Case report: Radiotherapy plus pneumococcal conjugate vaccine stimulates abscopal immune response in a patient with NSCLC.

Most patients with anaplastic lymphoma kinase-positive () non-small-cell lung cancer (NSCLC) could benefit from the treatment with selected tyrosine kinase inhibitors (TKIs) for a period of time, but almost inevitably progress due to drug resistance. It was reported that these patients were generally unresponsive to immune-based therapies. Here, we reported that stereotactic body radiotherapy (SBRT) combined with pneumococcal conjugate vaccine (PCV) produced excellent therapeutic outcomes in a patient after multiple lines of TKI treatment.
