Beta-Adrenergic Blockade Decreases the Neuroimmune Changes in Mice Induced by Cohabitation with an Ehrlich Tumor-Bearing Cage Mate.

Neuroimmunomodulation. 2017 Aug 09;:

Authors: Margatho RO, Massoco CO, Calefi AS, Cruz DSG, Sandini TM, Alves GJ, Florio JC, Palermo-Neto J

Abstract
OBJECTIVES: Cohabitation with Ehrlich tumor-bearing (ETB) mice induced behavioral, neurochemical, hormonal, and immune effects in the conspecifics as a consequence of stress-induced activation of the sympathetic nervous system (SNS) with catecholamine release. In the current study, the nonspecific β-AR blocker d,l-propranolol and the specific β2-AR blocker ICI-118.551 were employed as pharmacological tools to assess the extent to which catecholamines participated in the effects induced by cohabitation with ETB mice.
METHODS: Two experiments were performed, 1 with d,l-propranolol treatment and the other with ICI-118.551. One mouse in the experimental group was called the "companion of the sick partner" (CSP) since it was forced to live in the same cage with 2 (experiment 1) or 1 (experiment 2) cage mate that had been i.p. injected with 5 × 106 Ehrlich tumor cells.
RESULTS: The d,l-propranolol treatment, but not the ICI-118.551 treatment, attenuated the effects of cohabitation with 2 ETB mice on both open-field behavior and the hypothalamic levels and turnover rate of norepinephrine. The 2 β-AR blockers were unable to change the serum corticosterone levels and adrenal weights of the CSP mice; however, these drugs abrogated the effects of cohabitation on neutrophil oxidative burst and phagocytosis. Finally, an increase in the 5-HT turnover rate was observed in the olfactory bulb of CSP mice compared to their respective controls, an effect that was not modified by β-AR blockade.
CONCLUSION: These results confirm and strengthen our hypothesis that the SNS is involved in the effects induced by cohabitation with ETB mice and point towards β2-AR participation in the immune effects analyzed.

Aggressive differentiated thyroid cancer with multiple metastases and NRAS and TERT promoter mutations: A case report.

Oncol Lett. 2017 Aug;14(2):2186-2190

Abstract
Sorafenib, a tyrosine kinase inhibitor, is approved for the treatment of advanced differentiated thyroid carcinoma (DTC). Resistance to sorafenib may appear under treatment and may be associated with increased aggressiveness of the neoplasia. The present study reports the case of a 65-year-old male who underwent total thyroidectomy for a follicular thyroid carcinoma, Hürthle cell variant, in February 2005. Until January 2010, the patient received four consecutive (131)I doses (total dose, 612 mCi) for increased serum thyroglobulin (Tg) and initial faint lung uptake (which eventually became undetectable). Subsequently, the patient developed several sequential bone (humerus, rib and skull), adrenal and lung metastases, the majority of which were surgically removed. Histological examination in all cases revealed evidence of DTC metastases that were strongly positive for Tg, as revealed by immunohistochemistry. In March 2014, sorafenib therapy was initiated, but it was discontinued 10 months later to allow an undelayable prostatectomy. Immediately upon surgery, the patient developed a large metastatic lesion in the right gluteal muscle, whose biopsy revealed undifferentiated neoplasia of epithelial origin, and the patient succumbed shortly afterwards. An extensive comparative search for biochemical and molecular markers was performed on all available tissues (primary tumor, and differentiated and undifferentiated metastases). The primary tumor and all the available metastases exhibited the same molecular oncogenic markers (namely, the RAS mutation p.Q61R and the telomerase promoter mutation C228T). In addition, the undifferentiated metastasis exhibited a p53 mutation. The present study reports a case of a sudden acceleration of DTC metastatic progression following sorafenib discontinuation, which could have been due to the emergence of sorafenib-resistant undifferentiated p53-positive tumor cell clones.

A malignant pheochromocytoma in a child with von Hippel-Lindau mutation.

