Detailed Description

Pulmonary sarcomatoid carcinoma(PSC) is a rare primary lung cancer, which belongs to the category of non-small cell lung cancer(NSCLC), accounting for about 0.3%-1.3% of lung cancers .Platinum-based combination chemotherapy is the standard adjuvant chemotherapy and palliative chemotherapy for NSCLC, and it is also commonly used for PSC. Advanced PSC has a low response rate to systemic chemotherapy and a short duration of curative effect. The primary progression rate of aggressive platinum-based chemotherapy is 60%-70%, showing that PSC is highly resistant to multiple chemotherapeutics. In recent years, the progress of targeting MET tyrosine kinase mutations has been relatively rapid, but most of the mutant PSCs targeting EGFR, KRAS, ALK, and BRAF V600E are case reports and there is no effective treatments. Immunotherapy has rewritten the treatment pattern of NSCLC. However, the current application of immunotherapy in PSC are mostly case reports. In immunotherapy, IMpower150 research data suggests that the combination of immunity and anti-angiogenesis + platinum-containing dual-agent chemotherapy can bring sustained OS benefits in NSCLC patients , and safety tolerated. However, PSC has moderate to high tumor mutation burden (TMB >10 mutations/Mb). This high mutation rate may increase tumor immunogenicity, making immunotherapy a better treatment option. At the same time, VEGF, as a cytokine that promotes the growth and differentiation of vascular endothelial cells, plays a decisive role in promoting tumor neovascularization. In this regard, immunotherapy combined with anti-angiogenesis and chemotherapy is worth exploring in the treatment of PSC.

• 5.Have received other PD-1 monoclonal antibody therapy or other immunotherapy against PD-1/PD-L1;
• 6.Active infection or fever of unknown origin occurred during the screening period and before the first administration>38.5℃ (according to the judgment of the investigator, the subject can be included in the group for fever caused by the tumor);
