Abstract
PURPOSE Prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) scan is the standard imaging procedure for biochemical recurrent prostate cancer postprostatectomy because of its high detection rate at low serum prostate-specific antigen levels. However, existing guidelines for clinical target volume (CTV) in prostate bed salvage external beam radiation therapy (sEBRT) are primarily based on experience-based clinical consensus and have been validated using conventional imaging modalities. Therefore, this study aimed to optimize CTV definition in sEBRT by using PSMA PET/CT-detected local recurrences (LRs). METHODS AND MATERIALS Patients with suspected LR on PSMA PET/CT postprostatectomy were retrospectively enrolled in 9 Dutch centers. Anonymized scans were centrally reviewed by an expert nuclear medicine physician. Each boundary of the CTV guideline from the Groupe Francophone de Radiothérapie en Urologie (GFRU) was evaluated and adapted to improve the accuracy and coverage of the area at risk of LR (CTV) on PSMA PET/CT. The proposed CTV adaptation was discussed with the radiation oncologists of the participating centers, and final consensus was reached. To assess reproducibility, the participating centers were asked to delineate 3 new cases according to the new PERYTON-CTV, and the submitted contours were evaluated using the Dice similarity coefficient (DSC). RESULTS After central review, 93 LRs were identified on 83 PSMA PET/CTs. The proposed CTV definition improved the coverage of PSMA PET/CT-detected LRs from 67% to 96% compared with the GFRU-CTV, while reducing the GFRU-CTV by 25%. The new CTV was highly reproducible, with a mean DSC of 0.82 (range, 0.81-0.83). CONCLUSIONS This study contributes to the optimization of CTV definition in postprostatectomy sEBRT by using the pattern of LR detected on PSMA PET/CT. The PERYTON-CTV is highly reproducible across the participating centers and ensures coverage of 96% LRs while reducing the GFRU-CTV by 25%.

Abstract
Purpose The PERYTON trial is a multicenter randomized controlled trial that will investigate whether the treatment outcome of salvage external beam radiation therapy (sEBRT) will be improved with hypofractionated radiation therapy. A pretrial quality assurance (QA) program was undertaken to ensure protocol compliance within the PERYTON trial and to assess variation in sEBRT treatment protocols between the participating centers. Methods and Materials Completion of the QA program was mandatory for each participating center (N = 8) to start patient inclusion. The pretrial QA program included (1) a questionnaire on the center-specific sEBRT protocol, (2) a delineation exercise of the clinical target volume (CTV) and organs at risk, and (3) a treatment planning exercise. All contours were analyzed using the pairwise dice similarity coefficient (DSC) and the 50th and 95th percentile Hausdorff distance (HD50 and HD95, respectively). The submitted treatment plans were reviewed for protocol compliance. Results The results of the questionnaire showed that high-quality, state-of-the-art radiation therapy techniques were used in the participating centers and identified variations of the sEBRT protocols used concerning the position verification and preparation techniques. The submitted CTVs showed significant variation, with a range in volume of 29 cm3 to 167 cm3, a mean pairwise DSC of 0.52, and a mean HD50 and HD95 of 2.3 mm and 24.4 mm, respectively. Only in 1 center the treatment plan required adaptation before meeting all constraints of the PERYTON protocol. Conclusions The pretrial QA of the PERYTON trial demonstrated that high-quality, but variable, radiation techniques were used in the 8 participating centers. The treatment planning exercise confirmed that the dose constraints of the PERYTON protocol were feasible for all participating centers. The observed variation in CTV delineation led to agreement on a new (image-based) delineation guideline to be used by all participating centers within the PERYTON trial.

Abstract
Disorders of gut-brain interaction (DGBI), formerly termed functional gastrointestinal disorders (FGID), are highly prevalent although exact pathophysiological mechanisms remain unclear. Intestinal immune activation has been recognized, but increasing evidence supports a pivotal role for an active inflammatory state in these disorders. In functional dyspepsia (FD), marked eosinophil and mast cell infiltration has been repeatedly demonstrated and associations with symptoms emphasize the relevance of an eosinophil-mast cell axis in FD pathophysiology. In this Review, we highlight the importance of immune activation in DGBI with a focus on FD. We summarize eosinophil biology in both homeostasis and inflammatory processes. The evidence for immune activation in FD is outlined with attention to alterations on both cellular and molecular level, and how these may contribute to FD symptomatology. As DGBI are complex and multifactorial conditions, we shed light on factors associated to, and potentially influencing immune activation, including bidirectional gut-brain interaction, allergy and the microbiota. Crucial studies reveal a therapeutic benefit of treatments targeting immune activation, suggesting that specific anti-inflammatory therapies could offer renewed hope for at least a subset of DGBI patients. Lastly, we explore the future directions for DGBI research that could advance the field. Taken together, emerging evidence supports the recognition of FD as an immune-mediated organic-based disorder, challenging the paradigm of a strictly functional nature.

Abstract
OBJECTIVE To evaluate the association of Jewish cultural and religious identity and denominational affiliation with interest in, intention to undertake and uptake of population-based BRCA (Breast Cancer Gene)-testing. DESIGN Cohort-study set within recruitment to GCaPPS-trial (ISRCTN73338115). SETTING London Ashkenazi-Jewish (AJ) population. POPULATION OR SAMPLE AJ men and women, >18 years. METHODS Participants were self-referred, and attended recruitment clinics (clusters) for pre-test counselling. Subsequently consenting individuals underwent BRCA testing. Participants self-identified to one Jewish denomination: Conservative/Liberal/Reform/Traditional/Orthodox/Unaffiliated. Validated scales measured Jewish Cultural-Identity (JI) and Jewish Religious-identity (JR). Four-item Likert-scales analysed initial 'interest' and 'intention to test' pre-counselling. Item-Response-Theory and graded-response models, modelled responses to JI and JR scales. Ordered/multinomial logistic regression modelling evaluated association of JI-scale, JR-scale and Jewish Denominational affiliation on interest, intention and uptake of BRCA testing. MAIN OUTCOME MEASURES Interest, intention, uptake of BRCA testing. RESULTS In all, 935 AJ women/men of mean age = 53.8 (S.D = 15.02) years, received pre-test education and counselling through 256 recruitment clinic clusters (median cluster size = 3). Denominational affiliations included Conservative/Masorti = 91 (10.2%); Liberal = 82 (9.2%), Reform = 135 (15.1%), Traditional = 212 (23.7%), Orthodox = 239 (26.7%); and Unaffiliated/Non-practising = 135 (15.1%). Overall BRCA testing uptake was 88%. Pre-counselling, 96% expressed interest and 60% intention to test. JI and JR scores were highest for Orthodox, followed by Conservative/Masorti, Traditional, Reform, Liberal and Unaffiliated Jewish denominations. Regression modelling showed no significant association between overall Jewish Cultural or Religious Identity with either interest, intention or uptake of BRCA testing. Interest, intention and uptake of BRCA testing was not significantly associated with denominational affiliation. CONCLUSIONS Jewish religious/cultural identity and denominational affiliation do not appear to influence interest, intention or uptake of population-based BRCA testing. BRCA testing was robust across all Jewish denominations. TWEETABLE ABSTRACT Jewish cultural/religious factors do not affect BRCA testing, with robust uptake seen across all denominational affiliations.

