Importance: Thyroid cancer generally grows at a very slow rate in adults, and overdiagnosis is a global issue. However, the detection of early-stage thyroid cancer by screening is not well described in young patients. To prevent overdiagnosis, it is essential to understand the natural course of thyroid cancer growth detection by ultrasonography screening in young patients. Objective: To evaluate the natural progression of thyroid cancer in young patients. Design, Setting, and Participants: An observational study evaluated changes in the diameter of malignant or suspected malignant thyroid tumors on 2 occasions...

Screening has been always considered as a double-edged sword. Cancer screening could save lives in some cases, however, in other cases, it might also turn people into overdiagnosis. Overdiagnosis is the diagnosis of cancer that will never cause symptoms or death during a patient's lifetime. Therefore, overdiagnosis might lead to unnecessary treatments and lifetime surveillance, and then increase economic burden and psychological burden. In this review, we focus on how to correctly evaluate the overdiagnosis rate, and how to avoid or reduce the harms caused by overdiagnosis in the future according to the reasons associated with overdiagnosis...

Malika Gupta, Amanda Cox, Anna Nowak-Węgrzyn, Julie Wang
Food allergy diagnosis remains challenging. Most standard methods are unable to differentiate sensitization from clinical allergy. Recognizing food allergy is of utmost importance to prevent life-threatening reactions. On the other hand, faulty interpretation of tests leads to overdiagnosis and unnecessary food avoidances. Highly predictive models have been established for major food allergens based on skin prick testing and food-specific immunoglobulin E but are lacking for most other foods. Although many newer diagnostic techniques are improving the accuracy of food allergy diagnostics, an oral food challenge remains the only definitive method of confirming a food allergy...

Background: Overdiagnosis is the main harm of cancer screening programs but is difficult to quantify. This review aims to evaluate existing approaches to estimate the magnitude of overdiagnosis in cancer screening in order to gain insight into the strengths and limitations of these approaches and to provide researchers with guidance to obtain reliable estimates of overdiagnosis in cancer screening. Methods: A systematic review was done of primary research studies in PubMed that were published before January 1, 2016, and quantified overdiagnosis in breast cancer screening...

Cervical low-grade squamous intraepithelial lesions (LSIL) (aka cervical intraepithelial neoplasia, grade 1 [CIN1]) can present considerable diagnostic challenges and are associated with poor interobserver reproducibility and overdiagnosis. Furthermore, ancillary studies such as p16 immunohistochemistry have shown little utility in resolving the LSIL versus negative/reactive differential. Human papillomavirus (HPV) RNA in situ hybridization (ISH) has shown promise as a diagnostic aid in this setting, but has not been studied in a large case series...

Background: The Acute Dialysis Quality Initiative (ADQI) XI Workgroup has suggested defining heart failure (HF) in patients with end-stage renal disease by the presence of at least one out of eight predefined echocardiographic criteria. Given the high prevalence of echocardiographic alterations in chronic kidney disease (CKD) patients, we hypothesized that application of echocardiographic ADQI criteria will result in overdiagnosis of HF, without providing substantial prognostic information...

Statistical models of breast cancer tumour progression have been used to further our knowledge of the natural history of breast cancer, to evaluate mammography screening in terms of mortality, to estimate overdiagnosis, and to estimate the impact of lead-time bias when comparing survival times between screen detected cancers and cancers found outside of screening programs. Multi-state Markov models have been widely used, but several research groups have proposed other modelling frameworks based on specifying an underlying biological continuous tumour growth process...

Globally, breast cancer is both the most commonly occurring cancer and the commonest cause of cancer death among women. Available data suggest that incidence and mortality in high-resource countries has been declining whereas incidence and mortality in low-resource countries has been increasing. This pattern is likely to be due to changing risk factor profiles and differences in access to breast cancer early detection and treatment. Risk factors for breast cancer include increasing age, race, menarche history, breast characteristics, reproductive patterns, hormone use, alcohol use, tobacco use, diet, physical activity, and body habitus...

OBJECTIVE: The discovery of breast cancer at earlier stages with screening brings the risk that some cancers will be overdiagnosed or overtreated. Reasonable estimates show the overdiagnosis rate due to screening mammography to be low, 1-10%. CONCLUSION: Overdiagnosis should not be used as a reason to delay the onset or decrease the frequency of screening, because neither strategy will decrease overdiagnosis. Improvements in personalized treatment will diminish the morbidity of treatment and, therefore, the significance of overdiagnosis...

