Survival from chemotherapy in elderly pancreatic cancer patients cannot be fully assessed, but elderly patients are often inoperable and survival time is often less than 1 year. Pancreatic cancer is a malignant tumor of the digestive tract with insidious onset, rapid progression, and extremely poor therapeutic effect and prognosis. Early symptoms of pancreatic cancer are not obvious, and when conscious symptoms appear or diagnosis is confirmed, it is mostly in the middle or late stage, which is easy to lose the best time for treatment. The prognosis of pancreatic cancer is related to the nature of the tumor, the stage (size, infiltration range, metastasis, etc.), the treatment mode, the patient’s own situation and other factors. The prognosis of malignant tumors is usually described by the survival rate of several years after diagnosis, such as 1-year survival rate, 5-year survival rate and so on. The prognosis of pancreatic cancer varies from person to person, and there is no uniform standard or accepted conclusion. Some studies claim that the prognosis of pancreatic cancer is extremely poor, with an overall 5-year survival rate of only about 8%. Other studies claim that the 1-, 2-, and 3-year survival rates for pancreatic cancer are 21.5%, 6.0%, and 4.0%, respectively, and the overall median survival is only 5.5 months (50% of patients survive). Elderly patients who cannot be treated surgically have an even worse prognosis. If pancreatic cancer is diagnosed, it is recommended to go to a regular hospital for evaluation of the disease and follow the doctor’s instructions for treatment to avoid delays.
