原始语种摘要: Aims(#br)Matrix‐assisted laser desorption/ionisation mass spectrometry imaging ( MALDI ‐ MSI ) and tissue microarray ( TMA ) technologies were jointly utilized to search for molecular features associated with clinicopathological parameters in oesophageal cancer.(#br)Methods and results(#br)Two TMAs from formalin‐fixed tissue samples, including 300 adenocarcinomas and 177 squamous cell carcinomas with clinical follow‐up data, were analysed. MALDI‐MSI analysis revealed 72 distinct mass per charge ( m / z ) signals associated with tumour cells, 48 of which were found in squamous cell carcinomas only, and 12 of which were specific for adenocarcinomas. In adenocarcinomas, six signals were linked to early‐stage ( pT 1–T2) tumours (two signals) and the presence (one signal) or absence (three...
