Abstract
Background Ovarian cancer (OC) remains the deadliest gynecologic malignancy worldwide due to delayed diagnosis, recurrence, and drug resistance. This study aimed to identify key factors affecting delayed diagnosis in OC patients. Methods A retrospective analysis was conducted on OC patients treated at Taihe Hospital, Hubei University of Medicine from June 2023 to September 2023. Patients were categorized based on a three-months cut-off point for delayed diagnosis. Collected data included demographics, tumor incidence, and disease cognition. The analysis of variance and the chi-squared test was used for comparison between groups. Results The significant differences were found in age, residence, education level, family income, family history of tumor, histology, FIGO stage, and tumor location between groups (P<0.05). Multifactorial logistic regression analysis identified education level [odds ratio (OR) = 0.606; 95% confidence interval (CI): 0.440, 0.833; P = 0.002], family history of tumor (OR = 0.462; 95% CI: 0.214, 0.997; P = 0.049), emotional barriers (OR = 1.332; 95% CI: 1.081, 1.642; P = 0.007), and practical barriers (OR = 2.964; 95% CI: 2.195, 4.004; P < 0.001) as risk factors for delayed diagnosis of OC. Conclusion Patient cognition is crucial in OC diagnosis delay. Enhancing public awareness and understanding of OC is essential to eliminate fear and improve early diagnosis.

BJOG 2024; 131:1400-1410. [PMID: 38556698 PMCID: PMC7616335 DOI: 10.1111/1471-0528.17813] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 02/29/2024] [Accepted: 03/04/2024] [Indexed: 04/02/2024]
Abstract
OBJECTIVE To investigate psychological correlates in women referred with suspected ovarian cancer via the fast-track pathway, explore how anxiety and distress levels change at 12 months post-testing, and report cancer conversion rates by age and referral pathway. DESIGN Single-arm prospective cohort study. SETTING Multicentre. Secondary care including outpatient clinics and emergency admissions. POPULATION A cohort of 2596 newly presenting symptomatic women with a raised CA125 level, abnormal imaging or both. METHODS Women completed anxiety and distress questionnaires at recruitment and at 12 months for those who had not undergone surgery or a biopsy within 3 months of recruitment. MAIN OUTCOME MEASURES Anxiety and distress levels measured using a six-item short form of the State-Trait Anxiety Inventory (STAI-6) and the Impact of Event Scale - Revised (IES-r) questionnaire. Ovarian cancer (OC) conversion rates by age, menopausal status and referral pathway. RESULTS Overall, 1355/2596 (52.1%) and 1781/2596 (68.6%) experienced moderate-to-severe distress and anxiety, respectively, at recruitment. Younger age and emergency presentations had higher distress levels. The clinical category for anxiety and distress remained unchanged/worsened in 76% of respondents at 12 months, despite a non-cancer diagnosis. The OC rates by age were 1.6% (95% CI 0.5%-5.9%) for age <40 years and 10.9% (95% CI 8.7%-13.6%) for age ≥40 years. In women referred through fast-track pathways, 3.3% (95% CI 1.9%-5.7%) of pre- and 18.5% (95% CI 16.1%-21.0%) of postmenopausal women were diagnosed with OC. CONCLUSIONS Women undergoing diagnostic testing display severe anxiety and distress. Younger women are especially vulnerable and should be targeted for support. Women under the age of 40 years have low conversion rates and we advocate reducing testing in this group to reduce the harms of testing.

Abstract
Pre-surgical clinical assessment of an adnexal mass is a complex process, and ideally requires accurate and rapid identification of disease status. Gold standard biomarker CA125 is extensively used off-label for this purpose; however its performance is typically inadequate, particularly for the detection of early stage disease and discrimination between benign versus malignant status. We recently described a multi-marker panel (MMP) and associated risk index for the differentiation of benign from malignant ovarian disease. In this study we applied a net reclassification approach to assess the use of MMP index to rescue those cases where low CA125 incorrectly excludes cancer diagnoses, or where benign disease is incorrectly assessed as "high risk" due to elevated CA125. Reclassification of such patients is of significant value to assist in the timely and accurate referral for patients where CA125 titer is uninformative.

