Outline of Final Research Achievements

Ultrasensitive EGFR gene mutation measuring system was constructed using tissue samples and blood samples in non-small cell lung cancer patients.This result is significant in realizing quantification of EGFR gene mutation with non-invasive methoed. With development future genome medicine, we considered important in evaluating choice of treatment policy and efficacy of treatment based on the evaluation of allele frequency in EGFR gene mutation and other somatic gene mutataion.

Academic Significance and Societal Importance of the Research Achievements

侵襲性の低い血液検体での遺伝子検査方法の確立が、今後のがんゲノム医療の発展に寄与し得ると考える。
