About this study

The study will utilize both retrospective and prospective data collection from patients that already had a bronchoscopy and lung resection or will have a bronchoscopy and lung resection for squamous cell carcinoma. The investigators plan to prospectively collect 5 bronchoscopic biopsies, 10ml blood and one tumor and adjacent normal samples from 200 qualified patients who meet the study criteria.

Read the detailed description

The study will utilize both retrospective and prospective data collection from patients that have already had a bronchoscopy and lung resection or will have a bronchoscopy and lung resection for squamous cell carcinoma. The investigators plan to prospectively collect 5 bronchoscopic biopsies, 10ml blood and one tumor and adjacent normal samples from 200 qualified patients who meet the study criteria. If a patient has already had a bronchoscopy and has consented to have samples stored for research at the Mayo Clinic Rochester we will access them for the research study if available. Otherwise, if the patient has already had surgery and tissue has not been stored for research the investigators will consent patients to use their clinical specimens for the research study. The investigators will then extract DNA from tissue sections and blood and use a custom targeted sequencing panel of 23 cancer driver genes with significant mutations in squamous cell carcinoma that they have developed to find the prognostic biomarkers. The DNA will be used in a PCR reaction to generate amplicons for library preparation using Illumina Nextera XT library preparation protocol and targeted sequencing on the Illumina Hiseq sequencer. The reads will be aligned to the HG19 using BWA aligner and variant detection performed with Agilent SureCall and GATK analytic tools.

Tissue CollectionWe plan to prospectively collect 5 bronchoscopic biopsies, 3ml blood and one tumor and adjacent normal samples from 200 qualified patients who meet the study criteria. If a patient has already had a bronchoscopy and has samples available that were previously collected and stored for research at the Mayo Clinic we will use those samples.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number and types of recurrent genomic alterations evaluated by a custom targeted sequencing panel.

    The aim of this study is to identify and characterized recurrent genomic alteration found in invasive squamous cell carcinoma that are present in the precursor airway epithelial tissues but absent in normal tissues examined from samples taken during a lung procedure.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Carcinoma, Squamous Cell and Carcinoma, Squamous, run by Mayo Clinic at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 14 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Lack of funding, slow accrual). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number and types of recurrent genomic alterations evaluated by a custom targeted sequencing panel. (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Oct 2025.
