[Adult medulloblastomas: our experience]

Area of Science:

• Neuro-oncology
• Surgical oncology
• Radiation oncology

Context:

• Medulloblastomas are rare, malignant cerebellar tumors primarily affecting children.
• Adult medulloblastomas present unique treatment challenges and outcomes.
• This study details institutional experience with adult medulloblastoma management.

Purpose:

• To describe the clinical, radiological, and therapeutic outcomes of adult medulloblastomas.
• To evaluate the efficacy of multimodal treatment including surgery, radiotherapy, and chemotherapy.
• To identify prognostic factors and survival rates in adult medulloblastoma patients.

Summary:

• Retrospective analysis of 11 adult medulloblastoma patients treated between 1984-2010.
• Gross total surgical resection (72.7%) followed by craniospinal radiotherapy and chemotherapy (cisplatin and etoposide) was the standard treatment.
• Median follow-up of 35.2 months revealed a 36.4% relapse rate, managed with further surgery and chemotherapy. Mean survival was 100.3 months, with 5- and 8-year overall survival rates of 84% and 56% respectively.

Impact:

• Highlights the critical role of gross total surgical resection in adult medulloblastoma treatment.
• Emphasizes the importance of timely oncological therapy, particularly radiotherapy, post-surgery.
• Provides valuable data on survival outcomes and relapse patterns for this rare adult malignancy.
