About this study

Digestive system malignancies are among the most common types of cancers in China, primarily including esophageal cancer, gastric cancer, pancreatic cancer, liver cancer, and colorectal cancer. According to the 2024 National Cancer Registry data released by the National Cancer Center of China (covering a population of 523 million), digestive system tumors (including colorectal, liver, gastric, and esophageal cancers) account for 28.49% of all new cancer cases and 31.77% of total cancer-related deaths in the country. Among these, the incidence and mortality burdens of gastric, esophageal, and liver cancers are significantly higher than the global average. Most patients are diagnosed at an advanced stage, with a five-year survival rate below 30%. This highlights that digestive system malignancies represent a major public health challenge in China, necessitating in-depth studies on their pathogenesis and the development of novel prevention and treatment strategies. At present, radical surgical resection remains the only potentially curative option for digestive system cancers. However, for patients with locally advanced or late-stage disease, surgery alone yields limited efficacy. In recent years, chemotherapy-based neoadjuvant therapy has been increasingly applied in clinical practice to improve R0 resection rates and overall survival \[4-6\]. Nevertheless, current studies show that the response rate to neoadjuvant therapy remains modest, and there is a lack of precise strateg…
