Abstract:
Purpose:To study the relation between regional lymph node metastasis and nm23 H 1 protein expression and DNA ploidy of esophageal squamous cell carcinoma patients. Methods:Flow cytometry was used to analyze nm23 H 1 protein and DNA ploidy in surgical specimens from the patients with esophageal carcinoma. The object tissues included: the primary tumor tissue, the pericancerous mucosa, the incisional margin and the regional lymph node. Results:There were obvious differences between nm23 H 1 protein expression in lymph node metastasis positive and negative groups, primary tumor tissue and pericancerous mucosa, cancer tissue and the incisal margin( P 0.05).The differences of DI were distinct between cancer tissue and the pericancerous mucosa, cancer tissue and the incisal margin, cancer tissue and the lymph node( P 0.05).In corresponding tissues of lymph node metastasis positive and negative groups, nm23 H 1 protein expression was different( P 0.05). As to DI, it was different only among pathological grades( P 0.05). Conclusions:nm23 H 1 protein higher expression can produce certain inhibitory effect on metastasis of esophageal carcinoma. Combining DNA ploidy detection can help to understand the biological behavious and deduce the prognosis of esophageal carcinoma.
