Abstract
Few studies demonstrated a percentage decrease in the estimated glomerular filtration rate (eGFR) at a single time and the rate of hypoaldosteronism after adrenalectomy for primary aldosteronism (PA). Our aim was to investigate the evolution of renal function and the hypoaldosteronism risk after adrenalectomy for PA. Aldosterone, renin, eGFR, and electrolyte levels were determined before and at 1 week, 1, 3 and 6 months after unilateral adrenalectomy in 94 PA patients (40 men and 54 women). The main outcome was the postoperative eGFR decline using analysis of covariance with the preoperative eGFR as a covariate. eGFR decreased during first postoperative week compared to 3 months before surgery. During the first 6 months, eGFR remained stable at similar levels to the first week after surgery. Age (p=0.001), aldosterone levels (p=0.021) and eGFR 3 months before surgery (p+<+0.0001) had a significant correlation with eGFR during first postoperative week. High aldosterone levels at diagnosis were correlated with decline in renal function in the univariate model (p=0.033). In the multivariate analysis, aldosterone levels at diagnosis had a tendency to be an independent predictor of renal function after surgery (p=0.059). Postoperative biochemical hypoaldosteronism was diagnosed in 48% of the cases after adrenalectomy, but prolonged hyperkalemia occurred in only 4 cases (4.5%). Our findings showed a decrease of eGFR after unilateral adrenalectomy for PA. Additionally, aldosterone levels at diagnosis correlated with postoperative renal function. Postoperative biochemical hypoaldosteronism occurred in almost half of the patients, but prolonged hyperkalemia with fludrocortisone replacement was less frequent.

Abstract
BACKGROUND Neural tube defects (NTDs) are caused by genetic and environmental factors. ARMC5 is part of a novel ubiquitin ligase specific for POLR2A, the largest subunit of RNA polymerase II (Pol II). RESULTS We find that ARMC5 knockout mice have increased incidence of NTDs, such as spina bifida and exencephaly. Surprisingly, the absence of ARMC5 causes the accumulation of not only POLR2A but also most of the other 11 Pol II subunits, indicating that the degradation of the whole Pol II complex is compromised. The enlarged Pol II pool does not lead to generalized Pol II stalling or a generalized decrease in mRNA transcription. In neural progenitor cells, ARMC5 knockout only dysregulates 106 genes, some of which are known to be involved in neural tube development. FOLH1, critical in folate uptake and hence neural tube development, is downregulated in the knockout intestine. We also identify nine deleterious mutations in the ARMC5 gene in 511 patients with myelomeningocele, a severe form of spina bifida. These mutations impair the interaction between ARMC5 and Pol II and reduce Pol II ubiquitination. CONCLUSIONS Mutations in ARMC5 increase the risk of NTDs in mice and humans. ARMC5 is part of an E3 controlling the degradation of all 12 subunits of Pol II under physiological conditions. The Pol II pool size might have effects on NTD pathogenesis, and some of the effects might be via the downregulation of FOLH1. Additional mechanistic work is needed to establish the causal effect of the findings on NTD pathogenesis.

Abstract
BACKGROUND Adjuvant treatment with mitotane is commonly used after resection of adrenocortical carcinoma; however, treatment remains controversial, particularly if risk of recurrence is not high. We aimed to assess the efficacy and safety of adjuvant mitotane compared with surveillance alone following complete tumour resection in patients with adrenocortical carcinoma considered to be at low to intermediate risk of recurrence. METHODS ADIUVO was a multicentre, open-label, parallel, randomised, phase 3 trial done in 23 centres across seven countries. Patients aged 18 years or older with adrenocortical carcinoma and low to intermediate risk of recurrence (R0, stage I-III, and Ki67 ≤10%) were randomly assigned to adjuvant oral mitotane two or three times daily (the dose was adjusted by the local investigator with the target of reaching and maintaining plasma mitotane concentrations of 14-20 mg/L) for 2 years or surveillance alone. All consecutive patients at 14 study centres fulfilling the eligibility criteria of the ADIUVO trial who refused randomisation and agreed on data collection via the European Network for the Study of Adrenal Tumors adrenocortical carcinoma registry were included prospectively in the ADIUVO Observational study. The primary endpoint was recurrence-free survival, defined as the time from randomisation to the first radiological evidence of recurrence or death from any cause (whichever occurred first), assessed in all randomly assigned patients by intention to treat. Overall survival, defined as time from the date of randomisation to the date of death from any cause, was a secondary endpoint analysed by intention to treat in all randomly assigned patients. Safety was assessed in all patients who adhered to the assigned regimen, which was defined by taking at least one tablet of mitotane in the mitotane group and no mitotane at all in the surveillance group. The ADIUVO trial is registered with ClinicalTrials.gov, NCT00777244, and is now complete. FINDINGS Between Oct 23, 2008, and Dec 27, 2018, 45 patients were randomly assigned to mitotane and 46 to surveillance alone. Because the study was discontinued prematurely, 5-year recurrence-free and overall survival are reported instead of recurrence-free and overall survival as defined in the protocol. 5-year recurrence-free survival was 79% (95% CI 67-94) in the mitotane group and 75% (63-90) in the surveillance group (hazard ratio 0·74 [95% CI 0·30-1·85]). Two people in the mitotane group and five people in the surveillance group died, and 5-year overall survival was not significantly different (95% [95% CI 89-100] in the mitotane group and 86% [74-100] in the surveillance group). All 42 patients who received mitotane had adverse events, and eight (19%) discontinued treatment. There were no grade 4 adverse events or treatment-related deaths. INTERPRETATION Adjuvant mitotane might not be indicated in patients with low-grade, localised adrenocortical carcinoma considering the relatively good prognosis of these patients, and no significant improvement in recurrence-free survival and treatment-associated toxicity in the mitotane group. However, the study was discontinued prematurely due to slow recruitment and cannot rule out an efficacy of treatment.

Abstract
Adrenocortical carcinoma (ACC) is a rare cancer in which tissue-specific differentiation is paradoxically associated with dismal outcomes. The differentiated ACC subtype CIMP-high is prevalent, incurable, and routinely fatal. CIMP-high ACC possess abnormal DNA methylation and frequent β-catenin-activating mutations. Here, we demonstrated that ACC differentiation is maintained by a balance between nuclear, tissue-specific β-catenin-containing complexes, and the epigenome. On chromatin, β-catenin bound master adrenal transcription factor SF1 and hijacked the adrenocortical super-enhancer landscape to maintain differentiation in CIMP-high ACC; off chromatin, β-catenin bound histone methyltransferase EZH2. SF1/β-catenin and EZH2/β-catenin complexes present in normal adrenals persisted through all phases of ACC evolution. Pharmacologic EZH2 inhibition in CIMP-high ACC expelled SF1/β-catenin from chromatin and favored EZH2/β-catenin assembly, erasing differentiation and restraining cancer growth in vitro and in vivo. These studies illustrate how tissue-specific programs shape oncogene selection, surreptitiously encoding targetable therapeutic vulnerabilities. SIGNIFICANCE Oncogenic β-catenin can use tissue-specific partners to regulate cellular differentiation programs that can be reversed by epigenetic therapies, identifying epigenetic control of differentiation as a viable target for β-catenin-driven cancers.

Abstract
BACKGROUND Leiomyosarcoma is a rare malignant tumor of smooth muscle origin and represents 10-20% of all soft tissue sarcomas. Primary colon and rectal sarcomas constitute < 0.1% of all large bowel malignancies. In Li-Fraumeni syndrome, sarcomas are the second most frequent cancer (25%). Li-Fraumeni syndrome is a genetic disease with a familial predisposition to multiple malignant neoplasms. This syndrome has an autosomal dominant pattern of inheritance and high penetrance characterized by germline TP53 mutations. Patients with a history of cancer who do not meet all the "classic" criteria for Li-Fraumeni syndrome are considered to have Li-Fraumeni-like syndrome. To the best of our knowledge, this article is the first report of a patient with rectal leiomyosarcoma as the initial phenotypic manifestation of Li-Fraumeni-like syndrome. The authors also present a literature review. CASE PRESENTATION A 67-year-old Brazilian woman underwent anterior rectosigmoidectomy and panhysterectomy secondary to rectal leiomyosarcoma. She subsequently developed carcinomatosis and died 2 years after the operation. Her family medical history consisted of a daughter who died at 32 years of age from breast cancer, a granddaughter diagnosed with adrenocortical carcinoma at 6 years of age and two siblings who died from prostate cancer. A genetic study was carried out to identify a pathogenic variant of Li-Fraumeni syndrome. In the DNA extracted from the peripheral blood leukocyte, restriction fragment length polymorphism was analyzed to search for mutations in the TP53 gene. The DNA sequencing identified the germline pathogenic variant p. R337H heterozygous in exon 10 of TP53. The patient was classified as having Li-Fraumeni-like syndrome. CONCLUSION In patients with rectal leiomyosarcoma, it is advisable to investigate the family history of cancer and perform genetic studies to screen for Li-Fraumeni syndrome.

Abstract
PURPOSE Pregnancy is associated with the activation of the hypothalamus-pituitary-adrenal axis, which can cause a misdiagnosis of Cushing's syndrome. The aim of this study is to evaluate the impact of pregnancy after pituitary surgery on the recurrence rate in Cushing's disease (CD) patients. METHODS This was a retrospective study in a tertiary center. Between 1990 and 2020, 355 CD patients underwent pituitary surgery. Of those, we included 113 female patients who were ≤ 45 years old (median age of 32 years, 14-45), PS remission, a follow-up of ≥6 months (median of 122 months, 6-402) and an available obstetric history. Recurrence was defined as the diagnosis of Cushing's syndrome via at least two altered first-line methods. The patients were divided into two subgroups according to pregnancy: no pregnancy or pregnancy prior to CD diagnosis (NP/PP) and pregnancy after CD pituitary surgery (PA). RESULTS Overall, recurrence occurred in 43 out of 113 patients (38%). A higher recurrence rate was seen in the PA subgroup (11/22, 50%), but there was no significant difference between the NP/PP subgroup (32/91, 35%). No difference in survival-free recurrence (SFR) was found between NP/PP and PA subgroups. The lower SFR was related to a higher PS plasma ACTH and normal pituitary at pathological analyses. CONCLUSIONS There was no difference in the recurrence rate in patients according to pregnancy history. Other studies with higher numbers of patients are needed to confirm these data.

