with an increased risk of emotional distress and depression. No preventive treatment of POF is available so far. PMID:24157186

    Introduction. The well-documented role of the PDGF system in tumor growth and angiogenesis has prompted the development of new biological agents targeting the PDGF system. The aim of the present study was to analyze the expression of the PDGF-receptors in ovarian cancer and to investigate its relation to histopathological parameters and long-term overall survival. Methods. The immunohistochemical expression of PDGFR-α and PDGFR-β was investigated in tumor and stromal cells in 170 patients with histologically verified epithelial ovarian cancer. Results. Almost half of the tumor specimens showed high expression of PDGFR-α and PDGFR-β in tumor cells (43% and 41%) and in stromal compartments (32% and 44%). There was a significant association between high expression of PDGFR-α and high expression of PDGFR-β in both tumor and stromal cells. Coexpression of PDGFR-α and PDGFR-β in stromal cells was seen more often in serous adenocarcinomas than in nonserous adenocarcinomas. No clear correlation between PDGFR expression and longterm overall survival or clinical parameters was found. Conclusions. PDGFR-α and PDGFR-β were expressed in a subset of ovarian carcinomas but did not show significant prognostic importance in this material. PMID:23094199

    Background Metastasis associated in lung adenocarcinoma transcript-1 (MALAT-1) is overexpressed during cancer progression and promotes cell migration and invasion in many solid tumors. However, its role in ovarian cancer remains poorly understood. Methods Expressions of MALAT-1 were detected in 37 normal ovarian tissues and 45 ovarian cancer tissues by reverse transcription polymerase chain reaction (RT-PCR). Cell proliferation was observed by CCK-8 assay; Flow cytometry was used to measure cell cycle and apoptosis; Cell migration was detected by transwell migration and invasion assay. In order to evaluate the function of MALAT-1, shRNA combined with DNA microarray and Functional enrichment analysis were performed to determine the transcriptional effects of MALAT-1 silencing in OVCAR3 cells. RNA and protein expression were measured by qRT-PCR and Western blotting, respectively. Results We found that upregulation of MALAT-1 mRNA in ovarian cancer tissues and enhanced MALAT-1 expression was associated with FIGO stage. Knockdown of MALAT-1 expression in OVCAR3 cells inhibited cell proliferation, migration, and invasion, leading to G0/G1 cell cycle arrest and apoptosis. Overexpressed MALAT-1 expression in SKOV3 cells promoted cell proliferation, migration and invasion. Downregulation of MALAT-1 resulted in significant change of gene expression (at least 2-fold) in 449 genes, which regulate proliferation, cell cycle, and adhesion. As a consequence of MALAT-1 knockdown, MMP13 protein expression decreased, while the expression of MMP19 and ADAMTS1 was increased. Conclusions The present study found that MALAT-1 is highly expressed in ovarian tumors. MALAT-1 promotes the growth and migration of ovarian cancer cells, suggesting that MALAT-1 may be an important contributor to ovarian cancer development. PMID:27227769

    Recent evidence suggests that ovarian high-grade serous carcinoma (HGSC) originates from the epithelium of the fallopian tube. However, most mouse models are based on the previous prevailing view that ovarian cancer develops from the transformation of the ovarian surface epithelium. Here, we report the extensive histological and molecular characterization of the mogp-TAg transgenic mouse, which expresses the SV40 large T-antigen (TAg) under the control of the mouse müllerian-specific Ovgp-1 promoter. Histological analysis of the fallopian tubes of mogp-TAg mice identified a variety of neoplastic lesions analogous to those described as precursors to ovarian HGSC. We identified areas of normal-appearing p53-positive epithelium that are similar to 'p53 signatures' in the human fallopian tube. More advanced proliferative lesions with nuclear atypia and epithelial stratification were also identified that were morphologically and immunohistochemically reminiscent of human serous tubal intraepithelial carcinoma (STIC), a potential precursor of ovarian HGSC. Beside these non-invasive precursor lesions, we also identified invasive adenocarcinoma in the ovaries of 56% of the mice. Microarray analysis revealed several genes differentially expressed between the fallopian tube of mogp-TAg and wild-type (WT) C57BL/6. One of these genes, Top2a, which encodes topoisomerase IIα, was shown by immunohistochemistry to be concurrently expressed with elevated p53 and was specifically elevated in mouse STICs but not in the surrounding tissues. TOP2A protein was also found elevated in human STICs, low-grade and high-grade serous carcinoma. The mouse model reported here displays a progression from normal tubal epithelium to invasive HGSC in the ovary, and therefore closely simulates the current emerging model of human ovarian HGSC pathogenesis. This mouse therefore has the potential to be a very useful new model for elucidating the mechanisms of serous ovarian tumourigenesis, as well as

    Adenocarcinoma is a type of cancer that occurs in the glandular cells throughout the body. There are several metastatic adenocarcinoma of unknown primary origin. Currently, there is no highly effective method to differentiate pancreatic ductal adenocarcinoma (PDAC) from other adenocarcinomas. Here, we identified pancreas tissue by site-specific methylation at FRY and found that it can also detect PDAC. The establishment of Combined Bisulphite Restriction Analysis (COBRA) and quantitative real-time PCR techniques of FRY revealed FRY hypermethylation in 21 out of 24 normal pancreatic tissue samples, whereas all other normal tissue samples from thirteen other organs (80 samples) remained totally unmethylated. Similarly in application to PDAC, this marker effectively indicated 25 PDAC among 151 other common adenocarcinomas with values of 100%, 98.7%, 92.6%, and 100% in sensitivity, specificity, positive predictive value and negative predictive value, respectively. In summary, we have demonstrated that this epigenetic site-specific marker has high potential for pancreatic tissue identification and can be applied in PDAC diagnosis. PMID:26990916

    Over the past several decades, adenocarcinoma of the lung has been increasing as a fraction of all lung cancer. Examination of the available evidence led the 2014 Report of the Surgeon General to conclude that the increases in the rates of adenocarcinoma among smokers in the U.S. were a result of changes in cigarette design and composition over the past 6 decades. While a causal link to design and composition changes as a whole is clear, the changes that have been implemented over the past several decades are not uniformly applied across all cigarette brands in the current market, raising questions about differences in risks among users of different cigarette brands. Recognition of the increased risks resulting from design and composition changes offers a corollary opportunity to reduce current disease risks by identifying and regulating the specific compositional and design changes that produced the increase in risk.

    Choroidal or cutaneous metastasis of gastric cancer is rare. Gastrointestinal cancer was found in only 4% in patients with uveal metastasis. Choroidal metastasis from gastric cancer was reported in two cases in earlier literature. The frequency of gastric cancer as a primary lesion was 6% in cutaneous metastasis of men, and cutaneous metastasis occurs in 0.8% of all gastric cancers. We report a patient with gastric adenocarcinoma who presented with visual disorder in his left eye and skin pain on his head as his initial symptoms. These symptoms were diagnosed to be caused by choroidal and cutaneous metastasis of gastric adenocarcinoma. Two cycles of chemotherapy consisted of oral S-1 and intravenous cisplatin (SPIRITS regimen); this was markedly effective to reduce the primary gastric lesion and almost all the metastatic lesions.

    Primary adenocarcinomas of the presacral (retrorectal) space are rare. The diagnosis is usually delayed because of non-specific symptoms, and is made after a biopsy or surgery. These carcinomas arise from cystic lesions developing from remnants of the embryological postanal gut containing mucous-secreting epithelium, known as tail gut cysts. The potential for infection, perianal fistulas and most importantly, malignant change warrants an early complete surgical resection. From an oncologist’s perspective, the management of these carcinomas has varied, and has included adjuvant chemotherapy and/or radiation therapy. We describe here a rare case of adenocarcinoma associated with a tail gut cyst that was discovered incidentally and resected by a posterior approach (Kraske procedure). The patient has had clinical and periodic radiologic surveillance without any evidence of cancer recurrence for over a year and a half. PMID:23450681

    The circadian clock controls metabolic and physiological processes through finely tuned molecular mechanisms. The clock is remarkably plastic and adapts to exogenous "zeitgebers," such as light and nutrition. How a pathological condition in a given tissue influences systemic circadian homeostasis in other tissues remains an unanswered question of conceptual and biomedical importance. Here, we show that lung adenocarcinoma operates as an endogenous reorganizer of circadian metabolism. High-throughput transcriptomics and metabolomics revealed unique signatures of transcripts and metabolites cycling exclusively in livers of tumor-bearing mice. Remarkably, lung cancer has no effect on the core clock but rather reprograms hepatic metabolism through altered pro-inflammatory response via the STAT3-Socs3 pathway. This results in disruption of AKT, AMPK, and SREBP signaling, leading to altered insulin, glucose, and lipid metabolism. Thus, lung adenocarcinoma functions as a potent endogenous circadian organizer (ECO), which rewires the pathophysiological dimension of a distal tissue such as the liver. PAPERCLIP. PMID:27153497

    Appendiceal adenocarcinoma typically presents as an incidentally noted appendiceal mass, or with symptoms of right lower quadrant pain that can mimic appendicitis, but local involvement of adjacent organs is uncommon, particularly as the presenting sign. We report on a case of a primary appendiceal cancer initially diagnosed as a rectal polyp based on its appearance in the rectal lumen. The management of the patient was in keeping with standard practice for a rectal polyp, and the diagnosis of appendiceal adenocarcinoma was made intraoperatively. The operative strategy had to be adjusted due to this unexpected finding. Although there are published cases of appendiceal adenocarcinoma inducing intussusception and thus mimicking a cecal polyp, there are no reports in the literature describing invasion of the appendix through the rectal wall and thus mimicking a rectal polyp. The patient is a 75-year-old female who presented with spontaneous hematochezia and, on colonoscopy, was noted to have a rectal polyp that appeared to be located within a diverticulum. When endoscopic mucosal resection was not successful, she was referred to colorectal surgery for a low anterior resection. Preoperative imaging was notable for an enlarged appendix adjacent to the rectum. Intraoperatively, the appendix was found to be densely adherent to the right lateral rectal wall. An en bloc resection of the distal sigmoid colon, proximal rectum and appendix was performed, with pathology demonstrating appendiceal adenocarcinoma that invaded through the rectal wall. The prognosis in this type of malignancy weighs heavily on whether or not perforation and spread throughout the peritoneal cavity have occurred. In this unusual presentation, an en bloc resection is required for a complete resection and to minimize the risk of peritoneal spread. Unusual appearing polyps do not always originate from the bowel wall. Abnormal radiographic findings adjacent to an area of gastrointestinal pathology may

    The prognosis of malignancies in young women undergoing chemotherapy has dramatically improved recently, and more attention is given to the long term quality of life, including fertility and reproductive function preservation. Some chemotherapeutic drugs are known to be associated with gonadal toxicity (cyclophosphamide, L-phenylanine mustard, busulfan and nitrogen mustard) and others have less or un-quantified effects (doxorubicin, bleomycin, vinca alkaloids, as vincristine and vinblastin, cisplatin, nitrosoureas, cytosine arabinoside). Women are in need to identify best options to minimize ovarian damage during chemotherapy through the administration of protective drugs, better choice of therapy and with advocating oncofertility preservation. We reviewed the possible options focusing on the most studied gonadotrophin-releasing hormone agonists (GnRH-a) and the psychologically promising oral contraceptives (OC). Controversy exist on the benefit of gonadotrophin releasing hormone agonist (GnRH-a) or combined oral contraceptive administered at time of cancer therapy in preventing premature ovarian failure in women and the available data from both human and animal studies have been mixed. The best way to preserve fertility and ovarian function in young women undergoing chemotherapy still remains to be determined. In the absence of a best approach, each case should be evaluated individually, considering patient's wishes and expectations, the type of chemotherapy, age, obstetric history, ovarian reserve (combining multiple indicators such as basal hormone profile, anti müllerian hormone -AMH- and antral follicle count), family history of premature ovarian failure. We present a review of the available evidence on the value of administering GnRH-a and OC use to minimize or prevent the effect of chemotherapy agents on reproductive function. PMID:24164203

    Pancreatic adenocarcinoma displays a variety of molecular changes that evolve exponentially with time and lead cancer cells not only to survive, but also to invade the surrounding tissues and metastasise to distant sites. These changes include: genetic alterations in oncogenes and cancer suppressor genes; changes in the cell cycle and pathways leading to apoptosis; and also changes in epithelial to mesenchymal transition. The most common alterations involve the epidermal growth factor receptor (EGFR) gene, the HER2 gene, and the K-ras gene. In particular, the loss of function of tumor-suppressor genes has been documented in this tumor, especially in CDKN2a, p53, DPC4 and BRCA2 genes. However, other molecular events involved in pancreatic adenocarcinoma pathogenesis contribute to its development and maintenance, specifically epigenetic events. In fact, key tumor suppressors that are well established to play a role in pancreatic adenocarcinoma may be altered through hypermethylation, and oncogenes can be upregulated secondary to permissive histone modifications. Indeed, factors involved in tumor invasiveness can be aberrantly expressed through dysregulated microRNAs. This review summarizes current knowledge of pancreatic carcinogenesis from its initiation within a normal cell until the time that it has disseminated to distant organs. In this scenario, highlighting these molecular alterations could provide new clinical tools for early diagnosis and new effective therapies for this malignancy. PMID:24084722

    Adenocarcinoma of the lung is the leading cause of cancer death worldwide. Here we report molecular profiling of 230 resected lung adenocarcinomas using messenger RNA, microRNA and DNA sequencing integrated with copy number, methylation and proteomic analyses. High rates of somatic mutation were seen (mean 8.9 mutations per megabase). Eighteen genes were statistically significantly mutated, including RIT1 activating mutations and newly described loss-of-function MGA mutations which are mutually exclusive with focal MYC amplification. EGFR mutations were more frequent in female patients, whereas mutations in RBM10 were more common in males. Aberrations in NF1, MET, ERBB2 and RIT1 occurred in 13% of cases and were enriched in samples otherwise lacking an activated oncogene, suggesting a driver role for these events in certain tumours. DNA and mRNA sequence from the same tumour highlighted splicing alterations driven by somatic genomic changes, including exon 14 skipping in MET mRNA in 4% of cases. MAPK and PI(3)K pathway activity, when measured at the protein level, was explained by known mutations in only a fraction of cases, suggesting additional, unexplained mechanisms of pathway activation. These data establish a foundation for classification and further investigations of lung adenocarcinoma molecular pathogenesis. PMID:25079552

    Objectives To identify factors associated with disease-specific survival (DSS) in intestinal and nonintestinal sinonasal adenocarcinoma. Design Retrospective review. Setting Surveillance Epidemiology and End Results database. Participants Adult patients with sinonasal adenocarcinoma. Main Outcome Measures DSS. Results We identified 325 patients; of these, 300 had the nonintestinal type and 25 had intestinal type histologies. The 5-year DSS rates for patients who had no treatment, radiation (RT), surgery, and surgery and postoperative RT were 42.5, 46.1, 85.6, and 72.6%, respectively (log-rank test; p < 0.001). Black race, age ≥ 75 years, paranasal sinus involvement, and high grade were independently associated with decreased DSS. Compared with RT, surgery (hazard ratio [HR]: 0.34; 95% confidence interval [CI]: 0.15-0.77), and adjuvant RT (HR: 0.47; 95% CI, 0.26-0.86) were associated with improved DSS. Conclusions There is no difference in prognosis between intestinal and nonintestinal subtypes of sinonasal adenocarcinoma. Treatment with surgery alone or adjuvant RT is associated with a more favorable prognosis. PMID:26225303

    This case presentation examines a rare clinical entity: colorectal adenocarcinoma (CRC) metastasis to the tongue. CRC is among the least common tumors to metastasize to the oral cavity. Objectives for this case report are to (1) maintain a high index of suspicion for oral cavity tumors representing metastatic disease, (2) consider appropriate surgical and adjunctive interventions, and (3) recognize the significance of identifying the primary tumor via immunohistochemical staining. We present a case of a 57-year-old male with a history of stage IV rectal adenocarcinoma metastatic to the lung who presented to our clinic with a painful mass of the right lateral tongue that he noticed one month before. MRI of the neck revealed a mass involving the anterior two-thirds of the right tongue with irregular margins and an ipsilateral enlarged right jugulodigastric lymph node. The patient underwent right partial glossectomy with primary reconstruction and right modified radical neck dissection. Pathology confirmed poorly differentiated adenocarcinoma consistent with a colorectal primary with lymphovascular and perineural invasion. The tumor was staged as T2N1, and the patient was referred for chemoradiation. In this report, we discuss the presentation, diagnosis, and treatment of this uncommon disease, with a thorough review of the world literature. PMID:26759728

    Esophageal adenocarcinoma (EAC) is one of the fastest growing malignancies in the US and needs newer therapeutic and diagnostic strategies. Chronic inflammation plays a role in the pathogenesis of EAC and contributes to the dysplastic conversion of normal esophageal epithelium to Barrett's esophagus and frank adenocarcinoma. Chemokines play important roles in mediating inflammation and recent evidence implicates these ligands and their receptors in the development and spread of various tumors. We demonstrated that the chemokines IL8, CXCL1 and CXCL3 are significantly overexpressed during esophageal carcinogenesis and accompanied by amplification and demethylation of the chr4q21 gene locus. We also demonstrated that IL8 levels can be detected in serum of patients with EAC and can serve as potential biomarkers. We now demonstrate that inhibition of IL8 receptor, CXCR2, leads to decreased invasiveness of esophageal adenocarcinoma derived cells without affecting cellular proliferation. Taken together, these studies reveal the important roles that chemokines play in development of esophageal cancer and demonstrate that these pathways can serve as potential therapeutic targets.

    Background Development of tailored treatment based on immunohistochemical profiles (IPs) of tumors for cancers of unknown primary is needed. Methodology/Principal Findings We developed an algorithm based on primary known adenocarcinoma for testing sensitivity and specificity. Formalin-fixed paraffin-embedded tissue samples from 71 patients of unfavorable subsets of unknown primary adenocarcinoma were obtained. We examined 15 molecular markers using the algorithm incorporating these IPs and classified the tumours into 9 subsets based on the primary tumour site. The sensitivity and specificity of this algorithm were 80.3% and 97.6%, respectively. Apparent primary sites were lung in 17 patients, digestive organs in 13, gynecological organs in 9, prostate in 7, liver or kidney in 6, breast in 4, urothelial organ in 2, biliary tract and pancreatic profile in none, and unclassified in 13. The response rate to chemotherapy was highest for the gynecological IPs. Patients with gynecological or lung cancer IPs had longer median progression-free survival than those with others: 11.2 months for gynecological IPs (p<0.001) and 6.8 months for lung IPs (p = 0.05). Lung, digestive, prostate, and gynecological profiles were associated with significantly longer median survival time than the other profiles. Multivariate analysis confirmed that the IPs were independent prognostic factors for survival. Conclusions/Significance The IPs identified in this study can be used to further stratify patient prognosis for unfavorable subsets of unknown primary adenocarcinoma. PMID:22299055

    Endometrial adenocarcinoma is a common malignancy in women worldwide, with formation of remote metastasis occurring following oncological treatment. Circulating tumor cells (CTCs) are regarded to be the origin of haematogenous metastasis formation. The present study aimed to identify suitable marker genes using a quantitative polymerase chain reaction (qPCR) approach to detect CTCs from blood samples of patients with endometrial carcinoma. Therefore, RNA was isolated from endometrial adenocarcinoma cell lines and from healthy endometrial tissue and reverse transcribed to cDNA, which was then used in qPCR on a number of marker genes. Cytokeratin 19 and claudin 4 were identified as suitable marker genes for CTCs in endometrial adenocarcinoma, due to their high expression in the majority of the cell lines investigated. The expression values of the genes examined varied widely between the different cell lines, which is similar to the variation in the patient samples. Therefore, the necessity for a set of genes for CTC detection and not one single marker gene is demonstrated. qPCR is a fast, cost‑efficient and easy to perform technique, which may be used in the detection of CTCs. Investigation of the occurrence of CTCs in cancer patients would aid in the prevention of metastasis and thereby refine treatment. PMID:27431566

    Ductal pancreatic adenocarcinoma is by far the most common solid tumor of the pancreas. It has a very poor prognosis, especially in the more advanced stages which are no longer locally confined. Due to mostly unspecific symptoms, imaging is key in the diagnostic process. Because of the widespread use of imaging techniques, incidental findings are to a greater extent discovered in the pancreas, which subsequently entail further work-up. Ductal pancreatic adenocarcinoma can be mimicked by a large number of different lesions, such as anatomical variants, peripancreatic structures and tumors, rarer primary solid pancreatic tumors, cystic tumors, metastases or different variants of pancreatitis. Additionally, a number of precursor lesions can be differentiated. The correct classification is thus important as an early diagnosis of ductal pancreatic adenocarcinoma is relevant for the prognosis and because the possibly avoidable treatment is very invasive. All major imaging techniques are principally suitable for pancreatic imaging. In addition to sonography of the abdomen, usually the baseline diagnostic tool, computed tomography (CT) with its superior spatial resolution, magnetic resonance imaging (MRI) with its good soft tissue differentiation capabilities, possibly in combination with MR cholangiopancreatography (MRCP), endosonography with its extraordinary spatial resolution, conceivably with additional endoscopic retrograde CP or the option of direct biopsy and finally positron emission tomography CT (PET-CT) as a molecular imaging tool are all particularly useful modalities. The various techniques all have its advantages and disadvantages; depending on the individual situation they may need to be combined. PMID:27000276

    Background Sinonasal adenocarcinomas are uncommon tumors which develop in the ethmoid sinus after exposure to wood dust. Although the etiology of these tumors is well defined, very little is known about their molecular basis and no diagnostic tool exists for their early detection in high-risk workers. Methods To identify genes involved in this disease, we performed gene expression profiling using cancer-dedicated microarrays, on nine matched samples of sinonasal adenocarcinomas and non-tumor sinusal tissue. Microarray results were validated by quantitative RT-PCR and immunohistochemistry on two additional sets of tumors. Results Among the genes with significant differential expression we selected LGALS4, ACS5, CLU, SRI and CCT5 for further exploration. The overexpression of LGALS4, ACS5, SRI, CCT5 and the downregulation of CLU were confirmed by quantitative RT-PCR. Immunohistochemistry was performed for LGALS4 (Galectin 4), ACS5 (Acyl-CoA synthetase) and CLU (Clusterin) proteins: LGALS4 was highly up-regulated, particularly in the most differentiated tumors, while CLU was lost in all tumors. The expression of ACS5, was more heterogeneous and no correlation was observed with the tumor type. Conclusion Within our microarray study in sinonasal adenocarcinoma we identified two proteins, LGALS4 and CLU, that were significantly differentially expressed in tumors compared to normal tissue. A further evaluation on a new set of tissues, including precancerous stages and low grade tumors, is necessary to evaluate the possibility of using them as diagnostic markers. PMID:19903339