Clujul Med. 2017;90(3):356-358

Authors: Popa G, Blag CL, Bota M, Zolog A

Abstract
Pheochromocytoma is a rare neuroendocrine tumor that arises from the chromaffin cells of the sympathetic nervous system. Over one third of pheochromocytomas are associated with germline mutations. We describe a 3 year-old girl with an inherited right adrenal malignant pheochromocytoma, with the mother diagnosed with von Hippel-Lindau syndrome. Genetic tests revealed the presence of the VHL c 244 C>G (p. Arg 82 Gly) heterozygote mutation in the mother, as well as in the child. After 6 months from the complete resection of the tumor, the patient is without any clinical symptoms, with normal blood pressure, normal ophthalmoscopy, no tumor markers and no evidence of tumor on cerebral or abdominal MRI. Lifelong complex follow-up is needed, as it is known that at a later age VHL mutation may cause retinal angiomas, cerebellar and spinal hemangioblastomas, relapsed pheocromocytoma, pancreatic and renal cysts, clear cell renal cell carcinoma and endolymphatic sac tumors.

Abstract
We report the case of a 48-year old woman where probably the intramuscular administration of glucocorticoids by an orthopedist induced a pheochromocytoma crisis. The development of a cardiogenic shock with a cardiac arrest made the use of a venoarterial extra corporeal membrane oxygenation (VA-ECMO, Cardiohelp®, Maquet, Rastatt) necessary. To treat a pulmonary edema under VA-ECMO an Impella-CP® (Abiomed, Aachen) was implanted. A coronary angiography, endomyocardial biopsies and a computer tomography were performed. Finally a 7 cm × 5 cm tumor mass in the left adrenal medulla was detected. The blood values presented high levels of catecholamines. The total results of the examinations led us to the final diagnosis of a pheochromocytoma which was finally surgical removed.

Cardiovascular events in patients with mild autonomous cortisol secretion: analysis with artificial neural networks.

Eur J Endocrinol. 2017 Jul;177(1):73-83

Authors: Morelli V, Palmieri S, Lania A, Tresoldi A, Corbetta S, Cairoli E, Eller-Vainicher C, Arosio M, Copetti M, Grossi E, Chiodini I

Abstract
BACKGROUND: The independent role of mild autonomous cortisol secretion (ACS) in influencing the cardiovascular event (CVE) occurrence is a topic of interest. We investigated the role of mild ACS in the CVE occurrence in patients with adrenal incidentaloma (AI) by standard statistics and artificial neural networks (ANNs).
METHODS: We analyzed a retrospective record of 518 AI patients. Data regarding cortisol levels after 1 mg dexamethasone suppression (1 mg DST) and the presence of obesity (OB), hypertension (AH), type-2 diabetes (T2DM), dyslipidemia (DL), familial CVE history, smoking habit and CVE were collected.
RESULTS: The receiver-operating characteristic curve analysis suggested that 1 mg DST, at a cut-off of 1.8 µg/dL, had the best accuracy for detecting patients with increased CVE risk. In patients with 1 mg-DST ≥1.8 µg/dL (DST+, n = 223), age and prevalence of AH, T2DM, DL and CVE (66 years, 74.5, 25.9, 41.4 and 26.8% respectively) were higher than that of patients with 1 mg-DST ≤1.8 µg/dL (61.9 years, 60.7, 18.5, 32.9 and 10%, respectively, P < 0.05 for all). The CVE were associated with DST+ (OR: 2.46, 95% CI: 1.5-4.1, P = 0.01), regardless of T2DM, AH, DL, smoking habit, gender, observation period and age. The presence of at least two among AH, T2DM, DL and OB plus DST+ had 61.1% sensitivity in detecting patients with CVE. By using the variables selected by ANNs (familial CVE history, age, T2DM, AH, DL and DST+) 78.7% sensitivity was reached.
CONCLUSIONS: Cortisol after 1 mg-DST is independently associated with the CVE occurrence. The ANNs might help for assessing the CVE risk in AI patients.

