Comprehensive Investigation of Angiogenesis, PASS Score and Immunohistochemical Factors in Risk Assessment of Malignancy for Paraganglioma and Pheochromocytoma. Diagnostics (Basel) 2024; 14:849. [PMID: 38667494 PMCID: PMC11049119 DOI: 10.3390/diagnostics14080849] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2024] [Revised: 04/02/2024] [Accepted: 04/12/2024] [Indexed: 04/28/2024] Open
Abstract
A challenging task in routine practice is finding the distinction between benign and malignant paragangliomas and pheochromocytomas. The aim of this study is to conduct a comparative analysis of angiogenesis by assessing intratumoral microvascular density (MVD) with immunohistochemical (IHC) markers (CD31, CD34, CD105, ERG), and S100 immunoreactivity, Ki67 proliferative index, succinate dehydrogenase B (SDHB) expressiveness, tumor size with one the most utilized score Pheochromocytoma of Adrenal Gland Scales Score (PASS), using tissue microarray (TMA) with 115 tumor samples, 61 benign (PASS < 4) and 54 potentially malignant (PASS ≥ 4). We found no notable difference between intratumoral MVD and potentially malignant behavior. The group of potentially malignant tumors is significantly larger in size, has lower intratumoral MVD, and a decreased number of S100 labeled sustentacular cells. Both groups have low proliferative activity (mean Ki67 is 1.02 and 1.22, respectively). Most tumors maintain SDHB expression, only 6 cases (5.2%) showed a loss of expression (4 of them in PASS < 4 group and 2 in PASS ≥ 4). PASS score is easily available for assessment and complemented with markers of biological behavior to complete the risk stratification algorithm. Size is directly related to PASS score and malignancy. Intratumoral MVD is extensively developed but it is not crucial in evaluating the malignant potential.

Abstract
Immortalized cell lines originating from tumors and cultured in monolayers in vitro display consistent behavior and response, and generate reproducible results across laboratories. However, for certain endpoints, these cell lines behave quite differently from the original solid tumors. Thereby, the homogeneity of immortalized cell lines and two-dimensionality of monolayer cultures deters from the development of new therapies and translatability of results to the more complex situation in vivo. Organoids originating from tissue biopsies and spheroids from cell lines mimic the heterogeneous and multidimensional characteristics of tumor cells in 3D structures in vitro. Thus, they have the advantage of recapitulating the more complex tissue architecture of solid tumors. In this review, we discuss recent efforts in basic and preclinical cancer research to establish methods to generate organoids/spheroids and living biobanks from endocrine tissues and target organs under endocrine control while striving to achieve solutions in personalized medicine.

Abstract
Background: Pheochromocytoma is a tumor arising from adrenomedullary chromaffin cells. Five-year survival with malignant pheochromocytoma is <50%. Difficulty arises when prescribing for patients, given the potential to precipitate catecholamine crisis, a life-threatening emergency. Clinical Case: A 60-year-old woman presented with abdominal fullness and discomfort. Liver biopsy confirmed pheochromocytoma. Upper and lower abdominal pain was noted and described as "dragging" and "sharp" in nature. The Endocrine Society Clinical Practice guideline for management of pheochromocytoma recommends avoidance of morphine and codeine. Subcutaneous fentanyl was tolerated with good effect, and a continuous subcutaneous infusion was commenced. She was transitioned to a fentanyl patch and her pain was controlled. Conclusion: Symptom control in patients with pheochromocytoma remains challenging. Common opioid analgesics, dopamine-receptor antagonists, corticosteroids, and tricyclic antidepressants are medications known to precipitate a crisis. There is a lack of published research to support the safe prescribing of medications for these patients.

Abstract
Molecular targeted therapy plays an increasingly important role in the treatment of metastatic pheochromocytomas and paragangliomas (PPGLs), which are rare tumors but remain difficult to treat. This mini-review provides an overview of established molecular targeted therapies in present use, and perspectives on those currently under development and evaluation in clinical trials. Recently published research articles, guidelines, and expert views on molecular targeted therapies in PPGLs are systematically reviewed and summarized. Some tyrosine kinase inhibitors (sunitinib, cabozantinib) are already in clinical use with some promising results, but without formal approval for the treatment of PPGLs. Sunitinib is the only therapeutic option which has been investigated in a randomized placebo-controlled clinical trial. It is clinically used as a first-, second-, or third-line therapeutic option for the treatment of progressive metastatic PPGLs. Some other promising molecular targeted therapies (hypoxia-inducible factor 2 alpha [HIF2α] inhibitors, tumor vaccination together with checkpoint inhibitors, antiangiogenic therapies, kinase signaling inhibitors) are under evaluation in clinical trials. The HIF2α inhibitor belzutifan may prove to be particularly interesting for cluster 1B-/VHL/EPAS1-related PPGLs, whereas antiangiogenic therapies seem to be primarily effective in cluster 1A-/SDHx-related PPGLs. Some combination therapies currently being evaluated in clinical trials, such as temozolomide/olaparib, temozolomide/talazoparib, or cabozantinib/atezolizumab, will provide data for novel therapy for metastatic PPGLs. It is likely that advances in such molecular targeted therapies will play an essential role in the future treatment of these tumors, with more personalized therapy options paving the way towards improved therapeutic outcomes.

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

Abstract
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
Purpose Pheochromocytoma (PCC) and adrenocortical carcinoma (ACC) are two rare endocrine diseases. Early diagnosis is crucial to significantly reduce morbidity and mortality. In this study, we used endoscopic ultrasound (EUS) for high-resolution imaging to investigate the endosonographic morphology pattern of PCC and ACC. Materials and Methods This retrospective cohort study included 58 PCC/ACC lesions diagnosed by EUS imaging at two tertiary care centers between 1997 and 2015. The following groups were defined by histology or by the presence of a pheochromocytoma-associated syndrome without histological proof: bPCC (benign PCC), mPCC (malignant PCC), and ACC. Results In our cohort, mPCC tended to be larger at the time of diagnosis (n=5; 39.9±41.9 mm) than bPCC (n=46; 27.3 ±20.8 mm, P=0.548). ACC lesions were significantly larger (n=7; 50.6±14.8 mm) than bPCC and mPCC (n=51; 28.5±23.3 mm, P=0.002). In EUS, bPCC and ACC lesions frequently appeared to have a round shape and nodular structure. bPCC and ACC tended to be more hyperechoic (P=0.112 and P=0.558, respectively) and heterogeneous (P=0.501 and P=0.098, respectively) than mPCC. Compared to PCC, ACC did not show high hyperperfusion (P=0.022). In contrast to adenoma, all tumor entities showed hypo-/anechoic areas within the tumor (P<0.05). Conclusion No significant differences in EUS morphology were found to reliably distinguish benign from malignant PCC and ACC lesions. However, EUS may be a reasonable alternative or complementary method to conventional imaging techniques for the early detection of these tumor entities.

