Gastric neuroendocrine tumors, comprising roughly 8% of all neuroendocrine tumors, are rare and primarily affect the gastrointestinal tract. These tumors are diagnosed in approximately 4 out of every 100,000 individuals, with most cases occurring in those aged between 55 and 65. The increasing prevalence highlights the urgent need for targeted therapies that specifically attack cancer cells. In response, pharmaceutical companies and research institutions are actively exploring innovative drugs and treatment strategies to improve outcomes for this uncommon condition.

Gastric Neuroendocrine Tumors: Introduction
Gastric neuroendocrine tumors are uncommon cancers that develop from hormone-producing cells within the lining of the stomach. These tumors are characterised by symptoms such as abdominal discomfort, persistent nausea, unintentional weight loss, and hormone-related syndromes, which can vary based on the type and progression of the tumor. While early-stage gastric neuroendocrine tumors are generally slow-growing, advanced cases may become aggressive and spread to other areas. Treatment options encompass somatostatin analogues, targeted therapies, and chemotherapy, specifically tailored to the tumor's features. Early diagnosis and a personalised therapeutic approach are essential for improving clinical outcomes. Current research is focused on innovative therapies, including immunotherapies and peptide-based treatments, to address the significant unmet needs of patients with advanced gastric neuroendocrine tumors.
Gastric Neuroendocrine Tumors Treatment Overview
Gastric neuroendocrine tumors are classified into three types based on their association with gastrin production and malignancy risk. Type 1 is generally benign, while types 2 and 3 are more aggressive and often linked to malignancies. Early diagnosis is critical to improve prognosis and reduce complications.
Treatment options for gastric neuroendocrine tumors depend on tumor type, size, and stage. They include endoscopic or surgical resection for localized tumors and somatostatin analogues for hormone-related symptoms. Advanced cases may require targeted therapies, chemotherapy, or immunotherapies to manage disease progression and improve survival rates.

Gastric Neuroendocrine Tumors Drug Classes
Gastric neuroendocrine tumor treatments utilise a range of drug classes, each designed to target specific pathways and mechanisms involved in cancer growth and survival. These diverse classes enhance the effectiveness of therapy and contribute to personalised treatment strategies. Understanding these drug classes is essential for optimising patient outcomes.
- Small Molecule
Small molecules are low molecular weight compounds designed to interfere with specific molecular pathways critical to tumor growth and progression. These therapies target processes such as cancer cell proliferation, angiogenesis, and survival, making them particularly useful in advanced gastric neuroendocrine tumors. Their systemic effects allow them to reach distant tumor sites, providing broad coverage and effectiveness. By disrupting the signals that drive tumor development, small molecules offer a promising targeted approach to managing aggressive and metastatic cases.
- Monoclonal Antibody
Monoclonal antibodies are engineered proteins specifically designed to recognise and bind to tumor antigens or cellular pathways that contribute to cancer growth. These therapies work by either blocking the signals that promote tumor development or enhancing the immune system's ability to identify and destroy cancer cells. For gastric neuroendocrine tumors, monoclonal antibodies have shown effectiveness in targeting aggressive forms of the disease, offering a precision-based therapeutic option to complement existing treatments and improve patient outcomes.
- Peptide
Peptide-based therapies consist of short chains of amino acids designed to target specific receptors or pathways involved in tumor progression. In gastric neuroendocrine tumors, peptides such as somatostatin analogues regulate hormone production, alleviating symptoms like flushing and diarrhoea caused by hormone overproduction. These therapies are highly specific, reducing off-target effects and improving patient outcomes. Ongoing research focuses on enhancing their therapeutic potential, offering promising solutions for managing both symptoms and disease progression in advanced cases.
- Polymer
Polymer-based therapies utilise advanced drug delivery systems to enhance the efficacy and safety of treatments for gastric neuroendocrine tumors. These carriers enable controlled and sustained drug release, ensuring targeted delivery to tumor sites while minimising systemic toxicity. Polymers can also encapsulate multiple therapeutic agents, allowing for combination treatments with improved outcomes. Their versatility makes them an essential tool in optimising existing therapies and developing innovative approaches to manage advanced or treatment-resistant gastric neuroendocrine tumors effectively.
Gastric Neuroendocrine Tumors- Pipeline Drug Profiles
This section provides an overview of the various drugs used to treat gastric neuroendocrine tumors. It covers their classifications, mechanisms of action, and methods of administration, offering essential insights for effective treatment strategies.
- Pasireotide
Pasireotide is a somatostatin analogue that binds to multiple somatostatin receptor subtypes, effectively regulating hormone secretion in gastric neuroendocrine tumors. This drug is particularly beneficial for managing hormone-related symptoms such as severe diarrhoea and flushing, significantly improving patient quality of life. Current research suggests that pasireotide may also reduce tumor growth and progression, particularly in advanced or metastatic cases. Its broad receptor affinity makes it a promising option in both symptom control and disease management for gastric neuroendocrine tumors patients.
- Nivolumab
Nivolumab is an immune checkpoint inhibitor targeting the PD-1 protein, which enhances the immune system’s ability to detect and destroy cancer cells. It is being studied for its efficacy in advanced gastric neuroendocrine tumors, especially in patients with refractory or metastatic disease. Early clinical trials have demonstrated promising results, including extended survival rates and durable responses. As a novel immunotherapy, nivolumab represents a significant step forward in the treatment of challenging cases of gastric neuroendocrine tumors.
- Lanreotide
Lanreotide is a somatostatin analogue widely used to manage hormone secretion in gastric neuroendocrine tumors. It effectively alleviates symptoms associated with hormone overproduction, such as flushing and diarrhoea, while also slowing disease progression. Clinical studies have confirmed its role in stabilising tumor growth, making it a critical treatment option for patients with advanced or metastatic gastric neuroendocrine tumors. Lanreotide’s sustained-release formulation offers convenient dosing, improving patient adherence and overall treatment experience.
