| Sumario: | Minimally invasive core breast biopsy methods are replacing hook-wire-guided surgery wherever ultrasound and stereotactic equipment are available. Cost efficiency is improved, but sampling errors inherent in these techniques cause underestimations of malignancy and the degree of invasiveness in a small but significant number of patients. Diagnostic accuracy improves with increasing specimen weight. The trend is to take many cores. How much tissue is enough to enable a confident diagnosis? Recent research suggests that 1 g of tissue is sufficient. A new coaxial biopsy method presented here can retrieve a contiguous 1-g block of tissue from the center of a mammographic lesion, without stereotactic guidance. This specimen may be superior to multiple small cores obtained by biopsy guns and vacuum devices. Copyright © 2000 by W.B. Saunders Company Copyright © 2000 by W.B. Saunders Company |
