3 controlled cohorts of mass-screening for colorectal cancer using a biennial faecal occult blood (HemoccultII®) test on well-defined European populations have demonstrated a 14% to 18% reduction in specific mortality. We aimed to estimate the sensitivity (S) of this HemoccultII®test and and also mean sojourn time (MST) from French colorectal mass-screening programme data. 6 biennial screening rounds were performed from 1988 to 1998 in 45 603 individuals aged 45–74 years in Saône-et-Loire (Burgundy, France). The prevalent/incidence ratio was calculated in order to obtain a direct estimate of the product S.MST. The analysis of the proportional incidence and its modelling was used to derive an indirect estimate of S and MST. The product S.MST was higher for males than females and higher for left colon than either the right colon or rectum. The analysis of the proportional incidence confirmed the result for subsites but no other significant differences were found. The sensitivity was estimated at 0.57 and the MST at 2.56 years. This study confirms that the sensitivity of the Hemoccult test is relatively low and that the relatively short sojourn time is in favour of annual screening. © 2001 Cancer Research Campaign http://www.bjcancer.com

The author reviews the evidence for the efficacy of early detection and mass screening programs in reducing morbidity and mortality from cancer. In cancer of the cervix, although screening reduces morbidity, we still do not have evidence for reduction in mortality. In cancer of the breast, one study suggests a reduction in mortality in the 50-59 year age group following screening by clinical examination and mammography. In other sites, especially lung, there is no evidence at present to support the adoption of mass screening programs. It is important that such programs should be carefully evaluated in the population, preferably in controlled studies.

The aim of this study was to evaluate the volume doubling time (VDT) of lung cancer detected in our annual chest radiograph screening program and to compare it with those previously reported for computed tomography (CT) screening. In total, 209 patients who had a measurable tumor shadow and a history of participating in our chest radiograph mass screening program between 2006 and 2009 were included in this study. Indirect roentgenograms for patients with lung cancer were converted into digital images, and the section showing the tumor was enlarged on the monitor to a size of 0.01 mm. The mean VDT for all the patients was 158 days. Only 3.8% of the patients had a VDT of more than 400 days. In 140 patients with adenocarcinoma, the mean VDT was 177 days, and 5.0% of these patients had a VDT of more than 400 days. In the 44 patients with squamous cell carcinoma, the mean VDT was 133 days, and only 2.3% of these patients had a VDT of more than 400 days. These results were different from those previously reported for CT screening. In several reports on CT screening, more than 20% of the lung cancers had VDTs of more than 400 days. Since it is common knowledge that there are ‘indolent’ lung cancers with a VDT of more than 400 days, screening by annual chest radiography with rare overdiagnosis may need to be reconsidered.

Mass-screening for congenital hypothyroidism has identified cases of mild hypothyroidism, transient hypothyroidism, and transient hyperthyrotropinemia as well as typical hypothyroidism. In this paper, we examine the clinical data of the cases found positive in the screening test at our hospital. From 1989 to 1999 there were 72 patients with positive screening tests who started levothyroxine sodium (l-T4; Thyradin-S) as supplement therapy. At the age of 3 to 4 yr the patients were re-evaluated to determine whether treatment should be continued. Thyroid scintigraphies were done at the same time. We divided these cases into 4 groups. Those in group 1A started l-T4 in early infancy without a TRH test because of obvious clinical evidence of hypothyroidism, and treatment was continued after re-evaluation (n=37). Those in group 1B also started treatment in early infancy without a TRH test, but treatment was discontinued after re-evaluation (n=20). Patients in group 2A started l-T4 after evaluation by a TRH test and treatment was continued after re-evaluation (n=14), while those in group 2B started treatment after a TRH test, but after re-evaluation, treatment was discontinued (n=1). In group 2A, only a low dose of l-T4 was needed, and a slightly elevated TSH and slightly decreased free T4 (FT4) were observed after the drug washout period. However...

