First-line chemoimmunotherapy and immunotherapy in patients with non-small cell lung cancer and brain metastases: a registry study. Front Oncol 2024; 14:1305720. [PMID: 38406805 PMCID: PMC10885799 DOI: 10.3389/fonc.2024.1305720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Accepted: 01/08/2024] [Indexed: 02/27/2024] Open
Abstract
Introduction Brain metastases commonly occur in patients with non-small cell lung cancer (NSCLC). Standard first-line treatment for NSCLC, without an EGFR, ALK or ROS1 mutation, is either chemoimmunotherapy or anti-PD-1 monotherapy. Traditionally, patients with symptomatic or untreated brain metastases were excluded from the pivotal clinical trials that established first-line treatment recommendations. The intracranial effectiveness of these treatment protocols has only recently been elucidated in small-scale prospective trials. Methods Patients with NSCLC and brain metastases, treated with first-line chemoimmunotherapy or anti-PD-1 monotherapy were selected from the Australian Registry and biObank of thoracic cancers (AURORA) clinical database covering seven institutions. The primary outcome was a composite time-to-event (TTE) outcome, including extracranial and intracranial progression, death, or need for local intracranial therapy, which served as a surrogate for disease progression. The secondary outcome included overall survival (OS), intracranial objective response rate (iORR) and objective response rate (ORR). Results 116 patients were included. 63% received combination chemoimmunotherapy and 37% received anti-PD-1 monotherapy. 69% of patients received upfront local therapy either with surgery, radiotherapy or both. The median TTE was 7.1 months (95% CI 5 - 9) with extracranial progression being the most common progression event. Neither type of systemic therapy or upfront local therapy were predictive of TTE in a multivariate analysis. The median OS was 17 months (95% CI 13-27). Treatment with chemoimmunotherapy was predictive of longer OS in multivariate analysis (HR 0.35; 95% CI 0.14 - 0.86; p=0.01). The iORR was 46.6%. The iORR was higher in patients treated with chemoimmunotherapy compared to immunotherapy (58% versus 31%, p=0.01). The use of chemoimmunotherapy being predictive of iORR in a multivariate analysis (OR 2.88; 95% CI 1.68 - 9.98; p=0.04). Conclusion The results of this study of real-world data demonstrate the promising intracranial efficacy of chemoimmunotherapy in the first-line setting, potentially surpassing that of immunotherapy alone. No demonstrable difference in survival or TTE was seen between receipt of upfront local therapy. Prospective studies are required to assist clinical decision making regarding optimal sequencing of local and systemic therapies.

Abstract
Purpose The purpose of this study was to evaluate overall survival after systemic therapy, largely chemotherapy, in patients with small cell or non-small cell lung cancer and brain metastases. After completion of systemic therapy, some patients received planned brain irradiation, while others were followed. Methods Retrospective cohort study. Results Thirty-eight patients were included (28 small cell, 20 followed with imaging). Six of these 20 patients (30%) received delayed radiotherapy during follow-up. Planned radiotherapy (n = 18, intention-to-treat) was associated with longer survival from diagnosis of brain metastases, median 10.8 versus 6.1 months, p = 0.025. Delayed radiotherapy still resulted in numerically better survival than no radiotherapy at all (median 8.8 versus 5.3 months, not significant). If calculated from the start of delayed radiotherapy, median survival was only 2.7 months. In a multivariable analysis, both Karnofsky performance status ≥ 70 (p = 0.03) and planned radiotherapy (p = 0.05) were associated with better survival. Conclusion In patients ineligible for targeted agents, planned radiotherapy in a modern treatment setting was associated with longer survival compared to no radiotherapy. Timing and type of radiotherapy in such patients should be evaluated in prospective trials to identify patients who might not need planned radiotherapy.

Abstract
PURPOSE To provide guidance to clinicians regarding therapy for patients with brain metastases from solid tumors. METHODS ASCO convened an Expert Panel and conducted a systematic review of the literature. RESULTS Thirty-two randomized trials published in 2008 or later met eligibility criteria and form the primary evidentiary base. RECOMMENDATIONS Surgery is a reasonable option for patients with brain metastases. Patients with large tumors with mass effect are more likely to benefit than those with multiple brain metastases and/or uncontrolled systemic disease. Patients with symptomatic brain metastases should receive local therapy regardless of the systemic therapy used. For patients with asymptomatic brain metastases, local therapy should not be deferred unless deferral is specifically recommended in this guideline. The decision to defer local therapy should be based on a multidisciplinary discussion of the potential benefits and harms that the patient may experience. Several regimens were recommended for non-small-cell lung cancer, breast cancer, and melanoma. For patients with asymptomatic brain metastases and no systemic therapy options, stereotactic radiosurgery (SRS) alone should be offered to patients with one to four unresected brain metastases, excluding small-cell lung carcinoma. SRS alone to the surgical cavity should be offered to patients with one to two resected brain metastases. SRS, whole brain radiation therapy, or their combination are reasonable options for other patients. Memantine and hippocampal avoidance should be offered to patients who receive whole brain radiation therapy and have no hippocampal lesions and 4 months or more expected survival. Patients with asymptomatic brain metastases with either Karnofsky Performance Status ≤ 50 or Karnofsky Performance Status < 70 with no systemic therapy options do not derive benefit from radiation therapy.Additional information is available at www.asco.org/neurooncology-guidelines.

