Abstract
Head and neck paragangliomas (HNPGLs), rare neuroendocrine tumors that mainly arise from parasympathetic ganglia along the cranial nerves, are challenging due to anatomic origin, tendency to aggressive neurovascular and skull base infiltration, unpredictable metastatic potential, radio-chemoresistance, and risk of multiplicity. Symptoms range from mild to life threatening depending on location/size, but rarely relate to catecholamine excess. Risk factors include female sex and pathogenic germline variants in genes affecting hypoxia signaling (foremost succinate dehydrogenase genes). Diagnostic work-up relies on imaging, measurements of plasma free metanephrines/methoxytyramine, genetic testing, and pathology/immunohistochemistry. Management is tailored to patient/tumor characteristics and encompasses wait-scan, upfront surgery, debulking surgery, and radiotherapy. Presurgical embolization is recommended, except for small tympanic and tympanomasoid tumors. Presurgical stenting is required for internal carotid artery involvement, and two-stage surgery for intradural extension. Current treatments for metastatic/inoperable HNPGL are non-curative, and long-term follow-up should be recommended for all patients to monitor local recurrence and new tumors.

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
Glomus tumors (or paragangliomas) are rare, benign tumors of neuroendocrine origin that appear in tissues of paraganglionic origin. This clinical entity poses a significant treatment challenge due to its proximity to critical neurovascular structures, thus the potential of morbid functional damage caused by disease progression and/or treatment approach. While surgery remains the standard of care for such cases, there has been an increasing trend toward management with radiotherapy or close observation. Here, we present a case of a large and irregularly shaped glomus jugulotympanicum tumor that was treated with volumetric arc radiotherapy. Given the risk of cranial neuropathy with surgery, radiation was the preferred treatment modality. This case demonstrated the safety and efficacy of volumetric arc radiotherapy in the management of a large glomus tumor with a complex shape.

Abstract
Malignant carotid body tumors (MCBT) are rare and diagnosed after detection of nodal or distant metastases. This systematic review (SR) focuses on MCBT initially approached by surgery. Preferred Reporting Items for SR and Meta-Analysis (MA) guided the articles search from 2000 to 2023 on PubMed, Scopus, and Web of Science. Among 3548 papers, 132 (337 patients) were considered for SR; of these, 20 (158 patients) for MA. Malignancy rate was 7.3%, succinate dehydrogenase (SDH) mutation 17%, age at diagnosis between 4th and 6th decades, with a higher prevalence of females. MCBTs were mostly Shamblin III, with nodal and distant metastasis in 79.7% and 44.7%, respectively. Malignancy should be suspected if CBT >4 cm, Shamblin III, painful or otherwise symptomatic, at the extremes of age, bilateral, with multifocal disease, and SDHx mutations. Levels II-III clearance should be performed to exclude nodal metastases and adjuvant treatments considered on a case-by-case basis.

Abstract
Adult and paediatric patients with pathogenic variants in the gene encoding succinate dehydrogenase (SDH) subunit B (SDHB) often have locally aggressive, recurrent or metastatic phaeochromocytomas and paragangliomas (PPGLs). Furthermore, SDHB PPGLs have the highest rates of disease-specific morbidity and mortality compared with other hereditary PPGLs. PPGLs with SDHB pathogenic variants are often less differentiated and do not produce substantial amounts of catecholamines (in some patients, they produce only dopamine) compared with other hereditary subtypes, which enables these tumours to grow subclinically for a long time. In addition, SDHB pathogenic variants support tumour growth through high levels of the oncometabolite succinate and other mechanisms related to cancer initiation and progression. As a result, pseudohypoxia and upregulation of genes related to the hypoxia signalling pathway occur, promoting the growth, migration, invasiveness and metastasis of cancer cells. These factors, along with a high rate of metastasis, support early surgical intervention and total resection of PPGLs, regardless of the tumour size. The treatment of metastases is challenging and relies on either local or systemic therapies, or sometimes both. This Consensus statement should help guide clinicians in the diagnosis and management of patients with SDHB PPGLs.