Abstract
OBJECTIVE To explore the surgical strategy and experience of reoperation for pheochromocytoma and paraganglioma which is very challenging. METHODS The clinical data of 7 patients with pheochromocytoma and paraganglioma who underwent reoperation in Department of Urology, Peking University Third Hospital from August 2016 to February 2021 were analyzed retrospectively. There were 4 males and 3 females, with an average age of (44.1±11.5) years (28-60 years), 6 cases on the right side and 1 case on the left side. The causes of the operations included: (1) 2 cases of tumor recurrence after resection; (2) The primary operations failed to completely remove the tumors in 3 cases, because the tumors were large and closely related to blood vessels. (3) Pheochromocytoma and paraganglioma wasn't diagnosed before primary operation, therefore, drug preparation wasn't prepared. Two cases were interrupted by severe blood pressure fluctuations during the primary operations. Imaging evaluation, catecholamine biochemical examination and adequate adrenergic α receptor blockers were administrated in all the cases. The surgical approaches included open transperitoneal surgery in 4 cases, robot-assisted laparoscopy in 1 case and retroperitoneal laparoscopy in 2 cases. The innovative techniques included mobilization of the liver, inferior vena cava transection and anastomosis, and transection of left renal vein. RESULTS The average tumor size was (8.0±3.2) cm (3.6-13.9 cm). The median interval between the reoperation and the primary operation was 9 months (IQR: 6, 19 months). The median operation time was 407 min (IQR: 114, 430 min) and the median blood loss was 1 500 mL (IQR: 20, 3 800 mL). Operations of 5 cases were performed successfully, and 1 case failed only by exploration during the operation. One case died perioperatively. There were 5 cases of intraoperative blood transfusion, the median transfusion volume of red blood cells was 800 mL (IQR: 0, 2 000 mL). One case experienced postoperative lymphorrhagia, and recovered after conservative treatment. The renal function was normal in 2 cases after resection and anastomosis of inferior vena cava or transection of left renal vein. The average postoperative hospital stay was (7.2±3.3) d (4-13 d). The median follow-up time of 6 patients was 33.5 months (IQR: 4.8, 48.0 months). The case who failed in the reoperation still survived with tumor and there was no recurrence in the rest of the patients. CONCLUSION The reoperation of pheochromocytoma and paraganglioma, which can not be resected in the primary operation or recurred postoperatively, is difficult with high risk of hemorrhage, and there is a risk of failure and perioperative death. Different surgical approaches and strategies need to be adopted based on the different situation.

Abstract
BACKGROUND Paragangliomas (PGLs) are rare catecholamine-secreting neuroendocrine tumors, which often present with secondary hypertension. The most common location is the retroperitoneal space. For the first time, we report a rare case of large retroperitoneal compound PGL, and we have innovatively applied a new surgical plan to completely remove the tumor.
CASE SUMMARY A 55-year-old middle-aged man was admitted to the hospital for fluctuating blood pressure for more than 1 year with intermittent headache. He suffered dozens of attacks every day. Blood and urine catecholamines were elevated, somatostatin receptor imaging was positive, and the diagnosis of PGL was clear. The imaging examination revealed a large tumor on the right front of the mediastinal spine at the level of T10-L1 (the posterior space of the right phrenic foot). For the first time in our department, a combined thoracoscopic and laparoscopic operation was used to detect and remove large tumors.
CONCLUSION This is the first reported case of using a thoracoscopic and laparoscopic approach simultaneously to remove a large retroperitoneal compound PGL, which may provide a new surgical approach for similar cases.

Abstract
Introduction Malignant pheochromocytomas are rare endocrine tumors that develop within chromaffin tissue. The diagnosis of malignancy is based on neoplastic recurrence or the presence of metastasis in organs that lack chromaffin tissue. We report a series of four cases because of their diagnostic and therapeutic particularities. Presentation of case we describe four clinical cases of patients with malignant pheochromocytoma whose Menard triad “headache-palpitations-sweating” was present in three out of four patients, the methoxylated derivatives were measured in 4 patients, 3 of which had high values, all of our patients carried out a CT scan which objectified signs of malignancy, MRI was performed on a single patient; presenting with a neoplastic recurrence; looking for a locoregional invasion. Discussion Pheochromocytoma (PC) is a rare neuroendocrine tumor derived from the chromaffin cells of the adrenal medulla. Its annual incidence is 2 to 8 per million adults. A peak frequency is observed between 30 and 40 years of age. Approximately 10% of pheochromocytomas are malignant and in 10% of cases, bilateral localization is observed. Criteria for malignancy include the invasion of neighboring organs, a large tumor, the presence of lymphadenopathy on imaging, or fixation on scintigraphy. Surgery for MAP is not always curative. In the case of multiple liver metastases, treatment is based on adrenalectomy, which can be effectively combined with chemoembolization, cryoablation, or radiofrequency techniques. Conclusion The main prognostic factors of the malignant pheochromocytomas are a large tumor volume, the existence or number of visceral metastases, and the presence of a mutation in the SDHB (Succinate dehydrogenase B) gene. Malignant pheochromocytomas are rare endocrine tumors that develop within chromaffin tissue. A very large part of pheochromocytomas are of genetic origin which can be part of hereditary syndromes. Criteria for malignancy include the invasion of neighboring organs, a large tumor, the presence of lymphadenopathy on imaging, or fixation on scintigraphy. Adequate management of this pathology requires a multidisciplinary consultation meeting

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
BACKGROUND Evidence on follow-up duration for patients with sporadic pheochromocytomas is absent, and current guidelines of the European Society of Endocrinology, American Association of Clinical Endocrinologists and Endocrine Surgeons, and the Endocrine Society are ambiguous about the appropriate duration of follow-up. The aim of this systematic review and meta-analysis is to evaluate the recurrence rate of sporadic pheochromocytomas after curative adrenalectomy. MATERIALS AND METHODS A literature search in PubMed, Embase, and the Cochrane Library was performed. A study was eligible if it included a clear report on the number of sporadic patients, recurrence rate, and follow-up duration. Studies with an inclusion period before 1990, <2 years of follow-up, <10 patients, and unclear data on the sporadic nature of pheochromocytomas were excluded. A meta-analysis on recurrence was performed provided that the heterogeneity was low (I2 < 25%) or intermediate (I2 26-75%). Hozo's method was used to calculate weighted mean follow-up duration and weighted time to recurrence with combined standard deviations (SDs). RESULTS A total of 13 studies, including 430 patients, were included in the synthesis. The meta-analysis results describe a pooled recurrence rate after curative surgery of 3% (95% confidence interval: 2-6%, I2 = 0%), with a weighted mean time to recurrence of 49.4 months (SD = 30.7) and a weighted mean follow-up period of 77.3 months (SD = 32.2). CONCLUSIONS This meta-analysis shows a very low recurrence rate of 3%. Prospective studies, including economical and health effects of limited follow-up strategies for patients with truly sporadic pheochromocytomas should be considered.

