Carbohydrate antigen 19-9 (CA 19-9) is a tumour marker found to be elevated in some ovarian tumours. We share our experience with a 55-year-old postmenopausal lady with unusually high CA19-9 levels arising from a benign mucinous cystadenoma of the ovary. The levels returned to normal eight weeks following staging laparotomy and a total abdominal hysterectomy with bilateral salpingo-oopherectomy. This report shows rare and significant elevation of CA 19-9 levels with benign mucinous cystadenomas of the ovary thus showing that women with unusually elevated tumour markers may actually harbour benign disease...

Endometrioid Stromal Sarcoma (ESS) is an uncommon tumour that occurs in women over wide age range of 11 years to 76 years accounting for only 0.2% of all uterine malignancies and for 15%-26% of primary uterine sarcomas. These tumours arising from ovary are extremely rare. Most of them are associated with nulliparous or perimenopausal women. It is commonly associated with endometriosis of the ovary. Here we present this rare case to emphasize on the uniqueness and histomorphology of ovarian ESS in patients with endometriosis...

Testicular and paratesticular cystadenomas arise from an oviduct-like structure, which, morphologically, is almost identical with the ovarian surface epithelium. These are very rare benign tumours of adults. They present as asymptomatic cystic lesions. Bilateral paratesticular cystadenomas are associated with the Von-Hippel-Lindau syndrome and may be associated with infertility. Most cystadenomas are benign, but a few cases of malignant transformation of embryonic remnants have been reported in the appendix testis, including cases of adenocarcinoma, cystadenocarcinoma, and a Müllerian-type epithelial tumour with a low malignant potential...

Background: High-dose chemotherapy (HDC) with hematopoietic progenitor cell transplantation is a standard option for relapsed/refractory testicular germ cell tumor (GCT), but only few data have been reported in female patients with GCT. We conducted a retrospective analysis of female patients with GCT treated with HDC and registered with the European Society for Blood and Marrow Transplantation (EBMT). Patients and methods: Between 1985 and 2013, 60 registered female patients with GCT, median age 27 years (range 15-48), were treated with salvage HDC...

BACKGROUND: Intestinal differentiation of primary mucinous adenocarcinoma of the uterine corpus is exceedingly rare in comparison to the approximately 25% rate in endocervical and ovarian mucinous carcinoma. Additionally, little is known about the related genetic and epigenetic alterations, even though large-scale molecular characterisation of the different types of endometrial cancer took place in the TCGA project along the entities defined by the recent WHO classification. CASE PRESENTATION: We present a 62-year-old patient harbouring a primary mucinous carcinoma of the uterine corpus with a morphological resemblance to mucinous colorectal adenocarcinoma...

The RUNX1 transcription factor is a critical regulator of normal haematopoiesis and its functional disruption by point mutations, deletions or translocations is a major causative factor leading to leukaemia. In the majority of cases, genetic changes in RUNX1 are linked to loss of function classifying it broadly as a tumour suppressor. Despite this, several recent studies have reported the need for a certain level of active RUNX1 for the maintenance and propagation of acute myeloid leukaemia and acute lymphoblastic leukaemia cells, suggesting an oncosupportive role of RUNX1...

BACKGROUND: While the requirement for thresholds for testing for mutations in BRCA1/2 is being questioned, they are likely to remain for individuals unaffected by a relevant cancer. It is still useful to provide pretesting likelihoods, but models need to take into account tumour pathology. METHODS: The Manchester Scoring System (MSS) is a well-used, simple, paper-based model for assessing carrier probability that already incorporates pathology data. We have used mutation testing data from 4115 unrelated samples from affected non-Jewish individuals alongside tumour pathology to further refine the scoring system...

Ovarian Sertoli-Leydig cell tumours (OSLCT) are rare and typically present with androgenic manifestations in women of the 2nd-3rd decade. Out of 228 diagnoses of ovarian sex cord-stromal tumours recorded at an academic institution during a 14-year period, eight women were surgically treated for OSLCT. Patient mean age was 54.8 years (range 19-81), five women being in the postmenopausal stage (62.5%). Only one woman presented with androgenic manifestations (12.5%), four with abnormal/postmenopausal uterine bleeding (50%), and three with abdominal pain (37...

This is the first study performed in Murcia (south-eastern Spain) in which 592 families with hereditary breast and ovarian cancer were identified thanks to Genetic Counselling Units from this area over 6 years. Diagnostic performance was 18.1% and 194 different genetic variants were obtained. Variants with uncertain significance accounted for only 5.6% of the total number of reports, so our population has been well characterised. In BRCA1 gene, two novel variants were found (c.1859delT and c.3205C > T) and the most frequently detected mutations were c...

