GC-MS was utilized to analyze the metabolites in both the in vivo and in vitro experimental groups. In vivo, we analyzed VOCs in the blood of mice at 2, 4, 6, and 8 days after cell inoculation and on days 10 and 12 after tumor resection. We analyzed these variables based on the ion peaks in the resulting chromatogram and then evaluated their performance as predictors of CRC. In vitro experiments were performed by comparing changes in VOCs in HCoEpiC cells, the control group, the SW620 cell group, and the ATO+SW620 group.
