ERBB2 and hepatocellular carcinoma: Prior to this, Shultz et al. (2016) identified HER2 as a potential predictive biomarker for GEM-E, Kinzler et al. (2023) identified CXCL6 as a potential predictive biomarker for hepatocellular carcinoma patients undergoing trans arterial chemoembolization, and Fei et al. (2013) identified BMP2 as a predictive biomarker for patients with advanced non-small cell lung cancer undergoing chemotherapy.