Abstract
Eosinophils are leukocytes which reside in the gastrointestinal tract under homeostatic conditions, except for the esophagus which is normally devoid of eosinophils. Research on eosinophils has primarily focused on anti-helminth responses and type 2 immune disorders. In contrast, the search for a role of eosinophils in chronic intestinal inflammation and fibrosis has been limited. With a shift in research focus from adaptive to innate immunity and the fact that the eosinophilic granules are filled with inflammatory mediators, eosinophils are becoming a point of interest in inflammatory bowel diseases. In the current review we summarize eosinophil characteristics and recruitment as well as the current knowledge on presence, inflammatory and pro-fibrotic functions of eosinophils in inflammatory bowel disease and other chronic inflammatory conditions, and we identify research gaps which should be covered in the future.

Abstract
Patients with Crohn disease (CD) and ulcerative colitis (UC) suffer from chronic relapsing intestinal inflammation. While many studies focused on adaptive immunity, less is known about the role of innate immune cells in these diseases. Innate lymphoid cells (ILCs) are recently identified cells with a high cytokine-producing capacity at mucosal barriers. The aim was to study the impact of biological treatment on ILC in CD and UC. Patients initiating anti–tumor necrosis factor (TNF), ustekinumab, or vedolizumab treatment were prospectively followed up and peripheral and intestinal ILCs were determined. In the inflamed gut tissue of patients with inflammatory bowel disease, we found an increase of ILC1 and in immature NKp44− ILC3, whereas there was a decrease of mature NKp44+ ILC3 when compared to healthy controls (HCs). Similar but less pronounced changes in ILC1 were observed in blood, whereas circulating NKp44− ILC3 were decreased. Fifteen percent of CD patients had NKp44+ ILC3 in blood and these cells were not detected in blood of HCs or UC patients. Therapy with three different biologicals (ustekinumab targeting the IL-12/23 cytokines, anti-TNF and vedolizumab) partly restored intestinal ILC subset equilibrium with a decrease of ILC1 (except for ustekinumab) and an increase of NKp44+ ILC3. Anti-TNF also mobilized more NKp44+ ILC3 in circulation. As ILC1 are proinflammatory cells and as NKp44+ ILC3 contribute to homeostasis of intestinal mucosa, the observed effects of biologicals on ILCs might contribute to their clinical efficacy.

Abstract
OBJECTIVE Estrogen is a well-established risk factor for various cancers. It causes endometrial proliferation, which is assessed routinely as endometrial thickness (ET) using transvaginal ultrasound (TVS). Only one previous study, restricted to endometrial and breast cancer, has considered ET and the risk of non-endometrial cancer. The aim of this study was to explore the association between baseline and serial ET measurements and nine non-endometrial hormone-sensitive cancers, in postmenopausal women, using contemporary statistical methodology that attempts to minimize the biases typical of endogenous serial data. METHODS This was a cohort study nested within the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS). In the ultrasound arm of UKCTOCS, 50639 postmenopausal women, aged 50-74, underwent annual TVS examination, of whom 38 105 had a valid ET measurement, no prior hysterectomy and complete covariate data, and were included in this study. All women were followed up through linkage to national cancer registries. The effect of ET on the risk of six estrogen-dependent cancers (breast, ovarian, colorectal, bladder, lung and pancreatic) was assessed using joint models for longitudinal biomarker and time-to-event data, and Cox models were used to assess the association between baseline ET measurement and these six cancers in addition to liver cancer, gastric cancer and non-Hodgkin's lymphoma (NHL). All models were adjusted for current hormone-replacement therapy (HRT) use, body mass index, age at last menstrual period, parity and oral contraceptive pill use. RESULTS The 38 105 included women had a combined total of 267 567 (median, 8; interquartile range, 5-9) valid ET measurements. During a combined total of 407 838 (median, 10.9) years of follow-up, 1398 breast, 351 endometrial, 381 lung, 495 colorectal, 222 ovarian, 94 pancreatic, 79 bladder, 62 gastric, 38 liver cancers and 52 NHLs were registered. Using joint models, a doubling of ET increased significantly the risk of breast (hazard ratio (HR), 1.21; 95% CI, 1.09-1.36; P = 0.001), ovarian (HR, 1.39; 95% CI, 1.06-1.82; P = 0.018) and lung (HR, 1.25; 95% CI, 1.02-1.54; P = 0.036) cancers. There were no statistically significant associations between ET and the remaining six cancers. CONCLUSION Postmenopausal women with high/increasing ET on TVS are at increased risk of breast, ovarian and lung cancer. It is important that clinicians are aware of these risks, as TVS is a common investigation. © 2019 The Authors.

Abstract
OBJECTIVE To evaluate factors affecting unselected population-based BRCA testing in Ashkenazi Jews (AJ). DESIGN Cohort-study set within recruitment to the GCaPPS trial (ISRCTN73338115). SETTING North London AJ population. POPULATION OR SAMPLE Ashkenazi Jews women/men >18 years, recruited through self-referral. METHODS Ashkenazi Jews women/men underwent pre-test counselling for BRCA testing through recruitment clinics (clusters). Consenting individuals provided blood samples for BRCA testing. Data were collected on socio-demographic/family history/knowledge/psychological well-being along with benefits/risks/cultural influences (18-item questionnaire measuring 'attitude'). Four-item Likert-scales analysed initial 'interest' and 'intention-to-test' pre-counselling. Uni- and multivariable logistic regression models evaluated factors affecting uptake/interest/intention to undergo BRCA testing. Statistical inference was based on cluster robust standard errors and joint Wald tests for significance. Item-Response Theory and graded-response models modelled responses to 18-item questionnaire. MAIN OUTCOME MEASURES Interest, intention, uptake, attitude towards BRCA testing. RESULTS A total of 935 individuals (women = 67%/men = 33%; mean age = 53.8 (SD = 15.02) years) underwent pre-test genetic-counselling. During the pre-counselling, 96% expressed interest in and 60% indicated a clear intention to undergo BRCA testing. Subsequently, 88% opted for BRCA testing. BRCA-related knowledge (P = 0.013) and degree-level education (P = 0.01) were positively and negatively (respectively) associated with intention-to-test. Being married/cohabiting had four-fold higher odds for BRCA testing uptake (P = 0.009). Perceived benefits were associated with higher pre-counselling odds for interest in and intention to undergo BRCA testing. Reduced uncertainty/reassurance were the most important factors contributing to decision-making. Increased importance/concern towards risks/limitations (confidentiality/insurance/emotional impact/inability to prevent cancer/marriage ability/ethnic focus/stigmatisation) were significantly associated with lower odds of uptake of BRCA testing, and discriminated between acceptors and decliners. Male gender/degree-level education (P = 0.001) had weaker correlations, whereas having children showed stronger (P = 0.005) associations with attitudes towards BRCA testing. CONCLUSIONS BRCA testing in the AJ population has high acceptability. Pre-test counselling increases awareness of disadvantages/limitations of BRCA testing, influencing final cost-benefit perception and decision-making on undergoing testing. TWEETABLE ABSTRACT BRCA testing in Ashkenazi Jews has high acceptability and uptake. Pre-test counselling facilitates informed decision-making.