Abstract
INTRODUCTION Multi-cancer early detection (MCED) blood tests look for cancer signals in cell-free deoxyribonucleic acid. These tests have the potential to detect cancers at an earlier (asymptomatic) stage, improving cancer outcomes. Any screening method needs careful consideration of the psychological harms prior to implementation. The aim of this research is to explore the psychological impact of having a cancer signal detected following an MCED blood test. METHODS AND ANALYSIS The project is embedded in the NHS-Galleri trial (ISRCTN91431511; NCT05611632), a large clinical trial in eight Cancer Alliances in England. In the trial, over 140 000 members of the general population aged 50-77 have been randomised 1:1 to either the intervention (blood tested with MCED test) or control (blood stored) arm. The proposed project focuses on participants in the intervention arm, who have a cancer signal detected. All participants who have a cancer signal detected (expected to be around 700 assuming a 1% test positive rate) will be sent a questionnaire at three timepoints: soon after receiving their result, 6 months and approximately 12 months later. The primary outcome is anxiety, assessed using the short-form 6-item Spielberger State Trait Anxiety Inventory. We will also assess the psychological consequences of screening (using the Psychological Consequences of Screening Questionnaire), reassurance/concern about the test result, understanding of results and help/health-seeking behaviour. A subsample of 40 participants (20 with a cancer diagnosis and 20 for whom no cancer was found) will be invited to take part in a one-to-one semistructured interview. ETHICS AND DISSEMINATION Ethical approval for this work has been granted by the Wales Research Ethics Committee as part of the NHS-Galleri trial (Ref 21/WA/0141). Consent to be sent questionnaires is collected as part of the main trial. A separate consent form will be required for interview. Results will be disseminated via peer-reviewed publication and conference presentations.

Abstract
Ovarian cancer most commonly presents at an advanced stage where survival is approximately 30% compared with >80% if diagnosed and treated before disease spreads. Diagnostic capabilities have progressed from surgical staging via laparotomy to image-guided biopsies and immunohistochemistry staining, along with advances in technology and medicine. Despite improvements in diagnostic capabilities, population-level screening for ovarian cancer is not recommended. Extracellular vesicles (EVs) are 40–150 nm structures formed when the cellular lipid bilayer invaginates. These structures function in cell signaling, immune responses, cancer progression, and establishing the tumor microenvironment. EVs are found in nearly every bodily fluid, including serum, plasma, ascites, urine, and effusion fluid, and contain molecular cargo from their cell of origin. This cargo can be analyzed to yield information about a possible malignancy. In this review we describe how the cargo of EVs has been studied as biomarkers in ovarian cancer. We bring together studies analyzing evidence for various cargos as ovarian cancer biomarkers. Then, we describe the role of EVs in modulation of the tumor microenvironment. This review also summarizes the therapeutic and translational potential of EVs for their optimal utilization as non-invasive biomarkers for novel treatments against cancer.

Abstract
OBJECTIVE Literature shows that emotional status can influence participation in screening/surveillance programs, and that screening/surveillance programs may alter the psychological well-being of subjects examined. This study aims to assess if participating in a surveillance program for pancreatic cancer early detection is associated with abnormal levels of psychological distress in high-risk individuals (HRIs), compared to the general population. METHODS Fifty-four HRIs participating in a magnetic resonance cholangiopancreatography (MRCP)-based surveillance program completed several psychological assessment questionnaires, investigating global functioning, self-efficacy, perceived stress, coping abilities, and social support. The questionnaires were administered by a clinical psychologist after the MRCP but before the subjects were informed about the results of the scans. The HRIs were subjects with strong familiarity of pancreatic cancer and/or carriers of known genetic mutations related to cancer susceptibility. The psychological assessment was made at the time of the first examination. RESULTS The population was characterized by an overall good psychological status. Scoring of our sample was comparable to the general population norms. The HRIs showed decent global functioning, high self-efficacy levels, low perceived stress in the last month prior to examination, efficient emotion-focused coping strategies, and an adequate social support system. The younger subjects' subpopulation only revealed higher levels of stress. CONCLUSIONS From a psychological point of view, an MRCP-based pancreatic cancer annual surveillance seemed not to influence the HRIs' psychological well-being, unless in young people. Further studies are needed to better establish if there are any changes in distress levels over time and how emotional status influences participation in surveillance programs.

Abstract
SummaryMainly diagnosed at advanced stage, ovarian cancer still remains the most lethal gynecological malignancy. Regarding screening and early detection, ovarian cancer poses particular challenges. To date, no screening test has been proven capable of leading to a mortality benefit. In this short review, we summarize and discuss the underlying literature on screening for ovarian cancer, focusing on average-risk, asymptomatic women as well as women at high risk. We also discuss the continuous advances and limits in liquid biopsies for early detection and screening of ovarian cancer.

Common mental disorders in Taiwanese consumers of commercial low-dose computed tomography lung cancer screening: Comparison with a nationally representative sample.

