Abstract
PET/CT imaging is a dual-modality diagnostic technology that merges metabolic and structural imaging. There are several currently available radiotracers, but 18F-FDG is the most commonly utilized due to its widespread availability. 18F-FDG PET/CT is a cornerstone of head and neck squamous cell carcinoma imaging. 68Ga-DOTA-TOC is another widely used radiotracer. It allows for whole-body imaging of cellular somatostatin receptors, commonly expressed by neuroendocrine tumors and is the standard of reference for the characterization and staging of neuroendocrine tumors. The normal biodistribution of these PET radiotracers as well as the technical aspects of image acquisition and inadequate patient preparation affect the quality of PET/CT imaging. In addition, normal variants, artifacts and incidental findings may impede accurate image interpretation and can potentially lead to misdiagnosis. In order to correctly interpret PET/CT imaging, it is necessary to have a comprehensive knowledge of the normal anatomy of the head and neck and to be cognizant of potential imaging pitfalls. The interpreter must be familiar with benign conditions which may accumulate radiotracer potentially mimicking neoplastic processes and also be aware of malignancies which can demonstrate low radiotracer uptake. Appropriate use of structural imaging with either CT, MR or ultrasound can serve a complimentary role in several head and neck pathologies including local tumor staging, detection of bone marrow involvement or perineural spread, and classification of thyroid nodules. It is important to be aware of the role of these complementary modalities to maximize diagnostic accuracy and patient outcomes. The purpose of this article is to outline the basic principles of PET/CT imaging, with a focus on 18F-FDG PET/CT and 68Ga-DOTA PET/CT. Basic physiology, variant imaging appearances and potential pitfalls of image interpretation are presented within the context of common use cases of PET technology in patients with head and neck cancers and other pathologies, benign and malignant.

Abstract
CONTEXT Pheochromocytoma and sympathetic paraganglioma (PPGL) are rare catecholamine-secreting tumors but recent studies suggest increasing incidence. Traditionally, PPGL are described to present with paroxysmal symptoms and hypertension, but existing data on clinical presentation of PPGL come from referral centers. OBJECTIVE We aimed to describe time trends in clinical presentation and incidence of PPGL in a population-based study. METHODS We conducted a nationwide retrospective cohort study of a previously validated cohort of 567 patients diagnosed with PPGL in Denmark 1977-2015. We collected clinical data from medical records of a geographic subcohort of 192 patients. We calculated age-standardized incidence rates (SIRs) and prevalence for the nationwide cohort and descriptive statistics on presentation for the subset with clinical data. RESULTS SIRs increased from 1.4 (95% CI 0.2-2.5) per million person-years in 1977 to 6.6 (95% CI 4.4-8.7) per million person-years in 2015, corresponding to a 4.8-fold increase. The increase was mainly due to incidentally found tumors that were less than 4 cm and diagnosed in patients older than 50 years with no or limited paroxysmal symptoms of catecholamine excess. On December 31, 2015, prevalence of PPGL was 64.4 (CI 95% 57.7-71.2) per million inhabitants. Of 192 patients with clinical data, 171 (89.1%) had unilateral pheochromocytoma, while unilateral paraganglioma (n = 13, 6.8%) and multifocal PPGL (n = 8, 4.2%) were rare. CONCLUSION Incidence of PPGL has increased 4.8-fold from 1977 to 2015 due to a "new" group of older patients presenting with smaller incidentally found PPGL tumors and few or no paroxysmal symptoms.

Abstract
Adrenocortical carcinoma (ACC) is a rare malignancy that arises from the adrenal cortex and often presents as adrenal incidentaloma on abdominal scans with rise in the use of imaging modalities. ACC often presents as Cushing’s syndrome or virilization. On the other hand, pheochromocytoma is an adrenal medullary tumor. It is rare for ACC to present as pheochromocytoma even though both may coexist. Moreover, ACC tumors have radiological and histological features suggestive of aggressive nature of the disease. We present a case of a 65-year-old lady who initially presented with a 3cm left adrenal incidentaloma. All of her adrenal hormones were in normal range. She was lost to follow up for several years and returned with a much enlarged lesion. Biochemical work up showed mildly increased catecholamines and metanephrines suggestive of pheochromocytoma. She didn’t have any signs or symptoms of pheochromocytoma. She was treated with alpha blockers before surgery as a prophylactic measure. Surgical pathology was consistent with the diagnosis of primary adrenal adenocarcinoma. We recommend that adrenal incidentalomas should be followed annually for up to five years as per American association of Endocrinology and the Endocrine Society guidelines to prevent morbidity and mortality in patients.

Abstract
The adrenal cortex plays pivotal roles in the maintenance of blood volume, responsiveness to stress and the development of gender characteristics. Gender differences of human adrenal cortex have been recently reported and attracted increasing interests. Gender differences occur from the developing stage of the adrenal, in which female subjects had more activated stem cells with higher renewal capacity resulting in gender-associated divergent structures and functions of cortical zonations of human adrenal. Female subjects generally have the lower blood pressure with the lower renin levels and ACE activities than male subjects. In addition, HPA axis was more activated in female than male, which could possibly contribute to gender differences in coping with various stressful events in our life. Of particular interest, estrogens were reported to suppress RAAS but activate HPA axis, whereas androgens had opposite effects. In addition, adrenocortical disorders in general occur more frequently in female with more pronounced adrenocortical hormonal abnormalities possibly due to their more activated WNT and PRK signaling pathways with more abundant activated adrenocortical stem cells present in female adrenal glands. Therefore, it has become pivotal to clarify the gender influence on both clinical and biological features of adrenocortical disorders. We herein reviewed recent advances in these fields.

Abstract
Pheochromocytoma and paraganglioma (PPGLs) are rare catecholamine-secreting neuroendocrine tumors but can be life-threatening. Although most PPGLs are benign, approximately 10% have metastatic potential. Approximately 40% cases are reported as harboring germline mutations. Therefore, timely and accurate diagnosis of PPGLs is crucial. For more than 130 years, clinical, molecular, biochemical, radiological, and pathological investigations have been rapidly advanced in the field of PPGLs. However, performing diagnostic studies to localize lesions and detect metastatic potential can be still challenging and complicated. Furthermore, great progress on genetics has shifted the paradigm of genetic testing of PPGLs. The Korean PPGL task force team consisting of the Korean Endocrine Society, the Korean Surgical Society, the Korean Society of Nuclear Medicine, the Korean Society of Pathologists, and the Korean Society of Laboratory Medicine has developed this position statement focusing on the comprehensive and updated diagnosis for PPGLs.

Abstract
Around 40% of pheochromocytomas/paragangliomas (PPGL) harbor germline mutations, representing the highest heritability among human tumors. All PPGL have metastatic potential, but metastatic PPGL is overall rare. There is no available molecular marker for the metastatic potential of these tumors, and the diagnosis of metastatic PPGL can only be established if metastases are found at "extra-chromaffin" sites. In the era of precision medicine with individually targeted therapies and advanced care of patients, the treatment options for metastatic pheochromocytoma/paraganglioma are still limited. With this review we would like to nurture the idea of the quest for non-coding ribonucleic acids as an area to be further investigated in tumor biology. Non-coding RNA molecules encompassing microRNAs, long non-coding RNAs, and circular RNAs have been implicated in the pathogenesis of various tumors, and were also proposed as valuable diagnostic, prognostic factors, and even potential treatment targets. Given the fact that the pathogenesis of tumors including pheochromocytomas/paragangliomas is linked to epigenetic dysregulation, it is reasonable to conduct studies related to their epigenetic expression profiles and in this brief review we present a synopsis of currently available findings on the relevance of these molecules in these tumors highlighting their diagnostic potential.

Abstract
Paragangliomas arise from neural cells and are found in different anatomical locations in the body. Paragangliomas in the adrenal glands are called pheochromocytoma, while the others are known as extra-adrenal paragangliomas. They are usually benign and are extremely rare in children. We present a case of a 13-year-old female patient who presented with complaints of hematuria for one year and left lower lumbar pain. Imaging investigations depicted a urinary bladder mass that was causing a mass effect at the left ureteric opening and backpressure changes in the left kidney. The patient underwent transurethral resection of bladder mass, and the histopathology confirmed the presence of paraganglioma. Though the paragangliomas of the urinary bladder are extremely rare in the pediatric age group, we suggest keeping paragangliomas on differentials when investigating a patient with bladder mass.