Abstract
BACKGROUND/AIM We examined the difference between whole-brain radiation therapy (WBRT) for intracranial metastases (IM) from lung cancer as an initial and as a late treatment affecting overall survival (OS). PATIENTS AND METHODS Thirty-three patients who presented with IM at initial examination who received WBRT as the initial treatment (initial WBRT group) and 47 patients without IM or with asymptomatic IM at initial examination who received WBRT after systemic therapy, between January 2014 and December 2020, were retrospectively analyzed. Patients' OS after WBRT were compared. RESULTS Median OS was significantly longer in patients treated with systemic anticancer therapy after WBRT than in patients who were not (176 vs. 47 days, respectively; p<0.001), and systemic anticancer therapy after WBRT was a significant prognostic factor (p<0.001). CONCLUSION Treatment with systemic anticancer therapy after WBRT may prolong the survival of patients who present with IM at initial examination.

Abstract
Background: The role and timing of whole or stereotaxic brain radiotherapy (BR) in patients with advanced non-small cell lung cancer (aNSCLC) and asymptomatic brain metastases (aBMs) are not well established. This study investigates whether deferring BR until cerebral progression was superior to upfront BR for patients with aNSCLC and aBM. Methods: This open-label, multicenter, phase III trial, randomized (1:1) aNSCLC patients with aBMs to receive upfront BR and chemotherapy: platin–pemetrexed and bevacizumab in eligible patients, followed by maintenance pemetrexed with or without bevacizumab, BR arm, or the same chemotherapy with BR only at cerebral progression, chemotherapy (ChT) arm. Primary endpoint was progression-free survival (PFS), secondary endpoints were overall survival (OS), global, extra-cerebral and cerebral objective response rate (ORR), toxicity, and quality of life [ClinicalTrials.gov identifier: NCT02162537]. Results: The trial was stopped early because of slow recruitment. Among 95 included patients, 91 were randomized in 24 centers: 45 to BR and 46 to ChT arms (age: 60 ± 8.1, men: 79%, PS 0/1: 51.7%/48.3%; adenocarcinomas: 92.2%, extra-cerebral metastases: 57.8%, without differences between arms.) Significantly more patients in the BR-arm received BR compare with those in the ChT arm (87% versus 20%; p < 0.001); there were no significant differences between BR and ChT arms for median PFS: 4.7, 95% confidence interval (CI):3.4–7.5 versus 4.8, 95% CI: 2.4–6.5 months, for median OS: 8.5, 95% CI:.6–11.1 versus 8.3, 95% CI:4.5–11.5 months, cerebral and extra-cerebral ORR (27% versus 13%, p = 0.064, and 30% versus 41%, p = 0.245, respectively). The ChT arm had more grade 3/4 neutropenia than the BR arm (13% versus 6%, p = 0.045); others toxicities were comparable. Conclusion: The significant BR rate difference between the two arms suggests that upfront BR is not mandatory in aNSCLC with aBM but this trial failed to show that deferring BR for aBM is superior in terms of PFS from upfront BR.

Abstract
PURPOSE OF REVIEW Management of metastasis to the central nervous system (CNS) has evolved, and molecular characterization of metastatic disease is now routinely done. Targeted therapies, once few in number with limited penetration into the CNS, have multiplied in number and increased in CNS coverage. This article addresses recent advances in the evaluation and clinical management of patients with CNS metastasis. RECENT FINDINGS Metastasis of cancer to the CNS can be diagnosed and characterized with novel techniques, including molecular analyses of the spinal fluid, so-called liquid biopsies. Resected parenchymal CNS metastases are now routinely subjected to genomic sequencing. For patients with CNS metastases displaying targetable mutations, a wide variety of treatment options are available, including deferral of radiation therapy in favor of a trial of an orally bioavailable targeted therapy or immunotherapy. For patients without a molecularly targetable lesion, local treatment in the form of radiation therapy, now most often stereotactic radiosurgery, is supplanting untargeted whole-brain radiation therapy. SUMMARY Technologic advances in diagnosis and management have resulted in new diagnostic and therapeutic approaches to patients with metastasis to the CNS, with resulting improvements in progression-free and overall survival.

Abstract
Central nervous system (CNS) metastases occur frequently in oncogene-driven non-small cell lung cancer (NSCLC). Standard treatment approaches can potentially delay systemic treatment (surgical intervention) or result in neurocognitive impairment (radiotherapy). Recently, next-generation tyrosine kinase inhibitors (TKIs) have demonstrated remarkable intracranial activity. However, most clinical trials did not enroll patients suffering neurological symptoms. Our study aimed to assess the CNS activity of targeted therapies in this patient population. We present a case series of nine NSCLC patients with either EGFR mutation or ALK rearrangement and symptomatic CNS metastases that were treated with TKIs. Clinicopathological characteristics, treatment, and outcomes were analyzed. Most patients presented with symptomatic CNS metastases at time of metastatic disease presentation (6/9). Additionally, the majority of patients had leptomeningeal disease (6/9) and multiple parenchymal metastases. Patients presented with a variety of CNS symptoms with the most common being nausea, vomiting, headache, and confusion. Most patients (6/9) responded rapidly both clinically and radiographically to the targeted treatment, with a marked correlation between systemic and intracranial radiographic response. In conclusion, upfront use of next-generation TKIs in patients with oncogene-driven NSCLC with symptomatic CNS metastases is associated with reasonable intracranial activity and represents a valuable treatment option.

