Generation of a New Disease-specific Prognostic Score for Patients With Brain Metastases From Small-cell Lung Cancer Treated With Whole Brain Radiotherapy (BMS-Score) and Validation of Two Other Indices.

Patients with small-cell lung cancer (SCLC) demonstrate an exception in the treatment of brain metastases (BM), because in patients with SCLC whole brain radiotherapy (WBRT) only is the preferred treatment modality. The purpose of this study was to develop a prognostic score for patients with brain metastases from SCLC treated with WBRT.

Systemic Treatment Options for Brain Metastases from Non-Small-Cell Lung Cancer.

Brain metastases are common in patients with non-small-cell lung cancer (NSCLC). Because of associated poor prognosis and limited specific treatment options, there is a real need for the development of medical therapies and strategies for affected patients. Novel compounds for epidermal growth factor receptor-dependent and anaplastic lymphoma kinase-dependent lung cancer have demonstrated blood-brain barrier permeability and have led to important improvements in central nervous system outcomes. Studies of t...

Survival after whole brain radiotherapy for brain metastases from lung cancer and breast cancer is poor in 6325 Dutch patients treated between 2000 and 2014.

Whole brain radiotherapy (WBRT) is considered standard of care for patients with multiple brain metastases or unfit for radical treatment modalities. Recent studies raised discussion about the expected survival after WBRT. Therefore, we analysed survival after WBRT for brain metastases 'in daily practice' in a large nationwide multicentre retrospective cohort.

Brief Report: Recurrently Mutated Genes Differ between Leptomeningeal and Solid Lung Cancer Brain Metastases.

When compared to solid brain metastases from NSCLC, leptomeningeal disease (LMD) has unique growth patterns and is rapidly fatal. LMD does not undergo surgical resection, limiting the tissue available for scientific research. Here we performed whole-exome sequencing (WES) on 8 LMD samples to identify somatic mutations and compared the results with 26 solid brain metastases. We found that TAS2R31 and PDE4DIP were recurrently mutated among LMD samples, suggesting involvement in LMD progression. Together with ...

Clinical Significance of PD-L1 Expression in Brain Metastases from Non-small Cell Lung Cancer.

To investigate the association between positivity for programmed cell death-ligand 1 (PD-L1) in brain metastases (BM) and the prognosis or clinical factors in patients with non-small cell lung cancer (NSCLC).

Diversity of brain metastases screening and management in non-small cell lung cancer in Europe: Results of the European Organisation for Research and Treatment of Cancer Lung Cancer Group survey.

Brain metastases (BM) are frequent in non-small cell lung cancer (NSCLC) patients, but there is a lack of evidence-based management of this patient group. We aimed to capture a snapshot of routine BM management in Europe to identify relevant research questions for future clinical trials.

WITHDRAWN: Cranial irradiation for preventing brain metastases of small cell lung cancer in patients in complete remission.

Prophylactic cranial irradiation halves the rate of brain metastases in patients with small cell lung cancer. Individual randomized trials conducted on patients in complete remission were unable to clarify whether this treatment improves survival.

Does Repeated Surgery For Recurrent Colo-Rectal Lung Metastases Results In Improved Survival?

Lung metastases occur in 10-20% of patients with colorectal cancer (CRC). Lung metastatic pathways of CRC is poorly known and the optimal management for recurrent lung metastases remains uncertain.

Gamma Knife Stereotactic Radiosurgery for the Treatment of Brain Metastases from Primary Tumors of the Urinary Bladder.

Brain metastases from bladder cancer are rare and published outcomes data are sparse. To date, no institutions have reported a series of patients with brain metastases from bladder cancer treated with stereotactic radiosurgery (SRS). Our aim was to identify patients with brain metastases from bladder primaries treated with SRS with or without surgical resection and report the clinical outcomes.

Non-small cell lung cancer brain metastases and the immune system: From brain metastases development to treatment.

Brain metastases (BM) are diagnosed frequently in non-small cell lung cancer (NSCLC) patients. Despite the high incidence of BM (up to 40% in unselected patients), patients with untreated and/or unstable BM were excluded from pivotal immune checkpoint inhibitors (ICI) NSCLC trials. Percentage of patients with stable and treated BM in these trials ranged from 9.1 to 14.7% and ICI benefit over chemotherapy was not always demonstrated. Only small trials have been completed that demonstrated ICI efficacy in loc...

Whole-Brain Radiotherapy for Brain Metastases: Evolution or Revolution?

An estimated 20% of patients with cancer will develop brain metastases. Approximately 200,000 individuals in the United States alone receive whole-brain radiotherapy (WBRT) each year to treat brain metastases. Historically, the prognosis of patients with brain metastases has been poor; however, with new therapies, this is changing. Because patients are living longer following the diagnosis and treatment of brain metastases, there has been rising concern about treatment-related toxicities associated with WBR...

Tyrosine kinase inhibitors for brain metastases in HER2-positive breast cancer.

Approximately 30-50% of advanced HER2-positive breast cancer patients will develop central nervous system (CNS) metastases, with an annual risk of around 10%, and a half of them will die from brain progression. An increased risk of brain metastases is also seen in patients with early HER2-positive breast cancer administered curative therapy. Brain metastases in HER2-positive breast cancer patients usually constitute the first site of recurrence. The administration of anti-HER2 monoclonal antibodies, trastuz...

Exploratory Analysis of Brigatinib Activity in Patients With Anaplastic Lymphoma Kinase-Positive Non-Small-Cell Lung Cancer and Brain Metastases in Two Clinical Trials.