Somatostatin Receptor-Directed PET/CT Can Differentiate Between Different Subtypes of Head and Neck Paragangliomas. Clin Nucl Med 2023; 48:923-927. [PMID: 37756444 PMCID: PMC10581414 DOI: 10.1097/rlu.0000000000004870] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 08/01/2023] [Indexed: 09/29/2023]
Abstract
BACKGROUND Given their neuroendocrine origin, head and neck paragangliomas (HNPGLs) can be imaged with somatostatin receptor (SSTR)-directed PET/CT. We aimed to determine whether the in vivo PET signal can differentiate between varying HNPGL subtypes. PATIENTS AND METHODS Fourteen patients with HNPGL received pretherapeutic SSTR-PET/CTs using 68 Ga-DOTATOC. Six (42.9%) patients had a jugular paraganglioma (PGL-J), 5 (35.7%) were diagnosed with carotid paraganglioma (PGL-Cs), and the remaining 3 patients (21.4%) had PGL-C with pathogenic SDHx germline variants (PGL-C-SDH). A visual and quantitative assessment of the primary tumor on SSTR-PET was performed, including SUV max and target-to-background ratio (TBR). Quantitative values were then compared between subgroups of patients affected with different HNPGL entities. RESULTS On visual assessment, all primary HNPGLs could be identified on SSTR-PET/CT. Quantification of HNPGL revealed substantially elevated SUV max in PGL-J (101.7 ± 58.5) when compared with PGL-C-SDH (13.4 ± 5.6, P < 0.05), but not when compared with PGL-C (66.7 ± 27.3, P = 0.4; PGL-C vs PGL-C-SDH, P = 0.2). TBR of PGL-J (202.9 ± 82.2), however, further differentiated between PGL-C (95.7 ± 45.4, P < 0.05) and PGL-C-SDH (20.4 ± 12.2, P < 0.01; PGL-C vs PGL-C-SDH, P = 0.3). Moreover, whole-body readout revealed metastases in 2/3 (66.7%) of PGL-C-SDH patients, with a single SSTR-expressing skeletal lesion in one subject and bipulmonary lesions in the other patient. CONCLUSIONS In patients with HNPGL, SSTR-PET/CT identified the primary and metastatic disease and provides substantially elevated TBR, indicating excellent image contrast. PET-based quantification can also differentiate between varying HNPGL subtypes.

Abstract
Paragangliomas are rare neuroendocrine tumors that arise from the extra-adrenal autonomic paraganglia, i.e., small organs consisting mainly of neuroendocrine cells that are derived from the embryonic neural crest and have the ability to secrete catecholamines. Paragangliomas can derive from either parasympathetic or sympathetic paraganglia. Most of the parasympathetic ganglia-derived paragangliomas are nonfunctional, and symptoms result from mass effect. Conversely, the sympathetic paragangliomas are functional and produce catecholamine. Although such patients could have symptoms similar to pheochromocytoma, mass effect symptoms, or non-specific symptoms, being benign tumors, they can also present with anemia, specifically iron-deficiency anemia. Considering that neoplastic pathology is chronically accompanied by moderate, normochromic, normocytic anemia, association between paragangliomas that are mostly benign but with a potential degree of malignancy and anemia is not as frequent as expected, with only 12 cases reported in the literature. We report a case of a 54-year-old female patient diagnosed with a paraganglioma of the carotid glomus accompanied by severe normochromic, normocytic anemia, which reached normal limits after excision of the paraganglioma.

Abstract
Carotid body tumors (CBTs) are rare neoplasms of the neuroectoderm accounting for 0.6% of head and neck tumors, with a 2%-12.5% risk of malignancy. While surgical resection has been associated with a high rate of neurologic and vascular complications, it remains the mainstay of treatment for malignant CBTs. We present the case of a 40-year-old female with a 5-year history of progressively enlarging right-sided neck mass, with MRI and MRA showing a Shamblin grade III CBT encasement of the internal carotid artery (ICA). Blood flow was absent in the petrous segment of ICA, with great collateralization of brain blood supply, enabling en bloc resection of the tumor with a carotid bulb and ligation of the common carotid artery (CCA) without vascular reconstruction. Further, we describe the characteristics and current management for malignant CBTs, including surgical management, pre-surgical embolization, and adjuvant radiation therapy.

Abstract
OBJECTIVE To review the epidemiology, presentation, diagnosis, and management of head and neck paragangliomas. METHODS A literature review of english language papers with focus on most current literature. RESULTS Paragangliomas (PGLs) are a group of neuroendocrine tumors that arise in the parasympathetic or sympathetic ganglia. Head and neck PGLs (HNPGLs) comprise 65% to 70% of all PGLs and account for 0.6% of all head and neck cancers. The majority of HNPGLs are benign, and 6% to 19% of all HNPGLs develop metastasis outside the tumor site and significantly compromise survival. PGLs can have a familial etiology with germline sequence variations in different susceptibility genes, with the gene encoding succinate dehydrogenase being the most common sequence variation, or they can arise from somatic sequence variations or fusion genes. Workup includes biochemical testing to rule out secretory components, although it is rare in HNPGLs. In addition, imaging modalities, such as computed tomography and magnetic resonance imaging, help in monitoring in surgical planning. Functional imaging with DOTATATE-positron emission tomography, 18F-fluorodeoxyglucose, or 18F-fluorohydroxyphenylalanine may be necessary to rule out sites of metastases. The management of HNPGLs is complex depending on pathology, location, and aggressiveness of the tumor. Treatment ranges from observation to resection to systemic treatment. Similarly, the prognosis ranges from a normal life expectancy to a 5-year survival of 11.8% in patients with distant metastasis. CONCLUSION Our review is a comprehensive summary of the incidence, mortality, pathogenesis, presentation, workup and management of HNPGLs.

