The Pancreatology Group of the Chinese Medical Association has developed the concept of high-risk groups for pancreatic cancer, as follows: Those who are older than 40 years of age, with no obvious cause of epigastric fullness and discomfort, abdominal pain, accompanied by weight loss. Those with a family history of pancreatic cancer. Those with sudden onset diabetes, especially atypical diabetes, aged 60 years or older, lacking a family history, without obesity, who quickly become insulin resistant. 40% of pancreatic cancer patients have diabetes at the time of diagnosis. Chronic pancreatitis is an important precancerous lesion in a small percentage of patients, especially chronic familial pancreatitis and chronic calcific pancreatitis; mucinous papillary tumors in the ducts of the pancreas are also precancerous lesions; benign lesions undergoing major distal gastrectomy, especially in those who are more than 20 years postoperative; high risk factors for pancreatic cancer include smoking, heavy alcohol consumption, and long-term exposure to harmful chemicals The risk factors for pancreatic cancer include smoking, heavy alcohol consumption, and long-term exposure to harmful chemicals. If abnormalities are found in the pancreas, pancreatic scan with enhanced CT should be performed to clarify the diagnosis as soon as possible, and surgical resection should be performed to achieve the goal of cure. In clinical practice, we often encounter many patients with epigastric fullness and discomfort and abdominal pain, which are misdiagnosed as chronic gastritis and given symptomatic treatment that is ineffective, and then imaging is performed when the symptoms are obviously aggravated and unbearable, and the cancer is already locally advanced and cannot be removed.
