Validity of Ultrasonographic Findings Based on Acr-Birads Scores to Diagnosis Breast Diseases in Sulaimani Breast Disease Treatment Center

Abstract

Background 
 Breast diseases are common in females all over the world. Breast cancer is the second common causes of concept mortality; early detection of breast cancer promotes outcomes.
 Objectives
 To evaluate the validity of ultrasonographic findings based on American College of Radiology Breast-Imaging Reporting and Data System (ACR-BIRADS) in diagnosis of breast diseases, and determine sensitivity and specificity of ultrasonographic finding in breast and axillary lesions in Sulaimani breast disease treatment centre.
 Materials and Methods
 This retrospective descriptive study was performed on 427 patients with different breast and axillary lesions at Sulaimani breast disease treatment center, from January 2014 till December of 2018. Ethical consideration by the regulatory bodies was followed. Information was recorded according to inclusion criteria by using a questionnaire paper. Finding of ultrasonography by using ACR-BIRADS system was compared with histopathology reports, The Chi-square test was used and the obtained results were judged statistically significant at P≤0.05, P-value < 0.001 is regarded as highly significant. statistical analysis was performed using statistical package for social science SPSS (version 21).
 Results
 Age range was 22-84 years old, average age of participants with the standard deviation was 45.32(±11.763). 128 (30.0%) and 125 (29.3%) of all breast lesions were in the range of BIRADS 5 and 3 respectively. Among 427 cases, most of the breast lesions 222 (52.2%) were malignant on histopathology, while 205 (47.8%) were benign on histopathology. Sensitivity; Specificity of ultrasound for breast was 87.38%, 85.85%, respectively. Also Sensitivity, Specificity of ultrasound for axilla was 78.16%, 10%, respectively. In finding correlation between ACR-BIRADS system and histopathology results using chi square P-value was < 0.001 which is highly significant for both breast and axilla.
 Conclusions
 Sensitivity and specificity of using ultrasound based on ACR-BIRADS scores in diagnosis of breast pathology were high; it makes a good way for diagnosis of breast diseases. But using BIRADS ultrasound system as sole investigation in diagnosis of breast pathology is the matter of debate. Using ultrasound based on Sensitivity and specificity for axilla didn’t make it an ideal way for diagnosis of pathological lymph nodes.
