Its treatment follows the principles developed for adults; pediatric-specific studies are scarce. <\/jats:p><\/jats:sec><jats:sec><jats:title>PATIENTS AND METHODS<\/jats:title><jats:p> Prospective single-arm risk-stratified interventional study. Study objectives were (1) to describe the outcome of patients with stage I ACC treated with adrenalectomy alone; (2) to describe the outcome of stage II patients (completely resected &gt; 200 cc or &gt; 100 g) treated with adrenalectomy and retroperitoneal lymph node dissection; and (3) to describe the outcome of patients with stage III or IV treated with mitotane and chemotherapy. <\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p> Between September 2006 and May 2013, 78 patients (77 eligible, 51 females) were enrolled. The 5-year event-free survival estimates for stages I (24 patients), II (15 patients), III (24 patients), and IV (14 patients) were 86.2%, 53.3%, 81%, and 7.1%, respectively. The corresponding 5-year overall survival estimates were 95.2%, 78.8%, 94.7%, and 15.6%, respectively. On univariate analysis, age, stage, presence of virilization, Cushing syndrome, or hypertension, germline TP53 status, and presence of a somatic ATRX mutation were associated with outcome. On multivariable analysis, only stage and age were significantly associated with outcome. The probabilities of mitotane and chemotherapy feasibility events were 10.5% and 31.6%, respectively. <\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p> Outcome for children with stage I ACC is excellent with surgery. Outcome for patients with stage II disease is inferior despite retroperitoneal lymph node dissection. Patients with stage III ACC have an excellent outcome combining surgery and chemotherapy. Patients with stage IV ACC are older and have a poor outcome; new treatments should be explored for this high-risk group. The combination of mitotane and chemotherapy as prescribed in ARAR0332 resulted in significant toxicity; one third of patients with advanced disease could not complete the scheduled treatment. <\/jats:p><\/jats:sec>","DOI":"10.1200\/jco.20.02871","type":"journal-article","created":{"date-parts":[[2021,4,6]],"date-time":"2021-04-06T19:59:20Z","timestamp":1617739160000},"page":"2463-2473","update-policy":"https:\/\/doi.org\/10.1200\/crossmark","source":"Crossref","is-referenced-by-count":88,"title":["Treatment of Pediatric Adrenocortical Carcinoma With Surgery, Retroperitoneal Lymph Node Dissection, and Chemotherapy: The Children's Oncology Group ARAR0332 Protocol"],"prefix":"10.1200","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2360-8946","authenticated-orcid":false,"given":"Carlos","family":"Rodriguez-Galindo","sequence":"first","affiliation":[{"name":"Department of Oncology, St Jude Children's Research Hospital, Memphis, TN"},{"name":"Department of Global Pediatric Medicine, St Jude Children's Research Hospital, Memphis, TN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark D.","family":"Krailo","sequence":"additional","affiliation":[{"name":"Statistics and Data Center, Children's Oncology Group, Monrovia, CA"},{"name":"Department of Preventive Medicine, University of Southern California, Los Angeles, CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5567-000X","authenticated-orcid":false,"given":"Emilia M.","family":"Pinto","sequence":"additional","affiliation":[{"name":"Department of Pathology, St Jude Children's Research Hospital, Memphis, TN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2883-0957","authenticated-orcid":false,"given":"Farzana","family":"Pashankar","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Yale University School of Medicine, New Haven, CT"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher B.","family":"Weldon","sequence":"additional","affiliation":[{"name":"Department of Surgery, Boston Children's Hospital, Boston, MA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Huang","sequence":"additional","affiliation":[{"name":"Statistics and Data Center, Children's Oncology Group, Monrovia, CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eliana M.","family":"Caran","sequence":"additional","affiliation":[{"name":"Department of Oncology, Instituto de Oncologia Pediatrica, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Hicks","sequence":"additional","affiliation":[{"name":"Department of Pathology, Texas Children's Hospital, Houston, TX"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2888-443X","authenticated-orcid":false,"given":"M.
