Li S, Xu S, Li L, Xue Z, He L. Efficacy and safety of EGFR-TKI combined with WBRT vs. WBRT alone in the treatment of brain metastases from NSCLC: a systematic review and meta-analysis. Front Neurol 2024; 15:1362061. [PMID: 38737351 PMCID: PMC11085739 DOI: 10.3389/fneur.2024.1362061] [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: 12/27/2023] [Accepted: 04/04/2024] [Indexed: 05/14/2024] Open
Abstract
Background The efficacy and safety of combining epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) with whole-brain radiotherapy (WBRT) for treating brain metastases in non-small cell lung cancer patients remains to be determined. Methods A systematic search was conducted using databases including PubMed, Embase, Web of Science, Cochrane, Wanfang, and China National Knowledge Infrastructure (CNKI), aiming to identify relevant clinical studies on the treatment of brain metastases originating from non-small cell lung cancer through the combination of EGFR-TKI and WBRT. Statistical analysis was performed utilizing Stata 17.0 software, covering clinical studies published until March 1, 2023. Results This analysis incorporated 23 randomized controlled trials (RCTs), involving a total of 2,025 patients. Of these, 1,011 were allocated to the group receiving both EGFR-TKI and WBRT, while 1,014 were assigned to the WBRT alone group. The findings reveal that the combination of EGFR-TKI and WBRT significantly improves the intracranial objective remission rate (RR = 1.57, 95% CI: 1.42-1.74, p < 0.001), increases the intracranial disease control rate (RR = 1.30, 95% CI: 1.23-1.37, p < 0.001), and enhances the 1-year survival rate (RR = 1.48, 95% CI: 1.26-1.73, p < 0.001). Additionally, this combined treatment was associated with a significant survival advantage (RR = 1.48, 95% CI: 1.26-1.73, p < 0.001) and a reduced incidence of adverse effects (RR = 0.65, 95% CI: 0.51-0.83, p < 0.001), particularly with respect to nausea and vomiting (RR = 0.54, 95% CI: 0.37-0.81, p = 0.002) and myelosuppression (RR = 0.59, 95% CI: 0.40-0.87, p = 0.008). However, no statistically significant differences were observed for diarrhea (RR = 1.15, 95% CI: 0.82-1.62, p = 0.418), and skin rash (RR = 1.35, 95% CI: 0.88-2.07, p = 0.164). Conclusion In contrast to WBRT alone, the combination of EGFR-TKI and WBRT significantly improves intracranial response, enhancing the objective response rate, disease control rate, and 1-year survival rate in NSCLC patients with brain metastases. Moreover, aside from mild cases of rash and diarrhea, there is no statistically significant increase in the incidence of additional adverse effects. Based on the comprehensive evidence collected, the use of third-generation EGFR-TKI combined with WBRT is recommended as the preferred treatment for NSCLC patients with brain metastases, offering superior management of metastatic brain lesions.

Validation of the Lung-Mol Graded Prognostic Assessment (GPA) System for the Prognosis of Patients Receiving Radiotherapy for Brain Metastasis From Non-small Cell Lung Cancer. Cureus 2024; 16:e57485. [PMID: 38707125 PMCID: PMC11066373 DOI: 10.7759/cureus.57485] [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] [Accepted: 04/02/2024] [Indexed: 05/07/2024] Open
Abstract
PURPOSE The Lung-mol graded prognostic assessment (GPA) system predicts the prognosis of patients with brain metastases (BM) from non-small cell lung cancer (NSCLC) separately for adenocarcinoma and non-adenocarcinoma. This study aimed to validate the Lung-molGPA system using a cohort of patients in our institution who received radiotherapy for BM. MATERIALS AND METHODS Three hundred and thirty-nine patients with NSCLC who received their first course of radiotherapy for BM were included in the analysis. Among them, 65 received their second course of radiotherapy for BM. Data on sex, age, Karnofsky performance status (KPS), extracranial metastases (ECM), number of BM, histological type, and gene mutations were collected according to the Lung-molGPA system. We examined the validity of the scores assigned to the factors included in the Lung-molGPA system, separately for adenocarcinoma and non-adenocarcinoma. In addition, we validated the Lung-molGPA system to predict survival during both the first and second courses of radiotherapy. RESULTS The factors in the Lung-molGPA were significantly associated with survival, except for age in non-adenocarcinoma with marginal significance. Regarding discrimination ability, the C-indices were 0.65 and 0.69 for adenocarcinoma and non-adenocarcinoma, respectively, in the first course of radiotherapy for BM, while those in the second course were 0.62 and 0.74, respectively. Survival prediction by Lung-molGPA was almost consistent with actual survival in the first course of radiotherapy, except for the score of 0-1.0 in both histologies and 2.5-3.0 in non-adenocarcinoma. In the second course of radiotherapy, median survival could be predicted for some patients with adenocarcinoma. CONCLUSIONS Our study confirms the validity of Lung-molGPA for the estimation of median survival based on patient characteristics at the time of initiation of radiotherapy for patients in the first course of radiotherapy and shows that it may be applicable to patients with adenocarcinoma in the second course of radiotherapy.

