Abstract
BACKGROUND Immune checkpoint inhibitors (ICIs) are an emerging tool in the treatment of brain metastases (BMs), Stereotactic radiosurgery (SRS), traditionally used for BMs, elicits an immune brain response and can act synergistically with ICIs. We aim to investigate the efficacy of ICI administered with SRS and determine the impact of timing on BM response. METHODS A systematical search was performed to identify potential studies concerning BMs managed with SRS alone or with SRS + ICI with relative timing administration (ICI concurrent with SRS, ICI nonconcurrent with SRS, SRS before ICI, SRS after ICI). The overall survival (OS), 12-month OS, local progression-free survival (LPFS), 12-month local brain control (LBC), distant progression-free survival (DPFS), 12-month distant brain control (DBC), and adverse events (intracranial hemorrhage, radionecrosis) were analyzed using the random-effects model. RESULTS A total of 16 retrospective studies with 1356 BM patients were included. Compared to nonconcurrent therapy, concurrent therapy revealed a significantly longer OS (HR= 1.43; p = 0.008) and 12-months LBC (HR = 1.91; p = 0.04), a similar 12-months DBC (HR = 1.12; p = 0.547) and higher complication rate (R = 0.77; p = 0.346). Concurrent therapy leads to a significantly higher OS compared to ICI before SRS (HR = 2.55; p = 0.0003). CONCLUSION The combination of SRS with ICI improves patients' clinical and radiological outcomes. The effectiveness of the combination is subject to the identification of an optimal therapeutic window.

Abstract
OBJECTIVE Immune checkpoint inhibitors (ICIs) and epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are commonly used in the systemic management of non-small cell lung cancer (NSCLC) brain metastases (BMs). However, optimizing control of NSCLC BM with stereotactic radiosurgery (SRS) and various systemic therapies remains an area of investigation. METHODS Between 2016 and 2019, the authors identified 171 NSCLC BM patients with 646 BMs treated with single-fraction SRS within 3 months of receiving treatment with ICIs (n = 56; 33%), EGFR-TKI (n = 30; 18%), chemotherapy and ICIs (n = 23; 14%), or standard chemotherapy alone (n = 62; 36%). Time-to-event analysis was conducted, and outcomes included distant intracranial control (DIC), local control (LC), and overall survival from SRS. RESULTS The median follow-up from BM diagnosis was 8.9 months (range 0.3-127 months). The 12-month Kaplan-Meier DIC rates were 37%, 53%, 41%, and 21% (p = 0.047) for the ICI, EGFR-TKI, ICI and chemotherapy, and chemotherapy-alone groups, respectively. On multivariate analysis, DIC was improved with EGFR-TKI (HR 0.4, 95% CI 0.3-0.8, p = 0.005) compared with conventional chemotherapy and treatment with SRS before systemic therapy (HR 0.5, 95% CI 0.3-0.9, p = 0.03) compared with after; and LC was improved with SRS before (HR 0.4, 95% CI 0.2-0.9, p = 0.03) or concurrently (HR 0.3, 95% CI 0.1-0.6, p = 0.003) compared with after. No differences in radionecrosis were noted by timing or type of systemic therapy. CONCLUSIONS The authors' analysis showed significant differences in DIC based on receipt of systemic therapy and treatment with SRS before systemic therapy improved DIC. Prospective evaluation of the potential synergism between systemic therapy and SRS in NSCLC BM management is warranted.

Abstract
Background As one of the most common causes of death in advanced non-small cell lung cancer (NSCLC), brain metastases (BM) have attracted attention and debate about treatment options, especially for patients with negative driver genes or resistance to targeted agents. Therefore, we conducted a meta-analysis to investigate the potential benefit of different therapeutic regimens for intracranial lesions in non-targeted therapy NSCLC patients. Methods A comprehensive search was conducted in databases including PubMed, Embase, and the Cochrane Library. The primary endpoints included the intracerebral objective response rate (icORR) and intracerebral progression-free survival (iPFS) in patients with BM. Results Thirty-six studies involving 1,774 NSCLC patients with baseline BM were included in this meta-analysis. Antitumor agents plus radiotherapy (RT) showed the most significant synergistic effects; the highest pooled icORR that appeared in the combination of immune checkpoint inhibitor (ICI) and RT was 81% [95% confidence interval (CI): 16-100%], and the median iPFS was 7.04 months (95% CI: 2.54-11.55 months). The pooled icORR and median iPFS of RT plus chemotherapy were 46% (95% CI: 34-57%) and 5.7 months (95% CI: 3.90-7.50 months), respectively. The highest median iPFS in nivolumab plus ipilimumab plus chemotherapy was 13.5 months (95% CI: 8.35-18.65 months). ICI plus chemotherapy also showed potent antitumor activity in BM, with a pooled icORR of 56% (95% CI: 29-82%) and a median iPFS of 6.9 months (95% CI: 3.20-10.60 months). Notably, the subgroup analysis indicated that the pooled icORR of patients in programmed cell death-ligand 1 (PD-L1) (≥50%) who received ICI was 54% (95% CI: 30-77%), and that of patients who received first-line ICI was 69.0% (95% CI: 51-85%). Conclusions ICI-based combination treatment provides a long-term survival benefit for non-targeted therapy patients, with the most significant benefits observed in improving icORR and prolonging overall survival (OS) and iPFS. In particular, patients who received first-line treatment or who were PD-L1-positive had a more significant survival benefit from aggressive ICI-based therapies. For patients with a PD-L1-negative status, chemotherapy plus RT led to better clinical outcomes than other treatment regimens. These innovative findings could help clinicians to better select therapeutic strategies for NSCLC patients with BM.

