    Abstract:
    OBJECTIVE: To study the clinical significance of serum CEA, SCC and Cyfra21-1 test in the diagnosis, prediction of prognosis and postoperative monitor of recurrence in esophageal cancer. METHODS: The concentration of serum CEA and Cyfra21-1 was measured by electrochemiluminescence immunoassay (ECLIA) using Elecsys 2010, CEA kit and Cyfra21-1 kit. Serum SCC was measured by microparticle enzyme immunoassay (MEIA) using IMx System and SCC kit. Serum of 206 patients with esophageal cancer (203 squamous cell carcinoma, 2 small cell carcinoma and 1 adenosquamous carcinoma) was measured preoperatively, 71 of whom also measued 8 to 12 days after resection. RESULTS: The cut-off value of CEA and Cyfra21-1 was < or = 3.25 ng/ml and < or = 2.61 ng/ml, which were determined by the data of 45 healthy Chinese measured during the same period. The positive ratios of serum CEA and Cyfra21-1 in 206 cases were 29.1% and 45.1%. The combined positive ratio of CEA and Cyfra21-1 was 57.3%. The CEA positive ratios, according to the pathological stage of 165 resectable patients, were 16.6% (stage I), 26.8% (II) and 30.8% (III). For Cyfra21-1, they were 27.8%, 37.5% and 50.5%. For CEA combined with Cyfra21-1, they were 38.9%, 50.0% and 63.7%. The mean value of CEA, SCC and Cyfra21-1 (especially SCC and Cyfra21-1) was found to be well correlated with the tumor volume, TNM stage and depth of tumor invasion. Patient with bulky tumor or advanced tumor (T4) usually had much higher mean value than those with early stage tumors. One week after radical resection, the level of the three tumor markers fell to normal level in 92.9% of 71 patients. The level of serum CEA and Cyfra21-1 varied greatly in a small part of the patients. Extremely elevated serum CEA and Cyfra21-1 usually indicated advanced lesion or tumor metastasis. CONCLUSION: Preoperative and postoperative measurement of serum CEA, SCC and Cyfra21-1 (especially Cyfra21-1) is helpful in the diagnosis, prediction of prognosis and monitor of postoperative recurrence in patients with esophageal cancer.
