Brief Summary: In this study, the investigators provide a combined treatment of personalized tumor neoantigen-based peptide vaccine and conventional third-line therapy to patients with colorectal cancer (CRC) progressed after second-line treatment. The investigators observe the objective response rate (ORR), disease control rate (DCR), adverse event (AE), serious adverse event (SAE), progression-free survival (PFS), and overall survival (OS) , aiming to evaluate the effectiveness and safety of the treatment.
Detailed Description: This study is conducted in accordance with the Declaration of Helsinki and the guidelines of the Consolidated Standards of Reporting Trials.

10 patients with CRC progressed after second-line therapy will be recruited in this study. With doctor's assessment, a combined treatment of conventional third-line therapy and personalized tumor neoantigen-based peptide vaccine treatment plan will be designed for each participant.

Here are the steps for preparing the neoantigen-based peptide vaccine:

Collecting venous blood samples; Blood PBMC exome sequencing; RNA transcriptome sequencing; Classifying HLA alleles; Performing bioinformatics analysis, finding meaningful mutations and about 20 neoantigen sequences for each patient; Synthesizing peptide neoantigens; Preparation of the personalized tumor neoantigen-based peptide vaccine.

Participants will receive a conventional third-line therapy course and 10 subcutaneous injections of the vaccine within a treatment period of 21 weeks. After treatment, participants will be followed in every 6 weeks till the end of the study. Venous blood collection, physical examination, ECOG Performance Status Scale assessment, CT/MRI scan, X-ray examination, laboratory examination, and other necessary examinations are required at each follow-up visit.
