Öğe A Risk Assessment Comparison of Breast Cancer and Factors Affected to Risk Perception of Women in Turkey: A Cross-sectional Study(Iranian Scientific Society Medical Entomology, 2017) Yüksel, Serpil; Altun Uğraş, Gülay; Çavdar, İkbal; Bozdoğan, Atilla; Gürdal, Sibel Özkan; Akyolcu, Neriman; Özmen, VahitBackground: The increase in breast cancer incidence has enhanced attention towards breast cancer risk. The aim of this study was to determine the risk of breast cancer and risk perception of women, factors that affect risk perception, and to determine differences between absolute risk and the perception of risk. Methods: This cross-sectional study was carried out among 346 women whose score in the Gail Risk Model (GRM) was >= 1.67% and/or had a 1(st) degree relative with breast cancer in Bahcesehir town in Istanbul, Turkey between Jul 2012 and Dec 2012. Data were collected through face-to-face interviews. The level of risk for breast cancer has been calculated using GRM and the Breast Cancer Risk Assessment Form (BCRAF). Breast cancer risk perception (BCRP), has been evaluated by visual analogue 100-cm-long scale. Results: Even though 39.6% of the women considered themselves as high-risk carriers, according to the GRM and the BCRAF, only 11.6% and 9.8% of women were in the high risk category, respectively. There was a positive significant correlation between the GRM and the BCRAF scores (P<0.001), and the BCRAF and BCRP scores (P<0.001). Factors related to high-risk perception were age (40-59 yr), post-menopausal phase, high-very high economic income level, existence of breast cancer in the family, having regular breast self-examination and clinical breast examination (P<0.05). Conclusion: In women with high risk of breast, cancer there is a significant difference between the women's risk perception and their absolute risk level.Öğe Bahcesehir long-term population-based screening compared to National Breast Cancer Registry Data: effectiveness of screening in an emerging country(Turkish Soc Radiology, 2021) Gürdal, Sibel Özkan; Özaydın, Ayşe Nilüfer; Arıbal, Erkin; Özçınar, Beyza; Cabıoğlu, Neslihan; Şahin, Cennet; Özmen, VahitPURPOSE We aimed to show the effects of long-term screening on clinical, pathologic, and survival outcomes in patients with screen-detected breast cancer and compare these findings with breast cancer patients registered in the National Breast Cancer Registry Data (NBCRD). METHODS Women aged 40-69 years, living in Bahcesehir county, Istanbul, Turkey, were screened every 2 years using bilateral mammography. The Bahcesehir National Breast Cancer Registry Data (BMSP) data were collected during a 10-year screening period (five rounds of screening). BMSP data were compared with the NBCRD regarding age, cancer stage, types of surgery, tumor size, lymph node status, molecular subtypes, and survival rates. RESULTS During the 10-year screening period, 8758 women were screened with 22621 mammograms. Breast cancer was detected in 130 patients; 51 (39.2%) were aged 40-49 years. The comparison of breast cancer patients in the two programs revealed that BMSP patients had earlier stages, higher breast-conserving surgery rates, smaller tumor size, more frequent negative axillary nodal status, lower histologic grade, and higher ductal carcinoma in situ rates than NBCRD patients (p = 0.001, for all). CONCLUSION These results indicate the feasibility of successful population-based screening in middle-income countries.Öğe Bahcesehir mammography screening project (BMSP) is cost-effective in a developing country(Amer Assoc Cancer Research, 2016) Özmen, Vahit; Cabıoğlu, Neslihan; Gürdal, Sibel Özkan; Özaydın, Ayşe Nilüfer; Kayhan, Arda; Arıbal, Erkin[No Abstract Available]Öğe Comparison of Intermittent Pneumatic Compression with Manual Lymphatic Drainage for Treatment of Breast Cancer-Related Lymphedema(Mary Ann Liebert, Inc, 2012) Gürdal, Sibel Özkan; Kostanoglu, Alis; Çavdar, İkbal; Özbaş, Ayfer; Cabıoğlu, Neslihan; Özçınar, Beyza; Özmen, VahitBackground: The aim of this prospective controlled study was to assess the efficacy of two different combination treatment modalities of lymphedema (LE). Manual lymphatic drainage (MLD) and compression bandage combination (complex decongestive therapy) have been compared with intermittent pneumatic compression (IPC) plus self-lymphatic drainage (SLD). Methods and Results: Both MLD with compression bandage (complex decongestive therapy) group (Group I, n = 15) and IPC with SLD group (Group II, n = 15) received treatment for LE 3 days in a week and every other day for 6 weeks. Arm circumferences were measured before and the 1st, 3rd, and 6th weeks of the treatment. EORTC-QLQ and ASES-tests were performed to assess the quality of life before and after 6 week-treatment. Patients in both groups had similar demographic and clinical characteristics. Even though both treatment modalities resulted in significant decrease in the total arm volume (12.2% decrease in Group II and 14.9% decrease in Group I) (p < 0.001), no significant difference (p = 0.582) was found between those two groups. Similarly, ASES scores were significantly (p = 0.001) improved in both Group I and II without any significant difference between the groups. While emotional functioning, fatigue, and pain scores were significantly improved in both groups, global health status, functional and cognitive functioning scores appeared to be improved only in patients of group I. Conclusions: Different treatment modalities consisting of MLD and compression bandage(complex decongestive therapy) or IPC and SLD appear to be effective in the treatment of LE with similar therapeutic efficacy in patients with breast cancer. However, combination modalities including IPC and SLD may be the preferred choices for their applicability at home.Öğe Comparison of Qualitative and Volumetric Assessments of Breast Density and Analyses of Breast Compression Parameters and Breast Volume of Women in Bahcesehir Mammography Screening Project(Galenos Yayincilik, 2020) Gemici, Ayşegül Akdogan; Arıbal, Erkin; Özaydın, Ayşe Nilüfer; Gürdal, Sibel Özkan; Özçınar, Beyza; Cabıoğlu, Neslihan; Özmen, VahitObjective: We aimed to compare visual and quantitative measurements of breast density and to reveal the density profile with compression characteristics. Materials and Methods: Screening mammograms of 1399 women between May 2014 and May 2015 were evaluated by using Volpara 4th and 5th version. First 379 mammograms were assessed according to ACR BI-RODS 4th- edition and compared to Volpara. We categorized the breast density in two subgroups as dens or non-dens. Two radiologists reviewed the images in consensus. Agreement level between visual and volumetric methods and volumetric methods between themselves assessed using weighted kappa statistics. Volpara data such as fibroglandular volume (FGV), breast volume (BV), compression thickness (CT), compression force (CF), compression pressure (CP) were also analyzed with relation to the age. Results: 1399 mammograms were distributed as follows: 12.7% VDG1, 39.3% VDG2, 34.1% VDG3, 13.9% VDG4 according to the 4th edition of Volpara; 1.2% VDC1, 46% VDG2, 36.8% VDG3, 15.9% VDG4 according to the 5 -5 edition of Volpara. The difference between two editions was 4.7% increase in dense cat. -gory. 379 mammograms, according to ACR BI-BADS 4th edition, were distributed as follows: 25.9% category A, 50.9% category B, 19.8% category C, 3.4% category D. The strength of agreement between the Volpara 4th and 5th editions was found substantial (k= 0.726). The agreements between visual assessment and both Volpara editions were poor (k=- 0.413, k-0.399 respectively). There was a 142% increase in dense group with the VDG 4th edition and 162% with the VDG 5th edition when compared to visual assessment. Compression force decreased while compression pressure increased with incasing Volpara Density Grade (VDG) (p for trend <0.001 for both). Compression thickness and breast volume decreased with increasing VDG (p for trend <0.001 for both).The FGV decreases with age and the breast volume increases with increasing age (p<0.001). Conclusion: Visual assessment of breast density doesn't correlate well with volumetric assessments. Obtaining additional information about physical parameters and breast profile by the results of quantified methods is important for breast cancer risk assessments and prevention strategies.