Abstract
Primary macronodular adrenal hyperplasia (PMAH) is considered a rare cause of adrenal Cushing syndrome, is pituitary ACTH-independent, generally results from bilateral adrenal macronodules (>1 cm), and is often associated with variable cortisol secretion, resulting in a heterogeneous clinical presentation. Recent advances in the molecular pathogenesis of PMAH have offered new insights into the comprehension of this heterogeneous and complex adrenal disorder. Different molecular mechanisms involving the actors of the cAMP/protein kinase A pathway have been implicated in the development of PMAH, including germline and/or somatic molecular defects such as hyperexpression of the G-protein aberrant receptors and pathogenic variants of MC2R, GNAS, PRKAR1A, and PDE11A. Nevertheless, since 2013, the ARMC5 gene is believed to be a major genetic cause of PMAH, accounting for more than 80% of the familial forms of PMAH and 30% of apparently sporadic cases, except in food-dependent Cushing syndrome in which ARMC5 is not involved. Recently, 2 independent groups have identified that the tumor suppressor gene KDM1A is responsible for PMAH associated specifically with food-dependent Cushing syndrome. Consequently, PMAH has been more frequently genetically associated than previously assumed. This review summarizes the most important aspects, including hormone secretion, clinical presentation, radiological imaging, and molecular mechanisms, involved in familial Cushing syndrome associated with PMAH.

Abstract
1 Background: The ESE-ENSAT guidelines on ACC management suggest adjuvant mitotane for patients at high risk of recurrence. This indication has limited evidence base, lacking results from randomized controlled trials. No suggestion for or against adjuvant mitotane in low-risk patients was given, since studies did not stratify patients for prognosis. The randomized controlled study ADIUVO compared the efficacy of adjuvant mitotane treatment vs. observation in prolonging recurrence-free survival (RFS) in patients at low-intermediate risk of recurrence. Methods: The main inclusion criteria were: stage I-III ACC, R0 surgery, and Ki-67 ≤10%. Patients were randomly assigned 1:1 to adjuvant mitotane or observation. The primary endpoint of the study was RFS. Patients who refused randomization were eligible for the ADIUVO OBSERVATIONAL study. In this prospective, observational study, patients were managed as in ADIUVO except for randomization. A total of 91 patients were enrolled in ADIUVO, 45 in the mitotane and 46 in the observation arm. Baseline characteristics of patients were perfectly matched between the 2 arms: median age, 51 vs. 50.5 years; female, 73% vs. 67%; stage I, 20% vs. 26%; stage II, 67% vs. 63%, stage III, 13% vs. 11%; ACC secretion 44% vs. 36%; Weiss 5 vs. 5; respectively. In ADIUVO OBSERVATIONAL, 42 patients were treated with mitotane and 53 were untreated. Baseline characteristics of patients were matched between the 2 groups and with mitotane and observation groups in ADIUVO. Thus, the ADIUVO OBSERVATIONAL cohort was analyzed in parallel to deal with the lower than expected recruitment in ADIUVO. Results: In the ADIUVO study, recurrences were 8 in the MIT and 11 in the OBS arm, while deaths were 2 and 5, respectively. RFS and overall survival (OS) did not significantly differ between the 2 arms. In the OBS arm, the HR for recurrence was 1.321 (95%CI, 0.55-3.32, p = 0.54) and HR for death 2.171 (95%CI, 0.52-12.12, p = 0.29). The survival analysis in the ADIUVO OBSERVATIONAL study confirmed that of ADIUVO. Given the outcome of both studies, the NNT is 55. Conclusions: ACC patients at low-intermediate risk of recurrence after surgery are a minority; however, they show a far better prognosis than expected (5-yr RFS is 75%) and do not benefit significantly from adjuvant mitotane. The results of the ADIUVO study do not support routine use of adjuvant mitotane in this subset of patients, who may thus avoid a potentially toxic treatment. This is an important step toward personalization of ACC care. Clinical trial information: NCT00777244.

Abstract
OBJECTIVE Adrenocortical carcinoma (ACC) has an aggressive but variable clinical course. Prognostic stratification based on the European Network for the Study of Adrenal Tumours stage and Ki67 index is limited. We aimed to demonstrate the prognostic role of a points-based score (S-GRAS) in a large cohort of patients with ACC. DESIGN This is a multicentre, retrospective study on ACC patients who underwent adrenalectomy. METHODS The S-GRAS score was calculated as a sum of the following points: tumour stage (1-2 = 0; 3 = 1; 4 = 2), grade (Ki67 index 0-9% = 0; 10-19% = 1; ≥20% = 2 points), resection status (R0 = 0; RX = 1; R1 = 2; R2 = 3), age (<50 years = 0; ≥50 years = 1), symptoms (no = 0; yes = 1), and categorised, generating four groups (0-1, 2-3, 4-5, and 6-9). Endpoints were progression-free survival (PFS) and disease-specific survival (DSS). The discriminative performance of S-GRAS and its components was tested by Harrell's Concordance index (C-index) and Royston-Sauerbrei's R2D statistic. RESULTS We included 942 ACC patients. The S-GRAS score showed superior prognostic performance for both PFS and DSS, with best discrimination obtained using the individual scores (0-9) (C-index = 0.73, R2D = 0.30, and C-index = 0.79, R2D = 0.45, respectively, all P < 0.01vs each component). The superiority of S-GRAS score remained when comparing patients treated or not with adjuvant mitotane (n = 481 vs 314). In particular, the risk of recurrence was significantly reduced as a result of adjuvant mitotane only in patients with S-GRAS 4-5. CONCLUSION The prognostic performance of S-GRAS is superior to tumour stage and Ki67 in operated ACC patients, independently from adjuvant mitotane. S-GRAS score provides a new important guide for personalised management of ACC (i.e. radiological surveillance and adjuvant treatment).

Abstract
OBJECTIVE The cyclicity (CIC) of cortisol spontaneously occurs in a minority of patients with Cushing syndrome (CS). When it arises, diagnostic and therapeutic approaches become more challenging. This study aimed to report a patient with Cushing disease (CD) who achieved normalization of cortisol and CIC pattern with pasireotide long-acting release (pasi/LAR). METHODS A 43-year-old female patient related an 8-month history of CS. An 8-mm pituitary nodule depicted by magnetic resonance imaging, serum cortisol suppression of >50% after 8 mg of dexamethasone therapy, and the absence of other lesions were compatible with a CD diagnosis. The patient presented with a CIC pattern with 1 episode before and 17 episodes after an unsuccessful pituitary surgery. RESULTS Medical treatment with cabergoline alone up to 3.5 mg/wk and a combined treatment with ketoconazole 400 mg/d did not improve CIC CS. Pasi/LAR was initiated at a dose of 20 mg/mo. A few days after the first dose, the patient experienced symptoms suggestive of adrenal insufficiency. The medication and dose were maintained for 24 months. During this period, there was a normalization of UFC levels and progressive clinical improvement. Additionally, new episodes of CIC were not observed. CONCLUSION A CD patient with a challenging issue of CIC was reported. The condition was not controlled after pituitary surgery and by the combined treatment with cabergoline and ketoconazole, although hypercortisolism was abated by the continuous use of pasi/LAR. To our knowledge, this is the first report as regards the use of this medication to control CIC in a patient with CD.

Abstract
Abstract
Adrenocortical carcinoma (ACC) is a rare malignant neoplasia that is usually associated with a dismal prognosis. ACC overall survival (OS) depends on the particular biology of the tumor. Pan-genomic studies have demonstrated the involvement of ATRX and ZNRF3 genes in adrenocortical tumorigenesis. Aim: To evaluate ATRX and ZNRF3 protein expression in a large cohort of adults with ACC followed at a single tertiary referral center to establish the prognostic value of these genes. Methods: Two pathologists analyzed immunohistochemically-stained slides for ATRX and ZNRF3 (blinded assessment) proteins using tissue microarrays comprising tissue samples from 82 ACC (kappa 0.854; P<0.001). Cohort: female 76.8%; median age 38.2 (15.3–85.4) years; 67.5% of patients presented with hypercortisolism; ENSAT stage 1, 11.12%; 2, 44.44%; 3 and 4: (44.44%). The median follow-up time was 39.58 (1.4–406.8) months; 39 patients died during this period. Low protein expression was defined as follows: ATRX, when < 25% of tumor cells were immunoreacted; ZNRF3, when a score < 3 (extension + intensity) was established. Results: Low ATRX protein expression was positively associated with the age at diagnosis (P< 0.001), and it was negatively correlated with tumor size (P=0.020) and with Weiss score (P=0.033). Low ZNRF3 protein expression correlated negatively with tumor weight (P=0.026), with tumor size (P= 0.005), and with Weiss score (P=0.002). Regarding OS, the low protein expression of ATRX and ZNRF3 was associated with a decrease of OS (P=0.045 and P=0.012, respectively). The Cox model for ATRX protein expression showed a HR of 0.521 (95% CI 0.273–0.997; P=0.049); for ZNRF3 expression, HR = 0.441 (95% CI 0.229–0.852; P=0.015). The combined protein expression of both genes was also associated with a decrease in OS in this cohort (P=0.02). The high ATRX and ZNRF3 protein expressions were positively associated with optimistic recurrence-free survival (P=0.027, P=0.005, respectively). Conclusion: The knowledge of tumor biology is an important step to deliver personalized medicine, affording the opportunity to design better clinical approaches and targeted therapies. This study brought pan-genomic studies closer to clinical practice with an easily accessible tool for stratifying patients with ACC. We demonstrated that low levels of protein expression of ATRX and ZNRF3 are negative prognostic markers of ACC.

