Auris Nasus Larynx 2024; 51:425-428. [PMID: 38520971 DOI: 10.1016/j.anl.2023.12.002] [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: 06/19/2023] [Revised: 09/20/2023] [Accepted: 12/06/2023] [Indexed: 03/25/2024]
Abstract
The patient, a 40-year-old woman, was diagnosed as having a functional right vagal paraganglioma (PGL) 15 years after undergoing resection for a retroperitoneal PGL. 123I-MIBG scintigraphy showed no accumulation, but as the blood noradrenaline and urinary normetanephrine concentrations were elevated, the tumor was judged as being functional, and surgery was scheduled. The patient was started on doxazosin infusion and embolization of the tumor feeding vessel was performed before the surgery. Intraoperative examination showed that the tumor was contiguous with the vagal nerve, necessitating combined resection of the vagal nerve with the tumor. Postoperatively, the catecholamine levels returned to normal range. Histopathologically, the tumor was diagnosed as a moderately differentiated, intermediate-malignant-grade PGL, with a GAPP score of 4 to 6. No non-chromaffin tissue was observed in the tumor background, so that the functional vagal PGL was considered as a sporadic metachronous tumor rather than as a metastasis from the retroperitoneal PGL. More than half of head and neck paragangliomas (HNPGLs) are reported to arise in the carotid body, and about 5% from the vagal nerve. In addition, HNPGLs rarely produce catecholamines. Herein, we consider the relationship with the previously resected retroperitoneal PGL based on a review of the literature.

Abstract
Pheochromocytomas and paragangliomas (PPGLs) have emerged as one of the most common endocrine tumors. It epitomizes fascinating crossroads of genetic, metabolic, and endocrine oncology, providing a canvas to explore the molecular intricacies of tumor biology. Predominantly rooted in the aberration of metabolic pathways, particularly the Krebs cycle and related enzymatic functionalities, PPGLs manifest an intriguing metabolic profile, highlighting elevated levels of oncometabolites like succinate and fumarate, and furthering cellular malignancy and genomic instability. This comprehensive review aims to delineate the multifaceted aspects of tumor metabolism in PPGLs, encapsulating genetic factors, oncometabolites, and potential therapeutic avenues, thereby providing a cohesive understanding of metabolic disturbances and their ramifications in tumorigenesis and disease progression. Initial investigations into PPGLs metabolomics unveiled a stark correlation between specific genetic mutations, notably in the succinate dehydrogenase complex (SDHx) genes, and the accumulation of oncometabolites, establishing a pivotal role in epigenetic alterations and hypoxia-inducible pathways. By scrutinizing voluminous metabolic studies and exploiting technologies, novel insights into the metabolic and genetic aspects of PPGLs are perpetually being gathered elucidating complex interactions and molecular machinations. Additionally, the exploration of therapeutic strategies targeting metabolic abnormalities has burgeoned harboring potential for innovative and efficacious treatment modalities. This review encapsulates the profound metabolic complexities of PPGLs, aiming to foster an enriched understanding and pave the way for future investigations and therapeutic innovations in managing these metabolically unique tumors.

Abstract
RATIONALE AND OBJECTIVES Using different machine learning models CT-based radiomics to integrate clinical radiological features to discriminating the risk stratification of pheochromocytoma/paragangliomas (PPGLs). MATERIALS AND METHODS The present study included 201 patients with PPGLs from three hospitals (training set: n = 125; external validation set: n = 45; external test set: n = 31). Patients were divided into low-risk and high-risk groups using a staging system for adrenal pheochromocytoma and paraganglioma (GAPP). We extracted and selected CT radiomics features, and built radiomics models using support vector machines (SVM), k-nearest neighbors, random forests, and multilayer perceptrons. Using receiver operating characteristic curve analysis to select the optimal radiomics model, a combined model was built using the output of the optimal radiomics model and clinical radiological features, and its accuracy and clinical applicability were evaluated using calibration curves and clinical decision curve analysis (DCA). RESULTS Finally, 13 radiomics features were selected to construct machine learning models. In the radiomics model, the SVM model demonstrated higher accuracy and stability, with an AUC value of 0.915 in the training set, 0.846 in external validation set, and 0.857 in external test set. Combining the outputs of SVM models with two clinical radiological features, a combined model constructed has demonstrated optimal risk stratification ability for PPGLs with an AUC of 0.926 for the training set, 0.883 for the external validation set, and 0.899 for the external test set. The calibration curve and DCA show good calibration accuracy and clinical effectiveness for the combined model. CONCLUSION Combined model that integrates radiomics and clinical radiological features can discriminate the risk stratification of PPGLs.

Abstract
This case series highlights that extra-adrenal and recurrent pheochromocytomas can require en bloc vascular resection to achieve negative margins. Through this series of cases performed in a multidisciplinary fashion, we aim to highlight the technical aspects of these cases that can add to their complexity. Vascular invasion alone should not preclude an otherwise feasible oncologic resection.

Abstract
Background Prognostic and predictive markers in metastatic pheochromocytoma and paraganglioma (mPPGL) are unknown. We aimed to evaluate epidemiology of mPPGL, and prognostic factors of overall survival (OS) and predictive markers of treatment duration with first-line chemotherapy (TD1L). Patients and methods Retrospective multicentre study of adult patients with mPPGL treated in Latin American centres between 1982 and 2021. Results Fifty-eight patients were included: 53.4% were female, median age at diagnosis of mPPGL was 36 years and 12.1% had a family history of PPGL. The primary site was adrenal, non-adrenal infradiaphragmatic and supradiaphragmatic in 37.9%, 34.5% and 27.6%, respectively. 65.5% had a functioning tumour and 62.1% had metachronous metastases. Positive uptakes were found in 32 (55.2%) 68Gallium positron emission tomography (PET/CT), 27 (46.6%) 2-deoxy-2-[fluorine-18]fluoro-D-glucose PET/CT and 37 (63.8%) of 131Iodine-metaiodobenzylguanidine (MIBG) tests. Twenty-three (40%) patients received first-line chemotherapy, with cyclophosphamide, vincristine and dacarbazine used in 12 (52%) of patients. At a median follow-up of 62.8 months, median TD1L was 12.8 months. Either functional exams, tumour functionality, pathological characteristics or primary tumour location were significantly associated with response or survival. Yet, negative MIBG, Ki67 ≥ 10%, infradiaphragmatic location and functional tumours were associated with numerically inferior OS. Conclusions In patients with mPPGL, prognostic and predictive factors to chemotherapy are still unknown, but negative MIBG uptake, Ki67 ≥ 10%, infradiaphragmatic location and functional tumours were numerically linked to worse OS. Our results should be further validated in larger and independent cohorts.

