This report describes the results of a phase II trial to evaluate the safety, feasibility and response of patients with irresectable, histologically proven, stage II-IV adenocarcinoma of the pancreas receiving high-dose octreotide treatment. Octreotide was self-administered subcutaneously (3 x 2000 micrograms per day) by 49 patients. Therapy was discontinued after progression of the disease. Due to the subseqment diagnosis of bile duct carcinoma and stage I disease, 2 patients were excluded, leaving 47 evaluable patients with measurable disease. The median Karnofsky score was 80%. 3 patients had stage II (6%), 19 stage III (40%), and 25 (53%) stage IV disease. Octreotide treatment resulted in stable disease in 9 patients (19%) for more than 12 weeks. No complete or partial response was observed. The median overall survival was 21.4 weeks and the median progression-free survival 9.0 weeks. Therapy with high-dose octreotide is feasible, well tolerated and might prolong survival. In a placebo-controlled phase III study the effects of octreotide in patients with pancreatic cancer will be confirmed.

Background: Somatostatin analogs (SSAs) binding to and activating somatostatin receptors (SSTRs) have been extensively used for the treatment of neuroendocrine tumors (NETs). The currently approved synthetic SSAs have high affinity for SSTR2 (octreotide/lanreotide), or for SSTR2 and SSTR5 (pasireotide). These agents have shown symptoms control and antiproliferative effects in subsets of NET patients and this was associated to the expression of the targeted SSTRs.

Hypoglycemia is a medical emergency with a multitude of potential causes. Paraneoplastic hypoglycemia represents a rare cause of this condition. Hepatocellular carcinoma (HCC) can result in paraneoplastic hypoglycemia through extensive tumor infiltration and the presence of insulin-like growth factor 2 precursors.

Article Synopsis
- There are no established first-line treatments for higher grade gastroenteropancreatic neuroendocrine tumors (NETs), prompting a study on the effectiveness of Lu-DOTA-TATE (Lu-Dotatate) as a potential option.
- The NETTER-2 trial was a phase 3 study that randomized patients with advanced NETs to receive either Lu-Dotatate plus octreotide or high-dose octreotide alone, focusing on progression-free survival as the main outcome.
- Results showed that patients receiving Lu-Dotatate had a significantly longer median progression-free survival of 22.8 months compared to 8.5 months for those on high-dose octreotide, indicating Lu-Dotatate may

Purpose: Gastroenteropancreatic -neuroendocrine tumours (GEP-NETs) are commonly treated with surgical resection or long-term therapies for tumour growth control. Lutetium [Lu]-DOTA-TATE was approved for the treatment of GEP-NETs after the phase III NETTER 1trial demonstrated improved progression free survival, objective response rates and health-related quality of life (HRQoL) compared to high-dose somatostatin analogues. No real-world data exist on prescribing habits and clinically significant endpoints for [Lu]Lu-DOTA-TATE treatment in Italy.