Abstract
OBJECTIVE In the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS), self-reported visualization rate (VR) of the ovaries by the sonographer on annual transvaginal sonographic (TVS) examinations was a key quality control (QC) metric. The objective of this study was to assess self-reported VR using expert review of a random sample of archived images of TVS examinations from UKCTOCS, and then to develop software for measuring VR automatically. METHODS A single expert reviewed images archived from 1000 TVS examinations selected randomly from 68 931 TVS scans performed in UKCTOCS between 2008 and 2011 with ovaries reported as 'seen and normal'. Software was developed to identify the exact images used by the sonographer to measure the ovaries. This was achieved by measuring caliper dimensions in the image and matching them to those recorded by the sonographer. A logistic regression classifier to determine visualization was trained and validated using ovarian dimensions and visualization data reported by the expert. RESULTS The expert reviewer confirmed visualization of both ovaries (VR-Both) in 50.2% (502/1000) of the examinations. The software identified the measurement image in 534 exams, which were split 2:1:1 providing training, validation and test data. Classifier mean accuracy on validation data was 70.9% (95% CI, 70.0-71.8%). Analysis of test data (133 exams) provided a sensitivity of 90.5% (95% CI, 80.9-95.8%) and specificity of 47.5% (95% CI, 34.5-60.8%) in detecting expert confirmed visualization of both ovaries. CONCLUSIONS Our results suggest that, in a significant proportion of TVS annual screens, the sonographers may have mistaken other structures for normal ovaries. It is uncertain whether or not this affected the sensitivity and stage at detection of ovarian cancer in the ultrasound arm of UKCTOCS, but we conclude that QC metrics based on self-reported visualization of normal ovaries are unreliable. The classifier shows some potential for addressing this problem, though further research is needed. © 2017 The Authors.

Abstract
OBJECTIVES The negative publicity about menopausal hormone therapy (MHT) has led to increased use of complementary and alternative medicines (CAM) and non-pharmacological interventions (NPI) for menopausal symptom relief. We report on the prevalence and predictors of CAM/NPI among UK postmenopausal women. METHOD Postmenopausal women aged 50-74 years were invited to participate in the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS). A total of 202 638 women were recruited and completed a baseline questionnaire. Of these, 136 020 were sent a postal follow-up-questionnaire between September 2006 and May 2009 which included ever-use of CAM/NPI for menopausal symptom relief. Both questionnaires included MHT use. RESULTS A total of 88 430 (65.0%) women returned a completed follow-up-questionnaire; 22 206 (25.1%) reported ever-use of one or more CAM/NPI. Highest use was reported for herbal therapies (43.8%; 9725/22 206), vitamins (42.6%; 9458/22 206), lifestyle approaches (32.1%; 7137/22 206) and phytoestrogens (21.6%; 4802/22 206). Older women reported less ever-use of herbal therapies, vitamins and phytoestrogens. Lifestyle approaches, aromatherapy/reflexology/acupuncture and homeopathy were similar across age groups. Higher education, Black ethnicity, MHT or previous oral contraceptive pill use were associated with higher CAM/NPI use. Women assessed as being less hopeful about their future were less likely to use CAM/NPI. CONCLUSION One in four postmenopausal women reported ever-use of CAM therapies/NPI for menopausal symptom relief, with lower use reported by older women. Higher levels of education and previous MHT use were positive predictors of CAM/NPI use. UKCTOCS Trial registration: ISRCTN22488978.

Abstract
Abstract
Background: A number of proposed trastuzumab (TRAS) biosimilars are now in development for HER2-overexpressing breast cancer treatment. The purpose of this study was to systematically collate all published clinical data to assess the weight of available evidence for TRAS biosimilars in HER2-positive (+) breast cancer (BC), and to identify additional studies, not captured in the scientific literature, to support informed decision-making by healthcare stakeholders, as well as to raise awareness of ongoing developments within the field. Methods: MEDLINE®, Embase® and ISI Web of Science® were searched from inception to Sept 3, 2015. Conference proceedings (n=17) were searched from 2012 to Jul 31, 2015. Studies disclosing potential use of proposed biosimilars in the treatment of HER2+ BC were screened and categorized by originator and study type (English language only). To assess data strength and validity, risk of bias assessments were conducted. The ClinicalTrials.gov (CT.gov) registry was searched to identify any planned/ongoing/complete biosimilar trials in HER2+ BC. Results: On the analysis cut-off date, a total of 7 clinical studies (12 publications) were identified for proposed biosimilars of TRAS. The biosimilars identified for TRAS with published clinical data were BCD-022, CT-P6, FTMB and PF-05280014. For BCD-022, a pharmacokinetics (PK)/safety study in HER2+ BC (N=46) evaluating BCD-022 compared to TRAS, demonstrated equivalence between the two treatments. A PK/safety study (N=174) and comparative safety/efficacy study (N=475) of CT-P6 in HER2+ BC patients both provided evidence of PK equivalence, safety, and efficacy of the proposed biosimilar in this patient population. Bioequivalence of FTMB (versus TRAS) was also reported based on the results of a PK/safety study (N=118) in healthy subjects. For PF-05280014, a PK/safety study (N=105) in healthy volunteers demonstrated equivalence with TRAS. One published comparative safety/efficacy study protocol for PF-05280014 versus TRAS was identified for first-line treatment of patients with HER2+ BC (estimated [E]:N=690), and a second PK/efficacy/safety protocol for neoadjuvant BC treatment (E:N=220) was also published. A number of other planned studies were identified in CT.gov. These included 4 comparative safety/efficacy studies in HER2+ BC evaluating ABP 980 (E:N=808), CT-P6 (N=383/N=532), SB3 (E:N=806) and 2 PK/safety studies (BCD-022 [E:N=206], CT-P6 [E:N=174]) in women with BC. Two studies investigating PK and safety in healthy volunteers were also identified (PF-05280014 [E:N=162], SB3 [E:N=109]). Conclusions: This systematic review provides an unbiased synthesis of available evidence for proposed TRAS biosimilars in HER2+ BC, including data to support clinical similarity. The available clinical data for the 4 proposed biosimilars (BCD-022, CT-P6, FTMB and PF-05280014) investigated in a total of 918 healthy subjects or patients indicated highly comparable PK, safety, or efficacy profiles, versus TRAS. Additional data are required to fully evaluate the clinical similarity for proposed TRAS biosimilars, and the completion of several ongoing comparative trials are expected to provide further assurance of safety and efficacy in specific patient populations.

