- W2947051726 abstract "Objective: To evaluate the risk of cancer associated with ACR3 and ACR4 microcalcifications. Patients and methods: A retrospective study of 96 out of 5204 patients who underwent mammography was conducted for 5 years (January 2008 to December 2012). We confronted cancer lesions with ACR3 and ACR4 microcalcifications. Results: Cancer was detected in 201women, with a prevalence of 3.8%. Among the 96 cases of ACR3 and ACR4 microcalcifications detected, 56 cases (58%) were classified as ACR3, and 40 cases (42%) as ACR4. For all ACR3 and ACR4microcalcifications, it was noted 30% of them represented cancerous lesions against 70% of benign lesions. The sensitivity (Se) was 14.4%, specificity (Sp) was 98.66 %, positive predictive value (PPV) was 30% and negative predictive value (NPV) was 96.63%. For ACR3 microcalcifications, cancerous lesions represented for 11 against 89% of benign lesions. The Se was 3%, Sp was 99%, PPV was 11% and NPV was 96%. For ACR4 microcalcifications, cancerous lesions were noted in 57.5% against 42.5% of benign lesions. The Se was 11.4%, Sp was 99.6%, PPV was 57.5% and NPV was 96.5%. Conclusion: In our study, the risk of cancer associated with ACR3 microcalcifications was 11% against 57.5% ACR4 microcalcifications." @default.
