Saliva can be used to treat head and neck cancer

Madrid, 24 (SERMIMEDIA) A multidisciplinary study initiated by the "Barcelona Hospital" clinic showed that saliva can predict the evolution and response.

A study carried out by a hospital in Barcelona showed that Salca can help the development and response to the treatment of head cancer and headaches.The results were reported this Friday at the 76th Spanish Oporhinolaryngologymoologymoogymoogymoogymoogymoogymoogymoogymoogymoogymoogymoogyrogymogla and head and neck and neck today and work today in Madrid.

A group of adolescent students reports to the scientific community, farmers are microenvironments of microenvironments, tumors and other bioenvironmental reports and information on adolescent therapy.

The most common subtype is head and neck squamas Cell Carcinoma (HNSCC), accounting for approximately 90% of cases, which is one of the large challenges of onlinical diversity.

At the moment, there are no reliable markers that allow us to predict which patients with head and neck cancer - of which more than 7000 new cancers will appear in Spain this year alone - will respond best to a particular treatment.This uncertainty makes therapeutic personalization and improvement of clinical outcomes difficult.

Traditionally, the analysis of tumors that are seen through tissue transport as necessary steps is different, not difficult and not the same.

With this in mind, a new method developed by this group of Spanish researchers proposes the use of "salivary fluid biopsy", a non-invasive, painless and easily repeatable that can allow the growth of the tumor over time.

Indeed, otolaryngologist and head of the Department of Head and Neck Tumors at the Clinica Hospitals de Barcelona and principal investigator of the study, Dr. Francesc Javier Aviles Jurado, explained: "These preliminary results confirm that saliva is not just a passive reflection of the oral cavity, but can tell us how it interprets the tumor. It responds to treatment."

"Our multiomic approach allows us to advance toward a comprehensive understanding of the tumor, its environment, and noninvasive prognostic biomarkers that may change the clinical management of head and neck cancer."

In recent research, three bacterial genera stand out - Lunamonas, Actinobacteria and Prevotella - whose presence and activity appear to be related to the development of tumors.

Therefore, some bacteria present in saliva and some metabolic pathways can influence the behavior of the tumor, modulating its severity and its ability to respond to treatment.If this connection is confirmed, saliva could become a molecular mirror of the tumor, providing basic information about its development without the need to resort to invasive procedures.

The research team is currently working to validate larger-scale findings and develop predictive models based on artificial, molecular and microbiological data.