Abstract
OBJECTIVES: To describe the characteristics, management, and outcome of patients admitted to ICUs for pheochromocytoma crisis.
DESIGN: A 16-year multicenter retrospective study.
SETTING: Fifteen university and nonuniversity ICUs in France.
PATIENTS: Patients admitted in ICU for pheochromocytoma crisis.
INTERVENTIONS: None.
MEASUREMENT AND MAIN RESULTS: We included 34 patients with a median age of 46 years (40-54 yr); 65% were males. At admission, the median Sequential Organ Failure Assessment score was 8 (4-12) and median Simplified Acute Physiology Score II 49.5 (27-70). The left ventricular ejection fraction was consistently decreased with a median value of 30% (15-40%). Mechanical ventilation was required in 23 patients, mainly because of congestive heart failure. Vasoactive drugs were used in 23 patients (68%) and renal replacement therapy in eight patients (24%). Extracorporeal membrane oxygenation was used as a rescue therapy in 14 patients (41%). Pheochromocytoma was diagnosed by CT in 33 of 34 patients. When assayed, urinary metanephrine and catecholamine levels were consistently elevated. Five patients underwent urgent surgery, including two during extracorporeal membrane oxygenation. Overall ICU mortality was 24% (8/34), and overall 90-day mortality was 27% (9/34). Crude 90-day mortality was not significantly different between patients managed with versus without extracorporeal membrane oxygenation (22% vs 30%) (p = 0.7) despite higher severity scores at admission in the extracorporeal membrane oxygenation group.
CONCLUSIONS: Mortality is high in pheochromocytoma crisis. Routinely considering this diagnosis and performing abdominal CT in patients with unexplained cardiogenic shock may allow an earlier diagnosis. Extracorporeal membrane oxygenation and adrenalectomy should be considered as a therapeutic in most severe cases.

GROWTH RATE OF PARAGANGLIOMAS RELATED TO GERMLINE MUTATIONS OF THE SDHX GENES.

Endocr Pract. 2017 Mar;23(3):342-352

Authors: Michałowska I, Ćwikła JB, Michalski W, Wyrwicz LS, Prejbisz A, Szperl M, Nieć D, Neumann HP, Januszewicz A, Pęczkowska M

Abstract
OBJECTIVE: The purpose was to determine the growth rate of succinate dehydrogenase subunit (SDHx) gene-related paragangliomas based on computed tomography (CT) measurements.
METHODS: Twenty-seven patients with SDHx mutations who underwent subsequent CT examinations were enrolled in the study. Tumors were classified as head and neck (HNP), thoracic, or abdominal/pelvic paragangliomas (PGLs). The percentage volume increase and volume doubling time were estimated.
RESULTS: We analyzed 56 PGLs (21 with SDHD, 6 with SDHB mutations) in 27 patients (16 men, 11 women; mean age 37.7 years). The estimated median of the follow-up was 23 months. Twenty-two (39.3%) PGLs were located in the abdomen, 8 (14.3%) in the thorax, and 26 (46.4%) in the head and neck region. The median volume growth rate was estimated at 10.4% per year (interquartile range [IQR]: -1.3; 36.3). The volume doubling time was estimated as 7.01 (2.24;+∞) years. By tumor site, the estimated medians of the annual volume growth rates were 13.6% (IQR:0.8 -30.4) for HNP, -6.06% (IQR: -1.79;47.32) for thoracic PGLs, and 10.5% (IQR: -2.2;44.6) for abdominal PGLs. The volume doubling time was 5.44 years (2.61; 87.0) for HNP, 11.8 years (1.79;+∞) for thoracic PGLs, and 6.94 years (1,88;+∞) for abdominal PGLs. There was no significant difference in the volume growth rate according to tumor location or initial size (P>.7 and P = .07, respectively) or gene mutation type (SDHB vs. SDHD, P>.8).
CONCLUSION: PGLs related to SDHx mutations are slowly growing tumors. There were no correlations between tumor location, growth rate or initial size over a 23-month follow-up period.
ABBREVIATIONS: CT = computed tomography HNP = head and neck paraganglioma IQR = interquartile range PGL = paraganglioma PPGL = pheochromocytoma and paraganglioma SDH = succinate dehydrogenase.

