Head and neck paragangliomas (HNPGLs) are rare and have high rates of genetic mutations. We conducted a retrospective review of 187 patients with 296 PGLs diagnosed between 1974 and 2023. The mean age of diagnosis was 48.

Background: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are a diverse family of cancers that occur within the gastrointestinal tract and pancreas. Peptide receptor radionuclide therapy (PRRT) via 177Lu-DOTATATE is a newer therapeutic option for certain patients with somatostatin receptor-positive GEP-NETs.

Objectives: This review informs on how oncology nurses treating patients with GEP-NETs receiving PRRT using 177Lu-DOTATATE can facilitate care.

Article Synopsis
  • Urinary bladder paraganglioma (UBPGL) is a rare tumor, with a study analyzing 110 patients revealing a median diagnosis age of 50 years and a median tumor size of 2 cm.
  • Only 34% of patients were diagnosed prior to surgery, highlighting a need for improved diagnostic methods, and 25% required additional treatments post-surgery.
  • The study found that younger age, larger tumor size, and higher catecholamine levels were linked to a greater risk of metastases, and patients with synchronous metastases had significantly higher disease-specific mortality.

Purpose: Neuroendocrine tumors (NETs) negatively impact patients' quality of life. Octreotide long-acting release (LAR) and lanreotide depot are somatostatin analogs (SSAs) approved to treat NETs. The study objective was to explore SSA treatment experiences and preferences of patients with NETs.

Importance: Peptide receptor radionuclide therapy (PRRT) is approved in the US for treatment of gastroenteropancreatic neuroendocrine tumors (NETs), but data on PRRT outcomes within US populations remain scarce.

Objective: To analyze the first 2 years of PRRT implementation at a US-based NET referral center.

Design, Setting, And Participants: This cohort study was conducted using medical records of patients with metastatic NET receiving PRRT from 2018 through 2020 in a NET program at a tertiary referral center.

Currarino syndrome (CS) is an autosomal dominant syndrome caused by mutations in MNX1 and characterized by anorectal abnormalities, partial sacral agenesis, and presacral masses. The presacral masses are typically benign; however, malignant degeneration can occur, and presacral neuroendocrine tumors (NETs) have been reported in six cases. We report three individuals from two families affected by CS in which multiple individuals developed presacral NETs.

Purpose: Minimal data exist regarding the efficacy of screening protocols for individuals with SDHx germline pathogenic variants with hereditary paraganglioma-pheochromocytoma syndrome. This study aimed to evaluate the SDHx-related tumor detection rate in individuals undergoing clinical screening protocols.

Methods: A multicenter retrospective longitudinal observational study was conducted.

Background: Peptide receptor radionuclide therapy (PRRT) is effective for treating midgut neuroendocrine tumors (NETs); however, incorporation of PRRT into routine practice in the U.S. is not well studied.

Background: Small (< 2 cm) and diminutive (< 1 cm) rectal neuroendocrine tumors (RNETs) are often described as indolent lesions. A large single-center experience was reviewed to determine the incidence of metastasis and the risk factors for its occurrence.

Methods: Cases of RNET between 2010 and 2017 at a single institution were retrospectively reviewed.

Diarrhea is often a presenting symptom in patients with neuroendocrine tumors (NETs). Frequently diagnosed in advanced stages, carcinoid syndrome diarrhea negatively impacts patients' well-being and quality of life. This article will review the diagnostic work-up for neuroendocrine tumors and etiology and management of NET-related carcinoid syndrome diarrhea and provide guidance for advanced practitioners, including nurse practitioners, physician assistants, pharmacists, and dieticians, focusing on their role in patient and caregiver education regarding disease, symptom monitoring and management, development of patient-specific treatment, and survivorship plans.

Somatostatin analogues (SSAs) are widely used in the long-term treatment of neuroendocrine tumors (NETs) and have a relatively favorable safety profile. However, SSAs are associated with specific side effects that are important to monitor. Currently, there is no standardized safety monitoring protocol for health-care professionals to use as a reference when initiating patients on long-acting SSAs.

Objectives: The aim of this study was to analyze in a retrospective cohort study the outcomes of a United States-based group of metastatic neuroendocrine tumor (NET) patients who underwent peptide receptor radionuclide therapy (PRRT).

Methods: Twenty-eight patients from a single US NET Center were treated with PRRT. Toxicities were assessed using Common Terminology Criteria for Adverse Events version 4.

Background: Treatment of metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs) with peptide receptor radionuclide therapy (PRRT) is effective in retarding tumor growth. Renal dysfunction, anemia, and thrombocytopenia are well-described treatment-related toxicities. However, hepatotoxicity is not well recognized.

Objectives: Zollinger-Ellison syndrome (ZES) is characterized by hypergastrinemia and gastric acid hypersecretion resulting in peptic ulcer disease, diarrhea, and weight loss. Acid secretion can be controlled with medication, and biochemical cure is possible with surgery. Data on how these interventions affect patients' weight are lacking.

Pancreatic neuroendocrine tumors (PNETs) are rare, indolent tumors that may occur sporadically or develop in association with well-recognized hereditary syndromes, particularly multiple endocrine neoplasia type 1 (MEN-1). We previously demonstrated that the hedgehog (HH) signaling pathway was aberrantly up-regulated in a mouse model that phenocopies the human MEN-1 syndrome, Men1l/l;RipCre, and that inhibition of this pathway suppresses MEN-1 tumor cell proliferation. We hypothesized that the HH signaling pathway is similarly upregulated in human PNETs.
