Objectives: To give a description of clinical characteristics of brain magnetic resonance image in patients with brain metastases from non-small cell lung cancer. Subjects and method: A prospective study on 104 patients with brain metastases from non-small cell lung cancer, from 2-2017 to 9-2018. | Journal of military pharmaco-medicine no1-2019 STUDYING CLINICAL CHARACTERISTICS OF BRAIN MAGNETIC RESONANCE IMAGE IN NON-SMALL CELL LUNG CANCER PATIENTS WITH BRAIN METASTASES Nguyen Minh Hai1; Nguyen Dinh Tien1; Pham Van Luan1 SUMMARY Objectives: To give a description of clinical characteristics of brain magnetic resonance image in patients with brain metastases from non-small cell lung cancer. Subjects and method: A prospective study on 104 patients with brain metastases from non-small cell lung cancer, from 2 - 2017 to 9 - 2018. Results: Mean age was 59, most of them under 65 years old (), male occupied , adenocarcinoma . EGFR (+) . Asymptomatic patients explained . Size of brain metastases ≤ 2 cm made up , 1 - 2 tumors constituted . Conclusion: Most patients with brain metastases from non-small cell lung cancer were males, under 65 years old with adenocarcinoma and asymptomatic histology. Size of brain metastases ≤ 2 cm and 1 - 2 tumors in brain were common. Brain metastases with ring enhancement was , peritumoral edema was . * Keywords: Non-small cell lung cancer; Brain metastases; Brain magnetic resonance image; Clinical characteristics. INTRODUCTION Lung cancer remains a leading cause of mortality with million deaths worldwide. An estimated 234,030 new cases occurred in the United States in 2018 with a median age at diagnosis of 70 and 64% of predominance for males. Approximately 84% of these lung cancers are non-small cell lung cancers (NSCLC). Despite improvements in systemic therapy, the survival rate for patients with stage IV disease is poor, with fewer than 5% of 5-year survival after diagnosis. The frequency of central nervous system involvement in NSCLC patients is reported to reach 40% and 25% to 30% of NSCLC patients have synchronous brain metastases (BMs) at the time of diagnosis [5, 8]. The recent, widespread use of magnetic resonance image (MRI) has led to the increased identification of .