Abstract
Background: The ESE-ENSAT guidelines on the management of adrenocortical carcinoma (ACC) suggest adjuvant mitotane for patients at high risk of recurrence following radical surgery. This indication has a limited evidence base, lacking results from randomized controlled trials. No suggestion for or against adjuvant mitotane in low-risk patients was given, since studies did not stratify patients for prognosis. The randomized controlled study ADIUVO compared the efficacy of adjuvant mitotane treatment vs. observation in prolonging recurrence-free survival (RFS) in ACC patients at low-intermediate risk of recurrence. Methods: The main inclusion criteria were: stage I-III ACC, R0 surgery, and Ki-67 ≤10%. Patients were randomly assigned 1:1 to adjuvant mitotane (MIT) or observation (OBS). The primary endpoint of the study was RFS. Patients who refused randomization were offered inclusion in the ADIUVO OBSERVATIONAL study. In this prospective, observational study, patients were managed as in the ADIUVO study. A total of 91 patients were enrolled in ADIUVO, 45 in the MIT and 46 in the OBS arm. Baseline characteristics of patients were perfectly matched between the 2 arms: median age, 51 vs. 50.5 years; female, 73% vs. 67%; stage I, 20% vs. 26%; stage II, 67% vs. 63%, stage III, 13% vs. 11%; ACC secretion 44% vs. 36%; Weiss 5 vs. 5; respectively. In ADIUVO OBSERVATIONAL, 42 patients were treated with mitotane and 53 were untreated. Baseline characteristics of patients were matched between the 2 groups and with MIT and OBS groups in ADIUVO. Thus, the ADIUVO OBSERVATIONAL cohorts could be analyzed in parallel to those of ADIUVO. Results: In the ADIUVO study, recurrences were 8 in the MIT and 11 in the OBS arm, while deaths were 2 and 5, respectively. RFS and overall survival (OS) did not significantly differ between the 2 arms. Tumor size was a predictor of RFS in multivariable analysis. In the OBS arm, the HR for recurrence was 1.321 (95%CI, 0.55–3.32, p=0.54) and HR for death 2.171 (95%CI, 0.52–12.12, p=0.29). The survival analysis in the ADIUVO OBSERVATIONAL study confirmed the findings of ADIUVO. Given the outcome of both studies, the NNT is 55. Conclusions: ACC patients at low-intermediate risk of recurrence after surgery are a minority; however, they show a far better prognosis than expected (5-year RFS is about 75%) and do not benefit significantly from adjuvant mitotane. The results of the ADIUVO study do not support routine use of adjuvant mitotane in this subset of patients, who may thus avoid a potentially toxic treatment. This is an important step toward personalization of ACC care.

Abstract
The risk of radiotherapy-induced malignancies (RIMs) is a concern when treating Li-Fraumeni syndrome (LFS) or Li-Fraumeni Like (LFL) patients. However, the type of TP53 pathogenic germline variant may possibly influence this risk. TP53 p.R337H mutation is particularly prevalent in Brazil. We aimed to evaluate the outcomes of patients with pathogenic TP53 variants treated for localized breast cancer in a Brazilian cohort. We evaluated retrospectively a cohort of patients with germline TP53 pathogenic variants treated for localized breast cancer between December 1999 and October 2017. All patients were followed by the Hereditary Cancer Group of an academic cancer center. Our primary objective was to evaluate the occurrence of RIMs after adjuvant radiotherapy. Sixteen patients were evaluated; 10 (62.5%) had a germline TP53 p.R337H pathogenic variant. Median age was 39.8 years. Thirteen patients had invasive ductal carcinoma: 8 (61.5%) were hormone receptor-positive; 6 (46.1%), human epithelial growth factor receptor 2 (HER2)-amplified. Three patients had ductal carcinoma in situ. Most patients (N = 12/16, 75%) received adjuvant radiotherapy. After a median follow-up of 52.5 months, 2 patients (2/12, 16.6%) had RIMs. One had a fibrosarcoma and the other, a low-grade leiomyosarcoma. In the group treated with radiotherapy, one distant recurrence was diagnosed (1/12), and no loco-regional recurrence occurred. Among 4 patients who did not receive radiotherapy, 2 presented with loco-regional recurrence. In this cohort of patients with LFS enriched in TP53 p.R337H pathogenic variant, the incidence of RIMs after treatment of localized breast cancer was lower than previous literature. Nevertheless, rates of RIMs were still alarming. Early molecular diagnosis and careful evaluation of treatment risks and benefits are essential for these patients.

Abstract
3-Hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR) is the rate-limiting enzyme of the mevalonate pathway, which generates cholesterol and non-sterol compounds such as isoprenoid, which are involved in key steps of tumorigenesis such as cell growth and proliferation. Our aim was to evaluate the role of the mevalonate pathway in adrenocortical tumors (ACTs). Expression pattern of HMGCR, FDFT1, LDLR, SCARB1, StAR, TSPO, CYP11A1, CYP11B1, CYP17A1, CYP21A1, and HSD3B1 genes, involved in the mevalonate pathway and steroidogenesis, was quantified by real-time RT-PCR in 46 ACT [14 adenomas (ACA) and 11 carcinomas (ACC) from adults and 13 ACA and 8 ACC from pediatric patients]. Effects of the mevalonate pathway inhibition on NCI-H295A cell viability was assessed by colorimetric assay. HMGCR was overexpressed in most adult ACT. The expression of TSPO, STAR, CYP11B1, CYP21A1, and HSD3B1 in adult ACC was significantly lower than in ACA (p<0.05). Regarding pediatric ACT, the expression of genes involved in steroidogenesis was not different between ACA and ACC. Inhibition of isoprenoid production significantly decreased the viability of NCI-H295A cells (p<0.05). However, cholesterol synthesis blockage did not show the same effect on cell viability. Low expression of TSPO ,: StAR, CYP11B1, CYP21A1, and HSD3B1 characterized a signature of adult ACCs. Our data suggest that HMGCR overexpression in adult ACC might lead to intracellular isoprenoid accumulation and cell proliferation. Therefore, the mevalonate pathway is a potential target for ACC treatment.

Abstract
PURPOSE To analyze the bilateral and simultaneous petrosal sinus sampling (BIPSS) in a subgroup of children and adolescents with ACTH-dependent Cushing's syndrome (ADCS) METHODS: Retrospective study in a tertiary reference center. From 1993 and 2017, 19 children and adolescents (PED) were submitted to the BIPSS, median age of 14 years (range 9-19 years), 53% were males, 18 had Cushing's disease (CD) and one had ectopic ACTH syndrome (EAS). All procedures were performed with 10 µg of intravenous desmopressin. RESULTS The catheter positioning was successful in all cases. The central ACTH gradient was met in 17/19 cases. At baseline, central gradient occurred in 16/19 (84%) with gradient values of 7.2 ± 6.0. After stimulation, there was an increase in the center-periphery gradient values (33.6 ± 44.3). In one case, central gradient was defined only after stimulation. Two cases presented without a central gradient; one case of CD with a false-negative and one EAS case. Lateralization occurred in all cases with a central gradient. Confirmation of the tumor location presumed by the procedure with the surgical description occurred in 60% of the cases. The BIPSS in this PED subgroup of ADCS presented a sensitivity of 94.4% and specificity of 100%. There were no complications of the procedure. CONCLUSION In a series of children and adolescents with ADCS, BIPSS was safe and highly accurate in defining the central to peripheral ACTH gradient using desmopressin as secretagogue. Nevertheless, there was a limited value of the ACTH-gradient between the petrosal sinuses for the tumor location.

Abstract
Objective To analyze the morphological and functional characteristics of primary macronodular adrenal hyperplasia (PMAH) nodules carrying or not carrying ARMC5 mutations and the consequences of the presence of mutations in terms of the pattern of macronodule composition and functional state. Subjects and methods The analyses were performed by hematoxylin-eosin staining, immunohistochemistry, microdissection of spongiocyte tissue and RT-qPCR of histological sections from 16 patients diagnosed with PMAH with germline (5) or germline/somatic mutations (5) and without mutations (6) in the ARMC5 gene. Results Hyperplastic nodules were predominantly composed of spongiocytes in mutated and nonmutated sections. ARMC5 mRNA expression in spongiocytes was higher in ARMC5-mutated nodules than in ARMC5-nonmutated nodules, and homogenous ARMC5 protein distribution was observed. The presence of arginine-vasopressin receptor (AVP1AR) and ectopic ACTH production were observed in both cell populations regardless of ARMC5 mutations; the numbers of serotonin receptor (5HT4R)- and proliferating cell nuclear antigen (PCNA)-positive cells were higher in macronodules carrying ARMC5 mutations than in those without mutations. Conclusions Our results suggest that the presence of ARMC5 mutations does not interfere with the pattern of distribution of spongiocytes and compact cells or with the presence of AVP1AR, gastric-inhibitory polypeptide receptor (GIPR) and ectopic ACTH. Nevertheless, the higher numbers of PCNA-positive cells in mutated nodules than in nonmutated nodules suggest that mutated ARMC5 can be related to higher proliferation rates in these cells. In conclusion, our results provide more information about the crosstalk among abnormal GPCRs, ectopic ACTH in steroidogenesis and the ARMC5 gene, which may be relevant in understanding the pathogenesis and diagnosis of patients with PMAH.

Abstract
Purpose This prospective study presents the results of a new approach in the treatment of primary macronodular adrenal hyperplasia (PMAH), with simultaneous total adrenalectomy of the larger adrenal gland and partial adrenalectomy of the contralateral adrenal gland (adrenal-sparing surgery). Materials and Methods We performed a prospective study including 17 patients with PMAH treated surgically with adrenal-sparing surgery in a tertiary referral hospital, with a median follow-up of 41 months. Clinical, hormonal, and genetic parameters were evaluated before surgery and during follow-up. All patients had at least 1 radiological examination before and after the procedure. Results Among the 17 patients, all but 1 patient had complete hypercortisolism control, and 12 recovered normal adrenal function after surgery. Significant improvement in clinical parameters was observed: weight loss (P = .004); reduction of both systolic (P = .001) and diastolic (P = .001) blood pressure; and reduction in the number of antihypertensive drugs (P < .001). Intra-, peri-, and postoperative complications were not observed. Conclusion Adrenal-sparing surgery is a safe and feasible procedure to treat patients with PMAH, providing a substantial chance of hypercortisolism control without the disadvantages of lifetime corticosteroid replacement.

