Quality of life of women with a screen-detected versus clinically detected breast cancer in the Netherlands: a prospective cohort study.

Purpose: Breast cancer (BC) screening enables early detection of BC, which may lead to improved quality of life (QoL). We aim to compare QoL between women with a screen-detected and clinically detected BC in the Netherlands.

Methods: We used data from the 'Utrecht cohort for Multiple BREast cancer intervention studies and Long-term evaluation' (UMBRELLA) between October 2013 and March 2022.

Risk assessment tools for bleeding in patients with unprovoked venous thromboembolism: an analysis of the PLATO-VTE study.

Background: Guidelines suggest indefinite anticoagulation after unprovoked venous thromboembolism (VTE) unless the bleeding risk is high, yet there is no consistent guidance on assessing bleeding risk.

Objectives: This study aimed to evaluate the performance of 5 bleeding risk tools (RIETE, VTE-BLEED, CHAP, VTE-PREDICT, and ABC-Bleeding).

Methods: PLATO-VTE, a prospective cohort study, included patients aged ≥40 years with a first unprovoked VTE.

The prognostic potential of mammographic growth rate of invasive breast cancer in the Nijmegen breast cancer screening cohort.

Objectives: Insight into the aggressiveness of potential breast cancers found in screening may optimize recall decisions. Specific growth rate (SGR), measured on mammograms, may provide valuable prognostic information. This study addresses the association of SGR with prognostic factors and overall survival in patients with invasive carcinoma of no special type (NST) from a screened population.

Method of primary breast cancer detection and the disease-free interval, adjusting for lead time.

Background: Little is known about the impact of screen-detected breast cancer compared with clinically detected breast cancer on the disease-free interval (ie, free from locoregional recurrences, distant metastasis, contralateral breast cancer). Moreover, it is thought that most studies overestimate the beneficial effect of screening, as they do not adjust for lead time. We investigated the association between method of breast cancer detection and disease-free interval, taking lead time into account.

Long-term cause of death patterns and mode of breast cancer detection in The Netherlands, 2004-2019.

Objective: Early detection through mammographic screening and various treatment modalities of cancer may have changed life expectancy and cause-specific mortality of breast cancer patients. We aimed to determine the long-term cause of death patterns in screening-detected patients and clinically diagnosed patients in the Netherlands compared with the general population.

Methods: Using data from the Netherlands Cancer Registry and Statistics Netherlands of around 26,000 women, aged 50-75 at diagnosis and surgically treated for invasive breast cancer in 2004-2008, we compared patients with screening-detected and clinically diagnosed cancer for major causes of death until 2020.

Engineering the methylotrophic yeast for lactate production from methanol.

Lactate has gained increasing attention as a platform chemical, particularly for the production of the bioplastic poly-lactic acid (PLA). While current microbial lactate production processes primarily rely on the use of sugars as carbon sources, it is possible to envision a future where lactate can be produced from sustainable, non-food substrates. Methanol could be such a potential substrate, as it can be produced by (electro)chemical hydrogenation from CO.

Cumulative risks of false positive recall and screen-detected breast cancer after multiple screening examinations.

Women tend to make a decision about participation in breast cancer screening and adhere to this for future invitations. Therefore, our study aimed to provide high-quality information on cumulative risks of false-positive (FP) recall and screen-detected breast cancer over multiple screening examinations. Individual Dutch screening registry data (2005-2018) were gathered on subsequent screening examinations of 92 902 women age 49 to 51 years in 2005.

Research in Action-Students' Perspectives on the Integration of Research Activities in Undergraduate Biomedical Curricula.

We describe and evaluate our practice-based learning approach for research in undergraduate students studying Biomedical Sciences at Radboud University Nijmegen, the Netherlands. First-year students who started their study between 2015 and 2018 actively participated in data collection and measurements, including anthropometry, electrocardiogram findings, genetic variants, and lifestyle habits. All data were entered into one anonymous database which was used by students to analyze their research questions.

Detection and interval cancer rates during the transition from screen-film to digital mammography in population-based screening.

Background: Between 2003 and 2010 digital mammography (DM) gradually replaced screen-film mammography (SFM) in the Dutch breast cancer screening programme (BCSP). Previous studies showed increases in detection rate (DR) after the transition to DM. However, national interval cancer rates (ICR) have not yet been reported.

Growth rate of invasive ductal carcinomas from a screened 50-74-year-old population.

Objective As breast cancer growth rate is associated with menopause, most screening programmes target mainly women aged 50-74. We studied the association between age at diagnosis and growth rate in this screening-specific age range. Methods We used data from breast cancer patients diagnosed in the screening programme in Nijmegen, the Netherlands.

Towards personalized screening: Cumulative risk of breast cancer screening outcomes in women with and without a first-degree relative with a history of breast cancer.

