The virome of HPV-positive tonsil squamous cell carcinoma and neck metastasis

January 27, 2020

The cover for issue 3 of Oncotarget features Figure 3, "Hierarchical clustering of tonsil squamous cell carcinoma cohorts based on viral signature detection pattern with associated pathological features (perineural invasion (PNI), lymphovascular invasion (LVI), and tumor stage (T stage))," by Carey, et al.

In this prospective study, a pan-pathogen microarray was used to determine the virome of early stage, p16-positive OPSCC and neck metastasis treated with transoral robotic surgery and neck dissection.

The virome findings of primary tumors and neck lymph nodes were correlated with clinical data to determine if specific organisms were associated with clinical outcomes.

This will serve as a foundation for future research investigating the role of the virome in OPSCC.

Dr. Erle S. Robertson Department of Otorhinolaryngology-Head and Neck Surgery, University of Pennsylvania, Perelman School of Medicine, Philadelphia, PA, USA said, "Head and neck squamous cell carcinomas (HNSCCs), including oropharyngeal squamous cell carcinoma (OPSCC), are classically associated with risk factors such as tobacco and alcohol use."

Head and neck squamous cell carcinomas, including oropharyngeal squamous cell carcinoma, are classically associated with risk factors such as tobacco and alcohol use.

HPV-positive OPSCCs have a higher incidence amongst younger patients with higher performance status, lower tobacco consumption, and higher socioeconomic status.

Compared to HPV-negative OPSCCs, HPV-positive OPSCCs have an improved overall survival and disease-free survival, which is at least partially related to the increased sensitivity to chemotherapy and radiation therapy.

The survival advantage of HPV-positivity persists even after adjusting for confounders, suggesting a difference in the tumor biology between HPV-positive and -negative OPSCCs.

The Robertson Research Team concluded, "In summary, specific viruses, including HPV16, are known to impact the tumor biology and clinical behavior of OPSCCs. The virome of HPV-positive OPSCC primary tumors and neck lymph nodes include the virus families Papillomaviridae, Herpesviridae, Baculoviridae, Reoviridae, Siphoviridae, Myoviridae, and Polydnaviridae. Additional studies are necessary to determine if the identified viral signatures correlate with tumor behavior."

Insomnia Line
Coronasomnia is a not-so-surprising side-effect of the global pandemic. More and more of us are having trouble falling asleep. We wanted to find a way to get inside that nighttime world, to see why people are awake and what they are thinking about. So what'd Radiolab decide to do?  Open up the phone lines and talk to you. We created an insomnia hotline and on this week's experimental episode, we stayed up all night, taking hundreds of calls, spilling secrets, and at long last, watching the sunrise peek through.   This episode was produced by Lulu Miller with Rachael Cusick, Tracie Hunte, Tobin Low, Sarah Qari, Molly Webster, Pat Walters, Shima Oliaee, and Jonny Moens.