Subtilase cytotoxin (SubAB) of Escherichia coli is an AB5 class bacterial toxin. The pentameric B subunit (SubB) binds the cellular carbohydrate receptor, α2-3-linked N-glycolylneuraminic acid (Neu5Gc). Neu5Gc is not expressed on normal human cells, but is expressed by cancer cells. Elevated Neu5Gc has been observed in breast, ovarian, prostate, colon and lung cancer. The presence of Neu5Gc is prognostically important, and correlates with invasiveness, metastasis and tumour grade. Neu5Gc binding by SubB suggests that it may have utility as a diagnostic tool for the detection Neu5Gc tumor antigens...

Sclerosing stromal tumours are rare benign ovarian neoplasms of the sex cord stromal that occur predominantly in the second and third decades of life. To date, fewer than 200 cases have been described in the literature and most patients have menstrual irregularities and pelvic pain. Sclerosing stromal tumours were reported in which the inactive tumours did not represent endocrine clinical symptoms; however, currently according to several reports, it is the active tumour that produce hormones. Only a few cases of virilizing sclerosing stromal tumours of the ovary have been described in the literature and in this report first describes sclerosing stromal tumour of the ovary in a postmenopausal woman presenting with virilization...

Lynch syndrome, caused by germline mutations in the mismatch repair genes, is associated with increased cancer risk. Here using a large whole-genome sequencing data bank, cancer registry and colorectal tumour bank we determine the prevalence of Lynch syndrome, associated cancer risks and pathogenicity of several variants in the Icelandic population. We use colorectal cancer samples from 1,182 patients diagnosed between 2000-2009. One-hundred and thirty-two (11.2%) tumours are mismatch repair deficient per immunohistochemistry...

BACKGROUND: The relationship between diet and survival after ovarian cancer diagnosis is unclear as a result of a limited number of studies and inconsistent findings. METHODS: We examined the association between pre-diagnostic diet and overall survival in a population-based cohort (n=811) of Australian women diagnosed with invasive epithelial ovarian cancer between 2002 and 2005. Diet was measured by validated food frequency questionnaire. Deaths were ascertained up to 31 August 2014 via medical record review and Australian National Death Index linkage...

Epithelial ovarian cancer is a highly lethal disease, which is usually diagnosed at a late stage with extensive metastases in the abdominal cavity. Ovarian cancer either develops from the ovarian surface epithelium (OSE) or from serous intra-epithelial carcinoma (STIC). Primary therapy consists of debulking surgery and platinum based chemotherapy. The success of debulking surgery depends on surgical skills but also on the gene signature of the tumour. Debulking surgery combined with first line platinum based chemotherapy, frequently leads to complete remission...

To study the effect of liriopesides B on cell growth curve, cell doubling time, the activity of tumour marker CA125 and alkaline phosphatase (AKP) in human ovarian cancer A2780 cells. Both cell growth curve and doubling time were studied by MTT assay, CA125 level and AKP activity were determined by respective kits. Results showed that liriopesides B could shift down the A2780 cells growth curve in a dose-time-dependent manner and inhibit the proliferation in A2780 cells with the maximum inhibitory rate 94.462% at 120 h, the doubling time was prolonged too...

BACKGROUND: Ovarian cancer is the leading cause of death for gynecological cancers and the 6th cause of women cancer death in developed countries. The late stage detection, the peritoneal dissemination and the acquisition of resistance against carboplatin are the main reasons to explain this poor prognosis and strengthen the need of alternative treatments to improve the management of ovarian cancer and/or to sensitize tumors to platinum salts. Epidermal growth factor receptor (EGFR), hepatocyte growth factor receptor (Met) and cellular Src kinase (c-Src) are crucial kinases implied in ovarian tumor growth, survival, invasion and resistance to carboplatin...

OBJECTIVES: Approximately 1 % of all malignant solid tumours of the head and neck area are metastases from primary tumours beneath the clavicles. The aim of this study was to analyse the distribution of primary tumours since meta-analyses might have been biased due to the usually extraordinary character of case reports. MATERIALS AND METHODS: All patient files from 1970 to 2012 from the Oral and Maxillofacial Surgery unit at a University Hospital were analysed regarding the existence of metastases to the head and neck area from distant primaries...
