Objective:

To determine the efficacy of combining minimally invasive keyhole craniotomy (MIKC) and Cs-131 brachytherapy for local control, toxicity, and radiation necrosis in patients with newly diagnosed brain oligometastases, specifically focusing on the impact on survival and quality of life.

Key Findings:
  • Cs-131 SBT demonstrated lower rates of radiation necrosis compared to I-125, with statistical significance.
  • MIKC resulted in reduced trauma and faster recovery compared to conventional techniques, supported by recovery time metrics.
  • Combination of MIKC and Cs-131 SBT showed potential for effective local tumor control and improved functional outcomes, with specific data on survival rates.
Interpretation:

The study suggests that the combination of MIKC and Cs-131 brachytherapy may enhance treatment outcomes for patients with newly diagnosed brain oligometastases, particularly in terms of local control and reduced complications.

Limitations:
  • Small sample size of 21 patients limits generalizability and may introduce bias.
  • Focus on newly diagnosed tumors may not reflect outcomes in recurrent cases.
  • Short follow-up period may not capture long-term effects, necessitating further research.
Conclusion:

Combining minimally invasive keyhole craniotomy with Cs-131 brachytherapy appears promising for treating brain oligometastases, warranting further investigation in larger cohorts to validate these findings.
