MALDI-MS analysis of PM vs matched healthy peritoneum from PT21_11 and PT21_14 patients. A Intra-patient mass spectra peaks of PM lesion vs healthy peritoneum with the AUC values of the most discriminative peaks. B 3-dimensional plot of PCA scores of inter-patient mass spectra peaks originating from healthy peritoneum and tumor tissue. A percentage explaining the variance between samples is shown. C MS spectra from normal peritoneal tissues from six PM patients. D The peak intensities distributions in solubilized PT21_19N tissue are depicted through box plots that match m/z values of certain STs (778.5, 794.5, 904.6, 906.6) and PI 38:4 (885.6)