Abstract
BACKGROUND: Dopaminergic agonist cabergoline (CAB) has been used in pharmacological treatment of Cushing’s disease (CD). The effect is attributed to the frequent expression of subtype 2 dopamine receptor in corticotropic tumors. However, in vivo studies demonstrated normalization of urinary cortisol (UC) in about 30-40% of cases over the long term, mainly after surgical failure. Objective: To evaluate the effect of CAB as monotherapy in early preoperative period and on recurrence of Cushing’s disease. Methods. A single-center retrospective study was conducted in a tertiary referral center. Twenty-one patients with confirmed CD were included. Median age was 32 years (13-70), 86% female, 10 with microadenomas, 11 with macroadenomas. They were diagnosed from 1986 to 2016 and used CAB as monotherapy either in the preoperative period (n=7, CABi) or in recurrence, before any other treatment (n=14, CABr). It was considered ‘complete response’ a 24h-UC normalization and ‘partial response’ a 24h-UC reduction >50%. UC was obtained on the last follow-up evaluation. Normalization of nocturnal salivary cortisol (NSC) on CAB was evaluated in most cases, as well as the larger tumor diameter by pituitary MRI, before and after CAB treatment. Results: Complete response was achieved in 29% (6/21) of subjects after 14.9±16.4 months of treatment with a mean dose of 2.2±1.0 mg/wweek. Partial response occurred in 9.5% (2/21). NSC normalized in 35% (6/17) and no variation in tumor diameter before and after CAB use was observed (n=13): 6.8±6.8 vs. 7.2±7.1 mm, respectively. There was no normalization of UC in CABi at the end of the treatment whereas in CABr, 43% (6/14) of patients reached complete response. CABi group was treated for 4.7±1.9 months and CABr was treated for 20.1±18.1 months. Both groups were on similar doses of CAB (CABi 2.1±0.9 and CABr 2.3±1.1 mg/w). Interestingly, the difference between the groups’ complete response was evident early on 3 months of treatment: no cases in CABi vs. 60% (6/10) in CABr (p=0.035) despite a lower dose in CABr (1.0 vs. 1.5; p=0.008). Normalization of NSC occurred in 20% in CABi and 42% in CABr. Conclusion. Normalization of UC and NSC occurred in about 30% of total patients, mainly those who used CAB on recurrence of CD. Due to the small number of subjects in CABi group, the absence of hormone control in this group requires further investigation in order to verify the effectiveness of CAB as primary therapy or as preoperative treatment option.

Abstract
Background: Hypermineralocorticism (hypertension, hypokalemia, and low plasma renin activity) due to deoxycorticosterone (DOC) excess associated with adrenocortical carcinoma is extremely rare. DOC-producing tumors cause primary aldosteronism-like symptoms presenting low plasma aldosterone with very high DOC levels, and due to weak hormonal DOC activity, its diagnostic is done lately. Generally, malignant cases are progressive with a dismal prognosis. Clinical case: A 61-year-old woman was admitted to our hospital presenting lumbar pain and weight loss of 8 kg, in 2018. Previously, arterial hypertension was diagnosed in 2015, showing a satisfactory control with two classes of antihypertensive drugs. Physical exam: The patient presented no features of Cushing syndrome, but a palpable abdominal mass was noticed in the right flank. Blood pressure was 160x100 mmHg, with sustained high levels, despite regular treatment. Laboratory data: a hypokalemia (K 2.4 mEq/L, nr 3.5 -5.0 mEq/L) and hypernatremia (Na 146 mEq/L, nr 135 to 145 mEq/L), with metabolic alkalosis (venous pH 7.46 and serum bicarbonate 32 mmol/L, nr 23-27 mmol/L) was confirmed. Hormonal tests excluded hypercortisolism and pheocromocytoma. Serum aldosterone and renin were suppressed. Mineralocorticoid precursors dosage was extremely high, DOC (654 ng/dL, nr < 25 ng/dL) and progesterone (5.0 ng/mL, nr <0.89 ng/mL), as well 11-deoxycortisol (7.2 ng/mL, nr <0.5 ng/mL). Radiological imaging: abdominal CT showed a heterogeneous hypervascular adrenal mass (13.0x13.0x21.0 cm) exhibiting central necrosis, suggesting malignancy. FDG-PET/CT scan showed a hypermetabolic adrenal mass (SUVmax=13.8). Also, two metabolically active pulmonary nodules (SUVmax=3.7) measuring 0.7 and 0.4 cm were detected. The patient underwent right adrenalectomy, and the tumor was removed (24x13x13 cm). According to Weiss criteria (8/9) and modified Weiss criteria (5/7), the tumor was considered an adrenocortical carcinoma. Immunohistochemistry revealed a low Ki-67 index (10%). After the surgical procedure, all adrenal steroid levels normalized, and mitotane was prescribed as adjuvant therapy. Although the pulmonary nodules were stable at the four-month follow-up, the abdominal CT-scan revealed a heterogeneous nodule (3.7cm) in the left adrenal gland, which was suspicious of metastasis. Conclusion: DOC-producing adrenocortical tumors are heterogeneous regarding tumor size, clinical behavior, hormonal and metabolites secretion, and disease-free and overall survival; however, it is common hypokalemia, hypertension, and other symptoms as abdominal pain, due to tumor growth, and weight loss. The association of arterial hypertension with hypokalemia and elevated 11-deoxycortisol, with normal aldosterone and renin, lead to the need for mineralocorticoid precursors evaluation in patients with adrenocortical tumor.

Abstract
Background: Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy, with a heterogeneous but, frequently, dismal prognosis; patients with metastatic ACC have a five-year survival that ranges between 0 and 28%. Metastatic ACC may be present at diagnosis or during follow-up as disease recurrences. The most common sites of metastatic lesions include the liver, lungs, lymph nodes and bones. The brain has only rarely been reported as a site of metastasis in this neoplasia and, to the authors’ knowledge, little is known regarding the incidence, patterns of clinical presentation and disease progression, and outcomes. Objective: The aim of this report was to describe the clinical characteristics of adult patients with ACC who developed brain metastasis evaluated at a tertiary oncological center (ICESP) from Brazil. Methods: Retrospective analysis of medical records including evaluation of laboratory and imaging exams and pathologic data (in cases where surgical resection of the metastasis was performed). Results: In the last ten years (2009-2019), fifty-four patients have been treated for ACC at ICESP; all of them with advanced disease (locally advanced disease and metastatic disease). The median age at the time of diagnosis of ACC was 44 (range 24-61 yrs.). No patients presented metastasis at central nervous system (CNS) at the initial diagnosis; however, during follow-up, we identified brain metastasis in six patients (11.1%). The median time between ACC diagnosis and the detection of brain metastasis was 20.8 months (range 5-53 mo.). In all of these six cases, at least three other sites of metastatic involvement were already present when the brain involvement was diagnosed and, therefore, all of them had already been treated with mitotane in association with at least one line of cytotoxic chemotherapy. The number of brain metastasis in each of these six patients varied from one to eight and median size of lesion was 1.7 cm (range 0.5-4.0 cm). Secondary headache and seizure were the main symptoms of presentation and one or two of these symptoms occurred in all but in one patient, in which diagnosis was due to screening with brain MRI. In four patients with stable disease elsewhere, surgical resection of one or two brain metastases was performed. In these cases, SF1-positive immunohistochemistry confirmed the adrenocortical origin of the lesion. The median time between CNS metastasis detection and death was 3.8 months (range 0.4-59.6 mo.), and complications due to brain metastasis were the leading cause of death. Conclusions: In our institute, brain metastasis occurred in 11.1% of advanced ACC, a prevalence that is higher than previously reported in literature. Despite the relative small number of patients included in this study, we highlight the possibility of brain metastasis in patients with ACC, particularly in cases with a prolonged disease course and multiple systemic treatments.

Abstract
Introduction: Masses in adrenal topography are diagnosed frequently due to the increase in radiological imaging in clinical practice. Adrenal incidentalomas occur between 4% and 10% of the patients above 50 years undergoing abdominal imaging, and the majority are benign pathologies. Objective: To analyze the characteristics of the masses located in adrenal gland topography not originating from the adrenal gland. Methods: We retrospectively assessed patients from our tertiary hospital who underwent surgical treatment for masses in adrenal gland topography between 2006 and 2018. All patients had hormonal evaluations, according to the European and American Societies of Endocrinology guidelines. Two expert radiologists reviewed all images. Forty-six patients were included in the study, and the surgical specimens were analyzed by the same experienced pathologist. Patients with confirmed adrenocortical carcinoma (ACC) were excluded from this cohort. Results: Thirty-two (69.6%) patients were female. The median age was 49.5 years old (range 18-82yo). Abdominal or lumbar pain was the most frequent reason for medical investigation (43.5%). Adrenal incidentalomas represented 38.4% of the cohort. None of these patients had any clinical signs of adrenal hyperfunction, nor hormonal alteration. Twenty-four patients (52.17%) presented a mass on the left side, and only two cases presented bilateral adrenal masses. The median size was 8.6cm (1.3-18cm). The mean of Hounsfield Units (HU) on a non-contrasted CT was 25HU (0-50HU). Several etiologies were found: 8 cases (18%) of ganglioneuroma; 6 cases (13,5%) of adrenal cysts; 4 cases (9%) of leiomyosarcoma and adrenal hemorrhage; 3 cases (6.5%) of infectious disease; 2 cases (4.5%) of lymphangioma, schwannoma, and sarcoma. We also found single cases of renal cell carcinoma, poorly differentiated small cell neuroendocrine carcinoma, hepatocellular carcinoma, high grade dedifferentiated liposarcoma, epithelioid neoplasia, epithelial neoplasia with neuroendocrine differentiation, malignant peripheral nerve sheath tumor of the adrenal gland, poorly differentiated neuroblastoma, high grade lymphoma, myelolipoma, acute splenitis, arteriovenous malformation, and prostate cancer metastasis. Discussion and Conclusion: Ganglioneuroma was the most frequent diagnosis in adrenal incidentalomas in our cohort. In general, these conventional radiological exams could not differentiate lesions originated in the adrenal glands from lesions of other origins. In this large cohort, we could identify non-adrenal origin in approximately 45% of the patients with masses in the adrenal topography.

Abstract
Background: Adrenocortical carcinoma (ACC) is a rare endocrine malignancy with an unfavorable prognosis. Despite the poor prognosis in the majority of patients, no improvements in treatment strategies have been achieved, largely due to the rarity of these tumors. Therefore, the discovery of new prognostic biomarkers that could guide and improve the management of patients with ACC is of enormous interest. Sterol-O-Acyl Transferase 1 (SOAT1) is involved in cholesterol esterification in adrenocortical cells. Recently, it was demonstrated that SOAT1 inhibition leads to impaired steroidogenesis and cell viability in ACC [1]. There are no studies so far addressing the impact of SOAT1 protein expression in ACC prognosis and clinical outcomes. Methods: We evaluated SOAT1 protein expression by immunohistochemistry (ab39327; 1:4000; Abcam, EUA) in a tissue microarray of 107 adrenocortical carcinomas (Weiss score ≥ 3) from adult patients treated in a single tertiary center in Brazil. Immunohistochemistry results were evaluated through a semiquantitative approach by two independent pathologists. We aimed to evaluate the correlation of SOAT1 protein expression with clinical and biochemical parameters, surgical specimen histological characteristics, recurrence free-survival, progression free-survival and overall survival. Results: SOAT1 protein expression was heterogenous in this cohort; 38% of ACCs demonstrated strong SOAT1 protein expression while 62% demonstrated weak or absent SOAT1 protein expression. Strong SOAT1 protein expression correlates with known features of high aggressiveness in ACC, such as excessive tumor cortisol secretion (p= 0.007), advanced disease stage [ENSAT 3 and ENSAT 4 (p= 0.009)] and high Ki67 index (0.008). On multivariate analysis, strong SOAT1 protein expression was an independent predictor of lower overall survival (HR 1.71, CI 95% 1.05-2.92; p= 0.04) when considering all cases (n= 107) and of lower progression free survival (HR 3.05, CI 95% 1.05-8.85; p= 0.04) in patients with metastatic disease at diagnosis (n= 22). Conclusions: Our findings demonstrated that SOAT1 protein expression has prognostic value in ACC and reinforce the importance of investigating SOAT1 as a possible therapeutic target for patients with ACC. Multicentric prospective studies including a larger number of patients are needed in order to validate and consolidate the results found in this cohort. References: 1. Sbiera S, Leich E et al.

