    Background: The European Community recommends mammography, cervical and colorectal cancer screening programmes. In Italy, cancer screening programmes have been included in the Basic Healthcare Parameters (Livelli Essenziali di Assistenza since 2001. Full national coverage of a population-based organized screening programme has been planned for in Italy and is being implemented. Since 2005, the Ministry of Health - Department of Prevention has formally charged The National Centre for Screening Monitoring (Osservatorio Nazionale Screening –ONS- with monitoring and promoting screening programmes nationwide. Participation of target populations is a key indicator of the impact and efficacy of a screening programme in reducing cancer mortality.

    Methods: Attendance of invitees is one of the indicators calculated every year in the quality control of Italian screening programmes. Data collection is organized by means of a structured questionnaire, sent by ONS to the referent for data collection in each Region, who then returns the completed questionnaires to the Regional Centre. Questionnaires are then sent to the National Centre. Logical and epidemiologic checks are performed at both levels. Every year ONS publishes reports on the results of the surveys. A feasibility study for a National data warehouse based on individual records is in progress. The national survey “Multiscopo sulle famiglie” and the Passi Study (Progetti delle Aziende Sanitarie per la Salute in Italia provided additional information regarding spontaneous preventive health care activities in the Italian population.

    Results: Mammography screening: In 2006, 78.2% of Italian women aged 50-69 lived in areas where organised screening was in place (theoretical extension, however, the distribution of the screening activity is not uniform (higher in Northern/Central Italy compared with Southern

    OBJECTIVES: Mammography screening programme sensitivity is evaluated by comparing the interval cancer rate (ICR) with the expected breast cancer incidence without screening, ie. the proportional interval cancer rate (PICR). The PICR is usually found by extrapolating pre-screening incidence rates......, whereas ICR is calculated from data available in the screening programmes. As there is no consensus regarding estimation of background incidence, we seek to validate the ICR measure against the PICR.

    Debate on efficacy, benefits, and risks of breast cancer screening continues to rage, and scientific controversy surrounding overdiagnosis, false positives/false negatives, raises questions about communication to women attending screening programmes. The study compares information provided by invitation letters and leaflets of Italian breast screening programmes in 2001 (N=47) and 2014 (N=80). At both times, nearly all programmes provided adequate practical information and details about screening objectives and test procedures. Information regarding epidemiology/figures was scarce or absent in 2001, while in 2014 a number of programmes began to inform women about screening risks (false negative and positive results and overdiagnosis, 65%, 16%, and 21% respectively) although actual figures were rarely supplied. Despite this small improvement, Italian programmes are still far from giving balanced information. Further efforts should be addressed to providing accurate and transparent information, enabling women to make an informed choice. PMID:26405776

    This field note presents the conclusions and recommendations made at the meeting 'How to reduce social inequalities in cancer screening programmes?' held at the XXVI School of Public Health of Mahon (Menorca, Spain). Participants developed recommendations based on experiences of population-based screening programmes (breast and colorectal) and opportunistic screening (cervical). The conclusions and recommendations focused on four main areas (information systems, evaluation and quality, research, and interventions): the inclusion of social variables at an individual level in health information systems; the establishment of minimum standards for gathering information regarding inequalities in access to preventive services; the performance of actions in vulnerable populations; and the promotion of the exchange of experiences and best practices through the Cancer Screening Programmes Network and working groups of the scientific societies.

    It is demonstrated that screening mammography programmes reduce breast cancer mortality considerably. Nevertheless, radiology techniques have an intrinsic risk being the most important late somatic effect the induction of cancer. This study is made in order to evaluate the risk produced into the population by the Cimadon Valenciana Breast Screening Programme. All the calculations are carried out for two risk models, UNSCEAR 94 and NRPB 93. On the one hand, screening series detriment are investigated as a function of doses delivered and other parameters related to population structure and X-ray equipment. And on the other hand, radiation induced cancer probability for a woman who starts at 45 years and remains into the programme until 65 years old is calculated as a function of mammography unit's doses and average compression breast thickness.

  13. Radial scars detected mammographically in a breast cancer screening programme

    International Nuclear Information System (INIS)

    Radial scars are getting more and more common since implementation of mammography as diagnostic tool in screening women for breast cancer. At Karolinska Hospital, 18987 asymptomatic women, aged 50-69, were screened for breast cancer through mammography during August 1989-May 1991. A total of 735 (3.87%) were recalled for additional views after initial mammograms and 463 (2.44%) were assessed with help of cytology. In all 175 women (0.92%) were selected for surgery and 146 (0.77%) had histologically verified cancers. The remaining 29 (0.15%) had non- malignant lesions of which 11 (0.06%) were radial scars. All radial scars were diagnosed on mammograms and later confirmed with histology. The radiologic characteristics were found to be a) rather thick and long radiating structures accompanied by radiolucent linear structures parallel to some of the spicules, b) absence of calcifications, c) radiolucent areas in the body of the lesion, d) an average mean size of 6 mm and e) changing image in different views. Most of the lesions, 73% (8/11), were in moderately dense breasts and there was no specific relation to the right or left breast. A majority of radial scars, 64% (7/11), were found in the upper outer quadrants, 3/11 in the lower outer quadrants and 1/11 in the lower inner quadrant. Literature shows that histology uses many synonyms for radial scars and therefore team work between radiologists and pathologists is suggested for better conformity of the diagnosis.

    In 2008, the first nationwide skin cancer screening (SCS) programme in the world was established in Germany. The main reason to implement the SCS programme in Germany was the expected reduction of costs of care due to earlier detection of skin cancer. The aim of this commentary is to raise and discuss several unanswered questions related to the German SCS programme. The evidence of a temporary mortality decline of skin melanoma after SCS in Schleswig-Holstein is lower than previously assumed and the temporary decline may have been caused by other factors than screening (e.g. awareness effects, selection bias, data artifact, and random fluctuation). The evaluation of the nationwide effect of SCS on skin cancer mortality is hampered by birth cohort effects and low quality of the routine cause-of-death statistics. The nationwide skin melanoma mortality did not decrease from 2007 through 2014. The time interval between screenings after a screening without pathological findings is unclear. Appropriate research designs are needed that monitor and evaluate the effect of SCS not only on skin cancer mortality but also on other factors that may help to judge the potential benefits and harms of SCS including aggressiveness of therapy, costs of care, quality of life, and stage-specific incidence rates of skin cancer. Furthermore, SCS may profit from a high-risk strategy instead of population-wide screening and from newer technologies for early detection of skin cancer (e.g. dermoscopy). PMID:27371911

    BACKGROUND: In Ireland, colorectal cancer (CRC) is the second most frequently diagnosed cancer in men, after prostate cancer, and the second most frequently diagnosed cancer in women, after breast cancer. By 2020, the number of new cases diagnosed annually in Ireland is projected to have increased by 79% in men and 56% in women. Organised screening for CRC is already underway or is in the process of being rolled out in several European countries, either at a regional or national level. The Adelaide and Meath Hospital\\/ Trinity College Dublin Colorectal Cancer Screening Programme (TTC-CRC-SP) is Ireland\\'s first pilot population based bowel screening programme. METHOD: Based on a biennial test model the pilot aimed to assess the accuracy of FIT and to evaluate the whole programme based on established international key performance indices. RESULTS: To date 9,993 individuals aged 50-74 years have been invited to participate in the TTC-CRC-SP with over 5,000 FIT\\'s analysed. Overall uptake was 51% and FIT positivity was 10%. The programme has undertaken over 400 screening colonoscopies and detected 154 precancerous adenomas and 38 cancerous lesions. CONCLUSIONS: The first round of The Adelaide and Meath Hospital Tallaght\\/Trinity College Dublin Colorectal Cancer Screening Programme has been highly successful and confirmed that there is an advantage for FIT based two stage bowel cancer screening programmes.

    Full Text Available Abstract Background The attendance rate in Estonian cervical cancer screening programme is too low therefore the programme is hardly effective. A cross-sectional population based survey was performed to identify awareness of cervical cancer risk factors, reasons why women do not want to participate in cervical screening programme and wishes for better organisation of the programme. Method An anonymous questionnaire with a covering letter and a prepaid envelope was sent together with the screening invitation to 2942 randomly selected women. Results are based on the analysis of 1054 (36% returned questionnaires. Results Main reasons for non-participation in the national screening programme were a recent visit to a gynaecologist (42.3%, fear to give a Pap-smear (14.3%, long appointment queues (12.9% and unsuitable reception hours (11.8%. Fear to give a Pap-smear was higher among women aged 30 and 35 than 50 and 55 (RR 1.46; 95% CI: 0.82-2.59 and women with one or no deliveries (RR 1.56, 95% CI: 0.94-2.58. In general, awareness of cervical cancer risk factors is poor and it does not depend on socio-demographic factors. Awareness of screening was higher among Estonians than Russians (RR 1.64, 95% CI: 1.46-1.86. Most women prefer to receive information about screening from personally mailed invitation letters (74.8%. Conclusions Women need more information about cervical cancer risk factors and the screening programme. They prefer personally addressed information sharing. Minority groups should be addressed in their own language. A better collaboration with service providers and discouraging smears outside the programme are also required.

    Surrogate measures of screening performance [e.g. interval cancer (IC) proportional incidence] allow timely monitoring of sensitivity and quality. This study explored measures using large (T2+) breast cancers as potential indicators of screening performance. The proportional incidence of T2+ cancers (observed/expected cases) in a population-based screening programme (Trento, 2001-2009) was estimated. A parallel review of 'negative' preceding mammograms for screen-detected T2+ and for all ICs, using 'blinded' independent readings and case-mixes (54 T2+, 50 ICs, 170 controls) was also performed. T2+ cancers were observed in 168 screening participants: 48 at first screen, 67 at repeat screening and 53 ICs. The T2+ estimated proportional incidence was 68% (observed/expected = 168/247), corresponding to an estimated 32% reduction in the rate of T2+ cancers in screening participants relative to that expected without screening. Majority review classified 27.8% (15/54) of T2+ and 28% (14/50) of ICs as screening error (P = 0.84), with variable recall rates amongst radiologists (8.8-15.2%). T2+ review could be integrated as part of quality monitoring and potentially prove more feasible than IC review for some screening services. circle Interval breast cancers, assumed as screening failures, are monitored to estimate screening performance circle Large (T2+) cancers at screening may also represent failed prior screening detection circle Analysis of T2+ lesions may be more feasible than assessing interval cancers circle Analysis of T2+ cancers is a potential further measure of screening performance.

  2. Typetesting of physical characteristics of digital mammography systems for screening within the Flemish breast cancer screening programme

    International Nuclear Information System (INIS)

    To investigate compliance with the acceptance criteria of the European guidelines for quality assurance in breast cancer screening, a typetesting programme of the physical characteristics of digital mammography systems based on direct readout (DR) technology or computed radiography (CR) was organised and executed within the Flemish breast cancer screening programme. While in general image quality/dose characteristics of flat panel DR systems passed the acceptance criteria more easily than CR systems, the slit-scanning direct photon counting system included in present study was outstanding in combining a very low dose with a good image quality. The data obtained up to now indicate the necessity of retuning the AEC for DR systems according to constant contrast to noise ratio (CNR) over the whole range of PMMA thicknesses (20-70 mm) to improve image quality in imaging breasts of large thickness at the cost of higher doses. For the two CR systems which passed the typetesting procedure dose levels do not allow a similar improvement of CNR for thick objects for these systems. The obtained results highlight the importance of the use of high Z target/filter combinations in X-ray generating systems for imaging thick objects to meet the image quality/dose criteria. With respect to image display aspects high-quality 3-megapixel LCD monitors succeeded also in the typetesting procedure in addition to 5-megapixel monitors. However, as zooming and scrolling are necessary for 3-megapixel monitors to get the full resolution capabilities of the image capture system, 5-megapixel monitors are preferred in a busy screening environment.

    Feasibility studies have shown that contrast-enhanced spectral mammography (CESM) increases diagnostic accuracy of mammography. We studied diagnostic accuracy of CESM in patients referred from the breast cancer screening programme, who have a lower disease prevalence than previously published papers on CESM. During 6 months, all women referred to our hospital were eligible for CESM. Two radiologists blinded to the final diagnosis provided BI-RADS classifications for conventional mammography and CESM. Statistical significance of differences between mammography and CESM was calculated using McNemar's test. Receiver operating characteristic (ROC) curves were constructed for both imaging modalities. Of the 116 eligible women, 113 underwent CESM. CESM increased sensitivity to 100.0 % (+3.1 %), specificity to 87.7 % (+45.7 %), PPV to 76.2 % (+36.5 %) and NPV to 100.0 % (+2.9 %) as compared to mammography. Differences between conventional mammography and CESM were statistically significant (p < 0.0001). A similar trend was observed in the ROC curve. For conventional mammography, AUC was 0.779. With CESM, AUC increased to 0.976 (p < 0.0001). In addition, good agreement between tumour diameters measured using CESM, breast MRI and histopathology was observed. CESM increases diagnostic performance of conventional mammography, even in lower prevalence patient populations such as referrals from breast cancer screening. (orig.)

    AIM: This study examined the relevance of using a two sample quantitative immunochemical faecal occult blood test (iFOBT or FIT) at a high cut off stringency by the first population-based colorectal cancer (CRC) pilot screening programme in Ireland. METHOD: Approximately ten thousand individuals between the ages of 50-74 years were invited to perform two consecutive FITs. These were analysed in tandem using the OC-Sensor and participants with at least one positive result with a haemoglobin cut off for positivity at 100 ng\\/ml were offered colonoscopy. RESULTS: A total of 5023 (52%) (2177 (43%) male; 2846 (57%) female) individuals with a median age of 64 years participated. At least one positive FIT test was detected from 514 (10%) individuals. From the 419 (82%) patients who proceeded to colonoscopy 17 (4%) had CRC and 132(33%) had an advanced adenoma. The detection rate for these screen relevant lesions was 3% (95% CIs = 2.5% - 3.5%) and the FIT positive + colonoscopy detection rate was 36% (95% CI = 31% - 40%). The numbers needed to colonoscope to find an advanced lesion was 2.8. The two test system detected four (23.5%) additional patients with CRC and 37 (28%) with an advanced adenoma compared with a single test. CONCLUSION: The CRC miss rate estimated for a single test (23.5%) was unacceptably high when the goal was to maximize the discovery of advanced lesions in the initial screening round. We conclude that the two test protocol at a high cut off threshold is suitable to optimize FIT screening in Ireland. This article is protected by copyright. All rights reserved.

    Cancer screening is a means to detect cancer early with the goal of decreasing morbidity and mortality. At present, there is a reasonable consensus regarding screening for breast, cervical and colorectal cances and the role of screening is under trial in case of cancers of the lung,  ovaries and prostate. On the other hand, good screening tests are not available for some of the commonest cancers in India like the oral, pharyngeal, esophageal and stomach cancers.

    'Nudging--and the underlying idea 'libertarian paternalism'--to an increasing degree influences policy thinking in the healthcare sector. This article discusses the influence exerted upon a woman's choice of participation in the Danish breast screening programme in light of 'libertarian paternalism'. The basic tenet of 'libertarian paternalism' is outlined and the relationship between 'libertarian paternalism' and informed consent investigated. Key elements in the process of enrolling women into the Danish mammography screening programme are introduced. It is shown that for several reasons the influence exerted upon women's choices of participation cannot be justified within a welfare-enhancing libertarian paternalistic framework. The article suggests that screening programmes alternatively adopt a liberty-enhancing approach and considers the practical implications of this alternative. PMID:22766778

    To investigate the impact of digitalisation on performance parameters and breast dose of the Flemish Breast Cancer Screening Programme. Both computed (CR) and direct radiography (DR) are compared with screen-film mammography (SFM). Data from 975,673 mammographic examinations were collected from units which underwent digitalisation from SFM to CR (41 units) or DR (72 units) in the period 2005-2011. Performance indicators were obtained by consulting the Screening Programme database. Phantom and patient dosimetry data were acquired from the physical technical quality assurance of the programme. Digitalisation induced no significant change in cancer detection rate (CDR), percentage of ductal carcinomas in situ and percentage of breast cancers smaller than 1 cm. A decrease in false-positive results and third readings was observed, which was a time-related observation. After digitalisation, positive predictive value (PPV) increased and recall rates decreased. Compared with SFM, an increase of 30 % in mean glandular dose (MGD) was found for CR, while a similar change in the opposite direction was found for DR. No major differences in performance parameters after digitalisation were found. Transition of SFM to CR resulted in a higher MGD and associated lower detection-over-induction ratio (DIR), while the change to DR induced an improvement of DIR. (orig.)

    To investigate the impact of digitalisation on performance parameters and breast dose of the Flemish Breast Cancer Screening Programme. Both computed (CR) and direct radiography (DR) are compared with screen-film mammography (SFM). Data from 975,673 mammographic examinations were collected from units which underwent digitalisation from SFM to CR (41 units) or DR (72 units) in the period 2005-2011. Performance indicators were obtained by consulting the Screening Programme database. Phantom and patient dosimetry data were acquired from the physical technical quality assurance of the programme. Digitalisation induced no significant change in cancer detection rate (CDR), percentage of ductal carcinomas in situ and percentage of breast cancers smaller than 1 cm.

    A population-based organised cervical cancer screening programme (OCCSP) was introduced in Poland in 2006. In this study we have aimed to analyse whether selected parameters related to invasive cervical cancer (ICC) of patients diagnosed in two distant gynaecological oncology centres changed after the first screening round of the programme run between 2006–2008. We have run a retrospective cross-sectional analysis of 189 women diagnosed with ICC between 2002–2005 (directly before introduction of the programme) and 165 patients diagnosed between 2009–2012 (just after the first screening round of the programme) and compared their age at diagnosis, histology, stage of tumours and overall survival (OS). Mean age of patients diagnosed in years 2002–2005 and 2009–2012 was 52.1 and 52.6 years respectively. Squamous cell carcinomas constituted 90.5% and 86.1% of tumours diagnosed in years 2002–2005 and 2009–2012 respectively and the rest of tumours had glandular and other histologies. 74.5% and 61.0% of women diagnosed in years 2002–2005 and 2009–2012 respectively had early ICC (FIGO—International Federation of Gynaecology and Obstetrics stages I-IIA) and the rest had advanced disease (FIGO IIB-IV). We have noticed no significant differences in mean age of patients, histology of tumours and OS of patients with ICC diagnosed before and after the first screening round of OCSSP in Poland. Advanced stages of ICC were more commonly diagnosed after the introduction of OCSSP. Changes only in some clinical parameters of patients with ICC were noticed before and after the first screening round of OCSSP in Poland but OS of patients remained the same. PMID:27196050

  12. Impact of intermediate mammography assessment on the likelihood of false-positive results in breast cancer screening programmes

    International Nuclear Information System (INIS)

    Breast cancer screening is offered to 100% of the target population in Spain and intermediate mammograms (IMs) are sometimes indicated. This study was aimed at analysing the frequency of IMs, the factors determining their recommendation, and their impact on the risk of false-positive results and the detection rate. Data from 3,471,307 mammograms from Spanish breast cancer screening programmes were included. 3.36% of the mammograms were IMs. The factors associated with the use of IMs were age, initial screening, previous invasive tests, a familial history of breast cancer and use of hormone replacement therapy. In screening episodes with an IM, the probability of a false-positive result was 13.74% (95% CI: 13.43-14.05), almost double that in episodes without IMs (6.02%, 95% CI 5.99-6.05). In young women with previous invasive procedures, a familial history of breast cancer or hormone replacement therapy use who were undergoing their initial screen, this probability was lower when IMs were performed. IMs always increased the detection rate. The factors prompting IMs should be characterised so that radiologists can systematise their recommendations according to the presence of the factors maximising the benefits and minimising the adverse effects of this procedure.

    Increasing attendance to screening offers the best potential for improving the effectiveness of well-established cervical cancer screening programs. Self-sampling at home for human papillomavirus (HPV) testing as an alternative to a clinical sampling can be a useful policy to increase attendance. To determine whether self-sampling improves screening attendance for women who do not regularly attend the Norwegian Cervical Cancer Screening Programme (NCCSP), 800 women aged 25-69 years in the Oslo area who were due to receive a 2nd reminder to attend regular screening were randomly selected and invited to be part of the intervention group. Women in this group received one of two self-sampling devices, Evalyn Brush or Delphi Screener. To attend screening, women in the intervention group had the option of using the self-sampling device (self-sampling subgroup) or visiting their physician for a cervical smear. Self-sampled specimens were split and analyzed for the presence of high-risk (hr) HPV by the CLART® HPV2 test and the digene® Hybrid Capture (HC)2 test. The control group consisted of 2593 women who received a 2nd reminder letter according to the current guidelines of the NCCSP. The attendance rates were 33.4% in the intervention group and 23.2% in the control group, with similar attendance rates for both self-sampling devices. Women in the self-sampling subgroup responded favorably to both self-sampling devices and cited not remembering receiving a call for screening as the most dominant reason for previous non-attendance. Thirty-two of 34 (94.1%) hrHPV-positive women in the self-sampling subgroup attended follow-up. In conclusion, self-sampling increased attendance rates and was feasible and well received. This study lends further support to the proposal that self-sampling may be a valuable alternative for increasing cervical cancer screening coverage in Norway. PMID:27073929

The tumour characteristics and PPVs of each group were compared. Radiological patterns (masses, calcifications, distortions and asymmetries) among recalled women were described and PPVs were evaluated. The percentages of ductal carcinoma in situ (DCIS) were higher in DM than in SFM both in the first [18.5% vs. 15.8%(p = 0.580)] and in successive screenings [23.2% vs. 15.7%(p = 0.115)]. PPVs for masses, asymmetries and calcifications were higher in DM, being statistically significant in masses (5.3% vs. 3.9%; proportion ratio: 1.37 95%CI: 1.08-1.72). Among cancers detected by calcifications, the percentage of DCIS was higher in DM (60.3% vs. 46.4%, p = 0.060). PPVs were higher when DM was used, both for further assessments and for invasive procedures, with similar cancer detection rates and no statistically significant differences in tumour characteristics. The greatest improvements in PPVs were found for masses. (orig.)

    Fine-needle aspiration cytology (FNAC) of nonpalpable mammographic lesions has been under attack from two sides for some years. There has been much discussion and controversy as to the ability to differentiate between in situ and invasive carcinomas in cytological material. A further issue is that of optimal sampling to obtain adequate cell material in sufficient quantity. We present the results of FNAC from 832 nonpalpable mammographic abnormalities detected in the course of the breast cancer screening programme in Oslo during 1996-2001. In 11.6% of cases the smears were inadequate, and there were 7% false negatives (FN) and 1.3% false positives. Of the FN, 64% represented microcalcifications and 86% were due to sampling errors. Absolute sensitivity was 74%, complete sensitivity 88% and specificity 88%. In 255 carcinomas a cytological diagnosis of them as in situ or invasive was made. In 93% of the invasive cases (190/205) these had been correctly identified as invasive on FNAC. In 78% of cases proper follow-up could be resolved by cytology/radiology alone. Suboptimal sampling and localization remains the main cause of FN FNAC results. Problems in differentiating between in situ and invasive breast carcinomas can be significantly reduced by applying strict criteria for in situ lesions. PMID:14659146

  19. The Breast Imaging Reporting and Data System (BI-RADS) in the Dutch breast cancer screening programme: its role as an assessment and stratification tool

    International Nuclear Information System (INIS)

    To assess the suitability of the Breast Imaging Reporting and Data System (BI-RADS) as a quality assessment tool in the Dutch breast cancer screening programme. The data of 93,793 screened women in the Amsterdam screening region (November 2005-July 2006) were reviewed. BI-RADS categories, work-up, age, final diagnosis and final TNM classification were available from the screening registry. Interval cancers were obtained through linkage with the cancer registry. BI-RADS was introduced as a pilot in the Amsterdam region before the nationwide introduction of digital mammography (2009-2010). A total of 1,559 women were referred to hospital (referral rate 1.7 %). Breast cancer was diagnosed in 485 women (detection rate 0.52 %); 253 interval cancers were reported, yielding a programme sensitivity of 66 % and specificity of 99 %. BI-RADS 0 had a lower positive predictive value (PPV, 14.1 %) than BI-RADS 4 (39.1 %) and BI-RADS 5 (92.9 %; P < 0.0001). The number of invasive procedures and tumour size also differed significantly between BI-RADS categories (P < 0.0001). The significant differences in PPV, invasive procedures and tumour size match with stratification into BI-RADS categories. It revealed inter-observer variability between screening radiologists and can thus be used as a quality assessment tool in screening and as a stratification tool in diagnostic work-up. (orig.)

    In this position paper, a self-convened team of experts from the Italian Group for Mammography Screening (Gruppo italiano screening mammografico, GISMa) pointed out the problems that increasingly hamper the feasibility and validity of the estimate of the proportional incidence of interval breast cancer (IBC) in Italy, suggested potential solutions and an agenda for research, and proposed that the question of the sensitivity of mammography be viewed in a larger perspective, with a greater attention to radiological review activities and breast radiology quality assurance programmes. The main problems are as follows: the coverage of cancer registration is incomplete; the robustness of using the pre-screening incidence rates as underlying rates decreases with time since the start of screening; the intermediate mammograms performed for early detection purposes may cause an overrepresentation of IBCs; the classification of many borderline screening histories is prone to subjectivity; and, finally, the composition of cohorts of women with negative screening results is uncertain, because several mammography reports are neither clearly negative nor clearly positive, and because of the limitations and instability of the electronic mammography records. Several possibilities can be considered to cope with these issues: standard methods for using the hospital discharge records in the identification of IBCs should be established; for the calculation of regional estimates of the underlying incidence, a suitable mathematical model should be identified; the definition of IBC according to the 2008 GISMa guidelines needs to be updated, especially with respect to in situ cancers and to invasive cancers with borderline screening histories; a closer adherence to standard screening protocols, with a simplified patient management, would make it easier to objectively identify IBCs; alternative methods for estimating the sensitivity of mammography should be taken into consideration; and

    Full Text Available Abstract Background Bowel cancer is common and a major cause of death. The NHS is currently rolling out a national bowel cancer screening programme that aims to cover the entire population by 2010. The programme will be based on the Faecal Occult Blood test (FOBt that reduces mortality from colon cancer by 16%. However, FOB testing has a relatively low positive predictive value, with associated unnecessary cost, risk and anxiety from subsequent investigation, and is unacceptable to a proportion of the target population. Increased levels of an enzyme called matrix metalloproteinase 9 (MMP9 have been found to be associated with colorectal cancer, and this can be measured from a blood sample. MMP9 has potential for detecting those at risk of having colorectal cancer. The aim of this study is to assess whether MMP9 estimation enhances the predictive value of a positive FOBt. Methods and design FOBt positive people aged 60–69 years attending the Wolverhampton NHS Bowel Cancer Screening Unit and providing consent for colonoscopy will be recruited. Participants will provide a blood sample prior to colonoscopy and permission for collection of the clinical outcome from screening unit records. Multivariate logistic regression analyses will determine the independent factors (patient and disease related, MMP9 associated with the prediction of neoplasia. Discussion Colorectal cancer is a major cause of morbidity and mortality. Pilot studies have confirmed the feasibility of the national cancer screening programme that is based on FOBt. However, the test has high false positive rates. MMP9 has significant potential as a marker for both adenomas and cancers. This study is to examine whether using MMP9 as an adjunct to FOBt improves the accuracy of screening and reduces the number of false positive tests that cause anxiety and require invasive and potentially harmful investigation.

  4. Can an alert in primary care electronic medical records increase participation in a population-based screening programme for colorectal cancer? COLO-ALERT, a randomised clinical trial

    International Nuclear Information System (INIS)

    Colorectal cancer is an important public health problem in Spain. Over the last decade, several regions have carried out screening programmes, but population participation rates remain below recommended European goals. Reminders on electronic medical records have been identified as a low-cost and high-reach strategy to increase participation. Further knowledge is needed about their effect in a population-based screening programme. The main aim of this study is to evaluate the effectiveness of an electronic reminder to promote the participation in a population-based colorectal cancer screening programme. Secondary aims are to learn population’s reasons for refusing to take part in the screening programme and to find out the health professionals’ opinion about the official programme implementation and on the new computerised tool. This is a parallel randomised trial with a cross-sectional second stage. Participants: all the invited subjects to participate in the public colorectal cancer screening programme that includes men and women aged between 50–69, allocated to the eleven primary care centres of the study and all their health professionals. The randomisation unit will be the primary care physician. The intervention will consist of activating an electronic reminder, in the patient’s electronic medical record, in order to promote colorectal cancer screening, during a synchronous medical appointment, throughout the year that the intervention takes place. A comparison of the screening rates will then take place, using the faecal occult blood test of the patients from the control and the intervention groups. We will also take a questionnaire to know the opinions of the health professionals. The main outcome is the screening status at the end of the study. Data will be analysed with an intention-to-treat approach. We expect that the introduction of specific reminders in electronic medical records, as a tool to facilitate and encourage direct referral by

    2007-01-01

    Full Text Available Abstract Background Almost one-third of Norwegian women aged 25–69 years invited to have a Pap smear do not attend during the recommended period, and thus constitute a population with high-risk of cervical cancer (CC. Since the incidence of precancerous lesions of the cervix peak with occurrence of pregnancies within the same decade in women aged 25 to 35 years of age, antepartum care presents an opportunity to offer a Pap smear thereby increasing the coverage of the programme. The study objective was to describe the effect of the antepartum Pap smear on the coverage of a cytological CC screening programme. Methods Among 2 175 762 women resident in Norway in 31.12.1996, all women who gave birth in 1996–7 were identified from the Medical Birth Registry of Norway. Attendance to the cervical cancer screening was assessed by linkage to the Cytology Registry separately for the pregnant and non-pregnant women cohorts. The results were stratified by age, history of previous Pap smear and history of invitation to the CC screening programme. Logistic regression was used to estimate the relative probabilities of having a Pap smear adjusted for age, screening history, and time since invitation, for pregnant and non-pregnant women, respectively. Results 69% of the pregnant women had a Pap smear during one year of follow-up since beginning of the pregnancy with the majority taken during the antepartum period. Irrespectively of age or history of having a Pap smear, pregnant women were 4.3 times more likely to have a Pap smear during follow-up compared to non-pregnant women. 63.2% of the pregnant women had a smear as response to the invitation letter compared to 28.7% of the non-pregnant women, OR = 2.1 (95% CI 1.9 to 2.4. As an indication of "over-screening", 5397 pregnant women (57.8% with a smear shortly before the start of follow-up also had a new Papsmear, compared to 83 023 (32.3% in non-pregnant.

  14. Quality assurance programme for screen film mammography

    International Nuclear Information System (INIS)

    The application of radiation in human health, for both the diagnosis and treatment of disease, is an important component of the work of the IAEA. In the area of diagnostic radiology, this work is focused on quality assurance methods to both the promotion of the effective use of radiation for diagnostic outcome, through achieving and maintaining appropriate image quality, and also on dose determination to allow the monitoring and reduction of dose to the patient. In response to heightened awareness of the importance of patient dose contributed by radiology procedures, the IAEA published Dosimetry in Diagnostic Radiology: An International Code of Practice (Technical Reports Series No. 457) in 2007, to form a basis for patient dose determination for the Member States. Further to this, it is recognized that for complex diagnostic procedures, such as mammography, a detailed guidance document is required to give the professionals in the clinical centre the knowledge necessary to assess the patient dose, as well as to ensure that the procedure gives the maximal patient benefit possible. It is well documented that without the implementation of a quality culture and a systematic quality assurance programme with appropriate education, the detection of breast cancer cannot be made at an early enough stage to allow effective curative treatment to be undertaken. Currently there are a number of established quality assurance protocols in mammography from national and regional institutions, however, many of these protocols are distinctive and so a harmonized approach is required. This will allow the Member States to facilitate quality assurance in mammography in a standardized way which will also facilitate the introduction of national quality assurance programmes that are needed to underpin effective population screening programmes for breast cancer. Development of a quality assurance document for screen film mammography was started in 2005 with the appointment of a drafting

    Cervical screening has been one of the most successful public health prevention programmes. For 50 years, cytology formed the basis for screening, and detected cervical intraepithelial lesions (CIN) were treated surgically to prevent progression to cancer. In a high-risk country as Denmark......, screening decreased the incidence of cervical cancer from 34 to 11 per 100,000, age-standardized rate (World Standard Population). Screening is, however, also expensive; Denmark (population: 5.6 million) undertakes close to half a million tests per year, and has 6-8 CIN-treated women for each prevented...... cancer case. The discovery of human papillomavirus (HPV) as the cause of cervical cancer dramatically changed perspectives for disease control.

    Objective. To test the effectiveness of adding a narrative leaflet to the current information material delivered by the NHS English colorectal cancer (CRC) screening programme on reducing socioeconomic inequalities in uptake. Participants. 150,417 adults (59-74 years) routinely invited to complete the guaiac Faecal Occult Blood test (gFOBt) in March 2013. Design. A cluster randomised controlled trial (ISRCTN74121020) to compare uptake between two arms. The control arm received the standard NHS CRC screening information material (SI) and the intervention arm received the standard information plus a supplementary narrative leaflet, which had previously been shown to increase screening intentions (SI + N). Between group comparisons were made for uptake overall and across socioeconomic status (SES). Results. Uptake was 57.7% and did not differ significantly between the two trial arms (SI: 58.5%; SI + N: 56.7%; odds ratio = 0.93; 95% confidence interval: 0.81-1.06; p = 0.27). There was no interaction between group and SES quintile (p = 0.44). Conclusions. Adding a narrative leaflet to existing information materials does not reduce the SES gradient in uptake. Despite the benefits of using a pragmatic trial design, the need to add to, rather than replace, existing information may have limited the true value of an evidence-based intervention on behaviour.

