    Background: The use of biomarkers to target anti-EGFR treatments for metastatic colorectal cancer (CRC) Erlotinib well-established, requiring molecular analysis of primary or metastatic biopsies. We aim to review concordance between primary CRC and its metastatic sites.
    Methods: A systematic review and meta-analysis of all published studies (1991–2018) reporting on biomarker concordance between primary CRC and its metastatic site(s) was undertaken according to PRISMA guidelines using several medical databases. Studies without matched samples or using peripheral blood for biomarker anal-ysis were excluded.

    1. Introduction
    Advances in biological therapies such as anti-epidermal growth factor receptor (EGFR) antibodies (cetuximab and panitumumab) have resulted in biomarkers being used to target metastatic CRC (mCRC) [11]. KRAS is a key proto-oncogene downstream of EGFR and is activated in up to 50% of sporadic mCRC patients, with 95% of activa-tions occurring in codons 12/13 of exon 2 [12]. Importantly, KRAS exon

    2–4 mutations (involving codons 12, 13, 161, 117 & 146) demonstrate a significantly lower response to cetuximab and panitumumab [13,14]. Some studies have also indicated that KRAS mutations may confer resis-tance to bevacizumab [15,16]. The extended RAS family of oncogenes includes NRAS, with exon 2–4 mutations occurring in 3–5% of CRC's and similarly resulting in a lower response [17,18]. BRAF, a RAF gene kinase and immediate downstream effector of KRAS, shows mutations in nearly 10% of colorectal adenocarcinomas and is also a strong nega-tive prognostic marker, predicting resistance to both cytotoxic and anti-EGFR therapy [19–21].
    Mutations in genes other than those constituting the RAS/RAF path-way include PIK3CA and PTEN [22]. Approximately 15–20% of patients with mCRC, have mutations in exon 20 of PIK3CA and demonstrate resistance to cetuximab even in the presence of KRAS wild type [23]. Loss of expression of PTEN, a natural inhibitor of PI3K-initiated signal-ling, has itself also been associated with unresponsiveness to cetuximab and reduced OS [24,25]. Beyond the factors associated with EGFR signal-ling pathways, a number of other genes are significantly mutated in CRC, including APC (51–81%), TP53 (20–60%), and SMAD4 (10–20%) [12]. APC is the most prevalent gene in the establishment of sporadic co-lorectal malignancy [26]. Similar to APC, the TP53 gene is heavily
