ELTD1-An Emerging Silent Actor in Cancer Drama Play.

The epidermal growth factor, latrophilin, and seven transmembrane domain-containing protein 1 (ELTD1), is a member of the G-protein coupled receptors (GPCRs) superfamily. Although discovered in 2001, ELTD1 has been investigated only by a few research groups, and important data about its role in normal and tumor cells is still missing. Even though its functions and structure are not yet fully understood, recent studies show that ELTD1 has a role in both physiological and pathological angiogenesis, and it appears to be a very important biomarker and a molecular target in cancer diseases. Upregulation of ELTD1 in malignant cells has been reported, and correlated with poor cancer prognosis. This review article aims to compile the existing data and to discuss the current knowledge on ELTD1 structure and signaling, and its role in physiological and neoplastic conditions.

Assessment of efficacy of dendritic cell therapy and viral therapy in high grade glioma clinical trials. A meta-analytic review.

In recent years, immunotherapy has raised the interest of many studies and provided different perspectives for the therapeutic management of high grade glioma. Our meta-analysis focused on the effectiveness of dendritic cell (DC) therapy and viral therapy (VT) in clinical trials. Fourteen eligible studies have been evaluated and the results suggest the improvement of both OS (HR = 0.65) (p < 0.0001) and PFS (HR = 0.59) (p = 0.01) for patients receiving DC therapy. The data for VT showed a slight improvement in terms of OS (HR = 0.81), while PFS was similar to the control arms (HR = 1.06) (p = 0.41).

Current and emerging EGFR therapies for glioblastoma.

Glioblastomas (GBMs) are the most lethal and hard to treat malignancies in clinical practice. The standard of care for treating GBM involving surgery and adjuvant radiotherapy and concomitant temozolomide (TMZ) has remained virtually unchanged in the past decade. Molecular targeted therapies against cancer-specific structures have reported mediocre results in the treatment of GBM, due to multiple factors such as the presence of the blood brain barrier or a vast array of molecular alterations which greatly hinder the action of the most therapeutic agents. One such therapy is directed against the epidermal growth factor (EGF) and its' receptor (EGFR) using either monoclonal antibodies or tyrosine kinase inhibitors. Even though anti-EGF/EGFR treatment produced encouraging results in other forms of cancer it failed to present any clinical benefit for patients with GBM. Lately, immunotherapies that focus on using the host's own immune system against cancer cells have gained popularity, with approaches like peptide vaccination being successfully used in clinical trials for different types of malignancies. These immune-based therapies could hold the key to improving both the prognosis and quality of life for patients suffering for cancers previously considered incurable, such as GBM.