Abstract
Abstract
Adrenocortical carcinoma (ACC) is a rare, aggressive cancer. Up to 75% of patients develop incurable metastatic disease, highlighting an urgent need for novel medical therapies. We recently identified a rapidly progressive ACC subtype characterized by CpG island hypermethylation (CIMP-high), sustained Wnt/β-catenin signaling, steroidogenic differentiation, and cell cycle activation. CIMP-high status alone accounts for 40% of ACC, but predicts 70% of recurrences and >50% of deaths. Intriguingly, hypermethylated CpG islands in CIMP-high ACC are unmethylated in fetal and adult adrenal cortex, suggesting DNA methylation is supported by cancer-specific mechanisms. We therefore sought to investigate how aberrant epigenetic programming contributes to ACC biology. In embryonic stem cells, the Polycomb repressive complex 2 (PRC2) represses differentiation programs through EZH2-mediated histone H3 lysine 27 trimethylation (H3K27me3) deposition in promoter CpG islands free of DNA methylation. Gain or loss of EZH2/PRC2 function prevails in a variety of human cancers, enabling proliferation in a tissue-specific manner. Here, we identify that CIMP-high ACC exhibit high expression of EZH2/H3K27me3, but paradoxically bear DNA hypermethylation in annotated PRC2 target regions. To determine if DNA methylation of PRC2 targets disrupts or is controlled by EZH2, we characterized EZH2’s role in CIMP-high ACC cell line NCI-H295R at baseline and in response to EZH2 inhibition (EZH2i). EZH2-directed IP-MS revealed EZH2 interacts with PRC2 members and DNA methylation-sensitive accessory proteins, but no DNA methyltransferase machinery. ChIP-seq revealed EZH2 and H3K27me3 colocalize in repressive domains genome-wide, but DNA methylation and H3K27me3 are mutually exclusive. EZH2i induced H3K27 demethylation and loss of viability, but with no effect on CIMP-high DNA methylation. These data suggest PRC2 target DNA methylation in CIMP-high ACC is maintained independently of EZH2, enabling EZH2/PRC2 to coordinate alternative programs required for cell survival. We then measured the consequences of EZH2i on the NCI-H295R transcriptome (RNA-seq), EZH2/H3K27me3 deposition genome-wide (ChIP-seq), and chromatin accessibility landscape (ATAC-seq). EZH2i led to global downregulation of cell cycle, Wnt/β-catenin transcriptional programming, and steroidogenic differentiation, partially explained by EZH2i-induced offloading of EZH2 from H3K27me3 domains to accessible promoters genome-wide. Taken together, our studies illustrate how aberrant CpG island hypermethylation in CIMP-high ACC participates in a targetable repressive epigenetic cascade that reinforces oncogenic adrenocortical transcriptional programs. Ultimately, we hope to illuminate novel strategies for tissue-specific disruption of the aberrant epigenetic wiring that defines CIMP-high ACC.

Abstract
Abstract
Background: Congenital Adrenal Hyperplasia (CAH) comprises a spectrum of autosomal recessive diseases, resulting in enzymatic defects in the cortisol secretion. CAH newborn screening can avoid neonatal mortality in children with the salt-wasting form and prevent incorrect gender assignments in females. The occurrence of false-positive results creates diagnostic difficulties presenting therapeutic implications. Beckwith Wiedemann Syndrome (BWS) is a congenital disease characterized by somatic overgrowth, increased risk of neonatal hypoglycemia, and development of embryonic tumors. BWS is due to (epi)genetic changes involving growth-regulating genes with good genotype-phenotype correlation. The adrenal gland is frequently involved and may present diffuse cytomegaly of the adrenal cortex1. We reported a BWS newborn girl with a false-positive diagnosis of CAH in the screening. Case report: The patient was born at 39 weeks from an uneventful cesarean section, 5.6kg (>p97) and 52cm (>p97), referred to the Endocrinology service due to abnormal neonatal tests (neonatal 17-OHP: 96ng/mL) collected at 6 days old. At 14 days old, she was 6.3 kg (Z:+5.59), and 58cm (Z:+2.47), BMI: 18.7 kg/m2 (Z:+4.45), and with typical female external genitalia, ruling out the diagnosis of classic CAH. She presented some syndromic characteristics as macroglossia, ogival palate, orbital hypertelorism, hepatomegaly, and umbilical hernia. At 1 month and 14 days old, serum 17OHP was 7.4ng/mL, androstenedione: 6.1 ng/mL, total testosterone: 279ng/dL, 11-deoxycortisol: 2.11ng/mL, cortisol: 5.0ug/dL, and ACTH: 54pg/mL. At five months old she evolved with normalization of serum 17OHP, androstenedione and testosterone levels (1.36ng/mL, <0.50ng/mL, and 37ng/dL, respectively), but still with high DHEAS levels: 2913ng/mL. At 11 months old, DHEAS also normalized, confirming that it was transient hyperactivity of the zona reticulata. A molecular test was performed in a blood sample by MLPA, showing a gain of methylation in the imprinting control region 1 (ICR1) of chromosome 11p15, which controls two imprinted genes, H19 and IGF-2, confirming the clinical diagnosis of BWS. The hypermethylation of ICR1 is largely related to the Wilms tumor. The patient was diagnosed with bilateral Wilms tumor at 11 months old and undergone chemotherapy without adequate response requiring left nephrectomy at 1 year and 5 days old. Conclusion: We presented the first description of false-positive diagnosis of CAH in the newborn screening of a girl with Beckwith Wiedemann syndrome, probably due to a transient overactivation of the zona reticulata.

Abstract
Background: Aldosterone producing adenomas (APAs) are the most common cause of unilateral primary aldosteronism (PA). In most cases, APAs present as small (<2 cm in diameter) benign appearing nodules on computed tomography (CT). Up to 70% of APAs may harbor KCNJ5 somatic mutations. Clinical Cases: Case 1. A 33-yr-old man was referred to investigate resistant hypertension (HT). Biochemical evaluation revealed normal K levels, aldosterone (A) of 14.7 ng/dl, renin of 2.1 mUI/L (normal, 4.4-46.1) and A/R ratio of 24.8. Confirmatory testing confirmed PA diagnosis. Hypercortisolism investigation revealed a non-suppressible cortisol after an overnight 1 mg low-dose dexamethasone suppression (8.3 μg/dL), abnormal midnight salivary cortisol, and normal urinary free cortisol, plasma DHEAS and ACTH levels. Computed tomography (CT) scan showed a well-limited mass in left adrenal, measuring 5.8 cm with pre-contrast density of 30 HU and absolute wash-out of 72%. After left laparoscopic adrenalectomy, hydrocortisone was started and adrenal insufficiency confirmed by basal cortisol <3 μg/dL. He presented biochemical cure of PA and improvement in HT control. Histologic examination revealed an encapsulated tumor with glomerulosa-like cells predominance and a Weiss score 1 (clear cells <25%). CYP11B2 staining was positive in 10% and Ki67 in 5% of tumor cells. Case 2. A 58 yr-old woman was referred to investigate an adrenal mass. She had resistant HT and hypokalemia since 2010. Biochemical evaluation revealed hypokalemia (2.8 mEq/L), A of 16.9 ng/dl, renin <1.6 mUI/L and A/R ratio of 10.6. Confirmatory testing confirmed PA diagnosis. Hypercortisolism investigation was negative. CT scan showed a heterogeneous solid mass in the right adrenal, measuring 5.5 cm with pre-contrast density of 30 HU and absolute wash-out of 77%. After laparoscopic right adrenalectomy, histologic examination revealed an encapsulated tumor with glomerulosa-like cells predominance and a Weiss score 2 (clear cells < 25% and > 1/3 diffuse architecture). CYP11B2 staining was positive in 30% and Ki67 in 5% of the cells. She presented biochemical cure of PA and improvement in HT control. Genetic investigation for somatic KCNJ5, ATP1A1, ATP2B3 and CTNNB1 was negative in both cases. Conclusion: We describe two rare cases of APAs that presented as large and suspicious tumors, without somatic mutations in genes associated with APAs.

Abstract
Abstract
Introduction: Adrenocortical carcinoma (ACC) is a rare malignancy with an incidence of 1 to 2 cases per million/year in adults and with a global survival rate of less than 40% in 5 years. ACC diagnosis was based on Weiss criteria for adult patients. Pediatric patients with adrenocortical tumors (PAT), in general, are associated with better survival in most cases, and the malignant disease is established when local or distant metastases are found. The integrated and extensive genomic-molecular characterization of ACC has resulted in a better understanding of its pathophysiology. Some studies have demonstrated the involvement of ATRX and ZNRF3 genes in adrenal tumorigenesis in pediatric and adult patients with PAT and ACC, respectively. However, these data have not been validated in a Brazilian cohort with a high prevalence of the TP53 germline R337H mutation. Objectives: We aimed to evaluate the ATRX and ZNRF3 expression and copy number variation in a Brazilian cohort of patients with PAT and adults with ACC from a tertiary center. Patients and Methods: 34 adults (19 women - 56%) with median age 49 years old (range 18-83) and twelve pediatric patients (7 girls - 58%) with median age three years old (0.8-15 years old) were included in this study. The epidemiological data, clinical presentation, hormonal data, radiological imaging, and genetic background for TP53 were retrospectively evaluated. MLPA and RT-PCR were employed to evaluate the copy number variation and the gene expression, respectively, of ATRX and ZNRF3 in tumor tissues. Results: Adult group: Seven patients out of 27 (25.9%) presented the pathogenic germline mutation pR337H onTP53. 20 patients (58.8%) presented metastasis, and 19 (55%) had a fatal outcome. The median global survival was 17.23 months (0.6-185.8 m). Pediatric group: 10 patients (83.3%) presented the pathogenic germline mutation p.R337H on TP53. Four patients presented metastasis and only two had a fatal outcome. The median global survival was 42.4months (6.63-125.5m). All tumors were functional. Molecular results: Three out of 33 adult patients (9%), and 2 out of 12 (16.6%) pediatric patients presented deletion on ATRX. Four out of 25 adults (16%) and 2 out of 12 pediatric (16.6%) patients showed deletion on ZNRF3. There was no correlation between ATRX and ZNRF3 expressions or deletions with the overall survival rate (p>0.05). The decrease in the ATRX expression was associated with the presence of TP53 germline mutation in pediatric and adult cohorts (p 0.028). Conclusion: We confirmed the presence of alterations on ATRX and ZNRF3 genes in both cohort (adult and pediatric tumors). These results differ from the previous studies, which demonstrated ATRX and ZNRF3 alterations were present in pediatric and adult tumors, respectively. However, prospective studies with larger cohorts are necessary to confirm the prognostic value of ATRX and ZNRF3 genes in PAT and adults with ACC.

