    Evidence for a Founder Effect of SDHB Exon 1 Deletion in Brazilian Patients With Paraganglioma
    (2023) FAGUNDES, Gustavo F. C.; FREITAS-CASTRO, Felipe; SANTANA, Lucas S.; AFONSO, Ana Caroline F.; PETENUCI, Janaina; FUNARI, Mariana F. A.; GUIMARAES, Augusto G.; LEDESMA, Felipe L.; PEREIRA, Maria Adelaide A.; VICTOR, Carolina R.; FERRARI, Marcela S. M.; COELHO, Fernando M. A.; SROUGI, Victor; TANNO, Fabio Y.; CHAMBO, Jose L.; LATRONICO, Ana Claudia; MENDONCA, Berenice B.; V, Maria Candida B. Fragoso; HOFF, Ana O.; ALMEIDA, Madson Q.
    Context Limited information is available concerning the genetic spectrum of pheochromocytoma and paraganglioma (PPGL) patients in South America. Germline SDHB large deletions are very rare worldwide, but most of the individuals harboring the SDHB exon 1 deletion originated from the Iberian Peninsula. Objective Our aim was to investigate the spectrum of SDHB genetic defects in a large cohort of Brazilian patients with PPGLs. Methods Genetic investigation of 155 index PPGL patients was performed by Sanger DNA sequencing, multiplex ligation-dependent probe amplification, and/or target next-generation sequencing panel. Common ancestrality was investigated by microsatellite genotyping with haplotype reconstruction, and analysis of deletion breakpoint. Results Among 155 index patients, heterozygous germline SDHB pathogenic or likely pathogenic variants were identified in 22 cases (14.2%). The heterozygous SDHB exon 1 complete deletion was the most frequent genetic defect in SDHB, identified in 8 out of 22 (36%) of patients. Haplotype analysis of 5 SDHB flanking microsatellite markers demonstrated a significant difference in haplotype frequencies in a case-control permutation test (P = 0.03). More precisely, 3 closer/informative microsatellites were shared by 6 out of 8 apparently unrelated cases (75%) (SDHB-GATA29A05-D1S2826-D1S2644 | SDHB-186-130-213), which was observed in only 1 chromosome (1/42) without SDHB exon 1 deletion (X-2 = 29.43; P < 0.001). Moreover, all cases with SDHB exon 1 deletion had the same gene breakpoint pattern of a 15 678 bp deletion previously described in the Iberian Peninsula, indicating a common origin. Conclusion The germline heterozygous SDHB exon 1 deletion was the most frequent genetic defect in the Brazilian PPGL cohort. Our findings demonstrated a founder effect for the SDHB exon 1 deletion in Brazilian patients with paragangliomas.

    The effect of hormonal secretion on survival in adrenocortical carcinoma: A multi-center study
    (2024) SADA, Alaa; FOSTER, Trenton R.; AL-WARD, Ruaa; SAWANI, Sahar; CHARCHAR, Helaine; PISHDAD, Reza; BEN-SHLOMO, Anat; DY, Benzon M.; LYDEN, Melanie L.; BERGSLAND, Emily; JASIM, Sina; RAJ, Nitya; SHANK, Jessica B.; HAMIDI, Oksana; HAMRAHIAN, Amir H.; CHAMBO, Jose L.; SROUGI, Victor; FRAGOSO, Maria C. B. V.; GRAHAM, Paul H.; HABRA, Mouhammed Amir; BANCOS, Irina; MCKENZIE, Travis J.
    Background: Current evidence suggests that cortisol secreting adrenocortical carcinoma has worse prognosis compared to non-secreting adrenocortical carcinoma. However, the effect of other secretory subtypes is unknown.Methods: This multicenter study within the American-Australian-Asian Adrenal Alliance included adults with adrenocortical carcinoma (1997-2020). We compared overall survival and disease-free survival among cortisol secreting, mixed cortisol/androgen secreting, androgen secreting, and non-secreting adrenocortical carcinoma.Results: Of the 807 patients (mean age 50), 719 included in the secretory subtype analysis: 24.5% were cortisol secreting, 13% androgen secreting, 28% mixed cortisol/androgen, 32.5% non-secreting, and 2% were mineralocorticoid secreting. Median overall survival and disease-free survival for the entire cohort were 60 and 9 months, respectively.Median overall survival was 36 months for cortisol, 30 for mixed, 60 for androgen secreting, and 115 for non-secreting adrenocortical carcinoma, P < .01. Median disease-free survival was 7 months for cortisol, 8 for mixed, 10 for androgen, and 12 for non-secreting adrenocortical carcinoma, P 1/4 .06. On multivariable analysis of age, sex, Ki67%, secretory subtype, stage, resection, and adjuvant therapy, predictors of worse overall survival were older age, higher Ki67%, stage IV, mixed secreting, R1, and no adjuvant therapy, P < .05. On subgroup analysis of R0 resection, predictors of worse overall survival included older age and higher Ki67%. Ki67% >= 40, stage III and cortisol secretion were associated with worse disease-free survival.Conclusion: Mixed cortisol/androgen secreting adrenocortical carcinoma was associated with worse overall survival, while cortisol or androgen secreting alone were not. Notably, among patients after R0 resection, secretory subtype did not affect overall survival. Cortisol secreting adrenocortical carcinoma demonstrated worse disease-free survival. Ki67% remained a strong predictor of worse overall survival and disease-free survival independent of stage.(c) 2023 Elsevier Inc. All rights reserved.