Abstract
We describe a rare case of newly discovered pulmonary metastases and surgical confirmation 12 years after initial surgery for a pheochromocytoma. A 61-year-old asymptomatic man was referred because of an abnormal shadow in the right lung field upon chest radiography. Computed tomography (CT) showed two well-demarcated tumors in the basal segment of the right lung. Twelve years previously, he underwent right adrenalectomy and was pathologically diagnosed as having a benign pheochromocytoma. Thereafter, he received a medical check-up annually. To confirm the diagnosis of two pulmonary tumors, video-assisted thoracic surgery was done and wedge resection of the right lower lobe completed. Pathology studies revealed these tumors as pulmonary metastases from the pheochromocytoma, which indicated that the true diagnosis was a malignant pheochromocytoma. Patients with a benign pheochromocytoma should continue to undergo careful monitoring for a long time after the initial surgical procedure. Thoracic surgeons should be aware of the possibility of pulmonary metastases even if >10 years have passed since initial resection of a benign pheochromocytoma.

First Experience Using 18F-Flubrobenguane PET Imaging in Patients with Suspected Pheochromocytoma or Paraganglioma. J Nucl Med 2020; 62:479-485.

Abstract
Pheochromocytomas and paragangliomas are a rare tumor entity originating from adrenomedullary chromaffin cells in the adrenal medulla or in sympathetic, paravertebral ganglia outside the medulla. Small lesions are especially difficult to detect by conventional CT or MRI and even by SPECT with the currently available radiotracers (e.g., metaiodobenzylguanidine [MIBG]). The novel PET radiotracer 18F-flubrobenguane could change the diagnostic paradigm in suspected pheochromocytomas and paragangliomas because of its homology with MIBG and the general advantages of PET imaging. The aim of this retrospective analysis was to evaluate 18F-flubrobenguane in pheochromocytomas and paragangliomas and to investigate the biodistribution in patients. Methods: Twenty-three patients with suspected pheochromocytoma or paraganglioma underwent PET/CT or PET/MRI at 63 ± 24 min after injection of 256 ± 33 MBq of 18F-flubrobenguane. The SUVmean and SUVmax of organs were measured with spheric volumes of interest. Threshold-segmented volumes of interest were used to measure the SUVmean or SUVmax of the tumor lesions. One reader evaluated all cross-sectional imaging datasets (CT or MRI) separately, as well as the PET hybrid datasets, and reported the lesion number and size. The diagnostic certainty for a positive lesion was scored on a 3-point scale. Results: 18F-flubrobenguane showed a reproducible, stable biodistribution, with the highest SUVmax and SUVmean being in the thyroid gland (30.3 ± 2.2 and 22.5 ± 1.6, respectively), pancreas (12.2 ± 0.8 and 9.5 ± 0.7, respectively), and tumor lesions (16.8 ± 1.7 and 10.1 ± 1.1, respectively) and the lowest SUVmax and SUVmean being in muscle (1.1 ± 0.06 and 0.7 ± 0.04, respectively) and the lung (2.5 ± 0.17 and 1.85 ± 0.13, respectively). In a subgroup analysis, a significantly higher average SUVmean was seen for both pheochromocytoma and paraganglioma than for healthy adrenal glands (11.9 ± 2.0 vs. 9.9 ± 1.5 vs. 3.7 ± 0.2, respectively). In total, 47 lesions were detected. The reader reported more and smaller lesions with higher certainty in PET hybrid imaging than in conventional imaging; however, statistical significance was not reached. Of the 23 (23/47, 49%) lesions smaller than 1 cm, 61% (14/23) were found on hybrid imaging only. Conclusion: Our preliminary data suggest 18F-flubrobenguane PET to be a new, effective staging tool for patients with suspected pheochromocytoma or paraganglioma. Major advantages are the fast acquisition and high spatial resolution of PET imaging and the intense uptake in tumor lesions, facilitating detection. Further studies are warranted to define the role of 18F-flubrobenguane PET, particularly in comparison to standard diagnostic procedures such as MRI or 123I-MIBG SPECT/CT.

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
There are less than 150 cases of non-functioning retroperitoneal abdominal schwannoma (NRS) reported. Hormonal assay is crucial in confirming the diagnosis of NRS, as manipulation of a functional retroperitoneal paraganglioma will instigate an abrupt liberation of catecholamines, resulting in devastating consequences. We report the case of 42-year-old woman who presented with headache, night sweats and abdominal discomfort. Cross-sectional imaging demonstrated a retroperitoneal mass adherent to the aorta and inferior vena cava but biochemical testing of blood and urine was negative for metanephrines and normetanephrines. She underwent successful tumour resection via laparotomy, as location increased the complexity and risk of laparoscopic resection.

Abstract
Intro Functional mediastinal paragangliomas arise from extra-adrenal tissues and are rare. These cases create challenges related to diagnosis, peri-operative management, and surgical management. We present a case that demonstrates a planned robot-assisted thoracoscopic resection of a mediastinal paraganglioma that ultimately required a trans-sternal resection of the tumor off the left atrium. Case report Our patient is a 42-year-old male with a prolonged history of refractory hypertension, palpitations, headaches, and diaphoresis, which led to the discovery of a subcarinal functional mediastinal paraganglioma. The patient was brought to the operating room for a right robotic-assisted thoracoscopic subcarinal dissection with attempted resection of the mass. Subsequently, the patient's paraganglioma was successfully resected off the left atrium using a trans-sternal approach, cardiopulmonary bypass, and cardioplegic arrest. He was successfully transitioned to minimal anti-hypertensive medication post-operatively. Discussion Pheochromocytomas are neural-crest derived tumors that typically arise from the adrenal medulla. Rarely, paragangliomas arise in the thoracic cavity, at an approximate incidence of 2%. Our sequential approach offered the potential for a minimally invasive resection, and though initially unsuccessful, safely elucidated the feasibility of resection using cardiopulmonary bypass after confirming no invasion of the airway, esophagus, or other mediastinal structures.

Abstract
Cancer is one of the major health problems of the modern world. With the development of novel biochemistry and analytical instrumentation, precancer diagnosis has become a major focus of clinical and preclinical research. Finding appropriate biomarkers is crucial to make an early diagnosis, before the disease fully develops. With the improvement of precancer studies, cancer biomarkers prove their usefulness in providing important data on the cancer type and the status of patients' progression at a very early stage of the disease. Due to the constant evolution of pediatric cancer diagnosis, which includes highly advanced molecular techniques, the authors have decided to focus on selected groups of neoplastic disease and these include brain tumors, neuroblastoma, osteosarcoma and Hodgkin lymphoma.

Abstract
INTRODUCTION Pheochromocytomas and sympathetic paragangliomas (PPGL) are neuroendocrine catecholamine-secreting tumors that are usually localized. Metastatic disease is rare and systemic treatment consists of conventional chemotherapy and high-specific-activity iodine-131-MIBG which was approved by the FDA in 2018. Although chemotherapy combinations still have value in specific settings, the debilitating side effects of treatment with only modest benefit have limited their use. With the introduction of a new generation of targeted therapy and immunotherapy patients with metastatic PPGL may have improved therapeutic options. AREAS COVERED The current paper presents a case of a patient with metastatic PPGL who received multiple lines of systemic treatment. Despite progression on previous single agent cabozantinib and single agent pembrolizumab on separate clinical trials, the patient has exhibited a major response to the combination of cabozantinib and nivolumab for the past 22 months. In addition, we will review the available therapies for metastatic PPGL and discuss novel agents under clinical development. CONCLUSION Newer targeted therapies and immunotherapy options are under clinical development with promising results for patients with PPGL.

