Successful Treatment of Metastatic Brain Tumor with CyberKnife: A Case Report

Strategic Insights -

Researchers from the National Defense Medical Center in Taipei, Taiwan, have reported a dramatic success in treating a metastatic brain tumor using CyberKnife stereotactic radiosurgery. The case involved an adenocarcinoma of the lung that had spread to the brain, with a tumor diameter of approximately 3 cm. Despite previous treatments, including two craniotomies and whole brain radiation, the tumor recurred. However, after being treated with CyberKnife, a complete disappearance of the recurrent tumor was observed just 3 months later. This study highlights the potential of stereotactic radiosurgery in managing metastatic brain tumors, particularly in cases where previous treatments have failed.

Key Takeaways:

  • The metastatic brain tumor, measuring approximately 3 cm in diameter, was treated with CyberKnife stereotactic radiosurgery after previous treatments failed.
  • The tumor had recurred despite receiving two craniotomies and whole brain radiation.
  • A dramatic response was observed 3 months after radiosurgery, with the complete disappearance of the recurrent tumor.
  • Stereotactic radiosurgery plays a significant role in managing metastatic brain tumors, especially when previous treatments have failed.
  • The study suggests CyberKnife is a viable treatment option for metastatic brain tumors, even in large tumor sizes.
  • This case report highlights the importance of considering stereotactic radiosurgery as a treatment option for metastatic brain tumors with poor prognosis.

Statistics:

  • The metastatic brain tumor was approximately 3 cm in diameter.
  • The tumor recurred after being treated with two craniotomies and whole brain radiation.
  • A dramatic response was observed 3 months after CyberKnife radiosurgery, with the complete disappearance of the recurrent tumor.
  • The study suggests that stereotactic radiosurgery can achieve a complete response in tumors less than 1 cm^3(3).
  • The Kaohsiung Journal of Medical Sciences published this case report in 2010.