Abstract
Preferable treatments for epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) with brain metastasis are elusive. The study intended to estimate the relative efficacy and safety of systemic therapies. Clinical trials about therapies for EGFR-mutant, brain-metastatic NSCLC were identified. Progression-free survival (PFS) and overall survival (OS) were analysed using random effects Bayesian network meta-analyses (NMAs) on the hazard ratio (HR)-scale. Nomogram and Kaplan-Meier plots based on clinical or individual factors are displayed using data obtained from the Surveillance Epidemiology and End Results (SEER) database. Third-generation EGFR- tyrosine kinase inhibitors (EGFR-TKI) (osimertinib), EGFR-TKIs + stereotactic radiosurgery (SRS)/whole brain radiotherapy (WBRT) (gefitinib/erlotinib + SRS/WBRT), and EGFR-TKIs (erlotinib) + anti-vascular endothelial growth factor receptor (anti-VEGFR) (bevacizumab) achieved superior PFS (HR: 0.30 (0.15-0.59); HR: 0.47 (0.31-0.72); HR: 0.50 (0.21-1.21) vs. deferring SRS/WBRT) and acceptability; EGFR-TKIs + SRS/WBRT was top ranking (vs. others) for OS followed by third-generation EGFR-TKI. In the dataset cohort of 1173 brain-metastatic NSCLC patients, the 6-month, 1-year, and 3-year survival rates were 59.8%, 41.3%, and 5.6%, respectively. Race and origin, and year of diagnosis were independent predictors of OS. Survival curves showed that the OS of patients varied significantly by histology and race. Third-generation EGFR-TKI and EGFR-TKIs + SRS/WBRT are more effective and potentially acceptable for EGFR-mutant NSCLC with brain metastases balancing OS and PFS. Surgeries without adjuvant therapies cannot significantly improve the OS of brain-metastatic NSCLC patients. The study highlights importance of osimertinib in these patients and provide a reference for clinical treatments.

Abstract
Brain metastases (BrMs) are associated with significant morbidity and are found in up to 50% of patients with advanced non-small cell lung cancer (NSCLC). Most of the literature focuses on symptomatic BrMs, with a lack of baseline brain imaging in asymptomatic patients. Unfortunately, much of the data on local treatments with or without systemic treatment is retrospective. Clinical trials of systemic treatments largely exclude patients with BrMs. Chemotherapy is an active treatment for BrM with response rates in the brain similar to other sites of disease. Targeted systemic treatments in patients with driver mutations (EGFR and ALK-MET to date) have impressive central nervous system (CNS) penetrance and response rates. Unfortunately, no prospective data can currently guide the timings or modality of local therapies with systemic treatments in these patients who have a high incidence of CNS disease, but retrospective data suggest that early local therapies may give better intracranial progression-free survival (ICPFS). Recent immunotherapy trials have included patients with BrMs. These patients have largely been pre-treated with local therapies and are asymptomatic. Thus, the current standard is becoming, early local therapies before or in conjunction with immunotherapy agents. The approach seems to be safe. Prospective studies are needed in NSCLC BrMs patients to make sure any benefit from local therapies on the ICPFS and quality of life is not overlooked. Here we report what we think are reasonable conclusions from the available data and make suggestions for future clinical trials in the management of NSCLC BrMs.

Number of metastatic organs negatively affects the treatment sequence in patients with EGFR-TKI failure. Thorac Cancer 2020; 11:1038-1044. [PMID: 32077630 PMCID: PMC7113048 DOI: 10.1111/1759-7714.13360] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Revised: 01/30/2020] [Accepted: 01/31/2020] [Indexed: 11/27/2022] Open
Abstract
Background Several studies have previously demonstrated the survival benefit of both EGFR‐TKI treatment and chemotherapy in patients with non‐small cell lung cancer (NSCLC) harboring EGFR mutations. The aim of the present study was to clarify the factors influencing the treatment sequence after failure of EGFR‐TKI therapy, focusing on the number of organs with metastasis (hereafter, metastatic organs). Methods Between January 2010 and December 2016, consecutive patients with EGFR‐mutated NSCLC who were started on first‐line EGFR‐TKI were reviewed. The factors influencing withholding systemic chemotherapy and the post‐progression survival (PPS) after failure of EGFR‐TKI were investigated. Results A total of 393 patients were started on first‐line EGFR‐TKI during the study period. After excluding patients maintained on EGFR‐TKI or who received osimertinib targeting secondary EGFR T790M, 297 patients were included in the analysis. Among these, 180 (60.6%) received chemotherapy after failure of EGFR‐TKI (TKI‐Ct group), while the remaining 117 (39.4%) received no chemotherapy (TKI‐only group). Multivariate analysis identified older age (≥75 years: odds ratio [OR] = 0.25, 95% confidence interval [CI]: 0.11–0.43, P < 0.001), poor performance status (PS) (≥2: OR = 0.06, 95% CI: 0.03–0.15, P < 0.001), and three or more metastatic organs (OR = 0.42, 95% CI: 0.22–0.80, P = 0.008) as being significantly associated with withholding of chemotherapy after failure of EGFR‐TKI. Conclusion A relatively large number of metastatic organs and a poor PS were associated with the withholding of subsequent chemotherapy after failure of EGFR‐TKI in EGFR‐mutated NSCLC patients. Further research for patients with such a poor prognosis should be investigated in the future.