Abstract
Essentials The new recombinant factor IX (FIX) albumin fusion protein (rIX-FP) has a prolonged half-life. A population pharmacokinetic (PK) model was based on FIX activity levels of hemophilia B patients. The model was used to simulate different dosing scenarios of rIX-FP to help guide dosing. The population PK model supported prolonged dosing of rIX-FP with intervals of up to 2 weeks. Click to hear Prof.Makris's presentation on new treatments in hemophilia SUMMARY: Background The recombinant fusion protein linking recombinant coagulation factor IX with recombinant albumin (rIX-FP; Idelvion® ) exhibits a longer half-life than plasma-derived factor IX (FIX) and the commercially available recombinant FIX products. Objectives (i) Characterize the population pharmacokinetics (PK) of rIX-FP in hemophilia B patients, (ii) identify covariates that are potential determinants of rIX-FP PK variability and (iii) simulate different dosing scenarios of rIX-FP following single and steady-state dosing. Patients/Methods A population PK model was developed based on FIX activity levels of 104 patients who had received treatment with rIX-FP. Patients were aged 1-65 years with FIX activity ≤ 2 IU dL-1 . PK sampling was performed for up to 14 days (336 h). Results Simulation of a single intravenous infusion of rIX-FP (25-75 IU kg-1 ) predicted that the median trough exogenous FIX activity levels would remain > 5 IU dL-1 for up to 16 days in adolescents/adults aged ≥ 12 years, up to 12 days in children aged 6 to < 12 years, and up to 9.5 days in children aged < 6 years. For steady-state dosing, the median trough exogenous FIX activity levels were maintained at > 5 IU dL-1 for the duration of the dosing interval for the 25, 35 and 40 IU kg-1 weekly regimens and for 75 IU kg-1 every 14 days in adolescents/adults, and for the 35 and 40 IU kg-1 weekly regimens in children. Conclusion The population PK model developed here correlates well with observed clinical data and supports prolonged dosing of rIX-FP with intervals of up to 2 weeks.

Abstract
Noninvasive preclinical methods for the characterization of myocardial vascular function are crucial to an understanding of the dynamics of ischemic cardiac disease. Ischemic heart disease is associated with myocardial endothelial dysfunction, resulting in leakage of plasma albumin into the extravascular space. These features can be harnessed in a novel noninvasive three-dimensional magnetic resonance imaging method to measure fractional blood volume (fBV) and vascular permeability (permeability-surface area product, PS) using labeled albumin as a blood pool contrast agent. C57BL/6 mice were imaged before and 3 days after myocardial infarction (MI). Following the quantification of endogenous myocardial R1 , the dynamics of intravenously injected albumin-based contrast agent, extravasating from permeable myocardial blood vessels, were tracked on short-axis magnetic resonance images of the entire heart. This study successfully discriminated between infarcted and remote regions at 3 days post-infarct, based on a reduced fBV and increased PS in the infarcted region. These findings were confirmed using ex vivo fluorescence imaging and histology. We have demonstrated a novel method to quantify blood volume and permeability in the infarcted myocardium, providing an imaging biomarker for the assessment of endothelial dysfunction. This method has the potential to three-dimensionally visualize subtle changes in myocardial permeability and to track endothelial function for longitudinal cardiac studies determining pathophysiological processes during infarct healing.

Abstract
OBJECTIVE To compare time to diagnosis of the typically slow-growing Type I (low-grade serous, low-grade endometrioid, mucinous, clear cell) and the more aggressive Type II (high-grade serous, high-grade endometrioid, undifferentiated, carcinosarcoma) invasive epithelial ovarian cancer (iEOC). DESIGN Multicentre observational study. SETTING Ten UK gynaecological oncology centres. POPULATION Women diagnosed with primary EOC between 2006 and 2008. METHODS Symptom data were collected before diagnosis using patient questionnaire and primary-care records. We estimated patient interval (first symptom to presentation) using questionnaire data and diagnostic interval (presentation to diagnosis) using primary-care records. We considered the impact of first symptom, referral and stage on intervals for Type I and Type II iEOC. MAIN OUTCOME MEASURES Patient and diagnostic intervals. RESULTS In all, 78% of 60 Type I and 21% of 134 Type II iEOC were early-stage. Intervals were comparable and independent of stage [e.g. median patient interval for Type I: early-stage 0.3 months (interquartile range 0.3-3.0) versus late-stage 0.3 months (interquartile range 0.3-4.5), P = 0.8]. Twenty-seven percent of women with Type I and Type II had diagnostic intervals of at least 9 months. First symptom (questionnaire) was also similar, except for the infrequent abnormal bleeding (Type I 15% versus Type II 4%, P = 0.01). More women with Type I disease (57% versus 41%, P = 0.04) had been referred for suspected gynaecological cancer. Median time from referral to diagnosis was 1.4 months for women with iEOC referred via a 2-week cancer referral to any specialty compared with 2.6 months (interquartile range 2.0-3.7) for women who were referred routinely to gynaecology. CONCLUSION Overall, shorter diagnostic delays were seen when a cancer was suspected, even if the primary tumour site was not recognised to be ovarian. Despite differences in carcinogenesis and stage for Type I and Type II iEOC, time to diagnosis and symptoms were similar. Referral patterns were different, implying subtle symptom differences. If symptom-based interventions are to impact on ovarian cancer survival, it is likely to be through reduced volume rather than stage-shift. Further research on histological subtypes is needed. TWEETABLE ABSTRACT No difference in time to diagnosis for Type I versus Type II invasive epithelial ovarian cancers.

