ABSTRACT
Patients with non-small cell lung cancer (NSCLC) are treated in a variety of ways. In addition to radiotherapy, chemotherapy and targeted therapy, breakthroughs have been made in immune checkpoint inhibitors, in particular, programmed cell death 1 (PD-1) and its ligand (PD-L1) inhibitors have achieved survival benefits for NSCLC patients, and some of them have been approved as first-line drugs by the US Food and Drug Administration. Currently, commonly used PD-L1 inhibitors are atezolizumab, durvalumab and avelumab. Combination therapies include combination with chemotherapy, anti-vascular endothelial growth factor drugs, molecular targeted therapy and immunotherapy.
ABSTRACT
S-1 and capecitabine are relatively ideal agents for maintenance treatment of advanced gas-tric cancer. In clinical trials of using immune and targeted drugs for maintenance treatment of advanced gastric cancer,ipilimumab fails to obtain positive results,ramucirumab has not obtained research data,and trial regimens of maintenance treatment with trastuzumab,bevacizumab and avelumab have all shown initial efficacy. Traditional Chinese medicine therapy has shown some effectiveness in maintenance treatment,which still needs further researches.