    The effects of cabergoline in the presurgical and recurrence periods of Cushing's disease patients
    (2021) PEREIRA, Ana Julia Garcia; ANDRADE, Natalia Xavier Sant' Anna; MUSOLINO, Nina Rosa Castro; CESCATO, Valter Angelo Sperling; SILVA, Gilberto Ochman; FRAGOSO, Maria Candida; BRONSTEIN, Marcello D.; MACHADO, Marcio C.
    Background: The dopaminergic agonist cabergoline (CAB) has been used in the pharmacological treatment of Cushing's disease (CD). The effect is attributed to the frequent expression of the dopamine receptor subtype 2 in corticotroph tumors. However, in vivo studies have demonstrated the normalization of 24-h urinary cortisol (24-h UC) in approximately 30-40% of patients over the long term, mainly after surgical failure. Objective: To evaluate the effect of CAB as monotherapy in the early preoperative period and on the recurrence of CD. Methods: A single-center retrospective study was conducted in a tertiary referral center. Twenty-one patients with confirmed CD were included. The median age was 32 years (13-70), 86% were female, 10 had microadenomas, and 11 had macroadenomas. They were diagnosed from 1986 to 2016 and used CAB as monotherapy either in the preoperative period (n=7, CABi) or upon recurrence before any other treatment (n=14, CABr). A 'complete response' was considered 24-h UC normalization and a 'partial response' was considered a 24-h UC reduction of >50%. UC was obtained at the last follow-up evaluation. The normalization of late-night salivary cortisol (LNSC) after CAB use was evaluated in most patients, as well as the 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 an average dose of 2.2 +/- 1.0 mg/week. Partial response occurred in 9.5% (2/21). LNSC normalized in 35% (6/17) of patients, 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. There was no normalization of 24-h-UC in the CABi subgroup at the end of the treatment, whereas 43% (6/14) of patients in the CABr subgroup reached complete response. The CABi subgroup was treated for 4.7 +/- 1.9 months, and the CABr subgroup was treated for 20.1 +/- 18.1 months. Both groups were administered similar doses of CAB (CABi 2.1 +/- 0.9 and CABr 2.3 +/- 1.1 mg/week). Interestingly, the difference between the subgroups' complete response was evident early on in the three months of treatment: no patients in the CABi subgroup vs. 6/10 (60%) in the CABr subgroup (p=0.035), despite a lower dose in the CABr subgroup (1.1 vs. 1.6; p=0.008). The normalization of LNSC occurred in 20% of the CABi subgroup and in 42% of the CABr subgroup. Conclusions: The normalization of 24-h UC and LNSC occurred in approximately 30% of all patients, mainly in those who used CAB for the recurrence of CD. Despite the small number of subjects in the CABi subgroup, the absence of hormone control in this subgroup discourages the use of this medication as primary therapy or as a preoperative treatment option.

