Abstract
Evaluation of an incidentally discovered indeterminate thyroid nodule (TN) in a previously healthy 59-year female led to diagnosis of thyroid paraganglioma (TPGL) and subsequently hereditary succinate dehydrogenase complex subunit D (SDHD)-related multifocal head and neck paragangliomas (PGLs). An ultrasound-guided fine needle aspiration (FNA) biopsy of the 1.7-cm TN was nondiagnostic and core biopsy was suspicious for papillary thyroid carcinoma. Pathology slides reviewed at tertiary center showed neuroendocrine neoplasm consistent with PGL. Her 24-hour urinary catecholamines and metanephrines were normal. Given the diagnosis of TPGL, genetic testing was recommended, which identified a pathogenic variant in SDHD (c.242C > T(p.P81L). Gallium-68-DOTATATE PET/CT revealed multifocal areas of increased somatostatin receptor expression from the skull base to thoracic inlet. Magnetic resonance imaging of the brain/neck showed multiple PGLs (right jugular, carotid, thyroid, left vagal, left level II, and superior mediastinal), all measured up to 1.7 cm. The right jugular PGL was treated with external beam radiation therapy of 3000 cGy. All PGLs remained stable and asymptomatic at 22-month follow-up imaging. TPGL should be considered in the differential diagnosis of a hypervascular TN in patients with SDHx-related pheochromocytoma-PGL syndromes and when such lesions with indeterminate cytology are encountered in patients with no known history of SDHx-mutation or syndrome.

Abstract
OBJECTIVE Thyroid-originated paragangliomas are very uncommon, and there is a lack of established guidelines regarding their management. METHODS A case study was presented, and a review of the literature was conducted. RESULTS Diagnosing a paraganglioma requires multiple diagnostic methods, including a 24-h measurement of metanephrines or catecholamines, anatomical imaging using magnetic resonance or computed tomography (CT) scans, and functional imaging using metaiodobenzylguanidine or 18F-DOPA PET/CT scans. Additionally, with the presence of somatostatin receptors on paragangliomas, the use of octreotide scans such as a 68Ga DOTATATE PET/CT scan is expected to increase soon. The primary treatment for laryngeal paragangliomas is surgical intervention aimed at achieving optimal tumor removal while retaining the highest possible level of laryngeal function. One should not do elective neck dissection given the low risk of metastasis and recurrence. Although the rate of recurrence and metastasis for paragangliomas is low, continued monitoring through clinic visits, biochemical testing, and imaging is still necessary. Furthermore, follow-up efforts should also consider genetic testing of the critical genes associated with paragangliomas. CONCLUSION Although there is still debate regarding the existence of thyroid paraganglioma, it can nonetheless be classified as a subtype of laryngeal paragangliomas. All hypervascular thyroid nodules require the consideration of thyroid-associated paragangliomas.

Endovascular Embolization as a Stand-Alone Treatment of Head and Neck Paragangliomas with Long-Term Tumor Control. AJNR Am J Neuroradiol 2024:ajnr.A8328. [PMID: 38719606 DOI: 10.3174/ajnr.a8328] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Accepted: 04/30/2024] [Indexed: 08/03/2024]
Abstract
BACKGROUND AND PURPOSE The impact of therapeutic embolization as a stand-alone treatment of head and neck paragangliomas considered surgically high-risk remains insufficiently understood. The aim of this study was to investigate the procedural risks and long-term volumetric development in head and neck paragangliomas with high surgical risk following therapeutic endovascular embolization as a stand-alone treatment. MATERIALS AND METHODS A retrospective database review of patients who underwent endovascular embolization as primary treatment for head and neck paragangliomas lacking appropriate curative treatment options at our institution (from January 2000 to February 2023) was conducted. Tumor volumetric analyses were performed before embolization and during follow-up. To assess the changes in tumor volume over time, the measurements were performed after embolization, first at 6 months and then on a yearly basis up to 6 years (mean follow-up time was 33.7 ± 24.4 months). Subgroup analyses were conducted for vagal and jugular/jugulotympanic paragangliomas. RESULTS A total of 32 head and neck paragangliomas in 28 patients (mean age, 56.1 years ± 16.5 [standard deviation]; 18 female) with therapeutic embolization as stand-alone treatment were evaluated, of which 11 were vagal paragangliomas, 15 jugular/jugulotympanic paragangliomas, and 6 carotid body tumors. After a mean follow-up duration of 33.7 ± 24.4 months, tumor control was achieved in 75%, with significant median tumor volume reduction at 6 months (P = .02, n = 21). Vagal paragangliomas responded the most to embolization with a significantly decreased median volume from 22.32 cm3 to 19.09 cm3 (P = .008, n = 8). Transient complications occurred in 3.4%. CONCLUSIONS Therapeutic embolization as a stand-alone treatment offers a low-risk control of tumor growth in surgically high-risk lesions, with a significant reduction in tumor volume after treatment. Among the different subtypes, vagal paragangliomas exhibited the strongest and longest regression of the tumor volume.

