Psychological distress following fecal occult blood test in colorectal cancer screening--a population-based study

Psychological Impact of the Galleri test (sIG(n)al): protocol for a longitudinal evaluation of the psychological impact of receiving a cancer signal in the NHS-Galleri trial

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.

New Mental Health Diagnosis as a Prognostic Factor for Muscle-Invasive Bladder Cancer

BACKGROUND

To examine differences in survival outcomes for muscle-invasive bladder cancer patients stratified by new mental health diagnosis.

METHODS

Using the Surveillance, Epidemiology, and End Results (SEER)-Medicare data, we identified patients diagnosed with muscle-invasive bladder cancer between 2008 and 2014. Our primary outcome was cancer-specific and overall hazards of mortality. As a secondary outcome, we reported predictors of developing a new mental health diagnosis after bladder cancer diagnosis. We used Cox proportional hazards models to determine the impact of palliative care and mental health diagnoses on survival outcomes after adjusting for grade, stage, comorbidity index, and baseline demographics.

RESULTS

Of the 3794 patients who met inclusion criteria, 1193 (31%) were diagnosed with a mental health illness after their bladder cancer diagnosis during the 6 years in the study period. The most common diagnoses were depression (13%), alcohol and drug abuse (12%), and anxiety (11%). Patients with a post-bladder cancer mental health diagnosis had a 57% higher hazard of overall mortality (HR 1.57, P = .048) and an 80% higher hazard of bladder cancer-specific mortality (HR 1.81, P = .037) CONCLUSIONS: New mental health diagnoses are associated with worse survival in patients with muscle invasive bladder cancer. This suggests that a multimodal approach to bladder cancer treatment should include addressing the non-oncologic needs of the patient to optimize survival outcomes.

Methodological Quality of PROMs in Psychosocial Consequences of Colorectal Cancer Screening: A Systematic Review

Objective

This systematic review aimed to assess the adequacy of measurement properties in Patient-Reported Outcome Measures (PROMs) used to quantify psychosocial consequences of colorectal cancer screening among adults at average risk.

Methods

We searched four databases for eligible studies: MEDLINE, CINAHL, PsycINFO, and Embase. Our approach was inclusive and encompassed all empirical studies that quantified aspects of psychosocial consequences of colorectal cancer screening. We assessed the adequacy of PROM development and measurement properties for content validity using The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) risk of bias checklist.

Results

We included 33 studies that all together used 30 different outcome measures. Two PROMs (6.7%) were developed in a colorectal cancer screening context. COSMIN rating for PROM development was inadequate for 29 out of 30 PROMs (97%). PROMs lacked proper cognitive interviews and pilot studies and therefore had no proven content validity. According to the COSMIN checklist, 27 out of 30 PROMs (90%) had inadequate measurement properties for content validity.

Discussion

The majority of included PROMs had inadequate development and measurement properties. These findings shed light on the trustworthiness of the included studies' findings and call for reevaluation of existing evidence on the psychosocial consequences of colorectal cancer screening. To provide trustworthy evidence about the psychosocial consequences of colorectal cancer screening, editors could require that studies provide evidence of the methodological quality of the PROM. Alternatively, authors should transparently disclose their studies' methodological limitations in measuring psychosocial consequences of screening validly.

Evaluating the Impact of Acromegaly on Quality of Life

Acromegaly has a substantial negative impact on quality of life (QoL). This review aims to discuss the impact of acromegaly on QoL from the clinical perspective as well as from the patient perspective. Furthermore, it aims to evaluate the use of patient-reported outcome measures (PROMs) in acromegaly and how PROMs aid decision-making. The recommendations presented in this review are based on recent clinical evidence on the impact of acromegaly on QoL combined with the authors' own clinical experience treating patients with acromegaly. We recommend that a patient-centered approach should be considered in treatment decisions, integrating conventional biochemical outcomes, tumor control, comorbidities, treatment complications, and PROMs, including QoL measures. This more integrated approach seems effective in treating comorbidities and improving patient-reported outcomes and is critical, as many patients do not achieve biochemical or tumor control and comorbidities, impairment in QoL may not remit even when full biochemical control is achieved.

The role of genetic predisposition in cardiovascular risk after cancer diagnosis: a matched cohort study of the UK Biobank

BACKGROUND

Evidence is scarce regarding the potential modifying role of disease susceptibility on the association between a prior cancer diagnosis and cardiovascular disease (CVD).

METHODS

We conducted a matched cohort study of UK Biobank including 78,860 individuals with a cancer diagnosis between January 1997 and January 2020, and 394,300 birth year and sex individually matched unexposed individuals. We used Cox model to assess the subsequent relative risk of CVD, which was further stratified by individual genetic predisposition.

