Testicular tumors in the pediatric patient.

Testicular cancer is a rare malignancy that demonstrates variability in histopathologic features, treatment protocols, and outcomes based on a patient's age at presentation. In the pediatric population, puberty provides an important timestamp for evaluating and understanding the disease process. Prepubertal males, often designated as < 11 years of age, are more likely to present with benign disease. In contrast, the majority of post-pubertal testicular masses are malignant. Other factors, such as race/ethnicity, family history, and personal medical history can influence a patient's risk for malignancy as well. Serum tumor markers (STM) and histologic evaluation are key for diagnosis and for determining management. While normal STMs in a pre-pubertal patient likely qualify a patient for testis-sparing surgery, radical orchiectomy is the gold standard for post-pubertal patients, regardless of STM levels. Cross-sectional imaging is essential for staging and may be done before or after surgical intervention depending on the clinical scenario. Excellent survival outcomes are often achieved regardless of disease risk, with low-stage disease managed safely with surveillance. Surveillance usually consists of STM and imaging monitoring. If adjuvant therapy is indicated, a multi-disciplinary team approach is paramount. This approach should include following pediatric vs. adult protocols based of the patient's pubertal status in order to achieve optimal oncologic outcomes.
