Neoadjuvant therapy refers to preoperative adjuvant treatment based on the experiences of successful postoperative adjuvant treatment. The neoadjuvant therapy, which aims at increasing the possibility of cancer resection and improving patients survival, includes neoadjuvant chemotherapy, neoadjuvanl radiother-apy and neoadjuvant chemoradiation. Neoadjuvant chemoradiation may be the preferred neoadjuvant modality to increase resection rate and improve survival rate in patients with locally advanced esophageal cancer.

Objective To explore the clinical significance of epithelial cellular adhesion molecule (Ep-CAM)expression in esophageal carcinoma.Methods Ep-CAM expression of in 60 cases of esophageal carcinoma、35 cases of atypical hyperplasia and 35 cases of normal esophageal mu-cosa was respectively examined by immunohistochemistry.Results Ep-CAM expression were ob-served with positive in 28.75% of atypical hyperplasia and 90.00% of esophageal carcinoma,but with no positive expression in normal esophageal mucosa.The Ep-CAM expression with positive were significantly differently between degrees of tumor differentiation(P <0.01),lymphatic metas-tasis and 3-year survival(P <0.05).Conclusion The increase of Ep-CAM expression,as a specific index,may has the potential for esophageal cancer diagnosis and prognosis.