Mass screening with abdominal ultrasonography (AUS) has been suggested as a tool to control adult hepatocellular carcinoma (HCC) in individuals, but its efficacy in reducing HCC mortality has never been demonstrated. This study aimed to assess the effectiveness of reducing HCC mortality by mass AUS screening for HCC based on a program designed and implemented in the Changhua Community-based Integrated Screening (CHCIS) program with an efficient invitation scheme guided by the risk score. We invited 11,114 (27.0%) of 41,219 eligible Taiwanese subjects between 45 and 69 years of age who resided in an HCC high-incidence area to attend a risk score-guided mass AUS screening between 2008 and 2010. The efficacy of reducing HCC mortality was estimated. Of the 8,962 AUS screening attendees (with an 80.6% attendance rate), a total of 16 confirmed HCC cases were identified through community-based ultrasonography screening. Among the 16 screen-detected HCC cases, only two died from HCC, indicating a favorable survival. The cumulative mortality due to HCC (per 100,000) was considerably lower in the invited AUS group (17.26) compared with the uninvited AUS group (42.87) and the historical control group (47.51), yielding age- and gender-adjusted relative mortality rates of 0.69 (95% confidence interval [CI]: 0.56-0.84) and 0.63 (95% CI: 0.52-0.77)...

Aims: To assess, using a decision model, the efficiency of ultrasound based and clinical screening strategies for developmental dysplasia of the hip. Methods: The additional cost per additional favourable outcome was compared for the following strategies: clinical screening alone using the Ortolani and Barlow tests; addition of static and dynamic ultrasound examination of the hips of all infants (universal ultrasound) or restricted to infants with defined risk factors (selective ultrasound); "no screening" (that is, clinical diagnosis only). Results: Ultrasound based screening strategies are predicted to be more effective but more costly than clinical screening or no screening. Estimated total costs per 100 000 live births are approximately £4 million for universal ultrasound, £3 million for selective ultrasound, £1 million for clinical screening alone, and £0.4 million for no screening. The relative efficiency of selective ultrasound and clinical screening is poorly differentiated, and depends on how infants are selected for ultrasound as well as the expertise of clinical screening examiners. If training costs less than £20 per child screened, clinical screening alone would be more efficient than selective ultrasound. Relative to no screening...

BACKGROUND: Anal cancer is uncommon and predominantly a disease of the elderly. The human papillomavirus (HPV) has been implicated as a causal agent, and HPV infection is usually transmitted sexually. Individuals who are human immunodeficiency virus (HIV)-positive are particularly vulnerable to HPV infections, and increasing numbers from this population present with anal cancer. OBJECTIVE: To estimate the cost-effectiveness of screening for anal cancer in the high-risk HIV-positive population [in particular, men who have sex with men (MSM), who have been identified as being at greater risk of the disease] by developing a model that incorporates the national screening guidelines criteria. DATA SOURCES: A comprehensive literature search was undertaken in January 2006 (updated in November 2006). The following electronic bibliographic databases were searched: Applied Social Sciences Index and Abstracts (ASSIA), BIOSIS previews (Biological Abstracts), British Nursing Index (BNI), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Database of Systematic Reviews (CDSR), Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, NHS Database of Abstracts of Reviews of Effects (DARE)...

OBJECTIVE: To investigate the association of colorectal cancer (CRC) screening history and subsequent incidence of CRC in New South Wales, Australia. DESIGN, SETTING AND PARTICIPANTS: A total of 196,464 people from NSW recruited to the 45 and Up Study, a large Australian population-based prospective study, by completing a baseline questionnaire distributed from January 2006 to December 2008. Individuals without pre-existing cancer were followed for a mean of 3.78 years (SD, 0.92 years) through linkage to population health datasets. MAIN OUTCOME MEASURES: Incidence of CRC; hazard ratio (HR) according to screening history, adjusted for age, sex, body mass index, income, education, remoteness, family history, aspirin use, smoking, diabetes, alcohol use, physical activity and dietary factors. RESULTS: Overall, 1096 cases of incident CRC accrued (454 proximal colon, 240 distal colon, 349 rectal and 53 unspecified cancers). Ever having undergone CRC screening before baseline was associated with a 44% reduced risk of developing CRC during follow-up (HR, 0.56; 95% CI, 0.49-0.63) compared with never having undergone screening. This effect was more pronounced for those reporting endoscopy (HR, 0.50; 95% CI, 0.43-0.58) than those reporting faecal occult blood testing (FOBT) (HR...

