Adrenocortical tumor (ACT) is a rare disease with an annual worldwide incidence of 0.3-0.38/million children below 15 years old, and Brazilian population presents the highest incidence because of germline mutation in the TP53. Pediatric ACT is associated with virilizing features and hypercortisolism in most cases. Malignancy is defined when local invasion or metastasis is found, and it is associated with a poor prognosis. However, the correct and early diagnosis and treatment may impact on overall and disease-free survival.
A complete understanding of the disease and its singularities facilitates the assistance to the pediatric patient with ACT. The new insights about adrenal tumorigenesis have provided a better understanding of this disease. In this scenario, the era of molecular studies is leading to the refinement of the taxonomy, and it is offering the opportunity to discover new biomarkers and pathways of tumorigenesis, beyond the knowing β-catenin, Insulin-like growth factor-II/IGF-IR, and the p53/Rb signaling.
The rarity of this disease makes it a real challenge. Here, we present a review focusing on clinical practice. A methodic approach aiming to clarify the diagnosis and a follow-up are suggested to guide physicians in the assistance of pediatrics patients, improving the prognosis.
肾上腺皮质肿瘤(adrenocortical tumor,ACT)是一种罕见疾病,全球每年 15 岁以下儿童的发病率为 0.3-0.38/百万,巴西人群由于 TP53 种系突变而发病率最高。儿科 ACT 大多数情况下与男性化特征和皮质醇增多症相关。局部侵犯或转移时定义为恶性肿瘤,预后不良。然而,正确和早期的诊断和治疗可能会影响整体和无病生存率。
全面了解该疾病及其特征有助于为 ACT 患儿提供帮助。对肾上腺肿瘤发生的新认识使我们对这种疾病有了更好的了解。在此背景下,分子研究时代正在促使分类法的精细化,并提供了发现新的生物标志物和肿瘤发生途径的机会,除了已知的β-连环蛋白、胰岛素样生长因子-II/IGF-IR 和 p53/Rb 信号通路之外。
这种疾病的罕见性使其成为一个真正的挑战。本文就临床实践进行综述。建议采用一种方法学方法来明确诊断和进行随访,以指导医生为儿科患者提供帮助,改善预后。
