Peritoneal carcinomatosis is a challenging condition that has limited treatment options. However, recent advances in immunotherapy, such as immune checkpoint inhibitors and CAR-T cells, show promise in improving outcomes for patients. Combining different immunotherapeutic approaches may further enhance treatment efficacy. Further research is needed, but immunotherapy holds potential as an effective and tolerable treatment for peritoneal carcinomatosis.
Simple Summary Peritoneal carcinomatosis is a challenging condition that affects many cancer patients, and conventional therapies have limited efficacy in treating it. However, recent advances in the field of immunotherapy have shown promise in improving treatment outcomes. One promising approach is immune checkpoint inhibitors, which block proteins that inhibit T-cell activity and promote an anti-tumor immune response. Another approach involves the use of CAR-T cells, which are genetically modified T cells engineered to recognize and target cancer cells expressing specific antigens. In addition, dendritic cells and vaccine-based therapeutics are also designed to stimulate the immune system to recognize and attack cancer cells. The authors also discuss the potential benefits of combining different immunotherapeutic approaches to improve treatment efficacy. While there is still much to be learned about the use of immunotherapy for peritoneal carcinomatosis, the available evidence suggests that it holds promise as a potentially effective and well-tolerated treatment option. Peritoneal metastasis, also known as peritoneal carcinomatosis (PC), is a refractory cancer that is typically resistant to conventional therapies. The typical treatment for PC is a combination of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Recently, research in this area has seen significant advances, particularly in immunotherapy as an alternative therapy for PC, which is very encouraging. Catumaxomab is a trifunctional antibody intraperitoneal (IP) immunotherapy authorized in Europe that can be used to diminish malignant ascites by targeting EpCAM. Intraperitoneal (IP) immunotherapy breaks immunological tolerance to treat peritoneal illness. Increasing T-cell responses and vaccination against tumor-associated antigens are two methods of treatment. CAR-T cells, vaccine-based therapeutics, dendritic cells (DCs) in combination with pro-inflammatory cytokines and NKs, adoptive cell transfer, and immune checkpoint inhibitors are promising treatments for PC. Carcinoembryonic antigen-expressing tumors are suppressed by IP administration of CAR-T cells. This reaction was strengthened by anti-PD-L1 or anti-Gr1. When paired with CD137 co-stimulatory signaling, CAR-T cells for folate receptor cancers made it easier for T-cell tumors to find their way to and stay alive in the body.