    Ovaries are the female organs that age more quickly than other tissues such as the uterus, the pituitary gland or pancreas. Different from males, an interesting question is why and how the females lose fertility so rapidly. During the aging process, both the number and quality of the oocytes in the ovaries decrease and reach to a point beyond that no more viable offspring may be produced and the associated cyclic endocrinological activities cease, entering the menopause in females at an average age of 50 years. Females who delayed childbearing with or without their willing until their 30 years or 40 years constitute the largest portion of the total infertility population. Ovarian reserve tests (ORTs) provide an indirect estimate of a female’s diminishing ovarian reserve or remaining follicular pool. This article briefly reviews recent progresses in relation to ovarian aging and ORTs. PMID:26985328

    Metastasis of gastroesphageal junction (GEJ) adenocarcinoma in skeletal muscle is rare and primary sites for skeletal muscle metastases are usually lung, renal and colorectal cancer. We have encountered with the first case report of solitary psoas muscle metastasis of GEJ adenocarcinoma. Here we describe a 65 years old man was diagnosed with GEJ adenocarcinoma in Gastroenterology Department, Imam Hussein Hospital, Tehran, Iran in February 2014. We were not able to use PET techniques due to lack of access. Staging CT scans demonstrated a small mass lateral to right psoas muscle. A CT-guided core needle biopsy of right psoas muscle was performed that supported a diagnosis of adenocarcinoma consistent with primary adenocarcinoma of the GEJ. Distant metastasis to skeletal muscle rarely occurs in patients with GEJ adenocarcinoma, but heightened awareness to these soft tissue lesions is warranted. CT or MR imaging could show findings suggestive of metastatic disease, although PET is preferable modality. PMID:26870148

    Urothelial cancer is the most frequently diagnosed type of malignant tumor in the bladder, of which primary adenocarcinoma accounts for a small percentage. Secondary malignancies, in particular metastatic adenocarcinoma from the lung, are exceedingly rare, with only six cases previously reported in the literature. The present study describes the case of a 71-year-old Chinese male patient with known lung cancer for >2 years, who was diagnosed with metastatic adenocarcinoma to the bladder. The histopathological characteristics and immunohistochemical features of the patient are reported. It was proposed that pathologists should consider the possibility of metastatic adenocarcinoma from the lung, rather than assume a diagnosis of primary adenocarcinoma of the bladder or direct invasion of adenocarcinoma from the surrounding organs. Furthermore, it is essential to determine the medical history of each patient and observe the immunohistochemical features of all tumors prior to diagnosis. PMID:26622730

    Features of ultrasound picture of morphologically verified recurrence of ovarian cancer in 21 patients are presented, who received combined treatment including cytoreductive surgery in the form of hysterectomy with oophorectomy, resection of the greater omentum and 6 courses of chemotherapy CAP for ovarian cancer stage III (FIGO). In all patients cytoreductive surgery was optimal--without residual tumor. Recurrence of the disease was detected in 12-48 months in 80.9% of the cases. Three variants of recurrence was revealed by ultrasonography: isolated peritoneal dissemination, in 14.2% of the cases, which was mainly detected during the first 12 months; single entities in the projection of the small pelvis (61.9%) and mixed form (local lesions of small pelvis and peritoneal dissemination) in 23.8% of the cases.

    Although Crohn's disease has been associated with an increased risk of small bowel adenocarcinoma, primary adenocarcinoma arising from an ileostomy is a complication that has been rarely documented in Crohn's disease. Chronic small bowel inflammation may lead to development of malignancy through the dysplasia-carcinoma sequence. We report a case of a 61-year-old woman with Crohn's ileocolitis diagnosed with a primary adenocarcinoma at the ileostomy with metastases to the liver 47 years after proctocolectomy, and review the literature.

    Objective To compare the long term impact on ovarian reserve between laparoscopic ovarian cystectomy with bipolar electrocoagulation and laparotomic cystectomy with suturing for ovarian endometrotic cyst. Patient and method(s) 121 patients with benign ovarian endometroitic cysts were randomised to either laparoscopic ovarian cystectomy using bipolar electrocoagulation (61 patients) or laparotomic ovarian cystectomy using sutures (60 patients). Serum follicle-stimulating hormone, Antimullerian hormon, Basal antral follicle Count, mean ovarian diameter, and ovarian stromal blood flow velocity were measured at 6, 12 and 18 months after surgery and compared in both groups. Result(s) A statistically significant increase of serum FSH was found in the laproscopic bipolar group at 6-, 12 and 18-month postoperativly compared to open laparotomy suture group. Also, a statistically significant decrease of the mean AMH value occurred in laproscopic bipolar group at 6-, 12 and 18-month follow- up compared to open laparotomy suture group. Basal antral follicle number, mean ovarian diameter and peak systolic velocity were significantly decreased during the 6-, 12,18 -month follow-up in laproscopic bipolar group compared to open laparotomy suture group. Conclusion(s) After laproscopic ovarian cystecomy for endometrioma all pareameter of ovarian reseve are significantly decreased on long term follow up as compared to open laprotomy. PMID:24180348

    Ovarian cancer has a high mortality and novel-targeted treatment strategies have not resulted in breakthroughs for this disease. Insight into the molecular characteristics of ovarian tumors may improve diagnosis and selection of patients for treatment with targeted therapies. A potential way to achieve this is by means of molecular imaging. Generic tumor processes, such as glucose metabolism ((18)F-fluorodeoxyglucose) and DNA synthesis ((18)F-fluorodeoxythymidine), can be visualized non-invasively. More specific targets, such as hormone receptors, growth factor receptors, growth factors and targets of immunotherapy, can also be visualized. Molecular imaging can capture data on intra-patient tumor heterogeneity and is of potential value for individualized, target-guided treatment selection. Early changes in molecular characteristics during therapy may serve as early predictors of response. In this review, we describe the current knowledge on molecular imaging in the diagnosis and as an upfront or early predictive biomarker in patients with ovarian cancer. PMID:27141066

    Ovarian carcinoma is the most severe gynecological cancer with an overall incidence of 12 per 1000 Americans or Europeans developing it over 40 years of age. Only 3 of the 12 cases will receive efficient care because the diagnosis will be made too late. This study reveals the principal risk factors i.e. upper socioeconomic echelon, ovarian function uninterrupted by a pregnancy or usage of oral contraceptives, anamnestic evidence of ovarian carcinoma in the family, some hereditary disorders, external insults (talcum powder). The synthesis of these various risk factors permits a comprehensive review of the hypotheses of pathogenesis concerning recurrence of tumors. But corollary epidemiologic studies are still needed to try to define better the high risk groups whose follow-up systematic detection and testing is a priority. PMID:4023542

    Ovarian cancer is a complex and deadly disease that remains difficult to detect at an early curable stage. Furthermore, although some oncogenic (Kras, Pten/PI3K and Trp53) pathways that are frequently mutated, deleted or amplified in ovarian cancer are known, how these pathways initiate and drive specific morphological phenotypes and tumor outcomes remain unclear. We recently generated Pten fl/fl; KrasG12D;Amhr2-Cre mice to disrupt the Pten gene and express a stable mutant form of KrasG12D in ovarian surface epithelial (OSE) cells. Based on histopathologic criteria, the mutant mice developed low-grade ovarian serous papillary adenocarcinomas at an early age and with 100% penetrance. This highly reproducible phenotype provides the first mouse model in which to study this ovarian cancer subtype. OSE cells isolated from ovaries of mutant mice at 5 and 10 weeks of age exhibit temporal changes in the expression of specific Mullerian epithelial marker genes, grow in soft agar and develop ectopic invasive tumors in recipient mice, indicating that the cells are transformed. Gene profiling identified specific mRNAs and microRNAs differentially expressed in purified OSE cells derived from tumors of the mutant mice compared to WT OSE cells. Mapping of transcripts or genes between the mouse OSE mutant datasets, the Kras signature from human cancer cell lines and the human ovarian tumor array datasets, documented significant overlap, indicating that KRAS is a key driver of OSE transformation in this context. Two key hallmarks of the mutant OSE cells in these mice are the elevated expression of the tumor suppressorsTrp53 (p53) and its microRNA target, miR-34a-c. We propose that elevated TRP53 and miR-34a-c may exert negatively regulatory effects that reduce the proliferative potential of OSE cells leading to the low-grade serous adenocarcinoma phenotype.

    Ovarian cancer has the highest mortality of all gynecologic cancers with a five-year survival rate of only 30%. Because current imaging techniques (ultrasound, CT, MRI, PET) are not capable of detecting ovarian cancer early, most diagnoses occur in later stages (III/IV). Thus many women are not correctly diagnosed until the cancer becomes widely metastatic. On the other hand, while the majority of women with a detectable ultrasound abnormality do not harbor a cancer, they all undergo unnecessary oophorectomy. Hence, new imaging techniques that can provide functional and molecular contrasts are needed for improving the specificity of ovarian cancer detection and characterization. One such technique is photoacoustic imaging, which has great potential to reveal early tumor angiogenesis through intrinsic optical absorption contrast from hemoglobin or extrinsic contrast from conjugated agents binding to appropriate molecular receptors. To better understand the cancer disease process of ovarian tissue using photoacoustic imaging, it is necessary to first characterize the properties of normal ovarian tissue. We have imaged ex-vivo ovarian tissue using a 3D co-registered ultrasound and photoacoustic imaging system. The system is capable of volumetric imaging by means of electronic focusing. Detecting and visualizing small features from multiple viewing angles is possible without the need for any mechanical movement. The results show strong optical absorption from vasculature, especially highly vascularized corpora lutea, and low absorption from follicles. We will present correlation of photoacoustic images from animals with histology. Potential application of this technology would be the noninvasive imaging of the ovaries for screening or diagnostic purposes.

    There are limited data about the cutaneous metastases of gynecological malignancies in the literature. Based on this limited number of studies, cutaneous metastases from gynecological malignancies are uncommon occurrences. Cutaneous metastases from the synchronous endometrioid carcinoma of the uterine corpus and bilateral ovaries arising from endometriosis are extremely rare. Herein, we report a 51-year-old woman with FIGO Stage 1A Grade 1 endometrial endometrioid-type adenocarcinoma and synchronous bilateral Stage 1B ovarian endometrioid-type adenocarcinoma who presented 34 months following total abdominal hysterectomy and bilateral salpingo-oophorectomy with skin metastases. After the patient underwent an excisional biopsy, we applied a palliative radiotherapy. The patient received the combination therapy with cisplatin and doxorubicin after the completion of radiotherapy but the disease evolution was rapidly fatal and the patient died 4 months after her admission to our department due to widely disseminated disease.

    The patients referred for fertility preservation owing to a malignant disease do not represent the typical population of subfertile patients treated in IVF units. Cancer may affect multiple tissues throughout the body and can result in a variety of complications during controlled ovarian stimulation. Determination of the controlled ovarian stimulation protocol and gonadotropin dose for oocyte/embryo cryopreservation requires an individualized assessment. This review highlights the new protocols that are emerging to reduce time constraints and emphasizes management considerations to decrease complications. PMID:23635348

    A cellular model (SCCOHT-1) of the aggressive small cell hypercalcemic ovarian carcinoma demonstrated constitutive chemokine and growth factor production including HGF. A simultaneous presence of c-Met in 41% SCCOHT-1 cells suggested an autocrine growth mechanism. Expression of c-Met was also observed at low levels in the corresponding BIN-67 cell line (6.5%) and at high levels in ovarian adenocarcinoma cells (NIH:OVCAR-3 (84.4%) and SK-OV-3 (99.3%)). Immunohistochemistry of c-Met expression in SCCOHT tumors revealed a heterogeneous distribution between undetectable levels and 80%. Further characterization of SCCOHT-1 and BIN-67 cells by cell surface markers including CD90 and EpCAM demonstrated similar patterns with differences to the ovarian adenocarcinoma cells. HGF stimulation of SCCOHT-1 cells was associated with c-Met phosphorylation at Tyr1349 and downstream Thr202/Tyr204 phosphorylation of p44/42 MAP kinase. This HGF-induced signaling cascade was abolished by the c-Met inhibitor foretinib. Cell cycle analysis after foretinib treatment demonstrated enhanced G2 accumulation and increasing apoptosis within 72 h. Moreover, the IC50 of foretinib revealed 12.4 nM in SCCOHT-1 cells compared to 411 nM and 481 nM in NIH:OVCAR-3 and SK-OV-3 cells, respectively, suggesting potential therapeutic effects. Indeed, SCCOHT-1 and BIN-67 tumor xenografts in NODscid mice exhibited an approximately 10-fold and 5-fold reduced tumor size following systemic application of foretinib, respectively. Furthermore, foretinib-treated tumors revealed a significantly reduced vascularization and little if any c-Met-mediated signal transduction. Similar findings of reduced proliferative capacity and declined tumor size were observed after siRNA-mediated c-Met knock-down in SCCOHT-1 cells demonstrating that in vivo inhibition of these pathways contributed to an attenuation of SCCOHT tumor growth.

    Ovarian primary mucinous adenocarcinomas (MACs) are refractory to conventional therapy. Biomarkers for ovarian MAC could facilitate prognosis and targeted therapy, but are not currently available. The expression of human epidermal growth factor 2 (HER-2) has been linked to enhanced survival of MAC patients and may hold potential as a biomarker, but this potential has not been sufficiently investigated. In this study, we examined the clinicopathological features of 46 cases of MAC and 36 cases of patients with mucinous borderline tumors (MBTs). The expression of estrogen receptors (ER), progesterone receptors (PR), and HER2 were measured by immunohistochemistry and fluorescent in situ hybridization (FISH). Next, we compared the clinicopathological characteristics according to the HER2 expression profile. MBTs of the endocervical type tended to have simultaneous ER and PR expression (P = 0.0028) while MACs rarely showed ER or PR expression. HER2 expression was observed in 14 out of the 46 MACs (37.84%) and in none of the MBTs (P = 0.0002). HER2-positive MACs occurred approximately 10 years earlier than HER2-negative MACs (35.21 ± 4.768 years compared to 46.78 ± 1.977 years; P = 0.0105). All HER2-positive MACs demonstrated an expansile invasive pattern, while all MACs with infiltrative invasion pattern were HER2-negative (P = 0.0406). Kaplan-Meier survival analysis demonstrated a tendency for improved overall survival in HER2-positive MACs compared to HER2-negative MACs (P = 0.0389). In conclusion, HER2 overexpression in ovarian MACs is associated with an expansile, but not an infiltrative, invasion pattern and a favorable prognosis. Therefore, we suggest that HER2 may be a practical marker for histopathological categorization and a prognostic marker in ovarian MACs. PMID:25120802

    Alpha-fetoprotein-producing carcinoma (AFPC)/hepatoid adenocarcinoma (HAC) and neuroendocrine carcinoma (NEC) are uncommon in the stomach. Composite tumors consisting of these carcinomas and their histologic phenotypes are not well known. Between 2002 and 2007, to estimate the prevalence of composite tumors consisting of tubular adenocarcinoma, AFPC/HAC and NEC, we reviewed specimens obtained from 294 consecutive patients treated surgically for gastric cancer. We examined histological phenotype of tumors of AFPC or NEC containing the composite tumor by evaluating immunohistochemical expressions of MUC2, MUC5AC, MUC6, CDX2, and SOX2. Immunohistochemically, AFPC/HAC dominantly showed the intestinal or mixed phenotype, and NEC frequently showed the gastric phenotype. In the composite tumor, the tubular and hepatoid components showed the gastric phenotype, and the neuroendocrine component showed the mixed type. The unique composite tumor predominantly showed the gastric phenotype, and the hepatoid and neuroendocrine components were considered to be differentiated from the tubular component. PMID:22482081

    Recently, a novel fusion gene resulting from a linkage between the kinesin family member 5B gene (KIF5B; 10p11.22) and the rearranged during transfection gene (RET; 10q11.21) was identified in non-small cell lung cancer (NSCLC). However, the correlation between the KIF5B/RET fusion gene status and the clinicopathological features of surgically-treated lung cancer has not been well characterized. In this study, we have independently investigated the KIF5B/RET fusion gene status in 371 surgically-treated NSCLCs (270 were adenocarcinomas and 101 were squamous cell carcinomas), 60 breast cancers, 11 metastatic lung cancers from colon cancers and thyroid papillary adenocarcinoma cases at the Nagoya City University Hospital. The fusion gene status was analyzed by an RT-PCR-based assay and by using direct sequencing. We detected 3 of 270 cases of KIF5B/RET fusion genes in adenocarcinomas (1.1%) consisting of female and never smokers with mixed subtype adenocarcinomas. The fusion genes were detected exclusively with other mutations, such as EGFR, Kras, Braf, erbB2 mutations, and EML4/ALK fusion. KIF5B/RET fusion was not detected in the cases with squamous cell carcinoma or other types of cancers. From the 3 cases, 2 were KIF5B (exon 15); RET (exon 12) fusions with papillary dominant and 1 case was KIF5B (exon 22); RET (exon 12) fusion with solid dominant adenocarcinoma. The matched normal lung tissues did not display translocation. We reported KIF5B/RET fusion genes as a driver somatic mutation of lung adenocarcinomas. The cinicopathological backgrounds of the KIF5B/RET fusion-positive patients were similar with those of the EML4/ALK fusion-positive patients. The chimeric oncogene may be a promising molecular target for the personalized diagnosis and treatment of NSCLC. PMID:22797671

  18. Defining ovarian reserve to better understand ovarian aging

    PubMed Central

    2011-01-01

    Though a widely utilized term and clinical concept, ovarian reserve (OR) has been only inadequately defined. Based on Medline and PubMed searches we here define OR in its various components, review genetic control of OR, with special emphasis on the FMR1 gene, and discuss whether diminished OR (DOR) is treatable. What is generally referred to as OR reflects only a small portion of total OR (TOR), a pool of growing (recruited) follicles (GFs) at different stages of maturation. Functional OR (FOR) depends on size of the follicle pool at menarche and the follicle recruitment rate. Both vary between individuals and, at least partially, are under genetic control. The FMR1 gene plays a role in defining FOR at all ages. Infertility treatments have in the past almost exclusively only centered on the last two weeks of folliculogenesis, the gonadotropin-sensitive phase. Expansions of treatments into earlier stages of maturation will offer opportunity to significantly improve ovarian stimulation protocols, especially in women with DOR. Dehydroepiandrosterone (DHEA) may represent a first such intervention. Data generated in DHEA-supplemented women, indeed, suggest a new ovarian aging concept, based on aging of ovarian environments and not, as currently is believed, aging oocytes. PMID:21299886

    Polycystic ovarian disease (PCOD) was first described as a single disease by Stein and Leventhal in 1935, but now has been separated into several distinct entities, comprising a symptom complex. The most frequent presenting symptoms associated with PCOD are obesity, hirsutism, amenorrhea or anovulation, dysfunctional uterine bleeding, irregular menses, and infertility. The common finding of hirsutism in PCOD patients is a reflection of the hyperandrogenism resulting from elevation of all the androgens, including testosterone, androstenediol, dehydroepiandrostrone sulfate (DHEA-S), and androstenedione. Some patients with all the clinical features of PCOD can be shown, through appropriate testing, to have an attenuated form of classic congenital adrenal hyperplasia (CAH). Serum follicle stimulating hormone (FSH) levels are usually low or in the normal range, and serum luteinizing hormone (LH) levels are usually elevated in patients with PCOD, resulting in an altered LH/FSH ratio. Treatment for PCOD must be based on the needs and desires of the individual patient, and on the pathophysiology of the patient's particular abnormalities. When pregnancy is desired, ovulation induction with clomiphene is indicated. Clomiphene is a weak estrogen that induces a transient rise in serum LH and FSH, followed by a gonadotropic pattern similar to normal cycles. A 72% ovulation rate and a 41.8% conception rate have been reported after treatment with clomiphene. In patients who do not respond to clomiphene, or clomiphene with added human chorionic gonadotropin (hCG), human menopausal gonadotropin (hMG) can be used to induce ovulation, but the patient should be closely monitored for multiple ovulation, multiple pregnancy, or hyperstimulation syndrome. For patients not interested in conception, regular menstrual cyclicity can be restored and hyperandrogenism reduced with oral contraceptives (OCs). PMID:6232474

    Epithelial-to-mesenchymal transition (EMT) is a key process associated with tumor progression and metastasis. To define molecular features associated with EMT states, we undertook an integrative approach combining mRNA, miRNA, DNA methylation, and proteomic profiles of 38 cell populations representative of the genomic heterogeneity in lung adenocarcinoma. The resulting data were integrated with functional profiles consisting of cell invasiveness, adhesion, and motility. A subset of cell lines that were readily defined as epithelial or mesenchymal based on their morphology and E-cadherin and vimentin expression elicited distinctive molecular signatures. Other cell populations displayed intermediate/hybrid states of EMT, with mixed epithelial and mesenchymal characteristics. A dominant proteomic feature of aggressive hybrid cell lines was upregulation of cytoskeletal and actin-binding proteins, a signature shared with mesenchymal cell lines. Cytoskeletal reorganization preceded loss of E-cadherin in epithelial cells in which EMT was induced by TGFβ. A set of transcripts corresponding to the mesenchymal protein signature enriched in cytoskeletal proteins was found to be predictive of survival in independent datasets of lung adenocarcinomas. Our findings point to an association between cytoskeletal and actin-binding proteins, a mesenchymal or hybrid EMT phenotype and invasive properties of lung adenocarcinomas. PMID:25744723

    The incidence of several extracolonic tumors, such as duodenal carcinoma, is higher in familial adenomatous polyposis (FAP) patients than in the general population, but there is little information about lung carcinoma in FAP. A 43-year-old woman presented with a lung tumor 17 years after total colectomy for FAP. Pathohistological analysis of the lung tumor demonstrated mixed adenocarcinoma consisting of a papillary adenocarcinoma component and a bronchioloalveolar carcinoma component. Sequencing analysis indicated a germline APC mutation from TCA to TGA (stop) at codon 1110, but no pathogenic germline MYH mutations. The other APC allele in the lung carcinoma was not inactivated by somatic mutations, promoter methylation, or chromosomal deletion. No somatic mutations in any of the coding regions of the p53 gene or in the mutation hot spot regions of the K-ras or EGFR genes were detected in the carcinoma. Amplification, however, of three chromosome regions, 5p, 8q, and 12q14-12q21, was identified in the carcinoma on genome-wide high-resolution single-nucleotide polymorphism (SNP) microarray. The present results suggest that the chromosomal copy number alterations detected on SNP microarray were involved in the carcinogenesis of the adenocarcinoma of the lung in the present FAP patient.