Abstract
QUESTION 1 Should patients with brain metastases receive chemotherapy in addition to whole brain radiotherapy (WBRT) for the treatment of their brain metastases? TARGET POPULATION This recommendation applies to adult patients with newly diagnosed brain metastases amenable to both chemotherapy and radiation treatment. RECOMMENDATIONS Level 1: Routine use of chemotherapy following WBRT for brain metastases is not recommended. Level 3: Routine use of WBRT plus temozolomide is recommended as a treatment for patients with triple negative breast cancer. QUESTION 2 Should patients with brain metastases receive chemotherapy in addition to stereotactic radiosurgery (SRS) for the treatment of their brain metastases? RECOMMENDATIONS Level 1: Routine use of chemotherapy following SRS is not recommended. Level 2: SRS is recommended in combination with chemotherapy to improve overall survival and progression free survival in lung adenocarcinoma patients. QUESTION 3 Should patients with brain metastases receive chemotherapy alone? RECOMMENDATION Level 1: Routine use of cytotoxic chemotherapy alone for brain metastases is not recommended as it has not been shown to increase overall survival.Please see the full-text version of this guideline (https://www.cns.org/guidelines/guidelines-treatment-adults-metastatic-brain-tumors/chapter_5) for the target population of each recommendation.

Abstract
INTRODUCTION Thirty per cent of cancer patients develop brain metastases, with multiple combination or sequential treatment modalities available, to treat systemic or central nervous system (CNS) disease. Most patients experience toxicities as a result of these treatments, of which cognitive impairment is one of the adverse events most commonly reported, causing major impairment of the patient's quality of life. Areas covered: This article reviews the role of cancer treatments in cognitive decline of patients with brain metastases: surgery, radiotherapy, chemotherapy, targeted therapies, immunotherapies and hormone therapy. Pathological and molecular mechanisms, as well as future directions for limiting cognitive toxicities are also presented. Other causes of cognitive impairment in this population are discussed in order to refine the benefit-risk balance of each treatment modality. Expert opinion: Cumulative cognitive toxicity should be taken into account, and tailored to the patient's cognitive risk in the light of the expected survival benefit. Standardization of cognitive assessment in this context is needed in order to better appreciate each treatment's responsibility in cognitive impairment, keeping in mind disease itself impacts cognition in this context.

Differences in tumor microenvironments between primary lung tumors and brain metastases in lung cancer patients: therapeutic implications for immune checkpoint inhibitors. BMC Cancer 2019; 19:19.

Abstract
Background We aimed to compare intra- and extracranial responses to immune checkpoint inhibitors (ICIs) in lung cancer with brain metastases (BM), and to explore tumor microenvironments of the brain and lungs focusing on the programmed cell death-1 (PD-1)/programmed cell death ligand-1 (PD-L1) pathway. Methods Two cohorts of lung cancer patients with BM were analyzed. Cohort 1 included 18 patients treated with nivolumab or pembrolizumab, and intra- and extracranial responses were assessed. Cohort 2 comprised 20 patients who underwent both primary lung surgery and brain metastasectomy. Specimens from cohort 2 were subjected to immunohistochemical analysis for the following markers: CD3, CD4, CD8, FOXP3, and PD-1 on tumor infiltrating lymphocytes (TIL) and PD-L1 on tumor cells. Results Seven patients (38.9%) in cohort 1 showed progressive disease in both primary and intracranial lesions. Although the other 11 patients exhibited a partial response or stable disease in the primary lesion, eight showed a progression in BM. Interestingly, PD-1+ TILs were significantly decreased in BM (P = 0.034). For fifteen patients with adenocarcinoma, more distinctive patterns were observed in CD3+ (P = 0.078), CD8+ (P = 0.055), FOXP3+ (P = 0.016), and PD-1+ (P = 0.016) TILs. Conclusions There may be discordant responses to an ICI of lung cancer between primary lung lesion and BM based on discrepancies in the tumor microenvironment. The diminished infiltration of PD-1+ TILs in tumor tissue within the brain may be one of the major factors that hinder the response to anti–PD-1 antibody in BM.

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
Brain metastases (BM) continue to represent an unmet clinical need in oncology. Immunotherapy and targeted therapy hold great promise in the treatment of BM. Emerging data are confirming the activity of these agents in patients with BM. Genomic studies have confirmed that clinically actionable mutations are present in BM and they can be used in clinical studies to link targeted therapies with their genetic targets. Furthermore, as molecular signatures associated with sensitivity and resistance to immunotherapies are developed, we will better be able to select BM patients who will most benefit from these therapies. Understanding the genetic and immune evolution within BM should drive the next generation of immunotherapy and target therapy, as well as increase the accuracy of the selection process for these therapies.

Abstract
BACKGROUND 20-40% of patients with malignant tumors have one or more brain metastases in the course of their illness. Brain metastases are the first manifestation of cancer in 5-10%. Manifestations such as intracranial hypertension or focal neurologic deficits are seen in over 80% of patients with brain metastases. Uncertainty surrounds the treatment of patients with intracranial metastases, as the existing data are derived from trials with low levels of evidence. METHODS This article is based on a selective literature review and on the authors' own experience of 100 consecutive patients who underwent surgery at the Department of Neurosurgery at Ruhr University Bochum (RUB), Germany. RESULTS Multimodal treatment enables successful surgery for an increasing number of patients with brain metastases. The modalities and goals of treatment are established for each patient individually by an interdisciplinary tumor board. Drug therapy is usually indicated. Surgical resection followed by stereotactic radiotherapy prolongs mean survival by 3-6 months and lowers the risk of recurrence from 40% to 12.5%. In the authors' own experience, even seriously ill patients can benefit from the resection of brain metastases. The 30-day morbidity was 29%, accounted for mainly by medical complications such as pulmonary embolism, renal failure, and sepsis. CONCLUSION Through the close interdisciplinary collaboration of neurosurgeons, radiation oncologists, and medical oncologists, the symptomatic state and the prognosis of patients with brain metastases can be improved. Longer overall survival implies that further studies will have to pay special attention to the toxicity of treatment.