Abstract
Malignant pheochromocytoma (PHEO) can only be fully diagnosed when metastatic foci develop. However, at this point in time, patients gain little benefit from traditional therapeutic methods. Methylation plays an important role in the pathogenesis of PHEO. The aim of this research was to use integrated bioinformatics analysis to identify differentially expressed genes (DEGs) showing aberrant methylation patterns in PHEO and therefore provide further understanding of the molecular mechanisms underlying this condition. Aberrantly methylated DEGs were first identified by using R software (version 3.6) to combine gene expression microarray data (GSE19422) with gene methylation microarray data (GSE43293). An online bioinformatics database (DAVID) was then used to identify all overlapping DEGs showing aberrant methylation; these were annotated and then functional enrichment was ascertained by gene ontology (GO) analysis. The online STRING tool was then used to analyze interactions between all overlapping DEGs showing aberrant methylation; these results were then visualized by Cytoscape (version 3.61). Next, using the cytoHubba plugin within Cytoscape, we identified the top 10 hub genes and found that these were predominantly enriched in pathways related to cancer. Reference to The Cancer Genome Atlas (TCGA) further confirmed our results and further identified an upregulated hypomethylated gene (SCN2A) and a downregulated hypermethylated gene (KCNQ1). Logistic regression analysis and receiver operating characteristic (ROC) curve analysis indicated that KCNQ1 and SCN2A represent promising differential diagnostic biomarkers between benign and malignant PHEO. Finally, clinical data showed that there were significant differences in the concentrations of potassium and sodium when compared between pre-surgery and post-surgery day 1. These suggest that KCNQ1 and SCN2A, genes that encode potassium and sodium channels, respectively, may serve as putative diagnostic targets for the diagnosis and prognosis of PHEO and therefore facilitate the clinical management of PHEO.

Abstract
There are no officially approved therapies for metastatic pheochromocytomas apart from ultratrace 131I-metaiodbenzylguanidine therapy, which is approved only in the United States. We have, therefore, investigated the antitumor potential of molecular-targeted approaches in murine pheochromocytoma cell lines [monocyte chemoattractant protein (MPC)/monocyte chemoattractant protein/3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT)], immortalized mouse chromaffin Sdhb-/- cells, three-dimensional pheochromocytoma tumor models (MPC/MTT spheroids), and human pheochromocytoma primary cultures. We identified the specific phosphatidylinositol-3-kinase α inhibitor BYL719 and the mammalian target of rapamycin inhibitor everolimus as the most effective combination in all models. Single treatment with clinically relevant doses of BYL719 and everolimus significantly decreased MPC/MTT and Sdhb-/- cell viability. A targeted combination of both inhibitors synergistically reduced MPC and Sdhb-/- cell viability and showed an additive effect on MTT cells. In MPC/MTT spheroids, treatment with clinically relevant doses of BYL719 alone or in combination with everolimus was highly effective, leading to a significant shrinkage or even a complete collapse of the spheroids. We confirmed the synergism of clinically relevant doses of BYL719 plus everolimus in human pheochromocytoma primary cultures of individual patient tumors with BYL719 attenuating everolimus-induced AKT activation. We have thus established a method to assess molecular-targeted therapies in human pheochromocytoma cultures and identified a highly effective combination therapy. Our data pave the way to customized combination therapy to target individual patient tumors.

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.

Abstract
BACKGROUND The role of concomitant peptide receptor radionuclide therapy (PRRT) and capecitabine therapy has shown benefit in gastroenteropancreatic neuroendocrine tumors. However, data reporting its role in paraganglioma (PGL) patients is lacking. The aim of this study was to evaluate the role of combined capecitabine and 177Lu-DOTATATE in malignant PGL patients. METHODS In this retrospective, single-institutional, single-arm, observational study, data of consecutive advanced stage PGL patients treated with concomitant 177Lu-DOTATATE-capecitabine therapy, between July 2009 and March 2017, were collected and analyzed. RESULTS Twenty-five PGL patients received an average dose of 22.86 ± 9.54 (14.43-50) GBq 177Lu-DOTATATE and 1250 mg/m2 capecitabine from days 0 to 14, commencing on the morning of PRRT. The median overall survival (OS) was not attained in this patient cohort; however, the median PFS was 32 months. Morphological response according to RECIST 1.1 criteria was achieved in 28% (7/25) patients. Biochemical response with > 50% reduction in chromogranin A levels was observed in 28% of the patients. CONCLUSIONS Our data confirm that 177Lu-DOTATATE-capecitabine therapy is effective in achieving an objective response in 28% and symptomatic response in 43% patients. In comparison to published PRRT monotherapy outcomes in PGL, we did not observe any great advantage of concomitant therapy; however, it could be due to under-powered study. We recommend a large randomized trial to prove or disprove the utility of capecitabine as a radiosensitizer for PRRT in PGL patients.

Abstract
A 57-year-old woman was admitted with lower abdominal pain and bloody bowel discharge. She was diagnosed with rectal tumor by colonoscopy, and a biopsy was performed. Surgery was performed, resulting in a diagnosis of rectal paraganglioma. Since recurrence was confirmed three years later, reoperation was done, and chemotherapy with cyclophosphamide, vincristine and dacarbazine (CVD) was subsequently carried out for further recurrence. After the administration of up to 15 courses of CVD, we delivered best supportive care due to disease progression. She died a year and a half after starting chemotherapy. We herein report this rare disease with a review of the relevant literature.

Abstract
In chromaffin cells, tyrosine hydroxylase (TH), aromatic L-amino acid decarboxylase (AADC), dopamine β-hydroxylase (DBH), and phenylethanolamine N-methyltransferase (PNMT) are mainly involved in catecholamine synthesis. In this study, we evaluated the association between the status of catecholamine-synthesizing enzymes and histopathological features of pheochromocytoma and extraadrenal paraganglioma with special emphasis upon their postoperative clinical behavior. Immunohistochemical evaluation of TH, DBH, AADC, PNMT, Ki 67, and S-100 was performed in 29 pheochromocytoma and 10 extraadrenal paraganglioma and one lymph node harboring metastatic pheochromocytoma. Among these cases, metastasis was subsequently developed in three cases. Urinary normetanephrine (U-NM) levels were significantly higher in clinical metastatic cases than non-metastatic ones. Ki 67 labeling index was significantly higher in both clinical metastatic cases and the Adrenal Gland Scaled Score (PASS) score of ≧ 4 cases than PASS < 4 cases, although this score was originally used in pheochromocytoma. H-score of AADC and DBH were significantly lower in PASS ≧ 4 cases than those with < 4 cases, and in the cases associated with intratumoral necrosis (n = 4), the presence of spindle shaped tumor cells (n = 4), and large nests of cells or diffuse growth (n = 5). Lower status of intratumoral AADC could be related to poor differentiation of tumor cells in both catecholamine production and morphology and could be related to aggressive biological behavior of both pheochromocytoma and extraadrenal paraganglioma.