RESULTS

During nearly 23 years of follow-up, an elevated risk of CVD was constantly observed among cancer patients, compared to their matched unexposed individuals. Such excess risk was most pronounced (hazard ratio [HR] = 5.28, 95% confidence interval [CI] 4.90-5.69) within 3 months after a cancer diagnosis, which then decreased rapidly and stabilised for >6 months (HR = 1.22, 95% CI 1.19-1.24). For all the studied time periods, stratification analyses by both levels of polygenic risk score for CVD and by family history of CVD revealed higher estimates among individuals with lower genetic risk predisposition.

CONCLUSIONS

Our findings suggest that patients with a recent cancer diagnosis were at an increased risk of multiple types of CVD and the excess CVD risk was higher among individuals with lower genetic susceptibility to CVD, highlighting a general need for enhanced psychological assistance and clinical surveillance of CVD among newly diagnosed cancer patients.

The half-painted picture: Reviewing the mental health impacts of cancer screening

Cancer screening is recommended for select cancers worldwide. Cancer screening has become increasingly effective and accessible and often increases overall survival. However, the mental health effects of cancer screening, such as its impact on depression, anxiety, and post-traumatic stress disorder, are largely unknown. Conflicting available literature indicates the negative, neutral, and positive mental health effects of cancer screening across cancer types. There are a limited number of randomized controlled trials measuring the mental health effects of cancer screening. Overall, the more negative and life-threatening the screening results, the greater the mental health effects. Screening for cancer without a known precursor, for example, due to family history, can have positive impacts such as decreased worry and increased quality of life. However, receiving a cancer diagnosis often has negative mental effects that increase with the life-threatening potential of malignancy. In this study, we review the existing literature and provide recommendations for future research to determine if and when cancer screening is the best practice.

Short and long-term psychosocial consequences of participating in a colorectal cancer screening programme: a matched longitudinal study

OBJECTIVES

To investigate the psychosocial consequences of receiving a false-positive (no abnormalities) result or being diagnosed with polyps compared with receiving a negative result in a colorectal cancer (CRC) screening programme.

DESIGN AND SETTING

This was a longitudinal study nested in the roll-out of the Danish CRC screening programme that targets all individuals aged 50-74 years.

PARTICIPANTS

In the inclusion period (April-September 2017), all positive screenees (n=1854) were consecutively enrolled and matched 2:1:1 on sex, age (±2 years), municipality and screening date with negative screenees (n=933) and individuals not yet invited to screening (n=933).Questionnaires were sent by mail to all eligible participants in Region Zealand, Denmark, after the screening result, 2 months and 12 months after the final result.Positive screenees who did not receive the follow-up procedure were excluded.

MAIN OUTCOME MEASURES

The primary outcomes were psychosocial consequences. Outcomes were measured with the CRC screening-specific questionnaire Consequences of screening in CRC with 11 outcomes after the screening result and with 21 outcomes at the two later assessments.

RESULTS

After receiving the screening result, individuals with no abnormalities, low-risk and medium-risk and high-risk polyps scored significantly worse on 8 of 11 outcomes compared with the negative screenee group. At the 12-month follow-up, the differences were still significant in 8 of 21 outcomes (no abnormalities), 4 of 21 outcomes (low-risk polyps) and 10 of 21 outcomes (medium-risk and high-risk polyps). The negative screenee group and the group not yet invited to screening differed psychosocially on 5 of 11 outcomes after the screening result, but on none of the 21 outcomes at the 2 months and 12 months follow-up.

CONCLUSIONS

The study showed that there are both short-term and long-term psychosocial consequences associated with receiving a no abnormalities result or being diagnosed with polyps. The consequences were worst for individuals diagnosed with medium-risk and high-risk polyps.

Increased Risk of Suicide among Cancer Survivors Who Developed a Second Malignant Neoplasm

