Assessment of Diagnostic Accuracy of Digital Breast Tomosynthesis in Distinguishing Malignant and Benign Breast Lesions

Abstract

Objective: The study aims to determine the diagnostic accuracy of digital breast tomosynthesis in diagnosing malignant and benign lesions, keeping histopathology as the gold standard. Study Design: Cross-sectional study. Place and Duration of Study: The study was carried out at the Department of Diagnostic Radiology, POF th th Hospital, Wah Cantt, Pakistan over a period of six months from 11th July 2021 to 11th January 2022. Methods: A total of 200 women presenting with suspicion of breast malignancy were selected consecutively from the outpatient department, and Digital Breast Tomosynthesis(DBT) was performed, followed by a biopsy of the specimen to confirm the findings on histopathology. Results: The average age of the sample was 48.3 + 7.1 years, ranging between 35 and 60 years. Palpable breast lump was recorded in 44.5%, pain in 33%, and nipple discharge in 35.5%. Family history of breast Ca was present in 25.5. On Digital Breast Tomosynthesis (DBT), 58.5% of lesions were labeled as malignant, while 53.5% were labeled as malignant on follow-up histopathology. On applying the formulae for calculation, the sensitivity of DBT was found to be 86% and specificity 73.1%. The positive predictive value of the DBT is 78.6%, and the negative predictive value is 81.9%. Conclusion: In conclusion, Digital Breast Tomosynthesisis a significantly sensitive and specific tool for detecting malignant breast lesions in women suspected of breast carcinoma.
