FEBLES, Gustavo; ESTELLANO, Fernando  and  SIMON, Oscar. Auditoría de los resultados de la mamografía diagnóstica en el Centro de Diagnóstico Mamario de la Asociación Española. Rev. Méd. Urug. [online]. 2009, vol.25, n.1, pp.5-13. ISSN 1688-0390.

Summary Objective: to evaluate the performance of diagnostic mammography at the "Centro de Diagnóstico Mamario (CENDIMA) of the Asociación Española". Method: we calculated the positive predictive value, cancer detection rate, cancer minimum percentage, average size of the invading cancer, negative axilla percentage and percentages for stages 0 and I. Results were compared to reference parameters provided by the Breast Cancer Surveillance Consortium (BCSC). Results: positive predictive value of all positive mammographies BI-RADS 4 and 5 was 62% (over P90 according to the BCSC database). Positive predictive value of all biopsies actually performed was 55% (P75 to P90). Cancer detection rate was 9 /1,000 (< P10). Minimum percentage was 36% (P25 to P50). 130 invasive cancer cases were diagnosed, average size was 10 mm (P25 a P50). Negative axilla percentage was 72% (P50 to P75). Stage 0 and stage I cancer percentage was 61% (P50). Conclusions: parameters found indicate CENDIMA’s performance, in terms of breast cancer, agrees with most centers for breast diagnosis in the United States. Cancer detection rate is low for a diagnosis center, due to the fact that the population studied is mainly comprised of asymptomatic women.