Abstract
Vascular endothelial growth factor (VEGF) is important in pathogenesis of different cancers. The aim of this study is to investigate the relationships between different VEGFs and clinicopathological factors in patients with phaeochromocytomas. Twenty patients (10 men; 10 women) with non-hereditary, non-metastatic phaeochromocytomas were examined for VEGF mRNA expressions by polymerase chain reaction. The expressions were correlated with the clinical and pathological factors of the patients. In addition, mouse double minute 2 (MDM2) expression in these tumours were studied by immunohistochemistry. High expressions of VEGF-A, VEGF-B, and VEGF-C mRNA were detected in 11 (55%), 9 (45%), and 9 (45%) of the tumours respectively. High expression of VEGF-A in phaeochromocytomas was significantly correlated with the tumour size (p=0.025) but did not correlate with patients' age, gender, and tumour laterality. Besides, there was a trend of VEGF-A expression correlated with MDM2 expression (p=0.064). On the other hand, expressions of VEGF-B and VEGF-C were not significantly correlated with tumour size, patients' age, gender, tumour laterality, and MDM2 expression. In addition, high expressions of VEGF-B and VEGF-A were associated with increase of tumour size (p=0.042). Co-expression of different VEGFs did not correlate with MDM2 expression. To conclude, there is a role for VEGF-A/VEGF-B/VEGF-C in the pathogenesis of non-hereditary, non-metastatic phaeochromocytomas.

Abstract
OBJECTIVES To describe a rare association of two endocrine tumours in a clinical case. CASE PRESENTATION A 54-year-old woman with a classic Papillary thyroid cancer (PTC) assessed by the Endocrinology Department of a tertiary hospital from May-2015 to May-2020. PTC was treated with a total thyroidectomy and lymphadenectomy in May-2015. Initial staging (AJCC/TNM 7th edition): T3N1bMx. Additionally, two ablative doses of 150 mCi of 131-I (RAI) were administered until September-2016. No pathological uptake was found on the post-RAI whole-body scan at any level. Due to a persistent incomplete biochemical response in February-2017, a 18Fluor-dexosiglucose positron emission computed tomography (FDG-PET) was performed. FDG-PET showed an intense pathological deposit in the right adrenal, suggestive of malignancy. Right adrenalectomy was carried out, and pathology revealed an Adrenocortical carcinoma (ACC). Genetic syndromes associated to ACC are: Li-Fraumeni syndrome (caused by an autosomal mutation in the TP53 gene), the Multiple Endocrine Neoplasia (MEN) type 1 (caused by Menin gene mutations), and MEN type 4 (caused by heterozygous mutations in the CDNK1B gene). However, none of them are associated to PTC. CONCLUSIONS To our knowledge this is the sixth published case reporting an ACC in presence of a PTC. The pathological factors behind the relation between these malignancies have not been elucidated. We do not discard the possibility of a genetic relationship between PTC and ACC.

Abstract
Recent advances in molecular genetics and genomics have led to increased understanding of the aetiopathogenesis of pheochromocytomas and paragangliomas (PPGLs). Thus, pan-genomic studies now provide a comprehensive integrated genomic analysis of PPGLs into distinct molecularly defined subtypes concordant with tumour genotypes. In addition, new embryological discoveries have refined the concept of how normal paraganglia develop, potentially establishing a developmental basis for genotype-phenotype correlations for PPGLs. The challenge for modern pathology is to translate these scientific discoveries into routine practice, which will be based largely on histopathology for the foreseeable future. Here, we review recent progress concerning the cell of origin and molecular pathogenesis of PPGLs, including pathogenetic mechanisms, genetic susceptibility and molecular classification. The current roles and tools of pathologists are considered from a histopathological perspective, including differential diagnoses, genotype-phenotype correlations and the use of immunohistochemistry in identifying hereditary predisposition and validating genetic variants of unknown significance. Current and potential molecular prognosticators are also presented with the hope that predictive molecular biomarkers will be integrated into risk stratification scoring systems to assess the metastatic potential of these intriguing neoplasms and identify potential drug targets.

Abstract
INTRODUCTION Radionuclide therapy is a promising treatment modality in metastatic pheochromocytoma/paraganglioma (PPGL). There is scarce data on 131I-metaiodobenzyl guanidine (131I-MIBG) therapy from the Indian subcontinent. Hence, we aim to study the safety and effectiveness of low-dose, low-specific activity (LSA) 131I-MIBG therapy in patients with symptomatic, metastatic PPGL. METHODS Clinical, hormonal, and radiological response parameters and side effects of LSA 131I-MIBG therapy in patients with symptomatic, metastatic PPGL were retrospectively reviewed. World health organizations' (WHO) symptomatic, hormonal, and tumor response, and response evaluation criteria in solid tumors (RECIST1.1) criteria were used to assess the response. RESULTS Seventeen (PCC: 11, sympathetic PGL: 06) patients (15 with disease progression) received low-dose LSA 131I-MIBG therapy. Complete remission (CR), partial remission (PR), stable disease (SD), and progressive disease (PD) were 18% (3/17), 24% (4/17), 18% (3/17), and 41% (7/17), respectively, for WHO symptomatic response; 20% (2/10), 10% (1/10), 30% (3/10), and 40% (4/10), respectively, for WHO hormonal response; and 19% (3/16), 6% (1/16), 31% (5/16), and 44% (7/16), respectively for tumor response based on RECIST1.1. All patients with symptomatic PD and 50% (2/4) with hormonal PD had progression as per RECIST1.1 criteria. Side effects included thrombocytopenia, acute myeloid leukemia, mucoepidermoid carcinoma, and azoospermia in 6% (1/17) each. CONCLUSIONS Our study reaffirms the modest efficacy and safety of low-dose, LSA 131I-MIBG therapy in patients with symptomatic, metastatic PPGL. Symptomatic, but not hormonal, progression after 131I-MIBG therapy correlates well with tumor progression and should be further evaluated with imaging. In resource-limited settings, anatomic imaging alone may be used to assess tumor response to 131I-MIBG therapy.

Surgical resection for liver metastasis and local recurrence of pheochromocytoma 16 years after primary surgery: A case report. Int J Surg Case Rep 2021; 81:105712. [PMID: 33684645 PMCID: PMC7941035 DOI: 10.1016/j.ijscr.2021.105712] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 02/24/2021] [Accepted: 02/25/2021] [Indexed: 12/02/2022] Open
Abstract
Pheochromocytoma is a rare tumor with malignant potential. Distant metastases are almost always unresectable, and carry a poor prognosis. Early detection and complete resection resulted in good outcomes.
Introduction and importance Pheochromocytomas arise from the adrenal medulla and are rare. Pheochromocytomas metastasize to bone, lung and liver, and surgery might be the curative treatment. However, few cases are detected when they are resectable lesions because of difficulty in diagnosis and rapid growth. We herein report a patient who underwent resection of liver metastasis and local recurrence of pheochromocytoma. Case presentation A 74-year-old woman visited our hospital for treatment for liver and retroperitoneal tumors. She had undergone left adrenal gland resection for pheochromocytoma 16 years earlier. Eleven years after primary surgery, breast cancer was diagnosed and resected. During the breast cancer follow-up, a liver tumor was identified with computed tomography. Breast cancer recurrence and metastasis were considered, so chemotherapy was administered first. However, the liver tumor gradually enlarged, and another lesion appeared in the retroperitoneum. The tumors were diagnosed as pheochromocytoma recurrence using 123I-metaiodobenzylguanidine scintigraphy, and she underwent resection of the local recurrence and liver metastasis. She was discharged on postoperative day 25 without complications, and no evidence of recurrence occurred more than 3.5 years postoperatively. Clinical discussion All pheochromocytomas have metastatic potential; however, there are no reliable markers to predict malignancy. Early detection of recurrence by regular imaging and complete resection are important in the treatment. If the recurrence was oligometastasis and tumor growth is slow, surgical resection may be eligible. Conclusion A favorable outcome resulted from complete resection for liver metastasis and local recurrence of pheochromocytoma.

Abstract
Adrenocortical carcinoma (ACC) is a heterogenous group of diseases with different clinical behaviour between adult and paediatric patients. In addition, three histological variants, oncocytic, myxoid and sarcomatoid are noted on the recent World Health Organisation (WHO) classification of ACC. A review of recent literature showed that the different types of ACC have distinctive demographic data, clinical presentation, pathology, biological behaviour, genomic and patients' prognosis. In addition, recent updates of pathology staging for ACC allow refinement of prognostic grouping for planning treatment of the patients with ACC. These advances in genomic, pathology and staging have driven the development of standardisation of pathology reporting. International standardisation of pathological reporting of adrenocortical carcinoma and adaption to local pathology communities provide universal platforms for clinicians and researchers involved in the management of patients with ACC. To conclude, all these advances in the field of pathology will improve development of management strategies including improvement of clinical care, development of prognostic markers and testing of novel therapeutic approaches for patients with adrenocortical carcinoma.

Abstract
Pediatric adrenal tumors are uncommon entities that are frequently occult and identified incidentally or by recognizing symptoms related to hormone overproduction. They often have a genetic underpinning, arise from the medulla or cortex, can be malignant or benign, and require precise diagnostic algorithms. However, pseudotumors must also be a diagnostic consideration. Therapeutic interventions and plans are tumor dependent, but surgery is a cornerstone of treatment. Ongoing surveillance after treatment, regardless of malignant determination, is of utmost importance as well.

