To determine overall survival (OS) and independent prognostic factors in patients with brain metastases (BM) from breast cancer treated by whole brain radiotherapy (WBR). ⋯ Brain metastases from breast cancer remain associated with very poor prognosis and there is a need for better treatment procedures. If confirmed in predictive models, the identification of prognostic subgroups, based on KPS and lymphopenia, among patients with BM from breast cancer would help physicians select patients for future clinical trials.

Bone metastases causing neuropathic pain (NBP) have traditionally been treated with fractionated radiotherapy (RT). A recently reported randomised Trans-Tasman Radiation Oncology Group trial (TROG 96.05) supports this approach in many cases [Roos DE, Turner SL, O'Brien PC et al. Randomised trial of 8 Gy in 1 versus 20 Gy in 5 fractions of radiotherapy for neuropathic pain due to bone metastases (Trans-Tasman Radiation Oncology Group, TROG 96.05). Radiother Oncol 2005;75:54-63]. This study sought to compare costs to the Australian health-care system for patients receiving 1 versus 5 fractions for NBP. ⋯ Clinical outcomes are paramount in choice of fractionation scheme but are optimally considered in the light of economic implications. Overall cost differences between fractionation schedules may vary greatly from those incurred by the RT treatment centre alone. Ideally, such economic evaluations should be planned at the outset of a trial.