Abstract
BACKGROUND/PURPOSE We examined the prevalence of probable common mental disorders (CMDs) in commercial low-dose computed tomography (LDCT) lung cancer screening consumers relative to the general population and to determine the correlates of probable CMDs among screening participants. METHODS Commercial LDCT lung cancer screening consumers (N = 1323) were compared with a nationally representative sample from the Taiwan Social Change Survey (TSCS) (N = 2034). Respondents scoring ≥3 on the Chinese Health Questionnaire were classified as having a probable CMD. Logistic regression was used to investigate differences between the two groups and correlates of probable CMDs among LDCT lung cancer screening participants. RESULTS The prevalence of probable CMDs was higher among LDCT lung cancer screening participants (25.47%) than among TSCS adults (21.56%). Compared with the TSCS sample, the screening participants had a higher probability of CMDs (OR = 1.40, 95% CI = 1.13-1.73), higher education levels (OR = 7.95, 95% CI = 6.00-10.53), and a history of drinking (OR = 11.85, 95% CI = 9.45-14.85) or betel-quid use (OR = 5.43, 95% CI = 3.98-7.42) but were less likely to smoke (OR = 0.52, 95% CI = 0.40-0.68). Among the screening participants, being female (OR = 1.37, 95% CI = 1.02-1.84) and a current smoker (OR = 1.74, 1.19-2.54) and living near ≥2 smoking family members (OR = 2.30, 95% CI 1.57-3.38) were associated with an increased likelihood of having CMDs. CONCLUSION Commercial LDCT lung cancer screening users may have a positive association with probable CMDs compared to the general population. Screening programs should consider including criteria and providing psychoeducation to improve the physical and mental outcomes of participants. CLINICAL TRIAL REGISTRATION Purely observational studies (those in which the assignment of the medical intervention is not at the discretion of the investigator) do not require registration.

Abstract
Background Ovarian carcinoma is a poor prognosis cancer mainly due to its late diagnosis. Its incidence is relatively low but mortality is high. The symptomatology is only slightly specific, which complicates diagnostic management. It would therefore be interesting to be able to establish a diagnosis as early as possible in order to improve the prognosis of patients suffering from ovarian cancer. Materials and methods Currently, the combination of an ultrasound examination with a cancer antigen (CA)-125 assay is the most effective diagnostic technique, but not already admitted as a screening method. Therefore, we realized an exhaustive analysis of the most important studies in the last 15 years, in order to find new approaches in ovarian cancer screening. Results The age for initiating screening and its frequency are issues that are not fully resolved. The false positives and morbidity that result from screening are currently notable limitations. Conclusions The latest data do not support effective screening in the general population.

Abstract
OBJECTIVE Studies of cancer screening have found that false positive screening events (FPSE) can affect worry about cancer risk and screening program use, we sought to further explore this. METHOD In a study of 1,100 women at high risk for ovarian cancer who participated in a previously published randomized controlled trial (RCT), we sought to explore whether worry might also influence the use of risk-reducing surgical procedures by women. Participants included 234 women with BRCA1/2 mutations and 866 women with high-risk pedigrees. We followed the women for up to 6 years. RESULTS Worry predicted risk reducing prophylactic bilateral salpingo-oophorectomy (pBSO) for both mutation carriers (HR = 1.74; p = .02), and women with high-risk pedigree (HR = 3.41; p < .001). FPSE also predicted subsequent pBSO among women with a high-risk pedigree (HR 2.31; p < .01). While screening may reduce worry among those who never receive a positive result, FPSE increase worry at least temporarily. Worry about ovarian cancer risk predicted use of preventative pBSO among high-risk women including those with BRCA1/2 mutations enrolled in an ovarian cancer-screening program. FPSE also predicted risk-reducing ovarian surgery among high-risk women without a known mutation at the time of screening program enrollment. CONCLUSIONS Physicians who offer screening should know that false positive results may increase use of pBSO, how this should effect clinical practice is unclear.

