Our results indicate that both LCNBB and DVABB are reliable and safe techniques in the diagnosis of non-palpable breast lesions. However, the use of 14-G LCNBB seems to be advantageous in masses, the use of 11-G DVABB seems to be advantageous in asymmetric densities and calcifications.
We describe a new dedicated ultrasound system for computer-guided large core breast biopsy (LCBB) and report our first clinical experience in 45 female patients. After an initial 30 biopsy procedures on a US breast phantom, LCBB using this new system was performed in 45 non-palpable surgically verified breast lesions. All biopsies were performed by the same radiologist using 14-gauge long-throw biopsy needles. Histological results following LCBB were compared with open surgical biopsy. Procedure time and any complication arising was registered in all procedures. Biopsies using this prototype were successful and yielded sufficient material in all 45 lesions. There were 23 benign and 22 malignant lesions with complete histological agreement between LCBB and open surgical biopsy in 44 of the 45 lesions. In one invasive ductal cancer the pathologist could only state high probability of malignancy but not give a definite diagnosis. Besides one case with early termination due to decreased visibility of the target lesion, no technical complications were noted. Slight vasovagal reactions were seen in 4 patients but did not alter the histological results. The average procedure time was 30+/-2.7 min. This new dedicated US system for computer-guided LCBB is an accurate and safe method for diagnosing breast lesions. Although this new system may have no major impact for US-guided LCBB experienced physicians, it might be a promising alternative for the non-skilled physician to currently available breast biopsy techniques.
Use of CNBB as an alternative to OSB has the potential to substantially reduce healthcare costs. The data are based almost exclusively on the North American literature. A potential cost reduction in the Netherlands and Switzerland confirms these findings. Future work must include cost evaluation studies for German-speaking countries since this is an issue with important national economic ramifications.
It can be expected that molecular imaging of breast tumors will enable a simultaneous assessment of the multiple metabolic and molecular processes involved in cancer development and thus an improved detection, characterization, staging and monitoring of response to treatment will become possible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
