目的 :探讨微量元素 Zn与食管癌的关系。方法 :用原子吸收分光光度计对食管癌组织中微量元素锌的含量进行测定。结果 :食管癌组织中 Zn含量明显低于癌旁正常食管组织和正常人食管组织中 Zn的含量 ,恶性程度高和有淋巴结转移的食管癌组织中 Zn含量明显降低。结论 :食管癌组织中 Zn含量的测定能反映食管癌的生物学行为 ,并能估计预后。
Objective: To explore the relationship between trace element Zn and esophageal cancer. Methods: The content of zinc in esophageal cancer tissue was determined by atomic absorption spectrophotometer. Results: The Zn content in esophageal cancer tissue was significantly lower than that in normal esophageal tissue and normal esophageal tissues. The Zn content in esophageal cancer tissues with high degree of malignancy and lymph node metastasis was significantly reduced. Conclusion : The determination of Zn in esophageal cancer tissue can reflect the biological behavior of esophageal cancer and can estimate the prognosis.
