A randomized study was performed on patients in whom the clinical decision had already been made to excise a breast lump. The objective was to assess the difference in diagnostic results of 21 and 23 G needles in the fine needle aspiration cytology (FNAC) of breast lumps. Following induction of anaesthetic, (local or general), FNAC was performed with either a 21 or 23 G needle. The breast lump was then excised and the histology and cytology results analysed routinely. One hundred and twenty-five excised breast lumps were included. Sixty-one had FNAC performed with a 21 G needle and 64 had FNAC performed with a 23 G needle. Of the 61 21 G FNAC, histology revealed 45 breast cancers. Of the 64 23 G FNAC, 50 patients had breast cancer. There was no statistical difference between these two results. There is no difference in the cytological yield when a 21 G needle is compared with that of a 23 G needle.
对已做出切除乳腺肿块临床决策的患者进行了一项随机研究。目的是评估21G和23G针头在乳腺肿块细针穿刺细胞学检查（FNAC）中的诊断结果差异。在麻醉诱导（局部或全身）后，用21G或23G针头进行FNAC。然后切除乳腺肿块，并常规分析组织学和细胞学结果。共纳入125个切除的乳腺肿块。61个用21G针头进行FNAC，64个用23G针头进行FNAC。在61例21G FNAC中，组织学显示45例为乳腺癌。在64例23G FNAC中，50例患者患有乳腺癌。这两个结果之间没有统计学差异。与23G针头相比，21G针头的细胞学取材率没有差异。