Background. Cancer diagnosis entails substantial psychological distress and is associated with dramatically increased risks of suicidal behaviors. However, little is known about the suicide risk among cancer survivors who developed a second malignant neoplasm (SMN). Methods. Using the Surveillance, Epidemiology, and End Results database, we conducted a population-based cohort study involving 7,824,709 patients with first malignant neoplasm (FMN). We measured the hazard ratios (HRs) of suicide death after receiving a SMN diagnosis using Cox proportional hazard models, as compared with patients with FMN. The comparison with the US population was achieved by calculating standardized mortality ratios (SMRs). Results. Totally 685,727 FMN patients received a diagnosis of SMN during follow-up, and we in total identified 10,930 and 937 suicide deaths among FMN and SMN patients, respectively. The HR of suicide deaths was 1.23 (95% confidence interval (CI), 1.14–1.31) after a SMN diagnosis, compared with FMN patients, after adjusting for sociodemographic factors, tumor characteristics, and cancer treatment. As compared with the general population, while both SMN and FMN patients suffered an increased risk of suicide deaths, the excess risk was higher among SMN patients than FMN patients (age-, sex-, and calendar-year-adjusted SMR 1.65 (95% CI 1.54–1.75) vs. 1.29 (95% CI 1.26–1.31); $P_{\text{difference}}<0.0001$ ). Notably, across different time periods, we observed the greatest risk elevation during the first 3 months after a cancer diagnosis. Conclusions. Compared with either patients with FMN or the general population, cancer survivors who received a SMN diagnosis were at increased risk of suicide death. The risk elevation was most prominent soon after the cancer diagnosis, highlighting the necessity of providing timely psychological support to cancer survivors with a SMN.

The psychological impact of esophageal cancer screening on anxiety and depression in China

OBJECTIVE

The psychological impact of screening is unclear and has been ignored. This study aimed to evaluate the psychological impact of esophageal cancer (EC) screening on anxiety and depression in China.

MATERIALS AND METHODS

A multicenter, population-based study in five high-risk regions of EC was conducted from 2019 to 2020. Residents were recruited and underwent endoscopic screening and then were diagnosed with normal, esophagitis, low-grade intraepithelial neoplasia (LGIN), high-grade intraepithelial neoplasia (HGIN) and EC. Subjects who did not participate in the screening were referred to as the control group. We surveyed their anxiety and depression levels at baseline and after endoscopy and informed them of different pathological results to evaluate the psychological impact of the screening process.

RESULTS

A total of 2,337 subjects completed all surveys in the screening process (normal: 355, esophagitis: 1,713, LGIN: 213, HGIN: 43 and EC: 13), with 63 controls. The levels of anxiety and depression of screeners were significantly higher than those of controls (P < 0.001). The fluctuation of anxiety and depression showed a "V" pattern in the screening process. The prevalence of anxiety symptoms at baseline, after endoscopy and after knowing the pathological results was 5.6, 0.3, and 3.2%, respectively (P < 0.001), and the corresponding prevalence of depression was 3.6, 0.2, and 2.1%, respectively (P < 0.001). With the aggravation of pathological results, the levels of anxiety and depression increased significantly (P < 0.001), especially in patients informed of HGIN (16.3 and 9.3%) and EC (23.1 and 30.8%).

CONCLUSION

Participation in endoscopic screening may bring short-term adverse psychological effects, especially at baseline and knowing the pathological results. More attention should be given to participants waiting for endoscopic screening. The method of informing the screening results of HGIN and EC should be improved. Further precise screening is needed to concentrate on high-risk groups to reduce the psychological impact of screening.

Psychiatric disorders and cardiovascular diseases during the diagnostic workup of potential breast cancer: a population-based cohort study in Skåne, Sweden

Background

An increasing number of women are evaluated for potential breast cancer and may experience mental distress during evaluation. We aim to assess the risks of psychiatric disorders and cardiovascular diseases during the diagnostic workup of potential breast cancer.

Methods

All women with a new diagnosis of unspecified lump in breast (N = 15,714), benign tumor or breast cancer in situ (N = 4435), or breast cancer (N = 8512) during 2005–2014 in Skåne, Sweden, were considered as exposed to a breast diagnostic workup. We used multivariable Poisson regression to compare rates of psychiatric disorders and cardiovascular diseases during the 6 weeks before the date of diagnosis of these women with the corresponding rates of women not undergoing such workup. The commonest waiting time for breast cancer patients was 6 weeks during the study period. A within-individual comparison was performed to control for potential unmeasured time-stationary confounders.

Results

Compared to the reference, we found a higher rate of psychiatric disorders during the 6 weeks before diagnosis of benign tumor or breast cancer in situ (incidence rate ratio [IRR], 1.3; 95% confidence interval [CI], 1.1 to 1.5) and breast cancer (IRR, 1.4; 95% CI, 1.2 to 1.6). A higher rate was also noted for cardiovascular diseases (IRR, 1.3; 95% CI, 1.1 to 1.6 for benign tumor or breast cancer in situ, and IRR, 1.9; 95% CI, 1.8 to 2.0 for breast cancer). The rate increases for breast cancer were greater comparing a diagnostic workup due to symptoms to a workup due to screening. Little rate increase of neither psychiatric disorders nor cardiovascular diseases was noted during the 6 weeks before the diagnosis of unspecified lump in breast. The within-individual comparison largely confirmed these findings.