Abstract
Background Pancreatic cancer screening is recommended to individuals at risk (IAR) of familial pancreatic cancer (FPC) families, but little is known about the acceptance of such screening programs. Thus, the acceptance and psychological aspects of a controlled FPC screening program was evaluated. Methods IAR of FPC families underwent comprehensive counseling by a geneticist and pancreatologist prior to the proposed screening. Participating IAR, IAR who discontinued screening and IAR who never participated in the screening program were invited to complete questionnaires to assess the motivation for participating in surveillance, cancer worries, structural distress and experiences with participation. Questionnaires were completed anonymously to receive most accurate answers. Results Of 286 IAR to whom pancreatic ductal adenocarcinoma (PDAC) screening was recommended, 139 (48.6%) IAR regularly participated (group 1), 49 (17.1%) IAR (group 2) discontinued screening after median 1 (1–10) screening visits and 98 (34.2%) IAR (group 3) never underwent screening. The overall response rate of questionnaires was 67% (189/286) with rates of 100% (139 of 139 IAR), 49% (29 of 49 IAR) and 23.4% (23 of 98 IAR) for groups 1, 2 and 3, respectively. At least 93% of IAR felt adequately informed about the screening program after initial counseling. However, only 38.8% received knowledge of or the recommendation for PDAC screening by physicians. The reported cancer-related distress and the fear of investigations were highest in group 1, but acceptably low in all three groups. The main reasons to discontinue or not to participate in screening were the time efforts and travel costs (groups 2 and 3 48,7%). Conclusion Less than 50% of IAR regularly participate in a proposed PDAC screening program, although the associated psychological burden is quite low. Physicians should be educated about high risk PDAC groups and screening recommendations. Time and travel efforts must be reduced to encourage more IAR to participate in a recommended screening.

Biomarker profiling for breast cancer detection: translational research to determine acceptance of a novel breast cancer screening technique. Health Syst (Basingstoke) 2018; 8:44-51.

Abstract
The current study seeks to determine how the psychosocial predictors of the health belief model are related to willingness to adopt biomarker screening practices among women above and below current screening age recommendations, as biomarker profiling can potentially detect cancer much earlier than current breast cancer detection methods. Patients (N = 205) at an Obstetrician/Gynaecology office in a mid-sized Midwest city. Participants completed a survey in the waiting room before their doctor appointment. Results revealed that benefits (p < .001), barriers (p = .02), cancer worry severity (p = .01), and self-efficacy (p = .002) were significant predictors of willingness to adopt biomarker profiling, and susceptibility was marginally related (p = .09). The direct effects are qualified by two interactions between psychosocial predictors of the health belief model and participants' age. The model predicted willingness to adopt biomarker screening well (R 2 = 28%), and may be used successfully as a framework to assess the diffusion of biomarker screening acceptability.

Abstract
Background In the absence of routine ovarian cancer screening, promoting help-seeking in response to ovarian symptoms is a potential route to early diagnosis. The factors influencing women’s anticipated time to presentation with potential ovarian cancer symptoms were examined. Methods Cross-sectional questionnaires were completed by a sample of women at increased familial risk (n = 283) and population risk (n = 1043) for ovarian cancer. Measures included demographic characteristics, symptom knowledge, anticipated time to symptom presentation, and health beliefs (perceived susceptibility, worry, perceived threat, confidence in symptom detection, benefits and barriers to presentation). Structural equation modelling was used to identify determinants of anticipated time to symptomatic presentation in both groups. Results Associations between health beliefs and anticipated symptom presentation differed according to risk group. In increased risk women, high perceived susceptibility (r = .35***), ovarian cancer worry (r = .98**), perceived threat (r = −.18**), confidence (r = .16**) and perceiving more benefits than barriers to presentation (r = −.34**), were statistically significant in determining earlier anticipated presentation. The pattern was the same for population risk women, except ovarian cancer worry (r = .36) and perceived threat (r = −.03) were not statistically significant determinants. Conclusions Associations between underlying health beliefs and anticipated presentation differed according to risk group. Women at population risk had higher symptom knowledge and anticipated presenting in shorter time frames than the increased risk sample. The cancer worry component of perceived threat was a unique predictor in the increased risk group. In increased risk women, the worry component of perceived threat may be more influential than susceptibility aspects in influencing early presentation behaviour, highlighting the need for ovarian symptom awareness interventions with tailored content to minimise cancer-related worry in this population.

Abstract
Cancer screening can facilitate early detection that improves survival, but also can identify an abnormal finding that is not malignant and deemed benign. While such false positive (FP) results can impact a variety of psychological outcomes, little is known about demographic, clinical, dispositional, and social-environmental characteristics associated with psychological outcomes after a FP result. Women participating in an ovarian cancer (OC) screening program and experiencing a FP screening test result (n = 375) completed assessments at baseline and 4-months. Results indicated greater social constraint and less education were linked to greater OC-specific distress at both assessments. Short-term predictors included less optimism and no previous abnormal test, while longer-term predictors were fewer previous screens and the interaction between OC family history and monitoring coping style. Younger age, less education, less optimism, greater social constraint, and family history of OC were associated with greater perceptions of OC risk. Brief interventions prior to screening may minimize the negative impact of a false positive result and not interfere with compliant participation in screening programs.