Abstract
Brain metastases from melanoma are no longer uniformly associated with dismal outcomes. Impressive tumor tissue-based (craniotomy) translational research has consistently shown that distinct patient subgroups may have a favorable prognosis. This review provides a historical overview of the standard-of-care treatments until the early 2010s. It subsequently summarizes more recent advances in understanding the biology of melanoma brain metastases (MBMs) and treating patients with MBMs, mainly focusing upon prospective clinical trials of BRAF/MEK and PD-1/CTLA-4 inhibitors in patients with previously untreated MBMs. These additional systemic treatments have provided effective complementary treatment approaches and/or alternatives to radiation and craniotomy. The current role of radiation therapy, especially in conjunction with systemic therapies, is also discussed through the lens of various retrospective studies. The combined efficacy of systemic treatments with radiation has improved overall survival over the last 10 years and has sparked considerable research interest regarding optimal dosing and sequencing of radiation treatments with systemic treatments. Finally, the review describes ongoing clinical trials in patients with MBMs.

Abstract
OBJECTIVES Common origins for brain metastases (BMs) are melanoma, lung, breast, and renal cell cancers. BMs account for a large share of morbidity and mortality caused by these cancers. The advent of new immunotherapeutic treatments has made a revolution in the treatment of cancer patients and particularly, as a new concept, if it is combined with radiotherapy, may lead to considerably longer survival. This systematic review and meta-analysis aimed to evaluate the survival rate and toxicities of such a combination in brain metastases. METHODS To perform a systematic review of the literature until January 2021 using electronic databases such as PubMed, Cochrane Library, and Embase; the Newcastle-Ottawa Scale was used to evaluate the quality of cohort studies. For data extraction, two reviewers extracted the data blindly and independently. Hazard ratio with 95% confidence interval (CI), fixed-effect model, and inverse-variance method was calculated. The meta-analysis has been evaluated with the statistical software Stata/MP v.16 (The fastest version of Stata). RESULTS In the first step, 494 studies were selected to review the abstracts, in the second step, the full texts of 86 studies were reviewed. Finally, 28 studies were selected consisting of 1465 patients. The addition of IT to RT in the treatment of brain metastasis from melanoma and non-small-cell lung carcinoma was associated with a 39% reduction in mortality rate and has prolonged overall survival, with an acceptable toxicity profile. The addition of IT to RT compared with RT alone has a hazard ratio of 0.39(95% CI 0.34-0.44). CONCLUSIONS A combination of immuno/radiotherapy (IR) for the treatment of patients with BMs from melanoma and non-small-cell lung carcinoma has prolonged overall survival and reduced mortality rate, with acceptable toxicity. In terms of timing, RT seems to have the best effect on the result when performed before or simultaneously with immunotherapy.

Abstract
BACKGROUND AND OBJECTIVE Melanoma brain metastasis (MBM) generally portends a dismal prognosis. Simultaneous use of radiotherapy (RT) and immune checkpoint inhibitor (ICI) therapy demonstrated tremendous promise and emerged as the new standard. This meta-analysis was conducted to evaluate survival outcomes and toxicities of this combination in patients with MBM. Data analyses were performed using Comprehensive Meta-Analysis software (version 2) and IBM SPSS software (version 27). METHODS A systematic literature search of PubMed, EMBASE, and the Cochrane Library (via Wiley) was conducted using PICOS/PRISMA selection protocol and included studies to evaluate survival and safety-associated outcomes of ICI + RT for the treatment of MBM. RESULTS A total 44 studies involving 2498 patients were reviewed. The pooled effect size (ES) for overall survival (OS) to compare the ICI + RT arm and ICI alone arm (HR: 0.693 [0.526-0.913, p = .001]), and compare the ICI + RT arm and brain RT alone (HR: 0.595 [0.489-0.723, p < .001)] indicated better survival outcomes in ICI + RT versus RT alone and ICI alone arms. Comparing central nervous system toxicity in the ICI + RT arm and RT alone arm, the pooled ES Grade ≥ 3 neurologic adverse events (NAEs) risk ratio ([RR] = 1.425; 95% confidence interval [CI]: 0.485-4.183; p = .519) indicated that ICI + RT nonsignificantly increased Grade 3-4 NAEs. Comparing Grade ≥ 3 radiation necrosis in the ICI + RT arm and RT alone arm, the pooled ES RR (RR = 2.73; 95% CI: 0.59-12.59; p = .199) indicated that ICI + RT nonsignificantly increased Grade ≥ 3 radiation necrosis. CONCLUSION Concurrent administration of RT and ICI evinced favorable OS outcomes and acceptable safety profile in MBM patients. Planned prospective trials are required to demonstrate the issue.

Abstract
Objectives: The goal of this quantitative research was to evaluate the impact of various factors (e.g., scheduling or radiotherapy (RT) type) on outcomes for RT vs. RT in combination with immune checkpoint inhibitors (ICI), in the treatment of brain metastases, via a meta-analysis. Methods: Clinical studies with at least one ICI+RT treatment combination arm with brain metastasis patients were identified via a systematic literature search. Data on 1-year overall survival (OS), 1-year local control (LC) and radionecrosis rate (RNR) were extracted; for combination studies which included an RT monotherapy arm, odds ratios (OR) for the aforementioned endpoints were additionally calculated and analyzed. Mixed-effects meta-analysis models were tested to evaluate impact on outcome, for different factors such as combination treatment scheduling and the type of ICI or RT used. Results: 40 studies representing a total of 4,359 patients were identified. Higher 1-year OS was observed in ICI and RT combination vs. RT alone, with corresponding incidence rates of 59% [95% CI: 54-63%] vs. 32% [95% CI: 25-39%] (P < 0.001). Concurrent ICI and RT treatment was associated with significantly higher 1-year OS vs. sequential combinations: 68% [95% CI: 60-75%] vs. 54% [95% CI: 47-61%]. No statistically significant differences were observed in 1-year LC and RNR, when comparing combinations vs. RT monotherapies, with 1-year LC rates of 68% [95% CI: 40-90%] vs. 72% [95% CI: 63-80%] (P = 0.73) and RNR rates of 6% [95% CI: 2-13%] vs. 9% [95% CI: 5-14%] (P = 0.37). Conclusions: A comprehensive, study-level meta-analysis of brain metastasis disease treatments suggest that combinations of RT and ICI result in higher OS, yet comparable neurotoxicity profiles vs. RT alone, with a superiority of concurrent vs. sequential combination regimens. A similar meta-analysis using patient-level data from past trials, as well as future prospective randomized trials would help confirming these findings.

