Small-scale clinical studies on its use for adenocarcinoma of other origin [21,22] and preclinical studies on the use of lanreotide in pancreatic ductal adenocarcinoma [23] showed no effect on tumor size and growth even after in vitro SSTR2 gene transfer, although SSTR2 gene transfer itself led to inhibition of tumor growth. Here, SSTR2 is linked to pancreatic ductal adenocarcinoma.