  7. Screening for colorectal cancer.

    He, Jin; Efron, Jonathan E

    2011-01-01

    March is national colorectal cancer awareness month. It is estimated that as many as 60% of colorectal cancer deaths could be prevented if all men and women aged 50 years or older were screened routinely. In 2000, Katie Couric's televised colonoscopy led to a 20% increase in screening colonoscopies across America, a stunning rise called the "Katie Couric Effect". This event demonstrated how celebrity endorsement affects health behavior. Currently, discussion is ongoing about the optimal strategy for CRC screening, particularly the costs of screening colonoscopy. The current CRC screening guidelines are summarized in Table 2. Debates over the optimum CRC screening test continue in the face of evidence that 22 million Americans aged 50 to 75 years are not screened for CRC by any modality and 25,000 of those lives may have been saved if they had been screened for CRC. It is clear that improving screening rates and reducing disparities in underscreened communities and population subgroups could further reduce colorectal cancer morbidity and mortality. National Institutes of Health consensus identified the following priority areas to enhance the use and quality of colorectal cancer screening: Eliminate financial barriers to colorectal cancer screening and appropriate follow-up of positive results of colorectal cancer screening. Develop systems to ensure the high quality of colorectal cancer screening programs. Conduct studies to determine the comparative effectiveness of the various colorectal cancer screening methods in usual practice settings. Encouraging population adherence to screening tests and allowing patients to select the tests they prefer may do more good (as long as they choose something) than whatever procedure is chosen by the medical profession as the preferred test.

    Since the release of the US Preventive Services Task Force and Centers for Medicare and Medicaid Services recommendations for lung cancer screening, low-dose chest computed tomography screening has moved from the research arena to clinical practice. Lung cancer screening programs must reach beyond image acquisition and interpretation and engage in a multidisciplinary effort of clinical shared decision-making, standardization of imaging and nodule management, smoking cessation, and patient follow-up. Standardization of radiologic reports and nodule management will systematize patient care, provide quality assurance, further reduce harm, and contain health care costs. Although the National Lung Screening Trial results and eligibility criteria of a heavy smoking history are the foundation for the standard guidelines for low-dose chest computed tomography screening in the United States, currently only 27% of patients diagnosed with lung cancer would meet US lung cancer screening recommendations. Current and future efforts must be directed to better delineate those patients who would most benefit from screening and to ensure that the benefits of screening reach all socioeconomic strata and racial and ethnic minorities. Further optimization of lung cancer screening program design and patient eligibility will assure that lung cancer screening benefits will outweigh the potential risks to our patients. PMID:27306387

    Lung cancer is the leading cause of cancer deaths worldwide as well as in Korea. A recent National Lung Screening Trial in U.S. revealed that low-dose CT (LDCT) screening reduced lung cancer specific mortality by 20% in high risk individuals as compared to chest radiograph screening. Based on this evidence, several expert societies in U.S. and Korean multisociety collaborative committee developed guidelines for recommendation of lung cancer screening using annual LDCT in high risk populations. In most of the societies high risk groups are defined as persons aged 55 to 74 years, who are current smokers with history of smoking of more than 30 packs per year or ex-smokers, who quit smoking up to 15 or more years ago. The benefits of LDCT screening are modestly higher than the harms in high risk individuals. The harms included a high rate of false-positive findings, over-diagnosis and radiation-related deaths. Invasive diagnostic procedure due to false positive findings may lead to complications. LDCT should be performed in qualified hospitals and interpreted by expert radiologists.

    Full Text Available Colorectal cancer (CRC is the third most common cancer in the world, and mortality has remained the same for the past 50 years, despite advances in diagnosis and treatment. Because significant numbers of patients present with advanced or incurable stages, patients with pre-malignant lesions (adenomatous polyps that occur as result of genetic inheritance or age should be screened, and patients with long-standing inflammatory bowel disease should undergo surveillance. There are different risk groups for CRC, as well as different screening strategies. It remains to be determined which screening protocol is the most cost-effective for each risk catagory. The objective of screening is to reduce morbidity and mortality in a target population. The purpose of this review is to analyze the results of the published CRC screening studies, with regard to the measured reduction of morbidity and mortality, due to CRC in the studied populations, following various screening procedures. The main screening techniques, used in combination or alone, include fecal occult blood tests, flexible sigmoidoscopy, and colonoscopy. Evidence from the published literature on screening methods for specific risk groups is scanty and frequently does not arise from controlled studies. Nevertheless, data from these studies, combined with recent advances in molecular genetics, certainly lead the way to greater efficacy and lower cost of CRC screening.

    Lung cancer is a global health burden and is among the most common and deadliest of all malignancies worldwide. The goal of screening programs is to detect tumors in earlier, curable stages, consequently reducing disease-specific mortality. The issue of screening has great relevance to thoracic surgeons, who should play a leading role in the debate over screening and its consequences. The burden is on thoracic surgeons to work in a multidisciplinary setting to guide and treat these patients safely and responsibly, ensuring low morbidity and mortality of potential diagnostic or therapeutic interventions.

    Full Text Available The aim of this paper is a review of the main procedures for early diagnosis of colorectal cancer, especially for the asymptomatic individuals with high risk to develop this neoplasm, devise the risk groups to develop this cancer and to study the management of these. The advantages and disadvantages or limitations of screening modalities for colorectal cancer, such as faecal occult blood testing with old guaiac-based tests or the new tests for detecting faecal deoxyribonucleic acid of tumor cells, endoscopic screening by flexible sigmoidoscopy, colonoscopy, or CT-colonography and double contrast barium enema examination, are evaluated. The most accurate diagnosed sensibility (95-97% belong to total colonoscopy with biopsy, barium enema having a lower sensibility (83%; the easiest and cheaper screening method represent guaiac-based faecal occult blood tests but with a global predictive positive value of only 5-10%. In our country, as it’s known, most of the colorectal cancer patients presents to the doctor in an advanced local stage or with distant metastases or in other situations like perforation, obstructive or hemorrhaged complications. In all these cases the therapeutic resources are limited and the survival is much diminished. The situation would be different if in the precocious diagnosis in the incipient stage of the colorectal neoplasm, proper treatment resources may assure to these patients a higher life hope. A proper national healthy political program that will promote some fesabile screening programs could diagnose and treat patients with colorectal neoplasm in incipient stages, with the result of prolonged survival and disease-free interval and complete socio-professional reinstatement. These national screening programs may absolve the expensiveness on the patients care with the colorectal neoplasm cancer in the advanced stages that have a poor prognosis.

  9. Screening of newborns for congenital hypothyroidism. Guidance for developing programmes

    International Nuclear Information System (INIS)

    Congenital hypothyroidism is a condition that, if left untreated, can cause lifelong human suffering as a result of severe mental retardation and deficiency of growth. With the involvement of the IAEA, screening programmes to detect congenital hypothyroidism in newborn infants have been introduced successfully in a large number of countries. The cornerstone of these programmes is accurate and reliable screening methods involving isotope techniques and simple medical treatment. The suffering - and heavy social and economic burden - caused by congenital hypothyroidism prompted many countries to institute a formalized screening programme directed at newborns, just as a vaccination programme has become an integral part of child health care. In many other countries however, this type of formalized service has not yet been established. For these countries, the implementation of a neonatal screening programme will bring about a considerable improvement in child health care. It is hoped that the guidance in this publication will be especially useful to the signatories of the United Nations Convention on the Rights of the Child. Several factors that prevail in a country - the climate, political environment, economic development, level of health care and the transportation system - have an influence on the overall operational systems, design and implementation of a screening programme. As such, the design of such a programme will differ greatly from country to country. Nevertheless, neonatal screening programmes have many elements in common. This book draws on the IAEA's experience in this area over more than a decade, and on the results of a regional technical cooperation programme on neonatal screening for congenital hypothyroidism in East Asia (IAEA Project RAS6032). This publication provides guidance aimed specifically at implementing and sustaining programmes for the screening of newborn infants

  11. Screening for breast cancer in England: past and future.

    Science.gov (United States)

    2006-01-01

    The NHS Breast Screening Programme (NHSBSP) began in 1988. It aims to invite all women aged 50-70 years for mammographic screening once every three years. The programme now screens 1.3 million women each year, about 75% of those invited, and diagnoses about 10,000 breast cancers annually. Although some have questioned the value of screening for breast cancer, the scientific evidence demonstrates clearly that regular mammographic screening between the ages of 50 and 70 years reduces mortality from the malignancy. Screened women are slightly more likely than unscreened women to be diagnosed with breast cancer. The cancers in screened women are smaller and are less likely to be treated with mastectomy than they would have been if diagnosed without screening. For every 400 women screened regularly by the NHSBSP over a 10-year period, one woman fewer will die from breast cancer than would have died without screening. The current NHSBSP saves an estimated 1400 lives each year in England. The screening programme spends about pound sterling 3000 for every year of life saved. PMID:16792825

    There remains an extensive debate over lung cancer screening, with lobbying for and against screening for very compelling reasons. The National Lung Screening Trial, International Early Lung Cancer Program, and other major screening studies favor screening with low-dose CT scans and have shown a reduction in lung cancer-specific mortality. The increasing incidence of lung cancer and the dismal survival rate for advanced disease despite improved multimodality therapy have sparked an interest in the implementation of national lung cancer screening. Concerns over imaging workflow, radiation dose, management of small nodules, overdiagnosis bias, lead-time and length-time bias, emerging new technologies, and cost-effectiveness continue to be debated. The authors address each of these issues as they relate to radiologic practice. PMID:26846531

    Aim: To compare the sensitivity of double-contrast barium enema (DCBE) with computed tomography colonography (CTC) to determine whether CTC is superior for the detection of colorectal cancer (CRC) locally, and to compare the results to those of a national barium enema audit. Materials and methods: All patients undergoing diagnostic DCBE or CTC between January 2003 and December 2005 were identified from the picture archiving communication system (PACS). Patients with a confirmed diagnosis of CRC were identified from the local cancer registry. Patients who were not diagnosed as having CRC on imaging were assumed true negatives if they were not listed in the cancer registry by December 2007, giving a minimum of 2 years follow-up. DCBE and CTC reports of all patients with CRC were analysed, and cancer detection was considered to have occurred (positive test result) if the report stated the definite presence of CRC or possible CRC requiring further investigation. Results: 2520 DCBEs and 604 CTCs were included. Twenty-one of 33 patients with CRC were detected using DCBE (incidence 1.31%, sensitivity 63.7%). Thirty-two of 33 patients with CRC were -detected using CTC (incidence 5.46%, sensitivity 97.7%). Conclusion: CTC is more sensitive for the detection of CRC, and its introduction in a district general hospital is justified. However, there has been a consequent decline in DCBE sensitivity, which, if reflected nationally, suggests CTC is the preferential screening test for CRC.

    We explored the dilemma between patients' right not to know their genetic status and the efficient use of health-care resources in the form of clinical cancer screening programmes. Currently, in the Netherlands, 50% risk carriers of heritable cancer syndromes who choose not to know their genetic status have access to the same screening programmes as proven mutation carriers. This implies an inefficient use of health-care resources, because half of this group will not carry the familial mutation. At the moment, only a small number of patients are involved; however, the expanding possibilities for genetic risk profiling means this issue must be addressed because of potentially adverse societal and financial impact. The trade-off between patients' right not to know their genetic status and efficient use of health-care resources was discussed in six focus groups with health-care professionals and patients from three Dutch university hospitals. Professionals prefer patients to undergo a predictive DNA test as a prerequisite for entering cancer screening programmes. Professionals prioritise treating sick patients or proven mutation carriers over screening untested individuals. Participation in cancer screening programmes without prior DNA testing is, however, supported by most professionals, as testing is usually delayed and relatively few patients are involved at present. Reducing the number of 50% risk carriers undergoing screening is expected to be achieved by: offering more psychosocial support, explaining the iatrogenic risks of cancer screening, increasing out-of-pocket costs, and offering a less stringent screening programme for 50% risk carriers.

    The newborn screening programme started in Brazil (1976) through isolated initiatives, without governmental directions and/or policies. According to Health Ministry (2000) data the coverage was 55% and unevenly distributed. Only 17 out of 27 Brazilian states had more than 30% coverage. Public budgets covered only diagnostic examinations. There were no official data about assistance, patient follow-up or detected disorders. The creation of the National Programme (2001) has provided new perspective for newborn screening (NBS) in the public health system. It has provided important official data and established management and care units for each state: Reference Services in Newborn Screening. The programme screened about 13 million newborns from October 2001 to December 2005. The coverage increased to 80.2% (2005) and 74% of the states presented coverage of over 70%. Within 34 accredited Reference Services in 27 Brazilian states, all provide screening for PKU and CH. Ten of them provide screening for haemoglobinopathies as well, and three of them provide also for CF. The Reference Services altogether count on at least 170 health professionals, such as paediatricians, endocrinologists, nutritionists, psychologists and social workers. They are qualified to assist positive cases, within the policies established by the National Programme. There has been significant increase in NBS coverage and follow-up assuredness, including detected cases before the National Programme (10,935 positive cases) mostly in those regions where the programme did not exist. There has been significant evolution in the Newborn Screening as a Public Health Program in Brazil due to the government's commitment (federal and each component state). PMID:17694357

    INTRODUCTION: Hearing screening programmes aim to detect hearing loss in the neonate. The Health Service Executive (HSE) South was the first phase of a national roll-out of a neonatal hearing screening programme in Ireland, going live on 28 April 2011. RESULTS: Over 11,738 babies have been screened for permanent childhood hearing impairment (PCHI) during the first 12 months. The percentage of eligible babies offered hearing screening was 99.2 %. Only 0.2 % (n = 25) of those offered screening declined. 493 (4 %) were referred for immediate diagnostic audiological assessment. The average time between screen and diagnostic audiology appointment was 2 weeks. 15 (1.3\\/1,000) babies have been identified with a PCHI over the 12-month period. 946 (4 %) babies screened were admitted to the neonatal intensive care unit (NICU) for >48 h. The prevalance of PCHI is 7.3\\/1,000 in the NICU population compared to 0.6\\/1000 in the well baby population. 214 (1.8 % of total babies screened) had a clear response in the screening programmes, but were deemed to be at risk of an acquired childhood hearing impairment. These babies will be reassessed with a diagnostic audiology appointment at 8-9 months of age. To date, there is one case of acquired hearing impairment through this targeted follow-up screen. Of the 15 cases of PCHI identified, 8 (53 %) of these had one or more risk factors for hearing loss and 7 (37 %) were admitted to the NICU for >48 h. Four babies were referred for assessment at the National Cochlear Implant Centre.

    2006-08-01

    Full Text Available Introduction: Opportunities for the early detection of disease are not sufficiently being taken advantage of. Specific interventions could increase the uptake of prevention programmes. A comprehensive analysis of effectiveness and cost-effectiveness of these interventions with reference to Germany is still needed. Objectives: This report aimed to describe and assess interventions to increase uptake in primary and secondary prevention and to explore the assessment of their cost-effectiveness. Methods: 29 scientific databases were systematically searched in a wide strategy. Additional references were located from bibliographies. All published systematic reviews and primary studies were assessed for inclusion without language restrictions. Teams of two reviewers identified the literature, extracted data and assessed the quality of the publications independently. Results: Four HTA reports and 22 systematic reviews were identified for the medical evaluation covering a variety of interventions. The economic evaluation was based on two HTA-reports, one meta-analysis and 15 studies. The evidence was consistent for the effectiveness of invitations and reminders aimed at users, and for prompts aimed at health care professionals. These interventions were the most commonly analysed. (Financial Incentives for users and professionals were identified in a small number of studies. Limited evidence was available for cost-effectiveness showing incremental costs for follow-up reminders and invitations by telephone. Evidence for ethical, social and legal aspects pointed to needs in vulnerable populations. Discussion: The material was heterogeneous regarding interventions used, study populations and settings. The majority of references originated from the United States and focused on secondary prevention. Approaching all target groups by invitations and reminders was recommended to increase uptake in prevention programmes in general. Conclusions: Further research

    In 1992 started in the Comunidad Valenciana the Breast Cancer Screening Programme. The programme is oriented to asymptomatic women between 45 and 65 years old, with two mammograms in each breast for the first time that participate and a simple one in later interventions. Between November of 2000 and March of 2001 was extracted a first sample of 100 woman records for all units of the programme. The data extracted in each sample were the kV-voltage, the X-ray tube load and the breast thickness and age of the woman exposed, used directly in dose and detriment calculation. By means of MCNP-4B code and according to the European Protocol for the quality control of the physical and technical aspects of mammography screening, the average total and glandular doses were calculated, and later compared

    The Universal Newborn Hearing Screening (UNHS) programme aims at achieving early detection of hearing impairment. Subsequent diagnosis and intervention should follow promptly. Within the framework of the Ministry of Health project CCM 2013 "Preventing Communication Disorders: a Regional Program for early Identification, Intervention and Care of Hearing Impaired Children", the limitations and strengths of current UNHS programs in Italy have been analysed by a group of professionals working in tertiary centres involved in regional UNHS programmes, using SWOT analysis and a subsequent TOWS matrix. Coverage and lost-to-follow up rates are issues related to UNHS programmes. Recommendations to improve the effectiveness of the UNHS programme have been identified. The need for homogeneous policies, high-quality information and dissemination of knowledge for operators and families of hearing-impaired children emerged from the discussion. PMID:27054385

    Ireland has seen a steady increase in paediatric sickle cell disease (SCD). In 2005, only 25% of children with SCD were referred to the haemoglobinopathy service in their first year. A non-funded screening programme was implemented. This review aimed to assess the impact screening has had. All children referred to the haemoglobinopathy service born in Ireland after 2005 were identified. Data was collected from the medical chart and laboratory system. Information was analysed using Microsoft Excel. 77 children with SCD were identified. The median age at antibiotic commencement in the screened group was 56 days compared with 447 days in the unscreened group, p = < 0.0003. 22 (28%) of infants were born in centre\\'s that do not screen and 17 (81%) were over 6 months old at referral, compared with 14 (21%) in the screened group. 6 (27%) of those in the unscreened group presented in acute crisis compared with 2 (3%) in the screened population. The point prevalence of SCD in Ireland is 0.2% in children under 15 yr of African and Asian descent. We identified delays in referral and treatment, which reflect the lack of government funded support and policy. We suggest all maternity units commence screening for newborns at risk of SCD. It is a cost effective intervention with a number needed to screen of just 4 to prevent a potentially fatal crisis.

    2015-01-01

    Worldwide, lung cancer is the leading cause of mortalitydue to malignancy. The vast majority of cases of lung cancer are smoking related and the most effective way of reducing lung cancer incidence and mortality is by smoking cessation. In the Western world, smoking cessation policies have met with limited success. The other major means of reducing lung cancer deaths is to diagnose cases at an earlier more treatable stage employing screening programmes using chest radiographs or low dose computed tomography. In many countries smoking is still on the increase, and the sheer scale of the problem limits the affordability of such screening programmes. This short review article will evaluate the current evidence and potential areas of research which may benefit policy making across the world.

    Most invasive cervical cancers in industrialized countries are due to the lack of Pap test coverage, very few are due to screening failures. This study aimed at quantifying the proportion of invasive cancers occurring in nonscreened or underscreened women and that in women with a previous negative screening, that is, screening failure, during the first two screening rounds (1996-2002) and in the following rounds (2003-2008) in the Emilia-Romagna region. All cases of invasive cancers registered in the regional cancer registry between 1996 and 2008 were classified according to screening history through a record linkage with the screening programme registry. The incidence significantly decreased from 11.6/100 000 to 8.7/100 000; this decrease is due to a reduction in squamous cell cancers (annual percentage change -6.2; confidence interval: -7.8, -4.6) and advanced cancers (annual percentage change -6.6; confidence interval: -8.8, -4.3), whereas adenocarcinomas and microinvasive cancers were essentially stable. The proportion of cancers among women not yet invited and among nonresponders decreased over the two periods, from 45.5 to 33.3%. In contrast, the proportion of women with a previous negative Pap test less than 5 years and 5 years or more before cancer incidence increased from 5.7 to 13.3% and from 0.3 to 5.5%, respectively. Although nonattendance of the screening programme remains the main barrier to cervical cancer control, the introduction of a more sensitive test, such as the human papillomavirus DNA test, could significantly reduce the burden of disease.

  5. Screening in breast cancer: a view from the front line

    International Nuclear Information System (INIS)

    Mammography screning presents the only real breakthrough in breast cancer in this century. Twenty-five percent of all cancer in women is breast cancer. About 50 percent of these women die from their disease. It has not been possible to reduce breast cancer mortality more than marginally by any mode of treatment. Single view mammography screening can do so, however, at the rate of 30 to 40 percent. Screening has many detractors, especially in the treatment camp. These detractors do not always act in the patients' best interests. Considering the vast resources used up until now in trying to improve on breast cancer treatment, and to little avail, it is time to divert some of these efforts to set up screening programmes wherever possible. Well handled, these are able to reduce suffering and health care costs and save lines

    Full Text Available Abstract Background Breast cancer screening in Denmark is organised by the health services in the five regions. Although general practitioners (GPs are not directly involved in the screening process, they are often the first point of contact to the health care system and thus play an important advisory role. No previous studies, in a health care setting like the Danish system, have investigated the association between GPs’ attitudes towards breast cancer screening and women’s participation in the screening programme. Methods Data on women’s screening participation was obtained from the regional screening authorities. Data on GPs’ attitudes towards breast cancer screening was taken from a previous survey among GPs in the Central Denmark Region. This study included women aged 50-69 years who were registered with a singlehanded GP who had participated in the survey. Results The survey involved 67 singlehanded GPs with a total of 13,288 women on their lists. Five GPs (7% had a negative attitude towards breast cancer screening. Among registered women, 81% participated in the first screening round. Multivariate analyses revealed that women registered with a GP with a negative attitude towards breast cancer screening were 17% (95% CI: 2-34% more likely to be non-participants compared with women registered with a GP with a positive attitude towards breast cancer screening. Conclusion The GPs' attitudes may influence the participation rate even in a system where GPs are not directly involved in the screening process. However, further studies are needed to investigate this association.

There are currently two different methods for preparation of cervical samples: conventional Papanicolaou smear and liquid......-based cytology. MATERIALS AND METHODS: In 2002, the Department of Pathology, Hvidovre Hospital changed over from the conventional Papanicolaou smear screening method to SurePath liquid-based cytology. This article is based on a retrospective comparison on data from the population screening programme for cervical...... cancer in the Municipality of Copenhagen. RESULTS: The number of tests with the diagnosis of "normal cells" decreased 1% after the conversion to liquid-based cytology, whilst the number of tests with "atypical cells" and "cells suspicious for malignancy" increased by 64.3% and 41.2% respectively...

    The International Association for the Study of Lung Cancer (IASLC) Board of Directors convened a computed tomography (CT) Screening Task Force to develop an IASLC position statement, after the National Cancer Institute press statement from the National Lung Screening Trial showed that lung cancer deaths fell by 20%. The Task Force's Position Statement outlined a number of the major opportunities to further improve the CT screening in lung cancer approach, based on experience with cancer screening from other organ sites.The IASLC CT Screening Workshop 2011 further developed these discussions, which are summarized in this report. The recommendation from the workshop, and supported by the IASLC Board of Directors, was to set up the Strategic CT Screening Advisory Committee (IASLC-SSAC). The Strategic CT Screening Advisory Committee is currently engaging professional societies and organizations who are stakeholders in lung cancer CT screening implementation across the globe, to focus on delivering guidelines and recommendations in six specific areas: (i) identification of high-risk individuals for lung cancer CT screening programs; (ii) develop radiological guidelines for use in developing national screening programs; (iii) develop guidelines for the clinical work-up of "indeterminate nodules" resulting from CT screening programmers; (iv) guidelines for pathology reporting of nodules from lung cancer CT screening programs; (v) recommendations for surgical and therapeutic interventions of suspicious nodules identified through lung cancer CT screening programs; and (vi) integration of smoking cessation practices into future national lung cancer CT screening programs.

    2016-09-01

    This study investigates the cancer literacy level in Korean adults and examines whether cancer literacy plays a mediating role in the relationship between population characteristics and cancer screening behaviours. We collected data from 585 community-dwelling adults in Korea using self-administered surveys and face-to-face interviews from October to December in 2009. Guided by Andersen's behavioural model, we used a structural equation model to estimate the effect of cancer literacy as a mediator and found that cancer literacy mediated cancer screening behaviour. In the individual path analysis models, cancer literacy played a significant mediating role for the use of eastern medicine, fatalism, health status and the number of chronic diseases. When controlling for other relevant covariates, we found that in the optimal path model, cancer literacy played a mediating role in the relationship between the use of eastern medicine and self-rated health status as well as cancer screening behaviour. Thus, developing community-based cancer education programmes and training clinical practitioners in eastern medicine clinics about the importance of informing their patients about regular cancer screening may be an option to boost cancer literacy and screening behaviour in Korea.

    Celebrities often promote cancer screening by relating personal anecdotes about their own diagnosis or that of a loved one. We used data obtained from a random-digit dialing survey conducted in the United States from December 2001 through July 2002 to examine the extent to which adults of screening age without a history of cancer had seen or heard or been influenced by celebrity endorsements of screening mammography, prostate-specific antigen (PSA) testing, or sigmoidoscopy or colonoscopy. The survey response rate was 72% among those known to be eligible and 51% among potentially eligible people accounting for those who could not be contacted. A total of 360 women aged 40 years or older and 140 men aged 50 years or older participated in the survey. Most respondents reported they "had seen or heard a celebrity talk about" mammography (73% of women aged 40 years or older), PSA testing (63% of men aged 50 years or older), or sigmoidoscopy or colonoscopy (52% of adults aged 50 years or older). At least one-fourth of respondents who had seen or heard a celebrity endorsement said that the endorsement made them more likely to undergo mammography (25%), PSA testing (31%), or sigmoidoscopy or colonoscopy (37%).

    Lung cancer is the most frequently fatal cancer, with poor survival once the disease is advanced. Annual low dose computed tomography has shown a survival benefit in screening individuals at high risk for lung cancer. Based on the available evidence, the European Society of Radiology and the European Respiratory Society recommend lung cancer screening in comprehensive, quality-assured, longitudinal programmes within a clinical trial or in routine clinical practice at certified multidisciplinary medical centres. Minimum requirements include: standardised operating procedures for low dose image acquisition, computer-assisted nodule evaluation, and positive screening results and their management; inclusion/exclusion criteria; expectation management; and smoking cessation programmes. Further refinements are recommended to increase quality, outcome and cost-effectiveness of lung cancer screening: inclusion of risk models, reduction of effective radiation dose, computer-assisted volumetric measurements and assessment of comorbidities (chronic obstructive pulmonary disease and vascular calcification). All these requirements should be adjusted to the regional infrastructure and healthcare system, in order to exactly define eligibility using a risk model, nodule management and quality assurance plan. The establishment of a central registry, including biobank and image bank, and preferably on a European level, is strongly encouraged. PMID:25929956

  19. Breast cancer screening; cost-effective in practice?

    International Nuclear Information System (INIS)

    The main aim of national breast screening is a reduction in breast cancer mortality. The data on the reduction in breast cancer mortality from three (of the five) Swedish trials in particular gave rise to the expectation that the Dutch programme of 2-yearly screening for women aged 50-70 would produce a 16% reduction in the total population. In all likelihood, many of the years of life gained as a result of screening are enjoyed in good health. According to its critics the actual benefit that can be achieved from the national breast cancer screening programmes is overstated. Considerable benefits have recently been demonstrated in England and Wales. However, the fall was so considerable in such a relatively short space of time that screening (started in 1987) was thought to only have played a small part. As far as the Dutch screening programme is concerned it is still too early to reach any conclusions about a possible reduction in mortality. The first short-term results of the screening are favourable and as good as (or better than) expectations. In Swedish regions where mammographic screening was introduced, a 19% reduction in breast cancer mortality can be estimated at population level, and recently a 20% reduction was presented in the UK. In countries where women are expected to make appointments for screening themselves, the attendance figures are significantly lower and the quality of the process as a whole is sometimes poorer. The benefits of breast cancer screening need to be carefully balanced against the burden to women and to the health care system. Mass breast screening requires many resources and will be a costly service. Cost-effectiveness of a breast cancer screening programme can be estimated using a computer model. Published cost-effectiveness ratios may differ tremendously, but are often the result of different types of calculation, time periods considered, including or excluding downstream cost. The approach of simulation and estimation is here

  4. Two-view versus single-view mammography at subsequent screening in a region of the Dutch breast screening programme

    International Nuclear Information System (INIS)

    We retrospectively determined the effect of analogue two-view mammography versus single-view mammography at subsequent screens on breast cancer detection and determined financial consequences for a current digital mammography setting. Two screening radiologists reviewed the mammograms of 536 screen detected cancers (SDCs) and 171 interval cancers (ICs) with single-view mammography (medio-lateral-oblique view) at the last but one screen (SDCs) or latest screen (ICs). They determined whether two-view mammography at the last (but one) screen could have increased the cancer detection rate at that screening round. For subsequent screens, the radiologists also assessed the percentage of SDCs and ICs that had been missed at previous two-view screening mammography (SDC) or latest two-view screening (IC), respectively. Additional personnel and digital storage costs for standard two-view mammography at subsequent screening were calculated for digital screening. Two-view mammography could have facilitated earlier cancer detection in 40.9% (219/536) of SDCs and 39.8% (68/171) of ICs. For two-view screens, 24.4% of SDCs (213/871) were missed at previous two-view screening and 29.3% of ICs (110/375) were missed at the latest screen. Overall costs increase € 1.03/screen after implementation of digital two-view mammography. Standard two-view mammography at subsequent screening may modestly increase cancer detection at an earlier stage, whereas additional screening costs are limited

  5. Vibrational Microspectroscopy for Cancer Screening

    2015-02-01

    Full Text Available Vibrational spectroscopy analyses vibrations within a molecule and can be used to characterise a molecular structure. Raman spectroscopy is one of the vibrational spectroscopic techniques, in which incident radiation is used to induce vibrations in the molecules of a sample, and the scattered radiation may be used to characterise the sample in a rapid and non-destructive manner. Infrared (IR spectroscopy is a complementary vibrational spectroscopic technique based on the absorption of IR radiation by the sample. Molecules absorb specific frequencies of the incident light which are characteristic of their structure. IR and Raman spectroscopy are sensitive to subtle biochemical changes occurring at the molecular level allowing spectral variations corresponding to disease onset to be detected. Over the past 15 years, there have been numerous reports demonstrating the potential of IR and Raman spectroscopy together with multivariate statistical analysis techniques for the detection of a variety of cancers including, breast, lung, brain, colon, oral, oesophageal, prostate and cervical cancer. This paper discusses the recent advances and the future perspectives in relation to cancer screening applications, focussing on cervical and oral cancer.

    Full Text Available Objectives. To determine whether persons at high risk of lung cancer would participate in lung cancer screening test if available in Australia and to elicit general attitudes towards cancer screening and factors that might affect participation in a screening program. Methods. We developed a 20-item written questionnaire, based on two published telephone interview scripts, addressing attitudes towards cancer screening, perceived risk of lung cancer, and willingness to be screened for lung cancer and to undertake surgery if lung cancer were detected. The questionnaire was given to 102 current and former smokers attending the respiratory clinic and pulmonary rehabilitation programmes. Results. We gained 90 eligible responses (M:F, 69:21. Mean [SD] age was 63 [11] and smoking history was 32 [21] pack years. 95% of subjects would participate in a lung cancer screening test, and 91% of these would consider surgery if lung cancer was detected. 44% of subjects considered that they were at risk of lung cancer. This was lower in ex-smokers than in current smokers. Conclusions. There is high willingness for lung cancer screening and surgical treatment. There is underrecognition of risk among ex-smokers. This misperception could be a barrier to a successful screening or case-finding programme in Australia.

  8. Computer screens and brain cancer

    International Nuclear Information System (INIS)

    Australia, both in the media and at the federal government level, over possible links between screen-based computer use and cancer, brain tumour in particular. The screen emissions assumed to be the sources of the putative hazard are the magnetic fields responsible for horizontal and vertical scanning of the display. Time-varying fluctuations in these magnetic fields induce electrical current flows in exposed tissues. This paper estimates that the induced current densities in the brain of the computer user are up to 1 mA/m2 (due to the vertical flyback). Corresponding values for other electrical appliances or installations are in general much less than this. The epidemiological literature shows no obvious signs of a sudden increase in brain tumour incidence, but the widespread use of computers is a relatively recent phenomenon. The occupational use of other equipment based on cathode ray tubes (such as TV repair) has a much longer history and has been statistically linked to brain tumour in some studies. A number of factors make this an unreliable indicator of the risk from computer screens, however. 42 refs., 3 tabs., 2 figs

    International Nuclear Information System (INIS)

    Aim: To assess whether there are any significant differences in the film-reading histories of interval or screen-detected cancers, and whether this affects stage at diagnosis. Materials and methods: The rates of screen-detected and interval cancers (overall and by radiological categorization) were observed from 268,067 women screened in the East Midlands Breast Screening Programme over 2004–2007 to assess whether there were differences in incidence based on previous film-reading history. Cancers detected at the subsequent screen and film-reading history were analysed to assess whether this affected stage at diagnosis. Analysis undertaken involved cancer detection rates, confidence intervals, and chi-square tests with Monte Carlo simulation. Results: Rates of interval cancers were similar in all groups where at least one reader had indicated recall to assessment (6.1–7.7/1000) and were significantly higher in comparison to women whose previous film-reading outcome was unanimous routine rescreen (2.9/1000; p < 0.001). Four point one percent of interval cancers with no previous recall outcomes were false negatives, which was significantly lower compared to the groups where at least one reader had indicated recall (10.9%; p = 0.005). Cancers detected at the subsequent screen demonstrated no significant difference in prognosis dependent on previous film-reading history (p = 0.503). Conclusion: The prognosis of screen-detected cancers was similar and few cancers were false negatives regardless of film-reading history at the previous screen

    Prior to the introduction of a national cervical screening programme, death rates from cervical cancer in the Republic of Ireland were greater than the death rates in all other regions in Britain and Northern Ireland. The following audit compares the impact of the national cervical screening programme, established on 1 September \\'08, on uptake and results per age group screened before and after its implementation. This retrospective audit was carried out in a four-doctor practice with approximately 1554 GMS and 5000 private patients. Data over a ten month period in \\'08\\/\\'09 was collected from the practice record of cervical smears and compared to the same period in \\'07\\/\\'08. A cohort of 534 Irish urban women was included. A total number of 148 women were screened between October 2007 and July 2008 compared with 386 women screened over the same months in 2008\\/2009. Increase in uptake was most marked in the 25-44 years age group, 100 (\\'07-\\'08) vs. 303 (\\'08-\\'09). The majority of results for both time periods were negative (85% 07\\/08, 81% 08\\/09). There was a higher number of HSIL in \\'08-\\'09 (an increase from 1% to 3.37% of the total screened). This audit clearly supports the introduction of the national cervical screening programme showing both an increase in uptake and a increased pick-up of high grade lesions.

