• Expected survival >/= 6 months.
• Eastern Cooperative Oncology Group (ECOG) performance status score of 0 \~ 1；
• Sufficient tumor tissue samples can be obtained from subjects for genetic analysis, with at least 2 puncture tissues with a tumor purity of ≥ 50% required for puncture samples and at least 0.5cm of tissue required for surgical samples. Alternatively, the original gene sequencing data required for tumor neoantigen analysis can be provided, including full exon sequencing data of tumor tissue, transcriptome sequencing data, and full exon sequencing data of peripheral blood；
• Echocardiographic evaluation: left ventricular ejection fraction (LVEF) >/= 50%.

• For women of childbearing potential: having a negative serum or urine pregnancy test within 7 days prior to study initiation, agreement to remain abstinent or use contraceptive measures during the treatment period.
• For men: agreement to remain abstinent or use contraceptive measures during the treatment period.
• Able to comply with the study protocol and follow-up procedures.
• Voluntarily participate in the study and sign the informed consent form. If a subject is unable to read the informed consent form (e.g., illiterate subjects), a witness shall be present to observe the informed consent process and sign the informed consent form on their behalf.
