A Study on Relation ship between Tumor Cell Proliferation, Apoptos is and Prognos is in Patients with Primary Lung Cancer

Objective To investigate the relationship between cell proliferation,apoptosis and prognosis in primary lung cancer patients. Methods The expression of Ki 67 were detected by immunohistochemistry,and the apoptosis level were assessed by TUNEL. Results (1) The Ki 67 index(KI) in lung cancer tissues was closely related to histological classification and cancer cell differentiation,and the apoptosis index(AI) is significantly related to P TNM stages,lymph node involvement;(2) The postoperative survival time i...