Abstract
Exosomes, as a class of small extracellular vesicles closely related to the biological behavior of various types of tumors, are currently attracting research attention in cancer diagnosis and treatment. Regarding cancer diagnosis, the stability of their membrane structure and their wide distribution in body fluids render exosomes promising biomarkers. It is expected that exosome-based liquid biopsy will become an important tool for tumor diagnosis in the future. For cancer treatment, exosomes, as the "golden communicators" between cells, can be designed to deliver different drugs, aiming to achieve low-toxicity and low-immunogenicity targeted delivery. Signaling pathways related to exosome contents can also be used for safer and more effective immunotherapy against tumors. Exosomes are derived from a wide range of sources, and exhibit different biological characteristics as well as clinical application advantages in different cancer therapies. In this review, we analyzed the main sources of exosomes that have great potential and broad prospects in cancer diagnosis and therapy. Moreover, we compared their therapeutic advantages, providing new ideas for the clinical application of exosomes.

Abstract
The mechanisms of the pathogenesis of neck paraganglioma (PGL) and the possible role of mast cells (MCs) in its development and metastasis are still poorly understood. We analyzed MCs' morphologic characterization, activation, and the properties of their cytoplasmic/released granules in PGLs, using light and transmission electron microscopy. Paragangliomas showed a large tumor-associated MC population both in the connective tissue layers of the tumor and between the tumor cells. Notably, MCs were presented by a high expression of specific proteases, size variation, polymorphism, and variable ultrastructural phenotype of granules. A massive number of granules were released surrounding the degranulated MCs while the integrity of MC membrane was maintained. Granules were electron-dense with or without a membrane, ranging from 0.2 to 0.8 μm in diameter. MC plasmalemma was not found at the site of MC-collagen fibrils contact, whereas the secretome and fibrils were directly contacted. We observed direct and mediator-based interactions between MCs and paraganglioma cells. The latter preserved their membrane integrity when MC granules were not in proximity. The effects of the MC secretome on the paraganglioma microenvironment demonstrated its pathogenetic role in tumor progression and allow its application to new diagnostic criteria and the development of protocols for personalized therapy. RESEARCH HIGHLIGHTS: Ultrastructural analysis reveals novel regulatory effects of mast cells via diverse secretory pathways on the pathogenesis of parasympathetic paraganglioma, including fibrous extracellular matrix remodeling and mediator-based interactions between MCs and cells of the tumor microenvironment.

The Value of PET/CT in Particle Therapy Planning of Various Tumors with SSTR2 Receptor Expression: Comparative Interobserver Study. Cancers (Basel) 2024; 16:1877.

Abstract
The overexpression of somatostatin receptor type 2 (SSTR2) is a property of various tumor types. Hybrid imaging utilizing [68Ga]1,4,7,10-tetraazacyclododecane-1,4,7,10-tetra-acetic acid (DOTA) may improve the differentiation between tumor and healthy tissue. We conducted an experimental study on 47 anonymized patient cases including 30 meningiomas, 12 PitNET and 5 SBPGL. Four independent observers were instructed to contour the macroscopic tumor volume on planning MRI and then reassess their volumes with the additional information from DOTA-PET/CT. The conformity between observers and reference volumes was assessed. In total, 46 cases (97.9%) were DOTA-avid and included in the final analysis. In eight cases, PET/CT additional tumor volume was identified that was not detected by MRI; these PET/CT findings were potentially critical for the treatment plan in four cases. For meningiomas, the interobserver and observer to reference volume conformity indices were higher with PET/CT. For PitNET, the volumes had higher conformity between observers with MRI. With regard to SBGDL, no significant trend towards conformity with the addition of PET/CT information was observed. DOTA PET/CT supports accurate tumor recognition in meningioma and PitNET and is recommended in SSTR2-expressing tumors planned for treatment with highly conformal radiation.