    Several Asian countries are implementing nationwide cancer screening programs. Assessment of the effectiveness of these programs is critical to their success as this is the only way to ensure that the benefits of screening outweigh the harms. In this paper we focus on colorectal cancer (CRC) screening to illustrate the principles of screening program assessment. The International Agency for Research on Cancer (IARC) has defined organized screening, distinguishing it from opportunistic screening. The key advantage of organized screening is that it provides greater protection against the possible harms of screening. Since screening is a process, not simply a test, the effectiveness of a program depends on the quality of each step in the cancer screening process. The evaluation of long-term screening program outcomes (CRC incidence and mortality) will not be observable for many years, given the time it takes to plan, pilot and implement a program. However, early performance indicators of the impact of screening should be monitored to give an early indication whether the program is on track. The European Union (EU) has recommended a minimum dataset to be collected and reported regularly by a screening program. Using information from these data tables, early performance indicators can be generated (e.g., participation rate, proportion of screen-detected cancers that are early-stage). Subsequently, modeling the natural history of the disease can be very helpful to estimate long-term outcomes, making use of these directly measured early performance indicators. Modeling can also be used to estimate the cost-effectiveness of a screening program and the potential impact of changes in policy, as illustrated by its recent use in the Netherlands to change the definition of a positive fecal immunochemical test (FIT) for the CRC screening program. Programs should consider modeling as an important component of screening program evaluation. PMID:26651258

    2007-01-01

    Despite significant improvements in therapy, ovarian cancer continues to be a leading cause of death amongst women with gynaecological malignancies. Advanced stage at diagnosis is thought to be a major contributor to mortality. Hence, there is considerable interest in early detection through screening. In the 1990s, Professor Jacobs pioneered the development of a multimodal ovarian cancer screening (OCS) strategy using serum CA125 as the first line screen and pelvic ultrasound as the second l...

  1. Screening methods of ovarian cancer in adults

    Full Text Available Ovarian cancer is associated with high mortality rate which has improved a little despite therapeutic advances. It causes more deaths than combined cervical and uterine cancer. High mortality is believed to be a direct result of already advanced stage at the time of diagnosis. Survival is excellent in case of early stage disease but poor in late stage disease, regardless of histology. The goal of screening for ovarian cancer is restricted to detection of asymptomatic early stage disease, as precursor lesions of ovarian cancer have not been identified. At present, there is no reliable method of ovarian cancer screening which has been shown to reduce mortality from ovarian cancer. Therefore, routine screening of women in general population can not be currently advised. Screening should be limited to high-risk population and subjects participating in research projects as long as the results of current studies are available.

  2. Continuous quality improvement of colorectal cancer screening

    Quality assurance is a key issue in colorectal cancer screening, because effective screening is able to improve primary prevention of the cancer. The quality measure may be described in terms:how well the screening test tells who truly has a disease (sensitivity) and who truly does not have a disease (specificity). This paper raises concerns about identification of the optimal screening test for colorectal cancer. Colonoscopy vs flexible sigmoidoscopy in colorectal cancer screening has been a source of ongoing debate. A multicentre randomised controlled trial comparing flexible sigmoidoscopy with usual care showed that flexible sigmoidoscopy screening is able to diminish the incidence of distal and proximal colorectal cancer, and also mortality related to the distal colorectal cancer. However, colonoscopy provides a more complete examination and remains the more sensitive exam than flexible sigmoidoscopy. Moreover, colonoscopy with polypectomy significantly reduces colorectal cancer incidence and colorectal cancer-related mortality in the general population. The article considers the relative merits of both methods and stresses an ethical aspect of patient’s involvement in decision-making. Patients should be informed not only about tests tolerability and risk of endoscopy complications, but also that different screening tests for bowel cancer have different strength to exclude colonic cancer and polyps. The authorities calculate effectiveness and costs of the screening tests, but patients may not be interested in statistics regarding flexible sigmoidoscopy screening and from an ethical point of view, they have the right to chose colonoscopy, which is able to exclude a cancer and precancerous lesions in the whole large bowel.

  3. Cancer screening with CT: dose controversy

    International Nuclear Information System (INIS)

    Computed tomographic (CT) cancer screening has seen a steady increase in interest with the introduction of multislice scanners. While the potential benefits of screening are obvious, radiation dose may pose a long-term risk for the screened individual. This article will discuss the basis for radiation risk estimation and give an overview of the current dose controversy surrounding CT screening. Given the current evidence, a non-negligible radiation risk has to be postulated even at very low doses, but estimates depend heavily on the chosen mathematical model. Lung cancer risk is the most important factor in a screening population because it peaks in the time interval between 40 and 70 years of age. Substantial risks for lung cancer development from yearly screening CT examinations are currently discussed in the literature. Risks for colon cancer screening are less because of less frequent screening intervals. For both indications substantial dose reduction up to factors of 5-10 may be possible. Full-body screening remains critical when performed at regular intervals because of the large doses required and the direct exposure of the lungs. If performed in a dose-conscious fashion, individual risks with lung and colon cancer screening are very small, but estimated population risks are non-negligible. (orig.)

    No previous analysis has investigated the determinants of screening uptake for breast and cervical cancer screening for possible spillover effects from one type of screening examination to the other type of screening examination with a dynamic bivariate panel probit model. For our analysis, we used a dynamic random effects bivariate panel probit model with initial conditions (Wooldridge-type estimator) and dependent variables were the participation of breast and cervical cancer screening in the recent year. The balanced panel sample consisted of 844 women from the British Household Panel Survey (BHPS) from the time period 1992 to 2008. Our analysis showed the high relevance of past screening behaviour and the importance of state dependency for the same and the other type of cancer screening examinations even after controlling for covariates and unobserved heterogeneity. The uptake for breast and cervical cancer screening was higher when the same screening examination was done one or three years earlier. This result is in accordance with the medical screening programmes in Great Britain. With regard to breast and cervical cancer screening positive spillover effects existed between screening examinations in the third order lags. Women with a previous visit to a general practitioner and individuals in the recommended age groups had a higher uptake for breast and cervical cancer screening. Other socioeconomic and health related variables had non-uniform results in both screening examinations. Promoting the uptake of one female prevention activity could also enhance the uptake of the other prevention activity. PMID:26487452

    Full Text Available Background: In order to maximize the benefits of HIV care and treatment investments in sub-Saharan Africa, programs can broaden to target other diseases amenable to screening and efficient management. We nested cervical cancer screening into family planning clinics at select sites also receiving PEPFAR support for antiretroviral therapy (ART rollout. This was done using visual inspection with acetic acid (VIA by maternal child health nurses. We report on achievements and obstacles in the first year of the program in rural Mozambique. Methods: VIA was taught to clinic nurses and hospital physicians, with a regular clinical feedback loop for quality evaluation and retraining. Cryotherapy using carbon dioxide as the refrigerant was provided at clinics; loop electrosurgical excision procedure (LEEP and surgery were provided at the provincial hospital for serious cases. No pathology services were available. Results: Nurses screened 4651 women using VIA in Zambézia Province in year one of the program, more than double the Ministry of Health service target. VIA was judged positive for squamous intraepithelial lesions in 8% (n=380 of the women (9% if age ≥30 years (n=3154 and 7% if age <30 years (n=1497; p=0.02. Of the 380 VIA-positive women, 4% (n=16 had lesions (0.3% of 4651 total screened requiring referral to Quelimane Provincial Hospital. Fourteen (88% of these 16 women were seen at the hospital, but records were inadequate to judge outcomes. Of women screened, 2714 (58% either had knowledge of their HIV status prior to VIA or were subsequently sent for HIV testing, of which 583 (21% were HIV positive. Conclusions: Screening and clinical services were successfully provided on a large scale for the first time ever in these rural clinics. However, health manpower shortages, equipment problems, poor paper record systems and a limited ability to follow-up patients inhibited the quality of the cervical cancer screening services.

    International Nuclear Information System (INIS)

    Aim: To investigate whether remodelling of the breast after breast reduction surgery has an effect on mammographic cancer detection. Methods and materials: For women who attended population-based screening between January 1998 to December 2007, data were extracted on their age, history of previous breast reduction, and the result of screening (recall for further assessment, cancer, or no cancer). The number of cancers detected, recalls per 1000 screens and the characteristics of the cancers detected in the two groups was compared. Results: In total 244,147 women with 736,219 screening episodes were reviewed. In the 4743 women who had a breast reduction, 51 breast cancers were detected [age standardized rate (ASR) of 4.28 per 1000 screening episodes; 95% CI 3.11-5.46], compared with 4342 breast cancers in 239 404 women screened in the non-reduction group (ASR of 5.99 per 1000 screening episodes; 95% CI 5.81-6.16). There were fewer cancers in the breast reduction group with a relative risk of 0.71. There was no significant difference in the rate of recall between the two groups, with a crude recall rate of 46.1 per 1000 screening episodes post-breast reduction compared with 50.7 per 1000 screening episodes for women without breast reduction. There was no significant difference in the pathological type or location of the cancer between the two groups of women. Conclusion: Postoperative breast changes following reduction mammoplasty do not significantly hinder analysis of the screening mammogram.

    Most studies comparing full-field digital mammography (FFDM) with conventional screen-film mammography (SFM) have been radiology-based. The pathological implications of FFDM have received little attention in the literature, especially in the context of screening programmes. The primary objective of this retrospective study is to compare FFDM with SFM in a population-based screening programme with regard to a number of pathological parameters.

  9. Lung cancer screening overdiagnosis: reports of overdiagnosis in screening for lung cancer are grossly exaggerated.

    Science.gov (United States)

    Mortani Barbosa, Eduardo J

    2015-08-01

    The National Lung Cancer Screening Trial (NLST) demonstrated a mortality reduction benefit associated with low-dose computed tomography (LDCT) screening for lung cancer. There has been considerable debate regarding the benefits and harms of LDCT lung cancer screening, including the challenges related to its practical implementation. One of the controversies regards overdiagnosis, which conceptually denotes diagnosing a cancer that, either because of its indolent, low-aggressiveness biologic behavior or because of limited life expectancy, is unlikely to result in significant morbidity during the patient's remainder lifetime. In theory, diagnosing and treating these cancers offer no measurable benefit while incurring costs and risks. Therefore, if a screening test detects a substantial number of overdiagnosed cancers, it is less likely to be effective. It has been argued that LDCT screening for lung cancer results in an unacceptably high rate of overdiagnosis. This article aims to defend the opposite stance. Overdiagnosis does exist and to a certain extent is inherent to any cancer-screening test. Nonetheless, the concept is less dualistic and more nuanced than it has been suggested. Furthermore, the average estimates of overdiagnosis in LDCT lung cancer screening based on the totality of published data are likely much lower than the highest published estimates, if a careful definition of a positive screening test reflecting our current understanding of lung cancer biology is utilized. This article presents evidence on why reports of overdiagnosis in lung cancer screening have been exaggerated. PMID:25772581

    Full Text Available Very few studies examined the issue of regret on choosing colorectal cancer (CRC screening tests. We evaluated the determinants of regret and tested the hypothesis that regret over screening choices was associated with poorer screening compliance.A bowel cancer screening centre invited all Hong Kong citizens aged 50-70 years who were asymptomatic of CRC to participate in free-of-charge screening programmes. Upon attendance they attended health seminars on CRC and its screening, and were offered an option to choose yearly faecal immunochemical test (FIT for up to four years vs. one direct colonoscopy. They were not allowed to switch the screening option after decision. A self-administered, four-item validated survey was used to assess whether they regretted over their choice (> 2 = regretful from a scale of 0 [no regret]-5 [extreme regret]. A binary logistic regression model evaluated if initial regret over their choice was associated with poorer programme compliance.From 4,341 screening participants who have chosen FIT or colonoscopy, 120 (2.8% regretted over their decision and 1,029 (23.7% were non-compliant with the screening programme. Younger subjects and people who felt pressure when making their decision were associated with regret. People who regretted their decision were 2.189 (95% C.I. 1.361-3.521, p = 0.001 times more likely to be non-compliant with the programme.This study is the first to show that regret over the initial CRC screening choice was associated with later non-compliance. Screening participants who expressed regret over their choice should receive additional reminders to improve their programmatic compliance.

  14. Population screening for breast cancer in the European Community

    International Nuclear Information System (INIS)

    Although our understanding of the causes of breast cancer is increasing, it is as yet not possible to recommend measures to decrease its occurrence. Therefore we have to resort to a substitute called secondary prevention which aims at preventing the occurrence of metastatic breast cancer and death by detecting the primary cancer in the breast at an earlier point in its natural history. The question whether this can be achieved can only be answered by scientific study. Such studies are being called: population-based screening programmes. Screening requires one or more tests by which one can partition a population in those who probably have a cancer and those who have not. Since an early breast cancer does not produce symptoms like pain the test has to be some sort of objective assessment. In the field of detecting breast cancer we have been greatly helped by the development of a radiologic technique called mammography. Mammography basically is not an easy technique since there is little contrast between structures in the breast compared with e.g. bone. The quality of mammograms, therefore, was not very high in the pioneering era during the nineteen-fifties and -sixties. This presentation discusses a move of a few doctors in New York city: a radiologist, a surgeon and epidemiologist, to design a scientific study which could answer the question whether mammography, added to a standard clinical examination of the breast would decrease mortality from breast cancer

    Colorectal cancer (CRC) screening has been shown to be effective in reducing CRC incidence and mortality. There are currently a number of screening modalities available for implementation into a population-based CRC screening program. Each screening method offers different strengths but also possesses its own limitations as a population-based screening strategy. We review the current evidence base for accepted CRC screening tools and evaluate their merits alongside their challenges in fulfilling their role in the detection of CRC. We also aim to provide an outlook on the demands of a low-risk population-based CRC screening program with a view to providing insight as to which modality would best suit current and future needs.

    Cervical cancer screening programmes in Italy actively invite all 25-64-year-old resident women for the Pap test every 3 years irrespective of their citizenship. Immigrant women come from countries where screening is absent or poorly implemented and the prevalence of human papillomavirus is often high. These women therefore have significant risk factors for cervical cancer. The Italian Group for Cervical Cancer Screening promoted a survey of all the screening programmes on the participation and the positivity and detection rates in Italian and foreign women in 2009-2011. Aggregated data for participation, cytology results, compliance with colposcopy and histology results were collected, distinguishing between women born in Italy and abroad. All comparisons were age adjusted. Forty-eight programmes out of 120 participated in the immigrant survey, with 3 147 428 invited and 1 427 412 screened Italian women and 516 291 invited and 205 948 screened foreign women. Foreign women had a slightly lower participation rate compared with Italians (39.9 vs. 45.4%), whereas compliance with colposcopy was similar (90%). Foreigners showed a higher risk of pathological findings than Italians: cytology positivity [relative risk (RR)=1.25, 95% confidence interval (CI) 1.24-1.27] and detection rate for cervical intraepithelial neoplasia grade 2 (CIN2) (RR=1.39, 95% CI 1.31-1.47), CIN3 (RR=2.07, 95% CI 1.96-2.18) and cancer (RR=2.68, 95% CI 2.24-3.22). The ratio between cancer and CIN was higher in immigrants (0.06 vs. 0.04, P<0.01). Foreign women had a higher risk of cervical precancer and cancer. Because of their high risk and because opportunistic screening does not cover this often disadvantaged group, achieving high participation in screening programmes for foreigners is critical to further reducing the cervical cancer burden in Italy.

    Serum Raman spectroscopy (RS) has previously shown potential in oral cancer diagnosis and recurrence prediction. To evaluate the potential of serum RS in oral cancer screening, premalignant and cancer-specific detection was explored in the present study using 328 subjects belonging to healthy controls, premalignant, disease controls, and oral cancer groups. Spectra were acquired using a Raman microprobe. Spectral findings suggest changes in amino acids, lipids, protein, DNA, and β-carotene across the groups. A patient-wise approach was employed for data analysis using principal component linear discriminant analysis. In the first step, the classification among premalignant, disease control (nonoral cancer), oral cancer, and normal samples was evaluated in binary classification models. Thereafter, two screening-friendly classification approaches were explored to further evaluate the clinical utility of serum RS: a single four-group model and normal versus abnormal followed by determining the type of abnormality model. Results demonstrate the feasibility of premalignant and specific cancer detection. The normal versus abnormal model yields better sensitivity and specificity rates of 64 and 80% these rates are comparable to standard screening approaches. Prospectively, as the current screening procedure of visual inspection is useful mainly for high-risk populations, serum RS may serve as a useful adjunct for early and specific detection of oral precancers and cancer.

  8. Evaluation of the population dose to the UK population from the national health service breast screening programme

    International Nuclear Information System (INIS)

    Full text: In the United Kingdom National Health Service Breast Screening Programme (NHSBSP), women aged between 50 and 70 years are invited for mammography every three years. Originally mammography comprised of a single view of the breast. Subsequently, women attending the programme for the first time have two views taken at their first visit. Since the beginning of 2004, it is NHSBSP's policy for women to have two views at each screening round. After the initial screening stage, some women are invited back for further mammography and possible other investigations. This is referred to as the assessment stage. Breast cancer may be detected at this stage, or women may be referred for a diagnostic surgical biopsy. On an annual basis, the NHSBSP monitors the number of women who attend the breast screening programme, the number of women who are assessed, the number of fine needle aspiration cytology/small core biopsy examinations and the number of cancers detected. This information may be used to deduce the number of screening and assessment examinations women receive. Screening histories for each woman, over four screening rounds, were analysed. Data from five screening programmes was used to select 54,610 women into the study. Women were selected using a standard report on the National Breast Screening Computer Systems held in each screening office, which was included in the study. Cases were selected on the basis of being between the ages of 50 and 53 at the start of the NHSBSP (i.e. between 1989 and 1992). Assessment of the outcome for each screening round for each woman involved assigning a simple Outcome code. Each of the possible pathways through the four screening rounds was analysed. This comprises of 500 possible pathways. These data enabled the following information to be determined. 1) the number of times a woman attended the screening programme. 2) the number of women referred for assessment at each screening round. This information may be used to deduce

This paper compares breast and bowel cancer screening uptake for a cohort of South Asian women invited to undertake both, and similarly investigates these women's breast cancer screening behaviour over a period of fifteen years. Methods Screening data for rounds 1, 2 and 5 (1989-2004 of the NHS breast cancer screening programme and for round 1 of the NHS bowel screening pilot (2000-2002 were obtained for women aged 50-69 resident in the English bowel screening pilot site, Coventry and Warwickshire, who had been invited to undertake breast and bowel cancer screening in the period 2000-2002. Breast and bowel cancer screening uptake levels were calculated and compared using the chi-squared test. Results 72,566 women were invited to breast and bowel cancer screening after exclusions. Of these, 3,539 were South Asian and 69,027 non-Asian; 18,730 had been invited to mammography over the previous fifteen years (rounds 1 to 5. South Asian women were significantly less likely to undertake both breast and bowel cancer screening; 29.9% (n = 1,057 compared to 59.4% (n = 40,969 for non-Asians (p Conclusions Culturally appropriate targeted interventions are required to reduce observed disparities in cancer screening uptakes.

  10. Screening for breast cancer with mammography

    International Nuclear Information System (INIS)

    Mammography is generally accepted as a useful problem-solving clinical tool in characterizing known breast lesions, so that appropriate and timely treatment can be given. However, it remains grossly underutilized at what it does best: screening. The major strengths of mammography are (a) its ability to detect breast cancer at a smaller, potentially more curable stage than any other examination, and (b) its proved efficacy in reducing breast cancer mortality in asymptomatic women aged 40-74. If, as has recently been estimated, screening with mammography and physical examination can be expected to lower breast cancer deaths by 40%-50% among those actually examined (13), then the lives of almost 20,000 U.S. women might be saved each year if screening were to become very widely used. The challenges of the next decade are clear, to mount much more effective campaigns to educate physicians and lay women about the life-saving benefits of breast cancer screening, to devise increasingly effective and lower cost screening strategies, to further improve the current high quality of mammographic imaging despite its increasing proliferation, and to train large numbers of breast imaging specialists to guarantee that the growing case load of screening and problem-solving mammograms is interpreted with a very high level of skill

  11. Breast cancer screening in Canada: a review

    International Nuclear Information System (INIS)

    Organized screening for breast cancer in Canada began in 1988 and has been implemented in all provinces and 2 of the 3 territories. Quality initiatives are promoted through national guidelines which detail best practices in various areas, including achieving quality through a client-service approach, recruitment and capacity, retention, quality of mammography, reporting, communication of results, follow-up and diagnostic workup, and program evaluation; it also offers detailed guidelines for the pathological examination and reporting of breast specimens. The Canadian Breast Cancer Data Base is a national breast cancer screening surveillance system whose objective is to collect information from provincial-screening programs. These data are used to monitor and evaluate the performance of programs and allow comparison with national and international results. A series of standardized performance indicators and targets for the evaluation of performance and quality of organized breast cancer screening programs have been developed from the data base. Although health care is a provincial responsibility in Canada, the collective reporting and comparison of results both nationally and internationally is beneficial in evaluating and refining both screening programs and individual radiologist performance. The results of Canadian performance indicators compare favourably with those of other well-established international screening programs. There are variations in performance indicators across the provinces and territories, but these differences are not extreme. (author)

  12. Who wants cancer screening with PET?

    International Nuclear Information System (INIS)

    Objectives: Cancer screening using whole-body fluorodeoxyglucose-positron emission tomography (FDG-PET) has gradually become popular in Japan. Although some studies have reported high cancer detection rates with PET screening, the justification for such an approach is still unclear, and no evidence has been provided to indicate that PET screening reduces cancer mortality. We measured the general public's willingness to pay (WTP) for this service using a contingent valuation method, after providing them with sufficient information regarding the efficacy and limitations of the service. Methods: A computer-assisted questionnaire survey was conducted on males and females in Japan aged between 40 and 59 years. The study participants (n = 390) were provided with sufficient information about the PET procedure, the high cancer detection rate, false-negatives/false-positives and the fact that the mortality-reducing effect of PET screening has not yet been demonstrated. The participants' WTP was ascertained by a double-bound dichotomous choice approach. Results: The average WTP among all the participants was $68.0 (95% confidence interval: $56.9-79.2). A Weibull regression analysis showed that income, degree of concern about health, and family history of cancer were significant factors affecting WTP. Conclusions: The actual charge for PET screening in Japan is approximately $1000 on average, which is significantly higher than the participants' WTP for the actual benefit obtained from the service. If the Japanese healthcare consumers are well-informed, most of them would avoid purchasing such a costly service.

    2007-07-01

    The purpose of the present study was to evaluate the effectiveness of a new vision-screening programme in detecting ophthalmic disorders in children with developmental delay (DD; IQIQ. A group of 467 children with an IQIQ>80 (85 males, 38 females; age range 3-16y; mean age 10y 5mo [SD 3y 2mo]) had an examination that included new vision-screening items: distance and near visual acuity and stereopsis for near objects (Lang stereo test II). A full ophthalmological examination was also conducted to determine the effectiveness of the new screening items. The previous screening programme consisted of only monocular visual acuity at distance. Sensitivity, specificity, the positive predictive value (PPV), and negative predictive value (NPV) of the tests were calculated with regard to the following ophthalmic disorders: hyperopia, myopia, astigmatism, anistometropia, amblyopia, low vision, and strabismus. Overall, the prevalence of ophthalmic disorders was 33.4% in children with DD and 11.4% in typically developing children. With the use of the new programme, the effectiveness of vision screening in both groups of children was improved. In children with DD, sensitivity increased from 49.4 to 80.1%, specificity decreased from 98.1 to 83.3%, PPV decreased from 92.8 to 70.6%, and NPV increased from 79.4 to 89.3%. In typically developing children, sensitivity improved from 50.0 to 85.7%, specificity declined from 98.2 to 87.2%, PPV decreased from 77.8 to 46.2%, and NPV increased from 93.9 to 97.9%. We conclude that the currently used vision-screening programme can be significantly improved. The speed and simplicity of the proposed screening programme makes it suitable for use by school nurses. The improvements were most prominent in children with DD. PMID:17593122

    BACKGROUND Identification of permanent hearing impairment at the earliest possible age is crucial to maximise the development of speech and language. Universal newborn hearing screening identifies the majority of the 1 in 1000 children born with a hearing impairment, but later onset can occur at any time and there is no optimum time for further screening. A universal but non-standardised school entry screening (SES) programme is in place in many parts of the UK but its value is questioned. OBJECTIVES To evaluate the diagnostic accuracy of hearing screening tests and the cost-effectiveness of the SES programme in the UK. DESIGN Systematic review, case-control diagnostic accuracy study, comparison of routinely collected data for services with and without a SES programme, parental questionnaires, observation of practical implementation and cost-effectiveness modelling. SETTING Second- and third-tier audiology services; community. PARTICIPANTS Children aged 4-6 years and their parents. MAIN OUTCOME MEASURES Diagnostic accuracy of two hearing screening devices, referral rate and source, yield, age at referral and cost per quality-adjusted life-year. RESULTS The review of diagnostic accuracy studies concluded that research to date demonstrates marked variability in the design, methodological quality and results. The pure-tone screen (PTS) (Amplivox, Eynsham, UK) and HearCheck (HC) screener (Siemens, Frimley, UK) devices had high sensitivity (PTS ≥ 89%, HC ≥ 83%) and specificity (PTS ≥ 78%, HC ≥ 83%) for identifying hearing impairment. The rate of referral for hearing problems was 36% lower with SES (Nottingham) relative to no SES (Cambridge) [rate ratio 0.64, 95% confidence interval (CI) 0.59 to 0.69; p < 0.001]. The yield of confirmed cases did not differ between areas with and without SES (rate ratio 0.82, 95% CI 0.63 to 1.06; p = 0.12). The mean age of referral did not differ between areas with and without SES for all referrals but children

    We have studied hair using fibre X-ray diffraction studies with synchrotron radiation and find that hair from breast-cancer patients has a different intermolecular structure to hair from healthy subjects. These changes are seen in all samples of scalp and pubic hair taken from women diagnosed with breast cancer. All the hair samples from women who tested positive for a mutation of the BRCA1 gene, which is associated with a higher risk of breast cancer, also show these changes. Because our results are so consistent, we propose that such hair analyses may be used as a simple, non-invasive screening method for breast cancer.

    Castle, Philip E; Cremer, Miriam

    2013-06-01

    Human papillomavirus (HPV) testing is more reliable and sensitive but less specific than Papanicolaou (Pap) testing/cervical cytology for the detection of cervical precancer and cancer. HPV-negative women are at lower risk of cervical cancer than Pap-negative women. In high-resource settings, HPV testing can be used to make cervical cancer prevention programs more efficient by focusing clinical attention on women who have HPV. In lower-resource settings, where Pap testing has not been sustained or widespread, new, lower-cost HPV tests may make cervical cancer screening feasible. PMID:23732037

  2. Evolving Recommendations on Prostate Cancer Screening.

    2016-01-01

    Results of a number of studies demonstrate that the serum prostate-specific antigen (PSA) in and of itself is an inadequate screening test. Today, one of the most pressing questions in prostate cancer medicine is how can screening be honed to identify those who have life-threatening disease and need aggressive treatment. A number of efforts are underway. One such effort is the assessment of men in the landmark Prostate Cancer Prevention Trial that has led to a prostate cancer risk calculator (PCPTRC), which is available online. PCPTRC version 2.0 predicts the probability of the diagnosis of no cancer, low-grade cancer, or high-grade cancer when variables such as PSA, age, race, family history, and physical findings are input. Modern biomarker development promises to provide tests with fewer false positives and improved ability to find high-grade cancers. Stockholm III (STHLM3) is a prospective, population-based, paired, screen-positive, prostate cancer diagnostic study assessing a combination of plasma protein biomarkers along with age, family history, previous biopsy, and prostate examination for prediction of prostate cancer. Multiparametric MRI incorporates anatomic and functional imaging to better characterize and predict future behavior of tumors within the prostate. After diagnosis of cancer, several genomic tests promise to better distinguish the cancers that need treatment versus those that need observation. Although the new technologies are promising, there is an urgent need for evaluation of these new tests in high-quality, large population-based studies. Until these technologies are proven, most professional organizations have evolved to a recommendation of informed or shared decision making in which there is a discussion between the doctor and patient.

    2016-01-01

    The prevailing questions at this time in both the public mind and the clinical establishment is, do we have sufficient evidence to implement lung cancer Computed Tomography (CT) screening in Europe? If not, what is outstanding? This review addresses the twelve major areas, which are critical to any decision to implement CT screening and where we need to assess whether we have sufficient evidence to proceed to a recommendation for implementation in Europe. The readiness level of these twelve categories in 2015 have been with colour coded, where green indicates we have sufficient evidence, amber is borderline evidence and red requires further evidence. Recruitment from the 'Hard to Reach' community still remains at red, while mortality data, cost effectiveness and screening interval are all categorised as amber. The integration of smoking cessation into CT screening programmes is still considered to be category amber. The US Preventive Services Task Force have recommended that CT screening is implemented in the USA utilising the NLST criteria, apart from continuing screening to 80 years of age. The cost effectiveness of the NLST was calculated to be $81,000/QALY, however, its well recognised that the costs of medical care in the USA, is far higher than that of Europe. Medicare have agreed to cover the cost of screening but have stipulated a number of stringent requirements for inclusion. To date we do not have good CT screening mortality data available in Europe and eagerly await the publication of the NELSON trial data in 2016 and then the pooled UKLS and NELSON data thereafter. However in the meantime we should start planning for implementation in Europe, especially in the areas of the radiological service provision and accreditation, as well as identifying novel mechanisms to recruit from the hardest to reach communities.

    Full Text Available Background: The emergence of validated means to determine which individuals will develop post-traumatic stress disorder (PTSD following a traumatic event has raised the possibility of designing and implementing effective screening programmes following traumatic events. Objective: This study aimed to study the usefulness and implementation of a PTSD screening programme for victims of violent crime presenting to an emergency unit. Design: 3,349 individuals who presented to an emergency unit following a violent crime were asked to complete the Trauma Screening Questionnaire 2 weeks later. Those who scored above a standard cut-off were invited to attend a mental health assessment and subsequently offered treatment according to their needs. Results: Of the 3,349 individuals contacted, 572 (17.1% responded, 338 (10.1% screened positive, 26 (0.78% attended for assessment, and 9 (0.27% received treatment for PTSD. Conclusions: This simple screening programme was not as useful as was hoped raising questions regarding how best to develop screening programmes for PTSD following violent crime and other traumatic events.

    2016-01-01

    Background Attendance in the cervical cancer screening programme is one of the most important factors to lower the risk of contracting the disease. Attendance rates are often low in areas with low socioeconomic status. Charging a fee for screening might possibly decrease attendance in this population. Screening programme coverage is low in low socio-economic status areas in Gothenburg, Sweden, but has increased slightly after multiple interventions in recent years. For many years, women in the region have paid a fee for screening. We studied the effect of abolishing this fee in a trial emanating from the regular cervical cancer screening programme. Method Individually randomised controlled trial. All 3 124 women in three low-resource areas in Gothenburg, due for screening during the study period, were randomised to receive an offer of a free test or the standard invitation stating the regular fee of 100 SEK (≈11 €). The study was conducted during the first six months of 2013. Attendance was defined as a registered Pap smear within 90 days from the date the invitation was sent out. Results Attendance did not differ significantly between women who were charged and those offered free screening (RR 0.93; CI 0.85–1.02). No differences were found within the districts or as an effect of age, attendance after the most recent previous invitation or previous experience of smear taking. Conclusion Abolishment of a modest screening fee in socially disadvantaged urban districts with low coverage, after previous multiple systematic interventions, does not increase attendance in the short term. Other interventions might be more important for increasing attendance in low socio-economic status areas. Trial Registration ClinicalTrials.gov NCT02378324 PMID:26986848

    The decision of whether our patients should undergo prostate cancer screening with the prostate specifc antigen (PSA) test remains daunting. The role of the primary care doctor is to help men decide between a potential decrease in mortality from a slow evolving but sometimes lethal cancer, and the risk of diagnosing and treating cancers that would have otherwise been indolent and asymptomatic. We can structure our discussions with three steps: choice, option, and decision making. A decision aid, such as the one that we have adapted and simplifed from the Collège des médecins du Québec, can help with this complex decision. PMID:26742351

    The Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial randomized men to usual care or annual prostate-specific antigen (PSA) screening for 6 yr and digital rectal examination for 4 yr. This trial found no difference between the intervention and usual care arms of the study in the primary end point of prostate cancer (PCa)-specific mortality. The PLCO trial results have had a major impact on health policy and the rate of PSA screening in the United States. We analyzed the 13-yr screening and outcomes data from the 151 participants who died of PCa in the screening arm of the trial to better understand how randomization to screening failed to prevent PCa death in these men. We found that of these men, 81 (53.6%) either were never screened as part of the trial or had an initial positive screen. Only 17 (11.3%) of those who died reached year 6 of the trial with a PSA <4.0 ng/ml. The men who died in the screening arm were also older at study entry than the average PLCO participant (66 vs 62 yr; p < 0.001). Our analysis should inform the interpretation of the PLCO trial and provide insight into future trial design. PMID:27166670

    Full Text Available Background: Cervical cancer is a largely preventable disease. In western countries, the incidence of and mortality associated with cervical cancer has reduced substantially following the introduction of effective cervical screening programmes. This is in contrast to what is obtained in Africa including Nigeria where cervical screening is rudimentary or non- existent. Aim: This study seeks to assess the knowledge, level of perception and the attitude of female staff and students of Niger Delta University, Nigeria, towards cervical cancer screening. Methods: A questionnaire was used for data collection. The questions were made to capture the objectives of the study.