Abstract
Paragangliomas are uncommon neuroendocrine neoplasms that occur in characteristic locations. While parasympathetic paragangliomas are mainly located at the head and neck, sympathetic paragangliomas are mostly located below the neck. Among parasympathetic paragangliomas, pheochromocytomas are the most common. Ninety percent of cases of pheochromocytomas arise within the adrenal gland. We report a case of a 63-year-old woman with an extra-adrenal pheochromocytoma of the organ of Zuckerkandl detected by CT and MRI and subsequently confirmed by postoperative histology and immunohistochemistry.

Abstract
OBJECTIVES Pediatric pheochromocytoma and paraganglioma (PPGL) are rare tumors with limited data on the diagnostic performance of 68Ga-DOTA(0)-Tyr(3)-octreotate positron emission tomography-computed tomography (68Ga-DOTATATE PET/CT). We have described our experience of 68Ga-DOTATATE PET/CT in overall and von Hippel Lindau (VHL)-associated pediatric PPGL and compared its sensitivity with that of 131I-meta-iodobenzyl-guanidine (131I-MIBG), 18F-fluorodeoxyglucose PET/CT (18F-FDG PET/CT), and contrast-enhanced CT (CECT). METHODS Retrospective evaluation of consecutive PPGL patients (age: ≤20 years), who had undergone at least one functional imaging [131I-MIBG, 18F-FDG PET/CT, and/or 68Ga-DOTATATE PET/CT], was done. Composite of anatomical and all the performed functional imaging scans, image comparator (IC), was considered as the gold standard for sensitivity analysis. RESULTS In a cohort of 32 patients (16 males, age at diagnosis: 16.4 ± 2.68 years), lesion-wise sensitivity of 68Ga-DOTATATE PET/CT (95%) was higher than that of both 18F-FDG-PET/CT (80%, p=0.027) and 131I-MIBG (65%, p=0.0004) for overall lesions, than that of 18F-FDG-PET/CT (100 vs. 67%, p=0.017) for primary PPG, and than that of 131I-MIBG (93 vs. 42%, p=0.0001) for metastases. In the VHL (n=14), subgroup, 68Ga-DOTATATE PET/CT had higher lesion-wise sensitivity (100%) compared to 18F-FDG PET/CT (74%, p=0.045) and 131I-MIBG (64%, p=0.0145). CONCLUSIONS In our pediatric PPGL cohort, overall lesion-wise sensitivity of 68Ga-DOTATATE PET/CT was higher than that of 18F-FDG PET/CT and 131I-MIBG scintigraphy. Hence, we recommend 68Ga-DOTATATE PET/CT as the preferred modality in pediatric PPGL. 68Ga-DOTATATE PET/CT may evolve as a preferred imaging modality for disease surveillance in VHL.

Abstract
Background: Recent studies have confirmed that immune-associated genes perform a crucial function in recurrence and metastasis of thyroid carcinoma. A reliable immune-related prognostic signature for patients with thyroid cancer is needed. This study constructed a novel immune-related prognostic signature for thyroid cancer and evaluated its prognostic value by bioinformatics analysis. Methods: In this study, we anatomized differentially expressed immune-associated genes from The Cancer Genome Atlas database. The samples from The Cancer Genome Atlas database were randomly divided into training set and test set. A novel immune-related prognostic signature for thyroid cancer was developed by least absolute shrinkage and selection operator and Cox regression analysis: Risk score = (0.6846 × expression value of C-X-C motif chemokine ligand 5 [CXCL5]) + (1.1556 × expression value of Azurocidin 1 [AZU1]) + (−0.3156 × expression value of nucleotide binding oligomerization domain containing 1 [NOD1] + (0.0542 × expression value of TNF Receptor Superfamily Member 11b [TNFRSF11B]) + (0.0952 × expression value of VGF nerve growth factor inducible [VGF]). The established prognostic signature was evaluated based on training set and test set by survival curves, receiver–operator characteristic curves, risk score, survival status, heatmap, and independent prognostic analysis. Meanwhile, we appraised the correlation between target immune-associated genes and clinical stage, tumor-infiltrating immune cells respectively. Results: Five immune-associated genes were used for constructing an immune-related prognostic signature by least absolute shrinkage and selection operator, univariate, and multivariate analysis. Survival curves, receiver–operator characteristic curves, and independent prognostic analysis showed the signature had significant prediction value. Clinical and immune cell correlation analyses indicated that target immune-associated genes may participate in tumor immune infiltration and tumor progression. Conclusions: We constructed a novel 5 immune-associated genes signature for predicting the prognosis of patients with thyroid cancer, which may help clinical workers evaluate individualized therapy and prognosis.

Abstract
Purpose: Pheochromocytoma and paraganglioma (PGL), together called PPGL, are rare tumors with a limited number of studies on the diagnostic performance of 68Ga-DOTA (0)-Tyr (3)-octreotate positron emission tomography-computed tomography (68Ga-DOTATATE PET/CT) from the Asian-Indian subcontinent. Materials and Methods: In this retrospective study, PPGL suspects (n = 87) who had undergone at least contrast-enhanced computed tomography (CECT) and 68Ga-DOTATATE PET/CT, were included. Lesion-wise, patient-wise, and region-wise sensitivities of 68Ga-DOTATATE PET/CT, 18F fluorodeoxyglucose positron emission tomography CT (18F-FDG PET/CT, n = 53), 131I-metaiodobenzylguanidine (131I-MIBG, n = 37), and CECT were compared, and diagnostic performance of 68Ga-DOTATATE PET/CT in the detection of PPGL was calculated. Results: 68Ga-DOTATATE PET/CT had significantly higher lesion-wise sensitivity than 131I-MIBG for both primary (94% vs 75%, P = 0.004) and metastatic disease (85% vs 59%, P = 0.001) and higher sensitivity than CECT for metastatic lesions (83% vs 43%, P = 0.0001). The lesion-wise sensitivity of 68Ga-DOTATATE PET/CT was similar to 18F-FDG PET/CT for both primary tumors (94% vs 85%, P = 0.08) and metastatic lesions (82% vs 84%, P = 0.76) in the whole cohort but tended to be inferior in the head to head comparison. Conclusion: 68Ga-DOTATATE PET/CT had higher sensitivity for detection of PPGL than 131I-MIBG (primary and metastatic) and CECT (metastatic) but similar to 18F-FDG PET/CT (primary and metastatic).

Abstract
BACKGROUND Metastatic pheochromocytomas and paragangliomas (PPGLs) occur in about 5-26% of cases and are characterized by a heterogeneous prognosis. Metastases can be synchronous at the initial diagnosis, but they can occur also many years after surgery for the primary tumor. To date, the treatment of patients affected by metastatic PPGLs represents a clinical challenge because of the lack of guidelines. AIM The aim of this article is to review the available management options and their impact on the outcomes of patients with metastatic PPGLs. RESULTS Generally, treatments are not curative. Surgery, when possible, can be used to reduce hormonal symptoms and cardiovascular morbidity. Chemotherapy plays a role in patients with high burden tumor and rapid disease progression. Tyrosine kinases inhibitors (TKIs) might be considered for their ability to block the angiogenesis and cell growth. Radiation therapy and interventional radiology techniques can help in the management of local metastases to control symptoms and avoid tumor progression. On the other hand, peptide receptor radionuclide therapy (PRRT), using 90Y or 177Lu-DOTATATE, could be a promising therapy. In addition, high specific 131I-MIBG was approved by the Food and Drug Administration (FDA) in the US for the treatment of patients affected by metastatic and unresectable 131I-MIBG positive PPGLs. Considering the different pathways involved in the pathogenesis of PPGLs, several target therapies have been proposed and are under evaluation in clinical trials. CONCLUSIONS The choice of the appropriate treatment should be based on multidisciplinary and personalized approach taking into account the rarity and the variability of these tumors.

Abstract
PURPOSE This work aimed to evaluate genotype-phenotype associations in individuals carrying germline variants of transmembrane protein 127 gene (TMEM127), a poorly known gene that confers susceptibility to pheochromocytoma (PHEO) and paraganglioma (PGL). DESIGN Data were collected from a registry of probands with TMEM127 variants, published reports, and public databases. MAIN OUTCOME ANALYSIS Clinical, genetic, and functional associations were determined. RESULTS The cohort comprised 110 index patients (111 variants) with a mean age of 45 years (range, 21-84 years). Females were predominant (76 vs 34, P < .001). Most patients had PHEO (n = 94; 85.5%), although PGL (n = 10; 9%) and renal cell carcinoma (RCC, n = 6; 5.4%) were also detected, either alone or in combination with PHEO. One-third of the cases had multiple tumors, and known family history was reported in 15.4%. Metastatic PHEO/PGL was rare (2.8%). Epinephrine alone, or combined with norepinephrine, accounted for 82% of the catecholamine profiles of PHEO/PGLs. Most variants (n = 63) occurred only once and 13 were recurrent (2-12 times). Although nontruncating variants were less frequent than truncating changes overall, they were predominant in non-PHEO clinical presentations (36% PHEO-only vs 69% other, P < .001) and clustered disproportionately within transmembrane regions (P < .01), underscoring the relevance of these domains for TMEM127 function. Integration of clinical and previous experimental data supported classification of variants into 4 groups based on mutation type, localization, and predicted disruption. CONCLUSIONS Patients with TMEM127 variants often resemble sporadic nonmetastatic PHEOs. PGL and RCC may also co-occur, although their causal link requires further evaluation. We propose a new classification to predict variant pathogenicity and assist with carrier surveillance.