Abstract
Randomized controlled trials have failed to report any survival advantage for WBRT combined with SRS in the management of brain metastases, despite the enhanced local and distant control in comparison to each treatment alone. Literature review have revealed important role of primary histology of the tumor when dealing with brain metastases. NSCLC responds better to combined approach even when there was only single brain metastasis present while breast cancer has registered better survival with SRS alone probably due to better response of primary tumor to advancement in surgical and chemotherapeutic agents. Furthermore, mutation status (EGFR/ALK) in lung cancer and receptor status (ER/PR/HER2) in breast cancer also exhibit diversity in their response to radiotherapy. Radioresistant tumors like renal cell carcinoma and melanoma brain metastases have achieved better results when treated with SRS alone. Secondly, single brain metastasis may benefit from local and distant brain control achieved with combined treatment. These diverse outcomes suggest a primary histology-based analysis of the radiotherapy regimens (WBRT, SRS, or their combination) would more ideally establish the role of radiotherapy in the management of brain metastases. Molecularly targeted therapeutic and immunotherapeutic agents have revealed synergism with radiation therapy particularly SRS in treating cancer patients with brain metastases. Clinical updates in this regard have also been reviewed.

Abstract
BACKGROUND Brain metastases can be effectively treated with stereotactic radiosurgery (SRS). Immune checkpoint inhibitors are now pivotal in metastatic melanoma care, but some concerns have emerged regarding the safety of their combination with radiation therapy. METHODS We present a retrospective analysis of a cohort of patients treated by anti-PD1 and SRS as a sole modality of radiation therapy (no whole brain radiation therapy at any time) in a single institution. We included patients on anti-PD1 at the time of SRS or patients who started anti-PD1 within a maximum period of 3 months following SRS and were treated at least one year before the analysis. Clinical and serial imaging data were reviewed to determine the efficacy and the rate of adverse radiation effectss of the combination. RESULTS A total of 50 patients were included. SRS targeted 1, 2 to 3 and >3 brain metastases in 17, 16 and 17 patients, respectively. Two patients died before the first evaluation. Nine patients presented with an increase in peritumoral oedema, three with intracranial haemorrhage and one patient with both oedema and haemorrhage. Median follow-up was 38.89 months (interquartile range 24.43; 45.28). Median overall survival from SRS was 16.62 months with 1-, 2- and 3-year rates of 60%, 40% and 35%, respectively. Median brain-Progression Free Survival was 13.2 months with 1, 2 and 3-year rates of 62.1%, 49.7% and 49.7%, respectively. CONCLUSIONS This real-world cohort of patients treated with a homogeneous strategy combining upfront stereotactic radiosurgery and anti-PD1 shows remarkable survival rates and does not reveal unexpected toxicity.

Abstract
The prognosis of brain metastases (BM) is traditionally poor. BM are mainly treated by local radiotherapy, including stereotactic radiosurgery (SRS) or whole brain radiation therapy (WBRT). Recently, immunotherapy (i.e., immune checkpoint inhibitors, ICI) has demonstrated a survival advantage in multiple malignancies commonly associated with BM. Individually, radiotherapy and ICI both treat BM efficiently; hence, their combination seems logical. In this review, we summarize the existing preclinical and clinical evidence that supports the applicability of radiotherapy as a sensitizer of ICI for BM. Further, we discuss the optimal timing at which radiotherapy and ICI should be administered and review the safety of the combination therapy. Data from a few clinical studies suggest that combining SRS or WBRT with ICI simultaneously rather than consecutively potentially enhances brain abscopal-like responses and survival. However, there is a lack of conclusion about the definition of "simultaneous"; the cumulative toxic effect of the combined therapies also requires further study. Thus, ongoing and planned prospective trials are needed to further explore and validate the effect, safety, and optimal timing of the combination of immunotherapy with radiotherapy for patients with BM.

Int J Cancer 2019; 146:1479-1489. [PMID: 31583684 PMCID: PMC7004107 DOI: 10.1002/ijc.32696] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2019] [Revised: 08/30/2019] [Accepted: 09/11/2019] [Indexed: 12/19/2022]
Abstract
Patients with melanoma brain metastases (MBM) still have a very poor prognosis. Several treatment modalities have been investigated in an attempt to improve the management of MBM. This review aimed to evaluate the impact of current treatments for MBM on patient‐ and tumor‐related outcomes, and to provide treatment recommendations for this patient population. A literature search in the databases PubMed, Embase, Web of Science and Cochrane was conducted up to January 8, 2019. Original articles published since 2010 describing patient‐ and tumor‐related outcomes of adult MBM patients treated with clearly defined systemic therapy were included. Information on basic trial demographics, treatment under investigation and outcomes (overall and progression‐free survival, local and distant control and toxicity) were extracted. We identified 96 eligible articles, comprising 95 studies. A large variety of treatment options for MBM were investigated, either used alone or as combined modality therapy. Combined modality therapy was investigated in 71% of the studies and resulted in increased survival and better distant/local control than monotherapy, especially with targeted therapy or immunotherapy. However, neurotoxic side‐effects also occurred more frequently. Timing appeared to be an important determinant, with the best results when radiotherapy was given before or during systemic therapy. Improved tumor control and prolonged survival can be achieved by combining radiotherapy with immunotherapy or targeted therapy. However, more randomized controlled trials or prospective studies are warranted to generate proper evidence that can be used to change the standard of care for patients with MBM.

