How Dr. Nghia Nguyen Diagnoses Neuroendocrine Tumors: Epigastric Pain and Change
Dr. Nguyen uses a step-by-step approach:
Medical History and Exam
He reviews your symptoms—especially epigastric pain, bloating, flushing, diarrhea, and unexplained weight loss—and evaluates risk factors such as family history, genetic syndromes, smoking, and alcohol use.
Blood Tests
We measure hormone levels and tumor markers, including chromogranin A, serotonin, insulin, gastrin, and monitor general health indicators like liver and kidney function.
Imaging Studies
- CT and MRI scans to visualize tumors in the stomach, intestines, pancreas, or lungs.
- Somatostatin receptor scintigraphy (Octreoscan) or 68Ga-DOTATATE PET/CT to detect small or metastatic lesions.
- Endoscopic ultrasound for high-resolution imaging and guided sampling of pancreatic or GI tract tumors.
Advanced Testing (if needed)
An EUS-guided fine needle aspiration or surgical biopsy confirms the diagnosis and tumor grade. Genetic testing may be offered when hereditary NET syndromes are suspected.
Frequently Asked Questions
What are the types of NETs?
They include carcinoid tumors, pancreatic NETs, and lung NETs. Each type can behave differently in growth rate, hormone production, and treatment response.
Are NETs a form of cancer?
Yes. Neuroendocrine tumors are cancerous growths arising from hormone-producing cells. Many grow slowly and respond well to therapy.
What are the symptoms?
Symptoms vary by tumor location and hormone activity. Common signs include abdominal pain, flushing, diarrhea, weight loss, hypoglycemia, or respiratory symptoms.
How does Dr. Nguyen treat NETs?
He offers a multimodal approach: nutritional guidance, symptom-controlling medications, minimally invasive procedures, surgery, targeted therapies, or PRRT as needed.
When should I see a specialist?
If you have unexplained hormone-related symptoms, persistent abdominal issues, or imaging/test results indicating a mass, schedule an evaluation with Dr. Nguyen promptly.
Can diet changes alone treat NETs?
No. While dietary adjustments can help manage symptoms, they do not cure NETs. Medical treatments and procedures are often required for disease control.
Will I need surgery?
It depends on tumor size, location, and spread. Some small NETs can be observed or treated medically, while others require endoscopic or laparoscopic removal. Dr. Nguyen will discuss your personalized plan.