Purpose In patients with crizotinib-treated, anaplastic lymphoma kinase gene ( ALK)-rearranged non-small-cell lung cancer (ALK-positive NSCLC), initial disease progression often occurs in the CNS. We evaluated brigatinib, a next-generation ALK inhibitor, in patients with ALK-positive NSCLC with brain metastases. Patients and Methods Patients with ALK-positive NSCLC received brigatinib (90 to 240 mg total daily) in a phase I/II trial (phI/II; identifier: NCT01449461) and in the subsequent ...

Emerging Trends in the Management of Brain Metastases from Non-small Cell Lung Cancer.

To summarize current approaches in the management of brain metastases from non-small cell lung cancer (NSCLC).

Genetic mutations associated with lung cancer metastasis to the brain.

Approximately 90% of all cancer deaths arise from the metastatic spread of primary tumours. Of all the processes involved in carcinogenesis, local invasion and the formation of metastases are clinically the most relevant, but they are the least well understood at the molecular level. As a barrier to metastasis, cells normally undergo an apoptotic process known as 'anoikis', in circulation. The recent technological advances in the isolation and characterisation of rare circulating tumour cells (CTCs) will al...

Does Stereotactic Radiosurgery Have a Role in the Management of Patients Presenting With 4 or More Brain Metastases?

Stereotactic radiosurgery (SRS) and whole brain radiation therapy (WBRT) are effective treatments for management of brain metastases. Prospective trials comparing the 2 modalities in patients with fewer than 4 brain metastases demonstrate that overall survival (OS) is similar. Intracranial failure is more common after SRS, while WBRT is associated with neurocognitive decline. As technology has advanced, fewer technical obstacles remain for treating patients with 4 or more brain metastases with SRS, but leve...

Can anticancer chemotherapy promote the progression of brain metastases?

Brain metastases natural history from one primary tumor type might be accelerated or favored by using certain systemic chemotherapy. A great deal was described in mice and suggested in human with antiangiogenic drugs, but little is known about the metastatic progression generated by the perverse effect of anticancer drugs. A total of 413 patients who underwent treatment for brain metastasis (2013-2016) were included. The identification of all previous anticancer drugs received by patients from primary tumor...

Radiosurgery for Brain Metastases: Changing Practice Patterns and Disparities in the United States.

Background: Management of brain metastases typically includes radiotherapy (RT) with conventional fractionation and/or stereotactic radiosurgery (SRS). However, optimal indications and practice patterns for SRS remain unclear. We sought to evaluate national practice patterns for patients with metastatic disease receiving brain RT. Methods: We queried the National Cancer Data Base (NCDB) for patients diagnosed with metastatic non-small cell lung cancer, breast cancer, colorectal cancer, or melanoma from 2004...

Colorectal cancer and brain metastases: An aggressive disease with a different response to treatment.

Brain metastases (BM) are rare in colorectal cancer (CRC) and are associated with a dismal prognosis. This work aims to report the rate of BM in CRC patients treated in a single institution, along with survival and prognostic factors.

Prophylactic Cranial Irradiation for Extensive Small-Cell Lung Cancer.

Small-cell lung cancer (SCLC) has a high predilection for metastasizing to the brain after chemotherapy. This has been blamed on the blood-brain barrier, which prevents chemotherapy from penetrating into the brain, thus creating a sanctuary site. It has been estimated that up to three quarters of patients with SCLC will eventually develop brain metastases. This led investigators to administer prophylactic cranial irradiation (PCI) to decrease this risk. Several trials were performed in patients with SCLC af...

A Score to Identify Patients with Brain Metastases from Colorectal Cancer Who May Benefit from Whole-brain Radiotherapy in Addition to Stereotactic Radiosurgery/Radiotherapy.

To design a tool to predict the probability of new cerebral lesions after stereotactic radiosurgery/radiotherapy for patients with 1-3 brain metastases from colorectal cancer.

Mortality After Stereotactic Radiosurgery for Brain Metastases and Implications for Optimal Utilization: A National Cancer Database Study.

Brain metastases are associated with cancer progression and poor outcomes. The use of stereotactic radiosurgery (SRS) to treat brain metastases has been increasing due to its potential to quickly treat metastatic disease while avoiding the morbidity associated with surgery or whole brain radiation therapy (WBRT). This study seeks to analyze practice patterns of the use of SRS for brain metastases, focusing on the endpoint of short-term mortality.

Patterns of disease control and survival in patients with melanoma brain metastases undergoing immune-checkpoint blockade.

Immune-checkpoint blockers (ICBs) significantly prolong overall survival (OS) in patients with advanced melanoma. Limited data are available on the efficacy and clinical benefit in patients with melanoma brain metastases (MBMs). The aim of this study was to determine whether ICB is active in an unselected cohort treated of patients with known brain metastases and if disease control correlates with the survival.

Surgery for brain metastases: An analysis of outcomes and factors affecting survival.

For patients who develop brain metastases from solid tumors, age, KPS, primary tumor status and presence of extracranial metastases have been identified as prognostic factors. However, the factors that affect survival in patients who are deemed fit to undergo resection of brain metastases have not been clearly elucidated hitherto.

BRCA1 Mutations Associated With Increased Risk of Brain Metastases in Breast Cancer: A 1: 2 Matched-pair Analysis.

Brain metastases (BM) occur in ∼5% of breast cancer patients. BRCA1-associated cancers are often basal-like and basal-like cancers are known to have a predilection for central nervous system metastases. We performed a matched-pair analysis of breast cancer patients with and without BRCA mutations and compared the frequency of BM in both groups.
