Abstract BACKGROUND: We examined CEACAM6, ITGB1, and cyr61 concentrations from patients with gastric cancers (GCs) to assess their clinical application for diagnosing and monitoring diseases. METHODS: Real-time reverse transcription-polymerase chain reaction was used to detect the expressions of CEA, CEACAM6, ITGB1, IGF1R, CK20, cyr61, and S100A4 in peripheral blood karyocyte from 82 patients with GC, 24 patients with recurrence, and 37 healthy volunteers. Receiver operating characteristics (ROC) curves were constructed. RESULTS: There were significant association between these CEACAM6, ITGB1, and cyr61 and TNM Stages and distant metastasis. The AUC of CEACAM6 was 0.884 ± 0.044 (P = 0.0001), the AUC of cyr61 was 0.833 ± 0.047 (P = 0.0001), and the AUC of ITGB1 was 0.838 ± 0.042 (P = 0.0001) by differentiating preoperative GC patients from healthy volunteers from ROC curve analysis. The AUC of CEACAM6 was 0.761 ± 0.066 (P = 0.001), the AUC of CYR61 was 0.762 ± 0.063 (P = 0.001), and the AUC of ITGB1 was 0.824 ± 0.051 (P = 0.0001), by differentiating recurrence of GC from healthy volunteers from ROC curve analysis. CONCLUSION: The method of detecting the expression of CEACAM6, ITGB1, and CYR61 in peripheral blood of GC patients was more sensitive than CEA, IGF1R, CK20, and S100A4 for the early diagnosis of metastasis and recurrence.