Abstract
Background: 68Ga DOTATATE PET/CT (68Ga-PET) has been proposed as a superior method in identifying ectopic ACTH syndrome (EAS). However, recent systematic review suggests its sensitivity is not as high as believed (1). We report a challenging case of EAS whose source was uncovered only after repeated 68Ga-PET. Clinical Case: A 15‐year-old male presented with rapid onset of typical features of Cushing’s syndrome (CS) and metabolic impairment. Hormone evaluation confirmed severe ACTH-dependent CS. Pituitary transsphenoidal surgery was performed due to positive responses in desmopressin stimulation and high dose dexamethasone suppression test, in addition to a 4 mm nodule in pituitary MRI. No tumor was found in surgical specimen and no hormonal improvement was observed after surgery. Inferior petrosal sinus sampling demonstrated no central to peripheral ACTH gradient. Neck US, thorax/abdomen/pelvis CT were negative and PET-CT/FDG was inconclusive. OctreoScan® identified anomalous uptake on left mediastinum and led the patient to a thoracic surgery (TS) with nodule resection at left hilum. Pathology confirmed ACTH positive 10 mm neuroendocrine tumor (NET) infiltrating a lymph node. The patient had transient clinical and hormonal improvement, with recurrence 7 months later. Thoracic CT (T-CT) showed a 7 mm nodule on inferior segment of superior left lobe, PET-CT/FDG and OctreoScan® were negative but abnormal uptake was verified by 68Ga-PET in subcarinal area. A sub centimetric lymph node was resected and pathology confirmed ACTH positive NET, although the patient did not achieve remission. Octreotide LAR, cabergoline and ketoconazole did not control hypercortisolism and bilateral adrenalectomy was performed. Then, T-CT showed stable lung nodule and 2nd 68Ga-PET was negative. One year later, T-CT evidenced growth of lung nodule to 15 mm and 3rd 68Ga-PET demonstrated for the first time, abnormal uptake in this area. The patient underwent resection of left superior lung lobe along with ipsilateral hilar lymph nodes, and histopathology study revealed an ACTH-secreting atypical pulmonary carcinoid tumor with Ki67 of 10% and 5 out of 11 lymph nodes affected. ACTH fell from 288 to 64 pg/mL after surgery. Conclusion: Despite the high sensitivity attributed to 68Ga-PET, false negatives have been reported. In the present case, primary tumor was evidenced by 68Ga-PET seven years after the first resection of a metastatic lymph node, in the 3rd 68Ga-PET assessment and after tumor growth. This adds to the evidence that further studies are needed to better assess the accuracy of 68Ga-PET for EAS. Reference: [1] Varlamov et al.

Abstract
ARMC5 (Armadillo repeat containing 5 gene) was identified as a new tumor suppressor gene responsible for hereditary adrenocortical tumors and meningiomas. ARMC5 is ubiquitously expressed and encodes a protein which contains a N-terminal Armadillo repeat domain and a C-terminal BTB (Bric-a-Brac, Tramtrack and Broad-complex) domain, both docking platforms for numerous proteins. At present, expression regulation and mechanisms of action of ARMC5 are almost unknown. In this study, we showed that ARMC5 interacts with CUL3 requiring its BTB domain. This interaction leads to ARMC5 ubiquitination and further degradation by the proteasome. ARMC5 alters cell cycle (G1/S phases and cyclin E accumulation) and this effect is blocked by CUL3. Moreover, missense mutants in the BTB domain of ARMC5, identified in patients with multiple adrenocortical tumors, are neither able to interact and be degraded by CUL3/proteasome nor alter cell cycle. These data show a new mechanism of regulation of the ARMC5 protein and open new perspectives in the understanding of its tumor suppressor activity.

Abstract
Adrenocortical cancer is a rare malignant neoplasm associated with a dismal prognosis. Identification of the molecular pathways involved in adrenal tumorigenesis is essential for a better understanding of the disease mechanism and improvement of its treatment. The aim of this study is to define the prevalence of alterations in DNA mismatch repair (MMR) genes in Lynch syndrome among pediatric patients with adrenocortical neoplasia from southern Brazil, where the prevalence of a specific TP53 germline mutation (p.Arg337His) is quite high. Thirty-six pediatric patients were retrospectively evaluated. Immunohistochemistry (IHC) for the MMR enzymes MLH1, MSH2, MSH6, and PMS2, as well as next-generation sequencing (NGS) were performed. For IHC, 36 pediatric tumors were tested. In all of them, the expression of all evaluated MMR proteins was well-preserved. For NGS, 35 patients with pediatric tumor were tested. Three patients (8.57%) with the TP53 p.Arg337His germline mutation presented pathogenic and likely pathogenic variants in the MMR genes (two in MLH1 and one in MSH6). The prevalence of altered MMR genes among pediatric patients was elevated (8.57%) and higher than in colorectal and endometrial cancer cohorts. Pediatric patients with adrenocortical tumors should, thus, be strongly considered as at genetic risk for Lynch syndrome.

Abstract
Adrenocortical carcinoma (ACC) is a rare endocrine malignancy with an unfavorable prognosis. Despite the poor prognosis in the majority of patients, no improvements in treatment strategies have been achieved. Therefore, the discovery of new prognostic biomarkers is of enormous interest. Sterol-O-acyl transferase 1 (SOAT1) is involved in cholesterol esterification and lipid droplet formation. Recently, it was demonstrated that SOAT1 inhibition leads to impaired steroidogenesis and cell viability in ACC. To date, no studies have addressed the impact of SOAT1 expression on ACC prognosis and clinical outcomes. We evaluated SOAT1 expression by quantitative real-time polymerase chain reaction and immunohistochemistry in a tissue microarray of 112 ACCs (Weiss score ≥ 3) from adults treated in a single tertiary center in Brazil. Two independent pathologists evaluated the immunohistochemistry results through a semiquantitative approach (0-4). We aimed to evaluate the correlation between SOAT1 expression and clinical, biochemical and anatomopathological parameters, recurrence-free survival (RFS), progression-free survival (PFS), and overall survival (OS). SOAT1 protein expression was heterogeneous in this cohort, 37.5% of the ACCs demonstrated a strong SOAT1 protein expression (score > 2), while 62.5% demonstrated a weak or absent protein expression (score ≤ 2). Strong SOAT1 protein expression correlated with features of high aggressiveness in ACC, such as excessive tumor cortisol secretion (p = 0.01), an advanced disease stage [European Network for the Study of Adrenal Tumors (ENSAT) staging system 3 and 4 (p = 0.011)] and a high Ki67 index (p = 0.002). In multivariate analysis, strong SOAT1 protein expression was an independent predictor of a reduced OS (hazard ratio (HR) 2.15, confidence interval (CI) 95% 1.26-3.66; p = 0.005) in all patients (n = 112), and a reduced RFS (HR 2.1, CI 95% 1.09-4.06; p = 0.027) in patients with localized disease at diagnosis (n = 83). Our findings demonstrated that SOAT1 protein expression has prognostic value in ACC and reinforced the importance of investigating SOAT1 as a possible therapeutic target for patients with ACC.

Abstract
Adrenocortical carcinoma (ACC) is a rare endocrine malignancy with an unfavorable prognosis. Despite the poor prognosis in the majority of patients, no improvements in treatment strategies have been achieved. Therefore, the discovery of new prognostic biomarkers is of enormous interest. Sterol-O-acyl transferase 1 (SOAT1) is involved in cholesterol esterification and lipid droplet formation. Recently, it was demonstrated that SOAT1 inhibition leads to impaired steroidogenesis and cell viability in ACC. To date, no studies have addressed the impact of SOAT1 expression on ACC prognosis and clinical outcomes. We evaluated SOAT1 expression by quantitative real-time polymerase chain reaction and immunohistochemistry in a tissue microarray of 112 ACCs (Weiss score ≥ 3) from adults treated in a single tertiary center in Brazil. Two independent pathologists evaluated the immunohistochemistry results through a semiquantitative approach (0–4). We aimed to evaluate the correlation between SOAT1 expression and clinical, biochemical and anatomopathological parameters, recurrence-free survival (RFS), progression-free survival (PFS), and overall survival (OS). SOAT1 protein expression was heterogeneous in this cohort, 37.5% of the ACCs demonstrated a strong SOAT1 protein expression (score > 2), while 62.5% demonstrated a weak or absent protein expression (score ≤ 2). Strong SOAT1 protein expression correlated with features of high aggressiveness in ACC, such as excessive tumor cortisol secretion (p = 0.01), an advanced disease stage [European Network for the Study of Adrenal Tumors (ENSAT) staging system 3 and 4 (p = 0.011)] and a high Ki67 index (p = 0.002). In multivariate analysis, strong SOAT1 protein expression was an independent predictor of a reduced OS (hazard ratio (HR) 2.15, confidence interval (CI) 95% 1.26–3.66; p = 0.005) in all patients (n = 112), and a reduced RFS (HR 2.1, CI 95% 1.09–4.06; p = 0.027) in patients with localized disease at diagnosis (n = 83). Our findings demonstrated that SOAT1 protein expression has prognostic value in ACC and reinforced the importance of investigating SOAT1 as a possible therapeutic target for patients with ACC.

