    Abstract: Intracranial metastatic disease (IMD) is a severe complication of cancer with profound prognostic implications. Patients with IMD in the setting of limited or stable extracranial disease (IMD-SE) may represent a unique and understudied subset of patients with IMD with superior prognosis. Objective To evaluate overall survival (OS), progression-free survival (PFS), and intracranial PFS (iPFS) in patients with IMD-SE secondary to any primary cancer. Data Sources Records were identified from MEDLINE, EMBASE, CENTRAL, and gray literature sources from inception to June 21, 2021. Study Selection Studies in English reporting OS, PFS, or iPFS in patients with IMD-SE (defined as IMD and ≤2 extracranial metastatic sites) and no prior second-line chemotherapy or brain-directed therapy were selected. Data Extraction and Synthesis Author, year of publication, type of study, type of primary cancer, and outcome measures were extracted. Random-effects meta-analyses were performed to estimate effect sizes, and subgroup meta-analysis and metaregression were conducted to measure between-study differences in February 2022. Main Outcomes and Measures The primary end point was OS described as hazard ratios (HRs) and medians for comparative and single-group studies, respectively. Secondary end points were PFS and iPFS. Results Overall, 68 studies (5325 patients) were included. IMD-SE was associated with longer OS (HR, 0.52; 95% CI, 0.39-0.70) and iPFS (HR, 0.63; 95% CI, 0.52-0.76) compared with IMD in the setting of progressive extracranial disease. The weighted median OS estimate for patients with IMD-SE was 17.9 months (95% CI, 16.4-22.0 months), and for patients with IMD-PE it was 8.0 months (95% CI, 7.2-12.8 months). Pooled median OS for all patients with IMD-SE was 20.9 months (95% CI, 16.35-25.98 months); for the subgroup with breast cancer it was 20.2 months (95% CI, 10.43-38.20 months), and for non–small cell lung cancer it was 27.5 months (95% CI, 18.27-49.66 months). Between-study heterogeneity for OS and iPFS were moderate ( I 2  = 56.5%) and low ( I 2  = 0%), respectively. Conclusions and Relevance In this systematic review and meta-analysis of patients with IMD-SE, limited systemic disease was associated with improved OS and iPFS. Future prospective trials should aim to collect granular information on the extent of extracranial disease to identify drivers of mortality and optimal treatment strategies in patients with brain metastases.

    Abstract: 2022 Background: Intracranial metastatic disease (IMD) is a life-altering complication for many patients with cancer. Improvements in systemic therapies have transformed the epidemiology of IMD, with some patients presenting with IMD in the context of stable extracranial disease (IMD-SECD). Among patients with metastases in other sites with similarly stable systemic disease, surgical resection and targeted therapy can result in long-term disease control and extended overall survival (OS), yet little is known about the clinical outcomes for patients with IMD-SECD. Methods: We searched MEDLINE, EMBASE, CENTRAL, and grey literature sources up to June 21, 2021 for studies reporting brain metastasis (BrM) with controlled extracranial disease (ECD) as well as IMD-SECD secondary to any primary cancer (criteria: presence of BrM and ≤2 extracranial metastatic sites, with no prior second-line chemotherapy and second-line brain-directed therapy). In studies comparing IMD-SECD and IMD patients, hazard ratios (HR) for OS and intracranial progression-free survival (iPFS) were pooled using random-effects meta-analysis, while medians for OS were estimated from single-arm IMD-SECD studies based on distribution-free summary survival curves. Results: Of 1067 records identified, 68 studies involving 5325 patients with IMD-SECD were included. Patients with IMD-SECD had prolonged OS (HR 1.93; 95% CI, 1.44-2.59; n = 10 studies; n = 877 patients) and iPFS (HR 1.59; 95% CI 1.31-1.92; n = 4 studies; n = 673 patients) compared with IMD patients. Subgroup analysis of patients with BrM and controlled versus uncontrolled ECD found prolonged OS with controlled ECD (HR 2.46; 95% CI, 1.36-4.44; n = 4 studies; n = 135 patients). Pooled median OS for all IMD-SECD patients was 20.85 months (mo) (95% CI, 16.35-25.98; n = 27 studies; n = 2159 patients). Stratification by primary cancer type showed median OS 20.18 mo (95% CI, 10.43-38.20; n = 2 studies; n = 109 patients) and 27.46 mo (95% CI, 18.27-49.66; n = 13 studies; n = 497 patients) for patients with IMD-SECD secondary to breast cancer and non-small cell lung cancer, respectively. Conclusions: Patients with IMD-SECD demonstrate prolonged OS and iPFS compared with patients with IMD, who may have more extensive systemic disease. Our results suggest that patients with IMD-SECD may represent a distinct subpopulation of patients with IMD with a uniquely favourable prognosis. It is possible that aggressive and timely treatment may significantly prolong survival for these patients. Future prospective trials should aim to investigate the efficacy of current treatment regimens in patients with IMD-SECD to further clarify optimal treatment pathways in this unique population of patients.

