L‑type amino acid transporter 1 (LAT1) has emerged as a critical molecular target for advancing boron neutron capture therapy (BNCT), a promising treatment that leverages selective boron accumulation and neutron irra‑ diation to eradicate cancer cells. The frequent upregulation of LAT1 in aggressive tumors (such as gliomas and specific subtypes of lung and breast cancer) underpins its essential role as the principal mediator of tumor‑selective boron compound uptake in BNCT. The present review comprehensively exam‑ ines the structure and function of LAT1, the mechanistic principles of boron transport (including LAT1 mediation) and the key regulatory pathways governing BNCT efficacy. Building on this and given the role ofLAT1 in reprogramming tumor metabolism through amino acid transport, advanced metabolomics tools, particularly liquid chromatography‑mass spectrometry and nuclear magnetic resonance, offer a novel approach for clarifying the contribution of LAT1 to BNCT. These techniques hold significant potential to map metabolic profiles altered by LAT1‑mediated boron compound uptake, thereby elucidating downstream biochemical consequences relevant to the therapeutic efficacy and resistance mechanisms. Synthesizing the dual role of LAT1 as both a vulnerability and therapeutic target in BNCT, the present review system‑ atizes key challenges, including the need for selective boron  \nCorrespondence to: Dr Wei Shao, Precision Medicine Application and Transformation Central Laboratory, Xiamen Humanity Hospital, Fujian Medical University, 3777 Xianyue Road, Xiamen, Fujian 361000, P.R.
