Abstract
Background The aim of this study was to review clinical features of adolescent malignant germ cell tumors (MGCTs) in Beijing and analyze the peculiar characteristics of this age group. Methods Clinical characteristics, pathological presentations, and survival outcomes of 34 patients were analyzed retrospectively. Results Of 34 patients, 12 girls and 22 boys, 18 (52.9%) had an extra-cranial tumor, including one testicular tumor, five ovarian tumors, one sacrococcygeal tumor, and 11 mediastinal tumors. Histologically, we found immature teratomas (n = 6), yolk sac tumors (n = 5), mixed malignant tumors (n = 5), an embryonic carcinoma (n = 1), and seminoma (n = 1). Three-year event-free survival (EFS) and overall survival (OS) were 48.8% and 62.9%, respectively. Another 16 (47.1%) patients had an intracranial tumor, including nine in the pineal region, five in the suprasellar region, one in basal ganglia, and one in cerebellopontine. All patients had localized disease and an excellent outcome with 3-year EFS and OS of 93.7% and 100%, respectively. Conclusions Adolescent MGCTs are rare with a strong dependence on gender, and the mediastina and pineal region are the most common tumor locations. The prognosis is promising compared with that of other adolescent tumors and MGCTs in other age groups. MGCTs in mediastina have a tendency to companion with other hematological malignancies, and the prognosis is extremely poor in these patients.