Abstract
Patients harboring germline mutations in the succinate dehydrogenase complex subunit B (SDHB) gene present with pheochromocytomas and paragangliomas (PPGL) that are more likely malignant and clinically aggressive. The combination chemotherapy cyclophosphamide, vincristine, and dacarbazine (CVD) was retrospectively evaluated in patients with SDHB-associated metastatic PPGL.Query Twelve metastatic PPGL patients harboring SDHB mutations/polymorphisms with undetectable SDHB immunostaining were treated with CVD. CVD therapy consisted of 750 mg/m2 cyclophosphamide with 1.4 mg/m2 vincristine on day 1 and 600 mg/m2 dacarbazine on days 1 and 2, every 21-28 days. Treatment outcome was determined by RECIST criteria as well as determination of response duration and progression-free and overall survivals. A median of 20.5 cycles (range 4-41) was administered. All patients had tumor reduction (12-100% by RECIST). Complete response was seen in two patients, while partial response was observed in 8. The median number of cycles to response was 5.5. Median duration of response was 478 days, with progression-free and overall survivals of 930 and 1190 days, respectively. Serial [18F]-fluorodeoxyglucose positron emission tomography and computed tomography imaging demonstrated continued incremental reduction in maximal standardized uptake values (SUVmax) values in 26/30 lesions. During treatment administration, the median SUV decreased from > 25 to < 6, indicating the efficacy of chemotherapy over a prolonged period of time. Prolonged therapy results in continued incremental tumor reduction, and is consistent with persistent drug sensitivity. CVD chemotherapy is recommended to be considered part of the initial management in patients with metastatic SDHB-related PPGL.

Abstract
Primary Intraosseous Paraganglioma (PGL) of sacrum is highly uncommon. Few of the spinal PGL reported were mostly intradural mass. Paraganglionic tissue is usually not present in the bone. So far, only seven cases of primary intraosseous sacral PGL have been reported in the literature. There are no dependable prognostic histological features to differentiate benign from malignant PGL. The only unequivocal criterion for malignancy is metastasis to an organ where paraganglionic tissue is normally not present. However, an aggressive nature can be identified histologically by loss of architecture, decreased or absent sustentacular cells and Ki-67 index of >3%. We report a case of an elderly male who was admitted with complaints of swelling in the lower back with associated radiating pain and difficulty in sitting of two months duration. A diagnosis of sacral chordoma was made on Magnetic Resonance Imaging (MRI). No other mass was detected elsewhere in his body. The patient underwent surgical excision followed by radiotherapy. On histopathology and immunohistochemistry, a diagnosis of locally aggressive primary intraosseous PGL of sacrum was rendered. Hence, when evaluating a lytic sacral mass, PGL has to be considered as a differential diagnosis.

Abstract
Malignant pheochromocytoma (PHEO) is diagnosed only when metastasis has occurred, making it less likely for patients to obtain the benefits of traditional chemotherapy. Anti-oncogene TP53 mutation has been detected in PHEO and is possibly related to disease progression. However, whether the upregulation of wild-type TP53 has antitumoral effects on PHEO remains completely unknown. In the present study, we used RNA activation (RNAa) technique to upregulate the expression of wild-type TP53 by transfecting synthetic dsP53‑285 into PHEO cell line PC12. We found that the upregulation of wild-type p53 blocked the transition of PC12 cells from the G0/G1 to the S phase, with induction of apoptosis. Additionally, the above-mentioned findings were attested in vivo. Most importantly, dsP53-285-induced antitumoral effects were reversible following co-transfection with siRNA that targeted p53 mRNA. Collectively, our results revealed that the upregulation of p53 and possibly other anti-oncogenes may provide a potential effective therapeutic strategy for PHEO.

Abstract
Abstract
Objective. We conducted an extensive review of the literature and tried to cite the most recent recommendations concerning the pheochromocytoma (PHEO).
Methods. Pub Med and Google Scholar databases were searched systematically for studies concerning pheochromocytomas (intra-adrenal paragangliomas) from 1980 until 2016. Bibliographies were searched to find additional articles.
Results. More than four times elevation of plasma fractionated metanephrines or elevated 24-h urinary fractionated metanephrines are keys to diagnosing pheochromocytoma. If the results are equivocal then we perform the clonidine test. If we have not done it already, we preferably do a CT scan and/or an MRI scan. The patient needs pre-treatment with α1-blockers at least 10–14 days before operation. Alternatives or sometimes adjuncts are Calcium Channels Blockers and/or β-Blockers. Several familial syndromes are associated with PHEO and genetic testing should be considered.
Conclusions. The biggest problem for pheochromocytoma is to suspect it in the first place. Elevated metanephrines establish the diagnosis. With the proper preoperative preparation the risks during operation and the postoperative period are minimal. If there is a risk of the hereditable mutation, it is strongly suggested that all the patients with pheochromocytoma need clinical genetic testing.

Oishi T, Iino K, Okawa Y, Kakizawa K, Matsunari S, Yamashita M, Taniguchi T, Maekawa M, Suda T, Oki Y. DNA methylation analysis in malignant pheochromocytoma and paraganglioma. JOURNAL OF CLINICAL AND TRANSLATIONAL ENDOCRINOLOGY 2016; 7:12-20. [PMID: 29067245 PMCID: PMC5651299 DOI: 10.1016/j.jcte.2016.12.004] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/05/2016] [Revised: 12/07/2016] [Accepted: 12/07/2016] [Indexed: 12/15/2022]
Abstract
AIMS In recent years, aberrant DNA methylation of specific CpG sites has been detected in many types of malignant tumors, and the epigenetic regulation of promoter CpG sites is considered an important mechanism underlying carcinogenesis. This study aimed to establish the epigenetics of the malignant transformation of malignant pheochromocytoma (PCC) and paraganglioma (PGL) by performing a methylation analysis. MATERIALS AND METHODS Based on the results of the Infinium HumanMethylation450 BeadChip array using DNA samples of PCC/PGL patients, candidate CpG sites that were hyper/hypo-methylated in metastatic tumors relative to those in the primary tumors of 2 patients with malignant PCC/PGL were selected. The methylation levels of the chosen candidate CpG sites were evaluated quantitatively. RESULTS Twelve CpG sites were selected as hypermethylated candidates, and 16 CpG sites were selected as hypomethylated candidates. Using two quantitative methylation analysis methods, one hypermethylated site (cg02119938) and one hypomethylated site (cg26870725) remained as candidates. These sites were related to ACSBG1 (acyl-CoA synthetase bubblegum family member 1) and MAST1 (microtubule-associated serine-threonine kinase 1), respectively. Immunohistochemical studies of ACSBG1 and MAST1 revealed that epigenetic changes in the malignant transformation of PCC/PGL might be associated with ACSBG1 silencing or MAST1 overexpression. CONCLUSIONS Here, we report two noteworthy genes, ACSBG1 and MAST1; the aberrant promoter methylation/demethylation of these genes might be involved in their silencing/expression in malignant PCC/PGL. Further investigations are necessary to determine the role of ACSBG1 and/or MAST1 expression in malignant transformation and to establish pathological markers that can evaluate the malignant potential of PCC/PGL.

