摘 要:目的探讨通过人体呼出气体鉴定乳腺癌分子分型的可能性。方法筛选出251例符合入组标准的研究对象,每人收集2份呼气样本,分别经热脱附-气相色谱-质谱(TD-GC—MS)技术及纳米传感器技术检测。结果发现13种可挥发性有机化合物(VOCs)浓度在人类表皮生长因子受体-2(HER-2)过表达型乳腺癌与非HER-2过表达患者间存在显著差异(P〈0.05),三阴型乳腺癌与非三阴型乳腺癌间5种,Luminal B型乳腺癌与非Luminal B型乳腺癌间1种,Luminal A型乳腺癌与非Luminal A型乳腺癌间0种。纳米传感器经留一法交叉验证判别各分子分型的乳腺癌时亦获得较高的精确度(73.64%~90.70%)、灵敏度(40.00%~93.75%)与特异度(73.77%~93.42%)。结论“呼气检测”可作为一种新型的鉴定乳腺癌分子分型的无创检查方法。Objective To explore the feasibility of discriminating the molecular sub-types of breast cancer ( BC ) by exhaled breath. Methods The exhaled breath samples were collected from 251 volunteers. The samples were analyzed by thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS) and nano-sensor respectively. Results Apparent differences of 13 volatile organic compounds (VOCs) were found between HER-2 over-expression BC patients and non-HER-2 over expression BC patients (P 〈 0.05) ;5 between triple-negative BC patients and non-triple-negative BC patients; 1 between Luminal B BC patients and non-Luminal B BC patients, 0 between Luminal A BC patients and non-Luminal A BC patients. High accuracy(73.64% -90. 70% ) , sensitivity(40. 00% 93.75% ) , specificity (73.77% -93.42% ) also were found to distinguish the molecular sub-types of BC by the test using nano-sensor. Conclusion "Breath test" may be a new noninvasive diagnostic method for discriminating the molecular sub-types of BC.
