When the amount of 111In-octreotide biodistribution was normalized to the CT-determined tumor weight (% ID/g) without necrosis, Ad-CMV-HA-SSTR2 gene expression remained significantly greater than Ad-CMV-GFP control (p<0.02 for IA, n = 6 and p = 0.01 for IT, n = 4; Fig. 4D). This evidence concerns the gene SSTR2 and neoplasm.