Abstract
Primary pancreatic paragangliomas are rare. They are mainly non-functional tumours that lack typical clinical manifestations. Definite diagnosis relies on histopathology and immunohistochemistry, and the main treatment is surgery. We report here a case of primary, non-functional, pancreatic paraganglioma in a 49-year-old woman. The tumour was approximately 5.0 × 3.2 ×4.7 cm in size and located in the pancreatic neck and body. We undertook 3D laparoscopic complete resection of the tumour. The patient developed a pancreatic fistula (biochemical leak) post-surgery, but she recovered and was discharged from hospital 11 days after surgery. We describe this case study and briefly summarize previous related reports.

Abstract
Von Hippel-Lindau (VHL) disease is an autosomal dominant disease related to germline mutations in VHL. In VHL disease, pheochromocytoma develops in 10%-20% of patients because of germline mutations and loss of heterozygosity of VHL. However, the rate of paraganglioma associated with VHL is low compared with that of pheochromocytoma, and the reason is unknown. In this study, we performed germline and somatic mutation analyses of retroperitoneal paraganglioma that developed in a patient with clinically diagnosed VHL disease and investigated the tumorigenic mechanism of paraganglioma. The patient was a 25-year-old woman who was considered to have VHL disease on the basis of her family history. She was referred to our clinic to investigate a tumor at the bifurcation of the common iliac artery. The tumor was diagnosed as retroperitoneal paraganglioma by clinical evaluations. A left renal cell carcinoma was also suspected. Polymerase chain reaction direct sequencing analysis and polymorphic microsatellite analysis within the VHL locus suggested that loss of heterozygosity of VHL was associated with paraganglioma and renal cell carcinoma. Multiplex ligation-dependent probe amplification analysis showed a loss of the copy number of VHL exons in paraganglioma. These results suggest that VHL disease contributes to the development of paraganglioma. A literature review showed no reported common missense variants involved in the progression of paraganglioma. The loss of heterozygosity of VHL can be a tumorigenic mechanism of retroperitoneal paraganglioma in VHL disease. However, the low rate of paraganglioma compared with pheochromocytoma is not explained by their genetic background alone.

Abstract
Spontaneous retroperitoneal bleeding is a rare occurrence that might have catastrophic implications. We present a 58-year-old male with a 4-day history of progressively worsening left-sided flank pain due to retroperitoneal hemorrhage from a nonfunctional renal paraganglioma. Abdominal contrast CT scan was helpful in locating the tumor, estimating tumor size and extent of bleeding, visualizing the interaction between the tumor and the surroundings, and ruling out any potential metastasis; however, it lacked specificity in identifying the origin of the mass, needing histologic investigation for a conclusive diagnosis. MRI was not available at our center. We report a rare case of spontaneous retroperitoneal bleeding as a complication of an unusual nonfunctional renal paraganglioma, which was initially misdiagnosed as renal cell carcinoma but later confirmed by postoperative histopathology.

Radical enucleation of the mass was performed, preserving the pancreatic tail. Histologically, a diagnosis of PGL was rendered. Interestingly, two previously unreported mutations, one affecting the KDR gene in exon 7 and another on the JAK3 gene in exon 4 were detected. Both mutations are known to be pathogenetic. Imaging and cytologic findings were blindly reviewed by an expert panel of clinicians, radiologists, and pathologists to identify possible causes of the misdiagnosis. The major issue was lack of evidence of a cleavage plane from the pancreas at imaging, which prompted radiologists to establish an intra-parenchymal origin. The blinded revision shifted the diagnosis towards an extra-pancreatic lesion, as the pancreatic parenchyma showed no structural alterations and no dislocation of the Wirsung duct. Ex post, the identified biases were the emergency setting of the radiologic examination and the very thin mesocolon sheet, which hindered clear definition of the lesion borders. Original endoscopic ultrasonography diagnosis was confirmed, emphasizing the intrinsic limit of this technique in detecting large masses. Finally, pathologic review favored a diagnosis of PGL due to the morphological features and immonohistochemical profile. Eighteen months after tumor excision, the patient is asymptomatic with no disease relapse evident by either radiology or laboratory tests. Our report strongly highlights the difficulties in rendering an accurate pre-operative diagnosis of PGL.

Abstract
Urinary catecholamines (CAs) have been examined for the screening of pheochromocytomas. The decision to perform screening is based on symptoms suggesting secondary hypertension or hyperactivities of the sympathetic nervous system. To elucidate the usefulness of urinary fractions and ratios of CAs, 79 patients in whom 24-h excretions of urinary CAs including adrenaline (AD), noradrenaline (NA) and dopamine (DA) had been examined from 2015 until 2020 were retrospectively analyzed. There were no significant differences in urinary CA levels between two age groups, gender groups and two BMI groups. Patients with histories of preexisting hypertension and diabetes showed significantly higher levels of urinary NA excretion, and the urinary ratio of NA/DA was also increased in the patients with a history of hypertension. Heart rate (HR) was significantly correlated with the urinary ratio of NA/DA. Serum free thyroxine (FT4) concentration and ratio of FT4/thyrotropin (TSH) were correlated with the level of urinary AD. The levels of TSH and FT4/TSH showed negative and positive correlations, respectively, with the urinary NA/DA ratio. Thus, increases of HR are related to the enhanced conversion of DA to NA and increased thyroid hormones are involved in the increase in urinary AD and the conversion of DA to NA. History of lifestyle-related diseases and changes of HR and thyroid functions need to be considered for the evaluation of urinary CAs and their ratios.