Abstract
Carotid body tumor (CBT) is a rare neck tumor located at the adventitia of the common carotid artery bifurcation. The prominent pathological features of CBT are high vascularization and abnormal proliferation. However, single-cell transcriptome analysis of the microenvironment composition and molecular complexity in CBT has yet to be performed. In this study, we performed single-cell RNA sequencing (scRNA-seq) analysis on human CBT to define the cells that contribute to hypervascularization and chronic hyperplasia. Unbiased clustering analysis of transcriptional profiles identified 16 distinct cell populations including endothelial cells (ECs), smooth muscle cells (SMCs), neuron cells, macrophage cells, neutrophil cells, and T cells. Within the ECs population, we defined subsets with angiogenic capacity plus clear signs of later endothelial progenitor cells (EPCs) to normal ECs. Two populations of macrophages were detectable in CBT, macrophage1 showed enrichment in hypoxia-inducible factor-1 (HIF-1) and as well as an early EPCs cell-like population expressing CD14 and vascular endothelial growth factor. In addition to HIF-1-related transcriptional protein expression, macrophages1 also display a neovasculogenesis-promoting phenotype. SMCs included three populations showing platelet-derived growth factor receptor beta and vimentin expression, indicative of a cancer-associated fibroblast phenotype. Finally, we identified three types of neuronal cells, including chief cells and sustentacular cells, and elucidated their distinct roles in the pathogenesis of CBT and abnormal proliferation of tumors. Overall, our study provided the first comprehensive characterization of the transcriptional landscape of CBT at scRNA-seq profiles, providing novel insights into the mechanisms underlying its formation.

Abstract
OPINION STATEMENT Temporal bone paragangliomas (TBPs) are indolent, classically benign and highly vascular neoplasms of the temporal bone. There are two types of TBPs, tympanomastoid paragangliomas (TMPs) and tympanojugular paragangliomas (TJPs). The most common symptoms are hearing loss and pulsatile tinnitus. Diagnostic workup, besides conventional physical and laboratory examinations, includes biochemical testing of catecholamine and genetic testing of SDHx gene mutations as well as radiological examination. Although surgery is traditionally the mainstay of treatment, it is challenging due to the close proximity of tumor to critical neurovascular structures and thus the high risk of complications, especially in patients with advanced lesions. Radiotherapy and active surveillance have been increasingly recommended for selected patients. Decision on treatment should be made comprehensively. Curative effect depends on various factors. Long-term follow-up with clinical, laboratory, and radiological examinations is essential for all patients.

Abstract
OBJECTIVE To compare the differences in the short-term recovery from neurological symptoms (SRN) (≤ 6 months) and clinical characteristics of patients with different Shamblin classifications carotid body tumor (CBT) resection and to analyze the risk factors affecting SRN after surgery. METHODS Patients who underwent CBT resection between June 2018 and September 2022 were recruited. Perioperative factors and indicators of the nature of the tumor were recorded. The risk factors affecting SRN after CBT resection were analyzed using logistic regression analysis. RESULTS Eighty-five patients (43.86 ± 12.7 years, 46 females) were included, 40 (47.06%) of whom exhibited SRN. Univariate logistic regression showed that preoperative symptoms, surgical side, bilateral posterior communicating artery (PcoA) opening, some indicators of tumor size, operative/anesthesia time, and Shamblin III classification were correlated with postoperative neurological prognosis (all p < 0.05). After adjusting for confounders, preoperative symptoms (OR, 5.072; 95% CI 1.027-25.052; p = 0.046), surgical side (OR, 0.025; 95% CI 0.003-0234; p = 0.001), bilateral PcoA opening (OR, 22.671; 95% CI 2.549-201.666; p = 0.005), distance from the tip of the C2 dens to the superior aspect (dens-CBT) (OR, 0.918; 95% CI 0.858-0.982; p = 0.013) and Shamblin III classification (OR, 28.488; 95% CI 1.986-408.580; p = 0.014) were correlated with postoperative neurological symptom recovery. CONCLUSION Preoperative symptoms, surgical side (right), bilateral PcoA opening, a short dens-CBT and Shamblin III classification are risk factors affecting SRN after CBT resection. Early resection is recommended for small-volume CBTs without neurovascular compression or invasion to obtain SRN.

