Background & Aims: Short-term studies have shown that somatostatin analogues are effective in patients with polycystic kidney and liver disease. We evaluated the long-term effects of long-acting release octreotide (octreotide LAR), a somatostatin inhibitor, vs placebo in these patients.
Methods: We performed a controlled study of adults with polycystic kidney and liver disease (estimated glomerular filtration rate, 40 mL/min/1.73m(2) or more) at a single center in Italy. We analyzed data from 27 patients randomly assigned to groups given octreotide LAR (40 mg, n = 14) or placebo (n = 13) each month for 3 years. The primary outcome was absolute and percentage change in total liver volume (TLV), which was measured by magnetic resonance imaging at baseline, after 3 years of treatment, and then 2 years after treatment ended.
Results: Baseline characteristics were similar between groups. After 3 years, TLV decreased by 130.2 ± 133.2 mL in patients given octreotide LAR (7.8% ± 7.4%) (P = .003) but increased by 144.3 ± 316.8 mL (6.1% ± 14.1%) in patients given placebo. Change vs baseline differed significantly between groups (P = .004). Two years after treatment ended, TLV had decreased 14.4 ± 138.4 mL (0.8% ± 9.7%) from baseline in patients given octreotide LAR but increased by 224.4 ± 331.7 mL (11.0% ± 14.4%) in patients given placebo. Changes vs baseline still differed significantly between groups (P = .046). Decreases in TLV were similar in each sex; the change in TLV was greatest among subjects with larger baseline TLV. No patient withdrew because of side effects.
Conclusions: In a placebo-controlled study of patients with polycystic kidney and liver disease, 3 years of treatment with octreotide LAR significantly reduced liver volume; reductions were maintained for 2 years after treatment ended. Octreotide LAR was well-tolerated. ClinicalTrials.gov number: NCT02119052.

Key Clinical Message: Pancreatic neuroendocrine tumors (PNETs) are rare and often misdiagnosed due to their vague symptoms and tumor heterogeneity. Early detection using computed tomography (CT) is essential, particularly in regions without access to advanced diagnostic tools like immunohistochemistry and genetic testing.
Abstract: Neuroendocrine tumors (NETs) are rare tumors in adults and extremely rare in the pediatric population, as pancreatic NETs (pNETs) have an incidence rate of <0.

Introduction: The somatostatin analogs (SSA) octreotide and lanreotide are a mainstay in the treatment of neuroendocrine tumors (NET). The two pivotal trials differed considerably in terms of patient characteristics and are not directly comparable. Further comparative data are lacking.

Adjuvant therapy for pancreatic neuroendocrine tumors (PanNETs) after radical resection lacks evidence-based data and remains controversial. This study aimed to validate whether long-acting octreotide is a potential candidate for adjuvant therapy in patients with G2 PanNETs at high recurrence risk by clustering real-world data. A retrospective review of patients with nonmetastatic grade 2 PanNETs who underwent radical resection at six research centers between 2008 and 2020 was conducted.