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
Central nervous system metastases cause grave morbidity in patients with advanced malignancies. Lung cancer, breast cancer, and melanoma are the three most common causes of brain metastases. Although the exact incidence of brain metastases is unclear, there appears to be an increasing incidence which has been attributed to longer survival, better control of systemic disease, and better imaging modalities. Until recently surgical resection of solitary or symptomatic brain metastases, and radiation therapy (either whole-brain radiation therapy or stereotactic radiation) were the mainstay of treatment for patients with brain metastases. The majority of traditional chemotherapies have shown limited activity in the central nervous system, which has been attributed to the blood-brain barrier and the molecular structure of the used agents. The discovery of driver mutations and drugs targeting these mutations has changed the treatment landscape. Several of these targeted small-molecule tyrosine kinase inhibitors do cross the blood-brain barrier and/or have shown activity in the central nervous system. Another major advance in the care of brain metastases has been the advent of new immunotherapeutic agents, for which initial studies have shown intracranial activity. In this chapter, we will review the unique challenges in the treatment of brain metastases. The pertinent clinical studies of chemotherapy in brain metastases will be discussed. The currently reported clinical trials and evidence for use of targeted therapies and immunotherapeutic agents will be emphasized.

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
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
Brain metastases (BMs) will develop in a large proportion of patients with NSCLC throughout the course of their disease. Among patients with NSCLC with oncogenic drivers, mainly EGFR activating mutations and anaplastic lymphoma receptor tyrosine kinase gene (ALK) rearrangements, the presence of BM is a common secondary localization of disease both at the time of diagnosis and at relapse. Because of the limited penetration of a wide range of drugs across the blood-brain barrier, radiotherapy is considered the cornerstone of treatment of BMs. However, evidence of dramatic intracranial response rates has been reported in recent years with targeted therapies such as tyrosine kinase inhibitors and has been supported by new insights into pharmacokinetics to increase rates of tyrosine kinase inhibitors' penetration of the cerebrospinal fluid (CSF). In this context, the combination of brain radiotherapy and targeted therapies seems relevant, and there is a strong radiobiological rationale to harness the radiosentizing effect of the drugs. Nevertheless, to date, there is a paucity of high-level clinical evidence supporting the combination of brain radiotherapy and targeted therapies in patients with NSCLC and BMs, and there are often methodological biases in reported studies, such as the lack of stratification by mutation status. Moreover, among asymptomatic patients not suitable for ablative treatment, this strategy is challenged by the promising results associated with the administration of targeted therapies alone. Herein, we review the biological rationale to combine targeted therapies and brain radiotherapy for patients with NSCLC and BMs, report the clinical data available to date, and discuss future directions to improve outcome in this group of patients.

Effects of epidermal growth factor receptor-tyrosine kinase inhibitors alone on EGFR-mutant non-small cell lung cancer with brain metastasis. Thorac Cancer 2016; 7:648-654.

Abstract
Background Epidermal growth factor receptor‐tyrosine kinase inhibitors (EGFR‐TKIs) are remarkably effective for treating EGFR‐mutant non‐small cell lung cancer (NSCLC). However, the individual role of EGFR‐TKIs in patients with brain metastasis (BM) arising from EGFR‐mutant NSCLC remains unclear. Methods Patients with BM secondary to NSCLC and harboring EGFR‐activating mutations were retrospectively screened. Patients who received gefitinib or erlotinib to control both extracranial lesions (ECLs) and intracranial lesions (ICLs) were eligible. If ECLs remained stable or remissive while ICLs progressed; asymptomatic BM progressed to symptomatic BM; BM symptoms were not alleviated within two weeks; or BM symptoms deteriorated after initial release, patients received brain radiotherapy or other local treatments and continued taking TKIs until ECLs progression occurred. Results In 43 eligible patients, the objective response and disease control rates for ICLs were 57% and 91%, respectively. Median progression‐free survival (PFS) was 9.3 months. The median PFS for ICLs and ECLs was 9.7 and 13.7 months, respectively. Non‐smokers and second‐line TKIs were found to be independent positive prognostic factors for PFS and overall survival (OS) respectively, with a hazard ratio of 0.29 (95% confidence interval [CI] 0.14–0.61; P = 0.001) and 0.34 (95% CI 0.16–0.70; P = 0.003). No significant difference in median OS was observed between patients who did or did not receive brain radiotherapy (23.6 vs. 18.7 months; P = 0.317). Conclusion EGFR‐TKIs alone are effective for treating BM arising from EGFR‐mutant NSCLC. The efficacy of TKIs in ICLs and ECLs should be evaluated separately.

