Introduction: Introduction: Breast cancer is 5th most common cause of cancer deaths today. It is the commonest inevitable cancer in women and is the second commonest cancer after cancer of the cervix in India.
Aim: To evaluate the effectiveness of elastography in the differentiation and characterisation of benign and malignant breast masses.
Materials and Methods: The present prospective study conducted from August 2010 to July 2012 in all patients who came to Kamineni Hospital, Hyderabad for screening or with symptoms of lump or pain in the breast in the department of radiology.
Results: A total of 51 women accounting to 57 lesions were evaluated during the study period. Most of the patients were in the age group of 51-60 years. The mean age of the patients was 48.6 years (range 17-77 years). Amongst the symptomatic patients, palpable lump was the most common presentation (58%). Patients who had come for routine mammographic screening accounted for 23.53% (12/51 patients). The frequency of other complaints were: pain and lump in 3.92% patients, and retracted nipple in 3.92% patients. Lumps in both breasts were seen in 1.96% of women who had a past history of vaginal cancer. One patient (1.96%) had past history of carcinoma of contralateral breast. The number of malignant lesions in our study was 25 (49.02%) and benign was 26 (50.98%) in histipathological examination. The ratio of malignant to benign lesions was 0.96. 40 patients had undergone mammography. Abnormal results in the form of mass lesions/calcifications/asymmetry could be identified in 37 patients. In three patients no obvious abnormality could be detected on mammography. In this study sensitivity, specificity, PPV and NPV of sonomammography were 92.00%, 73.1%, 76.67% and 90.4% respectively. the sensitivity, specificity, positive predictive value and negative predictive value for detecting malignant lesions in elastography were 84%, 96.1%, 95.4% and 86.2% respectively.
Conclusion: Elastography has more specificity and positive predictive value compared to mammography and ultrasonography. Elastography has similar diagnostic performance as ultrasonography.
