Trial summary

Patients with head and neck cancer will be imaged with PET scan and CT scan in order to determine areas of the tumour that are hypoxic. It is hypothesized that PET /CT will provide information on hypoxia of the tumors and tumor regions in head and neck cancer patients. Read more about this study

About this study

Patients with head and neck cancer will be imaged with PET scan and CT scan in order to determine areas of the tumour that are hypoxic.

It is hypothesized that PET /CT will provide information on hypoxia of the tumors and tumor regions in head and neck cancer patients.

Read the detailed description

Patients with head and neck cancer greater than 3 cm will imaged with PET scan and CT scan in order to determine areas of the tumour that are hypoxic. Following surgical removal, samples of the tumour will be evaluated for the expression of hypoxia genes. The preoperative imaging will be compared to the "gold standard" measures of hypoxic response at the level of gene transcription and a new hypoxia marker with the hypoxyprobe detection system (pimonidazole).

Hypothesis: FDG/PET visualization of glycolysis combined with CT visualization of blood flow will correlate with cellular response to hypoxic stress in head and neck tumors and intra-tumor regions. Measurement of relative levels of mRNAs encoding hypoxia response genes will be performed in cells microdissected from the surgical samples. Good correlation between imaging signals and direct molecular measures of hypoxic response in primary human tumors will provide information necessary to develop treatment strategies that employ targeted, increased radiation to hypoxic tumors.

Pimonidazole is an exogenous nitro-imidazole marker, which can be detected through immunohistochemical analysis of frozen sections. It detects cellular hypoxia upon becoming reduced in cells with low oxygen tension, a property that can be detected through antibody mediated detection of the reduced form. It has also shown to reliably and specifically stain hypoxic regions within the tumor, and to correlate well with patient prognosis and treatment outcome.

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing PET/CT in people with Head and Neck Cancer, run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's at 1 site in Canada.

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 1 inclusion and 8 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: finished, as of the sponsor's last update on 28 Aug 2017. 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 Canada. 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.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

FDG/PET visualization of glycolysis/blood flow in tumors and intra-tumor regions; (time frame: 2 years). The study lists 2 primary outcomes in all. 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 28 Aug 2017.