Authors: Cao F, Oba T, Saiura P, Li F

Abstract
Radical antegrade modular pancreatosplenectomy(RAMPS) has been applied more and more in clinical practice to improve the R0 resection rate in pancreatic body/tail adenocarcinoma.Comparing with traditional procedure, the resection plane in RAMPS is deeper with en-bloc resection of renal fascia, anterior renal fat capsule and even left adrenal gland and regional lymph nodes including No.7, 8, 9, 10, 11p, 11d, partial 14p/d, partial 16a2 and 18.Despite that RAMPS is in favor of improving R0 resection rate, there are many problems about this procedure unsolved and effect on patient survival is still awaited.

Clinical Score Predicting Long-Term Survival after Repeat Resection for Recurrent Adrenocortical Carcinoma.

J Am Coll Surg. 2016 Dec;223(6):794-803

Authors: Tran TB, Maithel SK, Pawlik TM, Wang TS, Hatzaras I, Phay JE, Fields RC, Weber SM, Sicklick JK, Yopp AC, Duh QY, Solorzano CC, Votanopoulos KI, Poultsides GA

Abstract
BACKGROUND: Adrenocortical carcinoma (ACC) is an aggressive malignancy typically resistant to chemotherapy and radiation. Surgery, even in the setting of locally recurrent or metastatic disease, remains the only potentially curative option. However, the subset of patients who will benefit from repeat resection in this setting remains ill defined. The objective of this study was to propose a prognostic clinical score that facilitates selection of patients for repeat resection of recurrent ACC.
STUDY DESIGN: Patients who underwent curative-intent repeat resection for recurrent ACC at 1 of 13 academic medical centers participating in the US ACC Study Group were identified. End points included morbidity, mortality, and overall survival.
RESULTS: Fifty-six patients underwent repeat curative-intent resection for recurrent ACC (representing 21% of 265 patients who underwent resection for primary ACC) from 1997 to 2014. Median age was 52 years. Sites of resected recurrence included locoregional only (54%), lung only (14%), liver only (12%), combined locoregional and lung (4%), combined liver and lung (4%), and other distant sites (12%). Thirty-day morbidity and mortality rates were 40% and 5.4%, respectively. Cox regression analysis revealed that the presence of multifocal recurrence, disease-free interval <12 months, and extrapulmonary distant metastases were independent predictors of poor survival. A clinical score consisting of 1-point each for the 3 variables demonstrated good discrimination in predicting survival after repeat resection (5-year: 72% for 0 points, 32% for 1 point, 0% for 2 or 3 points; p = 0.0006, area under the curve = 0.78).
CONCLUSIONS: Long-term survival after repeat resection for recurrent ACC is feasible when 2 of the following factors are present: solitary tumor, disease-free interval >12 months, and locoregional or pulmonary recurrence.

Abstract
The purpose of this study was to evaluate the DNA methylation levels of steroidogenic enzyme genes in aldosterone-producing adenoma (APA) and the effects of gene mutations in APA on the DNA methylation levels. DNA methylation array analysis was conducted using nonfunctioning adrenocortical adenoma (n=12) and APA (n=35) samples, including some with a KCNJ5 mutation (n=21), an ATP1A1 mutation (n=5), and without the known mutations (n=9). The quantitative polymerase chain reaction assay was performed for the detection of CYP11B2 and CYP11B1 expression levels in nonfunctioning adrenocortical adenoma and APA. We introduced the KCNJ5 T158A mutation using lentivirus delivery in the human adrenocortical 15 cell line, and analyzed the effects of the mutation on DNA methylation levels. We analyzed the 83 presumed DNA methylation sites of steroidogenic enzymes. In APA, we found 7 hypomethylated sites in CYP11B2 and 1 hypomethylated and 6 hypermethylated sites in CYP11B1 There were no differences in the steroidogenic enzymes gene DNA methylation of peripheral leukocytes between nonfunctioning adrenocortical adenoma and APA. No CYP11B2 methylation level was associated with CYP11B2 transcription levels in APA. All methylation sites, except for a CYP11B2 region, showed no difference among APAs with or without gene mutations. Human adrenocortical 15 cells with the KCNJ5 mutation showed no changes in CYP11B2 or CYP11B1 methylation levels compared with control cells. We demonstrated that CYP11B2 in APA was extensively hypomethylated, and CYP11B2 methylation in the region with hypomethylation was not induced by KCNJ5 or ATP1A1 mutations that cause aldosterone overproduction in APA and a KCNJ5 mutation human adrenocortical 15 cells.

