The purpose of this study was to investigate the effects of combining the phosphotidylinositol-3-kinase (PI3K) inhibitor buparlisib (BKM)120 with the anti-epidermal growth factor receptor (EGFR) agent cetuximab and radiotherapy (RT) on an orthotopic model of head and neck squamous cell carcinoma (HNSCC).

Background. The gene encoding cortactin, CTTN (locus 11q13), an actin-binding substrate of Src kinases, is frequently amplified in breast and head and neck squamous cell carcinomas (HNSCC) and cortactin overexpression is thought to contribute in a significant way to the invasive phenotype of these tumors. Elevated Epidermal Growth Factor...

Background: France has one of the highest incidence of head and neck cancers in Europe. Despite this, the epidemiological impact of high-risk human papilloma virus (HR-HPV) remains poorly investigated.Methods: we prospective assessed the proportion of oropharyngeal cancers due to HR-HPV in 15 hospitals throughout France. HPV-status was...

Dysregulation of extracellular matrix (ECM) deposition and cellular metabolism promotes tumor aggressiveness by sustaining the activity of key growth, invasion, and survival pathways. Yet mechanisms by which biophysical properties of ECM relate to metabolic processes and tumor progression remain undefined. In both cancer cells and...

Highlights d AXL and c-MET are overexpressed in radiotherapy-and cisplatin-resistant HNSCC d Overexpression of AXL and c-MET contributes to tumor aggressiveness and poor prognosis d Cabozantinib has anti-tumor and anti-metastatic efficacy in mice and zebrafish models d Cabozantinib efficacy is shown on HNSCC biopsies and in one patient after...

Free-flap mandibular reconstruction is a highly specialized procedure associated with severe complications necessitating re-interventions and re-hospitalizations. This surgery is expensive in terms of health workers' time, equipment, medical devices and drugs. Our main objective was to assess the direct hospital cost generated by osseocutaneous...