Conclusions

Women with benign and malignant breast tumor had increased rates of psychiatric disorders and cardiovascular diseases during the waiting for a final diagnosis.

Short-term impact of breast cancer screening intervention on health-related quality of life in China: A multicentre cross-sectional survey

OBJECTIVE

The impact of participating in breast cancer screening programmes on health-related quality of life (HRQoL)is poorly understood.

METHODS

Based on a national breast cancer screening programme in China, a multicentre cross-sectional survey was conducted covering 12 provinces from September 2013 to December 2014. HRQoL of participants in the screening population and general population was evaluated by the three-levelEuroQol-five-Dimensions (EQ-5D-3L) instrument, and utility scores were generated through the Chinese value set. Univariate and multivariate regression analyses were performed to explore determinants of utility scores and anxiety/depression problems.

RESULTS

For screening group and general population (n = 4756, mean age = 51.6 year old), the corresponding utility scores were 0.937 (95% CI, 0.933-0.941) and 0.953 (0.949-0.957) (P < .001). Pain/discomfort and anxiety/depression were the most common reported in both groups (51.4% and 34.3%, P < .001). Utility scores at prescreening, in-screening, and postscreening interview timings were 0.928 (0.921-0.935), 0.958 (0.948-0.969), and 0.938 (0.933-0.943), respectively (P < .001); the corresponding proportions of anxiety/depression reporting were 25.9%, 16.3%, and 21.1%, respectively (P = .004). Interview timing, geographical region, and insurance status were associated with HRQoL and anxiety/depression in women at high-risk of breast cancer.

CONCLUSIONS

Utility scores of screening participants were significantly lower than that of general population in China, but the difference may be clinically insignificant. Further cohort studies using HRQoL measurements are needed.

A stitch in time saves nine: Perceptions about colorectal cancer screening after a non-cancer colonoscopy result. Qualitative study

OBJECTIVES

To explore perceptions of colorectal cancer (CRC) screening among participants who have experienced a 'false alarm' for CRC, and to explore perceptions about the relevance of screening for themselves or others.

METHODS

Semi-structured interviews with screening participants who had participated in the Danish CRC screening program and experienced a 'false alarm' for colorectal cancer. A thematic analysis was performed, based on an interpretive tradition of ethnography.

RESULTS

Perceptions about CRC screening after a non-cancer colonoscopy result were characterized by trust in the colonoscopy result showing no CRC, and satisfaction with the screening offer despite the risk for 'false alarm'. The patient-involving behavior of the healthcare professionals during the examination was for most participants a cornerstone for trusting the validity of the colonoscopy result showing no CRC. Strong notions about perceived obligation to participate in screening were common.

CONCLUSIONS

Prominent themes were trust in the result, satisfaction with the procedure, and moral obligations to participate both for themselves and for others.

PRACTICE IMPLICATIONS

Information to future invitees after a 'false alarm' experience could build on peoples' trust in the validity of a previous non-cancer result and should underscore the importance of subsequent screening even after a 'false alarm' for cancer.

Psychosocial consequences of receiving false-positive colorectal cancer screening results: a qualitative study

Objective: The objective of this study was to investigate the psychosocial consequences of receiving false-positive colorectal cancer (CRC) screening results, following a positive immunochemical faecal occult blood test. Design, setting, and subjects: We conducted a qualitative study with four semi-structured focus group interviews with 16 participants aged 50-74, all of whom had received a false-positive result in the national Danish CRC screening programme. We selected, recruited, and grouped participants to ensure maximum variation, and to enable a level of confidence to speak openly about experiences of screening. We subjected interview data, audio-recordings, and transcripts to a strategy of qualitative analysis called systematic text condensation. Results: We identified four main themes which described the psychosocial consequences of false-positive CRC screening results: anxiety; discomfort; changed self-perception and behaviour; and considerations on participation in screening. Each of these themes covered a wide range of experiences which were relevant to the informants and broadly shared by them in many aspects. Conclusions: Receiving false-positive results from CRC screening can lead to negative psychosocial consequences such as changes in self-perception and anxiety: some participants may experience subsequent relief, others not. These negative psychosocial consequences might persist over time. Implications: Negative psychosocial consequences from false-positive CRC screening results may result in a greater use of general practitioner services by healthy people who need reassurance or further tests. More research using condition-specific measures is required to further understand the degree and potential persistence of psychosocial consequences of false-positive results from CRC screening. Key Points Participants who receive false-positive colorectal cancer (CRC) screening results may experience negative psychosocial consequences e.g. anxiety and subsequent relief. Participants who receive false-positive CRC screening results may experience discomfort during the screening process. Participants who receive false-positive CRC screening results may experience longer term changes of self-perception. Participants who receive false-positive CRC screening results may experience ambivalence about the offered diagnostic down-stream procedures including colonoscopy.

