OBJECTIVES: 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. METHODS: A total of 385 patients with metastatic malignant melanoma treated with ICB as monotherapy between 2005 and 2017 in two tertiary referral centres were included...

Meningiomas generally present as slow-growing, expanding intracranial lesions and are the most common benign intracranial tumor in adults. Rarely, meningiomas can exhibit malignant potential and present as extracranial soft-tissue masses through extension or as primary extracranial cutaneous neoplasms. Although they are uncommonly encountered by dermatologists, it is important to include meningioma in the differential diagnosis for scalp neoplasms. We present a rare case of a 68-year-old woman with scalp metastasis of meningioma 11 years after initial resection of the primary tumor...

The brain microenvironment imposes a particularly intense selective pressure on metastasis-initiating cells, but successful metastases bypass this control through mechanisms that are poorly understood. Reactive astrocytes are key components of this microenvironment that confine brain metastasis without infiltrating the lesion. Here, we describe that brain metastatic cells induce and maintain the co-option of a pro-metastatic program driven by signal transducer and activator of transcription 3 (STAT3) in a subpopulation of reactive astrocytes surrounding metastatic lesions...

INTRODUCTION: ROS1 rearranged non-small cell lung cancer (NSCLC) is classified as a distinct molecular subset with a therapeutically target. ROS1 rearrangement is most often identified in never smokers with adenocarcinoma and EGFR and ALK wild type. Treatment with tyrosine kinase inhibitors (TKIs), which target the ROS1 kinase domain, is considered standard of care. TKIs have been shown to have a robust and durable response. However, information regarding the clinical outcomes of TKI treatment, including brain metastasis, remains limited...

Advances in chemotherapy and targeted therapies have improved survival in cancer patients with an increase of the incidence of newly diagnosed brain metastases (BMs). Intracranial metastases are symptomatic in 60-70% of patients. Magnetic resonance imaging (MRI) with gadolinium is more sensitive than computed tomography and advanced neuroimaging techniques have been increasingly used in the detection, treatment planning, and follow-up of BM. Apart from the morphological analysis, the most effective tool for characterizing BM is immunohistochemistry...

Chordoma is a rare midline malignant tumor arising from embryonic remnants of the primitive notochord. The base of the skull is the second most common site of disease after the sacrococcygeal region. Intracranial chordoma constitutes about 30-35% of chordoma cases. Metastasis from chordoma is uncommon but if occurs, it tends to spread to the lungs. Cerebrospinal fluid seeding or drop metastasis is very rare. Here we describe a case of a clival chordoma with drop metastases.

BACKGROUND AND IMPORTANCE: Sarcomas make up 1% of all cases of adult cancer, with 5-10% of those classified as undifferentiated pleomorphic sarcomas (UPS/PUS) and 0.1-4.3% primary intracranial sarcomas. Intracranial undifferentiated sarcoma is characterized by an earlier age of onset and generally poorer prognosis compared to extracranial undifferentiated sarcomas. Current therapies involve surgical excision with wide margins and radiotherapy, with minimal data available regarding the efficacy of chemotherapy...

Glioma is one of the most adult intracranial tumors worldwide. Cancer testis antigens have been confirmed as new tool for immunotherapy and prognostic biomarkers in a variety of neoplasms. NY-SAR-35 has emerged to be upregulated in diverse human carcinomas. In this study, we aimed to investigate the role of NY-SAR-35 of clinical significance in glioma and investigate whether NY-SAR-35 correlate with malignant behaviors of glioma cells, including cell proliferation, apoptosis, migration, invasion and epithelial-to-mesenchymal transition (EMT)...

Background: Ependymomas are relatively uncommon tumors that constitute about 7% of all primary intracranial neoplasms. Among these, high-grade ependymomas are locally aggressive and recur most commonly at the primary site following resection. Ependymomas are also known to be the one glial neoplasm that tends to frequently metastasize inside and outside the central nervous system (CNS) that complicates workup and management. Metastasis due to surgical manipulation is common and neurosurgeons should be well-versed in the most effective methods to remove these tumors in order to avoid such metastases...

INTRODUCTION: B lymphoblastic lymphoma (B-LBL) is a rare type of lymphoma that originates from precursor lymphocytes. B-BLB in adults with brain metastases is extremely rare as the disease mainly affects children and adults. Therefore, such a seldom-seen case can easily trigger a dispute regarding clinical diagnosis and treatment.This paper reports the case of a 22-year-old man hospitalized for a head injury that resulted from a physical altercation. Upon admission to the hospital, the patient was diagnosed with a diffuse axonal injury (DAI)...

OBJECTIVE: Meningiomas are common primary brain tumors that constitute about 13% of all intracranial tumors. Matrix metalloproteinase-9 (MMP-9) is able to degrade the extracellular matrix and basement membrane leading to cancer cell invasion and metastasis. MMPs are specifically inhibited by a family of small extracellular proteins known as the tissue inhibitors of metalloproteinases (TIMPs). The objective of this project was to evaluate serum concentration of TIMP-1 and TIMP-2 in patients with different grades of meningioma...

Background Ameloblastoma is a rare benign odontogenic tumor with a metastasis rate estimated at 2% of cases, mainly involving the lung (80%) and lymph nodes (20%). Methods We hereby present the case of a 26 year old patient with a history of locally recurrent mandibular ameloblastoma who developed a temporal intracranial ameloblastoma tumor requiring a collaborative neurosurgical and maxillo-facial radical surgical approach. Conclusion Although ameloblastomas are histologically benign, the temporal topography questions the dissemination pathophysiology of the tumor (metastasis or local extension through temporal muscle fibers), mainly relevant in cases of multiple recurrences...

Tumor-to-tumor metastasis is an uncommon phenomenon, and a metastasis from an extracranial donor tumor to an intracranial recipient tumor is extremely rare. In particular, there are only 14 cases reported in the literature that describe a tumor-to-tumor metastasis involving a glioma. We present a rare case of an 83-year-old man with an 11-year history of lentigo maligna melanoma who presented with impaired balance and cognitive slowing and was found to have rapid progression of a previously known indolent right frontal brain mass...
