Abstract
BACKGROUND Brain metastasis increases morbidity and mortality in cancer patients. This study was undertaken to compare tumor response and treatment-related toxicities in patients treated with orally administered thalidomide concomitantly with whole brain radiotherapy to whole brain radiotherapy alone in brain metastases. METHODS This randomized control trial was conducted in radiation oncology department, RIMS among 42 patients of brain metastases distributed in two study arms during the period August 2018 to July 2020. Twenty patients in Arm-A received whole brain radiotherapy to a dose of 3,750 cGy in 15 fractions with concomitant oral thalidomide 200 mg daily in first week and 400 mg/day from second week of radiation onward till the end of radiotherapy, whereas 20 patients of Arm-B received whole brain radiation of 3,750 cGy in 15 fractions alone. RESULTS Patient characteristics were comparable. Median central nervous system progression free survival was 2 months for Arm-A and 3 months for Arm-B, whereas median overall survival study was 4 months for Arm-A and 3 months for Arm-B. Overall response rate in Arm-A was 56% and in Arm-B was 44%. Treatment-related toxicities were more in arm-A but were manageable. CONCLUSION Addition of thalidomide to whole brain radiotherapy makes no significant difference. Though not statistically significant, but still, Arm-A had shown some percentage benefits. Further studies with larger sample sizes should be done.

Abstract
Background Brain metastases are a common complication in a wide range of cancers but are ubiquitous among patients with lung cancer. Limited data are available on the survival of patients with lung cancer and brain metastases in Indonesia. In this study, we aimed to identify the factors that might contribute to and predict survival in patients with non-small cell lung cancer (NSCLC) that resulted in brain metastases. Methods This retrospective study on patients with NSCLC and brain metastases was conducted using data available from the medical records of the Dharmais National Cancer Hospital, Jakarta, Indonesia. The study outcome was survival time, which was associated with sex, age, smoking status, body mass index, number of brain metastases, tumor location, systemic therapy, and other therapies. Descriptive statistics, median survival, Kaplan-Meier graphs, and Cox regression were analyzed using SPSS version 27. Results We included 111 patients with NSCLC and brain metastases in this study. The median patient age was 58 years. Long survivorship was observed among women (median: 95.4 weeks; P < .0003), patients with epidermal growth factor receptor (EGFR) mutations (median: 41.8 weeks; P < .0492), those who received chemotherapy (median: 58 weeks; P < .000), and those who received a combination of surgery and whole brain radiotherapy (WBRT; median: 64.7 weeks; P = .0174). Multivariate analysis showed consistent results for the following factors: sex, EGFR mutations, systemic therapy, and surgery plus WBRT. Conclusions Female sex and EGFR mutations in patients with NSCLC and brain metastases are associated with a high survival rate. Patients who have NSCLC with brain metastases will benefit from treatment with EGFR tyrosine kinase inhibitors, chemotherapy, and surgery plus WBRT.

Abstract
More clinical evidence is needed regarding the relative priority of treatments for brain metastases (BMs) from EGFR/ALK-negative/unselected non-small cell lung cancer (NSCLC). PubMed, EMBASE, Web of Science, Cochrane Library, and ClinicalTrials.gov databases were searched. Overall survival (OS), central nervous system progression-free survival (CNS-PFS), and objective response rate (ORR) were selected for Bayesian network meta-analyses. We included 25 eligible randomized control trials (RCTs) involving 3,054 patients, investigating nine kinds of treatments for newly diagnosed BMs and seven kinds of treatments for previously treated BMs. For newly diagnosed BMs, adding chemotherapy, EGFR-TKIs, and other innovative systemic agents (temozolomide, nitroglycerin, endostar, enzastaurin, and veliparib) to radiotherapy did not significantly prolong OS than radiotherapy alone; whereas radiotherapy + nitroglycerin showed significantly better CNS-PFS and ORR. Surgery could significantly prolong OS (hazard ratios [HR]: 0.52, 95% credible intervals: 0.41-0.67) and CNS-PFS (HR: 0.32, 95% confidence interval: 0.18-0.59) compared with radiotherapy alone. For previously treated BMs, pembrolizumab + chemotherapy, nivolumab + ipilimumab, and cemiplimab significantly prolonged OS than chemotherapy alone. Pembrolizumab + chemotherapy also showed better CNS-PFS and ORR than chemotherapy. In summary, immune checkpoint inhibitor (ICI)-based therapies, especially ICI-combined therapies, showed promising efficacies for previously treated BMs from EGFR/ALK-negative/unselected NSCLC. The value of surgery should also be emphasized. The result should be further confirmed by RCTs.

Abstract
IntroductionRadiotherapy (RT) is currently the main treatment for brain metastases (BMs) from non-small cell lung cancer (NSCLC). Due to the short survival time and obvious adverse reactions of RT, we urgently need more appropriate treatment. This network meta-analysis reviewed the efficacy and adverse effects of radiotherapy-based combination therapy for patients without targeted epidermal growth factor receptor (EGFR) mutations/anaplastic lymphoma kinase (ALK) gene rearrangement NSCLC BMs, to screen out the therapy with the best efficacy.MethodsPubMed, Embase, Web of Science, and Cochrane Library were searched from the earliest publication date available to 1 April 2022. STATA15.0 was used to conduct heterogeneity analysis, sensitivity analysis, forest plot analysis, and publication bias analysis.ResultsA total of 28 studies, involving 3707 patients were included in the Bayesian network meta-analysis. In the limited paired meta-analysis for head-to-head comparative trials, compared with RT-based combination therapy, RT combined with Immune checkpoint inhibitors (ICIs) showed significant overall survival (OS) benefit (HR 0.65, 95%CI 0.47–0.9, p<0.01), RT combined with ICIs showed a non-significant difference for intracranial progression-free survival (iPFS) (HR 0.76, 95%CI 0.27–2.27, p<0.01) and progression-free survival (PFS) (HR 0.9, 95%CI 0.36–2.37, p<0.01). In addition, according to the ranking results, compared with RT combined with chemotherapy(CT) or with targeted therapy(TT), RT combined with ICIs might be the best treatment mode for OS(ICIs+RT vs CT+RT vs TT+RT; 91.9% vs. 27.8% vs. 29.3%, iPFS (ICIs+RT vs CT+RT vs TT+RT, 46.9% vs 25.2% vs 25.6%) and PFS (ICIs+RT vs CT+RT vs TT+RT, 36.2% vs 31% vs 36.5%).ConclusionsRT combined with ICIs might be the best treatment mode to prolong the OS for BMs from NSCLC with non-EGFR mutation/ALK gene rearrangement.Review Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022350065, identifier (CRD42022350065)

Abstract
Brain metastases are a common occurrence in both non-small cell and small cell lung cancer with the potential to affect quality of life and prognosis. Due to concerns about the accessibility of the central nervous system by systemic chemotherapy agents, the management of brain metastases has historically relied on local therapies including surgery and radiation. However, novel targeted and immune therapies that improve overall outcomes in lung cancer have demonstrated effective intracranial activity. As a result, the management of brain metastases in lung cancer has evolved, with both local and systemic therapies now playing an important role. Factors such as tumor histology (non-small versus small cell), oncogenic driver mutations, and symptom burden from intracranial disease impact treatment decisions. Here, we review the current management of brain metastases in lung cancer, highlighting the roles of stereotactic radiosurgery and novel systemic therapies as well as the ongoing questions that remain under investigation.

