Background There remains disagreement on the long-term effect of mammographic screening in women aged 40–49 years. Objectives The long-term follow-up of a randomised controlled trial that offered annual mammography to women aged 40–49 years. The estimation of the effect of these mammograms on breast cancer and other-cause mortality, and the effect on incidence, with implications for overdiagnosis. Design An individually randomised controlled trial comparing offering annual mammography with offering usual care in those aged 40–48 years, and thus evaluating the effect of annual screening entirely taking place before the age of 50 years. There was follow-up for an average of 23 years for breast cancer incidence, breast cancer death and death from other causes. We analysed the mortality and incidence data by Poisson regression and estimated overdiagnosis formally using Markov process models. Setting Twenty-three screening units in England, Wales and Scotland within the NHS Breast Screening Programme. Participants Women aged 39–41 years were recruited between 1990 and 1997. After exclusions, a total of 53,883 women were randomised to undergo screening (the intervention group) and 106,953 women were randomised to have usual care (the control group). Interventions The intervention group was invited to an annual breast screen with film mammography, two view at first screen and single view thereafter, up to and including the calendar year of their 48th birthday. The control group received no intervention. Both groups were invited to the National Programme from the age of 50 years, when screening is offered to all women in the UK. Main outcome measures The main outcome measures were mortality from breast cancers diagnosed during the intervention phase of the trial (i.e. before the first National Programme screen at 50 years), mortality from all breast cancers diagnosed after randomisation, all-cause mortality, mortality from causes other than breast cancer, and the incidence of breast cancer. Results There was a statistically significant 25% reduction in mortality from breast cancers diagnosed during the intervention phase at 10 years’ follow-up (relative rate 0.75, 95% confidence interval 0.58 to 0.97; p = 0.03). No reduction was observed thereafter (relative rate 0.98, 95% confidence interval 0.79 to 1.22). Overall, there was a statistically non-significant 12% reduction (relative rate 0.88, 95% confidence interval 0.74 to 1.03; p = 0.1). The absolute benefit remained approximately constant over time, at one death prevented per 1000 women screened. There was no effect of intervention on other-cause mortality (relative rate 1.02, 95% confidence interval 0.97 to 1.07; p = 0.4). The intervention group had a higher incidence of breast cancer than the control group during the intervention phase of the trial, but incidence equalised immediately on the first National Programme screen at the age of 50–52 years. Limitations There was 31% average non-compliance with screening and three centres had to cease screening for resource and capacity reasons. Conclusions Annual mammographic screening at the age of 40–49 years resulted in a relative reduction in mortality, which was attenuated after 10 years. It is likely that digital mammography with two views at all screens, as practised now, could improve this further. There was no evidence of overdiagnosis in addition to that which already results from the National Programme carried out at later ages. Future work There is a need for research on the effects of modern mammographic protocols and additional imaging in this age group. Trial registration Current Controlled Trials ISRCTN24647151.

PURPOSE Observational studies of dietary fat intake and breast cancer have reported inconsistent findings. This topic was addressed in additional analyses of the Women’s Health Initiative (WHI) Dietary Modification (DM) clinical trial that evaluated a low-fat dietary pattern influence on breast cancer incidence. METHODS In the WHI DM trial, 48,835 postmenopausal women, ages 50-79 years, with no prior breast cancer, and a dietary fat intake of ≥ 32% of energy were randomly assigned at 40 US centers to a usual diet comparison group (60%) or dietary intervention group (40%). The goals were to reduce fat intake to 20% of energy and increase vegetable, fruit, and grain intake. Breast cancers were confirmed after central medical record review and serial National Death Index linkages to enhance mortality findings. RESULTS During 8.5 years of dietary intervention, breast cancer incidence and deaths as a result of breast cancer were nonsignificantly lower in the intervention group, while deaths after breast cancer were statistically significantly lower both during intervention and through a 16.1-year (median) follow-up. Now, after a long-term, cumulative 19.6-year (median) follow-up, the significant reduction in deaths after breast cancer persists (359 [0.12%] v 652 [0.14%] deaths; hazard ratio [HR], 0.85; 95% CI, 0.74 to 0.96; P = .01), and a statistically significant reduction in deaths as a result of breast cancer (breast cancer followed by death attributed to the breast cancer) emerged (132 [0.037%, annualized risk] v 251 [0.047%] deaths, respectively; HR, 0.79; 95% CI, 0.64 to 0.97; P = .02). CONCLUSION Adoption of a low-fat dietary pattern associated with increased vegetable, fruit, and grain intake, demonstrably achievable by many, may reduce the risk of death as a result of breast cancer in postmenopausal women.