Persuasion, Adaptation, and Double Identity: Qualitative Study on the Psychological Impact of a Screen-Detected Colorectal Cancer Diagnosis

The NHS Bowel Cancer Screening Programme (BCSP) is aimed at reducing colorectal cancer (CRC) mortality through early detection within a healthy population. This study explores how 5 people (three females) experience and make sense of their screen-detected diagnosis and the psychological implications of this diagnostic pathway. A biographical narrative interview method was used, and transcripts were analysed using a thematic analysis with a phenomenological lens. Themes specifically relating to posttreatment experience and reflections are reported here: Do it: being living proof, Resisting the threat of recurrence, Rationalising bodily change, and Continuing life-"carrying on normally." Participants described their gratefulness to the BCSP, motivating a strong desire to persuade others to be screened. Furthermore, participants professed a duality of experience categorised by the normalisation of life after diagnosis and treatment and an identification of strength post cancer, as well as a difficulty adjusting to the new changes in life and a contrasting identity of frailty. Understanding both the long- and short-term impacts of a CRC diagnosis through screening is instrumental to the optimisation of support for patients. The results perhaps highlight a particular target for psychological distress reduction, which could reduce the direct and indirect cost of cancer to the patient.

Psychosocial consequences of skin cancer screening

Screening for melanoma may save lives, but may also cause patient distress. One key reason that preventative visual skin examinations for skin cancer are not currently recommended is the inadequate available evidence to assess potential harm to psychosocial wellbeing. We investigated potential psychological harms and benefits of skin examinations by conducting telephone surveys in 2015 of 187 screened participants; all were ≥35 years old. Participants had their skin examined by practitioners who had completed INFORMED, a validated web-based training for detection of skin cancers, particularly melanoma. Participants underwent the Spielberger State-Trait Anxiety Inventory (STAI), Psychological Consequences of Screening (PCQ), Hospital Anxiety and Depression (HAD) scale, and the 12-Item Short Form Health Survey (SF-12). Analyses were conducted in 2017. Of the entire study sample, 40% were thoroughly screened as determined by patient-reported level of undress and skin areas examined. Participants who were thoroughly screened: did not differ on negative psychosocial measures; scored higher on measures of positive psychosocial wellbeing (PCQ); and were more motivated to conduct monthly self-examinations and seek annual clinician skin examinations, compared to other participants (p < 0.05). Importantly, thoroughly screened patients were more likely to report skin prevention practices (skin self-examinations to identify a concerning lesion, practitioner provided skin exam), recommend skin examinations to peers, and feel satisfied with their skin cancer education than less thoroughly screened individuals (p < 0.01). Our results suggest that visual screening for skin cancer does not worsen patient psychosocial wellbeing and may be associated with improved skin cancer-related practices and attitudes.

Primary care visit use after positive fecal immunochemical test for colorectal cancer screening

BACKGROUND

For some patients, positive cancer screening test results can be a stressful experience that can affect future screening compliance and increase the use of health care services unrelated to medically indicated follow-up.

METHODS

Among 483,216 individuals aged 50 to 75 years who completed a fecal immunochemical test to screen for colorectal cancer at a large integrated health care setting between 2007 and 2011, the authors evaluated whether a positive test was associated with a net change in outpatient primary care visit use within the year after screening. Multivariable regression models were used to evaluate the relationship between test result group and net changes in primary care visits after fecal immunochemical testing.

RESULTS

In the year after the fecal immunochemical test, use increased by 0.60 clinic visits for patients with true-positive results. The absolute change in visits was largest (3.00) among individuals with positive test results who were diagnosed with colorectal cancer, but significant small increases also were found for patients treated with polypectomy and who had no neoplasia (0.36) and those with a normal examination and no polypectomy performed (0.17). Groups of patients who demonstrated an increase in net visit use compared with the true-negative group included patients with true-positive results (odds ratio [OR], 1.60; 95% confidence interval [95% CI], 1.54-1.66), and positive groups with a colorectal cancer diagnosis (OR, 7.19; 95% CI, 6.12-8.44), polypectomy/no neoplasia (OR, 1.37; 95% CI, 1.27-1.48), and normal examination/no polypectomy (OR, 1.24; 95% CI, 1.18-1.30).