Abstract
BACKGROUND Paragangliomas and extra-adrenal pheochromocytomas are uncommon neuroendocrine tumors with ubiquitous distribution. Malignant paraganglioma is a relatively rare entity. We report the treatment and pathological characteristics of a patient with malignant paraganglioma, and summarize the latest advances in the treatment of malignant paraganglioma based on a literature review.
CASE SUMMARY A 45-year-old Chinese woman presented to the hospital due to pain in the waist (right side) and right buttock, and was diagnosed as malignant paraganglioma after the placement of ureteral stent, implantation of ileus catheter, and transvaginal removal of the vaginal mass. After relief of intestinal obstruction, the patient received intravenous chemotherapy and peritoneal perfusion chemotherapy. Although her pelvic mass disease was stable, she developed multiple liver metastases and bone metastases. Due to the development of spinal cord compression, she underwent orthopedic surgery, followed by radiotherapy, and molecular targeted therapy with apatinib, but with poor disease control.
CONCLUSION Clinical management of paraganglioma is challenging for endocrinologists and oncologists. Prospective studies are required to develop standardized therapeutic strategies for malignant paragangliomas.

Abstract
BackgroundPheochromocytoma (PHEO) and paraganglioma (PGL) are relatively rare neuroendocrine tumors. The factors affecting patients with early death remain poorly defined. We aimed to study the demographic and clinicopathologic pattern and to develop and validate a prediction model for PHEO/PGL patients with early death.MethodsData of 800 participants were collected from the Surveillance Epidemiology and End Results (SEER) database as a construction cohort, while data of 340 participants were selected as a validation cohort. Risk factors considered included the year of diagnosis, age at diagnosis, gender, marital status, race, insurance status, tumor type, primary location, laterality, the presence of distant metastasis. Univariate and multivariate logistic regressions were performed to determine the risk factors. R software was used to generate the nomogram. Calibration ability, discrimination ability, and decision curve analysis were analyzed in both construction and validation cohorts.ResultsPHEO and PGL patients accounted for 54.3% (N=434) and 45.7% (N=366), respectively. More than half of tumors (N=401, 50.1%) occurred in the adrenal gland, while 16.9% (N=135) were in aortic/carotid bodies. For the entire cohort, the median overall survival (OS) was 116.0 (95% CI: 101.5-130.5) months. The multivariate analysis revealed that older age (versus age younger than 31; age between 31 and 60: OR=2.03, 95% CI: 1.03-4.03, P=0.042; age older than 60: OR=5.46, 95% CI: 2.68-11.12, P<0.001), female gender (versus male gender; OR=0.59, 95% CI: 0.41-0.87, P=0.007), tumor located in aortic/carotid bodies (versus tumor located in adrenal gland; OR=0.49, 95% CI: 0.27-0.87, P=0.015) and the presence of distant metastasis (versus without distant metastasis; OR=4.80, 95% CI: 3.18-7.23, P<0.001) were independent risk factors of early death. The predictive nomogram included variables: age at diagnosis, gender, primary tumor location, and distant metastasis. The model had satisfactory discrimination and calibration performance: Harrell’s C statistics of the prediction model were 0.733 in the construction cohort and 0.716 in the validation cohort. The calibration analysis showed acceptable coherence between predicted probabilities and observed probabilities.ConclusionsWe developed and validated a predictive nomogram utilizing data from the SEER database with satisfactory discrimination and calibration capability which can be used for early death prediction for PHEO/PGL patients.

Abstract
Head and neck paragangliomas (HNPGLs) are rare neuroendocrine tumors typically arising from nonsecretory head and neck parasympathetic ganglia. Historically thought of as aggressive tumors that warranted equally aggressive surgical intervention, evidence has emerged demonstrating that the vast majority of HNPGLs are slow growing and indolent. It is also now recognized that a large proportion of HNPGLs are hereditary with succinate dehydrogenase gene mutations typically implicated. These recent advances have led to significant changes in the way in which clinicians investigate and treat HNPGLs with most now opting for more conservative treatment strategies. However, a proportion of patients present with more aggressive disease and still require nonconservative treatment strategies. Recent studies have sought to determine in which groups of patients the morbidity associated with treatment is justified. We summarize the recent advances in the understanding and management of these tumors and we provide our recommendations regarding the management of HNPGLs.

Abstract
Paragangliomas and pheochromocytomas (PPGLs) are rare neuroendocrine tumors originating from paraganglionic tissue in many sites of the body. Most PPGLs are characterized by nonaggressive behavior but all of them have the potential to metastasize. PPGLs represent a great diagnostic dilemma as it is difficult to recognize tumors that are likely to be metastasizing; criteria of malignancy can be found both in benign and metastatic forms. This review aims to analyze the current knowledge of the nature of metastasizing PPGLs paying particular attention to head and neck paragangliomas (HNPGLs). Potential predictors of the malignancy risk for PPGLs were summarized and discussed. These data may also help in the development of diagnostic and prognostic strategies, as well as in the identification of novel potential therapeutic targets for patients with PPGLs.

Abstract
A posterior skull base lesion is an uncommon radiological finding that may be noted incidentally or during targeted imaging of patients with clinical symptoms attributable to the lesion. It may be inflammatory or neoplastic in etiology, or may simply be an anatomic variant or a "don't-touch" lesion that should not be misinterpreted as something more ominous. A systematic approach to the evaluation of the posterior skull base is therefore required in order to differentiate lesions requiring immediate attention from those requiring a less urgent course of action or none at all. This review will focus on the imaging features of pathologic conditions that are more commonly encountered in posterior skull base CT and MR examinations.

