Circulating peripheral blood CD14+/CD16+ monocyte-derived macrophages (MDMs) were evaluated in OSCC patients with oral squamous cell carcinoma (n = 44) compared with controls (n = 85). Moreover, epitope detection in monocytes (EDIM) technology was used to detect biomarkers Apo10 and transketolase-like-1 in CD14+/CD16+ MDMs.
Compared with controls, no significant (P = .3646) difference (control group 9.8%, OSCC group 8.8%) in CD14+/CD16+ MDM were noted in OSCC. However, EDIM-Apo10 and EDIM-TKTL1 scores detected in the CD14+/CD16+ MDMs were increased in OSCC compared with controls (P < .0001).
Analyzing CD14+/CD16+ MDMs represents a stable cell population for detecting biomarkers in cancer disease monitoring.
