January 7, 2024by Dr. S. F. Czar0


Patient: John, a 58-year-old with a history of heartburn and chronic indigestion.

Symptoms: Worsening heartburn, abdominal pain, weight loss, and fatigue.

Diagnosis: Endoscopy and biopsies reveal gastric adenocarcinoma, a . Further tests show elevated gastrin levels, suggesting Zollinger-Ellison syndrome (ZES).stomach cancer

The Malignant Melody: Genetic testing confirms John has a mutation in his G cells, causing uncontrolled gastrin production. This excess gastrin stimulates acid and enzyme release, damaging his stomach lining and promoting cancer growth.

Treating the Discord:

  • Medication: John receives a gastrin receptor blocker to suppress acid production and prevent further tumor growth.
  • Surgery: A partial gastrectomy removes the cancerous portion of his stomach.
  • Targeted Therapy: John undergoes treatment with a gastrin monoclonal antibody to further shrink remaining tumors.

Harmonious Outcome: John responds well to treatment, his gastrin levels normalize, and the cancer remains under control. He continues regular monitoring and lifestyle modifications to manage ZES and prevent cancer recurrence.

Takeaway: John’s case highlights the role of gastrin in both ZES and gastric cancer. Early detection, targeted therapies, and a multidisciplinary approach offer hope for managing these complex conditions.

This brief case study personalizes the information about gastrin’s role in GI cancers by focusing on a fictional patient named John. It illustrates the diagnostic process, treatment options, and potential outcomes for individuals with gastrin-related malignancies.
