“…In the present study, the PPV based on percutaneous biopsy (TP results/number of biopsies in categories 4 and 5) was 48.6%, superior to the expected range according to the literature (15% to 40%) ( 14 , 37 - 42 ) . Remarkably, category 3 presented a PPV of 1.3%, reproducing the values reported by Sickles et al ( 37 ) .…”

“…Such a result is superior to the one reported by Sickles et al ( 37 ) (93.1%) and by Baines et al ( 38 ) (69%), but reproduces the recommendations by Basset et al ( 14 ) (> 85%). The specificity observed in the present study was 97.4% and studies in the literature recommend results > 90% ( 14 , 37 , 38 , 42 ) . The authors attribute such results to the experience of the medical team (minimum 10-year training in breast imaging) and also to the quality of the mammography services provided by the center.…”

ObjectiveUndertaking of a complete audit of the service of mammography, as recommended by BI-RADS®, in a private reference institution for breast cancer diagnosis in the city of São Paulo, SP, Brazil, and comparison of results with those recommended by the literature.Materials and MethodsRetrospective, analytical and cross-sectional study including 8,000 patients submitted to mammography in the period between April 2010 and March 2011, whose results were subjected to an internal audit. The patients were followed-up until December 2012. ResultsThe radiological classification of 7,249 screening mammograms, according to BI-RADS, was the following: category 0 (1.43%), 1 (7.82%), 2 (80.76%), 3 (8.35%), 4 (1.46%), 5 (0.15%) and 6 (0.03%). The breast cancer detection ratio was 4.8 cases per 1,000 mammograms. Ductal carcinoma in situ was found in 22.8% of cases. Positive predictive values for categories 3, 4 and 5 were 1.3%, 41.3% and 100%, respectively. In the present study, the sensitivity of the method was 97.1% and specificity, 97.4%.ConclusionThe complete internal audit of a service of mammography is essential to evaluate the quality of such service, which reflects on an early breast cancer detection and reduction of mortality rates.

“…Taking these problems into consideration, the development of quality control programs represents a necessity in terms of efficiency, and an obligation in ethical and moral terms (3) . The imaging quality reduces, although does not eliminate, the occurrence of false-positive and falsenegative results.…”

OBJECTIVE: The present study was aimed at evaluating the quality and the impact of an intervention involving inspection and education in mammography centers of the Federal District, Brazil. MATERIALS AND METHODS: Forty one mammography centers in the Federal District were studied in the period between 2000 and 2002. The intervention involved an initial inspection followed by a training activity and notification of mammography centers by the Federal District Sanitary Vigilance authority. The imaging quality was compared before and after the intervention. RESULTS: None of the 36 centers which completed the study reached more than 90% compliance with the standard imaging quality prior to the interventions, whereas ten were above 90% afterwards. Major improvements were observed in chassis maintenance, breast compression and visualization of microcalcifications. CONCLUSION: Despite the availability of a great number of mammography centers in the Federal District, most of them did not meet the required quality standards. The intervention has shown to be effective for improving the imaging quality, however a continued action is required to solve the remaining problems and increase the impact of the program. Keywords: Mammography; Quality control; Federal District; Impact. OBJETIVO: Esta pesquisa visou a avaliar a qualidade dos serviços de mamografia do Distrito Federal e o impacto de uma intervenção de inspeção e capacitação. MATERIAIS E MÉTODOS: Foram estudados 41 serviços de mamografia no Distrito Federal no período de 2000 a 2002.A intervenção consistiu na inspeção inicial seguida de um treinamento e notificação oficial da Vigilância Sanitária. Os resultados de qualidade da imagem foram comparados "antes" e "depois" da intervenção. RESULTADOS: O estudo demonstrou que dos 36 serviços que completaram a pesquisa, nenhum estava acima de 90% de conformidade antes da intervenção. Após a intervenção, dez unidades atingiram mais de 90%. As principais melhorias foram em relação aos chassis, compressão da mama e visualização de microcalcificações. CONCLUSÃO: Apesar de o Distrito Federal dispor de muitos serviços, na sua maioria não eram de qualidade. A intervenção foi eficaz para a melhoria da qualidade, porém, torna-se necessária uma ação continuada para resolver os problemas restantes e aumentar o impacto.

ObjectiveTo evaluate the results of screening and diagnostic mammography in a geographically defined population attending a regional mastology referral hospital of the State Public Service of São Paulo.MethodsA total of 7508 women, who received screening or diagnostic mammography examinations from 06/2004 to 06/2005, with follow-up until 06/2006, were included in this study. Data corresponding to age, the Breast Imaging-Reporting and Data System (BI-RADS), biopsy, surgery and the stage of breast cancer were collected. Five-year survival of patients with breast cancer was posteriorly calculated during this period.ResultsThis study included a total of 713 diagnostic and 6795 screening mammograms. The average age of the population was 51.2 years, with a BI-RADS end result of 4 and 5 (abnormal) in 1.9% of the screening and 11.4% of the diagnostic mammograms, respectively. All BI-RADS category zero was complemented. Of the 228 nonsurgical biopsies performed (71 CNB, 94 mammotomy and 63 FNAB), 63 (27.6%) biopsies were malignant findings. Among the 33 surgical biopsies, 10 (30.3%) biopsies were malignant findings, and of the 82 surgeries, 55 (67, 1%) procedures showed malignant findings. Seventy-one (0.9%) breast cancers (25/6795 on screening exams and 46/713 on diagnostics) were diagnosed. A total of 28.6% small cancers (≤10 mm) were observed, with 27% of the cancers in stages zero and I. Approximately 47.6% of the cases showed nodal invasion, and 4.5% of cases were not staged. Overall detection rate of breast cancer was 8.8/1000 (3.2/1000 screening and 61.7/1000 diagnostic). The overall 5-year survival rate of patients with breast cancer in this population was 79.1%.ConclusionSurvival is a key index of the overall effectiveness of health services in the management of patients with cancer. Our results suggest that this approach is feasible and can potentially improve breast cancer outcomes for many women in São Paulo.
