This book titled “Oligometastatic Lung Cancer” is a collection of articles contributed by renowned experts in this field from leading centers of excellence around the world and it provides a comprehensive review of various aspects of oligometastatic NSCLC. There are three main sections, including research status, epidemiology, and treatment of oligometastatic NSCLC. In the first section, the authors cover various aspects of clinical and translational research in eight articles. The second section includes an article on the epidemiology of oligometastatic NSCLC based on a systematic review and pooled analysis. The last section is further divided into subsections including surgery, ablative therapy, radiotherapy, and ablative radiotherapy, immunotherapy, and local consolidative therapy. The five articles in the surgery subsection cover the evidence for surgery for oligometastatic NSCLC, appropriate surgical candidate selection, surgical approaches, the surgeon’s role in oligometastatic NSCLC, and clinically prognostic factors in surgically treated patients, respectively. The next section on ablative therapy includes three articles with one editorial on ablative therapy for oligometastatic NSCLC. The other two articles are narrative reviews on local ablative therapy for oligometastatic NSCLC and local ablative therapy for oncogenic driven oligometastatic NSCLC, respectively. In the radiotherapy section, there are two articles covering the role and the changing landscape of radiotherapy in oligometastatic NSCLC. Subsequent section on ablative radiotherapy includes four articles covering the role of SBRT in oligometastatic NSCLC including for consolidation. The section on immunotherapy includes an article on the optimization of immunotherapy in trials for oligometastatic NSCLC.