Abstract
Importance Malignant head and neck paragangliomas (HNPGLs) are rare entities, and there are limited data regarding optimal treatment recommendations to improve clinical outcomes. Objective To classify succinate dehydrogenase (SDH) germline mutations associated with malignant HNPGLs, evaluate time from diagnosis to identification of malignant tumor, describe locations of metastases and the functional status of malignant HNPGLs, and determine the role of selective neck dissection at the time of initial surgical resection. Design, Setting, and Participants A retrospective cohort study was completed of patients diagnosed with paragangliomas on various sites on the body at an academic tertiary cancer hospital between the years 1963 and 2018. A subanalysis of HNPGLs was also completed. Data regarding diagnosis, gene and mutation, tumor characteristics and location, and treatments used were reviewed between February 2017 and March 2018. Main Outcomes and Measures Mutations of SDH genes associated with benign and malignant HNPGLs, treatments used, time to the discovery of malignancy, and location of metastasis. Results Of the 70 patients included in the study, 40 (57%) were male, and the mean (SD) age was 47 (21.1) years. Of patients with tumors isolated to the head and neck, 38 (54%) had benign HNPGLs, which were associated with mutations in the genes SDH subunit B (SDHB) (n = 18; 47%), SDH subunit C (n = 2; 5%), and SDH subunit D (n = 18; 47%). Among those with malignant HNPGLs, all but 1 patient had mutations in SDHB (n = 5; 83%); 1 patient had no mutation associated with their disease. The average age at diagnosis for malignant HNPGLs was 35 years, while benign tumors were diagnosed at an average age at 36 years. All patients with malignant disease underwent surgery. Four patients were found to have metastasis at the time of selective neck dissection. Among patients with malignant HNPGLs, 5 (83%) were treated with adjuvant radiation, and 1 (17%) was treated with adjuvant chemotherapy. Conclusions and Relevance Malignant HNPGLs are rare entities that are difficult to diagnose and are typically identified by the presence of regional or distant metastasis. The results of this study found the prevalence of malignant HNPGLs to be 9%. These data suggest that it is beneficial to perform a selective neck dissection at the time of tumor excision. All patients with malignant HNPGLs but 1 had SDHB mutations.

Abstract
Metastatic pheochromocytomas and paragangliomas (MPPGs) are rare neuroendocrine tumors. Most patients present with advanced disease that is associated with manifestations of catecholamine release. Surgical resection of the primary tumor and ablative therapies of metastases-whenever possible-may improve clinical outcomes and, perhaps, lengthen the patient's overall survival. Significant steps in understanding the genetic alterations linked to MPPGs and scientific progress made on cancers that share a similar pathogenesis are leading to the recognition of potential systemic therapeutic options. Data derived from clinical trials evaluating targeted therapies such as tyrosine kinase inhibitors, radiopharmaceuticals, immunotherapy, and combinations of these will likely improve the outcomes of patients with advanced and progressive MPPGs. Exemplary of this success is the recent approval in the United States of the high-specific-activity iodine131 meta-iodine-benzylguanidine (MIBG) for patients with unresectable and progressive MPPGs that express the noradrenaline transporter. This review will discuss the therapeutic approaches for patients with MPPGs.

Abstract
INTRODUCTION Primary paraganglioma (PG) of the thyroid gland is an extremely rare neuroendocrine tumor with potential for misdiagnosis. We describe 2 cases of thyroid PG, suggest a possible diagnostic and therapeutic management strategy, and present a systematic review of the literature. CASE REPORTS Two 67-year-old women presented similarly with asymptomatic but rapidly growing thyroid nodules in which malignancy was suspected after fine needle aspiration biopsy, "THY 4" according to the 2014 SIAPEC classification, both undergoing total thyroidectomy. Unexpectedly, immunohistochemistry showed neuroendocrine cellular architecture that was negative for common markers of well-differentiated follicular neoplasms, thyroglobulin, thyroid transcription factor 1, cytokeratins and medullary thyroid cancer, calcitonin, carcinoembryonic antigen, whereas neuron-specific enolase, synaptophysin, chromogranin A, and S-100 protein were highly expressed, confirming the diagnosis of primary thyroid PG. The patients were both discharged on postoperative day 2, without any other therapy and are currently well without evidence of local recurrence of metastatic disease, after 4 years and 3 months of follow-up, respectively. DISCUSSION These are the only 2 cases of thyroid PG experienced in our center which specializes in thyroid surgery. Thyroid PG is a rare neuroendocrine neoplasm first described by Van Miert in 1964 with just over 50 cases reported in the literature. Our experience is concordant with the literature that the diagnosis of the primary PG of the thyroid is challenging, due to its low prevalence and the cytologic and histopathologic similarities with other more frequently diagnosed benign and malignant thyroid tumors. Immunohistochemistry is required for definitive diagnosis but gross tumor characteristics are also helpful for diagnosis. Surgical resection is the recommended standard treatment.

