I'm considering a PubMedQA question regarding the use of serum for analyzing EGFR mutation status in advanced non-small cell lung cancer. Based on existing knowledge, serum can potentially detect EGFR mutations using circulating tumor DNA, despite some sensitivity limitations. It seems like the answer would be "yes," given that many studies support this. But I’ll also need to account for the possibility that the question could lean towards "maybe" if the reliability isn't clear.
