PATIENTS AND METHODS: We performed a retrospective review of patients < 18 years with ACC treated from 2012 to 2022 at 22 institutions participating in the Pediatric Surgical Oncology Research Collaborative. Data collected included demographics, clinical presentation, genetic predisposition, tumor characteristics, surgical approach, adjuvant treatment, and survival outcome. Survival probabilities were estimated with Kaplan-Meier methods.
RESULTS: In all, 69 patients were included (median age: 8.4 years; 58% female), and 28% had Li-Fraumeni syndrome. At diagnosis, 36% had Stage IV disease and 28% had Stage I disease. A total of 55 (83%) patients underwent open adrenalectomy, and 11 (17%) underwent MIS. MIS approaches were employed for significantly smaller tumors (median: 4.4 cm, 38 g) compared with open cases (median: 9.6 cm, 246 g; p < 0.001), and none had tumor spillage (versus 22% in open cases; p = 0.087). Lymph node sampling was performed in 44% of open cases (mean yield: 2.96); no lymph nodes were sampled in MIS cases (p = 0.008). The 5 year overall survival (OS) for the entire cohort was 65.9%, and 5-year event-free survival (EFS) was 54.1%. Patients without metastases had significantly better survival than those with more than five metastatic lesions (5 year OS: 84.5% versus 11.9%; p < 0.001).
CONCLUSIONS: Complete surgical resection remains paramount for cure in children with ACC. Despite aggressive attempts at tumor clearance, outcomes in children with metastatic disease remain poor. Nodal dissection remains infrequently and incompletely performed, limiting conclusions on impact.
