Dependson stage. The treatment and survival depends on how deep the cancer has penetrated the wall of the stomach, and if there is any spread beyond the stomach. For very early stomach cancer, after surgery, there is about a 70% chance of surviving 5 years. This drops to 30-40% if the cancer has spread to the lymph nodes, and about 5% if there is spread to other organs. Not all patients are candidates for surgery.