Abstract
Non-small cell lung cancer (NSCLC) is the most common cause of brain metastasis (BM). Little is known about immune checkpoint inhibitor activity in the central nervous system, especially in patients receiving monotherapy for tumors with a tumor proportion score (TPS) ≥ 50%. This noninterventional, retrospective, multicenter study, conducted with the GFPC, included treatment-naïve patients strongly positive for PD-L1 (TPS ≥ 50%) with BM receiving first-line single-agent pembrolizumab treatment between May 2017 and November 2019. The primary endpoints were centrally reviewed intracranial overall response rates (ORRs), centrally reviewed intracranial progression-free survival (cPFS), extracranial PFS, and overall survival were secondary endpoints. Forty-three patients from five centers were included. Surgical or local radiation therapy was administered to 31 (72%) patients, mostly before initiating ICI therapy (25/31). Among 38/43 (88.4%) evaluable patients, the intracranial ORR was 73%. The median PFS was 8.3 months. The cerebral and extracerebral median PFS times were 9.2 and 5.3 months, respectively. The median OS was 25.5 months. According to multivariate analysis, BM surgery before ICI therapy was the only factor significantly associated with both improved PFS (HR = 0.44) and OS (HR = 0.45). This study revealed the feasibility and outcome of front-line pembrolizumab treatment in this population with BM.

Abstract
OBJECTIVE The optimal primary site treatment modality for non-small cell lung cancer with brain oligometastases is not well established. This study sought to evaluate the long-term survival of patients with non-small cell lung cancer with isolated brain metastases undergoing multimodal therapy with or without thoracic surgery. METHODS Patients with cT1-3, N0-1, M1b-c non-small cell lung cancer with synchronous limited metastatic disease involving only the brain treated with brain stereotactic radiosurgery or neurosurgical resection in the National Cancer Database (2010-2017) were included. Long-term overall survival of patients who underwent multimodal therapy including thoracic surgery ("Thoracic Surgery") versus systemic therapy with or without radiation to the lung ("No Thoracic Surgery") was evaluated using Kaplan-Meier analysis, Cox proportional hazards modeling, and propensity score matching. RESULTS Of the 1240 patients with non-small cell lung cancer with brain-only metastases who received brain stereotactic radiosurgery or neurosurgery and met study inclusion criteria, 270 (21.8%) received primary site resection. The Thoracic Surgery group had improved overall survival compared with the No Thoracic Surgery group in Kaplan-Meier analysis (P < .001) and after multivariable-adjusted Cox proportional hazards modeling (P < .001). In a propensity score-matched analysis of 175 patients each in the Thoracic Surgery and No Thoracic Surgery groups, matching on 13 common prognostic variables, thoracic surgery was associated with better survival (P = .012). CONCLUSIONS In this national analysis, patients with cT1-3, N0-1, M1b-c non-small cell lung cancer with isolated limited brain metastases had better overall survival after multimodal therapy including thoracic surgery compared with systemic therapy without surgery. Multimodal thoracic treatment including surgery can be considered for carefully selected patients with non-small cell lung cancer and limited brain metastases.

Abstract
Brain metastases are especially common in anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC), with a cumulative incidence of over 50% and associated with a poor prognosis, high symptom burden, and decreased quality of life. Lorlatinib is a brain-penetrant, third-generation ALK tyrosine kinase inhibitor (TKI), which has a high potency against resistance mutations seen with earlier generation ALK TKIs. In 2018, lorlatinib was granted accelerated approval in second- and third-line treatment for use in patients with ALK-positive metastatic NSCLC on the basis of phase 1/2 study results. This initial approval was expanded for first-line treatment of patients with ALK-positive metastatic NSCLC on the basis of the interim analysis of the phase 3 CROWN study showing longer progression-free survival, time to intracranial progression, duration of response, and objective response rate compared with crizotinib. This manuscript is a transcript of our podcast, in which we discuss the clinical significance of controlling the onset of brain metastases, considerations in selecting a first-line therapy option, efficacy and safety observed in patients with and without brain metastases, and rationales for using lorlatinib upfront versus reserving for a later line in therapy.

