Gastric Cancer Patients Who Had Two-Thirds of the Stomach Removed: What Is the Life Expectancy?

The life expectancy of patients who have had two-thirds of their stomach removed due to gastric cancer largely depends on several critical factors, including the depth of tumor invasion, the presence of lymph node metastasis, and whether distant metastasis has occurred.

Gastric cancer is classified into four stages (I, II, III, and IV) based on how deeply the tumor has invaded the stomach wall. The 5-year survival rates vary significantly across these stages. Patients diagnosed at Stage I have a relatively high 5-year survival rate of approximately 83.3%. In contrast, those at Stage IV face a much lower survival rate of only about 1.8%.

The presence or absence of lymph node metastasis is another key factor influencing prognosis. For patients with lymph node involvement, the 5-year survival rate after surgery drops to around 22%. However, for those without lymph node metastasis, the 5-year survival rate can be as high as 75%.

Early detection and prompt treatment are crucial for improving outcomes in gastric cancer patients. While the type of surgical procedure performed is not strongly linked to prognosis, the completeness of tumor removal, the status of lymph node metastasis, and the depth of tumor invasion are all closely related to long-term survival.

In summary, the overall prognosis after removing two-thirds of the stomach for gastric cancer depends on a combination of factors. Timely diagnosis, comprehensive treatment, and accurate staging are essential for optimizing patient outcomes.