Abstract
PURPOSE OF REVIEW Pheochromocytomas and paragangliomas (PPGL) display a strong genetic determinism with 40% of inherited forms. The purpose of this review is to provide an update on current knowledge on adult forms of hereditary PPGL and their management. RECENT FINDINGS PPGL are genetically-driven in 70% of cases, with germline and/or somatic mutations identified in more than 20 genes. Although eight new susceptibility genes have recently emerged, mutations on SDHx genes remain the most frequent. In addition to SDHB, mutations in SLC25A11, FH and MDH2 may predispose to a metastatic disease and somatic alterations including TERT and ATRX mutations, and the differential expression on noncoding RNAs are also associated with the occurrence of metastases.The biochemical diagnosis remains the mainstay of functional PPGL and does not differ between hereditary PPGL while the choice of the best nuclear imaging approach is dictated by the tumor type and can be influenced by the presence of a germline mutation (18F-DOPA PET/CT for cluster 2 mutation and Ga-DOTATATE PET/CT for cluster 1 mutation). SUMMARY A systematic genetic testing and counselling is recommended for all PPGL patients and should lead to conservative surgery and an adapted follow up, in case of hereditary form.

Prognostic Nomograms for Predicting Overall Survival and Cancer-Specific Survival of Patients With Malignant Pheochromocytoma and Paraganglioma. Front Endocrinol (Lausanne) 2021; 12:684668. [PMID: 34234744 PMCID: PMC8257089 DOI: 10.3389/fendo.2021.684668] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Accepted: 06/04/2021] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Malignant pheochromocytoma and paraganglioma (PPGL) are rare tumors with few prognostic tools. This study aimed to construct nomograms for predicting 3- and 5-year survival for patients with malignant PPGL. METHODS The patient data was retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. A total of 764 patients diagnosed with malignant PPGL from 1975 to 2016 were included in this study. The patients were randomly divided into two cohorts; the training cohort (n = 536) and the validation cohort (n = 228). Univariate analysis, Lasso regression, and multivariate Cox analysis were used to identify independent prognostic factors, which were then utilized to construct survival nomograms. The nomograms were used to predict 3- and 5-year overall survival (OS) and cancer-specific survival (CSS) for patients with malignant PPGL. The prediction accuracy of the nomogram was assessed using the concordance index (C-index), receiver operating characteristic (ROC) curves and calibration curves. Decision curve analysis (DCAs) was used to evaluate the performance of survival models. RESULTS Age, gender, tumor type, tumor stage, or surgery were independent prognostic factors for OS in patients with malignant PPGL, while age, tumor stage, or surgery were independent prognostic factors for CSS (P <.05). Based on these factors, we successfully constructed the OS and CSS nomograms. The C-indexes were 0.747 and 0.742 for the OS and CSS nomograms, respectively. In addition, both the calibration curves and ROC curves for the model exhibited reliable performance. CONCLUSION We successfully constructed nomograms for predicting the OS and CSS of patients with malignant PPGL. The nomograms could inform personalized clinical management of the patients.

Abstract
PURPOSE OF REVIEW Pheochromocytomas and paragangliomas are rare tumors arising, respectively, from the adrenal medulla and extra-adrenal sympathetic or parasympathetic paraganglia. The main therapeutic objectives in case of metastatic disease are the reduction of tumor burden and the control of symptoms resulting from excessive catecholamine secretion. Treatment choices constitute not only a wait and see attitude, locoregional approaches, chemotherapy regiments but also radiopharmaceutical agents, and they should be discussed in a specialized multidisciplinary board. This review will briefly discuss the radiopharmaceutical modalities in patients with pheochromocytomas and paragangliomas (I-MIBG and PRRT). RECENT FINDINGS I-MIBG (Azedra) has received FDA approval for patients with iobenguane-scan-positive, unresectable, locally advanced or metastatic pheochromocytomas and paragangliomas who require systemic anticancer therapy, whereas peptide receptor radionuclide therapy using radiolabelled somatostatin analogues is currently performed in compassionate use, with very promising results. No prospective head-to-head comparison between the modalities has been conducted to date. SUMMARY Promising results have been reported for both radiopharmaceutical agents, mostly in the setting of retrospective series. No prospective head-to-head comparison between the modalities is yet available.

Abstract
BACKGROUND Ganglioneuromas are very rare tumours of the sympathetic nervous system. Clinical and pathological knowledge is currently based on largely incomparable registries and case series that focus on paediatric or adrenal cases. To comprehensively characterize the full clinical spectrum across ages and locations, a meta-analysis was performed where amenable and complemented by systematic literature review of individual patient data (IPD). DESIGN Articles containing "ganglioneuroma" in English on humans, published from 1/1/1995-6/27/2018, were identified from PubMed. Aggregate data from 10 eligible patient series on 19 variables were considerably inhomogeneous, restricting meta-analysis to age and gender distribution. To determine basic disease characteristics across ages and locations, IPD were retrieved from case reports and small case series (PROSPERO CRD42018010247). RESULTS Individual patient data representing 364 cases revealed that 65.7% (60.6%-70.4%) were diagnosed in adults, more frequently in females (62%, 56.9%-66.9%). 24.5% (20.3%-39.1%) were discovered incidentally. Most often, ganglioneuromas developed in abdomen/pelvis (66.2, 32.1% adrenal). With age, the proportion of ganglioneuroma localizations with high post-surgical complication rate (35.6% head/neck and 16.3% thorax) decreased. Contrarily, the diagnosis of adrenal ganglioneuromas (<1% post-surgical complications) increased with age. Hormone production, hypertension or coincidence with another non-neuroblastic neural-crest-derived tumour component was more common for adrenal location. Recurrence and metastatic spread have not been reported for ganglioneuromas without secondary tumour component. CONCLUSIONS This work summarizes characteristics of the currently largest number of international GN patients across all ages. The data confirm a benign nature of GN, independent of age. Age-related differences in predominant tumour location, associated post-surgical complications and hormone production suggest case-centred management strategies.

Abstract
Due to its rarity, adrenal hemorrhage is difficult to diagnose, and its precise etiology has remained unknown. One of the pivotal mechanisms of adrenal hemorrhage is the thrombosis of the adrenal vein, which could be due to thrombophilia. However, detailed pathological evaluation of resected adrenal glands is usually required for definitive diagnosis. Here, we report a case of a cortisol-secreting adenoma with concomitant foci of hemorrhage due to antiphospholipid syndrome diagnosed both clinically and pathologically. In addition, the tumor in this case was pathologically diagnosed as cortisol-secreting adenoma, although the patient did not necessarily fulfill the clinical diagnostic criteria of full-blown Cushing or sub-clinical Cushing syndrome during the clinical course, which also did highlight the importance of detailed histopathological investigations of resected adrenocortical lesions.

Abstract
CONTEXT Until recently, there are few effective treatment options for patients with synchronous metastatic phaeochromocytoma (PHEO) and paraganglioma (PGL). Surgical resection may improve the survival outcomes of these patients. OBJECTIVE To assess the role of surgical resection of the primary tumour in patients with synchronous metastatic PHEO and PGL. DESIGN Retrospective analysis of patients with synchronous metastatic PHEO/PGL using the Surveillance, Epidemiology, and End Results database (1988-2016). PATIENTS Patients with synchronous metastatic PHEO/PGL who underwent primary tumour resection. MEASUREMENTS Overall survival and Cox regression analyses. RESULTS A total of 99 patients with metastatic PHEO and 127 metastatic PGL patients were identified from the SEER database. Compared to metastatic PHEO, metastatic PGL patients had a better overall survival (5-year survival rate: 33.3% vs. 49.0%, p = .001). In metastatic PHEO patients, 53 (53.5%) patients underwent surgery for primary site. Surgically treated patients had an improved survival compared to non-surgery patients (5-year survival rate: 50.9% vs. 29.6%, p = .017). Among metastatic PGL patients, primary tumour resection was performed in 74 (58.3%) patients and had no significant effect on the survival of metastatic PGL. In sub-analyses, surgery only conferred a survival benefit in patients with primary tumours originated from aortic/carotid bodies, rather than other sites or abdominal tumours. CONCLUSION Our findings suggest that primary tumour resection is associated with improved survival in patients with synchronous metastatic PHEO and those with PGL diseases located in aortic/carotid bodies. In addition, PHEO and PGL should be treated as two distinct clinical entities.