Abstract
Pheochromocytomas/paragangliomas are characterized by a unique molecular landscape that allows their assignment to clusters based on underlying genetic alterations. With around 30% to 35% of Caucasian patients (a lower percentage in the Chinese population) showing germline mutations in susceptibility genes, pheochromocytomas/paragangliomas have the highest rate of heritability among all tumors. A further 35% to 40% of Caucasian patients (a higher percentage in the Chinese population) are affected by somatic driver mutations. Thus, around 70% of all patients with pheochromocytoma/paraganglioma can be assigned to 1 of 3 main molecular clusters with different phenotypes and clinical behavior. Krebs cycle/VHL/EPAS1-related cluster 1 tumors tend to a noradrenergic biochemical phenotype and require very close follow-up due to the risk of metastasis and recurrence. In contrast, kinase signaling-related cluster 2 tumors are characterized by an adrenergic phenotype and episodic symptoms, with generally a less aggressive course. The clinical correlates of patients with Wnt signaling-related cluster 3 tumors are currently poorly described, but aggressive behavior seems likely. In this review, we explore and explain why cluster-specific (personalized) management of pheochromocytoma/paraganglioma is essential to ascertain clinical behavior and prognosis, guide individual diagnostic procedures (biochemical interpretation, choice of the most sensitive imaging modalities), and provide personalized management and follow-up. Although cluster-specific therapy of inoperable/metastatic disease has not yet entered routine clinical practice, we suggest that informed personalized genetic-driven treatment should be implemented as a logical next step. This review amalgamates published guidelines and expert views within each cluster for a coherent individualized patient management plan.

Abstract
Pheochromocytomas and paragangliomas are the most heritable endocrine tumors. In addition to the inherited mutation other driver mutations have also been identified in tumor tissues. All these genetic alterations are clustered in distinct groups which determine the pathomechanisms. Most of these tumors are benign and their surgical removal will resolve patient management. However, 5–15% of them are malignant and therapeutical possibilities for them are limited. This review provides a brief insight about the tumorigenesis associated with pheochromocytomas/paragangliomas in order to present them as potential therapeutical targets.

Abstract
BACKGROUND Primary pancreatic paragangliomas are extremely rare tumors. Limited by the diagnostic efficacy of histopathological examination, their malignant behavior is thought to be associated with local invasion or metastasis, with only four malignant cases reported in the literature to date. As pancreatic paragangliomas share similar imaging features with other types of pancreatic neuroendocrine neoplasms, they are difficult to diagnose accurately without the support of pathological evidence. As primary pancreatic paragangliomas are rare, especially those accompanied by lymph node metastasis, there is currently no consensus on treatment. Herein, we report a case of primary pancreatic paraganglioma with lymph node metastasis.
CASE SUMMARY A mass located in the pancreatic body was incidentally discovered on computed tomography in a 41-year-old Tibetan man. Distal pancreatectomy was subsequently performed and a 4.1 cm × 4.2 cm tumor was found embedded in the body of the pancreas during surgery. Histological examination confirmed the characteristics of paraganglioma in which the neoplastic chief cells were arranged in a classic Zellballen pattern under hematoxylin-eosin staining. Further, immunohistochemistry demonstrated that the sustentacular cells in the tumor tissue were positive for S-100 protein, and neoplastic cells and pancreatic draining lymph nodes were positive for chromogranin A and synaptophysin; thus, the presence of lymph node metastasis (two of the eight resected pancreatic draining lymph nodes) was also confirmed. A diagnosis of primary pancreatic paraganglioma with lymph node metastasis was finally established. The patient remained disease-free for 1 year after the surgery.
CONCLUSION A definite diagnosis of pancreatic paraganglioma mainly depends on postoperative histopathological and immunohistochemical examinations. Surgical resection may be the first treatment of choice for patients with primary pancreatic paraganglioma that has metastasized to the lymph nodes.

Abstract
Pheochromocytomas are rare neuroendocrine tumors arising from chromaffin cells in the adrenal medulla. They may occur sporadically or in the context of hereditary syndromes. All pheochromocytomas are considered to have malignant potential (defined as risk of metastasis, not local invasion). The use of grading systems with incorporated clinical and histopathologic parameters can help but not definitively predict the metastatic potential of pheochromocytomas. The recent discovery of susceptibility genes provided new insights into the pathogenesis and introduced additional approaches to estimate the metastatic risk of pheochromocytoma. However, the prevalence of these genetic signatures in pheochromocytomas has yet to be fully addressed. Therefore, in the present study, we retrospectively reviewed cases of pheochromocytoma from 1980 to 2018 in the archives of our institution. Three hundred ninety cases were identified, and their clinicopathologic characteristics and genetic statuses were analyzed. About 25% of the cases had metastases, which were more common in older patients (median, 49 y) than in younger ones. Univariate and multivariate analyses revealed that older age, Hispanic ethnicity, metastasis, and large primary tumor size were markedly associated with poor overall survival. In contrast, family history of pheochromocytoma, lack of symptoms, and bilateral adrenal involvement were associated with better survival. About 37% of the pheochromocytomas were associated with inherited syndromes. About 52% of tested patients had pathogenic mutations of pheochromocytoma susceptibility genes. Of these, succinate dehydrogenase B gene mutation had the strongest association with metastasis. These data support that genetic testing should be offered to all patients with pheochromocytoma.

Abstract
RATIONALE Bladder paraganglioma is characterized by headache, palpitations, hypertension, blurred vision, or sweating during voiding. Transurethral holmium laser resection is a safe and efficacious alternative method for the resection of bladder neoplasms. PATIENT CONCERNS A 24-year-old female had a 2-year history of intermittent headaches, palpitation, and sweating during micturition. DIAGNOSIS Physical examination revealed a rise in the patient's blood pressure to 180/90 mmHg after micturition. Laboratory examination found that the blood catecholamine metabolites were significantly increased. Abdominal ultrasound and computed tomography (CT) scan indicated a 37 mm × 31 mm paraganglioma situated at the right anterolateral wall of the bladder. A diagnosis of bladder paraganglioma was considered based on a comprehensive evaluation of the physical examination, laboratory examination, ultrasound and computerized tomography scan. INTERVENTIONS Preoperative oral administration of a nonselective α-adrenergic receptor antagonist (phenoxybenzamine, 10 mg three times a day,) accompanied by a high-sodium diet and generous fluid intake, was initiated 2 weeks before the surgery to stabilize intraoperative hemodynamics. As the patient was newly married and nulligravid, management with transurethral resection was considered superior to open or partial cystectomy and was selected as the treatment method. OUTCOMES Transurethral holmium resection of the bladder paraganglioma was successfully performed with blood loss less than 20 ml and well-controlled intraoperative blood pressure. The 1-year follow-up results demonstrated well-controlled symptoms. Cystoscopy and evaluation of blood catecholamine metabolites revealed no disease recurrence. LESSONS Transurethral holmium laser resection is a good alternative approach for the resection of bladder paraganglioma, given its advantages of safety and efficacy.

