Consideration of breast diseases diagnosed as class III by aspiration biopsy cytology. Comparison of class III a with class III b groups.

Abstract

過去7年3ヵ月間に長野県がん検診センターの乳腺外来で穿刺吸引細胞診 (ABC) を施行した乳腺疾患1,215例中の乳癌症例295例に対するABCの正診率は86.1%であり, 良性疾患917例の正診率は83.3%であったが, class III判定がおのおの14例, 4.7%および62例, 6.8%にみられた. class III症例76例をclass III a 51例とclass III b25例に分けて比較検討した結果 以下の結論を得た.1) class III症例中のclass III bの割合は乳癌が64.3%と最も多く, ついで乳腺症が40.9%で, 線維腺腫は9.5%と少なかった.2) class III a群中の乳癌比率は9.8%であり, class III b群では36.0%であった.3) 触診で乳癌と診断した群では差がみられなかったが, 乳腺症と診断した群ではclass III b群の方がclass III a群より乳癌比率が高かった.4) Mammography診断が良性 (I・II) で, ABCがclass III aの場合には乳癌はなかったが, class III bの場合には1/3強が乳癌であった. 悪性 (IV・V) の場合はclass III aでも乳癌の可能性が高かった.5) Echography診断が良性~疑診 (I~III) で, ABCがclass IIIaの場合には乳癌は少なかったが, class III bの場合には30%弱が乳癌であった. 悪性 (IV・V) の場合はclass III a, III bに関係なく乳癌であった.6) Thermography診断が良性 (I・II) で, ABCがclass III aの場合には乳癌は少なかったが, class III bの場合は1/3が乳癌であった. 悪性 (IV・V) の場合はABCがclass III bの場合は半数が乳癌であった.以上の成績からABCのclass III判定例をclass III aとclass III bに分ける意義が窺われた.