Abstract
BACKGROUND Hereditary paraganglioma (PGL) and pheochromocytoma (PCC) syndromes are rare conditions, with limited data on spectrum of causative gene variants of these syndromes in Asian patients. METHODS We describe the clinical characteristics and genetic testing outcomes of patients with suspected hereditary PGL/PCC who were referred to a tertiary cancer genetics clinic in Singapore. RESULTS Among 2196 patients with suspected hereditary cancer syndrome evaluated at the cancer genetics clinic from 2000 to 2019, 13/2196 (0.6%) patients fulfilled clinical suspicion for hereditary PGL/PCC syndrome. After genetic counselling, 10 patients underwent multi-gene next generation sequencing and deletion/duplication analysis, including SDHAF2, SDHA, SDHB, SDHC, SDHD, VHL, NF1, RET, MAX, and TMEM127. Seven of 10 patients (70%) were identified to carry pathogenic variants, including 3 unrelated Chinese patients with head and neck PGL who carried the same SDHD: c.3G > C (p.Met1Ile) variant that was previously reported to be a possible founder variant in Chinese, and 3 patients with urogenital PGL and 1 patient with retroperitoneal PGL who carried different SDHB variants. Variant carriers were younger, more likely to present with multiple tumours, or have family history of paraganglioma or pheochromocytoma, than non- variant carriers. CONCLUSION Hereditary PGL/PCC accounts for only 0.6% of patients seen in an adult cancer genetics clinic in Asia. SDHD and SDHB genes remain the most important causative genes of hereditary PGL/PCC in Asia even when patients are tested with multi-gene NGS panel.

Abstract
Pheochromocytomas (PCC) and paragangliomas (PGL) are rare neuroendocrine tumors arising from chromaffin cells in the adrenal medulla, sympathetic or parasympathetic ganglia. Currently, the only curative treatment option of pheochromocytomas/paraganglioma (PPGL) is surgical resection. Surgery aims to eliminate both risks of hypersecretion and tumor growth. The consequences of hypersecretion should be carefully controlled with medical therapy before and during the surgery. Postoperative major complications are hypotension and rebound hypoglycemia, and patients should be followed closely for 24-48 hours. The choice of surgical approach is determined based on multiple factors, including germline genetic test results, the size of the tumor, body mass index, surgeon's experience, and the likelihood of malignancy. Primary tumor resection does not completely eliminate the risk of tumor persistence and recurrence. Therefore, all patients with PPGL who are surgically treated should be followed for at least 10 years for recurrent disease and new tumor formation. Although surgical resection is the only curative treatment for PPGLs, surgical treatment is palliative except for resectable locoregional metastases in metastatic disease or for isolated distant metastases. The purpose of palliative treatment is to reduce hormone secretion and prevent metastasis-related complications in a critical anatomical location Combined and alfa;- and beta- adrenergic blockade is usually applied in patients with PPGL preoperatively. Some patients may present with pheochromocytoma multisystem crisis, which is a life-threatening condition that can involve cardiovascular, pulmonary, neurological, gastrointestinal, renal, hepatic and metabolic systems. Pheochromocytoma crisis may be spontaneous or may present with the tumor manipulation, trauma, corticosteroids, beta-blockers, anesthetic drugs, and the stimulation of non-adrenal surgical stress. These patients should be considered as medical emergencies rather than surgical emergencies. In this review, it was aimed to evaluate the pre-, per and post-operative management, curative and palliative surgical management, and postoperative outcomes and follow-up of the patients with PPGLs.

Abstract
BACKGROUND Pheochromocytoma and paragangliomas (PPGL) are hereditary in approximately 30% to 40% cases. With the advancement of genetic analysis techniques, including next-generation sequencing (NGS), there were attempts to classify PPGL into molecular clusters. With NGS being applied to clinical settings recently, we aimed to review the results of genetic analysis, including NGS, and investigate the association with clinical characteristics in Korean PPGL patients. METHODS We reviewed the medical records of PPGL patients who visited Severance hospital from 2006 to 2019. We documented the clinical phenotype of those who underwent targeted NGS or had known germline mutations of related genes. RESULTS Among 57 PPGL patients, we found 28 pathogenic germline mutations of susceptibility genes. Before the targeted NGS was implemented, only obvious syndromic feature lead to the Sanger sequencing for the specific genes. Therefore, for the exact prevalence, only patients after the year 2017, when targeted NGS was added, were included (n=43). The positive germline mutations were found in 14 patients; thus, the incidence rate is 32.6%. Patients with germline mutations had a higher likelihood of family history. There were significant differences in the type of PPGLs, percentage of family history, metastasis rate, presence of other tumors, and biochemical profile among three molecular clusters: pseudohypoxic tricarboxylic acid cycle-related, pseudohypoxic von Hippel-Lindau (VHL)/endothelial PAS domain-containing protein 1-related, and kinase-signaling group. Germline mutations were identified in seven PPGL-related genes (SDHB, RET, VHL, NF1, MAX, SDHA, and SDHD). CONCLUSION We report the expected prevalence of germline mutations in Korean PPGL patients. NGS is a useful and accessible tool for genetic analysis in patients with PPGLs, and further research on molecular classification is needed for precise management.

Abstract
Pheochromocytomas/paragangliomas (PPGLs) are rare neuroendocrine tumours linked to more than 15 susceptibility genes. PPGLs present with very different genotype/phenotype correlations. Certainly, depending on the mutated gene, and the activated intracellular signalling pathways, as well as their metastatic potential, each tumour is immensely different. One of the major challenges in in vitro research, whatever the study field, is to choose the best cellular model for that study. Unfortunately, most of the time there is not 'a best' cell model. Thus, in order to avoid observations that could be related to and/or dependent on a specific cell line, researchers often perform the same experiments using different cell lines simultaneously. The situation is even more complicated when there are only very few cell models obtained in different species for a disease. This is the case for PPGLs. In this review, we will describe the characteristics of the different cell lines and of mouse models, trying to understand if there is one that is more appropriate to use, depending on which aspect of the tumours one is trying to investigate.

Abstract
Background Paragangliomas (PGLs) are extremely rare neuroendocrine tumours arising from extra-adrenal chromaffin cells. PGLs are clinically rare, difficult to diagnose and usually require surgical intervention. PGLs mostly present catecholamine-related symptoms. We report a case of Acute abdomen as the initial manifestation of haemorrhagic retroperitoneal PGL. There has been only one similar case reported in literature. Case presentation We present a unique case of a 52-year-old female with acute abdomen induced by haemorrhagic retroperitoneal PGL. The patient had a 5-h history of sudden onset of serve right lower quadrant abdominal pain radiating to the right flank and right lumbar region. Patient had classic symptoms of acute abdomen. Abdominal ultrasound revealed a large abdominal mass with a clear boundary. A Computed Tomography Angiography (CTA) of superior mesenteric artery was also performed to in the emergency department. The CTA demonstrated a large retroperitoneal mass measured 9.0 × 7.3 cm with higher density inside. A provisional diagnosis of retroperitoneal tumour with haemorrhage was made. The patient received intravenous fluids, broad-spectrum antibiotics and somatostatin. On the 3rd day of admission, her abdominal pain was slightly relieved, but haemoglobin decreased from 10.9 to 9.4 g/dL in 12 h suggesting that there might be active bleeding in the abdominal cavity. Thus, we performed a midline laparotomy for the patient. Haemorrhage was successfully stopped during operation. The retroperitoneal tumour with haemorrhage was completely removed. The abdominal pain was significantly relieved after surgery. The patient initially presented with acute abdomen instead of catecholamine-related symptoms. The diagnosis of retroperitoneal PGL with haemorrhage was finally confirmed by postoperative pathological and immunohistochemical results. The postoperative course was uneventful. At the 1-year follow-up visit, no tumour recurrence was observed by Single Photon Emission Computed Tomography. A literature review was performed to further understand and analyse the aforementioned disease. Conclusion Acute abdomen as the initial manifestation of haemorrhagic retroperitoneal paraganglioma is extremely rare. Abdominal Computed Tomography is essential to locate the lesion and differentiate between other causes of acute abdomen. PGLs are hypervascular tumours. We should be aware that ruptured retroperitoneal PGL with massive bleeding could be life threatening and require emergency laparotomy.