Abstract
Radiotherapy (RT) represents a mainstay in the treatment of brain metastases (BMs) from solid tumors. Immunotherapy (IT) has improved survival of metastatic cancer patients across many tumor types. The combination of RT and IT for the treatment of BMs has a strong rationale, but data on efficacy and safety of this combination is still limited. A systematic search of PubMed, the Cochrane Central Register of Controlled Trials, and EMBASE was conducted. 33 studies were included for a total of 1520 patients, most of them with melanoma (87%). Median pooled OS was 15.9 months (95%CI 13.9-18.1). One- and 2-year OS rates were 55.2% (95% CI 49.3-60.9) and 35.7% (95% CI 30.4-41.3), respectively. Addition of IT to RT was associated with improved OS (HR = 0.54, 95%CI 0.44-0.67; P < 0.001). For patients with BMs from solid tumors, addition of concurrent IT to brain RT is able to increase survival and provide long term control.

Abstract
Until very few years ago, the oncology community dogmatically excluded any clinical potential for immunotherapy in controlling brain metastases. Therefore, despite the significant therapeutic efficacy of monoclonal antibodies to immune check-point(s) across a wide range of tumor types, patients with brain disease were invariably excluded from clinical trials with these agents. Recent insights on the immune landscape of the central nervous system, as well as of the brain tumor microenvironment, are shedding light on the immune-biology of brain metastases.Interestingly, retrospective analyses, case series, and initial prospective clinical trials have recently investigated the role of different immune check-point inhibitors in brain metastases, reporting a significant clinical activity also in this subset of patients. These findings, and their swift translation in the daily practice, are driving fundamental changes in the clinical management of patients with brain metastases, and raise important neuroradiologic challenges. Along this line, neuro-oncology undoubtedly represents an additional area of active investigation and of growing interest to support medical oncologists in the evaluation of clinical responses of brain metastases to ICI treatment, and in the management of neurologic immune-related adverse events.Aim of this review is to summarize the most recent findings on brain metastases immunobiology, on the evolving scenario of clinical efficacy of ICI therapy in patients with brain metastases, as well as on the increasing relevance of neuroradiology in this therapeutic setting.

Abstract
PURPOSE We retrospectively evaluated the tumor regression after radiotherapy in combination with the immune checkpoint inhibitor nivolumab for metastatic melanoma. MATERIALS AND METHODS We evaluated the extracranial metastatic melanoma lesions to which concomitant radiotherapy with nivolumab was administered from June 2015 to February 2017. Tumor volume and maximum diameter were measured at the time of pre-radiotherapy and best response, and the tumor reduction rate was assessed in two ways that our hospital adopts: tumor volume and diameter. RESULTS Seven lesions in five patients were evaluated. The median time from the start of nivolumab treatment to the start of radiotherapy was 5 months (range 0-22 months). The objective response rate was 85.7% in the evaluation by tumor volume and 42.9% by maximum diameter of the tumor. The objective complete response rate was 28.6% in evaluation by tumor volume and 14.3% by maximum dia. The 1-year tumor control rate was 62.5%. The 1- and 2-year overall survival rate after nivolumab treatment were 75% and 50%, respectively. Two patients who obtained a complete response had presented with vitiligo. CONCLUSION The combination of radiotherapy and nivolumab treatment produced favorable responses. Vitiligo may be correlated with a good response to concomitant radiotherapy with nivolumab.

Abstract
The successes of checkpoint blockade immunotherapy (CBI) and BRAFV600-targeted therapy trials have generated substantial promise for revolutionizing the management of patients with advanced melanoma. However, because early clinical trials of CBIs and BRAFV600-targeted therapy either excluded or included disproportionately fewer cases of melanoma brain metastases (MBMs), the survival benefit of these novel therapies for MBM remains unknown. We, therefore, evaluated the characteristics, management, and overall survival (OS) of patients who presented with cutaneous MBMs during 2010 to 2015 using the National Cancer Database, which comprises 70% of all newly diagnosed U.S. cancers. OS was analyzed with risk-adjusted proportional hazards and compared by Kaplan-Meier techniques. We found that 2,753 (36%) of patients presenting with stage 4 melanoma had MBMs. Following the 2011 FDA approvals for CBI and BRAFV600-targeted therapy, MBM patients demonstrated a 91% relative increase in 4-year OS to 14.1% from 7.4% preapproval (P < 0.001). Postapproval, the proportion of MBM patients who received CBI rose from 10.5% in 2011 to 34.0% in 2015 (P < 0.001). Initial CBI in MBM patients displayed an improved median and 4-year OS of 12.4 months (compared with 5.2 months; P < 0.001) and 28.1% (compared with 11.1%), respectively. These benefits were pronounced in MBM patients without extracranial metastases, in which CBI demonstrated improved median and 4-year OS of 56.4 months (compared with 7.7 months; P < 0.001) and 51.5% (compared with 16.9%), respectively. Using a large national cohort composed of a "real-life" MBM treatment population, we demonstrated the dramatic OS improvements associated with novel checkpoint blockade immunotherapies.

Abstract
Purpose The objective of this study was to evaluate adverse events (AEs) in patients who received both immune checkpoint inhibitors and thoracic radiation therapy (RT). In particular, we compared the rate of toxicities of concurrent versus sequential delivery of thoracic RT and checkpoint inhibitors. Methods and Materials Patient and treatment characteristics were collected on all patients at our institution who were treated with programmed cell death protein 1 (PD-1), programmed death-ligand 1 (PD-L1), and/or cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitors and underwent thoracic RT (n = 79). Receiving both treatments within 1 month was considered concurrent (n = 35; 44%), and any treatment up to 6 months apart was considered sequential (n = 44; 56%). The primary endpoint of this study was the rate of Grade ≥2 AEs from combination therapy (immunotherapy and RT), specifically those that are relevant to thoracic RT: Pneumonitis, other pulmonary events, esophagitis, dermatitis, and fatigue. Further univariate analysis was performed to compare AE rates with clinical and therapy-related variables. Results A total of 79 patients were identified, with lung cancer (n = 45) and melanoma (n = 15) being the most common primary histology. Sixty-two (78%) patients were treated with anti-PD-1 or anti-PD-L1 antibodies, 12 (15%) with anti-CTLA-4 antibodies, and 5 (6%) received both anti-PD-1/PD-L1 and anti-CTLA-4 antibodies. The median follow-up for survivors was 5.9 months (range, 2.4-55.6 months). Grade ≥2 AEs included pneumonitis (n = 5; 6%), esophagitis (n = 6; 8%), and dermatitis (n = 8; 10%). No statistically significant correlation was found between these AEs when comparing concurrent versus sequential treatment. The only significant variable was a correlation of immunotherapy drug category with Grade ≥2 esophagitis (P = .04). Conclusions Overall, Grade ≥2 AE rates of thoracic RT and immunotherapy appeared as expected and acceptable. The lack of significant differences in AE rates with concurrent versus sequential treatment suggests that even concurrent immunotherapy and thoracic RT may be safe.

