Un Unusual Tumor Association in Acromegaly Abstract #1913

Introduction: Acromegaly is associated with an increased risk for malignancies. Only a case of pseudomyxoma peritonei with ovarian and appendicular sequential tumors in acromegaly was described
Aim(s): We report the case of appendicular adenocarcinoma in acromegaly in progression despite controlled disease
Materials and methods: A 59 years old woman underwent partial neurosurgery in 2006 for invasive GHoma. Pt started treatment with somatostatin analogues and she underwent second neurosurgery in 2008. In 2010 for resistant disease pt was enrolled in PAOLA study with normalization of GH secretion. In January 2015 a left ovarian cyst was found and pt was followed-up with gynecological ultrasound. In September 2016 for increase in size and appearance of a contralateral lesion pt was oophorectomized-hysterectomized. Histological examination showed infiltration of mucinous adenocarcinoma of probably gastrointestinal origin with a neuroendocrine cell line differentiation. Colonoscopy and gastroscopy were negative. Ecoendoscopy-guided biopsy of gastric wall revealed metastasis of mucinous adenocarcinoma

#19 Antitumor activity of Pasireotide (SOM230) alone and in combination with Everolimus (RAD001) in DU-145 human prostate cancer model
Introduction: Pasireotide (SOM230) is a novel multi-receptor ligand somatostatin analogue with high affinity for somatostatin receptor subtypes sst1,2,3 and sst5. Like octreotide, which binds primarily to sst2, it inhibits hypersecretion of hormones from patients with functional pituitary tumors and gastroenteropancreatic neuroendocrine (GEP/NET) tumors. In addition, tumor shrinkage has been observed with both compounds in patients with acromegaly, Cushing’s disease and GEP/NETs, but its tumor-reducing mechanism of action has so far not been revealed. In patients with breast and liver cancer, octreotide had little or no antitumor activity.