    Retrospective Analysis of Prognostic Factors in Pediatric Patients with Adrenocortical Tumor from Unique Tertiary Center with Long-Term Follow-Up
    (2022) BACHEGA, Fernanda S.; V, Caio Suartz; ALMEIDA, Madson Q.; BRONDANI, Vania B.; CHARCHAR, Helaine L. S.; LACOMBE, Amanda M. F.; MARTINS-FILHO, Sebastiao N.; SOARES, Ibere C.; ZERBINI, Maria Claudia N.; DENES, Francisco T.; MENDONCA, Berenice; I, Roberto Lopes; LATRONICO, Ana Claudia; V, Maria Candida B. Fragoso
    Pediatric adrenocortical tumors (PACTs) represent rare causes of malignancies. However, the south/southeast regions of Brazil are known to have a high incidence of PACTs because of the founder effect associated with a germline pathogenic variant of tumor suppressor gene TP53. We aimed to retrospectively analyze the types of variables among hormone production, radiological imaging, tumor staging, histological and genetic features that were associated with the occurrence of malignancy in 95 patients (71% females) with PACTs from a unique center. The worst prognosis was associated with those aged > 3 years (p < 0.05), high serum levels of 11-desoxicortisol (p < 0.001), tumor weight >= 200 g (p < 0.001), tumor size >= 5 cm (p < 0.05), Weiss score >= 5 (p < 0.05), Wieneke index >= 3 (p < 0.001) and Ki67 >= 15% (p < 0.05). Furthermore, patients with MacFarlane stage IV had an overall survival rate almost two times shorter than patients with other stages (p < 0.001). Additionally, the subtractions of BUB1B-PINK1 (<6.95) expression (p < 0.05) and IGF-IR overexpression (p = 0.0001) were associated with malignant behavior. These results helped identify patients who are likely to have an aggressive course; further multicenter prospective studies are required to confirm our results. In conclusion, PACTs with these patterns of prognostic factors could be treated using an adjuvant approach that may improve the overall survival in such patients.

    IMPORTANCE Large studies investigating long-term outcomes of patients with bilateral pheochromocytomas treated with either total or cortical-sparing adrenalectomies are needed to inform clinical management. OBJECTIVE To determine the association of total vs cortical-sparing adrenalectomy with pheochromocytoma-specific mortality, the burden of primary adrenal insufficiency after bilateral adrenalectomy, and the risk of pheochromocytoma recurrence. DESIGN, SETTING, AND PARTICIPANTS This cohort study used data from a multicenter consortium-based registry for 625 patients treated for bilateral pheochromocytomas between 1950 and 2018. Data were analyzed from September 1, 2018, to June 1, 2019. EXPOSURES Total or cortical-sparing adrenalectomy. MAIN OUTCOMES AND MEASURES Primary adrenal insufficiency, recurrent pheochromocytoma, and mortality. RESULTS Of 625 patients (300 [48%] female) with a median (interquartile range [IQR]) age of 30 (22-40) years at diagnosis, 401 (64%) were diagnosed with synchronous bilateral pheochromocytomas and 224 (36%) were diagnosed with metachronous pheochromocytomas (median [IQR] interval to second adrenalectomy, 6 [1-13] years). In 505 of 526 tested patients (96%), germline mutationswere detected in the genes RET (282 patients [54%]), VHL (184 patients [35%]), and other genes (39 patients [7%]). Of 849 adrenalectomies performed in 625 patients, 324 (52%) were planned as cortical sparing and were successful in 248 of 324 patients (76.5%). Primary adrenal insufficiency occurred in all patients treated with total adrenalectomy but only in 23.5% of patients treated with attempted cortical-sparing adrenalectomy. A third of patients with adrenal insufficiency developed complications, such as adrenal crisis or iatrogenic Cushing syndrome. Of 377 patients who became steroid dependent, 67 (18%) developed at least 1 adrenal crisis and 50 (13%) developed iatrogenic Cushing syndrome during median (IQR) follow-up of 8 (3-25) years. Two patients developed recurrent pheochromocytoma in the adrenal bed despite total adrenalectomy. In contrast, 33 patients (13%) treated with successful cortical-sparing adrenalectomy developed another pheochromocytoma within the remnant adrenal after a median (IQR) of 8 (4-13) years, all of which were successfully treated with another surgery. Cortical-sparing surgery was not associated with survival. Overall survivalwas associated with comorbidities unrelated to pheochromocytoma: of 63 patients who died, only 3 (5%) died of metastatic pheochromocytoma. CONCLUSIONS AND RELEVANCE Patients undergoing cortical-sparing adrenalectomy did not demonstrate decreased survival, despite development of recurrent pheochromocytoma in 13%. Cortical-sparing adrenalectomy should be considered in all patients with hereditary pheochromocytoma.

