In Harbin, there is one of the earliest nationally launched, and the most comprehensive database of gastric cancer, led by Yingwei Xue, director of the Department of Gastrointestinal Surgery, Harbin Medical University Cancer Hospital. The database collected detailed information on more than 20,000 patients with gastric cancer since the hospital was established in 1975. From the side, it shows the characteristics and incidence of gastric cancer in Heilongjiang province. In recent years, the proportion of early gastric cancer patients is getting higher. The majority of patients with gastric cancer have the highest incidence in the 56-65 age group. More than half of the patients prefer to eat salty and have a history of smoking. The ratio of male to female patients is about 3:1.
The proportion of early patients in gastric cancer is increasing. From 1975 to 1980, only 2 early patients were found in 5 years. From 2015 to the present, 1077 early patients have been discovered in 4 years. The prognosis of gastric cancer is closely related to the timing of diagnosis. In patients with early gastric cancer, the 5-year survival rate after surgery can exceed 90%. The 5-year survival rate of advanced gastric cancer is still lower than 30-50%, and the treatment effect is poor and the cost is high, which brings a heavy economic and psychological burden to the patient family and society.

Yingwei Xue suggested that when the body suddenly appears unexplained upper abdominal discomfort, rapid loss of appetite, abdominal disability, weight loss, weight loss, anemia, stomach bleeding and other dyspepsia symptoms. You should go to the hospital for examination if you do not relieve the symptoms after taking the medicine.

The trend of youthfulness is obvious, the most patients from 56 to 65 years old. From the 20,386 records in the current database, the most patients in the 56-65 age group.

The occurrence and development of gastric cancer must pass the incubation period of 10 to 20 years. It is the peak stage of gastric cancer development to gastric cancer. However, in the past 10 years, the total number of people under the age of 35 has increased, and the youngest is 19 years old, which is related to bad habits.

From the database, nearly half of the patients have a history of smoking, and more than half of the patients tend to have a "salty" diet.

Yingwei Xue introduced that there are many causes of gastric cancer, the most important of which is the individual's dietary factors. The stomach is an important digestive organ of human beings. The daily diet is the most direct way to cause stomach diseases. Excessive intake of salt, high-salt marinated foods, smoked foods, and nitrosamine compound foods are a related factor in inducing gastric cancer.
