Introduction Mortality from colorectal cancer has been shown to decrease by repeated screening using faecal occult blood (FOB) testing in randomized screening trials. This report presents coverage and performance of organized screening among the general population in Finland. Methods In 2004-2007, people aged 60-69 years were randomized into biennial screening and control arms. The screening test was a guaiac-based FOB test (Hemoccult®) with dietary restriction and three test cards for six consecutive samples. Test positives were referred for full colonoscopy. The programme was launched in 2004 and subsequently it expanded over regions and age-cohorts. Results In 2007, the programme covered one-third of the target population and 74,592 people had been invited for screening, of them 26,866 for the second round. Uptakes for the first and second rounds, respectively, were 62% and 68% in men and 77% and 80% in women. The proportion of test positives increased from 2.4% to 2.9% from the first to the second round and the positive predictive value for cancers decreased from 7.5% to 4.3%. Conclusions By 2007, organized colorectal cancer screening covered one-third of the target population in Finland. Implementation of screening measured with response rate was successful and met the criteria for a public health programme, but performance in terms of positive predictive value needs monitoring.

Aim: The aim of the present study was to examine the impact of obesity and physical activity on the health and wellbeing of patients with breast cancer shortly after the adjuvant treatments., Patients and Methods: A total of 537 women aged 35 to 68 years with newly-diagnosed breast cancer were enrolled into the exercise intervention study. The physical activity, physical performance (2-km walking test), cardiovascular risk factors, quality of life (EORTC-QoL-C30), co-morbidities and body-mass index (BMI) were measured after the adjuvant treatments., Results: Overall, 191 (39%) patients were overweight (BMI=25-30) and 85 (17%) obese (BMI ≥ 30). Physical activity and performance (p<0.001 and p<0.001), QoL (p<0.001) and high density lipoprotein (HDL)-cholesterol decreased (p<0.001) whereas age (p=0.009), co-morbidities (p<0.001), hypertension (p=0.011), metabolic syndrome (p<0.001), low density lipoprotein (LDL)-cholesterol (p=0.0043), triglycerides (p<0.001), glucose (p<0.001) and insulin (p<0.001) increased linearly with BMI. Higher waist circumference (p=0.0011), triglyceride (p=0.020), insulin (p=0.0098), rate of metabolic syndrome (p=0.028), and lower HDL-cholesterol (p=0.012) and QoL (p<0.001) were associated with low physical activity. Physical activity and BMI were the most important determinants of physical performance (p<0.001 and p<0.001, respectively)., Conclusion: Obesity and a sedentary lifestyle are related to poor physical performance, increased risk of cardiovascular diseases and impaired QoL, leading to a vicious circle, which impairs patients' physical health and QoL.

Aim: The study aimed at determining whether physical exercise training improves the quality of life (QoL) and physical fitness of breast cancer survivors., Patients and Methods: A total of 573 breast cancer survivors were randomized into an exercise or a control group, 12-months after adjuvant treatments. EORTC QLQ-C30 and BR-23 questionnaires were used for evaluation of QoL, FACIT-F for fatigue and the Finnish modified version of Beck's 13-item depression scale (RBDI) for depression. Physical fitness was assessed by a 2-km walking test, and a figure-8 running test and physical activity (PA) by metabolic equivalent (MET) hours per week (MET-h/wk)., Results: Figure-8 running time improved significantly among the patients of the intervention group compared with the controls (p<0.001). No significant between-group differences were observed in 2-km walking time, in PA, EORTC-QLQ-C30, BR-23, FACIT-F or BDI. However, there was a linear relationship between increased PA and improved QoL (p=0.006), irrespective of the intervention., Conclusion: Increase in physical activity was associated with improved QoL, but no effect of the exercise intervention was observed.
