Multicenter, non-interventional, retrospective/prospective biological study on patients affected by head and neck tumors, for which the collection and use of tissue samples, blood and saliva for the detection of HPV-DNA/RNA and miRNA.
For each patient they will come collected tissue, blood and saliva samples. In particular, as regards tissue collection, tumor and neighboring tissues will be used healthy specimens taken during surgical removal, according to clinical practice.
The fresh tissues thus collected will be stored in RNA-later before freezing at - 80°C.
Furthermore, blood and saliva samples will be taken at different times, in particular:
i) the day before surgery; ii) the day after surgery (only for blood); iii) at the time of patient discharge (approximately 15 days after surgery); iii) during the check-up visit scheduled to monitor the patient's follow-up (FU): every 3 months for the first 2 years and every 6 months for the following 3 years.
The samples will then be used to carry out nucleic acid extraction, the DNA will instead be used to detect the presence of HPV.

| Collection and use of tissue samples, blood and saliva | Diagnostic Test | For tissue collection, tumor and surrounding tissues will be used healthy specimens taken during surgical removal, according to clinical practice. Blood and saliva sampling will be carried out at different times: i) the day before surgery; ii) the day after surgery (only for blood); iii) at the time of patient discharge (approximately 15 days after surgery); iii) during the check-up visit scheduled to monitor the follow-up (FU) |
| Measure | Description | Time Frame |
|---|---|---|
| Identification of biomarkers | The samples that will be collected in this study will be used to carry out nucleic acid extraction. In particular, the extraction of RNA and DNA from tissue samples will be carried out using the "All prep RNA/DNA miRNA universal kit" kit (Qiagen), while from blood and saliva samples it will be carried out respectively through the use of the "DNAeasy blood and tissue kit" (Qiagen) and the "Magmax Total RNA extraction kit" (Thermofisher), following the instructions given in the relevant protocol. The expression of tissue and circulating microRNAs will be evaluated by qRT-PCR analysis using the Taqman method (Life Technology), digital-PCR (dPCR) and Luminex platform (the latter at the IRCSS G Paolo II Tumor Institute of Bari). In particular, the use of dPCR will be necessary for those low-abundance circulating miRNAs which, with the qRT-PCR methodology, are not detectable. | 24 months |
| Measure | Description | Time Frame |
|---|---|---|
| Evaluate HPV-DNA expression as biomarkers. | The DNA will be used to detect the presence of HPV and will be analyzed using dPCR and the Luminex platform. These methods are able to absolutely quantify the number of viral genomes present in the sample and also to evaluate the physical state of the virus: episomal, integrated or mixed.. | 24 months |

Patients suffering from head and neck tumors, recruited in a manner consecutive among those who underwent surgery at the ENT UOC of the IRE between January 2019 and December 2021 and for which, at the start of the study, archive samples as well as i follow-up data up to at least one year after surgery. The biological samples of the cohort selected include both fresh tissue and liquid biopsy (blood and saliva) samples.
