About this trial
This study aims to determine whether dysbiosis actively contributes to HNSCC and if so, the underlying molecular mechanisms.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Subjects equal to or above the age of 18.
Patients who are seen and evaluated by a provider within the adult Otolaryngology clinic at the University of Colorado Health.
Patients that present with a diagnosis of OSCC.
An equal number of age-matched patients who are visiting the clinic for reasons other than OSCC diagnoses, as the control group.
Disqualifiers
Subjects under the age of 18 or over the age of 100
Subjects unwilling to particiapte
Trial population
We aim to enroll 60 patients total - 30 with oral squamous cell carcinoma (OSCC) who are treatment naïve, and 30 who are non-OSCC control patients, who will be age matched to their OSCC counterparts. Estimates show that Dr. Goddard's practice sees approximately 3 treatment naïve OSCC cases per month. We estimate that we can enroll 30-40 of these cases and an equal number of controls in the first 18 months of this study.

Treatments tested in this trial
Metagenomic sequencing
Diagnostic testShotgun metagenomic sequencing will characterize cancer-associated changes in microbial functional capacity and species/strain-level taxonomic profiles. Metagenomics will provide data on microbial functional capacity along with broader taxonomic classifications.
Metabolic analysis
Diagnostic testMetabolic analysis will be conducted using LC/MS-based metabolic analysis. A targeted approach will quantify a panel of 30 compounds including Trp pathway products while a non-targeted approach, when applied to both lipid and aqueous phase compounds, will profile relative changes in compounds that may influence host

Trial outcomes
Primary outcomes
Characterize human dysbiosis
Stool and saliva samples will be collected from participants, allowing us to reproduce human dysbiosis and analyze whether HNSCC affects one's microbiome composition. Metagenomic sequencing will be conducted through use of DNA extraction, library generation and Illumina sequencing. At least 30 million paired-end 2x150bp metagenomic reads will be generated per sample using the Illumina NovaSeq platform.
Characterize human metabolomics
Through our stool and saliva samples we will be able to characterize metagenomic and metabolic signatures in treatment naïve OSCC and non-OSCC patients. Metabolic analysis will be conducted using LC/MS-based metabolic analysis. A targeted approach will quantify a panel of 30 componds including Trp pathway products, while a non-targeted approach, when applied to both lipid and aqueous phase compounds, will profile relative changes in compounds that may influence host and metabolic and immune statuses.
Integrative multi-omic data analysis and biomarker discovery
We expect to find that specific sets of microbial and host factors interact with each other to promote OSCC.
Secondary outcomes
Impact of human dysbiosis on OSCC development in mice
Freshly collected saliva and stool samples from 10 subjects of each treatment category will be used to reconstitute microbiota.
Monitor tumor size
Tumor size (both weight and size) will be monitored using Bli-imaging. These measures will be assessed between treatment groups by ANOVA or analysis of variance testing.
