Gastric (Stomach) Cancer

HIGH SEVERITY

Adenocarcinoma of the stomach, often associated with H. pylori infection, smoking, diet (salted/preserved foods), and genetic factors. Incidence declining in West but remains high in East Asia. Lauren classification: intestinal and diffuse types.

Risk Factors

1Age
2Family history
3Genetic mutations
4Smoking
5Alcohol consumption
6Obesity
7Physical inactivity
8Environmental exposures
9Infections (HPV, HBV, HCV, H. pylori)

Diagnostic Methods

  • 1Biopsy
  • 2Imaging (CT, MRI, PET)
  • 3Tumor markers
  • 4Genetic testing
  • 5Endoscopy
  • 6Blood tests
  • 7Screening programs

Prognosis

Improved with early detection. Stage I: 5-year survival 70-90%. Stage II: 5-year survival 50-60%. Stage III: 5-year survival 20-40%. Stage IV (metastatic): 5-year survival 5-10%. Overall 5-year survival approximately 32%. Curative potential with complete surgical resection. Chemotherapy and radiation improve outcomes. HER2-positive tumors respond to trastuzumab. MSI-high tumors respond to immunotherapy. Quality of life maintained with palliative care in advanced disease.

Prevention

  • Smoking cessation
  • Sun protection
  • Healthy diet
  • Regular exercise
  • Vaccination (HPV, HBV)
  • Screening programs
  • Limit alcohol
  • Maintain healthy weight

Research Status

HER2-targeted therapy (trastuzumab) for HER2+ disease. CLDN18.2-targeted therapy (zolbetuximab) approved. Immunotherapy (nivolumab, pembrolizumab) in combination. MSI-H tumors respond well to immunotherapy.