    Prophylactic cranial irradiation in small cell lung cancer patients in the era of magnetic resonance imaging: A systematic review and meta-analysis.
    American Society of Clinical Oncology (ASCO) ; 2023

    Abstract: e20636 Background: Patients with small cell lung cancer (SCLC) are at a particularly high risk for the development of brain metastases. Current guidelines recommend prophylactic cranial irradiation (PCI) for these patients to prevent brain metastases and prolong overall survival (OS), although the clinical evidence for recommendations stems from an era without routine use of brain imaging. We performed a systematic review and meta-analysis of all available studies reporting on PCI for SCLC patients with minimal inclusion restrictions to assesses the efficacy of PCI in patients with limited disease (LD) and extensive disease (ED) SCLC and focus on the impact of routine brain imaging. Methods: A literature search for studies reporting on PCI in SCLC patients performed in EMBASE, MEDLINE, CENTRAL, and grey literature sources identified 4,783 studies. Random-effects meta-analyses pooled hazard ratios (HR) for overall survival (OS) between PCI and no intervention groups. Results: 208 individual studies reported on outcomes related to PCI with 175 studies assessing survival differences associated with PCI, and 87 of these being amenable to meta-analysis. The majority (n = 79) were retrospective cohort studies. PCI was associated with improved OS in all SCLC patients (HR 0.60; 95% CI 0.55-0.65; n = 87 studies; n = 50,339 patients; I 2 = 77%), as well as in cohorts exclusively consisting of LD patients (HR 0.60; 95% CI 0.54-0.66; n = 58 studies; n = 22,417 patients; I 2 = 76%) or ED patients (HR 0.63; 95% CI 0.53-0.75; n = 23 studies; n = 24,997; I 2 = 75%). Only eight studies confirmed absence of IMD at restaging using magnetic resonance imaging in all patients and found OS no longer to be in favour of PCI (HR 0.75; 95% CI 0.50-1.12; n = 1,318 patients; I 2 = 77%). Pooled OS from randomized controlled trials was not associated with PCI (HR 0.88; 95% CI 0.65-1.12; n = 5 studies; n = 925 patients; I 2 = 62.5%). Among studies not amenable to meta-analysis for OS, 4 radiographically confirmed absence of IMD, but none found OS to be in favour of PCI. Conclusions: Administration of PCI is associated with a significant OS benefit, but not when considering studies that radiographically confirmed absence of IMD at restaging or randomized controlled trials, suggesting that patient selection may be contributing to this observation.

    Abstract: 8570 Background: Patients with SCLC are at high risk for the development of IMD and, subsequently, rapid intracranial progression. SRS has supplanted WBRT as first-line treatment for IMD in most solid cancers, but WBRT remains first-line treatment for IMD in SCLC patients. Data on SRS in SCLC are limited to small retrospective studies. Methods: Studies reporting on SRS in SCLC patients with IMD were collected from EMBASE, MEDLINE, CENTRAL, and grey literature sources (n = 3,732 studies). Random-effects meta-analysis pooled hazard ratios (HR) for overall survival (OS) between SRS and WBRT ± SRS boost, as well as medians for OS in months (mo) and risk rates for intracranial local (LC) and intracranial distant control (DC) in single-arm SRS studies. Results: OS following SRS was non-inferior compared with WBRT ± SRS boost (HR 0.90; 95% confidence interval (95CI), 0.73-1.10; n = 7 studies; n = 18,130 patients), and superior compared with WBRT alone (HR 0.80; 95CI, 0.66-0.96; n = 7 studies; n = 16,961 patients). Pooled median OS from single-arm studies following SRS was 8.99 mo (95CI, 7.86-10.15; n = 14 studies; n = 1,682 patients). Pooled LC and DC estimates following SRS were 81% (95CI, 67%-99%) and 66% (95CI, 50%- 86%), respectively, at 6 mo, and 78% (95CI, 61%-98%) and 58% (95CI, 46%-75%), respectively, at 12 mo. Conclusions: This systematic review and meta-analysis provides evidence that SRS may achieve analogous survival outcomes compared with WBRT in patients with SCLC and IMD, indicating that a subset of SCLC patients may benefit from first-line SRS treatment. Prospective trials should investigate the impact of metastatic burden as well as LC and DC differences between WBRT- and SRS-treated SCLC patients.

    Abstract: 8596 Background: Patients with small cell lung cancer (SCLC) have historically been characterised by poor overall survival (OS) and high risk for intracranial metastatic disease (IMD), but large-scale real-world evidence on clinical presentation and treatment in this population is lacking. These patients traditionally receive whole brain radiation therapy (WBRT) for IMD, however, a recent systematic review has indicated that OS following stereotactic radiosurgery (SRS) may be non-inferior compared with WBRT. We aim to describe the clinical characteristics and outcomes of patients with SCLC and IMD in Ontario, Canada. Methods: We included all patients diagnosed with SCLC between April 2007 and March 2018 identified through a provincial health administrative database. Information on patient and treatment characteristics, incidence and time to IMD, and OS from time of SCLC diagnosis were collected and analyzed using R. Results: A total of 8705 patients were included. Median age was 68 years (range 18-103). Most patients presented with extensive disease (n = 5625) and were diagnosed after 2011 (n = 5768). Patients who received chemotherapy (n = 5563) had significantly longer OS than those who did not (median 10.64 vs 1.58 months (mo), hazard ratio (HR) 0.36, 95% confidence interval (CI) 0.34-0.37). 6662 patients received brain imaging at the time of primary diagnosis (CT: 5126, MRI: 1536), and 88% of patients surviving longer than 6 mo received more than one follow-up brain scan. 31% developed IMD (synchronous: 1175, asynchronous: 1511) with median intracranial progression-free survival of 5.65 mo. Median OS of patients with IMD was 9.76 mo, 29 and 1300 received SRS and WBRT as first treatment for their IMD, respectively. OS was in favour of SRS over WBRT (median 20.47 vs 8.74 mo, HR 0.57, 95% CI 0.39-0.84), which remained significant in multivariate analysis (p 〈 0.001). Conclusions: OS for patients with SCLC remains poor, and many patients present with IMD. With careful selection, patients with SCLC may benefit from SRS treatment.