Abstract
Brain metastases are common among patients with lung cancer and have been associated with significant morbidity and limited survival. However, the treatment of brain metastases has evolved as the field has advanced in terms of central nervous system imaging, surgical technique, and radiotherapy technology. This has allowed patients to receive improved treatment with less toxicity and more durable benefit. In addition, there have been significant advances in systemic therapy for lung cancer in recent years, and several treatments including chemotherapy, targeted therapy, and immunotherapy exhibit activity in the central nervous system. Utilizing systemic therapy for treating brain metastases can avoid or delay local therapy and often allows patients to receive effective treatment for both intracranial and extracranial disease. Determining the appropriate treatment for patients with lung cancer brain metastases therefore requires a clear understanding of intracranial disease burden, tumor histology, molecular characteristics, and overall cancer prognosis. This review provides updates on the current state of surgery and radiotherapy for the treatment of brain metastases, as well as an overview of systemic therapy options that may be effective in select patients with intracranial metastases from lung cancer.

Abstract
Background In this study, we investigated the efficacy of continuous epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) administration in lung adenocarcinoma patients harboring favorable mutations regarding the progressive disease (PD) status with appearance of indolent new lesions. Methods From June 2010 to October 2012, 102 patients with lung adenocarcinoma, harboring favorable EGFR mutations and treated with EGFR-TKI were analyzed. Definite new lesions were detected during EGFR-TKI therapy, even though the primary target tumors were controlled. Results Of the 102 patients, 57 continued and 45 discontinued EGFR-TKI therapy. The median overall survival was 529 days for the discontinuation group and 791 days for the continuation group (p = 0.0197). Median survival time after the discontinuation of EGFR-TKI was 181 days and 115 days in the discontinuation and continuation groups, respectively (p = 0.1776), whereas median survival time after the appearance of indolent new lesions was 204 days and 262 days, respectively (p = 0.0237). Conclusion Continuous EGFR-TKI administration in favorable EGFR-mutative lung adenocarcinoma patients with controlled primary tumors did not hinder the survival benefit, despite the appearance of new lesions.

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
PURPOSE To perform a retrospective analysis of patients with epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma who developed brain metastases (BM) to evaluate our hypothesis that the use of upfront EGFR-tyrosine kinase inhibitors (TKIs), and deferral of radiation therapy (RT), would result in inferior intracranial progression-free survival but similar overall survival (OS). METHODS AND MATERIALS Of 202 patients diagnosed with EGFR-mutant NSCLC between July 1, 2008, and December 31, 2014, 71 developed BM. Twenty-one patients were excluded owing to prior EGFR-TKI use, EGFR-TKI resistance mutation, failure to receive EGFR-TKI after whole-brain radiation therapy (WBRT)/stereotactic radiosurgery (SRS) or <6 months' follow-up. Of the remaining 50 patients, 17 received upfront EGFR-TKI followed by SRS or WBRT, 17 WBRT then EGFR-TKI, and 16 SRS followed by EGFR-TKI. Disease-specific-graded prognostic assessment was similar among all 3 groups. RESULTS The median OS was longer in the upfront RT group compared with the upfront EGFR-TKI group (34.1 vs 19.4 months; P=.01). On subgroup analysis, the SRS group had longer OS than the upfront EGFR-TKI group (58.4 vs 19.4 months; P=.01), but the WBRT group did not (29.9 vs 19.4 months; P=.09). Intracranial progression-free survival was improved in patients receiving upfront RT compared with those receiving upfront EGFR-TKI (37.9 vs 10.6 months; P<.001). CONCLUSIONS The present study suggests that the use of upfront EGFR-TKI, and the deferral of SRS or WBRT, may result in inferior OS in patients with EGFR-mutant NSCLC who develop brain metastases. A prospective, multi-institutional, randomized trial of upfront EGFR-TKI with RT at intracranial progression versus upfront RT followed by EGFR-TKI is urgently needed.

Abstract
BACKGROUND The purpose of this study is to evaluate the effect of postoperative chemotherapy on recurrence and survival in patients after resection of metastatic brain tumors from non-small cell lung cancers. METHODS Patients who went through resection of a single metastatic brain tumor from non-small cell lung cancer from July 2001 to December 2012 were reviewed. Those selected were 77 patients who survived more than 3 months after surgery were selected. Among them, 44 patients received various postoperative systemic chemotherapies, 33 patients received postoperative adjuvant whole brain radiotherapy (WBRT). Local/distant recurrence rate, local/distant recurrence free survival, disease free survival (DFS), and overall survival were compared between the two groups. RESULTS Among the 77 patients, there were 19 (24.7%) local recurrences. Local recurrence occurred in 7 (21.2%) of 33 patients in the adjuvant radiotherapy (RT) group and in 12 (27.3%) of the 44 patients in the chemotherapy group (p=0.542). Among the 77 patients, there were 34 (44.1%) distant recurrences. Distant recurrence occurred in 7 (21.2%) of the 33 patients in the adjuvant RT group and in 27 (61.4%) of the 44 patients in the chemotherapy group (p<0.0005). Patients' survival in terms of local recurrence free survival, distant recurrence free survival, DFS, and overall survival was not shown to be statistically different between the two groups before and after adjusting for covariates. CONCLUSION There was no significant difference observed between postoperative adjuvant chemotherapy and adjuvant WBRT in terms of patients' survival. Postoperative chemotherapy is more feasible and may be an appropriate option for simultaneous control of both primary and metastatic lesions.

