The 31st Annual Meeting of Japanese Association of Cancer Immunology【Nagasaki Prefecture】
The 31st Annual Meeting of Japanese Association of Cancer Immunology (JACI2027) will take place July 29–31, 2027, at Dejima Messe Nagasaki in Nagasaki, Japan. Under the theme “Standing on the shoulders of giants,” this scientific meeting aims to connect fundamental and clinical cancer immunology research and advance the development of evidence-based cancer immunotherapies. A special lecture by Dr. Robert D. Schreiber, known for proposing the cancer immunoediting hypothesis, and scientific exchanges among domestic and international researchers are planned.
Meeting Theme and Objectives
Standing on the shoulders of giants
Decades of fundamental research have enabled cancer immunotherapies to become clinical treatment options. However, only a proportion of patients currently benefit from these treatments, highlighting the need for further research and development. The meeting seeks to build upon the scientific achievements of earlier generations and advance cancer immunology research.
The Japanese Association of Cancer Immunology traces its origins to a cancer immunology research group established in 1996 and has operated as a general incorporated association since 2024. It promotes collaboration among basic scientists, clinical researchers, physicians and industry, supporting the scientific development of cancer immunotherapies and internationally recognized research.

Key Research Areas and Highlights
The following research areas are relevant to JACI’s activities and the research conducted at the Department of Medical Oncology, Nagasaki University, where the meeting president is based. They are not a confirmed list of individual sessions.
- Cancer Immunoediting: Immune-mediated tumor elimination and selection, and mechanisms through which cancer cells evade immune responses.
- Tumor Microenvironment (TME): Interactions between tumor and immune cells, tumor-infiltrating lymphocytes (TILs), and analysis of immunosuppressive environments.
- Immune Checkpoints: Regulation of antitumor immunity, immune checkpoint inhibitors and research into treatment responses.
- Cell and Gene Therapies: CAR-T cell therapy, TCR-engineered T cell therapy and adoptive cell therapy.
- Personalized Cancer Immunotherapy: Neoantigen-targeted therapies and analysis of patient-specific immune responses.
- Translational Research: Translating fundamental discoveries into clinical applications and developing treatments that address therapeutic resistance and tumor heterogeneity.
Pharma Nexus highlights: Spatial proteomics, multiplex immunofluorescence, tissue imaging, flow cytometry, cell culture and immune cell functional assays are highly relevant to understanding the tumor microenvironment and developing cancer immunotherapies. These are related research technologies, not confirmed individual presentations or exhibited products at this meeting.
