Abstract

A subtype of non-small cell lung cancer, bronchioalveolar adenocarcinoma (BAC), is more prevalent in Asian female non-smokers, and is more likely to respond to treatment with tyrosine kinase inhibitors such as erlotinib and gefitinib. Nuclear magnetic resonance and mass spectrometry-based metabolomic analysis of extracts from two different lung lesions and surrounding non-cancerous tissues of a BAC patient showed novel protein and phospholipid-associated metabolic differences that correlated with tumor development as well as PET and erlotinib sensitivity.

摘要

细支气管肺泡腺癌(BAC)是一种非小细胞肺癌亚型,在亚洲不吸烟女性中更为常见,并且更有可能对诸如厄洛替尼和吉非替尼等酪氨酸激酶抑制剂治疗产生反应。对一名BAC患者的两种不同肺部病变及周围非癌组织提取物进行基于核磁共振和质谱的代谢组学分析,结果显示出与肿瘤发展以及PET和厄洛替尼敏感性相关的新的蛋白质和磷脂相关代谢差异。