Öğe Cost-Effectiveness of Breast Cancer Screening in Turkey, a Developing Country: Results from Bahçeşehir Mammography Screening Project(Aves Press Ltd, 2017) Özmen, Vahit; Gürdal, Sibel Özkan; Cabıoğlu, Neslihan; Özçınar, Beyza; Özaydın, Ayşe Nilüfer; Kayhan, Arda; Alagöz, OğuzhanObjective: We used the results from the first three screening rounds of Bahcesehir Mammography Screening Project (BMSP), a 10-year (20092019) and the first organized population-based screening program implemented in a county of Istanbul, Turkey, to assess the potential cost-effectiveness of a population-based mammography screening program in Turkey. Materials and Methods: Two screening strategies were compared: BMSP (includes three biennial screens for women between 40-69) and Turkish National Breast Cancer Registry Program (TNBCRP) which includes no organized population-based screening. Costs were estimated using direct data from the BMSP project and the reimbursement rates of Turkish Social Security Administration. The life-years saved by BMSP were estimated using the stage distribution observed with BMSP and TNBCRP. Results: A total of 67 women (out of 7234 screened women) were diagnosed with breast cancer in BMSP. The stage distribution for AJCC stages O, I, II, III, IV was 19.4%, 50.8%, 20.9%, 7.5%, 1.5% and 4.9%, 26.6%, 44.9%, 20.8%, 2.8% with BMSP and TNBCRP, respectively. The BMSP program is expected to save 279.46 life years over TNBCRP with an additional cost of $ 677.171, which implies an incremental cost-effectiveness ratio (ICER) of $ 2.423 per saved life year. Since the ICER is smaller than the Gross Demostic Product (GDP) per capita in Turkey ($ 10.515 in 2014), BMSP program is highly cost-effective and remains cost-effective in the sensitivity analysis. Conclusion: Mammography screening may change the stage distribution of breast cancer in Turkey. Furthermore, an organized population-based screening program may be cost-effective in Turkey and in other developing countries. More research is needed to better estimate life-years saved with screening and further validate the findings of our study.Öğe Factors Predicting Microinvasion in Ductal Carcinoma in situ(Asian Pacific Organization Cancer Prevention, 2014) Gürdal, Sibel Özkan; Cabıoğlu, Neslihan; Özçınar, Beyza; Müslümanoğlu, Mahmut; Özmen, Vahit; Keçer, Mustafa; İğci, AbdullahBackground: Whether sentinel lymph node biopsy (SLNB) should be performed in patients with pure ductal carcinoma in situ (DCIS) of the breast has been a question of debate over the last decade. The aim of this study was to identify factors associated with microinvasive disease and determine the criteria for performing SLNB in patients with DCIS. Materials and Methods: 125 patients with DCIS who underwent surgery between January 2000 and December 2008 were reviewed to identify factors associated with DCIS and DCIS with microinvasion (DCISM). Results: 88 patients (70.4%) had pure DCIS and 37 (29.6%) had DCISM. Among 33 DCIS patients who underwent SLNB, one patient (3.3%) was found to have isolated tumor cells in her biopsy, whereas 1 of 14 (37.8%) patients with DCISM had micrometastasis (7.1%). Similarly, of 16 patients (18.2%) with pure DCIS and axillary lymph node dissection (ALND) without SLNB, none had lymph node metastasis. Furthermore, of 20 patients with DCISM and ALND, only one (5%) had metastasis. In multivariate analysis, the presence of comedo necrosis [relative risk (RR)=4.1, 95% confidence interval (CI)=1.6-10.6, P=0.004], and hormone receptor (ER or PR) negativity (RR=4.0, 95% CI=1.5-11, P=0.007), were found to be significantly associated with microinvasion. Conclusions: Our findings suggest patients presenting with a preoperative diagnosis of DCIS associated with comedo necrosis or hormone receptor negativity are more likely to have a microinvasive component in definitive pathology following surgery, and should be considered for SLNB procedure along with patients who will undergo mastectomy due to DCIS.