CONCLUSIONS

Given the large size of outreach programs, these small changes can cumulatively generate thousands of excess visits and have a substantial impact on total health care use. Therefore, these changes should be included in colorectal cancer screening cost models and their causes investigated further. Cancer 2017;123:3744-3753. © 2017 American Cancer Society.

A systematic review of the psychological impact of false-positive colorectal cancer screening: What is the role of the general practitioner?

Screening for colorectal cancer (CRC) has both advantages (e.g. reduction in morbidity and mortality) and disadvantages (e.g. false positives and distress). A systematic review was therefore performed to improve our understanding of how false-positive CRC screening results affect patients psychologically (and to make recommendations for primary care). The PubMed, Embase, PsychINFO, CINAHL and Cochrane databases were searched in October 2014 and supplemented in December 2016 to identify studies on the psychological impact of false-positive CRC screening. Original studies were eligible when they assessed psychological impact in a screening setting, provided they also included false-positive CRC screening results. Two authors independently assessed 2,367 available manuscripts and included seven. Heterogeneity in their outcome measures meant that data could not be pooled. Two studies showed that a false-positive CRC screening result caused some moderate psychological distress shortly before and after colonoscopy. The remaining five studies illustrated that the psychological distress of patients with true-positive and false-positive CRC screening results was comparable. We conclude that a false-positive CRC screening result may cause some moderate psychological distress, especially just before or after colonoscopy. We recommend that general practitioners mention this when discussing CRC screening with patients and monitor those with a false-positive outcome for psychological distress.

Psychological effects of colorectal cancer screening: Participants vs individuals not invited

AIM

To investigate the possible long-term psychological harm of participating in colorectal cancer (CRC) screening in Norway.

METHODS

In a prospective, randomized trial, 14294 participants (aged 50-74 years) were invited to either flexible sigmoidoscopy (FS) screening, or a faecal immunochemical test (FIT) (1:1). In total, 4422 screening participants (32%) completed the questionnaire, which consisted of the Hospital Anxiety and Depression Scale and the SF-12, a generic health-related quality of life (HRQOL) measurement, when invited to screening and one year after the invitation. A control group of 7650 individuals was invited to complete the questionnaire only, at baseline and one year after, and 1911 (25%) completed the questionnaires.

RESULTS

Receiving a positive or negative screening result and participating in the two different screening modalities did not cause clinically relevant mean changes in anxiety, depression or HRQOL after one year. FS screening, but not FIT, was associated with an increased probability of being an anxiety case (score ≥ 8) at the one-year follow-up (5.6% of FS participants transitioned from being not anxious to anxious, while 3.0% experienced the reverse). This increase was moderately significantly different from the changes in the control group (in which the corresponding numbers were 4.8% and 4.5%, respectively), P = 0.06.

CONCLUSION

Most individuals do not experience psychological effects of CRC screening participation after one year, while FS participation is associated with increased anxiety for a smaller group.

Do no harm: no psychological harm from colorectal cancer screening

Background:

Participation in cancer screening programmes might cause worries in the population outweighting the benefits of reduced mortality. The present study aimed to investigate possible psychological harm of participation in a colorectal cancer (CRC) screening pilot in Norway.

Methods:

In a prospective, randomised trial participants (aged 50–74 years) were invited to either flexible sigmoidoscopy (FS) screening, faecal immunochemical test (FIT), or no screening (the control group; 1 : 1: 1). Three thousand two hundred and thirteen screening participants (42% of screened individuals) completed the Hospital Anxiety and Depression Scale questionnaire as well as the SF-12—a health-related quality of life (HRQOL) questionnaire when invited to screening and when receiving the screening result. A control group was invited to complete the questionnaires only. Two thousand six hundred and eighteen control participants (35% of invited individuals) completed the questionnaire.

Results:

A positive screening result did not increase participants' level of anxiety or depression, or decrease participants' level of HRQOL. Participants who received a negative result reported decreased anxiety and improvement on some HRQOL dimensions. However, no change was considered to be of clinical relevance.

Conclusion:

The current study showed no clinically relevant psychological harm of receiving a positive CRC screening result or of participating in FS or FIT screening, in a Norwegian population.

The psychological impact of participating in colorectal cancer screening by faecal immuno-chemical testing--the Australian experience

BACKGROUND

Occult blood-based colorectal cancer (CRC) screening may result in adverse psychological outcomes for participants. The aims of this study were to measure the psychological consequences of participating in screening at key points along the screening and diagnostic pathway, and examine variation over time within or between test outcome groups.

