Purpose: We reviewed clinical and laboratory findings in 6 male and 32 female patients with functional adrenocortical neoplasms, and compared pediatric and adult data.
Materials and methods: Hormonal measurements were performed by radioimmunoassay, histological analysis was based on Weiss criteria and staging was done according to previously established guidelines.
Results: Children had a higher incidence of virilization (72%), whereas in adults the predominant feature was Cushing's syndrome (60%). A high testosterone level was the most common finding in adults and children with virilization followed by high dehydroepiandrosterone sulfate, androstenedione and dehydroepiandrosterone levels. High 11-deoxycortisol levels were frequently associated with tumor recurrence. Cortisol suppression after dexamethasone was altered in 93% of patients with virilization and no clinical features, suggesting autonomous cortisol secretion.
Conclusions: No statistically significant relation was noted between tumor weight and prognosis but there was a negative correlation between patient age and prognosis since children had a more favorable followup than adults. Mixed features in both groups resulted in the worst prognosis. A Weiss criteria grade IV or greater correlated well with a poor prognosis in adults but not children, while staging was more reliable in children.
