EGFR and malignant colon neoplasm: Of note, a significantly higher cytotoxicity was induced by UCB-NK in EGFR−RASwt (42 ± 8 versus 67 ± 7%), EGFR+ RASmut (20 ± 2 versus 37 ± 6%), and EGFR+ BRAFmut (23 ± 3 versus 43 ± 7%) colon cancer cells compared to A-PBNK and equaled the cytotoxic efficacy of the combination of A-PBNK and cetuximab.