BackgroundAlthough depression is a common problem among non-professional caregivers, only one trial has evaluated the efficacy of indicated prevention targeting this population and the long-term efficacy is unknown. The aim of this study was to evaluate the long-term efficacy of a brief intervention for the indicated prevention of depression in a sample of female caregivers.MethodA randomized controlled trial was conducted involving 173 participants (mean age 53.9 years) who were allocated to the intervention (n = 89) or the usual-care control group (n = 84). Blinded interviewers conducted assessments at 1, 3, 6 and 12 months of follow-up. The main outcome measure was the incidence of major depression and the secondary outcomes were compliance with treatment, depressive symptoms, emotional distress and caregiver burden.ResultsAt the 12-month follow-up, a lower incidence of depression as evaluated using the Structured Clinical Interview for Axis I Disorders of the DSM-IV was found in the intervention group compared with the control group (10.1%v.25.0%). The relative risk was 0.40 and statistically significant [χ2 = 6.68, degrees of freedom = 1,p = 0.010, 95% confidence interval (CI) 0.20–0.81], and the number needed to treat was 7 (95% CI 4–27). There was a significant delay in the onset of depression in the intervention group (p = 0.008). The good complier caregivers had a lower incidence of depression. The intervention effect on depressive symptoms, emotional distress and caregiver burden were maintained for 12 months.ConclusionsThis is the first study to demonstrate that a brief problem-solving intervention can prevent the onset of depression among non-professional caregivers over the longer term.

Abstract Purpose Peripheral neuropathy is a complication of taxane that in severe cases can limit the optimal treatment. The aim of this study was to evaluate the efficacy of memantine in prevention of docetaxel induced peripheral neuropathy in patients with breast cancer. Methods In this randomized clinical trial, 40 women between the ages of 18 and 64 years with non-metastatic breast cancer (stages I to III) were included (registry number: IRCT20160310026998N9 and registry date: 26 March 2019). All patients were treated with the AC-T regimen (with docetaxel). Patients in intervention group received memantine at a dose of 20 mg for 8 weeks at the beginning of the first cycle of docetaxel. Patients in control group did not take any medication for neuropathy prevention. To assess the neuropathy, DN4 and CTCAE questionnaires were used at baseline, one months, three months and six months after the intervention. Results The DN4 questionnaire score was remarkably less in memantine group in follow up one (p-value: 0.033) and three (p < 00.1). The CTCAE follow up score did not change during study. The Neuropathy duration and Neuropathy onset, were shown significant difference between the intervention and control groups, p = 0.050 and p = 0.001, respectively. From 40 patients, 8 (40%) in memantine group and 2 (10%) in control group, did not experience any kind of neuropathy. Conclusion Data showed that prophylactic administration of memantine 20 mg/day has been effective in prevention of severity and incidence of docetaxel induced neuropathy in patients with breast cancer.

Abstract Background Cardiometabolic diseases (CMD) are the major cause of death worldwide and are associated with a lower quality of life and high healthcare costs. To prevent a further rise in CMD and related healthcare costs, early detection and adequate management of individuals at risk could be an effective preventive strategy. The objective of this study was to determine long-term cost-effectiveness of stepwise CMD risk assessment followed by individualized treatment if indicated compared to care as usual. A computer-based simulation model was used to project long-term health benefits and cost-effectiveness, assuming the prevention program was implemented in Dutch primary care. Methods A randomized controlled trial in a primary care setting in which 1934 participants aged 45–70 years without recorded CMD or CMD risk factors participated. The intervention group was invited for stepwise CMD risk assessment through a risk score (step 1), additional risk assessment at the practice in case of increased risk (step 2) and individualized follow-up treatment if indicated (step 3). The control group was not invited for risk assessment, but completed a health questionnaire. Results of the effectiveness analysis on systolic blood pressure (− 2.26 mmHg; 95% CI − 4.01: − 0.51) and total cholesterol (− 0.15 mmol/l; 95% CI − 0.23: − 0.07) were used in this analysis. Outcome measures were the costs and benefits after 1-year follow-up and long-term (60 years) cost-effectiveness of stepwise CMD risk assessment compared to no assessment. A computer-based simulation model was used that included data on disability weights associated with age and disease outcomes related to CMD. Analyses were performed taking a healthcare perspective. Results After 1 year, the average costs in the intervention group were 260 Euro higher than in the control group and differences were mainly driven by healthcare costs. No meaningful change was found in EQ 5D-based quality of life between the intervention and control groups after 1-year follow-up (− 0.0154; 95% CI − 0.029: 0.004). After 60 years, cumulative costs of the intervention were 41.4 million Euro and 135 quality-adjusted life years (QALY) were gained. Despite improvements in blood pressure and cholesterol, the intervention was not cost-effective (ICER of 306,000 Euro/QALY after 60 years). Scenario analyses did not allow for a change in conclusions with regard to cost-effectiveness of the intervention. Conclusions Implementation of this primary care-based CMD prevention program is not cost-effective in the long term. Implementation of this program in primary care cannot be recommended.

