In particular, colorectal malignancies predominantly express sst1 (65%) followed by sst5 (39%) and sst2 (36%) [197], hepatocellular carcinomas express mainly sst5, although sst1, 2, and 3 are also often detected (about 40–60%) [198], while in gastric carcinomas sst2 and 5 are very commonly expressed, although sst3 is detected in several cases [199]. This evidence concerns the gene CORT and gastric carcinoma.