Abstract
Cholesterol is essential for a variety of functions in endocrine-related cells, including hormone and steroid production. We have reviewed the progress to date in research on the role of the main cholesterol-containing lipoproteins; low-density lipoprotein (LDL) and high-density lipoprotein (HDL), and their impact on intracellular cholesterol homeostasis and carcinogenic pathways in endocrine-related cancers. Neither LDL-cholesterol (LDL-C) nor HDL-cholesterol (HDL-C) was consistently associated with endocrine-related cancer risk. However, preclinical studies showed that LDL receptor plays a critical role in endocrine-related tumor cells, mainly by enhancing circulating LDL-C uptake and modulating tumorigenic signaling pathways. Although scavenger receptor type BI-mediated uptake of HDL could enhance cell proliferation in breast, prostate, and ovarian cancer, these effects may be counteracted by the antioxidant and anti-inflammatory properties of HDL. Moreover, 27-hydroxycholesterol a metabolite of cholesterol promotes tumorigenic processes in breast and epithelial thyroid cancer. Furthermore, statins have been reported to reduce the incidence of breast, prostate, pancreatic, and ovarian cancer in large clinical trials, in part because of their ability to lower cholesterol synthesis. Overall, cholesterol homeostasis deregulation in endocrine-related cancers offers new therapeutic opportunities, but more mechanistic studies are needed to translate the preclinical findings into clinical therapies.

Abstract
Objective To investigate the computed tomography (CT) characteristics of adrenal ganglioneuromas (AGNs) and to determine the ability of CT scanning to distinguish between large (>3 cm) and small (≤3 cm) AGNs. Methods This retrospective study searched the electronic medical record system of a hospital between January 2008 and July 2019 in order to identify patients with pathologically-confirmed AGNs that underwent three phases of CT scanning. The CT features were compared between large and small AGNs. Results A total of 30 patients with pathologically-confirmed AGNs were included in the study. The majority of patients (76.7%; 23 of 30) were asymptomatic and there were nonspecific symptoms in seven patients. The ‘pointed peach’ sign appeared in more than half of the patients (53.3%; 16 of 30). The CT value of the arterial phase, progressive enhancement, morphology and calcification in the CT images were found to be significantly different between large and small AGNs. Progressive enhancement was more likely to occur in small AGNs. Most large AGNs had irregular shapes, while small AGNs were likely to be round or oval with a smooth border. Calcifications were noted in large AGNs (42.9%; six of 14). Conclusion CT scanning can show many of the key imaging characteristics of AGNs used to distinguish between large and small AGNs.

Abstract
We present the case of a 26-year-old woman living at a high altitude diagnosed initially with nonfamilial and nonsecretory localized carotid body tumor managed with surgery, which developed into a recurrent metastatic tumor treated with cyclophosphamide, vincristine, and dacarbazine. The patient continued to progress and developed a left carotid artery thrombosis and worsening of her systemic symptoms. The patient was re-evaluated, and she decided on no further surgery or systemic therapy. DOTATATE positron emission tomography/computed tomography showed widespread somatostatin-avid disease involving the left carotid bulb mass, bilateral lung nodules, and liver metastases, with the largest in the right hepatic lobe measuring 8 × 7 cm. There were peripancreatic lymph nodes and scattered skeletal metastases. The patient sought a second opinion, on the basis of which she was prescribed pazopanib, to which she showed a dramatic clinical response after 1 month, followed by a durable response for 1 year. Tyrosine kinase inhibitors such as pazopanib are potentially useful in paraganglioma, with further studies needed to understand the role of vascular endothelial growth factor receptor-directed kinase inhibitors in this setting.

Abstract
Cortisol-producing adrenocortical adenomas (CPAs) are associated with ACTH-independent Cushing's syndrome and histologically composed of two cellular subtypes: compact (lipid-poor) and clear (lipid-rich) tumor cells. However, the details of hormonal and biological activities of these tumor cells have remained unknown, especially in CPAs. CPAs frequently harbored unique histological features different from those of aldosterone-producing adenomas (APAs) including a senescent phenotype. Therefore, we explored the association between morphological features and the immunoreactivity of steroidogenic enzymes in CPAs with different genotypes and compared them with cellular senescence markers as well as clinicopathological factors of the cases. Hormonal activities (3βHSD, CYP21A, CYP17A1, CYP11B1 and DHEA-ST) and cellular senescence markers (p16, p21 and Ki-67) within different morphological features (clear and compact) were evaluated in 40 CPAs. CPA genotypes (PRKACA, GNAS and CTNNB1) were examined by Sanger sequencing and then compared them with the factors above. p21 immunoreactivity was significantly positively correlated with that of CYP21A (p = 0.0110), CYP17A1 (p = 0.0356) and DHEA-ST (p = 0.0420) but inversely with tumor size (p = 0.0015). CYP21A (p = 0.0016), CYP11B1 (p = 0.0001), CYP17A1 (p < 0.0001) and p16 (p = 0.0137) immunoreactivity were all significantly higher in compact cells than those in clear cells. CYP17A1 (p = 0.0056) and 3βHSD (p = 0.0437) immunoreactivity was significantly higher in PRKACA-mutated than wild type CPAs. p16 immunoreactivity and serum DHEA-S level were both significantly higher in GNAS-mutated than PRKACA-mutated (p = 0.0250) and wild type (p = 0.0180) CPAs. Results of our present study did demonstrate that compact tumor cells were hormonally active and more senescent than clear tumor cells in CPAs. PRKACA- and GNAS-mutated tumor cells were more hormonally active and senescent than those without mutations despite the similar morphological features. We herein proposed a novel histological classification of the tumor cell subtypes based on in situ cortisol excess, genotypes and the status of cell senescence in CPAs.

Abstract
Anaplastic thyroid cancer (ATC) remains as one of the most aggressive human carcinomas with poor survival rates in patients with the cancer despite therapeutic interventions. Novel targeted and personalized therapies could solve the puzzle of poor survival rates of patients with ATC. In this review, we discuss the role of non-coding RNAs in the regulation of gene expression in ATC as well as how the changes in their expression could potentially reshape the characteristics of ATCs. A broad range of miRNA, such as miR-205, miR-19a, miR-17-3p and miR-17-5p, miR-618, miR-20a, miR-155, etc., have abnormal expressions in ATC tissues and cells when compared to those of non-neoplastic thyroid tissues and cells. Moreover, lncRNAs, such as H19, Human leukocyte antigen (HLA) complex P5 (HCP5), Urothelial carcinoma-associated 1 (UCA1), Nuclear paraspeckle assembly transcript 1 (NEAT1), etc., participate in transcription and post-transcriptional regulation of gene expression in ATC cells. Dysregulations of these non-coding RNAs were associated with development and progression of ATC by modulating the functions of oncogenes during tumour progression. Thus, restoration of the abnormal expression of these miRNAs and lncRNAs may serve as promising ways to treat the patients with ATC. In addition, siRNA mediated inhibition of several oncogenes may act as a potential option against ATC. Thus, non-coding RNAs can be useful as prognostic biomarkers and potential therapeutic targets for the better management of patients with ATC.

Abstract
Endothelial PAS domain-containing protein 1 (EPAS1) is an oxygen-sensitive component of the hypoxia-inducible factors (HIFs) having reported implications in many cancers by inducing a pseudo-hypoxic microenvironment. However, the molecular dysregulation and clinical significance of EPAS1 has never been investigated in depth in phaeochromocytomas/paragangliomas. This study aims to identify EPAS1 mutations and alterations in DNA copy number, mRNA and protein expression in patients with phaeochromocytomas/paragangliomas. The association of molecular dysregulations of EPAS1 with clinicopathological factors in phaeochromocytomas and paragangliomas were also analysed. High-resolution melt-curve analysis followed by Sanger sequencing was used to detect mutations in EPAS1. EPAS1 DNA number changes and mRNA expressions were examined by polymerase chain reaction (PCR). Immunofluorescence assay was used to study EPAS1 protein expression. In phaeochromocytomas, 12% (n = 7/57) of patients had mutations in the EPAS1 sequence, which includes two novel mutations (c.1091A>T; p.Lys364Met and c.1129A>T; p.Ser377Cys). Contrastingly, in paragangliomas, 7% (n = 1/14) of patients had EPAS1 mutations and only the c.1091A>T; p.Lys364Met mutation was detected. In silico analysis revealed that the p.Lys364Met mutation has pathological potential based on the functionality of the protein, whereas the p.Ser377Cys mutation was predicted to be neutral or tolerated. The majority of the patients had EPAS1 DNA amplification (79%; n = 56/71) and 53% (n = 24/45) patients shown mRNA overexpression. Most of the patients with EPAS1 mutations exhibited aberrant DNA changes, mRNA and protein overexpression. In addition, these alterations of EPAS1 were associated with tumour weight and location. Thus, the molecular dysregulation of EPAS1 could play crucial roles in the pathogenesis of phaeochromocytomas and paragangliomas.

