The same is also true probably with higher T stage and co-existing tobacco use. The methods for the detection of p16, HPV DNA, HPV E6/E7 mRNA, anti-E6/E7 antibodies, in tissue, in serum and in saliva of patients, along with their clinical implications are also discussed. SIGNIFICANCE This article provides latest developments on the HPV driven HNSCC. 'Diagnosis of transcriptionally active HPV infection,' 'Modalities for surveillance,' 'Implication of de-escalation of therapy' are some of the critical issues that could serve the medical, the research as well as the patient communities. BACKGROUND With the advent of new treatment options for chronic rhinosinusitis (CRS) comes the ability for physicians to provide more individualized patient care. Physicians are now tasked with identifying who may be the best candidate for a particular therapy. OBJECTIVE To address existing biomarkers and potentially new methods that could guide treatment choices in patients with CRS. DATA SOURCES Published literature obtained through PubMed searches. STUDY SELECTION Studies relevant to inflammatory endotypes, phenotypes, and biomarkers in CRS were included. RESULTS Currently, no clinically validated tools are available to determine the best therapeutic modality for patients with CRS with nasal polyps (CRSwNP) or without nasal polyps (CRSsNP). Patients with CRS can be classified into 3 endotypes based on the presence of type 1, type 2, or type 3 inflammation. CRS endotypes can be influenced by age and geographic location. However, clinical application may be limited because endotyping currently requires basic research laboratory support. Clinical symptoms may also predict inflammatory endotypes with smell loss being indicative of type 2 inflammation. Numbers of t
