“…15-18 Mammographically guided FNAB with and without special stereotoxic unit has also been applied to nonpalpable breast lesions and a high degree of diagnostic accuracy has been achieved. [19][20][21][22][23] These studies have mostly focused on defining precise cytologic criteria used to distinguish between benign and malignant processes in breast fine-needle aspirates. However, it is also important to differentiate low-risk benign changes from those known to pose a high risk of subsequent malignancy, as this knowledge may help the patient and clinician in their long-term management of breast problems.…”

Fine-needle aspiration biopsy (FNAB) is considered a valid diagnostic procedure in management of patients with breast lesions. It is also important to differentiate benign nonproliferative change from proliferative breast changes, since the risk of development of breast carcinoma in patients with atypical hyperplasia is 4-5 times that of general population. Therefore, the recognition of proliferative breast disease with atypia significantly impacts on the patient's subsequent management. To assess the feasibility of a cytologic grading system to further characterize benign breast lesions, cytologic preparation of 87 mammographically guided FNABs were studied. Cellular aspirates were evaluated for the cellular arrangement, the degree of cellular pleomorphism and anisonucleosis, presence of myoepithelial cells and nucleoli and the status of the chromatin pattern. Values ranging from 1 to 4 were assigned to each cytologic criterion, and a score based on the sum of the individual values was calculated for each case. The minimum score attainable was thus 6. In our chosen criteria cytologic diagnosis of nonproliferative disease was entertained when the total score ranged from 6 to 10. Proliferative disease without atypia was diagnosed with a total score ranging from 11 to 14. Atypical hyperplasia was reported when the total score ranged from 15 to 18. A cytologic diagnosis of malignancy was entertained when the total score ranged from 19 to 24. The cytologic diagnosis was then compared to the reported histologic diagnosis from the excisional biopsies and the data were statistically analysed. A high degree of concordance was found between the cytologic findings and the histologic diagnosis. This study suggests that it is possible to apply a cytologic grading system to further subclassify benign breast disease and distinguish these forms from neoplastic lesions.

“…Over the past 25 years, following the studies by Bolmgren et al and Nordenström and Zajicek [4,5], numerous stereotactic needle biopsy techniques have been devised [6,7,8,9,10,11,12]. The need for a trained cytopathologist and the high rate of insufficient samples are drawbacks of fine-needle aspiration biopsy technique, which have led to the increased use of automated large-core-needle biopsy [13,14].…”

This study was prospectively conducted to assess the feasibility, safety and accuracy of an 8-G directional vacuum-assisted biopsy (DVAB) probe in the diagnostic management of nonpalpable breast lesions (NPBL). Of 170 planned procedures which were indicated for investigation of BI-RADS category-3 to category-5 lesions, 153 were performed in 138 consecutive patients. The probe was targeted by the stereotactic unit of a prone table (United States Surgical Corporation, Norwalk, Conn.; and Lorad, Danbury, Conn.). Four to 18 (mean 8) core specimens were obtained for each lesion. In case of complete removal of the lesion, a localizing clip was deployed at the biopsy site. Adequate material for histopathologic examination was obtained in all cases (100%). Four of 138 (3%) patients experienced mild hematomas. We observed 15 of 39 failures (38%) to place the localizing clips. Thirteen of 153 (8%) procedures were inconclusive and required reintervention. Following DVAB, 42 of 138 (30%) patients underwent surgery. Subject to incomplete follow-up of the entire cohort, we observed no false-positive and one false-negative diagnosis. These preliminary results suggest that DVAB using an 8-G probe are feasible, safe and accurate. In our experience, clip placement was problematic. It is probable that increasing the dimensions of DVAB will only be relevant in a limited number of clinical situations, primarily the desire to obtain complete radiologic resections of the target abnormality.

“…Early stereotactic approaches using twoangled views to give a three-dimensional coordinate for needle placement were hampered by the delays of analogue film processing and patient movement. 16 The breakthrough into smallfield digital technology was a spin-off of the Hubble Space Telescope in the mid-1990s, when a joint project between National Aeronautics and Space Administration and Scientific Imaging Technologies developed a new charged-couple device. 17 The technology allowed a high resolution, wide dynamic range and low light sensitivity, shortening exposure time while preserving image quality, resulting in the LORAD Stereo Guided Breast Biopsy System.…”

This article discusses the significance of microcalcifications on mammography and the changes in technology that have influenced management; it also describes a pragmatic approach to investigation of microcalcification in a UK screening programme. BACKGROUND AND PREVALENCE OF MICROCALCIFICATIONSMicrocalcifications result from the deposition of calcium oxalate and calcium phosphate within the breast tissue. The mechanism by which calcium deposition occurs is not clearly understood; it may be an active cellular process, or an effect of cellular degeneration. Calcification deposits are found within the ductal system, the breast acini, stroma and vessels, mainly as calcium oxalate and calcium phosphate.
