Abstract

Objective: Evaluation of outcomes of surgical treatment for sacrococcygeal germ cell tumors in children. Materials and methods: This retrospective descriptive case series includes all pediatric patients under 16 years old diagnosed with sacrococcygeal germ cell tumors (GCTs) and treated surgically at Children's Hospital 2 from January 1, 2018 to December 31, 2024. Results: We recorded 34 patients meeting the inclusion criteria. All patients underwent complete tumor resection along with partial coccygectomy, primarily via a retrorectal surgery (91,2%). Tumor rupture was the most frequent intraoperative complication (23,5%). Lymph node biopsy was performed in 2 cases (5,9%). The most frequent postoperative complication was surgical site infection, occurring in 9 cases (26,5%), whereas 67,6% of patients experienced no operative complications. One patient (2,9%) required a second surgery due to tumor recurrence. Stage I and low-risk tumors accounted for 94,1% of cases. 5 patients (14,7%) received surgery combined chemotherapy. All patients undergoing surgery alone achieved complete response. The study reported 1 case of recurrence (2,9%) and no cases of mortality. Conclusion: Surgery is the main treatment approach with low rates of complications and recurrence.
