How long can the middle and late stage of pancreatic cancer live cannot be generalized, it is related to the patient’s physical condition, treatment effect, disease stage, etc. Generally speaking, it is in the range of 3~6 months, and patients with good treatment effect may survive for more than one year. The middle and late stage of pancreatic cancer indicates that the tumor has invaded the tissues and organs around the pancreas, and even distant metastases have occurred, so it is generally not possible to perform radical surgery, and only some comprehensive treatment options can be taken, including radiotherapy, chemotherapy, immunotherapy, etc. to prolong the survival time and improve the quality of life. For patients who cannot tolerate these systemic treatment programs, the survival period will be even shorter, and can be given nutritional support, pain relief and other symptomatic treatment, in order to improve the patient’s quality of life. It is recommended that patients actively accept standardized treatment to prolong survival time and improve quality of life.