Abstract
INTRODUCTION As many as 30% of patients with non-small cell lung cancer (NSCLC) will develop brain metastases (BMs) over the course of their illness. Here, we quantitatively compare the efficacy of the various emerging regimens for NSCLC BMs without a definitive targetable epidermal growth factor receptor mutation/ALK rearrangement. METHODS We searched MEDLINE, EMBASE, Web of Science, ClinicalTrials.gov, CENTRAL, and references of key studies for randomized controlled trials (RCTs) published from inception until June 2020. Comparative RCTs that included ≥10 patients were included. We used a frequentist fixed or random-effects model for network meta-analysis. The outcomes of interest included intracranial progression-free survival (iPFS), overall survival (OS), and overall progression-free survival. RESULTS In total, 18 studies representing 17 trials (n = 2726 patients) were identified. Immune checkpoint inhibitor regimens showed significant improvement in OS compared with chemotherapy alone, including pembrolizumab and chemotherapy (6 studies, hazard ratio [HR] 0.36, 95% confidence interval [CI] 0.21-0.62), atezolizumab alone (HR 0.54, 95% CI 0.33-0.89), and nivolumab and ipilimumab (HR 0.64, 95% CI 0.42-0.97). An improvement in overall PFS was seen with use of pembrolizumab and chemotherapy compared with chemotherapy alone (3 studies, HR 0.42, 95% CI 0.26-0.68). Studies evaluating checkpoint inhibitors did not report iPFS data, and we did not find improvement in iPFS or OS with the addition of any chemotherapy regimen to whole-brain radiation therapy. CONCLUSIONS In this network meta-analysis, we demonstrate the promising survival benefit with use of checkpoint inhibitor-based regimens in NSCLC BMs without a targetable epidermal growth factor receptor mutation/ALK rearrangement. Moving forward, large-scale BM-focused RCTs are necessary to establish the iPFS benefit of immune checkpoint inhibitor-based immunotherapy in this patient population.

Abstract
INTRODUCTION At present, there is no uniform consensus on the treatment of brain metastases from esophageal cancer. The studies on the treatment of brain metastases from esophageal cancer by radiotherapy combined with temozolomide (TMZ) are even rarer. PATIENT CONCERNS A 69-year-old woman was admitted to our hospital for brain metastases from esophageal cancer after thoracic irradiation. DIAGNOSES Magnetic resonance imaging of the head showed a round, heterogeneous metastatic tumor in the left parietal lobe. Brain magnetic resonance imaging showed edema around brain metastasesInterventions: After radiotherapy plus TMZ in this patient's head, the brain metastatic tumor was significantly decreased. OUTCOMES At the end of radiotherapy, and 1 and 2 months after the end of radiotherapy, the metastatic tumor continued to shrink, and no obvious side effects were observed. LESSONS This study suggests that radiotherapy plus TMZ might be a feasible option for brain metastases from esophageal cancer.

Abstract
Short-term efficacy, adverse effects and the impact on quality of life (QoL) of a concomitant treatment with intensity-modulated radiation therapy (IMRT) and temozolomide (TMZ) in patients with brain metastases (BMs) from lung adenocarcinoma were evaluated. This study sought to confirm the benefit of adding TMZ to IMRT in patients with BMs from lung adenocarcinoma. Nine patients were enrolled and received a dose of 30 Gy in 10 daily fractions to clinical tumor volume (CTV) according to IMRT, then additional dose of 9 Gy in 3 fractions of IMRT was delivered to gross tumor volume (GTV) only with concomitant TMZ (75 mg/m2/day) orally during RT for 3 weeks. One patient achieved complete response (CR) (11.1%), 6 patients obtained partial response (PR) (66.7%), and there were no patients in progression. Therefore, objective response (OR) reached 77.8%. The main adverse effects included neutropenia, anemia, vomiting, fatigue and dizziness. Grade ≥3 of hematologic toxicities did not occur. However, the other 9 patients who received only intensity-modulated radiation had much worse results. The CR was 0, PR rate was 44.4%, OR rate was 44.4%. The results indicated that the benefit of adding TMZ to IMRT was confirmed in patients with BMs from lung adenocarcinoma. The treatment was active, a significant OR was observed, and achieved an improvement in QoL demonstrated by QoL grade (p<0.05).

Abstract
BACKGROUND This is an update to the review published in the Cochrane Library (2012, Issue 4).It is estimated that 20% to 40% of people with cancer will develop brain metastases during the course of their illness. The burden of brain metastases impacts quality and length of survival. OBJECTIVES To assess the effectiveness and adverse effects of whole brain radiotherapy (WBRT) given alone or in combination with other therapies to adults with newly diagnosed multiple brain metastases. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and Embase to May 2017 and the National Cancer Institute Physicians Data Query for ongoing trials. SELECTION CRITERIA We included phase III randomised controlled trials (RCTs) comparing WBRT versus other treatments for adults with newly diagnosed multiple brain metastases. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and abstracted information in accordance with Cochrane methods. MAIN RESULTS We added 10 RCTs to this updated review. The review now includes 54 published trials (45 fully published reports, four abstracts, and five subsets of data from previously published RCTs) involving 11,898 participants.Lower biological WBRT doses versus controlThe hazard ratio (HR) for overall survival (OS) with lower biological WBRT doses as compared with control (3000 cGy in 10 daily fractions) was 1.21 (95% confidence interval (CI) 1.04 to 1.40; P = 0.01; moderate-certainty evidence) in favour of control. The HR for neurological function improvement (NFI) was 1.74 (95% CI 1.06 to 2.84; P = 0.03; moderate-certainty evidence) in favour of control fractionation.Higher biological WBRT doses versus controlThe HR for OS with higher biological WBRT doses as compared with control (3000 cGy in 10 daily fractions) was 0.97 (95% CI 0.83 to 1.12; P = 0.65; moderate-certainty evidence). The HR for NFI was 1.14 (95% CI 0.92 to 1.42; P = 0.23; moderate-certainty evidence).WBRT and radiosensitisersThe addition of radiosensitisers to WBRT did not confer additional benefit for OS (HR 1.05, 95% CI 0.99 to 1.12; P = 0.12; moderate-certainty evidence) or for brain tumour response rates (odds ratio (OR) 0.84, 95% CI 0.63 to 1.11; P = 0.22; high-certainty evidence).Radiosurgery and WBRT versus WBRT aloneThe HR for OS with use of WBRT and radiosurgery boost as compared with WBRT alone for selected participants was 0.61 (95% CI 0.27 to 1.39; P = 0.24; moderate-certainty evidence). For overall brain control at one year, the HR was 0.39 (95% CI 0.25 to 0.60; P < 0.0001; high-certainty evidence) favouring the WBRT and radiosurgery boost group.Radiosurgery alone versus radiosurgery and WBRTThe HR for local brain control was 2.73 (95% CI 1.87 to 3.99; P < 0.00001; high-certainty evidence)favouring the addition of WBRT to radiosurgery. The HR for distant brain control was 2.34 (95% CI 1.73 to 3.18; P < 0.00001; high-certainty evidence) favouring WBRT and radiosurgery. The HR for OS was 1.00 (95% CI 0.80 to 1.25; P = 0.99; moderate-certainty evidence). Two trials reported worse neurocognitive outcomes and one trial reported worse quality of life outcomes when WBRT was added to radiosurgery.We could not pool data from trials related to chemotherapy, optimal supportive care (OSC), molecular targeted agents, neurocognitive protective agents, and hippocampal sparing WBRT. However, one trial reported no differences in quality-adjusted life-years for selected participants with brain metastases from non-small-cell lung cancer randomised to OSC and WBRT versus OSC alone. AUTHORS' CONCLUSIONS None of the trials with altered higher biological WBRT dose-fractionation schemes reported benefit for OS, NFI, or symptom control compared with standard care. However, OS and NFI were worse for lower biological WBRT dose-fractionation schemes than for standard dose schedules.The addition of WBRT to radiosurgery improved local and distant brain control in selected people with brain metastases, but data show worse neurocognitive outcomes and no differences in OS.Selected people with multiple brain metastases from non-small-cell lung cancer may show no difference in OS when OSC is given and WBRT is omitted.Use of radiosensitisers, chemotherapy, or molecular targeted agents in conjunction with WBRT remains experimental.Further trials are needed to evaluate the use of neurocognitive protective agents and hippocampal sparing with WBRT. As well, future trials should examine homogeneous participants with brain metastases with focus on prognostic features and molecular markers.

