Non-small-cell lung cancer (NSCLC) patients with dry pleural dissemination have poor survival rates and are generally contraindicated for surgery. Previous single-center retrospective studies have suggested that these patients may benefit from primary tumor resection (PTR). However, the evidence supporting PTR is still limited, especially in the era of targeted therapy. This study aimed to investigate the impact of PTR on the long-term survival of patients with NSCLC and DPD.
