CHARACTERISTICS OF ULTRASOUND IMAGING IN CLINICAL BREAST CANCER SPECIFIC PERIOD 2011-2014 Oncology Kotabaru
ABSTRACT: Background: Burden of disease due to breast cancer is still high in Indonesia. It is recommended by American Cancer Society to do breast self-exam, clinical breast exam, and mammography for early breast cancer detection. However, breast cancer incidence rate in young women tends to increase and be more aggressive. Mammography, as a diagnostic tool detecting breast cancer, is less sensitive for young women. As a consequence, it is necessary to have a breast ultrasound as an adjunct to mammography. Objective: To explain the characteristics of breast cancer on breast ultrasound. Method: This is an observational descriptive study of 32 subjects diagnosed with breast cancer by pathology test as the gold standard. All subjects had undergone breast ultrasound. The results would be reevaluated by a radiologist after Kappa intraobserver agreement had been done. Results: Kappa intraobserver agreement results of 8 characteristics observed were as follows: mass (1), orientation (1), architectural distortion (1), number of mass (0,78), skin thickening (0,74), lesion boundary (0,44), calcification (0,21), and edema (0,21). Of 32 subjects, mass was detected (96,88%), single (54, 84%), 1-3 cm in size (67,74%), irregular-shaped (35,48%), indistinct margin (32,25%), not parallel orientation (64,52%), echogenic halo lesion boundary (54,84%), complex echo pattern (48,59%), combined posterior acoustic feature pattern (54,48%), macro- and micro-calcification (21,88%), duct changes (15,63%), edema (9,38%), architectural distortion (100%), and skin thickening (37,50%). Conclusion: On breast ultrasound, most of the breast cancer were seen as an irregular single mass, 1-3 cm in diameter, with indistinct margin, complex echo pattern and echogenic halo lesion boundary. Its orientation was not parallel with combined shadowing and enhancement posterior acoustic feature pattern. In malignant mass, macro- and micro-calcification, architectural distortion, duct changes, edema and skin thickening might be seen.