Pap smear was the most popular screening test mentioned by respondents 100 (41.2%, while some respondents (8.5% of staff and 16.3% of students wrongly believed that blood test is used for cervical cancer screening. There is a significant association between awareness and practice of cervical cancer screening amongst staff and students (X2 = 29.4, P=0.00. Conclusion: The study shows that awareness of cervical cancer screening was higher amongst students than staff of Niger Delta University. Uptake was low in both staff and students. There was an association between awareness and practice of cervical cancer screening amongst respondents. Overall, a greater proportion of the staff respondents had little or no knowledge of cervical cancer screening.

    Full Text Available Abstract Approximately 10% of gastric cancer cases show familial clustering but only 1-3% of gastric carcinomas arise as a result of inherited gastric cancer predisposition syndromes. Direct proof that Hereditary Gastric Cancer a genetic disease with a germline gene defect has come from the demonstration of co-segregation of germline E-cadherin (CDH1 mutations with early onset diffuse gastric cancer in families with an autosomal dominant pattern of inheritance (HDGC. E-cadherin is a transmembrane calcium-dependent cell-adhesion molecule involved in cell-junction formation and the maintenance of epithelial integrity. In this review, we describe frequency and type of CDH1 mutations in sporadic and familial gastric cancer. Further we demonstrate the functional significance of some CDH1 germline missense mutations found in HDGC. We also discuss the CDH1 polymorphisms that have been associated to gastric cancer. We report other types of malignancies associated to HDGC, besides diffuse gastric cancer. Moreover, we review the data available on putative alternative candidate genes screened in familial gastric cancer. Finally, we briefly discuss the role of low-penetrance genes and Helicobacter pylori in gastric cancer. This knowledge is a fundamental step towards accurate genetic counselling, in which a highly specialised pre-symptomatic therapeutic intervention should be offered.

  7. Premarital screening programmes for haemoglobinopathies, HIV and hepatitis viruses: review and factors affecting their success.

    Alswaidi, Fahad M; O'Brien, Sarah J

    2009-01-01

    This literature review is a comprehensive summary of premarital (prenuptial) screening programmes for the most prevalent hereditary haemoglobinopathies, namely thalassaemia and sickle cell disease, and the important infections HIV (human immunodeficiency virus) and hepatitis viruses B and C (HBV and HCV). It describes the background to premarital screening programmes and their value in countries where these diseases are endemic. The use of premarital screening worldwide is critically evaluated, including recent experiences in Saudi Arabia, followed by discussion of the outcomes of such programmes. Despite its many benefits, premarital testing is not acceptable in some communities for various legal and religious reasons, and other educational and cultural factors may prevent some married couples following the advice given by counsellors. The success of these programmes therefore depends on adequate religious support, government policy, education and counselling. In contrast to premarital screening for haemoglobinopathies, premarital screening for HIV and the hepatitis viruses is still highly controversial, both in terms of ethics and cost-effectiveness. In wealthy countries, premarital hepatitis and HIV testing could become mandatory if at-risk, high-prevalence populations are clearly identified and all ethical issues are adequately addressed.

  9. Screening for thyroid cancer in children

    International Nuclear Information System (INIS)

    In the screening of the thyroid diseases in the radiation exposed cohort, it is essential to make correct diagnosis and to measure radiation dose in every subjects in the cohort and to analyze the dose response relationship by the most appropriate statistical method. Thus, thyroid cancer, thyroid adenoma and autoimmune hypothyroidism were confirmed to be radiation-induced thyroid diseases among atomic bomb survivors. A group of investigators from Nagasaki university have been working in the thyroid part of Chernobyl Sasakawa Health and Medical Cooperation Project, and more than 80000 children were screened in 5 diagnostic centers (Mogilev, Gomel, Kiev, Korosten and Klincy). In order to make correct diagnosis, thyroid echo-tomography, measurements of serum levels of free thyroxine, TSH, titers of anti-thyroid antibodies were performed in every children in the cohort and aspiration biopsy was performed when necessary. Whole body Cs137 radioactivity was also determined in every subjects. Children with thyroid cancer confirmed by histology (biopsy or operation) were 2 in Mogilev, 19 in Gomel, 6 in Kiev, 5 in Korosten and 4 in Klincy (until 1994). Since children screened in each center were less than 20000, prevalence of thyroid cancer was remarkably high (lowest 100 and highest 1000/million children) when compared to the other parts of the world (0.2 to 5/million/year). However, there was no dose response relationship between the prevalence of cancer or nodule and whole body Cs137 radioactivity. Although a significant correlation between thyroid cancer and reconstructed thyroid I131 dose was presented, there are no previous reports to prove that I131 produces thyroid cancer in human. Investigation on external radiation and short lived isotopes along with I131 may be important to elucidate the cause of thyroid cancer

  10. Improving colorectal cancer screening: fact and fantasy

    Science.gov (United States)

    Van Dam, Jacques

    2008-02-01

    Premalignant diseases of the gastrointestinal tract, such as Barrett's esophagus, long-standing ulcerative colitis, and adenomatous polyps, have a significantly increased risk for development of adenocarcinoma, most often through an intermediate stage of dysplasia. Adenocarcinoma of the colon is the second most common cancer in the United States. Because patients with colorectal cancer often present with advanced disease, the outcomes are associated with significant morbidity and mortality. Effective methods of early detection are essential. As non-polypoid dysplasia is not visible using conventional endoscopy, surveillance of patients with Barrett's esophagus and ulcerative colitis is performed via a system in which multiple random biopsies are obtained at prescribed intervals. Sampling error and missed diagnoses occur frequently and render current screening methods inadequate. Also, the examination of a tissue biopsy is time consuming and costly, and significant intra- and inter-observer variation may occur. The newer methods discussed herein demonstrate the potential to solve these problems by early detection of disease with high sensitivity and specificity. Conventional endoscopy is based on the observation of white light reflected off the tissue surface. Subtle changes in color and shadow reveal structural changes. New developments in optical imaging go beyond white light, exploiting other properties of light. Several promising methods will be discussed at this meeting and shall be briefly discussed below. However, few such imaging modalities have arrived at our clinical practice. Some much more practical methods to improve colorectal cancer screening are currently being evaluated for their clinical impact. These methods seek to overcome limitations other than those of detecting dysplasia not visible under white light endoscopy. The current standard practice of colorectal cancer screening utilizes colonoscopy, an uncomfortable, sometimes difficult medical

  11. Early diagnosis and screening for colorectal cancer

    International Nuclear Information System (INIS)

    The barium enema has been a neglected tool in the diagnosis of early colon cancer. With appropriate attention to technical detail, the double contrast enema is capable of detecting the smallest malignant and pre-malignant lesions. Many of these early colon cancers are found in asymptomatic patients and these lesions are curable. The goal of a screening program should be to identify by history or by fecal occult blood testing patients at high risk for the development of colon cancer. These patients should be examined by high-quality double contrast enema in the search for these potentially lethal but curable lesions. In addition, we believe that any patient undergoing radiologic examination of the colon for whatever reason, should receive an examination of adequate quality to rule out an early colon cancer.

  12. Studies of benefit and risk resulting from the UK Breast Screening Programme

    International Nuclear Information System (INIS)

    The use of mammography as a screening modality must be justified by comparison of the benefits and risks associated with the technique. The benefit risk ratio (BRR) associated with the National Health Service Breast Screening Programme (NHSBSP) is therefore an important quantity. In order that the BRR can be estimated accurately, it is important that the radiation risks and therefore the Mean Glandular Doses (MGD) received by women attending screening are quantified as precisely as possible. The Monte Carlo model used at present for MGD estimation makes no allowance for alterations in breast composition and is not applicable to women with augmented breasts, leading to significant errors in current MGD estimates. This model has been modified in order to allow for alterations in the proportion of glandular tissue contained within the female breast, and for the presence of a breast prosthesis. The modified models have been coupled with radiographic factors, and information regarding the breast composition of 1258 women, facilitating MGD estimation for these women and for a cohort of 80 women with augmented breasts. This information has in turn been used as a basis for mammography related radiation risk estimation. The associated beneficial effects of screening have been estimated using the results of an established computer simulation. It was found that the use of the conventional Monte Carlo model leads to overestimates of MGD for women with non-augmented breasts of up to 13% over the age range 35-79 years. This error range can be reduced to 1% when compressed breast thickness and age are used to estimate breast glandularity. At low breast thickness, little difference is found between composition dependent MGD-per-film estimates for women with augmented breasts and their non augmented counterparts. At high breast thickness however, the MGD's per film received by women with breast prostheses are considerably lower. In general, the BRR relating to the NHSBSP is

  13. Non-operative diagnosis - effect on repeat-operation rates in the UK breast screening programme

    International Nuclear Information System (INIS)

    Non-operative diagnosis rates in the UK breast screening programme have improved dramatically from 48.8% in 1994/95 (only nine units achieved the then minimum standard of 70%) to 94% in 2005/06 (only seven units failed to achieve the target of 90%). Preoperative and operative history of all 120,550 women diagnosed with screen-detected breast cancer in the UK between April 1994 and March 2006 was derived from different national databases. In 2005/06, 2,790 (17.8%) of the 15,688 women having surgery needed two or more operations. In 2001/02 (non-operative diagnosis rate 87%), the re-operation rate was 23.8% (2,377 of 9,969). Extrapolation backwards to 1994/95 (non-operative diagnosis rate 48.8%) suggests a re-operation rate of 62%. Analysis over the 4 years from April 2002 (n=34,198) demonstrates that 4,089 (12%) women with a correct non-operative diagnosis of invasive disease required additional surgery compared to 1,166 (48%) of women who were under-staged (diagnosed as non-invasive based on core biopsy, but actually suffering from invasive disease). Failure to achieve a non-operative diagnosis of invasive disease (n=1,542) or non-invasive disease (n=2,247) resulted in re-operation rates of 65 and 43% respectively. Given the impact of not having a diagnosis pre-operatively, or of under-staging invasive carcinoma, it seems timely to introduce more sophisticated standards. (orig.)

    The incidence of colorectal cancer has been increasing in many Asian countries including Malaysia during the past few decades. A physician recommendation has been shown to be a major factor that motivates patients to undergo screening. The present study objectives were to describe the practice of colorectal cancer screening by primary care providers in Malaysia and to determine the barriers for not following recommendations. In this cross sectional study involving 132 primary care providers from 44 Primary Care clinics in West Malaysia, self-administered questionnaires which consisted of demographic data, qualification, background on the primary care clinic, practices on colorectal cancer screening and barriers to colorectal cancer screening were distributed. A total of 116 primary care providers responded making a response rate of 87.9%. About 21% recommended faecal occult blood test (FOBT) in more than 50% of their patients who were eligible. The most common barrier was "unavailability of the test". The two most common patient factors are "patient in a hurry" and "poor patient awareness". This study indicates that colorectal cancer preventive activities among primary care providers are still poor in Malaysia. This may be related to the low availability of the test in the primary care setting and poor awareness and understanding of the importance of colorectal cancer screening among patients. More awareness programmes are required for the public. In addition, primary care providers should be kept abreast with the latest recommendations and policy makers need to improve colorectal cancer screening services in health clinics. PMID:24761922

  17. Breast cancer screening: the underuse of mammography

    International Nuclear Information System (INIS)

    The early detection of breast cancer is promoted by the American Cancer Society (ACS) and the American College of Radiology (ACR) by encouraging the regular use of three types of screening: breast self-examination (BSE), the clinical breast examination, and mammography. In August 1983, the ACS publicized seven recommendations pertaining to screening, including a revised statement about the routine use of mammography for women between the ages of 40 and 49 years. In response to the ACS statement, the present study assessed compliance with the updated recommendations for all three types of screening. The results show reasonable rates of compliance for the BSE (53%-69%) and clinical examination (70%-78%). In contrast, only 19% of the women between the ages of 35 and 49 and 25% of the women older than 50 reported complying with the recommendation to undergo one baseline screening mammogram. Some implications for health education by physicians and the professional education of physicians in the use of mammography are discussed

    Full Text Available Despite multiple screening techniques, including colonoscopy, flexible sigmoidoscopy, radiological imaging, and fecal occult blood testing, colorectal cancer remains a leading cause of death. As these techniques improve, their sensitivity to detect malignant lesions is increasing; however, detection of precursor lesions remains problematic and has generated a lack of general acceptance for their widespread usage. Early detection by an accurate, noninvasive, cost-effective, simple-to-use screening technique is central to decreasing the incidence and mortality of this disease. Recent advances in the development of molecular markers in faecal specimens are encouraging for its use as a screening tool. Genetic mutations and epigenetic alterations that result from the carcinogenetic process can be detected by coprocytobiology in the colonocytes exfoliated from the lesion into the fecal matter. These markers have shown promising sensitivity and specificity in the detection of both malignant and premalignant lesions and are gaining popularity as a noninvasive technique that is representative of the entire colon. In this paper, we summarize the genetic and epigenetic fecal molecular markers that have been identified as potential targets in the screening of colorectal cancer.

  19. PACT - IAEA Programme of Action for Cancer Therapy

    International Nuclear Information System (INIS)

    Programme of Action for Cancer Therapy (PACT) is the IAEA's response to the cancer challenge in developing countries. The long-term objective of PACT is Sustainable National Capacity for Cancer Care. The vision of PACT is to (a) build sustainable national cancer care infrastructure and capacity towards eventual self-sufficiency through South-South and North-South partnerships, (b) systematically plan and build capacity to diagnose and treat all patients with radiosensitive cancers, (c) focus on eliminating all cancer morbidity and mortality from unmet treatment needs among patients for whom radiotherapy is most effective and (d) deploy consistent and predictable resources and processes including investments from private donors to meet these objectives over a 5 to 10 year strategy. After the IAEA Board approval in 2004 the PACT office established early 2005. Engaged substantial steps followed to strategize and operationlise PACT. Public awareness campaign was initiated trough the public service announcements, web site development and national outreach seminars. Engagement with WHO, IARC, PAHO, ACS and others followed. The WHA resolution in May 2005 welcomes PACT and asks for a possible joint WHO-IAEA programme. PACT is being operationalised using specific mechanisms such as 'imPACT' (integrated missions of PACT). The 'imPACT' review will assist governments to review, analyse and formulate National Cancer Strategies and Action Plans for capacity building from prevention through palliation. It will also enable institutions to build and develop human resources and plans for capacity in radiation and nuclear oncology. The results of 'imPACT' will enable governments to work with partners, focus on centres of competence/reference to deliver quality cancer care, raise public awareness of cancer prevention, diagnosis and therapy and apply best practices, expand and continue professional development. The expected outcome will be integrated national strategies, action plans

The present study evaluates the opinion among nurses regarding breast cancer screening programs in United Arab Emirates (UAE. Materials and Methods: The study population included 154 nurses practicing at different hospitals in United Arab Emirates (UAE, all nurses who participated in the breast cancer awareness programme organized by Gulf Medical University, Ajman, UAE. A self-administered, pretested, structured, close-ended questionnaire was used for data collection. Statistical Analysis was performed using Predictive Analytic Software (PASW 17. Results: The participants′ age ranged between 20 and 59 years. Fifty percent of the participants strongly agreed with the early detection of breast cancer by performing breast self examination. Thirty-nine percent were of the opinion that women aged 40 years and older should have a mammogram every year and continue to do so and 25.3% strongly felt that women in their 20s and 30s should have clinical breast examination as part of their periodic health examination by health professionals. 33.8% of the respondents strongly agree on providing information on the benefits and limitations of BSE to the female population. Twenty-six percent of the participants strongly agree that women at high risk should get magnetic resonance imaging and mammogram done every year. Conclusion: The present study indicates the need for providing workplace training programs thus equipping them with better knowledge and enhancing their service among the general population.

    2016-05-01

    Multiple advisory groups now recommend that high-risk smokers be screened for lung cancer by low-dose computed tomography. Given that the development of lung cancer screening programs will face many of the same issues that have challenged other cancer screening programs, the National Cancer Institute-funded Population-based Research Optimizing Screening through Personalized Regimens (PROSPR) consortium was used to identify lessons learned from the implementation of breast, cervical, and colorectal cancer screening that should inform the introduction of lung cancer screening. These lessons include the importance of developing systems for identifying and recruiting eligible individuals in primary care, ensuring that screening centers are qualified and performance is monitored, creating clear communication standards for reporting screening results to referring physicians and patients, ensuring follow-up is available for individuals with abnormal test results, avoiding overscreening, remembering primary prevention, and leveraging advances in cancer genetics and immunology. Overall, this experience emphasizes that effective cancer screening is a multistep activity that requires robust strategies to initiate, report, follow up, and track each step as well as a dynamic and ongoing oversight process to revise current screening practices as new evidence regarding screening is created, new screening technologies are developed, new biological markers are identified, and new approaches to health care delivery are disseminated.

    Full Text Available Abstract Background The proven benefit of integrating cervical cancer screening programme into HIV care has led to its adoption as a standard of care. However this is not operational in most HIV clinics in Nigeria. Of the various reasons given for non-implementation, none is backed by scientific evidence. This study was conducted to assess the willingness and acceptability of cervical cancer screening among HIV positive Nigerian women. Methods A cross sectional study of HIV positive women attending a large HIV treatment centre in Lagos, Nigeria. Respondents were identified using stratified sampling method. A pretested questionnaire was used to obtain information by trained research assistants. Obtained information were coded and managed using SPSS for windows version 19. Multivariate logistic regression model was used to determine independent predictor for acceptance of cervical cancer screening. Results Of the 1517 respondents that returned completed questionnaires, 853 (56.2% were aware of cervical cancer. Though previous cervical cancer screening was low at 9.4%, 79.8% (1210 accepted to take the test. Cost of the test (35.2% and religious denial (14.0% were the most common reasons given for refusal to take the test. After controlling for confounding variables in a multivariate logistic regression model, having a tertiary education (OR = 1.4; 95% CI: 1.03-1.84, no living child (OR: 1.5; 95% CI: 1.1-2.0, recent HIV diagnosis (OR: 1.5; 95% CI: 1.1-2.0 and being aware of cervical cancer (OR: 1.5; 95% CI: 1.2-2.0 retained independent association with acceptance to screen for cervical cancer. Conclusions The study shows that HIV positive women in our environment are willing to screen for cervical cancer and that the integration of reproductive health service into existing HIV programmes will strengthen rather than disrupt the services.

    Full Text Available Objective. Vietnamese American women are at the greatest risk for cervical cancer but have the lowest cervical cancer screening rates. This study was to determine whether demographic and acculturation, healthcare access, and knowledge and beliefs are associated with a prior history of cervical cancer screening among Vietnamese women. Methods. Vietnamese women (n=1450 from 30 Vietnamese community-based organizations located in Pennsylvania and New Jersey participated in the study and completed baseline assessments. Logistic regression analyses were performed. Results. Overall levels of knowledge about cervical cancer screening and human papillomavirus (HPV are low. Factors in knowledge, attitude, and beliefs domains were significantly associated with Pap test behavior. In multivariate analyses, physician recommendation for screening and having health insurance were positively associated with prior screening. Conclusion. Understanding the factors that are associated with cervical cancer screening will inform the development of culturally appropriate intervention strategies that would potentially lead to increasing cervical cancer screening rates among Vietnamese women.

  6. Obesity and Cancer Screening according to Race and Gender

    Directory of Open Access Journals (Sweden)

    Heather Bittner Fagan

    2011-01-01

    Full Text Available The relationship between obesity and cancer screening varies by screening test, race, and gender. Most studies on cervical cancer screening found a negative association between increasing weight and screening, and this negative association was most consistent in white women. Recent literature on mammography reports no association with weight. However, some studies show a negative association in white, but not black, women. In contrast, obese/overweight men reported higher rates of prostate-specific antigen (PSA testing. Comparison of prostate cancer screening, mammography, and Pap smears implies a gender difference in the relationship between screening behavior and weight. In colorectal cancer (CRC screening, the relationship between weight and screening in men is inconsistent, while there is a trend towards lower CRC screening in higher weight women.

    Full Text Available Thyroid cancer incidence has increased significantly over the past three decades due, in part, to incidental detection. We examined the association between randomization to screening for lung, prostate, colorectal and/or ovarian cancers and thyroid cancer incidence in two large prospective randomized screening trials.We assessed the association between randomization to low-dose helical CT scan versus chest x-ray for lung cancer screening and risk of thyroid cancer in the National Lung Screening Trial (NLST. In the Prostate Lung Colorectal and Ovarian Cancer Screening Trial (PLCO, we assessed the association between randomization to regular screening for said cancers versus usual medical care and thyroid cancer risk. Over a median 6 and 11 years of follow-up in NLST and PLCO, respectively, we identified 60 incident and 234 incident thyroid cancer cases. Cox proportional hazards regression was used to calculate the cause specific hazard ratios (HR and 95% confidence intervals (CI for thyroid cancer.In NLST, randomization to lung CT scan was associated with a non-significant increase in thyroid cancer risk (HR = 1.61; 95% CI: 0.96-2.71. This association was stronger during the first 3 years of follow-up, during which participants were actively screened (HR = 2.19; 95% CI: 1.07-4.47, but not subsequently (HR = 1.08; 95% CI: 0.49-2.37. In PLCO, randomization to cancer screening compared with usual care was associated with a significant decrease in thyroid cancer risk for men (HR = 0.61; 95% CI: 0.49-0.95 but not women (HR = 0.91; 95% CI: 0.66-1.26. Similar results were observed when restricting to papillary thyroid cancer in both NLST and PLCO.Our study suggests that certain medical encounters, such as those using low-dose helical CT scan for lung cancer screening, may increase the detection of incidental thyroid cancer.

In the Prostate Lung Colorectal and Ovarian Cancer Screening Trial (PLCO), we assessed the association between randomization to regular screening for said cancers versus usual medical care and thyroid cancer risk. Over a median 6 and 11 years of follow-up in NLST and PLCO, respectively, we identified 60 incident and 234 incident thyroid cancer cases. Cox proportional hazards regression was used to calculate the cause specific hazard ratios (HR) and 95% confidence intervals (CI) for thyroid cancer. Results In NLST, randomization to lung CT scan was associated with a non-significant increase in thyroid cancer risk (HR  = 1.61; 95% CI: 0.96–2.71). This association was stronger during the first 3 years of follow-up, during which participants were actively screened (HR  = 2.19; 95% CI: 1.07–4.47), but not subsequently (HR  = 1.08; 95% CI: 0.49–2.37). In PLCO, randomization to cancer screening compared with usual care was associated with a significant decrease in thyroid cancer risk for men (HR  = 0.61; 95% CI: 0.49–0.95) but not women (HR  = 0.91; 95% CI: 0.66–1.26). Similar results were observed when restricting to papillary thyroid cancer in both NLST and PLCO. Conclusion Our study suggests that certain medical encounters, such as those using low-dose helical CT scan for lung cancer screening, may increase the detection of incidental thyroid cancer.

    Full Text Available Abstract Background Cancer screening rates in Korea for five cancer types have increased steadily since 2002. With regard to the life-time cancer screening rates in 2009 according to cancer sites, the second highest was breast cancer (78.1% and the third highest was cervical cancer (76.1%. Despite overall increases in the screening rate, disparities in breast and cervical cancer screening, based on sociodemographic characteristics, still exist. Methods Data from 4,139 women aged 40 to74 years from the 2005 to 2009 Korea National Cancer Screening Survey were used to analyze the relationship between sociodemographic characteristics and receiving mammograms and Pap smears. The main outcome measures were ever having had a mammogram and ever having had a Pap smear. Using these items of information, we classified women into those who had had both types of screening, only one screening type, and neither screening type. We used logistic regression to investigate relationships between screening history and sociodemographic characteristics of the women. Results Being married, having a higher education, a rural residence, and private health insurance were significantly associated with higher rates of breast and cervical cancer screening after adjusting for age and sociodemographic factors. Household income was not significantly associated with mammograms or Pap smears after adjusting for age and sociodemographic factors. Conclusions Disparities in breast and cervical cancer screening associated with low sociodemographic status persist in Korea.

    Colorectal cancer (CRC) is the second most common cancer and second most common cause of cancer-related deaths in Europe. CRC screening has been proven to reduce disease-specific mortality and several European countries employ national screening programmes. These almost exclusively rely on stool tests, with endoscopy used as an adjunct in some countries. Computed tomographic colonography (CTC) is a potential screening test, with an estimated sensitivity of 88 % for advanced neoplasia {>=}10 mm. Recent randomised studies have shown that CTC and colonoscopy have similar yields of advanced neoplasia per screened invitee, indicating that CTC is potentially viable as a primary screening test. However, the evidence is not fully elaborated. It is unclear whether CTC screening is cost-effective and the impact of extracolonic findings, both medical and economic, remains unknown. Furthermore, the effect of CTC screening on CRC-related mortality is unknown, as it is also unknown for colonoscopy. It is plausible that both techniques could lead to decreased mortality, as for sigmoidoscopy and gFOBT. Although radiation exposure is a drawback, this disadvantage may be over-emphasised. In conclusion, the detection characteristics and acceptability of CTC suggest it is a viable screening investigation. Implementation will depend on detection of extracolonic disease and health-economic impact. Key Points circle Meta-analysis of CT colonographic screening showed high sensitivity for advanced neoplasia {>=}10mm. (orig.)

    Debate about the use of prostate-specific antigen (PSA) tests to screen prostate cancer in men is ongoing. Prostate cancer is the most common cancer after skin cancer in men and the second most deadly after lung cancer. An elevated PSA level can lead to this cancer's diagnosis and treatment even before the onset of symptoms. However, other causes also can create a high PSA level, which may lead to men being unnecessarily treated for prostate cancer. This article will shed some light on the issue and discuss prostate cancer screening. PMID:21278045

    Despite the undisputed and impressive success which has been achieved since the 1960s by cervical cytology in the fight against cervical cancer and its precursor stages, during which the mortality rate in industrialized countries over the last 40 years has been reduced by two-thirds to three-quarters, a perfect and error-free screening procedure is still a long way off and will probably never be reached. There are two main reasons for this, the lack of adequate coverage and suboptimal quality and assessment of smears. Two screening procedures are in use Europe, an opportunistic and an organized system. Both systems have many advantages but also disadvantages. In organized programs the coverage is higher (up to 80%), although similar numbers are also achieved by non-organized programs over a 3-year cycle, even if they cannot be so exactly documented. The decision on which system is used depends on the health system of the country, public or non-public, and many other national circumstances. However, in both systems prerequisites for a satisfactory result is a high quality in the sampling technique, the processing and the assessment. Therefore, several guidelines have been introduced by state and medical societies for internal and external quality assurance. New technologies, such as thin-layer cytology or automation for replacement or support of conventional cytology liquid-based cytology proved not to be superior enough to justify the high costs of these systems. The recognition of the strong causal relationship between persistent infection with high-risk human papillomavirus (HPV) types and cervical cancer and its precursors has resulted in the development of comparably simple tests. Primary screening using HPV typing alone is not recommended in opportunistic screening due to the low specificity but high sensitivity because it leads to many clinically irrelevant results which place women under stress. In organized screening HPV testing is always and only possible

    Several research and training initiatives were organized by the International Agency for Research on Cancer (IARC) in collaboration with national institutions in countries such as Angola, Brazil, Burkina Faso, China, Republic of Congo, Guinea, India, Mali, Mauritania, Nepal, Niger, Peru, Tanzania and Thailand among others, to address feasible and effective means of early detection and prevention of cervical, breast and oral cancers. The impact of these activities, that involved over 600 000 participants and more than 1200 healthcare personnel trained on strengthening the local health services in terms of infrastructure, human resources and service delivery aspects in host countries and other regions, is addressed here. These studies, inbuilt in appropriate health services platforms, have resulted in the development and sustenance of several continuing point of care services of screening and treatment in most host countries, particularly in sub-Saharan Africa, and have catalysed regional early detection programmes in India, China and Thailand. The IARC collaborative studies have evolved into major focal points of training and extending services in many countries. The large evidence base, resulting from ours and other studies is likely, in due course, to facilitate much wider scaling up of screening and treatment services through organised programmes.

    Women with mobility disabilities are less likely to access cancer screening, even when they have a primary care provider. The Gateways to Cancer Screening project was initiated to document the challenges for women with disabilities in their access and experiences of screening for breast, cervical and colorectal cancer. The study followed the tenets of participatory action research. Five peer-led focus groups were held with 24 women with mobility disabilities. Study participants identified multiple and interacting institutional barriers to cancer screening. Their discussions highlighted the complex work of (1) arranging and attending health-related appointments, (2) confronting normative assumptions about women's bodies and (3) securing reliable health care and information. These overlapping, mutually reinforcing issues interact to shape how women with disabilities access and experience cancer screening. We explore implications for redesign of cancer screening services and education of health providers, providing specific recommendations suggested by our participants and the findings. PMID:21927868

    Colorectal cancer ranks as one of the most incidental and death malignancies worldwide. Colorectal cancer screening has proven its benefit in terms of incidence and mortality reduction in randomized controlled trials. In fact, it has been recommended by medical organizations either in average-risk or family-risk populations. Success of a screening campaign highly depends on how compliant the target population is. Several factors influence colorectal cancer screening uptake including sociodemographics, provider and healthcare system factors, and psychosocial factors. Awareness of the target population of colorectal cancer and screening is crucial in order to increase screening participation rates. Knowledge about this disease and its prevention has been used across studies as a measurement of public awareness. Some studies found a positive relationship between knowledge about colorectal cancer, risk perception, and attitudes (perceived benefits and barriers against screening) and willingness to participate in a colorectal cancer screening campaign. The mentioned factors are modifiable and therefore susceptible of intervention. In fact, interventional studies focused on average-risk population have tried to increase colorectal cancer screening uptake by improving public knowledge and modifying attitudes. In the present paper, we reviewed the factors impacting adherence to colorectal cancer screening and interventions targeting participants for increasing screening uptake. PMID:24729896

    Full Text Available Background. To determine why women skip rounds and factors influencing return of previous non attenders (PNAs to breast screening. Design and methods. Retrospective, quantitative, structured questionnaire posted to 2500 women. First PNAs did not attend their first screening appointment in 2007/2008 but then attended in 2010; First Controls first attended in 2010 without missed previous appointments. Women who attended screening in 2006 or earlier then skipped a round but returned in 2010 were Subsequent PNAs; Subsequent Controls attended all appointments.Results. More First Controls than First PNAs had family history of cancer (72.7% vs 63.2%; P=0.003; breast cancer (31.3% vs 24.8%; P=0.04. More PNAs lived rurally; more First PNAs had 3rd level education (33.2% vs 23.6%; P=0.002 and fewer had private insurance than First Controls (57.7% vs 64.8%; P=0.04. Excellent/good health was reported in First PNAs and First Controls (82.9% vs 83.2%, but fewer Subsequent PNAs than Subsequent Controls (72.7% vs 84.9%; P=0.000. Common considerations at time of missed appointment were had mammogram elsewhere (33% First PNA and postponed to next round (16% First PNA, 18.8% Subsequent PNA. Considerations when returning to screening were similar for First PNAs and Subsequent PNAs: I am older (35.4%, 29.6%, I made sure I remembered (29%, 23.6%, could reschedule (17.6%, 20.6%, illness of more concern (16.5%, 19%. More First PNAs stated my family/friends advised (22.3% vs 15.2% or my GP (12.6% vs 4.6% advised me to attend, heard good things about BreastCheck (28.8% vs 13.6%.Conclusions. Intermittent attenders do not fit socio-demographic patterns of non-attenders; GP recommendation and word of mouth were important in women’s return to screening. Fear and anxiety seem to act as a screening facilitator rather than an inhibitor.

  6. Changes in equipment and image quality. Impact of one year Austrian breast cancer early detection programme

    International Nuclear Information System (INIS)

    The nationwide Austrian Breast Cancer Early Detection Programme (''BKFP'') started in January 2014. The Austrian Agency for Health and Food Safety Ltd. was entrusted with running the reference center for technical quality control (''RefZQS'') on April 1, 2014. The quality of the radiologists' equipment is evaluated against the standards described in the EUREF-Oeprotocol, which is based on the European guidelines for quality assurance in breast cancer screening and diagnosis (EPQC V4, 2006) and has been optimized for Austrian requirements. In its first year of operation the RefZQS has controlled the entire equipment (mammography, periphery and ultrasound system) of all participating radiologists. A significant number of systems had to be adjusted to meet the EUREF-Oecriteria. Some of the systems could not be adjusted accordingly, and had to be replaced. In the wake of the start of the screening programme, several sites switched from CR to more modern DR systems, yielding a significant benefit by reduction of radiation burden. The most important data after one year of RefZQS, especially according to adjustments and replacements, are presented.

