Endodermal sinus tumor of the pineal region

Area of Science:

• Neuro-oncology
• Pediatric oncology

Background:

• Endodermal sinus tumors (ESTs) are rare germ cell tumors.
• Pineal region tumors are challenging due to their location.

Observation:

• This report details two cases of pineal region ESTs, reviewing 16 additional cases from the literature.
• These tumors predominantly affect males in their second decade.
• Diagnosis typically occurs within three months of nonspecific intracranial mass symptoms.

Findings:

• Neither surgical resection nor radiotherapy alone proved adequate for treating pineal region ESTs.
• The majority of patients succumbed to the disease within two years, often with widespread metastases.
• One patient achieved a five-year survival following combined surgical and radiotherapy treatment.

Implications:

• Aggressive, multimodal treatment including surgery and radiotherapy is crucial for managing pineal region ESTs.
• Early diagnosis and prompt intervention are vital for improving patient outcomes.
• Further research into optimal therapeutic strategies for these rare tumors is warranted.
