BACKGROUND: Primary neuroendocrine tumors (NETs) in the presacral region are extremely rare, some of which are caused by other primary tumors or metastatic rectal carcinoids. Nevertheless, cases of NETs have been increasing in recent years. This report describes the first primary neuroendocrine tumor in the presacral region that was found at our hospital within the last five years. CASE SUMMARY: The patient was identified as a 36-year-old woman with a presacral mass and pelvic floor pain...

AIM: One of the primary prerequisites for peptide receptor radionuclide therapy (PRRT) in patients with neuroendocrine tumors (NET) is the presence of somatostatin receptors (SSTR) on NET cells. NET are highly heterogeneous and an individual patient as well as separate metastases can harbor cells with different clones, which influence the SSTR expression on NET cells. With this background we looked into our institutional database to assess the prognostic significance of quality of SSTR expression on SSTR PET/CT imaging in patients treated with at least two cycles of Lu-177 DOTATOC or Lu-177 DOTATATE...

BACKGROUND Tumor-to-tumor metastasis is an uncommon phenomenon in which a primary tumor metastasizes into another tumor. CASE REPORT An 81-year-old Asian woman was referred to our hospital for evaluation and treatment of a solid mass in the right middle lung lobe that had rapidly enlarged for 1.5 years compared to that observed over the last 5 years. On computed tomography (CT), the mass was 68×60 mm, and 2 different tumors appeared to exist in the upper portion of the mass. Blood examination findings revealed high serum levels of progastrin-releasing peptide and neuron-specific enolase...

BACKGROUND: Tumor-to-tumor metastasis (TTM) is a rare but well-documented phenomenon that is defined as metastasis in a histologically distinct tumor. Ovarian mature teratomas (OMTs) can coexist with various cancers by malignant transformation, which may make it difficult to distinguish these from TTM. Herein, we report a case of TTM from appendiceal adenocarcinoma to the OMT, mimicking the malignant transformation of OMT. CASE PRESENTATION: A 67-year-old Japanese woman underwent abdominal total hysterectomy and bilateral salpingo-oophorectomy for an ovarian tumor in another hospital...

A 42-year-old female developed type 1 diabetes mellitus at the age of 16 years and received insulin therapy. Esophagogastroduodenoscopy revealed an atrophic change localized in the gastric body and a small, protruding gastric lesion. Biopsy revealed that this lesion was gastric neuroendocrine tumor. Hence, the patient underwent en bloc resection by endoscopic submucosal resection with a ligation device. As the patient presented both autoimmune gastritis and type 1 diabetes mellitus, she was diagnosed with type 4 autoimmune polyendocrine syndrome...

Carcinoid tumors are rare neuroendocrine tumors (NETs) found mostly in the gastrointestinal system. The occurrence of NETs in the large intestine according to the location of origin distribute as follows; 54% in the rectum, 20% in the cecum, 7.5% in the sigmoid colon, 5.5% in the rectosigmoid colon and 5% in the ascending colon [1]. A complete cure is usually possible in cases diagnosed and treated early. Extensive lymph node dissection is crucial for colon cancer surgery [2]. To this end, various techniques have been proposed to achieve better oncological results...

BACKGROUND: Low-grade appendiceal mucinous neoplasms (LAMNs) are tumors that often present with widespread mucin in the peritoneal cavity (pseudomyxoma peritonei [PMP]). Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are effective treatment, but no published recommendations exist regarding surveillance. METHODS: Data from prospective databases of patients who underwent CRS-HIPEC from 2001 to 2017 at two high-volume institutions were retrospectively analyzed...

BACKGROUND: Histologic subtypes of appendiceal cancer vary in their propensity for metastases to regional lymph nodes (LN). A predictive model would help direct subsequent surgical therapy. METHODS: The National Cancer Database was queried for patients with appendiceal cancer undergoing surgery between 1998 and 2012. Multivariable logistic regression was used to develop a predictive model of LN metastases which was internally validated using Brier score and Area under the Curve (AUC)...

