AIM: To evaluate the clinical value of serum high mobility group box chromosomal protein 1 (HMGB1) levels in making the early diagnosis of recurrent cervical squamous cell carcinomas (CSCC) and compare it with the value of serum squamous cell carcinoma antigen (SCCA), cytokeratin fragment (CYFRA) 21-1, and carcinoembryonic antigen (CEA) levels. METHODS: Immunohistochemical staining of tissue from 64 patients with recurrent CSCCs, 72 patients with non-recurrent carcinoma, and 28 healthy participants was performed to determine the expression of HMGB1 protein. The serum levels of the 4 markers in 112 patients with recurrent CSCC, 174 patients with non-recurrent disease, and 128 healthy participants were measured by enzyme-linked immunosorbent assay. The receiver operating characteristic (ROC) curves were constructed and the area under the curve (AUC) was calculated. RESULTS: Higher immunostaining score was found in recurrent CSCC tissue sections than in non-recurrent CSCC sections. Serum HMGB1 levels in patients with recurrent CSCC were significantly higher than in patients with non-recurrent disease and healthy controls. The AUC of HMGB1, SCCA, CYFRA21-1, and CEA was 0.816, 0.768, 0.703, and 0.625, respectively. HMGB1 had the best specificity and positive likelihood ratio (78.0% and 3.25, respectively), whereas SCCA had the best sensitivity and negative likelihood ratio (76.3% and 0.34, respectively). Parallel combined measurements increased the diagnostic sensitivity and serial combination increased the specificity. High serum HMGB1 levels were inversely correlated with disease-free survival (P=0.009, Pearson chi(2) test) and overall survival (P=0.018). CONCLUSION: HMGB1 was overexpressed in recurrent CSCCs. Serum HMGB1 level could be a useful and specific marker for evaluating the disease recurrence and predicting prognosis in patients with CSCC. Serial combined measurements of serum HMGB1, SCCA, and CYFRA21-1 increased the diagnostic specificity, and parallel combined testing increased the diagnostic sensitivity.
