Survival Rates After Surgery for Mid-Stage Gastric Cancer

Gastric cancer at the mid-stage typically refers to stage II or stage III of the disease. For patients diagnosed with stage II gastric cancer and receiving standardized treatment, the 5-year survival rate is approximately 55%. On the other hand, for those with stage III gastric cancer, the 5-year survival rate ranges between 15% and 30%. These figures highlight how the prognosis can vary significantly depending on the stage at which the cancer is detected and treated.

Thanks to continuous advancements in medical science, new treatment options have emerged that improve outcomes for patients. In addition to surgical intervention, targeted therapies, immunotherapies, and traditional Chinese medicine approaches are now available, offering a more comprehensive treatment strategy. As a result, patients diagnosed with mid-stage gastric cancer generally have a better 5-year survival outlook compared to those diagnosed at an advanced or late stage.

Early detection plays a critical role in improving survival rates. Patients with stage I gastric cancer often achieve excellent results, with 5-year survival rates reaching as high as 82% to 95%. In particular, patients with mucosal cancer—cancer that has not spread beyond the innermost layer of the stomach lining—may even have a near 100% 5-year survival rate, effectively meaning a full recovery is possible.

Timely diagnosis and treatment significantly improve the prognosis for patients with early-stage gastric cancer. This underscores the importance of regular screenings and early medical intervention, especially for individuals at higher risk. Detecting gastric cancer at an early stage, such as stage I, dramatically increases the chances of successful treatment and long-term survival.

In conclusion, while mid-stage gastric cancer presents greater challenges than early-stage disease, advancements in treatment have improved outcomes. Patients who receive a timely diagnosis and follow a comprehensive treatment plan can experience significantly better survival rates.
