Summary
Radiotherapy for pineal tumors significantly improves survival rates, especially for germinoma. Doses between 1,500 and 1,699 rets, with or without decompression, enhance prognosis for these rare brain tumors.
Area of Science:
- Neuro-oncology
- Radiation Oncology
Background:
- Pineal tumors are rare intracranial neoplasms requiring specialized treatment strategies.
- Radiotherapy is a primary modality for managing pineal region tumors, but optimal techniques and outcomes require further elucidation.
Purpose of the Study:
- To review case histories of patients treated with radiotherapy for pineal tumors.
- To assess treatment indications, radiotherapy techniques, and survival outcomes.
- To identify factors influencing prognosis in pineal tumor patients.
Main Methods:
- Retrospective review of 58 patients with pineal tumors who received radiotherapy.
- Analysis of survival rates based on tumor histology and treatment parameters.
- Evaluation of radiotherapy doses, use of decompression, field size, and CT scan changes.
Main Results:
- Overall five-year and 10-year survival rates were 61% and 58%, respectively.
- Five-year survival was 85% for germinoma, 69% for histologically unconfirmed tumors, and 0% for glioma and teratoma.
- Radiotherapy doses of 1,500-1,699 rets, with or without decompression, improved prognosis.
Conclusions:
- Radiotherapy is effective for pineal tumors, with significant survival benefits observed.
- Germinoma histology is associated with a favorable prognosis following radiotherapy.
- Specific radiotherapy doses and surgical interventions like decompression appear crucial for improving outcomes in pineal tumor management.
