In this study, the investigators provide an individualized tumor neoantigen peptide vaccine in combination with radiotherapy to patients with advanced malignant solid tumors. The investigators observe the post-treatment tumor burden status, the immune response induced by immune preparations, and the prolongation of patient survival time, aiming to evaluate the effectiveness and safety of the individualized tumor neoantigen peptide vaccine in combination with radiotherapy
