OBJECTIVE: The aim of this study was to compare TFF3, AIF-1, S100-A11 and DKK1 serum levels in patients with cervical dysplasia, and in healthy female controls. METHODS: The first group included 59 patients with a histological dia-gnosis of precancerous disease CIN 1. The second group included 198 patients with a histological dia-gnosis of precancerous disease CIN 2 or CIN 3. The control group was comprised of 90 patients who underwent elective total hysterectomy for nonmalignant disorders. In all patients, preoperative serum samples were taken and separated; the sera were all stored at -80°C until the analysis for TFF3, AIF-1, S100-A11 and DKK1. RESULTS: The serum levels of S100–A11 (P < 0.0001) and AIF-1 (P < 0.0001) were statistically significantly higher in patients with mild precancerous lesions (CIN 1) than in controls. The levels of TFF3 and DKK1 were not statistically significantly different in patients with CIN 1 and in the control group. The serum levels of S100–A11 (P < 0.0001) and AIF-1 (P < 0.0001) were statistically significantly higher in patients with severe precancerous lesions (CIN 2/3) than in controls. TFF3 and DKK1 levels were not statistically significantly different in patients with CIN 2/3 compared to controls. CONCLUSION: S100-A11 and AIF-1 represent potential bio-markers in patients with cervical dysplasia.
