1. Radiotherapy: the core and cornerstone
Radiotherapy is pivotal for curing pure germinoma. Treatment may involve focal irradiation or whole-ventricle irradiation, and proton therapy can better spare normal brain tissue.
2. Chemotherapy: sensitive and necessary
Cisplatin-based combination regimens are standard first-line therapy, achieving rapid tumor shrinkage and enabling reduction of subsequent radiotherapy dose.
3. Surgery: diagnosis and decompression
Stereotactic biopsy is performed to obtain tissue for definitive diagnosis. In emergencies, ventriculostomy or shunt procedures can relieve acute obstructive hydrocephalus.
4. Salvage therapy
For recurrence, options include high-dose chemotherapy with stem cell transplantation, stereotactic radiotherapy, and investigational targeted agents.
5. Treatment for mixed or nongerminomatous components
Tumors containing malignant components require intensified chemotherapy, and gross total resection may be pursued when feasible to improve outcomes.
6. Endocrine replacement and long-term management
Lifelong hormone replacement is often required to manage diabetes insipidus and hypopituitarism, with dose adjustments under endocrinology supervision.
7. Multidisciplinary collaborative care
Neurosurgery, radiation oncology, endocrinology, and other specialists jointly develop individualized treatment and follow-up plans.
8. Supportive care and complication management
Actively manage adverse effects of chemoradiotherapy and establish long-term monitoring plans for cognitive sequelae and secondary malignancies.
9. Exploration of targeted and immunotherapy
Targeted approaches (e.g., against KIT alterations) are under investigation, and immunotherapy shows potential in recurrent or refractory cases.
10. Special considerations in pediatric patients
Priority is given to protecting growth, development, and cognition; chemotherapy-first strategies and radiotherapy dose reduction are often used.
11. Management of hydrocephalus
Endoscopic third ventriculostomy is preferred to relieve obstruction and avoid long-term complications associated with shunt devices.
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that germinoma can lead to profound long-term harm in adolescents, including blindness, lifelong endocrine dependence, and cognitive impairment. Once diagnosed, prompt initiation of standardized chemoradiotherapy-centered treatment is essential. Modern management prioritizes both efficacy and quality of life. With MDT-based planning, many patients can overcome the disease, but lifelong health management is required.
