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...
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 ...
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.
Brain metastasis is a common complication of advanced malignancies, especially, lung cancer, breast cancer, renal cell carcinoma, and melanoma. Traditionally surgery, when indicated, and radiation therapy, either as whole-brain radiation therapy or stereotactic radiosurgery, constituted the major treatment options for brain metastases. Until recently, most of the systemic chemotherapy agents had limited activity for brain metastases. However, with the advent of small molecule tyrosine kinase inhibitors and ...
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.
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.
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...
Metastases from prostate cancer to the brain are very unusual and very few case series have been reported in the literature. Present study was performed to assess the proportion of brain metastasis from prostate cancer among other brain metastasis in men, to evaluate the distribution, pattern and magnetic resonance imaging (MRI) appearance of these metastatic lesions, and prognosis of brain metastasis in patients with prostate 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...
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; ClinicalTrials.gov identifier: NCT01449461) and in the subsequent ...
Until 50% of patients with renal cancer or melanoma, develop brain metastases during the course of their disease. Stereotactic radiotherapy has become a standard of care for patients with a limited number of brain metastases. Given the radioresistant nature of melanoma and renal cancer, optimization of the fractionation of stereotactic radiotherapy is needed. The purpose of this retrospective study was to elucidate if hypofractionated stereotactic radiotherapy (HFSRT) impacts local control of brain metastas...
To summarize current approaches in the management of brain metastases from non-small cell lung cancer (NSCLC).
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...
According to lung cancer guidelines, positron emission tomography scan is recommended for initial evaluation of bone metastasis. However, guidelines differ in their recommendations for when it should be used. We investigated the appropriate use of bone imaging in nonsmall cell lung cancer (NSCLC) patients. One hundred seventy-seven consecutive NSCLC patients who had distant metastases at presentation and were admitted between January 2012 and April 2016 were retrospectively reviewed. Among patients with bon...
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...
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...
Treatment for advanced lung adenocarcinoma (AC) has become increasingly personalized based on molecular results. However, for patients with AC brain metastases (BMs), intracranial outcomes based on molecular subtype and the frequency of molecular aberrations are less well defined. This study sought to report targeted next-generation sequencing results and investigate molecularly based outcomes for patients with AC-BMs treated with radiotherapy.
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.
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.
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.
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.
To demonstrate the usefulness of complementary next-generation sequencing (NGS) and immunohistochemistry (IHC) counting, we analyzed 196 patients with non-small cell lung cancer (NSCLC) who underwent surgical resection and adjuvant chemotherapy. Formalin-fixed paraffin-embedded samples of adenocarcinoma (ADC), squamous cell carcinoma (SqCC), and large-cell carcinoma (LCC) were used to prepare tissue microarrays and were examined by protein H-score IHC image analysis and NGS for oncogenes and proto-oncogenes...
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.
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.
We reported the results of an Italian large retrospective analysis that evaluated the effectiveness and safety of T-DM1 in 'field-practice' breast cancer patients. We performed a sub-analysis to investigate the clinical activity of T-DM1 in patients with brain metastases (BMs).
