Outline of Final Research Achievements

The gene analysis of occupational cholangiocarcinoma revealed a high mutation burden and a unique trinucleotide mutation signature and multicentric carcinogenesis. By immunohistochemical analysis, cholangiocarcinoma cells and massive invasion of immune cells including cytotoxic T cells were positive for PD-1 and PD-L1. The combined positive score was 10% to 90%, which was extremely higher than non-occupational cholangiocarcinoma. These findings indicate that occupational cholangiocarcinoma has characteristic immune response such as a high mutation burden, cancer immune cells positive for PD-1 and PD-L1, massive invasion of immune cells, which suggests the usefulness of immune checkpoint inhibitors.

Academic Significance and Societal Importance of the Research Achievements

本研究は職業性胆管癌と通常の胆管癌における遺伝子解析および病理学的検討を行った結果、通常の胆管癌に比較し、職業性胆管癌では著明な遺伝子変異、著明なPD-1やPD-L1陽性を示す癌細胞や浸潤免疫細胞、著明な細胞障害性T細胞を含む免疫細胞浸潤など特徴的な免疫応答が惹起されていた。このことは、胆管癌発癌において特異な免疫応答が惹起され、その特徴を活用した治療法が存在することが判明した。すなわち本研究によって胆管癌の発癌メカニズムやそれに伴う病態の解明と、新たな治療法の開発に結び付けることができた。
