Gastric Cancer Staging Is Not Determined By How Much Of The Stomach Is Removed

When it comes to treating gastric cancer, many people wonder whether the amount of stomach removed during surgery indicates the stage of cancer. It's important to understand that gastric cancer staging is not directly related to the volume of the stomach removed during surgery. Instead, the stage is determined by how far the cancer has spread within the body.

There are different types of surgical procedures used in treating gastric cancer, including distal gastrectomy, proximal gastrectomy, and total gastrectomy. In a total gastrectomy, the entire stomach is removed, while in either a distal or proximal gastrectomy, approximately 4/5 of the stomach is removed. Therefore, removing about half of the stomach does not indicate the stage of gastric cancer.

The actual staging of gastric cancer is based on several key factors. One of these is tumor size and how deeply the cancer has invaded the layers of the stomach wall — such as the submucosa, muscularis propria, or serosa. Additionally, whether the cancer has spread to nearby organs plays a crucial role in determining the stage.

Another important factor in staging is lymph node involvement. If cancer cells are found in nearby lymph nodes, this can indicate a more advanced stage. Moreover, the presence of distant metastasis — such as to the liver, lungs, or other organs — is a major determinant in classifying the cancer as stage IV.

In conclusion, the extent of stomach removal during surgery does not define the stage of gastric cancer. Accurate staging requires a comprehensive evaluation of tumor depth, lymph node involvement, and the presence of distant metastases. Patients should always consult with their medical team to understand their specific diagnosis and treatment plan.