Abstract
Background Targeted therapies (TT) and immune checkpoint inhibitors (ICI) are currently modifying the landscape of metastatic cancer management and are increasingly used over the course of many cancers treatment. They allow long-term survival with controlled extra-cerebral disease, contributing to the increasing incidence of brain metastases (BMs). Radiation therapy remains the cornerstone of BMs treatment (either whole brain irradiation or stereotactic radiosurgery), and investigating the safety profile of radiation therapy combined with TT or ICI is of high interest. Discontinuing an efficient systemic therapy, when BMs irradiation is considered, might allow systemic disease progression and, on the other hand, the mechanisms of action of these two therapeutic modalities might lead to unexpected toxicities and/or greater efficacy, when combined. Patients and methods We carried out a systematic literature review focusing on the safety profile and the efficacy of BMs radiation therapy combined with targeted agents or ICI, emphasizing on the role (if any) of the sequence of combination scheme (drug given before, during, and/or after radiation therapy). Results Whereas no relevant toxicity has been noticed with most of these drugs, the concomitant use of some other drugs with brain irradiation requires caution. Conclusion Most of available studies appear to advocate for TT or ICI combination with radiation therapy, without altering the clinical safety profiles, allowing the maintenance of systemic treatments when stereotactic radiation therapy is considered. Cognitive functions, health-related quality of life and radiation necrosis risk remain to be assessed. The results of prospective studies are awaited in order to complete and validate the above discussed retrospective data.

Abstract
The exclusion of "real-world" patients from registration clinical trials of cancer immunotherapy represents a significant emerging issue. For instance, a large fraction of cancer patients develops brain metastases during the course of the disease, but results from large prospective clinical trials investigating this considerable proportion of the cancer patient population are currently lacking. To provide a useful tool for the clinician in a "real-world" setting, we have reviewed the available literature regarding the safety and efficacy of immune check-point inhibitors in patients with cancer metastatic to the brain. Overall, these data provide encouraging evidence that these therapeutic agents can induce intracranial objective responses, particularly in patients with asymptomatic and previously untreated brain metastases. Larger prospective studies are needed to confirm these initial results.

Abstract
Traditional chemotherapeutic agents non-selectively eliminate cancer cells at the expense of normal tissue; in an attempt to minimize such effects, a new class of targeted agents, immunotherapy, was introduced in the late 1950s with the discovery of interferons and the development of the first cancer vaccine. Ever since, immunotherapy evolved, exploiting different cellular mechanisms including dendritic cell therapy, monoclonal antibodies, and cytokines. Immune checkpoint inhibitors (ICPI) are the most recent subclass of this family and we herein review the basis of exploiting this new subclass of immunotherapy with radiotherapy in the context of studies evaluating their effects on human subjects and focusing on the synergism between the molecular pathways operating in the background. PubMed was searched for studies evaluating the combined use of ICPI and radiotherapy among human subjects. The majority of studies noted an increased response rate in patients receiving combined therapy with no significant increase in toxicity. Outcomes varied among the different ICPI, and treatment with combined anti-PD-1 and anti-CTLA-4 had a higher response rate compared to either modality alone. Synergistic use of ICPI and radiotherapy has the potential to improve survival, however the specifics regarding treatment plan is dependent on a myriad of factors including the genetic and molecular makeup of the tumor as well as the patient.

Abstract
INTRODUCTION Intracranial metastases are a common cause of morbidity and mortality in patients with advanced NSCLC, and are frequently managed with radiation therapy (RT). The safety of cranial RT in the setting of treatment with immune checkpoint inhibitors (ICIs) has not been established. METHODS We identified patients with advanced NSCLC with brain metastases who received cranial RT and were treated with or without programmed cell death 1/programmed death ligand 1 inhibitors between August 2013 and September 2016. RT-related adverse events (AEs) were retrospectively evaluated and analyzed according to ICI treatment status, cranial RT type, and timing of RT with respect to ICI. RESULTS Of 163 patients, 50 (31%) received ICIs, whereas 113 (69%) were ICI naive. Overall, 94 (58%), 28 (17%), and 101 (62%) patients received stereotactic radiosurgery, partial brain irradiation, and/or whole brain RT, respectively. Fifty percent of patients received more than one radiation course. We observed no significant difference in rates of all-grade AEs and grade 3 or higher AEs between the ICI-naive and ICI-treated patients across different cranial RT types (grade ≥3 AEs in 8% of ICI-naive patients versus in 9% of ICI-treated patients for stereotactic radiosurgery [p = 1.00] and in 8% of ICI-naive patients versus in 10% of ICI-treated patients for whole brain RT [p = 0.71]). Additionally, there was no difference in AE rates on the basis of timing of ICI administration with respect to RT. CONCLUSIONS Treatment with an ICI and cranial RT was not associated with a significant increase in RT-related AEs, suggesting that use of programmed cell death 1/programmed death ligand 1 inhibitors in patients receiving cranial RT may have an acceptable safety profile. Nonetheless, additional studies are needed to validate this approach.