Abstract
OBJECTIVE The aim of the study was to assess whether adherence to annual clinical skin monitoring is dependent on patient sociodemographic characteristics or personality traits. DESIGN The study was a questionnaire survey. SETTING AND PARTICIPANTS Data were collected between February and April 2013 in a sample of 1000 patients at high risk of melanoma who participated in a pilot-targeted screening programme in western France. OUTCOME MEASURES Sociodemographic data, overall anxiety level (State-Trait Anxiety Inventory questionnaire), locus of control (Multidimensional Health Locus of Control scale) and levels of anxiety specifically associated with screening and melanoma were collected. Actual participation in the skin monitoring examination was reported by 78 general practitioner investigators. STATISTICAL ANALYSIS Statistical analysis was performed using R statistical software. Factors associated with non-adherence were identified by multivariate analysis. RESULTS Our analysis included 687 responses (526 adherent patients and 161 non-adherent patients). Non-adherence was higher in younger patients and in men (OR=0.63 (0.41-0.99)). Viewing health status as dependent on external persons (OR=0.90, 95% CI 0.83 to 0.97) or determined by chance (OR=0.89, 95% CI 0.80 to 0.98) and overall anxiety (OR=0.98, 95% CI 0.97 to 0.99) were also factors associated with non-adherence. In contrast, there was no link between anxiety specifically associated with the screening performed or melanoma and patient adherence to monitoring. Adherence was higher in married patients (OR=1.68 95% CI 1.08 to 2.60). CONCLUSIONS The results of this study suggest that sociodemographic and psychological characteristics should be considered when including patients at elevated risk of melanoma in a targeted screening programme.

Abstract
While participation in cancer screening can facilitate early detection and improved prognosis, all screening tests yield some proportion of abnormal test results which are later determined benign. These false positive (FP) results can negatively impact affective, cognitive, and behavioral outcomes. Women participating in an ovarian cancer (OC) screening program receiving an abnormal screening test result (n = 375) were matched with women receiving normal results (n = 375). Both groups completed a baseline and 1- and 4-month follow-up assessments. FP test results were clearly associated with increased cancer-specific distress and increased perceptions of OC risk with more limited evidence for increased perceived positive consequences of screening and increased intentions to participate in future OC screening. FP OC screening test results negatively impact both affective and cognitive outcomes which may serve to reduce motivation to participate in future routine screening. The development and testing of brief, timely interventions to minimize this negative impact is warranted.

Abstract
Evaluation of costs and benefits associated with cancer screening should include consideration of any psychological and behavioral impact associated with screening participation. Research examining the psychological and behavioral impact of screening asymptomatic women for ovarian cancer (OC) was considered. Research has focused upon potential negative psychological (e.g., distress) and behavioral (e.g., reduced future screening participation) impact of false positive (FP) OC test results. Results suggest FP OC screening results are associated with greater short-term OC-specific distress. While distress dissipates over time it may remain elevated relative to pre-screening levels for several weeks or months even after clinical follow-up has ruled out malignancy. The likelihood of participation in future OC screening may also be reduced. Research focused upon identification of any beneficial impact of participation in OC screening associated with receipt of “normal” results was also considered. This research suggests that a “normal” screening test result can have psychological benefits, including increased positive affect and beliefs in the efficacy of screening. It is concluded that any psychological or behavioral harms attributable to OC screening are generally very modest in severity and duration and might be counterbalanced by psychological benefits accruing to women who participate in routine OC screening and receive normal test results.

Abstract
OBJECTIVE Many studies have examined the relationship between worry and cancer screening. Due to methodological inconsistencies, results of these studies have varied and few conclusions can be made when generalizing across studies. The purpose of the current study was to better understand the worry-cancer screening relationship using a prospective research design. METHOD 180 women enrolled in an annual ovarian cancer (OC) screening clinic completed surveys at three time points-pre-screening, day of screening, and post-screening-using three measures of cancer-specific worry. RESULTS OC worry was highest in the weeks prior to screening and mere presentation at a screening clinic was associated with a significant worry decline. Observed elevations in worry following abnormal screening were not universal and varied by the instrument used to measure worry. CONCLUSIONS In contrast to our hypotheses, it appears that mere presentation at a cancer screening clinic may be a worry-reducing event. Receipt of abnormal results was not necessarily associated with increased worry.

