    Cytoreductive Surgery of the Primary Tumor in Metastatic Adrenocortical Carcinoma: Impact on Patients' Survival
    (2022) SROUGI, Victor; BANCOS, Irina; DAHER, Marilyne; LEE, Jeffrey E.; GRAHAM, Paul H.; KARAM, Jose A.; HENRIQUEZ, Andres; MCKENZIE, Travis J.; SADA, Alaa; BOURDEAU, Isabelle; POIRIER, Jonathan; VAIDYA, Anand; ABBONDANZA, Tiffany; KIERNAN, Colleen M.; RAO, Sarika N.; HAMIDI, Oksana; SACHITHANANDAN, Nirupa; HOFF, Ana O.; CHAMBO, Jose L.; ALMEIDA, Madson Q.; HABRA, Mouhammed Amir; V, Maria C. B. Fragoso
    Context The role of cytoreduction of adrenocortical carcinoma (ACC) remains poorly understood. Objective To analyze the impact of cytoreductive surgery of the primary tumor in patients with metastatic ACC. Design and Setting We performed a multicentric, retrospective paired cohort study comparing the overall survival (OS) in patients with metastatic ACC who were treated either with cytoreductive surgery (CR group) or without cytoreductive surgery (no-CR group) of the primary tumor. Data were retrieved from 9 referral centers in the American-Australian-Asian Adrenal Alliance collaborative research group. Patients Patients aged >= 18 years with metastatic ACC at initial presentation who were treated between January 1, 1995, and May 31, 2019. Intervention Performance (or not) of cytoreductive surgery of the primary tumor. Main outcome and measures A propensity score match was done using age and the number of organs with metastasis (<= 2 or >2). The main outcome was OS, determined from the date of diagnosis until death or until last follow-up for living patients. Results Of 339 patients pooled, 239 were paired and included: 128 in the CR group and 111 in the no-CR group. The mean follow-up was 67 months. Patients in the no-CR group had greater risk of death than did patients in the CR group (hazard ratio [HR] = 3.18; 95% CI, 2.34-4.32). Independent predictors of survival included age (HR = 1.02; 95% CI, 1.00-1.03), hormone excess (HR = 2.56; 95% CI, 1.66-3.92), and local metastasis therapy (HR = 0.41; 95% CI, 0.47-0.65). Conclusion Cytoreductive surgery of the primary tumor in patients with metastatic ACC is associated with prolonged survival.

    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.

    Genetic and clinical aspects of paediatric pheochromocytomas and paragangliomas
    (2021) PETENUCI, Janaina; GUIMARAES, Augusto G.; FAGUNDES, Gustavo F. C.; BENEDETTI, Anna Flavia F.; AFONSO, Ana Caroline F.; PEREIRA, Maria Adelaide A.; ZERBINI, Maria Claudia N.; SIQUEIRA, Sheila; YAMAUCHI, Fernando; SOARES, Silvia C.; SROUGI, Victor; TANNO, Fabio Y.; CHAMBO, Jose L.; I, Roberto Lopes; DENES, Francisco T.; HOFF, Ana O.; LATRONICO, Ana Claudia; MENDONCA, Berenice B.; V, Maria Candida B. Fragoso; ALMEIDA, Madson Q.
    Objective Few and conflicting reports have characterized the genetics of paediatric pheochromocytomas and paragangliomas (PPGLs). This study aimed to investigate the clinical and genetic features of Brazilian children with PPGL. Patients and Methods This study included 25 children (52% girls) with PPGL. The median age at diagnosis was 15 years (4-19). The median time of follow-up was 145 months. The genetic investigation was performed by Sanger DNA sequencing, multiplex ligation-dependent probe amplification and/or target next-generation sequencing panel. Results Of the 25 children with PPGL, 11 (44%), 4 (16%), 2 (8%), 1 (4%) and 7 (28%) had germline VHL pathogenic variants, SDHB, SDHD, RET and negative genetic investigation, respectively. Children with germline VHL missense pathogenic variants were younger than those with SDHB or SDHD genetic defects [median (range), 12 (4-16) vs. 15.5 (14-19) years; P = .027]. Moreover, 10 of 11 cases with VHL pathogenic variants had bilateral pheochromocytoma (six asynchronous and four synchronous). All children with germline SDHB pathogenic variants presented with abdominal paraganglioma (one of them malignant). The two cases with SDHD pathogenic variants presented with head and neck paraganglioma. Among the cases without a genetic diagnosis, 6 and 2 had pheochromocytoma and paraganglioma, respectively. Furthermore, metastatic PPGL was diagnosed in four (16%) of 25 PPGL. Conclusions Most of the paediatric PPGL were hereditary and multifocal. The majority of the affected genes belong to pseudohypoxic cluster 1, with VHL being the most frequently mutated. Therefore, our findings impact surgical management and surveillance of children with PPGL.

