ABSTRACT
<p><b>OBJECTIVE</b>To explore the level of serum high-mobility group box 1 (HMGB1) in patients with esophageal squamous cell carcinoma (ESCC) and the feasibility of HMGB1 as a tumor marker.</p><p><b>METHODS</b>Serum HMGB1, carcinoembryonic antigen (CEA), cytokeratin 19 fragment antigen (Cyfra21-1) and squamous cell carcinoma antigen (SCC) were measured by enzyme-linked immunosorbent assay (ELISA), electrochemiluminescence immunoassay (ECLIA) and microparticle enzyme immunoassay (MEIA) respectively in 78 patients with ESCC preoperatively as well as a month after esophagectomy. At the same time, serum HMGB1, CEA, Cyfra21-1 and SCC of 60 healthy adult volunteers were detected with the same method. The unilateral P95 value of serum HMGB1 (>96 μg/L) was defined as positive. According to the Roche kit diagnostic criteria, CEA>5.0 μg/L, Cyfra21-1>3.3 μg/L and SCC>1.5 μg/L were defined as positive.</p><p><b>RESULTS</b>The preoperative positive ratio of serum HMGB1 in 78 patients with ESCC was 84.6%, and the level of serum HMGB1 was associated with the tumor size, infiltration depth, lymph node metastasis and tumor stage (P<0.01 or P<0.05). One month after esophagectomy, the level of serum HMGB1 in ESCC declined significantly compared with the preoperative level (P<0.01), and the level of serum HMGB1 in T4, N1, stage III was higher compared to corresponding T, N and tumor stage (P<0.01 or P<0.05). The positive ratio of CEA, Cyfra21-1 and SCC was 10.3%, 25.6% and 42.3% respectively in 78 ESCC patients preoperatively, so the sensitivity of these tumor markers was lower. One month after esophagectomy, serum Cyfra21-1 and serum SCC were significantly decreased compared to the preoperative level (P<0.01). However, there was no significant difference of preoperative serum CEA compared to a month after esophagectomy in ESCC (P>0.05). The specificity of HMGB1, CEA, Cyfra21-1 and SCC were 93.3%, 88.3%, 90.0% and 93.3% respectively.</p><p><b>CONCLUSION</b>Compared to CEA, Cyfra21-1 and SCC, serum HMGB1 in ESCC patients is easier for detection and its sensitivity and specificity are higher, which may be used as a marker in diagnosis, prediction of prognosis and monitor of postoperative recurrence of ESCC.</p>
