Here, we conducted the study to evaluate the impact of PTB on survival of Chinese EGFR mutant lung adenocarcinoma (LUAD) patients that underwent EGFR-TKI treatment.Methods: Clinicopathologic data of 1448 LUAD patients harboring EGFR mutations from the Guangzhou Chest Hospital between 2017 and 2019 were reviewed retrospectively. Patients receiving EGFR-TKI treatment were divided into PTB and non-PTB groups. The differences in response to EGFR-TKIs and survival between the two groups were assessed.Results: After EGFR-TKIs treatment, the objective response rate (58.14% vs 47.62%) as well as disease control rate (97.67% vs 85.71%) were higher in the non-PTB group than in the PTB group, but there was no statistical difference. In the survival analysis, both the median progression-free survival (7.47 months vs 11.77 months, p = 0.038) and the overall survival (13.00 months vs 20.00 months, p = 0.001) were significantly shorter in the PTB group than in the non-PTB group. Furthermore, for patients with 19Del mutation, or metastases sites less than 3, or using first-line EGFR-TKI, EGFR-TKIs treatment significantly prolonged the median PFS and OS in patients without PTB.Conclusion: LUAD patients with concomitant PTB have a poor response to EGFR-TKI treatment, especially in terms of survival outcome.Keywords: advanced lung adenocarcinoma, pulmonary tuberculosis, EGFR mutation, EGFR-tyrosine kinase inhibitors, prognosis
