Lipid intensity ratio heat-maps showing the clustering of the intensity ratios of lipid head groups (A) and SM species (B) in the SQCC and ADC cohorts. The intensity ratios of lipid head groups show no prominent changes between the non-recurrent and recurrent groups of the SQCC cohort, whereas a broad range of lipid head groups is increased in the recurrent ADC group (A). The intensity ratios of SM species in the recurrent SQCC group demonstrated that lipid decreases were limited to SM(t34:1) and SM(d35:1). In contrast, the recurrent ADC group showed increases in a broad range of SM species. The full spellings of abbreviations for lipids are provided in Additional file 1, Sheets 2 and 3. Abbreviations: ADC, adenocarcinoma; SM, sphingomyelin; SQCC, squamous cell carcinoma