Abstract
The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Lung Cancer 13 (QLQ-LC13) covers 13 typical symptoms of lung cancer patients and was the first module developed in conjunction with the EORTC core quality-of-life (QL) questionnaire. This review investigates how the module has been used and reported in cancer clinical trials in the 20 years since its publication. Thirty-six databases were searched with a prespecified algorithm. This search plus an additional hand search generated 770 hits, 240 of which were clinical studies. Two raters extracted data using a coding scheme. Analyses focused on the randomized controlled trials (RCTs). Of the 240 clinical studies that were identified using the LC13, 109 (45%) were RCTs. More than half of the RCTs were phase 3 trials (n = 58). Twenty RCTs considered QL as the primary endpoint, and 68 considered it as a secondary endpoint. QL results were addressed in the results section of the article (n = 89) or in the abstract (n = 92); and, in half of the articles, QL results were presented in the form of tables (n = 53) or figures (n = 43). Furthermore, QL results had an impact on the evaluation of the therapy that could be clearly demonstrated in the 47 RCTs that yielded QL differences between treatment and control groups. The EORTC QLQ-LC13 fulfilled its mission to be used as a standard instrument in lung cancer clinical trials. An update of the LC13 is underway to keep up with new therapeutic trends and to ensure optimized and relevant QL assessment in future trials.

Abstract
INTRODUCTION Central nervous system (CNS) metastases represent an important cause of morbidity and mortality in non-small cell lung cancer (NSCLC) patients. Local approaches of neurosurgery (usually for single brain lesions), whole brain radiotherapy, and stereotactic radiosurgery are often withheld for the treatment of NSCLC-derived brain metastases (BMs). However, systemic treatment is consistently emerging as an option for patients with asymptomatic BMs, which could allow for delaying cranial radiotherapy at symptomatic/radiological progression. AREAS COVERED Chemotherapy, monoclonal antibodies, tyrosine-kinase inhibitors (TKIs) for molecularly selected NSCLCs, such as epidermal growth factor receptor (EGFR)-mutant and anaplastic lymphoma kinase (ALK)-rearranged diseases, and immune checkpoint inhibitors are all systemic treatments that have shown activity against NSCLC-derived CNS metastases. Among these, EGFR- and ALK-TKIs will be discussed more in detail owing to their superior efficacy in this context. EXPERT OPINION Up-front systemic treatment should be considered for patients with asymptomatic, multiple BMs, as recently acknowledged by the European Society of Medical Oncology guidelines. Nevertheless, it must be emphasized that the best treatment strategy for NSCLC-derived BMs has to be defined within a multidisciplinary team.

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
Purpose Brain metastasis is the most common complication of brain cancer; nevertheless, primary lung cancer accounts for approximately 20%–40% of brain metastases cases. Surgical resection is the preferred treatment for brain metastases. However, no studies have reported the outcome of surgical resection of brain metastases from non–small-cell lung cancer (NSCLC) in the People’s Republic of China. Moreover, the optimal treatment for primary NSCLC in patients with synchronous brain metastases is hitherto controversial. Patients and methods We retrospectively analyzed the cases of NSCLC patients with brain metastases who underwent neurosurgical resection at the Sun Yat-sen University Cancer Center, and assessed the efficacy of surgical resection and the necessity of aggressive treatment for primary NSCLC in synchronous brain metastases patients. Results A total of 62 patients, including 47 men and 15 women, with brain metastases from NSCLC were enrolled in the study. The median age at the time of craniotomy was 54 years (range 29–76 years). At the final follow-up evaluation, 50 patients had died. The median OS time was 15.1 months, and the survival rates were 70% and 37% at 1 and 2 years, respectively. The median OS time of synchronous brain metastases patients was 12.5 months. Univariate analysis revealed that radical treatment of primary NSCLC was positively correlated with survival, and it was an independent prognostic factor in the multivariate analysis. Conclusion Surgical resection is an effective treatment for brain metastases. Besides craniotomy, radical therapy is necessary for the management of primary NSCLC in patients with synchronous brain metastases.

Abstract
This study investigated the metastatic potential of tongue squamous cell carcinoma (TSCC) cells after X-ray irradiation as well as radiation-induced changes in the biomechanical properties and cytoskeletal structure that are relevant to metastasis. Tca-8113 TSCC cells were X-ray-irradiated at increasing doses (0, 1, 2, or 4 Gy), and 24 h later, migration was evaluated with the wound healing and transwell migration assays, while invasion was assessed with the Matrigel invasion assay. Confocal and atomic force microscopy were used to examine changes in the structure of the actin cytoskeleton and Young's modulus (cell stiffness), respectively. X-ray radiation induced dose-dependent increases in invasive and migratory potentials of cells relative to unirradiated control cells (p < 0.05). The Young's modulus of irradiated cells was decreased by radiation exposure (p < 0.05), which was accompanied by alterations in the integrity and organization of the cytoskeletal network, as evidenced by a decrease in the signal intensity of actin fibers (p < 0.05). X-ray irradiation enhanced migration and invasiveness in Tca-8113 TSCC cells by altering their biomechanical properties and the organization of the actin cytoskeleton. A biomechanics-based analysis can provide an additional platform for assessing tumor response to radiation and optimization of cancer therapies.