Abstract
We hypothesized that sorafenib (BAY 43-9006), an oral multi-kinase inhibitor, used in combination with SRS will improve overall intracranial control. This Phase I study assesses the safety, tolerability, and maximal tolerated dose of sorafenib administered with SRS to treat 1-4 brain metastases. This was an open label phase I dose escalation study with an expansion cohort. Eligible adults had 1-4 brain metastases from solid malignancies. Sorafenib was begun 5-7 days prior to SRS and continued for 14 days thereafter. Dose escalation of sorafenib was conducted via a "3 + 3" dose escalation design. Dose limiting toxicities (DLT) were determined 1 month after SRS and defined as ≥grade 3 neurologic toxicities. Twenty-three patients were enrolled. There were no DLTs at dose level 1 (400 mg per day) or dose level 2 (400 mg twice per day). An expansion cohort of 17 patients was treated at dose level 2. There were six grade 3 toxicities: hypertension (n = 2), rash (n = 1), lymphopenia (n = 1), hypokalemia (n = 1), fatigue (n = 1) and hand-foot syndrome (n = 1). All of these were attributable to sorafenib and not to the combination with SRS. The median time to CNS progression was 10 months, 1 year CNS progression-free survival was 46%, the median overall survival was 11.6 months and the 1 year overall survival was 46%. The use of sorafenib concurrent with SRS for the treatment of 1-4 brain metastases is safe and well tolerated at 400 mg twice a day. Our recommended phase II dose of concurrent sorafenib with SRS would be 400 mg twice daily.

Abstract
The incidence of brain metastases from nonsquamous non-small-lung cancer is increasing as a result of superior imaging techniques for early detection of distant metastases. Although whole-brain radiation therapy and stereotactic radiosurgery along with systemic chemotherapy have shown to be effective in alleviating symptoms and improving outcomes, the approach to patients with asymptomatic brain metastases remains elusive. We explored the literature for a possible role of frontline systemic chemotherapy in asymptomatic brain metastases from nonsquamous non-small-lung cancer and found promising evidence that upfront systemic therapy with pemetrexed-platinum regimens might be a reasonable option for these patients and would forestall the need for upfront brain radiation therapy. More large-scale phase II and phase III clinical trials are needed to further investigate the frontline use of pemetrexed-platinum regimens in this setting.

Abstract
The present study aimed to investigate the efficacy and safety of different therapeutic regimens for brain metastases (BMs) from lung cancer (LC). A total of 13 controlled trials (1,783 cases) involving chemotherapy, tyrosine kinase inhibitors or endostatin plus radiotherapy (combination group) vs. radiotherapy alone group were identified from PubMed. Compared with the radiotherapy alone group, the combination group resulted in a significant benefit for objective response rate (ORR) [risk ratio (RR), 1.38; 95% confidence interval (CI), 1.19–1.60; P<0.0001], notably prolonged the time to central nervous system progression [CNS-TTP; hazard ratio (HR), 0.71; 95% CI, 0.57–0.90; P=0.004] and progression-free survival (PFS; HR, 0.60; 95% CI, 0.44–0.83; P=0.002); however, failed in prolonging the overall survival (OS; HR, 0.80; 95% CI, 0.61–1.05; P=0.11) with a higher overall severe adverse events (AEs, Grade ≥3; RR, 2.57; 95% CI, 1.24–5.35; P=0.01). Notably, subgroup analysis demonstrated that targeted therapy plus radiotherapy possessed a superior OS compared with radiotherapy alone (HR, 0.58; 95% CI, 0.37–0.90; P=0.01) with mild non-hematological toxicity and without severe hematotoxicity. The present study demonstrated that targeted agents plus radiotherapy possessed desirable effects with mild adverse events. Secondary to best, chemoradiotherapy is an alternative option for patients without suitable molecular targets.

Abstract
The incidence of brain metastases of solid tumors is increasing. Local treatment of brain metastases is generally straightforward: cranial radiotherapy (e.g., whole-brain radiotherapy or stereotactic radiosurgery) or resection when feasible. However, treatment becomes more complex when brain metastases occur while other metastases, outside of the central nervous system, are being controlled with systemic therapy (chemotherapeutics, molecular targeted agents, or monoclonal antibodies). It is known that some anticancer agents can increase the risk for neurotoxicity when used concurrently with radiotherapy. Increased neurotoxicity decreases quality of life, which is undesirable in this predominantly palliative patient group. Therefore, it is of utmost importance to identify the compounds that should be temporarily discontinued when cranial radiotherapy is needed.This review summarizes the (neuro)toxicity data for combining systemic therapy (chemotherapeutics, molecular targeted agents, or monoclonal antibodies) with concurrent radiotherapy of brain metastases. Because only a limited amount of high-level data has been published, a risk assessment of each agent was done, taking into account the characteristics of each compound (e.g., lipophilicity) and the microenvironment of brain metastasis. The available trials suggest that only gemcitabine, erlotinib, and vemurafenib induce significant neurotoxicity when used concurrently with cranial radiotherapy. We conclude that for most systemic therapies, the currently available literature does not show an increase in neurotoxicity when these therapies are used concurrently with cranial radiotherapy. However, further studies are needed to confirm safety because there is no high-level evidence to permit definitive conclusions. The Oncologist 2017;22:222-235Implications for Practice: The treatment of symptomatic brain metastases diagnosed while patients are receiving systemic therapy continues to pose a dilemma to clinicians. Will concurrent treatment with cranial radiotherapy and systemic therapy (chemotherapeutics, molecular targeted agents, and monoclonal antibodies), used to control intra- and extracranial tumor load, increase the risk for neurotoxicity? This review addresses this clinically relevant question and evaluates the toxicity of combining systemic therapies with cranial radiotherapy, based on currently available literature, in order to determine the need to and interval to interrupt systemic treatment.

