The objective of this study was to develop a standard diagnostic evaluation with 16G core-needle biopsy for breast lesions. We evaluated the ideal number of fragments using standard ultrasound criteria based on the previous results obtained on the size of the lesions.
A prospective study was carried out, from may 2004 to September 2005, in 79 patients with lesions that included categories 2,3,4 and 5, according to BIRADS -USTM using 16G core biopsy needle. We took up 5 pieces numbered and placed individually in vials with 10% formalin.
In 84 biopsies performed there were 81 conclusive diagnoses (96%), with 43 malignant results (51%) and 38 benign results (45%). The effectiveness of the core biopsy increased with the sample numbers: one sample is 95.24% accurate; two samples reach 96.93%; three samples reach 98.8%; four samples reach 98.81%, and finally, five samples reach 100% accuracy.
the resection of three fragments was sufficient for a satisfactory result.
本研究的目的是开发一种用于乳腺病变的16G粗针活检标准诊断评估方法。我们根据先前获得的病变大小结果，使用标准超声标准评估理想的碎片数量。
2004年5月至2005年9月，对79例根据BIRADS -USTM分类为2、3、4和5类病变的患者进行了前瞻性研究，使用16G活检针。我们取了5块标本，编号后分别放入装有10%福尔马林的小瓶中。
在进行的84次活检中，有81次得出结论性诊断（96%），其中恶性结果43例（51%），良性结果38例（45%）。粗针活检的有效性随样本数量增加：一个样本的准确率为95.24%；两个样本达到96.93%；三个样本达到98.8%；四个样本达到98.81%，最后，五个样本的准确率达到100%。
切除三个碎片足以获得满意的结果。