Summary: Ectopic ACTH-secreting pulmonary neuroendocrine tumors are rare and account for less than 5% of endogenous Cushing’s syndrome cases. We describe an unusual case of metastatic bronchial carcinoid tumor in a young woman presenting with unprovoked pulmonary emboli, which initially prevented the detection of the primary tumor on imaging. The source of ectopic ACTH was ultimately localized by a Gallium-DOTATATE scan, which demonstrated increased tracer uptake in a right middle lobe lung nodule and multiple liver nodules...

Ga-DOTATATE imaging is commonly used for the detection of metastatic disease in neuroendocrine tumors. We present a case of a 69-year-old woman postsurgery for lung carcinoid tumor in which sequential follow-up Ga-DOTATATE PET/CT studies identified focal hepatic uptake that was presumed to represent a liver metastasis. However, correlative imaging with MRI revealed a focal fatty sparing of the liver composed of benign hepatic parenchyma at that area accompanied with diffuse liver steatosis in the background of the "pseudolesion...

The treatment landscape of well-differentiated neuroendocrine tumors (NETs) has considerably expanded in recent years, and both somatostatin analogs, radiolabeled somatostatin analogs, everolimus, and sunitinib have been incorporated within the therapeutic armamentarium against these malignancies. Even in the context of multiple treatment options available, cytotoxic chemotherapy plays a pivotal role in the management of pancreatic NETs (panNETs), while its activity in midgut carcinoids and lung NETs is still debated...

INTRODUCTION: Insulinoma-associated protein 1 (INSM1) is an immunohistochemical marker for neuroendocrine differentiation with potentially superior sensitivity and specificity. INSM1 performance in pulmonary cytology cell block material (CB) has not been well established, and large series demonstrating its performance have been few. MATERIALS AND METHODS: Typical and atypical carcinoid, small cell lung carcinoma, and large cell neuroendocrine carcinoma, squamous cell carcinoma, and adenocarcinoma CBs and 563 surgical specimens comprising 17 typical carcinoid, 14 atypical carcinoid, 8 small cell lung carcinoma, 10 large cell neuroendocrine carcinoma, 58 squamous cell carcinoma, 415 adenocarcinoma, and 17 large cell carcinoma cases and 24 other tumor types were immunostained with INSM1, CD56, synaptophysin, and chromogranin A...

The treatment of pulmonary carcinoid has changed over the last decades. Although surgical resection is still the gold standard, minimally invasive endobronchial procedures have emerged as a parenchyma sparing alternative for tumors located in the central airways. This review was performed to identify the optimal treatment strategy for pulmonary carcinoid, with a particular focus on the feasibility and outcome of parenchyma sparing techniques versus surgical resection. A systematic review of the literature was carried out using MEDLINE, Embase and the Cochrane databases, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement...

<br>Serotonin, a biologically active amine, is related to carcinoid syndrome in functioning neuroendocrine tumors (NETs). Telotristat ethyl is a novel inhibitor of the tryptophan hydroxylase (TPH), a key enzyme in the production of serotonin. While its use in patients with carcinoid syndrome and uncontrolled diarrhea under somatostatin analogs (SSAs) has been recently approved, in vitro data evaluating it effectiveness are lacking. For this reason, we aimed to evaluate the effect of telotristat as monotherapy, and in combination with SSAs, on proliferation and secretion in a NET cell line model...

Incidence of endocrine cancers is rising every year. Over the last decade, evidence has accumulated that demonstrates the anti-cancer effects of an anti-diabetic drug - metformin - in endocrine malignancies. We performed a literature review utilizing the Pubmed, Medline and clinicaltrials.gov databases using the keyword "metformin" plus the following terms: "thyroid cancer," "thyroid nodules," "parathyroid," "hyperparathyroidism," "adrenal adenoma," "Cushing syndrome," "hyperaldosteronism," "adrenocortical cancer," "neuroendocrine tumor (NET)," "pancreatic NET (pNET)," "carcinoid," "pituitary adenoma," "pituitary neuroendocrine tumor (PitNET)", "prolactinoma," "pheochromocytoma/paraganglioma...
