- 618
1.Age >18 years.
2.Patients must have histologically or cytologically confirmation of neuroendocrine tumors or any other tumor histology type documented as sst2-positive, that may benefit from receptor radionuclide therapy and for which there aren’t any other effective treatments.
3.Measurable disease according to RECIST 1.1.criteria; also patients without measurable but with evaluable disease can be enrolled.
4.Any disease stage is allowed. Patients with documented disease will be admitted to therapeutic phase only if the diagnostic OctreoScan (the tumour uptake will be evaluated with a 3-grade scale, where 1 = liver uptake, 2 > liver uptake and < kidney uptake and 3 > kidney uptake: only tumour uptakes grade 2 and 3 will be considered for therapy) and/or PET/CT 68Ga-peptide images demonstrate a significant uptake in the tumour.
5.Patients with progressive disease in pre-study period (PD within the last 12 months), refractory to conventional standard treatments; clinical progression is allowed
6.Patients with or without concurrent therapy with somatostatin analogs
7.ECOG performance status <2
8.Adequate haematological, liver and renal function

F.1.3.1 Number of subjects for this age range 208
1.Patients treated with chemotherapy and therapeutic radiotherapy within 4 weeks and treated within 2 weeks with palliative radiotherapy, hormonal or biological therapy).
2.Patients treated with previous radiometabolic therapy with an adsorbed dose to the kidney more than 23 Gy and more than 1.8 Gy for the bone marrow or as surrogate of dosimetry.
3.All acute toxic effects of any prior therapy (including surgery radiation therapy, chemotherapy) must have resolved to a grade = 1 according to National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0 (CTCAE)
4.ECOG performance status >2
5.Participation in another clinical trial with any investigational agents within 30 days prior to study screening.
6.Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
7.Assessed bone marrow invasion > 50% (with Bone Marrow biopsy or instrumental exams i.e bone scan or CT or MRI)
8. Pregnant or breastfeeding women are excluded from the present study