Abstract
BACKGROUND Women at increased risk who decide not to have, or to delay, risk-reducing salpingo-oophorectomy have to rely on early diagnosis through symptom awareness and presenting to primary care as soon as possible in the absence of screening. However, little is known about the acceptability to women of this strategy. We aimed to gain an in-depth understanding of women's perceptions and previous experiences of ovarian cancer symptom management, and the influences on ovarian cancer awareness and anticipated symptom presentation. METHOD Qualitative interviews were conducted with eight women at increased risk of ovarian cancer who had previously taken part in ovarian cancer screening and analysed using interpretative phenomenological analysis (IPA). RESULTS Familial experience of ovarian cancer and perceived personal risk shaped women's perceptions and behavioural responses to disease threat. Ovarian cancer information was perceived to be a double-edged sword, regarded as either useful for increasing knowledge and confidence in discussing symptom concerns with health professionals or to be avoided due to fears about cancer. CONCLUSION Women may be cautious about searching for information independently and in the absence of routine ovarian screening. PRACTICE IMPLICATIONS Thought needs to be given to how best to create and disseminate credible ovarian cancer symptom information materials.

Abstract
Women with a documented deleterious mutation in BRCA1 or BRCA2 are at substantially elevated risk for ovarian cancer. To understand what percentage of women with high-risk family histories know their risk is elevated we surveyed 1,885 women with a high- or moderate-risk family history and no personal history of breast or ovarian cancer, and asked about their perceived risk of breast and ovarian cancer. Among high-risk women, fewer than 20% reported use of genetic counseling, and knowledge of elevated risk of ovarian cancer was low. Prior genetic counseling was associated with greater perceived risk for ovarian cancer. Results suggest that most high-risk women (>75%) do not know their risk for ovarian cancer. Identification of potentially high-risk women for referral to genetic counseling may improve informed ovarian cancer risk management.

Background While ovarian cancer is recognised as having identifiable early symptoms, understanding of the key determinants of symptom awareness and early presentation is limited. A population-based survey of ovarian cancer awareness and anticipated delayed presentation with symptoms was conducted as part of the International Cancer Benchmarking Partnership (ICBP). Methods Women aged over 50 years were recruited using random probability sampling (n = 1043). Computer-assisted telephone interviews were used to administer measures including ovarian cancer symptom recognition, anticipated time to presentation with ovarian symptoms, health beliefs (perceived risk, perceived benefits/barriers to early presentation, confidence in symptom detection, ovarian cancer worry), and demographic variables. Logistic regression analysis was used to identify the contribution of independent variables to anticipated presentation (categorised as < 3 weeks or ≥ 3 weeks). Results The most well-recognised symptoms of ovarian cancer were post-menopausal bleeding (87.4%), and persistent pelvic (79.0%) and abdominal (85.0%) pain. Symptoms associated with eating difficulties and changes in bladder/bowel habits were recognised by less than half the sample. Lower symptom awareness was significantly associated with older age (p ≤ 0.001), being single (p ≤ 0.001), lower education (p ≤ 0.01), and lack of personal experience of ovarian cancer (p ≤ 0.01). The odds of anticipating a delay in time to presentation of ≥ 3 weeks were significantly increased in women educated to degree level (OR = 2.64, 95% CI 1.61 – 4.33, p ≤ 0.001), women who reported more practical barriers (OR = 1.60, 95% CI 1.34 – 1.91, p ≤ 0.001) and more emotional barriers (OR = 1.21, 95% CI 1.06 – 1.40, p ≤ 0.01), and those less confident in symptom detection (OR = 0.56, 95% CI 0.42 – 0.73, p ≤ 0.001), but not in those who reported lower symptom awareness (OR = 0.99, 95% CI 0.91 – 1.07, p = 0.74). Conclusions Many symptoms of ovarian cancer are not well-recognised by women in the general population. Evidence-based interventions are needed not only to improve public awareness but also to overcome the barriers to recognising and acting on ovarian symptoms, if delays in presentation are to be minimised.

Abstract
OBJECTIVE We performed a systematic review and meta-analysis to quantify risks and benefits of screening asymptomatic women for ovarian cancer. METHODS We searched MEDLINE, EMBASE, CINAHL, and Cochrane CENTRAL, without language restrictions, from January 1, 1979 to February 5, 2012. Eligible studies randomly assigned asymptomatic women to screening or usual care. Two reviewers independently screened studies for eligibility, extracted data using a standardized, piloted extraction form, and assessed bias and strength of inference for each outcome using the GRADE framework. Chance-corrected agreement was calculated at each step, and disagreements were resolved through consensus. RESULTS Ten randomized trials proved eligible. Screening did not reduce all-cause mortality (relative risk (RR)=1.0, 95% confidence interval (CI) 0.96-1.06), ovarian cancer specific mortality (RR=1.08, 95% CI 0.84-1.38), or risk of diagnosis at an advanced stage (RR of diagnosis at FIGO stages III-IV=0.86, 95% CI 0.68-1.11). Transvaginal ultrasound resulted in a mean of 38 surgeries per ovarian cancer detected (95% CI 15.7-178.1) while screening with CA-125 led to 4 surgeries per ovarian cancer detected (95% CI 2.7-4.5). Surgery was associated with severe complications in 6% of women (95% CI 1%-11%). Quality of life was not affected by screening; however, women with false-positive results had increased cancer-specific distress compared to those with normal results (odds ratio (OR)=2.22, 95% CI 1.23-3.99). CONCLUSIONS Screening asymptomatic women for ovarian cancer does not reduce mortality or diagnosis at an advanced stage and is associated with unnecessary surgery.