This study aimed to explore the application value of the intelligent medical communication system based on the Apriori algorithm and cloud follow-up platform in out-of-hospital continuous nursing of breast cancer patients. In this study, the Apriori algorithm is optimized by Amazon Web Services (AWS) and graphics processing unit (GPU) to improve its data mining speed. At the same time, a cloud follow-up platform-based intelligent mobile medical communication system is established, which includes the log-in, my workstation, patient records, follow-up center, satisfaction management, propaganda and education center, SMS platform, and appointment management module. The subjects are divided into the control group (routine telephone follow-up, 163) and the intervention group (continuous nursing intervention, 216) according to different nursing methods. The cloud follow-up platform-based intelligent medical communication system is used to analyze patients’ compliance, quality of life before and after nursing, function limitation of affected limb, and nursing satisfaction under different nursing methods. The running time of Apriori algorithm is proportional to the data amount and inversely proportional to the number of nodes in the cluster. Compared with the control group, there are statistical differences in the proportion of complete compliance data, the proportion of poor compliance data, and the proportion of total compliance in the intervention group ( P < 0.05 ). After the intervention, the scores of the quality of life in the two groups are statistically different from those before treatment ( P < 0.05 ), and the scores of the quality of life in the intervention group were higher than those in the control group ( P < 0.05 ). The proportion of patients with limited and severely limited functional activity of the affected limb in the intervention group is significantly lower than that in the control group ( P < 0.05 ). The satisfaction rate of postoperative nursing in the intervention group is significantly higher than that in the control group ( P < 0.001 ), and the proportion of basically satisfied and dissatisfied patients in the control group was higher than that in the intervention group ( P < 0.05 ).

PURPOSE The prognostic role of the site of the primary breast cancer has not been clarified. This study aimed to gather more information about this issue from a large series of patients with long-term follow-up data. PATIENTS AND METHODS Data from 2,396 patients treated for early breast cancer with a conservative approach were reviewed (1973 to 1989). In 1,619 patients, the tumor had a lateral site, while in 777 cases, it was situated in the internal/central quadrants. The characteristics of the two groups were well balanced, apart from axillary nodal metastases, which were more frequent for lateral tumors (38.1% v 26.3%). RESULTS Analysis of distant metastases indicated that the regression coefficient associated with tumor site was significant and the hazards ratio estimate was 1.291, which indicates the risk of distant metastases was increased by approximately 30% for internal/central tumors. The analysis of overall survival yielded a significant coefficient and a hazards ratio of 1.192, which indicates an approximately 20% increase of mortality for internal/central tumors. CONCLUSION Early breast cancers situated in central/ internal quadrants have a worse prognosis compared with those in lateral quadrants, in terms of distant metastases and survival. Irradiation of the internal mammary chain for internal/medial tumors could be suggested, but, to date, the therapeutic strategy is still controversial.

