Gastric Cancer: Why Chemotherapy Is Necessary After Total Gastrectomy

After undergoing a total gastrectomy for gastric cancer, many patients wonder why further treatment such as chemotherapy is still necessary. Even after complete surgical removal of the stomach, there remains a significant risk of cancer recurrence or metastasis. This is especially true for patients whose cancer had already progressed to involve a larger area of the stomach, necessitating full removal.

One of the main reasons chemotherapy is recommended is to target any remaining cancer cells that may not be visible during surgery. These microscopic cancer cells may have spread to nearby lymph nodes, the abdominal cavity, or even entered the bloodstream. Since these cells are undetectable by standard imaging or tests, chemotherapy becomes a critical tool in eliminating them.

In cases where the tumor is located in the middle of the stomach and has spread widely on both sides, a total gastrectomy is often required. Patients with more advanced stages of gastric cancer are at a higher risk for recurrence and metastasis. That's why adjuvant chemotherapy plays a crucial role in improving long-term outcomes.

Chemotherapy helps increase survival rates and may even contribute to a higher chance of complete recovery. By attacking residual cancer cells post-surgery, it significantly reduces the likelihood of the cancer returning. This treatment is not only about prolonging life but also about enhancing the quality of life by preventing the spread of the disease.

In summary, chemotherapy after total gastrectomy is a vital part of the treatment plan for many gastric cancer patients. It targets hidden cancer cells and improves both survival and cure rates. Understanding its importance can help patients make informed decisions about their post-surgery care.
