Core Tip

Core tip: In recent years, numerous studies, including two randomized phase II trials, have demonstrated that local treatment, either radiotherapy or surgery, of the primary tumor and metastases improves progression-free survival and overall survival in patients who present with oligometastatic non-small cell lung cancer at diagnosis and in those who respond to the initial systemic therapy. As we await the results of ongoing randomized phase III trials, the main international clinical guidelines recommend a multimodal strategy to manage this subgroup of oligometastatic patients. Current guidelines recommend systemic therapy combined with local treatment of the metastases and, if applicable, the primary tumor.