Abstract
AIMS AND BACKGROUND Primary paragangliomas of nasal cavity and paranasal sinus are rare conditions that could show aggressive behavior with local recurrence and metastasis development. The diagnosis of malignancy is challenging because there are no available histopathologic criteria. In these cases, the prognosis is usually poor. METHODS We report a case of a woman with malignant paranasal sinus paragangliomas. RESULTS The patient was treated with several surgical approaches, radiotherapy, and medical therapy for different recurrences. CONCLUSIONS Despite the malignant behavior of the disease, this patient is still alive many years after first diagnosis.

Abstract
OBJECTIVES To systematically review the incidence and factors associated with recurrences or new tumors after apparent complete resection of pheochromocytoma or thoraco-abdomino-pelvic paraganglioma. DESIGN A systematic review and meta-analysis of published literature was performed. METHODS Pubmed and Embase from 1980 to 2012 were searched for studies published in English on patients with non-metastatic pheochromocytoma or thoraco-abdomino-pelvic paraganglioma, complete tumor resection, postoperative follow-up exceeding 1 month, and recurrence or new tumor documented by pathology, hormonal dosages, or imaging tests. Incidence rates of new events after curative surgery were calculated for each study that had sufficient information and pooled using random-effect meta-analysis. RESULTS In total, 38 studies were selected from 3518 references, of which 36 reported retrospective cohorts from the USA, Europe, and Asia. Patient follow-up was neither standardized nor exhaustive in the included studies. A clear description of patient retrieval methods was available for nine studies and the follow-up protocol and patient flow for four studies. Only two studies used multivariable methods to assess potential predictors of postoperative events.The overall rate of recurrent disease from 34 studies was 0.98 events/100 person-years (95% confidence interval 0.71, 1.25). Syndromic diseases and paragangliomas were consistently associated with a higher risk of a new event in individual studies and in meta-regression analysis. CONCLUSIONS The risk of recurrent disease after complete resection of pheochromocytoma may be lower than that previously estimated, corresponding to five events for 100 patients followed up for 5 years after complete resection. Risk stratification is required to tailor the follow-up protocol after complete resection of a pheochromocytoma or paraganglioma. Large multicenter studies are needed to this end.

Abstract
Neuroendocrine tumors which have the potential to secrete catecholamines are either associated with sympathetic adrenal (pheochromocytoma) or nonadrenal (paraganglioma) tissue. Surgical removal of these tumors is always indicated to cure and prevent cardiovascular and other organ system complications associated with catecholamine excess. Some of these tumors have malignant potential as well. The diagnosis, localization and anatomical delineation of these tumors involve measurement of catecholamines and their metabolic end products in plasma and urine, 123I-metaiodobenzylguanidine scintigraphy, computed tomography, and/or magnetic resonance imaging. Before surgical removal of the tumors, the optimization of blood pressure, as well as intravascular volume, is an important measure to avoid and suppress perioperative adverse hemodynamic events. Preoperative preparation includes the use of alpha-adrenergic antagonists, beta-adrenergic antagonists with or without other antihypertensive agents, fluid therapy as well as insulin therapy for hyperglycemia if required. Due attention should be given to type and dose of alpha-receptor antagonists to be used and the duration of this therapy to achieve an optimal level of preoperative "alpha-blockade." Despite this preoperative preparation, many patients will have hypertensive crises intraoperatively which need to be promptly and carefully managed by the anesthesia team which requires intensive and advanced monitoring techniques. The most common complication after tumor removal is hypotension which may require fluid therapy and vasopressor support for a few hours. With advancement in surgical and anesthetic techniques, the incidence of severe morbidity and mortality associated with the surgery is low in high volume centers.

Abstract
Paragangliomas are rare tumors arising from extra-adrenal chromaffine tissues. The diagnosis of non-functional retroperitoneal paraganglioma and its surgical management can be difficult. We report a case of a retroperitoneal paragangliomaof an unusual localization that renders the surgery more challenging. A 40 year-old woman presented to our department with a four-month history of upper quadrant pain with no vomiting, no fever, nor jaundice. Physical examination was normal. Ultrasonography showed a retro duodenal homogenous mass and computed tomographyscan showed a well-circumscribed round mass of heterogeneous density, which was in close contact with the aorta and the left kidney vein. Laboratory tests were normal. The patient underwent surgical management. The surgical exploration found a retroperitoneal tumor that was encapsulated and showing intimate contact with the abdominal aorta. We performed a complete resection of the tumor. Histological examination of the surgical specimen revealed a paraganglioma. The post operative course was uneventful. Paragangliomas are rare tumors. They can be asymptomatic for a long time and thus be diagnosed at late stage. A follow-up of patients is then essential. Surgical treatment is the only radical treatment and should be performed even in paragangliomas in close contact with the great vessels.

Abstract
Pheochromocytoma (PC) is a neuroendocrine tumor that originates from chromaffin cells of the adrenal medulla. The production of catecholamines, including epinephrine, norepinephrine and dopamine, may lead to haemodynamic instability. Over 30% of PCs are associated with germline mutations, including re-arranged in transfection (RET) mutations seen in multiple endocrine neoplasia type 2 (MEN2) syndromes. Around 40% of individuals with MEN2 develop PC, though it is rarely the presenting feature. Compared to sporadic PC, MEN2-associated PC is more likely to be epinephine secreting and demonstrate bilateral adrenal involvement, and is less likely to be malignant. The diagnosis of PC requires clinical suspicion and biochemical testing, followed by imaging studies. Novel nuclear medicine modalities, including FDG positron emission tomography (PET) and 68Ga DOTATATE PET have added to the conventional techniques of 123I-metaiodobenzylguanindine (MIBG) scintigraphy, computer tomography and magnetic resonance imaging. Treatment of PC is surgical and requires peri-operative alpha and, frequently, beta blockade. Novel surgical techniques, such as adrenal sparing surgery and a laparoscopic approach, have decreased peri-operative morbidity. Surveillance for PC is life long, due to the risk of metastatic disease.

Abstract
OBJECTIVE Malignant phaeochromocytomas are rare and highly aggressive tumours. This retrospective study evaluated the outcome of combined chemotherapy with cyclophosphamide, vincristine and dacarbazine (also known as CVD regimen). METHODS Patients with histologically and radiologically confirmed malignant phaeochromocytoma who were treated with the CVD regimen for progressive disease were retrospectively identified from chart review. Treatment cycles were usually repeated at 21-day intervals, with cyclophosphamide (750 mg/m(2) ), vincristine (1·4 mg/m(2) ) and dacarbazine (600 mg/m(2) ) on day 1, and dacarbazine only (600 mg/m(2) ) on day 2. The main outcome measures were best response during treatment and progression-free survival. RESULTS Eight patients (4 males; median age 55·5 (range 31-77) years) with progressive disease underwent a median of 6 (range 3-11) cycles. Best treatment responses were as follows: partial response, n = 2 (25%); stable disease, n = 3 (38%); and progressive disease, n = 3 (38%). The median progression-free survival was 5·4 (range 2·5-26·8) months. After the initial administration of 6 cycles, two patients received a second course of chemotherapy with another 6 cycles after new progressive disease had been detected. Subsequently, these patients were progression-free for another 6·0 and 6·4 months. Mild gastrointestinal symptoms and fatigue were the most common adverse events. CONCLUSION Although objective tumour response rates were lower than previously reported in small series, the CVD regimen allowed disease stabilization for a substantial period of time and may therefore be considered as a treatment option in advanced stages. To improve disease outcome, however, new therapeutic approaches and larger multicentre studies are needed.

