Interventions

BIOLOGICALTumor Treatment Vaccine; PD-1/L1 inhibitors

Before and after the patient's treatment period using PD-1 inhibitors，patients will receive tumor treatment vaccine(TTV), which would be given deep subcutaneously in the arm or near the tumor.The initial dose is 1ml each time, if the reaction isn't obvious, the dose can be appropriately increased to 2.5-4.0ml each time.The interval between injections can be shortened or extended depending on the patient's condition and response.
