Introduction: Photochemical Internalization is a novel drug delivery technology for cancer treatment based on the principle of Photodynamic Treatment. Using a photosensitizer that locates in endocytic vesicles membranes of tumor cells, Photochemical internalization enables cytosolic release of endocytosed antitumor agents in a site-specific manner. The purpose of the present in-vitro study was to explore whether Photochemical Internalization is able to enhance the efficacy of Ranpirnase, a cytotoxic amphibian ribonuclease, for eradication of squamous cell carcinoma of the head and neck...

BACKGROUND: Detection of metastatic spread of head and neck cancer to cervical lymph nodes is essential for optimal design of therapy. Undetected metastases lead to mortality, which can be prevented by better detection methods. METHODS: We analysed 41 lymph nodes from 19 patients with oral squamous cell carcinoma (OSCC). Each lymph node was divided in two, one half processed for histopathology and the other half dissociated into single-cell suspension, stained for the carcinoma cell markers cytokeratin 5/8 (CK5/8), epithelial cell adhesion molecule (EpCAM) and epithelial mucin (MUC-1), and analysed with flow cytometry...

Insulin-like peptide 7 (INSL7) or relaxin-3 is a member of the insulin superfamily that is recently discovered. This hormone interacts with relaxin family peptide receptor 3 (RXFP3). Although recent studies of INSL7 have focused on its function in the brain as a neuropeptide, spermatozoa may be a candidate target of INSL7 due to its detection in testes and contains binding sites. Therefore, this study aims to analyse the expression and localisation of RXFP3 on human spermatozoa and to assess the effect of INSL7 on human sperm motility...

Background: Dystrophic calcification can occur in any soft tissue with the absence of a systemic mineral imbalance and is often associated with trauma, infection, or inflammation. It is easily found in the site of the heart and skeletal muscles and rarely appears in the head and neck area. Case report: We present a rare case of multiple calcified masses in the left masseter muscle of a 26-year-old female with a history of trauma in the area. In computed tomography, multiple radiopaque masses were observed inside the left masseter muscle and blood test results were normal...

Acquired resistance to cetuximab, an antibody that targets the epidermal growth factor receptor (EGFR), impacts clinical benefit in head and neck, and colorectal cancers (CRC). One of the mechanisms of resistance to cetuximab is the acquisition of mutations that map to the cetuximab epitope on EGFR and prevent drug binding. We find that necitumumab, another FDA approved EGFR antibody, can bind to EGFR that harbors the most common cetuximab resistance substitution, S468R (or S492R, depending on the amino acid numbering system)...

Fibroblasts play a central role in tumor invasion, recurrence, and metastasis in head and neck squamous cell carcinoma. The aim of this study was to investigate the influence of tumor cell self-produced factors and paracrine fibroblast-secreted factors in comparison to indirect co-culture on cancer cell survival, growth, migration, and epithelial-mesenchymal transition using the cell lines SCC-25 and human gingival fibroblasts. Thereby, we particularly focused on the participation of the fibroblast-secreted transforming growth factor beta-1...

Cetuximab is a monoclonal antibody against epidermal growth factor receptor and is used in the treatment of head and neck cancer, non-small cell lung cancer, and colorectal cancer. This case report describes a rare (<1% incidence) side effect of cetuximab administration: aseptic meningitis. We report a case which is, to our knowledge, the only case at the time of submission of this manuscript of aseptic meningitis in a patient being treated for metastatic colon cancer who was not cetuximab-naïve. This case report may help inform clinicians about the identification and outcome of this adverse event...

Human cancer cell lines are the most frequently used preclinical models in the study of cancer biology and the development of therapeutics. Although anatomically diverse, human papillomavirus (HPV)-driven cancers have a common etiology and similar mutations that overlap with but are distinct from those found in HPV-negative cancers. Building on prior studies that have characterized subsets of head and neck squamous cell carcinoma (HNSCC) and cervical squamous cell carcinoma (CESC) cell lines separately, we performed genomic, viral gene expression, and viral integration analyses on 74 cell lines that include all readily-available HPV-positive (9 HNSCC, 8 CESC) and CESC (8 HPV-positive, 2 HPV-negative) cell lines and 55 HPV-negative HNSCC cell lines...

Purpose: TWIST is a critical factor for predicting prognosis in several human cancers. Here, we study the prognostic significance of TWIST1 and TWIST2 in Head and Neck squamous cell carcinoma (HNSCC) as well as interactions of TWISTs with both gender and smoking in patient survival. Methods: upper quartile normalized RNA-seq V2 RSEM values of TWIST1 and TWIST2 expressions were retrieved from a TCGA HNSCC dataset. Kaplan-Meier survival curves were used to assess the associations of TWIST1 and TWIST2 with patient survival, and multivariate Cox proportional hazards regression models were used to estimate the hazards ratios (HRs) and their 95% confidence intervals (CIs)...

REVIEW
Solange Peters, Keith M Kerr, Rolf Stahel
Non-small cell lung cancer (NSCLC) is one of the most prevalent cancers and is responsible for a large proportion of all cancer-related deaths. Current treatment options are inadequate, reflecting a substantial unmet clinical need. Increasing knowledge regarding the mechanisms and genetic aberrations underlying tumor development and growth has heralded a new era of therapy in oncology, moving away from indiscriminate cytotoxic chemotherapy toward more finely focused, targeted medicine. The development of small-molecule drugs and monoclonal antibodies directed toward specific components of dysfunctional molecular or immune pathways, and mutated genes specific to particular cancer types, is leading the field to more personalized and less toxic treatment options, many of which have demonstrated greater efficacy and survival benefits than their chemotherapeutic counterparts...