Abstract
Chemotherapy is the mainstay of treatment of advanced non-small cell lung cancer (NSCLC) without molecular drivers. Despite a low penetration of central nervous system (CNS), chemotherapy drugs demonstrated encouraging activity against CNS metastases from NSCLC. Based on the available data, chemotherapy should be considered as an important part of the multidisciplinary treatment of CNS metastases. Particularly, platinum-based regimens represent the most active combinations and pemetrexed is associated with a meaningful clinical benefit for patients with non-squamous histology. How to integrate chemotherapy and radiotherapy for newly diagnosed brain metastases (BMs) is still debated. Although flawed by some limitations, the available evidence suggests a role for upfront chemotherapy for the treatment of NSCLC patients with synchronous, asymptomatic BMs, thus allowing a delay of radiotherapy. Despite the introduction of modern and more effective chemotherapy, however, the prognosis of NSCLC patients with CNS metastases remains poor, especially for those with progressive BMs or leptomeningeal carcinomatosis (LC).

Abstract
Lung cancer is one of the major causes of cancer related mortality worldwide. Brain metastases (BM) complicate clinical evolution of non-small cell lung cancer (NSCLC) in approximately 25-40% of cases, adversely influencing quality of life (QoL) and overall survival (OS). Systemic therapy remains the standard strategy for metastatic disease. Nevertheless, the blood-brain barrier (BBB) makes central nervous system (CNS) a sanctuary site. To date, the combination of chemotherapy with whole brain radiation therapy (WBRT), surgery and/or stereotactic radiosurgery (SRS) represents the most used treatment for patients (pts) with intracranial involvement. However, due to their clinical conditions, many pts are not able to undergo local treatments. Targeted therapies directed against epidermal growth factor receptor (EGFR), such as gefitinib, erlotinib and afatinib, achieved important improvements in EGFR mutated NSCLC with favorable toxicity profile. Although their role is not well defined, the reported objective response rate (ORR) and the good tolerance make EGFR-tyrosine kinase inhibitors (TKIs) an interesting valid alternative for NSCLC pts with BM, especially for those harboring EGFR mutations. Furthermore, new-generation TKIs, such as osimertinib and rociletinib, have already shown important activity on intracranial disease and several trials are still ongoing to evaluate their efficacy. In this review we want to highlight literature data about the use and the effectiveness of EGFR-TKIs in pts with BM from NSCLC.

Abstract
The clinical management/understanding of brain metastases (BM) has changed substantially in the last 5 years, with key advances and clinical trials highlighted in this review. Several of these changes stem from improvements in systemic therapy, which have led to better systemic control and longer overall patient survival, associated with increased time at risk for developing BM. Development of systemic therapies capable of preventing BM and controlling both intracranial and extracranial disease once BM are diagnosed is paramount. The increase in use of stereotactic radiosurgery alone for many patients with multiple BM is an outgrowth of the desire to employ treatments focused on local control while minimizing cognitive effects associated with whole brain radiotherapy. Complications from BM and their treatment must be considered in comprehensive patient management, especially with greater awareness that the majority of patients do not die from their BM. Being aware of significant heterogeneity in prognosis and therapeutic options for patients with BM is crucial for appropriate management, with greater attention to developing individual patient treatment plans based on predicted outcomes; in this context, recent prognostic models of survival have been extensively revised to incorporate molecular markers unique to different primary cancers.

Abstract
Objective The study was designed to evaluate the efficacy and safety of tyrosine kinase inhibitors (TKIs) plus radiotherapy in patients with brain metastases (BM) of non-small cell lung cancer. Methods Medline PubMed, Google Scholar, Web of Science, Oxford Journals Collection, clinical trials and current controlled trials were searched to identify relevant publications. After screening literature and undertaking quality assessment and data extraction, the meta-analysis was performed using RevMan5.3 software. Results Eight controlled trials (980 participants) were included in the study. Compared with radiotherapy without TKIs (non-TKI-group), TKIs plus radiotherapy (TKI-group) had a significant benefit on objective response rate (ORR) (RR = 1.56, 95%CI [1.25,2.03]; P =0.0008), significantly prolonged the time to central nerves system progression (CNS-TTP) (HR =0.58, 95% CI [0.35, 0.96]; P =0.03) and median overall survival (MOS) (HR =0.68, 95% CI [0.47, 0.98]; P =0.04) of NSCLC patients with BM. There was no significant difference in overall severe adverse events (Grade≥3) (RR = 1.49, 95% CI [0.88,2.54]; P = 0.14) between two groups. Conclusion This meta-analysis showed TKI-group produced superior response rate when compared with non-TKI-group. TKIs plus radiotherapy significantly prolong the CNS-TTP and MOS of patients without enhancing overall severe adverse events.

Abstract
Non-small-cell lung cancer (NSCLC) brain metastases are common. Even though there are various subsets of NSCLC with molecular alterations, there is a common theme of brain metastases. Current treatment modalities are suboptimal. Systemic therapies for the treatment of NSCLC brain metastases have been explored and recent advances may pave the way for their successful employment in this patient population. While no specific agents have been associated with a marked benefit, stability of disease as well as radiographic responses have been noted in some patients. Biological activity of systemic therapies in some patients with NSCLC brain metastases raises hope for future advances and supports further investigation for this patient population with limited treatment options.

Abstract
Brain metastasis (BM) is the common complication of non‐small cell lung cancer (NSCLC) with a poor prognosis and dismal survival rate. This update meta‐analysis aimed to derive a more precise estimation of radiotherapy plus epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in NSCLC patients with BM. PubMed, EMBASE, Web of Science, Google Scholar, and Cochrane Library were searched to identify any relevant publications. After screening the literature and undertaking quality assessment and data extraction, the meta‐analysis was performed using STATA Version 12.0. In total, 15 studies involving 1552 participants were included. The results indicated that radiotherapy plus EGFR TKIs was more effective at improving response rate and disease control rate (DCR) (risk ratio (RR) = 1.48, 95% confidence interval [CI]: 1.12–1.96, P = 0.005; RR = 1.29, 95% CI: 1.02–1.60, P = 0.035; respectively) than radiotherapy alone or plus chemotherapy. Moreover, radiotherapy plus EGFR TKIs significantly prolonged the time to central nervous system progression (CNS‐TTP) (HR = 0.56, 95% CI [0.33, 0.80]; P = 0.000) and median overall survival (OS) (HR = 0.58, 95% CI [0.42, 0.74]; P = 0.000) but significantly increased adverse events (any grade) (RR = 1.25, 95% CI [1.01, 1.57]; P = 0.009), especially rash and dry skin. These results suggested that radiotherapy plus EGFR TKIs produced superior response rate and DCR and markedly prolonged the CNS‐TTP and OS of NSCLC patients with BM. However, combined groups had the higher rate of incidence of overall adverse effects, especially rash and dry skin.

