Radiologic Complete Response In Lung Adenocarcinoma With Symptomatic Brain Metastasis After Systematic Therapy: A Case Study

Patients diagnosed as lung adenocarcinoma with brain metastasis usually result in poor prognosis with limited survival time. Palliative systematic therapy has emerged as the primary choice for non-small cell lung cancer patients with brain metastasis harboring wild-type drive genes. However, the objective response rate and long-term survival for patients treated with this therapy remained unsatisfied. Herein, we present a case with lung adenocarcinoma accompanied with symptomatic brain metastasis who achieved radiologic complete response after receiving combined therapy including stereotactic body radiation therapy, anti-angiogenesis, and chemotherapy. He has achieved a duration of disease-free survival of thirty-six months, and is still in extension.
