Age = age in years at time of brain metastasis diagnosis; male = percentage of male patients of the patient cohort; ECM = percentage of patients diagnosed with extracranial metastases; BM > 1 = percentage of patients diagnosed with more than one brain metastases; resection = percentage of patients that received surgical resection of brain metastases; OS = median survival of all patient diagnosed with brain metastases within the respective study; OS resection = median survival of the patients who received surgical resection of brain metastases; n/a = data not available. All sources are parenchymal brain metastasis cases, not leptomeningeal carcinomas.