BACKGROUND: To investigate the relationship between endoscopic and esophageal manometric hiatus hernia (HH). METHODS: Forty-six gastroesophageal reflux disease patients with endoscopic HH under maintenance therapy were recruited. Endoscopy was performed on all patients in a fully conscious state. Endoscopic HH was defined as apparent separation greater than 1 cm of the lower margin of the esophageal palisade vessels and the diaphragm hiatus on endoscopy under deep inspiration...

Ductal or lobular carcinoma in situ (DCIS/LCIS) can rarely arise from sclerosing adenosis (SA). The combination of cytologically malignant cells and the infiltrative growth pattern may make it challenging to distinguish it from an invasive carcinoma. The authors reviewed 50 consecutive cases of CIS involving SA to seek the salient histologic characteristics in order to prevent overdiagnosis. The features commonly seen with CIS were the lobular configuration at low magnification (94%), uninvolved SA in neighboring tissue (84%), at least focally identifiable myoepithelial cells on H&E-stained sections (76%), separate foci of unequivocal CIS (58%), associated microcalcifications (54%), and hyaline basement membrane surrounding tumor cell nests (48%)...

BACKGROUND: Overdiagnosis among clinically detected lung cancers likely consists of cases that are non-aggressive and slowly progressive and will never disseminate, cause symptoms or be a threat to a subject's survival, even if untreated. In this study, we estimate the prevalence of non-aggressive lung cancers from a large, population-based cancer registry. METHODS: We identified individuals ≥65 years with histologically confirmed, untreated stage I non-small cell lung cancers (NSCLCs) from the Surveillance, Epidemiology, and End Results-Medicare registry...

BACKGROUND: Concerns have been expressed about asthma overdiagnosis. The UK National Institute of Health and Care Excellence (NICE) proposed a new diagnostic algorithm applying four lung function measures sequentially (ratio of forced expiratory volume in 1 s [FEV1] to forced vital capacity [FVC] <70%, bronchodilator reversibility ≥12%, fractional exhaled nitric oxide [FeNO] ≥35 parts per billion, and peak expiratory flow variability >20%). We aimed to assess the diagnostic value of three of the tests individually, and then test the proposed algorithm in symptomatic children...

A non-smoking man in his seventh decade presented with a lesion he had had for about 5 years on the right external surface of the lip 1 mm from the vermilion border. On physical examination, a yellowish-coloured, non-tender, verrucous mass of 0.5 × 0.7 cm was observed. A histopathological examination of the first 3-mm punch biopsy was non-diagnostic. The histopathological evaluation of a second, 5-mm-deep punch biopsy made by a pathology expert in oral lesions revealed a diagnosis of verruciform xanthoma. The key to the diagnosis of verruciform xanthoma is to recognize xanthoma cells...

Our use of modern cardiovascular imaging tools has not kept pace with their technological development. Diagnostic errors are common but seldom investigated systematically. Rather than more impressive pictures, our main goal should be more precise tests of function which we select because their appropriate use has therapeutic implications which in turn have a beneficial impact on morbidity or mortality. We should practise analytical thinking, use checklists to avoid diagnostic pitfalls, and apply strategies that will reduce biases and avoid overdiagnosis...

PURPOSE OF REVIEW: Active surveillance is an established treatment option for men with localized, low-risk prostate cancer (CaP). It entails the postponement of immediate therapy with the option of delayed intervention upon disease progression. The rate of clinical progression and need for treatment on active surveillance is approximately 50% over 15 years. The present review summarizes recent data on current methods, attempting to prevent clinical progression. RECENT FINDINGS: Patient selection for active surveillance is the first mandatory step required to lower progression...

The European Randomised Study of Screening for Prostate Cancer (ERSPC) showed that Prostate-Specific Antigen (PSA) based screening results in a significant prostate cancer mortality reduction. Although there are concerns on overdiagnosis and overtreatment, it has been shown that the benefits can outweigh the harms if screening is stopped in older ages to prevent overdiagnosis. A limited screening program (for example screening at ages 55-59 years), including active surveillance for men with low-risk tumors, can even be cost-saving, compared with testing in an opportunistic setting in the wrong ages, as currently in Europe...

REVIEW
Qian Li, Xueying Lin, Yuhong Shao, Feixiang Xiang, Anthony E Samir
Ultrasound is the first-line diagnostic tool for diagnosis of thyroid diseases. The low aggressiveness of many thyroid cancers coupled with high sensitivity of sonography can lead to cancer diagnosis and treatment with no effect on outcomes. Ultrasound is recognized as the most important driver of thyroid cancer overdiagnosis. Ultrasound should not be used as a general screening tool and should be reserved for patients at high risk of thyroid cancer and in the diagnostic management of incidentally discovered thyroid nodules...