Abstract
BACKGROUND The posterior retroperitoneoscopic approach (PRA) has been under attention as a method for resection of paraganglioma (PGL) for the past few years. However, only a few studies have explored the effectiveness and safety of the PRA for aortocaval and infrarenal PGL resection. METHODS We designed this retrospective study to investigate the safety and effectiveness of the PRA for aortocaval and infrarenal PGL resection in a single center. We retrospectively reviewed the medical records of patients who underwent PRA for PGL resection at our medical center from January 2006 to March 2021. Eight patients were enrolled, of whom six had aortocaval PGL. We investigated the surgical outcomes of enrolled patients. RESULTS The locations of the tumors in relation to the renal vein were: suprarenal in two (25.0%) patients, at the renal vein level in three (37.5%) patients, and infrarenal in three (37.5%) patients. The mean operative time of the enrolled patients was 101.5 ± 39.1 min. The mean postoperative stay was 3.5 ± 1.5 days, and the estimated blood loss was 31.3 ± 51.4 ml. There was one minor complication (chyle leakage), and two hypotensive events occurred during the surgery. Focusing on the results of the renal vein level and infrarenal PGL resection, the mean operative time, mean postoperative stay, and estimated blood loss of the patients were 109.2 ± 41.3 min, 3.5 ± 1.8 days, and 41.7 ± 56.4 ml, respectively. CONCLUSION The PRA for aortocaval and infrarenal PGL resection is feasible and safe. Additional data analysis and long-term follow-up are needed in the future.

Abstract
INTRODUCTION Paragangliomas are infrequent neuroendocrine tumours whose only criterion for malignancy is presence of metastases; thus, all paragangliomas show malignant potential. Actually, different risk factors have been analyzed to predict metastases but they remain unclear. PURPOSE To analyze clinical, histological, and genetic factors to predict the occurrence of metastasis. PATIENTS AND METHOD A multicentre retrospective observational analysis was performed between January 1990 and July 2019. Patients diagnosed with paraganglioma were selected. Clinical, histological, and genetic features were analyzed for the prediction of malignancy. RESULTS A total of 83 patients diagnosed with paraganglioma were included, of which nine (10.8%) had malignant paraganglioma. Tumour size was greater in malignant tumours than in benign (6 cm vs. 4 cm, respectively; p = 0.027). The most frequent location of malignancy was the thorax-abdomen-pelvis area observed in six cases (p = 0.024). No differences were observed in histological differentiation, age, symptoms, and catecholaminergic production. The most frequent genetic mutation was SDHD followed by SDHB but no differences were observed between benign and malignant tumours. In the univariate analysis for predictive factors for malignancy, location, tumour size, and histological differentiation showed statistical significance (p = 0.025, p = 0.014, and p = 0.046, respectively); however, they were not confirmed as predictive factors for malignancy in the multivariate analysis. CONCLUSION In this study, no risk factors for malignancy have been established; therefore, we recommend follow-up of all patients diagnosed with paraganglioma.

Abstract
Context Inherited MYC-associated factor X (MAX) gene pathogenic variants (PVs) increase risk for pheochromocytomas (PCCs) and/or paragangliomas (PGLs) in adults and children. There is little clinical experience with such mutations. Objective This report highlights an important approach. Methods Clinical assessment, including blood chemistry, imaging studies, and genetic testing were performed. Results A 38-year-old Hispanic woman was diagnosed with PCC in 2015, treated with adrenalectomy, and referred to endocrinology clinic. Notably, she presented to her primary care physician 3 years earlier complaining of left flank pain, intermittent diaphoresis, and holocranial severe headache. We confirmed severe hypertension (180/100 mm Hg) over multiple antihypertensive regimens. Biochemical and radiological studies workup revealed high plasma metanephrine of 255 pg/mL (normal range, < 65 pg/mL) and plasma normetanephrine of 240 pg/mL (normal range, < 196 pg/mL). A noncontrast computed tomography scan of the abdomen revealed a 4.2 × 4.3 × 4.9-cm, round-shaped and heterogenous contrast enhancement of the left adrenal gland, and a 2-mm nonobstructive left kidney stone. A presumptive diagnosis of secondary hypertension was made. After pharmacological therapy, laparoscopic left adrenalectomy was performed and confirmed the diagnosis of pheochromocytoma. Based on her age, family history, and a high suspicion for genetic etiology, genetic testing was performed that revealed the presence of a novel likely pathogenic variant involving a splice consensus sequence in the MAX gene, designated c0.64-2A > G. Conclusion The phenotype of MAX PV-related disease and paraganglioma are highlighted. The novel c0.64-2A > G mutation is reported here and should be considered in the diagnostic workup of similar cases.

Laparoscopic resection of a paraganglioma in the greater omentum mimicking a peripancreatic neoplasm: a case report. Clin J Gastroenterol 2021; 14:1364-1370. [PMID: 34053005 DOI: 10.1007/s12328-021-01452-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Accepted: 05/25/2021] [Indexed: 10/21/2022]
Abstract
A paraganglioma is a tumor originating in the sympathetic or parasympathetic nervous system. Its diagnosis may sometimes be confusing if it occurs in an atypical site. We described herein a case of a peripancreatic paraganglioma originating in the greater omentum. An asymptomatic, 61-year-old, female patient was referred to our hospital for detailed examination of a peripancreatic mass detected incidentally on computed tomography (CT). The differential diagnosis was a neuroendocrine neoplasm (NEN), and a biopsy using EUS-FNA was performed. Histologically, the tumor cells showed proliferation in solid cell nests and were positive for CD56, chromogranin A, and synaptophysin. These findings and the hypervascularity of the tumor on imaging studies were compatible with NEN. Since the imaging studies did not clearly demonstrate the continuity of the tumor with the pancreas, laparoscopic tumor resection without a pancreatectomy and sampling of the enlarged peripancreatic lymph nodes were planned as treatment. The absence of continuity with the pancreas was later confirmed by intraoperative observation, and the resection was carried out as planned. The resected tumor was pathologically considered as NEN at first in agreement with the preoperative diagnosis. However, several histological findings (such as a zelleballen-like growth pattern, pseudo-inclusion, and strong nuclear atypia compared with the cells' proliferative ability) were atypical for NEN, and paraganglioma was included in the differential diagnosis. Additional immunostainings of S-100 and AE1/AE3 were performed, leading to the final diagnosis of paraganglioma. Paragangliomas should be included in the differential diagnosis of an intraperitoneal mass of uncertain identity with hypervascularity.

