Résumé

Objective To explore the role of cell cycle regulators in tuberculosis with lung carcinoma.Methods p53,MDM_2,p21~ ras and p21~ WAF1 proteins were detected by LsAB immunohistochemical technique in 69 cases of tuberculosis with lung carcinoma.Results As compared with primary tuberculosis with lung carcinoma,the expression rate p53 or MDM_2 protein in relapsing NPC was similar(78% to 80%,84% to 83%),and the expression rate of p21~ ras and p21~ WAF1 protein in relapsing NPC was obviously descended(73% to 93%,52% to 84%);The high-expression rate of p53 protein in relapsing NPC was similar(42% to 51%),the high-expression rate of MDM_2 protein in relapsing NPC was obviously risen(57% to 32%),and the high-expression rate of p21~ ras and p21~ WAF1 protein in relapsing NPC was obviously descended(16% to 65%,17% to 46%).Among of them,the significant rise of MDM_2 protein expression level in relapsing NPC mainly occurred in the patients of group 2 which relapsing-interval was shorter than 34 months(P

Résumé

Objective To explore the role of cell cycle regulator in tuberculosis with lung cancer.Methods The ex- pression of p21~(WAF1)gene and p53 protein in 101 cases of tuberculosis with lung cancer have been detected by immunohis- toehemical method.Results total positive staining rate of p21~(WAF1)gene and p53 protein was 42.9% and 64.1%; The expression of both was correlated with histological classification and differentiation of carcinoma.Conclusion Detection of p21W AF1 gene and p53 protein expression may have significant value in the prognosis of tuberculosis with lung cancer