METHODS

A total of 301 people (positives=165, negatives=136) aged 50-76 years were surveyed via validated psychological questionnaires after result notification, post colonoscopy (positives only) and 1 year following result notification.

RESULTS

Negatives scored significantly higher in quality of life domains and lower state anxiety, anger and depression in comparison to positives both after result notification and at 1 year follow-up. Positives had significantly decreased state anxiety and depression at 1 year and improvement in HLoC power and reduced screening decision doubtfulness post colonoscopy. Positives experienced heightened CRC risk perception both after result notification and at 1 year follow-up in comparison to negatives, but reported less difficulty participating in ongoing screening.

CONCLUSIONS

In positives, increased anxiety and doubtfulness about the decision to screen declined over time. Lower CRC risk perception in negatives indicates the need for education to promote CRC screening participation.

Ethical issues in colorectal cancer screening

In many countries, colorectal cancer screening is currently an established population screening program due to the evidence on its reduction of colorectal cancer mortality. There is general consensus that colorectal cancer screening meets the screening criteria as proposed by Wilson and Jungner. However, as for all population screening programs, colorectal cancer screening also has disadvantages and thereby entails ethical issues. There are the general issues concerning the introduction of screening programs (e.g. medicalization, overdiagnosis and overtreatment, information provision to screenees), evaluation of cancer screening programs (e.g. lead time and length bias), chosen screening method (e.g. false-positive and false-negative test results, reduction of all-cause mortality, choice between different screening methods). The different colorectal cancer screening methods and the ethical issues concerning colorectal cancer screening will be discussed in this review.

Psychological distress after a positive fecal occult blood test result among members of an integrated healthcare delivery system

BACKGROUND

Colorectal cancer screening (CRCS) reduces morbidity and mortality; however, the positive benefits might be partially offset by long-term distress following positive screening results. We examined relationships among colorectal cancer-specific worry and situational anxiety after positive fecal occult blood tests [FOBT (+)] compared with receipt of negative results.

METHODS

Of note, 2,260 eligible members of Group Health, an integrated healthcare delivery system, completed baseline surveys and received FOBT screening kits, with 1,467 members returning the kits. We matched FOBT (+) patients (n = 55) 1:2 on age and sex with FOBT (-) respondents (n = 110). Both groups completed follow-up surveys at 7 to 14 days and 4 months after screening. We assessed situational anxiety (State-Trait Anxiety Inventory, STAI), colorectal cancer worry frequency, and mood disturbance.

RESULTS

Mean age was 59 years, and majority were women (62%) and White (89%). After adjusting for age, sex, and baseline worry, at 7 to 14 days after screening, the FOBT (+) group was 3.82 [95% confidence interval (CI), 1.09-13.43] times more likely to report colorectal cancer-related mood disturbances and significantly higher mean STAI scores than the FOBT (-) group (mean = 38.8 vs. 30.9; P = 0.007). At 4-month posttest, mood disturbances and situational anxiety seemed to drop to baseline levels for FOBT (+). No colon cancer worry frequency was observed.

CONCLUSIONS

FOBT (+) results are associated with short-term situational anxiety and colorectal cancer-specific mood disturbances.

IMPACT

Distress from FOBT (+) results declined to near-baseline levels by 4 months. Additional studies are needed to clarify the relationship between long-term distress and follow-up colonoscopy.

False negative fecal occult blood test may be associated with increased mortality from colorectal cancer

BACKGROUND

Fecal Occult Blood Test (FOBT) is an accepted screening test for colorectal cancer (CRC). It has been shown to decrease mortality by up to 30%. The outcome of screening failures has not been adequately studied.

AIMS

The purpose of this study was to assess the outcome of patients who were diagnosed with CRC after a false negative FOBT.

METHODS

We identified all consecutive CRCs from pathology reports between 2005 and 2010. Patients were divided according to their FOBT result. Those who became positive were compared to patients who remained negative.

RESULTS

Altogether 401 CRCs were identified. Of those, 202 never performed a FOBT. At least one negative FOBT was performed by 133 individuals (67%). Of these, 76 remained negative (false negatives, FN) and 57 became positive (positive conversion, PC, controls). The prevalence of metastatic disease was threefold higher among the FNs as compared to the PC group (16 [22.2%] vs. 4 [7.5%], P=0.022). All-cause mortality was also significantly higher among FNs versus PCs (24 [31.6%] vs. 5 [8.8%], P=0.001); in Cox regression analysis of survival (covariates: FNs vs. PC, gender, age, medications and co-morbidities) FNs had increased mortality compared to the PC (HR 2.929, P=0.033, CI 95% 1.092-7.858). No statistically significant difference was found regarding all primary end points when comparing the FN and the "No test" group.