Abstract
Stereotactic radiosurgery provides effective local control, but high recurrence rate are observed while ipilimumab have shown promising improvements in survival in the treatment of melanoma brain metastases. This meta-analysis was done to review the clinical evidence regarding the combination of stereotactic radiosurgery and ipilimumab in the treatment of brain metastases from melanoma. Comprehensive research of the electronic databases (PubMed and Cochrane Library) was carried out in April 2017. Different combination of MESH headings and words were used. Review Manager was used to analyze the outcome data of interest. According to heterogeneity, fixed effects model or random effects model was adapted. Six retrospective studies comparing stereotactic radiosurgery plus ipilimumab with stereotactic radiosurgery alone were found. Total of 411 participants were included in this meta-analysis. Of that, 128 patients had received stereotactic radiosurgery + ipilimumab, while 283 patients had received stereotactic radiosurgery only. Stereotactic radiosurgery plus ipilimumab significantly improved survival when compared to stereotactic radiosurgery alone (hazard ratio: 0.74 [95% confidence interval: 0.56-0.99, P = .04]), with no significant increase in the incidence of adverse events (odds ratio 0.57 [95% confidence interval: 0.28-1.17, P = .12]). Stereotactic radiosurgery with ipilimumab is safe and effective treatment option and can be recommended for the treatment of brain metastases in patients with melanoma.

Abstract
Magnetic resonance imaging (MRI) is the cornerstone for evaluating patients with brain masses such as primary and metastatic tumors. Important challenges in effectively detecting and diagnosing brain metastases and in accurately characterizing their subsequent response to treatment remain. These difficulties include discriminating metastases from potential mimics such as primary brain tumors and infection, detecting small metastases, and differentiating treatment response from tumor recurrence and progression. Optimal patient management could be benefited by improved and well-validated prognostic and predictive imaging markers, as well as early response markers to identify successful treatment prior to changes in tumor size. To address these fundamental needs, newer MRI techniques including diffusion and perfusion imaging, MR spectroscopy, and positron emission tomography (PET) tracers beyond traditionally used 18-fluorodeoxyglucose are the subject of extensive ongoing investigations, with several promising avenues of added value already identified. These newer techniques provide a wealth of physiologic and metabolic information that may supplement standard MR evaluation, by providing the ability to monitor and characterize cellularity, angiogenesis, perfusion, pH, hypoxia, metabolite concentrations, and other critical features of malignancy. This chapter reviews standard and advanced imaging of brain metastases provided by computed tomography, MRI, and amino acid PET, focusing on potential biomarkers that can serve as problem-solving tools in the clinical management of patients with brain metastases.

Combining radiotherapy and ipilimumab induces clinically relevant radiation-induced abscopal effects in metastatic melanoma patients: A systematic review. Clin Transl Radiat Oncol 2017; 9:5-11. [PMID: 29594244 PMCID: PMC5862682 DOI: 10.1016/j.ctro.2017.12.004] [Citation(s) in RCA: 59] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2017] [Revised: 11/21/2017] [Accepted: 12/20/2017] [Indexed: 12/21/2022] Open
Abstract
Radiotherapy plus ipilimumab increases abscopal responses in metastatic melanoma patients. Radiotherapy plus ipilimumab improves the OS in metastatic melanoma patients. Radiotherapy plus ipilimumab does not increase toxicity in metastatic melanoma patients.
Background In the last years, limited studies have described that radiotherapy could produce important distant responses in unirradiated sites, the so-called “abscopal effect”. Recent evidence suggests that radiotherapy induces antigen release from tumor, in this way activating the immune system. However, radiotherapy alone is rarely enough to induce the systemic response requested for control of the metastases. With the advent of immunotherapy, the immune checkpoint inhibitors (ICI) have demonstrated impressive efficacy in various metastatic cancers. Currently, preclinical and clinical studies have reported a significant increase of abscopal responses in patients treated with the combination of radiotherapy and ICI. The purpose of this review was summarizing the clinical studies combining radiotherapy and ipilimumab (ipi), particularly focusing on abscopal responses. Methods and Materials Databases of Medline (via Pubmed) from 2009 to June 2, 2017 were reviewed to obtain English language studies reporting clinical abscopal effect in the combination of radiotherapy with exclusive ipi in metastatic melanoma cancers. Included studies reported the abscopal effect as a primary endpoint, and as secondary endpoint included overall survival and toxicity. Results A total of 16 studies met the inclusion criteria. These studies included a total of 451 patients, and in 5/16 studies the patients were treated on research protocols and followed-up prospectively. The median reported abscopal effect and OS were 26.5% and 19 months, respectively. The median toxicity ≥ Grade 3 was 18.3% ranged from 10% to 20%. Conclusion Early clinical outcomes reports suggest that the combination of ipilimumab and RT may improve survival in metastatic melanoma patients. The abscopal responses become a clinically relevant effect of such combination and should be studied in controlled randomized trials.

Abstract
BACKGROUND Numerous studies suggest that radiation can boost antitumor immune response by stimulating release of tumor-specific antigens. However, the optimal timing between radiotherapy and immune checkpoint blockade to achieve potentially synergistic benefits is unclear. MATERIAL AND METHODS Multi-institutional retrospective analysis was conducted of ninety-nine metastatic melanoma patients from 2007 to 2014 treated with ipilimumab who later received stereotactic radiosurgery (SRS) for new brain metastases that developed after starting immunotherapy. All patients had complete blood count acquired before SRS. Primary outcomes were intracranial disease control and overall survival (OS). RESULTS The median follow-up time was 15.5months. In the MD Anderson cohort, patients who received SRS after 5.5months (n=20) of their last dose of ipilimumab had significantly worse intracranial control than patients who received SRS within 5.5months (n=51) (median 3.63 vs. 8.09months; hazard ratio [HR] 2.07, 95% confidence interval [CI] 1.03-4.16, p=0.041). OS was not different between the two arms. The improvement in intracranial control was confirmed in an independent validation cohort of 28 patients treated at Yale-New Haven Hospital. Circulating absolute lymphocyte count before SRS predicted for treatment response as those with baseline counts >1000/µL had reduced risk of intracranial recurrence compared with those with ≤1000/µL (HR 0.46, 95% CI 0.0.23-0.94, p=0.03). CONCLUSIONS In this multi-institutional study, patients who received SRS for new brain metastases within 5.5months after ipilimumab therapy had better intracranial disease control than those who received SRS later. Moreover, higher circulating lymphocyte count was associated with improved intracranial disease control.