    Our previous study revealed that two splicing factors, polypyrimidine tract-binding protein (PTB) and SRp20, were upregulated in epithelial ovarian cancer (EOC) and knockdown of PTB expression inhibited ovarian tumor cell growth and transformation properties. In this report, we show that knockdown of SRp20 expression in ovarian cancer cells also causes substantial inhibition of tumor cell growth and colony formation in soft agar and the extent of such inhibition appeared to correlate with the extent of suppression of SRp20. Massive knockdown of SRp20 expression triggered remarkable apoptosis in these cells. These results suggest that overexpression of SRp20 is required for ovarian tumor cell growth and survival. Immunohistochemical staining for PTB and SRp20 of two specialized tissue microarrays, one containing benign ovarian tumors, borderline/low malignant potential (LMP) ovarian tumors as well as invasive EOC and the other containing invasive EOC ranging from stage I to stage IV disease, reveals that PTB and SRp20 are both expressed differentially between benign tumors and invasive EOC, and between borderline/LMP tumors and invasive EOC. There were more all-negative or mixed staining cases (at least two evaluable section cores per case) in benign tumors than in invasive EOC, whereas there were more all-positive staining cases in invasive EOC than in the other two disease classifications. Among invasive EOC, the majority of cases were stained all positive for both PTB and SRp20, and there were no significant differences in average staining or frequency of positive cancer cells between any of the tumor stages. Therefore, the expression of PTB and SRp20 is associated with malignancy of ovarian tumors but not with stage of invasive EOC. PMID:20856201

    Background Advanced stage/recurrent clear cell ovarian cancers (CCOCs) are characterized by a low response to chemotherapy and a poor prognosis. There is growing interest in investigating novel/molecular targeted therapies in patients with CCOC in histotype-specific trials. However, CCOCs are not a uniform entity and comprise a number of molecular subtypes and it is unlikely that a single approach to treatment will be appropriate for all patients. The aim of this study was to analyze the results of a multiplatform profiling panel in CCOCs to identify potential therapeutic targets. Patients and Methods Tumor profiling was performed on 521 CCOCs. They were grouped into pure (n = 422) and mixed (n = 99) CCOC for analysis. Testing included a combination of DNA sequencing (including next-generation sequencing) using a 46-gene panel, immunohistochemistry, fluorescent or chromogenic in situ hybridization, and RNA fragment analysis. Results The most common findings were in the PIK3CA/Akt/mTOR pathway, with 61% of all CCOCs showing a molecular alteration in one of these pathway components. Next-generation sequencing revealed PIK3CA mutations in 50% of pure CCOCs. Significant differences were observed between pure and mixed CCOCs with respect to hormone receptor expression (9% vs 34.7% for ER, 13.45 vs 26.4% for PR), cMET (24.1% vs 11.6%), PD-1 tumor infiltrating lymphocytes (48.1% vs 100%), expression of PD-L1 (7.4% vs 25%), and TOPO1 (41% vs 27.1%) on immunohistochemistry, whereas next-generation sequencing revealed significant differences in mutation frequency in PIK3CA (50% vs 18.5%), TP53 (18.1% vs 57.7%), KRAS (12.4% vs 3.7%), and cMET (1.9% vs 11.1%). Conclusions This large study confirms that the PIK3CA/Akt/mTOR pathway is commonly altered in CCOCs, and highlights the significant differences between pure and mixed CCOCs. Clear cell ovarian cancers are molecularly heterogeneous and there are a number of potential therapeutic targets which could be tested in clinical

    Adenoma malignum is a highly differentiated mucinous adenocarcinoma of the cervix with a deceptively innocent histologic appearance but a highly aggressive behavior. We describe a patient who had adenoma malignum associated with Peutz-Jeghers syndrome (PJS) and bilateral ovarian sex cord tumor with annular tubules (SCTAT). The relatively frequent occurrence of cervical adenoma malignum in women with PJS warrants close surveillance by gynecologists for early detection and treatment of this cancer. We report the 16th known case of PJS with adenoma malignum and only the 8th known case of PJS with adenoma malignum and bilateral SCTAT. The highly aggressive nature of cervical adenoma malignum is exemplified, and the difficulties associated with early diagnosis are discussed. The clinical significance of cervical and ovarian tumors associated with PJS is reviewed. PMID:8188091

    A 76-year-old female presented to our hospital with a 2 cm firm, nontender, protuberant umbilical nodule. She received treatment with antibiotics for suspected granuloma, with no improvement after two months. High levels of CA125 as well as an ovarian cyst and intrathoracic and intra-abdominal lesions on imaging studies made us suspect an ovarian cancer with a Sister Mary Joseph nodule (SMJN) and other metastases. A bilateral salpingo-oophorectomy and umbilical and omentum tumor resections were performed and a metastatic ovarian serous adenocarcinoma was diagnosed by histopathology. After surgery, the patient received chemotherapy with paclitaxel, carboplatin, and bevacizumab; however paclitaxel allergy was observed. As a result, chemotherapy continued with carboplatin and bevacizumab every three weeks for a total of 6 courses. Currently, she is still undergoing treatment with bevacizumab and CA125 levels have been progressively decreasing. SMJN is a rare umbilical metastasis which needs to be considered as a differential diagnosis in the presence of an umbilical tumor for prompt treatment initiation.

    Purpose: To report the outcomes and toxicities in patients treated with intensity-modulated radiotherapy (IMRT) for pancreatic adenocarcinoma. Methods and Materials: Forty-seven patients with pancreatic adenocarcinoma were treated with IMRT between 2003 and 2008. Of these 47 patients, 29 were treated adjuvantly and 18 definitively. All received concurrent 5-fluorouracil chemotherapy. The treatment plans were optimized such that 95% of the planning target volume received the prescription dose. The median delivered dose for the adjuvant and definitive patients was 50.4 and 54.0 Gy, respectively. Results: The median age at diagnosis was 63.9 years. For adjuvant patients, the 1- and 2-year overall survival rate was 79% and 40%, respectively. The 1- and 2-year recurrence-free survival rate was 58% and 17%, respectively. The local-regional control rate at 1 and 2 years was 92% and 80%, respectively. For definitive patients, the 1-year overall survival, recurrence-free survival, and local-regional control rate was 24%, 16%, and 64%, respectively. Four patients developed Grade 3 or greater acute toxicity (9%) and four developed Grade 3 late toxicity (9%). Conclusions: Survival for patients with pancreatic cancer remains poor. A small percentage of adjuvant patients have durable disease control, and with improved therapies, this proportion will increase. Systemic therapy offers the greatest opportunity. The present results have demonstrated that IMRT is well tolerated. Compared with those who received three-dimensional conformal radiotherapy in previously reported prospective clinical trials, patients with pancreatic adenocarcinoma treated with IMRT in our series had improved acute toxicity.

    Differentiation grade of colorectal adenocarcinoma (CRC) is a prognostic factor and important for therapy selection. In patients with stage II colon cancer, poor differentiation is an indication for adjuvant chemotherapy. The variability in daily practice in the grading of CRC was assessed in a nationwide cohort. Using the Dutch Pathology Registry (PALGA), all synoptically reported CRC resections from 2010 to 2013 were identified. Proportions of poorly differentiated (PD) adenocarcinomas were determined and compared between 35 laboratories by univariable and multivariable logistic regression analyses. In total, 11,719 resections of 11,681 patients were included, of which 1427 (12.2%) were PD (range between 35 laboratories: 5.0% to 33.2%). After adjustment for case mix, 4 (11%) laboratories still reported a significantly lower (n=2) or higher (n=2) proportion of PD adenocarcinoma compared with the reference laboratory. Seven of 8 investigated laboratories showed considerable intralaboratory variation between pathologists as well. In a subgroup of 2812 patients (2813 tumors) who could have been eligible for adjuvant chemotherapy solely on the basis of the differentiation grade (stage II colon cancer patients without other high-risk factors [ie, T4, <10 lymph nodes evaluated, perforation, ileus, or angioinvasion]), 258 (9.2%) were PD (range between laboratories: 0% to 22.7%). In this subgroup, 4 laboratories still diagnosed significantly more PD adenocarcinomas after multivariable logistic regression analysis, increasing the number of colon cancer patients eligible for adjuvant therapy. In conclusion, this large nationwide cohort demonstrates considerable interlaboratory and intralaboratory variation in differentiation grading of CRC. Better standardization of grading criteria is needed for optimal determination of prognosis and treatment selection. PMID:26975039

    AIM: To examine the extent of use of specific therapies in clinical practice, and their relationship to therapies validated in clinical trials. METHODS: The US National Cancer Institutes’ Patterns of Care study was used to examine therapies and survival of patients diagnosed in 2001 with histologically-confirmed gastroesophageal adenocarcinoma (n = 1356). The study re-abstracted data and verified therapy with treating physicians for a population-based stratified random sample. RESULTS: Approximately 62% of patients had stomach adenocarcinoma (SAC), while 22% had gastric-cardia adenocarcinoma (GCA), and 16% lower esophageal adenocarcinoma (EAC). Stage IV/unstaged esophageal cancer patients were most likely and stage I-III stomach cancer patients least likely to receive chemotherapy as all or part of their therapy; gastric-cardia patients received chemotherapy at a rate between these two. In multivariable analysis by anatomic site, patients 70 years and older were significantly less likely than younger patients to receive chemotherapy alone or chemoradiation for all three anatomic sites. Among esophageal and stomach cancer patients, receipt of chemotherapy was associated with lower mortality; but no association was found among gastric-cardia patients. CONCLUSION: This study highlights the relatively low use of clinical trials-validated anti-cancer therapies in community practice. Use of chemotherapy-based treatment was associated with lower mortality, dependent on anatomic site. Findings suggest that physicians treat lower esophageal and SAC as two distinct entities, while gastric-cardia patients receive a mix of the treatment strategies employed for the two other sites.

    Drug discovery in the ovarian cancer arena has led to the activation of several important clinical trials. Many biologic agents have come down the pipeline and are being studied in phase II trials for recurrent disease. These agents include antivascular compounds that disrupt angiogenesis through a variety of mechanisms (e.g., prevention of ligand-binding to the vascular endothelial growth factor receptor-2 (VEGF-R2), high-affinity VEGF blockade, oral inhibitors of tyrosine kinases stimulated by VEGF, inhibition of alpha5beta1 integrin, neutralization of angioproteins, etc.). Other novel drugs include oral platinum compounds as well as those that antagonize the tumor proliferation genes in the Hedgehog pathway, and that target folic acid receptors which are expressed by ovarian cancer cells. In addition, studies are underway with oral agents that inhibit the tyrosine kinase activity associated with two oncogenes (epidermal growth factor receptor (EGFR) and HER-2/neu). Finally, emerging technologies in clinical trials include nanotechnology to enhance delivery of chemotherapy to ovarian tumors, drug resistance/sensitivity assays to guide therapy, and agents that mobilize and induce proliferation of hematopoetic progenitor cells to aid in red blood cell, white blood cell, and platelet recovery following chemotherapy. The relevant patents in drug discovery of ovarian cancer are discussed. PMID:20524931

    Patients with pancreatic adenocarcinoma are known to have a high mortality rate. The 5-year survival rate still remains low even now compared to that of the 1960's despite new advances in management including surgery, chemotherapy, pathological classification and molecular diagnostic technologies. Precursors to invasive pancreatic adenocarcinoma have been identified in the last ten years that include mucinous cystic neoplasm, intraductal papillary mucinous neoplasm and pancreatic intraepithelial neoplasia. p53 protein accumulation in the nuclei is a common molecular event in most human neoplasms. Our objective is to investigate p53 expression in pancreatic adenocarcinoma and precursor lesions and their significance. The selected study material encompassed 31 invasive ductal adenocarcinoma, 15 mucinous cystic neoplasm and papillary mucinous neoplasm, and 27 cases of pancreatic intraepithelial neoplasia including grade 1, 2 and 3. Immunoscore was given for each case based on intensity of staining and percentage of cells positive and compared between precursor lesions and invasive adenocarcinoma. A score of 50 and above was considered significant. The results showed that p53 expression increased progressively and significantly with the grade of pancreatic intraepithelial neoplasia and adenocarcinoma (p-value < 0.001). These findings support the concept of multistep carcinogenesis in pancreatic adenocarcinoma and suggest that p53 inactivation occurs in the progression of precursors to pancreatic adenocarcinoma.

    Although embryonal proteins have been used as tumor marker, most are not useful for detection of early malignancy. In the present study, we developed mouse monoclonal antibodies against fetal lung of miniature swine, and screened them to find an embryonal protein that is produced at the early stage of malignancy, focusing on lung adenocarcinoma. We found an antibody clone that specifically stained stroma of lung adenocarcinoma. LC-MS/MS identified the protein recognized by this clone as dimethylarginine dimethylaminohydrolase 2 (DDAH2), an enzyme known for antiatherosclerotic activity. DDAH2 was found to be expressed in fibroblasts of stroma of malignancies, with higher expression in minimally invasive adenocarcinoma (MIA) and invasive adenocarcinoma than in adenocarcinoma in situ (AIS). Moreover, tumors with high stromal expression of DDAH2 had a poorer prognosis than those without. In vitro analysis showed that DDAH2 increases expression of endothelial nitric oxide synthase (eNOS), inducing proliferation and capillary-like tube formation of vascular endothelial cells. In resected human tissues, eNOS also showed higher expression in invasive adenocarcinoma than in AIS and normal lung, similarly to DDAH2. Our data indicate that expression of DDAH2 is associated with invasiveness of lung adenocarcinoma via tumor angiogenesis. DDAH2 expression might be a prognostic factor in lung adenocarcinoma.

    The pattern of ovarian cancer metastasis is markedly different from that of most other epithelial tumors, because it rarely spreads hematogenously. Instead, ovarian cancer cells exfoliated from the primary tumor are carried by peritoneal fluid to metastatic sites within the peritoneal cavity. These sites, most notably the abdominal peritoneum and omentum, are organs covered by a mesothelium-lined surface. To investigate the processes of ovarian cancer dissemination, we assembled a complex three-dimensional culture system that reconstructs the lining of the peritoneal cavity in vitro. Primary human fibroblasts and mesothelial cells were isolated from human omentum. The fibroblasts were then mixed with extracellular matrix and covered with a layer of the primary human mesothelial cells to mimic the peritoneal and omental surfaces encountered by metastasizing ovarian cancer cells. The resulting organotypic model is, as shown, used to examine the early steps of ovarian cancer dissemination, including cancer cell adhesion, invasion, and proliferation. This model has been used in a number of studies to investigate the role of the microenvironment (cellular and acellular) in early ovarian cancer dissemination. It has also been successfully adapted to high throughput screening and used to identify and test inhibitors of ovarian cancer metastasis. PMID:26780294

    The aim of this study was to investigate NUT (nuclear protein in the testis) expression in ovarian germ cell tumours (GCTs). Immunostaining for NUT protein was performed in 10 mature cystic teratomas and in 49 malignant ovarian GCTs including 15 pure dysgerminomas, six dysgerminomas associated with gonadoblastoma, nine yolk sac tumours, 12 immature teratomas, and seven mixed malignant tumours. Only nuclear staining was considered a positive finding although cytoplasmic staining was noted when present. Thirty-seven (76%) malignant GCTs were NUT positive but staining was usually of weak to moderate intensity and observed in a relatively small proportion of neoplastic cells. Staining in immature teratomas and yolk sac tumours was restricted to foci of hepatoid and intestinal/glandular differentiation, where both nuclear and cytoplasmic reactivity were observed. In dysgerminoma associated with gonadoblastoma only the in situ and invasive germ cell elements were NUT positive. Nuclear staining was not seen in benign teratomas. Most malignant ovarian GCTs express NUT protein, albeit focally, and this should be considered when evaluating immunostaining in the differential diagnosis of poorly differentiated malignancies, particularly NUT midline carcinoma. Since NUT protein appears to play a role in normal germ cell maturation it may influence intestinal or hepatoid differentiation within malignant GCTs. PMID:25551299

    We investigated the clinical observations and the results of a comprehensive survey of 70 patients with ovarian cancer stage III-IV aged 30 to 70 years with the presence of endotoxemia. Integral assessment of prognosis and severity of the condition was performed according to SAPS II and SOFA. Infusion program included a preliminary correction of hypovolemia prior to surgery on the operating table in equal parts, HES and balanced crystalloid solutions, with in- creased infusion of 15% of blood volume based on the method of anesthesia. In the early postoperative period, infusion programs were complemented by various embodiments of metabolic correction. Patients of group-1 (n = 35) received remaxol in a dose of 800 mI/day. Patients of group-2 (n = 35) received ademethionine (heptral) 800 mg/day. Analysis of the results revealed that premorbid background in patients with ovarian cancer stage III-IV was characterized by hypovolemia, phenomena hepatopathy, and endotoxemia, and mixed forms of hypoxia of varying severity. Differentiated approach to the choice of pathogenesis-based perioperative infusion according to premorbid condition, anesthesia and blood loss contributed to the elimination of hypovolemia, favored efficient oxygen delivery and consumption, the ade- quacy of tissue oxygenation. Remaxol inclusion in the perioperative infusion programs in patients with ovarian cancer enhanced their clinical efficiency, reduced cytolytic and cholestatic syndromes, recovered of protein and synthetic liver function, reduced the appearance of mixedforms of hypoxia and endogenous intoxication.

    Adenocarcinoma of the exocrine pancreas has an annual incidence of 7,400 cases in the U.K. In comparison with other common cancers of solid organs, namely, breast, colorectal, and prostate cancer, pancreatic cancer has a high morbidity and mortality. Radical resection is possible in only 15%-20% of patients, and only 3%-4% of all patients presenting with this condition achieve long-term control and cure. Various strategies in the form of neoadjuvant and adjuvant treatment have been employed over the years to improve outcome, with limited success. Systemic chemotherapy remains the gold standard in the metastatic setting in good performance status patients, and adjuvant chemotherapy after resection of localized and locally advanced cancer has been found to improve outcome. The role of radiotherapy, however, remains controversial and is an area that merits further investigation in well-conducted multicenter trials at various stages of the disease in combination with systemic agents and exploiting recent advances in the delivery of radiotherapy. In this article, we review the published literature on the use of chemoradiation as a modality in various stages of pancreatic adenocarcinoma and highlight areas that future trials in this field should target for a way forward in this malignancy.

    Pancreatic adenocarcinoma is the fourth leading cause of cancer mortality in the United States in both men and women, with a 5-year survival rate of less than 5%. Surgical resection remains the only curative treatment, but most patients develop systemic recurrence within 2 years of surgery. Adjuvant treatment with chemotherapy or chemoradiotherapy has been shown to improve overall survival, but the delivery of treatment remains problematic with up to 50% of patients not receiving postoperative treatment. Neoadjuvant therapy can provide benefits of eradication of micrometastasis and improved delivery of intended treatment. We have reviewed the findings from completed neoadjuvant clinical trials, and discussed the ongoing studies.

