Purpose: Colorectal cancer (CRC) remains one of the leading causes of cancer-related mortality worldwide. Metastatic colorectal cancer (mCRC) continues to present significant challenges, particularly in patients with proficient mismatch repair/microsatellite stable (pMMR/MSS) tumors. This narrative review aims to provide recent developments in immunotherapy for CRC treatment, focusing on its efficacy and challenges.

Tumor-specific cytotoxic T cell immunity is critically dependent on effective antigen presentation and sustained signal transduction. However, this immune response is frequently compromised by the inherently low immunogenicity of breast cancer and the deficiency in major histocompatibility complex class I (MHC-I) expression. Herein, a chimeric peptide-engineered stoichiometric polyprodrug (PDPP) is fabricated to potentiate the cytotoxic T cell response, characterized by a high drug loading capacity and precise stoichiometric drug ratio, of which the immunogenic cell death (ICD) inducer of protoporphyrin IX (PpIX) and the epigenetic drug of decitabine (DAC) are condensed into a polyprodrug called PpIX-DAC.

The recent advancements in cancer immunotherapy have spotlighted the potential of natural killer (NK) cells, particularly chimeric antigen receptor (CAR)-transduced NK cells. These cells, pivotal in innate immunity, offer a rapid and potent response against cancer cells and pathogens without the need for prior sensitization or recognition of peptide antigens. Although NK cell genetic modification is evolving, the viral transduction method continues to be inefficient and fraught with risks, often resulting in cytotoxic outcomes and the possibility of insertional mutagenesis.

Background Aims: With novel therapies improving prognosis, the complications of multiple myeloma after multi-line treatment, particularly myelosuppression, have become a crucial determinant of long-term outcomes. Non-myeloablative allogeneic hematopoietic stem cell transplantation is a feasible option, but the transplant-related mortality rate remains high. Our study presents a relapsed/refractory multiple myeloma patient with a 9-year disease history.

Background: B-cell maturation antigen (BCMA)-targeted T cell-redirecting immunotherapies, including Chimeric Antigen Receptor (CAR) T-cell therapy and T-cell engagers have demonstrated remarkable success in treating relapsed/refractory (RR) multiple myeloma (MM), a malignancy of plasma cells. However, a significant challenge is the severe side effects associated with T-cell overactivation, leading to cytokine release syndrome and neurotoxicity in MM patients undergoing such therapies. Bispecific NK cell engagers (NKCEs) may offer a promising alternative by redirecting NK cell cytotoxic activity towards tumor cells without triggering cytokine release syndrome.
