Udhayvir Grewal: Do you consider anti-EGFR moAbs in HER2+, RAS wild-type colorectal cancer?

Udhayvir Grewal, Resident Physician at Ochsner LSU Health Shreveport Academy medical centre, shared a post on X:

“Do you consider anti-EGFR moAbs (Cetuximab or Panitumumab) in HER2+, RAS wild-type colorectal cancer? Some preclinical data suggest that there is some degree of primary resistance to anti-EGFR therapy in HER2+ CRC (mediated by downstream activation of ERK/2 pathway).
This was also demonstrated by a large retrospective analysis (lower ORR, higher risk of progression, similar OS).”
