Management of anticoagulation in patients with brain metastasis.

Venous thromboembolism (VTE) is a prevalent and serious complication among cancer patients, necessitating therapeutic anticoagulation for many individuals with brain metastases. Simultaneously, patients with brain metastases, particularly those with high-risk primary tumors, have an increased risk of intracranial hemorrhage (ICH). Managing anticoagulation in these patients presents a dual challenge: preventing thromboembolism while avoiding hemorrhagic events.

A phase II, open-label, single-arm trial of pembrolizumab for recurrent meningioma and solitary fibrous tumor.

Background: Atypical and anaplastic meningiomas account for 20% of all meningioma cases. Solitary fibrous tumor (SFT) is a type of soft tissue sarcoma with similar attributes to meningioma. For patients with refractory or recurrent disease after previous surgery or radiotherapy, there is no effective treatment.

Stem the blood flow: beneficial impact of bevacizumab on survival of subventricular zone glioblastoma patients.

Purpose: Angiogenesis is a crucial step in tumorigenesis of glioblastoma (GBM). Bevacizumab, an anti-vascular endothelial growth factor drug, is approved for second-line therapy for GBM. Glioma stem cells, presumably the cell of origin of GBM, take an active role in angiogenesis.

Central nervous system metastases in breast cancer patients with germline BRCA pathogenic variants compared to non-carriers: a matched-pair analysis.

Background: Breast cancer is a common cause for central nervous system (CNS) metastasis, resulting in a significant reduction in overall survival. Germline pathogenic variants (PVs) in BRCA1/2 are the most common genetic risk factor for breast cancer, associated with poor prognostic factors. This study sought to explore the patterns and outcome of CNS metastases in breast cancer patients with germline PVs in BRCA1/2 genes.

Converging survival trends in non-small cell lung cancer patients with and without brain metastasis receiving state-of-the-art treatment.

Introduction: Historically, patients with brain metastasis (BM) have been excluded from clinical trials investigating treatments for non-small cell lung cancer (NSCLC) due to their unfavorable prognosis. Advanced treatments have increased survival prospects for NSCLC patients with BM. This study evaluated the life expectancy of NSCLC patients with and without BM in the context of contemporary treatments.

Significant Systemic Insulin Resistance is Associated With Unique Glioblastoma Multiforme Phenotype.

Background: Some glioblastoma multiforme (GBM) are characterized by the presence of gemistocytes (GCs), a unique phenotype of reactive astrocytes. Certain GCs can be identified as neoplastic cells but these cells were also found to be associated with diabetes in non-neoplastic lesions of the central nervous system. Our aim was to find a correlation between insulin - resistance metabolic features and the presence of GCs in patients with newly diagnosed GBM.

Prevalence of pathogenic germline variants in adult-type diffuse glioma.

Background: No consensus germline testing guidelines currently exist for glioma patients, so the prevalence of germline pathogenic variants remains unknown. This study aims to determine the prevalence and type of pathogenic germline variants in adult glioma.

Methods: A retrospective review at a single institution with paired tumor/normal sequencing from August 2018-April 2022 was performed and corresponding clinical data were collected.

A phase 2 study of ibrutinib maintenance following first-line high-dose methotrexate-based chemotherapy for elderly patients with primary central nervous system lymphoma.

Background: Elderly patients account for nearly 70% of all primary central nervous system lymphoma (PCNSL) cases. They cannot tolerate aggressive treatment and have poor prognosis with a median overall survival (OS) of less than 2 years and progression-free survival (PFS) of 6-16 months. Ibrutinib penetrates the blood-brain barrier and has shown activity in PCNSL.

Reciprocal interactions between innate immune cells and astrocytes facilitate neuroinflammation and brain metastasis via lipocalin-2.

Brain metastasis still encompass very grim prognosis and therefore understanding the underlying mechanisms is an urgent need toward developing better therapeutic strategies. We uncover the intricate interactions between recruited innate immune cells and resident astrocytes in the brain metastatic niche that facilitate metastasis of melanoma and breast cancer. We show that granulocyte-derived lipocalin-2 (LCN2) induces inflammatory activation of astrocytes, leading to myeloid cell recruitment to the brain.

Interventions for the management of fatigue in adults with a primary brain tumour.

Background: Fatigue is a common and disabling symptom in people with a primary brain tumour (PBT). The effectiveness of interventions for treating clinically significant levels of fatigue in this population is unclear. This is an updated version of the original Cochrane Review published in Issue 4, 2016.

Osimertinib in advanced EGFR-mutant lung adenocarcinoma with asymptomatic brain metastases: an open-label, 3-arm, phase II pilot study.

Background: Osimertinib is selective for both epidermal growth factor receptor (EGFR)-tyrosine-kinase inhibitor (TKI) sensitizing and Thr790Met mutations. While intracranial activity of osimertinib is documented in larger trials, a prospective study focusing exclusively on patients with asymptomatic brain metastases has not been reported.

Methods: In this nonrandomized, phase II, open-label, 3-arm prospective proof-of-concept pilot study, 48 patients with metastatic EGFR-mutant lung adenocarcinoma (LUAD) received osimertinib 80 mg daily.

[RAPIDLY PROGRESSING PARAPARESIS AND LOSS OF SENSATION BELOW T10 DURING NEOADJUVANT CHEMOTHERAPY FOR BREAST CANCER].

