Colorectal cancer (CRC) is the second leading cause of cancer deaths in western countries. The five-year survival rate in early-stage CRC patients falls from 90% to 60% with lymph node involvement and to 10% with metastases. Early detection and treatment of mCRC would benefit from an easily obtainable biomarker signature (bio-signature) to characterize patient subpopulations. The core hypothesis for this project is that a liquid biopsy can serve as a source of rare circulating cells (CTCs) to represent or complement the traditional solid biopsy. The project is an observational clinical study in two stages, with a possible third stage, to sample CTCs and solid tissue site image from patients with metastatic colorectal cancer (mCRC) undergoing liver resection. Cell-free DNA will also be collected as part of the liquid biopsies for later analysis if warranted.
- Determine the level of correlation between liquid (blood) and solid (tumor touch prep) biopsies.
- Develop biosignatures for liquid biopsy representation of solid biopsies through genomic, proteomic, and morphometric profiling of primary tumor, circulating cells, and metastases.
- Correlate multivariate profiling to outcome; predict recurrence.
