| Outline of Final Research Achievements |
Genome-wide analysis for pilot samples from 10 patients with colorectal liver metastases (CLM) revealed that polymorphism in transmembrane region of MICA gene could be a new biomarker for response to chemotherapy and postoperative prognosis. Validation analysis using samples from 58 patients confirmed very high concordance rate in MICA genotype between tumor tissue and normal liver parenchyma (96.4%) and that MICA A5.1 is associated with pathologic response to chemotherapy and better survival outcomes. These results suggest that MICA genotype can be a potential biomarker for patients undergoing chemotherapy and surgery for CLM.
