Trial summary

Hypoxia and tumor cell proliferation are important mechanisms contributing to resistance to radiotherapy in human head and neck tumor cells. Currently, assessment of these two tumor characteristics is performed in biopsies using immunohistochemical staining and subsequent analysis. Read more about this study

About this study

Official title: Validation of 18F-MISO-PET and 18F-FLT-PET by Immunohistochemical Assessment of Head and Neck Cancer Resection Specimen

Hypoxia and tumor cell proliferation are important mechanisms contributing to resistance to radiotherapy in human head and neck tumor cells. Currently, assessment of these two tumor characteristics is performed in biopsies using immunohistochemical staining and subsequent analysis. A promising non-invasive method of characterizing a tumor is the use of positron-emission tomography (PET). Specific tracers can be used to detect hypoxia and proliferative activity. 18F-misonidazole is a tracer for hypoxia and 18F-thymidine is a tracer for proliferation.

Patients suffering from head and neck cancer and who will undergo surgery will be included in this study.

One week before the surgery the patients will undergo a CT-scan and a PET-scan with either of the tracers. Shortly before the surgery they will be given immunohistochemically detectable marker substances enabling the characterization of the tumor samples gathered from the resection specimen. These markers are pimonidazole for detection of hypoxia and iododeoxyuridine for detection of tumor cell proliferation.

The data collected by PET-scan will be analysed and compared to the results acquired by immunohistochemistry.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 18F-FLT and 18F-MISO-PETProcedure or surgery

    18F-FLT-PET-images will be acquired one hour after injection of 250 MBq FLT. 18F-MISO-PET: 400 MBq FMISO will be injected intravenously. Marker administration: The day before surgery (≤ 24h) pimonidazole (500 mg/m2) will be administered intravenously in 100 ml saline over 20 min. IdUrd (200 mg) will be administered as bolus injection 20 min before surgery.

What is being measured

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

  1. To validate 18F-MISO-PET for detection of tumor hypoxia and 18F-FLT-PET for detection of tumor cell proliferation by immunohistochemical assessment of hypoxia and proliferation in head and neck cancer resection specimen.

    Measured: 1 month

Secondary outcomes (1)
  1. To assess if functional information obtained by 18F-MISO-PET and 18F-FLT-PET can improve the definition of target volume for radiotherapy treatment planning.

    Measured: 1 month

Questions about this trial

What is this clinical trial studying?

An observational study of Head and Neck Neoplasms, run by Radboud University Medical Center at 1 site in Netherlands.

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 3 inclusion and 3 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 7 May 2015. 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 Netherlands. 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: Problems with FMISO supply). 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?

To validate 18F-MISO-PET for detection of tumor hypoxia and 18F-FLT-PET for detection of tumor cell proliferation by immunohistochemical assessment of hypoxia and proliferation in head and neck cancer resection specimen. (time frame: 1 month). 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 7 May 2015.