Abstract
AIM AND OBJECTIVES To measure health-related quality of life, anxiety and depression ahead of mammography screening and to assess any differences in health-related quality of life compared to reference population. BACKGROUND The study of health-related quality of life among attendees prior to mammography screening has received little attention, and increased knowledge is needed to better understand the overall health benefits of participation. DESIGN A two-group cross-sectional comparative study was performed. METHODS The samples comprised 4,249 attendees to mammography screening and a comparison group of 943 women. We used the SF-36 Health Survey to assess health-related quality of life. Linear regression was used to study any differences between the groups with adjustment for age, level of education, occupation, having children and smoking status. Other normative data were also used. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale. RESULTS Attendees scored statistically significant higher on the SF-36 than the comparison group but were in line with normative data. Attendees had anxiety mean 4·1 and depression mean 2·6. CONCLUSIONS The majority of the attendees have a high health-related quality of life, low anxiety and depression ahead of screening. Anxiety and depression were less than shown in normative data from Norway. Despite a high health-related quality of life, low anxiety and depression among the majority, healthcare workers should pay special attention to the few women who are anxious and depressed, and have a lower health-related quality of life. Omitted from mammography screening may be women who are unemployed, have lower socioeconomic status, are anxious and are depressed. Further research should be performed with non-attendees and subgroups to improve the screening programme. RELEVANCE TO CLINICAL PRACTICE It is important to identify which patients have the greatest need for support and caring in an organised mammography screening and who may be overlooked.

Abstract
BACKGROUND There is a widely held expectation that screening for disease has adverse emotional impacts. The aim of the current review is to estimate the short (< 4 weeks) and longer term (> 4 weeks) emotional impact of such screening. METHODS Studies selected for inclusion were (a) randomised controlled trials in which (b) participants in one arm underwent screening and received test results, and those in a control arm did not, and (c) emotional outcomes were assessed in both arms. MEDLINE via PubMed (1950 to present), EMBASE (1980 to present), PsycINFO (1985 to present) using OVID SP, and CINAHL (1982 to present) via EBSCO were searched, using strategies developed with keywords and medical subject headings. Data were extracted on emotional outcomes, type of screening test and test results. RESULTS Of the 12 studies that met the inclusion criteria, six involved screening for cancer, two for diabetes, and one each for abdominal aortic aneurysms, peptic ulcer, coronary heart disease and osteoporosis. Five studies reported data on anxiety, five [corrected] on depression, two on general distress and eight on quality of life assessed between one week and 13 years after screening (median = 1.3 years).Meta-analyses revealed no significant impact of screening on longer term anxiety (pooled SMD 0.01, 95% CI -0.10, 0.11), depression (pooled SMD -0.04, 95% CI -.12, 0.20), or quality of life subscales (mental and self-assessed health pooled SMDs, respectively: 0.03; -0.01, (95% CI -.02, 0.04; 0.00, 95% CI -.04, 0.03). CONCLUSION Screening does not appear to have adverse emotional impacts in the longer term (> 4 weeks). Too few studies assessed outcomes before four weeks to comment on the shorter term emotional impact of screening.

Abstract
Past research has suggested that dispositional cancer worry may be a key predictor of health behavior. The current study examined seven measures of dispositional cancer worry to see if they were significantly related (convergent validity), significantly different from similar but distinct traits (divergent validity), and capable of predicting cancer-relevant outcomes (predictive validity). Four hundred and eighty nine undergraduate students completed a survey measuring dispositional worry, dispositional cancer worry, and perceived cancer risk. Factor analysis identified four underlying dimensions that explained 67.3% of the variance in dispositional cancer worry: severity (42.8%), frequency (12.3%), psychological reactance (6.9%), and worry impact (5.3%). Four existing measures of dispositional cancer worry were found to represent each of these dimensions. In general, dispositional cancer worry measures were highly correlated with one another and only moderately correlated with measures of dispositional worry, supporting strong convergent and divergent validity. Hierarchical regression analyses revealed that dispositional cancer worry measures predicted significant variance in cancer-relevant outcomes above and beyond dispositional worry. The results of the current study support the notion that dispositional cancer worry and dispositional worry are distinct constructs. Furthermore, two dimensions of dispositional cancer worry (severity and frequency) seemed to have the strongest convergent, divergent, and predictive validity.

