Somatostatin Receptor Imaging in NPC, EBV Related Cancers
October 13, 2022 updated by: National Cancer Centre, Singapore
Somatostatin Receptor Imaging in Nasopharyngeal Cancer, Epstein-Barr Virus (EBV) Related Cancers and Other Rare Tumors
The study aims to describe the avidity of somatostatin receptors in locally advanced, metastatic and locally recurrent nasopharyngeal cancer (NPC) and to determine the proportion of NPC patients with high somatostatin receptor density that may benefit from future somatostatin targeted therapeutic trial plans.
The investigators also aim to determine the presence of somatostatin receptors in other EBV related cancers.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
OTHER: PET imaging
|
Patients will be fasted for 6 hours prior to intravenous injection of 370MBq +/- 10% (18)F-fluorodeoxyglucose.
Scanning will be performed at an interval of at least 60 minutes following the injection.
200MBq +/- 10% Galium-68 DOTATATE will be injected intravenously.
Scanning will be performed approximately 60 minutes after the injection.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Amount of tracer uptake in the tumour lesions of NPC patients
Time Frame: From time of tracer injection to time the scan is performed
|
The maximum standardized uptake values (SUVmax) will be measured.
If the average SUVmax of all the lesions is more than 10, the patient will be considered to have an overall high somatostatin receptor density.
|
From time of tracer injection to time the scan is performed