Abstract
Lung cancer remains the leading cause of cancer mortality in men and women in the U.S. and worldwide. About 90% of lung cancer cases are caused by smoking and the use of tobacco products. However, other factors such as radon gas, asbestos, air pollution exposures, and chronic infections can contribute to lung carcinogenesis. In addition, multiple inherited and acquired mechanisms of susceptibility to lung cancer have been proposed. Lung cancer is divided into two broad histologic classes, which grow and spread differently: small-cell lung carcinomas (SCLCs) and non-small cell lung carcinomas (NSCLCs). Treatment options for lung cancer include surgery, radiation therapy, chemotherapy, and targeted therapy. Therapeutic-modalities recommendations depend on several factors, including the type and stage of cancer. Despite the improvements in diagnosis and therapy made during the past 25 years, the prognosis for patients with lung cancer is still unsatisfactory. The responses to current standard therapies are poor except for the most localized cancers. However, a better understanding of the biology pertinent to these challenging malignancies, might lead to the development of more efficacious and perhaps more specific drugs. The purpose of this review is to summarize the recent developments in lung cancer biology and its therapeutic strategies, and discuss the latest treatment advances including therapies currently under clinical investigation.

Abstract
So far brain metastases represent a critical stage of a disease course and the frequency is increasing over the years. The treatment of brain metastases should be individualized for each patient: in case of single brain metastasis, surgery or radiosurgery should be considered as first options of treatment; in case of multiple lesions, whole-brain radiotherapy is the standard of care in association with systemic therapy or surgery/radiosurgery. Chemotherapy should be considered when surgery or radiation therapy are not possible. In the last decades, TKIs or monoclonal antibodies have shown increase in overall response rate and overall survival in Phase II-III trials. The aim of this paper is to make an overview of the current approaches in management of patients with brain metastases.

Abstract
Brain metastases (BMs) occur in 10% to 20% of adult patients with cancer, and with increased surveillance and improved systemic control, the incidence is likely to grow. Despite multimodal treatment, prognosis remains poor. Current evidence supports use of whole-brain radiation therapy when patients present with multiple BMs. However, its associated cognitive impairment is a major deterrent in patients likely to live longer than 6 months. In patients with oligometastases (one to three metastases) and even some with multiple lesions less than 3 to 4 cm, especially if the primary tumor is considered radiotherapy resistant, stereotactic radiosurgery is recommended; if the BMs are greater than 4 cm, surgical resection with or without postoperative whole-brain radiation therapy should be considered. There is increasing evidence that systemic therapy, including targeted therapy and immunotherapy, is effective against BM and may be an early choice, especially in patients with sensitive primary tumors. In patients with progressive systemic disease, limited treatment options, and poor performance status, best supportive care may be appropriate. Regardless of treatment goals, use of corticosteroids or antiepileptic medications is helpful in symptomatic patients. In this review, we provide a summary of current therapy, as well as developments in the treatment of BM from solid tumors.

Abstract
Systemic treatment of lung cancer patients with brain metastases is based on clinical (presence of symptomatic intracranial lesions), pathological and molecular characteristics of the disease. The efficacy of standard platinum-based chemotherapy is comparable inside and outside the brain, justifying its use as front-line therapy. The intracranial efficacy of targeted therapies (EGFR tyrosine kinase inhibitors, ALK inhibitors) is demonstrated, and is globally superior to the efficacy of standard chemotherapy, justifying their use as front-line therapy in case of EGFR activating mutation or ALK rearrangement (providing the change in the crizotinib label in France). The concomitant use of whole brain radiotherapy and a systemic treatment (chemotherapy or targeted therapy) is not recommended in the absence of a demonstrated better efficacy and/or acceptable safety profile. Several trials are ongoing to assess new whole brain radiotherapy modalities, new targeted therapies alone or in combination, especially exploring immunotherapy.

Abstract
OBJECTIVE The aim of the present meta-analysis is to evaluate the response rate, median survival time (MST) and toxicity in patients with brain metastases (BM) originating from non-small cell lung cancer (NSCLC) and who were treated using either whole brain radiotherapy (WBRT) plus concurrent chemotherapy or WBRT alone. METHODS PubMed, EMBASE, Web of Science, The Cochrane Library, clinical trials and current controlled trials were searched to identify any relevant publications. After screening the literature and undertaking quality assessment and data extraction, the meta-analysis was performed using Stata11.0 software. RESULTS In total, six randomized controlled trials (RCT) involving 910 participants were included in the meta-analysis. The results of the analysis indicate that WBRT plus concurrent chemotherapy was more effective at improving response rate (RR = 2.06, 95% CI [1.13, 3.77]; P = 0.019) than WBRT alone. However, WBRT plus concurrent chemotherapy did not improve median survival time (MST) (HR = 1.09, 95%CI [0.94, 1.26]; P = 0.233) or time of neurological progression (CNS-TTP) (HR = 0.93, 95%CI [0.75, 1.16]; P = 0.543), and increased adverse events (Grade≥3) (RR = 2.59, 95% CI [1.88, 3.58]; P = 0.000). There were no significant differences in Grade 3-5 neurological or hematological toxicity between two patient groups (RR = 1.08, 95%CI [0.23, 5.1]; P = 0.92). CONCLUSION The combination of chemotherapy plus WBRT in patients with BM originating from NSCLC may increase treatment response rates of brain metastases with limited toxicity. Although the therapy schedule did not prolong MST or CNS-TTP, further assessment is warranted.

Abstract
Primary and metastatic tumors of the central nervous system are a heterogeneous group of neoplasms with varied outcomes and management strategies. Recently, improved survival observed in 2 randomized clinical trials established combined chemotherapy and radiation as the new standard for treating patients with pure or mixed anaplastic oligodendroglioma harboring the 1p/19q codeletion. For metastatic disease, increasing evidence supports the efficacy of stereotactic radiosurgery in treating patients with multiple metastatic lesions but low overall tumor volume. These guidelines provide recommendations on the diagnosis and management of this group of diseases based on clinical evidence and panel consensus. This version includes expert advice on the management of low-grade infiltrative astrocytomas, oligodendrogliomas, anaplastic gliomas, glioblastomas, medulloblastomas, supratentorial primitive neuroectodermal tumors, and brain metastases. The full online version, available at NCCN. org, contains recommendations on additional subtypes.

Abstract
The folate antimetabolite pemetrexed was approved for the treatment of patients with metastatic nonsquamous non-small-cell lung carcinoma. Its activity on brain metastases makes pemetrexed attractive in combination with whole-brain radiation therapy (WBRT), but it could also potentially increase toxicity. We examined the medical records of 43 consecutive patients with brain metastases from non-small-cell lung carcinoma. Patients received pemetrexed-based chemotherapy at a dose of 500 mg/m. The median total number of pemetrexed-based chemotherapy cycles was 4 (range: 1-28). During the course of chemotherapy, patients received WBRT delivering 30 Gy in 10 fractions (n=34) or 20 Gy in five fractions (n=9). The median follow-up time was 30.5 weeks (range: 1-79 weeks). Intracranial progression was a cause of death in nine patients (20.9%). Clinical benefit of WBRT was reported in 30 patients (69.8%). The best radiological response was a complete response in eight patients (18.6%), a partial response in 16 patients (37.2%), stable disease in 11 patients (25.6%), and progression in four patients (9.3%). A stable intracranial disease until the last follow-up was observed in 26 patients (60.5%). The median estimated overall survival was 31 weeks (95% CI: 24-37 weeks). Most WBRT-related toxicities were low and 21 patients (48.9%) had no reported acute neurological toxicity. One patient developed unexplained encephalopathy 5 weeks after WBRT completion in the context of progressive diffuse brain metastases. The combination of pemetrexed with WBRT led to considerable clinical improvement and tumor responses in most patients. Overall neurological toxicity was rather low. A clinical trial is essential for better analysis of the potential synergistic effects of a drug with radiation and evaluation of neurological toxicity.

