Activated platelets promote the proliferation and metastatic potential of cancer cells. Platelet activation is largely mediated through ADP engagement of purinergic P2Y12 receptors on platelets. We examined the potential of the reversible P2Y12 inhibitor ticagrelor, an agent used clinically to prevent cardiovascular and cerebrovascular events, to reduce tumor growth and metastasis. In vitro, MCF-7, MDA-MB-468, and MDA-MB-231 human mammary carcinoma cells exhibited decreased interaction with platelets treated with ticagrelor compared to untreated platelets...

Tumors often overcome the cytotoxic effects of chemotherapy through either acquired or environment-mediated drug resistance. In addition, signals from the microenvironment obfuscate the beneficial effects of chemotherapy and may facilitate progression and metastatic dissemination. Seminal mediators in chemotherapy-induced metastasis appear to be a wide range of hematopoietic, mesenchymal and immune progenitor cells, originating from the bone marrow. The actual purpose of these cells is to orchestrate the repair response to the cytotoxic damage of chemotherapy...

Breast cancer molecular subtypes, categorized jointly by hormone receptors (HR) and human epidermal growth factor-2 (HER2), are utilized to guide systemic therapy. We hypothesized distinct patterns of de novo metastasis and overall survival by molecular subtype using a retrospective cohort of 399,772 women in the National Cancer Database diagnosed with first primary invasive breast cancer between 2010 and 2014, of whom 13,924 were diagnosed with de novo metastasis from 2010 to 2013 and had follow up data. The relationship of molecular subtype with patient and tumor characteristics, including site of de novo metastasis, were examined using Chi-squared tests...

Metastasis suppressor 1 (MTSS1) has been shown to be a metastasis suppressor in a number of cancers. However, its role in lung adenocarcinoma is largely unknown. To evaluate the significance of MTSS1 expression on lung adenocarcinoma metastatic properties, the gain or loss of MTSS1 in in vivo and in vitro experiments were employed. Using an in vivo orthotopic mouse xenograft model mimicking human disease progression, stable overexpression of MTSS1 in lung adenocarcinoma cells resulted in a significant decrease in metastatic burden...

Ductal carcinoma in situ (DCIS), invasive breast cancer (IBC) and lympho-vascular invasion (LVI) represent distinct stages in breast cancer progression with different clinical implications. Altered microRNA (miRNA) expression may play a role in mediating the progression of DCIS to IBC and LVI. The aim of this pilot study was to investigate whether differential miRNA expression could play a role in breast cancer progression. Cancer cells from DCIS, IBC and LVI were microdissected from formalin fixed paraffin embedded (FFPE) tissue of five breast cancer samples...

Radiation therapy is an effective means of achieving local control in a wide range of primary tumours, with the reduction in the size of the tumour(s) thought to mediate the observed reductions in metastatic spread in clinical trials. However, there is evidence to suggest that the complex changes induced by radiation in the tumour environment can also present metastatic risks that may counteract the long-term efficacy of the treatment. More than 25 years ago, several largely theoretical mechanisms by which radiation exposure might increase metastatic risk were postulated...

Brain metastases are the most common intracranial tumors in adults, accounting for more than 50% of all such cases. The approach to and management of brain metastases have evolved significantly in recent years due to several reasons. These include advances in neurosurgical and radiotherapeutic techniques, improved systemic therapy options offering better systemic and intracranial disease control and prolongation of survival as a result of these improvements, making side-effects of proposed therapies (e.g. neurocognitive decline from whole brain radiotherapy) an important consideration...

Worldwide, colon cancer is among the most common cancer entities. Understanding the molecular background is the key to enable accurate stage determination, which is crucial to assess optimal therapy options. The search for preoperative biomarkers is ongoing. In recent years, several studies have proposed a diagnostic and prognostic role for miRNAs in cancer. Aim of this study was to evaluate miRNA expression patterns correlating with tumor stage, especially lymph node metastasis, in primary colon carcinoma tissue...

Metabolic adaptations permit tumor cells to metastasize to and thrive in the brain. Brain metastases continue to present clinical challenges due to rising incidence and resistance to current treatments. Therefore, elucidating altered metabolic pathways in brain metastases may provide new therapeutic targets for the treatment of aggressive disease. Due to the high demand for glucose in the brain, increased glycolytic activity is favored for energy production. Primary tumors that undergo Warburg-like metabolic reprogramming become suited to growth in the brain microenvironment...

