    Therapeutic ROS and Immunity in Cancer-The TRIC-21 Meeting
    (Basel : MDPI, 2021) Bekeschus, Sander; Emmert, Steffen; Clemen, Ramona; Boeckmann, Lars
    The first Therapeutic ROS and Immunity in Cancer (TRIC) meeting was organized by the excellence research center ZIK plasmatis (with its previous Frontiers in Redox Biochemistry and Medicine (FiRBaM) and Young Professionals' Workshop in Plasma Medicine (YPWPM) workshop series in Northern Germany) and the excellence research program ONKOTHER-H (Rostock/Greifswald, Germany). The meeting showcased cutting-edge research and liberated discussions on the application of therapeutic ROS and immunology in cancer treatment, primarily focusing on gas plasma technology. The 2-day hybrid meeting took place in Greifswald and online from 15-16 July 2021, facilitating a wide range of participants totaling 66 scientists from 12 countries and 5 continents. The meeting aimed at bringing together researchers from a variety of disciplines, including chemists, biochemists, biologists, engineers, immunologists, physicists, and physicians for interdisciplinary discussions on using therapeutic ROS and medical gas plasma technology in cancer therapy with the four main sessions: "Plasma, Cancer, Immunity", "Plasma combination therapies", "Plasma risk assessment and patients studies", and "Plasma mechanisms and treated liquids in cancer". This conference report outlines the abstracts of attending scientists submitted to this meeting.

    Plasma, cancer, immunity
    (Bristol : IOP Publ., 2022) Bekeschus, Sander; Clemen, Ramona
    Albeit heavily investigated for several decades already, the importance of the immune system in targeting cancer has received wide clinical attention only in recent years. This is partly because of long-standing rather traditional concepts on tumor biology on the one hand and the complexity of the immune system and its processes on the other. The viewpoint of evaluating existing and emerging approaches in oncology based on toxicity to tumors and the ability to engage antitumor-immunity is gaining ground across several disciplines. Along those lines, cold physical plasma was suggested as potential anticancer tool more than a decade ago, but solid evidence of the immune system playing a role in plasma cancer treatment only emerged in recent years. Moreover, plasma may support cancer immunotherapies in the future. Cancer immunotherapies are systemic treatments with biologicals that were reported to synergize with existing local physical modalities before, such as radiotherapy and photodynamic therapy. This review outlines key concepts in oncology, immunology, and tumor therapy, links them to plasma research, and discusses immuno-oncological consequences. Finally, promising future clinical applications are summarized. Synoptically, first scientific evidence supports an immuno-oncological dimension of plasma cancer treatment in selected instances, but robust clinical evidence is still lacking. More basic and clinical research is needed to determine the immuno-molecular mechanisms and detailed plasma application modalities to facilitate real patient benefit in the long term.