Abstract
Objective: Germline ARMC5 mutations are considered to be the main genetic cause of primary macronodular adrenal hyperplasia (PMAH). PMAH is associated with high variability of cortisol secretion caused from subclinical hypercortisolism to overt Cushing's syndrome (CS), in general due to bilateral adrenal nodules and rarely could also be due to non-synchronic unilateral adrenal nodules. The frequency of adrenal incidentalomas (AI) associated with PMAH is unknown. This study evaluated germline allelic variants of ARMC5 in patients with bilateral and unilateral AI and in patients with overt CS associated with bilateral adrenal nodules. Methods: We performed a retrospective multicenter study involving 123 patients with AI (64 bilateral; 59 unilateral). We also analyzed 20 patients with ACTH pituitary independent overt CS associated with bilateral adrenal nodules. All patients underwent germline genotyping analysis of ARMC5; abdominal CT and were classified as normal, possible or autonomous cortisol secretion, according to the low doses of dexamethasone suppression test. Results: We identified only one pathogenic allelic variant among the patients with bilateral AI. We did not identify any pathogenic allelic variants of ARMC5 in patients with unilateral AI. Thirteen out of 20 patients (65%) with overt CS and bilateral adrenal nodules were carriers of pathogenic germline ARMC5 allelic variants, all previously described. The germline ARMC5 mutation was observed in only one patient with bilateral AI; it was associated with autonomous cortisol secretion and showed to be a familial form. Conclusion: The rarity of germline ARMC5 mutations in AI points to other molecular mechanisms involved in this common adrenal disorder and should be investigated. In contrast, patients with overt Cushing's syndrome and bilateral adrenal nodules had the presence of ARMC5 mutations that were with high prevalence and similar to the literature. Therefore, we recommend the genetic analysis of ARMC5 for patients with established Cushing's syndrome and bilateral adrenal nodules rather than patients with unilateral AI.

Abstract
Adrenocortical carcinoma (ACC) is an aggressive endocrine cancer with few molecular predictors of malignancy and survival, especially in paediatric patients. Stathmin 1 (STMN1) regulates microtubule dynamics and has been involved in the malignant phenotype of cancer cells. Recently, it was reported that STMN1 is highly expressed in ACC patients, and STMN1 silencing reduces the clonogenicity and migration of ACC cell lines. However, the prognostic significance of STMN1 and its therapeutic potential remain undefined in ACC. In the present study, STMN1 mRNA levels were significantly higher (p < 0.05) in ACC patients, especially in an advanced stage, and correlated with BUB1B and PINK1 expression, the prognostic-related genes in ACC. In paediatric tumours, high STMN1 expression was observed in both adrenocortical carcinoma and adrenocortical adenoma patients. Among the adult malignant tumours, STMN1 level was an independent predictor of survival outcomes (overall survival: hazard ratio = 6.08, p = 0.002; disease-free survival: hazard ratio = 4.65, p < 0.0001). Paclitaxel, a microtubule-stabilizing drug, reduces the activation of STMN1 and significantly decreases cell migration and invasion in ACC cell lines and ACC cells from secondary cell culture (all p < 0.0001). In summary, STMN1 expression may be of great value to clinical and pathological findings in therapeutic trials and deserves future studies in ACC.

Abstract
PURPOSE Cushing's disease (CD) is a severe illness generally caused by microcorticotropinomas (MICs) and in approximately 7-20% of patients by macrocorticotropinomas (MACs). USP8-mutations have been identified as a major genetic cause of CD (~ 50%). Few studies have reported the distribution between MICs-MACs related to USP8-mutations and their genotype-phenotype correlations. Therefore, we aimed to evaluate USP8-mutations in a cohort of MICs-MACs from a unique center and to perform a systematic review and meta-analysis. METHODS DNA-tumor-tissues from 47 corticotropinomas (16 MICs and 31 MACs) were sequenced. Clinical-biochemical data, radiological imaging data and remission/recurrence rates were evaluated. In addition, we performed a meta-analysis of nine published series (n = 630). RESULTS We identified four different USP8-mutations previously described, in 11 out of 47 (23.4%) corticotropinomas; 8 out of 11 were MACs. The urinary cortisol levels of our patients with corticotrophin USP8-mutated-alleles were lower than those of patients with wild-type (WT) alleles (p ≤ 0.017). The frequency of USP8-mutated-alleles among the series was approximately 30% with a higher prevalence in female-patients (p < 0.1 × 10-4). Among the 5 series, the remission rates were higher in patients with USP8-mutated-alleles than in those with the USP8-WT-alleles (p < 0.1 × 10-4). CONCLUSION Our data, as well as the retrospective review of CD series associated with USP8-mutated alleles, show heterogeneous findings among the series. Several drawbacks included the lack of a systematic protocol to evaluate these patients before surgery and follow-up. Further prospective studies using a systematic protocol will provide more consistent information about the influence of the corticotropinomas with USP8-mutated alleles on the phenotype, responses to treatment and outcome of patients with CD.

Abstract
BACKGROUND The TP53 p.R337H germline mutation is highly prevalent among children with adrenocortical tumors (ACTs) from South and Southeast Brazil. However, the prevalence of other tumors of the Li-Fraumeni syndrome (LFS) and Li-Fraumeni-like syndrome (LFL) spectrum, the clinical outcomes and the potential tumor occurrence in relatives carrying this distinct TP53 mutation were not fully investigated. PATIENTS AND METHODS We investigated tumor profile data and outcomes of individuals and their close relatives with the TP53 p.R337H germline mutation. A questionnaire and the Toronto protocol were used for evaluation of asymptomatic carriers of this TP53 mutation. RESULTS The cohort of this study comprised 51 patients from 46 different families; 67% were female. All but one harbored the TP53 p.R337H mutation in heterozygous state; only one child was homozygous for this variant. Maternal allele inheritance occurred in 72% of the cases (p= 0,002). In pediatric group, ACT was the most common primary tumor at the diagnosis (55%; median age= 2 years). No patient of the pediatric group who initially presented with ACT developed a second primary tumor and 11% (n= 3) died due to complications related to the primary tumor (median follow-up time of 81.5 months, range= 3-378 months). In adult group, the main tumors at diagnosis were: adrenocortical carcinoma (ACC) (23%; median age= 29.5 years), breast cancer (12%; median age= 38.5 years), soft tissue sarcoma (8%; median age= 50.3 years) and choroid plexus carcinoma (CPC) (2%; median age= 18 years). Among adult patients who were diagnosed with ACC as the first primary tumor, all presented with aggressive disease as per histologic and clinical criteria at diagnosis, and 75% of patients died (median follow-up time of 19 months, range= 1-69 months). Five adult patients (22%) had a second primary tumor, including bronchoalveolar lung cancer (2 cases), ACC, uterine cervical carcinoma and fibrosarcoma. The diagnosis of these tumors was established from 8 to 36 months after the first primary tumor. Three families presented more than one case of ACT. Nine malignant neoplasms were diagnosed in asymptomatic carriers using Toronto protocol. CONCLUSIONS This study confirms a high frequency of TP53 p.R337H mutation in pediatric group with ACT. In addition, we observed the occurrence of other tumors of LFS/LFL spectrum and a difference in the aggressiveness of ACTs depending on the age group in which they were diagnosed. The predominance of maternal mutated allele inheritance was first demonstrated in the affected Brazilian's families.

Abstract
PURPOSE Filamin A (FLNA) expression is related to dopamine receptor type 2 (DRD2) expression in prolactinomas. Nevertheless, in corticotrophinomas, there are few studies about DRD2 expression and no data on FLNA. Therefore, we evaluated FLNA and DRD2 expression in corticotrophinomas and their association with tumor characteristics. METHODS DRD2 and FLNA expression by immunohistochemistry, using H-score, based on the percentage of positive cells in a continuous scale of 0-300, were evaluated in 23 corticotrophinomas samples from patients submitted to neurosurgery. In six patients, treatment with cabergoline was indicated after non curative surgery. RESULTS Twenty-two patients were female and one male. Regarding tumor size, 10 were micro and 12 were macroadenomas. DRD2 expression was found in 89% of cases and did not correlate with FLNA expression. Moreover, the response to cabergoline, observed in 33% of the cases, did not correlate with DRD2 nor FLNA expression. FLNA expression was not associated with clinical and tumor characteristics, except for sphenoid sinus invasion. CONCLUSIONS In our cohort of corticotrophinomas, DRD2 expression was not associated with FLNA expression nor to the response to CAB. Nonetheless, FLNA expression could be related to tumor invasiveness.

Abstract
Objective Fungal infections can affect the adrenal glands, causing primary adrenal insufficiency (PAI). Although endemic to South America, paracoccidioidomycosis (PCM), which can lead to PAI, has gained global relevance with the increase in international travel and migration. Methods The present report describes 3 patients with PAI caused by PCM. Results Patients in cases 1 and 2 both reported indisposition, asthenia, nausea, hyperpigmentation of the skin, hypotension, and weight loss. Complementary exams confirmed PAI due to PCM. Case 1 was serologically diagnosed. In contrast, the definitive diagnosis of case 2 was only reached by computed tomography (CT)-guided adrenal biopsy after negative serologies for PCM. Case 3, with diabetes mellitus, had a history of asthenia, nausea and weight loss after persistent sinusitis. Initially, serologic results were negative for PCM and the patient's CT-guided biopsy resulted in insufficient tissue to obtain a definitive diagnosis. Contrary to the initial hypothesis of invasive aspergillosis, since the only etiological evidence for the patient's clinical condition were positive serologies for Aspergillus fumigatus, histopathologic examination of the specimen provided by a left adrenalectomy finally confirmed PCM as the etiology for PAI in this case as well. Conclusion The 3 cases illustrate the necessity to investigate PAI whenever there are suspicious clinical findings. They also show that fungal infections should be considered among the diagnostic hypotheses during the etiological investigation of PAI. Finally, they teach us that definitive diagnosis of PCM may require direct visualization of the pathogen.