    Abstract Introduction: Aggressive digital papillary adenocarcinoma (ADPA) is a rare sweat gland tumor that is found on the fingers, toes, and the digits. To date, <100 cases have been reported in the literature. Apart from 1 case reported in the thigh, all of them were on digital or nondigital acral skin. Case presentation: A 67-year-old Caucasian woman was admitted to the hospital due to a mass on the scalp. This lesion was present for almost a year. It was a semimobile cyctic mass that elevated the scalp. There was no change in the skin color. Its dimensions were 1.5 × 1 × 0.6 cm. The laboratory, clinic, and radiologic findings (head x-ray) of the patient were normal. It was evaluated as a benign lesion such as lipoma or epidermal cyst by a surgeon due to a small semimobile mass and no erosion of the skull. It was excised by a local surgery excision. The result of the pathologic examination was aggressive papillary adenocarcinoma. This diagnosis is synonymous with ADPA. Conclusion: In our case, localization was scalp. This localization is the first for this tumor in the literature. In addition, another atypical localization of this tumor (ADPA) is thigh in the literature. This case was presented due to both the rare and atypical localizations. That is why, in our opinion, revision of “digital” term in ADPA is necessary due to seem in atypical localizations like thigh and scalp. PMID:27428196

    Pancreatic adenocarcinoma is the fourth leading cause of cancer mortality in the United States in both men and women, with a 5-year survival rate of less than 5%. Surgical resection remains the only curative treatment, but most patients develop systemic recurrence within 2 years of surgery. Adjuvant treatment with chemotherapy or chemoradiotherapy has been shown to improve overall survival, but the delivery of treatment remains problematic with up to 50% of patients not receiving postoperative treatment. Neoadjuvant therapy can provide benefits of eradication of micrometastasis and improved delivery of intended treatment. We have reviewed the findings from completed neoadjuvant clinical trials, and discussed the ongoing studies. Combinational cytotoxic chemotherapy such as fluorouracil, leucovorin, irinotecan, and oxaliplatin and gemcitabine plus nanoparticle albumin-bound (nab)-paclitaxel, active in the metastatic setting, are being studied in the neoadjuvant setting. In addition, novel targeted agents such as inhibitor of immune checkpoint are incorporated with cytotoxic chemotherapy in early-phase clinical trial. Furthermore we have explored the utility of biomarkers which can personalize treatment and select patients for target-driven therapy to improve treatment outcome. The treatment of resectable pancreatic adenocarcinoma requires multidisciplinary approach and novel strategies including innovative trials to make progress. PMID:26862486

    Faced with the catastrophic prognosis for ovarian cancer due to the fact that it is most often diagnosed late at the peritoneal carcinomatosis stage, screening and early detection could probably reduce the mortality rate. A better understanding of the molecular characteristics of the different ovarian cancer subtypes and their specific molecular signatures is indispensable prior to development of new screening strategies. We discuss here the early natural history of ovarian cancer and its origins. PMID:24804229

    Background: Vascular endothelial growth factor (VEGF) has an essential role in tumor metastasis by inducing the construction of abnormal blood vessels. Epidermal growth factor receptor (EGFR) is involved in different parts of cancer growth such as tumor initiation, angiogenesis and metastasis. Objectives: The aim of this study was to evaluate the expression of VEGF and EGFR in ovarian cancer in southern Iran and to assess the correlation between expression of these two markers and patients’ age, tumor stage, and grade. Patients and Methods: In this cross-sectional study, 50 paraffin blocks of serous ovarian adenocarcinomas and 50 paraffin-embedded specimens from control individuals operated for reasons other than malignancy were immunohistochemically stained using anti-human VEGF and EGFR antibodies. Results: A significant difference in the frequency of positive expression of VEGF was observed in ovarian cancer patients (25.0%) compared with the control group (8.0%) (P = 0.023). A significant difference between EGFR expression in patients (56.8%) and controls (24.0%) was also obtained (P = 0.001). No significant correlation between VEGF and EGFR expression and patients’ age, tumor grade and stage were detected (P > 0.05). Conclusions: The significant increase in both VEGF and EGFR in the patients with ovarian cancer compared to healthy individuals could have prognostic value. Identifying these markers may be useful for chemopreventive and chemotherapeutic strategies for patients with serous ovarian cancer. PMID:26478789

    Surgery is the cornerstone of treatment for patients with advanced ovarian cancer. The majority of patients with advanced ovarian cancer who experience a clinical remission after initial surgery will develop a recurrence. The optimal management for patients with recurrent ovarian cancer remains to be defined. Chemotherapy is frequently used with varying response rates. Repeat surgical cytoreduction appears to offer a survival benefit for select patients with recurrent ovarian cancer and should be considered. Surgery also plays a role in the palliation of certain patients. Continued investigations, especially randomized trials, are needed to further define the optimal treatment modalities for these patients. PMID:19332245

    Prostate apoptosis response-4 (PAR-4) is considered as a tumour suppressor due to its ability to selectively induce cell apoptosis in most cancer cells. However little is known about the role of PAR-4 in ovarian cancer. In this study, we investigated for the first time the role of PAR-4 in ovarian carcinogenesis. We showed that PAR-4 mRNA level is not significantly different between healthy and cancer ovarian cells. Immunohistochemistry on ovarian tissue showed that ovarian cancer cells are positive for PAR-4 nuclear and cytoplasmic staining whereas ovarian healthy cells are negative for PAR-4 nuclear staining. We then studied the role of PAR-4 in cell apoptosis. We determined that PAR-4 induces cell apoptosis in response to stimuli, in vitro, but is also involved in the relocation of GRP78 from endoplasmic reticulum to the cell surface of ovarian cancer cell line (SKOV-3 cells). In ovo, PAR-4 decreases ovarian tumour development and increases the response to taxol treatment. These observations suggest that PAR-4 is a very interesting therapeutic target against ovarian carcinogenesis. PMID:26246468

    Ovarian cancer is the most common cause of death among gynecological malignancies. We discuss different types of clinical and nonclinical features that are used to study and analyze the differences between benign and malignant ovarian tumors. Computer-aided diagnostic (CAD) systems of high accuracy are being developed as an initial test for ovarian tumor classification instead of biopsy, which is the current gold standard diagnostic test. We also discuss different aspects of developing a reliable CAD system for the automated classification of ovarian cancer into benign and malignant types. A brief description of the commonly used classifiers in ultrasound-based CAD systems is also given. PMID:25230716

    Ovarian cancer is the fifth largest cancer killer in women. Improved understanding of the molecular pathways implicated in the pathogenesis of ovarian cancer has led to the investigation of novel targeted therapies. Ovarian cancer is characterized by an imbalance between pro- and antiangiogenic factors in favor of angiogenesis activation. Various antivascular strategies are currently under investigation in ovarian cancer. They can schematically be divided into antiangiogenic and vascular-disrupting therapies. This paper provides a comprehensive review of these new treatments targeting the tumor vasculature in this disease. Promising activities have been detected in phase II trials, and results of phase III clinical trials are awaited eagerly. PMID:20072701

    The effect of calusterone (7beta,17alpha-dimethyltestosterone) on rat mammary DMBA-induced adenocarcinoma was studied both in vivo and in organ culture. In vivo all 8 tumours with a diameter of less than 30 mm regressed following calusterone injection (10 mg/day for 2-3 weeks). In organ culture calusterone (20 mug/ml medium) inhibited the synthesis of DNA and RNA in all 7 cases examined. Testosterone also inhibited the synthesis of DNA and RNA in organ culture in 12 out of 14 and 10 out of 14 tumours respectively. Oestradiol-17beta on the other hand had no effect on DNA and RNA synthesis in organ culture although 70% of the tumours examined were ovarian dependent, i.e. regressed following castration. This could be explained by the direct effect of calusterone on rat adenocarcinoma compared with the indirect effect of oestradiol-17beta which probably exerts its action by activating the secretion of prolactin which acts on the tumour.

    Shortly after treatment with the cytostatic combination of cisplatin and paclitaxel was generally accepted as the standard therapy for patients with epithelial ovarian carcinoma, many have come to regard the combination of carboplatin and paclitaxel as a better choice. The latter combination causes fewer side effects and may be used in the outpatient clinic. Conceivably, the carboplatin-paclitaxel scheme will shortly have to be adjusted again owing to results of current research. The intensive basic research of recent years, namely, is beginning to yield benefits for the therapeutic arsenal against ovarian carcinoma. Possibilities are inhibitors of the breakdown of extracellular matrix (such as marimastat) and inhibitors of signal transduction (such as trastuzumab). PMID:10578409

    Controversies exist regarding the surgical treatment of the ovaries in women with primary colorectal cancer. A review of the authors' experience and the surgical literature reveals an incidence of ovarian metastases from colorectal cancer of approximately 6 percent. This problem may occur somewhat more frequently in premenopausal women. Resection of the ovaries at the time of colectomy is unlikely to affect survival. Removal of the ovaries at the time of bowel resection will prevent repeat laparotomy to resect an ovarian mass in approximately 2 percent of women with large bowel cancer. Oophorectomy should be performed in all postmenopausal females at the time of primary resection. Oophorectomy should be performed in premenopausal women if any gross abnormality of the ovary is detected or if peritoneal implants are seen at the time of primary resection. PMID:3533472

    Infertility adversely affects many couples worldwide. Conversely, the exponential increase in world population threatens our planet and its resources. Therefore, a greater understanding of the fundamental cellular and molecular events that control the size of the primordial follicle pool and follicular development is of utmost importance to develop improved in vitro fertilization as well as to design novel approaches to regulate fertility. In this review we attempt to highlight some new advances in basic research of the mammalian ovary that have occurred in recent years focusing primarily on mouse models that have contributed to our understanding of ovarian follicle formation, development, and ovulation. We hope that these new insights into ovarian function will trigger more research and translation to clinically relevant problems. PMID:20839083

    Background: Artificial insemination is a commonly performed procedure for the treatment of various forms of infertility. Infectious complications have only rarely been noted as a complication of intrauterine insemination (IUI). Case: In this presentation, we report the first case of an ovarian abscess following IUI with the husband's semen. Despite treatment with triple antibiotics, an oophorectomy was required. Surgical as well as pathological evaluation confirmed the diagnosis of an ovarian abscess. Following surgery, the patient responded well to antibiotic therapy. Conclusion: Since pelvic infections are ascending processes, the violation of the natural cervical barrier with IUI can theoretically place the patient at increased risk for this complication. While few advocate routine cultures of semen samples, the clinician must be acutely alert to potential infectious morbidity following this procedure. Early diagnosis and intervention are necessary to minimize morbidity and optimize treatment. PMID:18472883

    A lot is known about the control of the development of ovarian follicles by growth factors and hormones, but less is known about the roles of extracellular matrix in the control of follicular growth and development. In this review we focus on the specialized extracellular matrix of the basal laminas that are present in ovarian follicles. These include the follicular basal lamina itself, the Call-Exner bodies of the membrana granulosa, the subendothelial and arteriole smooth muscle basal laminas in the theca, and the basal lamina-like material of the thecal matrix. We discuss the evidence that during follicle development the follicular basal lamina changes in composition, that many of its components are produced by the granulosa cells, and that the follicular basal laminas of different follicles have different ultrastructural appearances, linked to the shape of the aligning granulosa cells. All these studies suggest that the follicular basal lamina is extremely dynamic during follicular development. PMID:10963877

    Chemo- and radiation therapies used to treat cancer can have the unintended effect of making patients infertile. Clinically established fertility preservation methods, such as egg and embryo cryopreservation, are not applicable to all patients, which has motivated the development of strategies that involve ovarian tissue removal and cryopreservation before the first sterilizing treatment. To restore fertility at a later date, the early-stage follicles present in the tissue must be matured to produce functional oocytes, a process that is not possible using existing cell culture technologies. This review describes the application of tissue engineering principles to promote ovarian follicle maturation and produce mature oocytes through either in vitro culture or transplantation. The design principles for these engineered systems are presented, along with identification of emerging opportunities in reproductive biology. PMID:24849592

    Ovarian transposition in adults has been shown to protect ovarian function in about 60% of cases by reducing ovarian exposure to less than 4 to 7 Gy. We therefore evaluated the effect of ovarian transposition during childhood or adolescence. Eighteen girls had ovarian transposition performed at a mean (+/- SEM) age of 9.4 +/- 1.2 years (range, 1.2 to 16 years). Twelve were prepubertal and six had menstruated at the time of ovarian transposition. The initial abnormalities were Hodgkin disease (5 cases), iliac Ewing sarcoma (3), medulloblastoma (2), ovarian seminoma (1), and vaginal or uterine tumor (7). The irradiation was external in 11 cases and local by vaginal curietherapy in 7 cases. Fifteen girls received chemotherapy. The ovarian transposition was bilateral in 15 patients and unilateral in 3 cases; in the latter the other ovary had been destroyed by the tumor or by abdominal irradiation. Ovaries were placed just below the iliac crest (15 cases) or posterolateral to the uterus (3); thus, the calculated ovarian radiation dose was up to 9.5 Gy. At the time of evaluation (8.6 +/- 0.9 years after ovarian transposition), 16 girls had menstruated and 2 remained amenorrheic because of major lesions of the vagina and uterus caused by the vaginal curietherapy. Basal plasma gonadotropin values were normal. Ovulation was documented in seven cases. Two pregnancies occurred. Complications of ovarian transposition were present in four patients: intestinal occlusion, dyspareunia, functional ovarian cysts, and pelvic adhesions with tubal obstruction. We conclude that ovarian transposition, performed before abdominopelvic irradiation during childhood, can preserve ovarian function. Longer follow-up is required to assess the risk of ovarian dystrophy because of vascular lesions or chemotherapy. PMID:1447649

    5T4 oncofetal antigen is defined by a monoclonal antibody raised against human placental trophoblast, and recognizes a 72 kD glycoprotein expressed in many different carcinomas but detected only at low levels in some normal epithelia. Analysis of the patterns of expression of 5T4 oncofetal antigen in colorectal carcinomas has indicated a significant association between the presence of the antigen in tumor cells and metastatic spread. The 5T4 antigen expression of 72 epithelial ovarian carcinomas has been investigated by immunohistochemistry; 71% of the carcinomas demonstrated positive 5T4 immunoreactivity in adenocarcinoma cells and/or associated stromal tissue. In order to assess any relationship to prognosis, the 5T4 phenotypes were analyzed with respect to various clinicopathologic features of the tumors and the clinical outcome of the patients assessed by survival and disease-free interval. There was a significant correlation between 5T4 expression and more advanced stage of disease (FIGO stages III and IV) (P < 0.001) and with poorly differentiated tumors (P = 0.036) compared to well or moderately differentiated tumors. Patients with tumors expressing 5T4 were less likely to respond well to adjuvant therapy (P = 0.030) and had a significantly worse outlook in terms of survival (P = 0.033) and disease-free interval (P = 0.033). This significance was not demonstrated as acting independently of FIGO stage and tumor differentiation. PMID:11578488

    The aim of this study was to estimate the effect of exposure to secondhand tobacco smoke on the incidence of lung adenocarcinoma in situ/minimally invasive adenocarcinoma (AIS/MIA). Data from seven case-control studies participating in the International Lung Cancer Consortium (ILCCO) were pooled, resulting in 625 cases of AIS/MIA and 7,403 controls, of whom 170 cases and 3,035 controls were never smokers. Unconditional logistic regression was used to estimate adjusted ORs (ORadj) and 95% confidence intervals (CI), controlling for age, sex, race, smoking status (ever/never), and pack-years of smoking. Study center was included in the models as a random-effects intercept term. Ever versus never exposure to secondhand tobacco smoke was positively associated with AIS/MIA incidence in all subjects (ORadj = 1.48; 95% CI, 1.14-1.93) and in never smokers (ORadj = 1.45; 95% CI, 1.00-2.12). There was, however, appreciable heterogeneity of ORadj across studies (P = 0.01), and the pooled estimates were largely influenced by one large study (40% of all cases and 30% of all controls). These findings provide weak evidence for an effect of secondhand tobacco smoke exposure on AIS/MIA incidence. Further studies are needed to assess the impact of secondhand tobacco smoke exposure using the newly recommended classification of subtypes of lung adenocarcinoma. PMID:26503035

    2015-01-01

    Primordial follicles or non-growing follicles (NGFs) are the functional unit of reproduction, each comprising a single germ cell surrounded by supporting somatic cells. NGFs constitute the ovarian reserve (OR), prerequisite for germ cell ovulation and the continuation of the species. The dynamics of the reserve is determined by the number of NGFs formed and their complex subsequent fates. During the reproductive lifespan, the OR progressively diminishes due to follicle atresia as well as recruitment, maturation, and ovulation. The depletion of the OR is the major determining driver of menopause, which ensues when the number of primordial follicles falls below a threshold of ∼1,000. Therefore, genes and processes involved in follicle dynamics are particularly important to understand the process of menopause, both in the typical reproductive lifespan and in conditions like primary ovarian insufficiency, defined as menopause before age 40. Genes and their variants that affect the timing of menopause thereby provide candidates for diagnosis of and intervention in problems of reproductive lifespan. We review the current knowledge of processes and genes involved in the development of the OR and in the dynamics of ovarian follicles. PMID:26528328

    Ovarian yolk sac tumors (YSTs) are rare neoplasms. No radiological study has been done to compare the imaging findings between this type of tumor and other ovarian tumors. Here we analyzed the CT findings of 11 pathologically proven ovarian YSTs and compared their imaging findings with 18 other types of ovarian tumors in the same age range. Patient age, tumor size, tumor shape, ascites and metastasis of two groups did not differ significantly (P > 0.05). A mixed solid-cystic nature, intratumoral hemorrhage, marked enhancement and dilated intratumoral vessel of two groups differed significantly (P < 0.05). The area under the ROC curve of four significant CT features was 0.679, 0.707, 0.705, and 1.000, respectively. Multivariate logistic regression analysis identified two independent signs of YST: intratumoral hemorrhage and marked enhancement. Our results show that certain suggestive CT signs that may be valuable for improving the accuracy of imaging diagnosis of YST and may be helpful in distinguishing YST from other ovarian tumors.

    A continuous cell line, COLO 346, was established from a liver metastasis in a patient with adenocarcinoma of the gallbladder. COLO 346 grew as an adherent monolayer of pleomorphic epithelioid cells. COLO 346 cells produced esterone, but no estradiol, progesterone, or cortisol. No adrenocorticotropic hormones, beta-subunit of human chorionic gonadotropin, carcinoembryonic antigen, or alpha-fetoprotein production by the cells was detected. Cell doubling time was 36 h. Seven allelic isozymes were assayed. COLO 346 had a chromosome mode of 74 at 21 months postestablishment with 6 marker chromosomes present in 100% of the cells analyzed. COLO 346 has been in continuous culture for over 2 yr and is available to other investigators for their studies. PMID:7262900

    A 73-year-old postmenopausal Japanese woman presented with a complaint of slight fever and weight loss. An elevated level of CA125 in the blood favored a diagnosis of malignant uterine body tumor, but was not confirmed by endometrial cytology and biopsy. Resection of the uterus revealed a solid whitish tumor in the myometrium that was diagnosed as clear cell adenocarcinoma (CCA) arising from adenomyosis. There were transitions between endometrial epithelium of adenomyosis, noninvasive CCA, and invasive CCA. Immunohistochemical expression of hepatocyte nuclear factor-1beta supported the diagnosis of CCA. Only one other English language document pertaining to CCA arising from adenomyosis exists. Malignant tumor arising from adenomyosis should be considered as a differential diagnosis when the serum level of tumor markers such as CA125 is high and when the tumor is intramyometrial.

    Pancreatic ductal adenocarcinoma (PDAC) is expected to become the second leading cause of cancer death by 2030. Current therapeutic options are limited, warranting an urgent need to explore innovative treatment strategies. Due to specific microenvironment constraints including an extensive desmoplastic stroma reaction, PDAC faces major metabolic challenges, principally hypoxia and nutrient deprivation. Their connection with oncogenic alterations such as KRAS mutations has brought metabolic reprogramming to the forefront of PDAC therapeutic research. The Warburg effect, glutamine addiction, and autophagy stand as the most important adaptive metabolic mechanisms of cancer cells themselves, however metabolic reprogramming is also an important feature of the tumor microenvironment, having a major impact on epigenetic reprogramming and tumor cell interactions with its complex stroma. We present a comprehensive overview of the main metabolic adaptations contributing to PDAC development and progression. A review of current and future therapies targeting this range of metabolic pathways is provided. PMID:26164081

    Adenocarcinoma of the pigmented ciliary epithelium is an exceptionally rare eye tumour, with only a few cases reported to date. We encountered such a case in a 50-year-old woman who reported seeing floaters in her right eye. Fundus examination and MRI revealed an elevated lesion located in the ciliary body compressing the lens. The ciliary body was resected under the diagnosis of ciliary adenoma. On histological examination, the tumour exhibited epithelial features with glandular formation and moderate nuclear pleomorphism. The tumour invaded the subepithelial stroma of the ciliary body. Immunohistochemical findings were positive for cytokeratin OSCAR, AE1/AE3, CK7, EMA, S100, Melan A, HMB45, and microphthalmia-associated transcription factor. PMID:25015166

    Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer death in the USA, accounting for ~40,000 deaths annually. The dismal prognosis for PDAC is largely due to its late diagnosis. Currently, the most sensitive diagnosis of PDAC requires invasive procedures, such as endoscopic ultrasonography, which has inherent risks and accuracy that is highly operator dependent. Here we took advantage of a general characteristic of solid tumors, the acidic microenvironment that is generated as a by-product of metabolism, to develop a novel approach of using pH (Low) Insertion Peptides (pHLIPs) for imaging of PDAC. We show that fluorescently labeled pHLIPs can localize and specifically detect PDAC in human xenografts as well as PDAC and PanIN lesions in genetically engineered mouse models. This novel approach may improve detection, differential diagnosis and staging of PDAC.

    Pancreatic ductal adenocarcinoma (PDAC) is one of the most common causes of cancer related death. Despite the advances in understanding of the molecular pathogenesis, pancreatic cancer remains a major unsolved health problem. Overall, the 5-year survival rate is less than 5% demonstrating the insufficiency of current therapies. Most cytotoxic therapies induce apoptosis and PDAC cells have evolved a plethora of molecular mechanisms to assure survival. We will present anti-apoptotic strategies working at the level of the death receptors, the mitochondria or involving the caspase inhibitors of the IAP family. Furthermore, the survival function of the phosphotidylinositol-3' kinase (PI3K)/AKT- and NF-kappaB-pathways are illustrated. A detailed molecular knowledge of the anti-apoptotic mechanisms of PDAC cells will help to improve therapies for this dismal disease and therapeutic strategies targeting the programmed cell death machinery are in early preclinical and clinical development.

    The study revealed the key role of serine protease hepsin activity in transition of in situ prostate adenocarcinoma into the metastasizing form. Inhibition of hepsin activity suppresses the invasive growth of the tumor. Hepsin is an convenient target for pharmacological agents, so the study of its inhibitory mechanisms is a promising avenue in drug development. Assay of proteolytic activity in various tumor cell lines in vitro showed that this activity in prostate adenocarcinoma cells significantly surpasses proteolytic activity in other examined tumor cell lines. Selective cytotoxic action of anthralin, an inhibitor of hepsin activity, on human adenocarcinoma cells was demonstrated in comparison with other tumor cell lines. PMID:22866312

    A flat, elevated lesion measuring 5 mm in diameter was found in the gastric body of an 80-year-old man. A biopsy showed moderately differentiated adenocarcinoma, and endoscopic ultrasonography revealed a hypoechoic mass located in the submucosa. Endoscopic submucosal dissection was subsequently performed, and a pathological examination revealed a tumor composed of adenocarcinoma and neuroendocrine carcinoma with submucosal infiltration. The pathological diagnosis was gastric mixed adenoneuroendocrine carcinoma (MANEC). An additional gastrectomy procedure was performed, and no recurrence was noted for at least three years. This case is interesting with respect to the carcinogenesis of endocrine cell carcinoma and MANEC. PMID:25400179

    Ovarian cancer is the most lethal gynecological malignancy due to its high metastatic ability. Epithelial-mesenchymal transition (EMT) is essential during both follicular rupture and epithelium regeneration. However, it may also accelerate the progression of ovarian carcinomas. Experimental studies have found that 1α,25-dihydroxyvitamin-D3 [1α,25(OH)₂D₃] can inhibit the proliferation of ovarian cancer cells. In this study, we investigated whether 1α,25(OH)₂D₃ could inhibit the migration of ovarian cancer cells via regulating EMT. We established a model of transient transforming growth factor-β1(TGF-β1)-induced EMT in human ovarian adenocarcinoma cell line SKOV-3 cells. Results showed that, compared with control, 1α,25(OH)₂D₃ not only inhibited the migration and the invasion of SKOV-3 cells, but also promoted the acquisition of an epithelial phenotype of SKOV-3 cells treated with TGF-β1. We discovered that 1α,25(OH)₂D₃ increased the expression of epithelial marker E-cadherin and decreased the level of mesenchymal marker, Vimentin, which was associated with the elevated expression of VDR. Moreover, 1α,25(OH)₂D₃ reduced the expression level of transcription factors of EMT, such as slug, snail, and β-catenin. These results indicate that 1α,25(OH)₂D₃ suppresses the migration and invasion of ovarian cancer cells by inhibiting EMT, implying that 1α,25(OH)₂D₃ might be a potential therapeutic agent for the treatment of ovarian cancer.