Abstract
BACKGROUND Paragangliomas are neuroendocrine neoplasms that arise from the extra-adrenal paraganglia of the autonomic nervous system. Approximately 3% of all paragangliomas occur in the head and neck region. Most reported cases are benign and unilateral. We present here a rare case of bilateral malignant paragangliomas. CASE DESCRIPTION A 28-year-old woman presented to our department with a 10-year history of bilateral neck swelling. Physical examination showed bilateral neck masses with obvious pulsation. Enhanced CT revealed two irregular solid nodules, located in the left and right carotid artery bifurcation, respectively. Carotid artery angiography showed compression of the internal and external carotid arteries by the tumors on both sides. Upon diagnosis of the bilateral carotid body tumors, preoperative embolization was performed. The left-side lesion as well as the lymph nodes were resected and a diagnosis of malignant paraganglioma with lymph node metastasis was made. Genetic studies have shown that familial paragangliomas are associated with germline mutation of succinate dehydrogenase subunits SDHD on 11q23. She was treated with 50-Gy radiotherapy, and a subsequent CT scan performed two years later showed that the right-side lesion was unchanged. She was symptom-free as of the last follow-up. CONCLUSIONS The rarity of bilateral malignant paragangliomas makes their management clinically challenging. The primary management of a recognized malignancy should be directed toward complete surgical removal of the primary tumor and regional lymph nodes. Postoperative radiation is beneficial in slowing the progression of residual disease.

Abstract
Phaeochromocytoma and paraganglioma (PHEO/PGL) are rare tumours with an estimated annual incidence of 3 per million. Advances in molecular understanding have led to the recognition that at least 30-40% arise in the setting of hereditary disease. Germline mutations in the succinate dehydrogenase genes SDHA, SDHB, SDHC, SDHD and SDHAF2 are the most prevalent of the more than 19 hereditary genetic abnormalities which have been reported. It is therefore recommended that, depending on local resources and availability, at least some degree of genetic testing should be offered to all PHEO/PGL patients, including those with clinically sporadic disease. It is now accepted that that all PHEO/PGL have some metastatic potential; therefore, concepts of benign and malignant PHEO/PGL have no meaning and have been replaced by a risk stratification approach. Although there is broad acceptance that certain features, including high proliferative activity, invasive growth, increased cellularity, large tumour nests and comedonecrosis, are associated with an increased risk of metastasis, it remains difficult to predict the clinical behaviour of individual tumours and no single risk stratification scheme is endorsed or in widespread use. In this review, we provide an update on advances in the pathology and genetics of PHEO/PGL with an emphasis on the changes introduced in the WHO 2017 classification of endocrine neoplasia relevant to practising surgical pathologists.

Abstract
OBJECTIVE The outcomes of patients with metastatic phaeochromocytoma (PHEO) and paraganglioma (PGL) are unclear. We performed a systematic review and meta-analysis of baseline characteristics and mortality rates of patients with metastatic PHEO and PGL (PPGL). DESIGN Ovid MEDLINE In-Process & Other Non-Indexed Citations, Ovid MEDLINE, Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, Scopus, Web of Science, and references of key articles were searched from inception to 2016. PATIENTS Studies comprised ≥20 patients with metastatic PPGL and reported baseline characteristics and follow-up data. MEASUREMENTS Reviewers extracted standardized data and assessed risk of bias using a modified Newcastle-Ottawa tool. Random-effects meta-analysis was used to pool event rates across studies. RESULTS Twenty retrospective noncomparative studies reported on 1338 patients with metastatic PHEO (685/1296, 52.9%) and PGL (611/1296, 47.1%), diagnosed at a mean age of 43.9 ± 5.2 years. Mean follow-up was 6.3 ± 3.2 years. Of 532 patients with reported data, 40.4% had synchronous metastases. Five-year (7 studies, n = 738) and 10-year (2 studies, n = 55) mortality rates for patients with metastatic PPGL were 37% (95% CI, 24%-51%) and 29% (95% CI, 17%-42%), respectively. Higher mortality was associated with male sex (RR 1.50; 95% CI, 1.11-2.02) and synchronous metastases (RR 2.43; 95% CI, 1.01-5.85). CONCLUSIONS Available low-quality evidence from heterogeneous studies suggests low mortality rates of patients with metastatic PPGL. Male sex and synchronous metastases correlated with increased mortality. The outcomes of patients with metastatic PPGL have been inadequately assessed, indicating the need for carefully planned prospective studies.

