Inclusion criteria

Inclusion criteria: - >=18 years old - Histologically confirmed low and intermediate grade NET - Metastatic or unresectable disease - Measurable disease on [68Ga]-DOTATATE PET-scan - WHO performance status less than 2 - Life expectancy more than 3 months - Long-acting lanreotide treatment for at least 4 months

Design outcomes

Primary

MeasureTime frame
To visualize and quantify the difference in somatostatin receptor occupancy directly before and after lanreotide injection.

Secondary

MeasureTime frame
a. To assess a correlation between tumor [68Ga]-DOTATATE uptake and size in relation to lanreotide binding. b. To assess differences in [Ga68]-DOTATATE uptake and behavior (reaction to lanreotide) between different metastasis in 1 patient. c. To assess the differences in uptake in normal tissue (thyroid, spleen, liver etc.) before and after lanreotide. d. To assess the correlation between clinical symptoms, receptor occupancy, and tumor markers.
