Overdiagnosis in breast cancer screening is an important issue. A recent study from Denmark concluded that one in three breast cancers diagnosed in screening areas in women aged 50-69 years were overdiagnosed. The purpose of this short communication was to disentangle the study's methodology in order to evaluate the soundness of this conclusion. We found that both the use of absolute differences as opposed to ratios; the sole focus on non-advanced tumours and the crude allocation of tumours and person-years by screening history for women aged 70-84 years, all contributed to the very high estimate of overdiagnosis...

BACKGROUND: Two key issues in prostate cancer (PCa) that demand attention currently are the need for a more precise and minimally invasive screening test owing to the inaccuracy of prostate-specific antigen and differential diagnosis to distinguish advanced vs. indolent cancers. This continues to pose a tremendous challenge in diagnosis and prognosis of PCa and could potentially lead to overdiagnosis and overtreatment complications. Copy number variations (CNVs) in the human genome have been linked to various carcinomas including PCa...

Previous studies showed that general practitioners have problems in diagnosing asthma accurately, resulting in both under and overdiagnosis. To support general practitioners in their diagnostic process, an asthma diagnostic consultation service was set up. We evaluated the performance of this asthma diagnostic consultation service by analysing the (dis)concordance between the general practitioners working hypotheses and the asthma diagnostic consultation service diagnoses and possible consequences this had on the patients' pharmacotherapy...

INTRODUCTION: COPD under-diagnosis is common in Primary Health Care medicine, due to the low use of spirometry, but there is less information about over-diagnosis of the disease in patients that have a clinical diagnosis of COPD. OBJECTIVE: The main objective of the study was to investigate the prevalence of COPD over-diagnosis in Primary Care medicine. Secondary objectives were to determine the factors associated with an incorrect clinical diagnosis of COPD and to analyse whether the pharmacological treatment is different for patients with correct or incorrect diagnosis...

The 4Kscore® Test (BioReference Laboratories, Elmwood Park, NJ) is a blood test that accurately determines the risk of aggressive prostate cancer and significantly reduces prostate biopsies and associated overdiagnosis and overtreatment of indolent cancer. A budget impact model was developed to test the hypothesis that the 4Kscore Test can improve quality of care and deliver cost savings for patients who are suspected of having prostate cancer and would otherwise undergo prostate biopsy under the current standard of care (SOC) in the United States...

Importance: Potential survival benefits from treating aggressive (Gleason score, ≥7) early-stage prostate cancer are undermined by harms from unnecessary prostate biopsy and overdiagnosis of indolent disease. Objective: To evaluate the a priori primary hypothesis that combined measurement of PCA3 and TMPRSS2:ERG (T2:ERG) RNA in the urine after digital rectal examination would improve specificity over measurement of prostate-specific antigen alone for detecting cancer with Gleason score of 7 or higher...

Importance: No guidelines exist currently for guideline panels and others considering changes to disease definitions. Panels frequently widen disease definitions, increasing the proportion of the population labeled as unwell and potentially causing harm to patients. We set out to develop a checklist of issues, with guidance, for panels to consider prior to modifying a disease definition. Observations: We assembled a multidisciplinary, multicontinent working group of 13 members, including members from the Guidelines International Network, Grading of Recommendations Assessment, Development and Evaluation working group, and the World Health Organisation...

OBJECTIVES: To determine whether color Doppler sonography increases the detection of pregnancies at risk for adverse outcomes. METHODS: Participants admitted to labor and delivery with the anticipation of a vaginal delivery underwent measurements of amniotic fluid volume (AFV) using amniotic fluid index (AFI) and single deepest pocket (SDP) techniques by grayscale followed by color Doppler sonography. Oligohydramnios was defined as an AFI of less than 5 cm or an SDP of less than 2 cm...

BACKGROUND: Survival of childhood, adolescent and young adult (CAYA) cancers has increased with progress in the management of the treatments and has reached more than 80% at 5 years. Nevertheless, these survivors are at great risk of second cancers and non-malignant co-morbidities in later life. DeNaCaPST is a non-interventional study whose aim is to organize a national screening for thyroid cancer and breast cancer in survivors of CAYA cancers. It will study the compliance with international recommendations, with the aim, regarding a breast screening programme, of offering for every woman living in France, at equal risk, an equal screening...

Appropriate diagnosis is fundamental in medicine because it sets the basis for the prediction of disease outcome at the single patient level (prognosis) and decisions regarding the most appropriate therapy. However, given the large series of social, clinical and biological factors that determine the likelihood of an individual's future outcome, prognosis only partly depends on diagnosis and aetiology and treatment is not decided solely on the basis of the underlying diagnosis. This issue is crucial in multifactorial diseases like atherosclerosis, where the use of statins has now shifted from 'treating hypercholesterolaemia' to 'treating the risk of adverse cardiovascular events'...

Thyroid nodules are common and their incidence has increased due to various factors. Systematic approach to the work-up of thyroid nodules is necessary to decrease overdiagnosis as well as over treatment. Applying the trifecta of history, physicial examination and high-resolution ultrasound (HRUS) as well as fine needle aspiration biopsy (FNAB) with added TSH measurement is important in the work-up. HRUS is a central part in the diagnostic approach, being able to risk classify nodules and selecting nodules for FNAB...

The use of circulating tumour DNA to screen for cancer in asymptomatic individuals is the goal of Grail, initially set up by Illumina. This company is now raising a large amount of capital to develop this project on a much longer time scale than initially announced. Although it has access to cutting edge technology and is led by excellent scientists, the prospect for success in this application is rather bleak, mainly because of the extreme requirements for specificity in order to avoid overdiagnosis.

REVIEW
E Wolter, A Neumann, W Straff
Besides effect and environmental monitoring, human biomonitoring (HBM) offers an attractive method for analyzing the distribution and intensity of anthropogenic environmental pollutants in individuals or in particular groups of the population. However, no assessment values of comparable reliability are available to enable an interpretation of the results of environmental studies from the viewpoint of environmental health. This must be taken into account when reporting findings of such studies as well as in medical consultation, in order to avoid overdiagnosis and unnecessary anxiety for the participant...

Importance: The incidence of thyroid cancer detection has increased by 4.5% per year over the last 10 years, faster than for any other cancer, but without a corresponding change in the mortality rate. In 2013, the incidence rate of thyroid cancer in the United States was 15.3 cases per 100 000 persons. Most cases of thyroid cancer have a good prognosis; the 5-year survival rate for thyroid cancer overall is 98.1%. Objective: To update the US Preventive Services Task Force (USPSTF) recommendation on screening for thyroid cancer...

The incidence of patients diagnosed with primary malignant cardiac tumors (PMCTs) has increased greatly in the past few decades. Whether this rising prevalence is due to overdiagnosis or an increased malignancy rate of primary cardiac tumors (PCTs) remains unclear. Therefore, we performed a systematic review and meta-analysis of published retrospective studies to determine whether the malignancy rate has been increasing over time. Published studies containing relevant data between 1956 and 2014 were evaluated...