Abstract
Brain metastases are the most frequent neurological complication of cancer and the most common brain tumour type. Lung and breast cancers, and melanoma are responsible for up to three-quarters of metastatic brain lesions. Most patients exhibit either headache, seizures, focal deficits, cognitive or gait disorders, which severely impair the quality of life. Brain metastases are best demonstrated by MRI, which is sensitive but non-specific. The main differential diagnosis includes primary tumours, abscesses, vascular and inflammatory lesions. Overall prognosis is poor and depends on age, extent and activity of the systemic disease, number of brain metastases and performance status. In about half of the patients, especially those with widespread and uncontrolled systemic malignancy, death is heavily related to extra-neural lesions, and treatment of cerebral disease doesn't significantly improve survival. In such patients the aim is to improve or stabilize the neurological deficit and maintain quality of life. Corticosteroids and whole-brain radiotherapy usually fulfill this purpose. By contrast, patients with limited number of brain metastases, good performance status and controlled or limited systemic disease, may benefit from aggressive treatment as both quality of life and survival are primarily related to treatment of brain lesions. Several efficacious therapeutic options including surgery, radiotherapy and chemotherapy are available for these patients.

Abstract
BACKGROUND Chemotherapy and epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors are controversial in the treatment of patients with brain metastases from non-small-cell lung cancer (NSCLC). METHODS We retrospectively studied the effects of solely localized treatment or localized treatment in combination with chemotherapy and/or EGFR tyrosine kinase inhibitors on outcomes in 210 NSCLC patients with brain metastases. The effects of treatment modality, Karnofsky performance status, age, primary tumor histology, number of brain metastases, and other factors on survival time were analyzed, and the robustness of two prognostic indices, ie, recursive partitioning analysis and graded prognostic assessment, was evaluated. RESULTS The median survival time in patients with systemic medication and localized treatments was higher than in those with localized treatments alone (11 versus 3 months, P=0.000). Within the systemic medication group, median survival time was significantly longer for EGFR tyrosine kinase inhibitors than for other types of chemotherapy (12 versus 9 months, P=0.002). In the EGFR tyrosine kinase inhibitor group, median survival time for patients with EGFR gene mutation was 20 months versus 8 months for those with the wild-type EGFR gene. The median survival time with pemetrexed was significantly higher than with other chemotherapies (13 versus 7 months, P=0.006). In multivariate analysis, the prognosis was significantly correlated with treatment modality (P=0.000), Karnofsky performance status (P=0.000), number of brain metastases (P=0.001), and histologic tumor type (P=0.007). In the graded prognostic assessment model, survival curves for the subgroups showed clear separations. CONCLUSION NSCLC patients with brain metastasis benefited from pemetrexed and/or tyrosine kinase inhibitors along with localized treatments, and the graded prognostic assessment index is a robust model for prognostic evaluation.

Abstract
The aim of this paper is to explore the efficacy of whole brain radiotherapy (WBRT) versus WBRT concurrent with erlotinib in patients with multiple brain metastases of lung adenocarcinoma. WBRT was administered at 30Gy/10f in both arms. In the combination arm, 150 mg erlotinib was given each day, starting the first day of radiotherapy and continuing for 1 month following the end of radiotherapy. Thereafter, pemetrexed or docetaxel monotherapy or the best supportive therapy was given to both arms. The intracranial objective response rate and the local progression-free survival (LPFS) were primary endpoints. Toxicity, progression-free survival (PFS) and overall survival (OS) were secondary endpoints. Thirty-one patients in the WBRT group and 23 patients in the combination group were enrolled from November 2009 to December 2011. In the WBRT and the combination arms, respectively, the objective response rate was 54.84% and 95.65% (P = 0.001), the median local progression-free survival was 6.8 months and 10.6 months (P = 0.003), the median PFS was 5.2 months and 6.8 months (P = 0.009), and median OS was 8.9 months and 10.7 months (P = 0.020). In the combination group, there were no differences of LPFS, PFS, and OS between the epidermal growth factor receptor (EGFR) mutation patients and EGFR wild-type patients. No Grade 4 or higher side effects were observed in either group. A multivariate analysis indicated that erlotinib was the most important prognostic factor for a prolonged survival. Data showed that erlotinib in combination with WBRT had a tolerable toxicity profile and prolonged the LPFS, PFS, and OS of lung adenocarcinoma patients with multiple brain metastases compared with WBRT monotherapy.

Abstract
Background and purpose Chloroquine (CLQ), an antimalarial drug, has a lysosomotropic effect associated with increased radiationsensibility, which is mediated by the leakage of hydrolytic enzymes, increased apoptosis, autophagy and increased oxidative stress in vitro. In this phase II study, we evaluated the efficacy and safety of radiosensibilization using CLQ concomitant with 30 Gray (Gy) of whole-brain irradiation (WBI) to treat patients with brain metastases (BM) from solid tumors. Methods Seventy-three eligible patients were randomized. Thirty-nine patients received WBI (30 Gy in 10 fractions over 2 weeks) concomitant with 150 mg of CLQ for 4 weeks (the CLQ arm). Thirty-four patients received the same schedule of WBI concomitant with a placebo for 4 weeks (the control arm). All the patients were evaluated for quality of life (QoL) using the EORTC Quality of Life (QoL) Questionnaire (EORTC QLQ-C30) (Mexican version) before beginning radiotherapy and one month later. Results The overall response rate (ORR) was 54% for the CLQ arm and 55% for the control arm (p=0.92). The progression-free survival of brain metastases (BMPFS) rates at one year were 83.9% (95% CI 69.4-98.4) for the CLQ arm and 55.1% (95% CI 33.6-77.6) for the control arm. Treatment with CLQ was independently associated with increased BMPFS (RR 0.31,95% CI [0.1-0.9], p=0.046).The only factor that was independently associated with increased overall survival (OS) was the presence of< 4 brain metastases (RR 1.9, 95% CI [1.12-3.3], p=0.017). WBI was associated with improvements in cognitive and emotional function but also with worsened nausea in both patients groups. No differences in QoL or toxicity were found between the study arms. Conclusion Treatment with CLQ plus WBI improved the control of BM (compared with the control arm) with no increase in toxicity; however, CLQ did not improve the RR or OS. A phase III clinical trial is warranted to confirm these findings.

Abstract
Metastasis to the central nervous system (CNS) is a devastating neurological complication of systemic cancer. Brain metastases from breast cancer have been documented to occur in approximately 10%-16% of cases over the natural course of the disease with leptomeningeal metastases occurring in approximately 2%-5% of cases of breast cancer. CNS metastases among women with breast cancer tend to occur among those who are younger, have larger tumors, and have a more aggressive histological subtype such as the triple negative and HER2-positive subtypes. Treatment of CNS metastases involves various combinations of whole brain radiation therapy, surgery, stereotactic radiosurgery, and chemotherapy. We will discuss the progress made in the treatment and prevention of breast cancer-associated CNS metastases and will delve into the biological underpinnings of CNS metastases including evaluating the role of breast tumor subtype on the incidence, natural history, prognostic outcome, and impact of therapeutic efficacy.

