Primary intracranial rhabdomyosarcoma.

Area of Science:

• Pediatric Oncology
• Neuro-oncology
• Rhabdomyosarcoma Research

Background:

• Primary intracranial rhabdomyosarcoma is an exceptionally rare pediatric brain tumor.
• Historically, outcomes for this malignancy have been poor, with limited reported cases.

Purpose of the Study:

• To report on five pediatric cases of intracranial rhabdomyosarcoma treated with a multimodal approach.
• To highlight the importance of advanced diagnostic techniques and aggressive therapy for this rare tumor.

Main Methods:

• Multimodal treatment including surgical resection, craniospinal irradiation, and intravenous-intrathecal chemotherapy.
• Utilized electron microscopy and immunohistochemistry for definitive pathological diagnosis.
• Followed patients for long-term survival outcomes.

Main Results:

• Two patients achieved long-term survival (21 and 67 months), with one representing the longest reported survival.
• Tumor recurrence led to death in two patients.
• One patient died due to pulmonary embolism; posterior fossa involvement was common at diagnosis.

Conclusions:

• Aggressive, multimodal therapy can lead to improved survival in pediatric intracranial rhabdomyosarcoma.
• Accurate diagnosis using advanced techniques is vital for timely and effective treatment.
• This study suggests a potential reevaluation of the prognosis for this rare brain malignancy.
