Summary
Radiotherapy improved functional capacity in 32 of 64 patients with brain metastases, though survival rates were unaffected. Melanoma metastases showed radioresistance to this treatment.
Area of Science:
- Neurology
- Oncology
- Radiotherapy
Background:
- Intracranial metastases significantly impact patient functional capacity.
- Radiotherapy is a common treatment modality for brain metastases.
Purpose of the Study:
- To evaluate the efficacy of high-energy radiotherapy in improving functional capacity in patients with intracranial metastases.
- To assess the impact of radiotherapy on neurological status and survival rates in patients with brain metastases.
Main Methods:
- A series of 64 patients with intracranial metastases received whole-brain radiotherapy (telecobalt therapy) with doses of 1.5-2 Gy daily to a total of 30-40 Gy.
- Patients were assessed before and after treatment using Order's neurological classification to evaluate changes in intellectual awareness and physical abilities.
- Primary tumor sites included breast (32), lung (24), melanoma (5), bone (1), and unknown (2).
Main Results:
- Overall, 32 patients showed improved functional capacity, 21 remained stable, and 11 experienced worsening neurological status.
- Cerebral metastases originating from melanoma demonstrated radioresistance to the radiotherapy regimen.
- The study observed no significant influence of the radiotherapy treatment on patient survival rates.
Conclusions:
- High-energy radiotherapy can improve functional capacity in a significant portion of patients with intracranial metastases.
- Melanoma brain metastases are less responsive to conventional radiotherapy.
- Radiotherapy for intracranial metastases, in this cohort, did not alter overall survival but improved quality of life for some patients.