Abstract
OBJECTIVE To describe the quality assurance (QA) processes and their impact on visualization of postmenopausal ovaries in the ultrasound arm of a multicenter screening trial for ovarian cancer. METHODS In the United Kingdom Collaborative Trial of Ovarian Cancer Screening, 50 639 women aged 50-74 years were randomized to the ultrasound arm and underwent annual transvaginal ultrasound (TVS) examinations. QA processes were developed during the course of the trial and included regular monitoring of the visualization rate (VR) of the right ovary. Non-subjective factors identified previously as impacting on VR of the right ovary were included in a generalized estimating equation model for binary outcomes to enable comparison of observed vs adjusted VR between individual sonographers who had undertaken > 1000 scans during the trial and comparison between centers. Observed and adjusted VRs of sonographers and centers were ranked according to the highest VR. Analysis of annual VRs of sonographers and those of the included centers was undertaken. RESULTS Between June 2001 and December 2010, 48 230 of 50 639 women attended one of 13 centers for a total of 270 035 annual TVS scans. One or both ovaries were seen in 228 145 (84.5%) TVS scans. The right ovary was seen on 196 426 (72.7%) of the scans. For the 78 sonographers included in the model, the median difference between observed and adjusted VR was -0.7% (range, -7.9 to 5.9%) and the median change in VR rank after adjustment was 3 (range, 0-18). For the 13 centers, the median difference between observed and adjusted VR was -0.5% (range, -2.2 to 1%), with no change in ranking after adjustment. The median adjusted VR was 73% (interquartile range (IQR), 65-82%) for sonographers and 74.7% (IQR, 67.1-79.0%) for centers. Despite the increasing age of the women being scanned, there was a steady decrease in the number of sonographers with VR < 60% (21.4% in 2002 vs 2.0% in 2010) and an increase in sonographers with VR > 80% (14.3% in 2002 vs 40.8% in 2010). The median VR of the centers increased from 65.5% (range, 55.7-81.0%) in 2001 to 80.3% (range, 74.5-90.9%) in 2010. CONCLUSIONS A robust QA program can improve visualization of postmenopausal ovaries and is an essential component of ultrasound-based ovarian cancer screening trials. While VR should be adjusted for non-subjective factors that impact on ovarian visualization, subjective factors are likely to be the largest contributors to differences in VR.

Abstract
Background: Blood-borne biomarkers for early detection of colorectal cancer (CRC) could markedly increase screening uptake. The aim of this study was to evaluate serum carcinoembryonic antigen (CEA), CYFRA21-1 and CA125 for the early detection of CRC in an asymptomatic cohort. Methods: This nested case–control study within UKCTOCS used 381 serial serum samples from 40 women subsequently diagnosed with CRC, 20 women subsequently diagnosed with benign disease and 40 matched non-cancer controls with three to four samples per subject taken annually up to 4 years before diagnosis. CEA, CYFRA21-1 and CA125 were measured using validated assays and performance of markers evaluated for different pre-diagnosis time groups. Results: CEA levels increased towards diagnosis in a third of all cases (half of late-stage cases), whereas longitudinal profiles were static in both benign and non-cancer controls. At a threshold of >5 ng ml−1 the sensitivities for detecting CRC up to 1 and 4 years before clinical presentation were 25% and 13%, respectively, at 95% specificity. At a threshold of >2.5 ng ml−1, sensitivities were 57.5% and 38.4%, respectively, with specificities of 81% and 83.5%. CYFRA21-1 and CA125 had no utility as screening markers and did not enhance CEA performance when used in combination. CEA gave average lead times of 17–24 months for test-positive cases. Conclusions: CEA is elevated in a significant proportion of individuals with preclinical CRC, but would not be useful alone as a screening tool. This work sets a baseline from which to develop panels of biomarkers which combine CEA for improved early detection of CRC.

Abstract
Introduction rIX-FP is a coagulation factor IX (recombinant), albumin fusion protein with more than fivefold half-life prolongation over other standard factor IX (FIX) products available on the market. Aim This prospective phase II, open-label study evaluated the safety and efficacy of rIX-FP for the prevention of bleeding episodes during weekly prophylaxis and assessed the haemostatic efficacy for on-demand treatment of bleeding episodes in previously treated patients with haemophilia B. Methods The study consisted of a 10–14 day evaluation of rIX-FP pharmacokinetics (PK), and an 11 month safety and efficacy evaluation period with subjects receiving weekly prophylaxis treatment. Safety was evaluated by the occurrence of related adverse events, and immunogenic events, including development of inhibitors. Efficacy was evaluated by annualized spontaneous bleeding rate (AsBR), and the number of injections to achieve haemostasis. Results Seventeen subjects participated in the study, 13 received weekly prophylaxis and 4 received episodic treatment only. No inhibitors were detected in any subject. The mean and median AsBR were 1.25, and 1.13 respectively in the weekly prophylaxis arm. All bleeding episodes were treated with 1 or 2 injections of rIX-FP. Three prophylaxis subjects who were treated on demand prior to study entry had >85% reduction in AsBR compared to the bleeding rate prior to study entry. Conclusion This study demonstrated the efficacy for weekly routine prophylaxis of rIX-FP to prevent spontaneous bleeding episodes and for the treatment of bleeding episodes. In addition no safety issues were detected during the study and an improved PK profile was demonstrated.

Abstract
Circulating intercellular adhesion molecule-1 (ICAM-1) and tissue inhibitor of metalloproteinases-1 (TIMP-1) have been widely proposed as potential diagnostic biomarkers for pancreatic ductal adenocarcinoma (PDAC). We report on serum protein levels prior to clinical presentation of pancreatic cancer. Serum ICAM-1 and TIMP-1 were measured by ELISA in two case–control sets: 1) samples from patients diagnosed with pancreatic cancer (n = 40), chronic pancreatitis (n = 20), benign jaundice due to gall stones (n = 20) and healthy subjects (n = 20); 2) a preclinical set from the UK Collaborative Trial of Ovarian Cancer Screening biobank of samples collected from 27 post-menopausal women 0–12 months prior to diagnosis of pancreatic cancer and controls matched for date of donation and centre. Levels of ICAM-1 and TIMP-1 were significantly elevated in set 1 in PDAC patients with jaundice compared to PDAC patients without jaundice and both proteins were elevated in patients with jaundice due to gall stones. Neither protein was elevated in samples taken 0–12 months prior to PDAC diagnosis compared to non-cancer control samples. In conclusion, evaluation in pre-diagnosis samples discounts ICAM-1 and TIMP-1 as biomarkers for earlier diagnosis of pancreatic cancer. Failure to account for obstructive jaundice may have contributed to the previous promise of these candidate biomarkers. BIOLOGICAL SIGNIFICANCE Pancreatic cancer is usually diagnosed when at an advanced stage which greatly limits therapeutic options. Biomarkers that could facilitate earlier diagnosis are urgently sought.

