ABSTRACT
BACKGROUND:
Daily experience tells us that breast cancer can be controlled using standard protocols up to the advent of a relapse. Now new frontiers in precision medicine like liquid biopsy of cell free DNA (cfDNA) give us the possibility to understand cancer evolution and pick up the key mutation on specific cancer driver gene. However, tight schedule of standardized protocol may impair the use of personalized experimental drugs in a timely therapeutic window. MAIN BODY Here, using a combination of deep next generation sequencing and cfDNA liquid biopsy, we demonstrated that it is possible to monitor cancer relapse over time. We showed for the first time the exact correspondence from the increasing clonal expansion and clinical worsening of metastatic breast cancer.CONCLUSION:
Thanks to liquid biopsy may be possible to introduce new experimental drugs in the correct therapeutic window which would lead in the near future to an effective treatment which otherwise remains challenging.
