OBJECTIVES: To inform the development and evaluation of new blood-based colorectal cancer (CRC) screening tests satisfying minimum United States (US) coverage criteria, we estimated the impact of the different test performance characteristics on long-term testing benefits and burdens. METHODS: A novel CRC-Microsimulation of Adenoma Progression and Screening (CRC-MAPS) model was developed, validated, then used to assess different screening tests for CRC. We compared multiple, hypothetical blood-based CRC screening tests satisfying minimum coverage criteria of 74% CRC sensitivity and 90% specificity, to measure how changes in a test's CRC sensitivity, specificity, and adenoma sensitivity (sizes 1-5 mm, 6-9 mm, ≥10 mm) affect total number of colonoscopies (COL), CRC incidence reduction (IR), CRC mortality reduction (MR), and burden-to-benefit ratios (incremental COLs per percentage-point increase in IR or MR)...

As cancer is overtaking cardiovascular disease as the leading cause of death among diabetics, improved cancer prevention efforts are needed for individuals with diabetes. In this research letter, we used data from the US National Health Interview Survey to examine the use of screening for two major diabetes-related cancers, colorectal cancer, and breast cancer, in individuals with and without diabetes. We found that individuals with diabetes had slightly higher use of colorectal cancer screening and similar use of breast cancer screening compared to those without diabetes in the US...

OBJECTIVE: A rolling circle amplification (RCA) based commercial methodology using cell-free (cf)DNA to screen for common trisomies became available in 2018. Relevant publications documented high detection but with a higher than expected 1% false positive rate. Preliminary evidence suggested assay variability was an issue. A multi-center collaboration was created to explore this further and examine whether subsequent manufacturer changes were effective. METHODS: Three academic (four devices) and two commercial (two devices) laboratories provided run date, chromosome 21, 18, and 13 run-specific standard deviations, number of samples run, and reagent lot identifications...

OBJECTIVES: Hemoglobinopathies are the commonest inherited blood disorders and form a serious burden worldwide, affecting communities, patient quality of life and healthcare resources. The Kingdom of Bahrain has issued a law obligating couples to undergo premarital screening to detect those at risk of having children affected with these disorders. The aim of this study was to analyze the marital decisions of couples at risk for hemoglobinopathies and follow up the outcomes. METHODS: A retrospective study was conducted on couples at risk for hemoglobinopathies identified during the premarital screening program at local health centers in the Kingdom of Bahrain and referred to the genetics department in the Salmaniya Medical Complex for genetic counselling in 2018-2020...

Many factors need to be considered when planning and managing a screening programme for the early detection of cervical cancer (CC). A non-systematic international review of the organisation of CC screening using high-risk human papillomavirus (HPV-HR) testing, aimed at identifying the organisational methods of these programmes, was conducted with a view to supporting the future of the French system in the context of the transition to HPV-HR testing. In countries where HPV testing has been implemented or planned, the initial reflection process has provided an opportunity to rethink the previous (cytological) screening organisation...

OBJECTIVES: Unconjugated estriol (uE3) is used as a marker for fetal aneuploidy in maternal serum screening tests. The goal of this study was to examine the validity of a new immunoassay for uE3 that uses a monoclonal antibody (m-uE3) rather than the more commonly used polyclonal antibody (p-uE3). SETTING: Assays were performed in the Special Chemistry laboratory at Women and Infants Hospital of Rhode Island. METHODS: Residual fresh ( n  = 100) and frozen ( n  = 533) second trimester serum samples from routine clinical care were tested using p-uE3 and/or m-uE3 assays...

OBJECTIVE: To achieve the lung cancer screening (LCS) mortality benefit in clinical trials, timely, real-world follow-up of abnormal test results is necessary. Presently, annual LCS rates are lower than in trials, and adherence to follow-up after suspicious findings has not been well studied. This study examined timely adherence to follow-up recommendations after positive low-dose computed tomography (LDCT) screenings. METHODS: This retrospective study included individuals from two academic primary care practices in New York City who met United States Preventative Services Task Force LCS eligibility and had a positive LDCT scan between 2013 and 2020...

OBJECTIVES: Organized breast cancer screening may not achieve its full potential due to organizational and cultural barriers. In Italy, two identified barriers were low attendance in Southern Italy and, in Italy as a whole, underscreening and overscreening in parts of the eligible population. The objective of this study was to identify potential changes to overcome these barriers and to quantify their costs and effects. METHODS: To assess the impact of potential measures to improve breast cancer screening in Italy, we performed an evaluation of costs and effects for increasing adherence for Southern Italy and harmonizing screening intervals (biennial screening) for the whole of Italy, using an online tool (EU-TOPIA evaluation tool) based on the MIcrosimulation SCreening ANalysis (MISCAN) model...

OBJECTIVES: When evaluating potential new cancer screening modalities, estimating sensitivity, especially for early-stage cases, is critical. There are methods to approximate stage-specific sensitivity in asymptomatic populations, both in the prospective (active screening) and retrospective (stored specimens) scenarios. We explored their validity via a simulation study. METHODS: We fit natural history models to lung and ovarian cancer screening data that permitted estimation of stage-specific (early/late) true sensitivity, defined as the probability subjects screened in the given stage had positive tests...