Öğe First Round Results of A Long Term Population- Based Breast Cancer Screening Program From Bahcesehir(Aves, 2012) Kayhan, Arda; Gürdal, Sibel Özkan; Özaydın, Ayşe Nilüfer; Öztürk, Enis; Cabıoğlu, Neslihan; Arıbal, Erkin; Özmen, VahitIntroduction: The Bahcesehir Breast Cancer Screening Project is the first organized population based breast cancer screening project in Turkey. The objectives of this prospective observational study are to determine implementation of a population-based organized breast cancer screening program in Turkish women and to find out the effect of screening on stage shift. Materials and Methods: A total of 3758 women within 40-69 years of age were recruited in this prospective study. The screening was done biannually and five rounds were planned. After completing a clinical breast examination (CBE), two-view mammograms were obtained and classified according to Breast Imaging Reporting and Data System (BI-RADS) of the American College of Radiology (ACR). True positivity, false positivity, positive predictive values (PPV) according to ACR, cancer detection rate, minimal cancer detection rate, axillary node positivity and recall rate were calculated. Results: Seventeen cancers were detected in the first round. The overall cancer detection rate was 4.5 per 1000 women. Minimal cancer detection rate and axillary node positivity were 52.9 % and 11.7 %, respectively. A positive prediction for biopsy was 32%. The overall recall rate was 18.4 %. Discussion: These are the first round results of the screening project. Our results showed that screening can be done effectively in a population based organization.Öğe Molecular profiles of screen detected breast cancers: Final results of Turkish Bahcesehir breast cancer screening project(Amer Assoc Cancer Research, 2013) Cabıoğlu, Neslihan; Gürdal, Sibel Özkan; Kayhan, Arda; Özaydın, Ayşe Nilüfer; Özçınar, Beyza; Arıbal, Erkin; Özmen, Vahit[No Abstract Available]Öğe Molecular profiles of screen-detected breast cancers from a Turkish breast cancer screening program(Lippincott Williams & Wilkins, 2013) Cabıoğlu, Neslihan; Gürdal, Sibel Özkan; Kayhan, Arda; Özaydın, Nilüfer; Arıbal, Erkin; Özmen, Vahit[No Abstract Available]Öğe Poor Biological Factors and Prognosis of Interval Breast Cancers: Long-Term Results of Bahceehir (Istanbul) Breast Cancer Screening Project in Turkey(Amer Soc Clinical Oncology, 2020) Cabıoğlu, Neslihan; Gürdal, Sibel Özkan; Kayhan, Arda; Özaydın, Niluefer; Şahin, Cennet; Can, OEmuer; Özmen, VahitPURPOSE The Turkish Bahceehir Breast Cancer Screening Project was a 10-year, organized, population-based screening program carried out in Bahceehir county, Istanbul. Our aim was to examine the biologic features and outcome of screen-detected and interval breast cancers during the 10-year study period. METHODS Between 2009 and 2019, 2-view mammograms were obtained at 2-year intervals for women aged 40 to 69 years. Clinicopathological characteristics including ER, PR, HER2-neu, and Ki-67 status were analyzed for those diagnosed with breast cancer. RESULTS In 8,758 screened women, 131 breast cancers (1.5%) were detected. The majority of patients (82.3%) had prognostic stage 0-I disease. Contrarily, patients with interval cancers (n = 15; 11.4%) were more likely to have a worse prognostic stage (II-IV disease; odds ratio [OR], 3.59, 95% CI, 0.9 to 14.5) and high Ki-67 scores (OR, 3.14; 95% CI, 0.9 to 11.2). Interval cancers detected within 1 year were more likely to have a luminal B (57.1% v 31.9%) and triple-negative (14.3% v 1%) subtype and less likely to have a luminal A subtype (28.6% v 61.5%; P = .04). Patients with interval cancers had a poor outcome in 10-year disease-specific (DSS) and disease-free survival (DFS) compared with those with screen-detected cancers (DSS: 68.2% v 98.1%, P = .002; DFS: 78.6% v 96.5%, P = .011). CONCLUSION Our findings suggest the majority of screen-detected breast cancers exhibited a luminal A subtype profile with an excellent prognosis. However, interval cancers were more likely to have aggressive subtypes such as luminal B subtype or triple-negative cancers associated with a poor prognosis requiring other preventive strategies. (c) 2020 by American Society of Clinical OncologyÖğe Radiologic findings of screen-detected cancers in an organized population-based screening mammography program in Turkey(Aves, 2016) Kayhan, Arda; Arıbal, Erkin; Şahin, Cennet; Tasci, Omur Can; Gürdal, Sibel Özkan; Öztürk, Enis; Özmen, VahitPURPOSE Bahcesehir Breast Cancer Screening Program is a population based organized screening program in Turkey, where asymptomatic women aged 40-69 years are screened biannually. In this prospective study, we aimed to determine the mammographic findings of screen-detected cancers and discuss the efficacy of breast cancer screening in a developing country. METHODS A total of 6912 women were screened in three rounds. The radiologic findings were grouped as mass, focal asymmetry, calcification, and architectural