TP53 and non-small cell lung carcinoma: The results showed that the expression of P53 protein in NSCLC patients with BMS was significantly higher than that in NSCLC patients without BMS, and the analysis of P53 protein by the ROC curve had higher predictive value for the occurrence of BMS in NSCLC patients, confirming the high efficacy of P53 protein expression in predicting the prognosis of patients.
