This article is from Case Reports in Oncology, volume 7.AbstractPancreatic neuroendocrine tumors (NETs), including poorly differentiated carcinomas (NECs), are rarely encountered. The majority of these tumors do not secrete excess hormones, but functioning NETs produce large amounts of vasoactive peptides and may cause carcinoid syndrome. Synthetic somatostatin analogs (SSAs) have been widely used in NETs for control of hormonal syndromes. Here, we present a case of poorly differentiated, grade 3 pancreatic NEC associated with carcinoid syndrome, for which adequate symptom control was achieved for 2 years and 4 months using the long-acting SSA lanreotide Autogel®. In February 2009, a 55-year-old woman presented with episodes of flushing, diarrhea and epigastric pain. Imaging techniques revealed the presence of a metabolically active mass expressing somatostatin receptors in the hilar area of the liver. Histopathological examination confirmed the malignant nature of the mass, which was identified as a poorly differentiated grade 3 pancreatic NEC (TNM staging: T4NxM0). Therapeutic options were limited for the patient because of the extent of the primary mass involving the celiac axis, severe gastrointestinal toxicity experienced as a side effect of chemotherapy with cisplatin-etoposide and, later in the course of the disease, extensive liver metastases and carcinoid heart syndrome. Along with a palliative debulking surgery and right portal vein embolization, biotherapy with a high dose of lanreotide Autogel (120 mg-14 days) contributed to alleviation of symptoms caused by hormone overproduction, even after the development of liver metastases. These results suggest that patients with poorly differentiated NECs who exhibit signs of carcinoid syndrome can benefit from treatment with somatostatin analogs.
