Hypothesis
Should patients with confirmed single brain metastasis undergo surgical resection?
Conclusion
Surgical excision is recommended for patients with good performance status and a single brain metastasis, and postoperative whole-brain radiation therapy should be considered to reduce the risk of tumor recurrence.
Supporting Evidence
- Two of three randomized controlled trials reported a significant survival benefit for patients who underwent surgical resection compared to those who received whole-brain radiation therapy alone.
- Postoperative whole-brain radiation therapy significantly reduced the recurrence of tumors at the original site.
- Quality of life was improved for patients who received surgery plus whole-brain radiation therapy compared to those who received radiation alone.
Takeaway
If someone has one brain tumor from cancer, doctors suggest they might need surgery to remove it, and then they might also need radiation to help prevent it from coming back.
Methodology
A systematic review of evidence from randomized controlled trials, nonrandomized prospective studies, and retrospective studies was conducted using multiple medical databases.
Potential Biases
Potential referral bias and differences in primary tumor histologies may affect the results.
Limitations
The evidence is limited by the small size of the trials and the variability in patient characteristics.
Participant Demographics
Most patients had non-small-cell lung cancer, with others having breast, gastrointestinal, genitourinary, and melanoma.
