Pasireotide-treated Men1+/− mice had increased survival (pasireotide, 80.9% vs PBS, 65.2%; P < .05), with fewer mice developing pancreatic NETs (pasireotide, 86.9% vs PBS, 96.9%; P < .05) and smaller increases in pituitary NET volumes (pre-treated vs post-treated, 0.803 ± 0.058 mm3 vs 2.872 ± 0.728 mm3 [pasireotide] compared with 0.844 ± 0.066 mm3 vs 8.847 ±1.948 mm3 [PBS]; P < .01). This evidence concerns the gene MEN1 and pancreatitis.
