Purpose
BACKGROUND
- An ultrasound-guided core needle biopsy is an invaluable tool for the diagnosis of breast lesions. However, the possibility of inaccurate sampling with histologic underestimation of lesions, such as ductal carcinoma in situ (DCIS) has been unavoidable.
- Underestimation of DCIS occurs when a lesion is determined to be DCIS after a percutaneous breast biopsy and is subsequently shown to be invasive carcinoma following surgical excision.
- In a review of the literature, most prior studies of underestimating DCIS have been performed using stereotactic devices, However, underestimating DCIS after a US-CNB of a breast mass as compared to the use of a stereotactic biopsy has not been thoroughly evaluated.
PURPOSE
- The purpose of this study is to determine the rate of underestimation of DCIS after an ultrasound-guided 14-gauge core needle biopsy of a breast masse and to compare the clinical and imaging characteristics between DCIS lesions and underestimated DCIS lesions identified following surgical excision.
