Treatment Options for Stage 2 Stomach Cancer

The primary treatment options for stage 2 stomach cancer typically include surgery, chemotherapy, and radiation therapy. The choice of treatment and its sequence depend on various factors, including the patient's overall health, age, and the specific characteristics of the tumor.

1. Surgery

• Gastrectomy: This involves the partial or total removal of the stomach, depending on the location and extent of the tumor. Lymph nodes near the stomach are also removed to check for cancer spread.
• Surgical Margins: Achieving clear surgical margins (no cancer cells at the edge of the removed tissue) is crucial for preventing recurrence.

2. Chemotherapy

• Adjuvant Chemotherapy: Administered after surgery to kill any remaining cancer cells and reduce the risk of recurrence.
• Neoadjuvant Chemotherapy: Given before surgery to shrink the tumor, making it easier to remove surgically.
• Common Chemotherapy Drugs: Include fluorouracil (5-FU), cisplatin, oxaliplatin, and docetaxel.

3. Radiation Therapy

• External Beam Radiation: Uses high-energy rays to target and destroy cancer cells. It can be used before or after surgery.
• Concurrent Chemoradiation: Combining radiation therapy with chemotherapy can enhance the effectiveness of both treatments.

Factors Influencing Prognosis

Beyond age, several other factors play a significant role in determining the prognosis for stage 2 stomach cancer patients.

• Tumor Grade: High-grade tumors (more aggressive) tend to have a poorer prognosis compared to low-grade tumors.
• Lymph Node Involvement: The number of lymph nodes affected by cancer is a critical prognostic factor. More involved lymph nodes typically indicate a higher risk of recurrence.
• Surgical Resection: The completeness of surgical removal significantly impacts survival. Achieving clear margins is essential.