Abstract
Paragangliomas are rare neuroendocrine tumors arising from paraganglion cells in sympathetic or parasympathetic chains, which may develop in the abdomen, chest, skull base, and neck. As paragangliomas have a wide range of imaging features, the diagnosis often requires tissue sampling. We present a unique case of a paraganglioma which originally presented as a rib tumor. A 64-year-old male with right flank pain for 2 months’ was referred for a noncontrast renal colic CT. He was found to have a 3.7 × 3.5 cm soft tissue mass invading the left posterior 9th rib and paraspinal muscle. This was fluorodeoxyglucose F 18, (18F-FDG) avid, with no other distant metabolic activity. He underwent ultrasound-guided core biopsy which revealed a diagnosis of paraganglioma. A right thoracotomy with chest wall resection of 8, 9, and 10 ribs were subsequently performed. The tumor was removed along with a small portion of adherent lung. The tumor was positive for CD56, synaptophysin and chromogranin. S-100 highlighted occasional sustentacular cells, consistent with a pathologic diagnosis of a paraganglioma. The patient remains symptom free for 6 months’ after the operation. Our case highlights that, when paragangliomas occur within the chest wall, they may present as a rib tumor and can mimic metastasis, myeloma or other primary neoplastic etiologies originating from ribs. Both imaging and pathologic diagnosis can be challenging.

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
Background Glutamine metabolism is considered an important metabolic phenotype of proliferating tumor cells. Objective The objective of this study was to investigate the expression of glutamine metabolism-related and amino acid transporter proteins in adrenal cortical neoplasms (ACNs) and pheochromocytomas (PCCs) in the adrenal gland. Methods A tissue microarray was constructed for 132 cases of ACN (115 cases of adrenal cortical adenoma and 17 cases of adrenal cortical carcinoma) and 189 cases of PCC. Immunohistochemical staining for glutamine metabolism-related proteins GLS1 and GDH and amino acid transporter proteins SLC1A5, SLC7A5, and SLC7A11 as well as SDHB was performed and compared with clinicopathologic parameters. Results The expression levels of GLS (p < 0.001), SLC7A5 (p = 0.049), and SDHB (p = 0.007) were higher in ACN than in PCC, whereas the expression levels of SLC1A5 (p < 0.001) and SLC7A11 (p < 0.001) were higher in PCC than in ACN. In ACN, GLS positivity was associated with a higher Fuhrman grade (p = 0.009), and SLC1A5 positivity was associated with SDHB positivity (p = 0.004) and a clear cell proportion < 25% (p = 0.010). SDHB negativity was also associated with tumor cell necrosis (p = 0.007). In PCC, SLC7A11 positivity was associated with nonnorepinephrine type (p = 0.008). In Kaplan-Meier analysis, patients with GLS positivity (p = 0.039) and SDHB negativity (p = 0.005) had significantly shorter overall survival in ACN. In PCC patients with a GAPP score ≥ 3, GLS positivity (p = 0.001) and SDHB positivity (p = 0.001) were associated with shorter disease-free survival, whereas GLS positivity (p = 0.004) was also associated with shorter overall survival. Conclusions The expression of glutamine metabolism-related and amino acid transporter proteins in ACN and PCC is distinct and associated with prognosis.

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.

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
Pheochromocytomas are rare neuroendocrine neoplasms that require adequate preoperative evaluation in order to prevent and lessen the serious complications of catecholamine hypersecretion. Preoperative management contributes to reducing morbidity and mortality rates in patients who have not been diagnosed with this condition and undergo any surgery. However, current mortality seems to be lower, a fact attributed to preoperative management with alpha blockers.

Abstract
OBJECTIVE Paragangliomas are rare tumours of neural crest origin that express high levels of somatostatin receptor. Ga-68 DOTATATE PET/CT is a widely accepted method for imaging of neuroendocrine tumours. This study was performed to review a Ga-68 DOTATATE PET/CT patient database and to establish the impact of the modality on patient treatment. METHODS Demographic data, imaging data and change in management after Ga-68 DOTATATE PET/CT were evaluated. RESULTS Ga-68 DOTATATE PET/CT scans were performed in 21 patients in whom paragangliomas had been confirmed after biopsy or surgery and in one patient with suspected paraganglioma. In most patients, the primary site was the organ of Zuckerkandl (12/22). Of the 22 Ga-68 DOTATATE PET/CT scans completed, 19 (86.4%) were positive and three (13.6%) negative. In 12 of 14 recurrent cases (90.9%), the treatment plan was changed after the Ga-68 DOTATATE PET/CT scan owing to new, unexpected findings, while it remained unchanged in two (9.1%). Regarding the change in treatment plan, in most instances the new treatment comprised peptide receptor radionuclide therapy (PRRT). CONCLUSION Ga-68 DOTATATE PET/CT findings led to a change in the scheduled treatment plan in 90.9% of patients with suspected recurrence. The most frequent change consisted in initiation of PRRT due to disease recurrence or progression or detection of multiple metastases.

