Abstract
Introduction: Intracranial germinoma has a favorable prognosis with modern therapies, but the long-term outcome of cerebrospinal fluid (CSF) diversion for its associated hydrocephalus has been rarely focused on. Purpose: To evaluate the long-term success of CSF diversion methods—endoscopic third ventriculostomy (ETV) versus ventriculoperitoneal (VP) shunt—in intracranial germinoma patients. Methods: Only pure intracranial germinomas with obstructive hydrocephalus and a minimum follow-up duration of 24 months were retrospectively reviewed. Their demographics, as well as pre-and postoperative data, were recorded. Patients were stratified into the ETV and the non-ETV groups and subsequently compared to determine the longevity and morbidity related to the procedures. Factors associated with the failure of CSF diversion were examined. Results: From 1993 to 2022, eighty-three pathologically confirmed intracranial germinomas were identified. Excluding four cases of mixed pathology, eight with incomplete data, and two with insufficient follow-up, we enrolled 69 eligible patients for analysis. Among them, forty-three cases with obstructive hydrocephalus were classified into the ETV (n = 22) and non-ETV (n = 21) groups. No intraoperative or immediate postoperative complications occurred. With a median follow-up of 101 months (IQR 77.75–139.75), the ETV group had no failures. In the non-ETV cohort (median follow-up 144 months (IQR 97–210)), two VP shunt cases (9.5%) required revision due to blockage, and two patients (9.5%) experienced transient over-drainage. These 4 patients were without long-term difficulty despite short-term cumbersome events. No significant factors predicting CSF diversion failure were identified. To date, all 43 patients are alive without metastases, maintaining a good quality of life. Conclusion: This study highlights ETV as a preferred CSF diversion method in pure intracranial germinoma, achieving 100% success without morbidity. Apart from simultaneous biopsy, avoiding a separate operation, this approach eliminates shunt-related complications, ensuring long-term quality of life in patients with extraordinary prognoses from modern chemo- and radiotherapy.
