Comparison of preoperative OSCC patients with healthy controls. The heat map shows 25 areas of interest in 10 patients with OSCC (a), 10 healthy controls (c) and correlations with the room air of OSCC patients (b) in positive drift mode. Area 6 is significantly more pronounced in OSCC patients than room air, therefore, the endogenous origin of analytes can be assumed and may be associated with OSCC. In contrast, the signal observed in Area 8 is significantly increased in room air samples, an external origin of analytes is likely. The greatest signal intensity within Area 13 was observed for samples taken from the healthy control group