distortion. Masses were classified according to shape, border, and density. Calcifications were grouped according to morphology and distribution. Cancers were grouped according to the clinical stage. RESULTS Seventy cancers were detected with an incidence of 4.8/1000. Two cancers were detected in other centers and three were not visualized mammographically. Mammographic presentations of the remaining 65 cancers were mass (47.7%, n= 31), calcification (30.8%, n= 20), focal asymmetry (16.9%, n= 11), architectural distortion (3.1%, n= 2), and skin thickening (1.5%, n= 1). The numbers of stage 0, 1, 2, 3, and 4 cancers were 13 (20.0%), 34 (52.3%), 14 (21.5%), 3 (4.6%), and 1 (1.5%), respectively. The numbers of interval and missed cancers were 5 (7.4%) and 7 (10.3%), respectively. CONCLUSION A high incidence of early breast cancer has been detected. The incidence of missed and interval cancers did not show major differences from western screening trials. We believe that this study will pioneer implementation of efficient population-based mammographic screenings in developing countries.Öğe Screen detected breast cancers exhibit good clinicopathological characteristics: Updated results of Turkish Bahcesehir Breast Cancer Screening Project(Elsevier Sci Ltd, 2016) Cabıoğlu, Neslihan; Gürdal, Sibel Özkan; Kayhan, Arda; Özaydın, Ayşe Nilüfer; Özçınar, Beyza; Arıbal, Erkin; Özmen, Vahit[No Abstract Available]Öğe Successful First Round Results of a Turkish Breast Cancer Screening Program with Mammography in Bahcesehir, Istanbul(Asian Pacific Organization Cancer Prevention, 2014) Kayhan, Arda; Gürdal, Sibel Özkan; Özaydın, Ayşe Nilüfer; Cabıoğlu, Neslihan; Öztürk, Enis; Özçınar, Beyza; Özmen, VahitBackground: The Bahcesehir Breast Cancer Screening Project is the first organized population based breast cancer mammographic screening project in Turkey. The objective of this prospective observational study was to demonstrate the feasibility of a screening program in a developing country and to determine the appropriate age (40 or 50 years old) to start with screening in Turkish women. Materials and Methods: Between January 2009 to December 2010, a total of 3,758 women aged 40-69 years were recruited in this prospective study. Screening was conducted biannually, and five rounds were planned. After clinical breast examination (CBE), two-view mammograms were obtained. True positivity, false positivity, positive predictive values (PPV) according to ACR, cancer detection rate, minimal cancer detection rate, axillary node positivity and recall rate were calculated. Breast ultrasound and biopsy were performed in suspicious cases. Results: Breast biopsy was performed in 55 patients, and 18 cancers were detected in the first round. The overall cancer detection rate was 4.8 per 1,000 women. Most of the screened women (54%) and detected cancers (56%) were in women aged 40-49. Ductal carcinoma in situ (DCIS) and stage I cancer and axillary node positivity rates were 22%, 61%, and 16.6%, respectively. The positive predictivity for biopsy was 32.7%, whereas the overall recall rate was 18.4 %. Conclusions: Preliminary results of the study suggest that population based organized screening are feasible and age of onset of mammographic screening should be 40 years in Turkey.Öğe Surgical Trends in Breast Cancer in Turkey: An Increase in Breast-Conserving Surgery(Amer Soc Clinical Oncology, 2020) Çakmak, Güldeniz Karadeniz; Emiroglu, Selman; Sezer, Atakan; Cantürk, Nuh Zafer; Yeniay, Levent; Kuru, Bekir; Özmen, Vahit; Gürdal, Sibel ÖzkanPURPOSEBreast cancer is the most frequent cancer in women, and there is a great variability in surgical practice for treating that cancer in different countries. The aims of this study were to analyze the effect of guidelines from the Turkish Federation of Breast Diseases Societies on academic institutions that have breast centers and to evaluate surgical practice in Turkey in 2018.PATIENTS AND METHODSBetween January and March 2019, a survey was sent to breast surgeons who were working in breast centers in academic institutions. The sampling frame included 24 academic institutions with breast centers in 18 cities in Turkey to evaluate interdisciplinary differences among breast centers and seven regions in Turkey regarding patients' choices, surgical approaches, and academic institutions.RESULTSAll