    A matched case-control study of the prognosis of early breast cancer in patients with Li-Fraumeni syndrome (BREAST TP53)
    (2023) PETRY, Vanessa; BONADIO, Renata Colombo; TESTA, Laura; COHN, Daniela JBH.; CAGNACCI, Allyne; CAMPOS, Roberta G.; FRAGOSO, Maria Candida Bv; ESTEVEZ-DIZ, Maria del Pilar
    Introduction: Breast cancer (BC) is the most common type of cancer in premenopausal women with germline TP53 pathogenic variants (mTP53) (Li Fraumeni syndrome -LFS). However, little is known about the BC prognosis in these patients. This study analyzed the BC-related oncologic outcomes of patients with LFS.Methods: We evaluated a cohort of LFS patients with BC in comparison with a control cohort of BC patients with no pathogenic variant in a hereditary cancer panel. The primary endpoint was recurrence-free survival (RFS). Due to the risk of second malignancies in LFS, only locoregional and distant recurrences were considered events for RFS. Secondary endpoints included rates of contralateral BC, overall survival (OS), and breast cancer-specific survival (BCSS).Results: Forty-one patients were evaluated in the mTP53 group and 82 in the control group. Median age at BC diagnosis was 40 and 41 years, respectively. The mTP53 group received less adjuvant radiotherapy than the control group (63.4% vs 93.9%, P < 0.001). Other relevant baseline characteristics and treatment received were similar between groups. 5y-RFS rates were 79.4% in the mTP53 versus 93.6% in the control group (HR 2.43, 95% CI 0.74-8.01, P = 0.143); and were not impacted by the use of adjuvant radiotherapy. 5y-BCSS rates were 92.2% and 98.6%, respectively (HR 1.87, IC95% 0.25-13.48, P = 0.534).Conclusions: Our results showed no statistically significant difference in BC-related RFS and BCSS between pa-tients with mTP53 and a control group with no pathogenic variant. Larger multicentric studies are warranted to confirm these results.

    A New Insight into the Surgical Treatment of Primary Macronodular Adrenal Hyperplasia
    (2020) TANNO, Fabio Yoshiaki; SROUGI, Victor; ALMEIDA, Madson Q.; YAMAUCHI, Fernando Ide; COELHO, Fernando Morbeck Almeida; NISHI, Mirian Yumie; ZERBINI, Maria Claudia Nogueira; SOARES, Iracy Silvia Correa; PEREIRA, Maria Adelaide Albergaria; CHARCHAR, Helaine Laiz Silva; LACOMBE, Amanda Meneses Ferreira; BRONDANI, Vania Balderrama; SROUGI, Miguel; NAHAS, Willian Carlos; MENDONCA, Berenice B.; CHAMBO, Jose Luis; FRAGOSO, Maria Candida Barisson Villares
    Purpose: This prospective study presents the results of a new approach in the treatment of primary macronodular adrenal hyperplasia (PMAII), 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.

    Clinical and molecular aspects of a pediatric metachronous adrenocortical tumor
    (2011) LIMA, Lorena de Oliveira; LERARIO, Antonio Marcondes; ALENCAR, Guilherme Asmar; BRITO, Luciana Pinto; ALMEIDA, Madson Queiroz; DOMENICE, Sorahia; LATRONICO, Ana Claudia; MENDONCA, Berenice Bilharinho; FRAGOSO, Maria Candida Barrison Villares
    The occurrence of metachronous adrenocortical carcinoma has rarely been described. We report a case of a child with virilizing adrenocortical metachronous tumors that, despite several metastases, presented long-term survival (15 years). We analyzed in this tumor IGF2, IGF1R and FGFR4 gene expression, and evaluated the presence of p.R337H germline p53 mutation and somatic CTNNB1 mutation. IGF2 gene was over-expressed in both left (Weiss score 5) and right (Weiss 7) adrenocortical tumors. IGF1R expression levels were higher in the right adrenocortical tumor. FGFR4 over-expression was also detected in the right adrenocortical tumor. In addition, this patient harbors the germline p.R337H p53 mutation and loss of heterozygosity (LOH) was detected in the tumors. No somatic CTNNB1 mutations were found in both tumors. In conclusion, we demonstrated in this unusual case the over-expression of growth signaling pathways, which are molecular mechanisms previously related to adrenocortical tumorigenesis. Furthermore, the absence of somatic CTNNB1 mutations, which is a molecular marker of poor prognosis in adults, might be related to the long-term survival of this patient.
