Interpretation of the 5th edition WHO classification of adrenal cortical tumors / 中华病理学杂志

Non-neoplastic lesions were added in the 5th edition WHO classification of adrenal cortical tumor based on the recent update, including adrenal rests, adrenal cysts, congenital adrenal hyperplasia and adrenocortical nodular disease. A range of tumor concepts were updated or refined based on tumor cell origin, histopathology, oncology and molecular biology. The most significant nomenclature change in the field of adrenal cortical pathology involves the refined classification of adrenal cortical nodular disease, which now includes sporadic nodular adrenocortical disease, bilateral micronodular adrenal cortical disease, and bilateral macronodular adrenal cortical disease. The 5th edition WHO classification endorses the nomenclature of the HISTALDO classification to help the classification of aldosterone producing adrenal cortical lesions, which uses CYP11B2 immunohistochemistry to identify functional sites of aldosterone production. The 5th edition WHO classification does not change the Weiss and Lin-Weiss-Bisceglia histopathologic criteria for diagnosing adrenal cortical carcinomas, and underscores the diagnostic and prognostic impact of angioinvasion in these tumors. Reticulin algorithm and Helsinki scoring system were added to assist the differential diagnosis of adrenal cortical neoplasms in adults. Pediatric adrenal cortical neoplasms are assessed using the Wieneke system. The 5th edition WHO classification places an emphasis on an accurate assessment of tumor proliferation rate using both the mitotic count (mitoses per 10 mm2) and Ki-67 labeling index which play an essential role in the dynamic risk stratification of affected patients. This review highlights advances in knowledge of histological features, ancillary studies, and associated genetic findings that increase the understanding of the adrenal cortex pathologies in the 5th edition WHO classification.

Giant virilising adrenal cortical carcinoma

Androgen secreting adrenocortical carcinoma (ACC) is a very rare disease with a poor prognosis. Approximately 80% of tumors are functional, most commonly secreting glucocorticoids. We herewith report a case of a huge functional ACC of the right adrenal gland in a 33-year-old female who presented with complaints of hirsutism, amenorrhea and an abdominal lump. On abdominal examination a large lump was palpable in the right hypochondrium reaching up to the umbilicus. Contrast-enhance computed tomography (CECT) revealed a mass in the right suprarenal region. The tumor measured 29 cm × 20 cm × 12 cm and weighed 7.8 kg, the largest reported case of ACC in the world to the best of our knowledge.

Predictors of complication after adrenalectomy

ABSTRACT 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/m2, 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.

Primary malignant tumors of the adrenal glands

Malignancy must be considered in the management of adrenal lesions, including those incidentally identified on imaging studies. Adrenocortical carcinomas (ACCs) are rare tumors with an estimated annual incidence of 0.7-2 cases per year and a worldwide prevalence of 4-12 cases per million/year. However, a much higher incidence of these tumors (>15 times) has been demonstrated in south and southeastern Brazil. Most ACCs cause hypersecretion of steroids including glucocorticoids and androgens. ACC patients have a very poor prognosis with a 5-year overall survival (OS) below 30% in most series. Pheochromocytoma or paraganglioma (PPGL) is a metabolically active tumor originating from the chromaffin cells of the adrenal medulla. The incidence of PPGL is 0.2 to 0.9 cases per 100,000 individuals per year. Pheochromocytomas are present in approximately 4-7% of patients with adrenal incidentalomas. Classically, PPGL manifests as paroxysmal attacks of the following 4 symptoms: headaches, diaphoresis, palpitations, and severe hypertensive episodes. The diagnosis of malignant PPGL relies on the presence of local invasion or metastasis. In this review, we present the clinical and biochemical characteristics and pathogenesis of malignant primary lesions that affect the cortex and medulla of human adrenal glands.