Brain metastases present a significant public health issue, affecting more than 100,000 patients per year in the U.S. and result in significant morbidity. Brain metastases can occur in a variety of clinical situations ranging from multiple brain metastases with uncontrolled systemic disease to a solitary metastasis in the setting of controlled systemic disease. Additionally, advances in genomics have broadened the opportunities for targeted treatment options and potentially more durable systemic responses. As such, the treatment of brain metastases is now more tailored and multimodal, involving systemic, radiation, and surgical therapies, often in combination...

Brain metastasis is a common complication in advanced systemic cancer, with an increasing incidence. The diagnosis of brain metastasis historically portended a dismal prognosis. The successful development of effective treatments for patients with brain metastasis is complicated by the differences among cancer subtypes, the limited understanding of the underlying pathophysiology of BM, the impact of the blood-brain barrier, and other factors. There is now renewed interest in treating this often devastating complication of cancer, and in understanding the underlying mechanisms of disease in this "sanctuary" site...

Cancers with neurologic metastasis are a burdensome affliction. As primary cancer care improves, the incidence of metastatic cancer increases as a result of prolonged survival time. Because of this, advances in the understanding of the mechanisms of metastasis are important for the development of continuing management strategies. Knowing how metastatic tumor cells engage, survive, and proliferate in the central nervous system (CNS) is an important first step in developing treatment paradigms. The neural niche is the soil of the CNS that accommodates tumor cells, is a microenvironment of cell signaling that exists between the tumor cell and the native neural cellular network...

Breast cancer undergoes collective tissue invasion and, in experimental models, can collectively metastasize. The prevalence of collective invasion and its contribution to distant metastasis in clinical disease, however, remains poorly defined. We here scored the adipose tissue invasion of primary invasive ductal carcinoma (IDC), expressing E-cadherin, and E-cadherin negative invasive lobular carcinoma (ILC) and identified predominantly collective invasion patterns (86/86 samples) in both carcinoma types. Whereas collective invasion in IDC lesions retained adherens junctions, multicellular clusters and "Indian files" in ILC, despite the absence of adherens junctions (AJ) proteins E-cadherin and β-catenin, retained CD44 at cell-cell contacts...

Cancer, currently the leading cause of death in the population aged less than 85 years, poses a significant global disease burden and is anticipated to continue to increase in incidence in both developed and developing nations. A substantial proportion of cancers are amenable to surgery, with more than 60% of patients undergoing tumour resection. Up to 80% of patients will receive anaesthesia for diagnostic, therapeutic or palliative intervention. Alarmingly, retrospective studies have implicated surgical stress in disease progression that is predominantly characterised by metastatic disease-the primary cause of cancer-associated mortality...

Portal vein embolization (PVE) can be required to stimulate liver regeneration before hepatectomy for colorectal liver metastasis (CRCLM), however PVE may also trigger CRCLM progression in patients initially exhibiting chemotherapy response. Using RNA-seq, we aimed to determine the molecular networks involved in metastatic progression in this context. A prospective study including all CRCLM patients undergoing PVE prior to hepatectomy was conducted. Paired biopsies of metastatic lesions were obtained prior to and after PVE and total RNA was isolated and used to prepare Illumina rRNA-depleted TruSeq stranded cDNA libraries for HiSeq 100 bp paired-end sequencing...

Current preclinical models of metastatic disease (particularly oligometastases) suggest that metastases appear in a hierarchical order. We attempted to identify systematic patterns of metastasis in non-small cell lung cancer (NSCLC) after radiation therapy (XRT). We analyzed 1074 patients treated from 12/21/1998 through 8/20/2012 with ≥60 Gy definitive radiation for initially non-metastatic NSCLC. Location and time of metastases were recorded. Regional nodal failure was noted, as was subsequent distal failure...

Secondary tumors of the ovary account for 10-25% of all ovarian malignancies. The most common tumors that give rise to ovarian metastases include breast, colorectal, endometrial, stomach, and appendix cancer. The correct diagnosis of secondary ovarian tumors may be challenging as they are not infrequently misdiagnosed as primary ovarian cancer, particularly in the case of mucinous adenocarcinomas. The distinction from the latter is essential, as it requires different treatment. Immunohistochemistry plays an important role in distinguishing primary ovarian tumors from extra-ovarian metastases and, furthermore, may suggest the primary tumor site...

Melanoma patients with additional positive lymph nodes in the completion lymph node dissection (CLND) following a positive sentinel lymph node (SLN) biopsy would have a poorer prognosis than patients with no additional positive lymph nodes. We hypothesize that the progression of disease from the SLN to the non-SLN compartment is orderly and is associated with the worsening of the disease status. Thus, the SLN and non-SLN compartments are biologically different in that cancer cells, in general, arrive in the SLN compartment before spreading to the non-SLN compartment...