  7. Nipple discharge in a screening programme: Imaging findings with pathological correlation

    International Nuclear Information System (INIS)

    BreastScreen Australia provides free mammographic screening for asymptomatic women over the age of 40, targeting women aged 50–69. Occasionally women will present to screening programmes with a history of nipple discharge, which is uncommonly associated with significant underlying breast disease. Seventy-six women with a history of nipple discharge were recalled to BreastScreen Western Australia assessment centres from 2004 to 2008, of whom 72 were recalled primarily for their symptoms. Thirty-six of these patients had pathology investigations, including 18 nipple discharge smears, 17 fine needle aspirations, 11 core biopsies and eight surgical biopsies or therapeutic resections. The biopsies found 11 intraduct papillomas and one invasive ductal carcinoma with ductal carcinoma in situ. Fourteen patients had imaging findings consistent with benign mammary duct ectasia. Our findings confirm that the presentation of nipple discharge in a screening programme is uncommonly associated with significant breast disease, and present representative cases of the radiological findings with pathological correlation of benign and malignant causes including mammary duct ectasia, intraduct papillomas, multiple papillomas, invasive ductal carcinoma and ductal carcinoma in situ.

    Full Text Available Abstract Background Data comparison between SEER and EUROCARE database provided evidence that colorectal cancer survival in USA is higher than in European countries. Since adjustment for stage at diagnosis markedly reduces the survival differences, a screening bias was hypothesized. Considering the important role of primary care in screening activities, the purpose of the study was to investigate the colorectal cancer screening awareness among Hellenic physicians. Methods 211 primary care physicians were surveyed by mean of a self-reported prescription-habits questionnaire. Both physicians' colorectal cancer screening behaviors and colorectal cancer screening recommendations during usual check-up visits were analyzed. Results Only 50% of physicians were found to recommend screening for colorectal cancer during usual check-up visits, and only 25% prescribed cost-effective procedures. The percentage of physicians recommending stool occult blood test and sigmoidoscopy was 24% and 4% respectively. Only 48% and 23% of physicians recognized a cancer screening value for stool occult blood test and sigmoidoscopy. Colorectal screening recommendations were statistically lower among physicians aged 30 or less (p = 0.012. No differences were found when gender, level and type of specialization were analyzed, even though specialists in general practice showed a trend for better prescription (p = 0.054. Conclusion Contemporary recommendations for colorectal cancer screening are not followed by implementation in primary care setting. Education on presymptomatic control and screening practice monitoring are required if primary care is to make a major impact on colorectal cancer mortality.

  14. Consequences of digital mammography in population-based breast cancer screening: initial changes and long-term impact on referral rates

    International Nuclear Information System (INIS)

    To investigate the referral pattern after the transition to full-field digital mammography (FFDM) in a population-based breast cancer screening programme. Preceding the nationwide digitalisation of the Dutch screening programme, an FFDM feasibility study was conducted. Detection and referral rates for FFDM and screen-film mammography (SFM) were compared for first and subsequent screens. Furthermore, radiological characteristics of referrals in digital screening were assessed. A total of 312,414 screening mammograms were performed (43,913 digital and 268,501 conventional), with 4,473 consecutive referrals (966 following FFDM). Initially the FFDM referral rate peaked, and many false-positive results were noted as a consequence of pseudolesions and increased detection of (benign) microcalcifications. A higher overall referral rate was observed in FFDM screening in both first and subsequent examinations (p <.001), with a significant increase in cancer detection (p =.010). As a result of initial inexperience with digital screening images implementing FFDM in a population-based breast cancer screening programme may lead to a strong, but temporary increase in referral. Dedicated training in digital screening for radiographers and screening radiologists is therefore recommended. Referral rates decrease and stabilise (learning curve effect) at a higher level than in conventional screening, yet with significantly enhanced cancer detection. (orig.)

    Full Text Available The most common incipit of papers published regarding exocrine pancreatic neoplasms is that pancreatic cancer is one of the most lethal cancers, with a rate of incidence equal to that of mortality. Pancreatic cancer is a heterogeneous group of neoplasms in which pancreatic ductal adenocarcinoma is the most common. For the most part, the problems related to the early diagnosis of pancreatic adenocarcinoma are three: 1 to better understand the biology of this tumor; 2 to better investigate the precursors of this tumor; and 3 to plan projects for pancreatic cancer screening in high-risk individuals. Recently, Yachida et al. [1] performed rapid autopsies on seven individuals with Stage IV pancreatic cancer and they found that the clonal populations which give rise to distant metastases are represented within the primary carcinoma, but these clones are genetically evolved from the original parental, non-metastatic clone. Thus, the genetic heterogeneity of the metastases reflects that of the primary carcinoma. Most important, when the authors performed a quantitative analysis of the timing of the genetic evolution of pancreatic cancer, they found that there was at least a decade between the occurrence of the initial mutation and the birth of the parental, non-metastatic founder cell. At least five more years are required for the acquisition of metastatic ability and patients die an average two years thereafter. As underscored by the authors, these data have an important implication in planning population screening for the purpose of preventing pancreatic cancer deaths: in fact, quantitative analysis indicated a large window, of at least a decade, in which the disease could be diagnosed while it is still in the curative stage. This model also predicts an average of 6.8 years between the birth of the cell giving rise to the parental clone and the seeding of the index metastasis.

It will be important to continue to investigate factors associated with up-to-date CRC screening by each modality.

  17. Epidemiology, aetiology, diagnosis and screening of lung cancer

    International Nuclear Information System (INIS)

    Lung cancer is the leading cause of cancer death globally. Smoking causes about 90 % of all lung cancer cases. Passive, i.e. involuntary smoking has been confirmed to enhance the risk of lung cancer in exposed people. Individual susceptibility is one of important factors in lung cancer formation. New knowledge in epidemiology and aetiology of lung cancer gives new possibilities in diagnostic and screening of this disease. Results of large randomised trials aimed at new technologies in lung cancer screening will be available in a few years. (author)

  18. Results and analysis of screening for breast cancer

    International Nuclear Information System (INIS)

    Breast cancer is the most frequent cause of death in most countries of the world. Screening of asymptomatic women can detect a large percentage of cancers at an early stage. This is the basis for a possible cure or at least a prolongation of the survival time. The percentage of minimal cancers (smaller than 1 cm without dissemination) may be as high as 48% depending on the screening modality (10% without screening), axillary lymph node involvement can be reduced to 20% (40% without screening), and the percentage of stage II to IV cancers can be reduced to 8-20% (60% without screening). Mortality in the study group over age 50 years was reduced by 30%. Disadvantages of screening are: high cost; biopsies prompted by false positive results; psychological stress for the patients; radiation hazards which have, however, become almost negligible thanks to improved technique (2 cancers in 1 million mammographies and year).

    Despite reductions in mortality rates, breast cancer remains the most common cancer and the second most common cause of cancer death in Canadian women. Organized screening programs have contributed to the decrease in breast cancer mortality by allowing for early diagnosis and treatment. The diagnostic phase following an abnormal screen has implications for patient well-being, clinical practice, and resource management in health care. We present data from British Columbia that show that improv...

    Full Text Available Dejana Braithwaite,1 Joshua Demb,1 Louise M Henderson2 1Department of Epidemiology and Biostatistics, University of California, San Francisco, CA, 2Department of Radiology, University of North Carolina, Chapel Hill, NC, USA Abstract: Breast cancer is a major cause of cancer-related deaths among older women, aged 65 years or older. Screening mammography has been shown to be effective in reducing breast cancer mortality in women aged 50–74 years but not among those aged 75 years or older. Given the large heterogeneity in comorbidity status and life expectancy among older women, controversy remains over screening mammography in this population. Diminished life expectancy with aging may decrease the potential screening benefit and increase the risk of harms. In this review, we summarize the evidence on screening mammography utilization, performance, and outcomes and highlight evidence gaps. Optimizing the screening strategy will involve separating older women who will benefit from screening from those who will not benefit by using information on comorbidity status and life expectancy. This review has identified areas related to screening mammography in older women that warrant additional research, including the need to evaluate emerging screening technologies, such as tomosynthesis among older women and precision cancer screening. In the absence of randomized controlled trials, the benefits and harms of continued screening mammography in older women need to be estimated using both population-based cohort data and simulation models.

    Prostate cancer (PC) has the highest degree of genetic transmission of any form of malignancy. In some families, the hereditary pattern is so strong as to mimic an autosomal dominance trait. We reviewed the known predisposing genetic markers to assess possible strategies for screening of families at risk. We carried out a systematic literature search using the Pubmed service of the National Center for Biotechnology Information (NCBI) and several gene libraries, including the NCBI SNP Library, the Online Mendelian Inheritance in Man® Catalog of Human Genes and Genetic Disorders (OMIM) and SNPedia to obtain known gene loci, SNPs and satellite markers associated with PC. We further cross referenced information on identified loci comparing data from different articles and gene reference sites. Whenever possible, we recorded the odds ratio (OR) for the allele associated with PC. In multiple different linkage studies, many independent PC associated loci have been identified on separate chromosomes. Genome-wide association studies have added many more markers to the set derived from linkage investigations. A subset of the alleles is associated with early onset and aggressive cancer. Due to the great heterogeneity, the OR for any one allele predicting future development of this malignancy is low. The strongest predictors are the BRCA2 mutations, and the highly penetrant G84E mutation in HOXB13. The presence of multiple risk alleles is more highly predictive than a single allele. Technical limitations on screening large panels of alleles are being overcome. It is appropriate to begin supplementing prostate specific antigen testing with alleles, such as BRCA2 and HOXB13, disclosed by targeted genomic analysis in families with an unfavorable family cancer history. Future population studies of PC should include genomic sequencing protocols, particularly in families with a history of PC and other malignancies. PMID:26638190

  4. Targeted Cancer Screening in Average-Risk Individuals.

    2015-11-01

    Targeted cancer screening refers to use of disease risk information to identify those most likely to benefit from screening. Researchers have begun to explore the possibility of refining screening regimens for average-risk individuals using genetic and non-genetic risk factors and previous screening experience. Average-risk individuals are those not known to be at substantially elevated risk, including those without known inherited predisposition, without comorbidities known to increase cancer risk, and without previous diagnosis of cancer or pre-cancer. In this paper, we describe the goals of targeted cancer screening in average-risk individuals, present factors on which cancer screening has been targeted, discuss inclusion of targeting in screening guidelines issued by major U.S. professional organizations, and present evidence to support or question such inclusion. Screening guidelines for average-risk individuals currently target age; smoking (lung cancer only); and, in some instances, race; family history of cancer; and previous negative screening history (cervical cancer only). No guidelines include common genomic polymorphisms. RCTs suggest that targeting certain ages and smoking histories reduces disease-specific cancer mortality, although some guidelines extend ages and smoking histories based on statistical modeling. Guidelines that are based on modestly elevated disease risk typically have either no or little evidence of an ability to affect a mortality benefit. In time, targeted cancer screening is likely to include genetic factors and past screening experience as well as non-genetic factors other than age, smoking, and race, but it is of utmost importance that clinical implementation be evidence-based.

  14. Anal cancer and intraepithelial neoplasia screening: A review.

    Science.gov (United States)

    Leeds, Ira L; Fang, Sandy H

    2016-01-27

    This review focuses on the early diagnosis of anal cancer and its precursor lesions through routine screening. A number of risk-stratification strategies as well as screening techniques have been suggested, and currently little consensus exists among national societies. Much of the current clinical rationale for the prevention of anal cancer derives from the similar tumor biology of cervical cancer and the successful use of routine screening to identify cervical cancer and its precursors early in the disease process. It is thought that such a strategy of identifying early anal intraepithelial neoplasia will reduce the incidence of invasive anal cancer. The low prevalence of anal cancer in the general population prevents the use of routine screening. However, routine screening of selected populations has been shown to be a more promising strategy. Potential screening modalities include digital anorectal exam, anal Papanicolaou testing, human papilloma virus co-testing, and high-resolution anoscopy. Additional research associating high-grade dysplasia treatment with anal cancer prevention as well as direct comparisons of screening regimens is necessary to develop further anal cancer screening recommendations.

    Lung cancer is a commonly occurring cancer among Korean American men. Korean Americans have lower rates of cancer screening participation than other Asian American sub-groups. However, little is known about factors that influence the cancer screening behavior of Korean immigrants. The purpose of this study was to explore facilitators of and barriers to lung cancer screening (i.e., low dose CT of the chest) among Korean immigrant men, using qualitative individual interviews and focus groups. A convenience sample of 24 Korean men who were immigrants, Washington State residents, able to speak Korean, aged 55-79, and eligible for lung cancer screening (based on current guidelines) were recruited from Korean churches and senior centers. Five focus groups (that included between two and five men) and nine individual interviews were conducted. Content analysis was used to analyze the qualitative data. Facilitators of lung cancer screening included perceptions about positive aspects of the health care system in South Korea, recommendations from others (physicians, family members, and community organizations), existing health problems and respiratory symptoms, interest in health, and the health consequences of aging. Barriers included costs of health care in the US, lack of time, lack of knowledge (about lung cancer and screening), attitudes about prevention, and lack of physician recommendation. This study adds new knowledge to a field where little information is available. It also lays the groundwork for developing culturally relevant lung cancer screening interventions for Korean Americans and the health care providers who serve them. PMID:26846627

In USA, there are more than 30.000 new cases every year. We can find many risk factors of oral cancer in our daily living. Moreover, it’s easy to find the main risk factors in our society, they are smoking, alcohol consumption, tobacco consumtion, viral infection, and bad oral hygiene.

    Asian Americans (AA) are less likely to be screened for colorectal cancer compared with non-Hispanic Whites (NHW), with a widening disparity for some AA subgroups in the early 2000s. Whether these patterns have continued in more recent years is unknown. We examined temporal trends in colorectal cancer screening among AA overall compared with NHWs and by AA subgroup (Chinese, Japanese, Korean, Filipino, South Asian, Vietnamese) using data from the 2003, 2005, 2007, and 2009 California Health Interview Surveys. Unadjusted (PR) and adjusted (aPR) prevalence ratios for colorectal cancer screening, accounting for sociodemographic, health care, and acculturation factors, were calculated for respondents ages 50 to 75 years (NHW n = 60,125; AA n = 6,630). Between 2003 and 2009, colorectal cancer screening prevalence increased from 43.3% to 64.6% in AA (P ≤ 0.001) and from 58.1% to 71.4% in NHW (P ≤ 0.001). Unadjusted colorectal cancer screening was significantly lower among AA compared with NHW in 2003 [PR = 0.74; 95% confidence interval (CI), 0.68-0.82], 2005 (PR = 0.78; 95% CI, 0.72-0.84), 2007 (PR = 0.91; 95% CI, 0.85-0.96), and 2009 (PR = 0.90; 95% CI, 0.84-0.97), though disparities narrowed over time. After adjustment, there were no significant differences in colorectal cancer screening between the two groups, except in 2003. In subgroup analyses, between 2003 and 2009, colorectal cancer screening significantly increased by 22% in Japanese, 56% in Chinese, 47% in Filipino, and 94% in Koreans. In our study of California residents, colorectal cancer screening disparities between AA and NHW narrowed, but were not eliminated and screening prevalence among AA remains below nationwide goals, including the Healthy People 2020 goal of increasing colorectal cancer screening prevalence to 70.5%.

  2. Effectiveness of ultrasound for breast cancer screening

    International Nuclear Information System (INIS)

    To evaluate the effectiveness of ultrasound (US) for breast cancer screening, we conducted a retrospective survey of 856 breast cancer patients who were preoperatively examined by mammography (MMG) and US. Their average age was 54.7 years, with a range of 24 to 92 years. MMG revealed positive findings in 771 patients (90.1%), and negative findings in the remaining 85 patients (9.9%). Likewise, US revealed positive findings in 835 patients (97.5%), and negative findings in the remaining 21 patients (2.5%). Accordingly, the proportion of positive finding in US was significantly higher than that in MMG (chi-square test, p<0.0001). The incidence of negative findings with MMG was inversely related to age: 5.8% for patients in their 70s, 5.7% for those in their 60s, 8.3% for those in their 50s, 11.1% for those in their 40s, and 26.2% for those in their 30s or younger, because of the higher breast density in younger women (chi-square test, p<0.0001). The incidence of positive findings was 99.4% for tumors 2.1 to 3.0 cm in size, 96.3% for those measuring 1.6 to 2.0 cm, 94.3% for those measuring 1.1 to 1.5 cm, and 75.4% for those less than or equal to 1.0 cm (chi-square test, p<0.0001). Among the 85 patients with negative findings by MMG, 70(82.4%) were positive and 15 (17.6%) were negative by US. As findings of calcification by US, high echo spots plus a tumor lesion were observed in 59 patients (71.1%), high echo spots only were noted in 22 patients (26.5%), and high echo spots were not seen in 2 patients (2.4%). In conclusion, parallel use of MMG and US is recommended for breast cancer screening, especially for women in their 50s or younger, to reduce the incidence of misdiagnosis. (author)

    2007-06-01

    Full Text Available Abstract Background Cervical cancer is the most common female cancer in Uganda. Over 80% of women diagnosed or referred with cervical cancer in Mulago national referral and teaching hospital have advanced disease. Plans are underway for systematic screening programmes based on visual inspection, as Pap smear screening is not feasible for this low resource country. Effectiveness of population screening programmes requires high uptake and for cervical cancer, minimal loss to follow up. Uganda has poor indicators of reproductive health (RH services uptake; 10% postnatal care attendance, 23% contraceptive prevalence, and 38% skilled attendance at delivery. For antenatal attendance, attendance to one visit is 90%, but less than 50% for completion of care, i.e. three or more visits. Methods We conducted a qualitative study using eight focus group discussions with a total of 82 participants (16 men, 46 women and 20 health workers. We aimed to better understand factors that influence usage of available reproductive health care services and how they would relate to cervical cancer screening, as well as identify feasible interventions to improve cervical cancer screening uptake. Results Barriers identified after framework analysis included ignorance about cervical cancer, cultural constructs/beliefs about the illness, economic factors, domestic gender power relations, alternative authoritative sources of reproductive health knowledge, and unfriendly health care services. We discuss how these findings may inform future planned screening programmes in the Ugandan context. Conclusion Knowledge about cervical cancer among Ugandan women is very low. For an effective cervical cancer-screening programme, awareness about cervical cancer needs to be increased. Health planners need to note the power of the various authoritative sources of reproductive health knowledge such as paternal aunts (Sengas and involve them in the awareness campaign.

    The balance between benefits and harms is delicate for cancer screening programs. By attending screening with mammography some women will avoid dying from breast cancer or receive less aggressive treatment. But many more women will be overdiagnosed, receive needless treatment, have a false......-positive result, or live more years as a patient with breast cancer. Systematic reviews of the randomized trials have shown that for every 2000 women invited for mammography screening throughout 10 years, only 1 will have her life prolonged. In addition, 10 healthy women will be overdiagnosed with breast cancer...... whether screening with mammography does more good than harm. Women invited to screening should be informed according to the best available evidence, data should be reported in absolute numbers, and benefits and harms should be reported using the same denominator so that they can be readily compared....

    To analyse computed tomography (CT) findings of interval and post-screen carcinomas in lung cancer screening. Consecutive interval and post-screen carcinomas from the Dutch-Belgium lung cancer screening trial were included. The prior screening and the diagnostic chest CT were reviewed by two experienced radiologists in consensus with knowledge of the tumour location on the diagnostic CT. Sixty-one participants (53 men) were diagnosed with an interval or post-screen carcinoma. Twenty-two (36 %) were in retrospect visible on the prior screening CT. Detection error occurred in 20 cancers and interpretation error in two cancers. Errors involved intrabronchial tumour (n = 5), bulla with wall thickening (n = 5), lymphadenopathy (n = 3), pleural effusion (n = 1) and intraparenchymal solid nodules (n = 8). These were missed because of a broad pleural attachment (n = 4), extensive reticulation surrounding a nodule (n = 1) and extensive scarring (n = 1). No definite explanation other than human error was found in two cases. None of the interval or post-screen carcinomas involved a subsolid nodule. Interval or post-screen carcinomas that were visible in retrospect were mostly due to detection errors of solid nodules, bulla wall thickening or endobronchial lesions. Interval or post-screen carcinomas without explanation other than human errors are rare. (orig.)

    In Japan, lung cancer death ranks first among men and third among women. Lung cancer death is increasing yearly, thus early detection and treatment are needed. For this reason, CT screening for lung cancer has been introduced. The CT screening services are roughly divided into three sections: office, radiology and diagnosis sections. These operations have been performed through paper-based or a combination of paper-based and an existing electronic health recording system. This paper describes an operating support system for lung cancer CT screening in order to make the screening services efficient. This operating support system is developed on the basis of 1) analysis of operating processes, 2) digitalization of operating information, and 3) visualization of operating information. The utilization of the system is evaluated through an actual application and users' survey questionnaire obtained from CT screening centers.

    objective of this study was to evaluate the information breast cancer screening units send to women invited for screening in Finland. MATERIALS AND METHODS: A questionnaire was sent to all breast cancer screening units in Finland in 2005 and 2008, and the information (eg, invitations, results letters......, leaflets) the units sent to women was collected. Results from 2005 were sent as feedback to the units. Data were analyzed descriptively, and results from the 2 years were compared. RESULTS: Screening units sent personal invitation letters usually providing fixed appointment times. Most units informed about...... participation free of charge and the benefits of detecting breast cancer early. Harm associated with screening was seldom mentioned; no unit mentioned the possibility of false-negative results or overtreatment. CONCLUSION: The screening units provided very variable information, which often was biased toward...

    The advent and refinement of sequencing technologies has resulted in a decrease in both the cost and time needed to generate data on the entire sequence of the human genome. This has increased the accessibility of using whole-genome sequencing and whole-exome sequencing approaches for analysis in both the research and clinical contexts. The expectation is that more services based on these and other high-throughput technologies will become available to patients and the wider population. Some authors predict that sequencing will be performed once in a lifetime, namely, shortly after birth. The Public and Professional Policy Committee of the European Society of Human Genetics, the Human Genome Organisation Committee on Ethics, Law and Society, the PHG Foundation and the P3G International Paediatric Platform address herein the important issues and challenges surrounding the potential use of sequencing technologies in publicly funded newborn screening (NBS) programmes. This statement presents the relevant issues and culminates in a set of recommendations to help inform and guide scientists and clinicians, as well as policy makers regarding the necessary considerations for the use of genome sequencing technologies and approaches in NBS programmes. The primary objective of NBS should be the targeted analysis and identification of gene variants conferring a high risk of preventable or treatable conditions, for which treatment has to start in the newborn period or in early childhood.

    Cervical cancer (CC) represents the fourth most common malignancy affecting women all over the world and is the second most common in developing areas. In these areas, the burden from disease remains important because of the difficulty in implementing cytology-based screening programmes. The main obstacles inherent to these countries are poverty and a lack of healthcare infrastructures and trained practitioners. With the availability of new technologies, researchers have attempted to find new strategies that are adapted to low- and middle-income countries (LMIC) to promote early diagnosis of cervical pathology. Current evidence suggests that human papillomavirus (HPV) testing is more effective than cytology for CC screening. Therefore, highly sensitive tests have now been developed for primary screening. Rapid molecular methods for detecting HPV DNA have only recently been commercially available. This constitutes a milestone in CC screening in low-resource settings because it may help overcome the great majority of obstacles inherent to previous screening programmes. Despite several advantages, HPV-based screening has a low positive predictive value for CC, so that HPV-positive women need to be triaged with further testing to determine optimal management. Visual inspection tests, cytology and novel biomarkers are some options. In this review, we provide an overview of current and emerging screening approaches for CC. In particular, we discuss the challenge of implementing an efficient cervical screening adapted to LMIC and the opportunity to introduce primary HPV-based screening with the availability of point-of-care (POC) HPV testing. The most adapted screening strategy to LMIC is still a work in progress, but we have reasons to believe that POC HPV testing makes part of the future strategies in association with a triage test that still needs to be defined.

    Full Text Available Mammography, clinical breast-examination (CBE and breast self-examination (BSE are the mainly recommended screening methods for early diagnosis of breast cancer. In recent years, guidelines concerning screening methods were revised. To date, CBE and BSE are not routinely recommended for early diagnosis of breast cancer in western countries. Due to important value in decreasing breast cancer mortality rate, mammography, is the recommended breast cancer screening method; but the changes related with the time of mammography screening is rised to notice. In 2010, the US Preventive Services Task Force (USPSTF which is one of the important health authority, guidelines concerning screening mammography were revised. Accordingly, while the mammography that is recommended for women starting aged 40 years by many health authorities, the USPSTF no longer advises routine screening mammography for women aged 40–49 and for those aged ≥75.; and biennial screening is advised for those aged 50–74. It is necessary for health professionals working in breast health area to learn the last changes concerning about breast cancer screening methods. Together with CBE and BSE, it is also important to encourage women to participate mammography screening with an understanding of its benefits and risks. In this article, it is aimed to critique new guidelines about breast cancer screening methods. It is also critiqued the potential benefits and risks of mammography that is currently considered the ‘‘gold standard’’ for breast cancer screening for women.

    Full Text Available John R van Nagell Jr, John T HoffDepartment of Obstetrics and Gynecology, University of Kentucky Chandler Medical Center/Markey Cancer Center, Lexington, KY, USAAbstract: Transvaginal ultrasonography (TVS is an integral part of all major ovarian cancer screening trials. TVS is accurate in detecting abnormalities in ovarian volume and morphology, but is less reliable in differentiating benign from malignant ovarian tumors. When used as the only screening test, TVS is sensitive, but has a low positive predictive value. Therefore, serum biomarkers and tumor morphology indexing are used together with TVS to identify ovarian tumors at high risk for malignancy. This allows preoperative triage of high-risk cases to major cancer centers for therapy while decreasing unnecessary surgery for benign disease. Ovarian cancer screening has been associated with a decrease in stage at detection in most trials, thereby allowing treatment to be initiated when the disease is most curable.Keywords: ovarian cancer, ultrasound, screening, serum Ca-125

    Highlights: • We found variation in early performance measures across screening centres. • Radiologists’ performance may play a key role in the variability. • Potential to improve the effectiveness of breast cancer screening programs. • Continuous surveillance of screening centres and radiologists is essential. - Abstract: Background: Recall for assessment in mammographic screening entails an inevitable number of false-positive screening results. This study aimed to investigate the variation in the cumulative risk of a false positive screening result and the positive predictive value across the screening centres in the Norwegian Breast Cancer Screening Program. Methods: We studied 618,636 women aged 50–69 years who underwent 2,090,575 screening exams (1996–2010. Recall rate, positive predictive value, rate of screen-detected cancer, and the cumulative risk of a false positive screening result, without and with invasive procedures across the screening centres were calculated. Generalized linear models were used to estimate the probability of a false positive screening result and to compute the cumulative false-positive risk for up to ten biennial screening examinations. Results: The cumulative risk of a false-positive screening exam varied from 10.7% (95% CI: 9.4–12.0%) to 41.5% (95% CI: 34.1–48.9%) across screening centres, with a highest to lowest ratio of 3.9 (95% CI: 3.7–4.0). The highest to lowest ratio for the cumulative risk of undergoing an invasive procedure with a benign outcome was 4.3 (95% CI: 4.0–4.6). The positive predictive value of recall varied between 12.0% (95% CI: 11.0–12.9%) and 19.9% (95% CI: 18.3–21.5%), with a highest to lowest ratio of 1.7 (95% CI: 1.5–1.9).

    Full Text Available Background: Cervical cancer is the second most common cancer among Iranian women and among the few cancers that could be easily diagnosed in the pre-malignant stage. We aimed to assess the status of cervical cancer screening in women referred to health care centres in Tabriz, northwest Iran. Materials and Methods: This descriptive-analytical study was done on 441 women referred to health care centres of Tabriz, northwest Iran. The centres were selected using the multi-stage cluster sampling method. The participants were selected from the active records of those centres. A questionnaire regarding the socio-demographic characteristics and cervical cancer screening and reasons for referring or not referring for screening was completed by the participants A P < 0.05 was considered as significant. Results: Out of the participants 49.4% of women had done the Pap smear test while 50.6% had never done this test. The main reason why women had not performed cervical cancer screening was being unaware of the importance of it (46.1%. Logistic regression analysis with adjustment showed a significant relationship between screening and awareness scores (OR = 1.17, CI = 95%:1.12-1.23, when the effect of other confounding factors [total awareness scores, risk factors (marriage or having sexual intercourse at a young age, history of obvious cervical infection, cautery, cryotherapy or repeated curettage, age and type of family planning] in screening was controlled. Conclusion: Suitable and continuous educational programmes especially for high risk women should be implemented through the health care services. Preparing educational brochures and pamphlets and providing adequate training on the necessity of early referral and marriage counseling could also be effective in improving woman′s awareness and performance.

    Deafness is the most common curable childhood handicap. It is a well recognised fact that unidentified hearing impairment can adversely affect optimal speech and language development and therefore academic, social and emotional development. Universal neonatal hearing screening programmes are implemented in many developed countries. However it is still in its early stage in India. The incidence of hearing impairment in India is 1-6 per thousand newborns screened (Paediatrics 19:155-165, 1998; Indian J Paediatr 74(6):545-549, 2007; Status of Disability in India, pp 172-185 2000). To determine the incidence of permanent hearing loss of moderate to evere variety in neonates taking care in a tertiary care rural based hospital in Gujarat. It was a non randomised observational study done for duration of 3 years. All neonates born in Shri Krishna Hospital underwent screening using two stage protocols with DPOAE test and final confirmation done with BERA. Total 2534 neonates were screened out of them 52 failed and 2482 (97.94 %) neonates passed in the 1st DPOAE test with 2.05 % refer rate. Total 7 (2 per 1000) neonates were detected with hearing impairment. 10 % neonates had one or other high risk factor. Out of high risk neonates, 1.8 % were diagnosed with hearing impairment in high risk group. Overall the follow-up rate was 72.7 %. Hospital based universal hearing screening of new born before discharge is feasible at a rural based tertiary care centre. Non specialist staff is invaluable in achieving a satisfactory referral rate with two stage hearing screening protocol. However, more efficacious tracking and follow up system is needed to improve the follow up rate for diagnosis. PMID:26693457

    Objective: The aim of this study was to use lung cancer targeting binding polypeptide ZS-9 to screen cDNA library of human lung cancer and obtain ZS-9 specific ligand to confirm tumor marker of non small-cell lung cancer. Methods: Artificially synthesize biotin labeled peptide ZS-9, anchored ZS-9 in the enzyme label plate coupled by avidin, used ZS-9 as probe to screen cDNA library of human lung cancer, after screening, obtained bacteriophage clone specifically binding with anchored polypeptide ZS-9. Extracted plasmid of bacteriophage and performed sequencing after amplified by PCR. Results: It was demonstrated by bioinformatic analysis on the sequence of ligand binded by lung cancer specific peptide ZS-9 that the ligand was the cytoskeletal protein periplakin on the surface of lung cancer cells, suggesting that periplakin might be a new marker for non-small-cell lung cancer in lung cancer. Conclusion: Use specific lung cancer binding peptide to screen new tumor marker periplakin in lung cancer and further studies on its biologic functions in genesis and development of lung cancer are still needed.

  1. Study of mammography in mass screening for breast cancer

    International Nuclear Information System (INIS)

    In order to examine the rate of correct diagnosis by mammography at initial mass screening for breast cancer, we carried out a retrospective study of mammography findings in 267 cases of breast cancer detected at Asahikawa Cancer Screening Center. The screening was performed by physical examination, and in cases where disease was suspected, mammography, ultrasonography, and needle biopsy were done. Mammographically, 172 cases (64.4%) were cancer-positive, 58 cases (21.7%) were suspicious for cancer, and 37 cases (13.9%) were cancer-negative. Patients below 50 years of age and those with tumors of small diameter (<20 mm) showed a significantly lower rate of cancer positivity than patients aged 50 years or more and those with tumors 20 mm or more in diameter. Mammographic abnormalities were not specific, since these changes were also found in normal subjects and patients with benign diseases. Therefore, we concluded that mammography without physical examination at initial mass screening has a high risk of missing breast cancer. Mass screening for breast cancer should be performed by physical examination involving inspection and palpation at the first instance. If any suspicious findings are obtained, mammography, ultrasonography, and needle biopsy should be done. (author)

    Full Text Available Mutation spectrum varies significantly in different parts and different ethnic groups of India. Social factors such as preference to marry within the community and among 1st degree relatives (consanguinity play an important role in impeding the gene pool of the disease within the community and so in society by and large. The present paper discusses the role of consanguinity in profiling of beta thalassemia mutation, and thus the approach for prenatal screening and prevention based awareness programme. Clinically diagnosed 516 cases of beta thalassemia were screened at molecular level. A detailed clinical Proforma was recorded with the information of origin of the family, ethnicity, and consanguinity. The present study reports that subjects originating from Uttar Pradesh, Uttarakhand, Bihar, and Jharkhand have c.92+5G>C and c.124_127delTTCT mutation as the commonest mutation compared to the subjects hailing from Madhya Pradesh and Chhattisgarh and Nepal where sickle mutation was found more common. In 40 consanguineous unions more common and specific beta mutations with higher rate of homozygosity have been reported. This consanguinity-based data helps not only in deciding target oriented prenatal diagnostic strategies but also in objective based awareness programmes in prevention of thalassemia major birth.