Abstract
Given the complexity and diversity of the cancer genomics profiles, it is challenging to identify distinct clusters from different cancer types. Numerous analyses have been conducted for this propose. Still, the methods they used always do not directly support the high-dimensional omics data across the whole genome (Such as ATAC-seq profiles). In this study, based on the deep adversarial learning, we present an end-to-end approach ClusterATAC to leverage high-dimensional features and explore the classification results. On the ATAC-seq dataset and RNA-seq dataset, ClusterATAC has achieved excellent performance. Since ATAC-seq data plays a crucial role in the study of the effects of non-coding regions on the molecular classification of cancers, we explore the clustering solution obtained by ClusterATAC on the pan-cancer ATAC dataset. In this solution, more than 70% of the clustering are single-tumor-type-dominant, and the vast majority of the remaining clusters are associated with similar tumor types. We explore the representative non-coding loci and their linked genes of each cluster and verify some results by the literature search. These results suggest that a large number of non-coding loci affect the development and progression of cancer through its linked genes, which can potentially advance cancer diagnosis and therapy.

Abstract
Thymoma and paraganglioma are known causes of mediastinal masses, the latter being extremely rare. Thymomas arise from remnant thymic tissue in the anterior mediastinum; whereas, thoracic paragangliomas arise from para-aortic or para-vertebral sympathetic chain ganglion (derivatives of embryonic neural crest) in the middle or posterior mediastinum. We report a case of a middle-aged woman with two mediastinal masses, originally believed to be a single tumor or primary malignancy with adjacent metastasis on Computed Tomography (CT) that were further delineated with Magnetic Resonance Imaging (MRI) and [68Ga]-DOTA-(Tyr3)-octreotate (DOTA-TATE) Positron Emission Tomography-Computed Tomography (PET-CT) and surgical pathology as two distinct entities: left epicardial paraganglioma and anterior mediastinal thymoma. A comprehensive discussion of both entities is included.

Abstract
INTRODUCTION Paraganglioma of the urinary bladder is a very rare disease accounting for 0.06% of all bladder tumors. Owing to their rarity and symptomatic variability, preoperative diagnosis is often difficult. CASE PRESENTATION A 70-year-old male was referred to our department for hematuria. Cystoscopy showed a non-papillary broad-based tumor. Computed tomography and magnetic resonance imaging revealed a 32-mm bladder tumor at the top of the bladder, which suggested muscle-invasive bladder tumor. We diagnosed muscle-invasive bladder cancer or urachal carcinoma, and transurethral resection of the bladder tumor was performed. At the initiation of transurethral resection of the bladder tumor, the systolic blood pressure was elevated to over 200 mmHg. The pathological findings revealed paraganglioma of the urinary bladder, and afterward, a partial cystectomy was performed. CONCLUSION We herein reported the case of paraganglioma in the bladder whose blood pressure became extremely elevated during transurethral resection of the bladder tumor. In addition, we analyzed important factors for preoperative diagnosis using 162 cases reported in Japan.

Abstract
The present study aims to raise awareness about the necessity of a thorough differential diagnosis process when diagnosing paraganglioma as it is an extremely rare entity with a high malignant potential. A 64-year-old female patient was admitted to the hospital with symptoms of bowel obstruction and a palpable abdominal mass. Abdominal and pelvic computed tomography revealed a cystic heterogeneously enhanced mass. The tumor was surgically removed and then microscopically analysed. Microscopically, the mass was composed of nests of small polygonal and round cells with central vesicular nuclei, consistent with the diagnosis of mesenteric paraganglioma which was later confirmed by immunohistochemistry. The critical markers for paragangliomas, namely chromogranin A and S100, should be used as the first step in diagnosis, followed by other valuable immunohistochemical markers. A long-term follow-up is extremely important following the diagnosis of paraganglioma as all these tumors have a malignant potential.

Abstract
BACKGROUND AND OBJECTIVES The International Collaboration on Cancer Reporting (ICCR) is a not-for-profit to develop evidence-based, internationally agreed-upon standardized data sets for each anatomic site, to be used throughout the world. Providing global standardization of pathology tumor classification, staging, and other reporting elements will lead to improved patient management and enhanced epidemiological research. METHODS Pheochromocytoma and paraganglioma are uncommon and are frequently overlooked in registry data sets. Malignant criteria have previously been defined only when there was metastatic disease. RESULTS With recent recognition of a significant inheritance association and the development of risk stratification tools, this data set was created in order to obtain more meaningful outcomes and management data, using similar criteria across the global pathology community. Issues related to key core and non-core elements, especially clinical hormonal status, familial history, tumor focality, proliferative fraction, adverse or risk stratification features, and ancillary techniques, are discussed in the context of daily application to these types of specimens. CONCLUSIONS The ICCR data set, developed by an international panel of endocrine organ specialists, establishes a pathology-standardized reporting guide for pheochromocytoma and paraganglioma.

Abstract
Bladder paragangliomas are rare tumors, with no prospective studies or guidelines on the management of this disease. We present a case series of 6 patients managed with bladder preservation over a median follow-up period of 124 months. We also present a review of the recent literature on bladder paragangliomas. We aim to provide a timely synthesis of the recent evidence on bladder paragangliomas as changing paradigms necessitate individualized treatment.

Abstract
CONTEXT We describe a patient with metastatic malignant pheochromocytoma who was found to have germline SDHB and TP53 mutations occurring together. CASE DESCRIPTION A 39-year-old male presented with neck pain. Magnetic resonance imaging of the neck revealed a C3 vertebral body collapse and an underlying C3 lesion. Computed tomography (CT) of the thorax, abdomen, and pelvis showed multiple skeletal lesions, a sternal mass, bilateral pulmonary nodules, bilateral adrenal masses, and an aortocaval lymph node conglomerate. He underwent biopsy of the sternal mass, which revealed metastatic pheochromocytoma and subsequent blood work showed serum epinephrine levels of 200 pg/mL (normal 10-200 pg/mL), norepinephrine 28 241 pg/mL (normal 80-520 pg/mL), and dopamine 250 pg/mL (normal 0-20 pg/mL). Genetic testing revealed both SDHB and TP53 germline mutations. He was started on α- and β-blockers and calcium channel blockers to control hypertension and tachycardia. Two months after the diagnosis, a CT of the abdomen and pelvis showed progression of disease, with enlargement of the right adrenal mass as well as the aortocaval conglomeration. His plasma metanephrines were significantly elevated. He was started on systemic chemotherapy with cyclophosphamide, dacarbazine, and vincristine. He required several antihypertensive agents, including metyrosine, to control his blood pressure in preparation for chemotherapy. CONCLUSION This is the first reported case of simultaneous SDHB and TP53 germline mutations occurring in an individual with a highly aggressive clinical course of pheochromocytoma. We speculate that the simultaneous occurrence of these 2 oncogenic mutations may have led to an aggressive tumor progression.