Abstract
Les paragangliomes sont des tumeurs neuroendocrines rares diagnostiquées le plus souvent chez le jeune adulte. Nous rapportons le cas rare d'une jeune femme de 20 ans présentant un paragangliome rétropéritonéal situé sur la face antérolatérale de l'aorte et comprimant l'angle duodéno-jéjunal responsable d'un syndrome subocclusif haut. Dans les formes non sécrétantes, la symptomatologie est souvent déroutante. Le diagnostic n'est généralement fait qu'après examen histologique de la pièce de résection. Le traitement de choix repose sur une chirurgie carcinologique intégrant une concertation multidisciplinaire.

Abstract
Paragangliomas (PGLs) are rare vascular, neuroendocrine tumors of paraganglia, which are associated with either sympathetic tissue in adrenal (pheochromocytomas (PCCs)) and extraadrenal (sympathetic paraganglioma (sPGLs)) locations or parasympathetic tissue of the head and neck paragangliomas (HNPGLs). As HNPGLs are usually benign and most tumors grow slowly, a wait-and-scan policy is often advised. However, their location in the close proximity to cranial nerves and vasculature may result in considerable morbidity due to compression or infiltration of the adjacent structures, necessitating balanced decisions between a wait-and-see policy and active treatment. The main treatment options for HNPGL are surgery and radiotherapy. In contrast to HNPGLs, the majority of sPGL/PCCs produces catecholamines, in advanced cases resulting in typical symptoms and signs such as palpitations, headache, diaphoresis, and hypertension. The state-of-the-art diagnosis and localization of sPGL/PCCs are based on measurement of plasma and/or 24-h urinary excretion of (fractionated) metanephrines and methoxytyramine (MT). sPGL/PCCs can subsequently be localized by anatomical (computed tomography and/or magnetic resonance imaging) and functional imaging studies (123I-metaiodobenzylguanidine-scintigraphy, 111In-pentetreotide scintigraphy, or positron emission tomography with radiolabeled dopamine or dihydroxyphenylalanine). Although most PGL/PCCs are benign, factors such as genetic background, tumor size, tumor location, and high MT levels are associated with higher rates of metastatic disease. Surgery is the only curative treatment. Treatment options for patients with metastatic disease are limited. PGL/PCCs have a strong genetic background, with at least one-third of all cases linked with germline mutations in 11 susceptibility genes. As genetic testing becomes more widely available, the diagnosis of PGL/PCCs will be made earlier due to routine screening of at-risk patients. Early detection of a familial PGL allows early detection of potentially malignant PGLs and early surgical treatment, reducing the complication rates of this operation.

Abstract
The principal function of the adrenal medulla is the production and secretion of catecholamines. During stressful challenging conditions, catecholamines exert a pivotal homeostatic role. Although the main adrenomedullary catecholamine, epinephrine, has a wide array of adrenoreceptor-mediated effects, its absence does not cause life-threatening problems. In contrast, excess production of catecholamines due to an adrenomedullary tumor, specifically pheochromocytoma, results in significant morbidity and mortality. Despite being rare, pheochromocytoma has a notoriously bad reputation because of its potential devastating effects if undetected and untreated. The paroxysmal signs and symptoms and the risks of missing or delaying the diagnosis are well known for most physicians. Nevertheless, even today the diagnosis is still overlooked in a considerable number of patients. Prevention and complete cure are however possible by early diagnosis and appropriate treatment but these patients remain a challenge for physicians. Yet, biochemical proof of presence or absence of catecholamine excess has become more easy and straightforward due to developments in assay methodology. This also applies to radiological and functional imaging techniques for locating the tumor. The importance of genetic testing for underlying germline mutations in susceptibility genes for patients and relatives is increasingly recognized. Yet, the effectiveness of genetic testing, in terms of costs and benefits to health, has not been definitively established. Further improvement in knowledge of genotype-phenotype relationships in pheochromocytoma will open new avenues to a more rationalized and personalized diagnostic approach of affected patients.

Abstract
Pheochromocytomas are rare catecholamine-secreting tumors derived from the sympathetic nervous system. The most common sites of metastasis for pheochromocytoma or extra-adrenal paraganglioma are lymph nodes, bones, lungs, and liver. Patients with known or suspected malignancy should undergo staging with computed tomography (CT) or magnetic resonance imaging as well as functional imaging (e.g. with (123)I/(131)I-MIBG ((131)I-metaiodobenzylguanidine) and (68)Ga-DOTANOC ((68)Ga-labeled [1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid]-1-NaI3-octreotide) positron emission tomography (PET)/CT) to determine the extent and location of disease. We present a case of recurrent malignant pheochromocytoma with unusual site of metastasis in omentum, which was positive on (68)Ga-DOTANOC PET/CT and (131)I-MIBG single-photon emission computed tomography (SPECT/)/CT scintigraphy.

Abstract
Paragangliomas are rare neuroendocrine neoplasms originating from the embryological neural crest. In most cases, they exhibit a benign behavior. Here we report a case of a small symptomatic para-aortic paraganglioma, which was completely removed surgically and a review of the available literature regarding the optimal follow-up of a benign paraganglioma, since no guidelines are currently available for this rare entity.

Abstract
OBJECTIVES To evaluate the management and outcome of children with pheochromocytoma and determine the role of cortex preservation in cases of bilateral disease. METHODS Retrospective review of children, below 12 y of age, with pheochromocytoma managed between November 2003 and December 2012 was done. RESULTS Twelve patients, nine boys and three girls with median age 9 y were enrolled. Eleven (92 %) had adrenal tumors and in one it was extra-adrenal. Five (42 %) had bilateral disease. Ten presented with hypertension, one with headache and one with abdominal pain and fever. All were stabilized pre-operatively with alpha and beta blockers and volume expansion. Six children with unilateral disease underwent total adrenalectomy. Out of five with bilateral disease, one child underwent bilateral total adrenalectomy and was later started on hormone replacement. Remaining four underwent total adrenalectomy on one side and partial on the other side. Post-operatively all became symptom free and normotensive and were off medications within 1 mo. Two children developed recurrence 1 mo post-operatively, one with an initial unilateral pheochromocytoma and one with paraganglionoma. At the last follow up, 10 out of 12(83 %) were disease free while two with recurrence are still awaiting surgery. CONCLUSIONS Surgical resection of pheochromocytoma is effective treatment to achieve cure and prolong survival. Cortex preservation should be done in bilateral disease as risk of recurrence in such cases seems to be of lesser significance as compared to the morbidity and mortality of adrenal insufficiency and consequent lifelong hormone replacement.

