Comparative StudyIntracranial control and radiographic changes with adjuvant radiation therapy for resected brain metastases: whole brain radiotherapy versus stereotactic radiosurgery alone.
The aim of this study was to compare outcomes of postoperative whole brain radiation therapy (WBRT) to stereotactic radiosurgery (SRS) alone in patients with resected brain metastases (BM). We reviewed records of patients who underwent surgical resection of BM followed by WBRT or SRS alone between 2003 and 2013. Local control (LC) of the treated resected cavity, distant brain control (DBC), leptomeningeal disease (LMD), overall survival (OS), and radiographic leukoencephalopathy rates were estimated by the Kaplan-Meier method. ⋯ Compared with WBRT for patients with resected BM, SRS alone demonstrated similar LC, higher rates of LMD and inferior DBC, after controlling for the number of BM. However, OS was similar between groups. The results of ongoing clinical trials are needed to confirm these findings.

Risk factors for venous thromboembolism in patients undergoing craniotomy for neoplastic disease.
Patients undergoing neurosurgical procedures for neoplasia have historically been considered at higher risk for developing venous thromboembolism (VTE). We sought to identify risk factors associated with VTE in patients undergoing craniotomy for tumor resection. We reviewed a national surgical quality database (American College of Surgeons National Surgical Quality Improvement Project, ACS-NSQIP, http://site.acsnsqip.org/ ). ⋯ Age > 60, OR time > 4 h, UTI, and septic shock were significantly associated with VTE in multivariate analysis. Patients undergoing craniotomy for neoplasm are at increased risk of VTE. This risk appears to be modified by pre-operative medical comorbidities, longer operative time, and post-operative complications.

Gamma knife radiosurgery for the treatment of gynecologic malignancies metastasizing to the brain: clinical article.
Gynecologic malignancies represent some of the commonest causes of cancer in the female population. Despite their overall high prevalence, gynecologic malignancies have seldom been reported to metastasize to the brain. The incidence of gynecologic cancers spreading to the brain has been rising, and the optimal management of these patients is not well defined. ⋯ Patients with ovarian cancer had prolonged median survival following GKRS compared to patients with endometrial cancer (22.3 vs 8.3 months, p = 0.02). The patient with cervical cancer survived 8 months following her GKRS in the setting of metastatic brain tumor progression, whereas the patient with leiomyosarcoma passed away within several weeks of treatment secondary to disseminated extracranial primary disease. GKRS is a safe and effective means of achieving intracranial tumor control for patients with gynecologic cancer that has spread to the brain.
