Casting a Wider NET: Pancreatic Exocrine Insufficiency Induced by Somatostatin Analogues among Patients with Neuroendocrine Tumours? Cancers (Basel) 2023; 15:cancers15071933. [PMID: 37046594 PMCID: PMC10093494 DOI: 10.3390/cancers15071933] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 03/09/2023] [Accepted: 03/20/2023] [Indexed: 04/14/2023] Open
Abstract
Somatostatin-analogues (SSAs) are a first-line treatment of unresectable neuroendocrine tumours (NETs). However, SSAs inhibit pancreatic secretions, which could lead to pancreatic exocrine insufficiency (PEI). PEI is known to be detrimental to patient quality of life and nutritional status. This study aimed to evaluate the effect of SSAs on pancreatic exocrine function in patients with NETs, using the 13C-mixed triglyceride breath test (13C-MTGT). Exocrine function was assessed using the 13C-MTGT at baseline and after a third SSA injection (two months). A quotient of 13CO2/12CO2 was measured by mass spectrometry, and the cumulative percent dose recovered at 6 h (cPDR) is reported. The secondary endpoints investigated were change in weight, HbA1C, and vitamin D levels. Ten patients completed the study. Exocrine function reduced in all patients (n = 10) following SSA therapy (median reduction from baseline: -23.4% (range: -42.1-0.5%, p = 0.005)). vitamin D levels decreased in all but one patient (median decrease from baseline: -26.5%, (-44.7-10%; p = 0.038)), and median HbA1C levels increased by 8.0% (0-59.3%; p = 0.008). Change in weight was not significant (median decrease from baseline: -0.21% (-4.5-3.5%, p = 1.000)). SSA therapy has a consistent impact on exocrine function from early in the treatment course, but the long-term clinical effects of this remain to be defined. Further studies are required to determine the clinical relevance of this observation and optimise the management of PEI in this cohort.

Abstract
INTRODUCTION Lanreotide autogel is a synthetic somatostatin analogue which has been FDA and EMA approved for unresectable, well to moderately differentiated, locally advanced or metastatic gastroenteropancreatic neuroendocrine tumor. Its action is mediated by its affinity to somatostatin receptors, especially sst2 and sst5 receptors. Its longer half-life offers the convenience of 4-week dosing over the need for frequent injections of short-acting somatostatin analogues. Areas covered: Lanreotide ATG offers progression-free survival benefit in locally advanced or metastatic neuroendocrine tumor (NET) compared to placebo, reflecting a strong antiproliferative signal. As lanreotide is commonly used for management of NET, it is imperative to recognize and appropriately manage any drug-related toxicities. In this review, we will provide an overview of the toxicity with lanreotide and its management. Expert opinion: Lanreotide is highly effective in managing carcinoid symptoms and has a robust anti-tumor effect in NET. Overall, it is well tolerated with low rates of treatment discontinuation due to toxicity. It's toxicity profile is mostly predictable, and patients should be informed of the transient nature of some of the upfront toxicities.