Abstract
BACKGROUND AND PURPOSE EGFR TKIs alone have demonstrated activity against intracranial disease in EGFR mutant non-small cell lung cancer (NSCLC). This study aimed to determine if upfront cranial radiotherapy improves intracranial disease control and survival outcomes in EGFR mutant NSCLC with brain metastases relative to TKIs alone. MATERIALS AND METHODS We searched MEDLINE and various conference proceedings from 2008 to July 2014 for eligible studies where patients received upfront cranial radiotherapy or TKIs alone. Outcomes of interest were overall intracranial disease response rate (ORR), four-month intracranial disease progression-free survival (PFS), two-year overall survival (OS) and neurological adverse events (AE). We used random effects models to pool outcomes across studies and compared them using interaction tests. RESULTS We found 12 non-comparative observational studies (n=363) with severe methodological limitations. Upfront cranial radiotherapy results in similar intracranial disease ORR (relative risk (RR) 0.93, 95% confidence interval (CI) 0.82-1.06; interaction p value (p)=0.53), improved four-month intracranial disease PFS (RR 1.06, 95% CI 1.00-1.12; p=0.03), improved two-year OS (RR 1.33, 95% CI 1.00-1.77; p=0.05) but caused more neurological AEs than TKIs alone. CONCLUSION There is evidence, albeit of low quality, that upfront cranial radiotherapy may improve intracranial disease control and survival outcomes compared with TKI alone.

Abstract
OBJECTIVE This work aims to investigate the therapeutic regimen of brain metastatic cancers and the relationship between clinical features and prognosis. METHODS Clinical data of 184 patients with brain metastatic cancers were collected and analysed for the relationship between survival time and age, gender, primary diseases, quantity of brain metastatic foci, their position, extra cranial lesions, and therapeutic regimens. RESULTS The average age of onset was 59.1 years old. The median survival time (MST) was 15.0 months, and the patients with breast cancer as the primary disease had the longest survival time. Females had a longer survival time than males. Patients with meningeal metastasis had extremely short survival time. Those with less than 3 brain metastatic foci survived longer than patients with more than 3. The MST of patients receiving radiotherapy only and the patients receiving chemotherapy only were all 10.0 months while the MST of patients receiving combination therapy was 16.0 months. Multiple COX regression analysis demonstrated that gender, primary diseases, and quantity of brain metastatic foci were independent prognostic factors for brain metastatic cancers. CONCLUSIONS Chemotherapy is as important as radiotherapy in the treatment of brain metastatic cancer. Combination therapy is the best treatment mode. Male gender, brain metastatic cancers originating in the gastrointestinal tract, more than 3 metastatic foci, and involvement of meninges indicate a worse prognosis.

Abstract
Up to 50% of patients with advanced non-small-cell lung cancer will develop brain metastases at some point during their illness. These metastases cause a substantial burden in morbidity and mortality, which has motivated research and technological innovation over the past 2 decades. Surgery, radiotherapy, and systemic therapies have each played a role in management, with the greatest changes associated with the popularization of stereotactic radiosurgery. In this review, the evidence behind each modality used in the management of brain metastases for non-small-cell lung cancer patients is examined, and recommendations regarding the current standards of care and areas of future research focus are provided.

Abstract
OBJECTIVE Patients with symptomatic brain metastases secondary to mass effect are often candidates for surgery. However, many of these surgical candidates are also found to have multiple asymptomatic tumors. This study aimed to determine the outcome of surgical resection of symptomatic brain metastases followed by chemotherapy or radiotherapy (RT) for the remnant asymptomatic lesions in non-small cell lung cancer (NSCLC) patients with multiple brain metastases. METHODS We conducted a retrospective review of the medical records of 51 NSCLC patients with symptomatic multiple brain metastases who underwent surgical resection, of whom 38 had one or more unresected asymptomatic lesions subsequently treated with chemotherapy and/or RT. Thirteen patients underwent resection of all metastatic lesions. RESULTS Median survival for overall patient population after surgical resection was 10.8 months. Median survival for patients with surgical resection of all brain metastases was not significantly different with patients who underwent surgical resection of only symptomatic lesions (6.5 months vs. 10.8 months; p=0.97). There was no statistically significant difference in survival according to the number of tumors (p=0.86, 0.16), or post-surgical treatment modalities (p=0.69). CONCLUSION The survival time of NSCLC patients with multiple brain metastases after surgery for only symptomatic brain metastases is similar to that of patients who underwent surgery for all brain metastases. The remaining asymptomatic lesions may be treated with chemotherapy or radiotherapy. The optimal treatment modality, however, needs to be defined in prospective trials with larger patient cohort.

Abstract
Brain metastases are frequently encountered in patients with non-small-cell lung cancer (NSCLC) and are a significant cause of morbidity and mortality. Chemotherapy has been deemed ineffective under the hypothesis that the blood-brain barrier (BBB) limits the delivery of chemotherapeutic agents to the brain. Thus, radiotherapy and occasionally surgery have been selected for the treatment of brain metastases. However, recent clinical data suggested that chemotherapy may be an effective treatment option for patients with brain metastases, since patients who have developed brain metastases may have an inherently compromised BBB. The prognosis of NSCLC patients with brain metastases is generally poor and more effective treatment is required to improve their prognosis. Bevacizumab (Avastin) is a humanized monoclonal antibody that inhibits tumor angiogenesis by neutralizing the vascular endothelial growth factor. Preclinical data indicated that bevacizumab may be effective in preventing as well as treating preexisting brain metastases. Although safety concerns regarding intracranial hemorrhage have been a barrier for the use of bevacizumab in patients with brain metastases, safety data have gradually been accumulated through recent clinical trials. In this review, we aimed to summarize the currently available treatment options and present a therapeutic strategy for NSCLC patients with brain metastases, with a special emphasis on bevacizumab.
