Paper:A Tobacco smoking and somatic mutations in human bronchial epithelium (Nature. 2020;578;266-272.)

First of all, I would like to express heartfelt condolences for Mr. Paul Bourdarie. I am grateful to the Foundation and the co-authors, who were involved in this study, for receiving this award. The profound effects of tobacco on the genome of lung cancer cells are well-documented, but equivalent data for normal bronchial cells are lacking. In this study, we aimed to study genetic alterations in normal bronchial epithelial cells in detail. As a result, we showed that tobacco smoking significantly increased somatic mutations in normal bronchial epithelial cells. Driver mutations, which are thought to be direct causes of lung cancer development, also increased with smoking. A population of cells in individuals with a history of smoking had mutational burdens that were equivalent to those expected for people who had never smoked. These “near-normal” cells were more frequent in ex-smokers than current smokers, which could be associated with the reduction of lung cancer incidence after stopping smoking. Thus, this study highlighted the harmful effect of tobacco smoking and the importance of quitting smoking, which is expected to be messages contributing to the elimination of lung cancer in the future. Based on the result of this study, I hope to continue the research for the early detection or prediction of lung cancer in the future.

Paper:Combination of host immune metabolic biomarkers for the PD-1 blockade cancer immunotherapy. (JCI Insight. 2020 Jan 30; 5(2): e133501.Published online 2020 Jan 30.)

I would like to express my heartfelt gratitude for receiving the 9th Kiyoko and Paul Bourdarie-Goto Scientific Prize (Special Award). For about 20 years, I have been involved in cancer immunology research, which uses immune power to treat cancer. Until about 10 years ago, cancer immunotherapy was regarded as something to be frowned upon and its importance was not paid attention to. However, with the discovery of PD-1blockade antibody therapy, cancer immunotherapy has now become a front-line treatment in the field of lung cancer. It is necessary to identify biomarkers that can distinguish between patients who respond and those who do not. Since many factors on both the cancer and immune sides are involved in the cancer immune response, it was necessary to combine multiple biomarkers rather than a single marker. I’m very honored to have been recognized for this research paper. In the future, we would like to clarify the biological significance of these markers and further develop them for the use in actual clinical practice.
