Overview

While many studies have investigated the prognostic factors for patients undergoing surgical resection for primary brain tumors, decision-making for patients with brain metastasis (BM) is more complex because of their higher burden of comorbidities compared to those with primary brain tumors. In addition, although various prognostic indicators have been identified to predict prognosis in several types of cancer, such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), prognostic nutritional index (PNI), and systemic immune-inflammation index (SII), limited studies have yet determined which group of patients would yield beater survival outcome after surgical resection for BM. This study aimed to investigate the impact of patient and perioperative characteristics and prognostic indicators on survival outcome of patients undergoing surgical resection of BM.
