Adrenocortical carcinoma in children and adults: Two decades experience in a single institution

Exceptional Clinical Response to Surgery in Somalian Child Affected by Hyper Secretive Adrenal Cortical Carcinoma

Adrenocortical cancers in childhood are very rare tumors. They are categorized as functional (hormone-secreting) or silent and as either benign or malignant. They have a bimodal distribution. Although in most adults they are non-functional, in the pediatric age group they may present as hormonal active or as an active tumor presenting with either virilizing forms or Cushing’s syndrome or both sometimes. In children, due to the rapid development of symptoms, they come to attention early. However, if not diagnosed and treated early, they can develop into serious medical conditions. We present here a 6-year-old girl complaining of voice changes (deepening), extremely overweight, excessive hair growth over her body, and clitoromegaly for one year. Abdominal ultrasound and computed tomography revealed a well-defined adrenal mass with a slightly heterogeneous appearance and heterogeneous-contrast enhancement containing some necrotic areas. The patient was discharged one week after unilateral right adrenalectomy in good condition, and oral medications were given along with high-dose corticosteroid medications, which were reduced gradually. All the symptoms disappeared 6 months after the operation.

Surgical outcomes and survival of adrenocortical carcinoma between children and adults

INTRODUCTION

Adrenocortical carcinoma (ACC) is associated with poor outcomes. We compared surgical outcomes between children and adult; and identified factors independently associated with survival.

METHODS

Using the National Cancer Database, children and adults with ACC who underwent surgery between 2004 and 2016 were identified. We compared outcomes and survival between groups. Cox regression analysis was performed to identify predictors of survival.

RESULTS

Of 2553 patients, 2.8% were children. A higher proportion of children were Hispanic (19.1%vs.6.6%) and covered by government insurance (45.1%vs.35.8%) than adults. More pediatric patients received lymphadenectomy and chemotherapy than adults. Pediatric patients had better survival at 1 -(91.4%; 95%CI: 81.2%-96.0% vs.79.6%; 95%CI: 77.9%-81.1%) and 5-years (60.6%; 95%CI:47.5%-71.3% vs.44.9%; 95%CI 42.7%- 47.0) (p = 0.0016). Age≥18 (HR: 2.21(1.50-3.27)), metastatic disease at diagnosis (HR: 3.51(3.04-4.04)), and receipt of lymphadenectomy (HR: 1.30(1.14-1.48)) were independently associated with worse survival.

CONCLUSIONS

Children with ACC had better survival than adults. Factors independently associated with worse survival included older age, metastatic disease, and receipt of lymph node surgery.

Adrenocortical Carcinoma in Childhood: A Systematic Review

Adrenocortical tumors are rare in children. This systematic review summarizes the published evidence on pediatric adrenocortical carcinoma (ACC) to provide a basis for a better understanding of the disease, investigate new molecular biomarkers and therapeutic targets, and define which patients may benefit from a more aggressive therapeutic approach. We included 137 studies with 3680 ACC patients (~65% female) in our analysis. We found no randomized controlled trials, so this review mainly reflects retrospective data. Due to a specific mutation in the TP53 gene in ~80% of Brazilian patients, that cohort was analyzed separately from series from other countries. Hormone analysis was described in 2569 of the 2874 patients (89%). Most patients were diagnosed with localized disease, whereas 23% had metastasis at primary diagnosis. Only 72% of the patients achieved complete resection. In 334 children (23%), recurrent disease was reported: 81%-local recurrence, 19% (n = 65)-distant metastases at relapse. Patients < 4 years old had a different distribution of tumor stages and hormone activity and better overall survival (p < 0.001). Although therapeutic approaches are typically multimodal, no consensus is available on effective standard treatments for advanced ACC. Thus, knowledge regarding pediatric ACC is still scarce and international prospective studies are needed to implement standardized clinical stratifications and risk-adapted therapeutic strategies.

Adrenocortical Carcinoma in a 6-Month-Old Infant

Adrenocortical carcinoma (ACC) is a rare malignant tumor arising from the adrenal cortex and it is even rarer in infancy. These tumors are usually hormonally active. We report a case of ACC in a 6-month-old infant who was brought by her mother with complaints of hirsutism and abnormally looking genitalia. Serum 17-alpha-hydroxyprogesterone and serum cortisol levels were raised. Subsequently, imaging studies revealed a large well-circumscribed soft-tissue mass in the right suprarenal region. The tumor was excised, and on histopathology in conjunction with immunohistochemistry, a diagnosis of ACC was given. Only four other cases of ACC have been reported till date in the literature, with an age of 6 months or younger. Hereby, we present a case of ACC in a young infant.

The outcome of childhood adrenocortical carcinoma in Egypt: A model from developing countries

Adrenocortical carcinoma (ACC) is a rare, aggressive endocrine neoplasm. Complete surgical resection is the single most important treatment. Most available information has been learned from experience with its more frequent adult counterpart. In this study, we assessed the features and survival outcome of patients with ACC at Children's Cancer Hospital Egypt (CCHE). Patients diagnosed at CCHE between July 2007 and November 2016 were followed up on until November 2018. Patients with stages I and II were operated upon, while stages III and IV had received combinations of doxorubicin, etoposide, platinol, and mitotane (DEPM) beside the attempt to conduct surgery when feasible. Data belonging to 18 patients (7 men and 11 women) were analyzed; median age at diagnosis was 48.5 months. Sixteen patients had presented with secreting tumors. Six patients were diagnosed with stage I disease; four with stage II; three with stage III; and five with stage IV carcinoma. By the end of this study, 10 patients have survived; five-year overall survival of 66.3%. Surviving patients were all of stage I or II diseases and were all in remission. Seven patients who did not survive died due to tumor progression, while one patient died after chemotherapy. The prognosis of ACC is essentially dependent on a successful complete resection of the tumor and thus on the initial tumor stage. The mitotane and DEP protocols may help control tumor growth in the advanced stages for only short periods. Key pointsInitial stage and resectability are the main indicators of outcomes in adrenocortical carcinoma.Chemotherapeutic agents used in developed countries did not achieve the same outcomes.Further molecular-pharmacology differentiation is needed for various ethnic populations.