Escore clínico-patológico para predizer o risco de metástases e recorrência local em pacientes com carcinoma cortical adrenal e papel do algoritmo da reticulina na distinção entre adenomas e carcinomas corticais adrenais / Clinicopathological score for predicting the risk of metastases and local recurrence in patients with adrenal cortical carcinoma and role of the reticulin algorithm in distinguishing between adrenal cortical adenomas and carcinomas

INTRODUÇÃO: o padrão-ouro para o diagnóstico histológico dos tumores corticais adrenais (TCAs) e sua diferenciação entre adenomas e carcinomas é o sistema de Weiss, cuja aplicação é limitada pela baixa reprodutibilidade de alguns dos critérios que o compõe. Recentemente foi proposto e validado um algoritmo diagnóstico para os TCAs baseado na integridade do arcabouço de reticulina e da membrana basal. Os carcinomas adrenais são tumores raros e apresentam prognóstico reservado, mesmo nos pacientes com doença aparentemente localizada. Além do estadiamento e da extensão da ressecção cirúrgica, outros dados foram reportados na literatura como tendo importância prognóstica, tais como idade ao diagnóstico, padrão funcional, tamanho tumoral, extensão local do tumor primário e alguns achados histológicos e imuno-histoquímicos, com destaque à taxa mitótica e ao índice de Ki-67. O sistema de Weiss, embora permita o diagnóstico diferencial entre adenomas e carcinomas, não foi testado completamente como uma ferramenta para distinguir os carcinomas com boa evolução clínica daqueles com desfecho desfavorável. OBJETIVOS: o presente estudo teve como objetivo primário construir um nomograma para estimar o risco de metástases e recorrência local em portadores de carcinoma adrenal, a partir de dados clínico-patológicos. O objetivo secundário foi avaliar o desempenho do algoritmo da reticulina no diagnóstico diferencial entre adenomas e carcinomas do córtex adrenal. MÉTODOS: para a construção do nomograma, foram analisados dados clínico-patológicos de 129 portadores de carcinomas adrenais atendidos no Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo entre 1976 e 2010. A avaliação do desempenho do algoritmo da reticulina para o diagnóstico histológico dos TCAs foi feita a partir do exame de 89 lâminas (45 adenomas e 44 carcinomas adrenais)...

INTRODUCTION: The gold standard for the histological diagnosis of adrenal cortical tumors (ACTs) and for the differentiation between adenomas and carcinomas is the Weiss system, whose application is limited by poor reproducibility of some of its criteria. Recently, a diagnostic algorithm for ACT diagnosis based on the integrity of the reticulin network and the basal membrane has been proposed and validated. Adrenal carcinomas are rare tumors and have a poor prognosis, even in patients with apparently localized disease. Besides tumor staging and extent of surgical resection, other data have been reported in the literature as having prognostic importance, such as age at diagnosis, the functional pattern, tumor size, local extension of the primary tumor and some histological and immunohistochemical findings, such as the mitotic rate and the Ki-67 index. The Weiss system, while allowing the differential diagnosis between adrenal cortical adenomas and carcinomas, has not been fully tested as a tool for distinguishing carcinomas with favorable clinical outcome from those with unfavorable outcome. OBJECTIVES: The primary objective of this study was to construct a nomogram for estimating the risk of metastasis and local recurrence in patients with adrenal cortical carcinoma, based on clinical and pathological data. The secondary objective was to evaluate the performance of the reticulina algorithm in the differential diagnosis between adenomas and carcinomas of the adrenal cortex. METHODS: For the construction of the nomogram, clinical and pathological data from 129 patients with adrenal cortical carcinomas treated at the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo between 1976 and 2010 were analyzed. The evaluation of the performance of the reticulin algorithm for the histological diagnosis of ACTs was made from the examination of 89 slides (45 adenomas and 44 adrenal carcinomas)...

Adrenal cortical carcinoma in Thailand: A review on the previous reported case.

Background: Adrenal cortical carcinoma (ACC) is an uncommon cancer. Materials and Methods: The author performed a literature review on the reports of ACC in Thailand in order to summarize the characteristics of this rare cancer among Thai patients. Results: According to this study, there have been at least seven reports in the literature of nine individual cases of ACC, of which none was lethal directly to ACC. Conclusions: Here, the ACC is sporadically reported in Thailand. The diagnosis of ACC is usually by detection adrenal mass using imaging technique and the confirmation for the nature of cancer is usually by histopathology. Nevertheless, among the Thai population, the prognostic outcome is usually good.

