MET and gastric cancer: In biodistribution studies of xenografts in mice models, the uptake of 89Zr-N-sucDf-DN30 (89Zr-DN30) in FaDu (human head-and-neck cancer with low c-MET expression) tumors was significantly lower than that in GTL-16 (human gastric cancer with high c-MET expression) tumors, specifically, at 3 days p.i. 7.8 ± 1.2%ID/g was detected in FaDu tumors and 18.1 ± 4.5%ID/g in GTL-16 tumors.
