Abstract:
Objective Statistically analyze the serum P53 antibody level in lung cancer patients to show its diagnostic values.Methods 53 cases of lung cancer and 32 cases of lung cancer after operation and chemotherapy are used as study group. 34 normal controls and 35 cases of lung benign disease were used as control group. All the serum P53 antibody levels of the testees are measured with a ELISA kit.Results In 53 cases of lung cancer group, the positive rate was 58.5% (31/53), while the average serum P53 antibody level was (4.551?6.074)IU/ml. In 32 cases of lung cancer after treatment including surgical and medical procedures, the positive rate was 25% (8/32), while the average serum P53 antibody level was (1.086?2.836)IU/ml. In 35 cases lung benign disease group, the average serum P53 antibody level was (0.163?0.097)IU/ml. In normal group, the average serum P53 antibody level was (0.162?0.08)IU/mL.The lung cancer group had statistical significance in comparison with the other three groups (P0.05).Conclusion The P53 antibody′s appearance is highly correlated with lung cancer. It can be used as an important marker of lung cancer and be beneficial to the differential diagnosis of lung lesions and the evaluation of the treatment.
