Purpose : Fractionated stereotactic radiation therapy(FSRT) is a new modality that
combines the accurate focal dose delivery of stereotactic radiosurgery with the biological
advantages of conventional radiotherapy. We report our early experience using FSRT for
intracranial malignant tumor.
Materials and Methods : Between October 1995 and December 1996, 16 patients(9
males and 7 females aged between 10¡­64 years) with central nerve system malignancy
were treated using FSRT. Sixteen patients had the following diagnosis: 6 high-grade
gliomas, 1 pineoblastoma, 4 germinomas, 2 medulloblastomas, and 3 solitary brain
metastases. Using the Gill-Thomas-Cosman relocatable head frame and multiple
non-coplanar therapy, the daily dose of 2 Gy(3 Gy in metastasis) was irradiated at 85¡­
100% isodose surface.
Results : Although the follow-up period is relatively short(range; 2¡­18 months),
post-treatment clinical courses in 16 patients have been consistent with changes similar
to those found after conventional radiation therapy. No significant adverse effects were
observed in our neurological and radiological studies. Four out of 5 patients with high
grade glioma died from progressive disease, surviving from 7 to 17 months(median 14
months), but patients with pineoblastoma, germinoma and medulloblastoma showed no
evidence of recurrence. All patients with metastasis obtained a neurologic response, but
two among them died with extracranial progression and one die from multiple
intracranial metastasis.
In overall patient setup with scalp measurements, reproducibility was found to have
mean of 1.1¡¾0.6 mm from the baseline reading.
Conclusion : FSRT and relocatable stereotactic head frames were well tolerated with
minimal transient acute side effects. Subacute or late complications were not observed,
because the follow-up period was short. We expect that FSRT might be a good
indication for; recurrent disease with previous radiation therapy history, tumors of
relatively large volume, lesions adjacent to radiosensitive organs, and as a boost,
following conventional radiation therapy.