Abstract
Radiotherapy and immune checkpoint blockade are effective treatments for melanoma. Recent preclinical studies have suggested an interaction of radiotherapy and immune checkpoint blockade. Retrospective clinical studies, as well as a small number of prospective studies, have been undertaken to explore this interaction in patients with melanoma. In this review, we present the results of clinical studies combining radiotherapy and immune checkpoint blockade and conclude that this is a promising strategy worth of further investigation.

Abstract
Brain metastases (BM) affect approximately a third of all cancer patients with systemic disease. Treatment options include surgery, whole-brain radiotherapy, or stereotactic radiosurgery (SRS) while chemotherapy has only limited activity. In cases where patients undergo resection before irradiation, intraoperative radiotherapy (IORT) to the tumor bed may be an alternative modality, which would eliminate the repopulation of residual tumor cells between surgery and postoperative radiotherapy. Accumulating evidence has shown that high single doses of ionizing radiation can be highly efficient in eliciting a broad spectrum of local, regional, and systemic tumor-directed immune reactions. Furthermore, immune checkpoint blockade (ICB) has proven effective in treating antigenic BM and, thus, combining IORT with ICB might be a promising approach. However, it is not known if a low number of residual tumor cells in the tumor bed after resection is sufficient to act as an immunizing event opening the gate for ICB therapies in the brain. Because immunological data on tumor bed irradiation after resection are lacking, a rationale for combining IORT with ICB must be based on mechanistic insight from experimental models and clinical studies on unresected tumors. The purpose of the present review is to examine the mechanisms by which large radiation doses as applied in SRS and IORT enhance antitumor immune activity. Clinical studies on IORT for brain tumors, and on combined treatment of SRS and ICB for unresected BM, are used to assess the safety, efficacy, and immunogenicity of IORT plus ICB and to suggest an optimal treatment sequence.

Abstract
Stereotactic body radiation therapy (SBRT) of local tumor would induce an abscopal effect that has been observed in several kinds of human cancers; one important mechanism may involve the improved activation of the host immune system. The immune checkpoint inhibitor can overcome immune tolerance and enhance the activation of antitumor T cells. The combined treatment of SBRT and checkpoint inhibitor may represent a new promising therapeutic approach. Herein, we reported a patient with metastatic renal cell carcinoma (RCC) treated with concurrent SBRT and anti-PD-1 antibody, pembrolizumab, by which the patient achieved an amazingly systemic complete response in only 2.2 months after starting treatment. This case report indicates that the advanced RCC may benefit from the combining treatment of local SBRT and PD-1 inhibitor and provide a useful paradigm worthy of establishing a clinical trial for patients with advanced renal cell carcinoma.

Abstract
INTRODUCTION The clinical landscape of advanced melanoma drastically changed after the introduction of both targeted therapies and immunotherapy. This rapid development in systemic therapies led to a change in the management of patients with brain metastases, with the subsequent need to re-assess the role of local therapies, in particular stereotactic radiosurgery (SRS). Areas covered: In this non-systematic review, we report on the current knowledge on the use of SRS in combination with immunotherapy and BRAF/MEK inhibitors for patients with melanoma brain metastases, as well as ongoing trials in this field. Expert commentary: It is now more common to observe patients with melanoma brain metastases with better performance status and prolonged life expectancy. A combination of targeted therapy and immunotherapy, in different sequences, has been shown to be feasible and well tolerable, on the basis of retrospective reports. Additional data from ongoing prospective trials are however needed to confirm or not these findings and better explore the efficacy of the combination.

Abstract
Glioblastoma (GBM) is a primary neuroepithelial tumor of the central nervous system, characterized by an extremely aggressive clinical phenotype. Patients with GBM have a poor prognosis and only 3–5% of them survive for more than 5 years. The current GBM treatment standards include maximal resection followed by radiotherapy with concomitant and adjuvant therapies. Despite these aggressive therapeutic regimens, the majority of patients suffer recurrence due to molecular heterogeneity of GBM. Consequently, a number of potential diagnostic, prognostic, and predictive biomarkers have been investigated. Some of them, such as IDH mutations, 1p19q deletion, MGMT promoter methylation, and EGFRvIII amplification are frequently tested in routine clinical practice. With the development of sequencing technology, detailed characterization of GBM molecular signatures has facilitated a more personalized therapeutic approach and contributed to the development of a new generation of anti-GBM therapies such as molecular inhibitors targeting growth factor receptors, vaccines, antibody-based drug conjugates, and more recently inhibitors blocking the immune checkpoints. In this article, we review the exciting progress towards elucidating the potential of current and novel GBM biomarkers and discuss their implications for clinical practice.

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
Several factors must be considered to successfully integrate immunotherapy with radiation into clinical practice. One such factor is that concepts arising from preclinical work must be tested in combination with radiation in preclinical models to better understand how combination therapy will work in patients; examples include checkpoint inhibitors, tumor growth factor-beta (TGF-β) inhibitors, and natural killer (NK) cell therapy. Also, many radiation fields and fractionation schedules typically used in radiation therapy had been standardized before the introduction of advanced techniques for radiation planning and delivery that account for changes in tumor size, location, and motion during treatment, as well as uncertainties introduced by variations in patient setup between treatment fractions. As a result, radiation therapy may involve the use of large treatment volumes, often encompassing nodal regions that may not be irradiated with more conformal techniques. Traditional forms of radiation in particular pose challenges for combination trials with immunotherapy. This chapter explores these issues in more detail and provides insights as to how radiation therapy can be optimized to combine with immunotherapy.

Abstract
Immune checkpoint blockades including monoclonal antibodies (mAbs) of cytotoxic T-lymphocyte antigen-4 (CTLA-4), programmed death-1 (PD-1), and programmed death-ligand 1 (PD-L1) have been emerged as a promising anticancer therapy. Several immune checkpoint blockades have been approved by US Food and Drug Administration (FDA), and have shown notable success in clinical trials for patients with advanced melanoma and non-small cell lung cancer. Radiotherapy is a promising combination partner of immune checkpoint blockades due to its potent pro-immune effect. This review will cover the current issue and the future perspectives for combined with radiotherapy and immune checkpoint blockades based upon the available preclinical and clinical data.