Abstract
Brain metastases from primary lung cancer represent 40% of all brain metastases. On the other hand, 10 to 80% of primary lung cancer patients will present with synchronous or metachronous brain metastases. Management of these patients is therefore a big challenge. The management will depend on the circumstances of diagnosis (symptomatic or not), the cancer history (synchronous or metachronous brain metastases), the histology and the number of lesions.

Abstract
OBJECTIVE To assess the frequency of brain metastasis in patients with primary esophageal cancer and to describe the clinical characteristics, diagnosis, and prognosis. METHODS Of 1612 patients with primary esophageal carcinoma treated at a single institution from 2000-2010, a retrospective analysis of the medical files of 26 consecutive patients with central nervous system involvement was carried out. The clinical history, imaging, and pathologic findings were analyzed. RESULTS Of the 26 patients, 12 initially presented with a single cerebral metastatic lesion, and 14 had multiple brain lesions. There were 4 patients with adenocarcinoma and 22 with squamous cell carcinoma. Treatments were as follows: 5 patients underwent surgery followed by whole-brain radiation, 5 underwent stereotactic radiosurgery, 13 received whole-brain radiation, and 3 received chemotherapy. The median survival was 4.2 months; 1-year survival rate was 5.8%. CONCLUSIONS In this retrospective study of 1612 patients with esophageal carcinoma at a single medical center, 1.61% (26 of 1612) of the patients had a diagnosis of brain metastasis. The prognosis is poor for patients with brain metastasis from esophageal carcinoma. A solitary brain lesion, surgical treatment, and a good Karnofsky Performance Status may indicate a good prognosis.

Abstract
PURPOSE OF REVIEW To summarize developments in the management of brain metastases over the past decade. RECENT FINDINGS A few randomized trials have been published during the past decade examining the use of whole brain radiotherapy (WBRT) and radiosurgery (SRS) boost versus WBRT alone. Other recent trials have been published examining the use of SRS alone versus SRS and WBRT.There continues to be neither a role for the routine use of chemotherapy (excluding patients with metastatic seminoma to brain) nor radiosensitizers in the management of patients with brain metastases. SUMMARY The management options for selected patients with brain metastases today include steroids (to treat brain edema), anticonvulsants (to treat seizures), WBRT, surgery (for single brain metastasis) and radiosurgery (SRS), either alone or in combination. Survival, local metastasis control, overall brain control, and neuro-cognitive outcomes should influence management. New therapeutic areas of research for brain metastases include defining the role of conventional and novel chemotherapy and targeted agents, radiation sensitizers, and stem cell-associated therapies either alone or in combination with various forms of radiation, as well as decreasing radiation morbidities, using drugs or technology.

Abstract
BACKGROUND Brain metastases represent a significant healthcare problem. It is estimated that 20% to 40% of patients with cancer will develop metastatic cancer to the brain during the course of their illness. The burden of brain metastases impacts on quality and length of survival. Presenting symptoms include headache (49%), focal weakness (30%), mental disturbances (32%), gait ataxia (21%), seizures (18%), speech difficulty (12%), visual disturbance (6%), sensory disturbance (6%) and limb ataxia (6%).Brain metastases may spread from any primary site. The most common primary site is the lung, followed by the breast then gastrointestinal sites. Eighty-five per cent of brain metastases are found in the cerebral hemispheres, 10% to 15% in the cerebellum and 1% to 3% in the brainstem. Brain radiotherapy is used to treat cancer participants who have brain metastases from various primary malignancies.This is an update to the original review published in Issue 3, 2006. OBJECTIVES To assess the effectiveness and adverse effects of whole brain radiotherapy (WBRT) in adult participants with multiple metastases to the brain. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 3, 2011), MEDLINE and EMBASE to July 2011. SELECTION CRITERIA Randomized controlled trials (RCTs) comparing WBRT either alone or with other treatments in adults with newly diagnosed multiple metastases to the brain from any primary cancer. Trials of prophylactic WBRT were excluded as well as trials that dealt with surgery or WBRT, or both, for the treatment of single brain metastasis. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and abstracted information. Adverse effects information was also collected from the trials. MAIN RESULTS Nine RCTs involving 1420 participants were added in this updated review. This updated review now includes a total of 39 trials involving 10,835 participants.Eight published reports (nine RCTs) showed no benefit of altered dose-fractionation schedules as compared to the control fractionation (3000 cGy in 10 fractions daily) of WBRT for overall survival. These studies also showed no improvement in symptom control nor neurologic improvement among the different dose-fractionation schemes as compared to 3000 cGy in 10 daily fractions of WBRT. This updated review includes two trials comparing 4000 cGy in 20 fractions given twice daily versus 2000 cGy in 4 or 5 daily fractions. Overall, there was no survival advantage (hazard ratio (HR) 1.18, 95% confidence interval (CI) 0.89 to 1.56, P = 0.25) with the use of 4000 cGy in 20 fractions given twice daily compared to 2000 cGy in 4 or 5 daily fractions.The addition of radiosensitizers in six RCTs did not confer additional benefit to WBRT in either the overall survival times (HR 1.08, 95% CI 0.98 to 1.18, P = 0.11) or brain tumour response rates (HR 0.87, 95% CI 0.60 to 1.26, P = 0.46).Two RCTs found no benefit in overall survival (HR 0.61, 95% CI 0.27 to 1.39, P = 0.24) with the use of WBRT and radiosurgery boost as compared to WBRT alone for selected participants with multiple brain metastases (up to four brain metastases). Overall, there was a statistically significant improvement in local brain control (HR 0.35, 95% CI 0.20 to 0.61, P = 0.0003) favouring the WBRT and radiosurgery boost arm. Only one trial of radiosurgery boost with WBRT reported an improved Karnofsky performance score outcome and improved ability to reduce the dexamethasone dose.In this updated review, a total of three RCTs reported on selected patients (with up to three or four brain metastases) treated with radiosurgery alone versus WBRT and radiosurgery. Based on two trials, there was no difference in overall survival (HR 0.98, 95% CI 0.71 to 1.35, P = 0.88). The addition of WBRT when added to radiosurgery significantly improved locally treated brain metasatases control (HR 2.61, 95% CI 1.68 to 4.06, P < 0.0001) and distant brain control (HR 2.15, 95% CI 1.55 to 2.99, P < 0.00001). On the other hand, one trial concluded that patients treated with WBRT and radiosurgery boost were significantly more likely to show a decline in learning and memory function as compared to those treated with radiosurgery alone.One RCT examined the use of WBRT and prednisone versus prednisone alone and produced inconclusive results. AUTHORS' CONCLUSIONS None of the RCTs with altered WBRT dose-fractionation schemes as compared to standard (3000 cGy in 10 daily fractions or 2000 cGy in 4 or 5 daily fractions) found a benefit in terms of overall survival, neurologic function, or symptom control.The use of radiosensitizers or chemotherapy in conjunction with WBRT remains experimental.Radiosurgery boost with WBRT may improve local disease control in selected participants as compared to WBRT alone, although survival remains unchanged for participants with multiple brain metastases.This updated review now includes a total of three RCTs examining the use of radiosurgery alone versus WBRT and radiosurgery. The addition of WBRT to radiosurgery improves local and distant brain control but there is no difference in overall survival. Patients treated with radiosurgery alone were found to have better neurocognitive outcomes in one trial as compared to patients treated with WBRT and radiosurgery.The benefit of WBRT as compared to supportive care alone has not been studied in RCTs. It may be that supportive care alone, without WBRT, is appropriate for some participants, particularly those with advanced disease and poor performance status.

