After MDT, 56 patients (53.8% ) was found to have intracranial "diagnosis upgrade". In the matched population, patients in the MDT group were recorded a higher proportion of meningeal metastases (14.4% vs. 4.8%, P = 0.02), symptomatic tumour progression (11.5% vs. 5.8%, P =0.04) and an increased number of occurrences of brain metastases(BM) progression (P<0.05). Attending MDT was an independent factor associated with ≥2 courses of intracranial radiotherapy(RT) (odds ratio (OR) 5.4, 95% confidence interval(CI): 2.7-10.9, P < 0.001), novel RT technique use(7.0, 95% CI 3.5-14.0, P<0.001), prospective clinical research (OR 5.7, 95% CI 2.4-13.4, P<0.001).Patients with complex conditions are often referred for MDT discussions. An MDT may improve the qualities of intracranial RT and systemic therapy, resulting in benefits of overall survival for breast patients after BM. This encourages that treatment recommendations for patients with BMBC should be discussed within an MDT.
