E-钙黏蛋白在鼻咽癌组织中的表达水平及其与颈部淋巴结转移的关系

Objective To investigate the expression of E-cadherin in nasopharyngeal carcinoma ( NPC) and its relationship with cervical lymph node metastasis. Methods The expression of E-cadherin in 80 patients with NPC was detected by immunohistochemistry. Results Lower expression of E-cadherin was associated with advanced N-stage of the tumor ( P = 0. 018 ). There was no significant correlation between the expression of E-cadherin and lymph node size ( P = 0.435 ). The expression of E-cadherin was higher in patients with cervical lymph node metastasis limited to a single area than that distributing in some scattered areas (P = 0. 000). There was a trend that the expression of E-cadherin in the cases with the tumor and lymph nodes in the same side was higher (56. 5% ) than that in the patients with bilateral lymph node metastases (32. 6% ) , however, the difference was not significant (P =0. 059). The expression rates of E-cadherin in patients with lymph node metastasis in levels Ⅱ , Ⅲ and Ⅴa were higher than that in levels Ⅰ , Ⅳ, Vb and Ⅵ, but with a non-significant difference (P = 0.059). Conclusion The expression of E-cadherin has influence on the lymph node metastasis in nasopharyngeal carcinoma. E-cadherin expression is negatively correlated with the numbers of the lymph node metastases and the metastasis distance, i. e. a lower expression of E-cadherin leads to an advanced N-stage. The lymph node metastasis of nasopharyngeal cancer from above to below is more considerably influenced by E-cadherin expression than the metastasis towards contralateral lymph nodes.

Objective To approach the relationship between the expression of hK6 in ovarian neoplasm and clinicopathological variables and prognosis in ovarian cancer patients for finding a new tumor marker of the ovarian cancer. Methods The expression of hK6 was detected by immunohistochemistry in 19 cases of benign, 11 cases of borderline and 45 cases of malignant ovarian neoplasms and statistically analyzed whether its expression correlate with clinicopathological variables and prognosis in patients with ovarian cancer. Results The expression of hK6 in ovarian cancer tissues (60.0%) was significantly higher than that in the benign (15.8%) and borderline (27.3%) ovarian neoplasm tissues (P < 0.01). The expression of hK6 in higher-grade ovarian cancer tissues (68.4%) was higher than that in low-grade ones (14.3%, P<0.05). The expression of hK6 in late-stage (stage Ⅲ ,76.7%) was significantly higher than that in early-stage (stage Ⅰ or Ⅱ ,26.7%, P < 0.01). The expression of hK6 was significantly higher in patients with lymph node metastasis (77.8%) than that in patients without (33.3% ,P<0.01). The expression of hK6 in the cancer tissues in the patients died, or with reeeurence or metastasis within 3 years after surgery was higher (75.0%) than that in the patients with stable disease (42.9%, P < 0. 05). Conclusion The expression of hK6 in ovarian cancer was higher than that in benign and borderline ovarian neoplasms. The expression of hK6 is higher in the ovarian cancer of late stage, higher-grade, with lymph node metastasis and is associated with a poorer prognosis, hK6 may become a new markers in prediction of prognosis of the patients with ovarian tumors.
