Prothrombin and its active derivative thrombin are key members of the coagulation system. The only site of extra-hepatic thrombin expression is the central nervous system (CNS), where it is involved in brain development, protection, and regeneration. Thrombin affects various degenerative and ischemic CNS diseases like Alzheimer's, multiple sclerosis, cerebral ischemia, and hemorrhage in a dose dependent manner. Additionally, the association of thrombin with various malignancies has recently become evident. Thrombin facilitates the interaction between tumor cells with platelets, endothelial cells, and the adhesion to matrix proteins in various tumor types...

Medulloblastoma is a WHO grade IV neoplasm that is usually restricted to the central nervous system, with metastasis occurring along the neuraxis through the ventricular system and cerebrospinal fluid. Extraneural metastasis is rare, usually occurs in bones/lymph nodes, and carries poor prognosis. We report multimodal imaging in a 14-year-old boy with desmoplastic medulloblastoma having multiple extraneural nodal and skeletal metastases, which was misdiagnosed as lymphoma. This case highlights the importance of understanding tumor biology with active clinical and radiological surveillance that is useful in early detection of extraneural metastasis of this aggressive tumor that helps in advocating appropriate and timely treatment...

Patients with epidermal growth factor receptor (EGFR)-positive (EGFR(+)) non-small-cell lung cancer (NSCLC) show improved response rates when treated with tyrosine kinase inhibitors (TKIs) such as erlotinib. However, standard daily dosing of erlotinib often does not reach therapeutic concentrations within the cerebrospinal fluid (CSF), resulting in progression of central nervous system (CNS) disease. Intermittent, high-dose administration of erlotinib reaches therapeutic concentrations within the CSF and is well tolerated in patients...

The cancer relapses of endometrial carcinoma are most frequently localized in the vaginal cuff, pelvic and para-aortic lymph nodes, peritoneum, and lungs, whereas the abdominal wall, intra-abdominal organs, and central nervous system are unusual sites. We present F-FDG PET/CT appearance of a pathologically proven abdominal wall metastasis in a 51-year-old woman with a diagnosis of endometrial adenocarcinoma 4 years ago.

Meningiomas represent the most common tumours of the central nervous system in adults. Risk factors include ionizing radiation, female hormones exposure, head trauma, cell phone use, breast cancer and family history of meningioma. Despite complete surgical resection, natural history of meningiomas often includes local recurrence but very few metastatic meningiomas have been reported. Here, we report the case of a metastatic meningioma. A 43-year-old woman was firstly treated for a symptomatic parietal meningioma WHO grade II by surgical resection followed by an irradiation of the surgical bed...

In patients with non-small-cell lung cancer harboring an epithelial growth factor receptor (EGFR) active mutation, central nervous system progression after a response to EGFR tyrosine kinase inhibitors is frequent. Central nervous system metastasis, especially leptomeningeal carcinomatosis (LMC), is a serious complication and no standard treatment has been established for LMC. Here, we report two cases in which the addition of bevacizumab to erlotinib enhanced the efficacy against LMC; as a result, radiographic abnormalities decreased markedly and symptoms were well controlled...

Eph receptors are a subfamily of receptor tyrosine kinases. Eph receptor-mediated forward and ephrin ligand-mediated reverse signalings are termed bidirectional signaling. Increasing evidence shows that Eph/ephrin signaling regulates cell migration, adhesion, morphological changes, differentiation, proliferation and survival through cell-cell communication. Some recent studies have started to implicate Eph/ephrin signaling in tumorigenesis, metastasis, and angiogenesis. Previous studies have shown that EphB1 receptor and its ephrin ligands are expressed in the central nervous system...

The incidence of brain metastases of solid tumors is increasing. Local treatment of brain metastases is generally straightforward: cranial radiotherapy (e.g., whole-brain radiotherapy or stereotactic radiosurgery) or resection when feasible. However, treatment becomes more complex when brain metastases occur while other metastases, outside of the central nervous system, are being controlled with systemic therapy (chemotherapeutics, molecular targeted agents, or monoclonal antibodies). It is known that some anticancer agents can increase the risk for neurotoxicity when used concurrently with radiotherapy...

Afatinib, a second-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, has been approved worldwide as a first-line treatment for advanced non-small cell lung cancer (NSCLC) that harbors activating EGFR mutations. Here, we have reviewed the recent clinical developments in the treatment of lung cancer using afatinib. Emerging data have revealed the overall survival benefit of first-line afatinib therapy in patients with advanced EGFR (del19)-positive NSCLC. Phase III studies of afatinib have shown the effectiveness of afatinib as a second-line treatment for advanced lung squamous cell carcinoma, as well as the benefit of continuing afatinib therapy in combination with cytotoxic chemotherapy for advanced NSCLC after the occurrence of disease progression in patients who are receiving afatinib monotherapy...

