Cohort-level clinical trajectory and molecular landscape of idiopathic subglottic stenosis for precision laryngology-a study of the Canadian airways research (CARE) group.

Background: First described in 1972, idiopathic subglottic stenosis (iSGS) is a serious chronic orphan disease characterised by recurrent scarring of the subglottis. Although the cause is unknown, iSGS is almost exclusively restricted to Caucasian females typically in their fourth to sixth decade. However, given its rare incidence (1:400,000), understanding the clinical trajectory and molecular factors associated with iSGS disease development and prognosis has been difficult.

Tumor Cell Extrinsic Synaptogyrin 3 Expression as a Diagnostic and Prognostic Biomarker in Head and Neck Cancer.

Over 70% of oropharyngeal head and neck squamous cell carcinoma (HNSC) cases in the United States are positive for human papillomavirus (HPV) yet biomarkers for stratifying oropharyngeal head and neck squamous cell carcinoma (HNSC) patient risk are limited. We used immunogenomics to identify differentially expressed genes in immune cells of HPV(+) and HPV(-) squamous carcinomas. Candidate genes were tested in clinical specimens using both quantitative RT-PCR and IHC and validated by IHC using the Carolina Head and Neck Cancer Study (CHANCE) tissue microarray of HNSC cases.
