Presentation and outcome in cancer patients with extensive spread to the brain.
BACKGROUND
Controversy exists around the preferred management of patients with brain metastases and limited survival expectation, e.g. because of extensive brain involvement. Few studies have focused on this particular group of patients.


RESULTS
A group of 24 patients with a large number of brain metastases, defined as 10 or more on computed tomography scans, who were managed with palliative whole-brain radiotherapy (WBRT), typically 30 Gy in 10 fractions, were analyzed. The median number of lesions was 14. The patient characteristics were comparable to those of studies in the general population with brain metastases, except for the fact that all patients had active sites of extracranial disease. Clinical benefit, imaging response and overall survival were lower than expected. Median survival, for example was 2 months. Trends towards better survival were found in patients with brain metastases detected at first cancer diagnosis (synchronous manifestation, treatment naïve) and those with better prognostic features according to the graded prognostic assessment (GPA) score.


CONCLUSIONS
The benefit of WBRT did not meet the expectations, suggesting that consideration should be given to best supportive care including corticosteroid administration, especially if a patient belongs to the lowest GPA class.
