The study focuses on the importance of detecting EGFR and KRAS mutations in lung cancer patients before starting targeted drug therapy.
Using Real-time PCR on fine needle aspiration cytology samples from metastasized lymph nodes, researchers found an EGFR mutation rate of 37.3% and KRAS mutation rate of 7.2%.
Clinical follow-up showed that patients with identified mutations responded well to treatment, with a significant portion achieving complete or partial remission.
