Background: Patients with brain metastases (BrMs) from esophageal cancer have poor prognosis, the incidence of which is expected to rise due to improved survival from the primary tumor and increased neuroimaging. We aimed to identify patient and esophageal cancer characteristics associated with shorter survival in patients with BrMs and, secondly, to compare the prognosis of patients with HER2 overexpression., Methods: We retrospectively reviewed patients with BrMs from esophageal cancer at a single institution from 2008-2021. We collected patient demographics, primary tumor and BrM characteristics, and treatment. Our primary outcome was median survival from the time of BrM., Results: The median age at primary diagnosis was 66.5 years and 86% were male. Of the 49 patients, 71% had adenocarcinoma, 20% squamous cell carcinoma and 8% other. In this group, 71% of patients presented with stage III or IV disease, including 16% with synchronous primary metastatis and BrM. The median time to BrM was 10.1 months (interquartile range 1.7-22.8) and the median survival from BrM was 8.4 months (95% CI 4.8-16.8 months). On multivariable analysis, treatment with stereotactic radiosurgery (hazard ratio [HR] = 0.19; P = 0.04), surgical resection (HR 0.24; P = 0.03), and immunotherapy (HR 0.19; P = 0.04) were associated with increased survival while Karnofsky Performance Status (KPS) ≤70 (HR = 13.2; P < 0.001) was associated with decreased survival. HER2 overexpression was found in 22% of patients, but we noted no survival difference (5.2 months HER2+ vs. 9.8 months HER2neg; P = 0.95)., Conclusions: The median survival from esophageal-to-brain metastasis was 8.4 months. Patients with a single lesion, KPS score >70, and treatment with surgical resection was correlated with improved survival. Further, HER2+ patients had distinct patient and BrM characteristics., (Copyright © 2024. Published by Elsevier Inc.)

Background: Brain metastases from endometrial cancer are rare and poorly described. We aimed to estimate the proportion of brain metastases at our institution that arose from endometrial cancer, and to detail clinicopathologic features and survival outcomes., Methods: We retrospectively identified and reviewed the charts of 30 patients with brain metastases from endometrial cancer seen at Stanford Hospital from 2008 to 2018., Results: Among all patients with brain metastases, the proportion arising from endometrial cancer was 0.84%. The median age at diagnosis was 62 years (range, 39-79 years), and the median overall survival from brain metastasis diagnosis was 6.8 months (range, 1.0-58.2 months). Most patients harbored endometrioid histology (53.3%), and some had concurrent metastases to lung (50.0%), bone (36.7%), and liver (20.0%). The median time from endometrial cancer diagnosis to brain metastasis development was 20.8 months (range, 1.4 months to 11.2 years), and the median number of brain metastases was 2 (range, 1-20). Patients with non-endometrioid histologies had more brain metastases than those with endometrioid histology (6.21 vs. 2.44, P = 0.029). There was no difference in overall survival by histology., Conclusions: We describe the largest cohort to date of patients with brain metastases originating from endometrial cancer. These patients represent a small fraction of all patients with brain metastases and have poor prognoses. These data enable providers caring for patients with brain metastases from endometrial cancer to appropriately counsel their patients., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Objective: Immunotherapy for patients with melanoma with brain metastasis has significantly improved outcomes; however, it has also been characterized by potentially dangerous immune-related adverse events (IRAEs). Several reports have suggested that these reactions can precede improved treatment responses. For intracranial disease control, we sought to identify if such an association exists., Methods: We conducted a retrospective chart review of patients with melanoma who underwent immunotherapy treatment after diagnosis of brain metastasis. The study cohort was then stratified into 2 groups based on their history of developing an IRAE that prompted discontinuation of that regimen. The primary outcome variable included intracranial progression-free survival (PFS). Kaplan-Meier and Cox proportional hazard analyses were used to evaluate survival and predictors of outcomes., Results: Fifty-two patients met the inclusion criteria, 17 of whom experienced severe IRAEs that led to discontinuation of immunotherapy. Median intracranial PFS was 19.9 versus 10.5 months (P = 0.053) in patients who did and did not experience severe IRAEs prompting discontinuation, respectively. No additional outcome benefits were identified for systemic PFS or overall survival (mean, 33.1 months and 27.6 months, respectively). Multivariable analysis identified BRAF mutation status as a negative prognosticator of brain progression (P = 0.013; hazard ratio, 3.90). Initial treatment with BRAF inhibitor was also a negative predictor of all-cause mortality (P = 0.015; hazard ratio, 10.73)., Conclusions: Immune-related adverse events may signify an underlying immunogenic response that has intracranial disease control benefits. Despite their associated side effects, immunotherapies continue to show promising outcomes as a first-line agent for melanoma with brain metastasis., (Copyright © 2020 Elsevier Inc.