Abstract
Purpose: Pheochromocytomas (PCCs) are neuroendocrine tumors arising from the adrenal medulla or as paraganglioma (PGL) from extra-adrenal sites. While usually benign, a small fraction is malignant. Multi-modality therapy is used in treating malignant disease; however, little data exist on the role of external beam radiation therapy (EBRT). In this retrospective review, we assessed response to EBRT in malignant PCCs or PGLs. Methods and Materials: Records of patients treated at the National Institutes of Health who received EBRT between 1990 and 2012 were studied. Patients were assessed for symptomatic control, biochemical response, local and distant control by response evaluation criteria in solid tumors v1.1 or stable disease on imaging reports, toxicity by radiation therapy oncology group (RTOG) criteria, and survival. Results: There were 24 patients treated who received EBRT to lesions of the abdomen (n = 3), central nervous system (n = 4), and bone (n = 40). Lesions were treated with 3D conformal EBRT to a mean dose of 31.8 Gy in 3.3 Gy fractions, or fractionated stereotactic radiosurgery to 21.9 Gy in 13.6 Gy fractions. Patients experienced acute (n = 15) and late (n = 2) RTOG toxicities; no patient experienced acute toxicity ≥4 or late toxicity ≥2. Symptomatic control was achieved in 81.1% of lesions. Stable radiographic response was achieved in 86.7% of lesions with progression in 13%. Distant progression was observed overall in 75% of patients and average survival was 52.4 months. Conclusion: Malignant PCC and PGL often do not respond well to current systemic therapies. In these cases, EBRT can be considered in patients with symptomatic, localized disease progression.

Abstract
Pheochromocytomas of the spine are uncommon and require careful preoperative planning. The authors retrospectively reviewed the charts of 5 patients with metastatic spinal pheochromocytoma who had undergone surgical treatment over the past 10 years at their medical center. They reviewed patient age, history of pheochromocytoma resection, extent and location of metastases, history of alpha blockage, surgical level, surgical procedure, postoperative complications, tumor recurrence, and survival. Metastases involved the cervical (1 patient), thoracic (3 patients), and lumbar (2 patients) levels. Preoperative treatment included primary pheochromocytoma resection, chemotherapy, alpha blockade, embolization, and radiation. Three patients had tumor recurrence, and 2 underwent 2-stage reoperations for tumor extension. Hemodynamic complications were common: 2 patients developed pulseless electrical activity arrest within 4 months after surgery, 1 patient had profound postoperative tachycardia with fever and an elevated creatine kinase level, and 1 patient experienced transient postoperative hypotension and paraplegia. One patient died of complications related to disseminated cerebral and spinal disease.
With careful preoperative and surgical management, patients with symptomatic metastatic spinal pheochromocytoma can benefit from aggressive surgical treatment. Postoperative cardiovascular complications are common even months after surgery, and patients should be closely monitored long term.

Abstract
Classical tumor suppressor genes block neoplasia by regulating cell growth and death. A remarkable puzzle is therefore presented by familial paraganglioma (PGL), a neuroendocrine cancer where the tumor suppressor genes encode subunits of succinate dehydrogenase (SDH), an enzyme of the tricarboxylic acid (TCA) cycle of central metabolism. Loss of SDH initiates PGL through mechanisms that remain unclear. Could this metabolic defect provide a novel opportunity for chemotherapy of PGL? We report the results of high throughput screening to identify compounds differentially toxic to SDH mutant cells using a powerful S. cerevisiae (yeast) model of PGL. Screening more than 200,000 compounds identifies 12 compounds that are differentially toxic to SDH-mutant yeast. Interestingly, two of the agents, dequalinium and tetraethylthiuram disulfide (disulfiram), are anti-malarials with the latter reported to be a glycolysis inhibitor. We show that four of the additional hits are potent inhibitors of yeast alcohol dehydrogenase. Because alcohol dehydrogenase regenerates NAD(+) in glycolytic cells that lack TCA cycle function, this result raises the possibility that lactate dehydrogenase, which plays the equivalent role in human cells, might be a target of interest for PGL therapy. We confirm that human cells deficient in SDH are differentially sensitive to a lactate dehydrogenase inhibitor.

Abstract
Recurrent alterations in promoter methylation of tumor suppressor genes (TSGs) and LINE1 (L1RE1) repeat elements were previously reported in pheochromocytoma and abdominal paraganglioma. This study was undertaken to explore CpG methylation abnormalities in an extended tumor panel and assess possible relationships between metastatic disease and mutation status. CpG methylation was quantified by bisulfite pyrosequencing for selected TSG promoters and LINE1 repeats. Methylation indices above normal reference were observed for DCR2 (TNFRSF10D), CDH1, P16 (CDKN2A), RARB, and RASSF1A. Z-scores for overall TSG, and individual TSG methylation levels, but not LINE1, were significantly correlated with metastatic disease, paraganglioma, disease predisposition, or outcome. Most strikingly, P16 hypermethylation was strongly associated with SDHB mutation as opposed to RET/MEN2, VHL/VHL, or NF1-related disease. Parallel analyses of constitutional, tumor, and metastasis DNA implicate an order of events where constitutional SDHB mutations are followed by TSG hypermethylation and 1p loss in primary tumors, later transferred to metastatic tissue. In the combined material, P16 hypermethylation was prevalent in SDHB-mutated samples and was associated with short disease-related survival. The findings verify the previously reported importance of P16 and other TSG hypermethylation in an independent tumor series. Furthermore, a constitutional SDHB mutation is proposed to predispose for an epigenetic tumor phenotype occurring before the emanation of clinically recognized malignancy.

Abstract
BACKGROUND There are currently no reliable biomarkers for malignant pheochromocytomas and paragangliomas (PPGLs). This study examined whether measurements of catecholamines and their metabolites might offer utility for this purpose. METHODS Subjects included 365 patients with PPGLs, including 105 with metastases, and a reference population of 846 without the tumour. Eighteen catecholamine-related analytes were examined in relation to tumour location, size and mutations of succinate dehydrogenase subunit B (SDHB). RESULTS Receiver-operating characteristic curves indicated that plasma methoxytyramine, the O-methylated metabolite of dopamine, provided the most accurate biomarker for discriminating patients with and without metastases. Plasma methoxytyramine was 4.7-fold higher in patients with than without metastases, a difference independent of tumour burden and the associated 1.6- to 1.8-fold higher concentrations of norepinephrine and normetanephrine. Increased plasma methoxytyramine was associated with SDHB mutations and extra-adrenal disease, but was also present in patients with metastases without SDHB mutations or those with metastases secondary to adrenal tumours. High risk of malignancy associated with SDHB mutations reflected large size and extra-adrenal locations of tumours, both independent predictors of metastatic disease. A plasma methoxytyramine above 0.2nmol/L or a tumour diameter above 5cm indicated increased likelihood of metastatic spread, particularly when associated with an extra-adrenal location. CONCLUSION Plasma methoxytyramine is a novel biomarker for metastatic PPGLs that together with SDHB mutation status, tumour size and location provide useful information to assess the likelihood of malignancy and manage affected patients.