Abstract
All cancer screening tests produce a proportion of abnormal results requiring follow up. Consequently, the cancer-screening setting is a natural laboratory for examining psychological and behavioural response to a threatening health-related event. This study tested hypotheses derived from the social cognitive processing and cognitive-social health information processing models in trying to understand response to an abnormal ovarian cancer (OC) screening test result. Women (n = 278) receiving an abnormal screening test result a mean of 7 weeks earlier were assessed prior to a repeat screening test intended to clarify their previous abnormal result. Measures of disposition (optimism, informational coping style), social environment (social support and constraint), emotional processing, distress, and benefit finding were obtained. Regression analyses indicated greater distress was associated with greater social constraint and emotional processing and a monitoring coping style in women with a family history of OC. Distress was unrelated to social support. Greater benefit finding was associated with both greater social constraint and support and greater distress. The primacy of social constraint in accounting for both benefit finding and distress was noteworthy and warrants further research on the role of social constraint in adaptation to stressful events.

Abstract
Individuals at increased risk for pancreatic cancer who undergo screening can experience psychological and emotional distress. The objective of this study is to determine whether individuals participating in a pancreatic cancer screening program experience disruptions in risk perception, cancer-related anxiety or emotional distress. A pretestposttest design was used to examine perceived risk and psychological functioning of individuals participating in a pancreatic cancer screening protocol. The screening protocol includes genetic counselling, transcutaneous abdominal ultrasound, magnetic resonance imaging, and blood collection and eligible participants included individuals with a family history of pancreatic cancer or BRCA2 mutation carriers. At baseline, participants (n = 198) showed low to moderate levels of risk perception, pancreatic cancer-related anxiety, and general distress. Participants with familial pancreatic cancer (FPC) (n = 131) endorsed higher risk perception of pancreatic cancer than the BRCA2 carriers (n = 67) (perceived lifetime risk 42 vs. 15%), but did not differ on cancer worry or general distress prior to the first study appointment. From baseline to 3 months follow-up, no significant time or time by group interactions emerged on risk perception or general distress, but cancer worry decreased over time for the FPC group regardless of the number of affected relatives. Our findings indicate that participation in a pancreatic cancer screening program does not lead to a significant increase in risk perception, cancer worry, or general distress and that participants with high baseline levels of risk perception and distress may benefit from a more comprehensive risk assessment and psychological support.

Abstract
PURPOSE To measure circulating antigens, sandwich ELISA assays require two complementary affinity reagents. Mouse monoclonal antibodies (mAb) and polyclonal antibodies (pAb) are commonly used, but because their production is lengthy and costly, recombinant antibodies are emerging as an attractive alternative. EXPERIMENTAL DESIGN We developed a new class of recombinant antibodies called biobodies (Bb) and compared them to mAb for use in serodiagnosis. Bbs were secreted biotinylated in vivo by diploid yeast and used as affinity reagents after Ni purification. Bead-based assays for HE4 and mesothelin were developed using Bbs in combination with pAbs (Bb/pAb assays). To assess precision, reproducibility studies were done using four runs of 16 replicates at six analyte levels for each marker. Pearson correlations and receiver-operator characteristic analyses were done in 214 patient serum samples to directly compare the Bb/pAb assays to mAb assays. Diagnostic performance of the Bb/pAb assay was further assessed in an expanded set of 336 ovarian cancer cases and controls. RESULTS On average across analyte levels, Bb/pAb assays yielded within-run and between-run coefficients of variations of 11.7 and 23.8, respectively, for HE4 and 14.0 and 14.5, respectively, for mesothelin. In the subset (n = 214), Pearson correlations of 0.95 for HE4 and 0.92 for mesothelin were observed between mAb and Bb/pAb assays. The area under the curves for the mAb and Bb/pAb assays were not significantly different for HE4 (0.88 and 0.84, respectively; P = 0.20) or mesothelin (0.74 and 0.72, respectively; P = 0.38). CONCLUSION Yeast-secreted Bbs can be used reliably in cost-effective yet highly sensitive bead-based assays for use in large validation studies.
