| Outline of Final Research Achievements |
It is one of the urgent issue to establish an appropriate companion diagnostic system to proceed precision medicine in oncology, especially lung cancer in which many targetable genomic and immunological alteration have been explored. The aim of this study is to explore the mechanism of discordancy and inappropriate results in pathological companion diagnostics of lung cancer, especially focusing on its intratumoral heterogeneity. Our results indicated that the morphological heterogeneity was the sum of genomic and epigenomic alterations, and the fundamental driver oncogenic mutation (such as ALK) was retained through progression, then modified by the additional alterations. Of lung cancer with MET exon 14 skipping mutation, morphology and/or IHC based system had low power for screening. Our study suggested the importance of quality control of PD-L1 IHC as a biomarker of ICI therapy and needs for further technical innovation to reproducibility.