  4. Screening for breast cancer in a high-risk series

    International Nuclear Information System (INIS)

    A unique cohort of women at increased risk of breast cancer because of prior X-ray treatment of acute mastitis and their selected high-risk siblings were offered periodic breast cancer screening including physical examination of the breasts, mammography, and thermography. Twelve breast cancers were detected when fewer than four would have been expected based on age-specific breast cancer detection rates from the National Cancer Institute/American Cancer Society Breast Cancer Demonstration Detection Projects. Mammography was positive in all cases but physical examination was positive in only three cases. Thermography was an unreliable indicator of disease. Given the concern over radiation-induced risk, use of low-dose technique and of criteria for participation that select women at high risk of breast cancer will maximize the benefit/risk ratio for mammography screening

    Full Text Available Background: The primary objective was to examine and compare the breast cancer screening adherence rates between black (African American and Afro-Caribbean and Hispanic (foreign born Hispanic and US-born Hispanic subpopulations. Methods: Study data was collected in community settings in New York City between the years of 2011-2012. Participants (N=592 were black and Hispanic individuals who attended a breast cancer screening community outreach program. Breast cancer screening rates as well as demographic data were collected. Results: Results revealed that Afro-Caribbean and foreign-born Hispanics are at a greater risk for non-adherence in breast cancer screening compared with African Americans and US-born Hispanics. Conclusions: The majority of breast screening research and community outreach programs categorize people into broad racial and ethnic groups (e.g., black and Hispanic. The results revealed significant variability within these broader racial/ethnic categories with regard to breast cancer screening. Community outreach programs and future research efforts should target the subpopulations that are at particular risk for breast cancer screening non-adherence.

    Depletion of the ozone layer has been observed on a global scale. Ozone depletion increases the amount of biologically harmful solar ultraviolet radiation (UV) that reaches the surface of the Earth, leading to an increased incidence of skin cancer. We previously reported the prevalence and incidence of actinic keratosis (AK) in Kasai City, which is located almost at the center of Japan. To evaluate the effects of different ambient annual UV doses on the prevalence and incidence of non-melanoma skin cancer and AK in Japan, we screened for skin cancer on Ie Island in Okinawa at the southern end of Japan, where the annual cumulative dose of UV is assumed to be the highest in Japan. The island had a population of 5562 in 1993. A prospective 4-year population-based study on the prevalence and incidence of cutaneous neoplasms was conducted by examining the sun-exposed skin of people over 40 years of age living on Ie Island. In 1993 1996, 86 cases of AK, nine of basal cell carcinoma (BCC), and two of squamous cell carcinoma were identified. The annual prevalence of AK on Ie Island was 1159.4 in 1993, 572.8 in 1994, 1014.3 in 1995 and 988.9 per 100000 Japanese in 1996. These values were significantly higher than those in Kasai City. The annual age-adjusted odds ratios for AK of Ie Island to Kasai City were 2.79, 1.38, 2.45 and 2.39, respectively. The incidences of AK on Ie Island per 100,000 were 637.0 in 1995 and 625.5 in 1996, which were also significantly higher than those in Kasai City (223.6 in 1993 and 171.2 in 1994). The prevalence of BCC was 123.6 and the incidence was 26.1. Together with our previous reports, the present results show a possible inverse relationship between the prevalence and incidence of AK and latitude among Japanese people. PMID:10215187

    Emerging results indicate that screening improves survival of patients with colorectal cancer. Therefore, screening programs are already implemented or are being considered for implementation in Asia, Europe and North America. At present, a great variety of screening methods are available including colono- and sigmoidoscopy, CT- and MR-colonography, capsule endoscopy, DNA and occult blood in feces, and so on. The pros and cons of the various tests, including economic issues, are debated. Although a plethora of evaluated and validated tests even with high specificities and reasonable sensitivities are available, an international consensus on screening procedures is still not established. The rather limited compliance in present screening procedures is a significant drawback. Furthermore, some of the procedures are costly and, therefore, selection methods for these procedures are needed. Current research into improvements of screening for colorectal cancer includes blood-based biological markers, such as proteins, DNA and RNA in combination with various demographically and clinically parameters into a "risk assessment evaluation" (RAE) test. It is assumed that such a test may lead to higher acceptance among the screening populations, and thereby improve the compliances. Furthermore, the involvement of the media, including social media, may add even more individuals to the screening programs. Implementation of validated RAE and progressively improved screening methods may reform the cost/benefit of screening procedures for colorectal cancer. Therefore, results of present research, validating RAE tests, are awaited with interest. PMID:21854094

    Full Text Available INTRODUCTION: Migrant Chinese constitute a significant and increasing proportion of New Zealand women. They have lower rates of participation in breast cancer screening than other New Zealanders, but reasons for this are unknown. The aim of this study was to investigate factors affecting Chinese women’s understanding of, and access to, breast health services, to better understand reasons for low participation in screening and their experiences of breast cancer clinic care. METHODS: The participants were 26 Chinese migrant women—19 recruited in the community and seven recruited from 17 eligible women attending a breast clinic between 2008 and 2010 in Wellington, New Zealand. The design was that of a qualitative study, using semi-structured interviews and thematic content analysis. FINDINGS: There were low levels of awareness about the national breast screening programme and limited engagement with preventive primary care services. Concerns about privacy and a range of communication difficulties were identified that related to oral language, lack of written information in Chinese, and limited understanding about Chinese perceptions of ill health and traditional Chinese medicine by New Zealand health professionals. CONCLUSION: Addressing communication barriers for Chinese migrant women has the potential to raise awareness about breast cancer and breast health, and to increase successful participation in breast cancer screening. Greater efforts are needed to ensure this group has an understanding of, and is engaged with a primary care provider. Such efforts are key to improving health for this growing sector of the New Zealand population.

    Suboptimal diets, sedentary lifestyles, overweight and obesity expose two-thirds of women in England aged over 50 to a heightened risk of lifestyle-related morbidities. The UK's NHS Breast Cancer Screening Programme now reaches 75% of all women aged 53-64 but provides only mammography screening. This cross-sectional survey of 413 women attending two NHS breast screening clinics in North Yorkshire found that the majority of women were interested in having diet and exercise advice at screening clinics and anticipated a neutral or positive effect on their future screening appointments. Interest was highest among older, less educated and overweight women suggesting that this may be a particularly effective medium for reaching higher risk subgroups. Women showed most interest in problem-solving advice, which provided short-term, life-enhancing benefits such as looking and feeling better, having more energy, losing weight and reducing menopausal symptoms, as well as potentially reducing their disease risk. Most appeared to find doing sufficient exercise more problematic than eating healthily and this might be exacerbated by low awareness of exercise guidelines. Given a choice, preferences were to access advice in leaflets or one to one from an expert; however, many younger, professional women were also interested in computer access. Findings indicate the need first for flexible, multi-level access, combining some broad-based information dissemination with pathways to more personalized support and secondly for the relevant 'consumer benefits' associated with better diet and exercise to be promoted as well as longer-term disease prevention. Overall, this study indicates that the UK's NHS Breast Cancer Screening Programme may be uniquely placed to provide health-enhancing advice as well as mammography screening to the majority of women in England, throughout the course of their mid-life.

    BACKGROUND: Social support may have an impact on screening participation. We studied the association between social support in 2006, defined as frequencies of contacts, instrumental support and emotional support and participation in breast cancer screening in 2008-09. METHODS: This population......-based cohort study included 4512 women who had participated in a Health Survey in 2006 and who also were in the target group for the first round of organized breast cancer screening in the Central Denmark region in 2008-09. RESULTS: Women with infrequent contacts with friends and family in 2006 were more...... non-participation in breast cancer screening in 2008-09. Targeted social interventions may, therefore, have an impact on future screening behaviour, which calls for further research....

    Full Text Available Introduction: An increased number of screen failure patients in a clinical trial increases time and cost required for the recruitment. Assessment of reasons for screen failure can help reduce screen failure rates and improve recruitment. Materials and Methods: We collected retrospective data of human epidermal growth factor receptor (HER2 positive Indian breast cancer patients, who failed screening for phase 3 clinical trials and ascertained their reasons for screen failure from screening logs. Statistical comparison was done to ascertain if there are any differences between private and public sites. Results: Of 727 patients screened at 14 sites, 408 (56.1% failed screening. The data on the specific reasons for screen failures was not available at one of the public sites (38 screen failures out of 83 screened patients. Hence, after excluding that site, further analysis is based on 644 patients, of which 370 failed screening. Of these, 296 (80% screen failure patients did not meet selection criteria. The majority -266 were HER2 negative. Among logistical issues, 39 patients had inadequate breast tissue sample. Sixteen patients withdrew their consent at private sites as compared to six at public sites. The difference between private and public sites for the above three reasons was statistically significant. Conclusion: Use of prescreening logs to reduce the number of patients not meeting selection criteria and protocol logistics, and patient counseling to reduce consent withdrawals could be used to reduce screen failure rate.

    INTRODUCTION: A reason for not recommending subtotal hysterectomy is the risk of cervical pathology. We aimed to evaluate cervical cancer screening and to describe cervical pathology after subtotal and total hysterectomy for benign indications. METHODS: Data regarding adherence to screening.......7% were not screened. We found a minimum of one abnormal test in 28 (10.8%) after subtotal hysterectomy and one after total hysterectomy. No cervical cancers were found. CONCLUSIONS: Adherence to cervical cancer screening after subtotal hysterectomy in a Danish population is suboptimal and some patients...... have unnecessary tests performed after total hysterectomy. Clarification of the use of cervical/vaginal smears after hysterectomy is needed to identify women at risk of cervical dysplasia or cancer.

    This research aims to quantify the impact of reminder invitations on uptake and cancer detection in Ireland. Examination of BreastCheck\\'s clinical database (2000-2010) to determine number of women screened following first invitation and after reminder; comparison by age group and screening phase with outcomes of recall rate, cancer detection and true positive rates. Of 819,182 first invitations sent 448,974 (54.8%) women attended. 245,157 (66.2%) women attended after reminder invitations, increasing uptake by 29.9% to 694,131 (84.7%) and cancers detected by 1,550 (35%). Women awaiting a reminder were less likely recalled for assessment 9,555 (3.9%) than respondents to first invitation 2,887 (4.04%) (p=0.004). Younger, mainly initial women were more likely recalled for assessment after first invitation. There was no difference between cohorts for cancer detection rate or true positive rate. Reminders increased uptake, supporting international evidence. For programme efficiency attendance at first invitation is optimal. For maximum programme effectiveness attendance must be encouraged with reminders.

  3. Environmental scan of anal cancer screening practices: worldwide survey results

    International Nuclear Information System (INIS)

    Anal squamous cell carcinoma is rare in the general population but certain populations, such as persons with HIV, are at increased risk. High-risk populations can be screened for anal cancer using strategies similar to those used for cervical cancer. However, little is known about the use of such screening practices across jurisdictions. Data were collected using an online survey. Health care professionals currently providing anal cancer screening services were invited to complete the survey via email and/or fax. Information was collected on populations screened, services and treatments offered, and personnel. Over 300 invitations were sent; 82 providers from 80 clinics around the world completed the survey. Fourteen clinics have each examined more than 1000 patients. Over a third of clinics do not restrict access to screening; in the rest, eligibility is most commonly based on HIV status and abnormal anal cytology results. Fifty-three percent of clinics require abnormal anal cytology prior to performing high-resolution anoscopy (HRA) in asymptomatic patients. Almost all clinics offer both anal cytology and HRA. Internal high-grade anal intraepithelial neoplasia (AIN) is most often treated with infrared coagulation (61%), whereas external high-grade AIN is most commonly treated with imiquimod (49%). Most procedures are performed by physicians, followed by nurse practitioners. Our study is the first description of global anal cancer screening practices. Our findings may be used to inform practice and health policy in jurisdictions considering anal cancer screening

    Colorectal cancer is currently the second most common cancer among Korean males and the fourth most common among females. Since the majority of colorectal cancer case present following the prolonged transformation of adenomas into carcinomas, early detection and removal of colorectal adenomas are vital methods in its prevention. Considering the increasing incidence of colorectal cancer and polyps in Korea, it is very important to establish national guidelines for colorectal cancer screening and polyp detection. The proposed guidelines have been developed by the Korean Multi-Society Task Force using evidence-based methods. Systematic reviews and meta-analyses have been used to form the statements contained in the guidelines. This paper discusses the epidemiology of colorectal cancers and adenomas in Korea as well as optimal methods for screening of colorectal cancer and detection of adenomas including fecal occult blood tests, radiologic tests, and endoscopic examinations.

    Lung cancer has remained the leading cause of death worldwide among all cancers. The dismal 5-year survival rate of 16% is in part due to the lack of symptoms during early stages and lack of an effective screening test until recently. Chest X-ray and sputum cytology were studied extensively as potential screening tests for lung cancer and were conclusively proven to be of no value. Subsequently, a number of studies compared computed tomography (CT) with the chest X-ray. These studies did identify lung cancer in earlier stages. However, they were not designed to prove a reduction in mortality. Later trials have focused on low-dose CT (LDCT) as a screening tool. The largest US trial – the National Lung Screening Trial (NLST) – enrolled approximately 54,000 patients and revealed a 20% reduction in mortality. While a role for LDCT in lung cancer screening has been established, the issues of high false positive rates, radiation risk, and cost effectiveness still need to be addressed. The guidelines of the international organizations that now include LDCT in lung cancer screening are reviewed. Other methods that may improve earlier detection such as positron emission tomography, autofluorescence bronchoscopy, and molecular biomarkers are also discussed. PMID:26528348

  11. Analysis of previous screening examinations for patients with breast cancer

    International Nuclear Information System (INIS)

    We wanted to improve the quality of subsequent screening by reviewing the previous screening of breast cancer patients. Twenty-four breast cancer patients who underwent previous screening were enrolled. All 24 took mammograms and 15 patients also took sonograms. We reviewed the screening retrospectively according to the BI-RADS criteria and we categorized the results into false negative, true negative, true positive and occult cancers. We also categorized the causes of false negative cancers into misperception, misinterpretation and technical factors and then we analyzed the attributing factors. Review of the previous screening revealed 66.7% (16/24) false negative, 25.0% (6/24) true negative, and 8.3% (2/24) true positive cancers. False negative cancers were caused by the mammogram in 56.3% (9/16) and by the sonogram in 43.7% (7/16). For the false negative cases, all of misperception were related with mammograms and this was attributed to dense breast, a lesion located at the edge of glandular tissue or the image, and findings seen on one view only. Almost all misinterpretations were related with sonograms and attributed to loose application of the final assessment. To improve the quality of breast screening, it is essential to overcome the main causes of false negative examinations, including misperception and misinterpretation. We need systematic education and strict application of final assessment categories of BI-RADS. For effective communication among physicians, it is also necessary to properly educate them about BI-RADS

    Hematopoietic stem cell transplant (HCT) recipients have a substantial risk of developing secondary solid cancers, particularly beyond 5 years after HCT and without reaching a plateau overtime. A working group was established through the Center for International Blood and Marrow Transplant Research and the European Group for Blood and Marrow Transplantation with the goal to facilitate implementation of cancer screening appropriate to HCT recipients. The working group reviewed guidelines and methods for cancer screening applicable to the general population and reviewed the incidence and risk factors for secondary cancers after HCT. A consensus approach was used to establish recommendations for individual secondary cancers. The most common sites include oral cavity, skin, breast and thyroid. Risks of cancers are increased after HCT compared with the general population in skin, thyroid, oral cavity, esophagus, liver, nervous system, bone and connective tissues. Myeloablative TBI, young age at HCT, chronic GVHD and prolonged immunosuppressive treatment beyond 24 months were well-documented risk factors for many types of secondary cancers. All HCT recipients should be advised of the risks of secondary cancers annually and encouraged to undergo recommended screening based on their predisposition. Here we propose guidelines to help clinicians in providing screening and preventive care for secondary cancers among HCT recipients. PMID:25822223

    The National Lung Screening Trial (NLST) compared two ways of detecting lung cancer: low-dose helical computed tomography (CT) and standard chest X-ray. Both chest X-rays and low-dose helical CT scans have been used to find lung cancer early, but the effects of these screening techniques on lung cancer mortality rates had not been determined. NLST enrolled 53,454 current or former heavy smokers from 33 sites and coordinating centers across the United States. | The National Lung Screening Trial (NLST) compared two ways of detecting lung cancer: participants who received low-dose helical CT scans had a 20% lower risk of dying from lung cancer than participants who received standard chest X-rays.

    The introduction of low dose lung cancer helical CT screening to the clinical site has been the fundamental basis of research on Computer Aided Diagnosis (CAD) using thoracic CT images. Our purpose is the early detection of lung cancer leading to its early treatment, in order to reduce the mortality of lung cancer. From multi-slice CT, lung cancer screening has been activated more. Since CT screening contains a lot of images compared with the conventional X-ray, research and development on the utilization of computer and network using the new diagnosis support technology is required. Due to the demand from actual clinical site, the research group from The University of Tokushima has started the research and development of CAD using lung cancer CT images. We report the result and the future works. (author)

    International Nuclear Information System (INIS)

    Objective: To discuss the values of three screening methods for the detection of early breast cancer, and to analyze the features of the screening cancer. Methods: The first screening of breast cancer were performed in 5307 women who aged from 20 to 76 years with median age of 49 years. The three screening methods included physical examination with ultrasound and mammography, physical examination with mammography and mammography only. The rate of recall, biopsy, cancer detection of three methods were analyzed and the mammographic findings were reviewed. Chi-square test or Fisher's exact test were used for the statistics. Results: The recall rates were 4.90% (49/1001), 6.90% (166/2407) and 4. 48% (85/1899) in three methods respectively, the biopsy rates were 1.60% (16/1001), 1.04% (25/2407) and 0.63% (12/1899), the cancer detection rates were 0.50% (5/1001), 0.17% (4/2407) and 0 (0/1899). There were statistical differences among the three groups (χ2=12.99,6.264,8.764, P<0.05). Physical examination with ultrasound and mammography had the highest cancer detection rate, ten breast cancers were detected and 8 were early stage breast cancer. Of seven cancers detected by mammography, only two were found by ultrasound. A cluster of calcifications were found in 2 cases, linear calcifications in 2 cases. One case presented as a asymmetric density, one as a asymmetric density with calcifications, one as multiple nodules with a cluster of calcifications. Two breast cancers presented as asymmetric density were missed on mammography and diagnosed correctly after retrospective review. Conclusion: Physical examination with ultrasound and mammography is the best method for breast cancer screening. The breast cancer can be detected by mammography earlier than other methods.

  17. Modelling breast cancer in a TB fluoroscopy cohort: Implications for the Dutch mammography screening

    International Nuclear Information System (INIS)

    Breast cancer incidence in a tuberculosis fluoroscopy cohort has been modelled with a two-stage carcinogenesis model. The relatively simple model, in which hormonal influences only affect the number of sensitive target cells, fits the data very well. Under the assumption that individual hormonal differences average out, and with a relative biological effectiveness for mammographic X rays of 1, the model yields ∼10 fatal breast cancer cases induced by the entire Dutch screening programme over a period of 25 y. This is much lower than derived from standard ICRP risk estimates and should be compared with the number of lives saved, which is estimated at ∼350 y-1. As the extent of screening is currently being reconsidered in the Netherlands and elsewhere, this is an important result. (authors)

    Cytology-based nation-wide cervical screening has led to a substantial reduction of the incidence of cervical cancer in western countries. However, the sensitivity of cytology for the detection of high-grade precursor lesions or cervical cancer is limited; therefore, repeated testing is necessary to achieve program effectiveness. Additionally, adenocarcinomas and its precursors are often missed by cytology. Consequently, there is a need for a better screening test. The insight that infection with high-risk human papillomavirus (hrHPV) is the causal agent of cervical cancer and its precursors has led to the development of molecular tests for the detection of hrHPV. Strong evidence now supports the use of hrHPV testing in the prevention of cervical cancer. In this review, we will discuss the arguments in favor of, and concerns on aspects of implementation of hrHPV testing in primary cervical cancer screening, such as the age to start hrHPV-based screening, ways to increase screening attendance, requirements for candidate hrHPV tests to be used, and triage algorithms for screen-positive women.

  2. The impact of radiologists' expertise on screen results decisions in a CT lung cancer screening trial

    International Nuclear Information System (INIS)

    To evaluate the impact of radiological expertise on screen result decisions in a CT lung cancer screening trial. In the NELSON lung cancer screening trial, the baseline CT result was based on the largest lung nodule's volume. The protocol allowed radiologists to manually adjust screen results in cases of high suspicion of benign or malignant nodule nature. Participants whose baseline CT result was based on a solid or part-solid nodule were included in this study. Adjustments by radiologists at baseline were evaluated. Histology was the reference for diagnosis or to confirm benignity and stability on subsequent CT examinations. A total of 3,318 participants (2,796 male, median age 58.0 years) were included. In 195 participants (5.9 %) the initial baseline screen result was adjusted by the radiologist. Adjustment was downwards from positive or indeterminate to negative in two and 119 participants, respectively, and from positive to indeterminate in 65 participants. None of these nodules turned out to be malignant. In 9/195 participants (4.6 %) the screen result was adjusted upwards from negative to indeterminate or indeterminate to positive; two nodules were malignant. In one in 20 cases of baseline lung cancer screening, nodules were reclassified by the radiologist, leading to a reduction of false-positive screen results. (orig.)

  3. Evaluation of the population dose to the UK population from the National Health Service breast screening programme

    International Nuclear Information System (INIS)

    In the United Kingdom National Health Service Breast Screening Programme (NHSBSP), women aged between 50 and 70 y are invited for mammography every 3 y. Screening histories for each woman, over four screening rounds, were analysed. Data from five screening programmes were used to select 57 425 women into the study. Cases were selected on the basis of being between the ages of 50 and 53 at the start of the NHSBSP (i.e. between 1989 and 1992). Assessment of the outcome for each screening round for each woman involved assigning a simple outcome code. Each of the possible pathways through the four screening rounds was analysed. This comprises of 500 possible pathways. This data enabled the following information to be determined: (i) The number of times a woman attended the screening programme. (ii) The number of women referred for assessment at each screening round. This information may be used to deduce the population dose to this group of women averaged over four screening rounds. Patient doses have been monitored since the programme's inception and are typically 4.5 mGy for two-view screening. It is possible to determine the mean glandular dose received by this cohort of women over four screening rounds by multiplying the number of examinations by the mean glandular dose for a typical woman. Allowance has to be made for the number of projections taken at each screening round. Once a woman has been screened, she may be invited back for further assessment if an abnormality is found on her mammogram. A stereotactic attachment is used to determine where to place the biopsy device. Although the dose received during a normal screening mammogram is well known, the dose for a stereotactic procedure and other assessment procedures is less well known, partly because only a small part of the breast is directly irradiated during stereo-taxis. However, the woman may have multiple exposures during this stage. A prospective survey of doses was completed to deduce the mean

    Full Text Available Abstract Background Despite the existence of different screening methods, the response to cancer screening is poor among Malaysians. The current study aims to examine cancer patients’ perceptions of cancer screening and early diagnosis. Methods A qualitative methodology was used to collect in-depth information from cancer patients. After obtaining institutional ethical approval, patients with different types and stages of cancer from the three major ethnic groups (Malay, Chinese and Indian were approached. Twenty semi-structured interviews were conducted. All interviews were audiotaped, transcribed verbatim, and translated into English for thematic content analysis. Results Thematic content analysis yielded four major themes: awareness of cancer screening, perceived benefits of cancer screening, perceived barriers to cancer screening, and cues to action. The majority of respondents had never heard of cancer screening before their diagnosis. Some participants reported hearing about mammogram and Pap smear tests but did not undergo screening due to a lack of belief in personal susceptibility. Those who had negative results from screening prior to diagnosis perceived such tests as untrustworthy. Lack of knowledge and financial constraints were reported as barriers to cancer screening. Finally, numerous suggestions were given to improve screening behaviour among healthy individuals, including the role of mass media in disseminating the message ‘prevention is better than cure’. Conclusions Patients’ narratives revealed some significant issues that were in line with the Health Belief Model which could explain negative health behaviour. The description of the personal experiences of people with cancer could provide many cues to action for those who have never encountered this potentially deadly disease, if incorporated into health promotion activities.

  6. Quality control in screening programs for cervical cancer

    International Nuclear Information System (INIS)

    The malignancy of the cervix is one of the few locations avoidable cancers, if detected before it progresses to the infiltration. The most efficient way of early detection is through a screening program to provide women undertaking a regular and quality Pap smear. If this test results abnormal, the program offers easier access to specialized care, effective treatment, and follow-up. The objective of this article is to present usefulness of methods for quality control used in screening programs for cervical cancer to detect their inadequacies. Here are some factors and conditions that must be considered in each of the steps to take, for a cervical cancer screening program to be successful and to meet the objectives proposed in reducing mortality due to this cause. This document contains some useful indexes calculated to ensure quality throughout the process. There should be the measurement of quality throughout the screening process that allows collecting of reliable data as well as correcting deficiencies

  7. Transillumination in breast cancer detection: screening failures and potential

    International Nuclear Information System (INIS)

    This prospective study of 1265 women referred to a multimodality breast diagnostic center compares the sensitivity for breast cancer detection of state-of-the-art transillumination light scanning and film-screen mammography. Of 33 biopsy-proven cancers, transillumination light scanning detected 58%, while mammography detected 97% of the cancers. Light scanning did detect 55% of the nonpalpable breast cancers, and 30% of those tumors smaller than 1 cm. Detection of breast cancer by light scanning was affected by breast size, but not architecture, and was directly related to tumor size. Although transillumination light scanning can detect some small curable breast cancers (smaller than 1 cm), it does not do so at a sensitivity adequate for screening

    Full Text Available Abstract Background Breast cancer remains an important public health problem. This study aimed to investigate about female knowledge of breast cancer and self-reported practice of breast self-examination in Iran. Methods This was a population-based survey carried out in Tehran, Iran. Data were collected via a structured questionnaire containing 15 questions on demographic status, history of personal and family breast problems, subjective knowledge about breast cancer covering its symptoms, the screening methods and practice of breast self-examination (BSE. A trained female nurse interviewed each respondent. Analysis included descriptive statistics and the Chi-squared test where necessary. Results A total of 1402 women were interviewed. The mean age of respondents was 43.4 (SD = 14.4 years; most were married (85%, and without any personal (94% and family history (90% of breast problems. It was found that 64% of the respondents were familiar with breast cancer and 61% (n = 851 believed that 'the disease is relatively common among women in Iran'. Most women (44% perceived a painless mass as a breast cancer symptom. Overall, 61% of the respondents stated that they knew about breast cancer screening programs and most indicated that electronic media (television 34% and radio 14% were their source of information. Only 17% of women said that 'they were conducting regular breast self-examination'. The main reason for women not doing breast self-examination was due to the fact that they did not know how to do it (64%. The findings indicated that performing breast self-examination is significantly related to: age, marital status, education, knowledge of breast cancer and knowledge about breast cancer screening programs (p Conclusion This descriptive study provides useful information that could be utilized by both researchers and those involved in public health programmes. The findings indicated that the women awareness of breast cancer warning signs

    Drug candidates often fail in preclinical and clinical testing because of reasons of efficacy and/or safety.It would be time- and cost-efficient to have screening models that reduce the rate of such false positive candidates that appear promising at first but fail later.In this regard,it would be particularly useful to have a rapid and inexpensive whole animal model that can pre-select hits from high-throughput screens but before testing in costly rodent assays.Drosophila melanogaster has emerged as a potential whole animal model for drug screening.Of particular interest have been drugs that must act in the context of multi-cellularity such as those for neurological disorders and cancer.A recent review provides a comprehensive summary of drug screening in Drosophila,but with an emphasis on neurodegenerative disorders.Here,we review Drosophila screens in the literature aimed at cancer therapeutics.

    Full Text Available Casein kinase I is a group of ubiquitous Serine/Threonine kinases that have been implicated in both normal cellular functions and several pathological conditions including Alzheimer’ s disease and cancer. Recent findings in colon and pancreatic cancer have brought tremendous attention to these molecules as potential therapeutic targets in treatment of digestive cancers. In this review, we summarize up to date what is known about this family of kinases and their involvement in carcinogenesis and other pathological conditions. Our emphasis is on their implications in digestive cancers and their potential for cancer screening and therapy.

Since the National Lung Screening Research Team (NLSRT (1 published the impressive results showing a 20% reduction in lung cancer mortality, the debate on when and if to initiate a national lung cancer screening program has been at the forefront of debate. The American Lung Association and American Cancer Society have issued statements that are not guidelines, but did offer insight on the price we pay for earlier lung cancer detection and reduction in mortality…which is the increased rates of false positives detected and increased rates of biopsies. The US Task Force on Lung Cancer Screening has yet to decide on a screening program and have yielded a statement that neither supports nor refutes the current level of evidence. Prior to the NLSRT study there were others that showed conflicting results on …

    Background Breast and colon cancer screening in rural community clinics is underused. Objective To evaluate the effectiveness and cost-effectiveness of alternative interventions designed to promote simultaneous screening for breast and colon cancer in community clinics. Methods A 3-arm, quasi-experimental evaluation was conducted during May 2008-August 2011 in 8 federally qualifed health clinics in predominately rural Louisiana. Baseline screening rates reported by the clinics was <10% for breast cancer (using mammography) and 1%-2% for colon cancer (using the fecal occult blood test [FOBT]). 744 women aged 50 years or older who were eligible for routine mammography and an FOBT were recruited. The combined screening efforts included: enhanced care; health literacy-informed education (education alone), or health literacy-informed education with nurse support (nurse support). Results Postintervention screening rates for completing both tests were 28.1% with enhanced care, 23.7% with education alone, and 38.7% with nurse support. After adjusting for age, race, and literacy, patients who received nurse support were 2.21 times more likely to complete both screenings than were those who received the education alone (95% confidence interval [CI], 1.12-4.38; P = .023). The incremental cost per additional woman completing both screenings was $3,987 for education with nurse support over education alone, and $5,987 over enhanced care. Limitations There were differences between the 3 arms in sociodemographic characteristics, literacy, and previous screening history. Not all variables that were significantly different between arms were adjusted for, therefore adjustments for key variables (age, race, literacy) were made in statistical analyses. Other limitations related generalizability of results. Conclusions Although joint breast and colon cancer screening rates were increased substantially over existing baseline rates in all 3 arms, the completion rate for both tests was

  20. Role of prevention and screening in epithelial ovarian cancer

    Directory of Open Access Journals (Sweden)

    Peddireddi Reddi Rani

    2015-08-01

    Full Text Available Epithelial ovarian carcinoma is a disease with poor prognosis and high mortality among gynaecological cancers due to inaccessibility of ovary for inspection or sampling and lack of proper screening methods. Strategies to detect early ovarian cancer include estimation of serum CA-125 and transvaginal ultrasound (TVS for morphological index. Studies have shown that screening of asymptomatic average risk post-menopausal women did not show any benefit and are associated with false positive results which may lead to unnecessary surgery and resultant morbidity. The risks outweigh benefits. Present recommendation is to screen high risk women especially hereditary cancers and offer risk reducing surgery when needed. Prophylactic salpingectomy/oophorectomy may offer the opportunity to prevent ovarian cancer. More trials and more research in newer biomarkers are needed.

  5. Radiologic aspects of breast cancers detected through a breast cancer screening program

    International Nuclear Information System (INIS)

    Early detection in breast cancer and reduced mortality in women with this disease is today attributed to widespread use of mammography. High-quality performance is essential in all steps of breast cancer screening programs in order to avoid unnecessary anxiety and surgery in the women concerned. This report presents radiologic aspects of screening cancers. A total of 8370 asymptomatic women aged 50-69 years were screened with 2-view mammography, of which only 70 (0.84 percent) were selected for surgery after a thorough work-up. Cancers were verified histologically in 61 women and 9 showed non-malignant histology, giving a cancer detection rate of 7.3 cancers per thousand screened asymptomatic women. The benign/malignant ratio in the operated cases is thus approximately 1:7. The cancers detected showed all existing types of mammographic features where 77 percent (47 cases) showed rather typical findings, such as spiculated densities both with and without microcalcifications. The results indicate that surgery can be minimized without impairing the breast cancer detection rate. Radiologists in screening programs should be aware that a large proportion of non-palpable breast cancers present in rather unconventional forms. This point is important in order to maintain a high cancer detection rate and thereby justify the widespread use of mammography as a screening tool for breast cancer in asymptomatic women.

    Full Text Available Abstract Background The major limit to colorectal cancer screening effectiveness is often low compliance. We studied the reasons for non compliance and determinants of compliance to faecal occult blood tests in Lazio, Italy. Methods This is a case-control study nested within a trial that tested the effect of type of test and provider on colorectal cancer screening compliance. Non compliant trial subjects were classified as cases, and compliant subjects were classified as controls. We sampled 600 cases and 600 controls matched by their general practitioner, half were invited for screening at the hospital, and the other half directly at their general practitioner's office. Cases and controls answered questions on: distance from test provider, logistical problems, perception of colorectal cancer risk, confidence in screening efficacy, fear of results, presence of colorectal cancer in the family, and gastrointestinal symptoms. Results About 31% of cases never received the letter offering free screening, and 17% of the sampled population had already been screened. The first reported reason for non-compliance was "lack of time" (30%; the major determinant of compliance was the distance from the test provider: odds ratio >30 minutes vs Conclusion To increase compliance, screening programmes must involve test providers who are geographically close to the target population.

