e21743 Background: Lung cancer is the most common cause of cancer-related mortality and most deaths are associated with metastatic disease, with brain being a common site. Historically, whole brain radiation therapy was the treatment of choice and resulted in median survivals in the range of 6 months. There is no consensus in management of patients who have brain metastasis with systemic disease.We aim to evaluate patients with brain metastasis from lung cancer for cause of death, to investigate whether patients died from central nervous system (CNS) progression or systemic disease or other/undetermined causes. Our hypothesis is that most deaths in contemporary patients with brain metastasis in lung cancer are due to systemic disease, and less commonly due to CNS progression. Methods: In this retrospective observational study, we did a chart review of all adult patients with non-small cell lung cancer and brain metastasis or leptomeningeal disease, who received treatment at Maimonides Cancer Center between 2010 and 2017. Patients with unavailable or incomplete medical records were excluded. Baseline characteristics, pathological factors of the tumor and cause of death was collected from the chart. The cause of death was categorized into systemic and brain causes, and difference in characteristics of patients and tumor were studied. Results: A total of 132 patients were included and their charts were reviewed. Out of 132, 96 could have a clear cause of death categorized into systemic or brain causes, the rest were either mixed or uncategorized. We found that 33% patients died of brain metastasis, and related causes, whereas 67% died of systemic disease progression. There were no different in the two groups in terms of gender, smoking status, histology, size of lung lesion, or number and size of brain lesion. The patients who died of brain metastasis had a significantly higher age, and worse Eastern Cooperative Oncology Group status. Interestingly, the patients who died of systemic causes more commonly had adrenal metastasis (12 vs 0) which was statistically significant, and liver (14 vs 3) metastasis which was not statistically significant. Conclusions: Two-thirds of patients with brain metastases died of systemic disease rather than CNS progression. This may reflect improvements in systemic and local therapies to forestall cancer progression in the CNS. This finding suggests that delaying systemic therapy for CNS treatment may negatively impact overall cancer control. More research needs to be done to answer this question with certainty, including prospective clinical trials.

Purpose We performed a multi-institutional study to identify prognostic factors and determine outcomes for patients with ALK-rearranged non–small-cell lung cancer (NSCLC) and brain metastasis. Patients and Methods A total of 90 patients with brain metastases from ALK-rearranged NSCLC were identified from six institutions; 84 of 90 patients received radiotherapy to the brain (stereotactic radiosurgery [SRS] or whole-brain radiotherapy [WBRT]), and 86 of 90 received tyrosine kinase inhibitor (TKI) therapy. Estimates for overall (OS) and intracranial progression-free survival were determined and clinical prognostic factors were identified by Cox proportional hazards modeling. Results Median OS after development of brain metastases was 49.5 months (95% CI, 29.0 months to not reached), and median intracranial progression-free survival was 11.9 months (95% CI, 10.1 to 18.2 months). Forty-five percent of patients with follow-up had progressive brain metastases at death, and repeated interventions for brain metastases were common. Absence of extracranial metastases, Karnofsky performance score ≥ 90, and no history of TKIs before development of brain metastases were associated with improved survival (P = .003, < .001, and < .001, respectively), whereas a single brain metastasis or initial treatment with SRS versus WBRT were not (P = .633 and .666, respectively). Prognostic factors significant by multivariable analysis were used to describe four patient groups with 2-year OS estimates of 33%, 59%, 76%, and 100%, respectively (P < .001). Conclusion Patients with brain metastases from ALK-rearranged NSCLC treated with radiotherapy (SRS and/or WBRT) and TKIs have prolonged survival, suggesting that interventions to control intracranial disease are critical. The refinement of prognosis for this molecular subtype of NSCLC identifies a population of patients likely to benefit from first-line SRS, close CNS observation, and treatment of emergent CNS disease.