CONCLUSION

These data disclose a particular risk of FOBT as a screening test. A subgroup of patients with "false" negative tests may have increased morbidity and mortality. Efforts should be made to recognize and characterize this high-risk group.

FIT false-positives in colorectal cancer screening experience psychological distress up to 6 weeks after colonoscopy

PURPOSE

Screening programs for colorectal cancer aim at reducing cancer mortality. We assessed psychological effects of being invited to an immunochemical fecal test (FIT)-based screening program.

METHODS

Asymptomatic persons aged 50-74 years were invited to a Dutch screening pilot. The Psychological Consequences Questionnaire (PCQ) was used to measure the psychological effects of screening. Screen positives had two additional measurements: before undergoing the colonoscopy and 4 weeks after receiving the colonoscopy findings.

RESULTS

A number of 3,828 invitees (46 % male, mean age 60 years) completed the first PCQ. FIT positives had a higher mean total PCQ score (8.32, SD 8.84; score range 0-36) than those who declined participation (3.72, SD 6.30); participants still waiting for their FIT result had a mean score of 2.74 (SD 5.11), and those with a negative FIT result had the lowest score (2.06, SD 4.43) (p < 0.001). In the 373 FIT positives who underwent colonoscopy, 195 completed the pre-colonoscopy questionnaire and 253, the post-colonoscopy questionnaire. Mean total, physical, and social PCQ scores had decreased significantly between the first questionnaire and the pre-colonoscopy one, but scores on the emotional subscale did not. In false-positives, mean total, physical, and emotional PCQ scores decreased significantly, while in true-positives, a significant decrease in mean emotional PCQ score was observed.

CONCLUSION

Psychological consequences for invitees to a Dutch FIT-based colorectal cancer screening pilot differ, depending on timing and FIT result. FIT positives are more distressed than FIT negatives. FIT positives still experience psychological distress 6 weeks after a normal colonoscopy.

Quality of life in participants of a CRC screening program

Background:

Little is known about the effect of participating in a colorectal cancer (CRC) screening programme on quality of life (QOL), neither for participants with a negative nor for those with a positive test result. These findings, however, are important to evaluate the impact of CRC screening.

Methods:

Participants from CRC screening trials were sent a questionnaire, which included validated measures on generic health-related QOL, generic anxiety and screen-specific anxiety. Both faecal immunochemical test (FIT) and flexible sigmoidoscopy (FS) participants, either with negative or positive test results, were addressed.

Results:

The response rate was 73% (1289 out of 1772) for FIT and 78% (536 out of 689) for FS participants, with mean ages varying from 63–66 years. Positive FIT participants had worse physical (PCS-12, 47.1 vs 48.3, P=0.02), but equal mental QOL scores (MCS-12, 51.1 vs 51.6, P=0.26). Positive and negative FS participants had similar QOL scores. Both FIT and FS participants with a positive test result reported more screen-specific anxiety than negative FIT and FS participants. Positive and negative FS participants had similar generic anxiety scores.

Conclusion:

Our findings indicate that the burden of participating in CRC screening may be limited. Conducting a prospective study to confirm these results is recommended.

Screening for colorectal cancer: possible improvements by risk assessment evaluation?

Emerging results indicate that screening improves survival of patients with colorectal cancer. Therefore, screening programs are already implemented or are being considered for implementation in Asia, Europe and North America. At present, a great variety of screening methods are available including colono- and sigmoidoscopy, CT- and MR-colonography, capsule endoscopy, DNA and occult blood in feces, and so on. The pros and cons of the various tests, including economic issues, are debated. Although a plethora of evaluated and validated tests even with high specificities and reasonable sensitivities are available, an international consensus on screening procedures is still not established. The rather limited compliance in present screening procedures is a significant drawback. Furthermore, some of the procedures are costly and, therefore, selection methods for these procedures are needed. Current research into improvements of screening for colorectal cancer includes blood-based biological markers, such as proteins, DNA and RNA in combination with various demographically and clinically parameters into a "risk assessment evaluation" (RAE) test. It is assumed that such a test may lead to higher acceptance among the screening populations, and thereby improve the compliances. Furthermore, the involvement of the media, including social media, may add even more individuals to the screening programs. Implementation of validated RAE and progressively improved screening methods may reform the cost/benefit of screening procedures for colorectal cancer. Therefore, results of present research, validating RAE tests, are awaited with interest.