Abstract
INTRODUCTION The therapeutic landscape of metastatic melanoma drastically changed after the introduction of targeted therapies and immunotherapy, in particular immune checkpoints inhibitors (ICI). In recent years, positive effects on the immune system associated to radiotherapy (RT) were discovered, and radiation has been tested in combination with ICI in both pre-clinical and clinical studies (many of them still ongoing). We here summarize the rationale and the preliminary clinical results of this approach. MATERIALS AND METHODS In the first part of this review article, redacted with narrative non-systematic methodology, we describe the clinical results of immune checkpoints blockade in melanoma as well as the biological basis for the combination of ICI with RT; in the second part, we systematically review scientific publications reporting on the clinical results of the combination of ICI and RT for advanced melanoma. RESULTS The biological and mechanistic rationale behind the combination of ICI and radiation is well supported by several preclinical findings. Retrospective observational series and few prospective trials support the potential synergistic effect between radiation and ICI for metastatic melanoma. CONCLUSION RT may potentiate anti-melanoma activity of ICI by enhancing response on both target and non-target lesions. Several prospective trials are ongoing with the aim of further exploring this combination in the clinical setting, hopefully confirming initial observations and opening a new therapeutic window for advanced melanoma patients.

Abstract
PURPOSE To evaluate the prevalence, outcomes, and toxicities of concurrent delivery of systemic therapy with stereotactic radiosurgery (SRS) for treatment of brain metastases. METHODS AND MATERIALS We conducted a retrospective review of 193 patients treated at our institution with SRS without prior whole-brain radiation therapy (WBRT) for brain metastases between 2009 and 2014. Outcome metrics included administration of concurrent systemic therapy, myelosuppression, neurotoxicity, and survival. RESULTS One hundred ninety-three patients with a median age of 61 years underwent a total of 291 SRS treatments. Thirty-seven percent of SRS treatments were delivered concurrently with systemic therapy, of which 46% were with conventional myelosuppressive chemotherapy, and 54% with targeted and immune therapy agents. Myelosuppression was minimal after treatment with both systemic therapy and SRS, with 14% grade 3-4 toxicity for lymphopenia and 4-9% for leukopenia, neutropenia, anemia, and thrombocytopenia. Neurotoxicity was also minimal after combined therapy, with no grade 4 and <5% grade 3 toxicity, 34% dexamethasone requirement, and 4% radiation necrosis, all similar to treatments with SRS alone. Median overall survival was similar after SRS alone (14.4 months) versus SRS with systemic therapy (12.9 months). In patients with a new diagnosis of primary cancer with brain metastasis, early treatment with concurrent systemic therapy and SRS correlated with improved survival versus SRS alone (41.6 vs 21.5 months, P<.05). CONCLUSIONS Systemic therapy can be safely given concurrently with SRS for brain metastases: our results suggest minimal myelosuppression and neurotoxicity. Concurrent therapy is an attractive option for patients who have both intracranial and extracranial metastatic disease and may be particularly beneficial in patients with a new diagnosis of primary cancer with brain metastasis.

Abstract
Glioblastoma is a refractory malignancy with limited treatment options at tumor recurrence. Only a small proportion of patients survive 2 years or longer with the current standard of care. Gene expression profiling can segregate newly diagnosed patients into groups with different prognoses, and these biomarkers are being incorporated into a new generation of personalized clinical trials. Using the experience from recently completed large scale, multi-faceted, randomized glioblastoma clinical trials, a new clinical trial paradigm is being established to move promising therapies forward into the newly diagnosed treatment setting. Upcoming trials using the immune check-point inhibitors are an example of this changing paradigm and these and other immunotherapies have potential as promising new treatment modalities for newly diagnosed GB patients.

Abstract
Relapses in the brain remain a major obstacle to cure in many patients with advanced melanoma. At present, the management of melanoma brain metastases continues to rely heavily on surgical and radiotherapeutic interventions, which have become safer and more effective with modern imaging, surgery and radiation technologies. Additionally, novel targeted and immunotherapeutic agents, shown to generate meaningful intracranial response and survival benefit in patients with melanoma brain metastases when compared with historical controls, expand systemic treatment options for this subset of patients. These systemic therapies become particularly important when intracranial disease burden precludes neuro- or radio-surgery. Considerable multidisciplinary research effort is ongoing to improve outcomes for melanoma patients with brain metastases, a key challenge in the management of advanced melanoma.

Abstract
A growing body of evidence has surfaced over the past 20 years that supports the use of surgery for metastasis limited in number termed ‘oligometastases’. Local therapy for oligometastases results in long progression free survival in the absence of systemic therapy, including non-small-cell lung cancer (NSCLC). Stereotactic body radiation therapy (SBRT) allows for the delivery of anatomically precise, ablative doses of radiation therapy able to achieve local control rates of approximately 80% with minimal toxicity. In NSCLC, SBRT is emerging as an effective therapy in the management of sites resistant to targeted therapy. This review summarizes the published evidence for the use of local therapy in the management of oligometsatic cancer, with a focus on SBRT and NSCLC.

Abstract
Melanoma is an aggressive malignancy with a deplorable penchant for spreading to the brain. While focal therapies such as surgery and stereotactic radiosurgery can help provide local control, the majority of patients still develop intracranial progression. Novel therapeutic combinations to improve outcomes for melanoma brain metastases (MBM) are clearly needed. Ipilimumab, the anticytotoxic T-lymphocyte-associated antigen 4 monoclonal antibody, has been shown to improve survival in patients with metastatic melanoma, but many of these trials either excluded or had very few patients with MBM. This article will review the efficacy and limitations of ipilimumab therapy for MBM, describe the current evidence for combining ipilimumab with radiation therapy, illustrate potential mechanisms for synergy, and discuss emerging clinical trials specifically investigating this combination in MBM.
