Piloting gender-oriented colorectal cancer screening with a faecal immunochemical test: population-based registry study from Finland.

OBJECTIVE: To assess the feasibility and evaluate the performance of a relaunched colorectal cancer (CRC) screening programme with different cut-offs for men and women. DESIGN: Population-based registry study. SETTING: Nine municipalities in Finland which started CRC screening with faecal immunochemical test (FIT) in April 2019 with cut-off levels 70 µg Hg/g faeces for men and 25 µg Hg/g faeces for women. PARTICIPANTS: Men (n=13 059) and women (n=14 669) aged 60-66 years invited to screening during the first programme year. OUTCOME MEASURES: Participation rates, positivity rates, detection rates of CRC and advanced adenoma (AA), and positive predictive values (PPV) of FIT for CRC and AA. RESULTS: Altogether 21 993 invitees returned stool samples. The participation rate of women (83.4%; 95% CI 82.8 to 84.0) was significantly higher than that of men (74.7%; 95% CI 73.9 to 75.4). The positivity rates were 2.4% (2.2 to 2.7) and 2.8% (2.5 to 3.1), respectively. In total, 37 CRCs and 116 AAs were detected. The detection rates of CRC and AA per 1000 participants were 1.8 (1.1 to 2.9) and 7.2 (5.6 to 9.1) for men and 1.6 (0.9 to 2.4) and 3.8 (2.8 to 5.0) for women. The PPVs per 100 positive tests were 6.6 (4.0 to 10.3) and 25.7 (20.6 to 31.4) for men and 6.4 (3.9 to 9.8) and 15.5 (11.6 to 20.2) for women. CONCLUSIONS: The chosen FIT strategy narrowed the gap in the diagnostic performance between men and women especially in the detection of CRC. The participation rates were excellent. The levels of positivity and detection rates were moderate and need further action. The results indicate that gender-specific protocols can be introduced to organised CRC screening. It is yet to be seen whether they are more effective than a uniform screening protocol.

Embedded survey study harms colorectal cancer screening attendance: Experiences from Finland 2010 to 2015.

Objective We previously found that administering a pre-screening lifestyle questionnaire lowered the subsequent attendance proportion in the first-ever colorectal cancer screening. We sought to determine whether the effect continued in subsequent screening rounds. Methods The eligible survey cohort ( n = 10,375) received a follow-up questionnaire in 2012, and in 2013, they were invited for colorectal cancer screening for the second time. For the third screening round, in 2015, no questionnaires were sent in the previous year. Screening attendance in 2013 and in 2015 was examined in relation to survey mailings. Results The colorectal cancer screening attendance rate in 2013 was 58.4% in the survey population, and 63.9% in those not surveyed ( P < 0.001). In 2015, the screening attendance rate was 61.7% among those who had been sent the questionnaires in 2010 and in 2012, and 66.2% in those not surveyed ( P < 0.001). The reduction in screening attendance was greater at the second (2013) round than at the first (2011). Conclusion The effect of the initial survey seemed to continue even when no questionnaires were being sent. Attendance among those who had been sent questionnaires earlier did not reach the level of the group that was never surveyed.

Lifestyle in population-based colorectal cancer screening over 2-year follow-up.

Background: Colorectal cancer (CRC) screening may cause changes in health-related lifestyle. In 2010, Finnish Mass Screening Registry began a study on psychosocial effects of CRC screening. This article examines whether there are differential developments in self-reported lifestyle at ages 59-61 years among CRC screening invitees and non-contacted controls. Methods: A population-based random sample of 10 648 Finnish adults born in 1951 and living in the municipalities voluntary involved in the CRC screening programme were sent a lifestyle questionnaire in 2010. In 2011, the cohort was randomised (1 : 1) for their first ever CRC screening at age 60 or for controls. The questionnaires were repeated in 2012 for all. From both survey rounds, 2508 pairs of completed questionnaires were available for analysis from the screening group and 2387 from the control group. The outcome was 2-year change in total lifestyle index of CRC risk factors (diet, physical activity, body mass index, alcohol consumption and smoking). Results: Total lifestyle index decreased throughout the follow-up in both the screening group [odds ratio (OR) = 0.80, 95% confidence interval (CI) 0.72-0.90] and in the control group (OR = 0.80, CI 0.71-0.90) indicating no difference in lifestyle changes between groups. There was also no significant difference by screening participation: the change in score was similar in those participating screening (OR 0.81, CI 0.72-0.92) and in those invited, but not participating (OR 0.75, CI 0.55-1.03). Conclusion: Present study found no unfavourable changes in total lifestyle in the studied age group due to CRC screening. Results are reassuring from the point of view of CRC screening evaluation.

