Background: Several meta-analyses have reported quantitative data about the diagnostic performance, the prognostic value, the impact on management and the safety of positron emission tomography (PET) including related hybrid modalities (PET/CT or PET/MRI) using different radiopharmaceuticals in patients with neuroendocrine neoplasms. We performed an umbrella review of published meta-analyses to provide an evidence-based summary.
Methods: A comprehensive literature search of meta-analyses listed in PubMed/MEDLINE and Cochrane Library databases was carried out (last search date: 30 June 2021).
Results: Thirty-four published meta-analyses were selected and summarized. About the diagnostic performance: Ga-SSA PET yields high diagnostic performance in patients with NETs and PGL; F-FDOPA PET yields good diagnostic performance in patients with intestinal NETs, PGL, NB, being the best available PET method in detecting rMTC; Ga-exendin-4 PET has good diagnostic accuracy in detecting insulinomas; F-FDG PET has good diagnostic performance in detecting aggressive neuroendocrine neoplasms. About the prognostic value: Ga-SSA PET has a recognized prognostic value in well-differentiated NETs, whereas F-FDG PET has a recognized prognostic value in aggressive neuroendocrine neoplasms. A significant clinical impact of Ga-SSA PET and related hybrid modalities in patients with NETs was demonstrated. There are no major toxicities or safety issues related to the use of PET radiopharmaceuticals in patients with neuroendocrine neoplasms.
Conclusions: Evidence-based data support the use of PET with different radiopharmaceuticals in patients with neuroendocrine neoplasms with specific indications for each radiopharmaceutical.

Managing recurrent thymic epithelial tumors after resection: outcomes and role of re-resection.

Thymic epithelial tumors (TETs) are rare neoplasms that include thymomas, thymic carcinomas (TCs), and thymic neuroendocrine neoplasms (TNENs). These three tumor categories differ in aggressiveness, the incidence of recurrence after resection, the pattern of recurrence, and survival outcomes. Owing to the tumor's rarity, randomized trials have not been performed in the initial treatment setting.

Methods: This study aims to compare the prognostic outcomes of NEC and MiNEN by analyzing the clinicopathological features of these diseases and exploring factors affecting progression after radical surgery. Additionally, we employed whole-exome sequencing to investigate the molecular mechanisms influencing the prognosis of both conditions.

Neuroendocrine tumors (NENs) originate from neuroendocrine cells and predominantly occur in the gastrointestinal tract, lungs, and pancreas. Although the liver is commonly involved in NEN metastasis, primary hepatic neuroendocrine tumors (PHNETs) are rare. Herein, we report a case of a 52-year-old female who presented with slowly enlarging, cystic, multiple PHNETs.

Head-to-Head Comparison of 68Ga-FAPI-04 and 68Ga-DOTA-TATE PET/CT in Recurrent Medullary Thyroid Cancer.

February 2025
From the Department of Nuclear Medicine.
Purpose: We aimed to compare the diagnostic performance of 68Ga-FAPI-04 (FAPI) in comparison to 68Ga-DOTATATE (SSTR) PET/CT for patients presenting with recurrent medullary thyroid carcinoma (MTC).
Patients And Methods: Sixteen MTC patients with elevated calcitonin levels (>150 pg/mL) underwent FAPI and SSTR PET/CT. Two nuclear medicine physicians evaluated all images, categorizing lesions into locoregional metastases, mediastinal lymph nodes (LNs), liver, and bone metastases.