Abstract
Background Pheochromocytoma (PCC) and Paraganglioma (PGL) are rare neuroendocrine neoplasms. These tumors harbour disastrous consequences during surgery due to catecholamine hypersecretion if they are undiagnosed or prepared inadequately preoperatively. Case presentation A 41- year- old lady presented with mild left flank discomfort. She had experienced recurrent anxiety attacks accompanied by palpitations and headache which were managed previously as panic attacks. Radiologic investigations showed a retroperitoneal mass that located anteromedial to the left kidney, separated from the left adrenal gland and adherent to the 4th duodenal segment. During admission, her vital signs showed slight elevation of blood pressure (140\90–160\110) mmHg, thus 24-h urine metanephrine and normetanephrine were requested and the results revealed normal values. Upper gastrointestinal endoscopy failed to pass beyond the 3th duodenal segment and showed no pathologic evidence. According to her findings, a diagnosis of duodenal gastrointestinal stromal tumor (GIST) was suspected. During laparotomy, crises of hypertension and tachycardia followed by severe hypotension made the resection of the misdiagnosed mass very tricky. Immunohistochemical staining studies confirmed the diagnosis of paraganglioma. Conclusion Paraganglioma is a life threatening disease and should always be considered as a differential diagnosis of asymptomatic retroperitoneal mass. The aim of our study is to present a challenging case of an undiagnosed retroperitoneal paraganglioma and to alarm our colleagues from such troubles.

Abstract
CONTEXT Prognosis of metastatic pheochromocytoma/paraganglioma following 131-Iodine metaiodobenzylguanidine (MIBG) is incompletely characterized due to small samples and shorter follow-up in these rare, often indolent tumors. OBJECTIVE To describe long-term survival, frequency, and prognostic impact of imaging, biochemical, and symptomatic response to 131-I MIBG. DESIGN Retrospective chart and imaging review at a tertiary referral center. PATIENTS Six hundred sixty-eight person-years of follow-up in 125 patients with metastatic pheochromocytoma/paraganglioma with progression through prior multimodal treatment. INTERVENTION Median 18 800 MBq 131-I MIBG. MAIN OUTCOME MEASURES Overall survival, Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST) imaging response, symptomatic response per chart review, and biochemical response (20% change over 2 consecutive assays of catecholamines, vanillylmandelic acid, metanephrines, or chromogranin A). RESULTS Median survival standard deviation [SD] from diagnosis was 11.5 years [2.4]; following metastasis, 6.5 years [0.8]; post treatment, 4.3 years [0.7]. Among 88 participants with follow-up imaging, 1% experienced complete response, 33% partial response, 53% stability, and 13% progression. Fifty-one percent showed subsequent progression, median progression-free survival [SD] of 2.0 years [0.6]. Stability/response vs progression at first imaging follow-up (3-6 months) predicted improved survival, 6.3 vs 2.4 years (P = 0.021). Fifty-nine percent of 54 patients demonstrated biochemical response. Fifty percent of these relapsed, with median time to laboratory progression [SD] of 2.8 years [0.7]. Biochemical response did not predict extended survival. Seventy-five percent of 83 patients reported improvement in pretreatment symptoms, consisting primarily of pain (42%), fatigue (27%), and hypertension (14%). Sixty-one percent of these patients experienced subsequent symptomatic progression at median [SD] 1.8 years [0.4]. Symptomatic response did not predict extended survival. CONCLUSIONS Imaging, symptomatic, and laboratory response to multimodal treatment including high-dose 131-I MIBG were achieved on long-term follow-up in metastatic pheochromocytoma or paraganglioma. Imaging response at 3 to 6 months was prognostic.

Abstract
Pheochromocytoma and paraganglioma (PPGL) are rare neuroendocrine tumors that arising from the adrenal medulla or extra-adrenal autonomic ganglia. Traditionally, PPGL was classified as benign or malignant based on the presence of distant metastasis at the time of initial surgery. However, according to WHO 2017 Classification of Tumors of Endocrine Organs, all PPGL has metastatic potential. The term "metastatic" is used, replacing "malignant" in this group of tumors. The prediction of PPGL's metastatic potential is a clinical concern, although many relevant indicators such as genetics, histology, pathology and molecular biology markers have been proved to be related to the metastasis of PPGL, but none of them is 100% predictive; various types of prediction systems had been created, but previous studies had demonstrated that they still need to be validated in multicenter studies. There is no unified clinical standard to differentiate metastatic from non-metastatic and a highly effective prediction system is of urgent need. In this review, we summarized all reported prediction systems, including the PASS system, the GAPP system, the COPPs system and the ASES system. Additional potential indicators that related to metastatic PPGL were also introduced.

Abstract
Pheochromocytomas and paragangliomas (PHEO/PGL) are rare but occasionally life-threatening neoplasms, and are potentially malignant according to WHO classification in 2017. However, it is also well known that histopathological risk stratification to predict clinical outcome has not yet been established. The first histopathological diagnostic algorithm for PHEO, "PASS", was proposed in 2002 by Thompson et al. Another algorithm, GAPP, was then proposed by Kimura et al. in 2014. However, neither algorithm has necessarily been regarded a 'gold standard' for predicting post-operative clinical behavior of tumors. This is because the histopathological features of PHEO/PGL are rather diverse and independent of their hormonal activities, as well as the clinical course of patients. On the other hand, recent developments in wide-scale genetic analysis using next-generation sequencing have revealed the molecular characteristics of pheochromocytomas and paragangliomas. More than 30%-40% of PHEO/PGL are reported to be associated with hereditary genetic abnormalities involving > 20 genes, including SDHXs, RET, VHL, NF1, TMEM127, MAX, and others. Such genetic alterations are mainly involved in the pathogenesis of pseudohypoxia, Wnt, and kinase signaling, and other intracellular signaling cascades. In addition, recurrent somatic mutations are frequently detected and overlapped with the presence of genetic alterations associated with hereditary diseases. In addition, therapeutic strategies specifically targeting such genetic abnormalities have been proposed, but they are not clinically applicable at this time. Therefore, we herein review recent advances in relevant studies, including histopathological and molecular analyses, to summarize the current status of potential prognostic factors in patients with PHEO/PGL.

