A Review of the Progress in the Diagnosis and Treatment of Pulmonary Sarcomatoid Carcinoma

Pulmonary sarcomatoid carcinoma (PSC) is a rare pathological type of non-small cell lung cancer that combines the characteristics of epithelial and mesenchymal tumors and is an extremely malignant and highly heterogeneous malignant tumor. PSC is difficult to diagnose and has a poor sensitivity to radiotherapy. In recent years, with the efficacy breakthroughs of molecularly targeted drugs and immune checkpoint inhibitors in tumor therapy, the treatment of PSC is gradually exploring precise targeted therapy and immunotherapy. In this article, we will provide a comprehensive review of the clinical features, diagnostic points, and progress in the clinical therapeutic research of PSC. We hope to provide guidance and help with clinical treatment and scientific research.
