Summary
Brief summary (as posted)
The goal of this mutli-center observational study is toinvestigate the impact of primary tumor resection (PTR) on the long-term survival of patients with non-small-cell lung cancer (NSCLC) and dry pleural dissemination (DPD). The main question it aims to answer is: whether primary tumor resection improve long-term survival of NSCLC patients with dry pleural dissemination.
