The discovery of new laryngeal cancer‐related metabolite biomarkers could help to facilitate early diagnosis. A serum metabolomics study from laryngeal cancer patients and healthy individuals was conducted using liquid chromatography coupled with quadrupole time‐of‐flight mass spectrometry. Univariate and multivariate statistics were used to discriminate laryngeal cancer patients and healthy individuals. 1‐Palmitoyl‐sn‐glycero‐3‐phosphocholine (LysoPC 16:0), 1‐ o ‐hexadecyl‐2‐acetyl‐sn‐glycero‐3‐phosphocholine (PAF) and 1,2‐dipalmitoyl‐sn‐glycero‐3‐phosphocholine were found to be significantly different between the laryngeal cancer group and the healthy group. They are mainly involved in phospholipids catabolism, linoleic acid metabolism, α ‐linoleic acid metabolism and arachidonic acid metabolism. The area under the curve of the biomarker combined by two metabolites (LysoPC 16:0 and PAF) was 0.935, the sensitivity was 0.962 and the specificity was 0.825. LysoPC 16:0 and PAF may show diagnostic potential for laryngeal carcinoma.
