摘要: Background. The p53 gene is frequently mutated in non-small-cell lung cancer (NSCLC). However, the effect of mutations on patient prognosis remains unclear. Aim. aim this study to determine association abnormalities with clinical data and patients NSCLC. Material Methods. Tumor tissues from 80 NSCLC were assessed by immunohistochemistry for expression p53. immunohistochemical was performed formalin-fixed, paraffin-embedded sections using LCAB immunoperoxidase method mouse anti-p53 monoclonal antibody (clone DO-7; DAKO). Results. Forty-three (53,75%) revealed aberrant immunostaining Except histological type tumors, there no correlation clinicopathologic features. Kaplan-Meier survival analysis demonstrated that positive status had poor rate (p=0,005 Log Rank test= 7,914). In Cox, regression performance emerged as independent prognostic factors (p<0,009 p<0,000 respectively). Conclusion. results indicated significant predictable factor
