EGFR GENE MUTATION STATUS IN STAGE III AND IV NON-SMALL CELL LUNG CANCER PATIENTS AT THANH HOA ONCOLOGY HOSPITAL IN 2023-2024
Main Article Content
Abstract
Lung cancer is one of the most common types of cancer in Vietnam, with non-small cell lung cancer (NSCLC) being the most prevalent histological type, accounting for up to 80%. Targeted therapies using TKI have been confirmed to be effective in patients with EGFR mutations. However, the level of effectiveness, response, or resistance to different generations of TKI depends on the type of EGFR mutation. Therefore, testing for EGFR mutations in patients plays an important role in prognosis and treatment. Objectives: 1. To determine the rate of EGFR gene mutations of stage III-IV NSCLC patients. 2. To evaluate the relationship between certain clinical characteristics and EGFR gene mutation status in the study group. Subjects and research methods: A descriptive study of 219 stage III-IV NSCLC cases was conducted with EGFR gene mutation testing performed at Thanh Hoa Cancer Hospital from November 2023 to August 2024. Results: The EGFR mutation rate in the study was 29.7%. Exon 19 (Del19) and exon 21 (L858R) were the most commonly found mutations. Females had a 5.744 times higher risk of EGFR mutation compared to males. Non-smokers had a 6.407 times higher risk of EGFR mutation compared to smokers. Conclusion: The EGFR mutation rate in this study is lower than in most domestic studies. The relationship between EGFR mutation status and clinical characteristics observed at Thanh Hoa Cancer Hospital aligns with many studies in Vietnam and globally.
