Background: EGFR mutation is a genetic disorder that is often observed and examined in Non-Small Cell Lung Carcinoma. EGFR mutation detection aims to predict sensitivity to EGFR-TKI and acts as first-line therapy. Targeted therapy with EGFR-TKI can increase the survival rate of patients with Non-Small Cell Lung Cancer compared to chemotherapy. This study aims to obtain data on the survival rate of patients with Non-Small Cell Lung Carcinoma who received targeted therapy at H. Adam Malik Hospital. 

Methods: This study is a descriptive study with a retrospective cohort design carried out at the Oncology Polyclinic at RSUP H Adam Malik Medan for 5 years, from January 2014 to December 2018. The subjects of this study were all patients with lung cancer type adenocarcinoma who had received therapy with generation 1 or 2 EGFR TKI. 

Results: 99 patients were included as subjects of this study. From the study, the most influential factors on lung cancer were gender, age, and smoking addiction. The study consisted of 60.6% male, 92.9% of the respondents aged 40 years and over, 56.5% active, and 43.4% passive smokers and 41.4% of the respondents with severe Brinkman index. The 30-month survival rate of EGFR-TKI (Gefitinib) patients treated with NSCLC Adenocarcinoma (Gefitinib) from 2014 to 2018 at H. Adam Malik Hospital Medan was 6.3% with a median survival of 7 months. The duration of progression-free survival in patients receiving Erlotinib therapy was 6.6 months (6.6 ± 2.51 months), while the length of progression-free survival for patients treated with Gefitinib was 9.1 months (9.1 ± 6.9 months). The results of statistical tests showed that there was no difference in progression-free survival rate between those who received Erlotinib and Gefitinib (P = 0.82). 

Conclusion: The 30-month survival rate of lung adenocarcinoma patients treated with EGFR-TKI from 2014 to 2018 was 6.1% with a median survival of 7 months. Those who received Erlotinib therapy experienced Progression-Free Survival for 6.6 months and those who received Gefitinib experienced Progression-Free Survival for 9.1 months.