Respondent selection in a repeated survey on lifestyle within the randomized colorectal cancer screening programme.

Screening for colorectal cancer (CRC) has been shown to decrease colorectal cancer mortality in randomized-controlled trials. However, screening may have an adverse impact on an individual's lifestyle. We describe here the design of a repeated survey study on lifestyle and assess response in the survey target population by randomization to CRC screening and demographic factors. The survey study population (n=10271) included Finnish men and women born in 1951 who were randomized for the CRC screening programme in 2011 and received a questionnaire on lifestyle in 2010 and 2012. We assessed responding by randomization to CRC screening, calendar time and demographic factors using the population-averaged Poisson model. Responding to survey was overall similar in 2010 and 2012. Those invited for CRC screening increased responding in time [incidence rate ratio (IRR) 1.06, confidence interval (CI) 1.03-1.09], whereas controls decreased their responding (IRR 0.97, CI 0.94-1.00). Women were more likely to respond than men (IRR 1.17, CI 1.12-1.23). Also, secondary (IRR 1.20, CI 1.13-1.27) and tertiary (IRR 1.31, CI 1.23-1.40) level education increased the response proportion compared with primary-level education. We could reliably assess the effect of CRC screening invitation and demographic factors on survey response. Although invitation to CRC screening increased responding, the self-selection was similar on both survey rounds. Self-selection should be taken into account when generalizing results from survey studies to their target population.

Patient experiences at diagnosis and psychological well-being in prostate cancer: A Finnish national survey.

PURPOSE: Most cases of prostate cancer are diagnosed at an early stage, and men live for many years after diagnosis. Thus, their well-being and quality of life are of great importance. This study investigated patient experiences and psychological well-being in a Finnish national sample of prostate cancer patients who received various types of treatment. METHOD: In a national sample (50%) of prostate cancer patients diagnosed in Finland in 2004, information was collected on the patients' experiences at diagnosis and choice of treatment (e.g. treatment selection, patient satisfaction with care and information, psychological reactions). In 2009, participants were asked about their experiences, and psychological well-being (psychological symptoms, satisfaction with life) was measured. In total, 1239 completed questionnaires (73%) were accepted for the study. Differences between treatments and predictors of psychological well-being were investigated using descriptive statistics and regression analysis. RESULTS: Half of the respondents were satisfied with the care and information they received about the cancer and side effects of treatment. Experiences and psychological well-being were most positive among patients who received brachytherapy and poorest among patients who received hormonal therapy. Patients who underwent prostatectomy or brachytherapy were most likely to have been involved in treatment selection. Negative experiences, such as learning of the diagnosis in an impersonal way and dissatisfaction with the information and care received, were predictive of poorer well-being. CONCLUSIONS: Unmet supportive care and informational needs were common. Experiences and well-being varied between treatments. Patients tended to prefer prostatectomy and brachytherapy. Unmet needs, which would probably be reduced by improvements in care, appear to have a long-lasting impact on patients' psychological well-being.

Effect of a pre-screening survey on attendance in colorectal cancer screening: a double-randomized study in Finland.

OBJECTIVES: To explore effects of a pre-screening life style survey on the subsequent attendance proportion in colorectal cancer screening. SETTING: Finnish colorectal cancer screening programme in 2011. DESIGN: Double randomized and controlled follow-up design. METHODS: The study population comprised of 31,951 individuals born in 1951. In 2010 to a random sample of every sixth (n = 5,312) person we sent a 7-paged life style questionnaire, and to another random sample of every sixth person (n = 5,336) a 10-paged life style and quality of life questionnaire. One year later, in 2011, 31,484 individuals of the original cohort were independently randomized (1:1) for colorectal cancer screening (n = 15,748) or control group (n = 15,736). Of those who were invited for screening, 5185 had received a questionnaire during the previous year. RESULTS: 5870 individuals (55.1 %) responded to the questionnaire in 2010. The overall attendance at screening in 2011 was 59.0 % in those born in 1951 (i.e. the 60-year-olds). In those who had been sent the survey the attendance in screening was 56.6% (57.3% for the short and 56.0% for the long questionnaire) and in those who had not received the questionnaire it was 60.2% (P < 0.001). CONCLUSIONS: We believe that the observed reduction in attendance in those who had been sent a questionnaire earlier is generally true. Thus, if any survey is enclosed in the screening invitation, this finding should be taken into account when planning the programme. Any extra effort requested may reduce the attendance proportion for screening, reducing the population level impact of screening.
