Division of Hematology & Oncology, Roswell Park Comprehensive Cancer Center, University at Buffalo School of Medicine, Buffalo, NY 14203, USA.

Neuroendocrine tumors (NETs) are a group of malignancies that originated from neuroendocrine cells, with the most common sites being lungs and the gastrointestinal tract. Lung NETs comprise 25% of all lung malignancies. Small cell lung cancer is the most common form of lung NETs, and other rare forms include well-differentiated typical carcinoids (TCs) and poorly differentiated atypical carcinoids (ACs). Read More

[Neoendocrine carcinoma of the esophagus: report of a case].

Rev Gastroenterol Peru 2018 Jul-Sep;38(3):293-296

Escuela de Medicina, Universidad Peruana de Ciencias Aplicadas. Lima, Perú; Departamento de Medicina Interna, Hospital Nacional Hipólito Unanue. Lima, Perú.

Neuroendocrine carcinoma of esophagus represents less than 2% of cases of cancer of the esophagus. This presentation is extremely unusual, as this type of carcinoma typically presents with greater frequency in bronchopulmonary regions. The symptoms are usually associated with esophageal obstruction and include odynophagia, dysphagia and weight loss and are not usually associated with Carcinoid syndrome. Read More

Octreotide SC depot in patients with acromegaly and functioning neuroendocrine tumors: a phase 2, multicenter study.

Cancer Chemother Pharmacol 2018 Dec 8. Epub 2018 Dec 8.

Endocrinology, DiMI and CEBR, University of Genoa, Genoa, Italy.

Purpose: Octreotide SC depot is a novel, ready-to-use formulation administered via a thin needle.

Carcinoid tumors of the thymus and Cushing's syndrome: Clinicopathologic features and current best evidence regarding the cell of origin of these unusual neoplasms.

Ann Diagn Pathol 2018 Nov 22;38:71-79. Epub 2018 Nov 22.

Department of Pathology and Laboratory Medicine, Cedars-Sinai Medical Center, Los Angeles, CA, United States of America.

It is uncertain whether thymic neuroendocrine tumors (NET) associated with Cushing's syndrome (CS) produce corticotropin-releasing hormone (CRH) and adrenocorticotropin hormone (ACTH) and whether the thymus contains ACTH and/or CRH cells that could originate NET. The clinicopathologic features of 5 typical (TC) and 6 atypical carcinoids (ATC), 10 additional non-neoplastic thymi, 6 adrenal glands with bilateral nodular hyperplasia and 8 adrenal cortical adenomas were reviewed. Representative slides were immunostained for ACTH and CRH. Read More

Clinicopathologic profiling of lung carcinoids with a Ki67 index greater than 20.

Neuroendocrinology 2018 Nov 28. Epub 2018 Nov 28.


The clinicopathological features of lung neuroendocrine neoplasms (NEN) with a high proliferative index at the border area between atypical carcinoid and neuroendocrine carcinoma, have not been investigated so far. The aim of this study was, therefore, to search for lung NENs, which are well-differentiated but show Ki67 values that overlap with those of poorly differentiated NENs (PD-NENs). Resected lung NENs from 244 Japanese patients were reviewed and Ki67 index was assessed in all tumors. Read More

Metastatic thymic carcinoid responds to chemoradiation and octreotide: A case report.

Medicine (Baltimore) 2018 Nov;97(47):e13286

Department of Oncology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, China.

Rationale: Thymic carcinoids are a rare type of malignant neuroendocrine tumors which have a poor prognosis due to their distant metastasis, invasive behaviour, and postoperative recurrence. Surgical resection is still the fundamental mode for treating thymic carcinoids. Here, we report the rapid shrinkage of an atypical thymic carcinoid with multiple metastases following chemoradiation plus octreotide as a first-line therapy PATIENT CONCERNS:: A 39-year-old Chinese man presented with chest tightness, dyspnea with a history of lumbago and untreated malignant thymoma.

Enchondroma of Tibia as Potential False-positive Finding on 68Ga-DOTATOC PET/CT Scan.

Clin Nucl Med 2019 Jan;44(1):e57-e59

From the Molecular Imaging and Therapy Service, Department of Radiology, Memorial Sloan Kettering Cancer Center, New York, NY.

A 70-year-old man with a history of carcinoid tumor of small bowel was referred for Ga-DOTATOC study to evaluate the extent of disease. PET/CT scan revealed known metastatic disease in the liver, with other sites of involvement including pancreas, peritoneum, and bones. In addition, moderately intense uptake was noted in proximal right tibia and further correlation on CT showed metaphyseal lesion with "rings and arcs" calcification suggestive of enchondroma.

Distinct Imaging Characteristics of Different Metastases From Primary Prostate Adenocarcinoma and Rectal Carcinoid Tumor on 18F-Fluciclovine and 68Ga-DOTATATE PET/CT.

Clin Nucl Med 2019 Jan;44(1):83-84

Department of Nuclear Medicine, Tianjin Medical University Cancer Institute and Hospital, Tianjin, China.

A 71-year-old man with history of prostate cancer is evaluated for rising prostate-specific antigen. The patient also has a history of rectal well-differentiated neuroendocrine tumor. On F-fluciclovine PET/CT, 2 retroperitoneal lymph nodes exhibited intense fluciclovine avidity, whereas one enlarged perirectal lymph node only showed background uptake. Read More

Resection of primary tumor may prolong survival in metastatic gastroenteropancreatic neuroendocrine tumors.

Surgery 2018 Oct 23. Epub 2018 Oct 23.

Rush University Medical Center, Department of Surgery, Chicago IL. Electronic address:

Background: Patients with gastroenteropancreatic neuroendocrine tumors often present with stage IV disease. Primary tumor resection in these patients remains controversial. Herein, we studied the impact of primary tumor removal, identified variables associated with prolonged survival for each neuroendocrine tumor subtype, and determined factors that influence surgeons to perform primary tumor resection.

Report of metastatic ileal neuroendocrine tumor to the submandibular gland.

Int J Surg Case Rep 2018 Oct 19;53:1-4. Epub 2018 Oct 19.

Division of Otolaryngology - Head & Neck Surgery, Department of Surgery, Dalhousie University, Halifax, Nova Scotia, Canada.

Background: Neuroendocrine tumors (NETs) of small intestinal origin are generally slow-growing tumors with a relatively high propensity for metastases to surrounding organs and lymphatic tissue. We present the first case of an ileal NET metastasizing to the submandibular gland in a woman with metastatic carcinoid syndrome.

Case Presentation: A 55-year-old female presented with a four-month history of a palpable, left-sided neck mass. Read More
