A bespoke target selection tool to guide biomarker discovery in tubo-ovarian cancer.

Introduction: Cancers presenting at advanced stages inherently have poor prognosis. High grade serous carcinoma (HGSC) is the most common and aggressive form of tubo-ovarian cancer. Clinical tests to accurately diagnose and monitor this condition are lacking.

Liquid biopsy in ovarian cancer: Catching the silent killer before it strikes.

Epithelial ovarian cancer (EOC) is the most lethal gynaecological malignancy in the western world. The majority of women presenting with the disease are asymptomatic and it has been dubbed the "silent killer". To date there is no effective minimally invasive method of stratifying those with the disease or screening for the disease in the general population.

FKBPL-based peptide, ALM201, targets angiogenesis and cancer stem cells in ovarian cancer.

Background: ALM201 is a therapeutic peptide derived from FKBPL that has previously undergone preclinical and clinical development for oncology indications and has completed a Phase 1a clinical trial in ovarian cancer patients and other advanced solid tumours.

Methods: In vitro, cancer stem cell (CSC) assays in a range of HGSOC cell lines and patient samples, and in vivo tumour initiation, growth delay and limiting dilution assays, were utilised. Mechanisms were determined by using immunohistochemistry, ELISA, qRT-PCR, RNAseq and western blotting.

Defining the molecular evolution of extrauterine high grade serous carcinoma.

Objective: High grade serous carcinoma (HGSC) is the most common and most aggressive, subtype of epithelial ovarian cancer. It presents as advanced stage disease with poor prognosis. Recent pathological evidence strongly suggests HGSC arises from the fallopian tube via the precursor lesion; serous tubal intraepithelial carcinoma (STIC).

Early catheter removal following laparoscopic radical hysterectomy for cervical cancer: assessment of a new bladder care protocol.

Evidence to support prolonged catheterisation after radical hysterectomy is lacking. We sought to assess feasibility of a new protocol of early post-operative catheter removal following laparoscopic radical hysterectomy for cervical cancer. A retrospective review of post-operative bladder care in patients who underwent laparoscopic radical hysterectomy for cervical cancer was carried out.

Apneic Oxygenation Versus Low-Tidal-Volume Ventilation in Anesthetized Cardiac Surgical Patients: A Prospective, Single-Center, Randomized Controlled Trial.

Objectives: To compare the physiology of apneic oxygenation with low-tidal-volume (VT) ventilation during harvesting of the left internal mammary artery.

Design: Prospective, single-center, randomized trial.

Setting: Single-center teaching hospital.

A rare case of HPV-negative cervical squamous cell carcinoma.

It is generally assumed that virtually all cervical squamous cell carcinomas are associated with persistent infection by high-risk human papillomavirus (HPV), although it is well known that unusual variants of cervical adenocarcinoma are mostly HPV negative. We report a case of a well-differentiated cervical squamous cell carcinoma in a 54-yr-old woman, the morphologic features of which suggested a non-HPV-related neoplasm. The tumor was p16 negative.

BRCA1 immunohistochemical staining as a prognostic indicator in uterine serous carcinoma.

Objectives: The objective of this study was to investigate the relationship between BRCA1 protein expression, as determined by immunohistochemistry, and clinical outcome in uterine serous carcinoma (USC).

Methods: A tissue microarray containing duplicate cores of 73 cases of USC was immunohistochemically stained with mouse anti-BRCA1 (Ab-1) mouse monoclonal (MS110) antibody. The cores were scored in a semiquantitative manner evaluating both the distribution and intensity of nuclear staining.

Diagnostic accuracy of magnetic resonance imaging in endometrial cancer.

Objectives: The objectives of this study were to investigate the accuracy of magnetic resonance imaging (MRI) in predicting the depth of myometrial invasion in the preoperative assessment of women with endometrial cancer and to quantify the impact of MRI as an adjunct to predicting patients requiring full surgical staging.

Methods: This was a diagnostic accuracy study of prospective cases in conjunction with STARD guidelines using collected data from a tumor board within a cancer network. Consecutive series of all endometrial cancers in Northern Ireland over a 21-month period was discussed at the Gynaecological Oncology Multidisciplinary Team/tumor board meeting.

Composite cervical adenocarcinoma composed of adenoma malignum and gastric type adenocarcinoma (dedifferentiated adenoma malignum) in a patient with Peutz Jeghers syndrome.

An unusual cervical adenocarcinoma is reported in a 50-year-old woman with a history of Peutz Jeghers syndrome. The carcinoma contained two morphologically distinct and spatially separate components, one comprising typical well differentiated adenoma malignum and the other a moderately differentiated neoplasm, in keeping with gastric type adenocarcinoma. Both components were positive for HIK1083 and MUC6 and negative for p16, and did not contain human papillomavirus.

Role of adjuvant radiotherapy in granulosa cell tumors of the ovary.

Purpose: To review the role of adjuvant radiotherapy (RT) in the outcome and recurrence patterns of granulosa cell tumors (GCTs) of the ovary.

Methods And Materials: The records of all patients with GCTs referred to the Princess Margaret Hospital University Health Network between 1961 and 2006 were retrospectively reviewed. The patient, tumor, and treatment factors were assessed by univariate and multivariate analyses using disease-free survival (DFS) as the endpoint.

Ovarian cancer risk is associated with a common variant in the promoter sequence of the mismatch repair gene MLH1.

Objectives: Inherited mutations in the MLH1 gene are associated with a proportion of families with the hereditary non-polyposis colon cancer syndrome (HNPCC). The cardinal features of the syndrome are a predisposition to colon, endometrial and ovarian cancers. Recently, it has been shown that a non-coding polymorphic variant in MLH1 (G>A nt-93) predisposes to colon and endometrial cancer, but with much reduced penetrance.

Sentinel lymph node in vulvar cancer.

Background: The aim of the study was to assess the feasibility, efficacy, and accuracy of the sentinel lymph node (SLN) procedure in vulvar cancer.

Methods: From April 2004 to September 2006, all patients with vulvar cancer, clinical stages I and II, underwent SLN detection, followed by a complete inguinofemoral lymphadenectomy. Demographic, surgical, and pathologic data on all patients were prospectively entered in a database.

Endometrial cancer risk is associated with variants of the mismatch repair genes MLH1 and MSH2.

Women with germ-line mutations in the mismatch repair genes (responsible for hereditary nonpolyposis colorectal cancer) face an increased risk of colonic and endometrial cancer. However, these germ-line mutations are rare and are responsible for fewer than 1% of endometrial cancers. Therefore, we examined whether or not common variants of the hereditary nonpolyposis colorectal cancer-associated genes might also be associated with an increased risk of endometrial cancer.
