Abstract We sought to assess the impact of neoadjuvant therapy on 30day mortality and morbidity using data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Chemotherapy and radiotherapy are both often indicated for treatment of cranial or systemic malignancy but can have significant adverse effects in the postsurgical setting. Data from 2006 to 2012 were obtained from the national ACS-NSQIP database. A total of 1044 patients were identified who obtained surgery for removal of metastatic brain tumors, of whom 127 received neoadjuvant chemotherapy and 65 neoadjuvant radiotherapy. Our primary outcome was 30day mortality and secondary outcomes were 30day surgical and medical morbidities. We selected previously reported preoperative variables to build a univariate and a multivariate model to determine preoperative characteristics most associated with neurosurgical mortality and morbidity. Our study found that neoadjuvant chemotherapy was associated with a 2.4-fold increase in the risk of 30day mortality compared to the patient cohort who did not receive chemotherapy ( p =0.023). Interestingly, there was no statistically significant increase in overall 30day surgical or medical morbidity for the chemotherapy group. Neoadjuvant radiotherapy was not associated with an increase in 30day morbidity or mortality. The significant increase in mortality associated with chemotherapy warrants further investigation, particularly to determine how to best personalize neoadjuvant chemotherapy treatment options to improve surgical outcomes. Neoadjuvant radiotherapy may be safer in terms of short-term postoperative morbidity and mortality.