surgeons responded to the survey, and all 4,381 patients were included. Most of the surgeons (73.9%) were working in a breast center. Multidisciplinary tumor boards were performed in 87% of the breast centers. The average time between clinical evaluation and initiation of treatment was 29 days; the longest time was in Southeast Anatolia (66 days). Only 6% of patients had ductal carcinoma in situ. Sentinel lymph node biopsy was available in every region across the country and was performed in 64.5% of the patients. In 2018, the overall breast-conserving surgery rate was 57.3% in Turkey, and it varied from 72.2% in the Black Sea region to 33.5% in Central Anatolia (P < .001). Oncoplastic breast surgery options were available at all breast centers. However, 25% of the breast centers from the Black Sea region and half the breast centers from Eastern Anatolia and the Mediterranean region did not perform this type of surgery.CONCLUSIONIncreasing rates of nonpalpable breast cancer and decreasing rates of locoregional recurrences favored breast-conserving surgery, especially in developed countries. Guidelines from the Turkish Federation of Breast Diseases Societies resulted in more comprehensive breast centers and improved breast health in Turkey.Öğe The incremental value of magnetic resonance imaging for breast surgery planning(Springer, 2013) Gürdal, Sibel Özkan; Özçınar, Beyza; Kayahan, Munire; Iğcı, Abdullah; Tunaci, Mehtap; Özmen, Vahit; Muslumanoglu, MahmutThe aim of this study was to evaluate the effect of breast magnetic resonance imaging (MRI) on preoperative or intraoperative surgical planning. One hundred and sixty females with breast cancer were enrolled in the study. The contribution of MRI compared to MMG and USG, their histopathological concordance, and their impact on surgical treatment were evaluated prospectively. In 48 (30.0%) of the patients, MRI identified suspicious lesions that were not detected by MMG and USG. The diagnosis by MRI was accurate in 17 (10.6%) of them, while in remaining 31 patients (19.4%) the additional lesions found by MRI and interpreted as malignant were found not to be malignant. The pathological accordance of MRI and MMG compared with USG were 69.3 and 70.0%, respectively, whereas individually, MMG and USG were in accordance with the pathological examination in 52.9 and 67.9% of the cases, respectively. Assessment of the tumor size, multifocality, multicentricity, and presence of ductal carcinoma in situ by MRI may lead to misinterpretations in the majority of patients. The surgical approach should not be changed based solely on MRI findings. An accurately interpreted MMG combined with USG may be sufficient in most cases.Öğe Uzun dönem toplum tabanlı Bahçeşehir meme kanseri tarama procesinin ilk dönem sonuçları(2012) Kayhan, Arda; Gürdal Özkan, Sibel; Özaydın, Ayşe Nilüfer; Öztürk, Enis; Cebioğlu, Neslihan; Arıbal, Erkin; Özmen, VahitGiriş: Bahçeşehir Meme Kanseri Tarama Projesi, Türkiye'nin 10 yıl sürecek olan toplum tabanlı organize meme kanseri tarama projesidir. Bu prospektif gözlemsel çalışmanın amacı Türk kadınlarında toplum tabanlı meme kanseri tarama programının uygulanabilirliğini belirlemek ve taramanın evre değişikliklerindeki etkisini ortaya koymaktır. Materyal-Metod: Bu prospektif çalışmaya 40-69 yaş arasında toplam 3758 kadın dahil edildi. Tarama, iki yıllık dönemlerle toplam beş dönem uygulanmak üzere planlandı. Mamogramlar, klinik meme muayenesi sonrasında, Amerikan Radyoloji Koleji'nin (ARK) Meme Görüntüleme Raporlama ve Veri Sistemi'ne (BI-RADS) göre iki ayrı radyolog tarafından değerlendirildi. Gerçek pozitiflik, yalancı pozitiflik, ARK'ye göre pozitif prediktif değerler (PPD), kanser saptama oranı, minimal kanser saptama oranı, aksiller lenf nodu pozitifliği ve geri çağırma oranı hesaplandı. Sonuç: Birinci dönemde 17 kanser saptandı. Bunların %23.4'ü duktal karsinoma in situ, %64.7'si ise evre I meme kanseri idi. Kanser yakalama oranı 4.5/1000 idi. Minimal kanser saptama oranı %52,9, aksiller lenf nodu pozitifliği %11,7, biyopsi için pozitif prediktivite değeri %32, tüm geri çağırma oranı %18,4 idi. Tartışma: Bu bulgular, tarama projesinin ilk turunun verileri olup, toplum tabanlı organize bir çalışmada taramanın etkin olarak yapılabileceğini ve hastaların önemli bir kısmında çok erken tanı konulabileceğini göstermiştir.