OBJECTIVES: To undertake a structured review and critical appraisal of methods for the model-based cost-utility analysis of screening programmes. Also to develop guidelines and an assessment checklist of good practice in the development of screening models. DATA SOURCES: Major electronic databases of healthcare and operational research literatures were searched up to June 2003. REVIEW METHODS: Searches of the literature were undertaken to identify applied and methodological studies of economic evaluations of healthcare screening programmes. All applied screening models were also reviewed in three broad disease areas (cancer, cardiovascular disease and diabetes), as well as antenatal screening. A second-level review focused on particular aspects of the modelling process through case study assessments of screening models for three specific disease areas (colorectal cancer, abdominal aortic aneurysms and antenatal screening for haemoglobinopathies). A separate literature review of studies reporting the utility effects of screening was also undertaken. Guidelines and an assessment checklist for good practice for screening modelling were developed. RESULTS: Few relevant methodological studies were identified, and no studies reporting direct empirical comparisons of alternative methodologies were retrieved. From the review of disease-based screening models...

Introduction: Cervical and breast cancer are the most common malignancies among women worldwide. Effective screening can facilitate early detection and dramatically reduce mortality rates. The interface between those screening patients and patients most needing screening is complex, and women in remote areas of rural counties face additional barriers that limit the effectiveness of cancer prevention programs. This study compared various methods to improve compliance with mass screening for breast and cervical cancer among women in a remote, rural region of Brazil. Methods: In 2003, a mobile unit was used to perform 10 156 mammograms and Papanicolaou smear tests for women living in the Barretos County region of Sao Paulo state, Brazil (consisting of 19 neighbouring cities). To reach the women, the following community outreach strategies were used: distribution of flyers and pamphlets; media broadcasts (via radio and car loudspeakers); and community healthcare agents (CHCAs) making home visits. Results: The most useful intervention appeared to be the home visits by healthcare agents or CHCAs. These agents of the Family Health Programme of the Brazilian Ministry of Health reached an average of 45.6% of those screened, with radio advertisements reaching a further 11.9%. The great majority of the screened women were illiterate or had elementary level schooling (80.9%) and were of 'poor' or 'very poor' socioeconomic class (67.2%). Conclusions: Use of a mobile screening unit is a useful strategy in developing countries where local health systems have inadequate facilities for cancer screening in underserved populations. A multimodal approach to community outreach strategies...

OBJECTIVES: This study reports on Canadian mammography rates between 1990, when mass screening programs were launched, and 1994/95. METHODS: Mammography rates from 2 national surveys were compared according to the presence of a provincial screening program. RESULTS: Mammography rates among women aged 50 to 69 years (the targeted group) increased significantly, by 16%; increases were twice as high in provinces with screening programs. Among women in their 40s (nontargeted group), the changes were insignificant and independent of screening program status. CONCLUSIONS: Screening programs appear to have influenced the mammography rates of targeted women aged 50 to 69 years.

A survey on mass screening was sent to 1,053 medical geneticists in 18 nations, of whom 677 responded. Three theoretical screening situations were proposed, screening in the workplace for genetic susceptibility to work-related disease, carrier screening for cystic fibrosis, and presymptomatic testing for Huntington disease. Of the respondents, 72 percent thought screening in the workplace should be voluntary, and 81 percent said employers should have no access without the worker's consent, including 22 percent who believed that employers should have no access at all. There was strong consensus in all but one nation that insurance companies should have no access to test results without the worker's consent, and strong consensus in two countries that they should have no access at all. Most (82 percent) believed that screening for cystic fibrosis should be applied to the entire population, but 18 percent believed that it should be applied primarily to Caucasians. In all, 66 percent of respondents believed that individuals at risk for Huntington disease should be told their test results only if they say that they wish to know, recognizing a "right not to know" whether they will develop the disease in later life. Twelve percent thought that spouses should have access to test results if they asked...

