BACKGROUND:  Metastasis from one tumor into another is known as tumor-to-tumor metastasis. We report a case of a contiguous occurrence of meningioma and brain cancer metastasis. PATIENT:  A 91-year-old woman presented with a sudden onset of weakness in her right limbs and gait disturbance. Fourteen years previously, she had a tumor that was suspected to be a meningioma in the left frontal convexity with no change for several years. One year earlier to presentation she was diagnosed with lung carcinoma in the left lower lobe...

Brain metastasis is one of the leading causes of death among cancer patients. Cancer cells migrate to various sites and harbor different niche in the body which help cancer cells in their survival. The brain is one of the safest place where cancer cells are protected from immune cells. Breast, lung, and melanoma cancer cells have high propensity to migrate towards the brain. To enter the brain, cancer cells have to cross the blood brain barrier. Survival and finding new niche in the brain are directed by several mechanisms in which different cellular players take part such as astrocytes, microglia, Schwann cells, satellite cells, oligodendrocytes, and ependymal cells...

BACKGROUND: Non-small cell lung cancer (NSCLC) with different EGFR mutation types shows distinct sensitivity to tyrosine kinase inhibitors (TKIs). This study developed a patho-clinical profile-based prediction model of TKI-sensitive EGFR mutations. METHODS: The records of 1121 Chinese patients diagnosed with NSCLC from November 2008 to October 2014 (the development set) were reviewed. Multivariate logistic regression was conducted to identify any association between potential predictors and the classic sensitive EGFR mutations (exon 19 deletion and exon 21 L858R point mutation)...

Extrahepatic bile duct cancer (EBDC) is a combined type of malignancy mainly consisting of extrahepatic cholangiocarcinoma and gallbladder cancer. Clinically, it is featured with latent symptoms and early metastasis, leading to a poor prognosis. Therefore, this cohort study aimed to depict the possible metastatic patterns of EBDC of diverse sub-types and evaluate the prognostic significance of diverse metastatic destinations with data from the clinical database. Relevant data of total 4061 confirmed EBDC patients diagnosed between 2010 and 2013 from the Surveillance, Epidemiology and End Results (SEER) database was obtained...

Immunotherapy has revolutionized the treatment of non-small cell lung cancer; however, its role in the treatment response of lung brain metastasis is unknown. Understanding immunotherapy activity in the central nervous system is important in order to avoid additional toxicity, such as that associated with the use of cerebral radiotherapy. We present two cases with clinical and radiological progression with increases in size and perilesional edema of brain lesions after treatment with a combination of ipilimumab and nivolumab...

Brain metastases are the most common intracranial tumors in adults. They usually origin from: lung, breast, renal cell, and gastrointestinal cancers, as well as melanoma. Prognosis for brain metastases is still poor and classical treatment combining surgery and radiation therapy should be strongly supported with molecular approaches. However, their successful application depends on a deep understanding of not only genetic, but also epigenetic background of the disease. That will result in earlier and more precise diagnosis, successful treatment, as well as individualized estimation of clinical outcomes and prognosis...

Breast cancer metastasis to gynaecological organs is an understudied pattern of tumour spread. We explored clinico-pathologic and molecular features of these metastases to better understand whether this pattern of dissemination is organotropic or a consequence of wider metastatic dissemination. Primary and metastatic tumours from 54 breast cancer patients with gynaecological metastases were analysed using immunohistochemistry, DNA copy number profiling and targeted sequencing of 386 cancer-related genes. The median age of primary tumour diagnosis amongst patients with gynaecological metastases was significantly younger compared to a general breast cancer population (46...

Ectopic ACTH syndrome (EAS) is a potentially fatal endocrine disease that results from a variety of neuroendocrine tumors (NETs), such as small cell lung cancer (SCLC) and bronchial typical carcinoid. Typical carcinoid is usually slow growing, not associated with plasma progastrin releasing peptide (ProGRP) elevation. Here, we report a 47-year-old female smoker with progressive typical carcinoid and plasma ProGRP elevation. Several types of Cushingoid features were found on physical examination. In addition, laboratory examination showed elevated plasma ACTH and serum cortisol levels...

During the last several years, a growing number of studies have shown that microRNAs (miRNAs) participate in cancer metastasis. Brain metastasis (BM) is a frequent complication of lung adenocarcinoma (LAD), and the incidence of locally advanced LAD with BM can be as high as 30-50%. This study was performed to identify the miRNA expression patterns of LAD with BM and to determine the biological role that miRNAs play in tumorigenesis. To this end, we conducted microarray and quantitative PCR analyses to evaluate BM-related miRNAs independently validated from a total of 155 patients with LAD...

There are no effective central nervous system (CNS) metastases prevention methods in lung cancer patients. Prophylactic cranial irradiation has a limited effectiveness and relatively high toxicity. Systemic chemotherapy is not relevant in reducing the risk of CNS in lung cancer patients. The understanding of molecular background of brain metastases in non-small cell lung cancer (NSCLC) patients could contribute to the development of personalized treatments for such patients. Areas covered: This article summarizes the latest clinical trials concerning the use of radiotherapy, chemotherapy, molecularly targeted therapies, and immunotherapy in lung cancer patients, with particular consideration of brain lung cancer metastasis prevention...

BACKGROUND/AIM: Cancer stem cells (CSCs) are associated with tumorigenesis, recurrence, and metastasis. Cell-cell communication via gap junctions (GJs) between metastatic cancer cells and astrocytes is necessary for brain metastasis. Agents targeting communication between CSCs and astrocytes are expected to suppress brain metastasis. MATERIALS AND METHODS: Using the A549 CSC, a cancer stem-like cell derived from A549, we examined the effect of AS602801, an anti-cancer stem cell agent whose safety has been confirmed in a phase 2 clinical trial, on GJ communication and connexin expression using a dye-transfer assay and immunoblot analysis, respectively...