Abstract
CONTEXT Malignant pheochromocytoma (PHEO) and paraganglioma (PGL) are rare and knowledge of the natural history is limited. OBJECTIVE We aimed to describe baseline characteristics and outcomes of patients with malignant PHEO and PGL (PPGL) and to identify predictors of shorter survival. DESIGN Retrospective review of patients with malignant PPGL evaluated from 1960 to 2016. SETTING Referral center. PATIENTS The group comprised 272 patients. MAIN OUTCOME MEASURES Baseline description, survival outcomes, and predictors of shorter survival were evaluated in patients with rapidly progressive (n = 29) and indolent disease (n = 188). RESULTS Malignant PPGL was diagnosed at a median age of 39 years (range, 7 to 83 years), with synchronous metastases in 96 (35%) patients. In 176 (65%) patients, metastases developed at a median of 5.5 years (range, 0.3 to 53.4 years) from the initial diagnosis. Median follow-up was 8.2 years (range, 0.01 to 54.1 years). Median overall and disease-specific survivals were 24.6 and 33.7 years, respectively. Shorter survival correlated with male sex (P = 0.014), older age at the time of primary tumor (P = 0.0011), synchronous metastases (P < 0.0001), larger primary tumor size (P = 0.0039), elevated dopamine (P = 0.0195), and not undergoing primary tumor resection (P < 0.0001). There was no difference in the type of primary tumor or presence of SDHB mutation. CONCLUSIONS The clinical course of patients with malignant PPGL is remarkably variable. Rapid disease progression is associated with male sex, older age at diagnosis, synchronous metastases, larger tumor size, elevated dopamine, and not undergoing resection of primary tumor. An individualized approach to patients with metastatic PPGL is warranted.

Abstract
Malignant carotid body tumors are rare, with spread of the tumor mostly noted in regional lymph nodes. Vertebral metastases are an exceedingly rare presentation, only reported in isolated case reports, and present a diagnostic and management challenge. A case of widespread vertebral metastasis, presenting with myelopathy, from a carotid body tumor is discussed in this paper, along with management strategies.

Abstract
Germline variants in subunit D of the succinate dehydrogenase gene (SDHD variants) are associated with an increased risk of developing paragangliomas. The aim of this study was to compare mortality rates and survival in a Dutch cohort of SDHD variant carriers with those in the general population. The study was conducted at the Leiden University Medical Center, a tertiary referral center for patients with paragangliomas. Included subjects all tested positive for SDHD variants before 1 July 2012 and visited the departments of Otorhinolaryngology or Endocrinology at least once or had a diagnosed paraganglioma and a SDHD variant-positive family history. Clinical data were retrieved from medical records, information on mortality was obtained from the Municipal Personal Records Database, and mortality rates for the Dutch population were obtained from the Dutch Central Bureau of Statistics, stratified by sex, age and date. SDHD variant carriers were followed from the date of first SDHD variant-related contact until death, emigration or 12 December 2012 and the standardized mortality ratio (SMR) was calculated. Two-hundred and seventy-five SDHD variant carriers were included in the study, of which 80% carried the c.274G>T, p.(Asp92Tyr) variant, had a mean duration of follow-up of 7.6 years, yielding 2242 person-years of observation for analysis. There were 18 deaths in the SDHD variant carrier group; two were paraganglioma related. The SMR for the whole cohort was 1.07 (95% confidence interval 0.67-1.73). In conclusion, mortality in SDHD variant carriers is not substantially increased. Additional studies are required to confirm these findings.

Abstract
Head and neck paragangliomas (HNPGLs) are rare neuroendocrine tumors belonging to the family of pheochromocytoma/paraganglioma neoplasms. Despite advances in understanding the pathogenesis of these tumors, the growth potential and clinical outcome of individual cases remains largely unpredictable. Over several decades, surgical resection has long been the treatment of choice for HNPGLs. However, increasing experience in various forms of radiosurgery has been reported to result in curative-like outcomes, even for tumors localized in the most inaccessible anatomical areas. The emergence of such new therapies challenges the traditional paradigm for the management of HNPGLs. This review will assist and guide physicians who encounter patients with such tumors, either from a diagnostic or therapeutic standpoint. This review will also particularly emphasize current and emerging knowledge in genetics, imaging, and therapeutic options as well as the health-related quality of life for patients with HNPGLs.

Abstract
PURPOSE To assess the impact of radiotherapy in paragangliomas (PGLs) with regard to overall survival, local control, volumetric response and particularly quality of life (QoL). MATERIALS AND METHODS From 1985 to 2010, 130 cases of head and neck (H&N) PGLs were managed at Bordeaux University Hospital. With a median follow-up of 7.6 years, we retrospectively present a cohort of 30 consecutive patients treated with radiation therapy for H&N PGLs. QoL was evaluated for 20 patients by the EORTC QLQ-C30 and H&N35 questionnaires through a cross-sectional study. RESULTS The 5-year overall survival and local control were 95% and 96% respectively. QoL is altered following management of PGLs. The H&N35 score is lower after combined modality therapy (surgery±embolization and radiation therapy) for speech and hearing (p=0.004), trismus (p=0.003) and total score (p=0.01) than after radiotherapy alone. Tumor shrinkage was significant at 2 and 3 years after radiotherapy (p=0.018; p=0.043). CONCLUSION Ultimate QoL should be a major goal of any treatment strategy for this benign disease. Definitive radiotherapy should be considered as a reasonable alternative to multimodality treatment as it provides comparable disease control with an apparent improvement in QoL.