Abstract
Pheochromocytoma (PCC) and paraganglioma (PGL) are rare neuroendocrine tumors associated with high cardiovascular morbidity and variable risk of malignancy. The current therapy of choice is surgical resection. Nevertheless, PCCs/PGLs are associated with a lifelong risk of tumor persistence or recurrence. A high rate of germline or somatic mutations in numerous genes has been found in these tumors. For some, the tumorigenic processes are initiated during embryogenesis. Such tumors carry gene mutations leading to pseudohypoxic phenotypes and show more immature characteristics than other chromaffin cell tumors; they are also often multifocal or metastatic and occur at an early age, often during childhood. Cancer stem cells (CSCs) are cells with an inherent ability of self-renewal, de-differentiation, and capacity to initiate and maintain malignant tumor growth. Targeting CSCs to inhibit cancer progression has become an attractive anti-cancer therapeutic strategy. Despite progress for this strategy for solid tumors such as neuroblastoma, brain, breast, and colon cancers, no substantial advance has been made employing similar strategies in PCCs/PGLs. In the current review, we discuss findings related to the identification of normal chromaffin stem cells and CSCs, pathways involved in regulating the development of CSCs, and the importance of the stem cell niche in development and maintenance of CSCs in PCCs/PGLs. Additionally, we examine the development and feasibility of novel CSC-targeted therapeutic strategies aimed at eradicating especially recurrent and metastatic tumors.

Abstract
Pheochromocytomas and extra-adrenal paragangliomas are rare neuroendocrine neoplasms with characteristic histologic and immunohistochemical features. These tumors can arise in several anatomic locations, necessitating that their diagnostic recognition extends beyond the realm of endocrine disorders. A practical and reproducible risk stratification system for these tumors is still in development. In this rapidly evolving era of molecular medicine, it is essential for pathologists to equip themselves with a framework for understanding the classification of paragangliomas and pheochromocytomas and be informed of how they might advise their colleagues with regard to prognostication and appropriate follow-up.

Abstract
Pheochromocytomatosis is defined as a multifocal cell dissemination limited to the operatively opened space with no signs of distant metastasis. After primary adrenalectomy due to a pheochromocytoma this is a rare and underrecognized manifestation of a tumor recurrence. Between 2010 and 2019 a total of 5 patients with the presentation of pheochromocytomatosis were treated in this center. Clinical and survival data were compared to 12 patients with a metastasized pheochromocytoma. Patients presenting with pheochromocytomatosis showed a better but not significant overall survival (136.8 vs. 107 months). Furthermore, patients with pheochromocytomatosis presented more often with a noradrenaline secretion type. Tumor recurrence in the pheochromocytomatosis group occurred on average 69.2 months after the initial diagnosis and was therefore much later than in patients with distant metastases from a pheochromocytoma (39 months, p = 0.13). This article outlines this special manifestation of recurrence of a pheochromocytoma based on this patient collective. Besides technical operative aspects there appears to be evidence for tumor-specific factors that promote the development of pheochromocytomatosis. Importantly, it seems that all patients with a pheochromocytoma should receive lifelong aftercare and that patients should be closely monitored during the first 5 years after surgery.

Current Management of Pheochromocytoma/Paraganglioma: A Guide for the Practicing Clinician in the Era of Precision Medicine. Cancers (Basel) 2019; 11:cancers11101505.

Abstract
Pheochromocytomas and paragangliomas (PCC/PGLs) are rare, mostly catecholamine-producing neuroendocrine tumors of the adrenal gland (PCCs) or the extra-adrenal paraganglia (PGL). They can be separated into three different molecular clusters depending on their underlying gene mutations in any of the at least 20 known susceptibility genes: The pseudohypoxia-associated cluster 1, the kinase signaling-associated cluster 2, and the Wnt signaling-associated cluster 3. In addition to tumor size, location (adrenal vs. extra-adrenal), multiplicity, age of first diagnosis, and presence of metastatic disease (including tumor burden), other decisive factors for best clinical management of PCC/PGL include the underlying germline mutation. The above factors can impact the choice of different biomarkers and imaging modalities for PCC/PGL diagnosis, as well as screening for other neoplasms, staging, follow-up, and therapy options. This review provides a guide for practicing clinicians summarizing current management of PCC/PGL according to tumor size, location, age of first diagnosis, presence of metastases, and especially underlying mutations in the era of precision medicine.

Malignant Pheochromocytomas/Paragangliomas and Ectopic Hormonal Secretion: A Case Series and Review of the Literature. Cancers (Basel) 2019; 11:cancers11050724.

Abstract
Malignant pheochromocytomas (PCs) and paragangliomas (PGLs) are rare neuroendocrine neoplasms defined by the presence of distant metastases. There is currently a relatively paucity of data regarding the natural history of PCs/PGLs and the optimal approach to their treatment. We retrospectively analyzed the clinical, biochemical, imaging, genetic and histopathological characteristics of fourteen patients with metastatic PCs/PGLs diagnosed over 15 years, along with their response to treatment. Patients were followed-up for a median of six years (range: 1–14 years). Six patients had synchronous metastases and the remaining developed metastases after a median of four years (range 2–10 years). Genetic analysis of seven patients revealed that three harbored succinate dehydrogenase subunit B/D gene (SDHB/D) mutations. Hormonal hypersecretion occurred in 70% of patients; normetanephrine, either alone or with other concomitant hormones, was the most frequent secretory component. Patients were administered multiple first and subsequent treatments including surgery (n = 12), chemotherapy (n = 7), radionuclide therapy (n = 2) and radiopeptides (n = 5). Seven patients had stable disease, four had progressive disease and three died. Ectopic hormonal secretion is rare and commonly encountered in benign PCs. Ectopic secretion of interleukin-6 in one of our patients, prompted a literature review of ectopic hormonal secretion, particularly from metastatic PCs/PGLs. Only four cases of metastatic PC/PGLs with confirmed ectopic secretion of hormones or peptides have been described so far.
