Overdiagnosis

PURPOSE OF REVIEW: To review recent publications on the inability to belch syndrome. RECENT FINDINGS: Five recent retrospective case series indicate that the inability to belch syndrome usually starts in early childhood and is often accompanied by gurgling noises in the chest, pain in the chest or upper abdomen, bloating, and excessive flatulence. Currently, the vast majority of patients who have been identified with inability to belch have self-diagnosed the syndrome on the basis of information available on the internet...

This article introduces a series of articles covering some of the most important aspects of contemporary prostate cancer care. After the introduction of the prostate-specific antigen (PSA) blood test and systematic prostate biopsies in the early 1990s, the incidence of localised prostate cancer and the use of radical treatment rose dramatically. Improved diagnostic methods and understanding of the tumour biology now reduce overdiagnosis and pave the way for organised screening. New and more effective treatments, in combination with the stage shift from advanced to localised disease at the time of diagnosis, have reduced the age-standardised prostate cancer specific mortality by half in men under the age of 85 years...

Pulmonary embolism (PE) is a common disease, which can present with a variety of symptoms. Optimal use of diagnostics is challenging given the tight and delicate balance between underdiagnosis and over-testing or overdiagnosis. Diagnostic delay occurs in a substantial part of patients, and seems more common in those with known cardiopulmonary disease or non-specific signs and symptoms. At the other end of the spectrum, the amount of diagnostic imaging increases. Increased use of diagnostic imaging in general leads to more harmful exposures and might result in overtreatment, as may be the case in subsegmental PE...

OBJECTIVES: Blood pressure (BP) is the leading global cause of mortality, and its prevalence is increasing in children and adolescents. Aortic BP is lower than brachial BP in adults. We aimed to assess the extent of this difference and its impact on the diagnosis of hypertension among adolescents. METHODS: We used data from 3850 participants from a UK cohort of births in the early 1990s in the Southwest of England, who attended their ∼17-year follow-up and had valid measures of brachial and aortic BP at that clinic [mean (SD) age 17...

Breast cancer is the most frequently diagnosed cancer in women accounting for about 30% of all new cancer cases and the incidence is constantly increasing. Implementation of mammographic screening has contributed to a reduction in breast cancer mortality of at least 20% over the last 30 years. Screening programs usually include all women irrespective of their risk of developing breast cancer and with age being the only determining factor. This approach has some recognized limitations, including underdiagnosis, false positive cases, and overdiagnosis...

BACKGROUND: Increasing melanoma incidence with less increasing mortality is observed in several countries. This discrepancy is not well understood. OBJECTIVE: In this study, our aim was to discuss factors (UV exposure, melanoma treatment, diagnostic activity, overdiagnosis, pathologists' diagnostic threshold and clinicians' propensity to remove suspect skin lesions) that may influence melanoma incidence and mortality in Denmark. METHODS: This was a register study with the number of melanocyte-related lesions and melanoma mortality based on comprehensive national pathology and mortality databases for the period 1999-2019...

Prostate-specific antigen (PSA) based screening is controversial, even though randomised trials show that screening can reduce prostate cancer mortality. The main reason is that screening leads to overdiagnosis of indolent cancers that would never have surfaced clinically in the absence of screening. Recently, several large studies have shown that magnetic resonance imaging (MRI) improves prostate cancer diagnostics. With MRI, up to half of all men with elevated PSA values can be spared a biopsy. When a biopsy is needed, the needles can be directed towards the suspicious area in the prostate, which increases the detection of clinically significant tumors...

Multiple, accelerating and interacting ecological crises are increasingly understood as constituting a major threat to human health and well-being. Unconstrained economic growth is strongly implicated in these growing crises, and it has been argued that this growth has now become "uneconomic growth", which is a situation where the size of the economy is still expanding, but this expansion is causing more harm than benefit. This article summarises the multiple pathways by which uneconomic growth can be expected to harm human health...

OBJECTIVE: This work aims to examine the latest evidence on the impact of pre-biopsy MRI, in addition to prostate-specific antigen (PSA) testing, on health outcomes and quality of life. METHODS: We conducted a literature search including PubMed and Cochrane Central Register of Controlled Trials (CENTRAL) databases, with a limited scan of (i) guidelines and (ii) references from trial reports, from January 2005 to 25th January 2023. Two independent reviewers selected randomised controlled trials (RCT) and cohort studies which met our inclusion criteria...

OBJECTIVE: To investigate the clinical feature, pathological morphology, special histopathological subtype and immunohistochemical characteristic of gonadoblastoma. METHODS: Three patients of gonadoblastoma treated from 2014 to 2020 were enrolled, and the clinical characteristics, histological morphology and immunophenotype were analyzed, and the literatures were also reviewed. RESULT: Three phenotypical females were 14,17 and 27 years old...

