HER2 SHOULD BE USED TO INFORM TREATMENT DECISIONS IN COLORECTAL CANCER1

NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) recommend testing for HER2 amplification in patients with unresectable or metastatic colorectal cancer2,3

HER2 amplification may be associated with a lower response rate and shorter PFS in patients treated with anti-EGFR therapies.4,5

  • Currently, anti-EGFR agents are a common treatment approach for RAS/BRAF WT mCRC in later lines of therapy1,5
  • However, HER2 amplification may be associated with decreased activity of anti-EGFR therapies in patients with RAS/BRAF WT mCRC4,5

NCCN Guidelines® recommend HER2-targeted therapies as subsequent treatment options in mCRC patients with tumors that have HER2 overexpression.2,3

Learn more about the importance of testing in mCRC.

Testing can help inform your treatment decisions.

List of Labs Testing for HER2 in mCRC

EGFR = epidermal growth factor receptor; HER = human epidermal growth factor receptor; mCRC = metastatic colorectal cancer; NCCN = National Comprehensive Cancer Network® (NCCN®); PFS = progression-free survival; WT = wild type.