    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.

    Internal validation and decision curve analysis of a preoperative nomogram predicting a postoperative complication in pheochromocytoma surgery: An international study
    (2020) PHILLIPS, John; BLOOM, Jonathan; YARLAGADDA, Vidhush; SCHULTZ, Luciana; GORDETSKY, Jennifer; TANNO, Fabio Y.; CHAMBO, Jose L.; ALMEIDA, Madson Q.; V, Maria C. B. Fragoso; SROUGI, Miguel; SROUGI, Victor; RAIS-BAHRAMI, Soroush
    Objectives To develop a preoperative nomogram that would predict the risk of a postoperative complication for pheochromocytoma patients undergoing adrenalectomy using an international database. Methods We retrospectively analyzed preoperative variables and postoperative outcomes in patients who underwent adrenalectomy for pheochromocytoma in three institutions from 2000 to 2017. Internal validation of a generated nomogram was carried out with receiver operating characteristics, calibration plots, and decision curve analyses. Results A total of 153 patients who had undergone 166 adrenalectomies were included in the study. Overall, post-adrenalectomy complications were seen in 30% of patients, whereas 9.6% of patients sustained a Clavien >= 3a complication. Independent predictors of a complication were a history of hypertension, body mass index, tumor size, and Charlson Comorbidity Index score. On internal validation, the multivariable model generated a nomogram that predicted a postoperative complication or clinically hemodynamic event with an area under the curve of 0.86, showed good calibration and had an overall net benefit. Conclusions An internally validated nomogram combining body mass index, Charlson Comorbidity Index score and tumor size can predict the probability of a post-adrenalectomy complication in those with and without hypertension. The model, the first of its kind in pheochromocytoma surgery, identifies patients at risk of a postoperative complication at the time of their presentation with pheochromocytoma.

    Predictors of complication after adrenalectomy
    (2019) SROUGI, Victor; BARBOSA, Joao A. B.; MASSAUD, Isaac; CAVALCANTE, Isadora P.; TANNO, Fabio Y.; ALMEIDA, Madson Q.; SROUGI, Miguel; FRAGOSO, Maria C.; CHAMBO, Jose L.
    Purpose: To investigate risk factors for complications in patients undergoing adrenalectomy. Materials and Methods: A retrospective search of our institutional database was performed of patients who underwent adrenalectomy, between 2014 and 2018. Clinical parameters and adrenal disorder characteristics were assessed and correlated to intra and post-operative course. Complications were analyzed within 30-days after surgery. A logistic regression was performed in order to identify independent predictors of morbidity in patients after adrenalectomy. Results: The files of 154 patients were reviewed. Median age and Body Mass Index (BMI) were 52-years and 27.8kg/m(2), respectively. Mean tumor size was 4.9 +/- 4cm. Median surgery duration and estimated blood loss were 140min and 50mL, respectively. There were six conversions to open surgery. Minor and major post-operative complications occurred in 17.5% and 8.4% of the patients. Intra-operative complications occurred in 26.6% of the patients. Four patients died. Mean hospitalization duration was 4-days (Interquartile Range: 3-8). Patients age (p=0.004), comorbidities (p=0.003) and pathological diagnosis (p=0.003) were independent predictors of post-operative complications. Tumor size (p<0.001) and BMI (p=0.009) were independent predictors of intra-operative complications. Pathological diagnosis (p<0.001) and Charlson score (p=0.013) were independent predictors of death. Conclusion: Diligent care is needed with older patients, with multiple comorbidities and harboring unfavorable adrenal disorders (adrenocortical carcinoma and pheocromocytoma), who have greater risk of post-operative complications. Patients with elevated BMI and larger tumors have higher risk of intra, but not of post-operative complications.

    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.

    Sterol O-Acyl Transferase 1 as a Prognostic Marker of Adrenocortical Carcinoma
    (2020) LACOMBE, Amanda Meneses Ferreira; SOARES, Ibere Cauduro; MARIANI, Beatriz Marinho de Paula; NISHI, Mirian Yumie; BEZERRA-NETO, Joao Evangelista; CHARCHAR, Helaine da Silva; BRONDANI, Vania Balderrama; TANNO, Fabio; SROUGI, Victor; CHAMBO, Jose Luiz; FREITAS, Ricardo Miguel Costa de; MENDONCA, Berenice Bilharinho; HOFF, Ana O.; ALMEIDA, Madson Q.; WEIGAND, Isabel; KROISS, Matthias; ZERBINI, Maria Claudia Nogueira; FRAGOSO, Maria Candida Barisson Villares
    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.