    1998-07-01

    A national audit of image quality and dose has been conducted across 267 mammography X ray sets in the UK Breast Screening Programme, repeating a previous survey in 1991. The main parameters were film density, film contrast, mean glandular dose to the standard breast (MGD) and image quality (IQ) measured with a TOR(MAM) test object. Film density has increased from a mean of 1.33 in 1991 to a mean of 1.61 in 1996 as a result of national guidelines. Over the same period the average MGD has increased from 1.28 to 1.36 mGy. Average film gradient ranged from 2.2 to 3.9 with a mean of 3.2. IQ ranged from 48 to 86 with a mean of 69. Causes of reduced IQ were low film densities, medium screens and older designs of mammography X ray set. Although film density and MGD were generally satisfactory, there appears to be room for further optimisation of film contrast and IQ. (author)

    2015-03-01

    Full Text Available α1-antitrypsin deficiency (AATD is a significantly under-recognised autosomal genetic disorder with <10% of affected individuals being clinically diagnosed. Moreover, rigorous genetic epidemiological data regarding AATD are lacking. The majority of findings come from the USA and Western Europe, and no information is available for many countries. To address this concern, an α1-antitrypsin (AAT laboratory was set up in 2009 at the National Institute of Tuberculosis and Lung Diseases (Warsaw, Poland. In 2010, an AATD screening programme targeting patients with respiratory disorders was initiated in Poland. This targeted survey has provided valuable information regarding AAT-deficient genotypes, clinical disease and levels of expertise at the physician level. After 4 years, almost 2500 patients with chronic obstructive pulmonary disorders have been screened and, in this cohort, ∼13% had AATD alleles. In these patients, the detection frequency for S and Z alleles was four times greater, and the frequency of homozygous PI*ZZ was 16 times greater than that of the general population. These results highlight the need to build awareness in the medical community, and the project is currently being extended to cover central Eastern Europe, with the creation of the Central Eastern European Alpha-1 Antitrypsin Network.

  9. Rubella serology by solid-phase radioimmunoassay: its potential for screening programmes

    International Nuclear Information System (INIS)

    Sera from 269 adult females who had experienced naturally acquired or vaccine-induced infection by rubella virus, including immune persons challenged intranasally with rubella vaccine (RA27/3) as well as sera from 100 patients attending antenatal clinics, were tested for rubella antibodies by the conventional haemagglutination inhibition tests (HAI), as well as a newly developed solid-phase radioimmunoassay (RIA) for rubella immunoglobulin G(IgG) antibodies. Following both naturally acquired and vaccine-induced infection, titres by RIA were approximately ten-fold higher than by HAI. The RIA test was particularly useful in assessing the true immune status of those with apparently low levels of HAI antibody and has the added advantage that pretreatment of sera to remove inhibitors of haemagglutination and red cell agglutinins is unnecessary. The RIA test has potential for the large-scale screening programmes which need to be carried out if the Department of Health and Social Security recommendation, that women attending antenatal and family planning clinics be screened for rubella antibodies, is to be effectively met.

    The randomized PLCO trial was designed to answer four primary questions: does screening for these cancers using often promoted tests reduce cancer-specific mortality? Nearly 155,000 men and women were allocated to screening or usual care arms in a 1:1 ratio under a centralized, secure randomization algorithm at ten competitively selected screening centers nationwide. Screened men received PSA blood tests and digital rectal examinations. Screened women received CA125 blood tests and trans-vaginal ultrasound. Both men and women in the screened arm received anterolateral view chest x-ray and 60 cm flexible sigmoidoscopy. Blood specimens were collected at each screening visit and buccal cell DNA was collected once from the usual care participants. Histology slides were collected for cancer cases. Participants completed a baseline questionnaire covering health and risk factors and a dietary questionnaire. Data collected on standardized machine-readable forms were scanned remotely at screening and laboratory sites utilizing PLCO dedicated, NCI provided and configured computer systems for quality checks, archiving, and analysis. Comprehensive quality assurance was implemented over recruitment, consenting, randomization, screening, data management, records keeping, patient-specific screening results reporting, follow-up, and data analysis. Performance and data quality were monitored on-site and remotely by data edits, site visits, and random record audits. Specially trained and certified professionals performed screening procedures and medical record abstracting. An independent committee of medical specialists reviewed and certified case-specific cause of death. Scientific leadership was provided by NCI Project Officers, PLCO principal investigators, external consultants, and an independent data and safety monitoring board. PMID:26238115

The group considered the following topics: cataracts, cardiovascular disease, cytogenetic markers, immunological effects, reproductive effects and children's health, psychological and mental effects, mortality due to the accident, and medical programmes and medical monitoring. The issues of potential cataracts at low doses as well as follow-up of liquidators disease incidence and mortality should be continued. Cytogenetic effects may be used to assess doses above 0.2 Gy but are unlikely to be useful at lower doses. There is no clear evidence of radiation-related adverse clinical effects on the immune system of the general public or on hereditary or reproductive outcomes (particularly congenital malformations). Lifespan reduction and death rates of the general public are higher in both contaminated and clean areas than in other countries as is infant mortality, but these are not felt to be radiation related. Although the major potential radiation-related health effect is felt to be the cancer risk, screening programmes are not felt to be useful when absorbed doses are in the range of tens of mGy or lower. Psychological effects are real and represent the biggest public health impact of the accident. These will need continuing attention for the foreseeable future. While the paper is focused entirely on potential adverse effects of the accident, one should recognize the efforts of the Governments of Belarus, the Russian Federation and Ukraine to protect and take care of the affected populations.

    Martin C S Wong

    Full Text Available PURPOSE: to evaluate the proportion of self-referred screening participants having various psychological barriers and the factors associated with these barriers. METHODS: A territory-wide bowel cancer screening centre sent an invitation via the media to all Hong Kong residents aged 50-70 years who were asymptomatic of CRC to join a free screening programme. Upon attendance they were requested to complete self-administered surveys on their perceived barriers of screening. Binary logistic regression analyses were used to evaluate the factors associated with these barriers. RESULTS: From 10,078 consecutive screening participants (mean age 57.5 years; female 56.4% completed the surveys between May 2008 to September 2012. There were high proportions who agreed or strongly agreed with the following barriers: financial difficulty (86.0%, limited service accessibility (58.2%, screening-induced bodily discomfort (55.2%, physical harm (44.4%, embarrassment (40.1%, apprehension (38.8% and time constraints (13.9%. From regression models, older participants (aged ≥ 56 were less likely to have these barriers (Adjusted odds ratio [AOR] ranged from 0.738 to 0.952 but they encountered more difficulties to access to screening services (AOR ranged from 1.141 to 1.371. Female subjects were more likely to encounter most of these barriers (AOR ranged from 1.188 to 2.179. Participants who were uncertain of the necessity of CRC screening for people aged ≥ 50 were more likely to report these barriers (AOR ranged from 1.151 to 1.671. CONCLUSION: The proportions of perceptual barriers of CRC screening were high among these participants. Those with these associated factors should receive more thorough explanation of the screening test procedures.

  15. Risk-benefit analysis for mass screening of breast cancer utilizing mammography as a screening test

    International Nuclear Information System (INIS)

    Incidence of breast cancers in Japanese women is increasing steadily. Mass screening of breast cancer was started in Japan under auspices of Adult Health Promotion Act of the Japanese Government from 1987. As the first screening method, the palpation of breasts is employed at present, but it is expected to be replaced by the mammography. In this report, the risk-benefit analysis is presented between risk of breast carcinogenesis due to radiation and benefit of mass screening of breast cancer. The benefit of mass screening is taken as the net elongation of average life expectancy of women due to survival from breast cancers. The risk of mammography is taken as the net loss of average life expectancy of women due to breast carcinogenesis. In the latter, the latency time and plateau period of radiation carcinogenesis were taken into consideration in the calculation. The results show that the ages at which the benefit and risk become equal are between 30 and 35 years old when dose equivalent of mammography is between 10 and 20 mSv, that are conventionally used. However, the critical age will be reduced to 20 years old if the dose equivalent becomes 1 mSv. Therefore, it is strongly recommended that a low dose mammographic system should be developed in order to achieve 1 mSv for the mass screening of breast cancer of Japanese women. In author's opinion, this is quite feasible by employing a new digital radiography with imaging plate. (author)

    In French Guiana, the age-standardized incidence rate of cervical cancer is four times higher than in France and the mortality rate 5.5 times higher. A survival study revealed that stage at diagnosis was the main factor influencing the prognosis, showing that early detection is crucial to increase cervical cancer survival. The present study aimed at evaluating the cervical cancer screening rate between 2006 and 2011 by age and for a 3-year period in French Guiana. All pap smears realised in French Guiana were analysed in two laboratories allowing exhaustive review of screening data. The screening rate was estimated at about 54% from 2006 to 2011, with a statistical difference between coastal and rural area (56.3% versus 18.7%). Although the methodological difference did not allow comparisons with metropolitan France, these results could be used to evaluate the impact of organised cervical cancer screening by the French Guiana Association for Organized Screening of Cancers which has been implemented in French Guiana since 2012.

    The literature on colorectal cancer (CRC screening is contradictory regarding the impact of weight status on CRC screening. This study was intended to determine if CRC screening rates among 2005 National Health Interview Survey (NHIS respondent racial/ethnic and gender subgroups were influenced by weight status. Methods. Univariable and multivariable logistic regression analyses were performed to determine if CRC screening use differed significantly among obese, overweight, and normal-weight individuals in race/ethnic and gender subgroups. Results. Multivariable analyses showed that CRC screening rates did not differ significantly for individuals within these subgroups who were obese or overweight as compared to their normal-weight peers. Conclusion. Weight status does not contribute to disparities in CRC screening in race/ethnicity and gender subgroups.

  18. Reducing inequities in colorectal cancer screening in North America

    2014-01-01

    Full Text Available Colorectal cancer (CRC is an important cause of mortality and morbidity in North America. Screening using a fecal occult blood test, flexible sigmoidoscopy, or colonoscopy reduces CRC mortality through the detection and treatment of precancerous polyps and early stage CRC. Although CRC screening participation has increased in recent years, large inequities still exist. Minorities, new immigrants, and those with lower levels of education or income are much less likely to be screened. This review provides an overview of the commonly used tests for CRC screening, disparities in CRC screening, and promising methods at the individual, provider, and system levels to reduce these disparities. Overall, to achieve high CRC participation rates and reduce the burden of CRC in the population, a multi-faceted approach that uses strategies at all levels to reduce CRC screening disparities is urgently required.

    Similar to other Middle Eastern countries, breast cancer is the most common cancer among women in Qatar with increasing incidence and mortality rates. High mortality rates of breast cancer in the Middle Eastern countries are primarily due to delayed diagnosis of the disease. Thus screening and early detection of breast cancer are important in reducing cancer morbidity and mortality. With the aim of updating knowledge on existing interventions and developing effective intervention programs to promote breast cancer screening in Arabic populations in Qatar, this review addresses the question: What interventions are effective in increasing breast cancer knowledge and breast cancer screening rates in Arabic populations in Arabic countries and North America? Systematic literature review was performed to answer the proposed question. As the result of the search, six research studies were identified and appraised. From the findings, we infer several insights: (a) a language-appropriate and culturally sensitive educational program is the most important component of a successful intervention regardless of the study setting, (b) multi-level interventions that target both women, men, health care professionals, and/or larger health care system are more likely to be successful than single educational interventions or public awareness campaigns, and (c) more vigorous, personal and cognitive interventions that address psychosocial factors are likely to be more effective than less personal and informative interventions. This review has important implications for health care providers, intervention planners, and researchers. PMID:23975014

    The study examines the role of patient colorectal cancer (CRC) screening test preference and CRC screening uptake in an insured, urban minority population. Study subjects were enrolled in a randomized controlled trial to promote CRC screening. The interventions were educational, with an emphasis on colonoscopy screening. Subjects were 50+ years of age, fully insured for CRC screening, and out of compliance with current CRC screening recommendations. This paper includes those who answered a question about CRC screening test preference and indicated that they intended to receive such a test in the coming year (n = 453). CRC screening uptake was ascertained from medical claims data. Regardless of test preference, few received CRC screening (22.3 %). Those preferring the home stool test (HST) were less likely to get tested than those preferring a colonoscopy (16.6 vs 29.9 %, χ(2) = 9.9, p = .002). Preference for HST was more strongly associated with beliefs about colonoscopy than with knowledge about colonoscopy. In the context of an RCT emphasizing colonoscopy screening for CRC, patients expressing a preference for HST are at heightened risk of remaining unscreened. Colonoscopy should be recommended as the preferred CRC test, but HSTs should be accessible and encouraged for patients who are averse to colonoscopy.Clinical trials.gov: Identifier: NCT02392143.

    Pancreatic cancer exhibits an extraordinarily high level of resistance to almost any kind of systemic therapy evaluated in clinical trials so far. Therefore, the identification of novel therapeutic targets is urgently required. High-throughput screens have emerged as an important tool to identify putative targets for diagnosis and therapy in an unbiased manner. More than a decade ago, microarray technology was introduced to identify differentially expressed genes in pancreatic cancer as compared to normal pancreas, chronic pancreatitis and other cancer types located in close proximity to the pancreas. In addition, proteomic screens have facilitated the identification of differentially secreted proteins in body fluids of pancreatic cancer patients, serving as possible biomarkers. Recently, RNA interference-based loss-of-function screens have been used to identify functionally relevant genes, whose knock-down has impact on pancreatic cancer cell viability, thereby representing potential new targets for therapeutic intervention. This review summarizes recent results of transcriptional, proteomic and functional screens in pancreatic cancer and discusses potentials and limitations of the respective technologies as well as their impact on future therapeutic developments.

    Oral cavity and oropharyngeal cancer (oral cancer) is a deadly disease that is increasing in incidence. Worldwide 5-year survival is only 50% due to delayed intervention with more than half of the diagnoses at stage III and IV, whereas earlier detection (stage I and II) yields survival rates up to 80% to 90%. Salivary soluble CD44 (CD44), a tumor-initiating marker, and total protein levels may facilitate oral cancer risk assessment and early intervention. This study used a hospital-based design with 150 cases and 150 frequency-matched controls to determine whether CD44 and total protein levels in oral rinses were associated with oral cancer independent of age, gender, race, ethnicity, tobacco and alcohol use, and socioeconomic status (SES). High-risk subjects receiving oral cancer prevention interventions as part of a community-based program (n = 150) were followed over 1 year to determine marker specificity and variation. CD44 ≥5.33 ng/mL was highly associated with case status [adjusted OR 14.489; 95% confidence interval (CI), 5.973-35.145; P cancer. In contrast, specificity in the high-risk community was 74% and reached 95% after annual retesting. Simple and inexpensive salivary CD44 and total protein measurements may help identify individuals at heightened risk for oral cancer from the millions who partake in risky behaviors.

    Treatments for breast cancer often include interventions related to psychosocial issues such as negative body image, loss of femininity, and low self-esteem. We identified the psychological effects of a cosmetics education programme in patients with breast cancer. Cosmetic programme is a specific care designed to help patients handle appearance-related side effects. Thirty-one women with breast cancer at a university hospital in South Korea who received a cosmetics education programme were compared with 29 subjects in a control group who received the treatment as usual. Psychological factors including distress, self-esteem, and sexual functioning were assessed three times (before and after the programme, and at the 1-month follow-up). After the programme, patients in the treatment group were significantly less likely than those in the control group to rely on distress (P = 0.038) and avoidance coping (P self-esteem. The mean scores in the treatment group for sexual functioning were higher than those in the control group after the treatment. Our results suggest the potential usefulness of a brief cosmetics education programme for reducing distress and reliance on negative coping strategies. Implementing a cosmetics programme for patients with breast cancer may encourage patients to control negative psychological factors. PMID:25651297

    Cervical cancer is recognized as tobacco-related malignancy. HPV vaccination and introducing screening protocols were found as the best way to decrease cervical cancer related mortality. Besides the cytological screening programs of the uterine cervix smear, nowadays co-factors of carcinogenesis are taken into consideration, also. The aim of our study was to analyse data included in questionnaire of 310 women who underwent cytological examination wi thin cervical cancer screening program in our Department in 2011. There were no differences found between studied groups on rate of oral contraceptive or hormonal therapy use, as well as age and tobacco smoking. However, taking into account education and smoking, there was a significant correlation observed. Patients with higher education level smoked less often. The special attention should be paid to promote smoking cessation in the group of women who finished education on elementary level. PMID:23421059

    The Health Council of the Netherlands recently issued a report advising adding 14 new disorders to the current neonatal screening programme: 11 metabolic conditions, severe combined immunodeficiency disease, beta-thalassaemia major and HbH disease. This recommendation was made because of the availability of new tests and treatments. The new criteria of availability and accessibility of treatment became relevant following discussions on reimbursement of enzyme replacement therapy for Pompe's disease. The potential for alternative or complementary measures for prevention are discussed, such as preconception and prenatal carrier screening. This report advises against reporting carrier information following newborn screening: advice that is not in line with earlier Health Council advice. A further recommendation is that newborn screening for untreatable conditions is not indicated now. Screening for untreatable conditions may not be the responsibility of national public health agencies, but alternative stakeholders have not been considered in the report. PMID:25970680

    Full Text Available Background. Alaska Native people have nearly twice the rate of colorectal cancer (CRC incidence and mortality as the US White population. Objective. Building upon storytelling as a culturally respectful way to share information among Alaska Native people, a 25-minute telenovela-style movie, What's the Big Deal?, was developed to increase CRC screening awareness and knowledge, role-model CRC conversations, and support wellness choices. Design. Alaska Native cultural values of family, community, storytelling, and humor were woven into seven, 3–4 minute movie vignettes. Written post-movie viewing evaluations completed by 71.3% of viewers (305/428 were collected at several venues, including the premiere of the movie in the urban city of Anchorage at a local movie theater, seven rural Alaska community movie nights, and five cancer education trainings with Community Health Workers. Paper and pencil evaluations included check box and open-ended questions to learn participants' response to a telenovela-style movie. Results. On written-post movie viewing evaluations, viewers reported an increase in CRC knowledge and comfort with talking about recommended CRC screening exams. Notably, 81.6% of respondents (249/305 wrote positive intent to change behavior. Multiple responses included: 65% talking with family and friends about colon screening (162, 24% talking with their provider about colon screening (59, 31% having a colon screening (76, and 44% increasing physical activity (110. Conclusions. Written evaluations revealed the telenovela genre to be an innovative way to communicate colorectal cancer health messages with Alaska Native, American Indian, and Caucasian people both in an urban and rural setting to empower conversations and action related to colorectal cancer screening. Telenovela is a promising health communication tool to shift community norms by generating enthusiasm and conversations about the importance of having recommended colorectal

    Answer questions and earn CME/CNE People with mental illness die decades earlier in the United States compared with the general population. Most of this disparity is related to preventable and treatable chronic conditions, with many studies finding cancer as the second leading cause of death. Individual lifestyle factors, such as smoking or limited adherence to treatment, are often cited as highly significant issues in shaping risk among persons with mental illness. However, many contextual or systems-level factors exacerbate these individual factors and may fundamentally drive health disparities among people with mental illness. The authors conducted an integrative review to summarize the empirical literature on cancer prevention, screening, and treatment for people with mental illness. Although multiple interventions are being developed and tested to address tobacco dependence and obesity in these populations, the evidence for effectiveness is quite limited, and essentially all prevention interventions focus at the individual level. This review identified only one published article describing evidence-based interventions to promote cancer screening and improve cancer treatment in people with mental illness. On the basis of a literature review and the experience and expertise of the authors, each section in this article concludes with suggestions at the individual, interpersonal, organizational, community, and policy levels that may improve cancer prevention, screening, and treatment in people with mental illness.

    Abstract Objective To investigate overall colorectal cancer (CRC) screening rates, patterns in the use of types of CRC screening, and sociodemographic characteristics associated with CRC screening; and to gain insight into physicians’ perceptions about and use of fecal occult blood testing [FOBT] and colonoscopy for patients at average risk of CRC. Design Mixed-methods study using cross-sectional administrative data on patient sociodemographic characteristics and semistructured telephone interviews with physicians. Setting Toronto, Ont. Participants Patients aged 50 to 74 years and physicians in family health teams in the Toronto Central Local Health Integration Network. Main outcome measures Rates of CRC screening by type; sociodemographic characteristics associated with CRC screening; thematic analysis using constant comparative method for semistructured interviews. Main findings Ontario administrative data on CRC screening showed lower overall screening rates among those who were younger, male patients, those who had lower income, and recent immigrants. Colonoscopy rates were especially low among those with lower income and those who were recent immigrants. Semistructured interviews revealed that physician opinions about CRC screening for average-risk patients were divided: one group of physicians accepted the evidence and recommendations for FOBT and the other group of physicians strongly supported colonoscopy for these patients, believing that the FOBT was an inferior screening method. Physicians identified specialist recommendations and patient expectations as factors that influenced their decisions regarding CRC screening type. Conclusion There was considerable variation in CRC screening by sociodemographic characteristics. A key theme that emerged from the interviews was that physicians were divided in their preference for FOBT or colonoscopy; factors that influenced physician preference included the health care system, recommendations by other

    Growing evidence suggests health disparities exist in services for individuals with mental disorders served by the public mental health system. The current study assessed the use of cancer screening services among New Jersey residents in publicly funded mental health programs. Self-administered written surveys were completed by 148 adults using peer-led community wellness centers throughout New Jersey. Information was collected on (a) the use of breast, cervical, and colorectal cancer screening services; (b) barriers to receiving preventive services; and (c) perceptions of overall health. More males than females participated in the study, with equal participation among White and African American individuals. Schizophrenia spectrum disorders were the most common self-reported psychiatric condition. Colorectal cancers had lower screening levels compared to those of the general population. Physicians not advising patients to complete tests emerged as a main cause of low screening rates. Wellness initiatives designed by peers collaborating with health care providers may improve adherence to preventive cancer screening measures.

    Automation of the Pap-smear cervical screening method is highly desirable as it relieves tedium for the human operators, reduces cost and should increase accuracy and provide repeatability. We present here the design for a high-throughput optoelectronic system which forms the first stage of a two stage system to automate pap-smear screening. We use a mathematical morphological technique called the hit-or-miss transform to identify the suspicious areas on a pap-smear slide. This algorithm is implemented using a VanderLugt architecture and a time-sequential ANDing smart pixel array.

    Colorectal cancer (CRC) is now common in Thailand with an increase in incidence over time. Health authorities are planning to implement a nationwide CRC screening program using fecal immunochemical test (FIT) as a primary screening tool. This study aimed to estimate preferences and acceptance of FIT and colonoscopy, explore factors influencing the acceptance, and investigate reasons behind choosing and rejecting to screen before the program was implemented. Patients aged 50-69, visiting the primary care unit during the study period, were invited to join this study. Patients with a history of cancer or past CRC screening were excluded. Face-to-face interviews were conducted. Subjects were informed about CRC and the screening tests: FIT and colonoscopy. Then, they were asked for their opinions regarding the screening. The total number of subjects was 437 (86.7% response rate). Fifty-eight percent were females. The median age was 58 years. FIT was accepted by 74.1% of subjects compared to 55.6% for colonoscopy. The acceptance of colonoscopy was associated with perceived susceptibility to CRC and family history of cancer. No symptoms, unwilling to screen, healthy, too busy and anxious about diagnosis were reasons for refusing to screen. FIT was preferred for its simplicity and non-invasiveness compared with colonoscopy. Those rejecting FIT expressed a strong preference for colonoscopy. Subjects chose colonoscopy because of its accuracy; it was refused for the process and complications. If the screening program is implemented for the entire target population in Thailand, we estimate that 106,546 will have a positive FIT, between 8,618 and 12,749 identified with advanced adenoma and between 2,645 and 3,912 identified with CRC in the first round of the program.

    Clinical guidelines continue to move away from routine prostate specific antigen screening (PSA), once a widespread medical practice. A curious difference exists between early prostate cancer and early breast cancer. While randomized trials of therapy in early breast cancer continue to show overall survival benefit, this is not the case in prostate cancer, where prostatectomy was no better than observation in a recent trial, and where early androgen deprivation is no better than late androgen deprivation. Here, I make the case that prostate cancer screening contributes so greatly to over diagnosis that even treatment trials yield null results due to contamination with non-life threatening disease.

    Higher breast density is associated with a greater chance of developing breast cancer. Additionally, it is well known that higher mammographic breast density is associated with increased difficulty in accurately identifying breast cancer. However, comparatively little is known of the reliability of breast density judgements. All UK breast screeners (primarily radiologists and technologists) annually participate in the PERFORMS self-assessment scheme where they make several judgements about series of challenging recent screening cases of known outcomes. As part of this process, for each case, they provide a radiological assessment of the likelihood of cancer on a confidence scale, alongside an assessment of case density using a three point scale. Analysis of the data from two years of the scheme found that the degree of agreement on case density was significantly greater than no agreement (p < .001). However, only a moderate degree of inter-rater reliability was exhibited (κ = .44) with significant differences between the occupational groups. The reasons for differences between the occupational groups and the relationship between agreement on density rating and case reading ability are explored.

  5. New Molecular Tools for Efficient Screening of Cervical Cancer

    2001-01-01

    Full Text Available Cytological screening using the Pap-smear led to a remarkable reduction of the mortality of cervical cancer. However, due to subjective test criteria it is hampered by poor inter- and intra-observer agreement. More reproducible assays are expected to improve the current screening and avoid unnecessary medical intervention and psychological distress for the affected women. Cervical cancer arises as consequence of persistent high risk papillomavirus (HR-HPV infections. Expression of two viral oncogenes, E6 and E7, in epithelial stem cells is required to initiate and maintain cervical carcinogenesis and results in significant overexpression of the cellular p16INK4a protein. Since this protein is not expressed in normal cervical squamous epithelia, screening for p16INK4a over-expressing cells allows to specifically identify dysplastic lesions, and significantly reduces the inter-observer disagreement of the conventional cytological or histological tests. Progression of preneoplastic lesions to invasive cancers is associated with extensive recombination of viral and cellular genomes which can be monitored by detection of papillomavirus oncogene transcripts (APOT assay derived from integrated viral genome copies. Detection of integrated type oncogene transcripts points to far advanced dysplasia or invasive cancers and thus represents a progression marker for cervical lesions. These new assays discussed here will help to improve current limitations in cervical cancer screening, diagnosis, and therapy control.

    AIM: To provide an update on colorectal cancer (CRC) screening programmes in non-European Union (EU)-28 Council of Europe member states as of December 2015. METHODS: The mission of the Council of Europe is to protect and promote human rights in its 47 member countries. Its 19 non-EU member states are Albania, Andorra, Armenia, Azerbaijan, Bosnia and Herzegovina, Republika Srpska, Georgia, Iceland, Liechtenstein, Republic of Moldova, Monaco, Montenegro, Norway, Russian Federation, San Marino, Serbia, Switzerland, FYR of Macedonia, Turkey, and Ukraine (EU-19). The main data source were GLOBOCAN, IARC, WHO, EUCAN, NORDCAN, ENCR, volume X of the CI5, the ministerial and Public Health Agency websites of the individual countries, PubMed, EMBASE, registries of some websites and the www.cochranelibrary.com, Scopus, www.clinicaltrials.gov, www.clinicaltrialsregister.eu, Research gate, Google and data extracted from screening programme results. RESULTS: Our results show that epidemiological data quality varies broadly between EU-28 and EU-19 countries. In terms of incidence, only 30% of EU-19 countries rank high in data quality as opposed to 86% of EU-28 states. The same applies to mortality data, since 52% of EU-19 countries as against all EU-28 countries are found in the high ranks. Assessment of the method of collection of incidence data showed that only 32% of EU-19 countries are found in the top three quality classes as against 89% of EU-28 countries. For the mortality data, 63% of EU-19 countries are found in the highest ranks as opposed to all EU-28 member states. Interestingly, comparison of neighbouring countries offering regional screening shows, for instance, that incidence and mortality rates are respectively 38.9 and 13.0 in Norway and 29.2 and 10.9 in Sweden, whereas in Finland, where a national organised programme is available, they are respectively 23.5 and 9.3. CONCLUSION: Cancer screening should be viewed as a key health care tool, also because investing in

    International Nuclear Information System (INIS)

    On the 26th May 2009 the World Health Organization (WHO) and the International Atomic Energy Agency (IAEA) announced the launch of a Joint Programme on Cancer Control, aimed at strengthening and accelerating efforts to fight cancer in the developing world. WHO and the IAEA have complementary mandates when it comes to fighting cancer. WHO is the leader amongst the UN family of organizations in terms of health improvement for people, particularly in low- and middle-income countries, while the IAEA's expertise in radiation medicine is a vital element of cancer diagnosis and treatment. The Joint Programme will provide the framework for the two Organizations to dovetail their work, building on their areas of expertise to create a more coordinated and robust approach to combating cancer in poor countries. In practical terms, this will mean working with Member States to integrate diagnostic and treatment-related activities into cancer control plans of the country based on WHO cancer control guidelines and strategies in each region. Efforts in the joint programme are focusing on six PACT Model Demonstration Sites (PMDS) in Albania, Nicaragua, Sri Lanka, Tanzania, Viet Nam and Yemen. They will also respond to requests for cancer control assessment and programme development assistance in low- and middle-income countries

    Objectives To assess the performance of a 5-type human papillomavirus (HPV) messenger RNA (mRNA) test in primary screening within the framework of the Norwegian population-based screening programme. Design Nationwide register-based cohort study. Setting In 2003–2004, general practitioners and gynaecologists recruited 18 852 women for participation in a primary screening study with a 5-type HPV mRNA test. Participants After excluding women with a history of abnormal smears and with cervical intraepithelial neoplasia grade 2 (CIN2+) before or until 3 months after screening, 11 220 women aged 25–69 years were eligible for study participation. The Norwegian Cancer Registry completed follow-up of CIN2+ through 31 December 2009. Interventions Follow-up according to the algorithm for cytology outcomes in the population-based Norwegian Cervical Cancer Screening Programme. Main outcome measures We estimated cumulative incidence of CIN grade 3 or worse (CIN3+) 72 months after the 5-type HPV mRNA test. Results 3.6% of the women were HPV mRNA-positive at baseline. The overall cumulative rate of CIN3+ was 1.3% (95% CI 1.1% to 1.5%) through 72 months of follow-up, 2.3% for women aged 25–33 years (n=3277) and 0.9% for women aged 34–69 years (n=7943). Cumulative CIN3+ rates by baseline status for HPV mRNA-positive and mRNA-negative women aged 25–33 years were 22.2% (95% CI 14.5% to 29.8%) and 0.9% (95% CI 0.4% to 1.4%), respectively, and 16.6% (95% CI 10.7% to 22.5%) and 0.5% (95% CI 0.4% to 0.7%), respectively, in women aged 34–69 years. Conclusions The present cumulative incidence of CIN3+ is similar to rates reported in screening studies via HPV DNA tests. Owing to differences in biological rationale and test characteristics, there is a trade-off between sensitivity and specificity that must be balanced when decisions on HPV tests in primary screening are taken. HPV mRNA testing may be used as primary screening for women aged 25–33 years and

    Full Text Available Protocols for activity aiming at early diagnosis and treatment of inherited breast or breast-ovarian cancer have been reported. Available reports on outcome of such programmes are considered here. It is concluded that the ongoing activities should continue with minor modifications. Direct evidence of a survival benefit from breast and ovarian screening is not yet available. On the basis of expert opinion and preliminary results from intervention programmes indicating good detection rates for early breast cancers and 5-year survival concordant with early diagnosis, we propose that women at high risk for inherited breast cancer be offered genetic counselling, education in ‘breast awareness’ and annual mammography and clinical expert examination from around 30 years of age. Mammography every second year may be sufficient from 60 years on. BRCA1 mutation carriers may benefit from more frequent examinations and cancer risk may be reduced by oophorectomy before 40–50 years of age. We strongly advocate that all activities should be organized as multicentre studies subjected to continuous evaluation to measure the effects of the interventions on long-term mortality, to match management options more precisely to individual risks and to prepare the ground for studies on chemoprevention.

    An optoelectronic system has been designed to pre-screen pap-smear slides and detect the suspicious cells using the hit/miss transform. Computer simulation of the algorithm tested on 184 pap-smear images detected 95% of the suspicious region as suspect while tagging just 5% of the normal regions as suspect. An optoelectronic implementation of the hit/miss transform using a 4f Vander-Lugt correlator architecture is proposed and demonstrated with experimental results.

    13% over the age range 35-79 years. This error range can be reduced to 1% when compressed breast thickness and age are used to estimate breast glandularity. At low breast thickness, little difference is found between composition dependent MGD-per-film estimates for women with augmented breasts and their non augmented counterparts. At high breast thickness however, the MGD's per film received by women with breast prostheses are considerably lower. In general, the BRR relating to the NHSBSP is favourable, even for subgroups of women who are thought to be at high risk or to obtain low benefit from the examination. The overall breast cancer mortality reduction for the NHSBSP at steady state was found to be in agreement with the Health of the Nation target of 25% in the age range 55-69 years. The use of mammography as a screening modality must be justified by comparison of the benefits and risks associated with the technique.

    Currently, there is a lack of evidence evaluating the psychological impact of cancer-related risk perception and worry in individuals at high risk for gastric cancer. We examined the relationships between perceived risk, cancer worry and screening behaviors among first-degree relatives (FDRs) of patients with familial gastric cancer. FDRs of patients diagnosed with familial gastric cancer with a non-informative genetic analysis were identified and contacted. Participants completed a telephone interview that assessed socio-demographic information, cancer risk perception, cancer worry, impact of worry on daily functioning, and screening behaviors. Twenty-five FDRs completed the telephone interview. Participants reported high levels of comparative and absolute cancer risk perception, with an average perceived lifetime risk of 54 %. On the other hand, cancer-related worry scores were low, with a significant minority (12 %) experiencing high levels of worry. Study participants exhibited high levels of confidence (median = 70 %) in the effectiveness of screening at detecting a curable cancer. Participants that had undergone screening in the past showed significantly lower levels of cancer-related worry compared to those that had never undergone screening. In conclusion, individuals at high-risk for gastric cancer perceived a very high personal risk of cancer, but reported low levels of cancer worry. This paradoxical result may be attributed to participants' high levels of confidence in the effectiveness of screening. These findings highlight the importance for clinicians to discuss realistic risk appraisals and expectations towards screening with unaffected members of families at risk for gastric cancer, in an effort to help mitigate anxiety and help with coping.

