Gastrinomas are functionally active pancreatic neuroendocrine tumors (NETs) secreting gastrin and are associated with local or regional metastases in 60% of the cases. Somatostatin analogs (SSAs) are currently recommended as a first-line treatment for the symptomatic treatment of NETs. Although antiproliferative activity of SSAs has been demonstrated in various cancer types in several in vivo and in vitro studies, clinical benefits with SSAs have been only achieved in a small proportion of patients. We report a disease control on a long-acting SSA lanreotide in a patient with metastatic gastrinoma...

Thyroid papillary microcarcinomas (PMCs) usually follow a very benign clinical course and are rarely metastatic. Any case of PMC presenting with distant metastases without any rising thyroglobulin level should be suspected to have any other primary apart from the thyroid and a meticulous clinical and diagnostic approach should be considered to identify the second primary. We hereby present a case of 52-year-old female treated as PMC with metastatic liver lesion, which was initially thought to be of thyroidal origin...

Gastric mixed adenoneuroendocrine carcinoma(MANEC)with multiple liver metastases is a rare condition with most data being derived from case reports. We present a case with liver metastases from gastric MANEC that respond remarkably to chemotherapy. Sixty-one-year-old male with severe anemia referred to surgical consultation due to advanced gastric cancer with multiple liver metastases. To relieve uncontrollable tumor bleeding, simple distal gastrectomy for symptom palliation was performed. Based on the tentative diagnosis with gastric poorly differentiated adenocarcinoma, a course of TS-1 and oxaliplatin therapy was administrated...

RATIONALE: Esophageal neuroendocrine tumors (NETs) are a rare type of esophageal tumor which are usually positive for chromogranin A, synaptophysin, and CD56 in tumor immunohistochemical staining. The most common symptoms of esophageal NETs are gastrointestinal symptoms such as dysphagia and/or abdominal discomfort. While esophageal NETs have the potential for distant metastasis, there have only been a few reports of brain metastasis originating from esophageal NET. PATIENT CONCERNS: We report the case of a 60-year-old Taiwanese female who initially presented with a 1 month history of painless forehead and bilateral neck masses...

RATIONALE: Rectal neuroendocrine tumor (NET) is a relatively rare tumor. Well-differentiated NETs (G1 and G2) rarely display distant metastasis at initial diagnosis. Currently, treatment for the primary lesions of rectal NETs with liver metastasis remains controversial. The liver metastasis was resected in local hospital. Transanal endoscopic microsurgery (TEM) has emerged as an effective minimally invasive surgery for local resection of lower rectal lesions. Herein, we reported the initial application of TEM to remove the rectal primary lesion in patients with low rectal NETs (G2) with giant liver metastases...

BACKGROUND: Liver metastases are common in patients with neuroendocrine tumors (NETs), having a negative impact on disease prognosis. The options for selective therapy in patients with unresectable multiple liver metastases are limited to TACE (transarterial chemoembolization), TAE (transarterial embolization), or SIRT (selective internal radiation therapy). AIM: To explore the clinical outcome, survival and safety of these therapies in NETs patients. METHODS: Retrospective case series of consecutive patients (mean age 56...

Liver metastases occur in nearly half of NET patients (MNETs) and heavily affect prognosis, with 5-yr. OS around 19-38%. Although it is difficult to show outcome differences for available treatments, due to the long course of disease, surgery for MNETs remains the most effective option in terms of survival and symptom control. Since MNETs frequently present as an oligo-metastatic, liver-limited disease, unresectable in 80% of cases, liver transplantation (LT) has emerged as a potential curative treatment. Nevertheless, experience with LT for MNETs is limited and burdened by highly heterogeneous outcomes and significant recurrence rate, mostly explained by the variability of selection criteria...

BACKGROUND: Twenty-seven percent of neuroendocrine tumors (NETs) are associated with distant metastases, and in some patients, the primary site is unknown. Orthopedia homeobox protein (OTP) has been described as a useful marker for lung carcinoids (LCs) and for separating low-grade typical carcinoids (TCs) from intermediate-grade atypical carcinoids (ACs) in resection specimens. This study evaluated OTP, thyroid transcription factor 1 (TTF-1), and Ki-67 expression in fine-needle aspiration (FNA) samples of various NETs...

OBJECTIVES: Peptide receptor radionuclide therapy (PRRT) with lutetium-177 (Lu)-DOTATATE is regarded as a safe treatment option with promising results for patients with neuroendocrine neoplasia (NEN). We aimed to study the absorbed organ and tumor doses, the renal and hematological toxicity as well as their mutual interaction. Another aim was the identification of adverse effects as possible predictors which may affect survival. METHODS: A total of 30 (14 female and 16 male) patients with inoperable/metastatic NEN were treated with 7...

BACKGROUND: Pancreatic panniculitis is a rare complication of pancreas disorders occurring in 0.3-3% of patients, most often accompanied by the pancreatic acinar carcinoma. It presents multiple, painful, deep, ill-defined, red-brown, migratory nodules and plaques of hard elastic consistency; often ulcerated and typically located on the lower proximal and distal extremities. The pathogenesis is not fully understood, but it is thought to result from lipolysis and fat necrosis with secondary tissue inflammation induced by pancreatic enzymes...

Ga-DOTATATE, a positron-emitting somatostatin analog, has been approved by the Food and Drug Administration for imaging neuroendocrine tumors (NETs). The presence of a second primary malignancy is common in NETs; however, synchronous primary malignancy in the thyroid has rarely been reported. The value of Ga-DOTATATE in medullary thyroid cancer is being investigated and is currently recommended for use when treatment with somatostatin analogs is an option. We present a 55-year-old man with abdominal pain associated with well-differentiated NET liver metastases and incidental medullary thyroid carcinoma demonstrated on a Ga-DOTATATE PET/CT...

Pancreatic cancer represents one of the most aggressive types of cancer, resulting in a late diagnosis and rapid death (poor overall survival). After adenocarcinoma (counting almost 80% of cases of pancreatic cancer), the second category, as frequency, is represented by the family of gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Pancreatic cancer is characterized by genetic heterogeneity and may results in different evolution among metastases, which may acquire driver mutations with the ability to transform under the action of several cancer treatments...