INTRODUCTION: Non-small cell lung cancer presents at an advanced stage at diagnosis in two-thirds of cases. The most frequent metastatic sites are the central nervous system, adrenal glands and bones. By contrast, the thyroid gland is an extremely rare site of dissemination. CASE DESCRIPTION: A 64-year-old Caucasian man previously treated with radiosurgery and brain metastasectomy followed by right middle lobectomy for a squamous cell lung carcinoma had a metachronous solitary metastasis to the thyroid gland, as confirmed by fine-needle aspiration cytology and open biopsy...

Most cancer deaths are due to metastasis, and epithelial-to-mesenchymal transition (EMT) plays a central role in driving cancer cell metastasis. EMT is induced by different stimuli, leading to different signaling patterns and therapeutic responses. Transforming growth factor beta (TGFbeta) is one of the best-studied drivers of EMT, and many drugs are available to target this signalling pathway. A comprehensive bioinformatics approach was employed to derive a signature for TGFbeta-induced EMT which can be used to score TGFbeta-driven EMT in cells and clinical specimens...

BACKGROUND: Patients with EGFR-mutant lung cancers treated with EGFR tyrosine kinase inhibitors (TKIs) develop clinical resistance, most commonly with acquisition of EGFR T790M. Evolutionary modeling suggests that a schedule of twice weekly pulse and daily low-dose erlotinib may delay emergence of EGFR T790M. Pulse dose erlotinib has superior central nervous system (CNS) penetration and may result in superior CNS disease control. METHODS: We evaluated toxicity, pharmacokinetics, and efficacy of twice weekly pulse and daily low-dose erlotinib...

Brain metastasis is an inauspicious consequence of lung cancer. However, the majority of cancer cells that seep into the brain died of unknown causes, only a few survived and developed into metastatic brain tumor. Communication between cancer cells and host tissue is viewed as an essential event during metastasis, but little is known about the accurate control of this processes. Within the lesion of brain metastasis, abundant activated astrocytes are observed with lung cancer cells. Previous studies have demonstrated that the astrocyte network served a protective role in the central nervous system (CNS) and most malignant cells that seep into the brain perish were rejected by astrocytes...

Cisplatin and paclitaxel both can cause peripheral neurotoxicity as an adverse effect; however, central nervous system neurotoxicity in the form of seizures is rare. We report a case of a 36-year-old female patient of metastatic carcinoma cervix, who developed seizure shortly after cisplatin infusion. Her laboratory investigations were within normal limits. Computed tomography scan and magnetic resonance imaging of the brain did not reveal brain primary metastasis or meningeal carcinomatosis. She had no complaints of fever, no signs and symptoms of infection, and no history of seizure nor was she on any medication predisposing to such an event...

Bertram Richter, Lakshmi Harinath, Cunfeng Pu, Kristen Stabingas
Metastatic spread of a systemic neoplasm to a central nervous system malignancy is a rare but well-documented phenomenon. Over 100 case reports of tumor-to-tumor spread involving the central nervous system have been described since the first report in 1930. Overwhelmingly, intracranial meningioma represents the most common recipient tumor, while breast and lung are the first and second most common donor malignancies, respectively. The propensity for meningiomas to harbor metastatic lesions has been attributed to cell-to-cell adhesion molecules, favorable metabolic environment as well as hormonal and mechanical factors...

BACKGROUND: Solitary fibrous tumors (SFTs) are rare mesenchymal tumors that occasionally occur in the central nervous system (CNS). It is difficult to fully understand their clinical characteristics, partly due to a limited number of reported cases. METHODS: We reviewed 24 patients admitted to our institution between 2009 and 2016 with CNS solitary fibrous tumors. We reviewed and analyzed patient profiles, such as demographics, presentations, imaging studies, extent of resection, and adjuvant treatment...

The metastasis of cancer to the central nervous system (CNS) remains a devastating clinical reality, carrying an estimated survival time of less than one year in spite of recent therapeutic breakthroughs for other disease contexts. Advances in brain metastasis research are hindered by a number of factors, including its complicated nature and the difficulty of modeling metastatic cancer growth in the unique brain microenvironment. In this review, we will discuss the clinical challenge, and compare the merits and limitations of the available models for brain metastasis research...
