ROLE OF MAMMOGRAPHY AND CORE BIOPSY IN THE DIAGNOSIS OF BREAST TUMOR
Introduction: Breast tumor is a popular disease. Breast cancer is the most common cancer in women. Mammography is the chosen screening test and ultrasound-guided core-needle biopsy provides (US-CNB) the pathologic result for treatment. Objective: To study the role of mammography and core biopsy in diagnosis of breast tumors. Materials and methodology: Prospective and retrospective study of 33 breast tumors examined mammograms at Hue University Hospital and Hue Central Hospital from 7/2014 to 4/2017. Results: Mean age of breast cancer: 52 years old, of benign breast disease: 53 years old. 86% of all cases admitted to hospital due to self-detecting breast tumor. Locations: 0-3h 33.3%, 9-12h 27.2%. Sensitivity, specificity and accuracy of mammography were 76.9%, 28.6% and 66.7% respectively. Sensitivity, specificity, positive predictive value, negative predictive value, accuracy value of US-CNB were 95.2%, 85.6%, 95.2%, 85.6% and 92.9%, respectively. The value of combined with mammograms and US-CNB has improved the specificity and positive predictive value to 100%, accuracy value to 95.2%. Moreover, this combination discovered 7.1% breast cancer more. Conclusion: US-CNB is a safe and less traumatic diagnostic tool with high pathologic efficiency. Combining mammography and US-CNB increases the diagnostic value. Key words: Breast tumor, breast cancer, mammograms