Background: Brain metastases (BMs) from hepatocellular carcinoma (HCC) are rare, with a paucity of reported cases. In the present retrospective cohort report, we assessed the proportion of BMs arising from HCC and characterized the related details, including patient demographics, clinical characteristics, treatment modalities, and survival outcomes., Methods: We retrospectively identified and reviewed the medical records of 14 patients with BMs from HCC seen at our institution from 2008 to 2018., Results: Among all patients with BMs, the proportion originating from primary liver cancer was 0.39%. In every case (n = 14), the liver cancer was HCC. The median age at the BM diagnosis was 64 years (range, 37-82 years). The median alpha-fetoprotein level at the diagnosis of BM was 540 ng/mL (range, 3-10,000 ng/mL). The median interval from the HCC diagnosis to the development of BMs was 31.1 months (range, 3.17-107 months). Of the 14 patients, 8 (57%) had had metastases to the brain parenchyma and 6 had had skull or dural metastases. For patients with brain parenchymal metastases, the median number of metastases was 1 (range, 1-5). Of the 14 patients, 13 have died, with a median overall survival after the BM diagnosis of 2.83 months (range, 0.430-24.0 months). At the latest follow-up examination, the survival for the 14th patient was 142 months after the BM diagnosis. Resection of BMs with radiosurgery was associated with increased survival compared with radiosurgery alone (10.9 months vs. 2.8 months; P = 0.04)., Conclusions: HCC BMs are rare and constitute a small fraction of the total incidence of BMs. The prognostic data we have provided can aid medical providers in caring for patients with HCC BMs., (Copyright © 2020 Elsevier Inc.

Background: Brain metastases from prostate cancer are rare and poorly described. We sought to assess the proportion of brain metastases arising from prostate cancer and to detail clinical characteristics, treatment modalities, and survival outcomes., Methods: We retrospectively identified and reviewed the charts of 31 patients with intraparenchymal brain metastases from prostate adenocarcinoma seen at our institution from 2008 to 2018., Results: Among all patients with brain metastases, the proportion originating from prostate adenocarcinoma was 0.86%. The median age at the time of brain metastasis diagnosis was 69 (range, 57-90). The median original Gleason score was 8 (range, 6-10), and the median prostate-specific antigen at the time of brain metastasis was 60 ng/mL (range, 0.34-4600). The median months from initial cancer diagnosis to brain metastasis was 81 (range, 3-195). The median number of brain metastases was 2 (range, 1-5). Patients had concurrent metastases to bone (100%), lung (48%), and liver (35%). Median overall survival was 3 months (range, 0.4-25.0). Treatment of the brain metastases was correlated with an increase in median survival from 1.2 months to 4.6 months with radiosurgery (hazard ratio = 0.11, P = 0.001) and surgical resection plus radiotherapy to 13 months (hazard ratio = 0.05, P < 0.001). All patients died of advanced, systemic disease and not of their intracranial disease., Conclusions: Brain metastasis from prostate cancer constitutes a small fraction of total brain metastases, but is associated with poor prognosis and is seen in the setting of advanced, castrate resistant disease. These data enable treating physicians to appropriately counsel their patients with prostate adenocarcinoma brain metastasis., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Objectives: To assess the effectiveness of a clinical decision support tool consisting of an electronic medical record best practice alert (BPA) on the frequency of lumbar imaging in patients with acute low back pain in the ambulatory care setting, and to explore why providers order imaging outside of clinical guidelines., Methods: On March 23, 2016, we implemented a BPA pop-up alert that informed the ordering physician of the Choosing Wisely recommendation to not order imaging within the first 6 weeks of low back pain in the absence of red flags. We calculated imaging rates 1 year before and after implementation of the BPA. To override the BPA, providers could ignore the alert or explain their rationale for ordering imaging using either preset options or a free-text submission. We tracked preset options and manually reviewed 125 free-text submissions., Results: Significant decreases in both total imaging rate (9.6% decrease; P = 0.02) and magnetic resonance imaging rate (14.9% decrease; P < 0.01) were observed after implementation of the BPA. No change was found in the rates of X-ray or computed tomography scan orders. Almost two-thirds (64%) of the providers used preset options in overriding the BPA, and 36% of the providers entered a free-text submission. Among those providers using a free-text submission, 56% entered a non-guideline-supported rationale., Conclusions: The present study demonstrates the effectiveness of a simple, low-cost clinical decision support tool in reducing imaging rates for patients with acute low back pain. We also identify reasons why providers order imaging outside of clinical guidelines., (Copyright © 2019 Elsevier Inc. All rights reserved.)