  19. Estrogen-producing endometrioid adenocarcinoma resembling sex cord-stromal tumor of the ovary: a review of four postmenopausal cases

    PubMed Central

    2012-01-01

    Abstract The 4 present cases with endometrioid adenocarcinoma (EMA) of the ovary were characterized by estrogen overproduction and resemblance to sex cord-stromal tumor (SCST). The patients were all postmenopausal, at ages ranging from 60 to 79 years (av. 67.5), who complained of abdominal discomfort or distention and also atypical genital bleeding. Cytologically, maturation of the cervicovaginal squamous epithelium and active endometrial proliferation were detected. The serum estrogen (estradiol, E2) value was preoperatively found to be elevated, ranging from 48.7 to 83.0 pg/mL (av. 58.4). In contrast, follicle stimulating hormone was suppressed to below the normal value. MR imaging diagnoses included SCSTs such as granulosa cell tumor or thecoma for 3 cases because of predominantly solid growth, and epithelial malignancy for one case because of cystic and solid structure. Grossly, the solid part of 3 cases was homogeneously yellow in color. Histologically, varying amounts of tumor components were arranged in solid nests, hollow tubules, cord-like strands and cribriform-like nests in addition to the conventional EMA histology. In summary, postmenopausal ovarian solid tumors with the estrogenic manifestations tend to be preoperatively diagnosed as SCST. Due to this, in the histological diagnosis, this variant of ovarian EMA may be challenging and misdiagnosed as SCST because of its wide range in morphology.

    A 28-year-old housewife, a life-long nonsmoker, presented with 3 weeks of pleuritic chest pain along with swollen right leg, left arm, and left breast. Six months previously she had left subclavian vein thrombosis. On admission, bilateral supraclavicular lymphedema on right leg and left arm and breast was observed and bilateral pleural fluid, chylous exudates, was detected. Abdomen computed tomography revealed abundant ascites and right ovarian enlargement. Whole body bone scintigraphy showed bone metastases on left humerus, right femur, and pelvis. Bronchial biopsy, obtained from edematous, hyperemic-irregular mucosa, revealed a carcinoma composed of signet-ring cells with intracytoplasmic mucin. Breast biopsy also showed signet-ring cells within the lymphatics. Pleural fluid cytology showed similar malignant cells. The patient was diagnosed as gastric signet-ring cell adenocarcinoma with endobronchial, mammary, ovarian, pleural, pericardial, peritoneal, and osteal metastases. The authors recommend that deep-vein thrombosis in unusual sites deserves further evaluation for an occult malignancy. PMID:18263634

    Introduction Umbilical hernia is a common finding in many cases, posing potentially life-threatening complications, such as incarceration or strangulation. The presence of malignancy in hernia sacs is, however, rather rare. Presentation of case Here we report on a case of primary peritoneal adenocarcinoma found through histological examination of omental tissue, resected due to an incarcerated umbilical hernia of an 84-years-old woman. There was no macroscopic sign of malignancy during operation; only after routine examination of histological sections the diagnosis was found. Discussion To our knowledge this is the first report of primary peritoneal cancer as content of an umbilical hernia. This is a rare neoplasm and histologically identical to epithelial ovarian carcinoma. For this reason, the diagnosis is usually based on the histological finding and exclusion of a primary ovarian tumor. Primary peritoneal cancer has a poor outcome in general. Early diagnosis is, therefore, essential for effective treatment. Conclusion Histological analysis of resected hernia sac or content should be performed routinely to discover malignant diseases in the background of a hernia. PMID:26748210

    Adenocarcinoma of the anal canal accounts for about 20% of all anal canal cancers. It is subclassified into two types. (1) Colorectal type, which arises from the mucosa above dentate line and (2) extramucosal type, which includes adenocarcinoma arising in anorectal fistulae and adenocarcinoma arising from anal glands. Anal gland adenocarcinomas are extremely rare. In this article, we present two cases of anal adenocarcinoma, one colorectal type, and other anal gland carcinoma along with review of literature.

    The primary objectives of the present study are to determine the period of onset of ovarian insufficiency after surgery and to confirm potential risk factors for ovarian insufficiency after surgery for the removal of benign ovarian cysts. Data were obtained from 75 patients who underwent surgery for benign ovarian cysts prior to the onset of ovarian insufficiency. Our analysis included 835 ovarian insufficiency patients who were referred to our institution from July 2003 to July 2013. Several epidemiological parameters of ovarian insufficiency after surgery (age at operation, period of onset of ovarian insufficiency, operation procedure, and pathological diagnosis) were investigated. Of the 835 patients who had ovarian insufficiency, 75 patients (9.0%) underwent ovarian surgery before the onset of ovarian insufficiency. Of those 75 patients, 66 patients (88.0%) underwent cystectomy. For the majority of the 75 patients the surgical indication was the presence of endometriotic cysts (57 patients; 76.0%). Twelve patients (16.0%) underwent multiple surgeries (all bilateral cystectomies). The mean age of the patients at the time of surgery was 27.8±5.5 years-old, and the mean period of onset of ovarian insufficiency was 5.8±3.8 years. In patients with cystectomy, the patient's age at the time of surgery and period of onset of ovarian insufficiency was well-correlated (coefficient of correlation; hemilateral endometriotic cystectomy: -0.64, bilateral endometriotic cystectomy: -0.61, and multiple endimetriotic cystectomy: -0.40). We found that cystectomy of endometriotic cysts is the potential risk factor for ovarian insufficiency after surgery, at times, the onset of ovarian insufficiency long after cystectomy. Therefore, it is important to monitor ovarian reserve for an extended period of time after ovarian surgery. It is particularly important to monitor ovarian reserve long-term for patients who wish to conceive in the future and to suggest a variety of infertility

    About 90% of malignant tumors of the ovary in Scandinavia develop from the germinal epithelium. There are great differences in the incidence rates between countries in the Western world and in Africa and Asia. The WHO classification of ovarian malignancies is generally used. The epithelial tumors comprise the serous, mucinous, endometrioid, clear cell, undifferentiated and mixed true carcinomas. In addition, borderline lesions of especially the serous and mucinous types are of interest when the question of preservation of ovarian function comes into notice. Conservative surgery, which means removal of only the afflicted ovary should be restricted to young women of the childbearing age who want to preserve the possibility of becoming pregnant. However, certain prerequisites must be fulfilled. The tumor must be located to one ovary only (Stage Ia) and must be either a borderline lesion or a Grade 1 true carcinoma of either the serous, mucinous or endometrioid type. There must be no ascites and peritoneal washings must be negative for cancer cells. Germ cell tumors are usually found in young women. Only the dysgerminomas are regularly bilateral in 10-15% of the cases. All other germ cell tumors are rarely bilateral. But both in borderline lesions, Grade 1 true carcinomas, and in germ cell tumors, a biopsy of the normal looking contralateral ovary should always be performed. Endodermal sinus tumors and immature teratomas may well be treated conservatively by surgery, but modern triple chemotherapy (VAC, PVB) must be added. Granulosa theca cell tumors are bilateral in only about 5% of the cases.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2824278

    Ovarian malignant germ cell tumors (OMGCTs) are heterogeneous tumors that are derived from the primitive germ cells of the embryonic gonad. OMGCTs are rare, accounting for about 2.6% of all ovarian malignancies, and typically manifest in adolescence, usually with abdominal pain, a palpable mass, and elevated serum tumor marker levels, which may serve as an adjunct in the initial diagnosis, monitoring during therapy, and posttreatment surveillance. Dysgerminoma, the most common malignant germ cell tumor, usually manifests as a solid mass. Immature teratomas manifest as a solid mass with scattered foci of fat and calcifications. Yolk sac tumors usually manifest as a mixed solid and cystic mass. Capsular rupture or the bright dot sign, a result of increased vascularity and the formation of small vascular aneurysms, may be present. Embryonal carcinomas and polyembryomas rarely manifest in a pure form and are more commonly part of a mixed germ cell tumor. Some OMGCTs have characteristic features that allow a diagnosis to be confidently made, whereas others have nonspecific features, which make them difficult to diagnose. However, imaging features, the patient's age at presentation, and tumor markers may help establish a reasonable differential diagnosis. Malignant ovarian germ cell tumors spread in the same manner as epithelial ovarian neoplasms but are more likely to involve regional lymph nodes. Preoperative imaging may depict local extension, peritoneal disease, and distant metastases. Suspicious areas may be sampled during surgery. Because OMGCTs are almost always unilateral and are chemosensitive, fertility-sparing surgery is the standard of care. PMID:24819795

    We used DNA microarrays to characterize the global gene expression patterns in surface epithelial cancers of the ovary. We identified groups of genes that distinguished the clear cell subtype from other ovarian carcinomas, grade I and II from grade III serous papillary carcinomas, and ovarian from breast carcinomas. Six clear cell carcinomas were distinguished from 36 other ovarian carcinomas (predominantly serous papillary) based on their gene expression patterns. The differences may yield insights into the worse prognosis and therapeutic resistance associated with clear cell carcinomas. A comparison of the gene expression patterns in the ovarian cancers to published data of gene expression in breast cancers revealed a large number of differentially expressed genes. We identified a group of 62 genes that correctly classified all 125 breast and ovarian cancer specimens. Among the best discriminators more highly expressed in the ovarian carcinomas were PAX8 (paired box gene 8), mesothelin, and ephrin-B1 (EFNB1). Although estrogen receptor was expressed in both the ovarian and breast cancers, genes that are coregulated with the estrogen receptor in breast cancers, including GATA-3, LIV-1, and X-box binding protein 1, did not show a similar pattern of coexpression in the ovarian cancers.

    Prostatic adenocarcinoma is the most common cancer in men, but only a handful of cases of prostatic angiosarcoma have been reported in the literature. Prior radiation therapy for prostatic adenocarcinoma has been hypothesized to be a risk factor for angiosarcoma. The increasing practice of prostate cancer screening and the use of radiation therapy for management of prostatic adenocarcinoma will likely lead to more cases of prostatic angiosarcoma. Diagnosis is made by tissue sampling. Optimal management of these aggressive tumors remains to be defined and outcomes are poor with a high 1-year mortality. Primary care physicians and urologists should be aware of this rare entity and refer these patients to specialist centers where they can be managed by a multidisciplinary team. We report a case of angiosarcoma of the prostate gland diagnosed in a male presenting with lower urinary tract symptoms 5 years after brachytherapy for prostate adenocarcinoma. PMID:26889128

    Germ-line DICER1 mutations predispose to a distinctive tumour predisposition syndrome, the DICER1 syndrome, which is associated with a spectrum of rare mainly childhood-onset tumours. In 2014, a case of well-differentiated fetal adenocarcinoma of the lung (WDFA) was reported in a 16-year-old germ-line DICER1 mutation carrier. Here we report our finding of a characteristic somatic DICER1 RNase IIIb c.5127T>A (p.Asp1709Glu) missense mutation within the WDFA, confirmed using laser capture microscopy. The child has a personal history consistent with the DICER1 syndrome: she developed a multinodular goitre at age 14 years and an ovarian Sertoli-Leydig cell tumour at age 16 years, each of which were found to harbour a somatic DICER1 RNase IIIb missense mutation. The identification of two DICER1 "hits" in the WDFA strongly suggests that WDFA is a rare, previously-unrecognised manifestation of DICER1 syndrome. PMID:26886166

    Seromucinous neoplasms are a new category of ovarian epithelial tumor in the revised World Health Organization Classification of Tumours of the Female Reproductive Organs. Borderline variants are well described, but there have been few reports of seromucinous carcinomas. We report the clinicopathologic features in 19 cases of ovarian seromucinous carcinoma in patients aged 16 to 79 years (mean 47). In 16 cases, the neoplasm was unilateral and in 3 cases bilateral. The tumors ranged in size from 1.8 to 18 cm (mean 10.5 cm). The tumors were stage I (n=15), stage II (n=1), and stage III (n=3). The histologic features were highly variable both within and between individual tumors. The majority of neoplasms (12 cases) exhibited a predominant papillary architecture with lesser components of glandular, microglandular, and solid growth. A predominant glandular architecture was present in 6 cases, whereas 1 had a predominantly solid growth. A characteristic feature was an admixture of cell types. Most of the tumors (15 cases) were mainly composed of endocervical-like mucinous cells, whereas in 4 cases there was predominant endometrioid differentiation. Other cell types, present in varying proportions, included hobnail cells, eosinophilic cells, squamous cells, clear cells, and signet-ring cells. An infiltrate of neutrophil polymorphs was a prominent feature in most cases. Most cases also exhibited areas of microglandular architecture with cytoplasmic clearing and intraluminal polymorphs, the features closely resembling cervical microglandular hyperplasia. Areas of stromal hyalinization, adenofibromatous growth, and psammoma bodies were present in a minority of cases. Endometriosis was identified in the same ovary in 10 cases, and in 10 there was a component of seromucinous borderline tumor. Thirteen, 5, and 1 tumor were of grades 1, 2, and 3, respectively (using the FIGO grading system for endometrioid adenocarcinomas of the uterine corpus). A synchronous uterine

    Cdc42 (cell division control protein 42) and Rac1 (Ras-related C3 botulinum toxin substrate 1) are attractive therapeutic targets in ovarian cancer based on established importance in tumor cell migration, adhesion, and invasion. Despite a predicted benefit, targeting GTPases has not yet been translated to clinical practice. We previously established that Cdc42 and constitutively active Rac1b are overexpressed in primary ovarian tumor tissues. Through high-throughput screening and computational shape homology approaches, we identified R-ketorolac as a Cdc42 and Rac1 inhibitor, distinct from the anti-inflammatory, cyclooxygenase inhibitory activity of S-ketorolac. In the present study, we establish R-ketorolac as an allosteric inhibitor of Cdc42 and Rac1. Cell-based assays validate R-ketorolac activity against Cdc42 and Rac1. Studies on immortalized human ovarian adenocarcinoma cells (SKOV3ip) and primary patient-derived ovarian cancer cells show that R-ketorolac is a robust inhibitor of growth factor or serum-dependent Cdc42 and Rac1 activation with a potency and cellular efficacy similar to small-molecule inhibitors of Cdc42 (CID2950007/ML141) and Rac1 (NSC23766). Furthermore, GTPase inhibition by R-ketorolac reduces downstream p21-activated kinases (PAK1/PAK2) effector activation by >80%. Multiple assays of cell behavior using SKOV3ip and primary patient-derived ovarian cancer cells show that R-ketorolac significantly inhibits cell adhesion, migration, and invasion. In summary, we provide evidence for R-ketorolac as a direct inhibitor of Cdc42 and Rac1 that is capable of modulating downstream GTPase-dependent, physiologic responses, which are critical to tumor metastasis. Our findings demonstrate the selective inhibition of Cdc42 and Rac1 GTPases by an FDA-approved drug, racemic ketorolac, that can be used in humans. PMID:26206334

    Mixed adenoneuroendocrine carcinoma (MANEC) is a malignant tumor with adenocarcinoma and neuroendocrine components, with ≥30% of each component required. MANEC of the ampulla is rare. To the best of our knowledge, only 15 cases of MANEC of the ampulla have been reported in the English-language literature. Here, we report two cases of MANEC of the ampulla in two women aged 43 and 60 years, which was confirmed by histology after pancreaticoduodenectomy. These tumors contained neuroendocrine and adenocarcinoma components. The neuroendocrine components were positive for chromogranin A (CgA), synaptophysin (Syn) and CD56 by immunostaining. The adenocarcinoma components were negative for CgA, Syn and CD56. Both cases were T3N0M0 (Stage IIIA). They survived for 15 and 20 mo after surgery, respectively. A brief discussion about the histopathological features, clinical behavior and treatment of MANEC of ampulla, and review of the relevant literature are presented. PMID:25717267

    Borderline ovarian tumours are low malignant potential tumours. They represent 10–15% of all epithelial ovarian malignancies. Patients with this type of tumour are younger at the time of diagnosis than patients with invasive ovarian cancer. Most of them are diagnosed in the early stages and have an excellent prognosis. It has been quite clearly established that the majority of borderline ovarian tumours should be managed with surgery alone. Because a high proportion of women with this malignancy are young and the prognosis is excellent, the preservation of fertility is an important issue in the management of these tumours. In this systemic review of the literature, we have evaluated in-depth oncological safety and reproductive outcomes in women with borderline ovarian tumours treated with fertility-sparing surgery, reviewing the indications, benefits, and disadvantages of each type of conservative surgery, as well as new alternative options to surgery to preserve fertility.

    Ovarian cancer is the leading cause of death from gynecologic malignancies. Reasons for the high mortality rate associated with ovarian cancer include a late diagnosis at which time the cancer has metastasized throughout the peritoneal cavity. Cancer metastasis is facilitated by the remodeling of the extracellular tumor matrix by a family of proteolytic enzymes known as the matrix metalloproteinases (MMPs). There are 23 members in the MMP family, many of which have been reported to be associated with ovarian cancer. In the current paradigm, ovarian tumor cells and the surrounding stromal cells stimulate the synthesis and/or activation of various MMPs to aid in tumor growth, invasion, and eventual metastasis. This review sheds light on the different MMPs in the various types of ovarian cancer and their impact on the progression of this gynecologic malignancy. PMID:25918438

    AIMS: To determine the causes of ovarian granulomatous inflammation and to discuss the differential diagnoses. METHODS: The pathological features of all ovarian granulomas identified by pathology SNOMED coding in Northern Ireland over a 13 year period were reviewed. Case notes of patients were also reviewed. RESULTS: The most common cause of ovarian granuloma was a foreign body reaction to suture material introduced at a previous operative procedure (15 cases). Other causes were Crohn's disease (four cases), previous diathermy (two cases), tuberculosis (two cases), a necrotising reaction following previous surgery (two cases), endometriosis (one case), and bacterial tubo-ovarian abscess (one case). In five cases, no cause was apparent for the granulomatous inflammation. In these, varying numbers of small, well circumscribed cortical granulomas were present. These cases correspond to so-called "idiopathic" cortical granulomas. CONCLUSION: The study confirms the wide range of conditions which can give rise to ovarian granulomatous inflammation.

    Molecularly targeted therapy is relatively new to ovarian cancer despite the unquestionable success with these agents in other solid tumours such as breast and colorectal cancer. Advanced ovarian cancer is chemosensitive and patients can survive several years on treatment. However chemotherapy diminishes in efficacy over time whilst toxicities persist. Newer biological agents that target explicit molecular pathways and lack specific chemotherapy toxicities such as myelosuppression offer the advantage of long-term therapy with a manageable toxicity profile enabling patients to enjoy a good quality of life. In this review we appraise the emerging data on novel targeted therapies in ovarian cancer. We discuss the role of these compounds in the front-line treatment of ovarian cancer and in relapsed disease; and describe how the development of predictive clinical, molecular and imaging biomarkers will define the role of biological agents in the treatment of ovarian cancer.

    We investigated whether there might be excess ovarian cancer mortality among women residing near Spanish industries, according to different categories of industrial groups and toxic substances. An ecologic study was designed to examine ovarian cancer mortality at a municipal level (period 1997-2006). Population exposure to pollution was estimated by means of distance from town to facility. Using Poisson regression models, we assessed the relative risk of dying from ovarian cancer in zones around installations, and analyzed the effect of industrial groups and pollutant substances. Excess ovarian cancer mortality was detected in the vicinity of all sectors combined, and, principally, near refineries, fertilizers plants, glass production, paper production, food/beverage sector, waste treatment plants, pharmaceutical industry and ceramic. Insofar as substances were concerned, statistically significant associations were observed for installations releasing metals and polycyclic aromatic chemicals. These results support that residing near industries could be a risk factor for ovarian cancer mortality. PMID:26046426

    The authors report one case of cavernous hemangioma of the left ovary, which was revealed by ovarian torsion. Such benign tumors of the blood vessels are rare in ovaries during childhood. This hemangioma was observed in a 13-year-old patient, who presented with abdominal and pelvic pain and vomiting. The pelvic mass was noted and sonography revealed a cystic tumor. An annexectomia was realized. Histology showed narcotized ovary cells, with an increased number of vascular channels composed of thin walled vessels, whose wall consisted of an endothelium. This aspect evoked a cavernous hemangioma of the ovary. PMID:14613693

    Mixed adenoneuroendocrine carcinomas (MANECs) are a challenge for the diagnostics and the concept of a histogenetic tumor typing. They are classified into three malignant subgroups: high grade malignant MANECs combine an adenoma or adenocarcinoma with a small cell or large cell neuroendocrine carcinoma, intermediate grade malignant MANECs consist of a neuroendocrine tumor (NET grade 1 or 2), often a globlet cell carcinoid and a poorly differentiated adenocarcinoma or diffuse carcinoma of signet ring cell type. The prototype of a low grade malignant MANEC is the globlet cell carcinoid. Molecular analysis indicates a common clonal origin of the different components in MANECs. The prognosis is determined by the most aggressive tumor component. The pathogenesis of MANECs is apparently a sequence of increasing malignant transformation which leads either from an adenoma/adenocarcinoma to a small or large cell neuroendocrine carcinoma or from a neuroendocrine tumor (NET), often a globlet cell carcinoid to a poorly differentiated adenocarcinoma or a diffuse carcinoma of signet ring cell type.

