Task: Answer Verification
Input (English): Question: Does next-Generation Sequencing of Matched Primary and Metastatic Rectal Adenocarcinomas demonstrate Minimal Mutation Gain and Concordance to Colonic Adenocarcinomas?
Answer: -The somatic mutations identified in our rectal adenocarcinoma cohort showed a strong correlation to those previously characterized in colonic adenocarcinoma. In addition, most rectal adenocarcinomas harbored identical somatic mutations in both the primary tumor and metastasis. These findings demonstrate evidence that rectal adenocarcinoma follows a similar molecular pathogenesis as colonic adenocarcinoma and that sampling either the primary or metastatic lesion is valid for initial evaluation of somatic mutations and selection of possible targeted therapy.
Output (English): yes