Abstract
OBJECTIVE Patients with head and neck paragangliomas who are positive for the SDHD p.Pro81Leu (P81L) mutation are thought to have a distinct phenotype from other SDHx mutations, but few studies have focused on this mutation. The objective of this study was to determine the hazard of developing a second primary, metastatic, or recurrent paraganglioma in SDHx patients with or without P81L. STUDY DESIGN Retrospective chart review of 60 patients with head and neck paragangliomas and genetic testing, followed for a median of 9 years. SETTING Single academic medical center. METHODS Univariable Cox proportional hazards regression evaluated second primary and recurrent paragangliomas in patients with SDHD P81L, SDHx non-P81L, and nonhereditary paraganglioma. RESULTS This series comprised 31 patients without SDHx, 14 with SDHD P81L, and 15 with other SDHx mutations. At a median 9 years of follow-up, corporal (not head and neck) second primary paragangliomas occurred in 31% of patients with SDHx non-P81L mutations, compared with 0% and 4% of patients with SDHD P81L and without SDHx mutations, respectively. Second corporal paragangliomas were more likely in patients with SDHx non-P81L mutations than in those without a mutation (hazard ratio = 5.461, 95% confidence interval: 0.596-50.030, p = .13). CONCLUSION This is the first study to report a lower likelihood of corporal tumors for patients with head and neck paragangliomas with SDH mutations positive for P81L. Larger studies are needed to determine if head and neck paraganglioma patients with P81L qualify for less intensive imaging surveillance to screen for second primary paragangliomas outside the head and neck.

Abstract
Paragangliomas are rare, slow-growing, hypervascular, catecholamine-secreting neuroendocrine tumors arising from the paraganglia. Paragangliomas are rarely found in the head and neck and are typically benign, presenting as a painless, slow-growing mass. Surgical extirpation in combination with long-term surveillance has been long regarded as the standard of care; however, the advances in imaging, radiation therapy, and embolization techniques have improved diagnostic and therapeutic modalities. We present a case of an 87-year-old female who had previously undergone resection of a paraganglioma in 1998, with no evidence of disease in 2002. Eighteen years later, the patient presented to the clinic with otogenic complaints. Imaging showed an expansive mass from the jugular foramen with bone destruction and opacification within the ear canal. The patient opted for observation. The patient eventually presented to the emergency room with neurologic manifestations. Imaging showed a cerebellar abscess prompting emergency drainage. Intraoperative cultures grew Prevotella loescheii and S. intermedius, and the patient was started on 6 weeks of IV antibiotic therapy. Debulking of the paraganglioma was performed followed several months by mastoid and ear canal obliteration; however, the patient experienced complications, including dehiscence of the external auditory canal and Clostridium difficile infection. The patient was eventually treated successfully, marked by a reduction in complaints, a return to baseline activities, and imaging showing no increase in tumor size.

Abstract
Non-syndromic carotid body paragangliomas (CBPs) are the most common head and neck CBPs. Malignant transformation or symptomatic presentation is rare, but patients may occasionally endorse tinnitus, cranial nerve (CN) deficits, and ear pulsations. Historically, treatment of CBP was primarily through surgical intervention, which predisposed patients to CN deficits and significant blood loss due to the neurovascular structures in close proximity to these tumors. More recently, the utilization of pre-treatment embolization and radiotherapy has allowed for the reduction in treatment morbidity. Stereotactic radiosurgery (SRS) and external beam radiotherapy (EBRT) have been investigated as alternatives to traditional surgical intervention, with a documented reduction in the incidence of postoperative morbidity. While several retrospective studies and meta-analyses compare outcomes following surgical and traditional radiotherapeutic interventions, currently no literature exists regarding the potential utility of fast neutron therapy in treating this disease. In this case report, we highlight a patient with a non-syndromic CBP treated with pre-treatment embolization and fast neutron therapy, review the post-treatment course, and present a review of the extant literature on the subject.