    Reovirus selectively replicates in and destroys cancer cells with an activated Ras signaling pathway. In this study, we evaluated the feasibility of using reovirus (serotype 3, strain Dearing) as an antihuman colon and ovarian cancer agent. In in vitro studies, reovirus infection in human colon and ovarian cell lines was assessed by cytopathic effect as detected by light microscopy, [(35)S]Methionine labeling of infected cells for viral protein synthesis and progeny virus production by plaque assay. We observed that reovirus efficiently infected all five human colon cancer cell lines (Caco-2, DLD-1, HCT-116, HT-29, and SW48) and four human ovarian cancer cell lines (MDAH2774, PA-1, SKOV3, and SW626) which were tested, but not a normal colon cell line (CCD-18Co) or a normal ovarian cell line (NOV-31). We also observed that the Ras activity in the human colon and ovarian cancer cell lines was elevated compared with that in normal colon and ovarian cell lines. In animal models, intraneoplastic as well as i.v. inoculation of reovirus resulted in significant regression of established s.c. human colon and ovarian tumors implanted at the hind flank. Histological studies revealed that reovirus infection in vivo was restricted to tumor cells, whereas the surrounding normal tissue remained uninfected. Additionally, in an i.p. human ovarian cancer xenograft model, inhibition of ascites tumor formation and the survival of animals treated with live reovirus was significantly greater than of control mice treated with UV-inactivated reovirus. Reovirus infection in ex vivo primary human ovarian tumor surgical samples was also confirmed, further demonstrating the potential of reovirus therapy. These results suggest that reovirus holds promise as a novel agent for human colon and ovarian cancer therapy. PMID:11912142

    The incidence of ovarian tumors diagnosed during pregnancy is between 0.3 and 5.4% (LE2). The most common ovarian tumors diagnosed during pregnancy are functional cysts diagnosed incidentally during the first trimester ultrasound (LE2) and spontaneous regression is often observed. Dermoid cysts and cystadenoma are the most frequent organic benign ovarian tumors diagnosed during pregnancy (LE2). The main complication of presumed benign ovarian tumor (PBOT) during pregnancy is adnexal torsion and is estimated at around 8% (LE2), especially at the end of the first trimester and during the second trimester (LE4). Tumor markers are not reliable during pregnancy to assess the risk of malignancy of ovarian tumor (LE2). Ultrasound remains the gold standard for characterizing an ovarian tumor during pregnancy (LE3), but with a lower specificity for the diagnosis of malignancy. Pelvic MRI is accurate in the diagnosis of ovarian tumors during pregnancy and brings additional information to ultrasound (LE4). Ultrasound-guided aspiration of ovarian tumors is not recommended during pregnancy (grade C). Expectation is recommended in cases of PBOT during pregnancy, which does not enlarge (grade C). Whatever the gestational age, surgery is recommended in patients with symptoms suggesting an adnexal torsion (grade C). Laparoscopy is possible during the first and second trimester of pregnancy for the management of symptomatic PBOT (LE3). The risk of miscarriage following surgery (laparoscopy and laparotomy) for ovarian tumor during pregnancy is estimated at 2.8% (LE3). The route of delivery should not be modified by the ovarian tumour, except in case of praevia cyst requiring a cesarean section, a complication or suspicion of malignancy (grade C). Surgical treatment of PBOT may be performed during a cesarean section indicated for another reason. The risk of torsion is increased during the postpartum period (LE4). PMID:24210242

    Massive ovarian edema is a rare tumor-like condition found in young women resulting from accumulation of fluid mostly due to partial or intermittent torsion of the ovary or secondary, to a preexisting ovarian lesion. We report a case of a 13-year-old girl presenting with an ovarian mass measuring 16 cm. CA-12-5 levels were slightly elevated. Concerns regarding underlying malignancy led to salpingo-oophorectomy. Pathological evaluation revealed a massive ovarian edema and multiple thromboses of ovarian veins. Differentiating massive ovarian edema from malignant ovarian tumor is crucial to prevent patients from undergoing unnecessary surgery. PMID:23649810

    Background There is still no reliable biomarker for the diagnosis of pancreatic adenocarcinoma. Carbohydrate antigen 19–9 (CA 19–9) is a tumor marker only recommended for pancreatic adenocarcinoma follow-up. One of the clinical problems lies in distinguishing between this cancer and other benign pancreatic diseases such as chronic pancreatitis. In this study we will assess the value of panels of serum molecules related to pancreatic cancer physiopathology to determine whether alone or in combination could help to discriminate between these two pathologies. Methods CA 19–9, carcinoembryonic antigen (CEA), C-reactive protein, albumin, insulin growth factor-1 (IGF-1) and IGF binding protein-3 were measured using routine clinical analyzers in a cohort of 47 pancreatic adenocarcinoma, 20 chronic pancreatitis and 15 healthy controls. Results The combination of CA 19–9, IGF-1 and albumin resulted in a combined area under the curve (AUC) of 0.959 with 93.6% sensitivity and 95% specificity, much higher than CA 19–9 alone. An algorithm was defined to classify the patients as chronic pancreatitis or pancreatic cancer with the above specificity and sensitivity. In an independent validation group of 20 pancreatic adenocarcinoma and 13 chronic pancreatitis patients, the combination of the four molecules classified correctly all pancreatic adenocarcinoma and 12 out of 13 chronic pancreatitis patients. Conclusions Although this panel of markers should be validated in larger cohorts, the high sensitivity and specificity values and the convenience to measure these parameters in clinical laboratories shows great promise for improving pancreatic adenocarcinoma diagnosis.

    Colorectal adenocarcinoma is the second cause of cancer-related deaths in the United States. The occurrence of squamous cell carcinoma in the colorectum is extremely unusual. Malignant transformation from mature cystic teratoma of the ovary is a rare event. The most common transformation is squamous cell carcinoma, followed by adenocarcinoma. It occurs more often in elderly patients, who usually present with advance disease. We report two unusual cases of postmenopausal women diagnosed with squamous cell carcinoma in colon biopsies. After surgical resections, the carcinoma was proven to be the result of malignant transformation of ovarian mature cystic teratomas. Since squamous cell carcinoma of the colorectum is extremely rare, the presence of squamous cell carcinoma in a colonic biopsy in a female patient should alert the clinicians to other possible primary sites, as seen in these cases.

    Mucins are heavily glycosylated proteins overexpressed and associated with truncated or sialylated glycans upon malignant transformation. We previously identified a panel of four glyco-mucin profiles (MUC16/Tn, MUC16/STn, MUC1/Tn, and MUC1/STn) with 100 % specificity and 100 % positive predictive value for detection of borderline/malignant serous tumors of the ovary, using proximity ligation assay (PLA). In the present work, using the same method, we studied other mucin glycosylation profiles that might add relevant information for diagnostic purposes. We used PLA probes to MUC16, MUC1, sialyl Lewis(a) (SLe(a)), and sialyl Lewis(x) (SLe(x)) to study a series of 39 ovarian serous tumors (14 adenocarcinomas, 10 borderline ovarian tumors (BOTs), and 15 cystadenomas). Our results demonstrated that, in adenocarcinomas and BOTs, the major carriers of SLe(a) and SLe(x) are MUC16 and/or MUC1 (100 and 92 % for SLe(a) and 64 and 70 % for SLe(x), respectively). In cystadenomas, SLe(a) and SLe(x) are mainly carried by unidentified proteins (85 and 78 %, respectively). Our study identified, for the first time, the major protein carriers of SLe(a) and SLe(x) in ovarian adenocarcinomas and BOTs, MUC1 and MUC16, and also that distinct unidentified carriers are involved in cystadenomas. These results emphasize the relevance of multiple biomarker recognition provided by multiplex assays, such as PLA, to enhance sensitivity and specificity of serum and tissue assays. PMID:27003157

    Metastasis of ovarian cancer to the breast (MOCB) is a rare event. Clinical presentations of MOCB vary and surgery is the mainstay of treatment. The current study presents two cases of MOCB in women with recurrent ovarian cancer first diagnosed in April 2011 and October 2013, respectively. The patients presented to the clinic with a localized, palpable, painful mass in the upper outer quadrant of the right breast and a centrally localized, palpable, painful mass of the left breast, respectively. Breast sonography and mammography showed a singular, round, homogenous tumor with irregular borders in each case. An ipsilateral enlarged axillary node was palpable in one case. Tumor biopsy revealed an undifferentiated adenocarcinoma of unknown origin in one case and a moderately-differentiated adenocarcinoma suspected to be breast cancer in the other case. Tumor cells were positive for estrogen receptor and paired box 8, and negative for GATA binding protein 3 in the two cases. Palliative mastectomy was performed in one case and lumpectomy with ipsilateral axillary sentinel node biopsy in the other case, and the final histology revealed MOCB in each. The post-operative course of the disease was uneventful and the patients continued with their ovarian cancer-specific chemotherapy. One patient succumbed to disease progression 2 months after breast surgery. The other patient remains alive and is currently undergoing systemic chemotherapy. The current study also presents a review of 110 cases of MOCB identified in a literature search of Pubmed. Data from these studies, including the clinical and histological characteristics of MOCB, and the clinical management and prognosis are discussed. Overall, MOCB is rare, with distinct clinical and histological features. The disease is usually treated with local surgical excision or mastectomy and has a poor prognosis. PMID:27313731

    Ovarian cancer relapse is often characterized by metastatic spread throughout the peritoneal cavity with tumors attached to multiple organs. In this study, interaction of ovarian cancer cells with the peritoneal tumor microenvironment was evaluated in a xenograft model based on intraperitoneal injection of fluorescent SKOV3.ip1 ovarian cancer cells. Intra-vital microscopy of mixed GFP-red fluorescent protein (RFP) cell populations injected into the peritoneum demonstrated that cancer cells aggregate and attach as mixed spheroids, emphasizing the importance of homotypic adhesion in tumor formation. Electron microscopy provided high resolution structural information about local attachment sites. Experimental measurements from the mouse model were used to build a three-dimensional cellular Potts ovarian tumor model (OvTM) that examines ovarian cancer cell attachment, chemotaxis, growth, and vascularization. OvTM simulations provide insight into the relative influence of cancer cell–cell adhesion, oxygen availability, and local architecture on tumor growth and morphology. Notably, tumors on the mesentery, omentum, or spleen readily invade the “open” architecture, while tumors attached to the gut encounter barriers that restrict invasion and instead rapidly expand into the peritoneal space. Simulations suggest that rapid neovascularization of SKOV3.ip1 tumors is triggered by constitutive release of angiogenic factors in the absence of hypoxia. This research highlights the importance of cellular adhesion and tumor microenvironment in the seeding of secondary ovarian tumors on diverse organs within the peritoneal cavity. Results of the OvTM simulations indicate that invasion is strongly influenced by features underlying the mesothelial lining at different sites, but is also affected by local production of chemotactic factors. The integrated in vivo mouse model and computer simulations provide a unique platform for evaluating targeted therapies for ovarian cancer

    Pancreatic cancer is a devastating disease. At time of diagnosis the disease is usually advanced and only a minority of patients are eligible for surgical resection. The overall 5-year survival is 6%. However, survival of patients with early stage pancreatic cancer is significantly better. To improve the prognosis of patients with pancreatic cancer, it is essential to diagnose and treat pancreatic cancer in the earliest stage. Prevention of pancreatic cancer by treating noninvasive precursor lesions just before they invade tissues can potentially lead to even better outcomes. Pancreatic carcinogenesis results from a stepwise progression in which accumulating genetic alterations drive neoplastic progression in well-defined precursor lesions, ultimately giving rise to an invasive adenocarcinoma. A thorough understanding of the genetic changes that drive pancreatic carcinogenesis can lead to identification of biomarkers for early detection and targets for therapy. Recent next-generation sequencing (NGS) studies have shed new light on our understanding of the natural history of pancreatic cancer and the precursor lesions that give rise to these cancers. Importantly, there is a significant window of opportunity for early detection and treatment between the first genetic alteration in a cell in the pancreas and development of full-blown pancreatic cancer. The current views on the pathology and genetics of pancreatic carcinogenesis that evolved from studies of pancreatic cancer and its precursor lesions are discussed in this review. PMID:26261723

    Endometriosis generally occurs in the ovary. Intestinal endometriosis is rare. About 1 % of all endometriosis cases become malignant. Malignant transformation of small intestinal endometriosis is very rare. A 55-year-old woman who underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy and omentectomy for endometriosis 7 years ago presented to her primary care doctor with melena. A tumor was detected in the right lower abdomen by ultrasonography. The doctor referred her to our hospital. Computed tomography demonstrated a lobulated tumor ventral to the right common iliac vessels. Magnetic resonance imaging demonstrated that the tumor had heterogeneous intensity on T2-weighted images. Several small cysts with high intensity were observed caudal to the tumor on T2-weighted images. We performed partial small intestinal resection for the lesion. The tumor was diagnosed as endometrioid adenocarcinoma of the small intestine. She has been relapse-free for 5 years after surgery. Only three cases of malignant transformation of small intestinal endometriosis have been reported previously. It is very rare for long-term survival to be obtained with surgery alone, as in our case. This case report highlights the imaging findings for malignant transformation of intestinal endometriosis. PMID:27624553

    Uterine cervical adenocarcinoma (ADC) has been increasing in its prevalence world widely despite the decrease of squamous cell carcinoma (SCC). It comprises nearly 20-25% of the all cervical malignancy in developed countries. The worse biological behavior had been reported in patients with intermediate- and high risk factors after surgery, and in advanced stage over Ⅲ, radiotherapy (RT) alone and concurrent chemo-radiotherapy (CCRT) with cisplatin was not always effective. As for chemotherapy (CT), the induction CT has not established, as well. Further molecular targeted therapy (MTT) has been studied. The targets of oncogenic driver mutations were vascular endothelial growth factor (VEGF) in SCC, or tyrosine kinase (TK) of endothelial growth factor receptor 2 (EGFR2, Her2/neu)-Ras-MAPK-ERK pathway. Bevacizumab (Bev, anti-VEGF monoclonal antibody) is considered as one of key agent with paclitaxel and carboplatin in SCC, but not for ADC. This article focuses on up-to-date knowledge of biology and possible specific therapeutic directions to explore in the management of cervical ADC. PMID:27198186

    Hepatoid adenocarcinoma (HAC) is a rare neoplasm with aberrant hepatocellular differentiation. HAC occurs in extrahepatic organs such as the gastrointestinal tract, testes, ovaries, and lungs and frequently produces alpha-fetoprotein. A 69-year-old patient was diagnosed clinically with T2aN0M0, stage IB, non-small cell lung carcinoma. Because the tumor showed tight adhesion to the chest wall, we performed left upper lobectomy, combined resection of the 3rd and 4th ribs, and lymph node dissection. Pathological examination confirmed the diagnosis of HAC of the lung (pathological T2aN0M0, stage IB), and four courses of cisplatin and gemcitabine were administered as adjuvant chemotherapy. Genetic analysis of the epidermal growth factor receptor showed wild type. Preoperative serum alpha-fetoprotein level, a useful marker of disease progression, was elevated to 4497 ng/ml, decreasing within the normal range by about 3 months postoperatively. The patient remains alive without recurrence as of 51 months after surgery. PMID:26943677

    Systemic treatment of metastatic pancreatic adenocarcinoma achieves only modest benefits, with evidence indicating a survival advantage with 5-fluorouracil (5-FU) over best supportive care alone, and further advantage of single-agent gemcitabine over 5-FU. There are very few regimens better than single-agent gemcitabine despite multiple trials of cytotoxic and targeted agents. The addition of a platinum agent has improved response rate but not survival. The addition of erlotinib has improved survival but only by a small margin. The use of gemcitabine in multidrug regimens containing one or more of: a platinum agent; fluoropyrimidine; anthracycline; and taxane has demonstrated advantages in response rate, progression-free survival and, in one randomized study, overall survival. After gemcitabine failure, second-line therapy with oxaliplatin and 5-FU provides a further survival advantage. Further advances depend upon the current and future clinical trials investigating enhanced delivery of current agents, new agents and novel modalities, improved supportive care, and treatment more tailored to the individual patient and tumour.

    With 5-year survival rates remaining constant at 6% and rising incidences associated with an epidemic in obesity and metabolic syndrome, pancreatic ductal adenocarcinoma (PDAC) is on track to become the second most common cause of cancer-related deaths by 2030. The high mortality rate of PDAC stems primarily from the lack of early diagnosis and ineffective treatment for advanced tumors. During the past decade, the comprehensive atlas of genomic alterations, the prominence of specific pathways, the preclinical validation of such emerging targets, sophisticated preclinical model systems, and the molecular classification of PDAC into specific disease subtypes have all converged to illuminate drug discovery programs with clearer clinical path hypotheses. A deeper understanding of cancer cell biology, particularly altered cancer cell metabolism and impaired DNA repair processes, is providing novel therapeutic strategies that show strong preclinical activity. Elucidation of tumor biology principles, most notably a deeper understanding of the complexity of immune regulation in the tumor microenvironment, has provided an exciting framework to reawaken the immune system to attack PDAC cancer cells. While the long road of translation lies ahead, the path to meaningful clinical progress has never been clearer to improve PDAC patient survival. PMID:26883357

    Charts of 36 patients with clinical stage II endometrial adenocarcinoma over ten years were reviewed. All were staged before any treatment, in accordance with International Federation of Gynecology and Obstetrics (FIGO) guidelines. Although details of treatment varied, two main protocols were used. Fourteen patients were treated with the standard protocol involving external whole-pelvis radiation, followed by intracavitary cesium and then hysterectomy. In 1981, a modified protocol was introduced, which called for a hysterectomy immediately following intrauterine and vaginal cesium. External radiation therapy was given only to those patients found to have deep myometrial invasion or cervical involvement. Of 14 patients treated by this protocol, seven had no surgical indication for postoperative external radiation. There was no increase in recurrence in these patients, and the five-year survival rate was 76% for patients treated with the modified protocol compared with 65% for those who had standard therapy. Morbidity related to external radiation therapy occurred in two patients with the standard protocol and one patient who received pelvic radiation on the modified protocol.

    Uterine cervical adenocarcinoma (ADC) has been increasing in its prevalence world widely despite the decrease of squamous cell carcinoma (SCC). It comprises nearly 20-25% of the all cervical malignancy in developed countries. The worse biological behavior had been reported in patients with intermediate- and high risk factors after surgery, and in advanced stage over Ⅲ, radiotherapy (RT) alone and concurrent chemo-radiotherapy (CCRT) with cisplatin was not always effective. As for chemotherapy (CT), the induction CT has not established, as well. Further molecular targeted therapy (MTT) has been studied. The targets of oncogenic driver mutations were vascular endothelial growth factor (VEGF) in SCC, or tyrosine kinase (TK) of endothelial growth factor receptor 2 (EGFR2, Her2/neu)-Ras-MAPK-ERK pathway. Bevacizumab (Bev, anti-VEGF monoclonal antibody) is considered as one of key agent with paclitaxel and carboplatin in SCC, but not for ADC. This article focuses on up-to-date knowledge of biology and possible specific therapeutic directions to explore in the management of cervical ADC. PMID:27198186

    Pancreatic ductal adenocarcinoma (PDAC) accounts for over 90% of all pancreatic cancer. Nanoparticles (NPs) offer new opportunities for image-guided therapy owing to the unique physicochemical properties of the nanoscale effect and the multifunctional capabilities of NPs. However, major obstacles exist for NP-mediated cancer theranostics, especially in PDAC. The hypovascular nature of PDAC may impede the deposition of NPs into the tumor after systemic administration, and most NPs localize predominantly in the mononuclear phagocytic system, leading to a relatively poor tumor-to-surrounding-organ uptake ratio. Image guidance combined with minimally invasive interventional procedures may help circumvent these barriers to poor drug delivery of NPs in PDAC. Interventional treatments allow regional drug delivery, targeted vascular embolization, direct tumor ablation, and the possibility of disrupting the stromal barrier of PDAC. Interventional treatments also have potentially fewer complications, faster recovery, and lower cost compared with conventional therapies. This work is an overview of current image-guided interventional cancer nanotheranostics with specific attention given to their applications for the management of PDAC. PMID:27375787

    Gastric cancer is a leading cause of cancer deaths, but analysis of its molecular and clinical characteristics has been complicated by histological and aetiological heterogeneity. Here we describe a comprehensive molecular evaluation of 295 primary gastric adenocarcinomas as part of The Cancer Genome Atlas (TCGA) project. We propose a molecular classification dividing gastric cancer into four subtypes: tumours positive for Epstein–Barr virus, which display recurrent PIK3CA mutations, extreme DNA hypermethylation, and amplification of JAK2, CD274 (also known as PD-L1) and PDCD1LG2 (also knownasPD-L2); microsatellite unstable tumours, which show elevated mutation rates, including mutations of genes encoding targetable oncogenic signalling proteins; genomically stable tumours, which are enriched for the diffuse histological variant and mutations of RHOA or fusions involving RHO-family GTPase-activating proteins; and tumours with chromosomal instability, which show marked aneuploidy and focal amplification of receptor tyrosine kinases. Identification of these subtypes provides a roadmap for patient stratification and trials of targeted therapies. PMID:25079317

    The incidence of esophageal adenocarcinoma (EAC) has increased rapidly during the past 4 decades in many Western populations, including North America and Europe. The established etiological factors for EAC include gastroesophageal reflux and obesity, Helicobacter pylori infection, tobacco smoking, and consumption of fruit and vegetables. There is a marked male predominance of EAC with a male-to-female ratio in incidence of up to 9:1. This review evaluates the available literature on the reasons for the male predominance, particularly an update on epidemiologic evidence from human studies during the past decade. The striking sex difference does not seem to be explained by established risk factors, given that the prevalence of the etiological factors and the strengths of associations between these factors and EAC risk are similar between the sexes. Sex hormonal factors may play a role in the development of EAC; estrogenic exposures may prevent such development, whereas androgens might increase the risk of EAC. However, continuing research efforts are still needed to fully understand the reasons for the male predominance of EAC. PMID:26484704

    Ovarian stimulation in the treatment of infertility is far from physiological because patients and their ovaries are exposed to high concentrations of gonadotropins. Many studies have focused on the two most common side-effects of ovarian stimulation--ie, hyperstimulation and multiple pregnancy. We describe 12 patients in whom granulosa-cell tumour was discovered after ovarian stimulation treatment with clomiphene citrate and/or gonadotropins. Although we cannot prove a causal link between the tumour and the medication, investigations in animals have shown a relation between gonadotropin exposition and the development of granulosa-cell tumours. The possible relation of ovarian stimulation and granulosa-cell tumours in human beings has not been published before. We postulate three explanations for this finding; first, the granulosa-cell tumour is present in the ovary, waiting for a hormonal trigger; second, increased follicle stimulating hormone concentrations are oncogenic to granulosa cell; and third, the onset of the granulosa-cell tumour during ovarian stimulation is coincidental. We recommend that ovarian stimulation is done only if there is a valid indication after proper assessment of the ovaries, and that women who have had ovarian stimulation are followed for longer than at present.

