Stomach cancer, also known as gastric cancer, develops when malignant cells form in the stomach’s lining. Understanding the stages of stomach cancer is crucial for early detection, effective treatment, and improved patient outcomes. In this blog, we will discuss the stages of stomach cancer, their symptoms, and the available treatment options to help you stay informed.
What Are the Stages of Stomach Cancer?
The progression of stomach cancer is categorized into five main stages, ranging from Stage 0 to Stage 4. Each stage signifies the extent of cancer spread, and understanding these stages is vital for determining the appropriate treatment plan.
Stage 0: Early-Stage Stomach Cancer
Cancer is confined to the innermost layer of the stomach lining (mucosa) at this stage. It is also known as carcinoma in situ.
Symptoms:
- Often asymptomatic.
- Mild indigestion or discomfort.
Treatment:
- Endoscopic Resection: Removal of cancerous cells using an endoscope.
- Surgery: Partial gastrectomy to remove affected areas if necessary.
Stage 1 Stomach Cancer
Cancer has spread into deeper layers of the stomach but hasn’t reached the lymph nodes extensively.
Stage 1 Stomach Cancer Symptoms:
- Mild abdominal pain.
- Loss of appetite.
- Nausea or vomiting.
Treatment:
- Surgery: Subtotal or total gastrectomy to remove part or all of the stomach.
- Chemotherapy: Administered before or after surgery to kill cancer cells.
- Radiation Therapy: To target residual cancer cells.
Stage 2 Stomach Cancer
Cancer has invaded deeper layers of the stomach and spread to nearby lymph nodes but hasn’t reached distant organs.
Stage 2 Stomach Cancer Symptoms:
- Persistent stomach pain.
- Significant weight loss.
- Difficulty swallowing.
Treatment:
- Combination Therapy: Surgery, chemotherapy, and radiation are typically employed.
- Targeted Therapy: Medications like HER2 inhibitors for specific types of stomach cancer.
Stage 3 Stomach Cancer
At this stage, cancer has spread to all layers of the stomach and nearby organs or lymph nodes.
Stage 3 Stomach Cancer Symptoms:
- Severe abdominal pain.
- Visible swelling in the abdomen.
- Fatigue and anaemia.
Treatment:
- Surgery: May include gastrectomy with lymph node dissection.
- Advanced Chemotherapy: To manage cancer spread.
- Palliative Care: To improve quality of life if curative treatments are not viable.
Stage 4 Stomach Cancer
The most advanced stage is where cancer has metastasized to distant organs such as the liver, lungs, or bones.
Stage 4 Stomach Cancer Symptoms:
- Persistent vomiting, often with blood.
- Severe weight loss and malnutrition.
- Chronic fatigue and jaundice.
Stage 4 Stomach Cancer Treatment:
- Palliative Chemotherapy: To slow cancer growth and alleviate symptoms.
- Targeted Therapy: HER2 inhibitors or immunotherapy to prolong survival.
- Nutritional Support: To manage malnutrition and improve strength.
End Stage Stomach Cancer: What to Expect
End-stage stomach cancer refers to the final progression of Stage 4, where treatment focuses primarily on comfort and quality of life.
Symptoms:
- Severe pain and discomfort.
- Fluid buildup in the abdomen (ascites).
- Inability to eat or drink.
Treatment:
- Palliative Care: Pain management and emotional support.
- Hospice Services: For end-of-life care.
Importance of Early Detection
Early detection can significantly improve survival rates. Regular screenings, particularly for those with a family history of stomach cancer or risk factors like H. pylori infection, are essential.
