Acupuncture Combined With PD-1/PD-L1 Inhibitors for Advanced Lung Cancer

This study will be a preliminary evaluation of the efficacy and safety of acupuncture to enhance the response rate of immunotherapy in advanced lung cancer.The main questions it aims to answer are:1.Does acupuncture higher the response rate of immunotherapy in advanced lung cancer? 2.Does acupuncture higher the safety of immunotherapy in advanced lung cancer? Researchers will compare acupuncture to a sham acupuncture to see if acupuncture could enhance the response rate of immunotherapy in advanced lung cancer.Both groups will receive standard anti-tumor western medical treatment regimen (PD-1/PD-L1 inhibitor combined with chemotherapy), and the experimental and control groups will be treated with 4 cycles of acupuncture or sham-acupuncture on top of the anti-tumor treatment regimen, respectively. Patients were followed up every three weeks for the first three months and every three months thereafter to record any disease progression, adverse events, survival or mortality status and so on.