Background: PF05280014 is being developed as a potential biosimilar to trastuzumab. PF-05280014 demonstrated similarity to trastuzumab in nonclinical evaluations. In a Phase I trial in healthy volunteers, PF-05280014 pharmacokinetic characteristics and safety profile were shown to be similar to those of trastuzumab. The goal of this Phase 3 trial is to demonstrate that the efficacy and safety of PF-05280014 + paclitaxel are similar to those of trastuzumab sourced from the EU (trastuzumab-EU) + paclitaxel in women with HER2-positive metastatic breast cancer.
Trial design: In this randomized, double-blind trial, patients will be randomized 1:1 into 2 arms: PF-05280014 + paclitaxel and trastuzumab-EU + paclitaxel. Randomization will be stratified by prior adjuvant trastuzumab exposure and estrogen receptor status. The order of infusion will be PF-05280014 or trastuzumab (4 mg/kg in Cycle 1; 2 mg/kg thereafter over 90 min) first followed by paclitaxel (80 mg/m2).
Eligibility: Female patients, aged ≥18 y with confirmed HER-2 overexpressing metastatic breast cancer, ≥1measurable lesion (RECIST), Eastern Cooperative Oncology Group status 0–2, normal left ventricular ejection fraction, and normal laboratory values are eligible. Key exclusion criteria are prior systemic therapy for metastatic disease, prior cumulative dose of anthracyclines >400 mg/m2, and major surgery, radiotherapy or investigational agents within 4 weeks. All subjects must provide informed consent.
Aims: The primary objective is to demonstrate the similarity in objective response rate (ORR) of PF-05280014 + paclitaxel treatment to that of trastuzumab-EU + paclitaxel. Secondary objectives include evaluating 1-year progression-free survival, safety, pharmacokinetics, and immunogenicity of these combination treatments.
Statistical methods: This study tests whether the ORR of PF-05280014 is similar to that of trastuzumab-EU, using a margin of 13%, i.e., 5% alpha for non-inferiority. Assuming 60% ORR in both arms, 600 patients (300/arm) will be needed to achieve 90% power. Assuming 10% attrition, a total of 660 patients will be randomized. The intent-to-treat (ITT) population is defined as all subjects who are randomized to receive treatment. The per-protocol population is defined as all subjects who are randomized to and receive treatment and do not have any major protocol violations and will be used for evaluation efficacy endpoints.
Accrual: The target accrual of this global trial is 660 patients.

Abstract
OBJECTIVE Transvaginal sonography (TVS) is core to any ovarian cancer screening strategy. General-population screening involves older postmenopausal women in whom ovarian visualization is difficult because of decreasing ovarian size and lack of follicular activity. We report on factors affecting the visualization of postmenopausal ovaries in the multicenter United Kingdom Collaborative Trial of Ovarian Cancer Screening (UKCTOCS). METHODS The UKCTOCS is a randomized controlled trial of 202 638 postmenopausal women with 50 639 women in the ultrasound scan arm. TVS is the primary screening modality in the ultrasound scan arm. Age, education, ethnicity, body mass index (BMI), previous pelvic surgery, lifestyle and reproductive factors, and a personal/family history of cancer were assessed for their effects on ovarian visualization at the initial TVS. RESULTS Between 11 June 2001 and 18 August 2007, 43 867 women underwent TVS. The median age and BMI of the women were 60.6 (interquartile range (IQR), 9.9) years and 25.7 (IQR, 5.8), respectively. The right ovary was visualized in 29 297 (66.8%) and the left ovary was visualized in 28 726 (65.5%). Visualization of ovaries decreased with previous hysterectomy (odds ratio (OR) = 0.534; 95% CI, 0.504-0.567), previous tubal ligation (OR = 0.895; 95% CI, 0.852-0.940), increasing age (OR = 0.953; 95% CI, 0.950-0.956), unilateral oophorectomy (OR = 0.224; 95% CI, 0.186-0.269) and being overweight (OR = 0.918; 95% CI, 0.876-0.962) or obese (OR = 0.715; 95% CI, 0.677-0.755). Increased visualization was observed with a history of infertility (OR = 1.134; 95% CI, 1.005-1.279) and increasing age (in years) at menopause (OR = 1.005; 95% CI, 1.001-1.009). CONCLUSIONS Several factors affect the visualization of postmenopausal ovaries. Their impact needs to be taken into consideration when developing quality assurance for ovarian ultrasound scanning or comparing study results as their prevalence may differ between populations.

Abstract
BACKGROUND Although laparoscopic intra-peritoneal mesh repair (LVHR) is a well-established treatment option to repair ventral and incisional hernias, no consensus in the literature can be found on the best method of fixation of the mesh to the abdominal wall. METHODS Between December 2004 and July 2008, 76 patients undergoing a LVHR were randomized between mesh fixation using a double row of spiral tackers (DC) (n = 33) and mesh fixation with transfascial sutures combined with one row of spiral tackers (S&T) (n = 43), in the WoW trial (with or without sutures). Patients were clinically examined and evaluated using a visual analog scale for pain (VAS) in rest and after coughing 4 h post-operatively, after 4 weeks and 3 months after surgery. Primary endpoint of the study was abdominal wall pain, defined as a VAS score of at least 1.0 cm, at 3 months post-operative. Quality of life was quantified with the SF-36 questionnaire preoperatively and after 3 months. Secondary endpoint was the recurrence rate at 24-month follow-up. RESULTS The DC and S&T group were comparable in age, gender, ASA score, BMI, indication, hernia, and mesh variables. The DC group had a significant shorter operating time compared with the S&T group (74 vs 96 min; p = 0.014) and a significant lower mean VAS score 4 h post-operatively (in rest; p = 0.028/coughing; p = 0.013). At 3 months, there were significant more patients in the S&T group with VAS score ≥1.0 cm (31.4 vs 8.3 %; p = 0.036). Clinical follow-up at 24 months was obtained in 63 patients (82.9 %). The recurrence rate at 24 months was 7.9 % overall (5/63). There were more recurrences in the S&T group (4/36) than in the DC group (1/27), but this difference was not significant (11.1 vs 3.7 %; p = 0.381). CONCLUSION We found that double-crown fixation of intra-peritoneal mesh during laparoscopic ventral hernia repair was quicker, was less painful immediately post-operative and after 3 months, and did not increase the recurrence rate at 24 months. In hernias at a distance from the bony borders of the abdomen, transfascial sutures can be omitted if a double crown of tackers is placed.

Abstract
OBJECTIVE To assess pain and overall experience of transvaginal sonography (TVS) in asymptomatic postmenopausal women. METHODS In the United Kingdom Collaborative Trial of Ovarian Cancer Screening (UKCTOCS), 50 639 postmenopausal women were randomized to undergo annual TVS at 13 trial centers in England, Wales and Northern Ireland. Together with the appointment letter for their annual scan, a random sample of 150 women per center was sent a detailed 48-item postal questionnaire regarding the screening experience. It included a specific question about pain using a score of 0-5, where 5 was severe pain and 3 was discomfort. To assess factors that might affect a woman's reported pain experience, the pain score was regressed on age, hormone replacement therapy use, body mass index, a history of hysterectomy, prolonged scanning time, ovarian visualization, scan result, sonographer's visualization rates and opinion of the women regarding the sonographer who performed the scan. RESULTS Between 7 July and 9 September 2009, 1950 randomly chosen women (150 per regional center) were sent the questionnaire. Of the 800 (41.0%) who returned the questionnaire, 651 could be linked to their TVS appointment. One-hundred and fifty-two (23.3%) women reported pain/discomfort (score 3-5) during TVS and 473 (72.7%) reported no discomfort (score 0-2). Only 23 (3.5%) women reported experiencing moderate/severe pain. Increasing discomfort/pain was independently associated with a history of hysterectomy and participant's reporting of prolonged scan time. Women who experienced pain on TVS were less compliant (odds ratio = 0.87) with the following year's scan compared with those who did not experience pain. CONCLUSIONS The majority of postmenopausal women found TVS acceptable. Pain influenced compliance and correlated with women's perception of increased scanning time and previous hysterectomy.

