We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
After signing consent, patients will be in the Nuclear Medicine department for approximately 3 hours. The intervention is a one-off injection of [18-F]-FMISO (dosage 300-350MBq), administered by the technologist. Imaging will be a mix of dynamic and static acquisitions from the time of injection to 120 minutes after injection. Standard PET machine settings will otherwise be used.

Secondary outcome [1] 353443 0
Distribution of FMISO in target lesion and other tumour lesions - quantitative (SUVmax, peak, mean; ratio of uptake in target versus uptake in normal tissue of same organ) and qualitative assessment (geographical pattern of uptake in lesions). This is a composite outcome.

Key inclusion criteria
1) Patients 18 years of age or older with metastatic neuroendocrine neoplasm (NEN) and histological confirmation who have undergone PET scans at Royal North Shore Hospital
2) Patients identified by the nuclear medicine physicians as having a lesion with 68Ga-DOTATATE PET (DOTA) avidity on the periphery but not the centre of the lesion (i.e. lack of avidity in the hole of the “donut“-like tumour).
Minimum age
18 Years
Maximum age
No limit
Both males and females
Can healthy volunteers participate?
Key exclusion criteria
1) Patients who have not received a PET scan at RNSH
2) Patients without a histological diagnosis of metastatic NEN
3) Inability to lie in a supine position on the PET scanning bed for 15 minutes;
4) Subjects who required sedation for their baseline clinical PET scan;
5) Renal failure requiring haemo- or peritoneal dialysis;
6) Substance abuse, medical, psychological or social conditions that in the opinion of the investigator may interfere with the patient’s participation in the study or evaluation of the study results;

Brief summary
The purpose of this study is to examine the area around a neuroendocrine tumour using a scan called FMISO PET.

Who is it for?
You may be eligible for this study if you are aged 18 or over, and have a metastatic neuroendocrine tumour (NET).

Study details
All participants in this study will undergo one FMISO PET. The scan requires injection of a chemical called a tracer through a needle in the arm. The scan takes approximately 2 hours with the whole study visit on the day taking approximately 3 hours.

It is hoped this research will help clinicians understand the biology of NET better, and help improve health outcomes in the long term as a result of this improved understanding.