Abstract
The association of pathological features of cortisol-producing adrenocortical adenomas (ACAs) with somatic driver mutations and their molecular classification remain unclear. In this study, we explored the association between steroidogenic acute regulatory protein (StAR) expression and the driver mutations activating cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) signaling to identify the pathological markers of ACAs. Immunohistochemical staining for StAR and mutations in the protein kinase cAMP-activated catalytic subunit alpha (PRKACA), protein kinase cAMP-dependent type I regulatory subunit alpha (PRKAR1A) and guanine nucleotide binding protein, alpha stimulating (GNAS) genes were examined in 97 ACAs. The association of StAR expression with the clinical and mutational features of the ACAs was analyzed. ACAs with mutations in PRKACA, GNAS, and PRKAR1A showed strong immunopositive staining for StAR. The concordance between high StAR expression and mutations activating cAMP/PKA signaling in the ACAs was 99.0%. ACAs with high expression of StAR had significantly smaller tumor volume (P < 0.001) and higher urinary cortisol per tumor volume (P = 0.032) than those with low expression of StAR. Our findings suggest that immunohistochemical staining for StAR is a reliable pathological approach for the diagnosis and classification of ACAs with cAMP/PKA signaling-activating mutations.

Are patients with hormonally functional phaeochromocytoma and paraganglioma initially receiving a proper adrenoceptor blockade? A retrospective cohort study.

Clin Endocrinol (Oxf). 2016 Jul;85(1):62-9

Abstract
OBJECTIVE: Pharmacological treatment is mandatory in patients with hormonally functional phaeochromocytoma and paraganglioma (PHAEO/PGL). We evaluated if patients initially diagnosed with hormonally functional PHAEO/PGL by various medical subspecialties received proper adrenoceptor blockade, and analysed factors predicting the prescription of adequate treatment.
METHODS: In a retrospective cohort study, we reviewed data from patients initially diagnosed with hormonally functional PHAEO/PGL outside the National Institutes of Health and Cedars-Sinai Medical Center, who were referred to these institutions between January 2001 and April 2015. Logistic regression was used to assess factors associated with proper adrenoceptor blockade.
RESULTS: A total of 381 patients were included. Adequate pharmacological treatment was prescribed to 69·3%, of which 93·1% received α-adrenoceptor blockers. Regarding patients who were inappropriately treated, 53% did not receive any medication. Independent predictors of the prescription of a proper blockade were the diagnosis by endocrinologists [odds ratio (OR) 4·14; 95% confidence interval (CI), 2·51-6·85; P < 0·001], the presence of high blood pressure (OR 5·94; 95% CI, 3·11-11·33; P < 0·001) and the evidence of metastasis (OR 5·96; 95% CI, 1·93-18·46; P = 0·002).
CONCLUSIONS: Although most patients received adequate pharmacological treatment, almost one-third were either not treated or received inappropriate medications. The diagnosis by endocrinologists, the presence of high blood pressure and the evidence of metastatic disease were identified as independent predictors of a proper blockade. These results highlight the need to educate physicians about the importance of starting adequate adrenoceptor blockade in all patients with hormonally functional PHAEO/PGL.