Abstract
Background: Recent reports from cancer screening trials in high-risk populations suggest that autoantibodies can be detected before clinical diagnosis. However, there is minimal data on the role of autoantibody signatures in cancer screening in the general population. Methods: Informative p53 peptides were identified in sera from patients with colorectal cancer using an autoantibody microarray with 15-mer overlapping peptides covering the complete p53 sequence. The selected peptides were evaluated in a blinded case–control study using stored serum from the multimodal arm of the United Kingdom Collaborative Trial of Ovarian Cancer Screening where women gave annual blood samples. Cases were postmenopausal women who developed colorectal cancer following recruitment, with 2 or more serum samples preceding diagnosis. Controls were age-matched women with no history of cancer. Results: The 50 640 women randomised to the multimodal group were followed up for a median of 6.8 (inter-quartile range 5.9–8.4) years. Colorectal cancer notification was received in 101 women with serial samples of whom 97 (297 samples) had given consent for secondary studies. They were matched 1 : 1 with 97 controls (296 serial samples). The four most informative peptides identified 25.8% of colorectal cancer patients with a specificity of 95%. The median lead time was 1.4 (range 0.12–3.8) years before clinical diagnosis. Conclusion: Our findings suggest that in the general population, autoantibody signatures are detectable during preclinical disease and may be of value in cancer screening. In colorectal cancer screening in particular, where the current need is to improve compliance, it suggests that p53 autoantibodies may contribute towards risk stratification.

Abstract
OBJECTIVE To estimate the risk of primary epithelial ovarian cancer (EOC) and slow growing borderline or Type I and aggressive Type II EOC in postmenopausal women with adnexal abnormalities on ultrasound. METHODS This was a prospective cohort study in the ultrasound group of the UK Collaborative Trial of Ovarian Cancer Screening of postmenopausal women with ultrasound-detected abnormal adnexal (unilocular, multilocular, unilocular solid and multilocular solid, solid) morphology on their first scan. Women were followed up through the national cancer registries and by postal questionnaires. Absolute risks of EOC and borderline, Type I and Type II EOC within 3 years of initial scan were calculated. RESULTS Of 48 053 women who underwent ultrasound examination and had complete scan data, 4367 (9.1% (95% CI, 8.8-9.3%)) had abnormal adnexal morphology. Median follow-up was 7.09 (25(th) -75(th) centiles, 6.03-7.92) years. Forty-seven (32 borderline or Type I, 15 Type II) were diagnosed with EOC. The overall absolute risk of EOC associated with abnormal adnexal morphology was 1.08% (95% CI, 0.79-1.43%); for borderline and Type I it was 0.73% (95% CI, 0.5-1.03%); and for Type II it was 0.34% (95% CI, 0.33-0.79%). In the subgroup (n = 741) with solid elements (unilocular solid, multilocular solid and solid) overall absolute risk was 4.45% (95% CI, 3.08-6.20%), for borderline and Type I it was 3.1% (95% CI, 1.9-4.6%) and for Type II it was 1.3% (95% CI, 0.6-2.4%). 11 982 women had both ovaries visualized and normal annual scans throughout the 3-year follow-up period. In this group, no borderline or Type I and eight Type II cancers were diagnosed. CONCLUSION Asymptomatic postmenopausal women with ultrasound-detected adnexal abnormalities with solid elements have a 1 in 22 risk for EOC. Despite the higher prevalence of Type II EOC, the risk of borderline or Type I cancer in women with ultrasound abnormalities seems to be higher than does the risk of Type II cancer. This has important immediate implications for patients with incidental adnexal findings as well as for any future ultrasound-based screening.

Abstract
BACKGROUND In research studies, accurate information of cancer diagnosis is crucial. In women with breast cancer (BC), we compare cancer registration (CR) in England/Wales and self-reporting with independent confirmation. METHODS In the UK Collaborative Trial of Ovarian Cancer Screening, notification of BC diagnosed between randomisation and 31 December 2009 was obtained through (1) CR (17 October 2011) and (2) self-reporting using postal-questionnaire. Breast cancer was confirmed using a detailed questionnaire (BC questionnaire BCQ) completed by the treating clinician (gold standard). Apparent sensitivity and positive-predictive value of CR/self-reporting vs BCQ were calculated. RESULTS Of 1065 women with possible BC notification, diagnosis was confirmed in 932 (87.5%). A total of 3.1% (28 out of 918) of BC CR and 12.4% (128 out of 1032) of women with self-reported BC only had in-situ carcinoma on BCQ. Another 4.6% (43 out of 932) of BCQ-confirmed cancer did not have a BC registration, and 3.6% (34 out of 932) did not self-report BC. Apparent sensitivity of CR and self-reporting vs BCQ were 95.4 and 96.4%, respectively. Positive-predictive value of self-reporting (87.1%) was significantly lower than that of CR (96.8%). Women aged<65 were more likely to over report in-situ carcinoma as BC. Overall, 73 (6.8%) women would have been misclassified/missed if CR, and 167 (15.6%) if self-reporting data alone was used. CONCLUSION This study confirms the reliability of BC registration in England/Wales and highlights the fact that 1 in 10 women self-reporting BC might only have in-situ breast carcinoma.

