Abstract

Objectives: To evaluate the results of the first-line therapy after the first-generation tyrosine kinase receptor inhibitors (TKIs) in female patients with non-small cell lung cancer (NSCLC) stage IIIB-IV. Subjects and methods: Regression study on 75 female patients with NSCLC stage IIIB-IV, harboring EGFR mutation, received 1st generation TKIs as first-line treatment at Bach Mai hospital from 2019-2021. Results: Partial response rate 76%, no patient had complete response. Disease control rate is 93,3%. Response to brain damage 59,1%. The response was higher in the group having the adverse event in the skin with both gefitinib and erlotinib (statistically significant). Prolonged progression-free survival was 12,5±0,6 months, median of 12 months. The prolonged progression-free survival median of two groups using gefitinib and erlotinib as first-line treatment is non statistical significance. The independent factors that have a good influence on prolonged progression-free survival are the whole state just before treatment: the ECOG PS value 0-1, the exon 19 mutation and adverse events in the skin (rash). Common adverse events were rash and diarrhea, the majority I and II. The rates of treatment discontinuation and dose reduction due to low toxicity were 2,7% and 1,3%.
