Article Abstract

Introduction: Patients with non-small cell lung cancer (NSCLC) and brain metastatic disease have an unfavorable prognosis. The goal of the treatment in stage IV NSCLC is to increase the survival rate and to improve the quality of life.

Case Report: We present the case of a young male patient (47 years old at the time of diagnosis in 2021) with NSCLC stage IV with the onset of the disease through neurological symptoms determined by brain metastasis. The immunohistochemical result raised problems of differential diagnosis. The complete favorable response was obtained 20 months after the initiation of second-line immunotherapy, maintaining this response 6 months later.

Discussion: The therapeutic approach for the second-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) without mutations has been revolutionized by the approval of immune-checkpoint inhibitors (ICIs). The combination of radiotherapy and immunotherapy can increase the abscopal phenomenon by the stimulation of an immune response against tumors at distant sites, outside the radiation field, as recent studies suggest.

Conclusions: Second-line immunotherapy is beneficial to the survival of patients with NSCLC with disease progression beyond initial chemotherapy. The combination of radiotherapy and immunotherapy has the potential to play an important role in metastatic NSCLC.