Abstract
OBJECTIVE To evaluate factors affecting uptake of risk-reducing salpingo-oophorectomy (RRSO) over time in women at high-risk of familial ovarian cancer. DESIGN Prospective observational cohort. SETTING Tertiary high-risk familial gynaecological cancer clinic. POPULATION/SAMPLE New clinic attendees between March 2004 and November 2009, fulfilling the high-risk criteria for the UK Familial Ovarian Cancer Screening Study. METHODS Risk management options discussed included RRSO and ovarian surveillance. Outcome data were analysed from a bespoke database. The competing risk method was used to model the cumulative incidence function (CIF) of RRSO over time, and the sub-hazard ratio (SHR) was used to assess the strength of the association of variables of interest with RRSO. Gray's test was used to evaluate the difference in CIF between two groups and multivariable competing risk regression analysis was used to model the cumulative probabilities of covariates on the CIF. RESULTS Of 1133 eligible women, 265 (21.4%) opted for RRSO and 868 (69.9%) chose screening. Women undergoing RRSO were older (49 years, interquartile range 12.2 years) than those preferring screening (43.4 years, interquartile range 11.9 years) (P < 0.0005). The CIF for RRSO at 5 years was 0.55 (95% CI 0.45-0.64) for BRCA1/2 carriers and 0.22 (95% CI 0.19-0.26) for women of unknown mutation status (P < 0.0001); 0.42 (95% CI 0.36-0.47) for postmenopausal women (P < 0.0001); 0.29 (95% CI 0.25-0.33) for parity ≥1 (P = 0.009) and 0.47 (95% CI 0.39-0.55) for a personal history of breast cancer (P < 0.0001). Variables of significance from the regression analysis were: a BRCA1/2 mutation (SHR 2.31, 95% CI 1.7-3.14), postmenopausal status (SHR 2.16, 95% CI 1.62-2.87)) and a personal history of breast cancer (SHR 1.5, 95% CI 1.09-2.06). CONCLUSIONS Decision-making is a complex process and women opt for surgery many years after initial risk assessment. BRCA carriers, postmenopausal women and women who had breast cancer are significantly more likely to opt for preventative surgery.

Abstract
OBJECTIVE Hot flushes and night sweats (HFs/NSs) are the main menopausal symptoms, but few studies have been adequately powered to examine the dimensions or predictors of experiencing HFs/NSs. We report on these variables in a large UK cohort of postmenopausal women. DESIGN Cross-sectional cohort study. SETTING UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) cohort. POPULATION A cohort of 202,638 postmenopausal women, aged 50-74 years, without oophorectomy, recruited to UKCTOCS between 2001 and 2005. METHODS Women completed a follow-up questionnaire, and those aged 54-65 years were mailed a survey in July 2008. MAIN OUTCOME MEASURES Hot flush prevalence and hot flush rating scale. RESULTS Of the 15,000 women mailed, 10,418 returned completed questionnaires; 90% had previously had HFs/NSs. Despite being on average 10 years postmenopausal, 54% experienced HFs/NSs (frequency of 33 per week with mean problem rating 4/10) that persisted across the age range. Past hysterectomy (OR 1.50, 95% CI 1.19-1.86), ever having smoked (OR 1.27, 95% CI 1.11-1.46) and alcohol consumption (current units) (OR 1.05, 95% CI 1.01-1.09) predicted ever having had HFs/NSs. Anxiety (OR 3.09, 95% CI 2.57-3.72), hysterectomy (OR 2.74, 95% CI 2.32-3.25), depressed mood (OR 1.57, 95% CI 1.24-1.99), years since last menstrual period (OR 0.95, 95% CI 0.94-0.96) and education (above and below 18 years) (OR 0.98, 95% CI 0.97-0.99) predicted the current prevalence of HFs/NSs. Few predictors of frequency were identified, but problem rating was associated with depressed mood, hysterectomy, skirt size increase and frequency of HFs/NSs. Past hormone therapy users who had discontinued treatment were more likely to have HFs/NSs that were more frequent and problematic. CONCLUSIONS To date, this is the largest UK study of the experience of HFs/NSs amongst older postmenopausal women. HFs/NSs are more prevalent in this age band than has previously been assumed. These findings and the associations of smoking, hysterectomy, anxiety, depressed mood and hormone therapy use with the experience of HFs/NSs have implications for prevention and symptom management.

Abstract
OBJECTIVE To evaluate the malignant potential of ultrasound-detected ovarian inclusion cysts in the development of ovarian cancer (OC) in postmenopausal women. DESIGN Prospective cohort study. SETTING UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS). POPULATION Postmenopausal women. METHODS In UKCTOCS, women in the ultrasound group have annual scans. Women with inclusion cysts (single/multiple anechoic ≤10-mm ovarian cysts) and normal ovaries (both uniform hypoechogenicity) on their first scan were identified and followed up through cancer registry/questionnaires. MAIN OUTCOME MEASURES Relative risk (RR) of developing OC, invasive epithelial ovarian cancer (iEOC), breast cancer (BC) and endometrial cancer (EC) in women with inclusion cysts relative to those with normal ovaries. The incidence was compared with UK age-adjusted expected rates (Office for National Statistics, 2005). RESULTS Postmenopausal women (n = 48,230) attended the year 1 (11 June 2001-6 December 2006) screen; 1234 (2.5%) had inclusion cysts alone and 22,914 had normal scans. By 1 November 2009 (median follow-up, 6.13 years; interquartile range, 4.96-6.98 years), four, three (one Type II), seven and 22 women with inclusion cysts and 32, 29 (20 Type II), 90 and 397 women with normal ovaries were diagnosed with OC, iEOC, EC and BC, respectively. The RR values for the respective cancers (OC [RR, 2.32; confidence interval [CI], 0.86-6.28], iEOC [RR, 1.92; CI, 0.62-5.92], EC [RR, 1.44; CI, 0.68-3.05], BC [RR, 1.12; CI, 0.73-1.73]) were not increased. There was no difference between the observed versus expected incidence rates for these cancers in women with inclusion cysts. CONCLUSIONS Postmenopausal women with ultrasound-detected inclusion cysts do not seem to be at increased risk of ovarian or breast/endometrial (hormone-dependent) cancers.

Abstract
The purpose of this study is to measure the impact of a multidisciplinary one-stop follow-up clinic (MDOSC) on breast and ovarian surveillance, risk reducing surgery and enrolment in clinical trials in BRCA1/2 carriers. All BRCA1/2 carriers in our region were invited and chose which specialists to see in our MDOSC offering best practice using clinical protocols based on national guidelines and published data. Uptake was evaluated over 24 months recording numbers of individuals undergoing breast and ovarian surveillance, risk reducing surgery, newly diagnosed cancers, their method of detection and participation in clinical trials. 172 (60%) of invited BRCA1/2 carriers chose to attend the MDOSC. Breast surveillance was initiated in 88% and screening frequency altered in 14% of women to comply with national guidelines. Risk reducing salpingo-oophorectomy was chosen by 47% of women and an additional 39% were considering it. The rate of failure to remove fallopian tubes fell from 15 to 3% of procedures (P < 0.01) and peritoneal washings and serial sectioning of tubes and ovaries rose from 25% and 14% before, to 67% (P < 0.001) and 63% (P < 0.001) procedures, respectively, after initiation of our MDOSC. 24% of women considered and 18% decided to undergo risk reducing mastectomy during the follow-up period. Participation in clinical trials increased significantly from 51 to 229 enrolments (P < 0.001). Our novel MDOSC designed to devise an individually tailored cancer risk management strategy had a high uptake amongst our BRCA1/2 carriers. Attendance resulted in improved breast and ovarian cancer risk management.
