Role of dual anti-HER2 therapy before liver resection for rectal metastases

This case presents a patient with a diagnosis of metastatic colon cancer on second-line chemotherapy. He demonstrated increased HER2 expression and was placed on dual HER2 antagonists. The patient had excellent repose and was ultimately able to undergo definitive liver resection for cure. We highlight the evolving use targeted therapy in metastatic colorectal cancer to not only extend progression-free survival, but act as a bridge to surgery.
