Combined Analysis of Concordance between Liquid and Tumor Tissue Biopsies for <i>RAS</i> Mutations in Colorectal Cancer with a Single Metastasis Site: The METABEAM Study

Abstract

Plasma ctDNA-based liquid biopsy in patients with mCRC may be useful depending on the metastatic site. The maximum diameter and lesion number should be carefully considered when determining patients' <i>RAS</i> status with only peritoneal or lung metastases.
