Testicular tumors in prepubescent patients

Academic Article

Abstract

  • © 2017 Elsevier Inc. Background/purpose: Pediatric testicular tumors are rare, constituting only 1% of all pediatric solid tumors. Single-institution studies addressing pediatric testicular tumors published to date have been limited in the number of patients. Methods: We utilized the National Cancer Data Base (1998–2012) to review all prepubescent patients (≤ 12 years old) with testicular neoplasms. Demographics, tumor characteristics, treatment modalities, and outcomes were abstracted. Results: A total of 479 patients were identified, with a median age of 3 years (IQR 0–4) at diagnosis. 67% of cases were diagnosed by 3 years of age. Yolk sac tumors were the most common histology (202 patients, 42.2%). Most tumors were diagnosed at a low stage. Resection was performed in 465 boys, with 75% having undergone radical orchiectomies. Chemotherapy was utilized in 28% of cases and radiotherapy in 7%. With mean follow-up of 5.6 years, mortality rate was 3%. No difference in mortality was noted based on histology or extent of surgical resection. Conclusions: This series of prepubertal testicular tumors is the largest yet reported and highlights the patient demographics, tumor characteristics, treatment modalities and outcomes for these tumors. Type of study: Prognosis study Level of evidence: II.