Abstract
BACKGROUND Hereditary paraganglioma-pheochromocytoma syndromes (PGL/PCC) are rare tumors arising from neuroendocrine cells. METHODS AND RESULTS The proband, a 59-year-old white man and his 42-year-old elder son had a medical history of bilateral carotid body PGL and both presented for treatment of abdominal PGLs. His 36-year-old daughter had excision of recurrent malignant carotid body PGL and vertebral metastasis. His 33-year-old youngest son presented for excision of a unilateral carotid body PGL. All 4 members had succinate dehydrogenase subunit D (SDHD) mutations, whereas the proband and youngest son also had concurrent rearranged during transfection (RET) mutation. CONCLUSION This is the first report of PGL/PCC with SDHD and RET mutations. The role of the RET gene as a modifier remains speculative. Additionally, the family pedigree suggests maternal inheritance of disease from the probands' paternal grandmother. Clinicians should refer PGL/PCC families for mutation analysis as well as being alert to changes in the classification of mutations.

Abstract
CONTEXT Sinonasal paragangliomas have rarely been reported in the literature. They are often aggressive. PATIENT We report an original case of sinonasal paragangliomas with a tumor recurrence diagnosed 13 years after resection of the primary tumor. Somatostatin receptor scintigraphy and [18F]-fluorodeoxyglucose positron emission tomography/computed tomography were the most sensitive functional imaging techniques, and they ruled out distant metastases. Interestingly, [18F]-fluorodihydroxyphenylalanine positron emission tomography/computed tomography was negative, a feature that may be considered a sign of functional dedifferentiation. Screening for germline mutations of the SDHB, SDHC, SDHD, SDHAF2, VHL, MAX, and TMEM127 was negative. CONCLUSION The diagnosis of malignancy remains challenging at initial diagnosis, and patients should be followed during their entire lifetime.

Abstract
Paragangliomas (PGLs) are tumours originating from neural crest-derived cells situated in the region of the autonomic nervous system ganglia. Head-and-neck PGLs (HNPGLs) originate from the sympathetic and parasympathetic paraganglia, most frequently from the carotid bodies and jugular, tympanic and vagal paraganglia, and are usually non-catecholamine secreting. Familial PGLs are considered to be rare, but recently genetic syndromes including multiple PGLs and/or phaeochromocytomas have been more thoroughly characterised. Nowadays, genetic screening for the genes frequently implicated in both familial and sporadic cases is routinely being recommended. HNPGLs are mostly benign, generally slow-growing tumours. Continuous growth leads to the involvement of adjacent neurovascular structures with increased morbidity rates and treatment-related complications. Optimal management mostly depends on tumour location, local involvement of neurovascular structures, estimated malignancy risk, patient age and general health. Surgery is the only treatment option offering the chance of cure but with significant morbidity rates, so a more conservative approach is usually considered, especially in the more difficult cases. Radiotherapy (fractionated or stereotactic radiosurgery) leads to tumour growth arrest and symptomatic improvement in the short term in many cases, but the long-term consequences are unclear. Early detection is essential in order to increase the chance of cure with a lower morbidity rate. The constant improvement in diagnostic imaging, surgical and radiation techniques has led to a safer management of these tumours, but there are still many therapeutic challenges, and no treatment algorithm has been agreed upon until now. The management of HNPGLs requires a multidisciplinary effort addressing the genetic, surgical, radiotherapeutic, oncological, neurological and endocrinological implications. Further progress in the understanding of their pathogenesis will lead to more effective screening and earlier diagnosis, both critical to successful treatment.

Abstract
PURPOSE Malignant head and neck paragangliomas (MHNPs) are rare and occur in 6%-19% of all HNPs. We sought to identify predictors of survival and compare efficacy of treatment modalities to inform management of this rare disease. MATERIALS AND METHODS We performed a retrospective cohort study of MHNP cases in the National Cancer Institute Surveillance Epidemiology and End Results database (SEER) from 1973 to 2009. We identified 86 patients with MHNP who had documented regional or distant tumor spread with a median follow-up of 74 months. We used Cox proportional hazard models to assess the significance of demographic factors and treatment on five-year overall survival. RESULTS The most common treatment was surgery alone (36.0 %), followed by surgery with adjuvant radiation (33.7%). Five-year overall survival was 88.1% for surgery alone and 66.5% for adjuvant radiation (p = 0.2251). In univariate analysis, regional (vs. distant) spread (HR 0.23, p < 0.0001), surgery alone (HR 0.29, p < 0.0001) and primary site in the carotid body (HR 0.32, p = 0.006) conferred significant survival advantage whereas age > 50 (HR 4.04, p < 0.0001) worsened survival. Regional (vs. distant) spread (HR 0.42, p = 0.046) and age > 50 (HR 2.98, p = 0.005) remained significant in multivariate analysis. In patients with regional-only disease, five-year overall survival was 95.4% for surgery alone compared to 75.6% for surgery with radiation (p = 0.1055). CONCLUSIONS This is the largest and most contemporary series of MHNP patients. Age and tumor stage are significant factors in predicting survival. Surgical resection significantly improves survival outcomes. From this analysis, the value of adjuvant radiation is not clear.

