Summary
Interstitial brachytherapy using Iodine-125 seeds offers a promising radiotherapy option for gliomas. This technique, applied stereotactically, delivers targeted radiation doses to brain tumors, complementing conventional treatments.
Area of Science:
- Neurosurgery
- Radiation Oncology
- Oncology
Background:
- Radiotherapy is a key adjuvant treatment for gliomas post-surgery.
- Conventional teletherapy has limitations, making interstitial radiation a viable alternative.
- Brachytherapy presents a method for targeted radiation delivery in brain tumors.
Purpose of the Study:
- To present the principles and application of brachytherapy for glioma treatment.
- To evaluate the feasibility and dose delivery of interstitial brachytherapy in glioma patients.
Main Methods:
- Stereotactic implantation of Iodine-125 (I125) radioactive sources into 10 glioma cases.
- Application of closed radioactive sources for a duration sufficient to deliver therapeutic doses.
- Combination therapy with teleradiotherapy in some patients.
Main Results:
- Tumor border doses ranged from 812 to 4560 cGy, with a mean of 2064 cGy.
- Five patients received an additional 6000 cGy via teleradiotherapy.
- Demonstrated practical application of stereotactic brachytherapy for gliomas.
Conclusions:
- Stereotactic brachytherapy with I125 is a feasible supplementary treatment for gliomas.
- The technique allows for targeted radiation delivery to brain tumors.
- Brachytherapy offers an alternative to overcome limitations of traditional radiotherapy for gliomas.