Several reviews have estimated the balance of benefits and harms of mammographic screening in the general population. The balance may, however, differ between individuals with and without family history. Therefore, our aim is to assess the cumulative risk of screening outcomes; screen-detected breast cancer, interval cancer, and false-positive results, in women screenees aged 50-75 and 40-75, with and without a first-degree relative with a history of breast cancer at the start of screening.

Predicting the stage shift as a result of breast cancer screening in low- and middle-income countries: a proof of concept.

Objective: To provide proof of concept for a simple model to estimate the stage shift as a result of breast cancer screening in low- and middle-income countries (LMICs). Stage shift is an essential early detection indicator and an important proxy for the performance and possible further impact of screening programmes. Our model could help LIMCs to choose appropriate control strategies.

Breast cancer among women over 75 years: an important public health problem?

Women aged >75 years are not invited for mammographic screening; if diagnosed with breast cancer, due to their anticipated short-life expectancy, they are expected to die of other causes. To describe the breast cancer health problem in women aged >75 years, we estimated breast cancer incidence in this age group and the risk of breast cancer death in patients diagnosed after 75 years of age in Nijmegen, the Netherlands. Our findings demonstrate that in this age group, 3.

Dutch digital breast cancer screening: implications for breast cancer care.

Background: In comparison to other European population-based breast cancer screening programmes, the Dutch programme has a low referral rate, similar breast cancer detection and a high breast cancer mortality reduction. The referral rate in the Netherlands has increased over time and is expected to rise further, mainly following nationwide introduction of digital mammography, completed in 2010. This study explores the consequences of the introduction of digital mammography on the balance between referral rate, detection of breast cancer, diagnostic work-up and associated costs.

Mammography screening and risk of breast cancer death: a population-based case-control study.

Background: Because the efficacy of mammography screening had been shown in randomized controlled trials, the focus has turned on its effectiveness within the daily practice. Using individual data of women invited to screening, we conducted a case-control study to assess the effectiveness of the Dutch population-based program of mammography screening.

Methods: Cases were women who died from breast cancer between 1995 and 2003 and were closely matched to five controls on year of birth, year of first invitation, and number of invitations before case's diagnosis.

Effective biennial mammographic screening in women aged 40-49.

Background: The United Kingdom is currently moving the age limit for invitation in its national breast screening programme downwards from 50 to 47. In contrast, the US Preventive Services Task Force concluded that, because of borderline statistical significance on effectiveness of mammographic screening, the current evidence is insufficient to advise screening in women aged 40-49.

Material And Methods: We designed a case-referent study to investigate the effect of biennial mammographic screening on breast cancer mortality for women in their forties.

Life expectancy of screen-detected invasive breast cancer patients compared with women invited to the Nijmegen screening program.

Background: Screening can lead to earlier detection of breast cancer and thus to an improvement in survival. The authors studied the life expectancy of women with screen-detected invasive breast cancer (patients) compared with women invited to the breast cancer screening program in Nijmegen, the Netherlands (comparison group).

Methods: Each patient diagnosed between 1975 and 2006 was randomly age-matched with a woman invited in the same calendar year and free from breast cancer at the time of diagnosis of the patient.

Impressive time-related influence of the Dutch screening programme on breast cancer incidence and mortality, 1975-2006.

The aim of this study was to assess changes in the trends in breast cancer mortality and incidence from 1975 to 2006 among Dutch women, in relation to the implementation of the national breast cancer screening programme. Screening started in 1989 for women aged 50-69 and was extended to women aged 70-75 years in 1998 (attendance rate approximately >80%). A joinpoint Poisson regression analysis was used to identify significant changes in rates over time.

Personality factors and breast cancer risk: a 13-year follow-up.

Consistent scientific evidence on the possible relationship between psychologic variables and breast cancer development is lacking. In 1996, our group first reported on the present prospective, longitudinal study. We found a weak association between a high score on the antiemotionality scale (indicating an absence of emotional behavior or a lack of trust in one's own feelings) and the development of breast cancer.

Effect of soft-copy display supported by CAD on mammography screening performance.

Diagnostic performance and reading speed for conventional mammography film reading is compared to reading digitized mammograms on a dedicated workstation. A series of mammograms judged negative at screening and corresponding priors were collected. Half were diagnosed as cancer at the next screening, or earlier for interval cancers.

Effect of recall rate on earlier screen detection of breast cancers based on the Dutch performance indicators.

Background: The recall rate (i.e., the rate at which mammographically screened women are recalled for additional assessment) in the Dutch breast screening program (0.

Computer-aided detection versus independent double reading of masses on mammograms.

Purpose: To evaluate the use of a computer-aided detection (CAD) system (designed for mammographic mass detection) to help improve mass interpretation and to compare CAD results with independent double-reading results.

Materials And Methods: Screening mammograms from 500 cases were collected; 125 of these cases were screening-detected cancers, and 125 were interval cancers. Previously obtained screening mammograms (ie, prior mammograms) were available in all cases.