    2014-11-01

    Organised screening programmes have been remarkably successful in reducing incidence and mortality from cervical cancer, while opportunistic screening varies in its effectiveness. Experts recommend that cervical screening or HPV testing be carried out only in the context of an organised programme. We sought to answer the following study questions: What does it mean for a cervical screening programme to be organised? Is there a place for opportunistic screening (in an organised programme)? We reviewed 154 peer-reviewed papers on organised and opportunistic approaches to cervical screening published between 1970 and 2014 to understand how the term 'organised' is used, formally and in practice. We found that despite broad recognition of a prescriptive definition of organisation, in practice the meaning of organisation is much less clear. Our review revealed descriptions of organised programmes that differ significantly from prescribed norms and from each other, and a variety of ways that opportunistic and organised programmes intersect. We describe the breadth of the variation in cervical cancer screening programmes and examine the relationships and overlaps between organised and opportunistic screening. Implications emerging from the review include the need to better understand the breadth of organisation in practice, the drivers and impacts of opportunistic screening and the impact of opportunistic screening on population programme outcomes. Appreciation of the complexity of cervical screening programmes will benefit both screeners and women as programmes are changed to reflect a partially vaccinated population, new evidence and new technologies.

  3. Cervical cancer screening in Belgium and overscreening of adolescents.

    Van Kerrebroeck, Helena; Makar, Amin

    2016-03-01

    There has been a marked decrease in the incidence of cervical cancer thanks to cytological screening with the Pap smear test. In Belgium, this screening is rather opportunistic. Over 39% of Belgian women between 25 and 64 years of age are never or only rarely screened by cytological tests. Moreover, there is an excess use of Pap smears because of women who rely on their yearly cervical smear and because many Pap smears are obtained from women beyond the target age range of 25 to 64 years. Sexually active adolescents are increasingly being recognized as a population distinct from adult women. They are at a high risk of acquiring the human papillomavirus (HPV), but most infections and cervical intraepithelial lesions caused by HPV are efficiently cleared by the immune system. We present a description of cervical cancer screening in Belgium using the database of the National Health Insurance Institute (RIZIV/INAMI) and the Belgian Health Care Knowledge Centre (KCE). We describe why elimination of Pap testing in the adolescent population reduces costs and harms without increasing cervical cancer rates. Expectant management, education on the risk factors for cervical cancer and HPV persistence, and HPV vaccination are very important in adolescents and young adults. PMID:25812038

    This article provides an overview of the main controversies in a number of key areas of breast cancer management. Relevant studies that have contributed to guide the treatment of this heterogeneous disease in the field of breast screening, surgery, chemotherapy and radiotherapy are highlighted. Mammography and ultrasound are the main methods of breast screening. MRI and tomosynthesis are emerging as new screening tools for a selected group of breast cancer patients. From a surgical perspective, oncoplastic techniques and neoadjuvant chemotherapy are improving cosmetic results in breast-conserving surgery. For high-risk patients, controversies still remain regarding prophylactic mastectomies. Finally, the appropriate management of the axilla continues evolving with the increasing role of radiotherapy as an alternative treatment to axillary dissection. PMID:26689336

    Radiology administrators must use innovative strategies around clinical collaboration and marketing to ensure that patients access the service in sufficient numbers. Radiology Associates of South Florida in collaboration with Baptist Health South Florida have developed a successful lung cancer screening program. The biggest factors in their success have been the affordability of their service and the quality of the program. Like mammography, lung cancer screening programs serve as an entry point to other services that generate revenue for the hospital. Patients may require further evaluation in the form of more imaging or surgical services for biopsy. Part 1 provided background and laid out fundamentals for starting a program. Part 2 focuses on building patient volume, marketing, and issues related to patient management after the screen is performed. PMID:26314180

Methods: This survey was a descriptive study in which 400 women participated in health and treatment centers in Yazd. Sampling method was done in two simple and random stages. Data was collected by inventory and questionnaire . Then data were analyzed by SPSS soft ware . Results: Findings showed that 80% of them never refereed to a health provider for clinical breast exam (C B E and only 3% of them did regularly C B E . 46% of them had never done pap smear and only 14.5 % of them did regularly pap smear. The findings showed that major motivators were as follow: advice of health’s personnel , using of contraceptive methods , and awareness of media. Also the major barriers were as follow : Not having knowledge of these exams , not having knowledge of the existence of these centers of education and practice , not having precious health problems , fear of examination , Embarrassment of examination and health providers not to teach them . to consider the most important barriers were propounded which showed that health education role to eliminate barriers for referring women for screening . Discussion: Based on the results of this sample , screening was the least expected . considering barriers and motivators observed it was revealed that health education was required for prevention of common women’s cancers.

    Highlights: • The addition of supplemental US to mammography depicted additional 5.0 cancers per 1000 postoperative women. • Positive biopsy rate of mammography-detected lesions was 66.7% (4 of 6) and that of US-detected lesions was 40.0% (6 of 15). • US can be helpful to detect mammographically occult breast cancer in the contralateral breast in women with previous history of cancer and dense breast. - Abstract: Objective: To determine whether supplemental screening ultrasound (US) to mammography could improve cancer detection rate of the contralateral breast in patients with a personal history of breast cancer and dense breasts. Materials and methods: During a one-year study period, 1314 screening patients with a personal history of breast cancer and dense breasts simultaneously underwent mammography and breast US. BI-RADS categories were given for mammography or US-detected lesions in the contralateral breast. The reference standard was histology and/or 1-year imaging follow-up, and the cancer rate according to BI-RADS categories and cancer detection rate and positive biopsy rate according to detection modality were analyzed. Results: Of 1314 patients, 84 patients (6.4%) were categorized as category 3 with one interval cancer and one cancer which was upgraded to category 4A after 6-month follow-up US (2.5% cancer rate, 95% CIs 1.5–9.1%). Fifteen patients (1.1%) had category 4A or 4B lesions in the contralateral breast. Four lesions were detected on mammography (two lesions were also visible on US) and 11 lesions were detected on US and 5 cancers were confirmed (33.3%, 95% CIs 15.0–58.5%). Six patients (0.5%) had category 4C lesions, 2 detected on mammography and 4 on US and 4 cancers were confirmed (66.7%, 95% CIs 29.6–90.8%). No lesions were categorized as category 5 in the contralateral breast. Cancer detection rate by mammography was 3.3 per 1000 patients and that by US was 5.0 per 1000 patients, therefore overall cancer detection rate by

    Development of a workshop on skin cancer screening should begin with physicians who are able to best diagnose and treat skin cancer, that is, dermatologists who are board certified or board eligible. Local societies should then be involved as well as organizations that can offer ancillary help such as screening, clinics' location and assisting with personnel financial aid, and exposure to the public, such as advertising. Support groups then become essential to a good screening. The help of the American Cancer Society, local churches, clubs, and others is beneficial. The organization should have a central organizing body that sets the dates and locations for the clinics and that helps get supplies, such as tables, screens for privacy, and literature. Volunteers can help with sign-in and sign-out sheets for the screening and can act as traffic directors and assist the physicians. Media exposure then becomes important. A TV or radio show can get the public's attention, for example, by releasing the latest data on skin cancer or by presenting a solar meter project showing the local risk of ultraviolet radiation. The workshop itself should begin on time. Additionally, a cutoff time is also needed. In the final stage, the forms should be processed and a follow-up evaluation should be done on the number of patients seen, precancerous and cancerous lesions found, and the potential for future functions. Popular ancillary aids are good literature on the subjects discussed, and samples of sunscreens (SPF 15 or better) that are donated by pharmaceutical companies. PMID:7804998

  5. Molecular profiles of screen detected vs. symptomatic breast cancer and their impact on survival: results from a clinical series

    International Nuclear Information System (INIS)

    Stage shift is widely considered a major determinant of the survival benefit conferred by breast cancer screening. However, factors and mechanisms underlying such a prognostic advantage need further clarification. We sought to compare the molecular characteristics of screen detected vs. symptomatic breast cancers and assess whether differences in tumour biology might translate into survival benefit. In a clinical series of 448 women with operable breast cancer, the Kaplan-Meier method and the log-rank test were used to estimate the likelihood of cancer recurrence and death. The Cox proportional hazard model was used for the multivariate analyses including mode of detection, age at diagnosis, tumour size, and lymph node status. These same models were applied to subgroups defined by molecular subtypes. Screen detected breast cancers tended to show more favourable clinicopathological features and survival outcomes compared to symptomatic cancers. The luminal A subtype was more common in women with mammography detected tumours than in symptomatic patients (68.5 vs. 59.0%, p=0.04). Data analysis across categories of molecular subtypes revealed significantly longer disease free and overall survival for screen detected cancers with a luminal A subtype only (p=0.01 and 0.02, respectively). For women with a luminal A subtype, the independent prognostic role of mode of detection on recurrence was confirmed in Cox proportional hazard models (p=0.03). An independent role of modality of detection on survival was also suggested (p=0.05). Molecular subtypes did not substantially explain the differences in survival outcomes between screened and symptomatic patients. However, our results suggest that molecular profiles might play a role in interpreting such differences at least partially. Further studies are warranted to reinterpret the efficacy of screening programmes in the light of tumour biology

    The aim of this article was to discuss the recommendation of mammogram screening for breast cancer and its technical basis. The first part discusses criteria for the decision, which should be consistent with high-quality scientific evidence. The second part discusses over-diagnosis (the greatest harm of screening) and its meaning in questioning the natural history of disease model. The third part summarizes studies on the efficacy, effectiveness, and harms of screening, showing that the latter (especially over-diagnosis and false-positives) are significant, shedding doubt on the balance between harms and benefits. In conclusion, the recommendation of mammogram screening at any age should be reconsidered by Brazilian health authorities. PMID:27253456

    Directory of Open Access Journals (Sweden)

    von der Schulenburg, Johann-Matthias

    2007-08-01

    Full Text Available Introduction: With 3.2% of all cancer cases in 2002, cervical carcinoma is the tenth most common cancer in Germany and causes 1.8% of all cancer deaths in women in Germany. To date diagnosis in Germany solely has been based on cervical cytology which has been criticised due to its low sensitivity and consequently high rate of false negative results. Objectives: How does colposcopy compare to cytological tests in terms of sensitivity and specificity, and what may be the effects of changes in screening for cervical carcinoma in Germany? Is there health economic evidence that may foster an inclusion of colposcopy into national screening programms? Methods: A systematic literature review was performed, including studies that compared colposcopy to cervical cytology in terms of sensitivity and specificity. In addition, a systematic review of the relevant health economic literature was performed to analyse cost-effectiveness issues relevant to the German setting. Results: A total of four studies fulfilled the inclusion criteria, of which only two were of high methodologic quality. In all studies, the sensitivity of colposcopy was lower than that of cytology. In three studies the specificity of colposcopy was lower than that of cytology, in one study specificity of colposcopy and cytology was similar. No health economic data suggesting positive effects of adding colposcopy in primary screening could be identified. Discussion: Only few studies have compared the test criteria of colposcopy with those of cytology for screening in cervical cancer. In all studies, sensitivity of colposcopy was even lower than the sensitivity of cytology, which has been critisized because of its low sensitivity. Conclusion: Based on the present data, an inclusion of colposcopy in primary cervical cancer screening programmes can not be recommended.

    AIM:To investigate barriers to colorectal cancer (CRC) screening in a community population. METHODS:We conducted a community-based case-control study in an urban Chinese population by questionnaire. Cases were selected from those completing both a fecal occult blood test (FOBT) case and colonoscopy in a CRC screening program in 2004. Control groups were matched by gender, age group and community. Control 1 included those having a positive FOBT but refusing a colonoscopy. Control 2 included those who refused both an FOBT and colonoscopy. RESULTS:The impact of occupation on willingness to attend a colorectal screening program differed by gender. P for heterogeneity was 0.009 for case vs control group 1, 0.01 for case versus control group 2, and 0.80 for control group 1 vs 2. Poor awareness of CRC and its screening program, characteristics of screening tests, and lack of time affected the screening rate. Financial support, fear of pain and bowel preparation were barriers to a colonoscopy as a screening test. Eighty-two percent of control group 1 and 87.1% of control group 2 were willing attend if the colonoscopy was free, but only 56.3% and 53.1%,respectively, if it was self-paid. Multivariate odds ratios for case vs control group 1 were 0.10 among those unwilling to attend a free colonoscopy and 0.50 among those unwilling to attend a self-paid colonoscopy. CONCLUSION:Raising the public awareness of CRC and its screening, integrating CRC screening into the health care system, and using a painless colonoscopy would increase its screening rate.

    2007-01-01

    Clifton Leaf, in his article "Why We're Losing the War on Cancer," presents criticisms of past research approaches and the small impact of this research thus far on producing cures or substantially extending the life of many cancer patients. It is true that gains in long-term survival for people with advanced cancers have been modest, hindered in part by the heterogeneity of tumors, which allows the cancers to persist using alternate molecular pathways and so evade many cancer therapeutics. In contrast, clinical trials have demonstrated that it is possible to reduce the incidence or improve cancer survival through prevention and early detection. Strides have been made in preventing or detecting early the four deadliest cancers in the United States (i.e., lung, breast, prostate, and colorectal). For example, 7-year follow-up data from the Breast Cancer Prevention Trial (BCPT) provides evidence that tamoxifen reduces the occurrence of invasive breast tumors by more than 40%; recent studies using aromatase inhibitors and raloxifene are also promising. The Prostate Cancer Prevention Trial (PCPT) showed that finasteride reduced prostate cancer incidence by 25%, and the ongoing Selenium and Vitamin E Cancer Prevention Trial (SELECT) is investigating selenium and vitamin E for prostate cancer prevention based on encouraging results from earlier studies. Living a healthy lifestyle, including regular physical activity, avoiding obesity, and eating primarily a plant-based diet has been associated with a lower risk of colorectal cancer. In addition, noninvasive stool DNA tests for early detection are being studied, which may lessen the reluctance of people to be screened for colorectal polyps and cancer. Behavioral and medical approaches for smoking prevention are ways to reduce the incidence of lung cancer, with antinicotine vaccines on the horizon that may help former smokers to avoid relapse. The US National Lung Screening Trial is testing whether early detection via

  16. Breast cancer screening in Japan. Present status and recent movement

    International Nuclear Information System (INIS)

    As the incidence of breast cancer and deaths from breast cancer have been increasing, the Ministry of Public Welfare and Labor has been promoting breast cancer screening. Mammography screening began in fiscal year 2000 for those women 50 years of age or over, but attendance has not been increasing. This year (2004), the Ministry determined that mammography would be applicable to those 40 years of age or over and that screening with palpation alone would be abolished. To determine the effectiveness of the measures, mammography equipment, technologists, and readers were calculated. If the attendance were 50% of the 35,497 thousand women in this biennial screening, 40 persons would be examined by one apparatus per day, and, as there are 200 working days in a year, 1,109 apparatus would be needed. In the same way, if a technologist can examine 5,000 women, and a doctor can read 10,000 cases a year, both are apparently deficient in some prefectures. The standards of quality control for digital mammography have been determined by the Japan Radiological Society, and a ''step phantom for mammography'' has been developed. Qualitative evaluation of hard-copy clinical images has also started. All of the standards are presented in ''Mammography Guidelines, Second Edition,'' published by Igakushoin, Tokyo, Japan, 2004.

    Full Text Available OBJECTIVE To analyze the coverage of a cervical cancer screening program in a city with a high incidence of the disease in addition to the factors associated with non-adherence to the current preventive program. METHODS A cross-sectional study based on household surveys was conducted. The sample was composed of women between 25 and 59 years of age of the city of Boa Vista, RR, Northern Brazil who were covered by the cervical cancer screening program. The cluster sampling method was used. The dependent variable was participation in a women’s health program, defined as undergoing at least one Pap smear in the 36 months prior to the interview; the explanatory variables were extracted from individual data. A generalized linear model was used. RESULTS 603 women were analyzed, with an mean age of 38.2 years (SD = 10.2. Five hundred and seventeen women underwent the screening test, and the prevalence of adherence in the last three years was up to 85.7% (95%CI 82.5;88.5. A high per capita household income and recent medical consultation were associated with the lower rate of not being tested in multivariate analysis. Disease ignorance, causes, and prevention methods were correlated with chances of non-adherence to the screening system; 20.0% of the women were reported to have undergone opportunistic and non-routine screening. CONCLUSIONS The informed level of coverage is high, exceeding the level recommended for the control of cervical cancer. The preventive program appears to be opportunistic in nature, particularly for the most vulnerable women (with low income and little information on the disease. Studies on the diagnostic quality of cervicovaginal cytology and therapeutic schedules for positive cases are necessary for understanding the barriers to the control of cervical cancer.

    2016-03-01

    South Asian (SA) immigrants settled in the United Kingdom (UK) and North America [United States (US) and Canada] have low screening rates for breast, cervical and colorectal cancers. Incidence rates of these cancers increase among SA immigrants after migration, becoming similar to rates in non-Asian native populations. However, there are disparities in cancer screening, with low cancer screening uptake in this population. We conducted a scoping study using Arksey & O'Malley's framework to examine cancer screening literature on SA immigrants residing in the UK, US and Canada. Eight electronic databases, key journals and reference lists were searched for English language studies and reports. Of 1465 identified references, 70 studies from 1994 to November 2014 were included: 63% on breast or cervical cancer screening or both; 10% examined colorectal cancer screening only; 16% explored health promotion/service provision; 8% studied breast, cervical and colorectal cancer screening; and 3% examined breast and colorectal cancer screening. A thematic analysis uncovered four dominant themes: (i) beliefs and attitudes towards cancer and screening included centrality of family, holistic healthcare, fatalism, screening as unnecessary and emotion-laden perceptions; (ii) lack of knowledge of cancer and screening related to not having heard about cancer and its causes, or lack of awareness of screening, its rationale and/or how to access services; (iii) barriers to access including individual and structural barriers; and (iv) gender differences in screening uptake and their associated factors. Findings offer insights that can be used to develop culturally sensitive interventions to minimise barriers and increase cancer screening uptake in these communities, while recognising the diversity within the SA culture. Further research is required to address the gap in colorectal cancer screening literature to more fully understand SA immigrants' perspectives, as well as research to

  19. Effects of repeated mammographic screening on breast cancer stage distribution

    International Nuclear Information System (INIS)

    A randomised controlled trial of mass screening for breast cancer by single-view mammography was begun in Sweden in 1977. All women aged 40 and older and resident in the counties of Koppaberg and Oestergoetland were enrolled. The present report is confined to the Oestergoetland study, which started in 1978 and comprised 92934 women. After randomisation, which was done on the basis of communities rather than individuals, 47001 women were allocated to the study group and offered repeated mammographic screening; 45933 were allocated to the control group. As compliance among women over 74 years of age was poor these were excluded from the present report. The yearly incidence of stage II or more advanced breast cancers after the initial screening round up to and including the second was reduced by 40 per cent in the study group compared with the controls. This effect was less marked in the age group 40-49. After 5.5 years average from the date of entry the absolute number of women with stage II-IV disease in the control group exceeded that for the study group by 44, whereas there was a large excess of cancer in situ and stage I cancer in the study group.

    Full Text Available National Societies usually recommend screening for Prostate Cancer (PC with Serum Prostate Specific Antigen (PSA and digital rectal examination annually beginning at age 50. In high risk population including men with a family history of PC or African population screening should start at age of 45 years. PSA has been widely used to detect PC despite the fact that PSA is not specific for PC. Over the years serum PSA level of greater than 4,0ng/ml was considered the threshold to perform prostate biopsy, searching for PC. In 2005 the Prostate Cancer Prevention Trial (PCPT demonstrated that the cut-off of 4,0ng/ml for PSA is not anymore adapted1 due to the fact that this survey found in 15% of men with PSA < or = 4,0ng/ml a prostate cancer on sextant biopsies. Today the value of PSA and the cut-off for Prostate biopsy is questioned suggesting that PSA level higher than 2,6ng/ml must be the case to propose Prostate Biopsy. Catalona confirms that approximately 25% to 30% of men with PSA 2,6 to 4,0ng/ml have prostate cancer2. Schröder and Gosselaar3 assert that screening for PC at low PSA levels (<4,0ng/ml risks to detect clinically insignificant cancers which are no threat to man. So far in the year 2006 screening for PC demonstrates accumulating evidences of efficacy but persistent uncertainty4. The major question for an urologist at work when facing a young men searching early diagnosis of PC is: at which level of PSA do we have to perform rectal biopsy ?.

    Full Text Available Abstract Background U.S. cancer screening guidelines communicate important information regarding the ages for which screening tests are appropriate. Little attention has been given to whether breast, colorectal and prostate cancer screening test use is responsive to guideline age information regarding the age of screening initiation. Methods The 2006 Behavioral Risk Factor Social Survey and the 2003 National Health Interview Surveys were used to compute breast, colorectal and prostate cancer screening test rates by single year of age. Graphical and logistic regression analyses were used to compare screening rates for individuals close to and on either side of the guideline recommended screening initiation ages. Results We identified large discrete shifts in the use of screening tests precisely at the ages where guidelines recommend that screening begin. Mammography screening in the last year increased from 22% [95% CI = 20, 25] at age 39 to 36% [95% CI = 33, 39] at age 40 and 47% [95% CI = 44, 51] at age 41. Adherence to the colorectal cancer screening guidelines within the last year increased from 18% [95% CI = 15, 22] at age 49 to 19% [95% CI = 15, 23] at age 50 and 34% [95% CI = 28, 39] at age 51. Prostate specific antigen screening in the last year increased from 28% [95% CI = 25, 31] at age 49 to 33% [95% CI = 29, 36] and 42% [95% CI = 38, 46] at ages 50 and 51. These results are robust to multivariate analyses that adjust for age, sex, income, education, marital status and health insurance status. Conclusion The results from this study suggest that cancer screening test utilization is consistent with guideline age information regarding the age of screening initiation. Screening test and adherence rates increased by approximately 100% at the breast and colorectal cancer guideline recommended ages compared to only a 50% increase in the screening test rate for prostate cancer screening.

    Unprecedented progress has been made in genomic personalized medicine in the last several years, allowing for more individualized healthcare assessments and recommendations than ever before. However, most of this progress in prostate cancer (PCa) care has focused on developing and selecting therapies for late-stage disease. To address this issue of limited focus, we propose a model for incorporating genomic-based personalized medicine into all levels of PCa care, from prevention and screening to diagnosis, and ultimately to the treatment of both early-stage and late-stage cancers. We have termed this strategy the "Pyramid Model" of personalized cancer care. In this perspective paper, our objective is to demonstrate the potential application of the Pyramid Model to PCa care. This proactive and comprehensive personalized cancer care approach has the potential to achieve three important medical goals: reducing mortality, improving quality of life and decreasing both individual and societal healthcare costs.

    Human bocavirus (HBoV) is a prevalent virus worldwide and is mainly associated with respiratory disorders. Recently, it was detected in several disease conditions, including cancers. Colorectal cancer (CRC) is the third main cause of cancers worldwide. Risk factors that initiate cell transformation include nutritional, hereditary and infectious causes. The aim of the current study was to screen for the presence of HBoV in solid tumors of colorectal cancer and to determine the genotypes of the detected strains. Surgically excised and paraffin-embedded colorectal cancer tissue specimens from 101 male and female patients with and without metastasis were collected over the last four years. Pathological analysis and tumor stages were determined. The presence of HBoV was screened by polymerase chain reaction, and the genotype of the detected HBoV was determined by direct gene sequencing. Most of the examined specimens were adenocarcinoma with mucinous activity in many of them. Twenty-four out of 101 (23.8 %) CRC tissue specimens were found to contain HBoV-1. Low sequence diversity was recorded in the detected strains. The virus was detected in both male and female patients with an age range of 30-75 years. It is proposed that HBoV-1 could play a potential role in the induction of CRC. PMID:27155943

    The rate of breast cancer screening for women of all ages in Japan is increasing. However, little is known about the biological differences between screen- and self-detected tumors. We used data from the Japanese Breast Cancer Registry (JBCR), a nationwide registry of newly diagnosed breast cancer cases in Japan, to investigate patients diagnosed between January 1, 2004 and December 31, 2011. We compared the clinicopathological features of tumors and assessed yearly trends regarding the proportion of screen-detected cases during the study period. We found that 31.8 % (65,358/205,544) of cancers were detected by screening. Asymptomatic tumors detected by screening (asymptomatic) were more likely to have favorable prognostic features than those that were self-detected (ductal carcinoma in situ [DCIS]: 19.8 versus 4.1 %, node-negative: 77.0 versus 61.6 %, and estrogen receptor-positive [ER+]: 82.0 versus 72.9 %, respectively). All these findings were statistically significant (p DCIS increased from 41.5 to 66.0 % and that of ER+ cancers increased from 23.2 to 39.7 %. This study demonstrated that low-risk tumors, including DCIS, ER+, and lower TNM stage, account for a substantial proportion of clinical screening-detected cancers. The differences in biological characteristics between screen- and self-detected cancers may account in part for the limited efficacy of breast cancer screening programs aimed at improving breast cancer mortality.

  8. The impact of digital mammography on screening a young cohort of women for breast cancer in an urban specialist breast unit

    International Nuclear Information System (INIS)

    To compare the diagnostic performance of full-field digital mammography (FFDM) with screen-film mammography (SFM) in a corporate screening programme including younger women. Data were available on 14,946 screening episodes, 5010 FFDM and 9936 SFM. Formal analysis was by logistic regression, adjusting for age and calendar year. FFDM is compared with SFM with reference to cancer detection rates, cancers presenting as clustering microcalcifications, recall rates and PPV of recall. Overall detection rates were 6.4 cancers per thousand screens for FFDM and 2.8 per thousand for SFM (p < 0.001). In women aged 50+ cancer detection was significantly higher for FFDM at 8.6 per thousand vs. 4.0 per thousand, (p = 0.002). In women <50, cancer detection was also significantly higher for FFDM at 4.3 per thousand vs. 1.4 per thousand, (p = 0.02). Cancers detected as clustering microcalcifications increased from 0.4 per thousand with SFM to 2.0 per thousand with FFDM. Rates of assessment recall were higher for FFDM (7.3% vs. 5.0%, p < 0.001). FFDM provided a higher PPV for assessment recall, (32 cancers/364 recalls, 8.8%) than SFM, (28 cancers/493 recalls, 5.7%). Cancer detection rates were significantly higher for FFDM than for SFM, especially for women <50, and cancers detected as clustering microcalcifications. (orig.)

    Risk of lung cancer in A-bomb survivors is reportedly increased. The screening in the title has been conducted since 1988 and this report summarizes its results of the latest 6-year term (2004-2009). The total number of subjects who visited authors' facility for the screening in the period was 39,147 men (average age 70.6 y) and 45,351 women (71.8 y), of the age range of 60-89 y. The screening results of the cancer were examined concerning with sex, age and exposure situation. As well, the relationship between the found cancer incidence and exposure in never, formerly and currently smoking subjects were also examined. Exposure situation was divided in 3 groups of the exposure by entrance in the city/by other reasons, within 2 km close (Close, C) to, and out of 2.1 km afar (Distant, D) from, the city. Statistic analysis was performed by Chi-squire and/or Fisher's exact test. The index of positive finding in the screening of the lung cancer per 1,000 subjects was the highest in C men of ages 70s, 2.88 subjects, which was statistically significant from 0.85 in D men of the same generation. In current smokers, the index 5.40 in C men of ages 70s was significantly higher than 0.90 in D men of the same generation. Overall, positive results tended to be high in survivors of C regardless to sex and smoking, and was significantly high in current smokers of C as above, both implying the particular necessity of promotion to stop smoking in survivors.

    Screening for psychological distress in patients with cancer is currently being debated in the British Journal of Cancer. Screening has been recommended, as elevated levels of distress have been consistently observed and clinicians tend to overlook the need of psychological support (Carlson et al, 2012; Carlson et al, 2013; National Comprehensive Cancer Network, 2013). On the other hand, it has been argued that screening should not be implemented, as the true benefit of screening and subseque...

    To reveal the role of key elements present in the hair of breast cancer patients on cancer development, the levels of a number of elements in scalp hair samples of 82 people including healthy individuals, people suffering from benign breast disease, and breast cancer patients were measured by PIXE analysis. Pellets of hair samples were prepared and bombarded by 2.2 MeV proton beam of a 3-MV Van de Graaff accelerator. The number of incident ions hitting the sample was indirectly measured using the RBS spectrum of a thin Ag film placed in the beam path. The concentrations of S, Cl, K, Ca, Fe, and Cu in the hair of healthy individuals were in agreement with those observed in the hair of hyperplasia and cancer patients within standard deviations. However, a lower average level of zinc was found in samples from hyperplasia and breast cancer patients. Strong positive correlations were found between iron and potassium as well as between calcium and potassium in the cancer patients. These results could be of significance in the screening for breast cancer. PMID:23625730

    Full Text Available IntroductionIn 2005, the Centers for Disease Control and Prevention funded five sites to implement the Colorectal Cancer Screening Demonstration Program (CRCSDP. An evaluation is being conducted that includes a multiple case study. Case study results for the start-up period, the time between initial funding and screening initiation, provide details about the program models and start-up process and reveal important lessons learned.MethodsThe multiple case study includes all five CRCSDP sites, each representing a unique case. Data were collected from August 2005 through September 2006 from documents, observations, and more than 70 interviews with program staff and stakeholders.ResultsSites differed by geographic service area, screening modality selected, and service delivery structure. Program models were influenced by two factors: preexisting infrastructure and the need to adapt programs to fit local service delivery structures. Several sites modeled program components after their National Breast and Cervical Cancer Early Detection Program. Medical advisory boards convened by all sites provided clinical support for developing program policies and quality assurance plans. Partnerships with comprehensive cancer control programs facilitated access to financial and in-kind resources.ConclusionThe program models developed by the CRCSDP sites offer a range of prototypes. Case study results suggest benefits in employing a multidisciplinary staff team, assembling a medical advisory board, collaborating with local partners, using preexisting resources, designing programs that are easily incorporated into existing service delivery systems, and planning for adequate start-up time.

    Breast cancer is the most frequently diagnosed cancer in women. Early detection of breast cancer is known to increase survival rates significantly after diagnosis. This research was carried out to determine the level of breast cancer risk among primary healthcare nurses and their belief in breast cancer screening. In this descriptive research, the data were collected in face-to-face interviews with the participants. The researchers contacted all primary healthcare nurses currently working in the province. The data collection tools included a questionnaire form on sociodemographic characteristics, breast cancer risk assessment form, and Champion's Health Belief Model Scale (CHBMS) for breast cancer screening. In data analysis, descriptive statistics, t test, and analysis of variance (ANOVA) were used. The mean age of nurses was 35 ± 3.6. The mean score for the breast cancer risk assessment form was calculated as 82.9 ± 18.7. The subscale scores for the CHBMS for breast cancer screening were as follows: susceptibility 7.3 ± 1.8, seriousness 19.5 ± 4.1, benefits of breast self-exam 15.5 ± 2.6, barriers to breast self-exam 15.1 ± 2.8, self-efficacy 40.3 ± 7.0, and motivation 19.5 ± 4.1. The risk of breast cancer was found to be low in the study group. The analysis of the subscale scores for the CHBMS for breast cancer screening revealed that nurses had a below-average susceptibility perception, a somewhat lower perception of seriousness, an above-average mean score for perceived benefits, a moderate barrier perception, a relatively high perceived self-efficacy, and motivation above average.

    2013-11-01

    Anal cancer is a rare malignancy of the distal gastrointestinal tract, often associated with human papillomavirus, the most common sexually transmitted infection worldwide. Currently available screening methods for anal intraepithelial neoplasia, a precursor for anal cancer, combine anal Papanicolaou cytology and high resolution anoscopy with biopsy of suspicious lesions. Significant barriers to establishing anal cancer screening programmes include the small number of healthcare professionals performing high resolution anoscopy and the lack of data showing that anal cancer screening can reduce morbidity and mortality related to anal carcinoma. Despite several controversies surrounding anal cancer screening, the rising incidence of this disease in some groups supports routine screening programmes in high-risk populations, especially in HIV-positive men who have sex with men. This review outlines the epidemiology of anal intraepithelial neoplasia and anal cancer and summarizes issues related to the introduction of anal cancer screening programmes. PMID:23970583

  19. Improved detection of breast cancer on FDG-PET cancer screening using breast positioning device

    International Nuclear Information System (INIS)

    The aim of this study was to investigate the detection rate of breast cancer by positron emission tomography cancer screening using a breast positioning device. Between January 2004 and January 2006, 1,498 healthy asymptomatic individuals underwent cancer screening by fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) at our institution; 660 of 1498 asymptomatic healthy women underwent breast PET imaging in the prone position using the breast positioning device to examine the mammary glands in addition to whole-body PET imaging. All subjects that showed abnormal 18F-FDG uptake in the mammary glands were referred for further examination or surgery at our institution or a local hospital. Our data were compared with the histopathological findings or findings of other imaging modalities in our institution and replies from the doctors at another hospital. Of the 660 participants, 7 (1.06%) were found to have breast cancers at a curable stage. All the seven cancers were detected by breast PET imaging, but only five of these were detected by whole-body PET imaging; the other two were detected by breast PET imaging using the breast positioning device. In cancer screening, prone breast imaging using a positioning device may help to improve the detection rate of breast cancer. However, overall cancer including mammography and ultrasonography screening should be performed to investigate the false-negative cases and reduce false-positive cases. The effectiveness of prone breast PET imaging in cancer screening should be investigated using a much larger number of cases in the near future. (author)
