Outline of Final Research Achievements

The aim of this study was to investigate the clinicopathological factors of RET-rearranged lung carcinoma. We detected 22 (1.2%) of RET-rearranged lung carcinoma. All of them were adenocarcinoma histology and they tended to be younger age occurrence and no smoking history. To develop the diagnostic test for small sample, we evaluated the utility of digital mRNA count method. To evaluate the desirable combination therapy in RET-rearranged lung carcinoma, we analyzed the expression pattern for βIII-tubulin, ribonucleotide reductase subunit M1, thymidylate synthase, and programmed cell death 1 receptor expression. There were no differences inβIII-tubulin, ribonucleotide reductase subunit M1, and thymidylate synthase expression between RET-rearranged lung carcinoma and wild type adenocarcinoma. Whereas, PD-L1 low expression was observed in RET-rearranged lung carcinoma compared to wild type adenocarcinoma.
