Brief Summary
In France, since the reimbursement of Lutathera®, this treatment is allowed for retreatment if patients still fulfill the criteria of its indication and 4 news cycles could be proposed. However, clinical practices are heterogeneous regarding the number of new cycles and most teams perform only two additional cycles (every 8 weeks). Therefore, the coordinator propose to evaluate the efficacy of two additional cycle of Lutathera® versus active surveillance in patients already retreated with two cycles Lutathera® for a new progression of intestinal neuroendocrine tumor and who previously received the 4 cycles of treatment with a clinical benefit.

Outcome Measures
Primary Outcomes (1)
Evaluate the efficacy of two additional cycles of Lutathera® (one injection every two months), compared to active surveillance during 6 months in patients already retreated with two cycles.
defined as a change of tumoral assessment (Complete Response, Partial Response and Stable Disease from RECIST v1.1) with an evaluation every 2 months.
assessement every cycle (every 8 weeks) 6 months from randomization
Secondary Outcomes (5)
Evaluate the impact of two additional cycles of Lutathera® (one injection every two months), compared to active surveillance in term of Safety
during 6 months in patients already retreated with two cycles (each cycle is 8 weeks)
Evaluate the impact of two additional cycles of Lutathera® (one injection every two months), compared to active surveillance in term of Progression free survival
the time without progression of disease during 5 years after the treatment,
Evaluate the impact of two additional cycles of Lutathera® (one injection every two months), compared to active surveillance in term of Overall survival
the time without death during 5 years after the treatment
