Abstract:
Objective To determine the effects of pre-operative chemotherapy on p53 expression and apoptosis in lung cancer.Methods 42 patients with lung cancer were divided into pre-opreative chemotherapy group (n=14) and control group (n=28) without preoperative chemotherapy.Method of immunohistochemistry was used to detect the expression of p53 . Terminal deoxynucleotidyl transferase nick end labeling (TUNEL) was used to detect the apoptotic cells.Results The positive rate of p53 expression were as follows;53 5% for control group,64 3% for prechemotherapy group,64 3% for postchemotherapy group respectively;the apoptosis indexes were 6 3?1 9 for control group,7 3?1 6 for prechemotherapy group,14 5?4 6 for postchemotherapy group.Conclusions The preoperative chemotherapy can induce apoptosis in lung cancer ,but can not affect p53 expression .
