[Non-Small Cell Lung Cancer]

Oligometastases(Oligo-meta)were first defined in breast cancer, and the criteria are a small number of metastases and the possibility of local treatment for all lesions. It has been pointed out that the addition of local therapy to standard therapy may prolong survival in the treatment of Oligo-meta, and the same is possible in non-small cell lung cancer(NSCLC). Since NSCLC can metastasize to various organs, local treatment options for Oligo-meta differ depending on the metastatic organ. Therefore, when treating Oligo-meta in NSCLC, multidisciplinary treatment is necessary, considering various conditions such as patient background and metastatic sites, and in collaboration with various departments. In recent years, the mainstay of treatment of NSCLC has shifted to immune checkpoint inhibitors. The treatment of Oligo-meta in combination with these drugs may enhance the therapeutic effect. Several clinical trials are currently underway for the treatment of Oligo-meta in NSCLC, combining local therapy with immune checkpoint inhibitors, and we look forward to the results of these trials.
