Personalized lung cancer therapy has progressed by targeting several oncogenic aberrations that drive lung carcinogenesis. Recent advances in gene analysis technologies, including next-generation sequencing that yields large amounts of genomic data, have greatly contributed to this progress. In addition, immune checkpoint blockade therapy has become available in Japan, and extensive searches for biomarkers predictive of therapeutic response have been carried out. "Clinical sequencing" which analyzes aberrations in a set of therapy-related genes in patient cancer specimens, has been actively conducted in Japan and other countries. This will help to establish more efficient and effective precision cancer medicine based on gene information. Herein, we summarize the recent progress in personalized lung cancer therapy research, including clinical sequencing.
