Environmental signals perceived by the brain abate pro-metastatic monocytes by dampening glucocorticoids receptor signaling.

While positive social-behavioral factors predict longer survival in cancer patients, the underlying mechanisms are unknown. Since tumor metastasis are the major cancer mortality factor, we investigated how an enriched environment (EE) conductive to enhanced sensory, cognitive and motor stimulation impact metastatic progression in lungs following intravasation in the circulation. We find that mice housed in EE exhibited reduced number of lung metastatic foci compared to control mice housed in a standard environment (SE).

Immunosuppressive Tumor Microenvironment Status and Histological Grading of Endometrial Carcinoma.

The recent successes of new cancer immunotherapy approaches have led to investigate their relevance in the context of the Endometrial Carcinoma (EC). These therapies, that take the tumor-induced immunosuppressive microenvironment into account, target the tumor immune escape, in particular the inhibitory receptors involved in the regulation of the effector T cells' activity (immune checkpoints). The aim of this study was to identify, in ECs, differences in intergrades immune status that could contribute to the differences in tumor aggressiveness, and could also be used as theranostic tools.

CXCR7-mediated progression of osteosarcoma in the lungs.

Background: Osteosarcoma (OS) is the most frequent primary malignant bone tumour in children and adolescents with a high propensity for lung metastasis. Chemokines and chemokine receptors have been described to have an important role in many malignancies including OS. The aim of this study was to investigate the expression of CXCR7 receptor in OS tissues and its role in the progression of the disease in the lungs.

CXCR7 receptors facilitate the progression of colon carcinoma within lung not within liver.

Background: Liver and lung metastases are the predominant cause of colorectal cancer (CRC)-related mortality. Chemokine-receptor pairs have a critical role in determining the metastatic progression of tumours. Our hypothesis was that disruption of CXCR7/CXCR7 ligands axis could lead to a decrease in CRC metastases.

Antagonism of chemokine receptor CXCR3 inhibits osteosarcoma metastasis to lungs.

Metastasis continues to be the leading cause of mortality for patients with cancer. Several years ago, it became clear that chemokines and their receptors could control the tumor progress. CXCR3 has now been identified in many cancers including osteosarcoma and CXCR3 ligands were expressed by lungs that are the primary sites to which this tumor metastasize.

Gastrojejunocolic fistula after gastric surgery for duodenal ulcer: case report.

Gastrojejunocolic fistulae, a late complication of gastroenterostomy, are presently uncommon. Patients can present with symptoms of a fistula 20 years or more after their original gastric surgery. The knowledge of this rare condition can allow prevention, through a better operative strategy and a medical treatment at the phase of stomal ulcer with proton pump inhibitor and Helicobacter pylori eradication.
