Single brain metastases: surgery plus radiation or radiation alone

Area of Science:

• Oncology
• Neurosurgery
• Radiation Oncology

Background:

• Non-small-cell lung cancer frequently metastasizes to the brain.
• Single brain metastases present unique treatment challenges.
• Optimal management strategies for these patients are crucial.

Purpose of the Study:

• To evaluate the efficacy of surgical intervention combined with radiation therapy versus radiation therapy alone for single brain metastases from non-small-cell lung cancer.
• To compare survival rates, local recurrence, and neurologically related deaths between treatment groups.

Main Methods:

• Retrospective review of 86 patients treated between 1978-1982 for single brain metastases from non-small-cell lung cancer.
• Matched cohort analysis comparing 43 surgically treated patients (including combined modality) with 43 patients treated with radiation therapy alone.

Main Results:

• Combined surgery and radiation therapy group demonstrated significantly longer survival (19 months) compared to radiation therapy alone (9 months).
• The radiation therapy-alone group exhibited significantly higher rates of local recurrence and neurologically related deaths.
• Surgical intervention contributed to improved outcomes by reducing recurrence and neurological complications.

Conclusions:

• Combined surgical and radiation therapy is a superior treatment strategy for single brain metastases in non-small-cell lung cancer.
• This multimodal approach leads to improved survival and reduced treatment-related morbidity.
• Surgical resection followed by adjuvant radiation therapy should be considered for eligible patients.