    Epidemiological evidence regarding the association between carbohydrate intake, glycaemic load (GL) and glycaemic index (GI) and risk of ovarian cancer has been mixed. Little is known about their impact on ovarian cancer risk in African-American women. Associations between carbohydrate quantity and quality and ovarian cancer risk were investigated among 406 cases and 609 controls using data from the African American Cancer Epidemiology Study (AACES). AACES is an ongoing population-based case-control study of ovarian cancer in African-Americans in the USA. Cases were identified through rapid case ascertainment and age- and site-matched controls were identified by random-digit dialling. Dietary information over the year preceding diagnosis or the reference date was obtained using a FFQ. Multivariable logistic regression models were used to estimate odds ratios and 95% CI adjusted for covariates. The OR comparing the highest quartile of total carbohydrate intake and total sugar intake v. the lowest quartile were 1·57 (95% CI 1·08, 2·28; P trend=0·03) and 1·61 (95% CI 1·12, 2·30; P trend<0·01), respectively. A suggestion of an inverse association was found for fibre intake. Higher GL was positively associated with the risk of ovarian cancer (OR 1·18 for each 10 units/4184 kJ (1000 kcal); 95% CI 1·04, 1·33). No associations were observed for starch or GI. Our findings suggest that high intake of total sugars and GL are associated with greater risk of ovarian cancer in African-American women. PMID:26669283

    Hepatoid adenocarcinoma is a rare extrahepatic tumor, which shows morphological and immunohistochemical similarities to hepatocellular carcinoma (HCC). Hence, hepatoid adenocarcinoma can cause diagnostic confusion with HCC. Arginase-1 immunostain has been recently shown to be an excellent marker of normal hepatocytes and is a sensitive and specific marker for HCC. However, the expression of Arginase-1 in hepatoid adenocarcinoma has not been evaluated in detail. Eight cases of hepatoid adenocarcinoma were immunostained with Arginase-1, Hepar-1, Glypican-3, CK7, CK20, CK19, polyclonal carcinoembryonic antigen, ɑ-fetoprotein, CDX2, and TTF-1. Albumin in situ hybridization was performed in 4 cases. All 8 cases were positive for Hepar-1. Arginase-1 was positive in 5 (62.5%) of 8 cases; 2 of these cases showed diffuse staining, while 3 showed patchy staining. Glypican-3, CK7 and ɑ-fetoprotein were each positive in 4 (50%) of 8 cases. CK19 was positive in 3 (37.5%) of 8 cases. polyclonal carcinoembryonic antigen showed canalicular staining in 3 (37.5%) of 8 cases and albumin in situ hybridization was positive in 3 (75%) of 4 cases. CDX2 was positive in 2 (25%) of 8 cases, both arising from the stomach. CK20 was positive in 1 (12.5%) of 8 case while TTF-1 was negative in all cases. Hepatoid adenocarcinoma has a similar immunostaining profile as HCC. Arginase-1 expression is common (62.5%) in hepatoid adenocarcinoma and hence it is not useful in distinguishing HCC from hepatoid adenocarcinoma. PMID:27137985

    2015-01-01

    As a result of technological advances during the past two decades, surgeons now use minimally invasive surgery (MIS) approaches to pancreatic resection more frequently, yet the role of these approaches for pancreatic ductal adenocarcinoma resections remains uncertain, given the aggressive nature of this malignancy. Although there are no controlled trials comparing MIS technique to open surgical technique, laparoscopic distal pancreatectomy for pancreatic adenocarcinoma is performed with increasing frequency. Data from retrospective studies suggest that perioperative complication profiles between open and laparoscopic distal pancreatectomy are similar, with perhaps lower blood loss and fewer wound infections in the MIS group. Concerning oncologic outcomes, there appear to be no differences in the rate of achieving negative margins or in the number of lymph nodes (LNs) resected when compared to open surgery. There are limited recurrence and survival data on laparoscopic compared to open distal pancreatectomy for pancreatic adenocarcinoma, but in the few studies that assess long term outcomes, recurrence rates and survival outcomes appear similar. Recent studies show that though laparoscopic distal pancreatectomy entails a greater operative cost, the associated shorter length of hospital stay leads to decreased overall cost compared to open procedures. Multiple new technologies are emerging to improve resection of pancreatic cancer. Robotic pancreatectomy is feasible, but there are limited data on robotic resection of pancreatic adenocarcinoma, and outcomes appear similar to laparoscopic approaches. Additionally fluorescence-guided surgery represents a new technology on the horizon that could improve oncologic outcomes after resection of pancreatic adenocarcinoma, though published data thus far are limited to animal models. Overall, MIS distal pancreatectomy appears to be a safe and reasonable approach to treating selected patients with pancreatic ductal

    There are 5 major histotypes of ovarian carcinomas. Diagnostic typing criteria have evolved over time, and past cohorts may be misclassified by current standards. Our objective was to reclassify the recently assembled Canadian Ovarian Experimental Unified Resource and the Alberta Ovarian Tumor Type cohorts using immunohistochemical (IHC) biomarkers and to develop an IHC algorithm for ovarian carcinoma histotyping. A total of 1626 ovarian carcinoma samples from the Canadian Ovarian Experimental Unified Resource and the Alberta Ovarian Tumor Type were subjected to a reclassification by comparing the original with the predicted histotype. Histotype prediction was derived from a nominal logistic regression modeling using a previously reclassified cohort (N=784) with the binary input of 8 IHC markers. Cases with discordant original or predicted histotypes were subjected to arbitration. After reclassification, 1762 cases from all cohorts were subjected to prediction models (χ2 Automatic Interaction Detection, recursive partitioning, and nominal logistic regression) with a variable IHC marker input. The histologic type was confirmed in 1521/1626 (93.5%) cases of the Canadian Ovarian Experimental Unified Resource and the Alberta Ovarian Tumor Type cohorts. The highest misclassification occurred in the endometrioid type, where most of the changes involved reclassification from endometrioid to high-grade serous carcinoma, which was additionally supported by mutational data and outcome. Using the reclassified histotype as the endpoint, a 4-marker prediction model correctly classified 88%, a 6-marker 91%, and an 8-marker 93% of the 1762 cases. This study provides statistically validated, inexpensive IHC algorithms, which have versatile applications in research, clinical practice, and clinical trials. PMID:26974996

    The mechanism by which neuropilin-1 (NRP-1) induces malignancy in Epithelial Ovarian Cancer (EOC) is still unknown. This study is the first to demonstrate the relationship between NRP-1 expression and EMT markers vimentin, N-cadherin, E-cadherin and Slug. We used tissue microarrays containing the three main subtypes of EOC tumors: serous, mucinous cystadenocarcinoma and endometrioid adenocarcinoma and representative cases retrieved from our pathology archives. Immunohistochemistry was performed to detect the expression levels and location of NRP-1 and the aforementioned EMT proteins. NRP-1 was mainly expressed on cancer cells but not in normal ovarian surface epithelium (OSE). The Immunoreactive Scoring (IRS) values revealed that the expression of NRP-1, Slug and E-cadherin in the malignant subtypes of ovarian tissues was significantly higher (5.18 ± 0.64, 4.84 ± 0.7, 4.98 ± 0.68, respectively) than their expression in the normal and benign tissues (1.04 ± 0.29, 0.84 ± 0.68, 1.71 ± 0.66, respectively), with no significant differences among the studied subtypes. Vimentin was expressed in the cancer cell component of 43% of tumors and it was exclusively localized in the stroma of all mucinous tumors. The Spearman's rho value indicated that NRP-1 is positively related to the EMT markers E-cadherin and Slug. This notion might indicate that NRP-1 is a partner in the EMT process in EOC tumors.

As the variable etiology and presentation of POI complicate its management, a standard regimen for treatment remains to be established. However, emerging research has provided new insight on current mainstays of treatment as well as novel management approaches and therapeutic interventions. Recent findings Recent clinical trials in women with POI indicate that the widely-used regimen of transdermal estradiol and medroxyprogesterone acetate restores bone mineral density (BMD) to a level equal to women with normal ovarian function. Further research verifies that compounded bioidentical hormones and androgen supplementation are inadequate in treating POI and lowering risk for long-term sequelae. Additionally, assessing changes in bone turnover markers may be useful for monitoring BMD. Alternative therapies such as acupuncture, DHEA, and buproprion may be effective in treating the effects of estrogen deficiency at some level, but require further investigation. Summary Recent updates show promise in improving management methods and reducing risk of long-term sequelae. Additional research that expands upon the most current literature is critical in order to achieve an evidence-based standard of best practice. PMID:26512773

    The propensity of ovarian cancer to recur--even after initial chemotherapeutic responses--is a problem that has been given a great deal of attention during the past year in the literature dealing with the treatment of ovarian cancer. Most of the articles address techniques to improve the percent of initial and secondary treatment responses. Several studies have described cytoreductive techniques to decrease the remaining tumor size for improved chemotherapeutic response. Cross-resistance between platinum analogues has been reconfirmed. However, improved secondary responses were seen when repeat treatment with platinum agents were preceded by a longer interval from initial platinum agent therapy. Radiation therapy has been shown to offer little solution to recurrent disease except possibly in a select group of patients with microscopic disease at second-look laparotomy. Reports on the use of carboplatin continue to demonstrate good initial responses, with decreased toxicity compared with cisplatin. Granisetron has been shown to significantly decrease the nausea and vomiting caused by emetogenic chemotherapy like cisplatin. PMID:1543823

    The key insight that sparked Darwin's theory of descent with modification was that he compared and contrasted differences between living and extinct species across time and space. He likely arrived on this theory in large part through his culinary experiences, set against the background of the rugged Patagonian landscape of Southern Argentina. We feel that further integration of research into gastric and esophageal adenocarcinoma may benefit both fields and similarly lead to a coherent understanding of cancer progression in the upper gastrointestinal tract across time and space. Although the environmental trigger differs between carcinogenesis of the stomach and distal esophagus, there remain many important lessons to be learned from comparing precursor stages, such as intestinal metaplasia, across anatomic borders. This analysis will absolutely require detailed sampling within and between these related species, but most importantly we need higher resolution clinical phenotyping to relate genomic differences to drivers of morphologic evolution. In the end, this may provide us with a new phylogeny showing key differences between esophageal and gastric adenocarcinoma. PMID:27573764

    We define ovarian retention pathology as the complications (cystic, degenerative, adhesions, endometriosis, pain, etc.) attributed to ovaries deliberately retained at the time of hysterectomy. We established a protocol for laparoscopy in these women. During 14 laparoscopic procedures for ovarian retention pathology, only one intraoperative complication occurred, a small bowel injury requiring minilaparotomy. One woman required repeat surgery for ovarian remnant syndrome. Published experience with laparotomy suggests that significant injuries to or resections of bowel, bladder, or ureters can occur, but the limited experience with laparoscopic surgery has not shown significant complications.

    With about 22,000 new cases estimated in 2012 in the US and 15,500 related deaths, ovarian cancer is a heterogeneous and aggressive disease. Even though most of patients are sensitive to chemotherapy treatment following surgery, recurring disease is almost always lethal, and only about 30% of the women affected will be cured. Thanks to a better understanding of the molecular mechanisms underlying ovarian cancer malignancy, new therapeutic options with molecular-targeted agents have become available. This review discusses the rationale behind molecular-targeted therapies and examines how newly identified molecular targets may enhance personalized therapies for ovarian cancer patients.

    The authors documented by means of light and transmission electron microscopy that the ovaries of women with premature ovarian failure (POF) displayed dense connective tissue and rare corpora albicantia. Eight of the ten studied cases did not present ovarian follicles; in two cases, it was verified the presence of ovarian follicles, atypical primordial follicles and in one case, a corpus luteum was identified (after stimulation with exogenous gonadotrophin). Regarding the ultrastructural analysis, it was noted that the fibroblasts were united one to each other by cellular prolongations that formed a woof, constituting a cellular syncicius. PMID:7610321

    Recent advances in our understanding of the mechanisms underlying the impact of cytotoxic drugs on the ovary have opened up new directions for the protection of the ovary from chemotherapy-induced damage. These advances have spurred the investigation of pharmacological agents to prevent ovarian damage at the time of treatment. Prevention of ovarian damage and follicle loss would provide significant advantages over existing fertility preservation techniques. This manuscript reviews new methods for the prevention of chemotherapy-induced ovarian damage, including agents that act on the PI3K/PTEN/Akt follicle activation pathway, apoptotic pathways, the vascular system, and other potential methods of reducing chemotherapy-induced ovotoxicity.

    There has been reported increased incidence of ovarian tuberculosis in the tropics since the advent of HIV/AIDS disease. We report a case of bilateral ovarian tuberculosis associated with a single right kidney of uncertain origin in an immunocompetent 15-year-old generally healthy-looking girl. Abdominopelvic scan was equivocal about the diagnosis of the lesion as it failed to differentiate it from malignancy. Tuberculin and histopathology were necessary to confirm the diagnosis of ovarian tuberculosis. Antituberculous medical therapy successfully resolved the disease. PMID:26168758

    Olaparib, an oral poly(ADP-ribose) polymerase (PARP) inhibitor, is the first FDA-approved drug in its class for patients with ovarian cancer, specifically in a subset of patients with BRCA mutations and prior chemotherapy treatments. PARP inhibitors have had other implications in different solid tumor types including breast, gastric and pancreatic malignancies. In light of the recent FDA approval of olaparib for the treatment of ovarian cancer, this article aims to outline the mechanisms and implications of the drug. With a favorable adverse event profile and improved outcomes, including progression-free survival, olaparib has demonstrated augmentation to therapeutic options in the treatment of ovarian cancer.

    Hereditary breast and ovarian cancer (HBOC) syndrome and Lynch syndrome (LS) are associated with increased risk of developing ovarian carcinoma. Patients with HBOC have a lifetime risk of up to 50% of developing high-grade serous carcinoma of tube or ovary; patients with LS have a 10% lifetime risk of developing endometrioid or clear cell carcinoma of the ovary. Testing all patients with tubo-ovarian high-grade serous carcinoma for mutations associated with HBOC syndrome, and all patients presenting with endometrioid or clear cell carcinoma of the ovary for mutations associated with LS can identify patients with undiagnosed underlying hereditary cancer susceptibility syndromes.

    We have established an ovarian cancer cell line (CABA I) from ascitic fluid obtained from a patient with papillary adenocarcinoma of the ovary prior to drug treatment. The epithelial origin of the cell line was confirmed by morphology and by immunofluorescence analysis using anticytokeratin antibodies. Ultrastructural analysis revealed a very irregular membrane surface and a clear cytoplasm rich in electron-lucent vesicles. CABA I cells grow rapidly in culture (doubling time 18 h) in an anchorage-independent manner. Exogenously added beta-estradiol and epidermal growth factor (EGF) treatments did not influence cell growth rate. FACS analysis to determine the phenotypic profile of tumor-associated antigen, membrane receptor, and adhesion molecule expression indicated that the cell line was positive for different members of the c-erbB family, for alpha 6 and beta 1 integrin receptors, and intensively positive for HLA class I antigens and the folate receptor. Molecular characterization revealed no mutations for c-myc and c-k-ras genes, but did detect an exon 5 mutation in the p53 gene. CABA I cells grew poorly as heterotransplants in nude mice, and tumors showed long latency periods. Because early (15-20) and late (55-60) passage cells maintain the same growth and phenotypic characteristics, the CABA I cell line might provide a good in vitro model system to investigate the cellular and molecular events involved in ovarian carcinogenesis.

    Background In this pioneer study to the biological activity of organometallic compound Iron(III)-salophene (Fe-SP) the specific effects of Fe-SP on viability, morphology, proliferation, and cell-cycle progression on platinum-resistant ovarian cancer cell lines were investigated. Methodology/Principal Findings Fe-SP displayed selective cytotoxicity against SKOV-3 and OVCAR-3 (ovarian epithelial adenocarcinoma) cell lines at concentrations between 100 nM and 1 µM, while the viability of HeLa cells (epithelial cervix adenocarcinoma) or primary lung or skin fibroblasts was not affected. SKOV-3 cells in contrast to fibroblasts after treatment with Fe-SP revealed apparent hallmarks of apoptosis including densely stained nuclear granular bodies within fragmented nuclei, highly condensed chromatin and chromatin fragmentation. Fe-SP treatment led to the activation of markers of the extrinsic (Caspase-8) and intrinsic (Caspase-9) pathway of apoptosis as well as of executioner Caspase-3 while PARP-1 was deactivated. Fe-SP exerted effects as an anti-proliferative agent with an IC50 value of 300 nM and caused delayed progression of cells through S-phase phase of the cell cycle resulting in a complete S-phase arrest. When intra-peritoneally applied to rats Fe-SP did not show any systemic toxicity at concentrations that in preliminary trials were determined to be chemotherapeutic relevant doses in a rat ovarian cancer cell model. Conclusion/Significance The present report suggests that Fe-SP is a potent growth-suppressing agent in vitro for cell lines derived from ovarian cancer and a potential therapeutic drug to treat such tumors in vivo.

    To improve ovarian cancer patient survival, effective treatments addressing chemoresistant recurrences are particularly needed. Mullerian inhibiting substance (MIS) has been shown to inhibit the growth of a stem-like population of ovarian cancer cells. We have recently engineered peptide modifications to human MIS [albumin leader Q425R MIS (LRMIS)] that increase production and potency in vitro and in vivo. To test this novel therapeutic peptide, serous malignant ascites from highly resistant recurrent ovarian cancer patients were isolated and amplified to create low-passage primary cell lines. Purified recombinant LRMIS protein successfully inhibited the growth of cancer spheroids in vitro in a panel of primary cell lines in four of six patients tested. Adeno-associated virus (AAV) -delivered gene therapy has undergone a clinical resurgence with a good safety profile and sustained gene expression. Therefore, AAV9 was used as a single i.p. injection to deliver LRMIS to test its efficacy in inhibiting growth of palpable tumors in patient-derived ovarian cancer xenografts from ascites (PDXa). AAV9-LRMIS monotherapy resulted in elevated and sustained blood concentrations of MIS, which significantly inhibited the growth of three of five lethal chemoresistant serous adenocarcinoma PDXa models without signs of measurable or overt toxicity. Finally, we tested the frequency of MIS type II receptor expression in a tissue microarray of serous ovarian tumors by immunohistochemistry and found that 88% of patients bear tumors that express the receptor. Taken together, these preclinical data suggest that AAV9-LRMIS provides a potentially well-tolerated and effective treatment strategy poised for testing in patients with chemoresistant serous ovarian cancer.

    Ovarian cancer is the most lethal gynecologic cancer mainly due to spheroids organization of cancer cells that disseminate within the peritoneal cavity. We have investigated the molecular mechanisms by which ovarian cancer spheroids resist anoikis, choosing as models the 2 well-characterized human ovarian cancer cell lines IGROV1 and SKOV3. These cell lines have the propensity to float as clusters, and were isolated from tumor tissue and ascites, respectively. To form spheroids, IGROV1 and SKOV3 ovarian adenocarcinoma cells were maintained under anchorage-independent culture conditions, in which both lines survive at least a week. A short apoptotic period prior to a survival signaling commitment was observed for IGROV1 cells whereas SKOV3 cells entered G0/G1 phase of the cell cycle. This difference in behavior was due to different signals. With regard to SKOV3 cells, activation of p38 and an increase in p130/Rb occurred once anchorage-independent culture was established. Analyses of the survival signaling pathway switched on by IGROV1 cells showed that activation of ERK1/2 was required to evade apoptosis, an effect partly dependent on PKC activation and αv integrins. αv-integrin expression is essential for survival through activation of ERK1/2 phosphorylation. The above data indicate that ovarian cancer cells can resist anoikis in the spheroid state by arrest in the cell cycle or through activation of αv-integrin-ERK-mediated survival signals. Such signaling might result in the selection of resistant cells within disseminating spheroids, favoring further relapse in ovarian cancers. PMID:24291221

Preoperative chest CT findings were retrospectively evaluated in 385 surgically resected lung adenocarcinomas. A total of 30 CT descriptors were assessed. EGFR mutations at exons 18-21 were determined by using the amplification refractory mutation system. Multiple logistic regression analyses were performed to identify independent factors of harboring EGFR mutation status. The final model was selected by using the backward elimination method, and two areas under the receiver operating characteristic curve (ROC) were compared with the nonparametric approach of DeLong, DeLong, and Clarke-Pearson. Results EGFR mutations were found in 168 (43.6%) of 385 patients. Mutations were found more frequently in (a) female patients (P < .001); (b)those who had never smoked (P < .001); (c)those with lepidic predominant adenocarcinomas (P = .001) or intermediate pathologic grade (P < .001); (e) smaller tumors (P < .001); (f)tumors with spiculation (P = .019), ground-glass opacity (GGO) or mixed GGO (P < .001), air bronchogram (P = .006), bubblelike lucency (P < .001), vascular convergence (P = .024), thickened adjacent bronchovascular bundles (P = .027), or pleural retraction (P < .001); and (g) tumors without pleural attachment (P = .004), a well-defined margin (P = .010), marked heterogeneous enhancement (P = .001), severe peripheral emphysema (P = .002), severe peripheral fibrosis (P = .013), or lymphadenopathy (P = .028).

