#1
Marco Matejcic, M J Gunter, Pietro Ferrari
Alcohol is a major risk factor for oesophageal squamous cell carcinoma (OSCC), the most prevalent histological subtype of oesophageal cancer (OC) worldwide. The metabolism of alcohol is regulated by specific enzymes whose activity and expression is influenced by genetic polymorphisms. We conducted a systematic review of current epidemiological evidence of the relationship between alcohol intake and OC risk, including the role of tobacco smoking and functional polymorphisms of dehydrogenases (ADHs) and aldehyde dehydrogenases (ALDHs)...

Squamous cell carcinoma (SCC) is the sixth most frequent malignant tumor of the head and neck region. Despite advances in therapeutic options over the last decades, the rate of mortality and morbidity has not been improved markedly. A small subset of cells, cancer stem cells (CSCs), with self-renewal properties have become a major focus of current cancer research. CD44 and p63 are identified as candidate stem cell markers in normal squamous epithelium and SCC. The role of these markers in oral squamous cell carcinoma (OSCC) is still debatable...

Evidence of cancer cells that bear attributes analogous to those of normal stem cells has developed a hierarchical model of cancer's architecture and progression. This subset of cancer stem cells (CSCs) drives the progression and therapy resistance of cancers. Research to identify the phenotypes of these CSCs presents evidence of a subpopulation that is more resistant to therapy and may proliferate in response. Literature shows that CSCs typically represent around 1%-10% of cell populations in head and neck cancer but this proportion may increase in response to a therapeutic radiation dose...

Optical coherence tomography (OCT) is a real-time, cross-sectional optical imaging technology. It is analogous to ultrasonography, except that OCT uses light waves instead of sound waves, and can provide three-dimensional morphological images of living tissues with a micrometer resolution. Through the use of endoscopes, needles, catheters and laparoscopes, OCT has demonstrated tremendous imaging potential in tumor surgery. The current studies suggest that OCT has potential for clinical applications in the following fields of gastrointestinal tumor surgery: (1) Early tumor detection and diagnosis: OCT can distinguish differences between polyp tissue, normal tissue and malignant tissue...

Podoplanin/Aggrus, known as a platelet aggregation-inducing factor, is frequently overexpressed in lung squamous cell carcinomas (LSCC) and glioblastomas among other tumours, and its expression has been reported to be correlated with poor prognosis. However, the contribution of podoplanin to malignant progression has been elusive. Here we demonstrate that in podoplanin-positive LSCC cells, their growth was abrogated by podoplanin knockout in vivo but not in vitro. Conversely, ectopic expression of podoplanin promoted cell growth in vivo and facilitated intratumoral platelet activation...

The microbiome is fundamentally one of the most unique organs in the human body. Dysbiosis can result in critical inflammatory responses and result in pathogenesis contributing to neoplastic events. We used a pan-pathogen array technology (PathoChip) coupled with next-generation sequencing to establish microbial signatures unique to human oral and oropharyngeal squamous cell carcinomas (OCSCC/OPSCC). Signatures for DNA and RNA viruses including oncogenic viruses, gram positive and negative bacteria, fungi and parasites were detected...