Eur J Pharmacol 2023; 945:175571. [PMID: 36804545 DOI: 10.1016/j.ejphar.2023.175571] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 02/02/2023] [Accepted: 02/02/2023] [Indexed: 02/19/2023]
Abstract
Aumolertinib is an irreversible third-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), although it has been administered for the treatment of epidermal growth factor receptor (EGFR) mutant non-small cell lung cancer (NSCLC). However, it is unclear whether aumolertinib combined with ionizing radiation (IR) has potential therapeutic effects in treating brain metastases (BM) tumors from NSCLC. This study explored the anti-tumor effects of aumolertinib combined with IR in epidermal growth factor receptor mutated (EGFRm) NSCLC BM tumors. First, we established a xenograft model of NSCLC BM tumors in BALB/c nude mice and assessed the anti-tumor effects of this combination. Furthermore, we examined the concentrations of aumolertinib in brain tissue and blood using liquid chromatography-mass spectrometry (LC-MS); after that, we used CCK-8, colony formation, flow cytometry assay, and immunofluorescence staining to detect the effects of aumolertinib combined with IR upon PC-9 and NCI-H1975 cells, such as cell proliferation, survival, apoptosis, cycle distribution, the situation of DNA damage, and the expression levels of relevant proteins which were detected via western blotting; finally, we chose a clinical case with which to explore the clinical benefits to the EGFRm NSCLC BM patient after the treatment of the aforementioned combination. The experiments of NSCLC BM tumor animal models demonstrated that the combination enhanced the therapeutic effects and increased the intracranial accumulation of aumolertinib; the combination can inhibit cell proliferation and survival, delay the repair of DNA damage, and increase the rates of cell apoptosis and aumolertinib abrogated G2/M phase arrest, which the IR induced; the clinical study verified that the combination demonstrated better patient benefits. In conclusion, our study demonstrated that combining aumolertinib and IR has promising anti-tumor effects in EGFR-mutant NSCLC and that this combined treatment modality may be employed as a potential therapeutic strategy for EGFR-mutant NSCLC BM patients clinically.

Abstract
Lung cancer is a disease associated with significant morbidity and mortality on a global setting. This form of cancer commonly gives raise to metastatic lesions the brain, which can further worsen outcomes. In this focused review, we discuss an overview of lung cancers that metastasize to the brain: known risk factors; means of detection and diagnosis; and options for treatment including a comparison between surgical resection, stereotactic radiosurgery, and whole-brain radiation therapy. These interventions are still being assessed by clinical trials and continue to be modified through evidence-based practice.

Abstract
Purpose. To observe the remission rate and side effects of immunotherapy combined with radiotherapy in patients with brain metastasis of driver gene-negative non-small-cell lung cancer (NSCLC). Methods. 152 patients with NSCLC brain metastasis admitted to our hospital from January 2019 to December 2021 were selected as the research objects. Patients were divided into a single group (85 cases) and a combined group (67 cases) according to treatment methods. The therapeutic effects and side effects of the single group and combined group were compared. In addition, the patients who received immunotherapy combined with radiotherapy were divided into three subgroups: A, B, and C, and the therapeutic effects and side effects of different radiotherapy modes were compared among group A [whole brain radiotherapy (WBRT)], group B (WBRT combined with local radiotherapy) and group C (local radiotherapy). Results. The objective response rate (ORR) and disease control rate (DCR) in the combined group were higher than those in the single group (
). The incidence of reactive capillary hyperplasia and immune-related pneumonia in the combined group were higher than that in the single group (
). There was no significant difference in the incidence of other side effects between the two groups (
). ORR and DCR in group B were higher than those in group A (
). There was no significant difference in the incidence of side effects among the three groups (
). Conclusion. Immunotherapy combined with radiotherapy is effective in patients with brain metastasis of driver gene-negative NSCLC, which can improve the disease control rate without increasing the side effects. In addition, WBRT combined with local push radiotherapy is effective and safe. Clinical Study Registration Number. The Clinical study registration number is K2019086.
