Core Tip

Core tip: The prognosis for patients with recurrent or metastatic colorectal cancer (CRC) is extremely poor. Immunotherapy may be effective for treating CRC patients and/or preventing relapse. The immunotherapeutic approaches for CRC, including peptide vaccines, dendritic cell-based cancer vaccines, whole tumor cell vaccines, viral vector-based cancer vaccines, adoptive cell transfer therapy, antibody-based cancer immunotherapy, and cytokine therapy have been demonstrated. The blockade of multiple immune regulatory checkpoints combined with immunotherapy and/or conventional chemotherapy may be effective in treating patients with advanced CRC.