A 35 years old woman was diagnosed with clinical stage 2, grade 3, hormone receptor positive, human epidermal growth factor receptor 2 (HER2) negative invasive ductal carcinoma, with ki-67 of 60%. She was treated with neoadjuvant chemotherapy with dose dense adriamycin and cyclophosphamide followed by paclitaxel. Six days following the third cycle of paclitaxel the patient presented with rapidly progressive weakness, proximal paresthesia and decreased sensation in both legs.

Immunogenicity of the BNT162b2 mRNA COVID-19 vaccine in patients with primary brain tumors: a prospective cohort study.

Purpose: Immunogenicity of Covid-19 vaccines may be negatively impacted by anti-cancer treatment. The management of primary brain tumors (PBTs) routinely includes temozolomide and steroids, which are immune-suppressive. We aimed to determine the rate of seropositivity in PBT patients following receipt of two doses of the BNT162b2 vaccine.

Bevacizumab for stereotactic radiosurgery-induced radiation necrosis in patients with non-small cell lung cancer treated with immune check-point inhibitors.

Background: Bevacizumab was shown to be effective in the treatment of brain radiation necrosis (RN) attributed to the use of stereotactic radiosurgery (SRS). Data on its efficacy and safety in non-small cell lung cancer (NSCLC) patients treated with immune check-point inhibitors (ICI) is lacking.

Methods: A multi-center retrospective analysis of all consecutive patients with NSCLC treated with ICI, who received bevacizumab for post-SRS RN between April 2017 and June 2020.

IDH mutation status and the development of venous thromboembolism in astrocytoma patients.

Background: Venous thromboembolism (VTE) is a very common adverse event for astrocytoma patients, but validation of proposed risk biomarkers has been elusive. We examine whether the status of the isocitrate dehydrogenase (IDH) gene is a risk factor for the development of venous thromboembolism (VTE) in astrocytoma patients.

Methods: We conducted a retrospective chart review of 282 astrocytoma patients enrolled in the PROACTIVE (Prospective Assessment of Correlative Biomarker) study at MD Anderson Cancer Center (MDACC) from 9/1/2000 until 12/31/2013.

Evaluation of Seropositivity Following BNT162b2 Messenger RNA Vaccination for SARS-CoV-2 in Patients Undergoing Treatment for Cancer.

Importance: Patients with cancer undergoing treatment are at high risk of COVID-19 following SARS-CoV-2 infection; however, their ability to produce an adequate antibody response to messenger RNA SARS-CoV-2 vaccines is unclear.

Objective: To evaluate rates of antispike (anti-S) antibody response to a BNT162b2 vaccine in patients with cancer who are undergoing systemic treatment vs healthy controls.

Design, Setting, And Participants: This prospective cohort study included 102 adult patients with solid tumors undergoing active intravenous anticancer treatment and 78 controls who received the second dose of the BNT162b2 vaccine at least 12 days before enrollment.

Gemistocytes in newly diagnosed glioblastoma multiforme: Clinical significance and practical implications in the modern era.

Background: Gemistocytes (GCs) in low grade gliomas are associated with rapid growth and worse prognosis. However, their clinical significance in glioblastomas (GBM) is a matter of debate.

Aim Of Study: To investigate the clinical significance of the presence of GCs in newly-diagnosed GBM patients in the modern era.

Taxane versus vinorelbine in combination with trastuzumab and pertuzumab for first-line treatment of metastatic HER2-positive breast cancer: a retrospective two-center study.

Background: The combination of a taxane with trastuzumab and pertuzumab is standard of care for first-line treatment of human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer. The combination of vinorelbine with trastuzumab and pertuzumab showed anti-tumor activity in a phase 2 trial.

Patients And Methods: The databases of two tertiary medical centers were retrospectively searched for patients with HER2-positive metastatic breast cancer who underwent first-line treatment in 2013-2019 with a taxane or vinorelbine in combination with trastuzumab and pertuzumab.

Height in adolescence as a risk factor for glioma subtypes: a nationwide retrospective cohort study of 2.2 million subjects.

Background: Gliomas manifest in a variety of histological phenotypes with varying aggressiveness. The etiology of glioma remains largely unknown. Taller stature in adulthood has been linked with glioma risk.

Multicentric non-enhancing lesions in glioblastoma: A retrospective study.

Glioblastoma (GBM) typically presents as a single lesion. Multicentric GBM are defined as well separated lesions on MRI (enhancing and non-enhancing). Multicentric GBM with non-enhancing lesions (MNE-GBM) are rarely described in literature.

Intracranial hemorrhage with direct oral anticoagulants in patients with brain metastases.

Direct oral anticoagulants (DOACs) are increasingly prescribed in treatment of cancer-associated thrombosis, but limited data exist regarding safety of DOACs in patients with brain metastases. We aimed to determine the incidence of intracranial hemorrhage (ICH) in patients with brain metastases receiving DOACs or low-molecular-weight heparin (LMWH) for venous thromboembolism or atrial fibrillation. An international 2-center retrospective cohort study was designed.

Attention deficit hyperactivity disorder and gastrointestinal morbidity in a large cohort of young adults.

Background: Although the association of attention deficit hyperactivity disorder (ADHD) with psychiatric disorders is well known, its association with somatic diseases is unclear. Only few studies have investigated the gastrointestinal (GI) morbidity in adult patients with ADHD.

Aim: To measure gastrointestinal comorbidity and its burden on healthcare in young adults with ADHD.