Abstract
PURPOSE OF REVIEW Although the majority of pheochromocytoma and paraganglioma are benign, 15-17% develop metastatic disease, being present at the initial diagnosis in about 11-31% of cases. The natural course of metastasized disease is highly heterogeneous, with an overall 5-year survival rate varying between 40% and 85%. For individual patients, overall survival, progression-free survival, and clinical outcome are difficult to predict. Management of metastasized pheochromocytoma and paraganglioma is challenging. Currently available therapeutic options are surgical debulking, treatment with radiopharmaceuticals (I-MIBG, Y and Lu-DOTATATE), chemotherapy and targeted therapy. RECENT FINDINGS The pathogenesis of pheochromocytoma and paraganglioma (PPGL) is largely driven by genomic alterations in PPGL susceptibility genes related to three different clusters: altered pseudo-hypoxic signaling (cluster-1), altered MAP-kinase signaling (cluster-2) and altered Wnt signaling (cluster-3). Novel targeted therapies (tyrosine kinase inhibitors) and potential future therapeutic options, guided by improved knowledge about the oncogenic cluster 1-3 signaling pathways, will be discussed. SUMMARY Treatment of metastasized pheochromocytoma and paraganglioma remains challenging. Profiling of gene expression and methylation can serve as a powerful tool for characterizing disease clusters and for guiding targeted therapy to improve selectivity and efficacy. Current knowledge of signatures involved in molecular signaling, metabolism, and resistance mechanisms of PPGLs suggests that therapeutic regimens can be optimized to each molecular subtype.

Abstract
A 68-year-old woman presented with episodes of headache, palpitations, sweating and poorly controlled hypertension for the past 6 years. These symptoms were, at times, associated with micturition, and there were few episodes of micturition syncope as well. She had elevated 24-hour urinary normetanephrine and was found to have a paraganglioma arising from the urinary bladder infiltrating the sigmoid colon. She underwent laparotomy with excision of the bladder paraganglioma, following which her symptoms subsided. Paragangliomas are extra-adrenal catecholamine-producing tumours. Bladder paragangliomas need to be considered when evaluating hypertensive patients with headache, palpitations or syncope related to micturition.

Abstract
Adrenocortical carcinoma (ACC) is a rare malignant tumor arising from the adrenal cortex and it is even rarer in infancy. These tumors are usually hormonally active. We report a case of ACC in a 6-month-old infant who was brought by her mother with complaints of hirsutism and abnormally looking genitalia. Serum 17-alpha-hydroxyprogesterone and serum cortisol levels were raised. Subsequently, imaging studies revealed a large well-circumscribed soft-tissue mass in the right suprarenal region. The tumor was excised, and on histopathology in conjunction with immunohistochemistry, a diagnosis of ACC was given. Only four other cases of ACC have been reported till date in the literature, with an age of 6 months or younger. Hereby, we present a case of ACC in a young infant.

Phase II Clinical Trial of Pembrolizumab in Patients with Progressive Metastatic Pheochromocytomas and Paragangliomas. Cancers (Basel) 2020; 12:cancers12082307. [PMID: 32824391 PMCID: PMC7465458 DOI: 10.3390/cancers12082307] [Citation(s) in RCA: 41] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 08/07/2020] [Accepted: 08/14/2020] [Indexed: 02/06/2023] Open
Abstract
Metastatic pheochromocytomas and paragangliomas (MPPGs) are rare endocrine malignancies that are associated with high rates of morbidity and mortality because of their large tumor burden and location, progression, and release of catecholamines. Systemic therapies for MPPGs are limited. MPPGs are characterized by pseudohypoxia that may prevent immune system recognition. We conducted a phase II clinical trial of pembrolizumab in patients with progressive MPPGs. The primary endpoint was the non-progression rate at 27 weeks. The secondary endpoints included the objective response and clinical benefit rates, progression free and overall survival duration, and safety. We also determined whether PDL-1 expression and the presence of infiltrating mononuclear inflammatory cells in the primary tumor were associated with clinical response and hereditary background. Eleven patients were included in this trial, four (36%) with germline mutations and seven (64%) with hormonally active tumors. Four patients (40%, 95% confidence interval (CI) 12–74%) achieved the primary endpoint. The objective response rate was 9% (95% CI: 0–41%). The clinical benefit rate was 73% (95% CI: 39–94%). Four patients had grade 3 adverse events related to pembrolizumab. No patients experienced grade 4 or 5 adverse events or a catecholamine crisis. Progression free survival time was 5.7 months (95% CI: 4.37—not reached). The median survival duration was 19 months (95% CI: 9.9—not reached). PDL-1 expression and the presence of infiltrating mononuclear inflammatory cells in the primary tumor did not seem to be associated with disease response. Single-agent pembrolizumab has modest treatment efficacy in patients with progressive MPPGs. Positive responses seemed to be independent of patients’ hereditary backgrounds, tumor hormonal status, and the presence of infiltrating mononuclear inflammatory cells or PDL-1 expression in the primary tumor.

[PMID: 32793409 PMCID: PMC7416339 DOI: 10.1016/j.jbo.2020.100312] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 07/02/2020] [Accepted: 07/22/2020] [Indexed: 12/25/2022] Open
Abstract
It is difficult for clinicians to determine appropriate treatment strategies and predict the prognosis of metastatic spinal pheochromocytoma. Surgical treatment is an effective option in treating MSP and plays an important role in improving patients’ quality of life. Extraosseous metastasis, Tomita score, and number of spinal metastases are all potential prognostic factors for OS and PFS. Individualized treatment plans should be developed based on the actual situation of each patient. Through a multi-disciplinary collaboration and reasonable perioperative management, patients with MSP can be treated more effectively.
Purpose Metastatic spinal pheochromocytoma (MSP) is very rare in clinical practice, with only a few case reports in the literature. Its low incidence makes it profoundly difficult for clinicians to determine appropriate treatment strategies and predict the prognosis. In this study, we analyzed the clinical characteristics, surgical procedure and prognosis of patients with MSP in one of the largest clinical investigations of this entity to date. Methods In this study, we conducted a retrospective analysis of the clinical data of 10 patients with MSP who were treated in our department from 2012 to 2020. We performed a total of 14 operations using two types of surgery: open surgery and percutaneous vertebroplasty. Results Among them, nine patients underwent 14 spinal operations with satisfactory effect and without any perioperative complications. The mean time from the initial operation to detection of spinal metastasis was 85.3 (12–132) months. The average follow-up time was 27.3 months. Disease progression was detected in nine patients, and eight patients (80%) died during the follow-up period. Univariate analysis showed that extraosseous visceral metastasis (P = 0.022), Tomita score (P = 0.027), and number of spinal metastases (P = 0.024) were associated with overall survival (OS). In addition, extraosseous visceral metastasis (P = 0.030), Tomita score (P = 0.013), and number of spinal metastases (P = 0.026) were associated with progression-free survival (PFS). Conclusions Surgical treatment is an effective option in treating MSP and plays an important role in improving patients’ quality of life, due to its efficacy in relieving pain, reconstruction of stability, and restoration of function. Extraosseous metastasis, Tomita score, and number of spinal metastases are all potential prognostic factors for OS and PFS.

Abstract
: Phaeochromocytoma and paraganglioma (PPGL) are chromaffin cell tumours that require timely diagnosis because of their potentially serious cardiovascular and sometimes life- threatening sequelae. Tremendous progress in biochemical testing, imaging, genetics and pathophysiological understanding of the tumours has far-reaching implications for physicians dealing with hypertension and more importantly affected patients. Because hypertension is a classical clinical clue for PPGL, physicians involved in hypertension care are those who are often the first to consider this diagnosis. However, there have been profound changes in how PPGLs are discovered; this is often now based on incidental findings of adrenal or other masses during imaging and increasingly during surveillance based on rapidly emerging new hereditary causes of PPGL. We therefore address the relevant genetic causes of PPGLs and outline how genetic testing can be incorporated within clinical care. In addition to conventional imaging (computed tomography, MRI), new functional imaging approaches are evaluated. The novel knowledge of genotype-phenotype relationships, linking distinct genetic causes of disease to clinical behaviour and biochemical phenotype, provides the rationale for patient-tailored strategies for diagnosis, follow-up and surveillance. Most appropriate preoperative evaluation and preparation of patients are reviewed, as is minimally invasive surgery. Finally, we discuss risk factors for developing metastatic disease and how they may facilitate personalised follow-up. Experts from the European Society of Hypertension have prepared this position document that summarizes the current knowledge in epidemiology, genetics, diagnosis, treatment and surveillance of PPGL.