    K-ras codon 12 point mutations mRb and p53 gene deletions were examined in tissues from 120 normal lungs and lung adenocarcinomas that were Formalin-treated and paraffin-embedded 25 years ago. The results showed that 12 of 60 (20%) lung adenocarcinomas had mRb deletions. All lung adenocarcinomas that were initially found bearing deleted mRb had p53 deletions (15 of 15; 100%). A significantly higher mutation frequency for K-ras codon 12 point mutations was also found in the lung adenocarcinomas from mice exposed to 24 once-weekly neutron irradiation (10 of 10; 100%) compared with those exposed to 24 or 60 once-weekly {gamma}-ray doses (5 of 10; 50%). The data suggested that p53 and K-ras gene alterations were two contributory factors responsible for the increased incidence of lung adenocarcinoma in B6CF{sub 1} male mice exposed to protracted neutron radiation.

    From the available literature, it is unclear what proportion of pancreatic adenocarcinomas express estrogen receptors (ERα, ERβ), progesterone receptors (PR), and androgen receptors (AR), and if any of these markers have prognostic significance. We aimed to assess (1) the expression and (2) the correlation of the aforementioned markers with clinicopathological parameters and prognosis in patients with pancreatic adenocarcinoma. During a five-year period, 60 patients with pancreatic ductal adenocarcinoma underwent surgical resection at a single institution. Immunohistochemical stains of the studied markers were quantified by Image analysis system. ERα expression was positively associated with PR expression. Moreover, ERβ was inversely associated with the presence of metastases, whereas no significant associations implicated AR. As far as the prognostic significance of the studied receptors is concerned, higher ERα expression correlated with poorer survival at the univariate analysis, but the finding dissipated at the multivariate approach. No significant associations with overall survival were noted regarding the other receptors. The role of sex hormone receptors in the survival from pancreatic adenocarcinoma seems rather limited. Further prospective studies assessing those receptors should ideally be designed in order to confirm our results and possibly outline additional correlations between other steroid receptors and features of pancreatic adenocarcinoma.

    Background The detection rate of synchronous multiple lung adenocarcinomas (SMLA), which display multiple ground glass opacity nodules in the peripheral lung, is increasing due to advances in high resolution computed tomography. The backgrounds of multicentric development of adenocarcinoma are unknown. In this study, we quantitated estrogen concentration in the peripheral lungs of postmenopausal female patients with SMLA. Methods The tissue concentration of estrogens (estrone [E1] and estdadiol [E2]) in the noncancerous peripheral lung were measured with liquid chromatography/electrospray tandem mass spectrometry in postmenopausal female patients with lung adenocarcinoma. The expression levels of CYP19A1 in the normal lung were also quantitated with real-time PCR. Thirty patients with SMLA and 79 cases of control patients with single lung adenocarcinoma were analyzed. Results The concentrations of E1 and E2 in the noncancerous tissue were significantly higher in SMLA cases than control cases (P = 0.004 and P = 0.02, respectively). The minor allele (A) of single nucleotide polymorphism rs3764221 were significantly associated with higher concentration of E1 and E2 (P = 0.002 and P = 0.01, respectively) and higher CYP19A1 mRNA expression (P = 0.03). Conclusion The tissue estrogen concentration of peripheral lung was significantly higher in SMLA than control cases. The high concentration of estrogen may be one of the causes of multicentric development of peripheral lung adenocarcinomas. PMID:27526096

    SUMMARY Lung adenocarcinoma, the most common subtype of non-small cell lung cancer, is responsible for over 500,000 deaths per year worldwide. Here, we report exome and genome sequences of 183 lung adenocarcinoma tumor/normal DNA pairs. These analyses revealed a mean exonic somatic mutation rate of 12.0 events/megabase and identified the majority of genes previously reported as significantly mutated in lung adenocarcinoma. In addition, we identified statistically recurrent somatic mutations in the splicing factor gene U2AF1 and truncating mutations affecting RBM10 and ARID1A. Analysis of nucleotide context-specific mutation signatures grouped the sample set into distinct clusters that correlated with smoking history and alterations of reported lung adenocarcinoma genes. Whole genome sequence analysis revealed frequent structural re-arrangements, including in-frame exonic alterations within EGFR and SIK2 kinases. The candidate genes identified in this study are attractive targets for biological characterization and therapeutic targeting of lung adenocarcinoma. PMID:22980975

    ATP-binding cassette transporter E1 (ABCE1), also known as RLI (RNase L inhibitor), is a new type of endoribonuclease inhibitor, which can specifically bind to RNase L and abolish its effect. ABCE1 binds to eIF2α and eIF5 to form a pre-translation initiation complex, suggesting its crucial role in cell growth, development and certain pathological processes. To probe the role of ABCE1 in the development and progress of human lung adenocarcinoma, we first detected the changes of its mRNA and protein expression in tissues, and found a high expression level of ABCE1 in human lung adenocarcinoma tissues and metastatic lymph nodes, which was also correlated with clinical stages. Moreover, human lung adenocarcinoma A549 cells were infected with lentiviral vectors containing ABCE1-specific shRNA, and resulted in significant inhibition of cell growth. Using microarray assay, a number of differentially expressed genes were found after ABCE1 suppression. Our results demonstrated the potential role of ABCE1 in human lung adenocarcinoma, which may provide some molecular basis for the mechanisms of development and progress of human lung adenocarcinoma, and help to find new pharmacological targets.

    Pathological diagnosis is influenced by subjective factors such as the individual experience and knowledge of doctors. Therefore, it may be interpreted in different ways for the same symptoms. The appearance of digital pathology has created good foundation for objective diagnoses based on quantitative feature analysis. Recently, numerous studies are being done to develop automated diagnosis based on the digital pathology. But there are as of yet no general automated methods for pathological diagnosis due to its specific nature. Therefore, specific methods according to a type of disease and a lesion could be designed. This study proposes quantitative features that are designed to diagnose pancreatic ductal adenocarcinomas. In the diagnosis of pancreatic ductal adenocarcinomas, the region of interest is a duct that consists of lumen and epithelium. Therefore, we first segment the lumen and epithelial nuclei from a tissue image. Then, we extract the specific features to diagnose the pancreatic ductal adenocarcinoma from the segmented objects. The experiment evaluated the classification performance of the SVM learned by the proposed features. The results showed an accuracy of 94.38% in the experiment distinguishing between pancreatic ductal adenocarcinomas and normal tissue and a classification accuracy of 77.03% distinguishing between the stages of pancreatic ductal adenocarcinomas.

    In recent decades there has been a dramatic rise in the incidence of esophageal adenocarcinoma (EAC) in the developed world. Over approximately the same period there has also been an increase in the prevalence of obesity. Obesity, especially visceral obesity, is an important independent risk factor for the development of gastro-esophageal reflux disease, Barrett’s esophagus and EAC. Although the simplest explanation is that this mediated by the mechanical effects of abdominal obesity promoting gastro-esophageal reflux, the epidemiological data suggest that the EAC-promoting effects are independent of reflux. Several, not mutually exclusive, mechanisms have been implicated, which may have different effects at various points along the reflux-Barrett’s-cancer pathway. These mechanisms include a reduction in the prevalence of Helicobacter pylori infection enhancing gastric acidity and possibly appetite by increasing gastric ghrelin secretion, induction of both low-grade systemic inflammation by factors secreted by adipose tissue and the metabolic syndrome with insulin-resistance. Obesity is associated with enhanced secretion of leptin and decreased secretion of adiponectin from adipose tissue and both increased leptin and decreased adiponectin have been shown to be independent risk factors for progression to EAC. Leptin and adiponectin have a set of mutually antagonistic actions on Barrett’s cells which appear to influence the progression of malignant behaviour. At present no drugs are of proven benefit to prevent obesity associated EAC. Roux-en-Y reconstruction is the preferred bariatric surgical option for weight loss in patients with reflux. Statins and aspirin may have chemopreventative effects and are indicated for their circulatory benefits. PMID:25400997

    Pancreatic ductal adenocarcinoma (PDAC) is an incurable lethal disease whose incidence rate is growing. There is no effective screening for detection of early stage tumors and, in most cases, PDAC is diagnosed at advanced disease stages, when radical pancreatic resection is not possible. The aggressive nature of pancreatic tumor cells lies in the complex genetic mechanisms behind their uncontrolled capability to grow and metastasize, which involve essential adaptive changes in cellular metabolism, signaling, adhesion and immunoediting. In addition, PDAC cells promote a dense functional stroma that facilitates tumor resistance to chemotherapy and radiation. During the last two decades, gemcitabine has been the reference for the systemic treatment of PDAC. However, recently, a regimen combining fluorouracil, irinotecan, oxaliplatin, and leucovorin (FOLFIRINOX) and another combining albumin-bound paclitaxel with gemcitabine have shown clear therapeutic advantage in advanced PDAC, with survival outcomes of 11.3 and 8.5 mo on phase III trials, respectively, over single-agent gemcitabine. With the pending issue of their higher toxicities, these regimens set the reference for ongoing and future clinical studies in advanced PDAC. In addition, the efficacy of oral fluoropyrimidine (S-1) has been well documented in Asiatic PDAC patients. The development of therapeutic approaches other than cytotoxic drugs has proven difficult in the past, with only one drug (erlotinib) approved to date. Besides, a number of agents targeting signaling pathways in tumor or stroma cells are being investigated. Likewise, immunotherapies that target PDAC in various ways are the subject of a number of clinical trials. The search for reliable biomarkers with diagnostic and prognostic value using genomics and mass spectrometry methods may facilitate monitoring and refinement of therapies. This review focuses on current understanding of the pathogenesis of PDAC and the latest developments in the

    Instability of tandem repeat sequences (microsatellites) has been reported to play a major etiologic role in familial colon cancer, as well as a potential role in the carcinogenesis of other sporadic neoplasms. These replication errors are the result of faulty DNA excision/repair function controlled at the gene level. In order to examine this phenomenon in prostate cancer, we screened 40 tumors with di-, tri- and tetranucleotide markers spanning eleven chromosomal loci. Microsatellite instability was observed overall in 3 of the 40 cases (7.5%). All changes were identified solely in tetranucleotide sequences (3 of 11 total markers analyzed). One tumor demonstrated repeat length expansions at two loci, while the other tumors did so at a single locus. Both Type 1 (>4 base pairs) and Type II (4 base pairs) mutations were identified. One of these cases also included metastatic nodal disease. Analysis of the metastatic tumor tissue revealed allelic patterns identical to the normal tissue control. A secondary screening of the mutated tumors demonstrated no repeat length alterations in 16 additional markers. A CAG repeat in the androgen receptor (AR) gene was also studied and demonstrated that 3 of 40 (7.5%) tumors contained mutations within this repeat. We concluded that microsatellite instability is uncommon in prostate adenocarcinoma appearing to occur more often in tetranucleotide repeat sequences and in an AR gene repeat. Additionally, these findings suggest that dysfunctional DNA excision/repair mechanisms, as evidenced by the low frequency of replication errors, are unlikely to play a major role in the natural history of prostate cancer.

  5. Gemcitabine resistance in pancreatic ductal adenocarcinoma.

    Pancreatic ductal adenocarcinoma (PDA) ranks fourth among cancer related deaths. The disappointing 5-year survival rate of below 5% stems from drug resistance to all known therapies, as well as from disease presentation at a late stage when PDA is already metastatic. Gemcitabine has been the cornerstone of PDA treatment in all stages of the disease for the last two decades, but gemcitabine resistance develops within weeks of chemotherapy initiation. From a mechanistic perspective, gemcitabine resistance may result from alterations in drug metabolism until the point that the cytidine analog is incorporated into the DNA, or from mitigation of gemcitabine-induced apoptosis. Both of these drug resistance modalities can be either intrinsic to the cancer cell, or influenced by the cancer microenvironment. Mechanisms of intrinsic gemcitabine resistance are difficult to tackle, as many of the genes that drive the carcinogenic process itself also interfere with gemcitabine-induced apoptosis. In this regard, recent understanding of the involvement of microRNAs in gemcitabine resistance may offer new opportunities to overcome intrinsic gemcitabine resistance. The characteristically fibrotic and immune infiltrated stroma of PDA that accompanies tumor inception and expansion is a lush ground for treatments aimed at targeting tumor microenvironment-mediated drug resistance. In the last couple of years, drugs interfering with tumor microenvironment have matured to clinical trials. Although drugs inducing 'stromal depletion' have yet failed to improve survival, they have greatly increased our understanding of tumor microenvironment-mediated drug resistance. In this review we summarize the current knowledge on intrinsic and environment-mediated gemcitabine resistance, and discuss the impact of these pathways on patient screening, and on future treatments aimed to potentiate gemcitabine activity.

    The International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society and 2015 World Health Organization classifications of lung adenocarcinoma recommend designating tumors showing entirely lepidic growth as adenocarcinoma in situ (AIS) and lepidic tumors with invasion less than or equal to 5 mm as minimally invasive adenocarcinoma (MIA), both of which have superior outcome to conventional invasive adenocarcinoma (IA). Data on interobserver variability within this classification are limited, and further validation of the superior survival of AIS and MIA is needed. A total of 296 surgically excised pulmonary adenocarcinomas were reviewed from 254 patients (1997-2009). Slides were independently reviewed by 2 pulmonary pathologists who categorized tumors as AIS, MIA, or IA. Of 296 nodules, 244 (82.4%) were agreed upon by both observers: 10 AIS, 61 MIA, and 173 IA (κ = 0.63, good agreement). In 6 cases (2%), there was disagreement between AIS and MIA; in 45 cases (15%), there was disagreement between MIA and IA; and in 1 case, there was disagreement between AIS and IA. Overall survival was significantly different among categories as determined by both observers. Cases with disagreement between MIA and IA had similar survival to agreed MIA. Disease-specific 10-year survival was 100% for AIS (both observers) and 97.3% and 97.6% for MIA, although this did not reach statistical significance compared to IA for either observer. Good agreement was present between observers when classifying tumors as AIS, MIA, and IA. Significant differences in overall survival were present between the 3 groups for both observers, and interobserver variability was evident. Patients with AIS and MIA experienced excellent DSS.

    Background Epidermal growth factor receptor (EGFR) is overexpressed in many solid tumor types, such as ovarian carcinoma. Immunoliposome based drug targeting has shown promising results in drug delivery to the tumors. However, the ratio of tumor-to-normal tissue concentrations should be increased to minimize the adverse effects of cytostatic drugs. Methodology/Principal Findings We studied the EGFR-targeted doxorubicin immunoliposomes using pre-targeting and local intraperitoneal (i.p.) administration of the liposomes. This approach was used to increase drug delivery to tumors as compared to direct intravenous (i.v.) administration of liposomes. EGFR antibodies were attached on the surface of PEG coated liposomes using biotin-neutravidin binding. Receptor mediated cellular uptake and cytotoxic efficacy of EGFR-targeted liposomes were investigated in human ovarian adenocarcinoma (SKOV-3 and SKOV3.ip1) cells. In vivo distribution of the liposomes in mice was explored using direct and pre-targeting approaches and SPECT/CT imaging. Targeted liposomes showed efficient and specific receptor-mediated binding to ovarian carcinoma cells in vitro, but the difference in cytotoxicity between targeted and non-targeted liposomes remained small. The relatively low cytotoxic efficacy is probably due to insufficient doxorubicin release from the liposomes rather than lack of target binding. Tumor uptake of targeted liposomes in vivo was comparable to that of non-targeted liposomes after both direct and pre-targeting administration. For both EGFR-targeted and non-targeted liposomes, the i.p. administration increased liposome accumulation to the tumors compared to i.v. injections. Conclusions/Significance Intraperitoneal administration of liposomes may be a beneficial approach to treat the tumors in the abdominal cavity. The i.p. pre-targeting method warrants further studies as a potential approach in cancer therapy. PMID:22844475

    HLA-G is an immune tolerant with seven isoforms. HLA-G expression was observed to be associated with tumor cell immune escaping, invasion and metastasis, and with poor prognosis in cancer patients. Different types of HLA-G isoforms could be expressed in clinical settings when meet different cellular and environmental conditions. Lesion total HLA-G expression detected by the monoclonal antibody (mAb) 4H84 was widely investigated in previous studies, while specific HLA-G isoforms such as HLA-G5/-G6 remains to be clarified. In this study, 118 primary ovarian cancer lesions were probed with mAb 5A6G7 which recognizes HLA-G5/-G6 was performed by immunohistochemistry. Data showed that HLA-G5/-G6 was expressed in 79.7% (94/118) of these ovarian cancer lesions, where HLA-G5/-G6 expression was observed in 75.7% (53/70) serous, 63.6% (7/11) mucinous cystadenocarcinoma and in 100% (11/11) endometrioid adenocarcinoma, in 85.7% (6/7) clear cell carcinoma, 100% (10/10) sex cord-stromal tumor and 77.8% (7/9) germ cell tumors. However, lesion HLA-G5/-G6 expression was unrelated to histological type, patient age, FIGO stage and patient survival. Unlike total HLA-G expression, no clinical significance of HLA-G5/-G6 expression in ovarian cancer lesion was observed in this study. Our findings indicated that different HLA-G isoforms might have different biological functions in malignancies. PMID:26687271

    Radiation and high-dose chemotherapy may render women with cancer prematurely sterile, a side-effect that would be avoided if ovarian tissue that had been removed before treatment could be made to function afterwards. Live offspring have been produced from transplanted ovarian tissue in mice and sheep but not in monkeys or humans, although sex steroid hormones are still secreted. Here we describe the successful transplantation of fresh ovarian tissue to a different site in a monkey, which has led to the birth of a healthy female after oocyte production, fertilization and transfer to a surrogate mother. The ectopically grafted tissue functions without surgical connection to major blood vessels and sets the stage for the transplantation of cryopreserved ovarian tissue in humans.

    Cancer markers may be developed to detect diseases characterized by increased expression of apoptosis-suppressing genes, such as aggressive cancers. Genes in the human chromosomal regions, 8q24, 11q13, 20q11-q13, were found to be amplified indicating in vivo drug resistance in diseases such as ovarian cancer. Diagnosis and assessment of amplification levels certain genes shown to be amplified, including PVT1, can be useful in prediction of poor outcome of patient's response and drug resistance in ovarian cancer patients with low survival rates. Certain genes were found to be high priority therapeutic targets by the identification of recurrent aberrations involving genome sequence, copy number and/or gene expression are associated with reduced survival duration in certain diseases and cancers, specifically ovarian cancer. Therapeutics to inhibit amplification and inhibitors of one of these genes, PVT1, target drug resistance in ovarian cancer patients with low survival rates is described.

    Endoscopic ovarian biopsies were performed on 78 amenorrheic patients in an attempt to determine the etiology of their amenorrhea and predict its prognosis, correlating the histologic examination with physical findings, endocrine patterns and cytogenetic studies. Ovarian follicles were present while gonadotropins were high in 14 cases (6 primary, 8 secondary) and there were no follicles in 4 cases (3 primary, 1 secondary) whose gonadotropins were low. Secondary sex characteristics were well developed without prior estrogen stimulation in 5 cases of primary amenorrhea who had no follicles and whose gonadotropins were either low, 3, or high, 2. The mere presence of ovarian follicles was not enough to make them responsive to gonadotropin stimulation whether endogenous or exogenous; a phenomenon that had to do with the quality and quantity of germinal follicles available. The histologic examination of ovarian tissue for the evaluation of amenorrhea has been made feasible and relatively safe through recent advances in endoscopic techniques. PMID:151477

    Borderline mucinous tumors are epithelial ovarian tumors with low rate of growth and low potential to invade or metastasize and associated with significantly better prognosis and excellent disease-free survival after surgical removal than other epithelial ovarian cancers. The accepted initial treatment is surgical removal of the tumor. Fertility-sparing surgery may suffice in young patients with tumors confined to the ovary. Radical surgery is recommended in patients with advanced disease and advanced age. Long-term surveillance is recommended to document and treat late recurrences. We report a case of a 59 years old postmenopausal patient with complex ovarian mucinous tumor and gross ascites; she had received three lines of chemotherapeutic agents pre-operatively, without any favorable outcome. Then, she went for staging laparotomy and histopathology showed borderline ovarian mucinous tumor required no further treatment and is fine till date. PMID:25518783

    Epithelial ovarian cancer represents the most lethal gynecological malignancy in the developed world, and can be divided into five main histological subtypes: high grade serous, endometrioid, clear cell, mucinous and low grade serous. These subtypes represent distinct disease entities, both clinically and at the molecular level. Molecular analysis has revealed significant genetic heterogeneity in ovarian cancer, particularly within the high grade serous subtype. As such, this subtype has been the focus of much research effort to date, revealing molecular subgroups at both the genomic and transcriptomic level that have clinical implications. However, stratification of ovarian cancer patients based on the underlying biology of their disease remains in its infancy. Here, we summarize the molecular changes that characterize the five main ovarian cancer subtypes, highlight potential opportunities for targeted therapeutic intervention and outline priorities for future research.

    Ovarian cancer is a leading cause of cancer-related women mortality in China. In recent years, the molecular mechanisms involved in ovarian carcinoma development and/or progression have been intensely studied, and several genes have been identified. Deleted in Colorectal Carcinoma (DCC), is an important tumor suppressor gene, which is inactivated in many kinds of tumors, and its function(s) is not clarified. Even though the lost expression of DCC occurred in later stages of multistep colorectal carcinogenesis, its contribution to the onset or progression of ovarian cancer is not fully understood. To investigate DCC expression in ovarian cancer, we studied 254 clinical samples by RT-PCR. Our results revealed that 52% malignant ovarian cancer did not express DCC gene. By contrast, DCC expression was observed in all normal ovary tissues and 80% benign ovarian tumors. Obviously, there was a significant correlation between DCC expression and ovarian cancer, especially in the epithelial ovarian cancer. The present study also suggested that the loss expression of DCC occurred more frequently in the cases of later clinical stage, higher pathological grade, and poorer prognosis. In the other part of this study, we further explored DCC expression after transfection in two kinds of ovarian cancer cell lines, namely SKOV3 cell and HO-8910 cell, using RT-PCR and immunocytochemistry. The results indicated that DCC expressed in SKOV3-DCC and HO-8910-DCC cells, and ultrastructural analysis showed the appearance of apoptotic features in them. Furthermore, cell growth was markedly down-regulated in above groups of cells, indicating that transfection with the DCC constructs can suppress the growth of tumor cells. In conclusion, our results suggest an association of lost expression of DCC with the ovarian cancer, and DCC gene may inhibit the growth of ovarian carcinoma cells. However, this result needs further trials with a larger sample. PMID:20054719