Abstract
The optimal management of brain metastases remains controversial. Both whole brain radiotherapy (WBRT) and local treatment [surgery (S) or radiosurgery (RS)] are the cornerstones of treatment. The role of systemic therapy is also being explored. Randomized controlled trials (RCT) have tried to assess the individual and combined effects of different therapeutic strategies. (1) RCT in oligometastatic patients: WBRT alone vs. local treatment+WBRT. Combined treatment may improve both overall survival and local control in patients with a single metastasis, but it also leads to a local control benefit in patients with two to four lesions. Exclusive local treatment vs. WBRT plus local treatment. The addition of WBRT to local treatment may result in improved local control, improved freedom from new brain metastases and improved overall brain control. S+WBRT vs. RS+WBRT. There is no evidence of superiority of a combined treatment over the other one. (2) RCT addressing the point of improving WBRT outcome: differences in WBRT fractionation do not significantly alter outcome of treatments. Only a few systemic drugs may cause some significant advantages. (3) RCT that assessed neurocognitive impairment and quality of life: the baseline cognitive performance of most patients is significantly impaired. Intracranial tumor control is an essential factor in stabilizing neurocognitive function. The data on neurocognitive toxicity related to WBRT are still contradictory. Impairment of both neurocognitive function and quality of life of patients with brain metastases needs to be further addressed in RCT.

Abstract
PURPOSE OF REVIEW This review provides available clinical evidence regarding current therapies, discusses ongoing controversies, and introduces investigational approaches in the management of brain metastases. RECENT FINDINGS Novel approaches to estimating prognosis of patients with brain metastases highlight the importance of tailoring treatment to each particular patient. In the setting of unfavorable prognosis, either hospice care, symptom management, or short-course whole-brain radiotherapy (WBRT) is a critical component of palliation. In the setting of favorable or intermediate prognosis, treatment options can include a slightly more prolonged course of WBRT, surgery, stereotactic radiosurgery, systemic therapy, or a combination. Selection of the appropriate treatment is influenced by the number of brain metastases, overall patient performance status and residual life expectancy, as well as an understanding of the benefits and toxicities of each modality. Recent clinical studies have shed novel insight on the temporal sequence of memory changes following WBRT. Innovative approaches to mitigating these radiation-induced memory effects are currently being investigated. SUMMARY Evidence-based management of brain metastases represents an evolving field of active clinical research. Ongoing and future investigations focus on the preservation of cognition and quality of life, in addition to conventional outcomes such as intracranial tumor control and survival.

Abstract
The concept of clinical trial feasibility is of great interest to the community of palliative care researchers, clinicians, and granting agencies. Significant allocation of resources is required in the form of funding, time, intellect, and motivation to carry out clinical research, and understandably, clinical investigators, institutions, and granting agencies are disappointed when funded trials are unsuccessfully conducted. We argue that for many trials conducted in palliative care, the feasibility of conducting the proposed trial should be formally explored before implementation. There is substantial information available within the literature on the topic of study feasibility but no singular guide on how one can pragmatically apply this advice in the palliative care setting. We suggest that a Formal Feasibility Study for palliative care trials should be commonly conducted before development of a larger pivotal trial, to prospectively identify barriers to research, develop strategies to address these barriers, and predict whether the larger study is feasible. If a Formal Feasibility Study is not required, elements of feasibility can be specifically tested before launching clinical trials. The purpose of this article is to offer a draft framework for the design and conduct of a Formal Feasibility Study that, if implemented, could concretely support successful completion of high-quality research in a timely fashion. Additionally, we hope to foster dialogue within the palliative care research community regarding the relevance of establishing feasibility before initiation of definitive trials in the palliative care population.

Abstract
Brain metastases are not only the most common intracranial neoplasm in adults but also very prevalent in patients with lung cancer. Patients have been grouped into different classes based on the presence of prognostic factors such as control of the primary tumor, functional performance status, age, and number of brain metastases. Patients with good prognosis may benefit from more aggressive treatment because of the potential for prolonged survival for some of them. In this review, we will comprehensively discuss the therapeutic options for treating brain metastases, which arise mostly from a lung cancer primary. In particular, we will focus on the patient selection for combined modality treatment of brain metastases, such as surgical resection or stereotactic radiosurgery (SRS) combined with whole brain irradiation; the use of radiosensitizers; and the neurocognitive deficits after whole brain irradiation with or without SRS. The benefit of prophylactic cranial irradiation (PCI) and its potentially associated neuro-toxicity for both small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) are also discussed, along with the combined treatment of intrathoracic primary disease and solitary brain metastasis. The roles of SRS to the surgical bed, fractionated stereotactic radiotherapy, WBRT with an integrated boost to the gross brain metastases, as well as combining WBRT with epidermal growth factor receptor (EGFR) inhibitors, are explored as well.

Abstract
This study sought to establish the recommended phase II dose and efficacy of temozolomide (TMZ) with concurrent radiotherapy in patients with brain metastases. Patients were stratified by prior systemic therapy (≤1 vs. ≥2) and enrolled in cohorts of escalating doses of daily TMZ for 14 days (group A: 75, 95, 115, 135, or 150 mg/m(2), group B: 75, 90, 105, 120, or 135 mg/m(2)). Endpoints included safety and clinical activity. For group A (≤1 prior chemotherapy) no dose limiting toxicity was seen at 75 and 95 mg/m(2). Five of eight patients experienced dose limiting toxicities at 115 mg/m(2), thus the recommended phase II dose was 95 mg/m(2). Arm B (≥2 prior chemotherapy regimens) was closed due to poor enrollment. In the phase II portion, 17 patients in group A were treated. There were 0 patients with complete radiographic response, three with a partial response, ten remained stable, and four demonstrated early progression. The 3 and 6 month progression-free survival (PFS) rates were 41 and 18% with a median PFS time of 2.4 months. Overall survival at 3 and 6 months was 53 and 41%, respectively, with a median survival time of 4.1 months. The maximum tolerated dose of daily TMZ with concurrent WBRT was 95 mg/m(2). Despite dose escalation, outcomes did not appear to be improved in the sample treated.

Mulvenna PM. The management of brain metastases in patients with non-small cell lung cancer-is it time to go back to the drawing board? Clin Oncol (R Coll Radiol) 2010; 22:365-73. [PMID: 20395118 DOI: 10.1016/j.clon.2010.03.011] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2010] [Revised: 03/02/2010] [Accepted: 03/18/2010] [Indexed: 10/19/2022]
Abstract
Unless confirmation of a solitary brain metastasis is made in the context of absent extracranial disease and good performance status, patients with metastatic brain disease from non-small cell lung cancer fare badly. There are no level I recommendations for the management of those with multiple brain metastases. The role of whole brain radiotherapy is not certain in those of poorer performance status. This overview assesses what we know and what we are uncertain of in the context of a changing paradigm for some subsets of patients who may obtain superior palliation with treatments targeted at the histological or molecular level. Once the standard treatment is established (steroids plus or minus whole brain radiotherapy), those who are of better performance status may be considered for comparison of this standard with or without systemic management.