Abstract
Recent advances in molecular genetics investigations of primary macronodular adrenal hyperplasia (PMAH) have been providing new insights for the research on this issue. The cAMP-dependent pathway is physiologically triggered by ACTH and its receptor, MC2-R, in adrenocortical cells. Different mechanisms of this cascade may be altered in some functioning adrenal cortical disorders. Activating somatic mutations of the GNAS gene (known as gsp oncogene) which encodes the stimulatory G protein alpha-subunit (Gsα) have been found in a small number of adrenocortical secreting adenomas and rarely in PMAH. Lately, ARMC5 was linked to the cyclic AMP signaling pathway, which could be implicated in all of mechanisms of cortisol-secreting by macronodules adrenal hyperplasia and the molecular defects in: G protein aberrant receptors; MC2R; GNAS; PRKAR1A; PDE11A; PDE8B. Around 50 % of patient's relatives with PMAH and 30 % of apparently sporadic hypercortisolism carried ARMC5 mutations. Therefore, PMAH is genetically determined more frequently than previously believed. This review summarizes the most important molecular mechanisms involved in PMAH.

Abstract
INTRODUCTION Triple A syndrome (AAAS) is a rare autosomal recessive disorder characterized by alacrima, achalasia, ACTH-resistant adrenal insufficiency, autonomic dysfunction, and progressive neurodegeneration. Increased oxidative stress, demonstrated in patients' fibroblasts in vitro, may be a central disease mechanism. N-acetylcysteine protects renal function in patients with kidney injuries associated with increased oxidative stress and improves viability of AAAS-knockdown adrenal cells in vitro. PATIENT AND RESULTS A boy diagnosed with AAAS presented with short stature and increased oxidative stress in vivo assessed by increased thiobarbituric acid reactive substances (TBARS), which are markers of lipid peroxidation, and by the susceptibility of LDL to oxidation and the capacity of HDL to prevent it. A homozygous missense germline mutation (c.523G>T, p.Val175Phe) in AAAS was identified. N-acetylcysteine (600 mg orally, twice daily) decreased oxidative stress but did not change the patient's growth pattern. CONCLUSIONS An increase in oxidative stress is reported for the first time in vivo in an AAAS patient. N-acetylcysteine was capable of decreasing TBARS levels, reducing the susceptibility of LDL to oxidation and improving the antioxidant role of HDL. The long-term effect of antioxidant treatment should be evaluated to determine the real benefit for the prevention of the degenerative process in AAAS.

Abstract
With recent progress in understanding the pathogenesis of adrenocortical tumors (ACTs), identification of molecular markers to predict their prognosis has become possible. Transcription factor 21 (TCF21)/podocyte-expressed 1 (POD1) is a transcriptional regulatory protein expressed in mesenchymal cells at sites of epithelial-mesenchymal transition during the development of different systems. Adult carcinomas express less TCF21 than adenomas, in addition, the KEGG pathway analysis has shown that BUB1B, among others genes, is negatively correlated with TCF21 expression. The difference between BUB1B and PTEN-induced putative kinase 1 (PINK1) expression has been described previously to be associated with survival in adult but not in pediatric carcinomas. Here, we analyzed the gene expression of TCF21, BUB1B, PINK1, and NR5A1 in adult and pediatric ACTs. We found a negative correlation between the relative expression levels of TCF21 and BUB1B in adult ACTs, but the relative expression levels of TCF21, BUB1B, PINK1, and NR5A1 were similar in childhood ACTs. In addition, we propose using the subtracted expression levels of the TCF21/POD-1 genes as a predictor of overall survival (OS) in adult carcinomas and TCF21-NR5A1 as a predictor of malignancy for pediatric tumors in patients aged <5 years. These results require further validation in different cohorts of both adult and pediatric samples. Finally, we observed that the OS for patients aged <5 years was markedly favorable compared with that for patients >5 years as well as adult patients with carcinoma. In summary, we propose TCF21/POD-1 as a new prognostic marker in adult and pediatric ACTs.

Abstract
Neuroendocrine tumours are a heterogeneous group of diseases with a significant variety of diagnostic tests and treatment modalities. Guidelines were developed by North American and European groups to recommend their best management. However, local particularities and relativisms found worldwide led us to create Brazilian guidelines. Our consensus considered the best feasible strategies in an environment involving more limited resources. We believe that our recommendations may be extended to other countries with similar economic standards.

Abstract
BACKGROUND/AIMS Although craniopharyngioma (CP) is histologically benign, it is a pituitary tumour that grows rapidly and often recurs. Adamantinomatous CP (ACP) was associated with an activating mutation in β-catenin, and it has been postulated that pituitary stem cells might play a role in oncogenesis in human ACP. Stem cells have also been identified in pituitary adenoma. Our aim was to characterize the expression pattern of ABCG2, CD44, DLL4, NANOG, NOTCH2, POU5F1/OCT4, SOX2, and SOX9 stem cell markers in human ACP and pituitary adenoma. METHODS AND RESULTS We studied 33 patients (9 ACP and 24 adenoma) using real-time quantitative PCR (RT-qPCR) and immunohistochemistry. SOX9 was up-regulated in ACP, exhibiting positive immunostaining in the epithelium and stroma, with the highest expression in patients with recurrence. CD44 was overexpressed in ACP as confirmed by immunohistochemistry. SOX2 did not significantly differ among the tumour types. The RT-qPCR array showed an increased expression of MKI67,OCT4/POU5F1, and DLL4 in all tumours. NANOG was decreased in ACP. ABCG2 was down-regulated in most of the tumours. NOTCH2 was significantly decreased in the adenomas. CONCLUSION Our results confirm the presence of stem cell markers in human pituitary tumours as well as the different expression patterns of ACP and adenoma. These findings suggest that ACP may originate from a more undifferentiated cell cluster. Additionally, SOX9 immunodetection in the stroma and the highest expression levels related to the relapse of patients suggest a contribution to the aggressive behaviour and high recurrence of this tumour type.

Abstract
ACTH-dependent hypercortisolism caused by a pituitary adenoma [Cushing's disease (CD)] is the most common cause of endogenous Cushing's syndrome. CD is often associated with several morbidities, including hypertension, diabetes, osteoporosis/bone fractures, secondary infections, and increased cardiovascular mortality. While the majority (≈80%) of the corticotrophinomas visible on pituitary magnetic resonance imaging are microadenomas (MICs, <10 mm of diameter), some tumors are macroadenomas (MACs, ≥10 mm) with increased growth potential and invasiveness, exceptionally exhibiting malignant demeanor. In addition, larger and invasive MACs are associated with a significant increased risk of local complications, such as hypopituitarism and visual defects. Given the clinical and molecular heterogeneity of corticotrophinomas, the aim of this study was to investigate the pattern of genetic differential expression between MIC and MAC, including the invasiveness grade as a criterion for categorizing these tumors. In this study, were included tumor samples from patients with clinical, laboratorial, radiological, and histopathological diagnosis of hypercortisolism due to an ACTH-producing pituitary adenoma. Differential gene expression was studied using an Affymetrix microarray platform in 12 corticotrophinomas, classified as non-invasive MIC (n = 4) and MAC (n = 5), and invasive MAC (n = 3), according to modified Hardy criteria. Somatic mutations in USP8 were also investigated, but none of the patients exhibited USP8 variants. Differential expression analysis demonstrated that non-invasive MIC and MAC have a similar genetic signature, while invasive MACs exhibited a differential expression profile. Among the genes differentially expressed, we highlighted CCND2, ZNF676, DAPK1, and TIMP2, and their differential expression was validated through quantitative real-time PCR in another cohort of 15 non-invasive and 3 invasive cortocotrophinomas. We also identified potential biological pathways associated with growth and invasiveness, TGF-β and G protein signaling pathways, DNA damage response pathway, and pathways associated with focal adhesion. Our study revealed a differential pattern of genetic signature in a subgroup of MAC, supporting a genetic influence on corticotrophinomas in patients with CD.

Abstract
PURPOSE Pituitary macroadenomas (MACs) represent 10-30 % of Cushing's disease (CD) cases. The aim of this study was to report the clinical, laboratorial and imaging features and postsurgical outcomes of microadenoma (MIC) and MAC patients. METHODS Retrospective study with 317 CD patients (median 32 years old, range 9-71 years) admitted between 1990 and 2014, 74 (23.3 %) of whom had MAC. RESULTS Hirsutism, plethora facial, muscular weakness and muscular atrophy were more frequent in the MIC patients. Nephrolithiasis, osteopenia, hyperprolactinaemia and galactorrhoea were more prevalent in MAC patients. The morning serum cortisol (Fs), nocturnal salivary cortisol (NSC), nocturnal Fs (Fs 2400 h), low- and high-dose dexamethasone suppression test results and CRH and desmopressin test results were similar between the subgroups. MIC patients showed higher urinary cortisol at 24 h (UC), and MAC patients presented higher ACTH levels but lower Fs/ACTH, Fs 2400 h/ACTH, NSC/ACTH and UC/ACTH ratios. There were negative correlations of tumour size with Fs/ACTH, Fs 2400 h/ACTH, NSC/ACTH and UC/ACTH ratios. Overall, the postsurgical remission and recurrence rates were similar between MIC and MAC. However, patients in remission (MIC + MAC) showed smaller tumour diameters and a lower prevalence of invasion and extension on MRI. CONCLUSIONS Despite exhibiting higher plasma ACTH levels, CD patients with MAC presented lower cortisol/ACTH ratios than did patients with MIC, with a negative correlation between tumour size and cortisol/ACTH ratios. The overall postsurgical remission and recurrence rates were similar between MIC and MAC patients, with those with larger and/or invasive tumours showing a lower remission rate.

Abstract
OBJECTIVES: To evaluate the safety and long-term efficacy of computed tomography-guided percutaneous ethanol ablation for benign primary and secondary hyperfunctioning adrenal disorders. METHOD: We retrospectively evaluated the long-term results of nine patients treated with computed tomography-guided percutaneous ethanol ablation: eight subjects who presented with primary adrenal disorders, such as pheochromocytoma, primary macronodular adrenal hyperplasia and aldosterone-producing adenoma, and one subject with Cushing disease refractory to conventional treatment. Eleven sessions were performed for the nine patients. The patient data were reviewed for the clinical outcome and procedure-related complications over ten years. RESULTS: Patients with aldosterone-producing adenoma had clinical improvement: symptoms recurred in one case 96 months after ethanol ablation, and the other patient was still in remission 110 months later. All patients with pheochromocytoma had clinical improvement but were eventually submitted to surgery for complete remission. No significant clinical improvement was seen in patients with hypercortisolism due to primary macronodular adrenal hyperplasia or Cushing disease. Major complications were seen in five of the eleven procedures and included cardiovascular instability and myocardial infarction. Minor complications attributed to sedation were seen in two patients. CONCLUSION: Computed tomography-guided ethanol ablation does not appear to be suitable for the long-term treatment of hyperfunctioning adrenal disorders and is not without risks.
