Treatment may be any of the following:

1. Surgery to remove part of the stomach (subtotal gastrectomy).
2. Surgery to remove the entire stomach and part of the surrounding tissues (total gastrectomy). Lymph nodes around the stomach may also be removed during surgery (lymph node dissection).

Gastric Cancer - Stage I

Treatment may be any of the following:

1. Surgery to remove part of the stomach (subtotal gastrectomy) with removal of associated lymph nodes (lymphadenectomy)

1. Surgery to remove part of the stomach (subtotal gastrectomy).
2. Surgery to remove the entire stomach and some of the tissue around it (total gastrectomy).
3. A clinical trial of surgery followed by adjuvant radiation therapy, chemotherapy, or both. Lymph nodes around the stomach may also be removed (lymph node dissection).

Gastric Cancer - Stage III

Treatment may be any of the following:

1. Surgery to remove the entire stomach and some of the tissue around it (total gastrectomy). Lymph nodes may also be removed.
2. A clinical trial of surgery followed by adjuvant radiation therapy, chemotherapy, or both.
3. A clinical trial of chemotherapy with or without radiation therapy.
