Can Early and Mid-Stage Stomach Cancer Be Cured?

When it comes to early or mid-stage stomach cancer, the chances of a complete cure are significantly high. For instance, in Japan, where a comprehensive nationwide screening program for stomach cancer exists, many cases are detected at an early stage. This early detection plays a crucial role in successful treatment outcomes.

The earliest stage is classified as Stage I. At this stage, the cure rate is over 90%, meaning the majority of Stage I stomach cancer patients can be cured through surgery or endoscopic removal of the tumor. If the cancer is not detected early, it may progress to Stage II or III, which are considered mid-stages. Stage II stomach cancer is relatively treatable, as the tumor is not overly large and lymph node involvement is limited. In most cases, a combination of surgery and post-operative chemotherapy can lead to a cure, with cure rates ranging from 70% to 80%.

As the disease advances to Stage III, it is often referred to as locally advanced or mid-late stage. While the likelihood of a cure decreases, it is still possible. With radical and standardized surgical procedures followed by regular chemotherapy, there is at least a 50% chance of achieving a cure. However, once the cancer has spread to distant organs—known as Stage IV—the possibility of a complete cure becomes very low. At this stage, treatment focuses mainly on extending life through targeted therapies and chemotherapy.

In summary, early and mid-stage stomach cancer can often be cured, especially when patients receive timely and appropriate treatment. Adhering to standardized treatment protocols is essential for maximizing the chances of recovery.
