Combining PET/CT and EBV DNA to Evaluate the Hazard of Progression in the Follow-up of Locally Advanced NPC
An observational study of Nasopharyngeal Carcinoma, run by Sun Yat-sen University at 1 site in China.
Trial summary
PET/CT and EBV DNA are important in diagnosis of NPC. We consider that combining post-treament PET/CT and plasma EBV DNA may be effective in evaluating the hazard of progression in the follow-up of Locally Advanced Nasopharyngeal Carcinoma. Hence we establish this prospective cohort study. Read more about this study

About this study
Official title: Combining Fluorodeoxyglucose-Positron Emission Tomography/Computed Tomography and Plasma EBV DNA to Evaluate the Hazard of Progression in the Follow-up of Locally Advanced Nasopharyngeal Carcinoma
PET/CT and EBV DNA are important in diagnosis of NPC. We consider that combining post-treament PET/CT and plasma EBV DNA may be effective in evaluating the hazard of progression in the follow-up of Locally Advanced Nasopharyngeal Carcinoma. Hence we establish this prospective cohort study.
Read the detailed description
Newly-diagnosed patients with stage III or IV non-metastatic Nasopharyngeal Carcinoma (AJCC 7th) will be recruited. All subjects receiving chemoradiotherapy will undergo a baseline integrated [18F]fluoro-2-deoxy-D-glucose (FDG) positron emission tomography/computed tomography (PET/CT) scan or traditional follow-up examination and plasma EBV DNA test before the start of chemoradiotherapy.
Patients receiving IMRT treatment will receive a dedicated FDG PET/CT protocol 12 weeks after the end of chemoradiotherapy (primary endpoint).Plasma EBV DNA test will be performed 4, 12, 24 weeks after the end of IMRT treatment. In patients with negative PET/CT results, 2 follow-up visits are required to complement nasopharyngoscope examination and plasma EBV DNA test in the frist year. All patients will undergo annual PET/CT or traditional follow-up examination and plasma EBV DNA test 1 year after completing chemoradiation unless recurrent/residual disease is histopathologically-confirmed.
Patients with a PET/CT result suspecting for residual/recurrent/metastatic tumor must have pathological and/or clinical evidence of tumor existence before salvage therapy is started.

Questions about this trial
What is this clinical trial studying?
An observational study of Nasopharyngeal Carcinoma, run by Sun Yat-sen University at 1 site in China.
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 9 inclusion and 5 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 19 Dec 2020. 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 China. 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 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?
Negative predictive value (NPV) of FDG PET/CT (time frame: 12 weeks after IMRT treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03601390, which also lists 10 linked publications.
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 19 Dec 2020.