Carcinoma suprarrenal: [revisión] / Adrenocortical carcinoma: [review]

El carcinoma suprarrenal es una patología poco frecuente, con una incidencia anual estimada en 1-2 casos por millón de habitantes. Si bien se presenta a cualquier edad tiene una distribución bimodal, presentándose con mayor frecuencia antes de los 5 años y durante la cuarta y quinta décadas de vida. Tiene una leve tendencia a ser más frecuente en mujeres. Cerca del 60 por ciento de los casos se presentan como un tumor funcional asociado a un síndrome clínico reconocible. De estos los más frecuentes son el síndrome de Cushing y la virilización. El hiperaldosteronismo y la feminización son infrecuentes. Los pacientes con tumores no funcionales presentan un cuadro clínico producto del efecto de masa tumoral. Los estudios hormonales e imagenológicos son de vital importancia al momento de evaluar un paciente con sospecha de carcinoma suprarrenal. La adrenalectomía quirúrgica permanece como la única alternativa potencialmente curativa mientras que el Mitotano es el fármaco de elección en pacientes con tumores irresecables o enfermedad metastásica. El pronóstico del Carcinoma suprarrenal es malo, con una tasa de recurrencia de hasta el 80 por ciento y un promedio de sobrevida de 2 años.

Adrenocortical Carcinoma is an uncommon disease with an estimated incidence of 1-2 cases permillion people. Although it can occur at any age, it has a bimodal distribution, appearing more frequentlyin the first five years and during the fourth and fifth decades of life. It has a slight tendency to be more frequent in women. About 60 percent of cases are presented as a functional tumor associated with a recognizable clinical syndrome. Of these the most common are Cushing syndrome and virilization. The feminization and hyperaldosteronism are rare. Patients with a non-functional tumor present symptoms due to the tomoural mass effect. Hormonal and imaging studies are essential when assessing a patient with suspected adrenal carcinoma. Adrenalectomy remains as the only potentially curative treatment, whereas Mitotane is the drug of choice in patients with unresectable tumors or metastatic disease. The prognosis of adrenal carcinoma is poor, its rate of recurrence reaches 80 percent with an average survival of 2 years.

Carcinoma adrenocortical apresentando-se como massa abdominal / Adrenocortical carcinoma presenting as abdominal mass

O câncer adrenocortical (CAC) é um tumor raro com um prognóstico reservado. O CAC pode ser diagnosticado pela investigação de síndromes endócrinas, de sintomas devido ao crescimento tumoral ou de incidentaloma adrenal. A investigação hormonal demonstra na maioria dos CACs uma hipersecreção esteroidal, mas a característica dominante é uma co-secreção de cortisol e de andrógenos. A TC mostra um tumor heterogêneo e grande. Os tumores restritos à glândula adrenal têm uma evolução melhor do que tumores invasivos e metastáticos. A remoção completa do tumor é o tratamento de escolha. Nos pacientes com doença metastática ou progressiva, o tratamento com mitotano deve ser iniciado. Este relato de caso tem o intuito de demonstrar a importância do correto diagnóstico de lesões tumorais, pois têm grande influência no tratamento e prognóstico dos pacientes

Adrenocortical cancer (ACC) is a rare malign tumor with a poor prognosis. ACC can be diagnosed by the investigation of endocrine syndromes, signs and symptoms due to tumor growth or an adrenal incidentaloma. Hormonal investigations demonstrate in most ACC steroid oversecretion, but dominant characteristic being a co-secretion of cortisol and androgens. The CT shows a large heterogeneous tumor. Tumors localized to the adrenal gland have a better outcome than invasive and metastatic tumors. The complete tumor removal is the treatment of choice. In patients with metastatic or progressive disease, the treatment with mitotano must be initiated. This case has intention to demonstrate the importance of the correct diagnosis of tumors, therefore it has great influence in the treatment and prognosis of the patients
