The patient underwent cytoreductive debulking surgery, achieving approximately 70% tumor reduction, followed by long-acting octreotide therapy...This case report underscores the importance of early recognition and a multidisciplinary approach in managing indolent neuroendocrine tumors with multisite metastases. Combined surgical and medical strategies, including debulking surgery and octreotide therapy, can achieve durable disease control and favorable outcomes.

Treatment with somatostatin, cortistatin, octreotide or pasireotide did not exert clear antitumoral effects on model cell lines...Molecular analysis revealed a generalized dephosphorylation affecting key proliferation, growth and cell survival pathways in response to BIM-23120 (unlike when treating with octreotide). Altogether, our results provide novel information on the status of the somatostatin system in PPGL and identify new potential therapeutic tools selectively targeting somatostatin receptors on this refractory tumor.

Clinical management often requires a multimodal approach including titration of DA to higher than usual doses, surgical resection or debulking, and targeted radiotherapy. Robust evidence is lacking for non-approved adjunct therapies, such as aromatase inhibitors and estrogen receptor modulators, although the somatostatin receptor ligand pasireotide may have potential in select patients.

The human insulinoma-derived NT-3 cell line and the murine AtT-20 corticotroph cell line, both expressing SSTR2 and SSTR5, were treated with 1-50 nM of the novel SRLs or reference agents (octreotide, pasireotide)...Dual SSTR2/SSTR5 agonists exhibit antisecretory and antiproliferative activity in NET models that was similar or even superior to reference SRLs. These findings support their further development as next-generation SRLs for SSTR2/5-expressing tumors.

PRRT combined with everolimus-based immunosuppression has demonstrated controllable safety and preliminary antitumor activity in patients with relapsed NETLM after LT who have been strictly screened, but myelosuppression requires close monitoring and timely symptomatic treatment.
