Background: Cancer antigen CA72-4 is a tumor marker found to be elevated in a variety of human adenocarcinomas. Using the DRG TM-CA72-4, we quantified the elevation of CA72-4 compared to current United States Food And Drug Administration-approved tumor markers in various cancer types.
Materials And Methods: We conducted a prospective, single-center study enrolling 96 patients between March 2013 and August 2016 with different locally advanced, unresectable or metastatic cancer known to express CA72-4. Quantification of CA72-4 was performed according to the manufacturer's instructions using the DRG TM-CA72-4 enzyme-linked immunosorbent assay kit and the positivity rates were calculated.
Results: CA72-4 expression varied with tumoral site of origin, with the highest positivity rates found in pancreatic and ovarian malignancies. Correlation with clinical activity was also noted in some patients.
Conclusion: CA72-4 may have a potential role as an adjunct to conventional biomarkers in disease monitoring of pancreatic, ovarian and colorectal carcinomas.

Oligorecurrent prostate cancer (PCa) can be treated with metastasis-directed therapy (MDT), which may be performed using radioguided surgery (RGS) as an experimental approach. These procedures have shown promising outcomes, largely due to the high lesion detection rate of positron emission tomography/computed tomography (PET/CT). We present a case series of patients who underwent RGS following robot-assisted radical prostatectomy (RARP).

Although neo-antigen mRNA vaccines are promising for personalized cancer therapy, their effectiveness is often limited by the immunosuppressive tumor microenvironment (TME). The adenosine AA receptor (AAR) inhibits dendritic cell (DC) function and weakens antitumor T cell responses through hypoxia-driven mechanisms within the TME. This review explores a novel strategy combining neo-antigen mRNA vaccines with AAR antagonists (AARi).

ISB 1442 is a bispecific biparatopic antibody in clinical development to treat hematological malignancies. It consists of two adjacent anti-CD38 arms targeting non-overlapping epitopes that preferentially drive binding to tumor cells and a low-affinity anti-CD47 arm to enable avidity-induced blocking of proximal CD47 receptors. We previously reported the pharmacology of ISB 1442, designed to reestablish synthetic immunity in CD38+ hematological malignancies.

CAR-T cell therapy has revolutionized immunotherapy but its allogeneic application, using various strategies, faces significant challenges including graft-versus-host disease and graft rejection. Recent advances using Virus Specific T cells to generate CAR-VST have demonstrated potential for enhanced persistence and antitumor efficacy, positioning CAR-VSTs as a promising alternative to conventional CAR-T cells in an allogeneic setting. This review provides a comprehensive overview of CAR-VST development, emphasizing strategies to mitigate immunogenicity, such as using a specialized TCR, and approaches to improve therapeutic persistence against host immune responses.