BACKGROUND: Prostate cancer (PCa) and benign prostatic hyperplasia (BPH) are prevalent conditions affecting a significant portion of the male population, particularly with advancing age. Traditional diagnostic methods, such as digital rectal examination (DRE) and prostate-specific antigen (PSA) tests, have limitations in specificity and sensitivity, leading to potential overdiagnosis and unnecessary biopsies. SIGNIFICANCE: This study explores the effectiveness of 1 H NMR urine metabolomics in distinguishing PCa from BPH and in differentiating various PCa grades, presenting a non-invasive diagnostic alternative with the potential to enhance early detection and patient-specific treatment strategies...

BACKGROUND: Prostate cancer (PCa) is one of the most frequently occurring malignancies. Although most cases are not life-threatening, approximately 20% endure an unfavorable outcome. PSA-based screening reduced mortality but at the cost of an increased overdiagnosis/overtreatment of low-risk (lrPCa) and favorable intermediate-risk (firPCa) PCa. PCa risk-groups are usually identified based on serum Prostate-Specific Antigen (PSA), the Gleason score, and clinical T stage, which have consistent although variable specificity or subjectivity...

Current prostate carcinoma (PCa) biomarkers, including total prostate-specific antigen (tPSA), have unsatisfactory diagnostic sensitivity and specificity resulting in overdiagnosis and overtreatment. Previously, we described an optimised bias-based preamplification-digital droplet PCR (OBBPA-ddPCR) technique, which detects tumour DNA in blood-derived cell-free DNA (cfDNA) of cancer patients. The current study investigated the performance of newly developed OBBPA-ddPCR-based biomarkers. Blood plasma samples from healthy individuals ( n = 90, controls) and PCa ( n = 39) and benign prostatic hyperplasia patients (BPH, n = 40) were analysed...

Thyroid cancer (TC) is the most common endocrine cancer. The increase in thyroid cancer incidence has been observed in both developed and developing countries in different Geographical and climate areas The share of thyroid cancer drastically increased during the last decades in Georgia and ranked as the second most prevalent cause of cancer among women. Although for addressing the burden of cancer, important steps were taken by the State during the last decades, the burden of this disease is still significant...

PURPOSE: To assess the role of contrast-enhanced mammography (CEM) in predicting the malignancy of breast calcifications. MATERIAL AND METHODS: We retrospectively evaluated patients with suspicious calcifications (BIRADS 4) who underwent CEM and stereotactic vacuum-assisted biopsy (VAB) at our institution. We assessed the sensitivity (SE), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) of CEM in predicting malignancy of microcalcifications with a 95% confidence interval; we performed an overall analysis and a subgroup analysis stratified into group A-low risk (BIRADS 4a) and group B-medium/high risk (BIRADS 4b-4c)...

PURPOSE: Diagnostic accuracy of autism spectrum disorder (ASD) is crucial to track and characterize ASD, as well as to guide appropriate interventions at the individual level. However, under-diagnosis, over-diagnosis, and misdiagnosis of ASD are still prevalent. METHODS: We describe 232 children (MAge = 10.71 years; 19% female) with community-based diagnoses of ASD referred for research participation. Extensive assessment procedures were employed to confirm ASD diagnosis before study inclusion...

Background : Effective pre-surgical planning is crucial for achieving successful outcomes in endocrine surgery: it is essential to provide patients with a personalized plan to minimize operative and postoperative risks. Methods: Preoperative lymph node (LN) mapping is a structured high-resolution ultrasonography examination performed in the presence of two endocrinologists and the operating surgeon before intervention to produce a reliable "anatomical guide". Our aim was to propose a preoperative complete model that is non-invasive, avoids overdiagnosis of thyroid microcarcinomas, and reduces medical expenses...

In recent years, there has been an increase in the prevalence of the diagnosis of attention-deficit/hyperactivity disorder (ADHD), a cognitive and behavioral disorder in which individuals present with inattention and impulsivity, in the pediatric population. With an increase in diagnoses, there is also increasing concern regarding overdiagnosis and overtreatment with medications for ADHD. The objective of this study was to map out and compile the recent literature pertaining to alternative therapies (e.g., physical activity, diet, mindfulness, and computer-based interventions) for children and adolescents diagnosed with ADHD in an attempt to reduce or replace the use of pharmacological therapy...

Cotyledonoid dissecting leiomyoma (CDL) is a rare variant of uterine leiomyoma. The tumor is benign, but the appearance and growth pattern are unusual and alarming. Disseminated peritoneal leiomyomatosis (DPL) is another rare tumor that can mimic malignancy. The occurrence of these two tumors in a single case is even rarer and has not been found in the literature to the best of our knowledge. We report a case of CDL with DPL in a 43-year-old Nepalese woman who presented with abdominal pain and per vaginal bleeding...

Sometimes non-neoplastic changes of the gastric mucosa mimic diffuse-type gastric carcinoma, specifically signet-ring cell adenocarcinoma. In fact, gastric epithelial cells undergoing signet-ring cell change have a cellular morphology that is almost identical to signet-ring cell adenocarcinoma, often leading to misdiagnosis. Accurate recognition of signet-ring cell change is essential to avoid overdiagnosis and overtreatment of signet-ring cell adenocarcinoma. Research on this topic is limited and clinicians lack formal diagnostic tools when signet-ring cells are detected in biopsy specimens...