Abstract
BACKGROUND AND OBJECTIVES Pheochromocytoma (PHEO) and paraganglioma (PGL) are rare tumors. Aims of this study were to describe and to compare demographic, clinical, pathologic, and survival characteristics of malignant PHEO and PGL. METHODS Patients were identified in SEER, 1988-2009. Analyses included chi-square, ANOVA, Kaplan-Meier, and Cox proportional hazard regression. RESULTS Gender distribution and mean age were similar for PHEO and PGL. Surgery was performed in 74.3% of PHEO and 78.9% of PGL; external beam radiation was administered in 8.0% of PHEO and 28.1% of PGL (P < 0.001). Compared to PGL, PHEO were larger (mean size 7.7 vs. 4.5 cm PGL, P = 0.001) and more were SEER-staged as localized (17.3% vs. 49.6%, respectively, P < 0.001). PGLs were more often located in the trunk than in the head/neck (53.8% vs. 38.0%, P < 0.001). PHEO had lower overall and disease-specific survival than PGL (54.0% and 73.5% vs. 73.3% and 80.5% for PGL, respectively, P < 0.001 and P = 0.118). Independent factors associated with mortality for PHEO included not undergoing surgery and metastases at diagnosis; for PGL, these were age 61-75 years, size ≥5 cm, and presenting with metastases. CONCLUSIONS Malignant PHEO has a more aggressive course than malignant PGL; long-term survival has not improved over the last two decades. Multi-institutional efforts should be pursued to seek novel treatments.

Abstract
OBJECTIVES Paragangliomas are neuroendocrine tumors derived from extra-adrenal paraganglionic cells of the autonomic nervous system. Paragangliomas of the thyroid are rare, with only 28 cases reported in the literature. The sclerosing paraganglioma variant, characterized by marked stromal sclerosis and hyalinization, has scarcely been reported. METHODS A 36-year-old woman with a history of a 1-cm vagal schwannoma followed with serial magnetic resonance imaging presented with a new solitary 2.5-cm enhancing soft tissue mass in the left thyroid. RESULTS Ultrasound examination of the thyroid revealed a hypoechoic, hypervascular, malignant-appearing mass. Two fine-needle aspirations were insufficient for diagnosis, and the mass was deemed a lesion of undetermined significance with subsequent indeterminate molecular testing. A diagnostic left thyroid lobectomy was performed, and pathologic examination revealed a lesion consistent with a sclerosing paraganglioma. CONCLUSIONS Sclerosing paragangliomas are rare tumors, and only 1 case involving a primary thyroid mass has been reported in the literature. Although the sclerosing variant has features suggestive of malignancy, the true incidence of malignancy is unknown, given the rarity of its presentation. However, given the overall benign nature of paragangliomas, the sclerosing variant is also likely benign, despite its malignant features on ultrasound and histopathologic examination.

Abstract
We conducted a retrospective study of the long-term functional results of surgery for head and neck paragangliomas. Our study population was made up of 9 patients—4 men and 5 women, aged 22 to 59 years (mean: 46.6; median: 51)—who had undergone surgical excision of a head and neck paraganglioma from January 2002 through December 2006 in the ENT Department at Pugliese-Ciaccio Hospital in Catanzaro, Italy. Of the 9 paragangliomas, 4 were carotid body tumors, 2 were glomus tympanicum tumors, and 3 were glomus vagale tumors. None of the cases was bilateral or hereditary. Complete tumor resection was achieved in 8 patients; in the remaining patient, a small amount of intradural residual vagus nerve paraganglioma had to be left in situ. The internal carotid artery was preserved in all 4 resections of carotid body tumors. There was only 1 case of postoperative lower cranial nerve deficits, which occurred in a patient with a carotid body tumor. Follow-up ranged from 12 to 53 months (mean: 37.2; median: 36), and no recurrences were documented. Our small sample showed that surgical treatment of head and neck paragangliomas provided excellent tumor control with low postoperative morbidity, even in patients with large tumors. A wait-and-scan policy may be more appropriate for patients at an advanced age or who are otherwise at high surgical risk, as well as for those whose tumors have recurred following radiotherapy.

Abstract
Similar to actors changing costumes during a performance, cancer cells undergo many rapid changes during the process of tumor metastasis, including epithelial-mesenchymal transition (EMT), acquisition of cancer stem cells (CSCs) properties, and mesenchymal-epithelial transition (MET). Such changes allow the tumor to compete with the normal microenvironment to overcome anti-tumorigenic pressures. Then, once tissue homeostasis is lost, the altered microenvironment, like that accompanying inflammation, can itself become a potent tumor promoter. This review will discuss the changes that cancer cells undergo in converting from EMT to CSCs in an inflammation microenvironment, to understand the mechanisms behind invasion and metastasis and provide insights into prevention of metastasis.

Abstract
OBJECTIVES/HYPOTHESIS To describe a novel germline mutation in the succinate dehydrogenase subunit B (SDHB) gene. STUDY DESIGN Retrospective review. METHODS The medical records of a patient with bilateral carotid body paragangliomas were reviewed. RESULTS A 35-year-old woman with a family history of neck masses presented with bilateral carotid body paragangliomas. DNA sequencing revealed a previously unreported conservative substitution (Leu111Val) mutation in the SDHB gene. CONCLUSIONS The Leu111Val germline mutation of SDHB is likely associated with a phenotype of head and neck paragangliomas, and carriers would benefit from periodic screening for sympathetic paragangliomas.
