Aos colegas da lista. Uma segunda leitura das mamografias, melhora a acurácia e a sensibilidade para detecção de câncer inicial, diminuindo os falso negativos. Durante o estudo, foram revisados 25.368 mamogramas. A taxa de reconvocação total foi 14% ou 3.588 mulheres. O primeira leitura foi responsável por 3.209 das reconvocações e a segunda leitura adicionou 379. Das mulheres reconvocadas, 676 foram biopsiadas. A primeira leitura foi responsável por 634 das biópsias, e a segunda por 42. Os resultados das biópsias mostraram um total de 139 malignidades das quais 11 estavam em mulheres reconvocadas pela segunda leitura. O que aumentou a taxa de diagnóstico de câncer em 7.9%. Este trabalho foi apresentado dia 04 de Maio de 2001, no 101st annual meeting of the American Roentgen Ray Society, pela Dra. Susan Harvey, que também afirmou durante sua conferência que a segunda leitura é rápida, leva de 30 segundos a 1 minuto por caso. MAIS DETALHES: Double Reading of Mammograms Increases Cancer Detection Rate ---------------------------------------------------------------------------- ---- ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- SEATTLE (Reuters Health) May 04 - Routine double reading of mammograms may help improve the accuracy and sensitivity of the screening, according to study results presented Thursday at the 101st annual meeting of the American Roentgen Ray Society. Dr. Susan Harvey presented data on the initial experience of independent double readings at Fletcher Allen Health Care in Burlington, Vermont. The second reading is rapid, she explained to conference attendees. "It takes between 30 seconds to a minute per case, depending on the case and the radiologist. The second reader in this method can add but not delete recalls." During the study period, 25,368 mammograms were reviewed. The total recall rate was 14% or 3588 women. The first reader was responsible for 3209 of the recalls and the second reader added 379. Of the women recalled, 676 were biopsied. The first reader initiated 634 of the biopsies, and second reader was responsible for 42. The biopsy results showed a total of 139 malignancies, of which 11 were in women recalled by the second reader. Dr. Harvey said that the increased cancer detection rate was 7.9%. The expenses generated by the second reading and additional imaging, biopsies and pathology totaled $111,000. This amounts to about $10,000 per additional cancer detected, Dr. Harvey pointed out. "Our recall rate was increased by 1.5%, and our current second read has been modified," she told meeting attendees. "We are now doing a consensus double reading because of this data, and in an effort to decrease our recall rate and cost."
