| Research Abstract |
This study was conducted to clarify the association between drug-metabolizing enzyme CYP2C19 gene mutation and liver cancer susceptibility. 21 liver and blood samples were donated from Japanese liver cancer patients who received partial hepatectomy. The results indicated that the gene mutation found in high frequency in metastatic liver cancer patients occur congenitally rather than arise in peripheral tumor site acquired by cancer condition.CYP2C19 activity decreased in all samples and the degree was associated with changes in several cytokines, but did not correlate with the genotype of the enzyme. For the prevention of metastasis and for the proper treatment of liver cancer, further studies elucidating the mechanisms and significance of the results obtained and clarifying the role of CYP2C19 in cancer patients are needed.
