Brief summary

Currently, chemotherapy, targeted therapy, immunotherapy, and radiotherapy are the core treatment modalities for malignant tumors, with technologies advancing rapidly. Radiotherapy can induce massive tumor cell death in a short period and expose abundant tumor-specific antigens, turning the irradiated tumor into an endogenous tumor vaccine and even causing regression or disappearance of non-irradiated tumors (the abscopal effect) . Preclinical studies have shown that stereotactic body radiotherapy (SBRT) combined with PD-1/PD-L1 inhibitors can activate systemic immunity, sensitize tumor-specific T cells to enter the bloodstream, and enable their homing to distant tumors, thereby inhibiting the growth of non-irradiated tumors . However, conclusions from rigorous randomized controlled trials have limitations when applied to the complex and heterogeneous patient populations in real-world settings. Real-world research is increasingly valued globally to complement traditional clinical trial evidence. This project prospectively collects data from patients receiving immunotherapy combined with radiotherapy in real-world clinical practice, which is of great value for evaluating long-term efficacy, safety, and impact on quality of life, and can provide high-level evidence for optimizing clinical practice and informing healthcare decisions.
