Chinese Researchers Develop Groundbreaking System for Early Stomach Cancer Detection

A significant advancement in medical technology has been achieved by Chinese researchers, who have developed an artificial intelligence system capable of detecting early-stage stomach cancer using standard CT scans. This breakthrough has the potential to revolutionize cancer detection globally.

This development is part of a broader effort by Chinese scientists and technology firms to lead in AI-powered healthcare, with substantial implications for millions at risk of this deadly disease. The GRAPE model, a collaborative effort between Zhejiang Cancer Hospital and Alibaba's DAMO Academy, represents a major step forward in early cancer detection.

The study, published in the journal Nature Medicine, demonstrates the AI's ability to identify stomach tumors from non-contrast CT imaging, a method previously considered less effective for gastric cancer screening. Gastric cancer remains a highly lethal malignancy, particularly in Asia. Early detection is crucial, as patients diagnosed at stage one have a significantly higher survival rate compared to those diagnosed at later stages.

The GRAPE model addresses the limitations of traditional screening methods by utilizing routine CT scans, which are already widely available. The AI was trained on a vast dataset of scans from numerous medical centers across China. The AI achieved high sensitivity in identifying early tumors, surpassing the performance of human radiologists.

In real-world trials, the system significantly increased detection rates. Notably, a substantial percentage of the detected cases were stomach cancer patients without any symptoms. The research team also found that the AI model could detect gastric cancer several months earlier than a diagnosis.

The GRAPE model has already been implemented in hospitals in East China, with plans for wider deployment both within China and internationally. This breakthrough follows China's previous success with PANDA, an AI model designed to detect pancreatic cancer through ordinary CT imaging.

A growing number of Chinese researchers are utilizing AI to address critical health challenges. These systems are already in use at leading institutions, such as Peking Union Medical College Hospital and Shanghai's Ruijin Hospital. These innovations reflect China's strategic investment in advancing AI healthcare solutions.