Despite encouraging results from recent studies, there is still no consensus to undertake mass screening using the Haemoccult test in the general population. The success of mass screening for colorectal cancer depends among other things on Haemoccult test properties. In on-going screening programmes, the Haemoccult test consists of six slides and a test is considered positive if at least one slide is coloured. The aim of this work was to study the influence of the type and number of positive slides on the Haemoccult test's positive predictive value and characteristics of screened lesions. This work focuses on 63,958 first tests in a mass screening programme in Calvados (France) among people aged 45-74 years. There was a linear relation between the positive predictive value for cancer or an adenoma larger than 1 cm and the number of positive slides (P < 10(-4)). The positive predictive value for cancer or large adenoma was significantly higher when 4-6 slides were positive (44.3%) than when only 1-3 were positive (19.1%) (P < 10(-4)). In this latter group, the subjects in whom tumours were detected were younger and had significantly less extensive cancers. Borderline tests (no slides positive and at least one slide with a blue coloration confined to the edges) had a positive predictive value for cancer or an adenoma larger than 1 cm no different to that of tests with 1-3 positive slides. Subjects with borderline results were markedly younger than the others and had less extensive cancers and rectal localisation more often than the others. Our results suggest that (1) increasing the number of positive slides required to declare a test positive leads to an increase in the positive predictive value but is not to be recommended because of the sensitivity of the test and (2) considering borderline Haemoccult tests as positive in on-going and future mass screening campaigns would allow an increase in the sensitivity of the test...

Prostate cancer plays an important role in widely understood aspects of men's health, and is becoming a growing problem in terms of public life. Prostate cancer is one of the most common neoplasms among men. Male patients can live with prostate cancer for a long time so it is important to offer appropriate males adequate diagnostic tools and treatments. Prostate cancer and PSA potentially represent a “pair” of a disease and an appropriate indicator to be used in mass screening, but regardless of that there is still active debate about it. Extensive use of PSA screening has modified epidemiology of the diseases. Randomized controlled studies provided sufficient results regarding a reduction in mortality through PSA mass screening, while all agreed on risks of overdiagnosis and overtreatment. New and accurate screening tools are necessary, along with adequate counseling and risk stratification.

Objective: to describe mortality from colorectal cancer (CRC) in Andalusia from 1975 to 2001 in order to facilitate decision-making on mass screening. Design: a population-based descriptive study. Considering mortality data from CRC and the resident population of Andalusia during the studied period, the main indicators of mortality by age and sex groups were calculated, and trends were estimated. Results: there have been annual increases in mortality of 1.99% in men and 0.15% in women during the study period. In men, this is mainly due to increased mortality in those older than 65 years, and in women in those in the 35- to 64-year-old age group. In the younger age groups of both sexes, there has been a decline in mortality. The trend of mortality from colon cancer was positive in both men and women, but from rectal cancer was negative in women and slightly positive in men. Conclusions: increased mortality from CRC in Andalusia may justify mass screening measures to potentially change mortality evolution, as has occurred in other countries.

Background and aim: the success of colorectal cancer (CRC) screening programmes largely depends on the quality of the events, processes and outcomes and therefore, quality assurance of endoscopy is an essential component. The quality indicators for colonoscopy in a screening programme setting are different from those performed in symptomatic people. The objective of this study was to report the main quality indicators of colonoscopies performed after a positive faecal occult blood test (FOBT) in a CRC screening programme in Catalonia. Methods: the period of study includes three rounds of the CRC screening programme from June 2006 to July 2013. Two types of FOBT were used: a qualitative biochemical guaiac-based test (gFOBT) and a quantitative immunochemical test (FIT). Quality indicators analysed in this study were compared to recommended colonoscopy standards from the published guidelines. Results: during the study period, 1,806 colonoscopies were performed in 1,691 individuals with a positive FOBT. All indicators were within the standard except waiting time to colonoscopy. Caecal intubation rate was 95.6 % and adequate bowel cleansing 93.6 %. Adenoma detection rate was better using FIT than gFOBT, 30.7 and 3.8 per 1,000 screenees...