12061 Background: Despite life-saving potential, many women struggle to adhere to adjuvant endocrine therapy (AET) for their early-stage, hormone receptor-positive breast cancer. Prior research has demonstrated that emotional distress is a barrier to AET adherence. The current study aimed to test the long-term effects of two 5-week post-surgical group-based stress management interventions, cognitive behavioral therapy (CBT) and relaxation training (RT), versus an attention-matched health education (HE) control on AET adherence at long-term follow-up. Methods: We conducted long-term follow-up (median = 8 years, range = 7-11 years) of a cohort of women who enrolled in a randomized controlled trial of CBT vs. RT vs. HE shortly after surgery for stage 0-3 breast cancer.We measuredadherence with the Endocrine Therapy Medication Usage Questionnaire (ETMUQ) given at long-term follow-up. First, we established adherence factors on the ETMUQ via confirmatory factor analysis. We then used structural equation modeling to regress these factors on study arm, controlling for patient age, stage of disease, and treatments received (chemotherapy/radiation). Results: The sample was predominately middle-aged ( M= 54.81, SD= 10.19), White (41.5%) and Hispanic (42.2%), partnered (62.2%) with stage 1 (57.0%) or stage 2 (25.9%) disease. Of the women who completed long-term follow-up (N = 59, 44.7% of original sample); more than half (n = 30; 50.8%) reported having at least some problems with adherence. There was an effect of intervention group on adherence, such that women receiving RT (n = 15) had significantly better adherence than those receiving CBT (n = 20) on the factor measuring Forgetfulness/Inconsistency ( B(SE) =.57 (.34), p=.001), and marginally better adherence than those receiving CBT on the factor measuring Intentional Nonadherence ( B(SE) =.60 (.33), p =.062). There was no such effect when comparing RT or CBT to HE (n = 24). Conclusions: Women receiving RT were less likely to forget to take their AET and marginally less likely to intentionally miss doses of AET in the long-term compared to women receiving CBT. Future research could investigate the mechanism by which RT may improve adherence. For example, RT may reduce somatic symptoms related to AET or improve a patients’ self-efficacy to cope with these symptoms thereby reducing intentional non-adherence. In addition, RT may improve patients’ attention and awareness leading to less forgetfulness. Clinical trial information: NCT02103387.

Abstract Objective This follow-up study on perceived self-image and psychophysical distress/psychic symptoms was based on a ranomized contolled study of art therapy on women with breast cancer. Method The aim was to examine the long-term effects of time-limited art therapy using the instruments of Structural Analysis of Social Behavior (SASB) and Symptom Check List-90 (SCL-90). Results Three attachment clusters of the SASB showed significant changes post therapy: Autonomous self (cluster 1), Accepting self (cluster 2), and Loving self (cluster 3). Clusters 2 and 3 continued to change in favor of the intervention group at the 5-year follow-up. There were no significant differences in the SCL-90 results between the intervention group and the control group in the follow-up study. Significance of results The art therapy intervention was both therapeutic and psycho-educative. The conclusion of this study is that approaching emotions through time-limited art therapy seems to have a long-lasting effect on the attachment behavioral system shown in the SASB model post intervention, and this effect remained 5 years later.

Background. There are no evidence-based strategies that have been shown to be superior in maintaining motor function for months to years after the stroke. The LAST study therefore intends to assess the effect of a long-term follow-up program for stroke patients compared to standard care on function, disability and health.Design. This is a prospective, multi-site randomised controlled trial, with blinded assessment 18 months after inclusion. A total of 390 patients will be recruited and randomised to a control group, receiving usual care, or to an intervention group 10 to 16 weeks after onset of stroke. Patients will be stratified according to stroke severity, age above 80, and recruitment site. The intervention group will receive monthly coaching on physical activity by a physiotherapist for 18 consecutive months after inclusion.Outcomes. The primary outcome is motor function (Motor Assessment Scale) 18 months after inclusion. Secondary outcomes are: dependency, balance, endurance, health-related quality of life, fatigue, anxiety and depression, cognitive function, burden on caregivers, and health costs. Adverse events and compliance to the intervention will be registered consecutively during follow-up.

Inherited Breast Cancer

Protocols for activity aiming at early diagnosis and treatment of inherited breast or breast-ovarian cancer have been reported. Available reports on outcome of such programmes are considered here. It is concluded that the ongoing activities should continue with minor modifications. Direct evidence of a survival benefit from breast and ovarian screening is not yet available. On the basis of expert opinion and preliminary results from intervention programmes indicating good detection rates for early breast cancers and 5-year survival concordant with early diagnosis, we propose that women at high risk for inherited breast cancer be offered genetic counselling, education in ‘breast awareness’ and annual mammography and clinical expert examination from around 30 years of age. Mammography every second year may be sufficient from 60 years on. BRCA1 mutation carriers may benefit from more frequent examinations and cancer risk may be reduced by oophorectomy before 40–50 years of age. We strongly advocate that all activities should be organized as multicentre studies subjected to continuous evaluation to measure the effects of the interventions on long-term mortality, to match management options more precisely to individual risks and to prepare the ground for studies on chemoprevention.