Abstract
Pheochromocytomas and paragangliomas (PPGLs) are adrenal or extra-adrenal autonomous nervous system-derived tumors. Most PPGLs are benign, but approximately 15% progress with metastases (mPPGLs). mPPGLs are more likely to occur in patients with large pheochromocytomas, sympathetic paragangliomas, and norepinephrine-secreting tumors. Older subjects, those with larger tumors and synchronous metastases, advance more rapidly. Germline mutations of SDHB, FH, and possibly SLC25A11, or somatic MAML3 disruptions relate to a higher risk for metastatic disease. However, it is unclear whether these mutations predict outcome. Once diagnosed, there are no well-established predictors of outcome in mPPGLs, and aggressive tumors have few therapeutic options and limited response. High-specific activity (HSA) metaiodine-benzyl-guanidine (MIBG) is the first FDA approved treatment and shows clinical effectiveness for MIBG-avid mPPGLs. Ongoing and future investigations should involve validation of emerging candidate outcome biomarkers, including somatic ATRX, TERT, and microRNA disruptions and identification of novel prognostic indicators. Long-term effect of HSA-MIBG and the role of other radiopharmaceuticals should be investigated. Novel trials targeting molecular events prevalent in SDHB/FH mutant tumors, such as activated hypoxia inducible factor 2 (HIF2), angiogenesis, or other mitochondrial defects that might confer unique vulnerability to these tumors should be developed and initiated. As therapeutic options are anticipated to expand, multi-institutional collaborations and well-defined clinical and molecular endpoints will be critical to achieve higher success rates in improving care for patients with mPPGLs.

Abstract
Paraganglioma is a tumor that originates from neuroendocrine cells of the sympathetic or parasympathetic systems. Patients may suffer from headaches, palpitations, diaphoresis, and hypertension due to catecholamine excess or symptoms from the mass effect of the tumor. In the absence of typical symptoms of catecholamine excess, the diagnosis of a nonfunctional paraganglioma is often delayed. Herein, we report a case of a 63-year-old female patient with a nonfunctional paraganglioma which is an accidental finding during investigation of a fever. Abdominal ultrasonography incidentally detected this lesion as a complex, solid, cystic mass in the left suprarenal retroperitoneum.

Abstract
OBJECTIVE We aimed to describe clinical course of myelolipoma and to identify predictors of tumour growth and need for surgery. DESIGN A retrospective study. PATIENTS Consecutive patients with myelolipoma. RESULTS A total of 321 myelolipomas (median size, 2.3 cm) were diagnosed in 305 patients at median age of 63 years (range, 25-87). Median follow-up was 54 months. Most myelolipomas were incidentally detected (86%), whereas 9% were discovered during cancer staging and 5% during workup of mass effect symptoms. Thirty-seven (12%) patients underwent adrenalectomy. Compared to myelolipomas <6 cm, tumours ≥6 cm were more likely to be bilateral (21% vs 3%, P < .0001), cause mass effect symptoms (32% vs 0%, P < .0001), have haemorrhagic changes (14% vs 1%, P < .0001) and undergo adrenalectomy (52% vs 5%, P < .0001). Among patients with ≥6 months of imaging follow-up, median size change was 0 mm (-10, 115) and median growth rate was 0 mm/y (-6, 14). Compared to <1 cm growth, ≥1 cm growth correlated with larger initial size (3.6 vs 2.3 cm, P = .02), haemorrhagic changes (12% vs 2%, P = .007) and adrenalectomy (35% vs 8%, P < .0001). CONCLUSIONS Most myelolipomas are incidentally discovered on cross-sectional imaging. Myelolipomas ≥6 are more likely to cause mass effect symptoms, have haemorrhagic changes and undergo resection. Tumour growth ≥1 cm is associated with larger myelolipoma and haemorrhagic changes. Adrenalectomy should be considered in symptomatic patients with large tumours and when there is evidence of haemorrhage or tumour growth.

Abstract
Pheochromocytomas are rare neuroendocrine tumors that can affect people of all ages and are commonly diagnosed in the 4th and 5th decades of life. Familial pheochromocytomas are diagnosed mostly between the 2nd and 3rd decades of life. They can be benign or metastatic and often present as isolated tumors or along with other neuroendocrine syndromes. We present a case of an elderly man who underwent laparoscopic adrenalectomy for pheochromocytoma at the age of 60 years but developed recurrence of metastatic pheochromocytoma after ten years. We also conducted a literature review to understand the epidemiology and presentation of the tumor and to emphasize that there should be a low threshold of suspicion for timely diagnosis and management of recurrent pheochromocytoma.

Abstract
Pheochromocytomas (PCC) and paragangliomas (PGL) are rare neuroendocrine tumors. Pheochromocytomas arise from chromaffin cells in the adrenal medulla, and PGLs arise from chromaffin cells in the ganglia of the autonomic nervous system. Paragangliomas originate from sympathetic or parasympathetic ganglia in the abdomen, thorax, and pelvis. The majority of PCC and sympathetic PGL are endocrine active tumors causing clinical symptoms by secreting excess catecholamines (norepinephrine, epinephrine, dopamine) and their metabolites. The incidence of PCC and PGL ranges between 2 and 8 per million, with a prevalence between 1:2500 and 1:6500. It peaks between the 3rd and 5th decades of life, and approximately 20% of cases are pediatric patients. The prevalence among patients with hypertension in outpatient clinic ranges between 0.1-0.6% in adults and between 2-4.5% in the pediatric age group. 10-49% of these tumors is detected incidentally in imaging techniques performed for other reasons. However, 4-8% of adrenal incidentalomas are PCCs. Of these neuroendocrine tumors, 80-85% are PCCs and 15-20% are PGLs. Up to 40% of patients with PCC and PGL has disease-specific germline mutations and the situation is hereditary. Of 60% of the remaining sporadic patients, at least 1/3 has a somatic mutation in predisposing genes. 8% of the sporadic cases, 20-75% of the hereditary cases, 5% of the bilateral, adrenal cases, and 33% of the extra-adrenal cases at first presentation are metastatic. Although PCCs and PGLs have scoring systems for histological evaluation of the primary tumor, it is not possible to diagnose whether the tumor is malignant since there is no histological system approved for the biological aggressiveness of this tumor group. Metastasis is defined as the presence of chromaffin tissue in non-chromaffin organs, such as lymph nodes, liver, lungs and bone. Although most of the PCC and PGL are benign, the metastatic disease may develop in 15-17%. Metastatic disease is reported between 2-25% in PCCs and 2.4-60% in PGLs. The TNM staging system of the American Joint Committee on Cancer (AJCC) was developed to predict the prognosis, based on the specific anatomical features of the primary tumor and the occurrence of metastasis.

Abstract
PURPOSE OF REVIEW Pheochromocytomas and paragangliomas represent less than 1% of all endocrine tumors. Approximately 15-20% of these tumors are malignant. The definition of malignancy relies on the presence of metastasis. Metastatic pheochromocytomas and paragangliomas are usually advanced, incurable tumors with limited therapeutic options. About 50-60% of these tumors express the noradrenaline transporter in their cell membranes. Recently, the United States Food and Drug Administration approved high-specific-activity iodine 131 metaiodobenzylguanidine (HSA-I-131-MIBG) for the treatment of metastatic pheochromocytomas and paragangliomas that express the noradrenaline transporter. This review reports the benefits and toxicity of HSA-I-131-MIBG, its physical and dosimetric aspects, and radiation safety precautions, as well as its potential therapeutic value for other malignancies (neuroblastoma, gastroenteropancreatic neuroendocrine tumors, and medullary thyroid carcinoma). RECENT FINDINGS A phase 2 clinical trial with HSA-I-131-MIBG reported an impressive clinical benefit rate, acceptable toxicity and long-term benefits. SUMMARY HSA-I-131-MIBG is an effective medication for metastatic pheochromocytomas and paragangliomas that express the noradrenaline transporter.

Abstract
Introduction Paragangliomas (PGGL) are rare neuroendocrine tumors arising from non-epithelial extra-adrenal chromaffin cells. They have been described in different sites: abdomen, pelvis, head, neck and thorax. Incidence is very low, occurring in less than 2–8/million per year. PGGL's of the lung are extremely rare, they have a slow growth and present as painless lesions. Biopsy is the method of choice for diagnosis and prognosis. Presentation of case This is a 70-year-old woman with chronic cough, with a CT-scan showing a 3.3-cm mass in the left lower lobe. After video-assisted thoracic surgery, histologic findings confirmed a non-functioning pulmonary paraganglioma. We present the clinical, radiological, pathological findings and clinical course. Discussion Primary pulmonary PGGL's are extremely rare neuroendocrine tumors with low-grade malignancy, difficult to distinguish from other pulmonary tumors relying only on imaging techniques. In this case, PGGL presented as an incidentaloma during the evaluation of chronic cough. After histological diagnosis, genetic testing are ideally performed to identify somatic or germline mutations that may condition a higher risk of malignancy and metastasis. Conclusion PGGL's must be considered when other diagnoses are unlikely due to immunohistochemistry findings. Larger studies in this field are needed to determine the risk factors for its development and to determine which populations have the greatest potential for malignant transformation Paragangliomas are rare neuroendocrine tumors derived from non-epithelial extra-adrenal chromaffin cells. Paragangliomas from the lung are rare, they have a slow growth and present as non-painful lesions. Complete surgical resection is the diagnostic method of choice for solitary primary pulmonary paragangliomas. Genetic testing is important to identify somatic or germline mutations.
